[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0040] The following is for reference. Figures 1-11 The fan assembly 100 according to an embodiment of the present utility model can greatly reduce the transmission of vibration of the fan body 1, reduce low-frequency resonance sound from the source, and at the same time, make the fan body 1 vibrate only along the connection direction between the fan body 1 and the fan support 2 without deflection, thereby improving the safety of the fan assembly 100.
[0041] like Figures 1-11 As shown, a fan assembly 100 according to an embodiment of the present invention includes: a fan body 1, a fan bracket 2, and at least one vibration damper assembly 3.
[0042] The main body of the fan 1 is mainly used to deliver air and exhaust air to achieve ventilation. The main body of the fan 1 is provided with a fan mounting base 11, which is used to support and fix the main body of the fan 1 to ensure the installation stability and reliability of the main body of the fan 1.
[0043] The fan bracket 2 is suitable for connection with the working surface. It can be connected to the working surface by means of threaded connection, adhesive connection or other connection methods, so that the fan bracket 2 can be stably installed on the working surface, ensuring that the fan bracket 2 can work stably and safely, and preventing loosening during operation that could cause noise or safety hazards.
[0044] Furthermore, the fan assembly 100 includes at least one vibration damper assembly 3, which includes a housing 31 and a piston rod 32, the piston rod 32 being axially movably mounted on the housing 31.
[0045] In other words, one, two, three, or more vibration damper assemblies 3 can be installed. The vibration damper assemblies 3 are used to reduce the vibration and noise generated during the operation of the fan assembly 100, especially to reduce low-frequency resonance noise, to ensure that the fan assembly 100 can operate quietly and safely, and to protect the environment. The vibration damper assembly 3 includes a housing 31 and a piston rod 32. The piston rod 32 is axially movably installed in the housing 31, that is, the interior of the housing 31 is hollow, and the piston rod 32 is installed inside the housing 31 and can move axially relative to the housing 31 to achieve the buffering and absorption of vibration.
[0046] The outer casing 31 includes a side wall 314 and a bottom wall 312. A sealing part 8 is provided between the piston rod 32 and the side wall 314. A pneumatic buffer chamber 4 is formed between the piston rod 32, the side wall 314, the sealing part 8, and the bottom wall 312. That is, the sealing part 8 is tightly pressed against the piston rod 32 and the side wall 314, so that a sealed pneumatic buffer chamber 4 is formed between the piston rod 32, the side wall 314, the sealing part 8, and the bottom wall 312 and is separated from the outside. A certain amount of air or other gas can be sealed in the pneumatic buffer chamber 4 to form an air spring. Thus, the pneumatic buffer chamber 4 can withstand the action of pressure and tension to absorb vibration. When the piston rod 32 is subjected to a load, the gas in the pneumatic buffer chamber 4 can be compressed to increase the air pressure, thereby achieving the buffering and absorption of vibration. When the load on the piston rod 32 decreases, the gas in the pneumatic buffer chamber 4 expands and the air pressure decreases.
[0047] Furthermore, one of the fan mounting base 11 and the fan bracket 2 is connected to the housing 31, and the other of the fan mounting base 11 and the fan bracket 2 is connected to the piston strut 32.
[0048] In other words, the fan mounting base 11 can be connected to the outer casing 31, and the fan bracket 2 can be connected to the piston strut 32, or the fan mounting base 11 can be connected to the piston strut 32, and the fan bracket 2 can be connected to the outer casing 31, so that the vibration damper assembly 3 is connected between the fan mounting base 11 and the fan bracket 2, which can absorb and reduce the vibration transmitted from the fan mounting base 11 to the fan bracket 2.
[0049] It should be noted that when the fan body 1 delivers air, the air is discharged in the direction away from the fan support 2. The reaction force of the air on the fan body 1 is opposite to the air discharge direction, that is, the direction in which the fan body 1 is closer to the fan support 2. Therefore, the vibration direction of the fan assembly 100 is the direction in which the fan body 1 is connected to the fan support 2. The vibration generated by the fan body 1 will be transmitted to the fan support 2 along the connection direction between the fan body 1 and the fan support 2. During the transmission process, it will resonate with some other components, generating low-frequency resonance sound. In the prior art, vibration reduction is achieved by setting vibration damping materials such as rubber or springs at the bottom of the fan support 2 or the fan body 1. However, vibration damping materials are difficult to limit the lateral tilt of the fan body 1, which poses a significant safety hazard.
