Abstract
The utility model provides an improved structure of a tap bolt, comprising a screw rod, wherein the screw rod is provided with at least one row of scrap discharging groove. The scrap discharging groove is an arc-shaped groove; a screwing-in end of the scrap discharging groove is provided with a circular-arc angle; and a screwing-out end of the scrap discharging groove is provided with an acute angle. The improved structure of the tap bolt can effectively improve the scrap containing capability and the scrap guiding capability of the scrap discharging groove so that the smooth operation of the locking work is ensured.
Description
Technical field
The utility model relates to a kind of tap bolt and improves structure, relates in particular to a kind of appearance bits of groove and tap bolt improvement structure of dust lead ability of improving.
Background technique
Generally be provided with at least one groove on the screw rod of existing tap bolt; The bits material that in the locking process, produces with ccontaining tap bolt; And will consider material to be worth doing with the screw lock of tap bolt and derive, and then can avoid considering to be worth doing the residual of material and pile up, guarantee carrying out smoothly of tap bolt locking operation.
Yet the groove of this tap bolt is generally a V font groove, and the space of its ccontaining bits material is comparatively limited; Simultaneously, the precession end of this V-arrangement groove is the obtuse angle with screwing out end, and the bits material that is prone to cause tap bolt in the locking process, to produce is difficult to successfully get into groove by the precession end, and this precession end also is difficult to effectively the bits material of remnants discharged from groove.Thus, be prone to influence carrying out smoothly of tap bolt locking operation.
The model utility content
In view of this, be necessary to provide a kind of tap bolt that can address the above problem to improve structure.
A kind of tap bolt improves structure, includes a screw rod, and this screw rod is provided with at least one groove.This groove is an arc groove, and the precession end of this groove is an arc round angle, and the back-out end of this groove is an acute angle.
Compared with prior art, the groove that the tap bolt that the utility model provides improves in the structure is an arc groove, utilizes this groove can improve the volume space of bits material effectively.Simultaneously, the precession end of this groove is an arc round angle, and the back-out end of this groove is an acute angle, thus, helps the bits material to get in the groove smoothly, and can effectively the bits material of remnants be discharged from groove.Therefore, can improve the appearance bits and the dust lead ability of groove, guarantee that tap bolt improves carrying out smoothly of structure locking operation.
Above-mentioned explanation only is the general introduction of the utility model technological scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, and for let the above-mentioned of the utility model with other purpose, feature and advantage can be more obviously understandable, below special act embodiment; And conjunction with figs., specify as follows.
Description of drawings
Fig. 1 is the schematic perspective view that the tap bolt that provides of the utility model improves structure.
Fig. 2 is the front elevation that tap bolt shown in Figure 1 improves structure.
Fig. 3 is that tap bolt shown in Figure 2 improves the sectional view of structure along the III-III direction.
Fig. 4 is that tap bolt shown in Figure 3 improves the sectional view of structure along the IV-IV direction.
Embodiment
Be further elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be appreciated that specific embodiment described herein as just embodiment, and be not used in the protection domain that limits the utility model.
Please consult Fig. 1 and Fig. 2 in the lump, the utility model one embodiment provides a kind of tap bolt 20, and it comprises a screw rod 21, and this screw rod 21 is provided with at least one groove 22.Please consult Fig. 3 and Fig. 4 simultaneously, this groove 22 is an arc groove, and the precession end 221 of this groove 22 is an arc round angle, and the back-out end 222 of this groove 22 is an acute angle.
Because this groove 22 is an arc groove, so it can improve the volume space of bits material.Simultaneously, because the precession end 221 of this groove 22 is an arc round angle, therefore helps the bits material to get in this groove 22 smoothly, and, therefore help the bits material of remnants is discharged from this groove 22 because the back-out end 222 of this groove 22 is an acute angle.
Can know that the tap bolt that the utility model provides improves appearance bits and the dust lead ability that structure can improve groove 22 effectively, guarantees to lock carrying out smoothly of operation.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Interior any modification of doing of all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included in the protection domain of the utility model.
Claims (1)
