DETAILED DESCRIPTION

[0033] In order to better understand the purpose, structure and function of the utility model, a lock structure and a lock of the utility model are further described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1 As shown, it shows a lock structure of an embodiment of the utility model, including a fixing seat 1, a mounting hole extending from the upper part to the lower end is arranged in the fixing seat 1, and a transmission mechanism 2 is arranged in the mounting hole of the fixing seat 1. In the process of installing the magnetic lock body 5 into the fixing seat 1 from the mounting hole, the magnetic lock body 5 can generate an upward force on the transmission mechanism 2, and the transmission mechanism 2 can convert the upward force of the magnetic lock body 5 it receives into a clamping force on the magnetic lock body 5, so as to clamp the magnetic lock body 5; the transmission mechanism 2 is connected to a fixing mechanism 4, and the fixing mechanism 4 is used to fix the transmission mechanism 2 on the fixing seat 1 after the transmission mechanism 2 clamps the magnetic lock body 5.

[0035] In actual use, the fixing base 1 of the lock structure of this embodiment is fixed on the wall above the door body, and the magnetic lock body 5 is used to cooperate with the corresponding structure on the door body to lock or open the door. This embodiment improves the loosening of the magnetic lock in the prior art.

[0036] In the present embodiment, a mounting hole extending from the upper part to the lower end is provided in the fixing base 1 , and the mounting hole is provided for allowing the magnetic lock body 5 to be installed into the fixing base 1 through the mounting hole.

[0037] The transmission mechanism 2 is located in the fixing seat 1. When the magnetic lock body 5 is installed upward from the mounting hole into the fixing seat 1, the magnetic lock body 5 and the transmission mechanism 2 come into contact with each other and the magnetic lock body 5 accordingly generates an upward force on the transmission mechanism 2. The transmission mechanism 2 converts the upward force of the magnetic lock body 5 into a clamping force on the magnetic lock body 5. The transmission mechanism 2 can clamp the magnetic lock body 5 through the clamping force.

[0038] The transmission mechanism 2 of this embodiment is connected to a fixing mechanism 4 , and the fixing mechanism 4 is used to fix the transmission mechanism 2 on the fixing seat 1 after the transmission mechanism 2 clamps the magnetic lock body 5 , thereby fixing the magnetic lock body 5 .

[0039] In one embodiment, if Figure 2-3 As shown, the transmission mechanism 2 includes a movable plate 202, which is located at the upper end of the magnetic lock body 5, and the movable plate 202 can contact the magnetic lock body 5 moving upward, and the left and right sides of the movable plate 202 are respectively rotatably connected to one end of the connecting rod 205, and the other end of each connecting rod 205 is respectively rotatably connected to a moving block 206, and a horizontal sliding groove 102 cooperating with each moving block 206 is provided on the front side wall and / or the rear side wall of the mounting hole, and the two moving blocks 206 are used to cooperate with the left and right side walls of the magnetic lock body 5 to clamp the magnetic lock body 5; the fixing mechanism 4 is connected to the movable plate 202, and the fixing mechanism 4 is used to fix the movable plate 202 on the fixing seat 1 after the transmission mechanism 2 clamps the magnetic lock body 5.

[0040] In this embodiment, the transmission mechanism 2 includes a movable plate 202, a connecting rod 205 and a moving block 206. The movable plate 202 is located above the magnetic lock body 5, and the movable plate 202 can contact the magnetic lock body 5 moving upward. Therefore, in the process of installing the magnetic lock body 5 upward from the mounting hole into the fixing seat 1, the magnetic lock body 5 will contact the movable plate 202. After the magnetic lock body 5 contacts the movable plate 202, the magnetic lock body 5 will push the movable plate 202 to move upward.

