Description

Technical Field

[0001] The utility model relates to the technical field of cabinet structure, in particular to a detachable connector and a cabinet. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the utility model recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.

[0003] At present, various cabinets, including intelligent distribution for behavioral management, clothing receiving and sending, lockers, especially for medical treatment cabinets, have always been integral steel welded structures, large in size and weight. The corners inside the whole cabinet are not easy to adhere to epoxy resin powder due to air rebound, and the resistance welding of the whole structure makes it difficult to achieve full coverage of powder in the gaps between the plates. This will cause a large difference in the quality of the spraying inside and outside the cabinet, and even some corners are not covered with powder at all. This will cause durability, rust prevention and other quality problems of the steel treatment cabinet. In addition, the use of an integral welded structure will also cause long-distance transportation costs to be too high, and it cannot be produced in a modular manner, installation and disassembly are troublesome, maintenance is inconvenient, and manufacturing costs are high. The production of components will effectively solve the current transportation and quality problems. Utility Model Content

[0026] The utility model aims to solve the problems that the existing cabinets cannot be produced in modularized form, are troublesome to install and disassemble, have high transportation costs, are inconvenient to repair, have high manufacturing costs, are not easy to adhere to epoxy resin powder in the corners due to air rebound, and have poor spraying quality. The components are made into standardized parts to achieve interchangeability, and can be combined into different lengths and sizes according to the size and length of the hospital space. The components can be stored and shipped quickly when needed, and the cabinet can be easily installed and fully disassembled. The following is an explanation through specific embodiments.

[0027] Optionally, as an embodiment, a detachable connector, such as Figure 1 As shown, it includes a first connecting member 1, a second connecting member 2 and a driving member, the first connecting member 1 is provided with a first groove 3, the second connecting member 2 is provided with a second groove 4, a locking block is provided in the first groove 3, and a locking portion for clamping the locking block is provided in the second groove 4, and the locking block can move in the first groove 3 and the second groove 4 to achieve the connection and disassembly of the above-mentioned connecting members. Optionally, the locking block and the locking portion can be designed in various ways that can be locked, such as a circular groove in the locking part, and the locking block is an open elastic lock head 9. When pressed into the groove, the opening is first pressed and then opened to achieve clamping. When pulled outward, the opening of the lock head 9 is pressed again, and reopened after being separated from the groove to achieve disassembly. The lock head 9 can also be designed as a smooth ellipsoidal sphere, and the connection or disassembly is achieved by squeezing the ellipsoidal sphere when pressed in or pulled out.

[0028] In some embodiments, the locking block is an eccentric block 5, such as Figure 2 As shown, the eccentric block 5 can move along an arc in the first groove 3 with the center of the operating hole 6 as the center of a circle, and the arc covers the opening of the first groove 3. A locking head 9 is provided at one end of the eccentric block 5 close to the second groove 4. The locking head 9 is a protrusion protruding from the eccentric block 5. The boundary line between the locking head 9 and the eccentric block 5 forms an eccentric spiral curve. The locking portion in the second groove 4 is a protrusion matching the eccentric spiral curve of the locking head 9. When the eccentric block 5 moves to the area of ​​the second groove 4 passing through the locking portion, it is clamped with the locking portion to achieve the connection between the first connecting member 1 and the second connecting member 2. When the eccentric block 5 leaves the area of ​​the locking portion, the first connecting member 1 and the second connecting member 2 are disassembled. In terms of material, a metal structure can be used as the zinc alloy eccentric block 5, and the first connector 1 and the second connector 2 are nylon parts. In specific implementation, the driving part is inserted into the operating hole 6, and the eccentric block 5 is driven to rotate 90 degrees to hook the nylon gap connected to another steel plate, thereby achieving a firm connection, which is collectively referred to as a three-in-one connector for steel plates. When it needs to be removed, it only needs to rotate the zinc alloy eccentric connector 90 degrees in the opposite direction to achieve disassembly, thereby achieving the arbitrary disassembly and assembly and convenient transportation of the medical treatment cabinet. When the eccentric block 5 is in use, the front end opening can also be inserted into the nylon gap. During the subsequent rotation process, since the eccentric block 5 is an eccentric curve, the nylon block will be gradually tightened, thereby achieving the purpose of connection. Disassembly can be achieved when rotating in the opposite direction.

[0029] Specifically, in terms of the driving of the locking block, in some embodiments, the side wall of the first connecting member 1 is provided with a through hole intersecting the first groove 3, and the locking block is provided with a non-circular operating hole 6 in the area of ​​the cross section of the through hole, and the shape of the operating hole 6 can be polygonal, and the hexagonal wrench hole is selected in this embodiment. The driving member has an operating end matching the operating hole 6, and the operating end is inserted into the driving hole and rotates to drive the locking block to move in the first groove 3 and the second groove 4. In specific implementation, the driving member is a stainless steel rod matching the hexagonal wrench hole, and the cross section of the end is hexagonal.

[0030] In order to further enhance the connection strength and reliability, in some embodiments, the first connecting member 1 is further provided with a second locking block 7, and the second connecting member 2 is further provided with a third groove 10 matching the second locking block 7. When the eccentric block 5 is clamped with the locking portion, the second locking block 7 cooperates with the third groove 10 to achieve further locking. Optionally, the second locking block 7 is a rectangular parallelepiped, which is arranged at the upper and lower ends of the first groove 3, and the third groove 10 is a square hole matching the shape of the second locking block 7, such as Figure 3 shown.

[0031] In some embodiments, the first connector 1 and the second connector 2 are respectively fixed to the parts to be connected by screws 8. Specifically, a circular groove is washed out at both ends of the first connector 1 and the second connector 2, and a screw hole 11 is punched in the circular groove for screw 8 fixation. Specifically, the size of the square hole of the plate structure plate opening is 46x10 mm, and there is a 7 mm through hole for the pit screw 8 on the upper and lower sides. The folding edge width is 20 mm. The nylon parts are respectively fixed in the square holes of the steel plates to be connected, and the nylon parts are reversely fixed with self-tapping screws 8.

[0032] In order to solve the cabinet quality and durability problems caused by the fact that the corners cannot be completely covered with powder due to powder spraying after the overall molding, and at the same time reduce the impact of powder spraying on the connecting parts, the nylon parts and zinc alloy eccentric blocks 5 in this embodiment are inserted into the square holes of the steel plate after powder spraying and connected with screws 8.

[0033] On the other hand, this embodiment also provides a cabinet body using the above-mentioned detachable connector, wherein the panels of the cabinet body are previously connected by the detachable connector. The first connector 1 is embedded in one side of the panel of the cabinet body in the thickness direction, and the second connector 2, the operation hole 6 and the through hole are located on one side of the panel of the cabinet body in the length and width direction, thereby realizing vertical connection of the two panels to form a cabinet body.
