Description

Technical Field

[0001] The utility model relates to a lock, in particular to a sliding cover lock. Background Art

[0002] At present, the application of smart door locks is becoming more and more widespread. Smart door locks generally use touch screens (including capacitive buttons) or physical buttons to input passwords or perform other functional operations. However, this type of interaction method is prone to damage due to bumps and other problems because the interaction interface is exposed. Therefore, smart locks with sliding covers have begun to appear on the market. This type of sliding cover can cover or expose the interaction interface by sliding, and the shielding effect of the sliding cover is used to protect the interaction interface.

[0003] However, the following problem arises: when the user enters the room, he first needs to slide the slider to expose the interactive interface. After successful interaction, the unlocking action is performed. At this time, the lock cylinder rotates to complete the unlocking. After the unlocking is completed, the user needs to reset the slider to put the interactive interface into a protected state again. There is still an inconvenience for users. It is easy to open the door after unlocking and enter the room directly without resetting the slider, which makes the protection of the interactive interface invalid.

[0004] Therefore, the current sliding cover lock needs to be further optimized to make it more convenient for users to use. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a sliding cover lock that is convenient for users to use. The sliding cover can automatically reset after unlocking, avoiding the user forgetting to reset the sliding cover and causing the protection function to fail. At the same time, it also reduces the user's operating steps and makes it more convenient to use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sliding cover lock, comprising a shell, an interactive panel arranged on the shell, a sliding cover arranged on the shell, and a lock core arranged in the shell and associated with the interactive panel or a handle. The sliding cover can be slidably installed on the shell, and the interactive panel can be opened and covered by sliding up and down; a limit piece is also provided on the shell at a position corresponding to the open state of the sliding cover, and the limit piece is linked with the lock core. When the lock core rotates, the limit piece releases the limit on the sliding cover, and the sliding cover slides down and resets under the action of gravity.

[0007] As a further improvement of the utility model, a pull rope is provided on the lock core, one end of the pull rope is fixedly connected to the lock core, and the other end is associated with the limiting member. The lock core pulls the pull rope by rotating and retracts the limiting member to release the limiting effect.

[0008] As a further improvement of the present invention, the limiting member is telescopically arranged on the housing, and an elastic member is arranged between the housing and the limiting member for allowing the limiting member to reset and extend.

[0009] As a further improvement of the present invention, the edge of one end of the limiting member extending out of the shell is provided with a chamfer or a rounded corner along the circumferential direction.

[0010] As a further improvement of the utility model, a groove is provided on the sliding cover at a position corresponding to the limiting member.

[0011] As a further improvement of the present invention, a protrusion is provided on the sliding cover at a position corresponding to the limiting member, and the groove is located at an end of the protrusion corresponding to the limiting member.

[0012] As a further improvement of the present invention, the edge of the raised end portion on the sliding cover is provided with a chamfer or a rounded corner along the circumferential direction.

[0013] As a further improvement of the utility model, a conversion piece is also provided on the shell, which is rotatably connected to the shell, and a first connection part and a second connection part are provided on the conversion piece, and when the conversion piece rotates, the linear speed of the first connection part is greater than that of the second connection part; one end of the pull rope is fixedly connected to the lock core, and the other end is fixedly connected to the first connection part, and the second connection part is also connected to the limit part through a transfer rope. When the lock core rotates, the pull rope pulls the conversion piece to rotate, and pulls the limit part to retract through the transfer rope.

[0014] As a further improvement of the present invention, an elastic component is arranged between the conversion member and the shell. When the conversion member is pulled by the pull rope, the elastic component accumulates elastic force, and after the pull rope is no longer pulled, the elastic component releases the elastic force to reset the conversion member.

