[0002] In modern society, the application of lifting devices is becoming more and more widespread in many fields. Whether it is industrial production, construction, medical equipment, or office environment, lifting devices are often needed to adjust the height of equipment to meet various needs. With the continuous development and advancement of science and technology, people's requirements for lifting devices are also getting higher and higher.

[0003] For example, Chinese patent CN201120081150.1 discloses a pneumatic lifting mast, which is retracted to the bottom when not going out to perform a mission. When it needs to be taken out to perform a mission, compressed air is used as a power source to raise the pneumatic lifting mast to the required height for lighting, communication transmission, and camera lighting tasks.

[0004] However, traditional lifting devices are often composed of multiple components, making the overall structure cumbersome and difficult to maintain. In addition, operating these devices usually requires certain skills and experience, and is prone to misoperation. They are also prone to shaking and tilting during the lifting process, and the lifting speed is slow, resulting in low work efficiency and unable to meet the needs of fast lifting.

[0005] Based on this, the utility model designs a pneumatic lifting rod structure to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a pneumatic lifting rod structure to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a pneumatic lifting rod structure, including a pneumatic assembly, which consists of a fixed base, an outer rod, a piston and a piston rod. The top of the fixed base is fixedly connected to the outer rod, and the piston and the piston rod are matched and slidably connected inside the outer rod. The bottom of the piston is fixedly connected to the piston rod, and a lifting rod assembly is matched inside the outer rod and connected to the piston rod through the piston. The lifting rod assembly includes two inner rods and a pitch adjustment ring, and the tops of the two inner rods are matched with pitch adjustment rings. An air inlet is provided on the front side of the fixed base, a manual air release valve is connected to the left side of the fixed base, a slingshot power cord is connected to the right side of the fixed base, and an air pressure safety valve is connected to the rear side of the fixed base.

[0009] Preferably, the two inner rods are coaxially arranged, and the top inner rod is matched and slidably connected to the inner wall of the outer rod, and the top inner rod is matched and slidably connected to the inner wall of the bottom inner rod. Sealing rings are embedded in the outer walls of the bottoms of the two inner rods, and the pitch adjustment ring is threadedly connected to the top of the inner rod.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0014] 1. The utility model consists of a pneumatic component, a sealing ring, an air inlet and an air pressure safety valve, a manual pressure relief valve, etc. By controlling the switch of the air inlet, compressed air enters the pneumatic component, pushing the piston and piston rod to move upward, thereby driving the lifting rod assembly to the required height.

The lifting and lowering is controlled by the air source, which is easy to operate and does not require manual operation. The piston and sealing ring are used for sealing, with good sealing and high stability. The power is provided by the air source, and the lifting speed is fast, which can meet the needs of fast lifting.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figure 1 - Figure 4 Describe embodiment 1. The figure shows a pneumatic lifting rod structure, a pneumatic assembly 1, and the pneumatic assembly 1 consists of a fixed base 2, an outer rod 3, a piston 4 and a piston rod 5. The top of the fixed base 2 is fixedly connected to the outer rod 3, and the piston 4 and the piston rod 5 are matched and slidably connected inside the outer rod 3. The bottom of the piston 4 is fixedly connected to the piston rod 5. A lifting rod assembly 6 is matched inside the outer rod 3 and is connected to the piston rod 5 through the piston 4. The lifting rod assembly 6 includes two inner rods 601 and a pitch adjustment ring 602. The tops of the two inner rods 601 are matched with pitch adjustment rings 602. An air inlet 7 is opened on the front side of the fixed base 2, a manual air release valve 8 is connected to the left side of the fixed base 2, a slingshot power cord 9 is connected to the right side of the fixed base 2, and an air pressure safety valve 10 is connected to the rear side of the fixed base 2;

[0026] See also Figure 3 and Figure 4The air inlet 7 shown in the figure is connected to the inside of the pneumatic component 1 for providing compressed air to the pneumatic component 1. The left end of the slingshot power line 9 extends to the inside of the outer rod 3, and the right end of the slingshot power line 9 passes through and extends to the outside of the fixed base 2.

