Description

Technical Field

[0001] The utility model relates to the field of lock structures, in particular to an anti-pinching lock. Background Art

[0002] Nowadays, smart locks are becoming more and more automated and more and more popular. Based on ergonomic design, door handles are usually integrated with smart locks. When users grasp the door handle, they can directly push and pull the door to open it after unlocking it with fingerprints or passwords, thereby improving the user experience.

[0003] Since the smart lock is close to the door gap, when the user grasps the door handle from the side close to the door gap, the back of the hand is too close to the door frame, which may cause the back of the hand to be scratched by the door frame when the door is pushed or pulled; if the user grasps the door handle from the side away from the door gap, the fingers are close to the door gap, which may cause the fingers to be pinched by the door when closing the door. Therefore, some smart locks are equipped with anti-pinch plates, which are used to seal the extension openings of the smart lock panel and the door handle facing the door gap, so that when the user unlocks the door, he can only grasp from the side away from the door gap, and the fingers cannot be extended from the other side to prevent pinching.

[0004] However, the direction of the anti-pinch finger piece of the existing lock is fixed. When it needs to be installed on doors with different rotation directions, changing the direction of the anti-pinch finger piece is time-consuming and laborious. Utility Model Content

[0024] In the prior art, a smart lock usually includes a handle, a lock body, and an anti-pinch plate. The handle is provided on the lock body, and an insertion channel for fingers to grasp is formed between the handle and the lock body. The anti-pinch plate covers one end of the insertion channel, so that the hand cannot be inserted or extended from there.

[0025] The inventor studied the above types of smart locks and found that since the anti-pinch plate is mostly fixedly installed and the direction of the anti-pinch plate is fixed, when it needs to be installed on doors with different rotation directions, the direction of the anti-pinch plate needs to be changed, and the current smart locks are time-consuming and laborious to change. Therefore, the utility model provides an anti-pinch lock, which improves the anti-pinch member 3, thereby reducing the difficulty of changing the direction of the anti-pinch plate and improving the user experience.

[0028] Example

[0029] See also Figures 1 to 5 The embodiment of the present application provides an anti-pinch lock, which includes a lock base 1, a lock handle 2 and an anti-pinch member 3. The lock handle 2 is arranged on the lock base 1, and an insertion channel for inserting fingers to grasp is formed between the lock handle 2 and the lock base 1. The anti-pinch member 3 is arranged on the lock base 1 and covers the insertion channel.

[0030] Please refer to Figure 1 to Figure 2 , the anti-pinch member 3 includes a rotating base 301, a rotating shaft 302 and a baffle 303. The rotating shaft 302 is arranged on the rotating base 301; further, the rotating shaft 302 is arranged vertically at the center of the rotating base 301. The baffle 303 is arranged on one side of the rotating base 301, and the baffle 303 cooperates with the passage opening extending into the passage; in some embodiments, one side of the baffle 303 is connected to the rotating base 301, and the other side faces the opposite direction of the rotating shaft 302. The lock base 1 is provided with an axis hole 101, and the rotating shaft 302 is inserted into the axis hole 101, so that the anti-pinch member 3 is arranged on the lock base 1 and can move axially along the direction of the rotating shaft 302, and the baffle 303 covers one side opening extending into the passage. In some embodiments, the lock handle 2 is detachably arranged on the lock base 1.

[0031] Furthermore, a base groove 102 is provided on the side of the lock base 1 close to the passage, and an axis hole 101 is provided in the base groove, and the base groove 102 matches with the rotating base 301. When the rotating shaft 302 is inserted into the axis hole 101 to the bottom, the rotating base 301 is clamped into the base groove 102, thereby fixing the rotating base 301. At this time, the baffle 303 covers the opening on one side of the passage. When the direction in which the baffle 303 is covered needs to be changed, the rotating base 301 is pulled out of the base groove 102, the anti-pinch member 3 is rotated 180°, and then the rotating base 301 is inserted back into the base groove 102, so that the baffle 303 covers the opening on the other side of the passage.

[0032] Please refer to Figure 3 to Figure 4In some embodiments, the anti-pinch lock of the present application further includes a first limit assembly 4; the first limit assembly 4 includes a blocking member 401 and an elastic return member 402. The end of the rotating shaft 302 away from the rotating base 301 passes through the shaft hole 101 and is exposed on the other side of the lock base 1; the blocking member 401 is arranged on the end of the rotating shaft 302 away from the rotating base 301, and the elastic return member 402 is sleeved on the rotating shaft 302 and arranged between the blocking member 401 and the lock base 1. When the anti-pinch member 3 changes direction of rotation, the elastic return member 402 pushes the blocking member 401 and pushes the blocking member 401 in a direction away from the lock base 1; the blocking member 401 drives the rotating shaft 302, and then pulls the rotating base 301 back into the base groove 102. In some embodiments, the elastic return member 402 is a spring. Furthermore, the blocking member 401 is a spring clip, and a spring clip groove 302a is provided on the end of the rotating shaft 302 away from the rotating base 301, and the spring clip is clamped in the spring clip groove 302a. The elastic reset member 402 provides a reset thrust, which can more stably make the rotating base 301 close to the lock base 1, and can conveniently change the direction of the baffle 303.

