Description
Technical Field
[0001] The present application relates to the technical field of locks, and in particular to a cabinet panel lock. Background Art
[0002] At present, panel locks are widely used in various industries, such as generator sets and trucks. Panel locks usually have a handle that can be folded and installed in the groove of the lock seat. The handle can be pulled up from the groove to rotate the lock tongue to unlock or lock. A lock body fixed by a lock body nut is also installed in the lock seat. The lock body has a lock core. The front end of the lock core is fixed with a lock plate by screws. The lock plate controlled by the lock core can lock the lock tongue and limit the handle from being in a free state.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.
[0034] In this embodiment, for the convenience of description, the side of the lock base 1 with the groove is called the outer side, and the side of the lock base 1 away from the groove is called the inner side.
[0035] The present application embodiment discloses a cabinet panel lock. Figure 1 ,2 The panel lock includes a lock seat 1, a lock body 2, a handle 3, a rotating shaft 4, a locking tongue 5 and an adjusting seat 6. The rotating shaft 4 passes through the lock seat 1, and the handle 3 is rotatably connected to the end of the rotating shaft 4 located outside the lock seat 1 through a pin, and the adjusting seat 6 is fixedly connected to the end of the rotating shaft 4 located inside the lock seat 1. The locking tongue 5 is connected to the adjusting seat 6. When the handle 3 is pulled out of the groove of the lock seat 1 and rotated, the rotating shaft 4 will rotate with the adjusting seat 6 and the locking tongue 5, thereby controlling the unlocking and locking of the panel lock.
[0036] Reference Figure 2 , 3 The end of the rotating shaft 4 passing through the outer side of the lock seat 1 is also sleeved with a gasket 7 and an elastic pad 8, and the elastic pad 8 can be made of a material with elastic deformation ability such as rubber. The arrangement of the gasket 7 and the elastic pad 8 can provide the handle 3 with a movable space when pulling in and out of the lock seat 1, and block the gap between the lock seat 1 and the rotating shaft 4, achieving a waterproof effect.
[0037] Reference Figure 3 , 4 The adjusting seat 6 is a cylindrical structure with one end closed, and a boss 41 is provided at the end of the rotating shaft 4 away from the handle 3. The boss 41 is in a square structure, and a screw 42 coaxial with the rotating shaft 4 is fixed on the boss 41. The adjusting seat 6 is provided with a mounting hole 61 adapted to the boss 41. During installation, the boss 41 is inserted into the mounting hole 61, and the screw 42 passes through the mounting hole 61 and is locked by the nut 14 to achieve a fixed connection between the adjusting seat 6 and the rotating shaft 4.
[0038] Reference Figure 1 , 2 An adjustment component is provided between the adjustment seat 6 and the lock tongue 5, and is used to adjust the distance between the lock tongue 5 and the lock seat 1. Specifically, the adjustment component includes an external thread and a locking member distributed on the outer periphery of the adjustment seat 6. The external thread of the adjustment seat 6 extends along the axis direction of the rotating shaft 4, and the lock tongue 5 is provided with a first threaded hole 51 threadedly connected to the external thread. The lock tongue 5 and the adjustment seat 6 are threadedly connected. When encountering cabinet doors of different thicknesses, it is only necessary to rotate the lock tongue 5.
[0039] Reference Figure 1 , 2The locking member is used to lock the adjusted position of the lock tongue 5. The locking member includes a locking bolt 13, and an outer wall of the adjustment seat 6 is provided with an adjustment groove 62 for inserting the locking bolt 13. The adjustment groove 62 extends in a direction parallel to the axis of the rotating shaft 4, and a second threaded hole 52 for threading the locking bolt 13 is provided on the lock tongue 5. After adjusting the position of the lock tongue 5, the locking bolt 13 is inserted into the adjustment groove 62 through the second threaded hole 52, and tightened to lock the lock tongue 5. It should be noted here that the number of the adjustment groove 62 and the second threaded hole 52 can be selected according to actual conditions, and can be one, two or more. This embodiment is described by taking two as an example.
[0040] Reference Figure 3 , 4 In order to allow the lock tongue 5 to unlock and lock more accurately, a limiting groove 63 is provided at the bottom of the adjustment seat 6, and the limiting groove 63 extends circumferentially around the rotating shaft 4. A limiting column 10 inserted into the limiting groove 63 is fixed on the inner side of the lock seat 1. When the lock seat 1 rotates until the limiting column 10 abuts against one end of the limiting groove 63, the lock tongue 5 is in an unlocked state; and when the lock seat 1 rotates until the limiting column 10 abuts against the other end of the limiting groove 63, the lock tongue 5 is in a locked state. This structural design can ensure that the lock tongue 5 is accurately switched between the locked and unlocked states.
[0041] In order to facilitate the installation of the adjustment seat 6, two limiting grooves 63 are symmetrically arranged around the rotation axis 4. Of course, in other embodiments, the number of the limiting grooves 63 can also be more.
[0042] Reference Figure 1 , 2 The lock body 2 includes a lock plate 9 and a lock core. The lock body 2 passes through the lock seat 1 and is locked on the lock seat 1 through a lock body nut 11 and a lock cap 12. The lock core is located in the lock body 2. The lock plate 9 includes a connecting portion 91 and a locking portion 92. The connecting portion 91 is a disc-shaped structure. The connecting portion 91 is fixedly connected to the lock core by screws and is controlled by the lock core. The locking portion 92 is an arc-shaped structure. The axis of the locking portion 92 coincides with the axis of the connecting portion 91. The locking portion 92 extends in a length direction parallel to the rotating shaft 4, and its length covers the adjustment range of the lock tongue 5.
[0043] Further, see Figure 5 A lock slot 54 is provided at one end of the lock tongue 5, and an oblique opening 55 is provided at the notch of the lock slot 54 for the lock piece 9 to rotate into or out of the lock slot 54. This design enables the lock piece 9 to smoothly enter or exit the lock slot 54, thereby effectively locking or unlocking the panel lock.
[0044] In addition, at least one group of connecting holes 53 is formed on the lock tongue 5. Each group of connecting holes 53 has two connecting holes, which are symmetrically distributed around the axis of the rotating shaft 4. When the cabinet door is long, these connecting holes 53 can be used to connect the connecting rods at the upper and lower ends of the cabinet door. When the lock tongue 5 is rotated and locked, the connecting rods drive the latches at the upper and lower ends of the cabinet door to be inserted into the door frame, so as to enhance the stability of the cabinet door locking.
[0045] The locking end of the lock tongue 5 gradually narrows in the direction away from the adjustment seat 6, which helps to better help the lock tongue 5 transition to a locked state during the locking process. At the same time, a buffer groove 56 is also provided at the locking end of the lock tongue 5, which is used to save material costs and prevent the material from being too thick, resulting in deformation during the die-casting process.
[0046] The implementation principle of a cabinet panel lock in the embodiment of the present application is:
[0047] When facing cabinet doors of different thicknesses, the lock tongue 5 is rotated to a desired position and then locked by the locking bolt 13, so that the panel lock can adapt to cabinet doors of different thicknesses.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
