[0030] like Figures 1 to 5As shown, a drive bridge cover plate in one embodiment of the present utility model includes a cover plate body 1 and a vent plug body 2.

[0031] The cover plate body 1 is connected to a connecting seat 101 , which is used to install the vent plug body 2 so that the vent plug body 2 can be used to relieve pressure on the drive axle to ensure that the drive axle can operate safely and stably.

[0032] In addition, a fixing groove 102 and a pair of insertion grooves 103 are provided in the connecting seat 101, and the insertion groove 103 is connected to the fixing groove 102. The connecting ear 201 can enter the fixing groove 102 through the insertion groove 103, thereby achieving the installation and fixation of the vent plug body 2.

[0033] Specifically, a receiving groove 104 is provided in the connecting seat 101 . The receiving groove 104 is communicated with the fixing groove 102 . The receiving groove 104 is used to receive the spring 105 .

[0034] like Figures 1 to 5 As shown, a tightening mechanism is installed in the connecting seat 101, which is used to press against the connecting ear 201 so that the connecting ear 201 can contact the upper wall of the fixing groove 102, thereby fixing the vent plug body 2 on the connecting seat 101.

[0035] The tightening mechanism includes a spring 105, which is disposed within the receiving groove 104. The spring 105 surrounds the vent plug body 2 and contacts the connecting ear 201. When the connecting ear 201 is disposed within the fixing groove 102 through the insertion groove 103, the spring 105 exerts an elastic force on the connecting ear 201, allowing the connecting ear 201 to contact the top wall of the fixing groove 102, thereby securing the connecting ear 201 within the connecting seat 101, ensuring that the vent plug body 2 is securely fixed to the connecting seat 101. This simplifies the connection structure of the vent plug body 2 to the cover body 1, facilitates quick removal of the vent plug body 2 by the user, and improves the maintenance efficiency of the vent plug body 2.

[0036] In addition, a pair of engaging posts 106 are fixedly connected to the top wall of the fixing groove 102, and the connecting ear 201 is provided with an engaging groove that matches the engaging posts 106. When the connecting ear 201 is arranged in the fixing groove 102, the engaging posts 106 can be engaged in the engaging groove, thereby further fixing the connecting ear 201, so that the vent plug body 2 can be firmly fixed to the connecting base 101.

[0037] Preferably, the angle between the insertion slot 103 and the snap-fit ​​column 106 is 90°, and the connecting ear 201 can enter the fixing slot 102 from the insertion slot 103, and then snap-fit ​​into the snap-fit ​​slot through the snap-fit ​​column 106, so that the connecting ear 201 can be firmly fixed.

[0038] like Figures 1 to 5 As shown, the vent plug body 2 is inserted into the connecting seat 101 , and the vent plug body 2 is used to relieve pressure on the drive axle to balance the pressure inside the drive axle.

[0039] A pair of connecting ears 201 are fixedly connected to the side walls of the vent plug body 2. The connecting ears 201 correspond to the pair of insertion slots 103, and both connecting ears 201 are disposed within the fixing slots 102, with the abutting mechanism in contact with the connecting ears 201. By inserting the connecting ears 201 into the fixing slots 102, the vent plug body 2 is installed and secured. This simplifies the connection structure of the vent plug body 2 to the cover body 1 and facilitates quick removal of the vent plug body 2, thereby improving maintenance efficiency of the vent plug body 2.

[0040] Preferably, the vent plug body 2 is made of hard metal, and the angle between the pair of connecting ears 201 is 180°.

[0041] In addition, a pair of limit plates 202 are fixedly connected to the connecting ear 201, and a avoidance groove matching the limit plate 202 is provided in the connecting seat 101. The limit plate 202 is arranged on the inner side of the spring 105. The limit plate 202 is used to fix the spring 105 so that the spring 105 is not easily deflected.

[0042] Specifically, a mounting groove 203 and an air outlet groove 204 are provided in the vent plug body 2. A connecting pipe is installed in the vent plug body 2. The mounting groove 203 is connected to the air outlet groove 204 through the connecting pipe, and gas can enter the air outlet groove 204 through the connecting pipe.

[0043] In addition, a vent pipe 205 is connected to the vent plug body 2. The vent pipe 205 is connected to the connecting pipe, and one end of the vent pipe 205 is disposed within the mounting groove 203. A plurality of air outlet holes 206 are provided on the sidewall of the vent plug body 2. The air outlet groove 204 communicates with the outside world through the air outlet holes 206. The provision of the plurality of air outlet holes 206 allows the exhaust of gas within the drive axle and also prevents rainwater from entering the air outlet groove 204.

[0044] During specific use, when the vent plug body 2 needs to be installed, the connecting ear 201 is inserted into the fixing groove 102 through the insertion groove 103, and the vent plug body 2 is pressed to compress the spring 105. The vent plug body 2 and the connecting ear 201 are rotated, and the connecting ear 201 can rotate within the fixing groove 102. When the connecting ear 201 rotates to one side of the fixing groove 102, the vent plug body 2 is no longer pressed, and the connecting ear 201 contacts the upper wall of the fixing groove 102 under the action of the spring 105. At this time, the engaging column 106 can engage with the engaging groove on the connecting ear 201, thereby achieving the installation and fixation of the vent plug body 2.

[0045] Through the arrangement of the above-mentioned structure, the present application can simplify the connection structure of the vent plug body 2 on the cover plate body 1, making it convenient for users to quickly disassemble the vent plug body 2, thereby improving the maintenance efficiency of the vent plug body 2.
