[0004] The utility model solves the technical problem of how to protect the surface of the elevator button from being worn out after long-term use. In order to improve its shortcomings, the utility model provides a surface not easy to wear elevator button.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical scheme:

[0006] A surface not easy to wear elevator button, comprising a button body and a bottom disc installed in an elevator, a connecting shaft fixed between the button body and the bottom disc connecting the two as a whole, the connecting shaft is embedded with an elastic shaft, the bottom disc is connected with the internal electrical elements of the elevator, the button body is sleeved with a protective sleeve arranged in U-shaped section, the inner end face of the protective sleeve is fixedly connected with an elastic limiting rod, the free end of the elastic limiting rod is provided with a limiting head, and the limiting groove is arranged in the elevator outside the limiting head.

[0007] As a preferred scheme, an observation window is arranged on the outer end surface of the protective sleeve, and a step surface is arranged outside the observation window, and a transparent panel is clamped on the step surface.

[0008] As a preferred scheme, a blind hole for mounting the button body is arranged in the elevator, and a guide sleeve is sleeved on the outer peripheral surface of the button body, and the outer peripheral surface of the guide sleeve is attached to the inner wall of the blind hole.

[0009] As a preferred scheme, the elastic limiting rods are at least evenly arranged in three groups in the circumferential direction of the protective sleeve.

[0010] As a preferred scheme, the protective sleeve and the transparent panel are plastic parts.

[0011] Compared with the prior art, the beneficial effects of the present application are that: due to the cooperation of the protective sleeve and the transparent panel, the button body is prevented from directly contacting the human hand during use, thereby reducing the wear degree of the button surface, and at the same time, the observation of the floor button number by the person is not affected, and the device is suitable for industrial production and has strong practicability. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is a structural schematic view of the present application.

[0013] Figure 2 It is Figure 1 It is a local enlarged view of A in the figure.

[0014] In the figure: 1 button body, 2 base plate, 3 connecting shaft, 4 elastic shaft, 5 protective sleeve, 6 elastic limiting rod, 7 limiting head, 8 limiting clamping groove, 9 observation window, 10 step surface, 11 transparent panel, 12 blind hole, 13 guide sleeve. DETAILED DESCRIPTION

[0015] The technical scheme of the present application will be further described and explained in combination with the drawings and examples.

[0016] As Figures 1-2The utility model discloses a kind of elevator buttons of surface not easy to wear, including the button body 1 installed in elevator and chassis 2, connecting shaft 3 is fixed between button body 1 and chassis 2, connecting shaft 3 is embedded with elastic shaft 4, chassis 2 is connected with internal electrical components of elevator, protective sleeve 5 with the section of U type is sleeved on button body 1, elastic limiting rod 6 is fixed on the inner end surface of protective sleeve 5, the free end of elastic limiting rod 6 is provided with limiting head 7, limiting groove 8 is set in the outside of limiting head 7 in elevator.
