Abstract
Description
Technical Field
[0001] This utility model relates to the field of material cabinets, specifically to a material cabinet that prevents drawer boxes from exceeding their limit positions. Background Technology
[0002] Material cabinets are tool cabinets used to store materials in a factory; heavy materials are often placed inside them.
[0003] Because the drawers of the material cabinet are quite heavy after materials are placed inside, operators may pull them too hard when pulling them, causing them to move beyond their limit position and damaging the material cabinet. There is a technical problem that operators may sometimes pull the drawers beyond their limit position, so there is an urgent need to design a material cabinet that prevents the drawers from moving beyond their limit position.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content
[0005] The purpose of this invention is to provide a material cabinet that prevents drawer boxes from exceeding their limit positions, thus solving the above problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A material cabinet that prevents drawer boxes from exceeding their limit positions includes:
[0008] Drawer box;
[0009] A frame comprising a base and a top cover interconnected to form a holding cavity for holding a drawer box, the drawer box being slidably connected to the base, and the top cover being located directly above the base to allow the drawer box to be pulled out of and pushed into the holding cavity;
[0010] An auxiliary mechanism, one end of which is connected to the end of the drawer box and the other end is located on the base away from the drawer box, is used to adjust the force when the drawer box is pulled out and pushed into the holding cavity.

[0017] In one alternative embodiment, the mounting component is made of iron;
[0018] The adsorption element is an electromagnet.
[0019] In one alternative embodiment, the mounting element is specifically plate-shaped;
[0020] The mounting component and the adsorption component are in a straight line.
[0021] In one optional embodiment, a limiting ring is provided on the side of the mounting member facing the adsorption member;

[0042] refer to Figures 1 to 2 At least one embodiment provides a material cabinet to prevent the drawer box from exceeding its limit position, comprising: a drawer box 1 for directly placing materials; a frame 2 including a base 21 and a top cover 22 connected to each other to form a holding cavity for holding the drawer box 1, the drawer box 1 being slidably connected to the base 21, and the top cover 22 being located directly above the base 21 to make the drawer box 1 suitable for being pulled out of and pushed into the holding cavity, i.e., to facilitate the removal of materials and the storage of materials after they are placed in the drawer box 1; an auxiliary mechanism 3, one end of which is connected to the end of the drawer box 1, and the other end of which is located on the base 21 away from the drawer box 1, for adjusting the force when the drawer box 1 is pulled out and pushed into the holding cavity, i.e., providing a pushing force when the drawer box 1 is pulled to reduce the force required by the operator to pull, and restricting the drawer box 1 from being pulled further when it is close to the limit position; providing a suction force when the drawer box 1 is pushed in to reduce the pushing force required by the operator; both the drawer box 1 and the frame 2 are electrically connected to an external control system for controlling their operation and stopping, as well as transmitting signals.
[0043] In some embodiments, the auxiliary mechanism 3 includes a mounting member 31, an elastic member 32, and an adsorption member 33; the mounting member 31 is fixedly disposed at the end of the drawer box 1; the adsorption member 33 is disposed on the base 21 away from the drawer box 1; the mounting member 31 is connected to the adsorption member 33 through the elastic member 32; when the drawer box 1 is pulled, a pushing force is provided to reduce the force required by the operator to pull, while the drawer box 1 is restricted from being pulled further when it is close to the limit position; when the drawer box 1 is pushed in, a suction force is provided to reduce the pushing force required by the operator.
[0044] In some embodiments, the mounting member 31 is made of a ferromagnetic material; the adsorption member 33 is a magnet, used to ensure that a magnetic attraction force can be generated between the two.
[0045] In some embodiments, the mounting component 31 is made of iron; the adsorption component 33 is an electromagnet, used to facilitate the control of the generation and disappearance of magnetic attraction.
[0046] In some embodiments, the mounting member 31 is specifically plate-shaped; the mounting member 31 and the adsorption member 33 are in a straight line.
[0047] In some embodiments, the mounting member 31 has a limiting ring on the surface facing the adsorption member 33; the adsorption member 33 has a limiting ring on the surface facing the mounting member 31; and both ends of the elastic member 32 are located within the two limiting rings.
[0048] In some embodiments, the elastic element 32 is a spring; the middle part of the elastic element 32 is separated from the mounting element 31 and the adsorption element 33.
[0049] In some embodiments, the drawer box 1 includes a top 11; the top 11 is provided with a sensor 12 with its sensing surface facing the top cover 22, for detecting changes in the relative position between the drawer box 1 and the top cover 22.
[0050] In some embodiments, the sensor 12 is a proximity switch; the sensor 12 is arranged in a linear array on the top 11.
[0051] Working principle: When the drawer cabinet is first used: Drawer box 1 is located directly below the top cover 22. The external control system stops supplying power to the suction element 33. At this time, there is no magnetism between the suction element 33 and the drawer box 1, and the elastic element 32 is compressed. When it is necessary to pull out the drawer box 1, the operator manually pulls the drawer box 1, allowing it to slide on the base 21. Due to the pushing force of the elastic element 32, the operator can easily pull the drawer box 1. During this process, the sensors 12 on the top 11 move away from below the top cover 22 in sequence and can no longer sense information from the top cover 22. When the drawer box 1 reaches its limit position, it cannot be pulled further under the pull of the elastic element 32. At the same time, when all sensors 12 supply power to the external system, the suction element 33 starts to work, generating partial suction force on the drawer box 1, making it... Drawer box 1 cannot be pulled further. At this time, the operator can easily put materials into drawer box 1. When it is necessary to push drawer box 1 under the cover 22, due to the adsorption force generated by the suction member 33 on drawer box 1 and the pulling force of the elastic member 32, the operator can push drawer box 1 to move under the cover 22 with very little effort. Then, multiple sensors 12 on the top 11 will detect the signal of the cover 22 in sequence. As drawer box 1 moves under the cover 22, the adsorption force generated by the suction member 33 continues to increase, thereby ensuring that the operator can easily push the entire drawer box 1 under the cover 22 until all sensors 12 can sense the signal position of the cover 22. At this time, the pushing of drawer box 1 is completed, the elastic member 32 is compressed, and the suction member 33 stops generating magnetic attraction.
