Problems solved by technology
The lanyard-type safety device described in prior art 2 is installed in an area where the flat roof 403 of the hook-type safety device 1 cannot be fixed because the safety rope can be folded.
However, when opening and closing the flat top plate 403, the safety lanyard 201 needs to be specially disassembled from the buckle end of the flat top plate 403, so the maintenance is time-consuming and laborious, and after the flat top plate 403 is closed, it is easy to miss and hang it by mistake, which will increase the fall of the flat top plate 403 The risk of injury accidents; at the same time, the safety rope 201 is a non-metallic material, which needs to be checked and replaced regularly

Embodiment Construction
[0053] In order to make the technical solutions and advantages of the embodiments of the present application clearer, the exemplary embodiments of the present application are described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and Not all examples are exhaustive. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.
[0054] The core idea of this solution is to design the hook mechanism 301 in a retractable manner, under the premise of ensuring the anti-dropping effect, greatly saving the use space above the flat top plate 403, and also facilitate the removal and installation of the flat top plate 403; The precise positioning of the hook structure ensures the accuracy and safety of the device against falling off. By designing multiple return springs, labor...

The embodiment of the invention provides an anti-dissociation device which comprises a hook mechanism 301 and a support mechanism 302, wherein the hook mechanism 301 is used for hooking a first external structure; the support mechanism 302 is used for supporting the hook mechanism 301 and is used for providing a slideway for reciprocation movement of the hook mechanism 301; one end of the supportmechanism 302 is rotationally fixed with a second external structure through a fixing mechanism 303; the other end of the support mechanism 302 is a free end; the hook mechanism 302 is matched with the slideway of the support mechanism 302 and is capable of sliding off or sliding into the support mechanism 302 from the support mechanism 302. By adopting the scheme, the anti-dissociation device canbe applied to security protection of a flat top plate 403, when the lock of the flat top plate 403 is opened or the lock of the flat top plate 403 is failed, the flat top plate 403 can be hooked by using the telescopic hook structure, and the flat top plate 403 can be effectively prevented from being dissociated to hurt people; the anti-dissociation device 3 of the scheme is good in structure adaptability, convenient to operate and widely applicable to application fields with suspended ceiling structures such as vehicles and home decoration.
Description
Technical field [0001] This application relates to railway vehicle transportation technology, and in particular, to an anti-dropping device and train carriage. Background technique [0002] The vehicle flat roof 403 is an important decorative element on the top of the high-speed rail EMU, and its setting method and installation stability directly affect the appearance and safety of the vehicle. Usually, a lot of vehicle auxiliary devices are set between the flat roof 403 and the roof rack in the car. During the maintenance of the vehicle, it is necessary to open the flat roof 403 to maintain or overhaul the components between the flat roof 403 and the roof rack. Therefore, The flat top plate 403 is mostly fixed by the flat top plate 403 lock. However, the flat top plate 403 is generally locked on the flat top plate 403 frame 401 by hoisting. When the flat top plate 403 is unlocked or the flat backing plate lock fails , It is necessary to drag the falling flat top plate 403 to pr...