[0015] The beneficial effects of the utility model are as follows: the limiter limits the sliding cover, so that the sliding cover is limited when it is in the open state and will not slide down. After the user finishes interacting with the interactive panel, the lock core is rotated by driving components such as a motor, a mechanical key, and a handle, and the rotation of the lock core is used to cooperate with the limiter. After the lock core rotates, the limiter releases the limiting effect on the sliding cover, and the sliding cover can automatically slide down under the action of gravity to reset and re-cover the interactive panel. It is more convenient for users to use, with fewer operating steps, and the protective effect of the sliding cover on the interactive panel is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figure 1-4 As shown,

[0023] A sliding cover lock comprises a shell 1, an interactive panel 2 arranged on the shell 1, a sliding cover 3 arranged on the shell 1, and a lock core 4 arranged in the shell 1 and associated with the interactive panel 2 or a handle. The sliding cover 3 is installed on the shell 1 so as to be slidable up and down, and the interactive panel 2 is opened and covered by sliding up and down. A limiting member 5 is also arranged at a position on the shell 1 corresponding to the open state of the sliding cover 3, and the limiting member 5 is linked with the lock core 4. When the lock core 4 rotates, the limiting member 5 releases the limit on the sliding cover 3, and the sliding cover 3 slides down and resets under the action of gravity.

[0024] The interactive panel 2 can be a mechanical key panel or a touch screen panel, and can be used for the user to unlock and operate functions. The sliding cover 3 slides up and down, and can slide down by gravity.

[0025] When in use, first slide the sliding cover 3 up, and use the limit member 5 to limit it after sliding into place, so that the sliding cover 3 is limited when it is in the open state and will not slide down. After the user finishes interacting with the interactive panel 2, the lock core 4 is rotated by driving components such as a motor, a mechanical key, and a handle, and the rotation of the lock core 4 is used to cooperate with the limit member 5. After the lock core 4 rotates, the limit member 5 releases the limiting effect on the sliding cover 3. At this time, the sliding cover 3 can automatically slide down under the action of gravity to reset, and re-cover the interactive panel 2.

[0026] The above-mentioned limiting member 5 is associated with the lock core 4, and can be implemented specifically by the following scheme:

[0027] 1. The limiter 5 is a connecting rod, one end of which is in contact with or connected to the lock core 4, and the other end of which has a block with a protrusion 22 (used to lock the slide cover 3 in the open state). At the same time, the connecting rod is rotatably installed in the housing 1 to form a lever. The rotation of the lock core 4 is used to pry the connecting rod, thereby allowing the block with the protrusion 22 to leave the slide cover 3, so that the slide cover 3 can slide down under the action of gravity.

[0028] 2. The limiting member 5 is a card block with a protrusion 22 , and the lock core 4 is connected to the card block through a pull rope 6 . When the lock core 4 rotates, it can be pulled and stretched to pull the card block away from the sliding cover 3 .

[0029] The second option is described in detail below:

[0030] The lock core 4 is provided with a pull cord 6, one end of which is fixedly connected to the lock core 4, and the other end is associated with the limiter 5. The lock core 4 rotates and pulls the pull cord 6, and the limiter 5 is retracted to release the limit effect. The limiter 5 in this solution can be manually controlled to lock the sliding cover 3, and when the limit effect is released, the limiter 5 is retracted by the cooperation between the lock core 4 and the pull cord 6.

[0031] In order to make the locking (i.e., limiting the slide cover 3) method more convenient, the limiting member 5 is retractably arranged on the housing 1, and an elastic member 7 is arranged between the housing 1 and the limiting member 5, which is used to reset and extend the limiting member 5. The elastic member 7 can be a spring, and the spring is used to keep the limiting member 5 in an extended state. For example, there is a groove 21 on the slide cover 3, and the groove 21 is used to cooperate with the limiting member 5 for limiting. After the slide cover 3 slides up to the position, the limiting member 5 is inserted into the groove 21 under the action of elastic force to produce a limiting effect. During the sliding process of the slide cover 3, an inclined surface can be arranged at the position corresponding to the limiting member 5, and the inclined surface is used to press down the limiting member 5. After the limiting member 5 is aligned with the groove 21, the limiting member 5 is inserted into the groove 21 under the action of elastic force.

