Abstract
Description
Technical Field
[0001] This utility model belongs to the field of multi-cylinder cylinder anti-leakage technology, and particularly relates to a multi-cylinder cylinder anti-leakage sealing structure. Background Technology
[0002] A cylinder is a cylindrical metal component that guides the piston to perform linear reciprocating motion inside the cylinder. In an engine cylinder, air expands and converts thermal energy into mechanical energy. In a compressor cylinder, gas is compressed by the piston to increase its pressure.
[0003] In common multi-cylinder cylinders, the connection between the cylinder and the air pipe is prone to loosening over prolonged use. This loosening leads to air leakage, causing unstable air pressure and fluctuations in the cylinder's thrust or pull force, resulting in inconsistent power output. Therefore, we propose a leak-proof sealing structure for multi-cylinder cylinders. Utility Model Content
[0004] The purpose of this invention is to provide a leak-proof sealing structure for multi-cylinder cylinders to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a multi-cylinder cylinder anti-leakage sealing structure, including a multi-cylinder cylinder and an electromagnetic pneumatic valve, and further including:
[0006] Two air vents are provided, both of which are fixedly installed on one side of the multi-cylinder cylinder. A sealing gasket is fixedly installed on the periphery of each air vent. An air pipe is fitted onto one end of each air vent, and a sealing gasket is fixedly installed on one end of each air pipe, which contacts the sealing gasket. A threaded cap is fitted onto the air pipe, and one end of the threaded cap extends to the periphery of the air vent. The other ends of both air pipes are fixed to an electromagnetic pneumatic valve.
[0007] A limiting component is located on a multi-cylinder cylinder and is used to limit the movement of two threaded caps.
[0008] In this technical solution, during installation, personnel can first place one end of each of the two air tubes onto one end of each of the two air vents. At this time, the second sealing gasket at one end of the air tube will contact the first sealing gasket on the air vent. Then, the threaded cap is rotated. Under the action of the threads, the threaded cap rotates and moves on the air vent. The movement of the threaded cap will drive the air tube to move, causing one end of the air tube to squeeze the air vent. At this time, the first and second sealing gaskets will deform, thereby sealing the air vent and the air tube. At the same time, with the anti-slip effect of several anti-slip textures, the friction force of personnel rotating the threaded cap is increased, making the threaded cap easier to rotate.
[0009] Subsequently, personnel can use the limiting component to limit the threaded cap, preventing it from rotating and ensuring a tighter connection between the vent and the air pipe, thus effectively preventing air leakage.
[0010] In the above technical solution, the limiting component further includes:
[0011] Two limiting rods are fixedly installed on one side of the multi-cylinder cylinder and on one side of the two air vents. Clamping plates are slidably installed on the limiting rods and on the top and bottom of the threaded caps. Rubber pads are fixedly installed on opposite sides of the two clamping plates. Rectangular blocks are fixedly installed on one side of the multi-cylinder cylinder and on the other side of the two air vents. A sliding groove is opened on one side of the rectangular block. Sliding blocks are symmetrically slidably installed in the sliding groove. One end of the sliding block passes through the sliding groove and is fixed to the corresponding clamping plate. A bidirectional threaded rod is rotatably installed in the sliding groove. The top end of the bidirectional threaded rod passes through the two sliding blocks and the top of the sliding groove, extends to the outside, and is fixedly installed with a knob.
[0012] In this technical solution, personnel can rotate two knobs respectively. Rotating the knobs will drive the bidirectional threaded rod to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod will drive the two sliding blocks to move closer together. The two sliding blocks moving closer together will drive the two clamping plates to move closer together until the two clamping plates clamp the periphery of the threaded cap. At the same time, the clamping plates will compress the rubber pad to contract. At this time, the two clamping plates can hold the threaded cap. Under the action of the friction of the rubber pad, the threaded cap will not rotate, ensuring that the vent and the air pipe can be connected more tightly, ensuring that there is no air leakage in the vent and the air pipe, and effectively preventing air leakage.
[0013] In the above technical solution, the rubber pad is in contact with the periphery of the threaded cap, the bidirectional threaded rod is threadedly connected to the sliding block, the bidirectional threaded rod is provided with two sections of threads with opposite directions, and the upper end of the bidirectional threaded rod is rotatably connected to the rectangular block.
[0014] In this technical solution, it is ensured that the rubber pad can abut against the threaded cap, that the rotation of the bidirectional threaded rod can drive the two sliding blocks to move closer or further apart, and that the upper end of the bidirectional threaded rod can rotate normally within the rectangular block.
