In fig. 1, a half-shell part of a housing 11 is shown, which may be formed by two half-shell boxes or a half-shell and a cover plate in combination, the middle part forming a cavity capable of accommodating other components. One side of the shell 11 is provided with a lock tongue hole, the lock tongue 12 is slidably arranged at a position close to the lock tongue hole in the shell 11, and when in use, the lock tongue 12 can stretch and retract along the lock tongue hole to realize a switch lock. The pull rod 13 is also slidably provided in the housing 11, and one end thereof is connected to the tongue 12, so that sliding of the tongue 12 is controlled by controlling sliding of the pull rod 13. In particular, the pull rod 13 may be driven by a handle on the door or other electrical and magnetic means. One end of the lever 14 is connected to a rotary damper 15 fixed in the housing 11, so that when the lever 14 is rotated by an external force, the rotary damper 15 can apply a varying resistance thereto (the resistance is also greater when the rotation speed of the lever 14 is greater, and the resistance is also smaller when the rotation speed of the lever 14 is smaller), so that the rotation of the lever 14 can be smoothly performed. The other end of the deflector rod 14 is slidably arranged on the pull rod 13, and when the pull rod 13 slides, the deflector rod 14 can be driven to rotate around the rotary damper 15.

When the noise reduction lockset is used, the pull rod 13 is driven to slide, so that the lock tongue 12 can stretch out and draw back in a lock tongue hole to realize the switching function of a lockset foundation, meanwhile, the driving rod 14 can be driven to rotate in the process, and the rotary damper 15 generates variable resistance, so that the process of switching the lock is carried out at a relatively stable speed, the noise of the switching lock process can be reduced, and the noise reduction lockset is ensured not to generate larger noise when in use.

Specifically, in this embodiment, a first clamping groove 131 is provided on one side of the pull rod 13, one end of the shift lever 14 is slidably disposed in the first clamping groove 131, and when the pull rod 13 slides, the side surface of the shift lever 14 abuts against the side surface of the first clamping groove 131, and as the pull rod 13 continues to slide, the end of the shift lever 14 slides in the first clamping groove 131 relative to the first clamping groove 131, and simultaneously, the shift lever 14 rotates around the rotary damper 15 under the pushing of the side wall of the first clamping groove 131. The first catch 131 here serves to receive one end of the lever 14 and to enable it to rotate about the rotary damper 15. Therefore, in other embodiments, a limiting hole capable of accommodating the driving lever 14 may be provided on the pull lever 13, or a pin shaft and a long hole may be provided on the pull lever 13 and the driving lever 14, respectively, and the pin shaft slides in the long hole to achieve connection of the two. The two connection forms can also realize the sliding fit of the deflector rod 14 and the pull rod 13, and simultaneously the pull rod 13 can drive the deflector rod 14 to rotate when sliding.

In this embodiment, a second engaging groove 132 is provided on one side of the tie rod 13, a handle fork 16 is rotatably provided in the housing 11, and a toggle portion 161 is formed on the outer periphery of the handle fork 16 in the second engaging groove 132. After the noise reduction lock is installed on a door, the handle shifting fork 16 is connected with a handle, and the handle shifting fork 16 can be rotated through the handle, so that the shifting part 161 moves in the second clamping groove 132. Referring to fig. 1, if the handle fork 16 is rotated clockwise, the poking portion 161 moves to the right in the drawing in the second clamping groove 132, and after contacting the side wall of the second clamping groove 132, the pull rod 13 can be driven to move to the right in the drawing, so as to retract the lock tongue 12 into the housing 11, thereby realizing unlocking; conversely, if the handle fork 16 is rotated counterclockwise, the pulling portion 161 moves to the left in the drawing in the second clamping groove 132, and after contacting the sidewall of the second clamping groove 132, the pulling rod 13 can be driven to move to the right in the drawing, so that the locking tongue 12 extends out of the housing 11, thereby realizing locking. In other embodiments, a motor may be disposed in the housing 11, and the pull rod 13 may be driven by the motor to slide left and right, so that the switch lock function may be realized.

Further, in this embodiment, a first return spring 17 is further provided in the housing 11, one end of which is connected to the handle fork 16, and the other end of which is fixed in the housing 11. When the handle fork 16 is in the initial position, the first return spring 17 is also in the initial state; after the handle fork 16 rotates clockwise in fig. 1 to move the pull rod 13 to the inner side of the housing 11, the first return spring 17 is driven to be pressed, and at this time, the first return spring 17 applies an acting force to the handle fork 16, so that the handle fork 16 can rotate anticlockwise and return to an initial state after losing an external force. Ensuring that the user rotates the handle fork 16 in either the forward or reverse direction each time the lock is used.

In addition, the noise reduction lockset further comprises a lining plate 19 arranged on one side of the shell 11 and provided with a bolt hole, a through hole opposite to the bolt hole is formed in the middle of the lining plate 19, so that the bolt 12 can conveniently pass through, and first mounting holes 31 are formed in two end parts of the lining plate 19, so that the noise reduction lockset can be conveniently mounted on a door leaf.

The noise-reducing lockset with the structure is suitable for various types of door locks, such as common mechanical door locks and intelligent door locks, and can not generate larger noise when the door lock is opened or closed.

In addition, in this embodiment, the noise reduction lock can be applied to a magnetic door lock after the lock tongue 12 is set as a magnetic attraction type lock tongue. Specifically, the magnetically attracted latch bolt may be made of ferromagnetic metal or a magnet may be provided on the latch bolt 12 that is attracted to the magnet 22 in the buckle box assembly to effect the locking. Correspondingly, the noise reduction lockset also comprises a buckle box assembly, wherein the buckle box assembly comprises a buckle box body 21, a buckle groove 211 capable of accommodating the front end of the lock tongue 12 is formed in one side of the buckle box assembly, and a magnet 22 opposite to the buckle groove 211 and the lock tongue 12 is fixedly arranged on the buckle box body 21. In use, the buckle box component is installed on the door frame, the lock body is partially installed on the door leaf, and when the door leaf is closed, the lock tongue 12 faces the buckle groove 211, so that under the magnetic force of the magnet 22 on the buckle box body 21, the lock tongue 12 can be adsorbed into the buckle groove 211 to complete the locking action.

