Telescopic car wall

Abstract

This utility model relates to a telescopic car wall, including a car wall body. Both sides of the car wall body are horizontally slidably connected to aluminum alloy adjusting strips. Each aluminum alloy adjusting strip has an integrally bent decorative portion on both sides, which contacts the surface of the car wall body. Multiple adjusting components are equidistantly installed between the aluminum alloy adjusting strips and the car wall body. This utility model allows one end of an external hexagonal screw to move horizontally in a straight line along the side of the car wall body by rotating it. At this time, a spring can extend or shorten according to the axial horizontal movement of the external hexagonal screw, thereby dynamically adjusting the straight-line distance between the side of the car wall body and the aluminum alloy adjusting strips. This allows the overall distance between the two aluminum alloy adjusting strips to be changed, thus achieving lateral telescopic extension and retraction of the entire car wall body, facilitating corresponding adjustment of the total length of the car wall during installation.

Description

Technical Field

[0001] This utility model relates to the field of elevator car wall technology, specifically to a telescopic car wall. Background Technology

[0002] Elevator cars with different loads use car walls of different specifications. The car walls usually include car side walls and car rear walls, and both car side walls and car rear walls are made up of multiple car wall panels spliced ​​together in sequence.

[0003] Due to market demand, large-tonnage elevators are now common, and the elevator car dimensions are correspondingly larger. Some customers, for practical needs, require the door opening width to be the same as the car width. In this case, the car side walls will be relatively more numerous. Taking 10 car wall panels, each 500mm wide, as an example, with a car depth of 5000mm, however, in actual production, deviations in the bending process or steel plate powder coating process can result in a total length of 5005mm or 4995mm after assembling 10 panels. The theoretical gap between the elevator door and the car wall is 4mm. Therefore, when the car width and door opening width are the same, if the above situation occurs, friction will occur between the elevator door and the car wall, potentially causing malfunctions during elevator operation.

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a telescopic car wall, including a car wall body 1, with aluminum alloy adjusting strips 2 horizontally slidably connected to both sides of the car wall body 1, and decorative parts 3 integrally bent on both sides of the aluminum alloy adjusting strips 2, the decorative parts 3 contacting the surface of the car wall body 1, and multiple adjusting components 4 equidistantly installed between the aluminum alloy adjusting strips 2 and the car wall body 1 to drive the aluminum alloy adjusting strips 2 to drive the decorative parts 3 to move horizontally on the side of the car wall body 1.

[0024] Please see Figure 1 and Figure 2 As described in the background art, in this embodiment, the width of the car wall body 1 is 470mm. However, when installing the entire car wall, a car wall with a width of 505mm is required. Therefore, the aluminum alloy adjusting trim 2 can be driven to move horizontally on the side of the car wall body 1 by adjusting the component 4, so that the overall width of the two aluminum alloy adjusting trim 2 reaches 505mm. Finally, the car wall body 1 can be fixedly connected to the car walls on both sides to achieve the most reasonable installation effect, and there will be no friction between the elevator door and the car wall.

[0025] The adjustment assembly 4 includes an external hexagonal screw 41, a hexagonal nut 42, and an elastic element 43. One end of the external hexagonal screw 41 passes through the aluminum alloy adjustment trim 2 and is threadedly connected to the car wall body 1. The hexagonal nut 42 is threadedly connected to the external hexagonal screw 41, and the side of the hexagonal nut 42 abuts against the inner wall of the car wall body 1. The elastic element 43 is installed between the aluminum alloy adjustment trim 2 and the car wall body 1. The elastic element 43 is a spring, which is sleeved on the external hexagonal screw 41, and the two ends of the spring abut against the surfaces of the aluminum alloy adjustment trim 2 and the car wall body, respectively.

[0026] Please see Figure 3 and Figure 4 In this embodiment, the hexagonal nut 42 is limited by a wrench or other object, and then the external hexagonal screw 41 is rotated so that the external hexagonal screw 41 is axially translated on the side of the car wall body 1. As mentioned above, if it is necessary to extend the overall width of the car wall body 1, then the external hexagonal screw 41 needs to be turned so that it is axially translated away from the car wall body 1. At this time, the external hexagonal screw 41 can separate from the aluminum alloy adjustment strip 2, but the spring can drive the aluminum alloy adjustment strip 2 to move synchronously through its own elasticity, so that the external hexagonal screw 41 abuts against the aluminum alloy adjustment strip 2 again, thereby increasing the overall width of the two aluminum alloy adjustment strips 2, so as to connect the car wall body 1 with other car walls. The axial translation distance of the external hexagonal screw 41 is -5mm to 7mm.

[0027] It should be noted that the connection between the car wall body 1 and other car walls is made through side holes. The specific connection method is a technical means well known to those skilled in the art and will not be described in detail here.

[0028] The surface of the aluminum alloy adjusting trim strip 2 is provided with a groove 5. One side of the driving end of multiple external hexagonal screws 41 abuts against the inner wall of the groove 5 through a washer 6. The thickness of the driving end of the external hexagonal screws 41 is less than the depth of the groove 5.

[0029] Please see Figure 4 By setting the groove 5, when the car wall body 1 is connected to other car walls, the installation will not be affected by the external hexagonal screw 41 protruding from the surface of the aluminum alloy adjustment trim 2.

[0030] Both ends of the car wall body 1 are horizontally fixed with end caps 7, and a main reinforcing rib 8 is vertically fixed between the two end caps 7. The main reinforcing rib 8 is fixedly installed on the surface of the car wall body 1, and a connecting plate 9 is fixedly installed on the surface of the main reinforcing rib 8. Both ends of the connecting plate 9 are fixedly connected to the car wall body 1 with secondary reinforcing ribs 10.

[0031] Please see Figure 1 and Figure 5The mechanical strength of the car wall body 1 can be increased by setting the end cap 7, the main reinforcing rib 8 and the secondary reinforcing rib 10, thereby increasing the stability.

[0032] The secondary reinforcing rib 10 includes a first straight segment 101, a second straight segment 102, a third straight segment 103, a first inclined segment 104, a second inclined segment 105, and a fourth straight segment 106. One end of the first straight segment 101 is fixedly connected to the connecting plate 9, and one end of the third straight segment 103 is fixedly connected to the car wall body 1. The first straight segment 101 and the second straight segment 102 are fixedly connected through the first inclined segment 104, and the second straight segment 102 and the third straight segment 103 are fixedly connected through the second inclined segment 105. The fourth straight segment 106 is fixedly installed between the first inclined segment 104 and the second inclined segment 105.

[0033] Please see Figure 5 In this embodiment, the main reinforcing rib 8 is located in the middle part of the car wall body 1, which can increase the longitudinal support performance of the car wall body 1. The secondary reinforcing rib 10 can increase the lateral support performance of the car wall body. The second straight segment 102 and the fourth straight segment 106 can be set as a skeleton on the car wall body 1, which, together with the main reinforcing rib 8, greatly increases the overall support performance.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