[0033] Please refer to Figure 5 In some embodiments, the anti-pinch lock of the present application further includes a second limit assembly 5, which is slidably mounted on the rotating shaft 302, and the second limit assembly 5 rotates synchronously with the rotating shaft 302 and can slide on the rotating shaft 302. The elastic reset member 402 is disposed between the blocking member 401 and the second limit assembly 5, with one end abutting against the blocking member 401 and the other end abutting against the second limit assembly 5, pushing the second limit assembly 5 to abut against the lock base 1.

[0034] A side of the lock base 1 away from the lock handle 2 is provided with a plurality of first position-limiting members 101a around the shaft hole 101, preferably two first position-limiting members 101a, and more preferably the two first position-limiting members 101a are symmetrically arranged around the shaft hole 101. The second position-limiting assembly 5 is provided with one or two first position-limiting matching members 5a, the first position-limiting matching member 5a surrounds the second position-limiting assembly 5 and is arranged on a side where the second position-limiting assembly 5 contacts the lock base 1, and the first position-limiting matching member 5a matches the first position-limiting member 101a; when two first position-limiting matching members 5a are provided, the two first position-limiting matching members 5a are symmetrically arranged around the axis of the second position-limiting assembly 5. When the first position-limiting fitting 5a is engaged with one of the first position-limiting fittings 101a, the baffle 303 covers the opening on one side of the passage; after the anti-pinch member 3 is rotated 180°, the first position-limiting fitting 5a is simultaneously rotated 180° to engage with the other first position-limiting fitting 101a, and the baffle 303 covers the opening on one side of the passage. In some embodiments, the first position-limiting fitting 101a is a position-limiting groove, and the first position-limiting fitting 5a is a position-limiting boss; in other embodiments, the first position-limiting fitting 101a is a position-limiting boss, and the first position-limiting fitting 5a is a position-limiting groove.

[0035] Furthermore, the first limit member 101a is a limit groove, and the first limit fitting member 5a is a limit boss; slopes are provided on both sides of the first limit member 101a, and the height of the first limit fitting member 5a is greater than or equal to the height of the base groove 102; in some embodiments, the first limit fitting member 5a is a wedge-shaped boss. When the anti-pinch hand piece 3 is rotated, the second limit assembly 5 rotates with the anti-pinch hand piece 3, and the first limit fitting member 5a slides out of the first limit member 101a along the slope, and at the same time drives the rotating shaft 302 to move axially while rotating, so that the rotating base 301 is separated from the base groove 102; after rotating 180 degrees, under the action of the elastic reset member 402, the first limit fitting member 5a slides into the first limit member 101a again, and the baffle 303 of the anti-pinch hand piece 3 rotates to the other side of the extending channel, completing the reversal. With the assistance of the first limiting fitting 5 a , when the user rotates the anti-pinch member 3 , there is no need to pull it out of the base groove 102 first, thereby optimizing the user experience.

[0036] Furthermore, the shaft hole 101 is arranged in the center of the base groove 102, and the distance from the distal end 303a of the baffle 303 to the axis of the shaft hole 101 is less than half the width of the insertion channel, so that when the anti-pinch hand piece 3 rotates, the baffle 303 will not be stuck in the insertion channel, and there is no need to pull out the anti-pinch hand piece 3 and then rotate it.

[0037] Further, the second limiting component 5 is provided with a second limiting member 5b; the rotating shaft 302 is provided with a second limiting fitting member 302b that matches with the second limiting member 5b, and the second limiting fitting member 302b is arranged along the long axis of the rotating shaft 302, preferably, arranged parallel to the axis of the rotating shaft 302. When the second limiting component 5 is sleeved on the rotating shaft 302, the second limiting member 5b can be slidably engaged with the second limiting fitting member 302b. Through the second limiting member 5b, the rotating shaft 302 and the second limiting component 5 can rotate synchronously. At the same time, since the second limiting member 5b can slide along the second limiting fitting member 302b, the second limiting component 5 can move axially along the rotating shaft 302. In some embodiments, the second limiting member 5b is a convex rib, and the second limiting fitting member 302b is a convex rib groove, and the convex rib can be slidably engaged in the convex rib groove along the convex rib groove.

[0038] The anti-pinch lock of the embodiment of the utility model further includes a lock panel, which is used to control the door lock switch and is electrically connected to the door lock switch; in some embodiments, the lock panel includes a password lock panel, and in other embodiments, the lock panel includes a fingerprint lock panel. Furthermore, the lock panel can be arranged on the inner side or outer side of the lock handle 2, or on the rotating base 301 or the lock base 1.

[0039] Compared with the prior art, the anti-pinch lock of the present invention improves the structure of the anti-pinch piece 3, and can ensure that the anti-pinch piece 3 has a simple structure and a firm connection, while making the direction change convenient and fast. When installing the anti-pinch lock, the anti-pinch piece 3 can be directly changed by simply pushing it, without the need to disassemble the anti-pinch piece 3, which greatly improves the installation speed.

[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
