The coolant may leak during the process of being input into the box body through the coolant inlet pipe, which is easy to cause waste of coolant. Utility Model Content

[0004] The utility model aims to provide a sealing ring for an engine oil cooler, which solves the existing problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a sealing ring for an engine oil cooler, comprising a box body, wherein two sides of the box body are respectively penetrated and fixedly connected with an oil inlet pipe and an oil outlet pipe, a bracket is fixedly connected inside the box body, a cooling pipe is fixedly connected inside the box body through the bracket, one end of the cooling pipe is fixedly connected with a cooling introduction pipe, the other end of the cooling pipe penetrates and is fixedly connected with the side surface of the box body, a sealing ring mechanism is arranged on the side surface of the box body, the sealing ring mechanism comprises an air chamber, a sealing ring and a fixing plate, the air chamber is fixedly connected to the side surface of the box body through a connecting plate, an internal piston of the air chamber is slidably connected with a piston rod, the bottom of the piston rod is fixedly connected with a movable plate, the top of the air chamber penetrates and is fixedly connected with an air delivery pipe, the sealing ring is fixedly connected to the inside of the cooling introduction pipe, one end of the air delivery pipe away from the air chamber is penetrated and fixedly connected with the sealing ring, the fixing plate is fixedly connected to the side surface of the box body, the top of the fixing plate is rotatably connected with a threaded rod, the movable plate is threadedly connected with the threaded rod, the side surface of the threaded rod is fixedly connected with a turning handle, and the top of the turning handle is provided with a locking mechanism.

[0007] Furthermore, the inner diameter of the cooling inlet pipe is the same as the inner diameter of the cooling pipe, and the coolant can be introduced into the cooling pipe through the cooling inlet pipe.

[0008] Furthermore, the sealing ring is made of rubber, and the outer surface of the sealing ring fits the inner wall of the cooling inlet pipe. The sealing ring made of rubber has a certain elasticity and can be used for sealing between pipes.

[0009] Furthermore, the interior of the sealing ring is hollow, and the sealing ring is in a contracted state in an initial state, and will expand when the air pressure in the sealing ring increases.

[0010] Furthermore, the locking mechanism includes a sliding plate, a vertical rod and a circular ring, the sliding plate is slidably connected to the top of the turning handle, the vertical rod passes through and is slidably connected to the top of the turning handle, the top of the vertical rod is fixedly connected to a limiting block, the bottom of the vertical rod is fixedly connected to a counterweight block, and the circular ring is fixedly connected to the top of the fixed plate.

[0011] Furthermore, the bottom of the limit block is initially in conflict with the top of the sliding plate, and the gravity of the counterweight block is greater than the friction between the vertical rod and the handlebar. At the beginning, the limit block prevents the vertical rod from moving downward.

[0014] The utility model is provided with a sealing ring mechanism, so that when the coolant pipe is inserted into the cooling inlet pipe and the coolant is input into the cooling pipe, the threaded rod can be rotated by the handle. At this time, the sealing ring will expand through the cooperation of the piston rod, the air chamber, the air supply pipe and other components to seal the joint between the coolant pipe and the cooling inlet pipe, so as to prevent the coolant from leaking and wasting. The subsequent reverse rotation of the threaded rod will cause the sealing ring to shrink again to facilitate the removal of the coolant pipe.

[0015] The utility model is provided with a locking mechanism, so that when the threaded rod is rotated to expand the sealing ring for sealing, the sliding plate can be slid to the left. At this time, the cooperation of the counterweight block, the vertical rod, the circular ring and other components will make the turning handle and the threaded rod unable to rotate any more, thereby preventing the threaded rod from rotating due to accidental touch and causing the sealing ring to shrink.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6The utility model is a sealing ring for an engine oil cooler, comprising a box body 1, two sides of the box body 1 are respectively penetrated and fixedly connected with an oil inlet pipe 2 and an oil outlet pipe 3, the inside of the box body 1 is fixedly connected with a bracket 4, the inside of the box body 1 is fixedly connected with a cooling pipe 5 through the bracket 4, one end of the cooling pipe 5 is fixedly connected with a cooling introduction pipe 6, the other end of the cooling pipe 5 penetrates and is fixedly connected to the side of the box body 1, and a sealing ring mechanism 7 is provided on the side of the box body 1, the sealing ring mechanism 7 comprises an air chamber 71, a sealing ring 75 and a fixing plate 76, and the air chamber 71 is fixedly connected to the side of the box body 1 through a connecting plate The internal piston of the gas bin 71 is slidably connected to the piston rod 72, and the bottom of the piston rod 72 is fixedly connected to a movable plate 73. The top of the gas bin 71 passes through and is fixedly connected to an air pipe 74. The sealing ring 75 is fixedly connected to the inside of the cooling inlet pipe 6. The end of the air pipe 74 away from the gas bin 71 passes through and is fixedly connected to the sealing ring 75. The fixed plate 76 is fixedly connected to the side of the box body 1. The top of the fixed plate 76 is rotatably connected to a threaded rod 77. The movable plate 73 is threadedly connected to the threaded rod 77. The side of the threaded rod 77 is fixedly connected to a turning handle 78, and a locking mechanism 8 is provided on the top of the turning handle 78.