[0041] The movable plate 202 and the two moving blocks 206 are connected by a connecting rod 205. A horizontal slide groove 102 cooperating with each moving block 206 is provided on the front side wall and / or the rear side wall of the mounting hole. The setting of the horizontal slide groove 102 enables the two moving blocks 206 to move only in the horizontal slide groove 102. The two moving blocks 206 are used to cooperate with the left and right side walls of the magnetic lock body 5. Therefore, when the two moving blocks 206 are close to each other, the magnetic lock body 5 can be clamped by the two moving blocks 206. In combination with the upward movement of the movable plate 202, the movable plate 202 moves upward and drives the two moving blocks 206 to approach each other along the horizontal slide groove 102 through the two connecting rods 205. The two moving blocks 206 move close to each other to gradually clamp the magnetic lock body 5.

[0042] The aforementioned fixing mechanism 4 is connected to the movable plate 202 to fix the movable plate 202 on the fixed seat 1. After the movable plate 202 moves to the two moving blocks 206 to clamp the magnetic lock body 5, the fixing mechanism 4 fixes the movable plate 202 on the fixed seat 1. After the movable plate 202 is fixed on the fixed seat 1, the movable plate 202 cannot move, so the two moving blocks 206 are always in a state of clamping the magnetic lock body 5, that is, the purpose of fixing the magnetic lock body 5 in the fixed seat 1 is achieved.

[0043] In this embodiment, the magnetic lock body 5 is clamped by two moving blocks 206, and the two moving blocks 206 are fixed because the movable plate 202 is fixed by the fixing mechanism 4, thereby achieving the clamping of the magnetic lock body 5. The magnetic lock body 5 of this embodiment can be clamped more firmly between the two moving blocks 206, which improves the loosening of the magnetic lock compared to the prior art.

[0044] In one embodiment, if Figure 2 , Figure 4 As shown, the fixing mechanism 4 includes an L-shaped clamping block 401, one end of which is fixedly connected to the movable plate 202, a notch is provided on the front side wall of the fixing seat 1 for the other end of the clamping block 401 to extend out of the mounting hole, a cylindrical hole is provided on the other end of the clamping block 401, and the axial direction of the cylindrical hole is perpendicular to the front side wall of the fixing seat 1; a latch 402 and a connecting spring 403 are provided in the cylindrical hole, one end of the connecting spring 403 is fixedly connected to the latch 402, and the other end of the connecting spring 403 is fixedly connected to the clamping block 401, a plug-in hole 204 is provided on the front side wall of the fixing seat 1, the connecting spring 403 is configured to enable the latch 402 to be inserted into the plug-in hole 204, and when the two moving blocks 206 clamp the magnetic lock body 5, the latch 402 is inserted into the plug-in hole 204.

[0045] In this embodiment, the fixing mechanism 4 includes an L-shaped clamping block 401, one end of which is fixedly connected to the movable plate 202, so that when the movable plate 202 moves upward, the clamping block 401 moves upward accordingly. The notch on the front side wall of the fixing seat 1 is provided to allow the clamping block 401 to extend out of the mounting hole, and the notch penetrates the front side wall of the fixing seat 1 to communicate with the mounting hole.

[0046] A cylindrical hole is provided at the other end of the clamping block 401, and a latch 402 and a connecting spring 403 are arranged in the cylindrical hole. The connecting spring 403 is sleeved on the latch 402, and the latch 402 cooperates with the plug hole 204 on the fixing seat 1. The connecting spring 403 is configured to enable the latch 402 to be inserted into the corresponding plug hole 204. Therefore, the movable plate 202 can be fixed on the fixing seat 1 by setting the connecting spring 403, the latch 402 and the corresponding plug hole 204. The position of the plug hole 204 in this embodiment also needs to cooperate with the transmission mechanism 2, that is, the two moving blocks 206 clamp the magnetic lock body 5. When the movable block cannot move up, the latch 402 is just inserted into the plug hole 204.

[0047] The end surface of the latch pin 402 close to the fixing base 1 is an inclined surface 4021 , and a vertical row of plug holes 204 is formed on the front side wall of the fixing base 1 .

[0048] The arrangement of the vertical row of plug holes 204 in this embodiment can facilitate the use of magnetic lock bodies 5 of different models.

