Abstract

The utility model provides an adjustable rotary fixing bolt which is good in fixing effect. The adjusting rotary fixing bolt comprises a fixing head, a screw rod and a nut, and is characterized by further comprising a sleeve, a fixing bolt, fixing holes and a movable groove, wherein the movable groove is formed in the front side of the sleeve, an inner thread is arranged on the rear side of the sleeve, one fixing hole is formed in the front side of the sleeve, one fixing hole is formed in the fixing head, and the fixing head is of an isosceles trapezoid shape. According to the adjustable rotary fixing bolt, a traditional rectangular positioning head is changed into a trapezoid or triangular positioning head, when needing to be fixed on a wall which has small seams or an uneven inside, the adjustable rotary fixing bolt can be fixed by adjusting the position of the positioning head through the screw rod so that the bolt can be well fixed to the wall and the situation that the bolt can not be fixed due to the small seams can not occur, the use range of the adjustable fixing bolt is widened, and stability of the adjustable fixing bolt is improved.

Description

A kind of adjustable rotary fixing screw bolt
Technical field
The utility model relates to a kind of fixed component, relates in particular to a kind of fixing bolt.
Background technique
Bolt, mechanical parts, the cylindrical threaded fastening piece of adapted nut.Bolt mainly plays fixation, the instrument that is absolutely necessary in the middle of daily life and industrial production manufacture, and bolt is also referred to as the rice of industry, and the utilization of visible bolt is extensively.According to different fixed demand bolts, be divided into a variety of, rotary fixing screw bolt is for the fixing instrument of article in gap or hollow wall, rotary fixing screw bolt gland is now rectangle and both sides are different in size causes, during use, need only gland is put into boring, because gland both sides are different in size, can rotate to be then bolted on wall, but this rotary fixing screw bolt needs in wall, there is larger space while using, if space or gap are less, rotary fixing screw bolt can not be fixed, even if sometimes use by force, fixed effect is poor, the easy landing of article.
Summary of the invention
According to above technical problem, the utility model provides a kind of adjustable rotary fixing screw bolt of good fixing effect, comprise gland, screw rod, nut, characterized by further comprising sleeve pipe, fixed bolt, fixed hole, moving trough, described sleeve pipe front side is provided with moving trough, rear side is provided with internal thread, described sleeve pipe front side is provided with fixed hole, described gland is provided with fixed hole, described gland is isosceles trapezoid, described fixed bolt is fixed together both through the fixed hole in sleeve pipe and gland, described gland and moving trough are parallel structure, described sleeve is fixed together by internal thread and the screw rod of rear side, on described screw rod, be fixed with nut.
A kind of adjustable rotary fixing screw bolt, comprise gland, screw rod, nut, characterized by further comprising sleeve pipe, fixed bolt, fixed hole, moving trough, described sleeve pipe front side is provided with moving trough, rear side is provided with internal thread, described sleeve pipe front side is provided with fixed hole, described gland is provided with fixed hole, described gland is that two triangles form, described fixed bolt is fixed together both through the fixed hole in sleeve pipe and two triangle glands, described gland and moving trough are parallel structure, described sleeve is fixed together by internal thread and the screw rod of rear side, on described screw rod, be fixed with nut.
Described spiro rod rear end is provided with cross recess.
The beneficial effects of the utility model are: the utility model changes traditional rectangle positioning head into trapezoidal or triangle positioning head, when needs are fixed on the little or inner rough metope in gap by the utility model, the utility model can regulate the position of positioning head to be fixed by screw rod, can well be fixed on metope, there will not be can not be fixing because gap is little situation occur, expand the using scope of adjustable fixing bolt, also improved the stability of adjustable fixing bolt.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model bolt rear side schematic diagram;
Fig. 4 is the utility model sleeve structure schematic diagram.
As shown in Figure 1, Figure 2, Fig. 3, icon 4, gland-1, screw rod-2, nut-3, moving trough-4, sleeve pipe-5, fixed bolt-6, fixed hole-7;
Embodiment
Shown in Fig. 1, Fig. 2, Fig. 3, icon 4, the utility model is further described:
Embodiment 1
During installation, first in sleeve pipe 5 front sides, offer moving trough 4 and fixed hole 7, rear side arranges internal thread, then in gland 1, offer fixed hole, again fixed bolt 6 is fixed together both through the fixed hole 7 in sleeve pipe 5 and gland 1, by sleeve pipe 5, internal thread and the screw rod 2 by rear side is fixed together again, finally set screw nut 3 on screw rod 2.
Embodiment 2
During use, first on the wall of fixing article, hole, then mounted the utility model is started the utility model to put into the boring of accomplishing fluently from gland 1, then by rotary screw 2, regulate the position in the space in gland 1 and wall, the utility model is fixed on wall, finally the fixing article of needs are put on screw rod 2, nut 3 is screwed into screw rod 2, article are fixed on wall.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
