Description

Technical Field

[0001] This utility model relates to the technical field of metal cabinet connecting components, specifically to a universal buckle connector. Background Technology

[0002] Currently, the connection methods between custom metal cabinet panels are mostly welding and screw fastening. However, these connection methods have many problems.

[0003] Welding is a highly skilled process that requires skilled workers. It is complex and often rough, and improper handling can easily lead to rust and weld failure, resulting in an unsightly appearance. Furthermore, on-site installation is cumbersome, time-consuming, and inefficient. Welded connections also make it nearly impossible to disassemble stainless steel cabinets without damage, hindering the relocation, repair, or replacement of parts from metal cabinets.

[0004] The screw fastening process requires the filling of embedded parts inside the plate during production. The embedded parts need to be accurately positioned, which consumes production time. Furthermore, if a problem is found with the embedded parts during installation, they cannot be replaced, which will cause the plate to be scrapped.

[0005] Therefore, there is an urgent need for a connector that is easy to install and disassemble, reliable in connection, and convenient for modular installation of metal cabinets. Utility Model Content

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed by this utility model.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Refer to Figure 1 to Figure 10 A universal fastener includes a cavity 1, a transmission mechanism, a tensioning mechanism, and a locking mechanism. The transmission mechanism, tensioning mechanism, and locking mechanism are all disposed within the cavity 1. The transmission mechanism is connected to the tensioning mechanism, and the tensioning mechanism is connected to the locking mechanism. The transmission mechanism drives the tensioning mechanism to move, thereby driving the locking mechanism to move to achieve a locked or unlocked state.

[0039] Specifically, in this embodiment, the cavity 1 is composed of a first housing 11 and a second housing 12. The first housing 11 is provided with a positioning mounting hole 111, and both ends of the second housing 12 are provided with positioning mounting pins 121. The positioning mounting pins 121 cooperate with the positioning mounting hole 111. Through the cooperation of the positioning mounting pins 121 and the positioning mounting hole 111, the first housing 11 and the second housing 12 can be stably connected.

[0040] Specifically, in this embodiment, one end of the first housing 11 is provided with an operation hole 112 that exposes the transmission mechanism, through which the transmission mechanism can be operated.

[0041] Specifically, in this embodiment, a reversing part is provided on the inner sidewall of the second housing 12, and the reversing part is a hemispherical protrusion 122.

[0042] Specifically, in this embodiment, one end of the second housing 12 is provided with a mounting hole 123 for mounting the transmission mechanism and a transmission groove 124 for mounting the tensioning mechanism.

[0043] Specifically, in this embodiment, the transmission mechanism is an internal hexagonal gear 2, and the bottom end of the internal hexagonal gear 2 is provided with a rotating shaft 21.

[0044] Specifically, in this embodiment, the tensioning mechanism is a multi-tooth transmission bolt 3. One end of the multi-tooth transmission bolt 3 has a thread 31, and the other end has a transmission tooth 32. The transmission tooth 32 is connected to the internal hexagonal gear 2.

[0045] Specifically, in this embodiment, the locking mechanism is a guide locking post 4. One end of the guide locking post 4 is provided with a locking block 41, and the other end is provided with an internal thread 42. The guide locking post 4 is threadedly connected to the tensioning mechanism.

[0046] Specifically, in this embodiment, a reversing guide groove 43 extends axially along the cylindrical surface of the guide locking post 4. The two ends of the reversing guide groove 43 are parallel to the axial direction of the guide locking post 4, and the middle part of the reversing guide groove 43 is bent radially along the guide locking post 4. The reversing guide groove 43 cooperates with the reversing part. It should be noted that when the multi-tooth transmission bolt 3 rotates, it drives the guide locking post 4 to move linearly. During this movement, the reversing guide groove 43 cooperates with the hemispherical protrusion 122, causing the guide locking post 4 to rotate 90 degrees, thereby locking or releasing the locking block 41.

[0047] Specifically, in this embodiment, the internal hexagonal gear 2 is installed in the mounting hole 123 for easy operation with tools such as an internal hexagonal wrench, the transmission gear 32 is installed in the transmission groove 124, and the multi-tooth transmission bolt 3 can rotate under the drive of the transmission mechanism.

