Description

Tent foot structure Technical field

 The present invention relates to a tent, and more particularly to a tent foot structure.

Background technique

Folding tents are easy to carry and collect because they have the function of unfolding and folding. They are not only used as camping items, but also used in outdoor temporary places.

At present, the large-scale pavilion-style tents and tent supports have various structural forms, and the changes mainly focus on the changes of the canopy brackets. The basic requirements for the pursuit are mostly strong support. As shown in FIG. 1 , the existing large gazebo tent, in which the vertical rod 1 ′ as the supporting awning bracket is basically a telescopic structure using inner and outer sleeves, and the outer sleeve 12 ′ of the telescopic structure is located after the tent is deployed. The upper position of the inner sleeve 11' is located below the tent after deployment, so as to ensure that the support slider 5' of the side strut group 3' can be smoothly slid on the strut 1' for positioning and driving. The side strut group 3' is folded.

Due to the large supporting area of the large pavilion tent, the vertical rod 1' is subjected to a large supporting force, and the thin inner casing 11' is located at the bottom of the tent, so that the whole tent has a top-heavy feeling, the tent vertical rod 1 'If the bottom inner sleeve 11' encounters a lateral outward force, its ability to fix the support is necessarily weaker than that of the thick outer sleeve. Therefore, the telescopic structure of the vertical rod 1' currently makes the large pavilion tent still have some safety. Hidden dangers.

Summary of the invention

The object of the present invention is to provide a tent foot structure, which can effectively ensure the folding of the tent frame, improve the support strength of the tent vertical pole, and increase the safety of the tent use.

To achieve the above object, the solution of the present invention is:

A tent foot structure, the tent bracket comprises at least four vertical rods, an overhead frame supported by the vertical rods, and a side support rod group matched between the vertical rods; a cross rod or a side support rod group of the side support rod group The cross rod and the roof rack are respectively coupled to the vertical rod through the fixing block and the slider; wherein: each vertical rod includes a top tube, a middle tube and a lower tube, wherein the upper end of the middle tube is connected with the lower end of the top tube, The sleeve of the middle tube is placed in the lower tube, the tube for the same tube diameter is the tube tube, and the slider is positioned on the tube, and the lower portion of the tube and the upper portion of the tube are unfolded. Positioning means.

The slider positioning mechanism includes an elastic button pivotally connected to the slider and an elastic positioning member located in the top tube.

The elastic positioning member comprises a spring piece and a convex piece which is driven by the elastic piece to extend and contract with the positioning hole of the top pipe and the slider.

The positioning device includes an elastic positioning pin disposed in a lower portion of the middle tube and a fitting hole formed in an upper portion of the lower tube.

After adopting the above scheme, since the tent legs of the present invention are composed of three pipe fittings of a top pipe, a middle pipe and a lower pipe, the middle pipe and the lower pipe constitute an inner and outer telescopic structure to meet the tent folding requirements, and at the same time, the thinner middle pipe is It is disposed at the upper position of the vertical rod, and the thick lower tube is disposed at the lower position of the vertical rod to ensure the support strength after the tent is deployed, and to increase the stability and safety of the tent; the other tube is the same tube as the lower tube The arrangement of the diameter pipe body can satisfy the smooth movement of the slider of the linkage side strut group or the roof rack on the vertical pole, and ensure the normal implementation of the tent display function.

detailed description

As shown in FIG. 2 to FIG. 3, the present invention discloses a tent foot structure, which is a gazebo tent, which can be a large tent or a small tent, wherein the tent bracket includes at least four vertical rods 1. The roof rack 2 supported by the rod 1 and the side strut group 3 fitted between the vertical rods 1; the side strut group 3 is constituted by at least one set of intersecting rods 31, which in this embodiment is composed of two sets of intersecting rods 31 At the same time, the roof rack 2 in this embodiment is pivotally connected to the side strut group 3, that is, the side strut group 3 is interlocked, and the cross rods 31 of the side strut group 3 are respectively passed through the fixed block 4 and the slider 5. Fitted on the vertical rod 1, of course, the roof rack 2 can also be directly pivotally matched with the fixed block 4 and the slider 5; the key of the present invention is:

Each of the vertical rods 1 includes a top tube 11, a middle tube 12 and a lower tube 13, wherein the upper end of the middle tube 12 is connected with the lower end of the top tube 11, and the middle tube 12 and the lower tube 13 constitute an inner and outer telescopic sleeve structure, that is, the middle tube 12 and the lower tube 13 are in a movable sleeve matching structure, and the top tube 11 and the lower tube 13 are tube bodies of the same diameter, and the top tube 11 and the lower tube 13 form a tube body for the slider to be actively engaged; on the top tube 11 A slider positioning mechanism 51 is provided, and the lower portion of the middle tube 12 and the upper portion of the lower tube 13 are provided with positioning means 6 for both.

As shown in FIG. 2A, the slider positioning mechanism 51 includes an elastic button 511 pivotally connected to the slider 5 and an elastic positioning member 512 located in the top tube 11. The elastic positioning member 512 includes a resilient piece 513 and is stretched by the elastic piece 513. The ribs 514 of the positioning holes (not shown) of the top tube 11 and the slider 5.

The positioning device 6 includes an elastic positioning pin disposed in a lower portion of the middle tube 12 and a fitting hole formed in an upper portion of the lower tube 13.

When the tent of the present invention is deployed, each side strut group 3 will drive the slider 5 to slide onto the top tube 11 when the tent is deployed. After the slider 5 is positioned by the slider positioning mechanism 51, the side support rod of the tent The group 3 is in a fully deployed state, and the undercarriage 2 is also in a fully deployed state; after that, the middle tube 12 is pushed out from the lower tube 13 until the lower portion of the middle tube 12 is moved to the upper portion of the lower tube 13, and the two are positioned. The device 6 is positioned so that the deployed state of the entire tent is completed.

On the other hand, when the tent is folded, the positioning relationship between the center tube 12 and the lower tube 13 of the positioning device 6 is first released, and the middle tube 12 is folded into the lower tube 13, and the lower tube 13 is docked with the top tube 11, which When the positioning relationship of the slider positioning mechanism 51 to the slider 5 is released, the poles of the tent can be gathered together to complete the folding operation of the tent.

It can be seen that the tent legs of the present invention are composed of a three-section pipe member of the top pipe 11, the middle pipe 12 and the lower pipe 13, and the middle pipe 12 and the lower pipe 13 constitute an inner and outer telescopic structure to meet the tent folding requirements, and at the same time, a thinner The middle tube 12 is disposed at an upper position of the vertical rod 1, and the thick lower tube 13 is disposed at a lower position of the vertical rod 1, ensuring the support strength after the tent is deployed, and increasing the stability and safety of the use of the tent; The tube 11 and the lower tube 13 are arranged in the same tube diameter, which can satisfy the smooth movement of the slider 5 of the linkage side strut group 3 or the roof rack 2 on the vertical rod 1, and ensure the normal implementation of the tent display function.
