Description

A blow molding panel and a folding table using the panel

technical field

The invention relates to a panel and a folding table using the panel, in particular to a blow molding panel and a folding table using the blow molding panel.

Background technique

Blow molding products are light in weight due to their hollow structure. In addition, due to their material, shape and structure, they have the advantages of strong rigidity, good impact resistance, and not easy to damage. In recent years, blow molding products have been widely used in many fields. use. For example, there are various blow molding tables, blow molding chairs, blow molding stools, etc. in outdoor furniture products.

Taking the blow molding table as an example, it is usually made of a blow molding panel and a foldable iron bracket. The existing blow molding table often uses such a blow molding panel, which is distributed at the bottom of the blow molding panel There are many concave support points, but because the support points are arranged in parallel at the bottom of the blow-molded panel, it is easy to twist in the direction along which the support points are arranged in parallel, so that the structural strength of the panel is not high. In order to improve the structural strength, people have improved the distribution structure of the above-mentioned concave support contact points. For example, at the bottom of the blow-molded panel, there are many support contact points that are arranged randomly and have different shapes and sizes. The structural strength of the blow-molded panel has a certain effect, but there is still room for further improvement in the structural strength, and this invisible arrangement also makes the back of the panel unattractive.

In addition, people also increase the structural strength of the blow-molded panel by increasing the thickness of the blow-molded panel. However, the defect of using a thickened panel is that the panel looks thicker. Not only is it bulky, but it is also beneficial to save costs.

Contents of the invention

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

The second technical problem to be solved by the present invention is to provide a folding table with a blow-molded panel with a novel structure and sufficient rigidity and strength in view of the above-mentioned current state of the art.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: the blow molding panel has many depressed support contact points distributed on the back of the panel, and the feature is that the support contact points adjacent on the same longitudinal line and on the same horizontal line The adjacent support contact points on the line are distributed in a criss-cross pattern.

Further preferably, the support contact point is strip-shaped, and two reinforcing ribs are arranged in the support contact point, and correspondingly, three contact points are arranged in the support contact point and arranged at intervals with the reinforcing ribs. In this way, not only can the structural strength of the supporting contact point be improved, and the distortion of the panel can be reduced, but also the area of the contact point can be reduced, preventing scars on the surface of the panel, and improving the flatness of the surface of the panel.

In order to improve the structural strength at the corners of the panel, four corners on the back of the panel are respectively provided with a corner support contact point with a linear inner side and an arc-shaped outer side.

In order to further improve the structural strength at the corners of the panel, two or more oblique reinforcing ribs are provided in the corner supporting points.

Further preferably, a first strip-shaped groove adjacent to the flange is respectively provided on two opposite sides of the back of the panel, and a second strip-shaped groove is provided between corresponding ends of the two first strip-shaped grooves. The support contact points in the one-shaped slot and the second strip-shaped slot are arranged uniformly or in a criss-cross arrangement in turn. The first strip-shaped groove and the second strip-shaped groove are respectively used for installing the longitudinal beam and the cross beam, and the support contact points in the first strip-shaped groove and the second strip-shaped groove can further improve the rigidity and structural strength of the panel.

In order to facilitate the folding of the tripod of the folding table matched with the panel, a plurality of bar-shaped grooves are formed in the area surrounded by the first bar-shaped groove and the second bar-shaped groove on the back of the panel. The supporting contact points inside are arranged uniformly or criss-cross in sequence, and the tripod used with the blow-molded panel is folded and embedded in the strip-shaped groove. The support contact points located in the bar grooves further increase the rigidity and structural strength of the panels.

A folding table using the above-mentioned blow-molded panel, including longitudinal beams, cross beams and tripods. fixed, there are two crossbeams, which are respectively embedded in the second bar-shaped groove and the two ends of the crossbeam are respectively fixed on the longitudinal beams, and the tripod is foldable and installed On the two beams, the tripod is embedded in the strip-shaped groove in the folded state. After adopting the above-mentioned structure, the structure of the folding table is firmer, and it is more convenient to fold.

The longitudinal beam installed in the first strip-shaped groove can adopt various structures. Preferably, the longitudinal beam is in the shape of "╗", and the upper part of the longitudinal beam is embedded in the first strip-shaped groove. The lower outwardly bent part sits on the step of the inner layer of the flange and at the same time collides laterally with the lower part of the inner layer of the flange. When the folding table is in the folded state, 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 longitudinal beam is flush with the lower bottom surface of the flange.

