[0034] According to the exemplary embodiment of the utility model, please refer to Figures 1-3 , provide a kind of connecting device for the side wall of elevator car. Car includes the side wall 1 and cover plate 2 being arranged in parallel. Connecting device includes connecting portion 5, limiting portion 3 and buffer portion 4. Connecting portion 5 is configured to pass through side wall 1 and cover plate 2. Limiting portion 3 is sleeved on connecting portion 5, and extend towards the inside of side wall 1 (the side of side wall 1 and cover plate 2 facing each other) passing through cover plate 2. Buffer portion 4 is covered in the outside of limiting portion 3, the inside end of buffer portion 4 (the end of buffer portion 4 facing side wall 1) extends beyond the inside end of limiting portion 3 (the end of limiting portion 3 facing side wall 1), and abuts with the inside of side wall 1, buffer portion 4 is configured to respond to the outside end of limiting portion 3 and buffer portion 4 (the end of limiting portion 3 exposed to cover plate 2, the end of buffer portion 4 exposed to cover plate 2) being extruded respectively by both ends of connecting portion 5 and the outside of side wall 1 (the side of side wall 1 and cover plate 2 mutually away from), the part of buffer portion 4 beyond limiting portion 3 deforms, so that limiting portion 3 and the inside end of buffer portion 4 abut with the inside of side wall 1 simultaneously, to combine side wall 1 and cover plate 2, and buffer vibration transmitted between side wall 1 and cover plate 2.

The specific implementation can be opposite to the setting direction of the limiting portion 3 and the buffer portion 4 in the embodiment, and will not be described here again. Figure 3

[0038] Figure 4 FIG. 1 is a perspective view of the connecting device in the embodiment of the utility model along the axial direction; Figure 5 FIG. 2 is a perspective view of the connecting device in the embodiment of the utility model applied to the combination of the cover plate and the side wall of the car, and the connecting device is in the uncompressed state; Figure 6 FIG. 3 is a perspective view of the connecting device in the embodiment of the utility model applied to the combination of the cover plate and the side wall of the car, and the connecting device is in the compressed state.

[0039] In some exemplary embodiments, reference can be made to Figures 4-6 ​, a recess 411 extending in the circumferential direction is formed on the outer wall of the buffer portion 4 near the inner side end (the end of the limiting portion 3 facing the side wall 1) of the buffer portion 4, which is adapted to allow the portion of the inner side end (the end of the buffer portion 4 facing the side wall 1) of the buffer portion 4 protruding beyond the limiting portion 3 to contract in the axial direction to generate deformation, so that the inner side end (the end of the buffer portion 4 facing the side wall 1, the end of the limiting portion 3 facing the side wall 1) of the buffer portion 4 and the limiting portion 3 simultaneously abut against the inner side of the side wall 1, in the case where the buffer portion 4 is pressed in the axial direction.

[0040] By the above arrangement, in the state where the connecting portion 5 presses the outer side end (the end of the limiting portion 2 exposed to the cover plate 1, the end of the buffer portion 4 exposed to the cover plate 1) of the limiting portion 2 and the buffer portion 4, and the outer side (the side of the side wall 1 facing away from the cover plate 2) of the side wall 1, the buffer portion 4 is pressed in the axial direction, the buffer portion 4 collapses at the position of the recess 411, so that the portion of the inner side end of the buffer portion 4 protruding beyond the limiting portion 3 contracts in the axial direction to generate deformation, and contracts to the plane where the inner side end of the buffer portion 4 and the inner side end of the limiting portion 3 are coplanar, so that the inner side end of the buffer portion 4 and the limiting portion 3 simultaneously abut against the inner side of the side wall 1, to combine the cover plate 2 with the side wall 1.

[0041] In some example embodiments, referring to Figures 4-6 The limiting portion 3 includes a limiting cylinder 32 and a first flange 31. The limiting cylinder 32 is sleeved on the connecting portion 5 and extends towards the inner side of the side wall 1 through the cover plate 2, the buffer portion 4 is wrapped outside the limiting cylinder 32, and the inner side end (the end of the buffer portion 4 facing the side wall 1) of the buffer portion 4 extends beyond the inner side end (the end of the limiting cylinder 32 facing the side wall 1) of the limiting cylinder 32. The first flange 31 extends radially outward at the outer side end (the end of the limiting cylinder 32 exposed to the cover plate 2) of the limiting cylinder 32, serving as the outer side end of the limiting portion 3.

