Description

Technical Field

[0001] The utility model relates to the field of wire mesh turnover boxes, in particular to a frame connection structure used for storage fences. Background Art

[0002] In the logistics and warehousing industry, round tube outer frame products are widely used in wire mesh turnover box WP products. Wire mesh turnover box WP products are usually fence-type, consisting of four parts: front door, back, left side, and right side door. Each part is connected by hinged round tubes and pins to form an independent fence product. In order to facilitate stacking, occupy space, and reduce transportation costs, such products need to be folded and combined for stacking during transportation. However, due to the structural defects of the existing connection method of this product (see Figure 3 ), the pin connects the front door hinge tube and the left door hinge tube together without a certain gap above and below, which causes a jam between the hinge tube and the side frame when folding.

[0003] In order to solve the above problems, engineers and technicians designed a structure that flattens the outer frame at the hinge position. After flattening and assembly, a certain gap will be reserved between the connecting tube and the fence, thus solving the problem of folding jamming during stacking. Utility Model Content

[0004] The purpose of the utility model is to provide a frame connection mechanism to solve the jamming problem caused by stacking wire mesh turnover box WP products in the background art.

[0005] In order to solve the problems mentioned in the background technology, the following method is adopted to achieve: a frame connection structure for a storage fence, the storage fence includes a front door, two symmetrical side doors and a rear door;

[0006] The frame connection structure is used to fold the front door and side door of the fence to the rear door and then fold them for use when stacking and storing; the front door, side door and rear door are respectively composed of a middle wire mesh part and an upper frame, side frame and lower frame fixedly connected to the wire mesh part on all sides; the frame connection structure includes a front door side frame, a rear door side frame and left-right symmetrical side door side frames, a front door hinge tube movably connecting the front door side frame and the side door side frames, a side door hinge tube movably connecting the front door side frame and the side door side frames, a first upper pin shaft passing through the front door hinge tube and the side door hinge tube, a first lower pin shaft passing through the front door hinge tube and the side door hinge tube, a second upper pin shaft passing through the side door hinge tube and the rear door hinge tube, and a second lower pin shaft passing through the side door hinge tube and the rear door hinge tube;

[0007] The front door hinge tube, the side door hinge tube and the rear door hinge tube are riveted and welded to the outer sides of the front door side frame, the side door side frame and the rear door side frame respectively;

[0008] The outer side surfaces of the front door side frame, the rear door side frame and the side door side frame and the corresponding positions of the adjacent hinge tubes are set to a flat structure, and the angle occupied by the flat structure on the circumferential surface of the cross-section of the front door side frame and the side door side frame is 55° to 65°; after the front door, the side door and the rear door of the wire mesh turnover box are folded with each other, there is a gap between the hinge tube and the adjacent side frame.

[0009] Preferably, the flat structure occupies an angle of 60° on the cross section of the connecting pipe.

[0010] Preferably, the first upper pin shaft, the first lower pin shaft, the second upper pin shaft, and the second lower pin shaft are all pins with open lower ends, and the surfaces of the pins are polished.

[0011] As a further improvement, the front door, the two side doors and the lower portion of the rear door are each provided with two casters.

[0012] Preferably, the caster is a universal wheel.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This frame connection structure effectively solves the problem of folding jams in WP-type wire mesh turnover boxes after assembly by flattening the side frames at designated locations. This improves assembly efficiency, reduces product defect rates, eliminates jams that occur during folding after assembly, and saves the cost of repeated assembly. This product saves space when stacking fence-type products. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is further explained and illustrated below with reference to the accompanying drawings and embodiments. It should be noted that all other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0022] Example: See Figure 1-Figure 5 A frame connection structure for a storage fence, the storage fence includes a front door, two symmetrical side doors and a rear door; the frame connection structure is used to fold the front door and side doors of the storage fence to the rear door and then fold them for use when stacking and storing.

[0023] The frame connection structure is used for stacking and storing the folded wire mesh turnover boxes; the front door 8, side door 6 or 7 and rear door 3 are respectively composed of a wire mesh portion and an upper frame, side frame and lower frame connected to the wire mesh portion on all sides;

[0024] The frame connection structure includes a front door side frame 401, a rear door side frame 403 and a bilaterally symmetrical side door side frame 402, a front door hinge tube 1 movably connecting the front door side frame 401 and the side door side frame 402, a side door hinge tube 2 movably connecting the front door side frame 401 and the side door side frame 402, a first upper pin shaft 501 passing through the front door hinge tube and the side door hinge tube, a first lower pin shaft 502 passing through the front door hinge tube and the side door hinge tube, a second upper pin shaft 503 passing through the side door hinge tube 2 and the rear door hinge tube, and a second lower pin shaft 504 passing through the side door hinge tube 2 and the rear door hinge tube; the front door hinge tube 1, the side door hinge tube 2 and the rear door hinge tube are riveted to the outer sides of the front door side frame 401, the side door side frame 402 and the rear door side frame 403 respectively;

[0025] The outer side surfaces of the front door side frame 401, the rear door side frame 403 and the side door side frame 402 and the corresponding positions of the adjacent hinge tubes are set to form a flat structure 9, and the angle occupied by the flat structure 9 on the circumferential surface of the cross-section of the front door side frame 401 and the side door side frame 402 is 55° to 65°; after the front door, side door and rear door of the wire mesh turnover box are folded with each other, there is a gap between the hinge tube and the adjacent side frames.

[0026] Generally speaking, each door of the storage fence has two upper and lower flattening positions on both sides, and the specific positions are relative to the positions of the corresponding hinge tubes.

[0027] Operation: First, use the split pin as a pivot to connect the aligned front door connecting tube 1 and side door connecting tube 2. Then, hammer the pin into a split shape to complete the hinge tube positioning. Next, flatten the corresponding hinge tubes on the front, side, and rear door side frames where they meet the hinge tubes. Afterwards, polish and paint. Once completed, the front and rear doors can be smoothly folded onto the rear door, saving storage space for transportation and other scenarios without deforming the side frames of the storage enclosure.
