Description

Technical Field

[0001] This utility model relates to the technical field of door locks, specifically a handle lock. Background Technology

[0002] Handle locks are widely used in door and window handles. A door lock system usually consists of three parts: the handle lock, the lock body, and the latch. The handle lock serves as the operating interface of the lock body. It is usually driven by rotating or pushing to make the bolt and the latch work together to lock or unlock the door.

[0003] In existing technologies, the connection between the handle lock and the bolt is not stable enough. With prolonged use, the stability between the bolt and the lock body will decrease, thus failing to provide a stable locking effect. Some handle locks have a relatively complex structure, which makes maintenance difficult for operators after prolonged use, thereby affecting the performance.

[0004] In order to simplify the structure of the handle lock, provide a more stable connection, and simplify the operation of opening or closing the lock body for the operator, so as to facilitate the operator to carry out corresponding inspection and maintenance. Utility Model Content

In this embodiment, the locking groove 311 is located in the middle of the adjustment groove 312, and the inner cavities of the locking groove 311 and the adjustment groove 312 are connected. The first locking nut 32 is threadedly connected to the threaded section of the connecting part 31. The snap-fit ​​piece 33 is sleeved on the threaded section of the connecting part 31, and the snap-fit ​​piece 33 is clamped between the first locking nut 32 and the mounting plate 11.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The edges of both the locking groove 311 and the adjusting groove 312 are rounded.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The locking device 3 also includes an extension rod 34, a fixing ring 35, a spring 36, and a fixing block 37. In this embodiment, the outer wall of the extension rod 34 is provided with a threaded section. The extension rod 34 passes through the connecting part 31 and is coaxially fixedly connected to the support rod 22. The fixing ring 35 is sleeved on the extension rod 34, and the fixing ring 35 and the extension rod 34 are coaxially fixedly connected. The spring 36 is sleeved on the extension rod 34, and the two ends of the spring 36 abut against the connecting part 31 and the fixing ring 35 respectively. The fixing block 37 is fixed to the outer wall of the fixing ring 35.

[0031] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, when the first end face abuts against the mounting ring 21, the fixing block 37 is located in the locking groove 311, and when the second end face abuts against the mounting ring 21, the fixing block 37 is located in the adjusting groove 312.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The locking device 3 also includes a locking plate 38, which has a through groove for accommodating the extension rod 34, and the locking plate 38 can slide along the axial direction of the extension rod 34.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The locking device 3 also includes two locking components 39, which are located above and below the surface of the locking plate 38, respectively. Each locking component 39 includes a locking plate 391 and a second locking nut 392. The two locking plates 391 are attached to the top and bottom walls of the locking plate 38, and the second locking nut 392 is located on the side of the locking plate 391 away from the locking plate 38. The second locking nut 392 is threadedly connected to the extension rod 34.

[0034] The implementation principle of a handle lock is as follows: the operator first fixes the mounting plate 11 to the corresponding position of the mounting structure using positioning bolts.

[0035] When the operator needs to unlock the handle lock, the operator rotates the contact part 242, which in turn drives the pin 232 of the support block 23 to rotate. At this time, the fixing block 37 is located outside the locking groove 311 and enters the adjusting groove 312. Then, the support block 23 is rotated, which causes the fixing block 37 to rotate along the adjusting groove 312, thereby driving the extension rod 34 to rotate and the locking plate 38 to rotate, thus realizing the function of the handle lock.

[0036] When the operator needs to close the handle lock, the operator only needs to rotate the support block 23, thereby placing the fixing block 37 in the locking groove. At this time, the fixing block 37 is limited by both sides of the locking groove 311, so that the extension rod 34 cannot rotate, thereby controlling the locking plate 38 to not rotate, thus realizing the locking function of the handle lock.
