[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: Figures 1 to 2 As shown, this embodiment discloses a door lock, including as follows: Figures 3 to 7The quick-release connection structure and square core 4 of the door lock shown are included. The quick-release connection structure includes a door handle housing 1, an unlocking component 3, and a rotating assembly 2 disposed inside the door handle housing 1. The door handle housing 1 is provided with a connecting post 111 located at one end of the door handle housing 1. One end of the unlocking component 3 passes through the connecting post 111, and the other end extends to be provided with a fixing plate 31. The fixing plate 31 cooperates with the connecting post 111 to restrict the axial movement of the unlocking component 3. The rotating assembly 2 includes a first rotating post 21 detachably disposed inside the door handle housing 1 and capable of rotating relative to the door handle housing 1. The front end of the first rotating post 21 is provided with a fixing groove 211, and the fixing plate 31 cooperates with the fixing groove 211 for fixation. With the structure of this utility model, since the first rotating column is installed inside the door handle housing, and the lower housing 11 is provided with a connecting column 111, and a fixing plate extends from one end of the unlocking component, when it is necessary to connect the unlocking component to the first rotating column, only one end of the unlocking component needs to pass through the connecting column, and the other end cooperates with the fixing groove. Since the cooperation between the fixing plate and the connecting column can restrict the axial movement of the unlocking component, and the cooperation between the fixing groove and the fixing plate can restrict the rotation of the unlocking component, the unlocking component can be quickly connected and fixed to the transmission assembly. The square core 4 is sleeved on the unlocking component 3, and the rear end of the square core 4 is connected to the connecting column 111. The door lock includes a lock body 6 for locking, the lock body 6 includes an unlocking groove 61 and an unlocking hole 62, the unlocking groove 61 is fixedly connected to the front end of the square core 4, and the unlocking component 3 penetrates the unlocking hole 2. The unlocking component 3 penetrates the unlocking hole 62, and the unlocking groove 61 cooperates with the square core 4. When unlocking is required, the key is inserted into the lock cylinder 5 and turned, causing the second rotating column 22 to rotate, which in turn drives the first rotating column 21 to rotate. The unlocking component 3 unlocks the lock body 6 through the unlocking hole 62, the square core 5 is inserted into the unlocking groove 61, and then the door handle housing 1 is pressed down, causing the square core 4 to rotate and unlock the lock body 6.
[0026] As a specific embodiment and not a limitation, in order to better install the unlocking component 3 within the fixing groove 211 and restrict the axial rotation of the unlocking component 3, a limiting block 2111 is provided within the fixing groove 211. The side wall of the first rotating column 21 has an installation port 212 communicating with the fixing groove 211. The fixing plate 31 enters the fixing groove 211 by engaging with the installation port 212. The limiting block 2111 abuts against the fixing plate 31 to restrict the circumferential rotation of the unlocking component 3 relative to the first rotating column 21. By abutting the fixing plate 31 of the unlocking component against the limiting block 2111 located inside the fixing groove 211, the axial rotation of the unlocking component 3 is restricted. Furthermore, by using the installation port 212 communicating with the fixing groove 211 on the side wall of the first rotating column 21, the fixing plate 31 is aligned with the installation port 212 during the installation of the unlocking component 3, allowing the fixing plate 31 to enter the fixing groove through the installation port 212, thus achieving rapid installation.
[0027] Furthermore, to ensure the first rotating column 21 can rotate more stably within the door handle housing 1, the door handle housing 1 includes a lower housing 11. The lower housing 11 is provided with a first baffle 112 and a second baffle 113, forming an installation gap 114 between the first baffle 112 and the second baffle 113. The first rotating column 21 is provided with a baffle 213, which is disposed on the installation gap 114. Because of the installation gap 114 between the first baffle 112 and the second baffle 113, and the baffle 213 on the first rotating column 21 being disposed on the installation gap 114, the baffle 213 can rotate well within the installation gap 114. The first baffle 112 and the second baffle 113 cooperate to restrict the axial movement of the first rotating column 21, making the first rotating column 21 rotate more smoothly within the door handle housing.
[0028] Furthermore, the rear end of the baffle 213 is provided with a limiting rib 214, which cooperates with the second baffle 113 to restrict the rotation of the first rotating column 21. When the first rotating column 21 rotates to the point where the limiting rib 214 abuts against the second baffle, the first rotating column 21 will stop rotating. At this time, the opening of the mounting port 212 is located at the bottom or top of the lower housing 11. When the opening of the mounting port 212 is at the bottom, the unlocking member 3 is twisted so that the fixing plate 31 is aligned with the mounting port 212. At this time, the first rotating column 21 can be removed from the lower housing 21, thus completing the disassembly of the unlocking member 3.
[0029] As a specific real-time method rather than a limitation, since the door handle housing 1 is bent and the lock cylinder 5 is located at the rear end of the door handle housing, in order to adapt to the door handle housing 1, the rotating assembly 2 includes a lock cylinder 5 located inside the door handle housing 1. The rotating assembly 2 also includes a second rotating column 22 detachably located inside the door handle housing 1 and rotatable relative to the door handle housing 1. One end of the first rotating column 21 is provided with a first bevel gear 215, and one end of the second rotating column 22 is provided with a second bevel gear 221. The first bevel gear 215 and the second bevel gear 221 mesh, and the second rotating column 22 is connected to the lock cylinder 5. The first bevel gear 215 and the second bevel gear 221 located on the first rotating column 21 mesh. When the key is inserted into the lock cylinder 5 and turned, the second rotating column 22 rotates, the first bevel gear 215 and the second bevel gear 221 mesh, and the first rotating column 21 and the second rotating column 22 are perpendicular. When the second rotating column 22 rotates, the first rotating column 21 rotates together, and the unlocking component 3 rotates together.
[0030] Furthermore, to facilitate quick installation of the lower housing 11 and the upper housing 12, the door handle housing 1 also includes an upper housing 12. The lower housing 11 has a mounting groove 115 along its circumference, and the upper housing 12 has a mounting protrusion 121 for engaging and fixing with the mounting groove 115. The mounting groove 115 and the mounting protrusion 121 are interference-fitted to install and fix the lower housing 11 and the upper housing 12.
[0031] The specific working principle of this embodiment is as follows:
[0032] By setting a rotating assembly inside the door handle housing, the rotating assembly includes a first rotating column, a fixing groove on the first rotating column, and an installation port on the first rotating column and communicating with the fixing groove. A fixing plate extends from the unlocking component. When the unlocking component needs to be installed on the first rotating column, the unlocking component first penetrates the connecting column, and then the fixing plate on the unlocking component cooperates with the installation port to pass through the installation port and enter the fixing groove. A limiting block is set inside the fixing groove to restrict the rotation of the fixing plate in the fixing groove. The connecting column cooperates with the fixing plate to restrict the axial movement of the unlocking component. By setting the baffle on the installation gap to restrict the axial movement of the first rotating column, the unlocking component can be quickly installed on the first rotating column.
[0033] When it is necessary to remove the unlocking component from the first rotating column, the first rotating column needs to be rotated so that the mounting port on the rotating column is aligned with the lower housing. Then, by rotating the unlocking component, the fixing plate is aligned with the mounting port. At this point, the first rotating column can be removed from the lower housing to complete the removal of the unlocking component.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
