Description

Technical Field

[0001] This application relates to the field of cylinders, and in particular to a novel integrated cylinder. Background Technology

[0002] A cylinder is the core actuator of a pneumatic system. It converts pneumatic pressure energy into mechanical energy by using compressed air to drive a piston in linear reciprocating or oscillating motion. It mainly consists of a cylinder barrel, piston, end caps, and seals, and is compact and durable. Based on the motion type, it can be divided into linear cylinders and rotary cylinders; based on the structure, it can be divided into single-acting (spring return) and double-acting (dual-sided air intake) types. Cylinders have advantages such as fast response, smooth operation, low cost, and adaptability to harsh environments, and are widely used in automation equipment, industrial robots, assembly lines, and other fields, serving as a key component for achieving precise control and efficient drive.

[0003] Existing cylinders require a connection between the solenoid valve and the cylinder via an air pipe during use, which necessitates a large installation space and a large amount of space for pipe layout. This can easily lead to a messy and chaotic pipework, making inspection and maintenance difficult, and it is not convenient for installation and use in small spaces. Summary of the Invention

[0004] To address the technical problem of the need for air pipes to connect the cylinder and solenoid valve, which occupies a large space, this application provides a novel integrated cylinder.

[0005] The novel integrated cylinder provided in this application adopts the following technical solution:

[0006] A novel integrated cylinder includes a cylinder body. A connector is provided at the bottom of the cylinder body, and an interface pipe is connected to the connector. A connection hole is provided on the side end of the connector, and a solenoid valve is connected to the connector and bolts through the connection hole. An air inlet, an outlet, and a discharge hole are provided on the inner side of the connector. One end of the air inlet is connected to the interface pipe, and the other end is connected to the air inlet of the solenoid valve. One end of the outlet is connected to the inside of the cylinder body, and the other end is connected to the working port of the solenoid valve. One end of the discharge hole is connected to the exhaust port of the solenoid valve, and the other end passes through the surface of the connector and is connected to the outside.

[0007] By adopting the above technical solution, the connector is connected to the solenoid valve with bolts, and the air intake, exhaust and working ports of the solenoid valve are connected through the air inlet, output and exhaust ports. The air pipe can be directly connected to the interface pipe, without the need for an additional air pipe, which simplifies the pipeline layout. Moreover, the solenoid valve and the cylinder are integrated as one unit, which occupies less space and is more convenient for use in small spaces.

[0008] Preferably, the connector is provided with a connecting part for insertion into the cylinder body, the outer side of the connecting part is provided with an installation groove, and two fixing pins are provided inside the cylinder body, with the fixing pins passing through the installation groove.

[0009] By adopting the above technical solution, the connector is fixed to the bottom of the cylinder by two fixing pins to achieve a fixing effect. Moreover, the mounting groove is annular, which allows the connector to be connected to the cylinder at any angle and the fixing pins to fix it. This allows the position of the solenoid valve to be changed at will, which is convenient for layout in small spaces.

[0010] Preferably, the outer side of the connecting part is provided with a plurality of embedding grooves, and a sealing ring is provided in the embedding groove, the outer side of the sealing ring abutting against the inner wall of the cylinder.

[0011] By adopting the above technical solution, the sealing ring can improve the sealing performance between the connecting parts and the cylinder.

[0012] Preferably, a piston is slidably disposed inside the cylinder, and spring grooves are provided on both the piston and the inner wall of the cylinder, and a return spring is provided between the two spring grooves, and a vent hole is provided at the bottom of the spring groove of the cylinder.

[0013] By adopting the above technical solution, air enters from one end of the cylinder, and the piston can only be reset by the elastic force of the reset spring. During reset, gas enters the cylinder from the vent hole, and the reset process is smooth.

[0014] Preferably, the piston is provided with a telescopic rod, and a mounting bracket is fixed at the end of the cylinder away from the connecting member. A pressure rod is rotatably connected to the mounting bracket, and the end of the telescopic rod abuts against one end of the pressure rod.

