Abstract
The utility model relates to a locking device used for a vehicle in traffic vehicle. The locking device comprises a latch hook, a nut installed with a roller and a nut sleeve connected with a door leaf, wherein the latch hook blocks the roller or a bulge on the nut for locking the door leaf and limiting the nut and the nut sleeve to relatively rotate within a limited angle. The locking device disclosed by the utility model effectively overcomes a problem that an extra power source is needed in the prior art to realize the locking and unlocking of the door leaf in the prior art. The utility model provides the locking device which is simple to manufacture and convenient to operate. Besides, the locking device has characteristics of compact structure, small installation space, stable and reliable performance and the like, and is energy-saving and efficient, capable of avoiding occurrence of faults.
Description
Technical field
The utility model relates to a kind of locking device for field of traffic list fan or double door, belong to door leaf locking device technique field.
Background technology
Adopt at present the door system of the driving mechanism of spindle drive, there is locking and release problem always, conventional various brakes or the locking that is locked into row door system and the release that are driven by electromagnetism, hydraulic pressure, the mode such as pneumatic, its release often needs other power source.This causes whole mechanism complexity, and expense is high, poor reliability.
Utility model content
Utility model object: the purpose of this utility model is to provide a kind of simple and reliable, easy to operate for adopting the locking device of door system of spindle drive.
Technical scheme: the utility model adopts following technical scheme to realize:
A kind of locking device for field of traffic vehicle, comprise main shaft, nut sleeve, nut, latch hook, latch hook is arranged on car door top, nut is arranged in nut sleeve and can in nut sleeve, rotates, main shaft is through nut, and door leaf is connected with nut sleeve, and projection is set on nut, in the time that door leaf cuts out, latch hook hooks projection.
Also comprise torsion spring, torsion spring is arranged between nut and nut sleeve.
Also comprise the limiting plate that limits nut rotation angle, on the edge of nut, arc notch is set, one end of limiting plate is fixedly installed in nut sleeve, and the other end stretches in arc notch.
Described projection is roller.
Beneficial effect: compared with prior art, it utilizes latch hook opposite house to carry out locking to the utility model, simple in structure, is easy to safeguard, stable and reliable for performance, failure rate is low.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is this locking device exploded perspective view.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
The utility model relates to a kind of locking device for field of traffic vehicle, as shown in Figure 1, comprise main shaft 11, nut sleeve 3, nut 5, latch hook 9, latch hook 9 is arranged on car door top, and nut 5 is arranged in nut sleeve 3 and can be in the interior rotation of nut sleeve 3, and main shaft 11 is through nut 5, door leaf is connected with nut sleeve 3, on nut 5, projection is set, in the time that door leaf cuts out, latch hook 9 hooks projection.
The utility model also comprises torsion spring 12, and torsion spring 12 is arranged between nut 5 and nut sleeve 3, and contrast Fig. 2, arranges after torsion spring, and the relative nut sleeve 3 of nut 5 often remains on a side that limits rotational angle.
The utility model also comprises the limiting plate 13 that limits nut 5 rotational angles, on the edge of nut 5, arc notch is set, one end of limiting plate is fixedly installed in nut sleeve 3, the other end stretches in arc notch, nut 5 will stop operating after turning an angle like this, extends the application life of torsion spring.
Projection described in the utility model is roller 7.
Illustrate below by an example:
At closing time, main shaft 11 rotarily drives nut 5 and nut sleeve 3, and nut sleeve 3 drives door leaf to close the door, and approaching while closing the door position, roller 7 is encountered on the inclined-plane of latch hook 9, and main shaft 11 overcomes torsion spring 12 active forces and drives door leafs to continue to close the door.In the time being closed the door in position in door leaf arrival, main shaft 11, nut sleeve 3 are not all rotated, and drive roller 7 to turn to locked position at torsion spring 12 active force lower nuts 5, and latch hook 9 blocks roller 7, pins door leaf.The starting stage of opening the door, roller 1 is produced latch hook 9 by the active force that main shaft 11 first overcomes torsion spring 12, then main shaft, and 11 continue to drive nut 5, nut sleeve 3 and door leaf to open the door.
As shown in Figure 2, between nut sleeve 3 and nut 5, bearing 14 is set, two ends respectively arrange the spacer ring 15 of rigid bearing position, have so reduced the frictional force between nut sleeve 3 and nut 5, and device running is more smooth and easy.
In the utility model, roller 7 can be substituted by a projection being installed on nut 5, can realize equally the function of locking and release.
