Abstract
An under-car cell box anti-dropping device of a railway carriage comprises a slot limiting component which is rotationally fixed through a pin shaft, and a baffle component, wherein the improvement of the device is that: a gap is arranged at the rear end of an upper plane of the slot limiting component; the rear end of the upper plane of the baffle component extends and bends upwards; the baffle component extends on the upper plane and bends upwards. The anti-dropping device not only can keep an included angle between the baffle component and the slot limiting component between designed angles, but also can press the bending surface of the baffle component by a hand when the box door requires opening. The anti-dropping device is convenient for operation, ensures that the baffle component does not generate possible situation in original structure due to manufacturing error, practically plays a role of baffle when the cell box door is opened by error and effectively prevents the cell box door from dropping.
Description
Technical field
The utility model relates to battery box anti-drop device under the passenger train car, belongs to battery box anti-drop device technical field of structures.
Background technology
Battery box anti-drop device under the existing passenger train car, as shown in Figure 1, the grooved limiting component 1 that is fixed on the casing is one with backstopping assembly 2 through bearing pin 3 rotational fixation.Its principle is: with bearing pin 3 is the center of circle, and backstopping assembly 2 can extremely get into and grooved limiting component 1 by left-hand revolution fully, and this moment, the battery chamber door can be opened.Under the effect that does not have external force; Backstopping assembly 2 rotates counterclockwise the rear inside wall that props up the grooved fiber component until its rear end owing to self gravitation; This moment, backstopping assembly 2 was 2-4mm with the chamber door gap, played preventing to play backstop action when chamber door from opening by mistake, thereby prevented that chamber door from coming off.
But in the actual fabrication process; All there is manufacturing errors in grooved limiting component 1 with backstopping assembly 2 reason owing to processing technology when Bending Processing; Cause the pin-and-hole center to become big to the distance H of grooved limiting component 1 upper limb; When H greater than big can be when pin rotates freely to backstopping assembly 2,2 of stop parts are in free state, can't play backstop action.
Summary of the invention
The utility model technical matters to be solved is; Overcome the above-mentioned shortcoming of prior art, battery box anti-drop device under a kind of passenger train car is provided, effectively stop to lose efficacy because of errors of processing technique causes anti-drop device; Conscientiously play backstop action, simultaneously handled easily.
In order to solve above technical matters; Battery box anti-drop device under the passenger train car that the utility model provides; Composition comprises: be grooved limiting component, the backstopping assembly of one through the bearing pin rotational fixation; It is characterized in that: breach is offered in the rear end, last plane of said grooved limiting component, and the rear end, plane is extended and had a bending upwards on the said backstopping assembly.
Under this passenger train car in the battery box anti-drop device, when the plane props up grooved limiting component breach on the backstopping assembly, on the backstopping assembly on plane and the grooved limiting component angular range on plane be 35 °-45 °.
Backstopping assembly extends on last plane and upwards bending, can make not only that angle remains between the design angle between backstopping assembly and the grooved limiting component; When needs were opened chamber door, only with hand got final product to the folding surface that presses down backstopping assembly, both handled easily; And guaranteed that stop can not produce the situation that possibly occur in the original structure because of manufacturing errors.When the battery chamber door opens by mistake, play the backstop effect conscientiously, prevent that effectively the battery box chamber door from coming off.
It is thus clear that, the utility model ingenious conception, simple in structure, reliability is high and be easy to manufacture.The utility model will be widely used in field of track traffic, have good market outlook.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a battery box anti-drop device structural representation under the utility model passenger train car.
Fig. 2 is the scheme drawing that utilizes battery box anti-drop device installation wood covering under the utility model passenger train car.
The specific embodiment
Battery box anti-drop device under the passenger train car of present embodiment; As shown in Figure 1; Composition comprises: be grooved limiting component 1, the backstopping assembly 2 of one through bearing pin 3 rotational fixation; Its improvements are: breach 4 is offered in the rear end, last plane of grooved limiting component 1, and the rear end, plane is extended and had a bending 5 upwards on the backstopping assembly 2.In the present embodiment, when the plane props up the breach 4 of grooved limiting component 1 on the backstopping assembly 2, on the backstopping assembly 2 on plane and the grooved limiting component 1 angle on plane be 42 °, designing requirement gets final product between 35 °-45 °.
Backstopping assembly extends on last plane and upwards bending, can make not only that angle remains between the design angle between backstopping assembly and the grooved limiting component; When needs were opened chamber door, only with hand got final product to the folding surface that presses down backstopping assembly, both handled easily; And guaranteed that stop can not produce the situation that possibly occur in the original structure because of manufacturing errors.When the battery chamber door opens by mistake, play the backstop effect conscientiously, prevent that effectively the battery box chamber door from coming off.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
1. battery box anti-drop device under the passenger train car; Composition comprises: be grooved limiting component, the backstopping assembly of one through the bearing pin rotational fixation; It is characterized in that: breach is offered in the rear end, last plane of said grooved limiting component, and the rear end, plane is extended and had a bending upwards on the said backstopping assembly.
2. battery box anti-drop device under the passenger train car according to claim 1 is characterized in that: when the plane props up grooved limiting component breach on the backstopping assembly, on the backstopping assembly on plane and the grooved limiting component angular range on plane be 35 °-45 °.