[0015] By adopting the above technical solution, the piston drives the telescopic rod to move. When the telescopic rod extends, it can lift one end of the pressure rod and lower the other end, thereby achieving the function of pressing.

[0016] Preferably, the connector has a through hole inside for connecting the air inlet and the outlet, and a closing mechanism is provided between the air inlet and the outlet and the through hole.

[0017] By adopting the above technical solution, after installing the solenoid valve, the closing mechanism is closed, so that gas must pass through the solenoid valve to enter the cylinder. However, if the solenoid valve is not installed, the closing mechanism can be opened, and the end of the output port and the air inlet port near the solenoid valve can be sealed, so that the cylinder part can be used as a separate cylinder, which is more convenient to use.

[0018] Preferably, an opening mechanism is provided on the inner side of the end of the air inlet and the output port near the solenoid valve. The opening mechanism includes a first inner retraction ring provided on the inner wall of the air inlet and the output port, and a first sealing ball is provided at the upper end of the first inner retraction ring. An inner retaining ring is provided at the upper end of the first sealing ball. A closing spring is provided between the inner retaining ring and the first sealing ball. A pressing block is connected to the first sealing ball. A groove is provided on the side wall of the connector, and the pressing block is located in the groove at the corresponding position and abuts against the solenoid valve.

[0019] By adopting the above technical solution, when the solenoid valve is installed, the compression block will squeeze the first sealing ball inward, so that the first sealing ball separates from the first inner shrink ring, ensuring the passage of gas. After the solenoid valve is disassembled, under the action of the closing spring, the first sealing ball abuts against the first inner shrink ring again, sealing the end of the air inlet and outlet near the solenoid valve installation position. No additional operation is required, making it more convenient to use.

[0020] Preferably, the closing mechanism includes a second inner retracting ring disposed inside the air inlet and outlet, and a second sealing ball disposed below the second inner retracting ring, the second sealing ball abutting against the second inner retracting ring, and a straight rod disposed between the first sealing ball and the second sealing ball.

[0021] By adopting the above technical solution, when the solenoid valve is installed, the second sealing ball abuts against the second inner shrinking ring, which can prevent airflow from passing through the perforation and ensure the normal use of the integrated cylinder. However, after the solenoid valve is removed, the second sealing ball will move synchronously with the first sealing ball. At this time, the second sealing ball separates from the second inner shrinking ring, and the gas can directly enter the cylinder body through the perforation without the need for the operator to manually close it, which is convenient to use.

[0022] Preferably, a sealing gasket is provided on the outer side of the air inlet, outlet, and discharge port near the opening of the solenoid valve.

[0023] By adopting the above technical solution, the sealing gasket can improve the sealing performance between the solenoid valve and the connecting parts, and prevent air leakage.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The solenoid valve is directly connected to the cylinder body via a connector, and the intake, exhaust and working ports of the solenoid valve are connected through the intake port, output port and exhaust port. The air pipe can be directly connected to the interface pipe, without the need for an additional air pipe, which simplifies the pipeline layout. Moreover, the solenoid valve and the cylinder are integrated as one unit, which occupies less space and is more convenient for use in small spaces. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a novel integrated cylinder.

[0035] Example 1:

[0036] Reference Figures 1-5 A novel integrated cylinder includes a cylinder body 1. A connector 2 is provided at the bottom of the cylinder body 1. The connector 2 is provided with a connecting part 9 for insertion into the cylinder body 1. An installation groove 10 is provided on the outer side of the connecting part 9. Two fixing pins 11 are arranged inside the cylinder body 1. The two fixing pins 11 can pass through the installation groove 10 to achieve connection and fixation.

[0037] The outer side of the connecting part 9 is also provided with several embedded grooves 12, and a sealing ring 13 is installed in each embedded groove 12. The outer side of the sealing ring 13 is tightly abutted against the inner wall of the cylinder body 1, so as to play a good sealing role.

