In the ever-evolving application environment, the space available for locks is constantly shrinking; existing locks occupy a large space and have a long operating stroke, making it difficult to meet actual needs. Utility Model Content

[0003] To address the problems existing in the prior art, this application provides a 90-degree rotating clamping lock, which reduces the size of the lock body, decreases the operating space, and shortens the operating stroke while ensuring the function of the lock, so as to adapt to the operation of the clamping lock in a small space.

[0004] The 90-degree rotating clamping lock provided in this application adopts the following technical solution.

[0005] A 90-degree rotating clamping lock includes: a lock body, a lock cylinder, a guide sleeve, a lock shaft, a drive pin, a spring, and a lock tongue;

[0006] The guide sleeve is fixedly installed in the lock body, and a rotating guide groove is provided on the guide sleeve. The rotating guide groove includes a spiral groove and a locking groove, and the locking groove is located at the end of the spiral groove.

[0007] The lock cylinder is located inside the lock body, and the guide sleeve is fitted on the lock cylinder. The lock cylinder is fixed axially and rotated circumferentially. One end of the lock cylinder is provided with a mating part that cooperates with the key, and the other end of the lock cylinder is provided with a lock shaft hole. A radial guide groove communicating with the lock shaft hole is provided on the lock cylinder along the axial direction.

[0008] One end of the locking shaft is slidably disposed in the locking shaft hole, and a spring is pre-tightly disposed between one end of the locking shaft and the locking shaft hole. A drive pin hole for placing the drive pin is opened radially on the locking shaft. The end of the drive pin passes through the radial guide groove and is inserted into the rotary guide groove. The drive pin can rotate ninety degrees along the rotary guide groove.

[0009] The locking tongue is located at the other end of the locking shaft.

[0010] By adopting the above technical solution, when the key rotates the lock cylinder, it drives the drive pin and lock shaft to rotate. This causes the drive pin to rotate 90 degrees along the rotation guide groove. Under the helical lead of the helical groove, the lock shaft simultaneously rotates axially, causing the bolt to swing and move closer to or away from the lock body. When opening, turning the key 90 degrees causes the lock cylinder to rotate the bolt 90 degrees, while the lock shaft extends away from the lock body. When locking, the action is the opposite of opening. When the drive pin moves to the locking groove, the bolt stops rotating, achieving a tight lock. Under the spring force, the extension trend of the lock shaft and drive pin is maintained, ensuring the engagement of the drive pin and the locking groove, maintaining a stable closed state. This technical solution only requires rotating the key 90 degrees to lock or unlock, significantly reducing the operational stroke and minimizing the space occupied by the lock, making it more suitable for use in small spaces.

[0011] Optionally, the lock body is provided with a flange, and a washer and a nut are installed on the lock body.

[0012] By adopting the above technical solution, and through the setting of flanges, washers and nuts, the lock body of this application is facilitated to connect with the door body, realizing convenient connection and fixation with the door panel, and improving the ease of installation of the lock in this application.

[0013] Optionally, the other end of the lock body is provided with an inner edge, the other end of the guide sleeve abuts against the inner edge of the lock body, the lock cylinder is provided with a lock cylinder shoulder, the other end of the lock cylinder is inserted into the guide sleeve, the lock cylinder shoulder abuts against one end of the guide sleeve, and the other end of the lock cylinder is provided with a retaining spring.

[0014] By adopting the above technical solution, the axial fixed connection between the lock cylinder and the guide sleeve and the lock body is achieved through the setting of the inner edge, lock cylinder shoulder and snap ring, and the final assembly is completed by snap ring. This method is simple to operate, easy to install and disassemble, and the assembly is stable and reliable.

[0015] Optionally, the other end of the lock body is provided with a limiting rotation protrusion, and the other end of the guide sleeve is provided with a limiting rotation groove that cooperates with the limiting rotation protrusion.

[0016] By adopting the above technical solution, the rotation between the guide sleeve and the lock body is restricted through the cooperation of the rotation limiting protrusion and the rotation limiting groove, thereby achieving the positioning of the guide sleeve.

[0017] Optionally, a sealing ring groove is provided on the shoulder of the lock cylinder, and a sealing ring is provided in the sealing ring groove.

[0018] By adopting the above technical solution, the sealing ring, in conjunction with the lock body and lock cylinder, ensures the lock's protection level and provides excellent shock resistance.

[0019] Optionally, two radial guide grooves are provided symmetrically along the axis, two rotary guide grooves are provided symmetrically along the axis, the locking groove is located at one end of the spiral groove, and both ends of the drive pin pass through the radial guide groove and are inserted into the rotary guide groove.

[0020] Optionally, the other end of the lock shaft is a rectangular connecting part, and a rectangular connecting hole is provided corresponding to the inner end of the lock tongue. The outer end of the lock tongue is bent away from the lock shaft, and the side edge of the outer end of the lock tongue is folded away from the lock shaft.

[0021] By adopting the above technical solution, the connection between the bolt and the locking shaft is simple and reliable, ensuring that the bolt rotates synchronously when the locking shaft rotates.

[0025] Optionally, the locking shaft and the locking tongue are connected by screws.

[0026] By adopting the above technical solution, the screw connection method is simple and reliable.

[0027] In summary, this application includes at least the following beneficial effects:

[0028] 1. In this application, when the key is rotated to turn the lock cylinder, it drives the drive pin and lock shaft to rotate. This causes the drive pin to rotate 90 degrees along the rotation guide groove. Under the helical lead of the helical groove, the lock shaft simultaneously rotates axially, causing the bolt to swing and move closer to or away from the lock body. When opening, the key turns 90 degrees, causing the lock cylinder to rotate 90 degrees, while the lock shaft extends away from the lock body. When locking, the action is the reverse of the opening process. When the drive pin moves to the locking groove, the bolt stops rotating, achieving closure. Under the elastic force of the spring, the extension trend of the lock shaft and drive pin is maintained, ensuring the cooperation between the drive pin and the locking groove, maintaining a stable closed state. The technical solution of this application only requires rotating the key 90 degrees to complete locking or unlocking, significantly reducing the operating stroke and minimizing the space occupied by the lock, making it more suitable for use in small spaces.

[0055] The working principle of a 90-degree rotating clamping lock disclosed in this embodiment is as follows:

[0056] When the key is turned to rotate the lock cylinder 3, it drives the drive pin 6 and the lock shaft 4 to rotate. This causes the drive pin 6 to rotate 90 degrees along the rotation guide groove. Under the helical guidance of the helical groove 201, it simultaneously drives the lock shaft 4 to rotate axially, causing the bolt 7 to swing as it approaches or moves away from the lock body 1. When opening, turning the key 90 degrees causes the lock cylinder 3 to rotate the bolt 7 90 degrees, while the lock shaft 4 extends away from the lock body 1. When locking, the action is the opposite of opening. When the drive pin 6 moves to the locking groove 202, the bolt 7 stops rotating, achieving a tight lock. Under the elastic force of the spring 5, the extension trend of the lock shaft 4 and drive pin 6 is maintained, ensuring the engagement of the drive pin 6 with the locking groove 202 and maintaining a stable closed state. The technical solution of this application only requires rotating the key 90 degrees to complete locking or unlocking, significantly reducing the operating stroke and minimizing the space occupied by the lock, making it more suitable for use in small spaces.