[0015] In the above technical solution, furthermore, a number of anti-slip patterns are fixedly installed on the periphery of the threaded cap, and the threaded cap is threadedly connected to the vent.
[0016] In this technical solution, the friction force of the threaded cap rotation is increased to ensure that the threaded cap can move on the vent.
[0017] In the above technical solution, one end of the vent is further connected to one end of the air tube.
[0018] In this technical solution, it is ensured that one end of the vent can be inserted into one end of the trachea.
[0019] In the above technical solution, furthermore, several of the anti-slip patterns are distributed in a ring with equal spacing.
[0020] In this technical solution, the distribution of several anti-slip patterns is ensured to be uniform.
[0021] Furthermore, in the above technical solution, the clamping plate has an arc-shaped structure.
[0022] In this technical solution, the structural stability of the clamping plate is ensured.
[0023] The beneficial effects of this utility model are:
[0024] This multi-cylinder anti-leakage sealing structure, through the arrangement of the air pipe, air inlet, sealing gasket 2, sealing gasket 1, threaded cap, anti-slip texture, and limiting components, ensures a tighter connection between the air inlet and the air pipe, preventing air leakage.

[0038] Example 1:
[0039] Please see Figure 1 - Figure 6 As shown, this embodiment provides a multi-cylinder cylinder anti-leakage sealing structure, including a multi-cylinder cylinder 1 and an electromagnetic pneumatic valve 8, and further including:
[0040] Two air vents 2 are fixedly installed on one side of the multi-cylinder cylinder 1. A sealing gasket 4 is fixedly installed on the periphery of the air vent 2. An air pipe 3 is sleeved on one end of the air pipe 2. A sealing gasket 5 that contacts the sealing gasket 4 is fixedly installed on one end of the air pipe 3. A threaded cap 6 is sleeved on the air pipe 3. One end of the threaded cap 6 extends to the periphery of the air vent 2. The other ends of the two air pipes 3 are fixed to the electromagnetic pneumatic valve 8.
[0041] A limiting assembly is located on the multi-cylinder cylinder 1 and is used to limit the two threaded caps 6.
[0042] During installation, personnel can first place one end of each of the two air tubes 3 onto one end of each of the two air ports 2. At this time, the sealing gasket 2 5 at one end of the air tube 3 will contact the sealing gasket 4 on the air port 2. Then, the threaded cap 6 is rotated. Under the action of the thread, the threaded cap 6 rotates and moves on the air port 2. The movement of the threaded cap 6 will drive the air tube 3 to move, so that one end of the air tube 3 squeezes the air port 2. At this time, the sealing gasket 4 and the sealing gasket 2 5 will deform, thereby sealing the air port 2 and the air tube 3. At the same time, under the anti-slip effect of several anti-slip textures 7, the friction of personnel rotating the threaded cap 6 can be increased, so that the threaded cap 6 can be rotated more easily.
[0043] Subsequently, personnel can use the limiting component to limit the threaded cap 6, so that the threaded cap 6 will not rotate, ensuring that the vent 2 and the air pipe 3 can be connected more tightly, ensuring that there will be no air leakage between the vent 2 and the air pipe 3, and effectively preventing air leakage.
[0044] Example 2:
[0045] This embodiment provides a multi-cylinder cylinder anti-leakage sealing structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:
[0046] Two limiting rods 14 are fixedly installed on one side of the multi-cylinder cylinder 1 and on one side of the two air ports 2. Clamping plates 12 are slidably installed on the limiting rods 14 and on the top and bottom of the threaded caps 6. Rubber pads 13 are fixedly installed on the opposite side of the two clamping plates 12. Rectangular blocks 9 are fixedly installed on one side of the multi-cylinder cylinder 1 and on the other side of the two air ports 2. A sliding groove 10 is opened on one side of the rectangular block 9. Sliding blocks 11 are symmetrically slidably installed in the sliding groove 10. One end of the sliding block 11 passes through the sliding groove 10 and is fixed to the corresponding clamping plate 12. A bidirectional threaded rod 15 is rotatably installed in the sliding groove 10. The top end of the bidirectional threaded rod 15 passes through the two sliding blocks 11 and the top of the sliding groove 10 and extends to the outside and is fixedly installed with a knob 16.
