Description

Portable rack lock

The utility model relates to a kind of rack equipment lock, and particularly a kind of rack lock that is used for communication apparatus also can be applied to the ordinary file cabinet.

Existing communication apparatus or power supply unit are placed in the more perfect machine room of safety measure usually, in debugging and the process safeguarded, need often open repeatedly cabinet door, if each debugging all must open or close with key, then very inconveniently there is no need again.Therefore wish to have a kind of rack lock, can just play fixing and convenient effect of opening without key, also can use the key lock door where necessary, but the employed door lock of cabinet of communication equipment is come from the transplanting of office furniture such as file cabinet mostly now, is not suitable for above-mentioned actual needs.

The purpose of this utility model is to provide a kind of lock of rack easily, under normal conditions, can just open door without key, and lock only plays the effect of location and door handle, Convenient switch; Also can re-use key in addition with door locked, to step up security.

The utility model comprises lock, rack and pinion drive mechanism, also comprises handling device and spring locking mechanism.

Described handling device is made up of handle, rotating shaft and spring; Be connected by rivet between handle and the rotating shaft, after the circular hole of lock upper end is passed in rotating shaft, its end is connected with rack and pinion drive mechanism, when handle rotates, the motion of driven gear rack gear, spring can make handle eject when release lever between handle and rotating shaft, and in an acute angle with lock.

Described spring locking mechanism is made up of button, stage clip, button guide strip, latch bolt block and buckle; The button guide strip is installed in the back side of lock, and button is connected the lower end of button guide strip by screw, and stage clip is installed on the stem stem of button guide strip upper end; Latch bolt block is connected with screw with the button guide strip by the rectangular enclosure in the lock, and is installed in the front of lock; Buckle is installed on the handle.

Described rack and pinion drive mechanism comprises gear and tooth bar.

In addition, for realizing using the purpose of key with door locked, the utility model can also comprise the lock core locking mechanism.Described lock core locking mechanism is made up of lock core and hasp; Lock core is made up of dead bolt and cam, and is installed in the circular hole of handle, at its lower end; Hasp is fixed in the front of lock.

The utility model adopts the frame mode of handling device locking, door lock and door handle are integrated, lock locks handling device, and lock leaves, and handle ejects, the convenient unlatching, the utility model is novel, and compact conformation is installed simply attractive in appearance, overcome the deficiency of existing door lock, reached the purpose of safe and convenient use.

Further describe the utility model below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 be the B of Fig. 1 to view, promptly be locked in the part one rack and pinion drive mechanism schematic diagram in the door;

Fig. 3 be the A of Fig. 1 to view, promptly be locked in front view outdoors.

Fig. 4 is a working state figure of the present utility model.

As shown in Figure 1, lock 1 is fixedly mounted on the left front usually, handle 201 is connected with rotating shaft 202 usefulness rivets, the circular hole of lock 1 upper end is passed in rotating shaft 202, its end is installed with rack and pinion drive mechanism, the rotating band moving gear 501 of handle 201 rotates, and drives keeper by tooth bar 502 and moves up and down, and reaches and opens or fasten with a bolt or latch the purpose of closing cabinet door.For reducing to rub and reach the effect of self-lubricating, the utility model also is equipped with plastic bushing in lock 1 upper end holds the circular hole of rotating shaft 202, certainly, can also adopt other that lining of similar effect is arranged.

Fig. 2 has clearly provided the schematic diagram that is installed in the rack and pinion drive mechanism in the cabinet door, and tooth bar 502 is incorporate with keeper, and they both can form with the materials processing of a slender bodies, coupled together after also can processing respectively again.

Fig. 3 has provided overall appearance figure of the present utility model.Spring locking mechanism and lock core locking mechanism are contained on lock 1 and the handling device in all, compact conformation not only, and also it is elegant in appearance also to seem in appearance after installation, and the width that Fig. 3 demonstrates whole lock also only is exactly the width of lock 1.Owing to adopt rack and pinion drive mechanism, also make an inner structure very compact, the width of its width and lock 1 is close.Therefore whole lock can be installed on very narrow left front.

In conjunction with Fig. 1 and Fig. 4, further describe the course of work of the present utility model.

The spring locking mechanism relies on the elasticity of stage clip 302 to guarantee certain stroke, to reach lock function.Latch bolt block 304 is fixed on the button guide strip 303 by the rectangular enclosure in the lock 1, and the lower end of button guide strip 303 and button 301 are connected and are installed in the back side of lock 1.When upwards promoting button 301, make on the button guide strip 303 and move, stage clip 302 is compressed, and moves on the while latch bolt block 304 itself and the buckle 305 that is positioned on the handle 201 are broken away from.Under the effect of spring 203, handle 201 pops up, and at this moment can open door by rotary handle 201.When needs are closed cabinet door, with handle 201 spinning reductions, and press pressing spring 203, so move on the wedge surface promotion latch bolt block 304 of buckle 305 by latch bolt block 304, under the elastic force of stage clip 302, make latch bolt block 304 fasten buckle 305 then, this moment, cabinet door was shut.

The lock core locking mechanism drives the length travel of dead bolt 402 to reach lock function by the rotation of lock core 401.Lock core 401 is fixedly mounted in the circular hole of handle 201 lower ends, and lock core 401 rotations are stretched out dead bolt 402, are embedded in hasp 403 places of being fixed in lock 1 front, realize the locking of lock 1 and handle 201 thus.

As mentioned above, two groups of mechanisms are relatively independent, can lock handle 201 respectively.

Simultaneously, two groups of mechanisms are interrelated again, and promptly the lock core locking mechanism has restraining function to the spring locking mechanism.In case by lock core 401 lock handles 201, though this moment pressing button 301, stage clip 302 compression makes latch bolt block 304 break away from buckles 305, also can't allow handle 201 pop up, and can't open door, thereby reach the purpose of further control.And when the lock core locking mechanism is opened, promptly use key rotary locking cylinder 401, make dead bolt 402 withdrawal break away from hasps 403 after, the spring locking mechanism just can freely be controlled handle 201, gives the user to greatly facilitate.

By above structure as can be known, the locking by lock core 401 can thorough locked rack, plays the effect of safety precaution, when not needing locked rack, can open, close cabinet door by the spring locking mechanism easily repeatedly.

If in the fairly perfect place of safety measure, for example in plant area, machine-operated building or housing unit, the utility model can also save the lock core locking mechanism, only realizes the locking of door by the spring locking mechanism, can make things convenient for, open the door repeatedly and close the door.
