[0022] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and facilitating its implementation.

[0023] It should be noted that, in the following embodiments, the “first” and “second” mentioned do not represent an absolute distinction in structure and / or function, nor do they represent a sequential order of execution, but are merely for the convenience of description.

[0024] like Figures 1 to 3As shown, the present invention provides an extendable material rack, including a material rack frame 1 and a first material box 2 and a second material box 3 arranged on the material rack frame 1, the second material boxes 3 are arranged on both sides of the first material box 2, the second material box 3 is movably arranged on the material rack frame 1, the second material box 3 is arranged to be movable toward the outside of the material rack frame 1, and the second material boxes 3 on both sides of the first material box 2 move in opposite directions.

[0025] Specifically, if Figure 1 and Figure 2 As shown, the rack frame 1 is a rectangular frame structure with a hollow interior, and the first material box 2 is fixedly arranged on the rack frame 1. The second material box 3 is arranged to be switchable between a storage state and an extended state. When the second material box 3 is in the storage state, the second material box 3 is completely located in the inner cavity of the rack frame 1. At this time, the first material box 2 and the second material box 3 are on the same straight line parallel to the first direction, and the first direction is a horizontal direction; when the second material box 3 is in the extended state, one end of the second material box 3 is located in the inner cavity of the rack frame 1, and the other end of the second material box 3 is located outside the rack frame 1. Openings for the second material box 3 to pass through are arranged at both ends of the rack frame 1, and the ends of the rack frame 1 are in an open state to ensure that the second material box 3 will not be obstructed during the extension and retraction process. When the second material box 3 switches from the storage state to the extended state, the moving direction of the second material box 3 is parallel to the second direction, and the second direction is a horizontal direction and the second direction is perpendicular to the first direction. When the second material box 3 switches from the storage state to the extended state, its moving direction is parallel to the second direction (horizontal direction and perpendicular to the first direction). This design makes the extension and retraction of the second material box 3 more stable and smooth, and also avoids interference with the rack frame 1 or other components.

[0026] like Figure 1 and Figure 2 As shown, a plurality of storage compartments are arranged on the first material box 2, and the storage compartments are used to accommodate items to be transferred. All storage compartments on the first material box 2 are distributed in an n*m matrix. This distribution method not only maximizes the use of space, but also makes the storage and retrieval of items more orderly and efficient.

[0027] like Figure 1 and Figure 2 As shown, a plurality of storage compartments are provided on the second material box 3, and the storage compartments are used to accommodate the items to be transferred. All the storage compartments on the second material box 3 are distributed in an n*m matrix, which not only maximizes the use of space, but also makes the storage and removal of items more orderly and efficient. When the second material box 3 is in the extended state, the storage compartments are also located outside the material rack frame 1, which is convenient for taking and placing items in the storage compartments.

[0028] like Figure 1 and Figure 2As shown, two second material boxes 3 are provided, the first material box 2 is located between the two second material boxes 3, a slide rail 4 is provided on the material rack frame 1, and the second material box 3 is slidably connected to the slide rail 4, ensuring that the second material box 3 can move steadily and smoothly during the extension and retraction process, and the length direction of the slide rail 4 is parallel to the second direction. In the process of the two second material boxes 3 switching from the storage state to the extension state, the movement directions of the two second material boxes 3 are opposite, and the two second material boxes 3 respectively pass through the openings at both ends of the material rack frame 1 and extend toward the outside of the material rack frame 1. This design avoids interference or collision between the two second material boxes 3 during the extension process, and ensures the stability and reliability of the material rack frame 1. At the same time, it also provides a larger operating space, which is convenient for operators to take and put items in the storage grid, which can save time and improve work efficiency.

[0029] like Figures 1 to 3 As shown, a support mechanism is provided on the second material box 3, and the support mechanism is arranged to be height-adjustable. After the second material box 3 is moved outward toward the outside of the material rack frame 1, the support mechanism located outside the material rack frame 1 provides support for the second material box 3, ensuring the stability and safety of the second material box 3 in the extended state, making the second material box 3 more stable when carrying items. The support mechanism is cleverly designed to be height-adjustable, which means that the operator can easily adjust the height of the support mechanism according to actual needs to adapt to the state switching of the second material box 3. When the second material box 3 is in the storage state, the height of the support mechanism is the highest; when the second material box 3 is in the extended state, the height of the support mechanism is the lowest.

[0030] like Figure 3 As shown, in this embodiment, the support mechanism includes a sliding seat 5 and a caster 7 and a locking pin 6 arranged on the sliding seat 5. The second material box 3 is provided with a locking hole 8 for inserting the locking pin 6. At least two locking holes 8 are provided. The locking holes 8 are arranged in sequence along the vertical direction. The locking pin 6 is inserted into the locking hole 8, so that the height of the support mechanism can be fixed. The caster 7 is used to contact the ground where the material rack is located. The setting of the caster 7 can provide support for the second material box 3 while allowing the second material box 3 to move easily when the state is switched. The second material box 3 is provided with a slide groove, which is vertically arranged. The sliding seat 5 is inserted into the slide groove, and the locking hole 8 is located in the slide groove. Two slide grooves are provided, and the two slide grooves are on the same straight line parallel to the first direction. The two ends of the sliding seat 5 are respectively inserted into the two slide grooves. The slide groove guides the sliding seat 5 so that the sliding seat 5 can slide up and down in the slide groove, thereby realizing the adjustment of the height of the support mechanism. The number of the slide grooves is set to two. This design not only enhances the stability of the sliding seat 5, but also makes the support mechanism more stable and smooth when adjusting the height. The operator can slide the sliding seat 5 up and down and insert the locking pin 6 into the locking hole 8 at a suitable height to fix the height of the support mechanism. This design is not only easy to operate, but also ensures the stability and safety of the support mechanism at different heights.

[0031] like Figure 3 As shown, two locking pins 6 are provided on the sliding seat 5, and the two locking pins 6 are on the same straight line parallel to the first direction, and the two locking pins 6 are respectively used to insert into the two locking holes 8 to ensure reliable locking. When the second material box 3 needs to be extended or stored, the operator can adjust the position of the sliding seat 5 in the slide groove according to actual needs, and then insert the two locking pins 6 into the locking holes 8 of the corresponding heights respectively. Since the two locking pins 6 are on the same straight line and are firmly inserted into the locking holes 8, the support mechanism is very stable after the height is fixed, and it is not easy to shake or tilt. In addition, the design of the two locking pins 6 also increases the redundancy of locking. Even if one of the locking pins 6 fails for some reason (such as wear, looseness, etc.), the other locking pin 6 can still maintain the stability of the support mechanism, thereby avoiding the safety hazard caused by the failure of a single locking point. This design of arranging two locking pins 6 on the sliding seat 5 not only enhances the stability of the support mechanism and the reliability of locking, but also improves the overall safety and functionality of the rack frame 1. This design allows operators to feel more assured when operating the rack frame 1, and also provides a more stable and safe supporting environment for the transfer of items.

[0032] The material rack of the above structure has material boxes divided into multiple layers at the front and rear. When taking out parts, you only need to pull the front and rear material boxes apart and put down the casters 7 to complete the taking out. After taking out the parts, you only need to push the material box back into the material rack and lift the casters 7 to fix the cloth bag. The operation is simple, the number of material racks that can be accommodated is increased, and the transportation cost is reduced.