[0050] In this application, the vibration damper assembly 3 is installed between the fan mounting base 11 and the fan bracket 2. Since one axial end of the piston rod 32 is connected to the fan mounting base 11 or the fan bracket 2, the direction of movement of the piston rod 32 is the vibration direction of the fan assembly 100. That is, the piston rod 32 can only reciprocate along the connection direction between the fan body 1 and the fan bracket 2, which is also the connection direction between the fan mounting base 11 and the fan bracket 2, to achieve a buffering and vibration reduction effect. This can greatly reduce the transmission of vibration of the fan body 1 and reduce low-frequency resonance sound from the source. At the same time, the vibration damper assembly 3 ensures that the fan body 1 can only vibrate along the connection direction between the fan body 1 and the fan bracket 2 without tilting, thus avoiding safety hazards and improving the safety of the fan assembly 100.
[0051] Furthermore, the fan assembly 100 in this embodiment can discharge air vertically upwards, vertically downwards, or laterally. When discharging air vertically upwards, the fan bracket 2 can be vertically connected to the working surface and attached to the upper surface of the working surface. When discharging air laterally, the fan bracket 2 can be horizontally connected to the working surface and attached to the side of the working surface. Figure 1 As shown, the air outlet is vertically upward, meaning the vibration direction of the fan assembly 100 is up and down. By setting a vibration damper assembly 3 that can only move in the up and down direction, the fan body 1 can only vibrate in the up and down direction without lateral deviation, which improves the safety of the fan assembly 100. At the same time, it greatly reduces the vibration transmitted downward by the fan body 1 and significantly improves the low-frequency resonance sound.
[0052] According to the embodiment of the present invention, the fan assembly 100, by installing at least one vibration damper assembly 3 between the fan mounting base 11 and the fan bracket 2, can greatly reduce the transmission of vibration of the fan body 1, reduce low-frequency resonance noise from the source, and at the same time, make the fan body 1 vibrate only along the connection direction between the fan body 1 and the fan bracket 2 without deflection, thereby improving the safety of the fan assembly 100.
[0053] In some embodiments, the outer peripheral wall of the piston rod 32 and the inner peripheral wall of the housing side wall 314 together define a sealing groove 3211, or one of the outer peripheral wall of the piston rod 32 and the inner peripheral wall of the housing side wall 314 has a sealing groove 3211 that opens toward the other. The sealing part 8 is installed in the sealing groove 3211 and matches the sealing groove 3211, thereby achieving a fixed installation of the sealing part 8, so that the sealing part 8 is tightly pressed between the outer peripheral wall of the piston rod 32 and the inner peripheral wall of the housing side wall 314, thereby sealing the air pressure buffer chamber 4, sealingly separating the air pressure buffer chamber 4 from the external environment, and preventing gas in the air pressure buffer chamber 4 from leaking into the external environment.
[0054] Specifically, such as Figure 11As shown, the outer peripheral wall of the piston rod 32 has a sealing groove 3211 that opens toward the inner peripheral wall of the outer casing side wall 314. The sealing groove 3211 can be constructed as a semi-circle or a circle. The sealing part 8 can be installed in the sealing groove 3211 to fix the sealing part 8 and prevent the sealing part 8 from falling off. Figure 11 As shown, when the sealing groove 3211 is constructed as a semi-circle, the cross-sectional diameter of the sealing part 8 can be set to be greater than the gap between the sealing groove 3211 and the inner peripheral wall of the air pressure buffer chamber 4. In this way, a part of the sealed part 8 after being squeezed can be located in the sealing groove 3211, and the other part can be pressed against the inner peripheral wall of the air pressure buffer chamber 4 to improve the sealing performance.
