Description

A kind of large slide force locking device of realizing with flexible axle

The cabinet door lock that the utility model relates to a kind of bin tightly installs, and particularly needs the cabinet door lock of the bin of higher seal degree tightly to install.

The tight device of applied cabinet door lock mostly adopts lever principle in bins such as file cabinet, strongbox and rack at present, as shown in Figure 1, generally comprise rolling disc 101, connecting rod 102, fork 103, and movable part 104, its operating principle is roughly as follows: rolling disc 101 rotates drivening rod 102 motions, be transferred to movable part 104 according to lever principle by fork 103, make movable part 104 produce motion locking cabinet door.But reason owing to principle and member, this device ubiquity following point: the manufacturing processed complex of leverage, the tie point position is many, for making motion make the tie point gap big flexibly, so the motion noise is big, and positioning accuracy is poor, forms because lever is non deformable rigid connector, therefore the position of rolling disc and movable part can not arbitrarily change, and makes processing and design lack flexibility; In addition, the movable part slide force of this device generation is also less.

The purpose of this utility model provides a kind of simple in structure, and is easy to process, low noise, and positioning accuracy is high and can produce the locking device of large slide force, and this locking device is mainly realized with flexible axle.

The utility model comprises handle, rolling disc, movable part, reaches the motion counterpart, handle inserts the handle socket of rolling disc and is fixed on the rolling disc, movable part fixes on cabinet door inboard and guarantees that it has enough rotational angles with hinges fixing, is furnished with a motion counterpart on the correspondence position of movable part; The utility model also comprises a flexible axle between rolling disc and movable part, and axle core one end of flexible axle is fixed on the rolling disc, and the other end is fixed on the movable part, and the two ends of flexible axle outer jacket are fixed on cabinet door inboard; Drive turn disc when handle rotates, turn disc drives flexible axle axle core and slides, and the slip of flexible axle axle core drives movable part and rotates, thereby movable part imports or withdraws from the locking of motion counterpart or opens the cabinet door.

For reaching the purpose of multiple spot locking, can be on the different angles of rolling disc the fixed number cover comprise the transmission device of flexible axle, movable part and motion counterpart.

Rolling disc of the present utility model can be circular, also can make different shapes according to the quantity of transmission device, can do the triangularity rolling disc as 3 locking devices, and 5 locking devices can be made pentagon rolling disc etc.

Movable part of the present utility model is a sector belt petioliform shape, and its fan-shaped part both sides are thin, thick middle.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 2, it is a specific embodiment of the present utility model: with 4 locking devices of large slide force of flexible axle realization.201 is rolling disc, and handle socket is arranged on it, is convenient narration, and the cover in our the choosings quadruplet transmission device wherein describes for example, and 202 is flexible axle, and 203 is movable part, and 204 are the motion counterpart.Handle is inserted in the handle socket of rolling disc central authorities and is fixing, is fixing an end of four flexible axle axle cores on rolling disc 201 respectively with different angles, and the other end of each flexible axle axle core is then connecting a movable part.The two ends of flexible axle 202 outer jackets are separately fixed at the inboard of cabinet door, and movable part 203 usefulness hinges fixing fix on cabinet door inboard, and guarantee that it has enough rotational angles, correspondingly are equipped with a motion counterpart 204 at the correspondence position of movable part 203.

Fig. 3 is the structural representation of flexible axle of the present utility model.301 is flexible axle axle core, and 302 is outer jacket, and 303 is flexible axle axle core overcoat finer wire.Overcoat finer wire 303 has guaranteed that the axle core is unlikely to the flexible axle bending when sliding, injected lubrication oil between axle core and overcoat steel wire, makes the slip of a core flexible, and frictional force is minimum.

For the structure to flexible axle better describes, Fig. 4 has provided the left view of Fig. 3.

Fig. 5 is a movable part schematic diagram of the present utility model.Movable part can be made sector belt petioliform shape, the wherein both sides of fan-shaped part and middle variable thickness sample, as shown in Figure 6, both sides are thin, thick middle can guarantee that like this displacement that movable part imports in the motion counterpart changes from small to big gradually, and the power of generation is also by little increase.

When handle rotates, driving rolling disc by handle socket rotates together, the axle core that is fixed on each flexible axle on the rolling disc is along with the rotation of rolling disc is slided, the slip of axle core drives the movable part that is fixed on the other end and rotates, movable part rotates just can import or withdraw from the motion counterpart, reaches the purpose of locking or opening the cabinet door.

Thereby the utility model makes structure more simple with processing owing to adopt flexible axle to replace leverage; Because used lubrication oil in the flexible axle, joint gap is little between member, so operate lightly, noise is little and positioning accuracy is high; The size of flexible axle axle core can be from 2mm to 8mm, can produce thrust from 180N to 1000N and 2000N pulling force (SQE of Shanghai Electronic Instrument Factory series push-and-pull flexible axle product manual) to 4000N, this is especially suitable concerning the cabinet door of the higher seal degree of needs, and only need can increase the arm of force by the swelled handle size; In addition,, therefore can be suitable for the cabinet door needs of different volumes size in free space, and the installation site of rolling disc and handle can move arbitrarily, improve design, installation and processing flexibility greatly because flexible axle can arbitrarily place.
