Abstract

The utility model discloses a tool box buckle structure, in particular to an easy operation and non-easy loosing buckle structure. The buckle structure comprises a fixing seat fixedly mounted on a box body, a wrenching block, a clamping buckle element, and a buckle clamping element mounted on the box body. The wrenching block pivoted at the fixing seat can drive a clamping buckle and the buckle clamping element corresponding to the clamping buckle element to reach the aim of buckling the box body and the box cover of the tool box. The utility model has the characteristics that the bottom edge of the fixing seat is convexly extended a positioning patch whose bottom face is equipped with a clamping convex point for limiting the wrenching block. A reseting spring between the clamping buckle element and the wrenching block can effectively prevent the wrenching block to loose to improve the fastening effect of a box case and the box body and extend the service life of the tool box when the clamping buckle element disengages from the buckle clamping element of the box cover to quick reset by thedesign.

Description

The tool box fastener structures

Technical field

The utility model relates to a kind of fastener structures that is used to fasten tool box casing and case lid.

Background technology

General instrument cases or tool box, the convenience during for portable and storage can be provided with corresponding fastener structures with the free ora terminalis of case lid in casing usually, detains mutually so as to the fastener that utilizes upper and lower correspondence and pulls.Modal traditionally cramp and the button piece that is simple ejection formation, utilize the button portion of cramp to remove the direct catching groove of detaining the button piece of pulling, but such design, except cramp easily because of pull for a long time rupture, its also as easy as rolling off a log getting loose causes the user to use the inconvenience in tool box, in addition if any damage, usually need together to upgrade together with the tool box, so its service life is not long, economic benefit is also not good.

Still develop for this reason and a kind of fastener structures, it mainly lies in and is pivoted with one on the casing and pulls piece, and this is pulled piece and can drive a fastener and remove to fasten button on the case lid part of pulling, moreover this pulls piece and press and be limited on the casing, fastens and the purpose of operation so as to reaching.But this kind structure is pulled the moment that piece presses down and is reached owing to pull button between piece and the fastener simple utilization of power of pulling, and influences and gets loose so it is subject to external force factor, causes the user in operational inconvenience.

Though there is the part dealer on the tool box fastener structures, constantly to pursue and improvement, wish significantly to promote its button power of pulling nothing but, and further promote the convenience that uses, in other words, existing concrete disclosed article or preceding case, never teaching has and has the button fastener structures that effect is good and be convenient to operate of pulling concurrently, thereby remains further self-criticism, and seeks first of the feasible solution.

In view of this, the utility model people is by the research and development of being engaged in related industry for many years and manufacturing experience, deeply inquire at the problems referred to above and demand, and the scheme of actively seeking solution, through the research of long-term endeavour with study, finally success develop a kind of tool box fastener structures, use and improve the button effect of pulling, and avoid promoting the convenience of use.

The utility model content

The purpose of this utility model is to provide a kind of tool box fastener structures, its can allow button pull that part automatically resets and effectively restriction pull the piece position, thereby strengthen the button power of pulling, make fastener be difficult for getting loose.

For achieving the above object, technical solution of the present utility model is: a kind of tool box fastener structures, this fastener structures mainly are made up of the holder that is fixedly arranged on the free ora terminalis of casing, the correspondence button pulling piece, fastener and be fixedly arranged on the free ora terminalis of the case lid part of pulling; This holder root edge level has protruded out a spacer, and the spacer bottom surface is formed with a clip salient point; This is pulled piece and then utilizes hinged arm to be hubbed on the holder, be arranged with one on this hinged arm for pulling the torque spring that piece keeps down at any time, and pull button that the piece root edge inwardly protrudes out the corresponding holder spacer sheet of pulling, the button medium film section of pulling is formed with the detent of a corresponding spacer clip salient point; The hinged arm below that this fastener utilizes a pivot to be hubbed to pull piece is arranged with a back-moving spring on the pivot, this fastener apical margin forms the pull protruding button portion of part of corresponding button, and button is pulled and formed the catching groove of the protruding button of corresponding fastener portion on the part.

This holder both sides apical margin is formed with corresponding lug, also is formed with corresponding lug and pull piece, and the lug that hinged arm passes both correspondences will be pulled piece and be hubbed on the holder.

This pulls the arc guide groove that piece wherein is formed with corresponding fastener on the lug, and the end of back-moving spring passes this arc guide groove.

The inner face of this holder is formed with one can buckle piece for what torque spring was shored.

These fastener both sides are formed with the corresponding fastener that allows respectively can be hubbed at the lug of pulling on the piece.

After adopting such scheme, the utility model in use, its fastener can be pulled the effect button of piece and be pulled on button is pulled part, with the casing and the case lid in snap close tool box, is convenient to operate and fasten the good tool box fastener structures of effect thereby constitute one.In addition, the fastener of the utility model fastener structures is before untiing or not fastening, and fastener is subjected to the effect of back-moving spring, opens downwards naturally, so can allow the user when untiing fastener structures, can open voluntarily, reaches the purpose of promoting operation ease.Moreover, after the fastener button is pulled on button is pulled part, it is pulled piece and can utilize the button sheet of pulling to press on the spacer of holder, and the button of the pulling piece sheet of pulling is subjected to the restriction of spacer bottom surface clip salient point, can obtain alignment restrictions completely, makes to pull piece and can not get loose arbitrarily, so not only can improve the fastening effect of casing and case lid, and can avoid its damage, can promote its service life, further improve its economic benefit.
