Description
Technical field
The utility model relates to component connection areas more particularly to a kind of floating not to deviate from bolt structure.
Background technique
Do not deviate from screw to be usually used on the components that cover board etc. is often dismantled, its advantages are that screw will not be with quilt after dismantling
Connector separation, can prevent screw from losing.In certain engineer application occasions, for example, it is some it is larger-size, easily deform
Weldment, medium-and-large-sized machined piece etc., hole position error is difficult to reach higher required precision.In this case, the light of screw
Rod segment is easily interfered with the thread of connected piece screw through hole, and screw is caused to misplace.If assembling by force, screw will bear huge
Radially bending load, cause screw to be damaged by " not disconnected " or screw thread.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of float is provided and does not deviate from screw knot
Structure, which in turn ensures that screw rod has enough free gaps while realizing that screw does not deviate from function, to improve spiral shell
The fabrication tolerance of nail.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and a kind of float does not deviate from bolt structure, including
There are connector, connected piece, does not deviate from screw, stop reed, captive nut, plays flat shim；The connector and connected piece
On be provided with corresponding screw hole, wherein the screw hole inner wall of connector is helicitic texture, and the screw hole inner wall of connected piece is
Unthreaded hole structure, and the screw hole of connected piece is provided with the annular groove that two loop diameters increase step by step to connector on one side, wherein diameter
A bigger ring slot is back stop slot；Described not deviate from screw be that national standard does not deviate from bolt structure, this does not deviate from screw across quilt
Connector screw hole is simultaneously threadedly attached on connector；It is described do not deviate from be set with thrust spring at the external back stop slot of screw
Piece, the thrust reed are spill reed structure, and both ends are held out against respectively on connector end face and back stop slot；It is described not deviate from screw
Captive nut is set with outside the annular groove adjacent to back stop slot, there are gaps between the captive nut and annular groove；It is described not deviate from
Bullet flat shim is provided between screw and connected piece end face.
Preferably, the connected piece screw hole and not deviating between screw that there are gaps.
The beneficial effects of the utility model are: the structure in turn ensures that screw rod has while realizing that screw does not deviate from function
Enough free gaps, to improve the fabrication tolerance of screw.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is to float not deviating from bolt structure schematic diagram.
Wherein: 1 is connector, and 2 be connected piece, and 3 is do not deviate from screw, and movable contact spring until 4,5 be captive nut, and 6 are
Play flat shim.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, it is a kind of floating do not deviate from bolt structure, include connector 1, connected piece 2, do not deviate from screw 3,
Stop reed 4, plays flat shim 6 at captive nut 5；It is provided with corresponding screw hole on the connector 1 and connected piece 2, wherein
The screw hole inner wall of connector 1 is helicitic texture, and the screw hole inner wall of connected piece 2 is unthreaded hole structure, and the spiral shell of connected piece 2
Nail hole is provided with the annular groove that two loop diameters increase step by step to connector on one side, and wherein the bigger ring slot of diameter is back stop slot；
Described not deviate from screw 3 be that national standard does not deviate from bolt structure, this does not deviate from screw 3 across 2 screw hole of connected piece and passing through spiral shell
Line is connected on connector 1；It is described do not deviate from be set with thrust reed 4 at the external back stop slot of screw 3, the thrust reed 4 be it is recessed
Shape reed structure, both ends are held out against respectively on 1 end face of connector and back stop slot；It is described not deviate from screw 3 adjacent to back stop slot
Annular groove outside be set with captive nut 5, there are gaps between the captive nut 5 and annular groove；It is described not deviate from screw 3 and be connected
It is provided between 2 end face of part and plays flat shim 6.
When it is implemented, 2 screw hole of connected piece and not deviating between screw 3 that there are gaps.
When practical operation, the screw through hole on connected piece 2 has been changed to unthreaded hole by threaded hole, is meeting national standard to screw
Under the premise of through hole diametric requirements, the diameter of through-hole can be designed big as far as possible, not deviate from 3 polished rod position of screw for increasing
Gap between through-hole side wall.
Claims (2)
