Description

Technical Field

[0001] This utility model relates to lock clutches, and more particularly to lock clutches with an inclined guide mounting structure. Background Technology

[0002] The lock clutch is a core component of smart locks and electronic locks, used to control the lock's engagement or disengagement state, thereby enabling the door to open or lock. Existing lock clutches include a lock housing, an outer connecting shaft, an inner connecting part, and a return spring. The return spring passes through the outer connecting shaft, and a stop block is located inside the lock housing. When the outer connecting shaft rotates, the return spring abuts against the stop block to store energy. After the external force is removed, it drives the outer connecting shaft to rotate and return to its original position. The stop block is square-shaped. Because the return spring passes through the outer connecting shaft and partially abuts against the stop block, and the stop block is square-shaped, it is difficult for the return spring to bypass the stop block and overlap it after passing through the outer connecting shaft. This makes the installation of the return spring inconvenient and inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide a lock clutch with an inclined guide installation structure to solve the problems of existing lock clutches where the return spring passes through the outer connecting shaft and partially abuts against the stop block, and the stop block is configured in a square shape, making it difficult for the return spring to bypass the stop block and overlap the stop block after passing through the outer connecting shaft, resulting in inconvenient installation and low installation efficiency of the return spring.

[0004] This utility model is achieved through the following technical solution:

[0005] A lock clutch with an inclined plane guide installation structure includes a lock housing, an outer connecting shaft, an inner connecting member, and a reset member. The lock housing has a receiving cavity. The outer connecting shaft and the inner connecting member are respectively disposed on the front and rear sides of the lock housing and can rotate relative to the lock housing. One end of the outer connecting shaft extends into the receiving cavity, and one end of the inner connecting member extends into the receiving cavity and is rotatably connected to the outer connecting shaft. When the outer connecting shaft rotates relative to the lock housing, it can push or release the inner connecting member. When the outer connecting shaft pushes the inner connecting member, it causes the inner connecting member to rotate synchronously with the outer connecting shaft. The reset member is mounted on the outer connecting shaft for driving the outer connecting shaft to move and reset. The cavity wall of the receiving cavity is provided with a stop block. The reset member has a stop rod for abutting against the stop block. The side of the stop block that abuts against the stop rod is defined as the stop surface. The side of the stop block opposite to the stop surface is provided with a guide surface. The guide surface is inclined towards the outer connecting shaft in a direction away from the stop rod.

[0006] Furthermore, a limiting block is provided on the abutting surface, which prevents the abutting rod from sliding away from the abutting surface when the abutting rod abuts against the abutting surface.

[0007] Furthermore, there are two abutting rods and two stop blocks, which correspond one-to-one. The two stop blocks are spaced apart to the left and right. Both stop blocks are provided with guide surfaces. One of the abutting rods abuts against the corresponding stop block when the outer connecting shaft rotates, while the other abutting rod rotates away from the corresponding stop block.

[0008] Furthermore, the outer connecting shaft is provided with a toggle member that rotates with it. The toggle member is provided with two left and right opposing toggle arms. The two toggle arms and the two stop rods correspond one to one. When the outer connecting shaft rotates, the stop rod is driven by the corresponding toggle arm to rotate in a direction away from the corresponding stop block.

[0009] Furthermore, the inner connector has an inner connecting shaft and an inner abutment block. The inner connecting shaft is rotatably connected to the outer connecting shaft. The inner abutment block extends circumferentially along the inner connecting shaft and is located below the two abutment rods. The two stop blocks are respectively disposed on the left and right sides of the inner abutment block and are located below the two abutment rods. The actuating member is disposed between the inner connector and the outer connecting shaft, and the two actuating arms are located below the two abutment rods.

[0010] Furthermore, the inner abutment block is provided with two actuating grooves, which are respectively located on the left and right sides of the inner connecting shaft. The actuating member is provided with an actuating block, which moves back and forth between the two actuating grooves when the outer connecting shaft rotates and can abut against either of the actuating grooves, so that the outer connecting shaft and the inner connecting member move synchronously.

[0011] Furthermore, the stop block and the lock housing are integrally formed.

[0012] Furthermore, the reset element is a torsion spring.

[0013] The advantage of this technical solution is that by configuring a stop block on the cavity wall, configuring a stop rod on the reset component to abut against the stop block, and configuring a guide surface on the side of the stop block opposite to the abutment surface, the abutment rod can slide along the guide surface to the abutment surface side after the reset component is inserted into the outer connecting shaft. The reset component is quick and convenient to install and has high installation efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-8As shown, the lock clutch with a sloped guide mounting structure includes a lock housing 1, an outer connecting shaft 2, an inner connecting member 3, and a reset member 4. The lock housing 1 has a receiving cavity 101. The outer connecting shaft 2 and the inner connecting member 3 are respectively located on the front and rear sides of the lock housing 1 and can rotate relative to the lock housing 1. One end of the outer connecting shaft 2 extends into the receiving cavity 101, and one end of the inner connecting member 3 extends into the receiving cavity 101 and is rotatably connected to the outer connecting shaft 2. When the outer connecting shaft 2 rotates relative to the lock housing 1, it can push or release the inner connecting member 3. When the outer connecting shaft 2 pushes the inner connecting member 3, it causes the inner connecting member 3 to... The resetting member 4 rotates synchronously with the outer connecting shaft 2 and is mounted on the outer connecting shaft 2 to drive the outer connecting shaft 2 to move and reset. The cavity wall of the receiving cavity 101 is provided with a stop block 102. The resetting member 4 has a stop rod 401 that abuts against the stop block 102. The side of the stop block 102 that abuts against the stop rod 401 is defined as the stop surface 104. The side of the stop block 102 facing away from the stop surface 104 is provided with a guide surface 103, which is inclined towards the outer connecting shaft 2 in a direction away from the stop rod 401. The outer connecting shaft 2 is connected to the outer door handle, and the inner connecting member 3 is connected to the inner door handle. The resetting member 4 is a torsion spring. When the outer connecting shaft 2 rotates, the stop rod 401 abuts against the stop block 102, allowing the resetting member 4 to store energy and drive the outer connecting shaft 2 to reset.

