Description

A universal clutch for a lock

technical field

The utility model relates to a lock, in particular to a universal clutch of the lock.

Background technique

Smart door locks are generally equipped with a clutch. The function of the clutch is that when the clutch is in the disconnected state, when the handle is turned, the deadbolt will not withdraw from the buckle, so that it can effectively prevent others from inserting tools from the peephole. Unscrew the door lock.

The structure of the conventional clutch is complicated and its versatility is not strong, so it is necessary to improve it.

Contents of the invention

Aiming at the deficiencies in the prior art, the utility model provides a universal clutch for locks, which is suitable for various locks and has a simple structure.

The utility model is realized through the following technical solutions: a universal clutch for a lock, comprising a clutch shell connected to the door handle and a clutch core connected to the deadbolt structure, the clutch core is nested in the clutch shell, the The clutch housing is provided with a first through hole, the clutch core is provided with a second through hole communicating with the first through hole, and also includes a pin and one end of the pin toward the first through hole. The hole and the second through hole are withdrawn from the first mechanism, the other end of the pin is in contact with an arc-shaped plate, the axis of the arc-shaped plate is coaxial with the rotation axis of the door handle, and it also includes driving the The second mechanism of the arc plate moving up and down. Under normal circumstances, under the action of the first mechanism, the bolt exits the first through hole and the second through hole, and the clutch shell and the clutch core cannot realize linkage. At this time, turning the door handle will not open the door, so as to avoid people from the peephole. Putting in the tool to open the door occurs. When the door needs to be opened, the arc-shaped plate rises through the mechanism. During the rising process, the latch passes through the first through hole and the second through hole. When the handle is turned, the hook can drive the bolt to move. During the turning process, the curved plate can ensure that the latch is always in the same position.

In the above technical solution, specifically, the first mechanism includes a third through hole provided on the clutch housing, the pin is set in the third through hole, and the pin is set inside the third through hole A step is provided at the position of the spring, and the two ends of the spring are respectively located in contact with the step and the clutch case, and the spring is in a compressed state.

In the above technical solution, preferably, the outer ring of the clutch housing is provided with a ring of protrusions, and two upright posts are provided on both sides of the protrusion on the back of the panel of the lock, and the door handle faces clockwise and counterclockwise. When rotating, the protrusions are respectively in contact with the uprights on both sides. This design is to limit the angle of rotation of the handle.

In the above technical solution, preferably, the second mechanism includes a slider, the slider is connected to the bottom of the arc-shaped plate, the slider is slidably arranged in a chute, and the slider is provided with There is a toggle button, and one end of the toggle button protrudes from the front of the panel. When in use, the slider can be slid by turning the toggle button, thereby changing the position of the curved plate.

In the above technical solution, preferably, a snap ring is further included, the snap ring has at least one narrowed bayonet, and the toggle button is connected to the slider after passing through the snap ring. When the toggle is moved upwards, the toggle passes through the bayonet, and then the buckle can block the toggle and prevent the toggle from sliding down.

The utility model has the following beneficial effects: under normal circumstances, the bolt exits the first through hole and the second through hole under the action of the first mechanism, and the clutch shell and the clutch core cannot realize linkage, and at this time, turning the door handle will not Open the door to avoid the situation where people put tools into the peephole to open the door. When the door needs to be opened, the mechanism makes the arc plate rise. During the rise, the latch passes through the first through hole and the second through hole. When the handle is turned , the hook can drive the bolt to move. During the turning process, the curved plate can ensure that the latch is always in the same position.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

Referring to Figures 1-5, a universal clutch for a lock includes a clutch case 2 connected to a door handle 1 and a clutch core 3 connected to a lock tongue structure (not shown in the figure), and the clutch core 3 is nested in the In the clutch housing 2, the clutch housing 2 is provided with a first through hole 21, and the clutch core 3 is provided with a second through hole 31 communicating with the first through hole 21, and also includes a latch 4 And the first mechanism that withdraws one end of the bolt 4 toward the first through hole 21 and the second through hole 31, the other end of the bolt 4 is in contact with an arc-shaped plate 5, and the arc-shaped plate 5 is coaxial with the rotation axis of the door handle 1, and also includes a second mechanism for driving the arc plate 5 to move up and down.

The first mechanism includes a third through hole 22 provided on the clutch housing 2 and a spring 7, the pin 4 is set in the third through hole 22, and the pin 4 is set in the third through hole 22 A step 41 is provided at the inner position, the spring 7 is sleeved on the latch 4, and the two ends of the spring 7 are respectively in contact with the step 41 and the clutch housing 2, and the spring 7 is in a compressed state. Under the action of the spring, the pin has a tendency to be pulled out toward the first through hole and the second through hole.

The outer ring of the clutch housing 2 is provided with a ring of protrusions 22, and the back of the panel 100 of the lockset is provided with two columns 101 on both sides of the protrusion 22. When the door handle 1 is turned clockwise and counterclockwise, , the protrusions 22 are respectively in contact with the uprights 101 on both sides. This design is to limit the angle of rotation of the handle.

Described second mechanism comprises a slide block 61, and described slide block 61 links to each other with the bottom of described arc-shaped plate 5, and described slide block 61 is provided with chute 62 in sliding, and described slide block 61 is provided with dial button 63, one end of the button 63 protrudes from the front of the panel 100.

It also includes a snap ring 63 , the snap ring has at least one narrowed bayonet 631 , and the toggle button is connected to the slider 61 after passing through the snap ring 63 .

Under normal circumstances, under the action of the spring, the bolt exits the first through hole and the second through hole, and the clutch shell and the clutch core cannot realize linkage. At this time, turning the door handle will not open the door, preventing people from entering the door through the peephole. When the tool opens the door, when the door needs to be opened, the slider can be slid upwards by turning the button, so that the arc plate rises. During the rising process, the pin passes through the first through hole and the second through hole. When the handle is turned , the hook can drive the bolt to move. During the turning process, the curved plate can ensure that the latch is always in the same position.

This embodiment is a preferred example of the utility model, but it does not limit the scope of protection of the utility model. In addition to the implementation disclosed in this embodiment, the utility model also has other multiple implementations, such as withdrawing the latch and There are many kinds of first mechanisms for inserting into the first through hole and the second through hole, for example, a magnet adsorption method may be used. There are also many second mechanisms for pushing the arc plate up and down, for example, the electromagnet absorbs the down spring to return to the up, and these are the replacements that people in the field can easily think of.
