Description

Loading screw that steadiness can be high

Technical Field

The utility model relates to a screw technical field especially relates to a loading screw that steadiness can be high.

Background

Screws are a common fastener and are widely used in machinery, electrical appliances and buildings. The general material is metal or plastic, is cylindrical, and the surface is carved with the concave and convex ditch and is called the screw thread, and current loading screw often can slowly drop because of there being the gap in the in-process that uses because of the shake of gap between screw and the screw thread in the use, needs the workman to regularly inspect and screw up, has wasted the manpower in a large number, and it is very inconvenient to use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a loading screw with high stability.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a loading screw that steadiness can be high, includes the nut, nut fixed mounting is on the screw top, the bottom fixedly connected with threaded rod of nut, the one end threaded connection that the nut was kept away from to the threaded rod has the thread bush.

Preferably, the threaded rod is close to one end of nut and is served the thread bush and be equipped with the nut, one side fixedly connected with spacing ring that the nut kept away from the nut, the spacing ring is the U type form.

Preferably, the outer wall of the screw cap is provided with strip-shaped raised friction particles.

Preferably, two round holes are formed in the threaded sleeve, and a resistance mechanism is arranged on the threaded sleeve.

Preferably, the resistance mechanism comprises two limiting blocks which are slidably mounted in the corresponding two round holes.

Preferably, two the stopper runs through the thread bush and extends to inside the thread bush, two one side that the stopper is close to the threaded rod respectively is the inclined plane form.

Compared with the prior art, the beneficial effects of the utility model are that:

1. in the utility model, the threaded sleeve is arranged along the threaded hole, and then the screw cap is rotated, the threaded rod can rotate inwards along the thread of the inner wall of the threaded sleeve, and the gap between the inner wall of the threaded sleeve is narrow, so that the threaded sleeve and the threaded hole can be tightly attached, and the phenomenon of falling off caused by the shaking of the gap between the screw and the threaded hole when in use is reduced;

2. in the utility model, the limit block can be pushed out when the threaded rod passes through the limit block which is arranged in the threaded sleeve in a sliding way, so that the limit block is tightly propped against the inner wall of the threaded hole, the stability is improved, and the screw is more stable and relieved when being fixed;

the utility model discloses simple structure, through installing the thread bush in along the screw hole, then rotate the nut again, can let the threaded rod along the screw thread internal rotation of thread bush inner wall, can let closely laminate between thread bush and the screw hole, reduced when using because the shake in gap between screw and the screw hole and produced the phenomenon that drops, the threaded rod can support the stopper out when the stopper of slidable mounting in the thread bush, let stopper and threaded hole inner wall support tightly and increase stability, let more firm when the screw is fixed.

Drawings

Fig. 1 is a schematic structural view of a loading screw with high stability according to the present invention;

fig. 2 is a schematic view of a loading screw with high stability according to the present invention;

fig. 3 is a schematic view of a top view structure of a loading screw with high stability according to the present invention.

In the figure: 1. a nut; 101. a threaded rod; 102. a nut; 103. a limiting ring; 104. a threaded sleeve; 105. and a limiting block.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example one

Referring to fig. 1-3, a loading screw with high stability performance comprises a nut 1, wherein the nut 1 is fixedly installed at the top end of the screw, a threaded rod 101 is fixedly connected to the bottom end of the nut 1, and a threaded sleeve 104 is connected to one end, far away from the nut 1, of the threaded rod 101 in a threaded manner.

Example two

The embodiment is improved on the basis of the first embodiment: threaded rod 101 is close to one of nut 1 and serves the threaded bush and is equipped with nut 102, and one side fixedly connected with spacing ring 103 of nut 1 is kept away from to nut 102, and spacing ring 103 is the U type form, and the outer wall of nut 1 is equipped with the bellied friction grain of bar.

EXAMPLE III

The embodiment is improved on the basis of the first embodiment: be equipped with two round holes on the thread bush 104, be equipped with resistance mechanism on the thread bush 104, resistance mechanism includes two stoppers 105 of slidable mounting in corresponding two round holes, and inside two stoppers 105 run through the thread bush 104 and extend to the thread bush 104, one side that two stoppers 105 are close to the threaded rod 101 respectively is the inclined plane form.

The working principle is as follows: firstly, install threaded sleeve 104 along the screw hole and go, then rotate nut 1 again, can let threaded rod 101 along the screw thread of threaded sleeve 104 inner wall inwards rotate because of the threaded sleeve 104 inner wall gap is narrower, can let closely laminate between threaded sleeve 104 and the screw hole, the phenomenon that has reduced when using because the shake in gap produces between screw and the screw hole produces and drops, and threaded rod 101 can support stopper 105 out through sliding mounting's in threaded sleeve 104 during stopper 105, let stopper 105 support tightly with the screw hole inner wall and increase stability, let the screw more firm relieved when fixed.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
