Abstract

The utility model relates to a special lock locking/unlocking device. The existing special lock needs operating for two times at the time of locking and unlocking operation, and at the time of unlocking, the unlocking is difficult owing to failure rotation, etc. A pull handle of the utility model is connected with a lock body by a cross pin. A spring is sheathed in the cross pin and overlapped on the lock body and the pull handle. A button is connected with the other end of the lock body by the cross pin. A restoring spring is arranged between the button and the lock body. The utility model has the advantages of reasonable structure and convenient operation, and has a wide application prospect in a special lock for a cabinet of communication, electronic and electric power equipment.

Description

Special-purpose locking attaches together to be put

The utility model belongs to the closing device of special-purpose lock, relates to a kind of special-purpose locking and attaches together the improvement technical scheme of putting.

Present special-purpose locking at racks such as communication, electronics, power equipments attaches together to put and generally presses the button earlier, ejects handle, and the rotation to the left or to the right of will shaking hands is again controlled interlinked mechanism by handle and driven locking bar, opens closed purpose to reach.Owing to need rotating pull handle, and different device direction of rotation is indefinite, needs twice action when not only operating, and frequent reasons such as not in place or direction is indefinite owing to rotation when closed, makes the closed difficulty of handle, cause open closed malfunctioning.In addition, because the handle whirligig is arranged, make this unlatching close mechanism structure complicated, cost is higher, and the easy gouging abrasion of part.

The purpose of this utility model is to provide a kind of rational in infrastructure, easy to use by the improvement to handle mechanism, can drive special-purpose locking that locking bar is synchronized with the movement and attach together and put when handle ejects or is pressed into lock body.

It is to realize like this that this special-purpose locking attaches together the improvement technical scheme of putting.It comprises the lock body of being with cavity and places lock body interior handle, button.Handle is connected on the lock body by lateral pin, spring housing is in lateral pin and overlap lock body and handle respectively, and promptly an end of spring is butted on the lock body, and the other end is butted on the handle, make handle can eject or be built in the cavity of lock body, but can not rotate to the left or to the right in lock body.When locking bar cooperates with handle, can link thereupon, thereby realize the special-purpose closure or openness of locking.Button is connected the other end of lock body by lateral pin, between its bottom and lock body one return spring is arranged, and automatically resets after button is pressed; The fin of handle end matches with the groove of button end, and fin can be blocked by groove, thereby handle is built in the lock body cavity.The surface of button protrudes in the upper surface of lock body, and becomes certain tilt angle alpha with it, be convenient to touch push, and good hand touch.One lock core is arranged in the button, and a groove is arranged at the bottom of lock core, and this groove cooperates with the projection of lock body bottom correspondence position.Rotary locking cylinder can be pressed when making projection parallel with groove and unblank; When groove is vertical with projection, hinder button pressed downwards, promptly can not open lock.This lock core can prevent the false touch button and lock is opened, also can be antitheft.

This special use locking attaches together to be put by changing the connected mode of handle and lock body, has changed the original rotary movement of handle.Pressing button, handle is upspring, and makes the locking bar interlock that is mated, and realizes the unlatching of lock; When closing, push handle and make it to close in the cavity of lock body, thus closed lock.It is novel, and structure is ingenious, and is easy to use, has a wide range of applications in the special-purpose lock of the rack 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 Figure 1 and Figure 2, this special use locking attaches together to be put, and comprises the lock body 1 of being with cavity and places lock body interior handle 3, button 2.Handle 3 is connected on the lock body 1 by lateral pin 12, spring 5 is enclosed within the lateral pin 12 and overlaps lock body and handle, and promptly an end of spring 5 is butted on the lock body 1, and the other end is butted on the handle 3, make handle eject or to be built in the cavity of lock body, but can not rotate to the left or to the right.When locking bar 7,15 cooperates with handle 3 by

pull bar

8,4, can link, the special-purpose lock of realization is opened closed thereupon.Button 2 is connected the other end of lock body 1 by lateral pin 10, and its bottom and 1 of lock body have a return spring 6, can automatically reset after button 2 is pressed.The fin 13 of handle end matches with the groove 9 of button end, and fin can be blocked by groove, thereby handle 3 is fixed in the lock body cavity.The surface of button 2 protrudes in the upper surface of lock body 1, and becomes certain tilt angle alpha with it, is convenient to touch push.One lock core 11 is arranged in the button 2, and a groove is arranged at the bottom of lock core, and this groove cooperates with the projection 14 of lock body bottom correspondence position, and rotary locking cylinder 11 is unblanked can press parallel with groove of projection; Can hinder button pressed downwards when groove is vertical with projection, lock can't be opened.
