Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation mechanisms, in particular to a heat dissipation mechanism of a cylinder. Background Art

[0002] With the continuous improvement of computer technology and industrial automation level, chassis and cylinder, as key components, play an important role in various types of equipment; however, in actual applications, due to unreasonable heat dissipation design or the influence of environmental conditions, chassis and cylinders often face heat dissipation problems. Long-term high-load operation causes the internal temperature of the chassis to rise sharply, and the air circulation is poor, resulting in hardware performance degradation and even failures; similarly, if the heat generated by the cylinder during the inflation process cannot be effectively dissipated, it will not only cause the cylinder body to overheat, but also affect the service life of key components such as the rubber ring in the cylinder. The rubber ring in the cylinder is a key component for sealing and buffering. It is easy to be deformed and aged due to heat when working in a high temperature environment for a long time, which in turn aggravates wear, resulting in a decrease in sealing performance and even causing serious problems such as leakage. This not only affects the normal operation of the cylinder, but also may lead to a reduction in the stability and reliability of the entire system. Therefore, we propose a heat dissipation mechanism for the cylinder. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art. Due to unreasonable heat dissipation design or the influence of environmental conditions, the chassis and cylinders often face heat dissipation problems. Long-term high-load operation causes the internal temperature of the chassis to rise sharply, the air circulation is not smooth, resulting in hardware performance degradation and even failure.

[0004] Similarly, if the heat generated by the cylinder during the inflation process cannot be effectively dissipated, it will not only cause the cylinder body to overheat, but also affect the service life of key components such as the rubber ring inside the cylinder. The rubber ring inside the cylinder is a key component for sealing and buffering. It is easy to be deformed and aged due to heat when working in a high temperature environment for a long time, which will further aggravate the wear and lead to a decrease in sealing performance and even cause serious problems such as air leakage. This not only affects the normal operation of the cylinder, but may also reduce the stability and reliability of the entire system.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heat dissipation mechanism of a cylinder, comprising a box shell and a connecting bracket fixedly installed on one side, a piston assembly is installed between the box shell and the connecting bracket, the piston assembly comprises a piston sleeve, a piston, and a piston drive assembly, one end of the piston sleeve is butted with the inside of the connecting bracket, and the other end is fixed to the box shell through an integrated fixing plate, one end of the piston is movably connected to the inside of the piston sleeve, and the other end is installed in the box shell through the piston drive assembly;

[0006] The periphery of the piston sleeve is located in the connecting bracket and is sleeved with a heat dissipation aluminum sleeve. The fixing plate is corresponding to the fixing position of the box shell and is provided with a through hole around the piston. A motor is installed on the other side of the box shell. Fan blades and driving gears are installed in sequence at the output end of the motor. When the motor is started, the fan blades drive the gas to flow through the piston drive assembly, the through hole and the heat dissipation aluminum sleeve in sequence to dissipate the heat of the box and the cylinder. At the same time, the driving gear meshes with the piston drive assembly to drive the piston to reciprocate in the piston sleeve.

[0007] Furthermore, the end of the connecting bracket away from the box shell is fixed by a first sealing ring and a nut, and the outer mounting port of the connecting bracket is connected to the piston and is provided with a mounting port, through which a second sealing ring is accommodated to install the cylinder piping joint.

[0008] Furthermore, a piston rubber ring is installed at the piston sleeve end that is movably connected to the piston.

[0009] Furthermore, the box shell is provided with a window end, and a bearing installation groove is opened on a side corresponding to the window end. The bearing and the bearing sleeve are installed in sequence in the bearing installation groove, and the outer side of the box shell is connected to the bearing sleeve by rivets, and the bearing and the bearing sleeve are rotatably connected.

[0010] Furthermore, the piston drive assembly includes a driven gear disc seat, a rotating disc, and a latch. The driven gear disc on the outer periphery of the bottom of the driven gear disc seat is meshed and connected with the driving gear, and the bottom is docked with the bearing sleeve. The rotating disc is integrated with the driven gear disc seat and a piston connecting groove is opened. The latch is inserted into the piston and docked with the piston connecting groove.

[0011] Furthermore, the latch pin is positioned by sequentially installing a gasket and a retaining spring in the installation groove provided on the piston handle.

[0012] Furthermore, a cover plate is installed on the housing shell on the side of the bearing installation groove.

[0013] Furthermore, the fan blades are located in fan blade slots provided in the outer shell of the box body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. An effective heat dissipation system is formed by combining the heat dissipation aluminum sleeve, through holes, fan blades and motors. The setting of the heat dissipation aluminum sleeve increases the heat dissipation area and improves the heat dissipation efficiency. The design of the through holes allows the heat dissipation gas to flow smoothly, while the motor and fan blades can actively drive the flow of gas, thereby enhancing the heat dissipation effect. Such a design can significantly reduce the temperature of the chassis and cylinder, and avoid hardware performance degradation and failures.

[0016] 2. By effectively lowering the temperature of the cylinder body, the heat dissipation mechanism reduces the risk of thermal deformation and aging of the rubber ring in the cylinder, thereby extending the service life of the rubber ring. At the same time, it reduces the high temperature environment in the cylinder, reduces the wear of the rubber ring, improves the sealing performance of the cylinder, and reduces the probability of problems such as air leakage.

