Referring to fig. 1 to 3, the low noise buckle box assembly of this embodiment includes a buckle box body 1, a magnet 2 and a buffer pad 3. Wherein, one side of the buckle box body 1 is provided with a first cavity 11, and one side of the first cavity 11 is provided with a first through hole 41 into which the lock tongue 51 can extend. The cushion pad 3 is fixed in the first cavity 11 and comprises a fixing layer 31, a cushion layer 33 and a number of connecting layers 32. Wherein, the fixed layer 31 is fixedly connected in the first cavity 11, two ends of the connecting layer 32 are respectively connected to the fixed layer 31 and the buffer layer 33, and the buffer layer 33 faces the first through hole 41. The buffer layer 33 and the connection layer 32 are made of flexible material in this embodiment, and are capable of buffering the latch bolt 51 that is hit thereon. In addition, the fixing layer 31, the buffer layer 33 and the connecting layer 32 may be integrally formed, so that the cushion pad 3 can be manufactured conveniently. The magnet 2 is arranged on the buckle box body 1 and is positioned on one side of the cushion pad 3 far away from the first through hole 41 and used for adsorbing the magnetic spring bolt 51.

The low-noise buckle box assembly in the embodiment is fixed on a door frame when in use, after the door is closed, the magnetic attraction type lock tongue 51 in the lock body on the door leaf can be adsorbed into the first cavity 11, the lock tongue 51 firstly touches the buffer layer 33 in the process, then the buffer layer 33 moves inwards, the connecting layer 32 is pressed and bent, the speed of the lock tongue 51 can be gradually reduced, finally, the lock tongue 51 is stably adsorbed by the magnet 2, and larger noise cannot be generated in the process.

In this embodiment, a plurality of connection layers 32 are symmetrically disposed between the fixing layer 31 and the buffer layer 33. Referring to fig. 2 in detail, the cushion pad 3 includes four connection layers 32, the four connection layers 32 are obliquely arranged, and two connection layers 32 on the upper side and two connection layers 32 on the lower side are symmetrically arranged, so that when the cushion layer 33 is extruded by the lock tongue 51, the cushion pad can move along with the whole of each connection layer 32 to one side of the fixed layer 31, and no horizontal deviation or different partial movement amplitude occurs, so that the lock tongue 51 can move stably.

The fixing layer 31 is clamped on the buckle box body 1 in this embodiment, specifically, two first clamping holes 63 are formed on the buckle box body 1, two first clamping heads 61 are formed on the fixing layer 31, and when the low-noise buckle box assembly is assembled, the cushion pad 3 can be fixedly installed in the first cavity 11 by inserting the first clamping heads 61 into the first clamping holes 63. Wherein, two first chucks 61 are provided at both ends of the fixing layer 31, and two first chuck holes 63 are provided at both ends of the first cavity 11, so that the cushion pad 3 can be fixed relatively stably.

When the low noise fastening box assembly is assembled, the second clamping head 62 can block the magnet 2 from moving outwards after the magnet 2 is inserted into the second cavity 12 through the first mounting hole 71. The structure is convenient for assembling the magnet 2, and the magnet 2 is not easy to fall off after the assembly is completed. In other embodiments, the magnet 2 may be disposed in the first cavity 11, for example, between the fixing layer 31 and the bottom surface of the first cavity 11, which also can perform the function of limiting the magnet 2.

The low-noise buckle box component 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, both ends of the buckle box body 1 are provided with long second mounting holes 72 along the horizontal direction, when in use, the low-noise buckle box assembly is fixedly mounted on the door frame through screws penetrating through the long second mounting holes 72, and the horizontal position of the low-noise buckle box assembly is conveniently adjusted horizontally, so that the low-noise buckle box assembly is conveniently opposite to the lock tongue 51 on the door.

Further, in this embodiment, the low noise buckle box assembly further includes a mounting plate 81, the buckle box body 1 is fixedly connected to the mounting plate 81 through bolts penetrating through the second mounting holes 72, the third mounting holes 73 are provided at both ends of the mounting plate 81, and the second through hole 42 through which the locking bolt 51 can pass is provided in the middle of the mounting plate 81. Through setting up this mounting panel 81, 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 1 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 84 is also fastened to the outer side of the mounting plate 81, and has the same shape as the mounting plate 81, and a second through hole 42 through which the lock tongue 51 passes is provided in the middle. The decorative plate 84 can cover the screw and other structures on the mounting plate 81, so that the appearance is more concise.

In addition, the low noise box assembly can be more easily integrated with the door frame by adjusting the color of the trim panel 84. For example, a color plate 83 is attached to the outside of the decorative plate 84. The color matching plate 83 is connected to one side of the decorative plate 84 far away from the buckle box body 1 through the bonding layer 82, the middle part of the color matching plate is provided with a second through hole 42 through which the lock tongue 51 can pass, and the low-noise buckle box assembly and the door frame can be integrated through bonding the color matching plates 83 with different colors.

In addition, in this embodiment, a lock is disclosed, see fig. 4-5 b in detail, which uses the low noise buckle box assembly as described above, and further includes a lock body structure installed on a door in use, wherein one side of the lock body structure is provided with a magnetic spring bolt 51, when the spring bolt 51 faces the first through hole 41, the magnetic spring bolt 51 can be adsorbed into the first cavity 11 by the magnet 2 to realize automatic locking, and no loud noise is generated in the locking process.

The lock further comprises a cover plate 52 clamped on the side end surface of the door body 9, wherein the middle part of the cover plate is provided with a third through hole 43 through which the lock tongue 51 can pass, and when the lock tongue 51 is not adsorbed into the first cavity 11, the front end surface of the lock tongue 51 does not exceed the outer side surface of the cover plate 52. The cover plate 52 can hide the lock tongue 51 to a certain extent, so that a user cannot easily perceive the lock tongue 51 from the side surface, and can hide the structures such as screws on the side surface of the lock body structure, and meanwhile, the lock body structure is easy to integrate with the side surface of the door body 9, so that the lock body structure is more suitable for extremely simple aluminum frame doors. In addition, since the lock tongue 51 is not exposed when not closed, collision, scratch or hooking to the body or clothes is not caused, and collision with the door frame when the door is closed is not caused.

In another embodiment, another lock is disclosed, and in combination with fig. 6a and 6b, unlike the lock in fig. 5a and 5b, the lock further has a decorative frame 53 clamped in the third through hole 43, the middle part of the decorative frame 53 is provided with a fourth through hole 44 through which the lock tongue 51 passes, and the front end surface of the lock tongue 51 does not exceed the outer side surface of the decorative frame 53. The lock tongue 51 can be hidden to a certain extent by the decorative frame 53, so that the outer side of the lock is more attractive.
