Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Below in conjunction with Fig. 1 to 3, preferred embodiment of the present utility model is described in further detail,
As shown in Figure 1, the preferred separation type lock locking mechanism of the utility model, comprise lock housing 2 and orienting sleeve 3 and driving device, one end of driving device is connected with dead bolt 20, and the other end of driving device is connected with the other end of pilot bar 30.Lock housing 2 installation site is generally higher than orienting sleeve 3 installation site.Driving device is a kind of device of power transmission, such as: stay cord 1, connecting rod mechanism.As shown in Figure 1, driving device is stay cord 1, and one end of stay cord 1 is connected with dead bolt 20, and the other end of stay cord 1 is connected with the other end of pilot bar 30.Stay cord 1 generally adopts steel rope, also can adopt the rope of other type.
As shown in Figure 2, be provided with dead bolt 20 in lock housing 2, on dead bolt 20, cover has the first pull back spring 21.In lock housing 2, offer dead bolt pilot hole 22, dead bolt 20 and dead bolt pilot hole 22 bearing fit, the first pull back spring 21 is positioned at dead bolt pilot hole 22, first pull back spring 21 two ends and is resisted against respectively on lock housing 2 and dead bolt 20.Dead bolt pilot hole 22 can be circular hole or square hole, and dead bolt pilot hole 22 comprises macropore and aperture, and the cross section of dead bolt 20 can be square or circular, and dead bolt 20 comprises large end and small end, and large end coordinates with macropore, and small end coordinates with aperture.First pull back spring 21 one end is resisted against on the step of aperture.
As shown in Figure 3, be provided with pilot bar 30 in orienting sleeve 3, on pilot bar 30, cover has the second pull back spring 31, and one end of pilot bar 30 is connected with handle.In orienting sleeve 3, offer pilot bar pilot hole 32, pilot bar 30 and pilot bar pilot hole 32 bearing fit, the second pull back spring 31 is positioned at pilot bar pilot hole 32, second pull back spring 31 two ends respectively against on orienting sleeve 3 and pilot bar 30.Pilot bar pilot hole 32 can be circular hole or square hole, and pilot bar pilot hole 32 comprises macropore and aperture, and the cross section of pilot bar 30 can be square or circular, and pilot bar 30 comprises large end and small end, and large end coordinates with macropore, and small end coordinates with aperture.Second pull back spring 31 one end is resisted against on the step of aperture.
As shown in Figure 3, handle is rotary type handle, and so-called rotary type handle refers to that operator realizes operation by rotary handle.Handle is connected with one end of pilot bar 30 by bearing pin 5, and handle can rotate around bearing pin 5 axis.Handle is provided with vertical plane 40, and vertical plane 40 is resisted against on the transverse plane of orienting sleeve 3, and vertical plane 40 has transition cambered surface 41 along stretching, and transition cambered surface 41 has horizontal surface 42 to horizontal direction along stretching.Horizontal surface 42 to bearing pin 5 distance between center line L2 is greater than vertical plane 40 to bearing pin 5 distance between center line L1.
When upwards pulling handle, because vertical plane 40 is resisted against on the transverse plane of orienting sleeve 3, the transverse plane of orienting sleeve 3 is as fulcrum, handle is rotated upwardly to horizontal surface 42 around bearing pin 5 axis and is resisted against on the transverse plane of orienting sleeve 3, because horizontal surface 42 to bearing pin 5 distance between center line L2 is greater than vertical plane 40 to bearing pin 5 distance between center line L1, pilot bar 30 is moved right, and the second pull back spring 31 is compressed.Now stay cord 1 pulls dead bolt 20 to move right, and the first pull back spring 21 is compressed, and dead bolt 20 is retracted, and separation type lock locking mechanism is in released state.
When pulling handle downwards, because horizontal surface 42 is resisted against on the transverse plane of orienting sleeve 3, the transverse plane of orienting sleeve 3 is as fulcrum, handle is rotated upwardly to vertical plane 40 around bearing pin 5 axis and is resisted against on the transverse plane of orienting sleeve 3, because vertical plane 40 to bearing pin 5 distance between center line L1 is less than horizontal surface 42 to bearing pin 5 distance between center line L2, under the spring-force driven dual of the second pull back spring 31, pilot bar 30 is moved to the left.Now under the spring-force driven dual of the first pull back spring 21, dead bolt 20 is moved to the left, and dead bolt 20 is stretched out, and separation type lock locking mechanism is in lockup state.
In the present embodiment scheme, owing to adopting rotary type handle, not only can be laborsaving and easy to operate, and latch functions, because vertical plane 40 and horizontal surface 42 are plane, if operator inoperation handle, separation type lock locking mechanism can not automatically return to lockup state from released state.
The utility model additionally provides the second handle, and the second handle is different from above-mentioned handle to be: on handle, be provided with eccentric cambered, eccentric cambered is resisted against on the transverse plane of orienting sleeve 3.Eccentric cambered refers to that the center of eccentric cambered does not overlap with bearing pin 5 center, and there is certain distance at center and bearing pin 5 center of eccentric cambered.
Handle of the present utility model can also adopt pull-type handle, and pull-type handle refers to that the operator power acted on handle is pulling force, is not moment.
As shown in Figures 2 and 3, stay cord 1 two ends are respectively arranged with the first joint 11 and the second joint 13, first joint 11 is threaded with dead bolt 20, and the second joint 13 is threaded with the other end of pilot bar 30.On stay cord 1, cover has the first slip cap 10 and the second slip cap 12, first slip cap 10 to be fixed in lock housing 2, and orienting sleeve 3 is provided with permanent seat 33, and the second slip cap 12 is fixed on permanent seat 33.First slip cap 10 and the second slip cap 12 pairs of stay cords 1 play fixing and directional tagging.
In addition, the utility model additionally provides a kind of construction machinery and equipment, comprises above-mentioned separation type lock locking mechanism.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
