DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The utility model discloses a U shield with a joint waterproof protection structure, such as Figure 1 As shown, it includes a main body 1 and a cap body 2 , a connector 3 is fixedly mounted on one side of the main body 1 , and the cap body 2 can cover the outer surface of the connector 3 .

[0022] Fixed sleeves 4 are fixedly installed on both sides of the outer surface of the main body 1, first slide bars 5 are fixedly installed on both sides of the outer surface of the cap body 2, and second slide bars 6 are fixedly installed on both sides of the outer surface of the main body 1. When the cap body 2 is connected to the main body 1, the first slide bar 5 will contact the second slide bar 6.

[0023] Fixed grooves 7 are provided on both sides of the outer surfaces of the main body 1 and the cap body 2, and limiting holes 8 are provided on both sides of the inner parts of the four fixed grooves 7. A sealing sleeve 9 is movably connected to the outer surface of the second slide rod 6, and the sealing sleeve 9 can move along the second slide rod 6. When the first slide rod 5 contacts the second slide rod 6, the sealing sleeve 9 can move to the outer surface of the first slide rod 5.

[0024] like Figure 2 As shown, a sealing rubber ring 907 is fixedly installed inside the sealing sleeve 9, and the sealing rubber ring 907 can seal the gap between the main body 1 and the cap body 2 to prevent external moisture from entering from the connection between the main body 1 and the cap body 2.

[0025] Movable frames 901 are fixedly mounted on both sides of the outer surface of the sealing sleeve 9 , and rotating plates 902 are movably mounted inside the two movable frames 901 . The rotating plates 902 can rotate inside the movable frames 901 .

[0026] Fixed blocks 903 are fixedly installed on both sides of the two rotating plates 902, telescopic holes 904 are provided on both sides of the four fixed blocks 903, first springs 905 are fixedly installed inside the eight telescopic holes 904, and limiting heads 906 are fixedly installed at one end of the eight first springs 905, which can squeeze the first springs 905.

[0027] When the sealing sleeve 9 moves to a suitable position, the rotating plate 902 can be rotated, and the fixing block 903 can be inserted into the fixing groove 7. During this process, the limit head 906 will be retracted into the telescopic hole 904 due to the inner wall of the fixing groove 7. When the fixing block 903 is fully inserted, the limit head 906 can be pushed into the limit hole 8 by the influence of the squeezed first spring 905 to prevent the sealing sleeve 9 from continuing to move.

[0028] The end of the limiting head 906 away from the first spring 905 is hemispherical, and the hemispherical limiting head 906 is relatively smooth, so the staff only needs to use a greater force to pull the fixing block 903 to pull it out of the fixing groove 7.

[0029] like Figure 3 As shown, a second spring 401 is fixedly installed inside the fixing sleeve 4, and a fixing rod 402 is fixedly installed at one end of the second spring 401. The fixing rod 402 can move inside the fixing sleeve 4, and a hanging ring 403 is movably installed at one end of the fixing rod 402 away from the second spring 401. When the cap body 2 is connected to the main body 1, the hanging ring 403 can be hung in the hook 201 to prevent the cap body 2 from falling.

[0030] like Figure 4-5 As shown, the cap body 2 includes a sealing cover 204 and a moisture-absorbing cotton block 203 , and an isolation cavity 202 is provided on one side of the cap body 2 , and the moisture-absorbing cotton block 203 can be placed in the isolation cavity 202 .

[0031] There are mounting holes 205 on both sides of the sealing cover 204, and two connecting holes 206 are provided on one side of the cap body 2. Hooks 201 are fixedly installed on both sides of the outer surface of the cap body 2. When one side of the sealing cover 204 is inserted into the isolation chamber 202, the two mounting holes 205 will coincide with the two connecting holes 206. Then, the external bolts are inserted to complete the installation of the sealing cover 204, so as to facilitate the replacement of the moisture-absorbing cotton block 203 placed in the isolation chamber 202. A protective gasket 207 is fixedly installed inside the cap body 2.

[0032] The working principle of the utility model is as follows: after the U shield is used, the user holds the main body 1 and inserts the connector 3 into the cap body 2 to make the main body 1 contact the cap body 2, and then pulls the two hanging rings 403 to hang them in the hooks 201 to prevent the cap body 2 from falling off, and then moves the sealing sleeve 9 to move it along the second slide bar 6 to the first slide bar 5, so that the sealing rubber ring 907 can seal the connection between the main body 1 and the cap body 2 to prevent external moisture from entering through the connection between the main body 1 and the cap body 2, and then rotates The two rotating plates 902 are used to insert the fixing block 903 into the fixing groove 7. During this process, the limit head 906 will be retracted into the telescopic hole 904 due to the inner wall of the fixing groove 7. When the fixing block 903 is fully inserted, the limit head 906 can be pushed into the limit hole 8 under the influence of the squeezed first spring 905 to prevent the sealing sleeve 9 from continuing to move. When the sealing sleeve 9 needs to be moved again, the staff only needs to use a greater force to pull the fixing block 903 to pull it out of the fixing groove 7 to move the sealing sleeve 9.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
