[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Embodiment

[0017] Please refer to Figure 1 , Figure 2 and Figure 3 , the present utility model provides a technical solution: a lock mechanism with a sound insulation structure, including a box body 1. The inside of the box body 1 is hollow. A base 2 is provided on the top surface of the box body 1, and a cover plate is provided on the top surface of the base 2. Specifically, the cover plate and the base 2 are connected by a buckle or a screw. The cover plate is a double-layer structure, and a top plate 3 and a bottom plate 4 are sequentially provided on the cover plate from top to bottom. A cavity is formed between the top plate 3 and the bottom plate 4. A plurality of through holes are formed through the top surface of the bottom plate 4 in a penetrating manner, and the internal parts of the lock mechanism are all hollow.

[0018] In this embodiment, the porous structure of the bottom plate 4 can better absorb noise. At the same time, the cavity formed by the double-layer structure of the cover plate has a weakening effect on the transmission of noise. The internal parts of the lock mechanism and the inside of the box body 1 are both hollow, further absorbing and weakening the noise.

[0019] Furthermore, the top plate 3 is provided in a curved shape.

[0020] In this embodiment, the top plate 3 is provided in a curved shape, which is not only beautiful, but also increases the cavity area between the top plate 3 and the bottom plate 4, improving the noise reduction effect.

[0021] Furthermore, a transmission mechanism is provided on the top surface of the base 2. The transmission mechanism includes two transmission rods. Two racks 5 are symmetrically provided between the opposite surfaces of the two transmission rods. A gear 6 is meshed between the two racks 5, and the gear 6 is rotationally connected to the top surface of the base 2 through a rod shaft.

[0022] In this embodiment, the transmission mechanism is cooperated with the rack 5 through the gear 6, which can reduce the noise caused by the friction between transmission parts.

[0023] Furthermore, the top plate 3 and the bottom plate 4 are connected by snap fasteners.

[0024] In this embodiment, the top plate 3 and the bottom plate 4 are connected by snap fasteners, which is convenient for quick installation and disassembly.
