The provision of the connecting ear connected to the first movable shaft enables the movable member to freely reciprocate along the first movable shaft to perform the locking action.

[0015] Furthermore, a buffer spring is provided on the first movable shaft. The provision of the buffer spring can protect the movable member and the fixing member to prevent direct collision and damage between the movable member and the fixing member when the first magnet attracts.

[0016] Furthermore, a first installation cavity is provided at the other end of the movable member relative to the locking pin, and the first attracting member is disposed in the first installation cavity. A protecting edge protrudes outward along the periphery of the first installation cavity, and the height of the protecting edge is slightly higher than the height of the first attracting member.

[0020] Further, an inner groove matching the first fixing cylinder is provided along the periphery of the movable member. The movable member is clamped between the lock body rear cover and the fixing member through the inner groove. By providing the inner groove, the movable member can be restricted between the first fixing cylinders, and a left-right limiting effect on the movable member can be formed without affecting the axial movement of the movable member.

[0021] Further, the first attracting member is a magnet, and a second attracting member is provided at the other end of the lock body rear cover relative to the first fixing cylinder. The second attracting member provided on the lock body rear cover can cooperate with the first attracting member to attract the movable member away from the fixing member when not working, so that the movable member does not lock the locking member, which is convenient for the insertion of the locking pin.

[0022] Further, a fourth installation groove is provided at the other end of the lock body rear cover relative to the first fixing cylinder. A clamping member is provided along the periphery of the fourth installation groove. The second attracting member is installed in the fourth installation groove through the clamping member.

During assembly, the fixing member can be further limited to avoid the fixing member shaking and affecting the locking operation.

[0024] Further, the lock pin assembly further includes a lock pin detachably connected to the lock pin seat. The lock pin extends downward to form a locking portion, and a concave locking groove is provided on the locking portion. The size of the locking groove matches that of the locking protrusion. The split structure facilitates installation, disassembly and maintenance. The concave arc-shaped locking groove can increase the smoothness when the locking portion is inserted into the locking protrusion, and the phenomenon of jamming will not occur.

[0025] Further, a second installation cavity is provided in the lock pin, and the first magnet is installed in the second installation cavity. This facilitates the installation and disassembly of the first magnet.

[0026] Further, the key assembly includes a key housing and a key outer cover that are detachably connected. A third installation cavity is formed on the key housing, and the second magnet is installed in the third installation cavity. This facilitates the installation and disassembly of the second magnet.

[0027] Compared with the prior art, the present utility model has the following advantages: The movable part of the present utility model can perform axial movement along the first movable axis. A latch and a first adsorbent are provided on the movable part. When the lock pin of the lock pin assembly is inserted into the first locking hole, the locking protrusion of the locking member will be forced by the torsion spring ring to sink into the locking groove of the locking portion. At the same time, under the magnetic force of the first magnet, the first adsorbent will be adsorbed. Driven by the first adsorbent, the movable part moves towards the lock pin, and the latch will be inserted into the first locking hole of the locking member as the movable part moves, locking the locking member so that it cannot stretch and disengage from the locking groove, thereby realizing the locking of the lock pin. When unlocking is required, bring the key assembly close to the outer cover of the lock body. At this time, since the magnetic force of the second magnet is greater than that of the first magnet, the first adsorbent will drive the movable part to move towards the key assembly. At this time, the latch disengages from the first locking hole, unlocking the locking member, and the locking member can stretch. Then, the lock pin assembly can be pulled out. The present utility model uses lock pin assemblies and key assemblies with different magnetic forces to adsorb the movable part inside the lock body to realize the opening and closing actions of the lock body, which can achieve a completely hidden installation. There is no need to set a keyhole on the lock body. In this way, the lock body can be ignored when designing the gift box, and a more complete and beautiful design can be achieved; furthermore, for friends, the unlocking action can be demonstrated interestingly, which can promote the communication between the two parties.

By providing the inner groove 235, the movable member 23 can be restricted between the first fixing columns 2141, forming a left-right limiting effect on the movable member 23 without affecting the axial movement of the movable member 23.

[0057] Further, the first attracting member 232 is a magnet, a permanent magnet or other magnetic members with magnetism. A second attracting member 4 is provided at the other end of the lock body rear cover 214 relative to the first fixing cylinder 2141. In this embodiment, the second attracting member is an iron sheet, and of course it can also be other metal sheets. The second attracting member 4 provided on the lock body rear cover 214 can cooperate with the first attracting member 232 to suck the movable member 23 away from the fixing member 24 when not working, so that the movable member 23 will not lock the locking member 22, facilitating the insertion of the lock pin 12. A fourth installation groove 2142 is provided at the other end of the lock body rear cover 214 relative to the first fixing cylinder 2141. A clamping member 2143 is provided along the periphery of the fourth installation groove 2142. The second attracting member 4 is installed in the fourth installation groove 2142 through the clamping member 2143. Installing the second attracting member 4 on the lock body rear cover 214 through the clamping member 2143 facilitates the installation and disassembly of the second attracting member 4.

[0058] Further, a positioning convex block 215 is provided inside the lock body housing 21, and a positioning groove 249 matching the positioning convex block 215 is provided on the fixing member 24. During assembly, the fixing member 24 can be further limited to avoid the fixing member 24 shaking and affecting the locking operation.

[0059] As Figure 12 and Figure 13 shown, a second magnet 31 is provided on the key assembly 3. The magnetic force of the second magnet 31 is greater than that of the first magnet 13. The key assembly 3 includes a key housing 32 and a key outer cover 33 that are detachably connected. A third installation cavity 321 is formed on the key housing 32, and the second magnet 31 is installed in the third installation cavity 321. This facilitates the installation and disassembly of the second magnet 31.

[0060] A brief description of the working principle of the present utility model: When in use, as Figure 14, just insert the locking pin 12 of the locking pin assembly 1 into the first connection hole 211. During the insertion of the locking pin 12, the latching protrusion 2231 will be pushed back into the interior of the lock body housing 21 until the locking pin 12 is completely pressed into the first connection hole 211. At this time, the locking groove 122 is just positioned at the assembly position of the latching protrusion 2231. The latching protrusion 2231 will abut against the locking groove 122 under the action of the first elastic member 222. At the same time, as the locking pin 12 is inserted, the first magnet 13 installed in the locking pin 12 will get closer and closer to the position of the first attracting member 232 in the movable member 23. When it reaches the range of the magnetic force action, the first magnet 13 will attract the first attracting member 232. Since the locking pin assembly 1 is fixed after insertion, the first attracting member 232 will drive the movable member 23 to move towards the first magnet until the movable member 23 abuts against the fixed member 24. At this time, the latch pin 231 provided on the movable member 23 will move through the first through hole 244 as the movable member 23 moves, and then insert into the first locking hole 2232 on the locking member 22. At this time, the locking member 22 will be blocked by the latch pin 231 and cannot move, so that the latching protrusion 2231 remains in a state of tightly abutting against the locking groove 122, and thus the locking action of the locking pin assembly 1 can be realized;

[0061] Unlocking action: During use, just bring the key assembly 3 close to the end of the outer cover of the lock body 2. Since the magnetic force of the second magnet 31 is greater than the magnetic force of the first magnet 13, when the key assembly 3 is close, the second magnet 31 will attract the first attracting member 232. The first attracting member 232 will drive the movable member 23 to move towards the outer cover of the lock body 2. As a result, the latch pin 231 disengages from the first locking hole 2232. At this time, the locking member 22 is not blocked by the latch pin 231 and can rotate along the first movable shaft 246, and the locking pin assembly 1 can be pulled out at will to complete the unlocking action.

[0062] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
