Summary of the invention
According to above-mentioned purpose, the utility model provides a kind of later-model being used for the latching device of passenger vehicle train tail host locking at the passenger train afterbody.In the utility model, the locking mode of train tail host is a locking-type, utilizes on the side, last vehicle of train compartment original hook as the fixed support of train tail host.
Passenger vehicle train tail host latching device of the present utility model, it is characterized in that including hook supporting plate, hook liner plate, locking lever and key, the centre portion of described hook liner plate is vertical spill, described hook supporting plate, the housing of hook liner plate by fastener and train tail host are connected and are decided to be one, through hole of formation between the spill of described hook supporting plate and described hook liner plate; One epitaxial lateral overgrowth of described hook liner plate bottom is stretched, and which is provided with the lockhole of horizontal direction, is provided with screens in the lockhole, and described locking lever is positioned at described lockhole, is with spring on the fore-end of locking lever; The shape of described key one end matches with locking lever rear end top shape; Described train tail host latching device has two states---open mode and locking state.
Of the present utility model being further characterized in that, the fore-end of described locking lever are cylindrical, and rear end part is a cydariform, and the rear end part top axle is to being triangle; Described locking lever can be in described locking hole moves and around rotational along axis; By the operation of described key, the locking lever front end is moved forward stretch out described locking hole, and rotate described locking lever, the aft end face of described cydariform part is stuck in the interior screens of locking hole, described latching device is a locking state; Or the described locking lever of backward rotation, described aft end face is unclamped from screens, the locking lever front end is return in the described locking hole under described action of the spring, and described latching device is in open mode.
Of the present utility model being further characterized in that, described train tail host latching device hangs on the hook on the side, last vehicle of train compartment, described hook is interposed between the spill of described hook supporting plate and described hook liner plate, when described latching device places locking state, the fore-end of described locking lever stretches out the below that described lockhole is blocked in described hook bent angle, and described train tail host fixing and locking is at last vehicle of train.
Of the present utility model being further characterized in that, the material of described passenger vehicle train tail host latching device is high-quality A3 steel plate and 35# structural steel, except the parts to this device carry out the surface coating processing, also the screw that is adopted between the parts is connected and make anti-loosening PROCESS FOR TREATMENT.
Because the utility model is fixed with one latching device and passenger vehicle train tail host, and the latching device lock hanging is on the hook on the side, last vehicle of train compartment, thereby need not for the passenger vehicle train tail host any connecting device to be set in addition specially at the passenger train afterbody, and the train tail host that can lock reliably, also simplified the dismounting operation simultaneously.
Train tail host fixing and locking apparatus structure advantages of simple of the present utility model, compact dimensions is connected firmly, safety and reliability height, and set out when being convenient to the operating personal operation,
With reference to the accompanying drawings, further specifically describe technical characterictic of the present utility model and advantage.
Description of drawings
Fig. 1 is the perspective view of the utility model passenger vehicle train tail host latching device;
Fig. 2 is that the A of Fig. 1 microbus train tail host latching device is to view;
Fig. 3 is the scheme of installation of the utility model passenger vehicle train tail host latching device.
Number in the figure is, 1-links up with supporting plate, and 2-links up with liner plate, 3-locking lever, 4-spring, 5-lockhole, 6-screens, 7-key, 8-train tail host housing; The 9-hook.
Specific implementation method
Referring to Fig. 1 and Fig. 2, passenger vehicle train tail host fixing and locking device of the present utility model mainly includes hook supporting plate 1, hook liner plate 2, locking lever 3 and key 4.The centre portion of hook liner plate 2 is vertical spill, and hook supporting plate 1, hook liner plate 2 be by fastener, and for example screw etc. is connected and fixed with train tail host housing 8 and is one, referring to Fig. 3.Form a through hole between the spill of hook supporting plate 1 and hook liner plate 2.
One epitaxial lateral overgrowth of hook liner plate 2 bottoms is stretched, and which is provided with the lockhole 5 of horizontal direction.Be provided with screens 6 in the lockhole, locking lever 3 is positioned at lockhole 5, and the front end of locking lever 3 is cylindrical, is with spring 4 on it.The rear end of locking lever 3 is a cydariform, and locking lever 3 can be in locking hole moves forward and backward and around rotational along axis.One end of key 7 is a sleeve-like, and hole shape matches with locking lever 3 outer end top shape in it.
Further describe the locking of the utility model train tail host latching device and the operating process of opening below.
To link up with supporting plate 1 by fastener captives joint with train tail host housing 8 with hook liner plate 2; The train tail host latching device is hung on the hook 9 on the side, last vehicle of train compartment, and hook 9 is interposed between hook supporting plate 1 and the hook liner plate 2.Key 7 is inserted on the triangle axle at the top, locking lever 3 rear end in the lockhole 5 of hook liner plates 2 one sides, and promote locking lever 3 and move forward, length of spring compressed arrives chucking position 6 approximately when the key bar end face submerges lockhole.Discharge thrust after locking lever 3 is rotated about 90 ° this moment, locking lever 3 chucking that rebounds automatically, the front end of locking lever 3 stretches out the about 20 centimetres distance of locking hole, be blocked in the below of hook bent angle, make train tail host not move up and down, so just with the train tail host kayser on hook, will train tail host can extract key after the locking.
The unlatching of train tail host latching device is opposite with the process of locking, insert on the triangle axle at the top, locking lever 3 rear end in the lockhole 5 of linking up with liner plate 2 one sides with key 7, about 90 ° of contrarotation, making locking lever 3 break away from screens unclamps from lockhole 5, the spring return is simultaneously with locking lever 3 and key 7 past rollbacks.Locking lever 3 is return in the lockhole 5, and the train tail host latching device just is in open mode like this, unclamps with train hook 9, can unload train tail host easily.
Although above the specific embodiment of the present utility model is described, but this only is exemplary, those skilled in the art can figure out: in claims institute restricted portion, multiple other embodiment can also be arranged, and all based on the implementation method of design philosophy of the present invention all within the scope of the invention.