In the locking process, the lock tongue 12 drives the pull rod 13 to slide, and then drives the deflector rod 14 to rotate, and under the resistance action of the rotary damper 15, the lock tongue 12 can move into the buckling groove 211 at a stable speed, so that no loud noise occurs in the locking process.

Further, in this embodiment, a second return spring 18 is further disposed in the housing 11, one end of the second return spring 18 is connected to the lock tongue 12, the other end is fixed in the housing 11, and applies a force to the lock tongue 12 toward the inside of the housing 11, and the force is smaller than the magnetic attraction force of the magnet 22 in the buckle box assembly to the lock tongue 12. The second return spring 18 has the function that when the door leaf is not in a closed state, the lock tongue 12 can retract into the shell 11 under the action of the second return spring 18, so that the body of a user cannot be scratched or the clothes cannot be hooked, and meanwhile, the door edge cannot be protruded after the lock tongue 12 is retracted, so that the appearance is concise and attractive. In addition, since the elastic force of the second return spring 18 is smaller than the attractive force of the magnet 22, the lock tongue 12 can be attracted into the buckling groove 211 by the magnet 22 after the door leaf is closed, so that the door leaf is closed.

In addition, in order to further reduce noise during locking, a buffer 23 made of a flexible material is provided in the latch slot 211 on the side of the magnet 22 close to the latch tongue 12. When the bolt 12 is absorbed into the buckling groove 211, the bolt is not directly contacted with the bottom surface of the buckling groove 211 or the magnet 22, but is abutted against the softer buffer piece 23, so that noise generated by collision can be reduced, and the locking process is quieter.

Furthermore, in this embodiment, the buffer member 23 is also of a groove-shaped structure, which is similar to the structure of the catching groove 211, and can be disposed in the catching groove 211. The two side walls of the buffer member 23 extend outwards to form a coating portion 231 covering the side edge of the buckle slot 211, and the coating portion 231 can play a role of fixing the buffer member 23, and can prevent the lock tongue 12 from touching the side wall of the buckle slot 211. The lock tongue 12 can not directly contact with the front end face, the side wall and the bottom face of the lock groove 211 when entering the lock groove 211 or after entering the lock groove 211, so that noise in the locking process can be further reduced.

In addition, a plurality of protruding portions 232 are formed on the bottom surface of the buffer member 23, the protruding portions 232 are disposed toward the latch member side, and compared with the case where the front end surface of the latch member 12 is directly abutted against the bottom surface of the buffer member 23, after the protruding portions 232 are disposed, the buffer stroke of the latch member 12 is further increased, and noise generated by touching the latch member 12 and the buffer member 23 can be further reduced.

In this embodiment, a cavity having a second mounting hole 32 at one end is provided at a side of the buckle box body 21 away from the latch tongue 12 for accommodating the magnet 22, and a chuck 212 extending toward the second mounting hole 32 is provided at an end of the buckle box body 21 for limiting the magnet 22. When the cartridge assembly is assembled, the chuck 212 can block the magnet 22 from moving outwardly after the magnet 22 is inserted into the cavity through the second mounting hole 32. This configuration facilitates assembly of the magnet 22 and prevents the magnet 22 from falling off after assembly. In other embodiments, the magnet 22 may be disposed in the slot 211, for example, between the buffer member 23 and the bottom surface of the slot 211, which also serves to limit the magnet 22.

The noise reduction lockset is installed on a door frame when in use, and can be particularly clamped or bolted on the door frame. In this embodiment, a bolted connection is used. Specifically, the two ends of the buckle box body 21 are respectively provided with a long third mounting hole 33 along the horizontal direction, when in use, the noise reduction lockset is fixedly mounted on the door frame through screws penetrating through the long third mounting holes 33, and the long third mounting holes 33 are convenient for horizontally adjusting the horizontal position of the buckle box assembly, so that the buckle box assembly is convenient for being opposite to the lock tongue 12 on the door.

Further, in this embodiment, the buckle box assembly further includes a mounting plate 24, the buckle box body 21 is fixedly connected to the mounting plate 24 through bolts penetrating through the third mounting holes 33, the fourth mounting holes 34 are provided at two ends of the mounting plate 24, and a through hole through which the locking bolt 12 passes is provided in the middle of the mounting plate 24. Through setting up this mounting panel 24, can remove the hookup location of this knot box subassembly with the door frame to both ends, can not increase the length of detaining box body 21 when improving installation stability, in addition, also be convenient for add other decorative structure in the outside. For example, in this embodiment, a decorative plate 25 is also fastened to the outer side of the mounting plate 24, and has the same shape as the mounting plate 24, and a through hole is provided in the middle for the bolt 12 to pass through. After the decorative plate 25 is arranged, the structure such as a screw on the mounting plate 24 can be covered, so that the appearance is more concise.

In addition, the color of the decorative plate 25 can be adjusted to make the buckle box assembly more easily integrated with the door frame. For example, a color plate 26 is attached to the outer side of the decorative plate 25. The color matching plate 26 is connected to one side of the decorative plate 25 far away from the buckle box body 21 through an adhesive layer 27, a through hole for the bolt 12 to pass through is arranged in the middle of the color matching plate, and the noise reduction lockset and the door frame can be integrated through adhesion of the color matching plates 26 with different colors.
