Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of folding basket devices, specifically a durable and pressure-resistant plastic folding basket. Background Technology
[0002] In modern logistics, warehousing, and daily life, folding plastic crates are widely used due to their ease of storage and space-saving features. When not in use, folding plastic crates can be folded up, greatly reducing the space they occupy and facilitating storage and transportation; when in use, they can be quickly unfolded and put into operation, offering extremely high convenience.
[0003] However, traditional folding plastic baskets have certain structural design flaws, resulting in poor performance in terms of durability and compressive strength. In terms of durability, during frequent folding and unfolding, the connections between components in traditional folding baskets are prone to loosening and wear, gradually reducing the overall structural stability of the basket and shortening its lifespan. Regarding compressive strength, traditional folding baskets typically lack effective support structures, making them prone to deformation or self-folding under pressure, thus failing to meet the requirements of usage scenarios with high load-bearing capacity and stability. Utility Model Content
[0004] (I) Technical Issues
[0005] This utility model provides a durable and pressure-resistant plastic folding basket, which solves the problems of loose and worn joints, insufficient pressure resistance, and easy folding under pressure in traditional folding baskets during frequent use.
[0006] (II) Technical Content
[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a durable and pressure-resistant plastic folding basket, including a base plate, an upper frame, and an Oxford cloth bag fixedly disposed between the base plate and the upper frame. A height adjustment mechanism is fixedly connected between the four corners of the base plate and the upper frame. A cross support mechanism is connected between the front and rear sides of the base plate and the upper frame. The cross support mechanism includes two support rods pivotally connected by a pin. The two support rods are arranged crosswise and their two ends are slidably connected to the base plate and the upper frame, respectively. A limiting guide rail assembly for limiting the cross rotation of the two support rods is fixedly provided at the front and rear ends of the upper top of the base plate.
[0008] Furthermore, the limiting guide rail assembly includes a vertical plate fixedly mounted on the upper surface of the base plate, a sliding groove provided on the inner side of the vertical plate, a slider fixedly mounted on the outer end of the pin shaft, the slider being slidably connected to the sliding groove, and a plurality of positioning holes provided on the side of the vertical plate, with positioning bolts passing through the positioning holes, the positioning bolts extending into the positioning holes and threadedly connected to the threaded holes on the side of the slider.
[0009] Furthermore, the height adjustment mechanism includes insertion cavities fixed at the four corners of the upper surface of the base plate, and guide rods fixed at the four corners of the bottom of the upper frame. The guide rods are movably connected to the insertion cavities, and the side of the guide rods is provided with several threaded holes. The upper end of the side of the insertion cavity is threaded with an adjusting bolt that matches the threaded holes.
[0010] Furthermore, handles are fixedly provided on both the left and right sides of the upper frame, and rubber anti-slip pads are fixedly provided at the four corners of the bottom of the base plate.
[0011] Furthermore, guide frames for sliding at the ends of the support rods are fixedly provided on opposite sides of the base plate and the upper frame.
[0012] (III) Technical Effects
[0013] Compared with the prior art, the advantages of this utility model are as follows: the cooperation between the guide rod and the insertion cavity in the height adjustment mechanism, combined with the fixing of the adjusting bolt, strengthens the connection strength between the bottom plate and the upper frame. The traditional flip folding is changed to up-and-down folding, which reduces the wear and loosening between parts when folding and unfolding, and significantly improves the durability of the folding basket. The cross support mechanism is formed by the cross arrangement of support rods pivotally connected by pins, combined with the positioning constraint of the limit guide rail assembly, forming a stable support structure when loading heavy objects, effectively resisting external pressure, preventing the basket from deforming, and avoiding self-folding under pressure, which greatly enhances the pressure resistance and support performance.

[0023] Combined with appendix Figure 1 To be continued Figure 5 A durable and pressure-resistant plastic folding basket includes a base plate 1, an upper frame 2, and an Oxford cloth bag 3 fixed between the base plate 1 and the upper frame 2. A height adjustment mechanism is fixedly connected between the four corners of the base plate 1 and the upper frame 2. A cross support mechanism is connected between the front and rear sides of the base plate 1 and the upper frame 2. The cross support mechanism includes two support rods 5 pivotally connected by a pin 4. The two support rods 5 are arranged crosswise and their ends are slidably connected to the base plate 1 and the upper frame 2, respectively. A limiting guide rail assembly for restricting the cross rotation of the two support rods 5 is fixedly provided at the front and rear ends of the upper end of the base plate 1. A handle 15 is fixedly provided on the left and right sides of the upper end of the upper frame 2. A rubber anti-slip pad 16 is fixedly provided at the four corners of the bottom of the base plate 1. A guide frame 17 for sliding of the ends of the support rods 5 is fixedly provided on the opposite sides of the base plate 1 and the upper frame 2.
[0024] In this embodiment, as a preferred technical solution, the limiting guide rail assembly includes a vertical plate 6 fixedly disposed on the upper end face of the base plate 1. The inner side of the vertical plate 6 is provided with a sliding groove 7. The outer end of the pin 4 is fixedly provided with a slider 8. The slider 8 is slidably connected to the sliding groove 7. The side of the vertical plate 6 is provided with a plurality of positioning holes 9. Positioning bolts 10 are inserted into the positioning holes 9. The positioning bolts 10 extend into the positioning holes 9 and are threadedly connected to the threaded holes on the side of the slider 8.
[0025] In this embodiment, as a preferred technical solution, the height adjustment mechanism includes an insertion cavity 11 fixedly disposed at the four corners of the upper end face of the base plate 1, and a guide rod 12 fixedly disposed at the four corners of the bottom of the upper frame 2. The guide rod 12 is inserted into the insertion cavity 11. The side of the guide rod 12 is provided with a plurality of threaded holes 13. The upper end of the side of the insertion cavity 11 is threadedly connected with an adjustment bolt 14 that matches the threaded holes 13.
[0026] The working principle of this utility model is as follows: When unfolded for use, by tightening the adjusting bolt 14 at the upper end of the side of the insertion cavity 11 and threadedly connecting it to the threaded hole 13 on the side of the guide rod 12, the distance between the upper frame 2 and the base plate 1 can be adjusted according to actual needs, thereby adjusting the height of the folding basket. During the unfolding process, the end of the support rod 5 slides along the guide frame 17 on the base plate 1 and the upper frame 2. At the same time, the slider 8 moves upward along the slide groove 7. After the height is determined, the positioning bolt 10 passes through the positioning hole 9 and is threadedly connected to the slider 8, thereby fixing the position of the slider 8, thus folding the two... The support rods 5 are fixed in place, providing support and resistance to pressure, preventing the basket from deforming and folding under pressure. The Oxford cloth bag 3 is used for loading items and folding. The rubber anti-slip pad 16 on the bottom of the base plate 1 increases stability when placed. The handle 15 on the upper frame 2 makes it easy to carry. When not in use, loosen the adjusting bolt 14 and the positioning bolt 10, insert the guide rod 12 deep into the insertion cavity 11, and at the same time, the two support rods 5 slide along the guide frame 17 and cross-fold, which can realize the reduction of the height of the folded basket and save space. During the folding process, the Oxford cloth bag can adapt to deformation.
