Description

Technical Field

[0001] The present invention belongs to the technical field of logistics transportation equipment, and in particular relates to a compatible locking and folding limiting mechanism. Background Art

[0002] As the degree of concentration in various industries continues to increase, the logistics industry has developed rapidly, and the equipment used to load goods during logistics transportation is collectively referred to as "carriers." There are many types of logistics carriers. Although disposable packaging containers such as cartons and wooden boxes are light in weight and easy to transfer, they are not strong enough to protect the equipment and cannot be recycled. Metal packaging containers, although they can protect the equipment, are heavy and prone to rust after repeated use. Currently, more and more industries are beginning to use small unitized logistics carriers such as plastic pallets and panel boxes. They are not only light in weight and strong in strength, but also durable and wear-resistant, not easy to deform, and suitable for long-term repeated use. The existing panel boxes are square in shape, and their volume remains unchanged when fully loaded and empty. Empty panel boxes cannot be compressed and stacked to save space, and the vehicle loading rate of empty panel boxes is very low. Summary of the Invention

[0003] In response to the above problems and technical requirements, the present invention provides a compatible locking folding limit mechanism, which can be folded and compressed to save space and improve the loading rate of the empty panel box.

[0004] The foldable frame is configured to be folded 90 degrees in a vertical direction and has a foldable frame, wherein the foldable frame is configured to be folded 90 degrees in a vertical direction and has a foldable frame. When all the slide bars slide to the upper transverse groove, they can support the folding panels, making it difficult for them to collapse inward, thereby protecting the utensils in the basket. When all the slide bars slide to the lower transverse groove, the restriction on the folding panels is released, so that the folding panels can be folded inward, saving the volume of the basket and facilitating the transportation of empty baskets.

[0005] Furthermore, the interior of the housing is provided with two sets of sliding bar mechanisms staggered horizontally and vertically. The two sets of sliding bar mechanisms have identical structures, with the upper transverse grooves in the two sets of sliding bar mechanisms staggered vertically, and the lower transverse grooves in the two sets of sliding bar mechanisms also staggered vertically. The two staggered sliding bar mechanisms, acting separately on the two sets of side walls, provide a better support and position-limiting effect for the housing.

[0006] Furthermore, the upper transverse groove, lower transverse groove, and vertical groove are all provided through the folding panel or fixed side panel, and the ends of the slide rod extend outward through the grooves. The ends of the slide rod can be clamped on the outer wall of the basket to lock the slide rod. When the slide rod is positioned in the upper transverse groove and the lower transverse groove, it is locked by the lock, which can prevent the slide rod from sliding back and forth and make the slide rod more stable.

[0007] Furthermore, the sliding rod includes a rod body, a rod head and a lock buckle. The rod head is fixedly arranged at the end of the rod body. The diameter of the rod head is smaller than the width of the slot, and the width of the slot is smaller than the diameter of the rod body. The rod head extends out of the slot and is connected to the lock buckle. By rotating the lock buckle, the rod body can be pulled and locked.

[0008] Furthermore, the lock includes a rotating shaft and a wrench, the wrench is rotatably connected to both ends of the rotating shaft, the outer contour of the wrench is curved, a through hole is provided in the middle of the rotating shaft, and the rod head is inserted into the through hole and fixedly connected to the rotating shaft vertically.

[0009] Furthermore, when the wrench rotates around the rotating shaft, the outer profile of the wrench clamps or loosens the outer side surface of the basket.

[0010] Furthermore, the length of the upper transverse groove is consistent with the length of the inner wall of the folding panel, and the lower transverse groove is located in the middle of the fixed side panel, and the upper transverse groove is longer than the lower transverse groove. When the sliding rods are located in the upper transverse groove, multiple sliding rods are evenly distributed along the entire length of the folding panel to achieve the best support effect. Therefore, the length of the upper transverse groove is the same as the folding panel. When the folding panel is folded and stowed, no sliding rod support is required. Multiple sliding rods are close together and stowed in the lower transverse groove, so the length of the lower transverse groove is shorter.

[0011] Furthermore, the outer sidewall of the housing is provided with transverse and vertical reinforcing ribs, which provide the wide sidewall with greater mechanical strength and are less susceptible to damage.

[0012] Furthermore, the folding panel and the fixed side panel are movably connected via a concave-convex interlaced structure, and the folding panel and the fixed side panel are detachably connected.

[0013] Furthermore, when the folding panels are folded inwards by 90 degrees, the covering width thereof does not exceed 1 / 2 of the width of the basket, and after the two folding panels are folded inwards, an opening and closing gap is formed in the middle. The opening and closing gap facilitates the operator to open and close the basket.

