Abstract

The utility model belongs to the class of locks which is a drawer interlock self-locking device used on one or two drawer switches comprising an interlock device and a self-locking device, being characterized in that the self-locking device is a plurality of separate self-locking hooks and the interlock device consists of a positioning bar, a shifting fork, an interlocker comprising a plane and an inclined plane, and an interlock button. The interlocker is a rotating switch which is arranged in the location hole of the positioning bar combining with the right angled plate on the top of the interlock button keeping moving. The lock hook of the self-locking device is arranged in the interlock hole and matches the position of the lock hook of the self-locking hook. The utility model realizes the interlocking of a plurality of drawers through the positioning bar, interlocker and the interlock button, the interlocker using the rotating switch and realizing the linkage of the interlock button according to the lever rule with small friction force and can be unlocked and locked relaxedly; the self-locking device combines with the interlock button and can realize the independent self-locking in the state of interlocking.

Description

Drawer interlocking self-locking mechanism

Technical field

The utility model belongs to lockset kind, specifically is a kind of drawer interlocking self-locking mechanism that is used for two or more drawer switches.

Background technology

At tool car, Tool Cabinet, the tool box, usually have a plurality of drawers in the products such as Tools Table, these drawers generally adopt independently tapered end, manufacturing cost height not only, and use is convenient inadequately, so often consider interlocking mechanism at present, promptly adopt single tapered end to carry out the unified locking control of a plurality of drawers in conjunction with interlocking segment, in case its major defect is tapered end and has been in lockup state, each drawer status just can not change again, this mainly causes owing to lacking self-locking structure, if the user does not think to open simultaneously all drawers, can not realize, have certain limitation so this structure is used, underaction is convenient; Owing to existing interlocking mechanism complicated in mechanical structure, the free gap is big behind the locking simultaneously, and the anti-destructive ability is poor.

Summary of the invention

The purpose of this utility model is the deficiency at existing technology, a kind of more reasonable structure is provided, uses more convenient, as to be used for the double self-locking of a plurality of drawer interlocking drawer interlocking self-locking mechanism.

The technical solution of the utility model is as follows:

A kind of drawer interlocking self-locking mechanism, comprise interlock and self-locking device, it is characterized in that: self-locking device is a plurality of independently self-locking latch hooks, interlock is buckled by positioning strip, interlocker, interlocking and is constituted, interlocker is a rotating switch, is installed in the locating hole of positioning strip, cooperates interlock with the right-angle connecting plate of interlocking end of thread portion, interlocking is buckled the hook lock of self-locking device, and is corresponding with the position of self-locking latch hook.

The self-locking latch hook of self-locking device of the present utility model can be fixing latch hook, also can be movable latch hook.

The utility model is buckled the interlocking of realizing a plurality of drawers by positioning strip, interlocker, interlocking, and interlocker adopts rotating switch, when rotating rotating switch, because lever principle, the interlocking button is realized interlock, and this structure frictional force is little, feels free and relaxed when opening and closing; Self-locking device cooperates with the interlocking button, can realize the independent self-locking under the Interlock Status.The utility model is simple in structure, and is easily manufactured, and cost is low, and anti-destructive external force ability improves greatly.

The specific embodiment

Embodiment as shown in Figure 1, a kind of drawer interlocking self-locking mechanism, comprise interlock and self-locking device, it is characterized in that: self-locking device is a plurality of independently self-locking latch hooks, and interlock is made of positioning strip 1, interlocker 2, interlocking button 4, and interlocker 2 is a rotating switch (as shown in Figure 3), be installed in the locating hole of positioning strip 1, cooperate interlock with the right-angle connecting plate 3 of interlocking button 4 ends, the hook lock 5 of self-locking device is arranged on the interlocking button 4, corresponding with the position of self-locking latch hook; Wherein the self-locking latch hook is fixing latch hook 6, and is stiff, as shown in Figure 4.

Embodiment as shown in Figure 2, a kind of drawer interlocking self-locking mechanism, comprise interlock and self-locking device, it is characterized in that: self-locking device is a plurality of independently self-locking latch hooks, and interlock is made of positioning strip 1, interlocker 2, interlocking button 4, and interlocker 2 is a rotating switch, be installed in the locating hole of positioning strip 1, cooperate interlock with the right-angle connecting plate 3 of interlocking button 4 ends, the hook lock 5 of self-locking device is arranged on the interlocking button 4, corresponding with the position of self-locking latch hook; Wherein the self-locking latch hook is movable latch hook 7, and as shown in Figure 5, movable latch hook 7 is made of hook seat 8, hook sheet 9, and hook sheet 9 is fixed on the hook seat 8 by rotating shaft 10, can rotate around hook seat 8.

Self-locking latch hook of the present utility model is contained in drawer 11 trailing flanks, is used respectively with interlocking mechanism, and when they were opened in interlocking mechanism, drawer just can be extracted out.Movable latch hook 7 and fixedly latch hook 6 differences be: when interlocking mechanism closed, movable latch hook drawer can advance, and drawer is pinned; And fixing latch hook drawer, interlocking mechanism closes, and drawer can not be advanced to pin, and when having only interlocking mechanism to open, just can advance, and closes interlocking mechanism then, and drawer just is lockable.
