Description

Blow molding panel and folding table using the same

The present invention relates to a panel and a folding table using the same, and more particularly to a blow molding panel and a folding table using the same. Background technique

The blow molded product has a hollow structure and is light in weight. Moreover, due to its material, shape and structure, it has the advantages of high rigidity, good impact resistance, and not easy to be damaged. In recent years, blow molded products have been widely used in many fields. use. For example, outdoor furniture items include various blow molding tables, blow molding chairs, and blow molding stools.

For example, in the case of a blow molding table, it is usually made of a blow molded panel and a collapsible iron bracket. The existing blow molding table often adopts such a blow molding panel and is distributed at the bottom of the blow molding panel. There are a large number of concave support bumps, but since the support bumps are arranged in parallel at the bottom of the blow molding panel, it is easy to be twisted in the direction in which the support bumps are arranged in parallel, so that the structural strength of the panel is not high. In order to improve the structural strength, the distribution structure of the support points of the above-mentioned depressions is improved. For example, at the bottom of the blow-molded panel, a plurality of support bumps of irregular arrangement and different shapes are distributed, although the structure is improved. The structural strength of the blow molded panel has a certain effect, but there is still room for further improvement in structural strength, and this intangible arrangement also makes the back of the panel appear not aesthetically pleasing.

In addition, the structural strength of the blow molded panel is increased by increasing the thickness of the blow molded panel. However, the disadvantage of using a thickened panel is that the panel is thicker, and accordingly, the blower is thickened. The table is not only cumbersome, but also helps to save costs. Summary of the invention

The first technical problem to be solved by the present invention is to provide a blow molded panel which is novel in structure, has sufficient rigidity and strength, in view of the above state of the art.

A second technical problem to be solved by the present invention is to provide a folding table using a blow molded panel having both a novel structure and sufficient rigidity and strength in view of the above state of the art.

The technical solution adopted by the present invention to solve the above first technical problem is as follows: The blow molding panel has a plurality of concave supporting contact points distributed on the back surface of the panel, wherein: the supporting bump points are vertically and horizontally staggered.

Further preferably, the supporting touch points are strip-shaped, and two reinforcing ribs are arranged in the supporting touch points. Correspondingly, three contact points are arranged in the supporting touch points and are arranged at intervals from the reinforcing ribs. In this way, not only can the structural strength of the supporting touch point be increased, the distortion of the panel can be reduced, but also the contact point area can be made small, and the surface of the panel can be prevented from being scarred. The flatness of the panel surface is increased.

In order to increase the structural strength at the corners of the panel, the four corners on the back side of the panel are respectively provided with a corner supporting the touch point on the inner side and a curved side on the outer side.

In order to further increase the structural strength at the corners of the panel, two or two upper diagonal reinforcing ribs are provided in the corner supporting contact points.

Further preferably, a first strip-shaped groove adjacent to the flange is disposed on each of opposite sides of the back surface of the panel, and a second strip-shaped groove is disposed between the corresponding ends of the two first strip-shaped grooves, The support points in the one-shaped groove and the second-shaped groove are evenly arranged in sequence or vertically and horizontally. The first and second strips are used to mount the stringers and beams, respectively, and the support points in the first and second strips further increase the rigidity and structural strength of the panel.

In order to facilitate folding of the tripod of the folding table matched with the panel, a plurality of strip-shaped grooves are formed in the area of the back surface of the panel which is formed by the first strip groove and the second strip groove, in the strip groove The inner support bumps are evenly arranged or arranged in a crisscross manner, and the tripods used in conjunction with the blow molding panel are folded and embedded in the strip grooves. The support bumps located in the strip grooves further increase the rigidity and structural strength of the panel.

The technical solution adopted by the present invention to solve the above second technical problem is: a folding table using the above blow molding panel, comprising a longitudinal beam, a beam and a tripod, wherein the longitudinal beams are two, respectively embedded in the The first strip groove is fixed to the upper portion of the inner layer of the flange, and the two beams are respectively embedded in the second strip groove, and the two ends of the beam are respectively fixed to the longitudinal direction. On the beam, the tripod is a foldable stand and is mounted on two beams, and the stand is embedded in the strip groove in a folded state. After adopting the above structure, the structure of the folding table is relatively firm, and the folding is convenient.

The longitudinal beam installed in the first strip groove may adopt various structures. Preferably, the longitudinal beam has an L-shaped cross section, and a vertical portion of the longitudinal beam is embedded in the first strip-shaped groove, longitudinal The lateral portion of the beam sits on the step of the inner layer of the flange and simultaneously collides with the lower portion of the inner layer of the flange. When the folding table is folded, the longitudinal beam embedded in the first strip groove can effectively improve the impact resistance of the flange.

In order to make the folded folding table easier to stack, the lower bottom surface of the stringer is flush with the lower bottom surface of the flange.

Compared with the prior art, the advantages of the present invention are as follows: Firstly, the hollow blow molded panel is provided with support bumps arranged in a crisscross manner on the back surface, which is not only relatively novel in structure, but also can be made on the premise that the panel is made thin. The rigidity and strength of the panel are ensured, and the production cost is reduced. Secondly, the first frame groove, the second strip groove and the strip groove provided on the back surface of the panel make the tripod convenient and firm, and the panel and the stand It maintains a good flatness after being completely folded, which in turn makes it easier to stack multiple folding tables after folding.