[0027] In this embodiment, when the lifting rod assembly 6 is needed, compressed air enters the pneumatic assembly 1 by controlling the switch of the air inlet 7, pushing the piston 4 and the piston rod 5 upward, thereby driving the lifting rod assembly 6 to rise to the required height. When the lifting rod assembly 6 needs to be lowered, the manual air relief valve 8 is opened to release the compressed air in the pneumatic assembly 1, and the piston 4 and the piston rod 5 descend under the action of gravity, so that the lifting rod assembly 6 returns to its initial position. The slingshot power cord 9 is used to connect an external power supply to provide the necessary power support for the pneumatic lifting rod structure. The air pressure safety valve 10 is used to automatically release pressure when the air pressure is too high to ensure the safe use of the pneumatic lifting rod structure. The pneumatic lifting rod structure of the utility model is not only easy to operate, but also has good stability and the ability to lift and lower quickly, which greatly improves the efficiency and safety of the lifting device.

[0028] Specifically, the outer rod 3 is connected to the fixed base 2 to form a closed pneumatic chamber. The air inlet 7 is used to connect to an external air source. The manual air relief valve 8 automatically opens when the internal pressure of the pneumatic lifting rod structure exceeds the set value to release excess gas, ensuring the safe and stable operation of the lifting rod assembly 6. The air pressure safety valve 10 is used to automatically release pressure when the air pressure is too high to protect the lifting rod structure from damage. The pneumatic lifting rod structure of the utility model not only simplifies the operating process and improves the lifting speed, but also enhances the stability and safety of the lifting rod through the setting of the air pressure safety valve 10 and the manual air relief valve 8, meeting the high requirements of modern lifting devices.

[0029] Example 2

[0030] See also Figure 5 and Figure 6 Example 2 is described. This embodiment further illustrates Example 1. In the figure, two inner rods 601 are coaxially arranged, and the top inner rod 601 is matched and slidably connected to the inner wall of the outer rod 3, and the top inner rod 601 is matched and slidably connected to the inner wall of the bottom inner rod 601. A sealing ring 11 is embedded in the outer wall of the bottom of the two inner rods 601, and a pitch adjustment ring 602 is threadedly connected to the top of the inner rod 601.

[0031] Furthermore, a pitch adjustment ring 602 is fixedly connected to the top end of the outer rod 3 , and a sealing ring 11 is embedded in the outer side wall of the bottom end of the piston rod 5 .

[0032] In this embodiment, the piston 4 is connected to the piston rod 5, and the piston rod 5 passes through the top of the pneumatic cylinder and extends into the outer rod 3. When compressed air enters the pneumatic chamber through the air inlet 7, the piston 4 is subjected to pressure, pushing the piston rod 5 to move upward, thereby driving the two inner rods 601 in the lifting rod assembly 6 to rise at the same time, realizing rapid lifting and lowering. The threaded structure design of the pitch adjustment ring 602 allows the user to adjust the height of the lifting rod assembly 6 according to actual needs to adapt to different usage scenarios.

[0033] It should be noted that the sealing ring 11 provided at the bottom of the inner rod 601 is used to ensure the sealing between the two inner rods 601 and the sealing between the bottom inner rod 601 and the outer rod 3. The sealing ring 11 provided on the piston rod 5 is used to ensure the sealing between the piston rod 5 and the inner rod 601 to prevent gas leakage, thereby improving the lifting stability and service life of the lifting rod.

[0034] Example 3

[0035] See also Figure 2 and Figure 3 Example 3 is described. This embodiment further illustrates Example 2. In the figure, a flange 12 is fixedly connected to the outer wall of the outer rod 3, and the flange 12 is connected by bolts.

[0036] Furthermore, the top of the piston 4 is fixedly connected with a flange 2 13, which is connected by bolts;

[0037] In this embodiment, the flange 12 connected to the side wall of the outer rod 3 can provide additional support to the outer rod 3, enhance the stability of the structure, and enable the lifting rod structure to maintain good rigidity when bearing a large load, thereby avoiding deformation that affects the normal operation of the lifting rod assembly 6. The connection between the flange 2 13 and the piston 4 ensures the stability and guidance of the piston 4 when moving in the pneumatic chamber, thereby ensuring the precise lifting and lowering of the lifting rod assembly 6, and facilitating the connection of the output end of the lifting structure with the lifted equipment.

[0038] It should be noted that the bolt connection between flange 12 and flange 2 13 facilitates maintenance and replacement, thereby improving the operability and service life of the lifting rod structure.
