DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides a vertical air compressor, such as Figures 1 to 7As shown, it includes an air compressor body 1, an exhaust pipe 2 is provided on the outside of the air compressor body 1, a first ring plate 3 is slidably installed inside the exhaust pipe 2, a second ring plate 22 is slidably sleeved on the outside of the exhaust pipe 2, the first ring plate 3 and the second ring plate 22 are connected by a sealing sleeve 4, the sealing sleeve 4 is sleeved on the outside of the exhaust pipe 2, a bracket 5 is fixedly installed on the top of the air compressor body 1, an electric push rod 6 is fixedly installed on the top wall of the bracket 5, the telescopic end of the electric push rod 6 extends to the outside of the bracket 5 and is fixedly connected with a vertical plate 7, the bottom of the vertical plate 7 is fixedly connected with a pipe 8 through a fixing ring, one end of the pipe 8 extends into the exhaust pipe 2, both sides of the sealing sleeve 4 are respectively in conflict with the pipe 8 and the exhaust pipe 2, a driving component for driving it to slide along the inside of the exhaust pipe 2 is provided on the first ring plate 3, and a control component that cooperates with the driving component and can drive the electric push rod 6 to extend and retract is provided on the outside of the pipe 8.

[0028] When in use, the other end of the pipeline 8 is connected to an external device that needs to input high-pressure air. The pipeline 8 is composed of a stainless steel pipe and a hose. The stainless steel pipe is fixed with a fixing ring, and the stainless steel pipe part extends into the exhaust pipe 2. The air compressor body 1 is an air compressor in the prior art. High-pressure gas is produced by the air compressor body 1 and input into the equipment through the exhaust pipe 2 and the pipeline 8. The airtightness between the pipeline 8 and the exhaust pipe 2 can be improved by the sealing sleeve 4. With long-term use, the side of the sealing sleeve 4 that is in contact with the pipeline 8 and the exhaust pipe 2 is affected by the gas because it is inside the exhaust pipe 2, and the aging speed is fast. When aging occurs, it will affect the airtightness of the connection between the pipeline 8, the exhaust pipe 2 and the sealing sleeve 4. At this time, the control component controls the electric push rod 6 to extend so as to drive the vertical plate 7, the fixing ring, and the pipeline 8 to move, so that the pipeline 8 and the exhaust The exhaust pipe 2 is separated, and then the control component controls the driving component to drive the first ring plate 3 to move it toward the inside of the exhaust pipe 2, thereby pulling the sealing sleeve 4 and the second ring plate 22 to move accordingly, so that the unaged side of the sealing sleeve 4 located on the outside is moved into the exhaust pipe 2, and then the driving component stops moving, and the control component drives the electric push rod 6 to shorten and reset, and vice versa, the pipe 8 can be reset, so that the pipe 8 enters the exhaust pipe 2 again and contacts the outside of the sealing sleeve 4. At this time, the replaced unaged two sides of the sealing sleeve 4 respectively contact the pipe 8 and the exhaust pipe 2, so that the airtightness of the connection between the pipe 8 and the exhaust pipe 2 can be improved, and the automatic replacement of the aging part of the sealing sleeve 4 is realized, so that when there is no one on duty, when gas leakage occurs due to aging of the sealing sleeve 4, the sealing sleeve 4 can be automatically replaced, thereby ensuring the normal operation of the equipment.

[0029] like Figure 3 and Figure 6 As shown, the driving assembly includes a connecting plate 9 fixedly connected to the outside of the first ring plate 3, a motor 10 is fixedly installed on the top of the connecting plate 9, and a roller 11 is fixedly connected to the output shaft of the motor 10, and the outer side of the roller 11 contacts the inner wall of the exhaust pipe 2.

[0030] The control component drives the output shaft of the motor 10 to rotate, thereby driving the roller 11 to rotate. The roller 11 relies on the friction between the inner wall of the exhaust pipe 2 to move into the exhaust pipe 2, and then drives the motor 10, the connecting plate 9, the first ring plate 3, the sealing sleeve 4, and the second ring plate 22 to move accordingly, so that the aging surface of the sealing sleeve 4 can be switched.

[0031] like Figure 3 As shown, the control component includes a circular plate 12 fixedly mounted on the outside of the pipe 8, a groove is provided on the side of the circular plate 12 close to the sealing sleeve 4, a pressure sensor 13 is provided in the groove, the circular plate 12 is in contact with the outside of the sealing sleeve 4, the pressure sensor 13 is located in the area formed by the circular plate 12, the sealing sleeve 4 and the pipe 8, and the pressure sensor 13 cooperates with the electric push rod 6 and the motor 10.

