The utility model is realized by the following technical scheme: a dustproof cover for an elevator guide wheel comprises a guide wheel main body and a dustproof cover, wherein the dustproof cover covers the surface of the guide wheel main body, and the guide wheel main body comprises an outer protective layer, a base body layer and an inner ring spring;
the outer protective layer is wrapped and arranged outside the substrate layer, and more than one circle of sealing grooves are formed in the outer protective layer;
the inner ring spring is arranged in the hole of the outer protective layer and used for fastening and sealing.
As a preferable technical scheme, the outer protective layer is made of wear-resistant rubber.
Preferably, the substrate layer is made of a metal material.
Preferably, the inner ring spring is used for fastening the seal with the shaft.
According to a preferable technical scheme, the outer protection layer is connected with the base layer through a first structure, and the inner ring spring is connected with the protection layer through a second assembly structure for assembly.
As a preferred technical scheme, the first assembly structure and the second assembly structure both adopt an injection molding process, or the first structure adopts a vulcanization process, and the second assembly structure adopts an assembly process.
The utility model has the beneficial effects that: the utility model improves the defects that the elevator guide wheel bearing is exposed, is easy to generate static electricity to adsorb dust and is easy to be corroded by water.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is an overall schematic view of the present invention;
fig. 2 is a side cross-sectional view of the present invention.
Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
In the description of the present invention, it is to be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.
Further, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
The use of terms such as "upper," "above," "lower," "below," and the like in describing relative spatial positions herein is for the purpose of facilitating description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features.
