Description

Three-card lock

Technical Field

The utility model relates to a tool to lock technical field specifically is a three calorie of locks.

Background

The three-card lock is mainly used in exhibition halls and in various exhibition and display processes as an important main body part of various section bar structure connecting and fastening pieces, and two or more aluminum sections with different lap joint directions and different or same end surface shapes are inserted into the hook claws of the section bar notches to realize the metal locking pieces which are connected with each other after the opening motion reaches the fastening effect.

At present, three calories of locks on the market rely on the lock shell to extend the open range of claw of spacing angle change, receive its angle size influence, because the extension of lock shell is spacing can take place to warp to influence result of use and life, the spacing angle size of extension of lock shell can lead to colluding the claw not at same level, increases the difficult nature during installation, consequently, need for a three calories of locks to solve above-mentioned problem urgently.

SUMMERY OF THE UTILITY MODEL

The technique that exists is not enough to the aforesaid, the utility model aims at providing a simple to operate, stable in structure's a three calorie of locks to solve the problem that provides in the background art.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a three-clamping lock, including casing, three-clamping reed and eccentric wheel, the casing includes shell and back of the lock, three-clamping reed is installed inside the casing, be equipped with mounting hole one on the shell, be equipped with mounting hole two on the three-clamping reed, be equipped with mounting hole three on the back of the lock, the eccentric wheel from the top down passes mounting hole one, mounting hole two and mounting hole three in proper order and installs in the casing, the spring has been cup jointed on the eccentric wheel, three-clamping reed includes positive foot and anti-foot, the last one end symmetry of back of the lock is equipped with the mount table, be equipped with the bolt on the mount table.

As a modification, the spring is located between the three-card spring plate and the lock back.

As an improvement, the positive pins are symmetrically distributed on two sides of the three-clip reed, and the reverse pin is positioned between the two positive pins.

As an improvement, the bolt is positioned between the positive leg and the negative leg.

As an improvement, a lock hole is formed in the upper end of the eccentric wheel, and one end, close to the lock hole, of the eccentric wheel extends to the outside of the shell.

The beneficial effects of the utility model reside in that:

the utility model discloses the bolt that sets up need not rely on the spacing angle of extension of shell and lock back of the body to change the positive foot and the range of opening of anti-foot, can not lead to positive foot and anti-foot not at same level because of the size of the spacing angle of extension of shell and lock back of the body, is difficult for stretching shell and lock back of the body and warp, adjusts the foot well by the bolt and anti-foot is unified to produce the apical force, and the atress level increases, has prolonged life, and it is more convenient to install, and is more stable.
