Abstract

The invention discloses a folding table, which comprises a table top and table legs. The table legs are arranged below the table top in a hinging way; the table top has a hollow structure manufactured in a blow-molding way; a plurality of recesses extended to the upper end face of the table top are distributed on the lower end face of the table top at intervals; each recess comprises a sidewall and a tail end; the sidewalls of each recess are arranged obliquely relative to the upper end face; the height H of each recess is a vertical distance from the lower end face to the tail end of the corresponding recess; and all the recesses are arranged in a way that a distance D between every two recesses is triple as great as that of the height H of the recess, namely, D is more than 3H, wherein D is less than or equal to 50 mm and is more than 15 mm; and H is less than 17 mm and is more than 5 mm. Under the condition of the same bearing strength, when the depth of the recess is fixed, the distance between every two recesses of the folding table may be greater than that in the prior art, so the density of the recesses is reduced, a process is simple and manufacturing cost is low; bumps integrated with the tail ends of the recesses are extended upwards from the tail ends of the recesses, which enhances the bearing capacity of the product; and ranges of the set parameter values D and H of the folding table satisfy supporting strength, make the folding table convenient to machine and produce and achieve optimal effect.

Description

Folding table

(1) technical field

The present invention relates to a kind of folding table, relate in particular to the table top set-ups that blowing is made.

(2) background technology

Existing common folding table, desktop generally all blowing make.Traditional blow-molded plastic all is low intensive relatively, can't support relatively large weight or pressure.In order to increase the intensity of traditional blow-molded article, general way is to add reinforcement.Reinforcement is often made by metal material, because metal has high strength.But shortcoming is that metal ribs must be connected with desktop by mechanical fastener such as bolt or screw, and there is complex manufacturing technology in this structure, shortcomings such as cost height.China Patent No. is 03803188.4, patent name is that portable high-strength blow-molded plastic discloses a kind of desktop, strengthen the bearing strength of product by depression is set, the separation distance between adjacent recessed must satisfy, and is less than or equal to three times of distance between the desktop upper and lower end face.The desktop of this parameter request, depression processing density is big, the processing technology complexity, and, the cost of manufacture height.

(3) summary of the invention

Big in order to solve the desktop processing density that has folding table now, complex process, the shortcoming that cost of manufacture is high the invention provides a kind of novel folding table, and under the situation of same bearing strength, the processing density of desktop depression is less, and technology is simple, and cost of manufacture is low.

For this reason, the present invention takes following technical scheme:

A kind of folding table, include desktop and table leg, described table leg is hingedly mounted on the desktop below, described desktop is the hollow structure that blowing is made, the lower surface of described desktop is furnished with some depressions that extend to the desktop upper surface at interval, described depression includes sidewall and end, the relative upper surface of the sidewall of each depression is and is in tilted layout, the height H of each depression is to the terminal vertical range of depression from the lower surface, all depressions are aligned to following pattern: the distance separating D of institute is greater than three times of depression height H between adjacent recessed, that is D＞3H; And, 50mm 〉=D＞15mm, 17mm＞H＞5mm.

The described adjacent recessed distance separating D of institute is air line distance between edge that two depressions are terminal and the edge.

The end of described depression has extended upward projection.

Employing the present invention have the following advantages: 1, under the situation of same bearing strength, when cup depth one timing, the depression spacing can be big than the spacing of prior art, and depression density reduces, and technology is simple, and cost of manufacture is low; 2, the end in depression has extended upward integrated with it projection, has strengthened the load performance of product; 3, during parameter is set, 50mm 〉=D＞15mm, 17mm＞H＞5mm, the D of this scope and H value can satisfy support strength, are convenient to processing, best results again; 4 is simple in structure, and result of use is good.

Fig. 1 is the desktop lower surface schematic diagram of folding table of the present invention;

Fig. 2 is A place enlarged drawing;

Fig. 3 is the depression profile.

(5) specific embodiment

Embodiment one:

Exhibition accompanying drawing 1-3 folding table, include desktop and table leg, described table leg is hingedly mounted on the desktop below, described desktop is the hollow structure that blowing is made, the lower surface 1 of described desktop is furnished with some depressions 2 that extend to the desktop upper surface at interval, described depression includes sidewall 21 and terminal 22, the relative upper surface of the sidewall of each depression is and is in tilted layout, the height H of each depression is to the terminal vertical range of depression from the lower surface, all depressions are aligned to following pattern: the distance separating D of institute is greater than three times of depression height H between adjacent recessed, that is D＞3H; The described adjacent recessed distance separating D of institute is an air line distance between terminal edge of two depressions and the edge, and, D=50mm, H=16mm.

Embodiment two:

D=16mm, H=5mm, other are with embodiment one.

Embodiment three:

With reference to Fig. 1-3, the end of described depression does not have projection, and other are with embodiment one.

The table top set-ups that this folding table relates to also can be applied to fields such as backboard.
