Description

Technical Field

[0001] This application relates to the technical field of tissue boxes, and in particular to a lock and a tissue box. Background Art

[0002] A tissue box is a container for storing tissues. It is usually designed in the shape of a box for convenient storage and access of tissues.

[0003] The existing Chinese patent with the publication number CN207356023U discloses a tissue box with a lock, which includes a box body. A paper-taking opening is provided on the box body. The box body includes a front cover and a rear seat. The front cover includes a box cover that can be opened laterally and a panel. The box cover and the panel are arranged side by side left and right. The side of the box cover is hinged to the rear seat. A lock mechanism for connecting with the rear seat is provided at the top of the box cover. The lock mechanism includes a lock body provided at the top of the box cover and a lock groove provided on the inner wall of the top of the rear seat. The lock body includes a lock core, a lock hole, a lock shell and a lock hook. One end of the lock hook is in linkage cooperation with the lock core, and the other end can hook the lock groove. The lock hook can rotate with the lock core and has a first position for hooking the lock groove and a second position for separating from the lock groove. The paper-taking opening is provided at the bottom of the box body.

[0004] The above-mentioned tissue box with a lock locks the rear seat through the lock structure provided at the top of the box cover, making the box cover unable to be opened and preventing people from taking away tissues at one time. However, the above-mentioned tissue box with a lock has some disadvantages. For example, the existing locks mostly use a key to unlock, and it cannot be opened without a key, which is inconvenient for places with low anti-theft requirements and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a lock and a tissue box for convenient unlocking.

[0006] A lock provided by this application adopts the following technical solution: It includes a lock tongue and an active component for driving the lock tongue to slide. The active component includes a base and a lock core slidably connected to the base. The lock core is connected to the base through an elastic member. A linkage structure for synchronously sliding the lock core and the lock tongue is connected between the lock core and the lock tongue.

[0007] By adopting the above technical solution, when pressing the lock core in the direction close to the base, the elastic member is compressed and undergoes elastic deformation. The lock tongue moves with the movement of the lock core through the linkage structure. When the lock core is released, the elastic member elastically returns, and the elastic member forces the lock core to slide in the direction away from the base, facilitating unlocking.

[0008] Optionally, the lock tongue includes an abutting portion and a clamping portion. The abutting portion is in contact with the lock core. The linkage structure includes a limiting block connected to the lock core and a limiting area for clamping and cooperating with the limiting block. The limiting area is provided on the abutting portion.

[0009] By adopting the above technical solution, when the lock core slides toward the direction close to the base, the lock core abuts against the abutment part and drives the abutment part to slide toward the direction close to the base. When the lock core slides toward the direction away from the base, the limit block abuts against the inner wall of the limit area and drives the abutment part to slide toward the direction away from the base, thereby realizing that the lock tongue moves with the movement of the lock core.

[0010] Optionally, the lock core is rotatably connected to the abutment portion, the limiting area is an arc-shaped groove, the limiting block is slidably matched with the arc-shaped groove, the abutment portion is provided with a clearance cavity for the limiting block to pass through, the clearance cavity is connected to the arc-shaped groove, and the base is connected to a limiting column corresponding to the clearance cavity.

[0011] By adopting the above technical solution, the lock core rotates relative to the abutment portion, so that the limit column corresponds to the limit block or the limit column and the limit block are staggered, thereby realizing the switching of two gears. When the limit column corresponds to the limit block, the limit column restricts the sliding of the limit block toward the base, thereby restricting the lock tongue from being separated from the engaging groove. When the limit column and the limit block are staggered, the limit column corresponds to the clearance cavity, and when the lock core moves, the limit column is locked into the clearance cavity, so that the lock tongue can be separated from the engaging groove.

[0012] Optionally, at least two of the limit blocks are connected to the lock core, and the number of the limit areas is the same as the number of the limit blocks.

[0013] By adopting the above technical solution, multiple limit blocks cooperate with corresponding limit grooves, which increases the contact area between the limit blocks and the lock tongue and improves the effect of the limit blocks driving the lock tongue to move.

[0014] Optionally, the lock core is provided with a lock hole.

[0015] By adopting the above technical solution, it is convenient for the user to insert the key into the lock hole to drive the lock core to rotate.

[0016] Optionally, the lock core is provided with a sliding column, the base is provided with a sliding hole for slidingly cooperating with the sliding column, and the sliding column is connected to a limiting member for limiting the sliding column from being separated from the sliding hole.

[0017] By adopting the above technical solution, during the sliding process of the lock core, the sliding cooperation between the sliding column and the sliding hole plays a guiding and limiting role in the sliding of the lock core, thereby improving the sliding stability of the lock core. The limiting member limits the sliding column from escaping from the sliding hole during the sliding process, thereby improving the sliding stability of the lock core.

[0018] Optionally, the limiting member is a screw threadedly connected to the sliding column, the screw is connected to a convex ring for abutting against the base, and the sliding hole is located between the convex ring and the lock core.

[0019] By adopting the above technical solution, when the lock core slides away from the base, the screw rod and the convex ring move along with the movement of the lock core. During the movement, the convex ring abuts against the base, thereby restricting the sliding column from disengaging from the sliding hole.

[0020] Optionally, the limiting member is a snap ring detachably connected to the sliding column. The snap ring is in a C shape, and the sliding hole is located between the snap ring and the lock core.

[0021] By adopting the above technical solution, when the lock core slides away from the base, the snap ring moves along with the movement of the lock core. During the movement, the snap ring abuts against the base, thereby restricting the sliding column from disengaging from the sliding hole.

[0022] Optionally, the sliding column is provided with a receiving groove for the snap ring to snap into.

[0023] By adopting the above technical solution, the snap ring snaps into the receiving groove, and the outer surface of the snap ring fits against the inner wall of the receiving groove. The inner wall of the receiving groove restricts the movement of the snap ring, thereby improving the stability of the snap ring installed on the sliding column.

[0024] A tissue box includes a box body, including a back plate, a box body and a lock. The box body is rotatably connected to the back plate. The box body is provided with an installation cavity and a tissue extraction channel communicating with the installation cavity. The lock is installed on one of the box body and the back plate, and a clamping groove for clamping and cooperating with the lock tongue is provided on the other of the box body and the back plate.

[0025] By adopting the above technical solution, the back plate is installed on one side of a wall or some object. When it is necessary to replenish the tissues in the installation cavity, the lock tongue is disengaged from the clamping groove through the active component, unlocking the box body from the back plate, driving the box body to rotate, exposing the opening of the installation cavity for tissue replenishment. After replenishing the tissues into the installation cavity, rotate the box body back to its original position, and the lock tongue is snapped into the clamping groove through the active component to fix the box body to the back plate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Press the lock core in the direction close to the base, the elastic member is compressed to generate elastic deformation, and the lock tongue moves along with the movement of the lock core through the linkage structure. Release the lock core, the elastic member elastically resets, and the elastic member forces the lock core to slide away from the base, facilitating unlocking.

[0028] 2. The lock core rotates relative to the abutment portion, so that the limit column corresponds to the limit block or the limit column and the limit block are staggered, realizing the switching of two gears. When the limit column corresponds to the limit block, the limit column restricts the sliding of the limit block toward the base, thereby limiting the lock tongue from disengaging from the engaging groove. When the limit column and the limit block are staggered, the limit column corresponds to the clearance cavity, and when the lock core moves, the limit column is stuck in the clearance cavity, so that the lock tongue can be disengaged from the engaging groove.
