Abstract

The utility model provides a folding table, comprising a table top and table legs, wherein the table legs are arranged under the table top by hinging, the table top is a hollow structure which is made by blow moulding, the lower end surface of the table top is equipped with a plurality of indentations which are spacedly arranged and are extended to the upper end surface of the table top, the indentation comprises side walls and a tail end, the side walls of each indentation are obliquely arranged in relation to the upper end surface, the height H of each indentation is the vertical distance from the lower end surface to the tail end of the indentation; and all the indentations are arranged into the following model: the distance D between the adjacent indentations is more than three times of height H of the indentation, namely, D is more than 3 H; furthermore, D is not more than 50 mm but not less than 15 mm (excluding 15 mm), and H is less than 17 mm but more than 5 mm. The folding table provided by the utility model has the advantages that the distances among the indentations are more than that of the prior art in case that the bearing strength is same and the depth of the indentation is determined, the density of the indentation is reduced, the process is simple, the manufacturing cost is low, the tail end of the indentation is extended upwards to form a bulge which is formed together with the indentation, the bearing capability of the product is increased, and the supporting strength is met, the production process is convenient and the effect is the optimal due to the ranges of the parameter values of D and H which are determined in the folding table provided by the utility model.

Description

Folding table

(1) technical field

The utility model relates to a kind of folding table, relates 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 utility model provides a kind of novel folding table, and under the situation of same bearing strength, the processing density of desktop depression is less, technology is simple, and cost of manufacture is low.

For this reason, the utility model is taked 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 utlity model has following advantage: 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 the utility model folding table;

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.

Claims