[0055] In practical design, such as Figure 11 As shown, the outer casing sidewall 314 can be constructed as a cylinder, and the lower end of the piston rod 32 can be constructed as a cylindrical piston portion 321. The radial dimension of the piston portion 321 matches the radial dimension of the outer casing sidewall 314, so that the outer peripheral wall of the piston portion 321 can fit against the inner peripheral wall of the outer casing sidewall 314 and move up and down. The piston portion 321 and the outer casing sidewall 314 can be configured as an interference fit, that is, the outer diameter of the piston portion 321 is larger than the inner diameter of the outer casing sidewall 314, so that the outer peripheral wall of the piston rod 32 can fit tightly against the inner peripheral wall of the outer casing sidewall 314 and move up and down.
[0056] Furthermore, a grease-based lubricant can be applied to the outer peripheral wall of the piston portion 321 and the inner peripheral wall of the outer casing side wall 314, thereby allowing the piston rod 32 to slide smoothly up and down along the inner peripheral wall of the outer casing side wall 314.
[0057] In other embodiments, the sealing portion 8 is configured as an annular structure, and the sealing portion 8 extends circumferentially along the piston rod 32.
[0058] Therefore, the air pressure buffer chamber 4 can be sealed in the entire circumferential direction, preventing gaps from forming at any position between the outer peripheral wall of the piston rod 32 and the inner peripheral wall of the outer casing side wall 314, which would cause gas leakage in the air pressure buffer chamber 4.
[0059] Specifically, such as Figure 11 As shown, the sealing part 8 is constructed as an annular sealing ring. The sealing part 8 extends circumferentially along the piston rod 32 to seal the air pressure buffer chamber 4 throughout the entire circumferential direction.
[0060] In other embodiments, there are multiple sealing portions 8.
[0061] In other words, two or more sealing parts 8 can be provided. Providing multiple sealing parts 8 can improve the sealing effect and prevent the piston rod 32 from tilting, thereby ensuring that the piston rod 32 moves stably in the vertical direction. Figure 11As shown, two sealing parts 8 are provided, which are spaced apart in the vertical direction. One end of the sealing part 8 is pressed against the outer peripheral wall of the piston rod 32, and the other end of the sealing part 8 is pressed against the inner peripheral wall of the outer shell side wall 314. Thus, the sealing part 8 is tightly pressed between the piston rod 32 and the outer shell side wall 314, thereby sealing the air pressure buffer chamber 4 and sealingly separating the air pressure buffer chamber 4 from the external environment to prevent gas in the air pressure buffer chamber 4 from leaking into the external environment.
[0062] In some embodiments, the housing 31 is provided with at least one first connection portion for detachably connecting to one of the fan mounting base 11 and the fan bracket 2.
[0063] In other words, one, two, or more first connecting parts can be provided on the outer casing 31. The first connecting parts can be detachably connected to the fan mounting base 11. That is, the first connecting parts and the fan mounting base 11 can be connected by detachable connection methods such as snap-fit connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan mounting base 11. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan mounting base 11 is damaged, the vibration damper assembly 3 or the fan mounting base 11 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.
[0064] Alternatively, the first connecting part can be detachably connected to the fan bracket 2. That is, the first connecting part and the fan bracket 2 can be connected by a detachable connection method such as snap-fit connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan bracket 2. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan bracket 2 is damaged, the vibration damper assembly 3 or the fan bracket 2 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.
[0065] By setting multiple first connection parts, the fan mounting base 11 or fan bracket 2 can be connected to the vibration damper assembly 3 at multiple locations through multiple first connection parts. This can improve the connection stability and reliability between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2, prevent the connection between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2 from becoming loose or falling off. Moreover, if one of the first connection parts fails, the other first connection parts can still be connected normally and securely, thereby improving the working reliability of the vibration damper assembly 3.
[0066] In other embodiments, the piston rod 32 is provided with at least one second connection for detachably connecting to another of the fan mounting base 11 and the fan bracket 2.
[0067] In other words, one, two, or more second connecting parts can be provided on the piston strut 32. The second connecting parts can be detachably connected to the fan mounting base 11. That is, the second connecting parts and the fan mounting base 11 can be connected by detachable connection methods such as snap-fit connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan mounting base 11. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan mounting base 11 is damaged, the vibration damper assembly 3 or the fan mounting base 11 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.