The invention will be further described in detail below with reference to the embodiments of the drawings.

As shown in FIG. 1 to FIG. 4, the blow-molded panel of the present embodiment has a plurality of recesses distributed on the back surface and a supporting contact point 2 arranged in a crisscross pattern. The supporting bumps 2 are in the shape of a strip, and the cross-hatching is used to cross the cross. The mechanics principle effectively decomposes the external stress in one direction into the forces involved in each other in multiple directions, thereby enhancing the structural strength and the anti-distortion of the panel itself, and by using the concave support bump 2, the blowing can be reduced. The wall thickness of the plastic panel reduces the weight of the panel. Especially for ultra-thin (thickness <40MM) plate body, the use of criss-crossing support bump 2 can greatly enhance its firmness and make it less deformable. In addition, in order to increase the structural strength of the contact bump 2, two reinforcing ribs 21 can be generally disposed in one supporting bump 2, and correspondingly, the contact points 22 supporting the bump 2 are three and spaced apart from the reinforcing rib 21, thereby By reducing the area of the contact point 22, it is less likely to cause scars on the front surface of the panel, which not only improves the flatness of the panel surface, but also reduces the distortion of the panel. Of course, according to the specific arrangement of the support touch points 2, only one reinforcing rib or two or more reinforcing ribs may be provided in the individual support touch points.

In order to improve the structural strength at the corners of the panel, at the four corners of the back of the panel, a corner supporting the point 3 on the inner side is linear and the outer side is curved, and, in order to further improve the corner support In the present embodiment, three oblique reinforcing ribs 31 are provided in each of the corner supporting bumps 3.

Similar to the conventional panel, the blow molding panel is extended downwardly to form the flange 1. Since the periphery of the blow molding panel is a relatively easy to break portion, in order to ensure the strength and impact resistance, in the embodiment, the flange 1 is adopted. The double-layer structure, the flange outer layer 12 has a straight wall shape, and the upper portion of the flange inner layer 11 and the upper portion of the flange outer layer 12 are hollow, and the lower portion of the flange inner layer 11 and the lower portion of the flange outer layer 12 Adhesively, specifically, the lower portion of the flange inner layer 11 is bent in a step shape toward the flange outer layer 12 and then bent downward, and the flange inner layer 11 and the flange outer layer 12 of the lower portion are bent downward. The lower part is stuck. Preferably, the height of the portion of the flange inner layer 11 located at the lower portion of the flange and the flange outer layer 12 occupies 1/5 to 1/4 of the height of the entire flange, so that the structural strength of the flange 1 can be ensured. Moreover, it is convenient for the longitudinal beam to be installed and fixed.

a first strip-shaped groove 4 adjacent to the flange 1 is disposed on each of the opposite sides of the back surface of the panel, and a second strip-shaped groove 5 is provided between the corresponding ends of the two first strip-shaped grooves 4, at the first The support bumps 2 in the strip-shaped grooves 4 and the second strip-shaped grooves 5 are evenly arranged in sequence or vertically and horizontally. A plurality of strip-shaped recesses 6 are formed in a region surrounded by the first strip-shaped groove 4 and the second strip-shaped groove 5 on the back surface of the panel, and the support bumps 2 in the strip-shaped recesses 6 are evenly arranged or criss-crossed in sequence. Arranged, the tripod used with the blow molding panel is folded and embedded in the strip groove 6.

As shown in FIG. 5 to FIG. 7, the folding table using the blow molding panel in the embodiment includes the longitudinal beam 7 and the beam 8 And the tripod 9, wherein the longitudinal beams 7 are two, respectively embedded in the first strip-shaped groove 4 and fixed to the upper portion of the flange inner layer 11, the two beams 8 are respectively embedded in the second strip groove 5 and both ends of the beam 8 are respectively fixed on the longitudinal beam 7, and the stand 9 is a foldable stand and is mounted on the two beams 8, and the stand 9 is embedded in the strip groove 6 in the folded state. The movable folding stand is basically the same as the stand structure of the existing table leg, and will not be described here. After the tripod 9 is folded, the panel and the stand can maintain a good flatness after being completely folded, so that the plurality of folding tables can be stacked more easily after being folded. Further, in order to further improve the impact resistance of the flange 1, the longitudinal beam 7 has an L-shaped cross section, the vertical portion 71 of the longitudinal beam 7 is embedded in the first strip-shaped groove 4, and the lateral portion 72 of the longitudinal beam 7 is seated in the convex shape. The step of the inner layer of the inner layer simultaneously faces the lower side of the inner layer of the flange, and the lower bottom surface 73 of the longitudinal beam 7 is flush with the lower bottom surface of the flange 1.

The above description is only a preferred embodiment of the present invention, and it should be noted that various modifications or improvements can be made to the present invention without departing from the principles of the present invention, such as supporting a touch point. The shape is not limited to the structure given in the embodiment, and these are all considered to be within the scope of the present invention.
