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 by positioning strip, interlocker, shift fork, connecting rod, two contigency snap closes constitute, between two interlockers connecting rod is arranged, connect by pin between connecting rod, pin is contained on the shift fork, shift fork is installed in the locating hole of positioning strip, and interlocker has a rotor and roller, and rotor is connected by pin with connecting rod, and fix by rotating shaft, rotor cooperates with the right-angle connecting plate of interlocking end of thread portion, and 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, stir shift fork, drive interlocker by connecting rod, the rotor of interlocker drives the right-angle connecting plate of interlocking end of thread portion and realizes interlocking, the utility model interlocker adopts rotation roller, utilize the rolling friction principle, frictional force is little, feels free and relaxed when opening and closing; Self-locking device cooperates with chain 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, interlock is by positioning strip 1, interlocker 2, shift fork 3, connecting rod 4, two contigency snap closes 8 constitute, as Fig. 3, shown in 4, two 2 of interlockers have connecting

rod

4,4 on connecting rod is connected by pin 5, pin 5 is contained on the shift fork 3, shift fork 3 is installed in the locating hole 6 of positioning strip 1, and interlocker 2 has a rotor 10 and roller 11, and rotor 10 is connected by pin 19 with connecting rod 4, and it is fixing by rotating shaft 12, rotor 10 cooperates with the right-angle connecting plate 7 of interlocking button 8 ends, and the hook lock 9 of self-locking device is arranged on the interlocking button 8, and is corresponding with the position of latch hook; Wherein the self-locking latch hook is fixing latch hook 13, and is stiff, as shown in Figure 5.

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, interlock is by positioning strip 1, interlocker 2, shift fork 3, connecting rod 4, two contigency snap closes 8 constitute, as Fig. 3, shown in 4, two 2 of interlockers have connecting

rod

4,4 on connecting rod has pin 5, pin 5 is contained on the shift fork 3, shift fork 3 is installed in the locating hole 6 of positioning strip 1, and interlocker 2 has a rotor 10 and roller 11, and rotor 10 is connected by pin 19 with connecting rod 4, and it is fixing by rotating shaft 12, rotor 10 cooperates with the right-angle connecting plate 7 of interlocking button 8 ends, and the hook lock 9 of self-locking device is arranged on the interlocking button 8, and is corresponding with the position of self-locking latch hook; Wherein the self-locking latch hook is movable latch hook 14, and movable latch hook 14 is made of hook seat 15, hook sheet 17, and hook sheet 17 is fixed on the hook seat 15 by rotating shaft 16, can rotate around hook seat 15, as shown in Figure 6.

Self-locking latch hook of the present utility model is contained in drawer 18 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 14 and fixedly latch hook 13 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.