[0032] When the sealing sleeve 4 contacts the pipe 8 and the exhaust pipe 2, the gas will leak. The leaked gas will enter the area formed by the annular plate 12, the sealing sleeve 4 and the pipe 8. As the amount of gas increases, the pressure sensor 13 will be squeezed. At this time, the pressure sensor 13 controls the electric push rod 6 to perform subsequent extension and contraction, and controls the start and stop of the motor 10.

[0033] like Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a movable opening is equidistantly provided around one end of the pipe 8 extending into the exhaust pipe 2, and a slide groove 14 is symmetrically provided on the inner wall of the movable opening. A slider 15 is slidably installed in the slide groove 14, and an extrusion wheel 16 is rotatably installed between every two adjacent sliders 15. An extrusion component is provided at the bottom of the slider 15 for driving it to move in a direction away from the center of the pipe 8.

[0034] When the pipe 8 is inserted into the exhaust pipe 2, when the end of the pipe 8 just enters the exhaust pipe 2, the extrusion assembly drives the slider 15 to move with the extrusion wheel 16 in the direction away from the center of the pipe 8, and multiple extrusion wheels 16 squeeze the sealing sleeve 4 to stretch the sealing sleeve 4, so that in the subsequent process of inserting the pipe 8 into the exhaust pipe 2, the contact surface between the sealing sleeve 4 and the outer side of the pipe 8 is small, and the friction force is small, so that the pipe 8 will not push the sealing sleeve 4 due to the large friction between the sealing sleeve 4, causing wrinkles to form, resulting in the situation that the wrinkles accumulate between the first ring plate 3 and the pipe 8 during the advancement of the pipe 8, affecting the entry of the pipe 8, ensuring that the pipe 8 can smoothly enter the exhaust pipe 2 and reset. When the pipe 8 is reset, the extrusion assembly drives the slider 15 to reset it, so that the extrusion wheel 16 is reset, and the stretched part of the sealing sleeve 4 is reset to fit the pipe 8.

[0035] like Figure 3 , Figure 4 , Figure 5and Figure 7 As shown, the extrusion assembly includes a push rod 17 fixedly connected to the bottom of the slider 15, and the end of the push rod 17 away from the slider 15 passes through the inner wall of the slide groove 14 and extends to the inside of the pipe 8. A mounting ring 21 is fixedly installed on the inner wall of the exhaust pipe 2, and a connecting rod 18 is symmetrically fixedly installed on the side of the mounting ring 21 close to the pipe 8. An extrusion ring 19 is fixedly installed on one end of the two connecting rods 18 away from the mounting ring 21. The end of the extrusion ring 19 away from the connecting rod 18 is flush with the end of the exhaust pipe 2, and both ends of the extrusion ring 19 are provided with inclined surfaces 20, which can contact the push rod 17, and the side of the slider 15 away from the push rod 17 is fixedly connected to the inner wall of the slide groove 14 through a spring 23.

[0036] When the pipe 8 moves with the slider 15, the extrusion wheel 16 and the push rod 17, when the end of the pipe 8 just enters the exhaust pipe 2, the push rod 17 conflicts with the inclined surface 20. As the pipe 8 enters, the push rod 17 moves along the inclined surface 20, pushing the slider 15 and the extrusion wheel 16 to move away from the center of the pipe 8. At the same time, the spring 23 is compressed and deformed to generate a force. At this time, the extrusion wheel 16 opens the sealing sleeve 4. Later, when the pipe 8 enters the exhaust pipe 2, the push rod 17 conflicts with the horizontal surface of the extrusion ring 19, and the extrusion wheel 16 rolls. When the pipe 8 is about to be reset, the push rod 17 contacts the inclined surface 20 on the other side and moves along its surface. At this time, the spring 23 releases the force to reset the slider 15 and the extrusion wheel 16, so that the extrusion wheel 16 cancels the extrusion of the sealing sleeve 4.

[0037] like Figure 6 As shown, the sealing sleeve 4 is specifically configured as a sleeve-shaped component made of soft rubber.

[0038] The sealing sleeve 4 can ensure the airtightness of the connection between the pipeline 8 and the exhaust pipe 2 .

[0039] like Figures 2 to 3 As shown, a slot is provided on one side of the first ring plate 3 and the second ring plate 22 close to the sealing sleeve 4, and the end of the sealing sleeve 4 extends into the slot. The inner side of the first ring plate 3 and the outer side of the second ring plate 22 are equidistantly provided with screw holes connected to the slot, and bolts are threadedly connected in the screw holes, and the bolts are in contact with the end of the sealing sleeve 4.

[0040] The bolts can be rotated to be separated from the sealing sleeve 4 so that the sealing sleeve 4 can be replaced after all surfaces thereof have aged.

