Description
Technical field
The utility model relates to knob, particularly a kind of knob that is difficult for product to cause wearing and tearing.
Background technology
Knob is for product, and with handled easily, existing knob comprises knob body, and knob body is and covers shape, is provided with for by the perforation of bolt on the bottom of knob body, is connected after having bolt to pass this perforation with product.The knob of this structure, in use, is easy to skid, and in use, also easily product is caused to very large wearing and tearing, after long-time use, product may can not change because of serious wear the new knob of use, therefore bring certain constant to user.So, the knob in conventional art is need further improve and optimize.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of knob that is difficult for product to cause wearing and tearing, and its connection on product is reliable and stable, drive product while rotation is difficult for product to cause wearing and tearing, and simple and compact for structure.
The utility model solves the technical scheme that its technical matters adopts:
A kind of knob that is difficult for product to cause wearing and tearing, comprise and be the knob body that covers shape, the bottom of described knob body is provided with for by the perforation of bolt, on bottom, contiguous knob body cavity body place one side is formed with projection, described projection extends axially along knob body, and be close to the chamber wall of described knob body, the xsect of projection is the irregularly shaped of closure; Described knob body is provided with the inner fovea part of the nut part for holding bolt at the opposite side of the relative cavity of bottom.
As the improvement of technique scheme, the xsect of described projection is triangle.
As the further improvement of technique scheme, the xsect of described projection is equilateral triangle.
Preferably, described projection is one-body molded on described knob body.
Further, in described knob body outer perimeter wall, be provided with the anti-skidding portion that avoids hand to skid.
Further, described anti-skidding portion is faced the wall and meditated and is circumferentially spaced and forms by planar wall and imploded arcs.
The beneficial effects of the utility model are: the utility model that adopts said structure, be formed with projection by contiguous knob body cavity body place one side on bottom, projection extends axially along knob body, and be close to the chamber wall of described knob body, the xsect of projection is the irregularly shaped of closure, utilize projection to coordinate with product, make installing after knob, when rotation knob, knob drives product to rotate by the projection on it, abandon the mode of utilizing bolt to drive product to rotate in conventional art, protruding is arranged so that product is stressed evenly, product is not easy to wear, and also the convenient product that drives rotates, because of not easy to wear, just do not need to change knob yet, facilitate user, reduce maintenance cost.The simple and reasonable compactness of the utility model, easy for installation, to implement simply, cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross section view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 1 ~ Fig. 2, a kind of knob that is difficult for product to cause wearing and tearing of the present utility model, comprise and be the knob body 1 that covers shape, the bottom 11 of described knob body 1 is provided with for passing through the perforation 12 of bolt, on bottom 11, contiguous knob body 1 cavity place one side is formed with projection 2, described protruding 2 extend axially along knob body 1, and are close to the chamber wall of described knob body 1, and the xsect of projection 2 is the irregularly shaped of closure.
In the present embodiment, preferred described protruding 2 xsect is triangle.
In the present embodiment, more preferably equilateral triangle of described protruding 2 xsect.
In the present embodiment, preferred, described knob body 1 is provided with the inner fovea part 13 of the nut part for holding bolt at the opposite side of bottom 11 relative cavitys, and the bolt that is arranged so that of inner fovea part 13 can not expose, and has increased the outward appearance of whole product, and aesthetic property is better.
In the present embodiment, in preferred described knob body 1 outer perimeter wall, be provided with the anti-skidding portion 14 that avoids hand to skid, so can facilitate hand-motion knob, avoid occurring skidding.
In the present embodiment, preferably described anti-skidding portion 14 is faced the wall and meditated and 16 is circumferentially spaced and forms by planar wall 15 and imploded arcs.
Adopt the utility model of said structure, be formed with projection 2 by contiguous knob body 1 cavity place one side on bottom 11, projection 2 extends axially along knob body 1, and be close to the chamber wall of described knob body 1, the xsect of projection 2 is the irregularly shaped of closure, utilize projection 2 to coordinate with product, make installing after knob, when rotation knob, knob drives product to rotate by the projection 2 on it, abandon the mode of utilizing bolt to drive product to rotate in conventional art, protruding is arranged so that product is stressed evenly, product is not easy to wear, and also the convenient product that drives rotates, because of not easy to wear, just do not need to change knob yet, facilitate user, reduce maintenance cost.The simple and reasonable compactness of the utility model, easy for installation, to implement simply, cost is low.
The above, be preferred embodiments of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
