Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 , Figure 2As shown in the figure, this application embodiment proposes an adjustable pin assembly, including three mutually cooperating pins and a socket. The socket includes a base 7, a fixing block 4, and an adjustment mechanism between the fixing block 4 and the base 7. The adjustment mechanism is used to adjust the fixing block 4 relative to the base 7 to achieve multi-directional horizontal displacement. The fixing block 4 has a plug-in interface at one end near the pin, and the pin and the plug-in end are inserted into the plug-in interface.

[0015] First, it should be noted that the three pins and the socket are installed on the trolley and the box respectively. Before installation, the position of the fixing block 4 is adjusted by adjusting the mechanism so that the three pins can be stably inserted into the socket, achieving a stable fit and improving the efficiency of the installation and replacement process.

[0016] The adjustment mechanism includes a first mounting groove located in the middle of the base 7. The first mounting groove has multiple side walls around it. The size of the first mounting groove is larger than the size of the fixing block 4. The fixing block 4 is placed in the first mounting groove. Each of the multiple side walls of the first mounting groove is threaded with a first tightening bolt 5. The protruding end of the first tightening bolt 5 abuts against the outer wall of the fixing block 4. That is, by adjusting the multiple first tightening bolts 5 sequentially or simultaneously, the position of the fixing block 4 and the insertion interface is aligned with the position of the pin 3, so as to achieve stable and accurate installation.

[0017] To improve the stability of the installation process, this embodiment also includes a positioning seat 6, which is disposed in the first mounting groove, and the first tightening bolt 5 abuts against the outer wall of the positioning seat 6. The positioning seat 6 has a second mounting groove at one end facing the fixing block 4, and the fixing block 4 and the second mounting groove are in a one-way linear sliding fit. The positioning seat 6 is provided with second tightening bolts at both ends along the sliding direction of the fixing block 4, and the second tightening bolts abut against both ends of the sliding direction of the fixing block 4. The fixing block 4 is first placed in the second mounting groove, and its position in the second mounting groove is adjusted. Then the positioning seat 6 is placed in the first mounting groove, and the position of the positioning seat 6 is adjusted by the first tightening bolt 5. This avoids the instability that may occur during the adjustment process when the fixing block 4 is directly placed in the first mounting groove.

[0018] Specifically, the three-piece plug includes a mounting plate 1, on which a plug 3 is slidably mounted. The plug 3 engages with the insertion interface. A limiting mechanism is provided between the plug 3 and the mounting plate 1. The limiting mechanism includes a spring 2 disposed between the mounting plate 1 and the plug 3. The plug 3 has a first locking member, and the mounting plate 1 has a second locking member. When the spring 2 presses the plug 3 into the insertion interface, the first locking member and the second locking member engage. When the plug 3 is driven away from the fixing block 4, the spring 2 deforms, and the first locking member and the second locking member disengage. In use, by driving the plug 3, it is inserted into the insertion interface. At this time, the plug 3 is kept pressed in the insertion interface under the force of the spring 2, and the first locking member and the second locking member engage simultaneously, ensuring a stable fit after installation.

[0019] Furthermore, two sliding sleeves are coaxially spaced on the mounting plate 1, and the pin 3 is slidably disposed in the two sliding sleeves; the spring 2 is slidably sleeved on the outside of the pin 3; the first snap-fit ​​component includes a snap-fit ​​rod disposed on the outer wall of the pin 3, the snap-fit ​​rod being located between the two sliding sleeves, one end of the spring 2 abutting against the snap-fit ​​rod and the other end abutting against the sliding sleeve furthest from the fixing block 4; the second snap-fit ​​component includes a snap hook disposed on the mounting plate 1; when the snap-fit ​​rod and the snap hook are engaged, the spring 2 is in a compressed state, and the pin 3 is inserted into the insertion interface; when disassembly is required, a force is applied to the pin 3 in a direction away from the fixing block 4, the spring 2 is compressed, and the pin 3 leaves the insertion interface, and the snap-fit ​​rod moves away from the snap hook through displacement and rotation, thereby achieving disassembly of the structure.

[0020] In summary, this utility model proposes an adjustable pin assembly. The pin 3 and the insertion hole are respectively installed on the trolley and the housing. Before installation, the position of the fixing block 4 is adjusted via an adjustment mechanism, ensuring the pin 3 can be stably inserted into the insertion interface, achieving a stable fit and improving the efficiency of installation and replacement. Furthermore, the design of the first mounting slot, the second mounting slot, the first tightening bolt 5, and the second tightening bolt allows for multi-directional adjustment of the fixing block 4, facilitating operation. The compression and reset action of the spring 2 ensures that the pin 3, even without force, is stably inserted into the insertion interface under the force of the spring 2, preventing disengagement and guaranteeing connection stability. During disassembly, the driving locking rod compresses the spring 2, causing the locking rod and the locking hook to disengage, and the pin 3 leaves the insertion interface, achieving disassembly. The overall structure is convenient to operate and structurally stable.
