Abstract

The utility model belongs to an improved linkage mechanism of a special lock. The existing linkage mechanism of the special lock has the disadvantages of complicated structure and large occupation area. Both sides of a lock body are provided with two groups of guide grooves; the inner ends of an upper draw rod and a lower draw rod are movably matched with a handle by a short pin; the outer end of the upper draw rod is connected with the outer end of the lower draw rod by a long pin; the long pin can pass through the guide grooves corresponding to the long pin and can slide in the guide grooves. The mechanism has the advantages of compact structure, little occupation space, etc. The utility model can be widely used in the special lock of a machine cabinet in the communication equipment, the electronic equipment, the electric power equipment, etc.

Description

Special-purpose lock interlinked mechanism

The utility model belongs to the interlinked mechanism of special-purpose lock, relates to a kind of improvement technical scheme of special-purpose lock interlinked mechanism.

Be used in the special use lock of racks such as communication, electronics, power equipment at present, its interlinked mechanism part generally adopts rotating pull handle and drives locking bar by connector and moves back and forth, with unlatching and the closure that realizes locking.As the patent No. is the serial verb construction that 96102960.9 Chinese patent just discloses a kind of aforesaid special-purpose lock.But the fit structure of its upper and lower pull bar and locking bar is complicated; Its external handle not only takes up space, and collision is hurted sb.'s feelings easily.

The purpose of this utility model is by the improvement to special use lock interlinked mechanism, provides a kind of and can drive locking bar be synchronized with the movement when handle ejects or is pressed into lock body, thereby make special-purpose lock open closed interlinked mechanism easily.

To achieve these goals, the technical scheme of this special use lock interlinked mechanism is design like this: it comprises lock body, is hinged on handle and pull bar on the lock body.The both sides of lock body have two groups of gathering sills, and the inner of upper and lower pull bar cooperates by short pin and handle are movable, and its outer end is connected with upper and lower locking bar by having strong market potential respectively; The described gathering sill that passes correspondence of having strong market potential also can slide therein.Like this, but the stroke of gathering sill control lock bar, and upper and lower pull bar connects handle and locking bar, also can limit the position of handle, reduces rocking of handle.When handle ejected or is pressed into lock body, interlinked mechanism can drive locking bar and be synchronized with the movement.Upper and lower locking bar and snap fit can make lock be in the closure or openness state.An action can be finished the switch or the closure of lock.

Upper and lower pull bar of the present utility model be " " shape, its A/F and lock body cavity two wall width adapt, and form relation movingly, reduce gap between the two as far as possible, thereby make handle be difficult for rocking.

One return spring that is enclosed within on the lateral pin is arranged between handle of the present utility model and the lock body, and it can make handle eject automatically.The handle width matches with lock body cavity two wall width, can be built in when closing to form one in the lock body cavity, does not take space outerpace.

That this special use lock interlinked mechanism has is easy to use, compact conformation, advantage such as little takes up room, locking bar and handle are synchronized with the movement, an action can be finished the closure or openness of lock, can be widely used in the rack special lockset in fields such as communication, electronics, power equipment.

Below in conjunction with Figure of description and embodiment, the utility model is described in further detail.

Structural representation when Fig. 1 opens for the utility model;

Structural representation when Fig. 2 is the utility model closure.

As shown in the figure, comprise lock body 1, be hinged on handle 3 and upper and lower pull bar 8,4 on the lock body.The both sides of lock body have two groups of gathering sills 2,12, and the inner of upper and lower pull bar is cooperated with handle 3 activities by short pin 6,13, and its outer end 9,10 is connected with upper and lower locking bar 7,11 by having strong market potential respectively; The described gathering sill that passes correspondence of having strong market potential also can slide therein.Upper and lower pull bar 8,4 be "

" shape, its A/F and lock body cavity two wall width adapt, and make handle be difficult for rocking.Handle 3 has a return spring 5 that is enclosed within on the lateral pin 14 between upper and lower pull bar 8,4, handle is ejected automatically.The handle width matches with lock body cavity two wall width, and handle can be built in this cavity and form one when closing, and does not take space outerpace.

When closed, as shown in Figure 2, handle is built in this cavity 8,4 outermost end that are in two groups of gathering sills 2,12 of upper and lower pull bar.At this moment, the stroke maximum of upper and lower locking bar 7,11 makes whole lock be in locking state.During unlatching, as shown in Figure 1, handle 3 outwards ejects under the effect of return spring 5, drives upper and lower locking bar 7,11 by upper and lower pull bar 8,4 simultaneously and inwardly slides, up to the inner terminal of two gathering sills 2,12.At this moment, the stroke minimum between the upper and lower locking bar 7,11, whole device is in opening.
