Abstract

The utility model discloses a can waterproof checking cylinder shield, checking cylinder shield fixed connection on the protecgulum of checking cylinder, its the edge of checking cylinder shield, the skirt pendulum that its axial of edge was provided with outside extension. The utility model discloses an edge's shaping at current checking cylinder shield has skirt pendulum structure, utilizes the skirt pendulum to keep off the rainwater that flows down along the shield outside the gas passage of shield opening, keeps apart gas passage with rainwater trickling circuit, and when preventing effectively that the checking cylinder from alleviating, the negative pressure that the rainwater formed in by the checking cylinder inhales in the cylinder body to play waterproof effect, improve the life of checking cylinder, ensure driving safety.

Description

A kind of waterproof checking cylinder dust cap

Technical field

This utility model belongs to car braking cylinder technology field, particularly to a kind of waterproof checking cylinder dust cap.

Background technology

Railway vehicle braking cylinder is typically mounted at vehicle bottom, and car body can block rainwater and enter cylinder body, such as open-top car, box car etc..But some vehicles, such as flatcar, tank car, cementing truck etc., car body blocks checking cylinder the most completely, and rainwater is easy to pour checking cylinder, enters checking cylinder.

As shown in Figure 1, existing goods train vehicle checking cylinder dust cap only has dust reduction capability, not having water-proof function, checking cylinder is once drenched with rain in rainwater sky, during alleviation, the top of dirt catcher composition 4 can form negative pressure, rainwater can be along its inwall at the C of checking cylinder dust cap 1, and the filter dirt felt pan through dirt catcher composition 4 is drawn into cylinder body, thus causes the pollution within checking cylinder and corrosion, it is substantially reduced the service life of checking cylinder, affects traffic safety.

Utility model content

Goal of the invention of the present utility model is: for the problem of above-mentioned existence, it is provided that one can effectively prevent rainwater from entering in checking cylinder, thus improves checking cylinder service life, it is ensured that the waterproof checking cylinder dust cap of traffic safety.

The technical solution of the utility model is achieved in that a kind of waterproof checking cylinder dust cap, described checking cylinder dust cap is fixedly connected on the protecgulum of checking cylinder, it is characterised in that: described checking cylinder dust cap edge, axially arranged have outward extending train of dress along it.

Waterproof checking cylinder dust cap described in the utility model, its described train of dress is overall in toroidal.

Waterproof checking cylinder dust cap described in the utility model, its described train of dress and checking cylinder dust cap are molded as one structure.

This utility model is by forming skirt structure in the edge of existing checking cylinder dust cap, train of dress is utilized to be kept off outside the gas passage opening of dust cap by the rainwater flowed down along dust cap, by gas passage and rainwater trickling circuit isolation, when effectively preventing checking cylinder from alleviating, in the negative pressure suction cylinder body that rainwater is formed in being braked cylinder, thus play waterproof action, improve the service life of checking cylinder, it is ensured that traffic safety.

Accompanying drawing explanation

Fig. 1 is the use state diagram of existing checking cylinder dust cap.

Fig. 2 is structural representation of the present utility model.

Fig. 3 is use state diagram of the present utility model.

Fig. 4 is the close-up schematic view of checking cylinder dust cap in Fig. 3.

Labelling in figure: 1 is checking cylinder dust cap, 2 is protecgulum, and 3 is train of dress, and 4 form for dirt catcher.

Detailed description of the invention

Below in conjunction with the accompanying drawings, this utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.

Such as Fig. 2, shown in 3 and 4, a kind of waterproof checking cylinder dust cap, described checking cylinder dust cap 1 is fixedly connected on the protecgulum 2 of checking cylinder, described checking cylinder dust cap 1 edge, axially arranged have outward extending train of dress 3 along it, described train of dress 3 is molded as one structure with checking cylinder dust cap 1, and described train of dress 3 entirety is toroidal.

As shown in Figure 4, when rainwater flows down along checking cylinder dust cap, owing to there being the dash effect of train of dress on dust cap, rainwater falls directed along at train of dress, thus by gas passage and rainwater trickling circuit isolation, plays waterproof action, when checking cylinder is alleviated, form negative pressure above the filter dirt felt pan of dirt catcher composition, but owing to rainwater does not arrives at the C of dust cap under train of dress barrier effect, the most also would not be inhaled in cylinder body.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