[0026] This embodiment provides a lock clutch with a sloping guide installation structure to solve the problems of existing lock clutches where the return spring passes through the outer connecting shaft and partially abuts against the stop block, and the stop block is configured in a block shape, making it difficult for the return spring to bypass the stop block and overlap it after passing through the outer connecting shaft, resulting in inconvenient installation and low installation efficiency. The solution is to configure the stop block 102 on the cavity wall of the receiving cavity 101, configure the abutment rod 401 on the return member 4 for abutting against the stop block 102, and configure the guide surface 103 on the side of the stop block 102 opposite to the abutment surface 104, so that after the return member 4 passes through the outer connecting shaft 2, the abutment rod 401 can slide along the guide surface 103 to the side of the abutment surface 104. The reset member 4 is quick and convenient to install, the installation efficiency is high, and the abutment rod 401 is not easily deformed or damaged.

[0027] In this embodiment of the invention, a limiting block 105 protrudes from the abutting surface 104. The limiting block 105 prevents the abutting rod 401 from sliding away from the abutting surface 104 when the abutting rod 401 abuts against the abutting surface 104. The above arrangement, by configuring the limiting block 105 on the abutting surface 104 to prevent the abutting rod 401 from sliding away from the abutting surface 104, ensures stable assembly between the limiting block 105 and the stop block 102, and avoids the abutting rod 401 sliding away from the abutting surface 104, which would cause the outer connecting shaft 2 to fail to reset.

[0028] In this embodiment of the invention, there are two abutment rods 401 and two stop blocks 102, each corresponding to the other. The two stop blocks 102 are spaced apart to the left and right, and each stop block 102 is provided with a guide surface 103. Of the two abutment rods 401, one abuts against the corresponding stop block 102 when the outer connecting shaft 2 rotates, while the other abutment rod 401 rotates away from the corresponding stop block 102. By configuring two abutment rods 401 and two stop blocks 102, the reset member 4 can store energy to drive the outer connecting shaft 2 to move and reset when the outer connecting shaft 2 rotates.

[0029] In this embodiment of the invention, an actuating member 5 is mounted on the outer connecting shaft 2 and rotates therewith. The actuating member 5 has two opposing actuating arms 501, which correspond one-to-one with two stop rods 401. When the outer connecting shaft 2 rotates, the stop rods 401 are driven by the corresponding actuating arms 501 to rotate away from the corresponding stop block 102. This arrangement, by configuring the actuating member 5 on the outer connecting shaft 2 and mounting the actuating arms 501 on the actuating member 5 to drive the stop rods 401 to rotate away from the corresponding stop block 102, ensures that when the outer connecting shaft 2 rotates, one stop rod 401 abuts against the corresponding stop block 102, while the other stop rod 401 rotates away from the corresponding stop block 102, thus achieving energy storage of the reset member 4.

[0030] In this embodiment of the invention, the inner connector 3 has an inner connecting shaft 301 and an inner abutment block 302. The inner connecting shaft 301 is rotatably connected to the outer connecting shaft 2. The inner abutment block 302 extends circumferentially along the inner connecting shaft 301 and is located below the two abutment rods 401. Two stop blocks 102 are respectively disposed on the left and right sides of the inner abutment block 302 and located below the two abutment rods 401. The actuating member 5 is disposed between the inner connector 3 and the outer connecting shaft 2, and two actuating arms 501 are located below the two abutment rods 401. The above arrangement, by placing the inner abutment block 302 below the two abutment rods 401, placing the two stop blocks 102 on the left and right sides of the inner abutment block 302 and located below the two abutment rods 401, and placing the two actuating arms 501 below the two abutment rods 401, makes the outer connecting shaft 2, inner connector 3, reset member 4, and actuating member 5 reasonably and compactly assembled.

[0031] In this embodiment of the utility model, the inner abutment block 302 is provided with two actuating grooves 303, which are respectively located on the left and right sides of the inner connecting shaft 301. The actuating member 5 is provided with a actuating block 502. When the outer connecting shaft 2 rotates, the actuating block 502 moves back and forth between the two actuating grooves 303 and can abut against either actuating groove 303, so that the outer connecting shaft 2 and the inner connecting member 3 move synchronously.

[0032] In this embodiment of the invention, the stop block 102 is integrally formed with the lock housing 1. This arrangement, by configuring the stop block 102 to be integrally formed with the lock housing 1, gives the stop block 102 good structural strength.
