Abstract
A kind of floating screw is the utility model is related to, it includes screw rod, spring, inner sleeve and outer sleeve；The screw rod includes tack, threaded bar, has groove on the tack；The inner sleeve is cylinder, has outside flange close to one end of spring, and the other end has the circular cylinder shaped portion that internal diameter diminishes, so as to form first shoulder, annular recess on inner sleeve；Remote inner sleeve one end of outer sleeve has inside flange, and the other end has the groove that internal diameter increases, so as to form the second shoulder on outer sleeve；Outer sleeve relative to inner sleeve slidably；Outside flange and inside flange, which cooperate, limits outer sleeve axial movement.Floating screw described in the utility model, have and assemble technique effect simple, easy to use.
Description
Technical field
It the utility model is related to a kind of fastener, and in particular to a kind of floating screw.
Background technology
The component of existing floating screw is more, and it is longer to expend the time in assembling, and part is smaller will also result in assembling
On be not easy and influence volume production efficiency, and then cause quality to be unable to maintain that well.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art and provides a kind of floating screw.
To achieve the above object, the technical solution adopted in the utility model is：Floating screw includes screw rod, spring, inner sleeve
Cylinder and outer sleeve；Screw rod includes tack, threaded bar, has groove on tack；Inner sleeve is cylinder close to one end of spring
With outside flange, the other end has the circular cylinder shaped portion that internal diameter diminishes, so as to form first shoulder, ring-type on inner sleeve
Groove；Remote inner sleeve one end of outer sleeve has inside flange, and the other end has the groove that internal diameter increases, so as in overcoat
The second shoulder is formed on cylinder；Outer sleeve relative to inner sleeve slidably；Outside flange and inside flange, which cooperate, to be limited
Outer sleeve is axially moved.
Further, spring is volute spring.
After said structure, floating screw described in the utility model, assembling is simple, can limit the excessive shifting of outer sleeve
It is dynamic, there is technique effect easy to use.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is the structural representation of floating screw of the present utility model.
Reference represents respectively in figure：Screw rod 1, spring 2, inner sleeve 3, outer sleeve 4, tack 11, threaded bar 12,
Groove 111, outside flange 31, circular cylinder shaped portion 32, first shoulder 33, annular recess 34, inside flange 41, groove 42,
Two shoulders 43.
Embodiment
To make the technical solution of the utility model and advantage clearer, the utility model is implemented below in conjunction with accompanying drawing
Mode is described in further detail.Unless otherwise defined, all technical terms used in the utility model embodiment are respectively provided with
The identical implication being generally understood that with those skilled in the art.
As shown in figure 1, floating screw includes screw rod 1, spring 2, inner sleeve 3 and outer sleeve 4；Screw rod 1 includes tack 11, band
The bar 12 of screw thread, there is groove 111 on tack；Inner sleeve 3 is cylinder, and inner sleeve 3 has outwards convex close to one end of spring
Edge 31, the other end of inner sleeve 3 have the circular cylinder shaped portion 32 that internal diameter diminishes, so as to form first shoulder 33, ring on inner sleeve 3
Shape groove 34；Remote inner sleeve one end of outer sleeve 4 has inside flange 41, and the other end of outer sleeve 4 has what internal diameter increased
Groove 42, so as to form the second shoulder 43 on outer sleeve 4；Outer sleeve 4 relative to inner sleeve 3 slidably；Outside flange 31
Cooperated with inside flange 41 and limit outer sleeve axial movement.
In order that screw rod more easily passes spring, spring is volute spring.
The assembling mode of floating screw of the present utility model is to promote screw rod rotation to wear by the engagement groove of screwdriver
Spring, inner sleeve, outer sleeve are crossed, after being completed, outside flange and the engagement of inside flange are common to limit outer sleeve axial direction
Motion, tack are arranged in groove.
It is described above to be for only for ease of it will be understood by those skilled in the art that the technical solution of the utility model, not to
Limit the utility model.All any modification, equivalent substitution and improvements within the spirit and principles of the utility model, made etc.,
It should be included within the scope of protection of the utility model.