[0041] like Figure 3 As shown, the roller 11 is specifically a rubber wheel made of high temperature resistant rubber.

[0042] The roller 11 can move along the inner wall of the exhaust pipe 2 by relying on the friction between the roller 11 and the inner wall of the exhaust pipe 2 .

[0043] Working principle: When in use, the other end of the pipeline 8 is connected to the equipment that needs to input high-pressure air from the outside. The pipeline 8 is composed of a stainless steel pipe and a hose. The stainless steel pipe is fixed with a fixing ring, and the stainless steel pipe part extends into the exhaust pipe 2. The air compressor body 1 is an air compressor in the prior art. The high-pressure gas is produced by the air compressor body 1 and input into the equipment through the exhaust pipe 2 and the pipeline 8. The airtightness between the pipeline 8 and the exhaust pipe 2 can be improved by the sealing sleeve 4. With long-term use, the side where the sealing sleeve 4 contacts the pipeline 8 and the exhaust pipe 2 is affected by the gas inside the exhaust pipe 2, and the aging speed is fast. When aging occurs, it will affect the airtightness of the connection between the pipeline 8, the exhaust pipe 2 and the sealing sleeve 4. When the part where the sealing sleeve 4 contacts the pipeline 8 and the exhaust pipe 2 is aged, the gas will leak. The leaked gas will enter the area formed by the annular plate 12, the sealing sleeve 4, and the pipeline 8. As the gas increases, the pressure sensor 13 will be squeezed. At this time, the pressure sensor 13 controls the electric push rod 6 to extend so that the vertical push rod 6 is driven The plate 7, the fixing ring and the pipe 8 move, so that the pipe 8 is separated from the exhaust pipe 2. Then the pressure sensor 13 controls the output shaft of the motor 10 to rotate, thereby driving the roller 11 to rotate. The roller 11 relies on the friction between the inner wall of the exhaust pipe 2 to move into the exhaust pipe 2, and then drives the motor 10, the connecting plate 9, the first ring plate 3, the sealing sleeve 4, and the second ring plate 22 to move accordingly, so that the side of the sealing sleeve 4 that is not aged outside moves into the exhaust pipe 2. Then the pressure sensor 13 controls the motor 10 to stop and drives the electric push rod 6 to shorten and reset. Otherwise, the pipe 8 can be reset, so that the pipe 8 enters the exhaust pipe 2 again and contacts the outside of the sealing sleeve 4. At this time, the two sides of the replaced and unaged sealing sleeve 4 contact the pipe 8 and the exhaust pipe 2 respectively, so that the airtightness of the connection between the pipe 8 and the exhaust pipe 2 can be improved. So far, the automatic replacement of the aged part of the sealing sleeve 4 is realized, so that when there is no one on duty, when gas leakage occurs due to the aging of the sealing sleeve 4, the sealing sleeve 4 can be automatically replaced, thereby ensuring the normal operation of the equipment;When the pipe 8 is inserted into the exhaust pipe 2, the pipe 8 moves with the slider 15, the extrusion wheel 16 and the push rod 17. When the end of the pipe 8 just enters the exhaust pipe 2, the push rod 17 conflicts with the inclined surface 20. As the pipe 8 enters, the push rod 17 moves along the inclined surface 20, pushing the slider 15 and the extrusion wheel 16 to move away from the center of the pipe 8. At the same time, the spring 23 is compressed and deformed to generate a force. At this time, the extrusion wheel 16 opens the sealing sleeve 4. Later, when the pipe 8 enters the exhaust pipe 2, the push rod 17 conflicts with the horizontal surface of the extrusion ring 19, and the extrusion wheel 16 rolls. By opening the sealing sleeve 4, the contact surface between the sealing sleeve 4 and the outer side of the pipe 8 is small, the friction is small, and the pipe 8 is The pipe 8 will not push the sealing sleeve 4 due to the large friction between it and the sealing sleeve 4, causing wrinkles to accumulate between the first ring plate 3 and the pipe 8 during the advancement of the pipe 8, which will affect the entry of the pipe 8. This ensures that the pipe 8 can smoothly enter the exhaust pipe 2 and reset. When the pipe 8 is about to reset, the push rod 17 contacts the inclined surface 20 on the other side and moves along its surface. At this time, the spring 23 releases the force to reset the slider 15 and the extrusion wheel 16, so that the extrusion wheel 16 cancels the extrusion of the sealing sleeve 4. Finally, the opened part of the sealing sleeve 4 is reset and fits the pipe 8. When the pipe 8 is pulled out, the extrusion wheel 16 will open the sealing sleeve 4, and then after it is pulled out, the extrusion wheel 16 resets. ;

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