[0014] The beneficial effects of the present invention are as follows: the panel basket of the present invention is connected by a combination of a folding panel and a bottom basket, so that the upper panel of the basket can be folded inward, which greatly compresses the volume of the basket in an empty state, is beneficial to the stacking arrangement of empty baskets, and improves the transportation loading rate; two sets of sliding rod mechanisms are arranged in the basket, and the sliding rods can slide up and down. In a fully loaded state, the sliding rods are evenly arranged in the upper transverse grooves, and can support the folding panels after being locked to protect the utensils in the basket. In an empty state, the sliding rods are retracted in the lower transverse grooves, removing the restrictions on the folding panels, allowing them to fold freely and fold inward, which is convenient for the transfer and stacking of empty baskets; the folding panels and the fixed side panels are easy to assemble and disassemble, which is convenient for maintenance, management and storage, and can be recycled many times.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-7 The figure shows a folding panel basket with a locking and limiting mechanism of the present invention, including a basket body 1 and a slide rod mechanism 4. The basket body 1 includes a bottom basket 2 and a folding panel 3. The bottom basket 2 includes a bottom surface 21 and fixed side panels 22. Four fixed side panels 22 are vertically connected to the four sides of the bottom surface 21. The upper edge of each fixed side panel 22 is movably connected to a folding panel 3, and the folding panel 3 can be folded inward 90°.

[0025] The slide bar mechanism 4 is mounted inside the basket 1. The slide bar mechanism 4 includes an upper transverse groove 41, a lower transverse groove 42, a vertical groove 43, and a plurality of slide bars 5. The two upper transverse grooves 41 are correspondingly arranged on the inner wall of a group of folding panels 3, and the two lower transverse grooves 42 are correspondingly arranged on the inner wall of a group of fixed side panels 22. The upper transverse groove 41 is parallel to the lower transverse groove 42, and the two ends of the vertical groove 43 are connected to the upper transverse groove 41 and the lower transverse groove 42 respectively. The slide bar 5 can slide freely along the upper transverse groove 41 or the lower transverse groove 42, and the slide bar 5 switches its position between the upper transverse groove 41 and the lower transverse groove 42 through the vertical groove 43. In a preferred embodiment, two groups of slide bar mechanisms 4 are arranged inside the basket 1 in a horizontal and vertical staggered manner. The two groups of slide bar mechanisms 4 have the same structure. The upper transverse grooves 41 in the two groups of slide bar mechanisms 4 are staggered vertically, and the lower transverse grooves 42 are also staggered vertically.

[0026] The length of the upper transverse groove 41 is consistent with the length of the inner wall of the folding panel 3, and the lower transverse groove 42 is set in the middle of the fixed side panel 22. The length of the upper transverse groove 41 is greater than that of the lower transverse groove 42. When the slide rods 5 are located in the upper transverse groove 41, multiple slide rods 5 are evenly distributed along the entire length of the folding panel 3 to achieve the best support effect. Therefore, the length of the upper transverse groove 41 is the same as the folding panel 3. When the folding panel 3 is folded and retracted, the slide rods 5 are not needed for support. Multiple slide rods 5 are close to and retracted in the lower transverse groove 42, so the length of the lower transverse groove 42 is shorter. When all the slide rods 5 slide to the upper transverse groove 41, they can support the folding panel 3, preventing it from collapsing inward and protecting the utensils in the basket. When all the slide rods 5 slide to the lower transverse groove 42, the folding panel 3 can be folded inward, saving the volume of the basket and facilitating the transportation of the empty basket.

[0027] The outer wall of the housing is provided with transverse and vertical reinforcing ribs 11. The folding panels 3 and the fixed side panels 22 are movably connected via a concave-convex interlaced structure 32. The folding panels 3 and the fixed side panels 22 are detachably connected. Clips 31 are provided on both sides of the folding panels 3. The four folding panels 3 are detachably connected by the clips 31 when in the vertical position.

[0028] The upper transverse groove 41, the lower transverse groove 42, and the vertical groove 43 are all set through the folding panel 3 or the fixed side panel 22. The two ends of the slide rod 5 extend outward through the notch. The two ends of the slide rod 5 can clamp the outer wall of the basket to lock the slide rod 5. The slide rod 5 includes a rod body 51, a rod head 52, and a lock 53. The rod head 52 is fixedly set at the end of the rod body 51. The diameter of the rod head 52 is smaller than the width of the notch, and the width of the notch is smaller than the diameter of the rod body 51. The rod head 52 extends out of the notch and is connected to the lock 53. By rotating the lock 53, the rod body 51 can be pulled and locked. The lock 53 includes a rotating shaft 531 and a wrench 533. The wrench 533 is rotatably connected to the two ends of the rotating shaft 531. The outer profile of the wrench 533 is curved. A through hole 532 is provided in the middle of the rotating shaft 531. The rod head 52 is inserted into the through hole 532 and is vertically fixedly connected to the rotating shaft 531. When the wrench 533 rotates around the rotating shaft 531, the outer profile of the wrench 533 clamps or loosens the outer side of the frame. When the slide bar 5 determines its resting position in the upper transverse groove 41 and the lower transverse groove 42, it is locked by the lock 53 to prevent the slide bar 5 from sliding back and forth, making the slide bar 5 more stable.

[0029] When the folding panels 3 are folded inwards by 90°, the covering width thereof does not exceed 1 / 2 of the width of the basket 1 . After the two folding panels 3 are folded inwards, an opening and closing gap 6 is formed in the middle. The opening and closing gap 6 facilitates the operator to open and close the basket 1 .