[0048] When using the universal buckle connector of this utility model, after installing universal buckles on the left and right sides of the shelf, top plate, bottom plate and back plate, the side plate is pre-installed with slots at the horizontal position of the assembled top plate, bottom plate, shelf and back plate. Then, the top plate, bottom plate, shelf and back plate are slid into the slots of the side plate in sequence. The transmission mechanism is operated through the operation hole 112 by a tool. The transmission mechanism drives the tensioning mechanism to move, which in turn drives the locking mechanism to move, so that the locking block 41 is tightly fixed in the slot of the side plate, realizing the connection between the top plate, bottom plate, shelf and back plate and the side plate. When disassembling, the transmission mechanism can be reversed to loosen it, which is convenient for disassembly.

[0049] Example:

[0050] Please see Figures 1 to 10In this embodiment of the utility model, a universal fastener includes a cavity 1, a transmission mechanism, a tensioning mechanism, and a locking mechanism, all of which are disposed within the cavity 1.

[0051] The cavity 1 consists of a first housing 11 and a second housing 12. The first housing 11 is provided with a positioning mounting hole 111, and both ends of the second housing 12 are provided with positioning mounting pins 121. The positioning mounting pins 121 cooperate with the positioning mounting holes 111 to connect and fix the first housing 11 and the second housing 12. One end of the first housing 11 is provided with an operation hole 112 that exposes the transmission mechanism, facilitating the operation of the transmission mechanism.

[0052] The inner wall of the second housing 12 is provided with a hemispherical protrusion 122 as a reversing part. One end of the second housing 12 is provided with a mounting hole 123 for mounting the transmission mechanism and a transmission groove 124 for mounting the tensioning mechanism. Both ends of the second housing 12 are provided with positioning mounting pins 121.

[0053] The transmission mechanism is an internal hexagonal gear 2. The bottom end of the internal hexagonal gear 2 is provided with a rotating shaft 21. The internal hexagonal gear 2 is installed in the mounting hole 123. The internal hexagonal gear 2 can be rotated by an internal hexagonal wrench.

[0054] The tensioning mechanism is a multi-tooth drive bolt 3. One end of the multi-tooth drive bolt 3 has a thread 31, and the other end has a drive tooth 32. The drive tooth 32 is connected to the internal hexagonal gear 2. The drive tooth 32 is installed in the drive groove 124. When the internal hexagonal gear 2 rotates, it will drive the multi-tooth drive bolt 3 to rotate.

[0055] The locking mechanism is a guide locking post 4. One end of the guide locking post 4 is provided with a locking block 41, and the other end is provided with an internal thread 42. The guide locking post 4 is threadedly connected to the multi-tooth transmission bolt 3. A reversing rail guide groove 43 is provided extending axially along the cylindrical surface of the guide locking post 4. The two ends of the reversing rail guide groove 43 are parallel to the axial direction of the guide locking post 4, and the middle part of the reversing rail guide groove 43 is bent along the radial direction of the guide locking post 4. The reversing rail guide groove 43 cooperates with the hemispherical protrusion 122.

[0056] The working principle of this embodiment is as follows: When connecting the top panel, bottom panel, shelves, back panel, and side panels of the cabinet, first pre-install the corresponding horizontal slots on the side panels, and then install the universal fastener on the left and right sides of the top panel, bottom panel, shelves, and back panel. Next, slide the top panel, bottom panel, shelves, and back panel into the slots on the side panels in sequence. Use an Allen wrench to rotate the Allen gear 2 through the operating hole 112. The Allen gear 2 drives the multi-tooth transmission bolt 3 to rotate, causing the guide locking pin 4 to move linearly. During this movement, the guide groove 43 engages with the hemispherical protrusion 122, causing the guide locking pin 4 to rotate 90 degrees. The locking block 41 is then firmly fixed to the slot on the side panel, thus achieving a locked connection between the panels. When disassembly is required, rotate the Allen gear 2 in the opposite direction, causing the multi-tooth transmission bolt 3 to rotate in the opposite direction. The guide locking pin 4 moves in the opposite direction, and the locking block 41 is released, allowing the panels to be removed.

[0057] In summary, this utility model has the following beneficial effects:

[0058] This universal connector allows for quick assembly of cabinet panels using only an Allen wrench, and it can be repeatedly disassembled and reassembled, greatly reducing later maintenance costs.

[0059] The structural design is practical and can be used for all types of metal cabinets. It also allows for stepless adjustment and locking between panels, achieving a seamless effect between horizontal and vertical panels.

[0060] The standardized production process improves production efficiency. No screws are required for fastening, and only one universal fastener is needed on-site to achieve universal installation of all cabinets. The process is simple and the appearance is beautiful.

Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model.
