Description
Technical Field
[0001] This utility model relates to the field of magnetic locking technology, specifically a magnetic locking structure. Background Technology
[0002] Magnetic locks are devices that use magnets to unlock, such as anti-theft magnetic locks in supermarkets and storage bags with magnetic locks. However, the existing magnetic locks have a locking bar (pin-shaped structure) that is directly fixed to a disc. The disc is a detachable part. After unlocking with the magnet, you still need to hold the disc and pull the locking bar outwards, which is very cumbersome and needs to be improved. Utility Model Content
[0003] The purpose of this invention is to provide a magnetic latch structure that improves the problem that existing magnetic latches cannot automatically pull out the locking bar (needle-shaped structure) after unlocking.
[0004] This utility model is implemented as follows: A magnetic locking structure includes a bag body and a lock body assembly and a lock platform assembly fixedly installed on opposite sides of the opening of the bag body. The lock body assembly includes a cylindrical button rod, a base, and a rod section disposed between the cylindrical button rod and the base. The cylindrical button rod is slidably and telescopically connected in the rod section, and the rod section is slidably and telescopically connected to the base. A cavity is provided between the cylindrical button rod, the base, and the rod section. The lock body assembly also includes a locking rod disposed in the cavity and an elastic body I sleeved on the locking rod. The elastic body I is used for pressing and resetting the cylindrical button rod and the rod section.
[0005] Furthermore, the locking rod is fixed to the cylindrical button rod, one end of the elastic body is in contact with the top wall of the cylindrical button rod, and the other end of the elastic body is in contact with the bottom of the base, forming an elastic abutment against the cylindrical button rod.
[0006] Furthermore, the rod section may be configured as one or more.
[0007] Furthermore, the lock assembly includes a housing and a locking mechanism disposed inside the housing, the locking mechanism being used to lock the locking rod on the lock body assembly.
[0008] Furthermore, the locking mechanism includes an elastic body II, a bracket, and an upper limit cap that is slidably sleeved on the bracket. The elastic body II is disposed at the bottom of the bracket and elastically abuts against the bracket.
[0009] Furthermore, the bracket is made of a material with magnetic attraction properties.
[0010] Furthermore, the limiting cap is a hollow structure that is smaller at the top and larger at the bottom, and a through hole is provided at the top of the limiting cap.
[0011] Furthermore, the bracket is a hollow structure, and a partition layer is provided near the middle of the bracket. At least three clearance holes penetrating the outer wall of the bracket are provided on the bracket above the partition layer. A through hole is provided on the top of the bracket at a position corresponding to the through hole on the limiting cap.
[0012] Furthermore, the locking mechanism also includes at least three circular balls, which are movably disposed inside the bracket and located above the partition layer. The three circular balls are configured to correspond one-to-one with the clearance holes.
[0013] Furthermore, a locking hole is formed at the center of the three circular balls. When the cylindrical button is pressed, the locking rod on the cylindrical button passes through the through hole and the through hole and is locked into the locking hole, forming a locking state for the locking rod, and at the same time, fixing the opening of the bag body at the top and bottom.

[0025] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:
[0026] like Figures 1-7As shown, a magnetic lock structure includes a bag body 1 and a lock body assembly 2 and a lock platform assembly 3 fixedly installed on opposite sides of the opening of the bag body 1. The bag body 1 has a storage cavity for storing mobile phones or other items. In this embodiment, the upper and lower ends of the opening of the bag body 1 extend forward to form an upper edge 11 and a lower edge 12. The upper edge 11 and the lower edge 12 are both made of multiple layers of fabric or leather. An annular seat 4 is fixed to the upper edge 11 and the lower edge 12 by stitching within the leather or leather interlayer. The annular seat 4 is... Made of a material with a certain degree of hardness, the lock body assembly 2 and the lock platform assembly 3 are fixedly connected to the upper edge 11 and the lower edge 12 through the central hole on the annular seat 4. The lock body assembly 2 includes a cylindrical button rod 21, a base 22, and a rod section 23 disposed between the cylindrical button rod 21 and the base 22. There are one or more rod sections 23. The cylindrical button rod 21 is slidably and telescopically connected in the rod section 23, and the rod section 23 is slidably and telescopically connected to the base 22. There is a cavity between the cylindrical button rod 21, the base 22, and the rod section 23. Component 2 also includes a locking rod 24 disposed in the cavity and an elastic body 25 sleeved on the locking rod 24. The elastic body 25 is a spring or other elastic structure with a telescopic reset effect. The elastic body 25 is used for the pressing and reset of the cylindrical button rod 21 and the rod section 23. In this embodiment, the outer wall of one end of the cylindrical button rod 21 is provided with an outwardly protruding annular platform. The rod section 23 is a tubular structure with both ends connected to each other. The inner wall of the rod section 23 and the end corresponding to the annular platform on the cylindrical button rod 21 extends towards the axis to form a limit. The outer wall of the other end of the lever 23 protrudes outward to form an annular platform. The base 22 is a structure with its two ends connected to each other. The inner wall of the base 22 extends towards the axis at a position corresponding to the annular platform on the lever 23 to form a limiting platform. When the cylindrical button lever 21 and lever 23 are reset by the elastic body 25, the cylindrical button lever 21 and lever 23 slide outward or upward. Through the mutual cooperation of the limiting platforms and the annular platform set on the cylindrical button lever 21, lever 23 and base 22, the cylindrical button lever 21 and lever 23 are prevented from falling off.