[0068] Alternatively, the second connecting part can be detachably connected to the fan bracket 2. That is, the second connecting part and the fan bracket 2 can be connected by a detachable connection method such as snap-fit connection or threaded connection, thereby realizing the connection between the vibration damper assembly 3 and the fan bracket 2. This facilitates installation and disassembly. When the vibration damper assembly 3 or the fan bracket 2 is damaged, the vibration damper assembly 3 or the fan bracket 2 can be quickly and easily disassembled for repair and replacement, which is flexible and convenient.
[0069] By setting multiple second connection parts, the fan mounting base 11 or fan bracket 2 can be connected to the vibration damper assembly 3 at multiple locations through multiple second connection parts. This can improve the connection stability and reliability between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2, prevent the connection between the vibration damper assembly 3 and the fan mounting base 11 or fan bracket 2 from becoming loose or falling off. Moreover, if one of the second connection parts fails, the other first connection parts can still be connected normally and securely, thereby improving the working reliability of the vibration damper assembly 3.
[0070] In some embodiments, the first connection portion is configured as a first connecting post 311 protruding from the housing 31 in a direction away from the piston rod 32. The first connecting post 311 passes through one of the fan mounting base 11 and the fan bracket 2 and is axially limited and fixed by the first positioning member 51.
[0071] Specifically, such as Figure 9 and Figure 10 As shown, the first connecting part is configured such that the outer casing 31 faces away from the piston rod 32, i.e. Figure 10 As shown in the upper and lower part, a first connecting post 311 protrudes from the lower part of the outer shell 31. The first connecting post 311 can be inserted into the fan mounting base 11 or the fan bracket 2. The first positioning member 51 axially limits and fixes the first connecting post 311, that is, restricts the axial movement of the first connecting post 311, so as to achieve a stable connection between the first connecting post 311 and the fan mounting base 11 or the fan bracket 2, thereby achieving a stable installation of the vibration damper assembly 3.
[0072] In some embodiments, the fan bracket 2 is provided with a first through hole 21, and the first connecting column 311 passes through the first through hole 21.
[0073] like Figure 5 As shown, the fan bracket 2 is provided with a first through hole 21 that runs through the thickness direction. The shape and size of the first through hole 21 are adapted to the first connecting column 311, so that the first connecting column 311 can pass smoothly through the first through hole 21 to realize the connection between the fan bracket 2 and the vibration damper assembly 3.
[0074] The outer side of the outer casing 31 presses against one side of the fan bracket 2, and the first positioning member 51 presses against the other side of the fan bracket 2.
[0075] like Figure 5 As shown, after the first connecting post 311 passes through the first through hole 21, the outer side of the outer shell 31 abuts against the side of the fan bracket 2 near the outer shell 31. At the same time, the first positioning member 51 abuts against the other side of the fan bracket 2, that is, the side away from the outer shell 31. Thus, the fan bracket 2 is clamped between the outer side of the outer shell 31 and the first positioning member 51, thereby achieving relative fixation between the piston rod 32 and the fan mounting base 11.
[0076] In actual design, an external thread can be provided on the outer periphery of the first connecting post 311, and the first positioning member 51 can be constructed as a first positioning nut. The first positioning nut is provided with an internal thread that matches the external thread. Thus, after the first connecting post 311 passes through the first through hole 21, the first positioning nut can be sleeved on the outside of the first connecting post 311, and the first positioning nut can be tightened by thread engagement to achieve axial positioning and fixation of the first connecting post 311.
[0077] In some embodiments, the second connection portion is configured as a second connecting post 3221 extending outside the housing 31. The second connecting post 3221 passes through another of the fan mounting base 11 and the fan bracket 2 and is axially limited and fixed by the second positioning member 52.