Compared with the prior art, the present invention has the following advantages: firstly, the hollow blow-molded panel is provided with criss-cross support contact points on the back, not only the structure is relatively novel, but also the panel can be made very thin. Ensure the rigidity and strength of the panel and reduce the production cost; secondly, through the first bar-shaped groove, the second bar-shaped groove and the bar-shaped groove on the back of the panel, the installation of the tripod is more convenient and firm, and the panel and the tripod After being fully folded, it can maintain a good flatness, which makes it easier for multiple folding tables to be stacked after being folded.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 to 4, the blow-molded panel in this embodiment is distributed with numerous depressions on the back and is arranged in a criss-cross pattern. The support points 2 are in the shape of strips. The principle of mechanics effectively decomposes the external stress in one direction into forces that are mutually involved in multiple directions, thereby enhancing the structural strength and twist resistance of the panel itself, and, after adopting the concave support contact point 2, it can reduce blowing The wall thickness of the plastic panel reduces the weight of the panel. Especially for ultra-thin (thickness<40MM) boards, after adopting criss-cross support contact points 2, its firmness can be greatly strengthened, making it difficult to deform. In addition, in order to improve the structural strength of the contact point 2, generally two reinforcing ribs 21 can be arranged in a supporting point 2, correspondingly, the contact point 22 of the supporting point 2 is three and arranged at intervals with the reinforcing ribs 21, thereby Reducing the area of the contact point 22 makes it difficult to produce scars on the front 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 contact points 2, only one reinforcing rib or more than two reinforcing ribs may be provided in individual support contact points.

In order to improve the structural strength at the corners of the panel, a corner support touch point 3 with a linear inner side and an arc-shaped outer side is respectively provided at the four corners on the back of the panel, and, in order to further improve the corner support For the structural strength of the bump, in this embodiment, three oblique reinforcing ribs 31 are provided in each corner support bump 3 .

Similar to a conventional panel, the blow molding panel extends downwards to form a flange 1 around it. Since the periphery of the blow molding panel is a relatively vulnerable part, in order to ensure its strength and impact resistance, in this embodiment, the flange 1 adopts Double-layer structure, the flange outer layer 12 is straight-walled, the upper part of the flange inner layer 11 and the upper part of the flange outer layer 12 are hollow, the lower part of the flange inner layer 11 and the lower part of the flange outer layer 12 Specifically, the lower part of the flange inner layer 11 is bent toward the flange outer layer 12 in a step shape and then bent downward, and the flange inner layer 11 and the flange outer layer 12 of the downwardly bent part The lower part is glued together. Preferably, the height of the bonding part between the flange inner layer 11 and the flange outer layer 12 at the lower part of the flange accounts for 1/5 to 1/4 of the entire flange height, so that the structural strength of the flange 1 can be ensured. , and it is convenient for the longitudinal beam to be installed and fixed.

Two opposite sides on the back of the panel are respectively provided with a first strip-shaped groove 4 adjacent to the flange 1, and a second strip-shaped groove 5 is arranged between the corresponding ends of the two first strip-shaped grooves 4, and the first strip-shaped groove 5 is arranged between the corresponding ends of the first strip-shaped groove 4. The supporting contact points 2 in the strip-shaped groove 4 and the second strip-shaped groove 5 are uniformly arranged sequentially or arranged in a criss-cross pattern. A plurality of strip-shaped grooves 6 are formed in the area surrounded by the first strip-shaped groove 4 and the second strip-shaped groove 5 on the back of the panel, and the support contact points 2 in the strip-shaped grooves 6 are uniformly arranged in sequence or criss-crossed Arranged, and the tripod used in conjunction with the blow molding panel is folded and embedded in the strip groove 6 .

As shown in Figures 5 to 7, the folding table with blow-molded panels in this embodiment includes longitudinal beams 7, crossbeams 8 and tripods 9, wherein there are two longitudinal beams 7, which are respectively embedded in the first In the shaped groove 4 and fixed with the top of the flange inner layer 11, there are two crossbeams 8, which are respectively embedded in the second bar-shaped groove 5 and the two ends of the crossbeam 8 are respectively fixed on the longitudinal beam 7, and the tripod 9 is The tripod can be folded and installed on the two beams 8, and the tripod 9 is embedded in the bar-shaped groove 6 in the folded state. The movable foldable tripod is basically the same as the tripod structure of the existing table legs, and will not be repeated here. After the tripod is folded 9 times, the panel and the tripod can maintain a good flatness after being completely folded, so that multiple folding tables can be stacked more easily after being folded. In addition, in order to further improve the impact resistance of the flange 1, the longitudinal beam 7 is in the shape of "╗". On the step of the inner layer of the flange and at the same time collide with the lower part of the inner layer of the flange laterally, and the lower bottom surface 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. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, various modifications or improvements can be made to the present invention, such as the support of the touch point. The shape is not limited to the structures given in this embodiment, and these are all considered within the protection scope of the present invention.