[0049] The end surface of the latch 402 close to the fixed seat 1 is an inclined surface 4021. The setting of the inclined surface 4021 can facilitate the latch 402 to disengage from the plug-in hole 204 during the process of moving upward with the clamping block 401. Therefore, when the movable plate 202 moves upward with the magnetic lock body 5, the fixing mechanism 4 can move upward accordingly; when the movable plate 202 moves to the movable block 206 that has clamped the magnetic lock body 5 and the movable plate 202 cannot move further upward, the latch 402 is inserted into the corresponding plug-in hole 204 again under the action of the connecting spring 403, thereby achieving the purpose of fixing the movable plate 202 on the fixed seat 1 through the fixing mechanism 4 after the movable block 206 clamps the magnetic lock body 5.

[0050] In one embodiment, if Figure 2 As shown, a baffle 203 is fixedly connected to the upper end of the clamping block 401 , and the baffle 203 is used to prevent dust from entering the fixing base 1 through the slot.

[0051] The baffle plate 203 of this embodiment plays a certain role in blocking dust. In specific implementation, the baffle plate 203 can be arranged to be attached to the side wall of the mounting hole, or to be attached to the outer side wall of the fixing base 1.

[0052] In one embodiment, if Figure 3 As shown, a vertical slide groove 101 is provided on the rear side wall of the mounting hole, and a sliding block 201 is fixedly connected to the rear side of the movable plate 202, and the sliding block 201 is located in the vertical slide groove 101. The vertical slide groove 101 of this embodiment is used to limit the movement of the movable plate 202, so that the movable plate 202 can only move up and down along the vertical slide groove 101.

[0053] Among them, each moving block 206 is fixedly connected with a matching block 2061 on one side close to another moving block 206, and the left and right side walls of the magnetic lock body 5 are fixedly connected with connecting blocks 208 respectively, and each connecting block 208 is provided with a matching groove 2081 that matches with the matching block 2061.

[0054] In this embodiment, the moving block 206 cooperates with the matching groove 2081 on the magnetic lock body 5 through the matching block 2061 to achieve the purpose of clamping the magnetic lock body 5. Specifically, in the process of inserting the magnetic lock body 5 upward through the installation hole, the magnetic lock body 5 moves upward to push the movable plate 202 to move upward, and the movable plate 202 moves upward to make the two moving blocks 206 approach each other. When the matching blocks 2061 of the two moving blocks 206 are respectively stuck in the corresponding matching grooves 2081, the magnetic lock body 5 is clamped.

[0055] In one embodiment, if Figure 3 As shown, the front and rear ends on the left side of the movable plate 202 and the front and rear ends on the right side of the movable plate 202 are respectively rotatably connected to one end of a connecting rod 205, and the other end of each connecting rod 205 is respectively rotatably connected to the corresponding moving block 206; the upper end of the magnetic lock body 5 and / or the lower end of the movable plate 202 are fixedly connected with an extrusion block 207.

[0056] In this embodiment, the movable plate 202 is rotatably connected to four connecting rods 205, which are respectively located at the left and right ends of the front side of the movable plate 202 and the left and right ends of the rear side of the movable plate 202, so that the movement of the movable plate 202 can be more stable.

[0057] The squeezing block 207 of this embodiment is provided to ensure that the magnetic lock body 5 can contact with the movable plate 202 during the process of being installed upward from the mounting hole.

[0058] In one embodiment, if Figure 1 , Figure 3 As shown, a buffer mechanism 3 is connected to the lower end of the fixing seat 1, and the buffer mechanism 3 is used to reduce the closing speed of the corresponding door body.

[0059] The buffer mechanism 3 of this embodiment is used to reduce the closing speed of the door body, thereby reducing the impact force between the magnetic lock body 5 and the door body during the closing process of the door body, and increasing the service life of the lock body.

[0060] In specific implementation, for the case where there are two doors, buffer mechanisms 3 are provided on both sides of the fixed seat 1 to reduce the closing speed of the two doors; for the case where there is only one door, a buffer mechanism 3 is provided on one side of the fixed seat 1.