[0038] The connector 2 is connected to an interface pipe 3, and its side end is provided with a connection hole 4. Through the connection hole 4 and with the aid of bolts, the solenoid valve 5 can be securely connected to the connector 2. The inner side of the connector 2 is provided with an air inlet 6, an output hole 7, and a discharge hole 8. One end of the air inlet 6 is connected to the interface pipe 3, and the other end is connected to the air inlet of the solenoid valve 5; one end of the output hole 7 is connected to the inside of the cylinder 1, and the other end is connected to the working port of the solenoid valve 5; one end of the discharge hole 8 is connected to the exhaust port of the solenoid valve 5, and the other end passes through the surface of the connector 2 and is connected to the outside. Moreover, sealing gaskets 30 are provided on the outer side of the air inlet 6, the output hole 7, and the discharge hole 8 near the opening of the solenoid valve 5, which can improve the sealing between the solenoid valve 5 and the connector 2 and prevent air leakage.

[0039] With the above configuration, connector 2 and solenoid valve 5 are assembled together using bolts. The air inlet 6, outlet 7, and exhaust 8 on connector 2 allow for seamless connection of the air inlet, exhaust, and working port of solenoid valve 5, achieving a seamless air circuit connection. In practical applications, only the air pipe needs to be directly connected to interface pipe 3, eliminating the need for additional air pipes. This ingenious design greatly simplifies the piping layout, making the entire air circuit system more concise and clear.

[0040] The connector 2 is securely fixed to the bottom of the cylinder body 1 by two fixing pins 11, ensuring the stability of the connection. Furthermore, the mounting groove 10 is designed as a ring structure, which gives the connector 2 great installation flexibility. No matter the angle from which the connector 2 is connected to the cylinder body 1, the fixing pins 11 can easily embed into the mounting groove 10, achieving reliable fixation. Based on this, the position of the solenoid valve 5 can be freely adjusted according to actual needs, providing great convenience for reasonable layout in small spaces.

[0041] Reference Figure 4 Inside the cylinder 1, a piston 14 is slidably mounted, and a telescopic rod 18 is installed on the piston 14. Spring grooves 15 are formed at corresponding positions on the inner wall of the cylinder 1, with two spring grooves 15 positioned opposite each other, and a return spring 16 is installed between them to provide elastic force for the piston 14 to return to its original position. Simultaneously, vent holes 17 are provided at the bottom of the spring grooves 15 on the cylinder 1 to ensure gas flow and prevent air pressure issues from affecting the normal sliding of the piston 14.

[0042] At the end of the cylinder 1 away from the connecting member 2, a mounting bracket is fixedly installed. A pressure rod 19 is provided on the mounting bracket by means of a rotatable connection. The end of the telescopic rod 18 abuts against one end of the pressure rod 19. In this way, the reciprocating motion of the piston 14 can drive the pressure rod 19 to swing accordingly through the telescopic rod 18.

[0043] With the above settings, air enters from one end of the cylinder 1, and the piston 14 is reset by the elastic force of the return spring 16. During reset, gas enters the cylinder 1 through the vent hole 17. The reset process is smooth. The piston 14 drives the telescopic rod 18 to move. When the telescopic rod 18 extends, it can lift one end of the pressure rod 19 and lower the other end, thereby achieving the pressing function.

[0044] The implementation principle of Embodiment 1 of this application is as follows:

[0045] The connector 2 and the solenoid valve 5 are assembled together by bolts. Through the air inlet 6, output 7, and exhaust 8 provided on the connector 2, the air inlet, exhaust, and working port of the solenoid valve 5 can be connected one-to-one, achieving seamless air circuit connection. In practical applications, only the air pipe needs to be directly connected to the interface pipe 3, without the need for additional air pipes. This ingenious design greatly simplifies the pipeline layout, making the entire air circuit system more concise and clear. Moreover, regardless of the angle from which the connector 2 is connected to the cylinder block 1, the fixing pin 11 can be smoothly embedded in the mounting groove 10, achieving reliable fixation. Based on this, the position of the solenoid valve 5 can be adjusted and changed at will according to actual needs, providing great convenience for reasonable layout in small spaces.

