Description

Technical Field

[0001] This invention relates to the field of triangular lock technology, specifically a convenient triangular lock mechanical latch. Background Technology

[0002] In manufacturing, logistics, and other fields, the assembly and disassembly of enclosures is a common operation. Traditional connection methods typically use bolts and nuts to connect enclosure components. However, this method requires regular inspection and maintenance to ensure the fastening force and reliability of the connection. In addition, installation and disassembly usually require tools and a considerable amount of time. In many industries and applications, the connection and fixation of enclosure components are crucial because they guarantee the structural strength and sealing of the enclosure. However, traditional bolted connections may lead to gaps between enclosure components due to loosening or vibration, affecting the sealing and stability of the enclosure. Furthermore, assembly using traditional bolts and nuts requires a significant amount of manpower, material resources, and financial resources, and the operation is complex and inefficient. Therefore, we propose a convenient triangular lock mechanical buckle. Summary of the Invention

The connecting component and the tensioning component cooperate with each other. A snap-fit ​​component is installed on the circumferential surface of the connecting post. The rotating component drives the snap-fit ​​component to rotate.

[0007] Furthermore, the disassembly assembly includes a slot, a toggle post, an L-shaped groove, a retaining ring, a first locking head, and a first spring. Slots are provided in the center of the triangular side of the triangular block. The toggle post is slidably connected to the front end of the internally threaded tube. A triangular slot is provided at the rear end of the toggle post, and the triangular block engages inside the triangular slot. Three L-shaped grooves corresponding to the slots are provided on the side of the toggle post. One end of the short arm of the L-shaped groove communicates with the slot, and one end of the long arm of the L-shaped groove passes through the front end of the toggle post. A retaining ring is fixed inside the short arm of the L-shaped groove. A first locking head engages inside the slot. A first spring is fixed on the end face of the first locking head away from the slot. The first spring is fixed on the end face of the retaining ring. The disassembly assembly drives the triangular block to rotate.

[0008] Furthermore, it also includes a toggle assembly, which includes a first pull cord, a turntable, and a rotating ring. The first pull cord is slidably connected inside each L-shaped groove. The rear end of the first pull cord is connected to the end face of the first locking head. The front end of the toggle post is rotatably connected to the turntable. A rotating ring is fixed on the circumference of the turntable. The front end of the first pull cord is fixed to the rear end of the rotating ring. By setting the toggle assembly, the three first locking heads are moved.

[0009] Furthermore, the fixing component includes an externally threaded tube and a nut. The rear end of the internally threaded tube is fixed with an externally threaded tube, and a nut is threaded onto the circumferential surface of the externally threaded tube. The internally threaded tube is fixed to the housing component by setting the fixing component.

[0010] Furthermore, the connecting assembly includes a cross-shaped through groove, a mounting ring, a slide rod, a second locking head, and a second spring. The rear end of the connecting post has a cross-shaped through groove, and a mounting ring is fixed inside each end of the cross-shaped through groove.

[0015] Furthermore, an anti-slip plate is fixed to the left end of the front side of the card plate, and evenly distributed anti-slip strips are fixed to the front side of the anti-slip plate. By setting the anti-slip plate, the firmness of fixing the two boxes of the box assembly can be improved.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This convenient triangular lock mechanical buckle has the following advantages:

[0017] 1. First, make through holes on the front or front and back sides of the lower box assembly to be assembled and fix internal threaded tubes. Then, insert the actuating pin into the internal threaded tube. After insertion, the triangular slot at the rear end of the actuating pin connects with the triangular block inside the internal threaded tube. Then, rotate the threaded disc clockwise by the actuating pin to make it rotate and move it forward. In this case, the card plate will also rotate clockwise and move forward. When the anti-slip plate fixed on the side of the card plate is tightly attached to the inner wall of the upper box, pull out the actuating pin. Then repeat the above operation to make the remaining four anti-slip plates fit with the inner wall of the upper box to complete the assembly of the box assembly. It is very convenient.

[0018] 2. When disassembly is required, simply connect the actuating post to the triangular latch, and then rotate the triangular latch counterclockwise to separate the anti-slip plate from the inner wall of the upper box, which can be quickly removed. It is extremely fast.

[0019] 3. By setting the first locking head, after the triangular locking block is engaged in the triangular locking slot opened at the rear end of the toggle post, the three second locking heads located inside the triangular locking slot will be inserted into the three locking slots opened on the side of the triangular locking block under the action of the three second springs. In this way, the triangular locking block can be firmly connected to the triangular locking slot, thereby preventing the triangular locking block from falling out of the triangular locking slot when rotating.

[0020] 4. By setting up a toggle component, after the card plate has been rotated, the turntable can be rotated to make the rotating ring move and drive the three first pull ropes connected to it to move. The movement of the three first pull ropes pulls the three second card heads to move and separate them from the three card slots opened on the side of the triangular card block. After separation, the toggle column can be quickly pulled out. Attached Figure Description

[0041] The working principle of the convenient triangular lock mechanical buckle provided by this invention is as follows: First, through holes are made on the front or front and back sides of the lower box assembly to be assembled. There can be 1-2 through holes on each side. After the holes are made, the external threaded tubes 51 are installed into the through holes one by one. Then, each nut 52 is rotated to move each internal threaded tube 1 to the front or front and back sides of the lower box assembly. After connection, one of the pull rods 73 is pulled to move the second locking head 64 into the cross through groove 61. Then, the connecting ring 81 is fitted onto the rear end of the circumferential surface of the connecting post 23. After the connection is completed, the pull rod 73 is released. At this time, the second locking head 64 is engaged. Under the action of the second spring 65, the second locking head 64 enters the connecting groove inside the connecting ring 81, fixing the connecting ring 81. After the connecting ring 81 is fixed, the locking plate 82 can be connected to the connecting post 23. After connection, the remaining locking plates 82 are connected to the remaining connecting posts 23 according to the above steps. After connection, the upper box of the housing assembly is placed on top of the lower box. Then, the actuating post 32 is inserted into one of the internal threaded tubes 1. After insertion, the triangular locking block 22 located inside the internal threaded tube 1 engages with the triangular locking groove at the rear end of the actuating post 32. At the same time, the first locking head located inside the L-shaped groove 33... Under the action of the first spring 36, 35 is inserted into the slot 31 opened on the side of the triangular block 22. Then, by rotating the fixed column 10 connected to the actuating column 32 clockwise, the threaded disc 21 rotates clockwise and moves forward. During the clockwise rotation and forward movement of the threaded disc 21, the card plate 82 rotates clockwise and moves forward. When the anti-slip plate 12 fixed on the side of the card plate 82 is tightly pressed against the inner wall of the upper box, the rotation of the actuating column 32 stops. Then, the turntable 42 connected to the front end of the actuating column 32 is rotated, causing the rotating ring 43 to rotate and drive the rotation of the card plate 82. The three first pull ropes 41 connected to it move, and the movement of the three first pull ropes 41 pulls the three second clips 64 to move and separate from the three clip slots opened on the side of the triangular clip 22. After separation, the actuating post 32 can be pulled out. Then, repeat the above operation to firmly attach the anti-slip plate 12 fixed on the side of the remaining clip plate 82 to the inner side wall of the upper box to complete the connection of the two boxes of the box assembly. When disassembly is required, simply connect the actuating post 32 to each triangular clip 22, and then rotate each triangular clip 22 counterclockwise to separate each anti-slip plate 12 from the inner side wall of the upper box, and it can be quickly removed, which is extremely fast.
