Description

Technical Field

[0001] The utility model relates to the technical field of virtual reality glasses, in particular to an oil cylinder capable of bearing radial force. Background Art

[0002] As the actuator in the hydraulic transmission system, the hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic cylinder can realize reciprocating linear motion and is a widely used power supply structure.

[0003] The existing hydraulic cylinders have the following disadvantages when in use: the traditional cylinder structure, due to the complex actual working conditions, the hydraulic cylinder often also bears radial force, so that the force is not centered. When it is subjected to radial force, the end cover and piston of the cylinder will be stressed to resist the radial force. Since there are seals on the end cover and piston, the seals will be damaged by pressure, reducing their service life. For this reason, we propose a cylinder that can withstand radial force. Summary of the Invention

[0004] The main purpose of this utility model is to provide a cylinder that can withstand radial force, which can transfer the radial force it withstands to the cylinder rod of the large cylinder during use, thereby protecting the seal of the internal small cylinder and extending the service life of the cylinder, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A cylinder capable of withstanding radial force comprises a large cylinder barrel, a large cylinder body and a small cylinder barrel, the power output end of the large cylinder body being cooperatively connected to the large cylinder body, a cylinder support being provided inside the large cylinder body, a small cylinder barrel being installed at one end of the large cylinder barrel away from the large cylinder body, a small cylinder barrel being cooperatively connected to the power output end of the small cylinder barrel, a pin A being installed at the end of the small cylinder piston rod and being connected to the cylinder support through the pin A, a wear-resistant bushing being installed at the connection between the inner wall of the large cylinder barrel and the outer wall of the large cylinder barrel.

[0007] Furthermore, the end of the large cylinder barrel is detachably connected to a fixing seat, and the fixing seat is installed with a pin shaft B at one end facing the inside of the large cylinder barrel and is connected to the end of the small cylinder barrel through the pin shaft B; the fixing seat is located at the end of the large cylinder barrel to play a sealing role, and is connected to the small cylinder barrel through the pin shaft B to fix its installation position.

[0008] Furthermore, an observation window cover is embedded in one side of the surface of the large oil cylinder barrel; the observation window cover can be used to install and check the working status of the small oil cylinder piston rod.

[0009] Furthermore, a large cylinder side fixing flange is detachably connected to one side of the surface of the large cylinder barrel, and a large cylinder bottom fixing flange is detachably connected to the end of the large cylinder barrel away from the large cylinder body; the large cylinder side fixing flange and the large cylinder bottom fixing flange can be used to fix the overall structure of the cylinder that can withstand radial force.

[0010] Compared with the prior art, the present invention has the following beneficial effects: when the power end of the cylinder capable of withstanding radial force needs to extend, hydraulic oil enters one end of the inner barrel of the small cylinder, causing the piston rod of the small cylinder to extend, and driving the cylinder body of the large cylinder to extend to the outer peripheral position of the cylinder barrel of the large cylinder through the cylinder support. When the power end of the cylinder capable of withstanding radial force needs to retract, hydraulic oil enters the other end of the inner barrel of the small cylinder, causing the piston rod of the small cylinder to retract, and driving the cylinder body of the large cylinder to retract through the cylinder support. When the cylinder capable of withstanding radial force is subjected to radial force, the cylinder rod of the large cylinder is designed to be an anti-deformation structure. The radial force is shared by the contact surfaces of the cylinder rod, wear-resistant bushing and cylinder barrel of the large cylinder, thereby preventing the internal small cylinder from being damaged by the radial force, thereby extending the service life of the entire cylinder. The cross-sections of the cylinder body, wear-resistant bushing and cylinder barrel of the large cylinder can also be set to circular, triangular or polygonal structures as needed. The end of the cylinder body of the large cylinder is used to connect to the load, and can also be replaced with a flat or flange structure to connect the load according to different usage requirements.

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0015] like Figure 1-2As shown, a cylinder that can withstand radial force includes a large cylinder barrel 3, a large cylinder body 1 and a small cylinder barrel 6. The power output end of the large cylinder body 1 is connected to the large cylinder body 1, and a cylinder support 11 is arranged inside the large cylinder body 1. A small cylinder barrel 6 is installed at one end of the large cylinder barrel 3 away from the large cylinder body 1, and the power output end of the small cylinder barrel 6 is connected to the small cylinder piston rod 5. A pin A8 is installed at the end of the small cylinder piston rod 5 and is connected to the cylinder support 11 through the pin A8. A wear-resistant bushing 2 is installed at the connection between the inner wall of the large cylinder barrel 3 and the outer wall of the large cylinder body 1.

[0016] Among them, the end of the large cylinder barrel 3 is detachably connected to a fixing seat 7, and the fixing seat 7 is installed with a pin shaft B9 at one end facing the inside of the large cylinder barrel 3 and is connected to the end of the small cylinder barrel 6 through the pin shaft B9. An observation window cover 4 is embedded in one side of the surface of the large cylinder barrel 3; the fixing seat 7 is located at the end of the large cylinder barrel 3 to play a sealing role, and is connected to the small cylinder barrel 6 through the pin shaft B9 to fix its installation position. The observation window cover 4 can be used to install and check the working status of the small cylinder piston rod 5.

[0017] Among them, one side of the surface of the large cylinder barrel 3 is detachably connected to a large cylinder side fixing flange 31, and the end of the large cylinder barrel 3 away from the large cylinder body 1 is detachably connected to a large cylinder bottom fixing flange 32; the large cylinder side fixing flange 31 and the large cylinder bottom fixing flange 32 can be used to fix the overall structure of the cylinder that can withstand radial force.

[0018] It should be noted that the present invention is a kind of oil cylinder that can withstand radial force. When in use, when the power end of the oil cylinder that can withstand radial force needs to extend, hydraulic oil enters one end of the inner barrel of the small oil cylinder 6, so that the piston rod 5 of the small oil cylinder extends, and drives the cylinder body 1 of the large oil cylinder to extend to the outer peripheral position of the cylinder barrel 3 of the large oil cylinder through the cylinder support 11. When the power end of the oil cylinder that can withstand radial force needs to retract, hydraulic oil enters the other end of the inner barrel of the small oil cylinder 6, so that the piston rod 5 of the small oil cylinder retracts, and drives the cylinder body 1 of the large oil cylinder to retract through the cylinder support 11. When the oil cylinder is subjected to radial force, the large cylinder rod is designed as an anti-deformation structure. The radial force is shared through the contact surface cooperation of the large cylinder rod, wear-resistant bushing 2, and large cylinder barrel 3 to avoid damage to the internal small cylinder due to radial force, thereby extending the service life of the entire oil cylinder. The cross-section of the large cylinder body 1, wear-resistant bushing 2, and large cylinder barrel 3 can also be set to a circular, triangular or polygonal structure as needed. The end of the large cylinder body 1 is used to connect to the load, and can also be replaced with a flat or flange structure to connect the load according to different usage requirements.
