Technical Field

[0001] The utility model relates to the technical field of elevator landing door seals, in particular to an elevator landing door seal with an anti-corrosion effect. Background Technique

[0002] During the opening and closing process of the elevator, the two car doors come into contact and separate, resulting in rigid contact during this process. Over time, the car doors made of iron sheet components will be deformed and damaged due to frequent impacts. Moreover, the rigid contact between the landing doors during this process will generate noisy sounds, which does not meet the usage requirements of users for comfortable rides. Therefore, door seals are installed for the elevator.

[0003] In the existing technology, the door seals are symmetrically installed at the ends of the left elevator door and the right elevator door. When the left and right elevator doors close, the left and right door seals are closely attached to each other, thus achieving the effects of sealing and anti-collision.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 3 , an elevator landing door sealing strip with anti-corrosion effect, including a mounting block 1. One end of the mounting block 1 is connected with a bearing plate 2, and a sealing strip mechanism 3 is arranged on the outer wall of the bearing plate 2; the sealing strip mechanism 3 includes butyl rubber 301, and the butyl rubber 301 is fixed on one side of the outer wall of the bearing plate 2. Natural rubber 302 is arranged on the inner wall of the butyl rubber 301. A limiting hole 303 is opened in the butyl rubber 301. A fitting hole 304 is arranged inside the limiting hole 303. A mounting hole 307 is opened on the inner side of the limiting hole 303 close to the bearing plate 2. A sealing strip 306 is fixed on the side of the limiting hole 303 far from the mounting hole 307. A limiting rubber strip 305 is arranged inside the fitting hole 304. A sealing block 308 is fixed at the position of the outer wall of the limiting rubber strip 305 corresponding to the mounting hole 307. The mounting holes 307 are evenly distributed at equal intervals on the outer wall of the butyl rubber 301. The butyl rubber 301 is adhesively connected with the natural rubber 302. A connecting block 4 is arranged on the outer wall of the limiting rubber strip 305 facing the bearing plate 2, and a through hole 5 is opened in the inner wall of the connecting block 4.

[0028] By adopting the above technical solution, first, in the form of a butyl rubber 301 sleeving a natural rubber 302, in cooperation with the limiting holes 303 and the fitting holes 304, and the limiting rubber strip 305 is fitted, so as to avoid the impact of the elevator door and achieve a sealing effect. Due to the wear resistance and corrosion resistance of the butyl rubber 301, in cooperation with the elasticity of the natural rubber 302, it is avoided that damage and corrosion are caused during mutual friction, and the service life of the door seal strip is improved. The limiting rubber strip 305 is limited through the fitting holes 304, and in cooperation with the limiting holes 303, a compression deformation space is reserved to avoid damage caused by excessive friction. The sealing strip 306 can improve the sealing performance during mutual extrusion. The installation holes 307 are used to penetrate the connecting plate 2 and the bolts of the butyl rubber 301 and cooperate with the sealing block 308 to be closed when the elevator is closed. At the same time, through the cooperation of the connecting block 4, the through holes 5 and the bolts, the butyl rubber 301 and the limiting rubber strip 305 can be disassembled and assembled.

[0029] Specifically, as Figure 1 、 Figure 4 and Figure 5 shown, a stress groove 6 is opened at the top of the butyl rubber 301, and a reset mechanism 7 is arranged inside the stress groove 6. The reset mechanism 7 includes a connecting rod 701, the connecting rod 701 is fixed inside the stress groove 6, one end of the connecting rod 701 penetrates into a sleeve 702, the reset mechanism 7 further includes a micro spring 703, the micro spring 703 is embedded at one end of the connecting rod 701 penetrating into the sleeve 702, and an air outlet hole 704 is opened on one side of the outer wall of the sleeve 702. The sleeve 702 and the connecting rod 701 form an elastic structure through the micro spring 703, and the connecting rods 701 are evenly distributed at equal intervals inside the stress groove 6.

[0030] By adopting the above technical solution, the butyl rubber 301 reserves a compression deformation space through the arranged stress groove 6, avoiding the wear and corrosion of the outer wall when being over-pressurized. At the same time, the stress groove 6 is internally provided with a telescopic rod composed of the connecting rod 701 and the sleeve 702. In cooperation with the air outlet hole 704, when the connecting rod 701 slides along the sleeve 702 to form a piston form, it can improve the deformation stability when being pressurized. With the elastic push of the micro spring 703, it can quickly recover in the non-pressurized state.

[0031] Working principle: The installation block 1 is bonded or installed in the corresponding slot of the elevator door. The butyl rubber 301 can be conveniently and quickly disassembled and assembled through the bearing plate 2 and bolts. The inside of the butyl rubber 301 is natural rubber 302 to improve elasticity. The provided limiting holes 303 are used to engage the limiting rubber strip 305 of another elevator door to achieve an anti-collision and sealing effect. The fitting holes 304 provided inside the limiting holes 303 can be fitted with the limiting rubber strip 305, and while cooperating with the sealing strip 306 to reserve a certain compression space, the sealing performance is improved, avoiding excessive compression force. The material of the limiting rubber strip 305 is the same as that of the butyl rubber 301. The inside of the installation hole 307 is used to place the bolts for fixing the butyl rubber 301 and the bearing plate 2, and is blocked by the sealing block 308 fixed by the limiting rubber strip 305 to achieve sealing performance when the elevator is closed. The bearing plate 2 of another elevator door is detachable through the through hole 5 reserved by the fixed connecting block 4 with bolts and the limiting rubber strip 305, and the butyl rubber 301 and the limiting rubber strip 305 can be replaced. The stress groove 6 reserves a deformation space for the compression of the butyl rubber 301, and is supported by the telescopic rod composed of the internal connecting rod 701 and the sleeve 702 at the same time. At the same time, it forms a piston form through the air outlet 704 to improve the stability of stress deformation, and the connecting rod 701 is pushed by the elasticity of the micro spring 703 to enable the stress groove 6 to recover after the elevator door is opened.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
