Abstract
A screw bolt locking mechanism comprises a first pipe, a second pipe, a threaded shaft, a threaded sleeve, an expansion ring, a spring and a separation blade, wherein, the diameter of the first pipe is smaller than that of the second pipe; the threaded shaft comprises a shaft lever, a threaded shaft body and a shaft end; and the first pipe is fixedly connected on the shaft lever of the threaded shaft, openings are formed at two ends of the threaded sleeve which is fixed in a cavity of the second pipe and is in sleeve joint with the threaded shaft body, the expansion ring jackets the shaft end of the threaded shaft and is matched with the opening at one end of the threaded sleeve, the separation blade is fixed on the shaft end of the threaded shaft and is in sleeve joint therewith, and the spring is located between the separation blade and the expansion ring and jackets the shaft end of the threaded shaft. The mechanism can not only firmly lock the pipes, but also dispense with back locking.
Description
Technical field
The utility model relates to a kind of bindiny mechanism, relates in particular to a kind of bolt locking mechanism.
Background technique
Part in the existing pipe thread locking mechanism because size has deviation slightly, will occur locking.After when the pipe thread locking mechanism uses one section, thread bush will produce distortion, and its outer surface can not effectively be contacted with bassoon, skidding will occur like this, makes that the pipe lock is not tight.
Summary of the invention
The purpose of this utility model provides a kind of bolt locking mechanism, and pipe is locked firmly and the bolt locking mechanism of not locking.
The technical solution of the utility model is:
A kind of bolt locking mechanism comprises first pipe, second pipe, thread spindle, thread bush, expansion loop, spring and catch.The diameter of first pipe is less than second pipe diameter, thread spindle comprises axostylus axostyle, thread spindle body and axle head, described first pipe is fixedly connected on the described thread spindle axostylus axostyle, described thread bush both ends open, be fixed in the second pipe cavity, and be socketed on the described thread spindle body, described expansion loop is enclosed within on the described thread spindle axle head, and match with described thread bush one end opening, described catch socket is fixed on the described thread spindle axle head, described spring is sheathed on described thread spindle axle head between described catch and expansion loop.
More firm for the connection that makes pipe, offer draw-in groove at the sidewall of second pipe, the sleeve pipe of a both ends open is placed in the jointing of first pipe and second pipe, and inside pipe casing has protruding stupefied draw-in groove with second pipe to match.
The beneficial effects of the utility model are:
Bolt locking mechanism described in the utility model comprises first pipe, second pipe, thread spindle, thread bush, expansion loop, spring and catch.Be used expansion loop, spring and catch at the thread spindle axle head, pipe locking firmly and is not locked.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model bolt locking mechanism locking state;
Fig. 2 is the cross-sectional view that the utility model bolt locking mechanism unscrews state.
Embodiment
Further specify structure characteristic of the present utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model bolt locking mechanism comprises first pipe 1, second pipe 2, thread spindle 3, thread bush 4, expansion loop 5, spring 6 and catch 7.The diameter of first pipe 1 is less than second pipe, 2 diameters, and thread spindle 3 comprises axostylus axostyle 31, thread spindle body 32 and axle head 33.First pipe 1 is fixedly connected on the described thread spindle axostylus axostyle 31, and described thread bush 4 both ends opens 41,42 are fixed in second pipe, 2 cavitys, and are socketed on the described thread spindle body 32.
Expansion loop 5 is enclosed within on the thread spindle axle head 33, and matches with thread bush one end opening 42.Catch 7 is fixed on the thread spindle axle head 33.Spring 6 is sheathed on described thread spindle axle head 33 between catch 7 and expansion loop 5.