[0061] In one embodiment, if Figure 5As shown, the buffer mechanism 3 includes a fixed block 305, which is fixed to the lower end of the fixed seat 1. The fixed block 305 is fixedly connected to a positioning rod 302 near the front side of the door body. A sliding groove is provided in the positioning rod 302, and the axial direction of the sliding groove is perpendicular to the front side wall of the fixed seat 1; a moving rod 303 is slidably connected in the sliding groove, and one end of the moving rod 303 away from the fixed block 305 extends out of the sliding groove and is fixedly connected to the corresponding support block 301, and one end of the moving rod 303 located in the sliding groove is fixedly connected to a limiting block 3031, and the fixed rod is close to the support block 301. One end of the support block 301 is fixedly connected to a baffle ring 3021, and the baffle ring 3021 cooperates with the limit block 3031 to make the limit block 3031 located in the sliding groove; a buffer spring 304 is arranged between the bottom wall of the sliding groove and the limit block 3031 in the sliding groove, and the buffer spring 304 is configured to make the limit block 3031 press on the baffle ring 3021, and / or, the bottom wall of the sliding groove and the limit block 3031 in the sliding groove are filled with damping fluid; when the limit block 3031 is pressed on the baffle ring 3021, the support block 301 can contact the door body that has not yet been closed.

[0062] In this embodiment, when the limit block 3031 is pressed on the retaining ring 3021, the support block 301 can contact the door body that has not yet been closed. Therefore, during the closing process of the door body, the door body will contact the support block 301. After the support block 301 contacts the door body, the door body continues to close and needs to overcome the damping effect of the buffer spring 304 and / or the damping fluid, thereby achieving the purpose of reducing the closing speed of the door body.

[0063] In a specific implementation, by adjusting the overall length of the moving rod 303 and the positioning rod 302 , it is possible to achieve the purpose that when the limit block 3031 is pressed on the retaining ring 3021 , the support block 301 can be in contact with the door body that has not yet been closed.

[0064] The sliding groove of this embodiment is used to guide the movement of the moving rod 303; the retaining ring 3021 cooperates with the limiting block 3031 to limit the limiting block 3031 in the sliding groove.

[0065] The buffer spring 304 and / or damping fluid are provided to reduce the closing speed of the door body, and after the door body is opened, the moving rod 303 can be reset to the limit block 3031 pressing on the retaining ring 3021 under the action of the buffer spring 304 and / or damping fluid.

[0066] In one embodiment, if Figure 3 , Figure 5 As shown, the upper end of the support block 301 is fixedly connected to a guide block 3011 , and the lower end of the fixing seat 1 is provided with a guide groove 103 that cooperates with the guide block 3011 .

[0067] In specific use, when the relevant personnel need to install the magnetic lock body 5, the magnetic lock body 5 is installed into the fixed seat 1 through the installation hole, and the magnetic lock body 5 is pushed upward so that the extrusion block 207 of the magnetic lock body 5 pushes the movable plate 202 upward. The movable plate 202 moves upward to drive the connecting rods 205 on both sides to move, thereby making the two movable blocks 206 approach each other; at the same time, when the movable plate 202 moves upward, it will drive the clamping block 401 to move upward, so that the latch 402 gradually withdraws from the plug-in hole 204 through its inclined surface 4021; as the movable plate 202 moves upward, when the matching block 2061 is inserted into the matching grooves 2081 on both sides of the magnetic lock body 5, the movable plate 202 cannot move upward. At this time, the connecting spring 403 enables the latch 402 to be inserted into the corresponding plug-in hole 204, thereby achieving the fixation of the movable plate 202.

[0068] When the door body is closed, the door body will first contact the support block 301, and during the closing process of the door body, the support block 301 is squeezed to make the support block 301 move accordingly. The support block 301 moves through the moving rod 303 to squeeze the buffer spring 304 and the damping fluid. The damping fluid will hinder the movement of the moving rod 303 due to its own properties. The buffer spring 304 is also configured to hinder the movement of the moving rod 303 approaching the fixed block 305. Therefore, the damping effect of the buffer spring 304 and the damping fluid will reduce the closing speed of the door body, reduce the impact force between the magnetic lock body 5 and the door body during the closing process of the door body, and thus increase the service life of the lock body.