[0047] The operator can rotate two knobs 16. Rotating the knobs 16 will cause the bidirectional threaded rod 15 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 15 will cause the two sliding blocks 11 to move closer to each other. The two sliding blocks 11 moving closer to each other will cause the two clamping plates 12 to move closer to each other until the two clamping plates 12 clamp the periphery of the threaded cap 6. At the same time, the clamping plates 12 will squeeze the rubber pad 13 to contract. At this time, the two clamping plates 12 can hold the threaded cap 6. Under the action of the friction of the rubber pad 13, the threaded cap 6 will not rotate, ensuring that the vent 2 and the air pipe 3 can be connected more tightly, ensuring that there is no air leakage between the vent 2 and the air pipe 3, and effectively preventing air leakage.
[0048] Example 3:
[0049] This embodiment provides a multi-cylinder cylinder anti-leakage sealing structure. In addition to the technical solutions of the above embodiments, it also has the following technical features: the rubber pad 13 is in contact with the peripheral side of the threaded cap 6, the bidirectional threaded rod 15 is threadedly connected to the sliding block 11, the bidirectional threaded rod 15 is provided with two sections of threads with opposite directions, and the upper end of the bidirectional threaded rod 15 is rotatably connected to the rectangular block 9.
[0050] Specifically, this ensures that the rubber pad 13 can abut against the threaded cap 6, that the rotation of the bidirectional threaded rod 15 can drive the two sliding blocks 11 to move closer or further apart, and that the upper end of the bidirectional threaded rod 15 can rotate normally within the rectangular block 9.
[0051] Example 4:
[0052] This embodiment provides a multi-cylinder cylinder anti-leakage sealing structure. In addition to the technical solution of the above embodiment, it also has the following technical features: several anti-slip patterns 7 are fixedly installed on the periphery of the threaded cap 6, and the threaded cap 6 is threadedly connected to the vent 2.
[0053] This ensures that the friction force of the threaded cap 6 can be increased, and that the threaded cap 6 can move on the vent 2.
[0054] Example 5:
[0055] This embodiment provides a multi-cylinder cylinder anti-leakage sealing structure, which, in addition to the technical solution of the above embodiment, also has the following technical features: one end of the air inlet 2 is inserted and matched with one end of the air pipe 3.
[0056] Specifically, ensure that one end of the air inlet 2 can be inserted into one end of the air tube 3.
[0057] Example 6:
[0058] This embodiment provides a multi-cylinder cylinder anti-leakage sealing structure, which, in addition to the technical solution of the above embodiment, also has the following technical features: a plurality of anti-slip patterns 7 are distributed in an annular shape at equal intervals.
[0059] Among these measures, it is ensured that the distribution of several anti-slip patterns 7 is uniform.
[0060] Example 7:
[0061] This embodiment provides a multi-cylinder cylinder anti-leakage sealing structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the clamping plate 12 has an arc-shaped structure.
[0062] Among these measures, ensuring the structural stability of the clamping plate 12 is crucial.
[0063] Working principle: During installation, the operator can first place one end of each of the two air tubes 3 onto one end of each of the two air ports 2. At this time, the sealing gasket 2 5 at one end of the air tube 3 will contact the sealing gasket 4 on the air port 2. Then, rotate the threaded cap 6. Under the action of the thread, the threaded cap 6 will rotate and move on the air port 2. The movement of the threaded cap 6 will drive the air tube 3 to move, so that one end of the air tube 3 will squeeze the air port 2. At this time, the sealing gasket 4 and the sealing gasket 2 5 will deform, thereby sealing the air port 2 and the air tube 3. At the same time, under the anti-slip effect of several anti-slip textures 7, the friction of the operator rotating the threaded cap 6 can be increased, making the threaded cap 6 easier to rotate.
[0064] Subsequently, personnel can rotate the two knobs 16 respectively. Rotating the knobs 16 will drive the bidirectional threaded rod 15 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 15 will drive the two sliding blocks 11 to move closer to each other. The two sliding blocks 11 moving closer to each other will drive the two clamping plates 12 to move closer to each other until the two clamping plates 12 clamp the periphery of the threaded cap 6. At the same time, the clamping plates 12 will squeeze the rubber pad 13 to contract. At this time, the two clamping plates 12 can hold the threaded cap 6. Under the action of the friction of the rubber pad 13, the threaded cap 6 will not rotate, ensuring that the vent 2 and the air pipe 3 can be connected more tightly, ensuring that there is no air leakage between the vent 2 and the air pipe 3, and effectively preventing air leakage.
