Description

Technical Field

[0001] This utility model relates to the field of handle lock technology, and in particular to a bearing clutch structure suitable for handle locks or ball locks. Background Technology

[0002] Existing handle locks typically use a metal sheet and nut or a metal sheet and spring clip for fixation. This type of structure is complex to assemble, and after assembly, the handle may lose its elasticity when pressed down and fail to return to its original position. Over time, the handle may also loosen and sag, leading to unlocking failures.

[0003] To address the aforementioned issues, this application proposes a bearing-driven clutch structure suitable for handle locks or ball locks. Utility Model Content

[0004] This utility model provides a bearing-driven clutch structure suitable for handle locks or ball locks to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention provides a bearing clutch structure suitable for handle locks or ball locks, including a handle and a base. The handle is installed on the front side of the handle, and a bearing pressure plate is fixedly connected inside the base. A bearing is embedded in the inner side of the bearing pressure plate, and a clutch is connected through the rear side of the bearing pressure plate. The bearing is sleeved on the front part of the outer end of the clutch, and a torsion spring is connected between the bearing pressure plate and the clutch.

[0006] Preferably, a plurality of self-tapping screws are connected through the rear side of the bearing plate, and the bearing plate is fixedly connected to the inside of the base by the self-tapping screws, and the number of the self-tapping screws is set to four.

[0007] Preferably, two screws are connected through the rear side of the clutch, and the clutch is fixedly connected to the rear side of the handle by the screws.

[0008] Preferably, a bottom cover is snapped onto the rear side of the base, and two connecting pipes are connected through the front side of the bearing pressure plate, with the connecting pipes penetrating the bottom cover.

[0009] Compared with related technologies, the bearing-driven clutch structure for handle locks or ball locks provided by this utility model has the following advantages:

[0010] By cooperating with bearing plates, bearings, torsion springs, and clutches, and then fixing each structure with self-tapping screws and bolts, the clearance between each component is controllable. Direct screw fixing increases structural stability, improves assembly efficiency, prevents jamming and loss of elasticity, and prevents handle loosening and sagging even after long-term use, effectively increasing service life.

[0020] Please see Figure 1-8 The technical solution provided by this utility model specifically includes the following embodiments:

[0021] A bearing clutch structure suitable for handle locks or ball locks includes a handle 1 and a base 2. The handle 1 is installed on the front side of the handle 1. A bearing pressure plate 5 is fixedly connected inside the base 2. A bearing 3 is embedded in the inner side of the bearing pressure plate 5. A clutch 8 is connected through the rear side of the bearing pressure plate 5. The bearing 3 is sleeved on the front part of the outer end of the clutch 8. A torsion spring 7 is connected between the bearing pressure plate 5 and the clutch 8.

[0022] Multiple self-tapping screws 6 are connected through the rear side of the bearing plate 5. The bearing plate 5 is fixedly connected to the inside of the base 2 by the self-tapping screws 6. The number of self-tapping screws 6 is set to four. The self-tapping screws 6 can be used to fix the bearing plate 5 inside the base 2. The four self-tapping screws 6 are distributed in pairs, with the two on the left side distributed vertically and the two on the right side distributed vertically. The bearing plate 5 has holes for the self-tapping screws 6 to pass through.

[0023] Two screws 9 are connected through the rear side of the clutch 8. The clutch 8 is fixedly connected to the rear side of the handle 1 by the screws 9. The screws 9 can fix the clutch 8 and the handle 1 together so that the two can rotate synchronously.

[0024] The base 2 is fitted with a bottom cover 10 at the rear. The bearing plate 5 is connected to two connecting pipes 4 at the front. The connecting pipes 4 pass through the bottom cover 10. The bottom cover 10 can seal the rear of the base 2. At the same time, the bottom cover 10 is provided with multiple adapter holes, so it does not affect the extension and installation of each structure.

[0025] A screw seat 51 is integrally formed on both the left and right sides of the rear side of the bearing pressure plate 5. The hole on the bearing pressure plate 5 also passes through the screw seat 51. At the same time, the bearing pressure plate 5 also has a hole for the connecting tube 4 to pass through at the location of the screw seat 51. There is a hexagonal block at the front end of the connecting tube 4. The front side of the bearing pressure plate 5 at the location of the connecting tube 4 passing through the hole also has an internal hexagonal groove. Thus, when the connecting tube 4 passes through the hole, the hexagonal block is embedded in the internal hexagonal groove to achieve a limit and prevent it from rotating at will. At the same time, a stop block 52 is integrally formed on the upper and lower sides of the rear side of the bearing pressure plate 5.

[0026] The base 2 has an integrally formed positioning rib and screw holes for matching the shape of the bearing plate 5. The self-tapping screw 6 is screwed into the screw hole to fix the bearing plate 5.

[0027] The clutch 8 has a stop block 2 81 integrally formed on both the upper and lower sides of its front side. The two ends of the torsion spring 7 are in the relaxed state. Figure 7 and Figure 8 The positional relationship shown is that the two ends of the torsion spring 7 are located on the opposite sides of the adjacent screw seat 51 and the stop block 52, while one end of the torsion spring 7 is also located on the side of one of the stop blocks 81. The two stop blocks 81 are located on the opposite sides of the two stop blocks 52, respectively, and do not interfere with each other. When the handle 1 is turned, the clutch 8 rotates accordingly, which will twist the torsion spring 7 through the stop block 81 to generate a spring force. This spring force can be used to drive the clutch 8 and the handle 1 to rotate back to the original position.

[0028] Working principle:

[0029] When the handle 1 is turned, the clutch 8 rotates accordingly. During this time, one end of the torsion spring 7 is pushed by a 81 on the clutch 8, which generates a spring force. When the handle 1 is stopped, the spring force of the torsion spring 7 will push the clutch 8 back to its original position, so that the handle 1 is also lifted again. When the clutch 8 is rotating, the clutch 8 and the bearing pressure plate 5 are movably connected through the bearing 3, so that the handle 1 can rotate smoothly when it is turned and lifted.
