Abstract
The utility model discloses a loosening-and-separation-preventing bolt. The loosening-and-separation-preventing bolt comprises a threaded rod and a nut, wherein at least one clamping groove is formed in the threaded rod in the axial direction of the threaded rod, and at least one through hole is formed in the nut. The loosening-and-separation-preventing bolt further comprises a clamping head, wherein the inner end of the clamping head penetrates through the through hole, and then is used in cooperation with the clamping groove. The loosening-and-separation-preventing bolt has the advantages of being simple in structure, easy to manufacture and good in loosening-and-separation-preventing effect.
Description
Technical field
The present invention relates to link technical field, especially relate to a kind of locking bolt that moves back.
Background technique
Bolt comprises screw rod and nut, is the most important and common link.For prevent in bolt using process nut voluntarily pine move back, there is the various informative locking bolt that moves back.Yet, most lockingly move back bolt or the locking effect of moving back is poor, or preparation difficulty is larger, or uses inconvenience.
Summary of the invention
The object of this invention is to provide a kind of locking bolt that moves back, it has simple in structure, is easy to preparation and the locking good feature of effect of moving back.
The technical solution adopted in the present invention is: the locking bolt that moves back, comprise screw rod and nut, on described screw rod along at least 1 clamp bar slot that is axially arranged with of this screw rod, described nut is provided with at least 1 through hole, simultaneously, this locking bolt that moves back includes dop, and the inner of this dop is through matching with this draw-in groove after this through hole.
Described dop is positioned at the end of a clamp, and this clamp is " U " font or " V " font.
Described clamp is spring steel material preparation.
Described draw-in groove is along the shaft axis of this screw rod symmetrical even number bar between two, and described through hole be along the shaft axis of this nut even number of symmetry between two.
The outer cover of described nut has an elastic sleeve, and the inwall of this elastic sleeve contacts with the outer end of this dop.
The advantage that the present invention has is: simple in structure, be easy to preparation, and the locking effect of moving back is better.Of the present inventionly lockingly move back bolt in use, only need dop to be stuck in this draw-in groove, can avoid this nut with respect to this screw rod rotation, thereby avoid preferably the pine voluntarily of this nut to move back.Meanwhile, so locking bolt that moves back is for common bolt, and structural change is less, thereby simple in structure, is easy to preparation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that clamp locking of employing " U " font of embodiments of the invention moves back bolt at the plan view (broken section) of the state of use;
Fig. 2 is that A-A of Fig. 1 is to view;
Fig. 3 is the plan view of the clamp that is " V " font that adopts of the present invention;
Fig. 4 is that sectional view is looked on the locking left side of moving back bolt that employing shallow bore hole of the present invention and clamp coordinate;
Fig. 5 is that sectional view is looked on the locking left side of moving back bolt that employing elastic sleeve of the present invention and dop coordinate.
In figure: 10, screw rod, 11, draw-in groove; 20, nut, 21, through hole, 22, shallow bore hole; 30, clamp, 31, dop; 40, elastic sleeve.
Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: the locking bolt that moves back, comprises screw rod 10 and nut 20.Further say, on this screw rod 10 along at least 1 clamp bar slot 11 that is axially arranged with of this screw rod 10.That is, the axis parallel of this draw-in groove 11 and this screw rod 10.This nut 20 is provided with at least 1 through hole 21.Meanwhile, this locking bolt that moves back includes dop 31, and this through hole 21 is passed afterwards in the inner of this dop 31 and this draw-in groove 11 matches.That is, in use, as long as the inner of this dop 31 withstands in this draw-in groove 11, this nut 20 cannot rotate with respect to this screw rod 10, thereby has avoided the pine voluntarily of this nut 20 to move back.Certainly, when this draw-in groove 11 is many, this dop 31 is stuck in that any one draw-in groove 11 is interior all can play locking effect of moving back.And, when this draw-in groove 11 is many, be beneficial to this nut 20 of fine setting.
As a kind of optimization, this dop 31 is positioned at the end of a clamp 30, and this clamp 30 is " U " font or " V " font, and this clamp 30 is spring steel material preparation.Certainly, should be in conjunction with suitable heat treatment step.Such as, after bending Spring Steel Wire, form the clamp 30 of " U " font or " V " font, and continue to bend inwards and can form 2 dops 31 in the two ends of this clamp 30.Obviously, such clamp 30 is easy to preparation, and easy to use.Further, this draw-in groove 11 is along the shaft axis of this screw rod 10 symmetrical even number bar between two, and this through hole 21 be along the shaft axis of this nut 20 even number of symmetry between two.Such as, as shown in Figure 2, this draw-in groove 11 is that 6, this through hole 21 are 6, and meanwhile, this draw-in groove 11 is symmetrical between two, and this through hole 21 is symmetrical between two.Like this, be convenient to the use of the clamp 30 of " U " font or " V " font, and make the stressed comparatively even of this dop 31, be convenient to play the better locking effect of moving back.Certainly, as shown in Figure 4, on this nut 20, also can be provided with the not penetrating shallow bore hole 22 to these nut 20 inside.Now, this clamp 30 one end be stuck in a through hole 21 in order to playing locking effect of moving back, the other end is stuck in this shallow bore hole 22.Like this, make this locking preparation of moving back bolt comparatively simple.
As another kind optimization, as shown in Figure 5, the outer cover of this nut 20 has an elastic sleeve 40, and the inwall of this elastic sleeve 40 contacts with the outer end of this dop 31.Such as, this elastic sleeve 40 is a rubber ring.Like this, adopt more simple mode to make this dop 31 there is the trend of this draw-in groove 11 of inside clamping.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
