Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 - Figure 4 As shown, the present utility model is a speed reducer and its oil leakage prevention port, including a plug 1 installed in the oil leakage prevention port. The plug 1 includes a connecting block 101. The lower surface of the connecting block 101 is provided with a mounting block 102. The upper surface of the connecting block 101 is provided with a first mounting groove 103. One end of the first mounting groove 103 extends into the interior of the mounting block 102. A cover body 104 is fitted and installed in the first mounting groove 103. A limit component 2 is arranged in the first mounting groove 103;

[0027] By setting the limit component 2 to replace the threaded connection method, the occurrence of thread wear is avoided, the tightness of the connection between the plug 1 and the oil port is ensured, and at the same time, the service life and use effect of the plug 1 can be extended;

[0028] The limiting component 2 includes a hand-tightening bolt 201. An installation hole is formed in the middle of the cover body 104. The hand-tightening bolt 201 is threadedly connected inside the installation hole. A slider 202 is arranged inside the first installation groove 103. The hand-tightening bolt 201 is installed on the upper surface of the slider 202. An inclined surface is formed on the outer surface of the slider 202. A placement groove 105 is formed on the outer surface of the connection block 101. A second installation groove 106 is formed on the inner surface of the placement groove 105. A spring 203 is installed inside the second installation groove 106. The other end of the spring 203 is installed with a limiting block 204. A sliding rod 205 is installed on the outer surface of the limiting block 204. One end of the sliding rod 205 extends into the first installation groove 103. The outer surface of the sliding rod 205 abuts against the outer surface of the slider 202;

[0029] Baffles 206 are provided at both ends of the slider 202;

[0030] A sealing ring 3 is installed on the lower surface of the connection block 101;

[0031] By providing the sealing ring 3, the sealing performance between the plug 1 and the oil port can be further improved, preventing engine oil from leaking out from the connection between the plug 1 and the oil port, and achieving a good anti-leakage effect;

[0032] Corrosion-resistant coatings are applied to the outer surfaces of both the plug 1 and the limiting component 2;

[0033] By applying the corrosion-resistant coatings to the outer surfaces of both the plug 1 and the limiting component 2, the corrosion resistance of the plug 1 and the limiting component 2 can be increased, and their service life can be prolonged;

[0034] A speed reducer includes an anti-oil leakage port. A limiting groove is formed in the inner wall of the speed reducer oil port, and a limiting block 204 is fitted and installed inside the limiting groove.

[0035] During use, first place the plug 1 directly above the oil port of the speed reducer. After placement, by pushing down the connecting block 101, the mounting block 102 gradually slides into the interior of the oil port. When the outer surface of the connecting block 101 abuts against the outer surface of the speed reducer, at this time, the mounting block 102 is fitted and installed in the oil port. At the same time, the limiting block 204 is located on one side of the limiting groove. By rotating the hand-tightening bolt 201 clockwise, the hand-tightening bolt 201 moves axially downward with the mounting hole as the center, causing the hand-tightening bolt 201 to push the slider 202 downward in the first mounting groove 103. During the downward movement of the slider 202, it will push the sliding rod 205 to move outward, causing the limiting block 204 to gradually move into the limiting groove, and at the same time, the spring 203 is gradually stretched. When the limiting block 204 is fitted and installed in the limiting groove, at this time, the plug 1 is fixedly installed inside the oil port. When it is necessary to remove the plug 1, by rotating the hand-tightening bolt 201 counterclockwise, the hand-tightening bolt 201 moves axially upward with the mounting hole as the center, causing the hand-tightening bolt 201 to drive the slider 202 to move upward in the first mounting groove 103. During the upward movement of the slider 202, the spring 203 will gradually cancel the stretched state and drive the limiting block 204 to move into the placement groove 105. At the same time, the slider 202 moves into the first mounting groove 103. When the spring 203 is fully restored, the limiting block 204 is fitted and installed in the placement groove 105. At this time, the plug 1 can be pulled upward to remove the plug 1 from the oil port. By setting the limiting component 2 to replace the threaded connection method, the occurrence of thread wear is avoided, ensuring the tightness of the connection between the plug 1 and the oil port. At the same time, it can also extend the service life and use effect of the plug 1. During use, by setting the sealing ring 3, the sealing performance between the plug 1 and the oil port can be further increased, preventing the leakage of engine oil from the connection between the plug 1 and the oil port, and achieving a good anti-leakage effect.
