Description

Technical Field

[0001] The utility model belongs to the technical field of door locks, and in particular relates to an intelligent lock. Background Art

[0002] It is usually more complicated to open the door from the outside with a smart lock. It requires a mechanical key or electronic identification such as an access card, password, fingerprint recognition, etc. to open the door. From the inside, the door can be opened quickly by the handle. This setting allows criminals to destroy the structure of the cat's eye on the door or use a thin and long tool to reach into the door through the gap at the bottom of the door to pull the handle to open the door, and the safety performance cannot be guaranteed.

[0003] In response to the above problems, various smart lock anti-peephole structures have appeared on the market, such as the Chinese patent CN111411822A discloses "Smart lock anti-peephole device", which can achieve the separation between the handle and the square rod rotating sleeve when the cat's eye button is not pressed by combining the cat's eye button, the cat's eye connecting shaft and the movable bolt. However, its structure is relatively complex, the number of accessories is large, and the installation cost is relatively high. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a smart lock with simple structure, good anti-cat's eye function and low assembly difficulty.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a smart lock, comprising:

[0006] Lock panel;

[0007] A handle, rotatably connected to the lock panel;

[0008] The transmission assembly comprises an inner body and an outer body which are connected with each other, and the inner body is used for inserting the square steel;

[0009] The movable part is connected to the connecting pin and is used to drive the connecting pin to move back and forth. It has a locking position and an unlocking position. When in the locking position, the connecting pin extends into the outer body and the inner body in turn to realize the linkage between the two. When in the unlocking position, the connecting pin at least separates from the inner body so that the outer body and the inner body can move independently.

[0010] The utility model utilizes the up and down movement of the movable part to make it enter the unlocking position or the locking position, driving the connecting pin to realize the non-linkage cooperation or linkage cooperation between the inner body and the outer body, thereby quickly realizing the anti-cat's eye function, which is easy to operate and has high safety performance. The structure of the movable part, the connecting pin and the transmission component is simple, which greatly reduces the number of parts and components and reduces the difficulty of assembly.

[0011] Furthermore, the movable part is provided with an elastic part, the elastic part is formed with a locking positioning area, the lock panel is provided with a locking convex column, the locking positioning area and the locking convex column are positioned and matched to limit the movable part to the locking position or the unlocking position. The locking positioning area and the locking convex column can limit the movable part to the locking position or the unlocking position, thereby preventing the movable part from switching between the two positions at will. The locking positioning area is arranged on the elastic part, which is convenient for processing and the switching operation is relatively labor-saving.

[0012] Furthermore, the elastic part is formed by partially hollowing out the movable part, and the locking positioning area is a groove arranged adjacent to the movable part. The elastic part is formed by partially hollowing out the movable part, and its elasticity is relatively large, and the positioning of the locking position and the unlocking position is more stable, and it does not require excessive effort during operation, which is convenient for operation and switching, and the groove structure is simple and easy to process.

[0013] Furthermore, a baffle extending vertically along the length direction of the lock panel is formed on the back of the lock panel, and the side wall of the movable part abuts against the baffle. The baffle abuts against the movable part to ensure that the movable part can move vertically up and down and avoid deviation during the movement.

[0014] Furthermore, one of the movable part and the back of the lock panel is provided with a travel groove, and the other is provided with a limit column that can extend into the travel groove. The travel groove and the limit column cooperate to limit the range of up and down movement of the lock panel to prevent it from excessive movement, and the above structure can assist the locking positioning area and the locking protrusion to form accurate positioning of the locking position and the unlocking position.

[0015] Furthermore, the movable part is provided with a lock key, which extends out of the through hole of the locking panel, and the outer periphery of the through hole is provided with a schematic area. The lock key is convenient for applying external force to drive the movable part to move up and down, and the schematic area is convenient for the user to intuitively judge the position of the lock key, and then determine whether it is in a safe state of anti-cat's eye.

[0016] Furthermore, the outer wall of the connecting pin forms a flange that can cooperate with the outer body to prevent it from falling off. The flange can effectively prevent the connecting pin from falling off the outer body at will, thereby ensuring the stability of the overall assembly structure.

[0017] The beneficial effects of the utility model are as follows: the anti-cat's eye function is quickly realized by simply cooperating with the movable parts, connecting pins and transmission components, the operation is convenient, the safety performance is high, the cooperating structure is simple, the number of parts is greatly reduced, and the assembly difficulty is low; the locking positioning area and the locking boss cooperate to limit the movable part to the locking position or the unlocking position, and avoid the movable part from switching between the two positions at will; the elastic part is formed by partially hollowing out the movable part, which is convenient for processing, has greater elasticity, saves effort in switching operation, and has more stable positioning of the locking position and the unlocking position; the travel groove and the limit column cooperate to limit the range of up and down movement of the lock panel, avoid its excessive movement, and can assist the locking positioning area and the locking boss to form accurate positioning of the locking position and the unlocking position.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] like Figure 1-Figure 7 As shown, a smart lock includes a lock panel 1, a handle 2 rotatably connected to the lock panel 1, a transmission assembly 3, a connecting pin 5, and a movable part 4. The transmission assembly 3 includes an inner body 31 and an outer body 32 connected inside and outside. The center of the inner body 31 is used to insert a square steel (not shown in the figure), and the inner body 31 and the outer body 32 can move relatively independently. The movable part 4 is connected to the connecting pin 5 and is used to drive the connecting pin 5 to move back and forth. The movable part 4 has a locking position and an unlocking position.

