Detailed Embodiments

[0022] The utility model discloses a vehicle-mounted anti-leakage component, which is described in conjunction with a preferred embodiment (embodiment 1) and with reference to the accompanying drawings. Figures 1 to 8 , the specific implementation methods of the utility model are further described.

[0023] See attached figure Figures 1 to 8 , Figure 1 , Figure 3 , Figure 5 and Figure 7 The vehicle-mounted anti-leakage component of Embodiment 1 is shown in different viewing angles. Figure 2 , Figure 4 , Figure 6 and Figure 8 The vehicle-mounted anti-liquid leakage component of Example 2 is shown from different perspectives.

[0024] Example 1.

[0025] Preferably, the vehicle-mounted anti-leakage component is externally connected to the vehicle-mounted pipeline 400, and the vehicle-mounted anti-leakage component includes:

[0026] The check piece 100 includes a check piece cover 110 and a check piece body 120 built in the check piece cover 110, and the check piece body 120 and the check piece cover 110 are integrally formed;

[0027] The stopper 200 includes a stopper body 210 and a stopper main body 220, the stopper main body 210 is fixedly connected to the stopper main body 220, the stopper main body 220 is located on the side of the stopper body 210 facing the check member main body 120, the stopper main body 220 is connected to the check member main body 120, the stopper main body 220 is elastically connected to the check member main body 120, and the stopper main body 210 is screwed to the vehicle pipeline 400; when the end (open end, the same below) of the vehicle pipeline 400 needs to be temporarily closed, it is only necessary to screw the stopper 200 to the end of the vehicle pipeline 400 in turn, and then connect the check member 100 to the stopper 200, even if hydraulic oil and other liquids are still passed into the vehicle pipeline 400, no leakage will occur.

[0028] It should be noted that the reason why the stopper 200 and the check piece 100 are designed independently is mainly because the liquid pressure at the end of the vehicle pipeline 400 cannot be kept constant and may fluctuate; when the pressure at the end of the vehicle pipeline 400 is relatively high, the liquid flowing into the end of the vehicle pipeline 400 first interacts with the stopper body 210, and then interacts with the stopper body 220 and the check piece body 120, thereby expanding the force area in order to disperse the force and further curb leakage.

[0029] The end of the vehicle-mounted pipeline 400 is provided with a pipeline thread 410, so that the vehicle-mounted pipeline 400 and the stopper body 210 form a threaded fit for screw connection.

[0030] Among them, the vehicle-mounted anti-leakage liquid component further includes a sealing ring 300, and the sealing ring 300 is located between the stopper body 210 and the end of the vehicle-mounted pipeline 400.

[0031] Among them, the stopper body 220 is made of an elastic material.

[0032] Among them, the check valve body 120 is provided with an annular portion 121, the inner surface of the annular portion 121 is provided with an annular portion thread 123, and the outer surface of the annular portion 121 is provided with a plurality of reinforcing ribs 122; the stopper body 220 is provided with an elastic telescopic portion 221, and the outer surface of the elastic telescopic portion 221 is provided with a telescopic portion thread 222; so that the annular portion thread 123 and the telescopic portion thread 222 form a threaded fit for elastic connection.

[0033] Among them, the inner edge of the bottom of the stopper body 210 is provided with a plurality of positioning blocks 211, and the positioning blocks 211 are integrally formed with the stopper body 210; the cross section of the positioning blocks 211 is triangular, and the positioning blocks 211 are sequentially arranged along the inner edge of the bottom of the stopper body 210 to reduce the possibility of unplanned reverse rotation, thereby causing leakage.

[0034] Embodiment 2.

[0035] The technical solution of Embodiment 2 is the same as that of Embodiment 1. It should be noted that, for Embodiment 2, the Figure 2 , Figure 4 , Figure 6 and Figure 8 show the vehicle-mounted anti-leakage liquid component in a combined structure state. In contrast, for Embodiment 1, the Figure 1 , Figure 3 , Figure 5 and Figure 7 show the vehicle-mounted anti-leakage liquid component in an exploded structure state.

[0036] It is worth mentioning that the technical features such as the selection of the sealing ring involved in the patent application of the present utility model should be regarded as the prior art.