[0027] In this way, the cylindrical button rod 21, the base 22, and the rod section 23 are connected. The cylindrical button rod 21 is slidably and telescopically connected to the rod section 23, and the rod section 23 is slidably and telescopically connected to the base 22. The elastic body 25 provides elastic support for the cylindrical button rod 21. When the magnetic lock is unlocked by the magnet, the elastic body 25 quickly resets the cylindrical button rod 21. At the same time as the cylindrical button rod 21 is reset, the locking rod fixed on the cylindrical button rod 21 is automatically pulled out from the locking platform assembly 3, which is very convenient to use.
[0028] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, the locking rod 24 is fixed on the cylindrical button rod 21, one end of the elastic body 25 contacts the top wall of the cylindrical button rod 21, and the other end of the elastic body 25 contacts the bottom of the base 22, forming an elastic abutment against the cylindrical button rod 21.
[0029] Thus, when the cylindrical button lever 21 is pressed, the elastic body 25 is compressed and deformed. At this time, the cylindrical button lever 21 retracts and hides inside the connected lever section 23, while the lever section 23 retracts and hides in the base 22. When the locking lever 24 on the cylindrical button lever 21 is inserted into the locking platform assembly 3, the magnetic lock is locked. Moreover, the lock body assembly 2 is fixedly connected to the bag body 1. To lock, it is only necessary to press the cylindrical button lever 21 until it is engaged in the locking platform assembly. The operation is very simple.
[0030] In some embodiments, such as Figures 2-7 As shown, the locking mechanism 3 includes a housing 31 and a locking mechanism disposed inside the housing 31. The locking mechanism is used to lock the locking rod 24 on the lock body assembly 2. The locking mechanism includes an elastic body 32, a bracket 33, and an upper limit cap 34 slidably sleeved on the bracket 33. The elastic body 32 is also a spring or an elastic structure with telescopic return. The elastic body 32 is disposed at the bottom of the bracket 33 and elastically abuts against the bracket 33. The bracket 33 and the three circular balls 35 are made of materials with magnetic attraction. When the unlocking magnet unlocks the magnetic lock, under the strong magnetic attraction of the magnet, the bracket 33 and the three circular balls 35 slide towards the magnet, while the elastic body 32 is compressed and deformed. In this embodiment, the locking mechanism also includes a plastic sleeve. The upper limit cap 34 is fixedly installed inside the plastic sleeve. When the magnetic lock is unlocked, the upper limit cap 34 remains fixed. The upper limit cap 34 is a hollow structure that is smaller at the top and larger at the bottom. The top of the upper limit cap 34 is open. The bracket 33 has a through hole and is a hollow structure. A partition layer 331 is located near the center of the bracket 33. At least three clearance holes 332 penetrating the outer wall of the bracket 33 are provided on the bracket 33 above the partition layer 331. A through hole is provided at the top of the bracket 33, corresponding to the through hole on the limiting cap 34. The locking mechanism also includes at least three circular balls 35, all of which are movably disposed inside the bracket 33 and located within the partition layer 332. Above 31, three circular balls 35 are arranged in a one-to-one correspondence with the clearance holes 332. A locking hole 351 is formed at the center of the three circular balls 35. The locking hole 351 is arranged in a corresponding manner with the locking rod 24. The opening diameter of the locking hole 351 in the initial state is smaller than the diameter of the locking rod 24. When the cylindrical button rod 21 is pressed, the locking rod 24 on the cylindrical button rod 21 passes through the through hole and the through hole and is locked into the locking hole 351, forming a locking state for the locking rod 24, and at the same time forming a top and bottom fixation of the opening of the bag body 1.
[0031] Working principle:
[0032] When the user places a mobile phone or other items into the storage cavity of the bag body 1, pressing the cylindrical button rod 21 causes the cylindrical button rod 21 and rod section 23 to slide and retract into the base 22. The locking rod 24 on the cylindrical button rod 21 passes through the through hole on the limiting cap 34 and the through hole on the bracket, reaching the locking hole 351 formed by the three circular balls 35. Since the opening diameter of the locking hole 351 is smaller than the diameter of the locking rod 24, the locking rod 24 compresses the three circular balls 35. The three circular balls 35 are subjected to the compressive force, and the bracket 33 slides downward in sync, compressing and deforming the elastic body 22. Since the limiting cap 34 is a hollow structure with a smaller top and a larger bottom, when the bracket 33 slides to the point where the opening diameter of the locking hole 351 formed by the three circular balls 35 is larger than the locking rod 24, the locking rod 24 passes through the locking hole 351. At this time, the cylindrical button rod 21 is released. Under the reset force of the elastic body 32, the button lever 21 pushes the bracket 33 upward, and at the same time, the opening of the lock hole 351 formed by the three circular balls 35 narrows and tightly presses against the locking rod 24 that has been clamped through, completing the locking state. At the same time, it fixes the upper edge 11 and the lower edge of the bag opening of the bag body 1. If the user needs to unlock, he only needs to align the unlocking strong magnet with the bottom of the lock platform assembly 3. Under the strong magnetic attraction, the three circular balls 35 and the bracket 33 slide along the limit cap 34 in the direction of magnetic attraction. The opening of the lock hole 351 of the three circular balls 35 becomes larger, releasing the clamping and locking of the locking rod 24. At the same time, under the reset force of the elastic body 25, the cylindrical button lever 21 and the lever section 23 automatically pull out the locking rod 24 inserted in the lock hole 351, and the unlocking is completed. The operation is very simple.
[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
