Technical Field

The invention relates to the field of locks, in particular to a cat eye-preventing door lock capable of being quickly reversed.

Background

Along with the development of door industry and people's safety consciousness improve day by day, the door that has the cat eye structure receives more and more consumers ' favor, and the visitor can be convenient for observe the visitor through the cat eye on the door to the user, guarantees the security of registering one's residence. However, at present, lawless persons use cat eyes to unlock the lock and engage in illegal activities such as theft; the special unlocking tool, such as a strip-shaped pressing rod, is mainly used for extending into a room through the cat eye and opening the door handle at the indoor side, so that huge hidden dangers are brought to the personal safety and property safety of a user.

In order to cope with such a situation, door locks for preventing the door from being opened by the peep hole have been developed in the industry. At present, the door lock with the function of preventing the peephole from being unlocked in the market is basically completed through the same design thought although the styles are different: the door handle is provided with a key, a clutch part and a rotating part are arranged in the door handle, and the door handle can be locked or unlocked when the rotating part rotates. Under the locked state, the clutch part and the rotating part are mutually separated; when the user unblanks, through pressing the button, the clutch piece receives the button top and the block to changeing in the piece, the clutch piece realizes the linkage with changeing the piece, can accomplish through rotating the handle this moment and unblank.

As for the understanding of the existing cat eye prevention technology, refer to the chinese patents [ CN205153697U a cat eye prevention structure ], [ CN206600060U cat eye prevention unlocking structure and cat eye prevention fingerprint lock ].

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

The invention discloses a door lock with rapid reversing function for preventing peep hole from unlocking, and referring to fig. 1-4, the door lock comprises: a handle 11, a key 14, a key compression spring 12, a clutch piece 10, a handle connecting piece 5 and a reversing stud 1.

The key compression spring 12 is sleeved at one end of the key 14, and the key 14 is pressed against the handle 11 through the key compression spring 12, so that the key 14 is rebounded after being pressed; the key 14 and the handle 11 are fixed in the circumferential direction, so that the key 14 rotates along with the rotation of the handle 11 all the time; the button 14 is also fixedly connected with the clutch 10, specifically fixed by a screw, so that the handle 11, the button 14 and the clutch 10 are all in linkage rotation. In addition, referring to fig. 5, the clutch member 10 and the rotating member 3 are in detachable engagement connection, and the clutch member 10 is switched between the state of disengaging the rotating member 3 and engaging the rotating member 3; specifically, when the key 14 is pressed in, the clutch member 10 and the rotating member 3 are engaged and rotate in a linkage manner, and when the key 14 rebounds outwards, the clutch member 10 and the rotating member 3 are disengaged, so that transmission does not occur.

It should be noted that there is a certain transmission relationship between the rotating member 3 and the lock tongue, and when the rotating member 3 rotates in different directions, the lock tongue correspondingly makes a telescopic motion to achieve unlocking or locking, and since the transmission of this part is the prior art in the industry and is not in the improvement range of the present invention, it is not described in detail, and a person skilled in the art only needs to know how the rotating member 3 in the embodiment rotates.

The handle link 5 is fixedly mounted on the handle 11, so that the handle link 5 and the handle 11 are always kept in an interlocked state. Referring to fig. 6, the handle link 5 includes a circular portion 51, and a semicircular ring portion 52 and a protruding limit portion 53 integrally formed on the circular portion 51, the protruding limit portion 53 and the semicircular ring portion 52 are oppositely disposed, so that the handle link 5 forms two sections of idle strokes, that is, two end arc grooves formed between the protruding limit portion 53 and the semicircular ring portion 52. The reversing stud 1 is fixedly connected to the rotating piece 3, the reversing stud 1 is abutted to the semicircular ring part 52 of the handle connecting piece 5, and the reversing stud 1 is positioned on the handle 11 of the handle connecting piece 5 in the lifting and rotating direction.

