Description
Technical field
The utility model relates to a kind of locking-positioning structure, is specifically related to a kind of quick locking position structure.
Background technique
The connecting fastening mechanism that tradition is made up of screw, nut, bullet pad and packing ring is when connected piece needs dismounting, a series of part must be unloaded, in unloading process, easily cause the loss of indivedual finding, the finding lost in some application may form significant threat to equipment; And when selecting the small dimension tradition fastening form of mechanical connection, the driver flutes of nut is easily by stubborn evil idea or occur the situation that screw-driver skids in the driver flutes that top is through; Simultaneously conventional threads connects fastening form and also has that screw is more difficult is screwed into tapped hole, the phenomenon of small dimension tapped hole stripped thread.
Model utility content
For above-mentioned deficiency of the prior art, the utility model provides one to prevent finding from dropping, automatically reset quick locking position structure.
In order to reach foregoing invention object, the technical solution adopted in the utility model is:
There is provided a kind of quick locking position structure, it comprises nut, stud, spring, sleeve, connected piece two and connected piece one; Be provided with the second mounting hole in connected piece two, the second mounting hole is the unthreaded hole being provided with step; Be provided with the first mounting hole in connected piece one, the first mounting hole upper end is unthreaded hole section, and lower end is provided with thread section; After connected piece two and connected piece one are fixedly installed togather, stud lower end is arranged in the second mounting hole and the first mounting hole; Be positioned at stud in the part outside connected piece two and be arranged with sleeve and the spring being partly positioned at sleeve; The tail end of stud is installed with nut.
The beneficial effects of the utility model are: because the second mounting hole set in connected piece two is step-like unthreaded hole, make the part of this locking-positioning structure be all limited in connected piece two and between nut, therefore the loss occurring finding is not easy, the threat that the finding reducing loss is formed equipment.
Sleeve energy control spring screw degree, there is axial positioning function; Stud lower end is positioned at the unthreaded hole section of the second mounting hole and the first mounting hole, serves radial location function, and so screw is more difficult is screwed into tapped hole, makes the phenomenon of thread section stripped thread also suppressed simultaneously.
When nut screws, spring is compressed, and when nut unscrews, the elastic force of spring self discharges the reset of help nut, and simultaneously because stud and nut link together, stud is also driven reset.
Nut after the not exclusively through driver flutes arranged, enhance the intensity of driver flutes, and the phenomenon that screw-driver when turning small dimension nut skids can be prevented.

Embodiment
Below embodiment of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of embodiment; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
As shown in Figure 1, this quick locking position structure comprises nut 7, stud 6, spring 4, sleeve 3, connected piece 22 and connected piece 1; Be provided with the second mounting hole in connected piece 22, the second mounting hole is the unthreaded hole being provided with step, and the step of the second mounting hole is arranged on the second mounting hole of connected piece 22 near the side of sleeve 3; The matching gap of the step in the second mounting hole and stud 6 is less, therefore can play radial location effect to the stud 6 being arranged in connected piece 22; Simultaneously due to the stop of the step of the second mounting hole, can also by the position limitation of part between connected piece 22 and nut 7; The step of the second mounting hole and part when can ensure that nut 7 unclamps that cooperatively interacts of nut 7 can not drop, thus reduce the threat of losing finding and forming equipment.
Be provided with the first mounting hole in connected piece 1, the first mounting hole upper end is unthreaded hole section, and lower end is set to thread section.
During design, preferably the first preferred Mohs of mounting hole unthreaded hole section part No. 1 tapering positioning hole; Between Mohs No. 1 tapering positioning hole and stud 6, there is less matching gap, the effect of radial location can be played stud 6; Stud 6 directly enters thread section by Mohs No. 1 tapering positioning hole simultaneously, avoid stud 6 when being screwed into tapped hole, that brings due to the inclination of position misalignment and stud 6 self is more difficultly screwed into and the problem of screw thread stripped thread, further increases working efficiency and the reliability of locking-positioning structure.
After connected piece 22 and connected piece 1 are fixedly installed togather, stud 6 lower end is arranged in the second mounting hole and the first mounting hole; Be positioned at stud 6 and the part outside connected piece 22 be arranged with the spring 4 that sleeve 3 and part are positioned at sleeve 3, sleeve 3 can control spring 4 screw degree, and have the effect of axially locating, sleeve 3 and stud 6 limit the radial position of spring 4 jointly.
Side near connected piece 22 in sleeve 3 is provided with step, and the step of sleeve 3 and the step of connected piece 22 all adopt closely spaced location fit, make link 22 and stud 6 radial location; The step of sleeve 3 also limit the position of spring 4 axis, and when nut 7 screws, spring 4 is compressed under the effect of nut 7 and sleeve 3, and when nut 7 unscrews, the elastic force of spring 4 self discharges and promotes nut 7 and reset; With the laminating of spring 4 end face inside the step of sleeve 3, sleeve 3 is fitted with connected piece 22 all the time, avoids the clamping stagnation of spring 4.
During design, chamfering can also be arranged at sleeve 3 near nut 7 side.
The tail end of stud 6 is installed with nut 7, and nut 7 is fixedly connected with stud 6 with the pin 5 of stud 6 by running through nut 7, when spring 4 promotes also to drive stud 6 to automatically reset when nut 7 resets.
In existing structure using process, the driver flutes on the nut of small dimension is easily destroyed, and just cannot normally use once be damaged, although a common word cutter groove is relatively better, still has screw-driver easily to skid, installs the phenomenon of difficulty.
In order to evade above-mentioned defect, nut 7 is provided with the driver flutes 8 at laterally incomplete through nut 7 top, not exclusively through driver flutes 8 ensure that the intensity of driver flutes 8 self, when selecting small dimension fast locking screw cap 7 driver flutes 8 be also not easy due to structure diminish, weakened and by twist bad, or there is the situation that screw-driver skids in driver flutes 8, thus improve usage range and the utilization efficiency of nut 7.
