Description

Lock screw soon

Technical field

This utility model relates to hardware products technical field, locks screw soon particularly to one.

Background technology

Screw is as a kind of securing member, for being fixed object.Existing screw compares expense when tightening Time laborious, inefficiency, and fixed effect is the most undesirable, easily produces and loosens, poor reliability.

Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of fixed effect preferably and ratio More time saving and energy saving locks screw soon.

For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is by the following technical programs Realize: one locks screw soon, and including swing handle and screw, described screw has head of screw, stud and is positioned at Tapered portion between head of screw and stud, this head of screw is provided with horizontal through hole, and described swing handle is laterally arranged in In the horizontal through hole of the head of screw of this screw, swing handle can move along the horizontal through hole of head of screw, described swing handle Two ends be separately installed with a backstop head, the stud of described screw is provided with an adapter sleeve, described stud Lower end has a pointed section, and the diameter of the tapered portion of described screw is progressively reduced to lower end by upper end, described spiral shell The lower section of ailhead is provided with pad.

Further, the bottom surface of described pad is provided with pawl.

Further, the both ends of described swing handle are equipped with screw thread, and described backstop head is installed on rotation by screw thread The end of handle.

The beneficial effects of the utility model are: before utilizing swing handle to twist this screw, can first move swing handle, from And increase the arm of force of swing handle the turn of the screw so that during the turn of the screw, the most time saving and energy saving, work efficiency is high, it is achieved Quick fastening screw.It addition, when the upper fixing object of certain bare bones (such as plate body), object only need to be opened If a common installing hole, the adapter sleeve on screw coordinates with the common installing hole of the object fixed, and is twisting During this screw, the pointed section of the stud lower end of screw can realize the self tapping effect of this screw, when the stud of screw After being screwed into bare bones under the effect of screw thread and pointed section, continue to twist screw, the then company of screw-in of taper portion of screw In female connector, due to the effect of tapering so that adapter sleeve expands, thus adapter sleeve swelling is in the object fixed On, it is achieved object Fast Installation on bare bones is fixed.This utility model by the fixation of stud and The expansion of adapter sleeve, it is achieved fixing of object, fixed effect is preferable, and object is not likely to produce loosening, can Good by property.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that this utility model Advantage and feature can be easier to be readily appreciated by one skilled in the art, thus to protection domain of the present utility model Make apparent clear and definite defining.

As it is shown in figure 1, one locks screw soon, including swing handle 1 and screw 2, described screw 2 has head of screw 21, stud 22 and the tapered portion between head of screw 21 and stud 22 23, this head of screw 21 sets Horizontal through hole, described swing handle 1 is had laterally to be arranged in the horizontal through hole of head of screw 21 of this screw 2, swing handle 1 can move along the horizontal through hole of head of screw 2, and the two ends of described swing handle 1 are separately installed with a backstop 3, Being set with an adapter sleeve 4 on the stud 22 of described screw 2, the lower end of described stud 22 has a pointed section 221, the diameter of the tapered portion 23 of described screw 2 is progressively reduced to lower end by upper end, and this tapered portion 23 is The diameter of lower end is equal to the internal diameter of adapter sleeve 4, and the lower section of described head of screw 21 is provided with pad 5.

Furtherly, the bottom surface of pad 5 is provided with pawl 51.Pawl 51 on pad 5 can tightly be stung It is combined in the surface of fixed object, increases resistance, thus this screw will not loosen, more ensure that this The installation reliability of screw.

Furtherly, the both ends of swing handle 1 are equipped with screw thread, and backstop 3 is installed on swing handle by screw thread End.Backstop 3 can arbitrarily dismount, and facilitates the installation and removal of swing handle 1.

When fixing object on plate body, operator can move this swing handle 1 so that certain one end of swing handle 1 Stop block 3 recline with head of screw 21, then, operator rotate swing handle 1, by the stud 22 of screw 2 It is screwed on plate body by self tapping effect, the object fixed is sleeved on the adapter sleeve 4 on screw 2, continues Continuous rotation swing handle 1 so that the tapered portion 23 of screw 2 progressively screws in adapter sleeve 4, due to the cone of screw 2 The effect of the tapering in shape portion 23 so that adapter sleeve 4 expands, the final swelling of adapter sleeve 4 is in the object fixed In, thus realize object fixing on plate body.

This utility model can increase the arm of force of swing handle 1 the turn of the screw by mobile swing handle 1 so that during the turn of the screw, The most time saving and energy saving, work efficiency is high, it is achieved Quick fastening screw.On certain bare bones (such as plate body) During fixing object, object only need to offer a common installing hole, the adapter sleeve 4 on screw 2 with fixed Object common installing hole coordinate, twist this screw time, the pointed section 221 of stud 22 lower end of screw 2 Can realize the self tapping effect of this screw, and the effect of tapering of the tapered portion 23 due to screw 2, can the company of making Female connector 4 expands, thus adapter sleeve 4 swelling is on the object fixed, it is achieved fast on bare bones of object Speed is installed fixing, and work efficiency is higher.This utility model is by the fixation of stud 22 and adapter sleeve 4 Expansion, it is achieved fixing of object, fixed effect is preferable, and object is not likely to produce loosening, good reliability.

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, Every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion, or directly Connect or be indirectly used in other relevant technical fields, be the most in like manner included in patent protection model of the present utility model In enclosing.
