Abstract
The invention discloses a safety catch used for an air-conditioning cover plate of train, which comprises the train air-conditioning cover plate and a train air conditioner rack. The invention is characterized in that the safety catch also comprises two parts of a safety buckle component and a safety ring component, the safety buckle component is arranged on the train air-conditioning cover plate, the safety ring component is arranged on the corresponding position of the train air conditioner rack, the safety buckle component can be automatically buckled with the safety ring component when the train air-conditioning plate is closed. The safety buckle component comprises a safety buckle, a connecting rod, a pedestal and a spring. The safety ring component comprises a safety ring, an installation seat and a shaft. The invention has the advantages of simple structure, reliability and easy operation; the cover plate is automatically locked when the cover plate is closed so that the security of the cover plate can be ensured during the train operation; under the condition that the air-conditioning cover plate is unlocked, the safety catch is capable of preventing the air-conditioning cover plate from flying out, so that more effective guarantee for security of train air-conditioning is added during the train operation.
Description
Technical field
The present invention discloses a kind of safety catch used for air-conditioning cover plate of train, specifically relates to the air-conditioning system sheet metal structurals such as train, subway, train.
Background technology
At present, for convenient maintenance, train air conditioning system covering plate structure is to adopt hinge to coordinate turning-bolt lock to fix substantially.Therefore locking cover plate needs each turning-bolt lock of manual rotation, thereby has certain leakage lock risk.Along with the development of Chinese Railway and city rail, more and more higher to the security performance requirement of train, so the necessity that secure latch exists also more and more comes into one's own thereupon.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of safety catch used for air-conditioning cover plate of train is provided, this device just can make, on its automatic locking, to prevent that air-conditioning cover plate from flying out when train operation, guarantee the safety of cover plate when train operation when cover plate closes.
According to technical scheme provided by the invention, safety catch used for air-conditioning cover plate of train comprises air-conditioning cover plate of train, train air-conditioning frame, feature is: also comprise safety buckle assembly, safety collar assembly two parts, described safety buckle assembly is arranged on air-conditioning cover plate of train, described safety collar assembly is arranged on the relevant position of train air-conditioning frame, when air-conditioning cover plate of train closes, described safety buckle assembly and described safety collar assembly energy automatic buckling.
As the present invention, further improve, described safety buckle assembly comprises described in safety buckle, connecting rod, pedestal and spring that safety buckle is connected by connecting rod with pedestal, mounting spring on described connecting rod.
As the present invention, further improve, described safety collar assembly comprises safety collar, mount pad and axle, and described safety collar is arranged on axle, and described axle is contained on mount pad, and at mount pad, fixedly time, safety collar can, around axle, freely rotate upward.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, reliable, easy to operate; When closing, cover plate just can make, on its automatic locking, to have guaranteed the safety of cover plate when train operation; Can not lock in the situation that, prevent that air-conditioning cover plate from flying out when train operation at air-conditioning cover plate, for the safety of train air-conditioning running is again, have one heavyly effectively to guarantee more.

The specific embodiment
Shown in Fig. 1, Fig. 2, Fig. 4, comprise air-conditioning cover plate of train 1, train air-conditioning frame 2, safety buckle assembly 3, safety collar assembly 4, safety buckle 5, connecting rod 6, pedestal 7, spring 8, safety collar 9, mount pad 10 and axle 11.
The present invention is a kind of safety catch used for air-conditioning cover plate of train, is arranged on air-conditioning cover plate 1 and air conditioner frame 2, and particular location is determined by air-conditioning unit concrete structure, referring to Fig. 1.
The present invention is comprised of safety buckle assembly 3, safety collar assembly 4 two parts, described safety buckle assembly 3 is arranged on air-conditioning cover plate of train 1, described safety collar assembly 4 is arranged on the relevant position of train air-conditioning frame 2, when air-conditioning cover plate of train 1 closes, described safety buckle assembly 3 can automatic buckling with described safety collar assembly 4.
Described safety buckle assembly 3 comprises safety buckle 5, connecting rod 6, pedestal 7 and spring 8, described safety buckle 5 is connected by connecting rod 6 with pedestal 7, the spring 8 of corresponding size is installed on described connecting rod 6, make safety buckle 5 when pedestal 7 is fixing, around connecting rod 6, rotated by a small margin by spring 8 or external force.
Described safety collar assembly 4 comprises safety collar 9, mount pad 10 and axle 11, and described safety collar 9 is arranged on axle 11, and described axle 11 is contained on mount pad 10, and at mount pad 10, fixedly time, safety collar 9 can freely rotate upward around axle 11.
Complete when the maintenance of train air-conditioning unit, shut each cover plate, now as shown in Figure 1, safety buckle assembly 3 and safety collar assembly 4 are in the duty of awaiting orders.If now turning-bolt lock is not locked because of artificial or technical failure, during train Accelerating running, under the effect of high velocity air, air-conditioning cover plate is dug, as shown in Figure 6, and safety buckle assembly 3 and safety collar assembly 4 duty in tension, guarantee that cover plate can not brandish away, cause a serious accident.When train speed reduces, air velocity reduces, and active force is corresponding to be reduced, and under the effect of cover plate gravity, cover plate can be got back to Fig. 1 state again.
When air-conditioning unit is because maintenance or other situation are need open cover plate time, first open all turning-bolt locks, then cover plate is opened certain angle (finger can stretch into), as shown in Figure 7, press the handle of safety buckle 5, safety buckle 5 and safety collar 9 are departed from, thereby can easily open air-conditioning cover plate.
