Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a cabinet lock. Background Technology

[0002] A cabinet lock is a type of lock installed on door panels and other components. It primarily controls the opening and closing of the door by rotating a handle, which in turn rotates the bolt. Some modern locks also incorporate a lock cylinder, allowing for locking through the combined action of the handle and cylinder. Since locks are sometimes used in harsh environments with high levels of dust, a protective cover is typically installed to prevent dust from seeping into the lock cylinder and affecting its operation. However, with each opening and closing of the cover, its reliability can be compromised. After a period of use, the cover may no longer fit tightly against the lock cylinder, thus affecting the normal opening and closing of the lock. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cabinet lock.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cabinet lock includes a panel and a rotating shaft rotatably mounted on the panel. A handle is connected to the rotating shaft, and a lock cylinder is mounted on the handle. A ring sleeve and a fixing seat detachably mounted on the ring sleeve are provided on the inner side of the handle. A mounting bolt that passes through the inner circumference of the ring sleeve is threaded onto the fixing seat. A cover plate that covers the outer side of the lock cylinder and a spring that abuts against the inner side of the handle are fitted on the mounting bolt. The other end of the spring abuts against the abutment plate of the ring sleeve.

[0005] Preferably, a retaining spring is provided between the fixing seat and the abutment, which is engaged with the mounting bolt, and the retaining spring is located on the inner circumference of the ring.

[0006] Preferably, the cover plate is rotatably mounted on the mounting bolts, and the cover plate covers the lock hole of the lock cylinder.

[0007] Preferably, the rotating shaft is rotatably disposed within the base of the panel, the rotating shaft is provided with a protruding plate, and the base is provided with notches that allow the protruding plate to pass through and are distributed alternately with the protruding plate.

[0008] Preferably, a sealing ring is fitted around the outer periphery of the rotating shaft to abut against the base.

[0009] Preferably, the rotating shaft has a threaded hole, a fixing bolt for fixing the rotating shaft is connected to the threaded hole, and a locking tongue is installed between the rotating shaft and the fixing bolt.

[0010] Preferably, the panel has a groove for accommodating the handle.

[0011] Preferably, the panel is provided with a latch that passes through the handle, and a padlock can be installed on the latch.

[0012] The beneficial effects of this utility model are: 1. A mounting base can be detachably installed on the ring sleeve inside the handle. A mounting bolt that passes through the inner circumference of the ring sleeve is threaded onto the mounting base. When the mounting bolt is threaded onto the mounting base, the mounting bolt drives the cover plate to close onto the outside of the lock cylinder, thereby making the closing of the cover plate more reliable. When the mounting bolt is turned outward, the spring can push against the cover plate outward, so as to make it easier to rotate the cover plate. This makes it easier to rotate the cover plate to avoid the lock cylinder, and thus makes the opening operation of the lock more convenient. 2. A retaining spring is installed around the mounting bolts to limit the outward movement of the cover plate. The retaining spring abuts against the abutment plate to prevent the mounting bolts and cover plate from coming out of the handle, thus making the lock more reliable. 3. A convex plate is provided on the rotating shaft, and a notch is opened on the base for the convex plate to pass through. When installing the handle, the handle can be rotated after the convex plate passes through the notch, so that the convex plate and the notch intersect and abut against the inner side wall of the base, thereby preventing the handle from falling out during installation, making the installation operation of this lock more convenient.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] like Figures 1 to 7 As shown, a cabinet lock includes a panel 1 and a rotating shaft 2 rotatably disposed on the panel 1. A handle 3 is connected to the rotating shaft 2, and the rotating shaft 2 is rotated by the handle 3. The rotating shaft 2 is rotatably disposed in the base 11 of the panel 1. A sealing ring 23 is sleeved on the outer periphery of the rotating shaft 2 and abuts against the base 11 to seal the gap between the rotating shaft 2 and the base 11.

[0017] The rotating shaft 2 has a threaded hole 21, and a fixing bolt 14 is connected to the threaded hole 21 to fix the rotating shaft 2. The fixing bolt 14 is threaded to the threaded hole 21. A locking tongue is installed between the rotating shaft 2 and the fixing bolt 14 to fix the locking tongue to the rotating shaft 2 by the fixing bolt 14.

[0018] Furthermore, the rotating shaft 2 is provided with a protruding plate 22, and the base 11 is provided with a notch 111 through which the protruding plate 22 passes and is staggered with the protruding plate 22. The protruding plate 22 is adapted to the contour of the notch 111, and the protruding plate 22 can rotate with the rotating shaft 2 and correspond to the front and back of the notch 111. Thus, when installing the handle 3, the handle 3 can be rotated after the protruding plate 22 passes through the notch 111, so that the protruding plate 22 and the notch 111 are staggered and abut against and limited to the inner side wall of the base 11, thereby preventing the handle 3 from falling outward during installation.

[0019] This can also be understood as follows: when it is necessary to install the fixing bolt 14 and the lock tongue on the rotating shaft 2, it is not necessary to press the handle 3 against the front of the lock, that is, the convex plate 22 presses against the inner wall of the base 11, so that the handle 3 will not fall outward, thus making the installation and operation of this lock more convenient.

[0020] Furthermore, a lock cylinder 31 is installed on the handle 3, and the lock cylinder 31 and the lock tongue are correspondingly distributed vertically. A ring sleeve 32 and a fixing seat 33 detachably mounted on the ring sleeve 32 are provided on the inner side of the handle 3. (See reference...) Figure 4 As shown, the fixing seat 33 is installed on the ring sleeve 32 by bolts.

[0021] The mounting base 33 is threaded with a mounting bolt 41 that passes through the inner circumference of the ring sleeve 32. The mounting bolt 41 is fitted with a cover plate 4 that covers the outside of the lock cylinder 31 and a spring 43 that abuts against the inside of the handle 3. The cover plate 4 is rotatably mounted on the mounting bolt 41 and covers the lock hole 311 of the lock cylinder 31.

[0022] Specifically, the cover plate 4 is located on the outside of the handle 3 and is positioned opposite to the fixing seat 33. The other end of the spring 43 abuts against the abutment plate 321 of the ring sleeve 32. When the mounting bolt 41 is threaded onto the fixing seat 33, the mounting bolt 41 drives the cover plate to move inward and cover the outside of the lock cylinder 31, thereby making the closing of the cover plate 4 more reliable. When the mounting bolt 41 is turned outward, the spring 43 can abut against the cover plate 4 outward, so as to make it easier to rotate the cover plate 4, making it easier to rotate the cover plate 4 to avoid the lock cylinder 31. This makes it easier to open the lock cylinder 31 with a key, thus making the opening operation of the lock more convenient.

[0023] Furthermore, a retaining spring 42 is provided between the fixed seat 33 and the abutment plate 321, which is engaged with the mounting bolt 41. The retaining spring 42 is engaged on the outer periphery of the mounting bolt 41 and is located on the inner periphery of the ring sleeve 32. The retaining spring 42 limits the outward movement of the cover plate 4. That is, when the mounting bolt 4 is unscrewed from the fixed seat 33, the retaining spring 42 can abut against the abutment plate 321 to prevent the mounting bolt 41 and the cover plate 4 from coming out of the handle 3, thereby making the use of this lock more reliable.

[0024] The panel 1 has a groove 12 for accommodating the handle 3. The handle 3 is rotatably accommodated in the groove 12. The panel 1 is provided with a latch 13 that passes through the handle 3. A padlock can be provided on the latch 13 so that the handle 3 can be resisted by the padlock to abut against the outward rotation of the handle 3, thereby realizing multiple locking of the lock and improving the locking effect of the lock.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
