Description

Technical Field

[0001] This utility model relates to the field of elevator cars, and in particular to an elevator car with sound insulation function. Background Technology

[0002] The elevator car is an important component of the elevator system used to transport passengers and goods. The elevator car consists of a car frame and a car body. The car frame is a load-bearing structural component, composed of upper beams, lower beams, vertical beams, and tie rods, and is generally made of channel steel or steel plate. Its function is to fix and suspend the car and guide the car to move up and down along the guide rails. The car body consists of the car floor, car walls, car top, and car doors, etc. The car floor frame is usually welded from channel steel and angle steel.

[0003] Since existing elevator cars are usually made of steel, when the elevator car runs quickly inside the elevator shaft, noise is generated due to factors such as friction of the guide rails, operation of the traction machine, airflow, and the usage environment. This noise is transmitted into the elevator car and affects the comfort of using the elevator car, thus having certain defects. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-4 The image shows an elevator car with sound insulation.

[0037] Example 2

[0038] The system includes a car shell 1, a snap-fit ​​component 2, a sound insulation unit 3, and a locking assembly 4. The snap-fit ​​component 2 is fixedly connected to the outside of the car shell 1. The sound insulation unit 3 is disposed on the outside of the car shell 1, and the outer side of the sound insulation unit 3 is slidably snapped into the snap-fit ​​component 2. The snap-fit ​​component 2 has an L-shaped cross-section, so that the snap-fit ​​component 2 can wrap and bind the outer side of the sound insulation unit 3. The sound insulation unit 3 is used to provide sound insulation protection for the car shell 1. The locking assembly 4 is disposed on the car shell 1 and is used to snap and lock the sound insulation unit 3. Under the constraint of the locking assembly 4, the sound insulation unit 3 cannot slide relative to the snap-fit ​​component 2, thereby ensuring the stability of the sound insulation unit 3 installed on the outside of the car shell 1, so that the sound insulation unit 3 provides sound insulation protection for the car shell 1.

[0039] Specifically, the sound insulation unit 3 includes a fixed housing 31, an asbestos board 32, a corrugated board 33, and a rubber board 34. The side of the fixed housing 31 is slidably engaged with the snap-fit ​​piece 2. The corrugated board 33 is fitted inside the fixed housing 31, and the corrugated board 33 can form a sound insulation chamber inside the fixed housing 31. One side of the rubber board 34 is in contact with the corrugated board 33. The asbestos board 32 is placed inside the fixed housing 31 and wraps around the rubber board 34 and the corrugated board 33. Both the rubber board 34 and the asbestos board 32 have certain sound insulation and sound absorption properties, thereby providing sound insulation protection for the car body 1 again.

[0040] Furthermore, the locking assembly 4 includes a connecting plate 41 and a locking rod 42. The connecting plate 41 is disposed on the car shell 1. One end of the locking rod 42 is fixedly connected to the connecting plate 41. The outer wall of the locking rod 42 is slidably inserted into the car shell 1. The sound insulation unit 3 is provided with a locking groove that matches the locking rod 42. The locking rod 42 is engaged with the locking groove to lock and limit the sound insulation unit 3. By pulling out the locking rod 42, the sound insulation unit 3 can be slidably separated from the engaging member 2.

[0041] Furthermore, the locking assembly 4 also includes a connecting housing 43 and a limiting spring 44. The side of the connecting housing 43 is fixedly connected to the car housing 1. The connecting plate 41 is slidably sleeved inside the connecting housing 43. The limiting spring 44 is located inside the connecting housing 43. One end of the limiting spring 44 is pressed against the connecting plate 41. The limiting spring 44 can exert an elastic compressive force on the locking rod 42 through the connecting plate 41, thereby ensuring the stability of the locking rod 42 and the sound insulation unit 3. The locking assembly 4 also includes a handle plate 45 and a fixing rod 46. The handle plate 45 is located outside the connecting housing 43. The outer wall of the fixing rod 46 is slidably sleeved with the connecting housing 43. The end of the fixing rod 46 is fixedly connected to the handle plate 45 and the connecting plate 41. The limiting spring 44 is slidably sleeved outside the fixing rod 46. By pulling the handle plate 45 away from the connecting housing 43, the handle plate 45 can drive the connecting plate 41 to move through the fixing rod 46, thereby unlocking the locking rod 42.

[0042] Example 2

[0043] Based on Embodiment 1, the locking assembly 4 further includes a limiting post 47, a plug hole, a limiting member 48, and a hinge member 49. The limiting post 47 is fixedly connected to the side of the connecting plate 41 away from the locking rod 42. When the connecting plate 41 is pulled by the handle plate 45, the limiting post 47 fits against the inner wall of the connecting housing 43, which can limit the connecting plate 41 and prevent the connecting plate 41 from causing pressure damage to the limiting spring 44. The plug hole is opened on the outside of the connecting housing 43. The limiting member 48 is rotatably connected to the handle plate 45 through the hinge member 49. The end of the limiting member 48 has a notch corresponding to the plug hole. So when the handle plate 45 is pulled, the limiting member 48 can be rotated so that the notch at one end of the limiting member 48 is engaged with the plug hole, thereby limiting the handle plate 45 and keeping the locking rod 42 in a stable state and separated from the sound insulation unit 3, thus facilitating the disassembly or installation of the sound insulation unit 3.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
