[0026] As shown in Figures 1-3 The present application provides a new elevator damper structure, which comprises:

[0027] The upper end of the connecting seat 1 is movably inserted with a rubber elastic frame 7 outside, and the upper end of the rubber elastic frame 7 is fixedly connected with a supporting plate 8. The lower end of the supporting plate 8 is fixedly connected with a limiting shaft 11 in the middle part. The limiting shaft 11 is movably and limitingly inserted into the limiting groove 14 opened in the upper side of the connecting seat 1. The reset spring 15 is arranged between the lower end of the limiting shaft 11 and the limiting groove 14.

[0028] The lower end of the supporting plate 8 is fixedly connected with rubber elastic strips 12 at both sides at equal distances. A plurality of springs 13 are fixedly embedded in the interior of the rubber elastic strips 12. The rubber elastic strips 12 are movably inserted into the insertion slot in the upper part of the connecting seat 1.

[0029] The outer lower part of the connecting seat 1 is movably sleeved with an adjusting limiting frame 2. The lower end of the adjusting limiting frame 2 is fixedly connected with an elastic buffer ring 3. The upper end of the adjusting limiting frame 2 is movably inserted with an adjusting screw 18 through threads in the front side. The upper end of the adjusting limiting frame 2 is movably inserted with a positioning screw 21 in the rear side. The adjusting screw 18 is rotatably inserted into the upper outer front side of the connecting seat 1 through the bearing 19. The positioning screw 21 is fixedly inserted into the upper outer rear side of the connecting seat 1 through threads.

[0030] The lower end of the connecting seat 1 is uniformly fixedly connected with several damping springs 17, and the lower end of the damping spring 17 is fixedly connected to the upper end of the bottom plate 6.

[0031] As shown in Figure 2 : the upper end of the connecting seat 1 is fixedly connected with a connecting frame 4, the lower end of the connecting frame 4 is uniformly fixedly connected with a plurality of limiting sliding rods 5, and the limiting sliding rod 5 is movably inserted into the corresponding stable sliding groove 16 opened on the upper side of the adjusting limiting box 2.

[0032] Specifically, the limiting sliding rod 5 can make the up-down displacement of the adjusting limiting box 2 more stable.

[0033] As shown in Figure 3 : the upper end of the connecting seat 1 is provided with a threaded groove in the middle of the front side, the outer side of the adjusting screw 18 is further sleeved with a first nut 20, and the bearing 19 is rotatably arranged in the middle of the front side of the connecting frame 4.

[0034] Specifically, the rotation of the adjusting screw 18 can drive the up-down displacement of the adjusting limiting box 2, and adjust the position of the adjusting limiting box 2.

[0035] As shown in Figure 3 : the upper end of the connecting seat 1 is provided with a circular hole in the middle of the rear side, the lower part of the positioning screw 21 is movably inserted into the circular hole, and the outer side of the positioning screw 21 is sleeved with a second nut 22.

[0036] Specifically, after the position adjustment of the adjusting limiting box 2 is completed, the second nut 22 is twisted by an external tool to make the lower end of the second nut 22 press the upper end of the adjusting limiting box 2.

[0037] As shown in Figure 1 : the upper end of the support plate 8 is fixedly connected with a connecting frame 9 on the left and right sides, and a connecting hole is opened in the middle of the connecting frame 9.

[0038] Specifically, the connecting frame 9 is used to connect the connecting device on the upper part.

[0041] As shown in Figure 1 : the length and width of the outer side of the adjusting limiting box 2 are less than the length and width of the bottom plate 6.

[0042] Specifically, when the lower end of the adjusting limiting box 2 is displaced downward during the buffering process, the maximum displacement amount will press the upper end of the bottom plate 6.

[0043] Principle of use: when the device is in use, the connecting frame 9 on the left and right sides of the upper end of the supporting plate 8 can be fixedly connected to the position where the elevator needs to be damped by bolts, and by manually turning the first nut 20 on the adjusting screw 18 and the second nut 22 on the positioning screw 21, the first nut 20 and the second nut 22 are moved upwards, and then the adjusting screw 18 is rotated by external tools, so that the adjusting limiting frame 2 can be displaced up and down, and the position of the lower end of the adjusting limiting frame 2 from the upper end of the bottom plate 6 is adjusted, so as to limit the damping amplitude of the damping spring 17 or directly limit the damping of the damping spring 17, thereby increasing the stability of the overall structure damping;

[0044] After the position of the adjusting limiting frame 2 is adjusted, when the elevator needs to be damped, the vibration will first be damped by the rubber elastic frame 7, the rubber elastic strip 12 and the reset spring 15, and then damped by the damping spring 17 again, so as to buffer the external vibration, and the frame structure of the rubber elastic frame 7 and the strip structure of the rubber elastic strip 12 can make the overall structure of the device more stable relative to the multiple damping rod damping structures in the buffering state.

[0045] The above is only a specific embodiment of the present application, which enables those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest range consistent with the principles and novel features of the present application.