[0078] Specifically, such as Figure 9 As shown, the second connecting part is constructed as a second connecting post 3221 extending outside the outer shell 31. The second connecting post 3221 can be inserted into the fan mounting base 11 or the fan bracket 2. The second positioning member 52 is used to axially limit and fix the second connecting post 3221, that is, to restrict the axial movement of the second connecting post 3221, so as to achieve a stable connection between the second connecting post 3221 and the fan mounting base 11 or the fan bracket 2, thereby achieving a stable installation of the vibration damper assembly 3.
[0079] In some embodiments, the fan mounting base 11 is provided with a second through hole 111, and the second connecting post 3221 passes through the second through hole 111.
[0080] like Figure 5 As shown, the fan mounting base 11 is provided with a second through hole 111 that extends along the thickness direction. The shape and size of the second through hole 111 are adapted to the second connecting post 3221, so that the second connecting post 3221 can pass smoothly through the second through hole 111 to realize the connection between the fan mounting base 11 and the vibration damper assembly 3.
[0081] The second connecting column 3221 forms a limiting step surface 3121, which abuts against one side of the fan mounting base 11, and the second positioning member 52 abuts against the other side of the fan mounting base 11.
[0082] like Figures 9-11 As shown, the radial dimension of the second connecting post 3221 is smaller than the radial dimension of the piston rod 32, thus forming a limiting step surface 3121 at the end of the second connecting post 3221, i.e., at the connection between the piston rod 32 and the second connecting post 3221. The limiting step surface 3121 is used to support the fan mounting base 11, as shown. Figure 5 As shown, after the second connecting column 3221 passes through the second through hole 111, the limiting step surface 3121 presses against the side of the fan mounting base 11 near the outer shell 31. At the same time, the second positioning member 52 presses against the other side of the fan mounting base 11, that is, the side away from the outer shell 31. Thus, the fan mounting base 11 is clamped between the second positioning member 52 and the limiting step surface 3121, realizing the relative fixation of the piston rod 32 and the fan mounting base 11. Then, when the fan body 1 vibrates, the vibration will be transmitted to the piston rod 32, so that the piston rod 32 can move up and down in the air pressure buffer chamber 4 to buffer and absorb the vibration.
[0083] In actual design, an external thread can be provided on the outer periphery of the second connecting column 3221, and the second positioning member 52 can be constructed as a second positioning nut. The second positioning nut is provided with an internal thread that matches the external thread. After the second connecting column 3221 passes through the second through hole 111 and the fan mounting seat 11 abuts against the limiting step surface 3121, the second positioning nut can be sleeved on the outside of the second connecting column 3221. The second positioning nut is tightened by thread engagement to achieve axial limiting and fixing of the second connecting column 3221.
[0084] In some embodiments, at least two fan brackets 2 are provided, and the at least two fan brackets 2 are spaced apart. Each fan bracket 2 is provided with at least one vibration damper assembly 3 between itself and the fan body 1.
[0085] In other words, two, three, four, or more fan brackets 2 can be set, with at least two fan brackets 2 spaced apart to avoid interference. By setting at least two fan brackets 2, stable support can be provided for the entire fan body 1, improving the installation stability and reliability of the fan assembly 100 and making the connection between the fan assembly 100 and the working surface more secure. Each fan bracket 2 is equipped with at least one vibration damper assembly 3 between it and the fan body 1. That is, one, two, or more vibration damper assemblies 3 can be set between each fan bracket 2 and the fan body 1, thereby reducing vibration transmission between each fan body 1 and the fan bracket 2 through at least one vibration damper assembly 3, enhancing the vibration reduction effect.
[0086] Specifically, such as Figure 3 and Figure 8 As shown, two fan brackets 2 are provided, which are connected to the working surface to improve the installation stability and reliability of the fan assembly 100. The two fan brackets 2 are distributed in parallel and spaced apart, corresponding to the position of the fan mounting base 11, so that the vibration damper assembly 3 can be accurately installed between the fan bracket 2 and the fan mounting base 11 to absorb vibration.
[0087] In some embodiments, each wind turbine support 2 is provided with at least two vibration damper assemblies 3, and the at least two vibration damper assemblies 3 are spaced apart in the length direction of the wind turbine support 2.
