Description

Technical Field

[0001] The utility model relates to the technical field of magnetic lock buckles, in particular to a magnetic lock buckle and a child anti-lost rope. Background Art

[0002] Children's anti-lost rope is a popular product. At present, many parents use children's anti-lost rope to connect themselves and their children when they are outdoors to prevent children from getting lost. However, due to the long connection rope, when parents take their children to the activity area, the long connection rope affects the children's activities. Therefore, a convenient and quick way is needed to facilitate parents to untie the connection with their children.

[0003] For example, Chinese patent CN 209473787 U discloses a magnetic lock and a child-proof belt having a magnetic lock, which can unlock the magnetic lock by moving a magnetic component in the lock buckle through a magnetic key.

[0004] The prior art still has the following deficiencies:

[0005] 1. Children are naturally curious about other things and are very active, so they are easy to disassemble the magnetic lock, which affects the normal use of the magnetic lock. Many magnetic locks on the market are complicated to assemble, so it is not convenient for parents to install and repair the magnetic locks at any time, which affects the normal use of the anti-lost rope.

[0006] 2. The reference document uses a hook structure to lock the male buckle and the female buckle. However, after long-term use, the hook will often be squeezed and bent, which can easily cause material fatigue or even breakage, affecting the connection effect of the male buckle and the female buckle. The broken hook cannot work normally, which affects the service life of the lock. Utility Model Content

[0055] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0056] like Figure 1-Figure 5 A magnetic lock buckle is shown, comprising:

[0057] The lock housing 1 is hollow inside, and one end of the lock housing 1 is opened to form a socket 13;

[0058] The lock body 2 has a lock slot 21 and a through slot 22 formed thereon. The lock slot 21 and the through slot 22 are connected, and the through slot 22 passes through the insertion end 24 of the lock body 2. The insertion end 24 of the lock body 2 can be inserted into the interior of the lock housing 1 through the socket 13;

[0059] A lock pin 3 having magnetism, the lock pin 3 is movably arranged in the lock housing 1, and the lock pin 3 can cooperate with the lock slot 21, so that the lock body 2 cannot be separated from the lock housing 1;

[0060] The key 6 has a magnetic object disposed therein, and the magnetic object can attract the lock pin 3 .

[0061] When the key 6 is used to approach the lock housing 1, the lock pin 3 can be driven to move by the key 6, thereby changing the current working state of the magnetic lock.

[0062] The through slot 22 is used to avoid the connecting column 52;

[0063] When the lock body 2 is inserted into the lock housing 1 , the connecting column 52 can enter the middle part of the lock body 2 through the through slot 22 , and the lock pin 3 can be snapped into the lock slot 21 , thereby achieving the connection between the lock body 2 and the lock housing 1 .

[0064] An insertion hole 11 is formed on the upper end surface of the lock shell 1, a connecting column 52 is formed inside the lock shell 1, and a through hole 33 is formed on the lock pin 3, so that the lock pin 3 can be sleeved on the outside of the connecting column 52 through the insertion hole 11, so that the lock pin 3 can be conveniently set inside the lock shell 1.

[0065] The connecting column 52 can also limit the movement path of the lock pin 3, so that the lock pin 3 can move along the vertical direction of the connecting column 52, so that when the lock body 2 and the lock shell 1 are matched, it can be ensured that the lock pin 3 and the lock body 2 can be matched accurately and stably.

[0066] Specific as Figure 3 and Figure 4As shown, the insertion hole 11 is used to pass the fixing sleeve 4, and the fixing sleeve 4 is formed with a sleeve portion 42, so that the sleeve portion 42 can be sleeved on the outside of the connecting column 52, so that the fixing sleeve 4 is connected to the connecting column 52, and the sleeve portion 42 and the connecting column 52 can be matched by threaded connection or interference fit. In this embodiment, the preferred connection method is that the sleeve portion 42 and the connecting column 52 are connected together by interference fit.

[0067] The diameter of the through hole 33 matches the outer diameter of the fixing sleeve 4 , so that the locking pin 3 can be sleeved outside the fixing sleeve 4 and can move up and down along the fixing sleeve 4 .

[0068] The through groove 22 is used to avoid the fixing sleeve 4 and the lock pin 3 sleeved on the outside of the fixing sleeve 4. When the fixing sleeve 4 and the fixing member 5 are inserted into the lock housing 1, the sleeve portion 42 can be connected to the outside of the connecting column 52. Part of the lock pin 3 will be placed in the lock groove 21 and cooperate with the lock groove 21 to perform the locking action.

[0069] like Figure 1-Figure 4 As shown, the lower end surface of the lock housing 1 is further provided with an insertion hole 12 , and the insertion hole 12 is used for passing the fixing member 5 , and the connecting column 52 is arranged on the fixing member 5 .

