Description

Technical Field

[0001] The utility model relates to the technical field of elevator shock absorption, in particular to an elevator car top shock absorber. Background Art

[0002] In order to make the elevator more comfortable during operation, a shock absorber is designed on the top of the elevator car. The shock absorber is mainly composed of sheet metal and elastic rubber. Figure 1 As shown, the rubber mounting structure of the conventional elevator car top shock absorber is to fix the shock absorbing rubber, the shaft ring, the gasket, etc. on the shock absorbing arm with bolts, wherein the hole opened in the shock absorbing arm is a threaded hole.

[0021] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like are used to indicate positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of this utility model and to simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used solely for descriptive purposes and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] Figure 2 This is a schematic structural diagram of the elevator car top shock absorber in the utility model; Figure 3 This is a schematic diagram of the explosion of the elevator car top shock absorber in the utility model; Figure 4 This is a schematic diagram of the structure of the shock-absorbing rubber in the utility model; Figure 5 yes Figure 4 Section view in the AA direction. Figures 2 to 5 As shown, a preferred embodiment is shown, in which the elevator car top shock absorber includes a shock absorbing arm 1 and a shock absorbing rubber 2. A through hole 3 is provided on the shock absorbing arm 1, and a connecting arm 4 is provided at one end of the shock absorbing rubber 2. The connecting arm 4 can be inserted into the through hole 3. The surface of the end of the connecting arm 4 away from the shock absorbing rubber 2 is a conical surface 5, and a limited surface 6 is provided on the outer wall of the end of the connecting arm 4 away from the shock absorbing rubber 2. In this embodiment, the connecting arm 4 and the shock absorbing rubber 2 are integrally provided, and the connecting arm 4 extends out of the shock absorbing rubber 2. Through the mutual cooperation between the connecting arm 4 and the through hole 3, the shock absorbing rubber 2 can be quickly installed on the shock absorbing arm 1, and the shock absorbing rubber 2 can also be quickly removed, making installation or removal more convenient. Among them, see Figure 5 As shown, the middle portion of the shock-absorbing rubber 2 is solid, not through-hole, which can achieve a better shock-absorbing effect on the car. A tapered surface 5 is provided at the end of the connecting arm 4 to facilitate the connecting arm 4 to enter the through hole 3, and a limiting surface 6 is provided to facilitate contact with the outer wall of the through hole 3 to achieve a limiting effect and prevent the connecting arm 4 from falling out of the through hole 3.

[0025] When in use, the conical surface 5 at the end of the connecting arm 4 is inserted into the through hole 3, and then the shock-absorbing rubber 2 is pressed and rotated so that the shock-absorbing rubber 2 pushes the connecting arm 4 into the through hole 3 until the conical surface 5 passes through the through hole 3. At this time, the limiting surface 6 will abut against the outer wall of one side of the through hole 3, and the end surface of the shock-absorbing rubber 2 will abut against the outer wall of the other side of the through hole 3, preventing the connecting arm 4 from detaching from the through hole 3.

[0026] Furthermore, as a preferred embodiment, the inner wall of the through hole 3 is smooth, wherein a groove 7 is provided in the middle of the shock-absorbing rubber 2. The provision of the groove 7 facilitates pressing the shock-absorbing rubber 2 during installation, and can reduce the weight of the shock-absorbing rubber 2, saving manufacturing costs.

[0027] Furthermore, as a preferred embodiment, the outer edges of the two end surfaces of the shock-absorbing rubber 2 are arc-shaped surfaces. When the shock-absorbing rubber 2 is rotated, the sharp outer edges of the end surfaces of the shock-absorbing rubber 2 can be prevented from contacting the staff and causing discomfort, thereby improving the comfort of use.

[0028] Furthermore, as a preferred embodiment, the shock absorbing arm 1 has an L-shaped side wall 10, the through hole 3 is provided on the side wall 10, and the shock absorbing arm 1 is also provided with a connecting hole 8. The shock absorbing arm 1 also has a connecting plate 9 integrally connected to the side wall 10, and the connecting plate 9 is provided with a connecting hole 8, into which a bolt can be inserted for connecting to the external elevator car roof.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