[0088] In other words, each wind turbine support 2 can be equipped with two, three, or more vibration damping components 3 to further enhance the vibration damping effect, reduce the vibration transmission from the wind turbine body 1 to the wind turbine support 2, and reduce low-frequency resonance noise. Furthermore, at least two vibration damping components 3 are spaced apart along the length of the wind turbine support 2 to ensure a stable connection between the wind turbine body 1 and the wind turbine support 2 while enhancing the vibration damping effect.
[0089] Specifically, such as Figure 8 As shown, two fan brackets 2 are provided, and each fan bracket 2 is provided with two vibration damper assemblies 3. The two vibration damper assemblies 3 are distributed at a certain distance along the length of the fan bracket 2 to avoid interference between the two vibration damper assemblies 3, so that they can work together to reduce vibration. The fan body 1 is provided with four fan mounting seats 11 distributed at intervals. Two fan mounting seats 11 correspond to the positions of one fan bracket 2, and the other two fan mounting seats 11 correspond to the positions of the other fan bracket 2. Each fan mounting seat 11 is connected to a vibration damper assembly 3, so that the four vibration damper assemblies 3 are installed between the fan bracket 2 and the fan mounting seats 11 to reduce the vibration of the entire fan assembly 100 and enhance the vibration reduction effect.
[0090] In some embodiments, such as Figure 1 As shown, the fan assembly 100 also includes a fan 6 and an air guide ring 7. The air guide ring 7 is used to guide the airflow, so that the airflow moves along the direction of the air guide ring 7 axis until it reaches the fan 6, so that the fan 6 can better drive the airflow, form a strong airflow, and guide more gas to flow out to the outside along the axis of the air guide ring 7, thereby increasing the air volume of the fan assembly 100. Figure 1 The image shows vertical upward airflow, with the air guide ring 7 guiding the airflow upwards.
[0091] Among them, such as Figure 6 As shown, the fan 6 is rotatably mounted inside the air guide ring 7. The fan body 1 is equipped with a motor shaft 12, which is connected to the fan 6. That is to say, the fan 6 can rotate relative to the air guide ring 7 to generate a strong airflow. The fan 6 is installed inside the air guide ring 7 and spaced a certain distance from the air guide ring 7 to prevent the fan 6 from hitting the air guide ring 7 when rotating, which would cause abnormal noise or safety hazards. The motor shaft 12 is connected to the fan 6, that is, the motor shaft 12 of the drive motor is connected to the fan 6 so that when the motor shaft 12 rotates, it can drive the fan 6 to rotate, providing power for the rotation of the fan 6.
[0092] This application reduces low-frequency resonance noise at its source by installing the vibration damper assembly 3 between the fan mounting base 11 and the fan bracket 2. Simultaneously, the vibration damper assembly 3 ensures that the fan body 1 can only vibrate along the connection direction between the fan body 1 and the fan bracket 2 without tilting. Figure 1 As shown, this design ensures that the fan body 1 and fan 6 can only vibrate vertically without tilting, thus preventing the fan 6 from tilting and coming into contact with the air guide ring 7, which could cause safety hazards and improve the safety of the fan assembly 100.
[0093] In other embodiments, such as Figure 11 As shown, the shock absorber assembly also includes an end cap 313, which is installed on the upper end of the housing 31. That is, the end cap 313 is connected to the end of the housing side wall 314312 away from the bottom wall 312315 of the housing to close the housing 31. A first connecting hole 3131 can be provided on the end cap 313, and a second connecting hole 3141 can be provided on the housing 31. The connector can be sequentially inserted into the first connecting hole 3131 and the second connecting hole 3141 to achieve a fixed connection between the end cap 313 and the housing 31, thereby limiting the piston rod 32 and preventing the piston rod 32 from coming out of the housing 31.
[0094] And such as Figure 11As shown, a clearance hole 3132 can also be provided on the end cap 313 to allow the piston rod 32 to pass through the clearance hole 3132 and extend to the outside, thereby ensuring the mobility of the piston rod 32. The radial dimension of the clearance hole 3132 can be set to be larger than the outer diameter of the rod 322, so that a certain gap is formed between the clearance hole 3132 and the rod portion 322, ensuring the smooth movement of the piston rod 32.
