The car is generally composed of main components such as the car bottom, car walls, car roof, and car doors. It is the car body component used by the elevator to carry passengers or cargo and other loads. The car walls generally need to be soundproofed.

[0003] The prior art (Announcement No.: CN 213059797 U) discloses a sound insulation and noise reduction structure for an elevator car, comprising an elevator car body, wherein panels are fixedly connected to the left and right sides of the inner surface of the elevator car body through sponge sound-absorbing panels, two movable columns are fixedly connected to the top and bottom of one side of the two panels, two movable grooves are provided at the top and bottom of the left and right sides of the inner surface of the elevator car body, one end of the movable column is fixedly connected to the inner surface of the movable groove through a spring member, side grooves are provided on the upper and lower sides of the inner surface of the movable groove, and a sliding rod is fixedly connected to the inside of the side groove.

[0004] Although the above patent can greatly absorb the noise generated by the elevator car through the installation of the sponge sound-absorbing board to achieve the noise reduction effect, and can achieve the shock absorption of the panel in combination with the spring parts, sliding rods, sliders, guide columns and springs, and can further increase the elasticity between the panel and the sponge sound-absorbing board to further achieve the absorption of noise, there are the following disadvantages. When the sponge sound-absorbing board is initially assembled, it is necessary to use blocks and screws to fix the sponge sound-absorbing board, and the screws need to be tightened. The operation is cumbersome and has many operating steps, which affects the installation efficiency and needs further improvement. For this reason, we propose a sound insulation layer connection structure for an elevator car. Utility Model Content

[0005] The main purpose of the utility model is to provide a sound insulation layer connection structure for an elevator car, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The locking component and the fixing component cooperate to improve the installation efficiency of the sound insulation board. When in use, align the rectangular slot with the rectangular block, and drive the circular block to move backward through the sound insulation board. When the circular block moves backward, the circular block squeezes the guide block through the inclined surface, so that the two guide blocks move away from each other. When the rear end of the circular block contacts the rear wall of the rectangular slot, the circular block no longer squeezes the guide block. The two guide blocks are respectively moved closer to each other by the elastic force of the two springs, so that the circular block falls into the two fixing slots for fixing, and the sound insulation board can be fixed. The operation is simple and the operation steps are few. It only needs to push the sound insulation board backward, which improves the installation efficiency.

[0016] 2. The guide rod and the guide hole can be used to facilitate the installation of the sound insulation board. During installation, the guide rod can be inserted into the guide hole first to guide the movement of the sound insulation board, so that the rectangular slot can be quickly aligned with the rectangular block, reducing the time required for subsequent installation and alignment, and further improving work efficiency.