[0028] The inner diameter of the cooling introduction pipe 6 is the same as the inner diameter of the cooling pipe 5 , and the cooling liquid can be introduced into the cooling pipe 5 through the cooling introduction pipe 6 .

[0029] The sealing ring 75 is made of rubber, and the outer surface of the sealing ring 75 fits the inner wall of the cooling inlet pipe 6. The sealing ring 75 made of rubber has a certain elasticity and can be used for sealing between pipes.

[0030] The interior of the sealing ring 75 is hollow, and the sealing ring 75 is initially in a contracted state. When the air pressure in the sealing ring 75 increases, the sealing ring 75 will expand.

[0031] The locking mechanism 8 includes a sliding plate 81, a vertical rod 82 and a ring 85. The sliding plate 81 is slidably connected to the top of the turning handle 78. The vertical rod 82 passes through and is slidably connected to the top of the turning handle 78. The top of the vertical rod 82 is fixedly connected to a limiting block 83. The bottom of the vertical rod 82 is fixedly connected to a counterweight block 84. The ring 85 is fixedly connected to the top of the fixed plate 76.

[0032] The bottom of the limit block 83 is initially in conflict with the top of the sliding plate 81, and the gravity of the counterweight block 84 is greater than the friction between the vertical rod 82 and the handle 78. At the beginning, the limit block 83 prevents the vertical rod 82 from moving downward. After the sliding plate 81 moves to the right, the gravity of the counterweight block 84 will drive the vertical rod 82 to move downward.

[0033] The bottom of the counterweight 84 and the top of the ring 85 are both provided with teeth. When the counterweight 84 moves downward, it will contact the ring 85. At this time, the teeth at the bottom of the counterweight 84 will mesh with the teeth at the top of the ring 85, so that the handle 78 cannot drive the threaded rod 77 to rotate.

[0034] A specific application of the present embodiment is as follows: the engine oil is input through the oil inlet pipe 2, the engine oil is discharged through the oil outlet pipe 3, the coolant pipe is inserted into the cooling introduction pipe 6, and the coolant is input into the cooling pipe 5. At this time, the threaded rod 77 can be rotated by the turning handle 78. The rotation of the threaded rod 77 will cause the movable plate 73 to move upward. The upward movement of the movable plate 73 will drive the piston rod 72 to move upward. The upward movement of the piston rod 72 will squeeze the gas in the air chamber 71 so that it enters the sealing ring 75 through the air delivery pipe 74. At this time, the air pressure in the sealing ring 75 increases and expands. The expansion of the sealing ring 75 will seal the joint between the coolant pipe and the cooling introduction pipe 6 to prevent the coolant from leaking and wasting. When the coolant pipe needs to be pulled out, the turning handle 78 and the threaded rod 77 are rotated in the opposite direction. When the piston rod 72 moves downward, the movable plate 73 will drive the piston rod 72 to move downward. The downward movement of the piston rod 72 will form a negative pressure in the gas chamber 71, thereby sucking the gas in the sealing ring 75 through the gas supply pipe 74. At this time, the sealing ring 75 contracts to facilitate the removal of the coolant pipe. After the sealing ring 75 is expanded by rotating the threaded rod 77 to complete the sealing work, the sliding plate 81 can be slid to the left to make it leave the vertical rod 82. At this time, the gravity of the counterweight block 84 will drive the vertical rod 82 to move downward. The counterweight block 84 moves downward and contacts with the ring 85. At this time, the teeth at the bottom of the counterweight block 84 will mesh with the teeth at the top of the ring 85, so that the turning handle 78 cannot drive the threaded rod 77 to rotate, thereby preventing the threaded rod 77 from rotating due to accidental touch, causing the sealing ring 75 to shrink.
