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 the tight device of a kind of tension expansion.
Background technique
In daily life, especially in repairs profession, need permanent at ceiling or hangs as light fixture or other decorations temporarily time, generally employing EXPANSION ANCHOR BOLTS fixes, so not only install and waste time and energy, and certain infringement is caused to the hanging position such as body of wall or roof; Meanwhile, needing to unload bolt when dismantling, 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 the tight device of a kind of tension expansion.
The present invention solves its technical problem and adopts following technological scheme to realize: the tight device of a kind of tension expansion, comprise expansion sleeve and draw pin, described expansion sleeve comprises subbase, friction compressing tablet and shell fragment, at least three friction compressing tablets are provided with around subbase, described shell fragment two ends are separately fixed on friction compressing tablet and subbase, and the effect of shell fragment makes friction 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 stay column top and middle part respectively, and described both ends of the spring is connected and installed in heading in the middle part of stay column and subbase respectively, and the effect of spring makes to draw pin return; Described draw ring is arranged on stay column lower end;
Vertically be provided with cylindrical tube in the middle part of described subbase, for fixing spring, and keep-spring can not 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;
The side that described friction compressing tablet contacts with wall is 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 fast speed can hang weight, can also remove locking state at a distance, and can be used in needs to remove the constraint of object but the personnel body of being not easy to faces on-the-spot situation.
Accompanying drawing explanation
Be described in detail below in conjunction with the drawings and specific embodiments:
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, the tight device of a kind of tension expansion, comprise expansion sleeve and draw pin, described expansion sleeve comprises subbase 1, friction compressing tablet 2 and shell fragment 3, at least three friction compressing tablets 2 are provided with around subbase 1, described shell fragment 3 two ends are separately fixed on friction compressing tablet 2 and subbase 1, and the effect of shell fragment 3 makes friction 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 stay column 5 top and middle part respectively, and described spring 6 two ends are connected and installed in heading 4 in the middle part of stay column 5 and subbase 1 respectively, and the effect of spring 6 makes to draw pin return; Described draw ring 7 is arranged on stay column 5 lower end;
Vertically be provided with cylindrical tube 10 in the middle part of described subbase 1, for fixing spring 6, and keep-spring 6 can not 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;
The side that described friction compressing tablet 2 contacts with wall is evenly provided with protruding structure 9, with increasing friction force;
Described heading 4 upper half part is sphere, and lower half portion is the conical surface, is beneficial to back down friction compressing tablet 2.
The present invention in use, arrest subbase 1 in the hole on friction compressing tablet 2 upper end insertion wall 8 or gap, pull down draw ring 7, make heading 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 the pulling force pulling down draw ring 7 disappears, draw pin return under spring 6 acts on, friction compressing tablet 2 return under the effect of shell fragment 3, is pulled outwardly expansion sleeve and it can be made to deviate from hole or gap.
Adopt the present invention, the locking device being hung with decoration can be inserted in the hole on ceiling and unclamp, remove from as the troublesome operation by EXPANSION ANCHOR BOLTS; In climber or high-lift operation, this device is injected eminence hole internal locking, keep tension force to decline from eminence, behind destination, eliminate tension force can reclaim rope; Unloading goods from high to lower, can lock with this device the hole internal locking be inserted on goods, and after cargo contacts to lower ground, locking device unlocks and breaks off relations, and unlocks down below without special messenger; When traction one object advances, when non-stop state need to remove traction thing, available this device locking is pulled thing, as long as make to be pulled thing speed to be greater than traction thing, locking device will unlock unhook.
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 made under enlightenment of the present invention, all falls within protection scope of the present invention.
The technology that the present invention does not describe in detail, shape, structure part are known technology.