[0032] Of course, instead of providing the inclined surface, the following configuration may be adopted: the edge of one end of the limiting member 5 extending out of the housing 1 is provided with a chamfer or a rounded corner along the circumferential direction.

[0033] The chamfer or rounded corner of the edge of the limiting member 5 is used to form a transition, thereby facilitating the limiting member 5 to be pressed down during the sliding of the slide cover 3, thereby preventing the limiting member 5 from affecting the sliding of the slide cover 3.

[0034] In a further configuration, a groove 21 is provided on the slide cover 3 at a position corresponding to the stopper 5. A protrusion 22 is provided at a position corresponding to the stopper 5 on the slide cover 3, and the groove 21 is located at the end of the protrusion 22 corresponding to the stopper 5. The groove 21 is located on the protrusion 22, which can shorten the distance between the groove 21 and the stopper 5, making it easier for the stopper 5 to cooperate with the groove 21. At the same time, the chamfer or rounded corner of the edge of the stopper 5 can cooperate with the protrusion 22, and the stopper 5 can be pressed down by the chamfer and rounded corner.

[0035] In order to facilitate the cooperation with the limiting member 5 , the edge of the end of the protrusion 22 on the sliding cover 3 is provided with a chamfer or a rounded corner along the circumferential direction.

[0036] The chamfer or rounded corners of the edge of the protrusion 22 cooperate with the chamfer or rounded corners of the edge of the stopper 5 to further alleviate the obstruction problem of the stopper 5. The sliding of the sliding cover 3 is smoother, and the cooperation between the protrusion 22 and the groove 21 is also smoother.

[0037] In a more preferred embodiment, a conversion member 8 is also provided on the shell 1, and the conversion member 8 is rotatably connected to the shell 1, and a first connection part 81 and a second connection part 82 are provided on the conversion member 8, and when the conversion member 8 rotates, the linear speed of the first connection part 81 is greater than that of the second connection part 82; one end of the pull rope 6 is fixedly connected to the lock core 4, and the other end is fixedly connected to the first connection part 81, and the second connection part 82 is also connected to the limit member 5 through the adapter rope 9. When the lock core 4 rotates, the pull rope 6 pulls the conversion member 8 to rotate, and pulls the limit member 5 to retract through the adapter rope 9.

[0038] Since the rotation angle of the lock core 4 is large, the distance that the pull rope 6 is pulled is also large, and the displacement of the limit member 5 itself does not need to be very large. When the required displacement of the limit member 5 is small, it can help reduce the extended length of the limit member 5, which also helps to reduce the thickness of the sliding cover 3 or the panel.

[0039] The conversion member 8 in this solution can use different linear speeds to achieve the conversion of the pulling distance. The first connection part 81 with a larger linear speed cooperates with the pull rope 6, and the second connection part 82 with a smaller linear speed cooperates with the transfer rope 9, so that the pull rope 6 with a larger pulling distance can be converted by the linear speed of the conversion member 8, and a smaller pulling distance can be generated to act on the transfer rope 9, thereby allowing the smaller pulling distance to act on the transfer rope 9 to achieve the conversion effect.

[0040] As an implementation method capable of assisting resetting, an elastic component 7 (a torsion spring may be used) is provided between the conversion component 8 and the shell 1. When the conversion component 8 is pulled by the pull rope 6, the elastic component 7 accumulates elastic force, and after the pull rope 6 is no longer pulled, the elastic component 7 releases the elastic force to allow the conversion component 8 to be reset.

[0041] The conversion member 8 itself can be reset by means of the elastic member 7. On the one hand, it can reset the conversion member 8 to release the transfer rope 9, and allow the limit member 5 to pop out again under the action of the elastic force, preparing for the next locking of the sliding cover 3. On the other hand, it can pull the pull rope 6 to assist in resetting the lock core 4. The limit member 5, as an intermediate member, has a reset function and can coordinate the lock core 4 and the limit member 5 to make the work more stable.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