[0017] 3. Since the heat dissipation mechanism can effectively reduce the temperature of the chassis and cylinder, it can improve the stability and reliability of the entire system, avoid hardware failures and system instability caused by high temperature, and ensure the normal operation of the equipment.

[0018] 4. The fan blades and driving gears driven by the motor not only realize the heat dissipation function, but also drive the reciprocating motion of the piston in the piston sleeve through the gear meshing piston drive assembly. This design not only simplifies the structure, but also improves the energy utilization efficiency.

[0019] To sum up, the cylinder heat dissipation mechanism of the utility model has an efficient heat dissipation design, and the gas flow covers the gear transmission to the cylinder at the same time, and the gas flow from the chassis to the cylinder is cooled at the same time, which extends the service life of key components, improves the stability and reliability of the system, and has a high use value.

A motor 10 is installed on the other side of the box shell 1. A fan blade 11 and a driving gear 12 are installed in sequence at the output end of the motor 10. Starting the motor 10 allows the fan blade 11 to drive the gas flow through the piston drive assembly 6, the through hole 9 and the heat dissipation aluminum sleeve 8 in sequence to dissipate the heat of the box and the cylinder. At the same time, the driving gear 12 engages the piston drive assembly 6 to drive the piston 5 to reciprocate in the piston sleeve 4.

[0041] Example 2

[0042] like Figure 1-2 As shown, the end of the connecting bracket 2 away from the box shell 1 is fixed by a first sealing ring 201 and a nut 202, and the outer mounting port of the connecting bracket 2 is connected to the piston 5 and is provided with a mounting port 203, through which a second sealing ring 204 is accommodated to install the cylinder piping joint.

[0043] The piston 5 is movably connected to the piston sleeve 4 end and a piston rubber ring 51 is installed. The piston reciprocates in the cylinder. The piston sleeve 4 is used to guide the piston 5 to ensure that it can move smoothly on a predetermined path, and the piston rubber ring 51 is usually used for sealing to prevent gas leakage between the piston 5 and the piston sleeve 4. When the piston 5 is movably connected to the piston sleeve 4 end, it can ensure the sealing between the piston 5 and the piston sleeve 4.

[0044] The box shell 1 is provided with a window end 101, which ensures air circulation. A bearing mounting groove 102 is opened on one side corresponding to the window end 101. A bearing 103 and a bearing sleeve 104 are installed in the bearing mounting groove 102 in sequence. The outer side of the box shell 1 is connected to the bearing sleeve 104 by a rivet 105, and the bearing 103 and the bearing sleeve 104 are rotatably connected.

[0045] The piston drive assembly 6 includes a driven gear disc seat 601, a rotating disc 602, and a latch 603.

The rotating disc 602 is integrated with the driven gear disc seat 601 and a piston connecting groove 604 is opened. The latch 603 is inserted into the piston 5 and docked with the piston connecting groove 604.

[0046] The latch pin 603 is positioned by sequentially installing a gasket 502 and a retaining ring 503 in the installation groove 501 provided on the handle of the piston 5 .

[0047] A cover plate 106 is also installed on the housing shell 1 on the side of the bearing installation groove 102, and the cover plate 106 is used to fix the entire device to a fixing seat or equipment.

[0048] The fan blades 11 are located in the fan blade slots 111 opened in the box housing 1 , providing a good operating environment for the fan blades 11 .

[0049] The utility model workflow:

[0050] 1. Startup and heat dissipation:

[0051] ① Start the motor 10, which drives the fan blades 11 to rotate and generate airflow;

[0052] ② The airflow first passes through the piston drive assembly 6 to dissipate heat from the piston drive assembly 6;

[0053] ③ Then, the airflow passes through the through hole 9 on the fixed plate 7 and enters the space between the piston sleeve 4 and the heat dissipation aluminum sleeve 8 to dissipate heat from the piston sleeve 4 and the heat dissipation aluminum sleeve 8;

[0054] ④ Due to its material and structural design, the heat dissipation aluminum sleeve 8 can effectively expand the heat dissipation area and improve the heat dissipation efficiency;

[0055] ⑤ The airflow continues to flow and is eventually discharged from the box housing 1, completing the entire heat dissipation cycle.

[0056] 2. Reciprocating motion of the piston:

[0057] ① During the startup and heat dissipation process, the motor 10 drives the driving gear 12 to rotate;

[0058] ② The driving gear 12 meshes with the driven toothed disc on the driven toothed disc seat 601 of the piston driving assembly 6, thereby driving the driven toothed disc seat 601 and the rotating disc 602 to rotate;

[0059] ③ The piston connection groove 604 on the rotating disk 602 is connected with the latch 603 on the piston 5, so that the piston 5 reciprocates in the piston sleeve 4;

[0060] ④ The latch pin 603 is positioned by the gasket 502 and the retaining ring 503 in the mounting groove 501 on the handle of the piston 5 to ensure the stable movement of the piston 5;

[0061] In combination with the above: Due to the effective operation of the heat dissipation mechanism, the temperature of the chassis and the cylinder is reduced, thereby avoiding hardware performance degradation and failures. At the same time, the rubber ring in the cylinder reduces the impact of the high temperature environment, extends its service life, and improves its sealing performance. The stability and reliability of the entire system are therefore improved, ensuring the normal operation of the equipment.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
