Abstract
The utility model discloses a kind of screw mandrel, the nut comprising screw rod and coordinate with described screw rod, described screw rod is provided with threaded line group, and described threaded line group comprises five threaded line matched; Be provided with the guide groove closed with described threaded line assembly inside described nut, between described guide groove and described threaded line group, be provided with reversing tube.The beneficial effects of the utility model: the utility model has five threaded line, and bearing capacity can improve 25%, stability is good, long service life, can meet work requirements now.
Description
Technical field
The utility model relates to mechanical parts, specifically, relates to a kind of screw mandrel.
Background technique
At present, existing 2525 screw mandrels are 4 threaded line, and along with the development of technology, described 2525 screw mandrels cannot satisfy the demands, and the bearing capacity of 4 line style 2525 screw mandrels is also not enough.
So, develop the screw mandrel that a kind of bearing capacity is high, meet work requirements, just become the problem that Professional visitors needs solution badly.
Model utility content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of screw mandrel, its bearing capacity increases greatly.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of screw mandrel, the nut comprising screw rod and coordinate with described screw rod, described screw rod is provided with threaded line group, and described threaded line group comprises five threaded line matched; Be provided with the guide groove closed with described threaded line assembly inside described nut, between described guide groove and described threaded line group, be provided with reversing tube.
Further, the material of described reversing tube is metal material.
The beneficial effects of the utility model: the utility model has five threaded line, and bearing capacity can improve 25%, stability is good, long service life, can meet work requirements now.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the screw mandrel according to the utility model embodiment;
Fig. 2 is the cross-sectional perspective view of the screw mandrel according to the utility model embodiment;
Fig. 3 is that the screw rod according to the utility model embodiment coordinates figure with reversing tube.
In figure:
1, screw rod; 2, nut; 3, threaded line; 4, guide groove; 5, reversing tube.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope of the utility model protection.
As Figure 1-3, a kind of screw mandrel according to the utility model embodiment, the nut 2 comprising screw rod 1 and coordinate with described screw rod 1, described screw rod 1 is provided with threaded line group, and described threaded line group comprises five threaded line matched 3; Be provided with the guide groove 4 closed with described threaded line assembly inside described nut 2, between described guide groove 4 and described threaded line group, be provided with reversing tube 5.
In one embodiment, the material of described reversing tube 5 is metal material.
Conveniently understand technique scheme of the present utility model, below by way of in concrete usage mode, technique scheme of the present utility model is described in detail.
When specifically using, according to screw mandrel described in the utility model, by comprising the threaded line group of five threaded line 3, work can be made more stable, and bearing capacity effectively improves 25%.
The material of described reversing tube 5 can select iron or copper etc.
In sum, by means of technique scheme of the present utility model, the utility model has five threaded line 3, and bearing capacity can improve 25%, and stability is good, long service life, can meet work requirements now.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