[0030] In the locked position, the connecting pin 5 sequentially extends into the outer body 32 and the inner body 31 to realize the linkage between the two. In the unlocked position, the connecting pin 5 at least detaches from the inner body 31, so that the outer body 32 and the inner body 31 can move independently. In other words, in the locked position, the anti-cat's eye structure is closed, and the handle 2 is turned. Driven by the square steel, the rotation of the inner body 31 can drive the outer body 32 to rotate synchronously through the connecting pin 5, so that the door can be opened; in the unlocked position, the anti-cat's eye structure is opened, and the connecting pin 5 will not realize the linkage between the inner body 31 and the outer body 32. At this time, when the handle 2 is turned, the square steel can only drive the inner body 31 to rotate, and the outer body 32 will not rotate synchronously, and then the door cannot be opened.

[0031] In this embodiment, the connecting pin 5 is fixedly connected to the top of the movable member 4. Figure 8 As shown, the outer body 32 has a through hole 321 for the connecting pin 5 to vertically extend therein, and an embedding groove 311 is formed on the inner body 31 at a position corresponding to the through hole 321. When the connecting pin 5 only extends into the through hole 321 but not into the embedding groove 311, the inner body 31 and the outer body 32 move independently, and when the connecting pin 5 extends into the through hole 321 and enters the embedding groove 311, the inner body 31 and the outer body 32 can rotate synchronously under the drive of the connecting pin 5.

[0032] like Fig. 9 As shown, in order to prevent the connecting pin 5 from being separated from the outer body 32 at will, a flange 51 with an increased outer diameter is formed on the outer wall of the connecting pin 5 , and the flange 51 cooperates with the outer body 32 to prevent separation.

[0033] In order to realize the function of limiting the movable part 4 in the locked position or the unlocked position and prevent the movable part 4 from switching between the locked position and the unlocked position at will, an elastic part 41 is provided on the movable part 4, and the elastic part 41 forms a locking positioning area 411, and the lock panel 1 is provided with a locking boss 11, and the locking positioning area 411 and the locking boss 11 are positioned and matched, so as to limit the movable part 4 in the locked position or the unlocked position.

[0034] More specifically, if Figure 3 , Figure 5 , Fig. 9 As shown, the elastic part 41 is formed by partially hollowing out the movable part 4, and the locking positioning area 411 is two adjacent grooves arranged on the upper and lower parts of the elastic part 41. Thus, when an external force is applied to push the movable part 4, since the position of the locking boss 11 is relatively fixed, the locking positioning area 411 switches up and down with the movable part 4 to different grooves to be positioned and matched with the locking boss 11. In the absence of an external force, under the stopping action of the locking positioning area 411 and the locking boss 11, the movable part 4 can stay firmly in the locked position or unlocked position. Since the elastic part 41 is formed by partially hollowing out the movable part 4, it has greater elasticity, and the positioning of the locked position and the unlocked position is more stable. Moreover, it does not require excessive effort during operation, which is convenient for operation switching.

[0035] In order to ensure that the movable part 4 can move vertically up and down, Figure 3 The directions shown are roughly defined as up, down, left and right. A baffle 12 extending vertically along the length direction of the lock panel 1 is formed on the back of the lock panel 1, and the side wall of the movable part 4 is against the baffle 12. Therefore, when the movable part 4 moves up and down, under the restriction of the baffle 12, its up and down movement direction can be guaranteed to be parallel to the length direction of the lock panel 1.

[0036] In order to limit the range of the lock panel 1 to move up and down, one of the movable member 4 and the back of the lock panel 1 is provided with a travel groove 42, and the other is provided with a limit column 13 that can extend into the travel groove 42. In this embodiment, the travel groove 42 is provided on the movable member 4, and the limit column 13 is fixedly provided on the back of the lock panel 1, and the number of the travel groove 42 and the limit column 13 are both two. The travel groove 42 extends in the vertical direction, that is, its extension direction is the same as that of the baffle 12.

[0037] like Figure 1As shown, the movable part 4 is provided with a lock key 43, which extends from the through hole 14 of the lock panel 1, that is, the lock key 43 partially extends out of the front of the lock panel 1, so that the lock key 43 can be moved up and down, thereby driving the movable part 4 to move up and down. In order to facilitate the user to intuitively judge the position of the lock key 43, a schematic area 15 is provided on the periphery of the through hole 14, and the schematic area 15 has the words "OFF" and "ON". When the lock key 43 is in the "OFF" position of the schematic area, it means that the movable part 4 is in the locked position, and the internal body 31 and the external body 32 are in a linkage state. When the lock key 43 is in the "ON" position of the schematic area, it means that the movable part 4 is in the unlocked position, and the internal body 31 and the external body 32 are in an independent active state, that is, it enters a safe state of anti-cat's eye.

[0038] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