[0046] Example 2:

[0047] Reference Figure 6 The difference between this embodiment and Embodiment 1 is that the connector 2 has a through hole 20 inside, which serves to connect the air inlet 6 and the output hole 7. An opening mechanism is provided on the inner side of both the air inlet 6 and the output hole 7 near the solenoid valve 5.

[0048] The opening mechanism is as follows: a first inner retraction ring 21 is provided on the inner wall of the air inlet 6 and the outlet 7. A first sealing ball 22 is placed on the upper end of the first inner retraction ring 21, and an inner retaining ring 23 is provided above the first sealing ball 22. A closing spring 24 is installed between the inner retaining ring 23 and the first sealing ball 22, so that the first sealing ball 22 can tightly fit against the first inner retraction ring 21 under the action of the closing spring 24, achieving a preliminary seal. At the same time, a pressing block 26 is connected to the first sealing ball 22. A groove 25 is correspondingly opened on the side wall of the connector 2, and the pressing block 26 is exactly located in the groove 25, and the pressing block 26 abuts against the solenoid valve 5. When the solenoid valve 5 is activated, it will compress the pressing block 26, thereby pushing the first sealing ball 22 to move.

[0049] Furthermore, a closing mechanism is provided between the air inlet 6 and the outlet 7 and the through hole 20. The closing mechanism includes a second inner retraction ring 29 disposed inside the air inlet 6 and the outlet 7. A second sealing ball 28 is disposed below the second inner retraction ring 29, and the second sealing ball 28 abuts against the second inner retraction ring 29 to provide a seal. The first sealing ball 22 and the second sealing ball 28 are connected by a straight rod 27. When the first sealing ball 22 is pushed, it moves the second sealing ball 28 via the straight rod 27, thereby controlling the opening and closing of the air passage.

[0050] With the above setup, once the solenoid valve 5 is installed, the compression block 26 is compressed by the solenoid valve 5, which in turn pushes the first sealing ball 22 inward, causing the first sealing ball 22 to separate from the first inner shrink ring 21. This allows gas to pass smoothly through the channel. Simultaneously, the second sealing ball 28, under the action of the straight rod 27, tightly abuts against the second inner shrink ring 29, effectively blocking the airflow from directly passing through the perforation 20. This ensures that the gas must pass through the solenoid valve 5 before entering the cylinder 1, achieving orderly conduction and control of the air path.

[0051] Without the solenoid valve 5 installed, the closing spring 24 will exert its elasticity, causing the first sealing ball 22 to re-engage tightly with the first inner shrink ring 21, sealing the ends of the air inlet 6 and outlet 7 near the solenoid valve 5 installation position to prevent gas leakage. At this time, since the first sealing ball 22 and the second sealing ball 28 are connected by the straight rod 27, the second sealing ball 28 will move synchronously with the first sealing ball 22, separating from the second inner shrink ring 29. In this way, gas can directly enter the cylinder 1 through the perforation 20 without manual shut-off, greatly simplifying operation.

[0052] The implementation principle of Embodiment 2 of this application is as follows:

[0053] After installing the solenoid valve 5, closing the closing mechanism and opening the opening mechanism will allow gas to enter the cylinder 1 only after passing through the solenoid valve 5. However, without installing the solenoid valve 5, opening the closing mechanism and closing the opening mechanism will allow gas to directly enter the cylinder 1 through the interface pipe 3, thus allowing the cylinder to be used as a separate cylinder, which is more convenient.

[0054] In summary, this device integrates the solenoid valve 5 and the cylinder into a single unit, significantly reducing the usable space and improving the overall aesthetics, making it suitable for use in small spaces.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