[0042] In the present embodiment, the limiting cylinder 32 is sleeved on the connecting portion 5, the buffer portion 4 is wrapped outside the limiting cylinder 32, and the inner side end of the buffer portion 4 extends beyond the inner side end of the limiting cylinder 32, so that the limiting cylinder 32 plays a role in supporting the buffer portion 4, and in the state where the connecting portion 5 presses the outer side end (the end of the buffer portion 4 exposed to the cover plate 2, the outer side (the side of the side wall 1 facing away from the cover plate 2) of the side wall 1) of the first flange 31 and the buffer portion 4, respectively, limits the maximum deformation of the portion of the inner side end of the buffer portion 4 protruding beyond the limiting portion 3 to generate deformation.

[0043] In some example embodiments, referring to Figures 4-6The buffer part 4 comprises a buffer cylinder 41 and a second flange 42. The buffer cylinder 41 is wrapped outside the limiting cylinder 32 and extends beyond the inner end of the limiting cylinder 32 (the end of the limiting cylinder 32 facing the side wall 1) and abuts the inner side of the side wall 1. The second flange 42 extends radially outward at the outer end of the buffer cylinder 41 (the end of the buffer cylinder 41 exposed to the cover plate 2) and is located between the outer side of the cover plate 2 and the first flange 31.

[0044] According to the above arrangement, the second flange 42 extends radially outward at the outer end of the buffer cylinder 41 and is located between the outer side of the cover plate 2 and the first flange 31, so that the first flange 31 abuts the second flange 42 in the axial direction. The limiting cylinder 32 serves to support the buffer cylinder 41. At the same time, the buffer cylinder 41 is pressed in the axial direction in the state that the first flange 31 and the outer side of the side wall 1 (the side of the side wall 1 away from the cover plate 2) are respectively pressed at both ends of the connecting part 5, and the part of the inner end of the buffer cylinder 41 beyond the limiting cylinder 32 is deformed. In this process, the limiting cylinder 32 serves to limit the maximum deformation of the buffer cylinder 41. The recess 411 extending in the circumferential direction is formed on the outer wall of the part of the buffer cylinder 41 between the cover plate 2 and the side wall 1.

[0045] In some example embodiments, with reference to Figures 4-6 The outer side of the second flange 42 (the side of the second flange 42 exposed to the cover plate 2 in the axial direction) is formed with a recess 421, and the first flange 31 is embedded in the recess 421. In other words, the second flange 42 protrudes from the outer end of the buffer cylinder 41 in the axial direction, and the inner wall surface of the part of the second flange 42 protruding from the outer end of the buffer cylinder 41 is formed with the recess 421, and the first flange 31 is embedded in the recess 421.

[0046] According to the above arrangement, the embedded design is adopted, so that the first flange 31 is embedded in the second flange 42, which on the one hand serves to avoid the edges of the first flange 31 being knocked and protects the first flange 31, and on the other hand serves to be aesthetically pleasing.

[0047] In some example embodiments, with reference to Figures 4-6 The buffer part 4 is made of rubber material.

On the other hand, the buffer portion 4 made of rubber material has good damping effect to buffer the vibration transmitted between the side wall 1 and the cover plate 2.

[0049] In some example embodiments, referring to Figures 4-6 , the buffer portion 4 is formed on the outer side of the limiting portion 3 by vulcanization process.

[0050] By the above setting mode, the buffer portion 4 is integrally formed on the outer side of the limiting portion 3 to limit the relative position between the buffer portion 4 and the limiting portion 3.

[0051] In some example embodiments, referring to Figures 4-6 , the limiting portion 3 is made of rigid material to limit the compression amount of the buffer portion 4 in the axial direction.

[0055] Similarly, for example, the connecting portion 5 is a bolt, the bolt passes through the cover plate 2 and the side wall 1 and cooperates with a nut to extrude the outer side end of the buffer portion 4 and the outer side of the side wall 1 respectively, and the deformed part of the inner side end of the buffer portion 4 beyond the limiting portion 3, so that the inner side end of the buffer portion 4 and the limiting portion 3 abut against the inner side of the side wall 1 at the same time to combine the side wall 1 and the cover plate 2.

[0056] It should be noted that the connecting device of the embodiment of the utility model, the limiting portion 3 can also extend through the side wall 1 towards the inner side of the cover plate 2, the buffer portion 4 is wrapped on the outer side of the limiting portion 3, the two ends of the connecting portion 5 are respectively extruded the outer side end of the limiting portion 3 and the buffer portion 4 and the outer side of the cover plate 2, the inner side end of the buffer portion 4 is deformed beyond the part of the limiting portion 3, so that the inner side end of the limiting portion 3 and the buffer portion 4 is abutted with the inner side of the cover plate 2 at the same time, to combine the side wall 1 and the cover plate 2. Wherein, the setting mode of the limiting cylinder 32 and the first flange 31 included in the limiting portion 3 and the buffer cylinder 41 and the second flange 42 included in the buffer portion 4 can be reversely set with the setting direction in Figures 5-6 , which will not be repeated here.
