Fig. 2 is axonometric drawing of the present utility model;
Fig. 3 is locking (driving) schematic diagram that adopts the utility model to carry out Special working device;
Fig. 4 is the Special working device working state schematic representation in Fig. 3.
Detailed description of the invention
Referring to Fig. 1 and Fig. 2, this locking device comprises the compositions such as lock body 51, spring 52, lock pin 53, dead bolt 54, circlip 55, plug screw 56, cover plate 57, bolt 58, spring washer 59.
Lock pin 53 is contained in the first circular hole of lock body 51 and can horizontally slips, and spring 52 is contained in the circular hole of lock pin 53, spring 52 is compressed and produces certain thrust after covering cover plate 57, and under the thrust of spring 52, lock pin 53 remains to the thrust of dead bolt 54 directions.Dead bolt 54 is contained in second circular hole vertical with the first circular hole of lock body 51, can slide up and down the inclined-plane laminating of the lower inclined plane of dead bolt 54 and lock pin 53.Circlip 55 is arranged on the position, aperture of one end of the exposed dead bolt of the second circular hole, and effect is to limit the position of dead bolt 54 to prevent that it from deviating from lock body 57.Plug screw 56 is arranged on the other end of the second circular hole, and effect is, after assembling, lock body 51 is carried out to shutoff, prevents that impurity from entering.The effect of cover plate 57 is Compress Springs 52 and lock body 51 carried out to shutoff, and bolt 58 is for fastening cover plate 57, and spring washer 59 gets loose for preventing bolt 58.
Dead bolt 54 exposed parts have A, two inclined-planes of B, B inclined-plane for guiding, parallel with the lower inclined plane of dead bolt 54, A inclined-plane for locking, be positioned at B inclined-plane to opposite.B bevel angle is less, convenient compression dead bolt, and A bevel angle is slightly large, with large latching force once.The end face of dead bolt 54 in lock body 51 is also designed to inclined-plane, under the effect of wedge, can obtain larger latching force with less spring force, by the setting of angle, at least can obtain the latching force that is three times in spring force, as adopt the spring of thrust 500N can obtain the latching force of 1500N, thus make this locking device there is small-sized, light-weighted feature.
The operating principle of this locking device:
Referring to Fig. 2, when having the external force that is greater than locking device latching force (size of this power is determined by project organization and spring force) when the directive effect perpendicular to dead bolt 54 axis is on the inclined-plane of dead bolt 54, when external force F as shown in Figure 2 acts on the B inclined-plane of dead bolt 54 or external force N and acts on the A inclined-plane of dead bolt 54, capital compression dead bolt 54, after dead bolt 54 pressurizeds, under the guiding of lock body 51 endoporus, move downward, the lower inclined plane of dead bolt 54 and lock pin 53 inclined-plane laminatings, extruding lock pin 53 Compress Springs 52 are to left movement, until dead bolt 54 exposed parts are retracted; After external force action disappears, spring 52 promotes lock pin 53 and moves right, and lock pin 53 moves up to extended position by slope driving dead bolt 54; If external force action is less than locking device latching force, be applied to power on spring 52 by dead bolt 54 and lock pin 53 and be not enough to Compress Spring 52 and bounce back, dead bolt 54 also can not bounce back, and keeps lock-out state.
Below taking locking movement in vertical direction Special working device as example, in conjunction with Fig. 3 and Fig. 4, detailed description of the invention of the present utility model is described further.
Referring to Fig. 3, locking device 5 is arranged on the locking device mount pad 2 being connected with automobile frame 1, and Special working device 4 moves up and down shown in arrow in can be by figure under the driving of hydraulic jack 3, realizes the conversion of driving states and duty.In the time that Special working device 4 is in the lock state, the A inclined-plane of dead bolt and the laminating of the D inclined-plane of Special working device in locking device 5, the latching force of design locking device 5 is greater than the weight of Special working device 4, and Special working device 4 is locked can not fall.
Referring to Fig. 4, in the time that special purpose device is worked, the dead bolt retraction that moves downward compression locking device 5 under the effect of hydraulic jack 3 thrusts is realized automatic unlocking; Special working device 4 stretches out and carries out work, when after hours, Special working device 4 under the pulling force effect of hydraulic jack 3 on receive, when receiving on Special working device 4 that starting to compress dead bolt after its C inclined-plane contacts with the B inclined-plane of the dead bolt of locking device 5 bounces back, after receiving position on special purpose device 4, cross dead bolt, dead bolt ejects voluntarily Special working device 4 is locked.
Locking device 4 levels are installed, can be for the Special working device of locking horizontal movement, under the inertia force effect of Special working device when the service brake, go out forward in order to preventing.
