Description

Technical Field

[0001] The utility model relates to a lock body, in particular to a lock core lever clutch structure. Background Art

[0002] The lock body is one of the components of the lock. There are many types of lock bodies, the most common ones are one-way lock bodies, three-way lock bodies, four-way lock bodies, etc. It is generally used on anti-theft doors and is responsible for the basic anti-theft work of anti-theft doors. The lock core controls the operation of the lock body, and the lock body is responsible for opening and locking doors and windows, playing an important role in anti-theft. When the handle is lifted 45 degrees to lock, the key cannot be pulled out, and when it is lifted 90 degrees to unlock and pull out. The traditional structure needs to be reversed and reset to pull out when the key is opened 90 degrees. If the lock core is misaligned, it is difficult to continue to rotate, affecting the use.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, a lock cylinder lever 1 structure comprises a lever 1, a driving plate 2 and a driven plate 3 which are coaxial and arranged in sequence, the lever 1 is inserted into the driving plate 2 for circumferential rotation, the driving plate 2 is provided with an engagement groove 4 on the end surface facing the driven plate 3, two engagement grooves 4 are symmetrically arranged along the outer edge of the driving plate 2, the driven plate 3 is provided with two engagement blocks 5 at the outer edge corresponding to the engagement grooves 4, the driven plate 3 is provided with a linkage part 1 6 on the outer wall, and the driven plate 3 is provided with a linkage part 2 7 on the end away from the driving plate 2, and the driving plate 2 and the driven plate 3 are elastically abutted. The lever 1 transmits power to the driving plate 2, the driving plate 2 rotates while maintaining contact with the driven plate 3, and the distance between the driving plate 2 and the driven plate 3 is adjusted by the cooperation between the engagement groove 4 and the engagement block 5. It should be pointed out that the engagement block 5 enters or escapes from the engagement groove 4 so that the driving disk 2 pushes the driven disk 3 to move relatively, thereby triggering the action of the linkage part 1 6 and the linkage part 2 7. The subsequent triggering components are mature technologies and will not be elaborated or limited in detail here.

[0012] The driving disk 2 is provided with a through square groove 8, and the lever 1 is inserted into the square groove 8 and is connected in a circumferential direction. The square groove 8 rotates in conjunction with the lever 1, and the lever 1 is usually in the shape of a square bar. This is a simple linkage rotation cooperation method. The driven disk 3 is provided with a reinforcement part 9 at the notch of the square groove 8 on the side facing the driving disk 2. The reinforcement part 9 is a semicircular structure to strengthen the local structural strength. The linkage part 1 6 is distributed in a step-shaped manner on the end face facing the driving disk 2, and the linkage part 1 6 is provided with two symmetrically positioned ones. Here, it is mainly explained that the linkage part 1 6 and the linkage part 2 7 are linkage cooperation methods in two different directions, which can trigger a variety of interlocking structures. The linkage part 2 7 is in a rod shape, and four linkage parts 2 7 are evenly arranged along the outer edge. Different from the interlocking form of the linkage part 1 6, the plug-in rod structure may have a large load when rotating, so four are arranged to improve the service life.

[0013] The key is disengaged in the standby state, which means it is locked. If you insert the key and rotate it 90 degrees left or right, it is closed, but the key cannot be pulled out.

[0014] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. At the same time, the basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the art of this industry should understand.
