Abstract
The invention relates to a pressing force adjustable type cabin door locking device. According to the device, a design scheme with thread transmission combined with an inner and outer lock sleeve servo system is adopted, a lock tongue and a lock shaft form a thread transmission mechanism, and meanwhile the end face of the lock tongue and an outer lock sleeve form the servo system. When the device is used, the outer lock sleeve is rotated to enable the threaded lock tongue to be rotated to be at a closing angle, then the lock shaft is rotated to drive a cabin door to continue to move in the locking direction by means of thread transmission, and then locking of the cabin door is achieved under the combined action of the lock shaft and the threaded lock tongue; the process of closing a cabin door cover is contrary to the opening process. The pressing force adjustable type cabin door locking device achieves pressing with a trapezoid transmission thread lead screw mechanism, and is adjustable in locking stroke, reliable in sealing, simple in structure, easy and convenient to operate, small in occupied space, and suitable for being applied to various special vehicles and special equipment with high requirements for cabin door sealing.
Description
Technical field
The present invention relates to a kind of hatch door blocking device of adjustable thrust.
Background technology
At present, domestic special vehicle cabin door lock mainly contains two class formations according to different instructions for uses.
The first kind: seal request is high, does not allow the environment for use of run, drip, leak.This type of hatch door blocking device generally adopts thread transmission, and block action design is divided into first closes two steps of rear locking.Its advantage, for locking adjustment stroke is larger, seals reliable.Shortcoming is complicated structure, and the space of install required installation, controlling is larger, can only using compared with significant points on special vehicle.
Equations of The Second Kind: sealing requirements is not high.This type of cabin door lock adopts cammed surface compressing structure more, and feature is for closing i.e. realization locking simultaneously.Structural advantages: simple in structure, easy to operate.Structural disadvantages: locking stroke is very limited, and sealing is poor, and reliability is low.
Summary of the invention
For above-mentioned situation, the object of this invention is to provide that a kind of sealing is high, reliability is high, simple in structure, easy and simple to handle, and can be on special vehicle whole a kind of hatch door blocking devices of position application.
This hatch door blocking device comprises: axle sleeve 1, lock shaft 2, exterior lock tube 3, screw thread dead bolt 4, nut 5, and wherein, axle sleeve 1 is enclosed within lock shaft 2 one end, and lock shaft is provided with trapezoidal thread, and lock shaft 2 is through exterior lock tube 3 and screw thread dead bolt 4, fixing with nut 5; Exterior lock tube entangles screw thread dead bolt; Screw thread dead bolt and lock shaft form thread transmission, and screw thread dead bolt end face and exterior lock tube form follower.
The operating principle of hatch door blocking device: adopted the design scheme that screw thread transmission is combined with interior exterior lock tube servomechanism, dead bolt and lock shaft form thread transmission, and dead bolt end face and exterior lock tube form servomechanism simultaneously.During use, by rotating exterior lock tube, screw thread dead bolt is rotated to after closing angle, then rotate lock shaft, utilize screw thread gearing to drive hatch door to continue the movement in locking direction, under the acting in conjunction of lock shaft and screw thread dead bolt, realize hatch door locking.The process of closing chamber door closure 8 is contrary with opening procedure.
The invention has the advantages that 1, adopt trapezoidal motion thread screw mechanism to compress, locking stroke is adjustable, and sealing is reliable.2, simple in structure.3, easy and simple to handle.4, take up room littlely, be suitable for hatch door to be sealed with on all kinds of special vehicles, equipment special of high requirement and to apply.

The specific embodiment
This hatch door blocking device comprises: axle sleeve 1, lock shaft 2, exterior lock tube 3, screw thread dead bolt 4, nut 5, and wherein, axle sleeve 1 is enclosed within lock shaft 2 one end, and lock shaft is provided with trapezoidal thread, and lock shaft 2 is through exterior lock tube 3 and screw thread dead bolt 4, fixing with nut 5; Exterior lock tube entangles screw thread dead bolt; Screw thread dead bolt and lock shaft form thread transmission, and screw thread dead bolt end face and exterior lock tube form follower.
Close: close hatch door and compress (must compress hatch door and press seal groove to guarantee that screw thread dead bolt can rotate smoothly), clockwise rotate exterior lock tube, exterior lock tube drives dead bolt rotation to press seal groove (limited location piece on seal groove), realizes hatch door and closes.
Locking: use the special tool lock shaft that turns clockwise, the mutual motion by the trapezoidal motion thread on lock shaft and the screw thread on dead bolt realizes hatch door and locks.
Open: be rotated counterclockwise lock shaft, gap between dead bolt and seal groove is increased, progressively loosen locking, be then rotated counterclockwise 90 ° of exterior lock tubes, exterior lock tube drives dead bolt rotation to departing from seal groove, and now hatch door is opened.
Adopted screw thread transmission and the design that interior exterior lock tube servomechanism combines, utilized dead bolt cammed surface to realize hatch door locking, utilized screw thread relative motion between screw thread lock shaft and dead bolt to realize hatch door and further lock.It is adjustable that this structure design makes to lock stroke, and hatch door sealing is reliable, and delicate structure, and overall volume is little, take and operating space little.
