Abstract
The invention discloses a tension expansion locking device which comprises an expansion sleeve and a pull pin, wherein the expansion sleeve comprises a subbase, friction pressing sheets and an elastic sheet; the at least three friction pressing sheets are arranged around the subbase; the two ends of the elastic sheet are fixed on the friction pressing sheets and the subbase respectively; the elastic sheet is used for allowing the friction pressing sheets to return; the pull pin comprises two ejection balls, a pull post, a spring and a pull ring; the two ejection balls are mounted at the top and in the middle of the pull post respectively; the two ends of the spring are connected with the ejection ball mounted in the middle of the pull post and the subbase; the pull ring is arranged at the lower end of the pull post; bulge structures are uniformly arranged on one side, contacted with a wall, of each friction pressing sheet; the upper-half parts of the ejection balls are spherical; and the low-half parts of the ejection balls are tapered to facilitate ejecting the friction pressing sheets. The device has the benefits that the device can hang heavy objects quickly, remove a locking state remotely, and be used for situations where object constraint is required to be removed, but personnel are inconveniently present on site personally.
Description
Technical field
The present invention relates to tension force traction, suspension or bracing wire fixes (as finishing bracing wire, ceiling hanger, crane hangs lifting) and tractive rapid unhooking (as crane placement object rapid unhooking, hanger touches end unloading, tractor deceleration unhook, the weightless parabolic in high-altitude etc.) technical field, specifically, be a kind of pulling force expansion locking device.
Background technique
In daily life, especially in repairs profession, need to be at ceiling permanent or while hanging as light fixture or other decorations temporarily, generally adopt EXPANSION ANCHOR BOLTS to fix, so not only install and waste time and energy, and certain infringement is caused in the hanging positions such as body of wall or roof; Meanwhile, when dismounting, need to unload bolt, just can take off hanger, bring very large inconvenience to construction and daily life.
Summary of the invention
In order to overcome above technical problem, the invention provides a kind of pulling force expansion locking device.
The present invention solves its technical problem and adopts following technological scheme to realize: a kind of pulling force expansion locking device, comprise expansion sleeve and draw pin, described expansion sleeve comprises subbase, friction compressing tablet and shell fragment, around subbase, be provided with at least three friction compressing tablets, described shell fragment two ends are separately fixed on friction compressing tablet and subbase, and the effect of shell fragment is to make to rub compressing tablet return; The described pin that draws comprises heading, stay column, spring and draw ring, and described heading is two, and two headings are installed on respectively stay column top and middle part, and described both ends of the spring is connected and installed in respectively heading and the subbase at stay column middle part, and the effect of spring is to make to draw pin return; Described draw ring is arranged on stay column lower end;
Described subbase middle part is vertically provided with cylindrical tube, and for fixing spring, and keep-spring can offset direction;
Described friction compressing tablet is connected with the cylindrical tube on subbase by bearing pin, and friction compressing tablet can rotate around bearing pin;
In the side that described friction compressing tablet contacts with wall, be evenly provided with protruding structure, with increasing friction force;
Described heading upper half part is sphere, and lower half portion is the conical surface, is beneficial to back down friction compressing tablet.
The beneficial effect that the present invention produces is, the present invention can fast speed hang weight, can also remove at a distance locking state, can be used in need to remove the constraint of object but the personnel body of being not easy to faces on-the-spot situation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, be elaborated:
As shown be structural representation of the present invention
In figure, 1, subbase 2, friction compressing tablet 3, shell fragment 4, heading 5, stay column 6, spring 7, draw ring 8, wall 9, protruding structure 10, cylindrical tube
Embodiment
Specifically describe embodiments of the invention below:
As shown in the figure, a kind of pulling force expansion locking device, comprise expansion sleeve and draw pin, described expansion sleeve comprises subbase 1, friction compressing tablet 2 and shell fragment 3, around subbase 1, be provided with at least three friction compressing tablets 2, described shell fragment 3 two ends are separately fixed on friction compressing tablet 2 and subbase 1, and the effect of shell fragment 3 is to make to rub compressing tablet return; The described pin that draws comprises heading 4, stay column 5, spring 6 and draw ring 7, described heading 4 is two, two headings 4 are installed on respectively stay column 5 tops and middle part, and described spring 6 two ends are connected and installed in respectively heading 4 and the subbase 1 at stay column 5 middle parts, and the effect of spring 6 is to make to draw pin return; Described draw ring 7 is arranged on stay column 5 lower ends;
Described subbase 1 middle part is vertically provided with cylindrical tube 10, and for fixing spring 6, and keep-spring 6 can offset direction;
Described friction compressing tablet 2 is connected with the cylindrical tube 10 on subbase 1 by bearing pin, and friction compressing tablet 2 can rotate around bearing pin;
In the side that described friction compressing tablet 2 contacts with wall, be evenly provided with protruding structure 9, with increasing friction force;
Described heading 4 upper half part are sphere, and lower half portion is the conical surface, are beneficial to back down friction compressing tablet 2.
The present invention in use, arresting subbase 1 inserts friction compressing tablet 2 upper ends in the hole or gap on wall 8, pull down draw ring 7, make to head a ball 4 back down friction compressing tablet 2 near hole or gap wall, under the effect of frictional force, locking sleeve makes it can not deviate from hole or gap.After pulling down the pulling force disappearance of draw ring 7, draw pin return under spring 6 effects, friction compressing tablet 2 return under the effect of shell fragment 3, is pulled outwardly expansion sleeve and can makes it deviate from hole or gap.
Adopt the present invention, the locking device that is hung with decoration can be inserted in the hole on ceiling and unclamps, remove from as the troublesome operation by EXPANSION ANCHOR BOLTS; In climber or high-lift operation, this device is injected to eminence hole internal locking, keep tension force to decline from eminence, to eliminating tension force behind destination, can reclaim rope; Unloading goods, can be inserted in the hole internal locking on goods with this device locking from high to lower, and goods touches behind lower ground, and locking device release is broken off relations, without special messenger's release down below; When traction one object advances, be when non-stop state need to be removed traction thing, available this device locking is pulled thing, as long as make to be pulled thing speed, is greater than traction thing, and locking device will break off relations in release.
The present invention is not limited to above-mentioned mode of execution, and anyone should learn the technological scheme identical or close with the present invention of making under enlightenment of the present invention, within all falling into protection scope of the present invention.
The technology that the present invention does not describe in detail, shape, structure are partly known technology.