The working process and working principle of the present invention are explained in detail below:

referring to fig. 7 and 9, when a user unlocks the lock, the button 14 is pressed while the handle 11 is rotated, and at this time, the button 14 pushes the clutch member 10 to move, so that the clutch member 10 is clamped into the rotating member 3, and the handle 11, the button 14, the clutch member 10 and the rotating member 3 are in a linkage rotating state, so that the rotating member 3 can be rotated by pressing the handle 11 downwards, and the unlocking is realized. Therefore, the unlocking process is driven by the clutch piece 10, if a lawbreaker extends a tool into a room through a cat eye and directly presses the handle 11, the clutch piece 10 and the rotating piece 3 cannot be linked at the moment, only the handle 11, the key 14 and the handle connecting piece 5 can rotate, referring to fig. 7-8, the protruding limit part 53 of the handle connecting piece 5 can move for an idle stroke until the protruding limit part is tightly pressed on the reversing stud bolt 1 and cannot rotate any more, and therefore the handle 11 can only idle.

Referring to fig. 9 and 7, when the user resets and locks, the finger releases the button 14 and lifts the handle 11 directly. At this time, the clutch member 10 is disengaged from the rotating member 3, and no linkage is generated between the two. Because in the process of unlocking at the beginning, the handle connecting piece 5 and the rotating piece 3 rotate synchronously, so the relative position of the reversing stud 1 and the semicircular ring part 52 can not be changed, and the reversing stud 1 always keeps abutting against the semicircular ring part 52 and is positioned on the handle 11 of the semicircular ring part 52 in the lifting and rotating direction. In the process of lifting the handle 11, the handle connecting piece 5 rotates along with the handle 11, and the reversing stud bolt 1 is jacked through the semicircular ring part 52, so that the rotating piece 3 rotates; therefore, the rotating piece 3 can be rotated by lifting the handle 11 alone, and resetting and locking are completed. Specifically, referring to fig. 7 and 9, taking the example of pressing down the handle 11 clockwise by the right hand (facing the handle 11 as a reference), the handle connecting piece 5, the clutch piece 10 and the rotating piece 3 synchronously rotate clockwise to complete unlocking; the handle 11 is lifted anticlockwise, the key 14 is loosened simultaneously, the handle 11 and the handle connecting piece 5 rotate anticlockwise synchronously, the handle connecting piece 5 pushes the rotating piece 3 to rotate anticlockwise, and resetting and locking are achieved.

Therefore, when the lock is unlocked, the clutch piece 10 is used for transmitting the rotating piece 3, so that the cat eye prevention unlocking is realized; when the lock is locked, the rotating piece 3 is driven to rotate only by the handle connecting piece 5 on the handle 11 without being driven by the clutch piece 10, so that a user can release the key 14 and directly lift the handle 11 to realize quick reset and locking.

In addition, when the handle 11 is quickly reversed, the reversing stud 1 is only required to be screwed off, the handle 11 is directly rotated by 180 degrees, then the reversing stud 1 is screwed again to complete reversing, only the pressing-down and lifting-up directions of the handle 11 are changed, and other functions are completely consistent. The working process after the direction change is as follows: referring to fig. 10-11, when the handle 11 is pressed counterclockwise (facing the handle 11 as a reference), the handle connecting member 5, the clutch member 10 and the rotating member 3 rotate counterclockwise synchronously to complete unlocking; the handle 11 is lifted clockwise, the handle 11 and the handle connecting piece 5 synchronously rotate clockwise, the handle connecting piece 5 pushes the rotating piece 3 to rotate clockwise, and resetting and locking are completed.

In a preferred embodiment, one end of clutch member 10 is provided with a boss structure 101, the corresponding end of rotating member 3 is provided with a groove structure 31 engaged with boss structure 101, and groove structure 31 and boss structure 101 are adapted to be engaged with or disengaged from each other. The clutch member 10 and the rotating member 3 are engaged or disengaged by such an axial insertion manner, but it is within the scope of the present invention to employ other connecting manners, as long as the detachable connection is achieved.
