[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-5 A sealing joint for engineering machinery includes a joint body 100, a connecting pipe 200, and a fixing block 201. The connecting pipe 200 matches the joint body 100, and the fixing blocks 201 on both sides are fixedly connected to the two sides of the outer wall of the connecting pipe 200. A fixing component is provided inside the joint body 100.

[0026] Among them, the fixing component includes a connecting frame 202, and the connecting frames 202 on both sides are fixedly connected to the two sides of the outer wall of the joint body 100. The interiors of the connecting frames 202 on both sides are movably connected with fixing plates 203. Both sides of the interior of the joint body 100 are provided with fixing grooves 204. The fixing plates 203 on both sides match the fixing grooves 204 on both sides. The interiors of the connecting frames 202 on both sides are movably connected with positioning rods 205. The outer walls of the positioning rods 205 on both sides are sleeved with springs 206. The interiors of the fixing plates 203 on both sides are provided with positioning holes 207. The fixing blocks 201 on both sides are in a fitting relationship with the fixing plates 203 on both sides. By inserting the connecting pipe 200 into the interior of the joint body 100 and rotating it, the fixing blocks 201 on both sides of the outer wall of the connecting pipe 200 are rotated into the interiors of the fixing grooves 204 on both sides. At this time, by pushing the two side fixing plates 203, they push the two side fixing blocks 201 to move into the inside of the two side fixing grooves 204. When the two side fixing plates 203 are pushed to the appropriate position, by pulling the two side positioning rods 205 and cooperating with the two side springs 206, they enter the corresponding positioning holes 207, so that the fixing plates 203 can be fixed, so that the two side fixing blocks 201 cannot move, thereby completing the fixed sealing work between the joint body 100 and the connecting pipe 200. The two side springs 206 can always make the positioning rods 205 inside the positioning holes 207, ensuring that the connection between the connecting pipe 200 and the joint body 100 is more firm and the sealing is better. This connection method is simple and convenient for the staff to use, so that the staff can complete the fixed connection installation without the help of other tools.

[0027] The outer walls of the fixing plates 203 on both sides and the outer walls of the positioning rods 205 on both sides are fixedly connected with anti-sliding blocks, so that the fixing plates 203 on both sides and the positioning rods 205 on both sides can be moved more easily.

[0028] One end of the fixing plates 203 on both sides is fixedly connected to the limiting block 208 , thereby preventing the fixing plates 203 on both sides from being separated from the interior of the connecting frames 202 on both sides.

[0029] A sealing sleeve 209 is fixedly connected to the inner wall of the joint body 100 . The sealing sleeve 209 matches the connecting pipe 200 , thereby increasing the sealing performance of the joint body 100 .

[0030] The connecting frames 202 on both sides and the fixing plates 203 on both sides are arc-shaped. The curvature of the fixing plates 203 on both sides matches the curvature of the outer wall of the connector body 100 , so that the fixing plates 203 on both sides can move more smoothly.

[0031] The outer walls of the positioning rods 205 on both sides are fixedly connected with connecting rings, and the connecting rings on both sides are located on one side of the springs 206 on both sides, so that the reverse thrust of the springs 206 on both sides can be more easily received through the connecting rings on both sides.

[0032] The fixing blocks 201 on both sides and the fixing plates 203 on both sides are provided in two groups, so that the connection between the joint body 100 and the connecting pipe 200 can be more firmly established.

[0033] Working principle: By inserting the connecting tube 200 into the interior of the connector body 100 and rotating it, the fixing blocks 201 on both sides of the outer wall of the connecting tube 200 rotate into the interior of the fixing grooves 204 on both sides. At this time, by pushing the fixing plates 203 on both sides, the fixing blocks 201 on both sides are pushed to move into the interior of the fixing grooves 204 on both sides. When the fixing plates 203 on both sides are pushed to the appropriate positions, by pulling the positioning rods 205 on both sides and cooperating with the springs 206 on both sides, they are made to enter the corresponding positioning holes 207, so that the fixing plates 203 can be fixed, so that the fixing blocks 201 on both sides are free The method is to move, thereby completing the fixed sealing work between the joint body 100 and the connecting pipe 200. The positioning rod 205 can always be placed inside the positioning hole 207 through the springs 206 on both sides, ensuring that the connection between the connecting pipe 200 and the joint body 100 is more firm and the sealing is better. This connection method is simple and convenient for the staff to use, so that the staff can complete the fixed connection installation without the aid of other tools. The inner wall of the joint body 100 is fixedly connected with a sealing sleeve 209, which matches the connecting pipe 200, thereby increasing the sealing of the joint body 100.