[0070] The positions of the first insertion hole 11 and the second insertion hole 12 correspond to each other, so that the fixing sleeve 4 and the fixing member 5 can be connected to each other.

[0071] like Figure 1-Figure 5 As shown, the lock pin 3 includes a supporting portion 31 and a locking portion 32, and the supporting portion 31 can be inserted into the through slot 22. The diameter of the locking portion 32 is larger than the diameter of the supporting portion 31. And the profile of the locking portion 32 matches the shape of the lock slot 21, so that the locking portion 32 can be placed in the lock slot 21 from above the lock slot 21.

[0072] When the lock body 2 is connected to the lock housing 1 , the locking portion 32 is inserted into the lock groove 21 , so the lock body 2 and the lock housing 1 cannot be separated from each other by lateral movement, so that the lock housing 1 and the lock body 2 are connected as one.

[0073] Furthermore, a scooping slope 25 is formed on the insertion end 24 .

[0074] When the insertion end 24 enters the lock housing 1, the end of the scooping slope 25 moves below the locking portion 32. As the lock body 2 continues to move, the edge of the support portion 31 contacts the scooping slope 25 and moves upwards under the action of the scooping slope 25, thereby gradually raising the height of the lock pin 3. The locking portion 32 of the lock pin 3 can move to a height higher than the upper end surface of the lock slot 21, so that the lock pin 3 can be placed in the lock slot 21, thereby completing the locking.

[0075] In this process, the scooping inclined surface 25 is provided to tilt and lift the lock pin 3, and the lock pin 3 is restricted by the fixing sleeve 4 and the fixing member 5, so it can only move in the vertical direction, and will not move horizontally. Since the structure is simple and reliable, it is not easy to be damaged during the locking process. Even if a small part of the insertion end 24 of the lock body 2 is damaged, if the structure of the scooping inclined surface 25, the lock groove 21 and the through groove 22 is not completely damaged, the lock body 2 can still be used normally.

[0076] like Figure 1-Figure 5 As shown, a step portion 14 is formed on the circumferential side of the insertion hole 11, and a supporting surface 41 is formed on the end of the fixing sleeve 4. The circumferential side of the supporting surface 41 abuts against the step portion 14, so that the sleeve portion 42 on the fixing sleeve 4 can enter the lock housing 1.

[0077] A second step portion 15 is formed around the second insertion hole 12 , and a second supporting surface 51 is formed at the end of the fixing member 5 . The second supporting surface 51 abuts against the second step portion 15 , so that the connecting column 52 on the fixing member 5 can enter the lock housing 1 .

[0078] When the fixing sleeve 4 and the fixing member 5 enter the lock housing 1 from the insertion hole 11 and the insertion hole 2 12 respectively and are connected, the fixing sleeve 4 and the fixing member 5 can be arranged on the lock housing 1. The second step portion 14 and the second step portion 15 can limit the position of the fixing sleeve 4 and the fixing member 5, prevent the fixing sleeve 4 and the fixing member 5 from moving when connected, and ensure the stable working state of the lock buckle.

[0079] Specific as Figure 3 and Figure 4 As shown, the outer sleeve of the fixing sleeve 4 or the fixing member 5 is provided with a reset spring 7, one end of the reset spring 7 abuts against the top support surface 1 41 or the top support surface 2 51, and the other end of the reset spring 7 abuts against the lock pin 3.

[0080] When the lock body 2 is inserted into the lock housing 1, the lock pin 3 is pressed into the lock slot 21 under the action of the reset spring 7, so that the lock catch has a stable working state and can perform the locking action more quickly.

[0081] like Figure 1-Figure 5 As shown, a groove 23 is formed on the lock body 2 , and the lock groove 21 is formed inside the groove 23 .

[0082] A locking portion 32 is formed by bending at the upper end of the supporting portion 31 .

[0083] A gap is formed between the groove 23 and the inner side of the upper end surface of the lock housing 1 , and the height of the gap is at least greater than the height of the locking portion 32 , so that the locking portion 32 can move in the groove 23 .

[0084] like Figure 6The child anti-lost rope shown includes a magnetic lock as described above; it also includes a connecting rope 8, a child-end wristband 81 and a parent-end wristband 82, wherein the child-end wristband 81 and the parent-end wristband 82 are respectively arranged at the two ends of the connecting rope 8.

[0085] A connecting portion 16 is formed on the lock shell 1 , and a connecting portion 26 is formed on the lock body 2 . The connecting portion 16 and the connecting portion 26 are used to connect two ends of the child-end wristband 81 .

[0086] Furthermore, the key 6 is hung on the parent-side wristband 82 to prevent the key 6 from being lost, and it is also convenient when unlocking the child-side wristband 81.

[0087] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
