Description
Technical field
The present invention relates to passenger train safety hanging locking technical fields, and in particular to it is a kind of for EMU ceiling can
Stretch anti-loose safety hanging locking device.
Background technique
Ceiling in existing high-speed EMUs, due to needing to overhaul the functional component above roof, above roof
It needs often to be turned on and off.During folding, easily it is not closed completely or even the phenomenon that top plate loosens.Therefore, make
It is required to guarantee that ceiling cannot be unexpected during train high-speed cruising using safeguard construction for the ceiling of inspection door form
It falls off and injures passenger.
Currently, there are mainly two types of the safeguard constructions used above ceiling: one kind is safety rope form, and one kind is hook-shaped
Formula.
Safety rope form: safety rope hanger, centre connection safety rope are respectively installed on flat-top framework and ceiling.Flat-top
Plate pulls ceiling by safety rope in improper opening and guarantees safety.This kind of safety rope in ceiling work progress more
It is convenient, but easily occur forgetting the case where hanging up properly safety rope again when ceiling opening turns off, there are security risks.
Hook form: hook, ceiling two hook in improper opening are respectively installed on flat-top framework and ceiling
Occlusion, it is ensured that safety, form is relatively simple, and practicability is good.But disadvantage is to link up with excessive height, and whole height is about 95mm.
Since the height between air-conditioning and ceiling upper surface is typically about 70-90mm, it is waited in smaller space below air-conditioning
Ceiling is not available this hook form.
Both the above safeguard construction respectively has advantage and disadvantage, the ceiling being used at different location, so that in ceiling installation
Safeguard construction form cannot completely unify.Therefore, it is necessary to research and develop a kind of novel anti-loose safety hanging locking device, to meet
There is the demand that ceiling is installed at position.
Summary of the invention
In order to solve the problems, such as to loosen caused by safety rope neglected loading, misloading existing for existing safety rope form and existing extension
The existing hook excessive height of hook forms is unsuitable for the technical issues of smaller spaces such as air-conditioning lower section use, and the present invention provides one kind
Telescopic anti-loose safety hanging locking device, not only acts as the effect for preventing ceiling from falling off, and can satisfy all positions
Set the installation requirements at place.
The technical solution adopted for solving the technical problem of the present invention is as follows:
A kind of telescopic anti-loose safety hanging locking device comprising mounting base, lock body, lower rotary shaft, pressure spring, lock core, length
Spring and short spring, the lock core include lock tongue, pin shaft, limit button and upper shaft；Upper end sets that there are two the in the middle part of mounting base
Four angles of one axis hole, mounting base are respectively provided with a mounting hole；Lock body two sides are respectively provided with a top-down slideway, under lock body
The front end in portion is lower than rear end, and the two sides of lock body lower front part are respectively provided with second axis hole, and lock body lower part rear end sets that there are two recessed
Slot, lock body are equipped with a hanging plate to lock body internal stretch between two grooves；Lock body lower part passes through the second axis hole, lower rotary shaft
Cooperation and mounting base with first shaft hole are rotatablely connected；It is covered on lower rotary shaft in the middle part of pressure spring, the lower support of pressure spring is being installed
On seat, the top of pressure spring is withstood on the lower part rear end face of lock body, and in two grooves；The front panel top of lock tongue, which is equipped with, to hang
Hook, the two sides upper panel of lock tongue are equipped with third axis hole, and the two sides lower panels of lock tongue are equipped with two groups of parallel pin holes, under lock tongue
Portion is slidably connected by the cooperation and lock body of pin shaft, pin hole and slideway；The top of limit button is set there are two the 4th axis hole, is limited
The lower part of button is set there are two card slot, and the middle part front end of limit button is equipped with a spring groove, and limit button passes through upper shaft, the
The cooperation of Triaxial hole and the 4th axis hole and lock tongue are rotatablely connected；The upper end of long spring is hung in upper shaft, the lower end cap of long spring
On hanging plate, the drift of long spring is less than the length of slideway；Short spring is placed in spring groove, and one end of short spring is withstood on
On the inner face of lock tongue front panel, the other end of short spring is withstood on the bottom surface of spring groove.
The beneficial effects of the present invention are: safety hanging locking device of the invention reduces the height of safety hanging locking, using can stretch
The long spring of contracting makes up the height of reduction, so that the safety hanging locking device is not limited by a space using position.The present invention is logical
Turnover mounting base is crossed to realize the function of ceiling unlock, and increases the stretchable lock core with self-locking function, makes to put down
It is more convenient when top plate is taken.The present invention will be made into arc chord angle appropriate at the hook of lock tongue, convenient when ceiling is closed
Hook, which is hit, to be imported.
