[0002] Glyd ring, also known as Glyd seal ring, is a commonly used sealing element. Glyd rings can be divided into Glyd rings for holes and Glyd rings for shafts. They play an important role in the sealing system of equipment such as oil cylinders and hydraulic motors. In addition, Glyd rings can work stably in a variety of industrial environments due to their high temperature resistance, oil resistance, wear resistance, and corrosion resistance. Glyd rings are widely used in various hydraulic and pneumatic systems, playing an important role in ensuring the normal operation of equipment and improving the performance of equipment.

[0003] In the prior art, since the inner diameter of the grid ring of the oil cylinder and the cylinder piston is much smaller than the outer diameter of the piston, and the material of the grid ring is relatively hard, it cannot be opened during installation, that is, it needs to be pried with the help of tools to install it during installation. Conventional installation tools and methods are laborious and inefficient, and there are problems such as difficulty in installation and long time consumption, which not only affects work efficiency, but also may cause a decrease in sealing performance due to improper installation, and even cause equipment failure.

[0004] Therefore, there is a need for a Gly ring for an oil cylinder or air cylinder piston that is easy to install, so as to solve the problem that the Gly ring in the prior art is laborious and inefficient to install. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] See also Figure 1-4 The utility model provides an oil cylinder piston grid ring that is easy to install, including a piston 1, a guide mechanism 2, a grid ring 3 and a pressing mechanism 4, the guide mechanism 2 is arranged above the piston 1, the grid ring 3 is arranged outside the guide mechanism 2, and the pressing mechanism 4 is arranged above the grid ring 3.

[0025] The guide mechanism 2 consists of a conical cylinder 201, an upper cylindrical cylinder 202, a guide strip 203 and a lower cylindrical cylinder 204. The conical cylinder 201 is sleeved on the outside of the piston 1, the upper cylindrical cylinder 202 is fixedly connected to the top of the conical cylinder 201, and the lower cylindrical cylinder 204 is fixedly connected to the bottom of the conical cylinder 201.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the inner diameter of the lower cylindrical tube 204 is the same as the outer diameter of the piston 1, the inner diameters of the conical tube 201 and the upper cylindrical tube 202 are the same, and the inner diameter is larger than the diameter of the piston rod of the piston 1, and the guide strips 203 are symmetrically fixedly connected to the outside of the upper cylindrical tube 202, and there are four guide strips 203, which are symmetrically arranged according to the center of the circle of the upper cylindrical tube 202.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the pressing mechanism 4 consists of a pressing cylinder 401, a pushing cylinder 402, a fixing ring 403, a spring 405, a movable plate 406 and a slider 407. The pressing cylinder 401 is sleeved on the outside of the upper cylindrical cylinder 202, the pushing cylinder 402 is fixedly connected to the bottom of the pressing cylinder 401, the fixing ring 403 is fixedly connected to the middle part of the inner wall of the pressing cylinder 401, the spring 405 is fixedly connected to the top surface of the inner wall of the pressing cylinder 401, and the movable plate 406 is fixedly connected to the bottom of the spring 405.

[0028] According to the above working process, it can be known that: through the provided pressing cylinder 401, pushing cylinder 402 and guiding mechanism 2, the grid ring 3 sleeved on the outside of the conical cylinder 201 can be quickly installed inside the annular groove of the piston 1 without the aid of external tools, thus saving time and effort and improving assembly efficiency.

[0029] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that the push tube 402 is made of elastic plastic, the upper end of the push tube 402 is an arc structure, one end of the push tube 402 has a plurality of gaps arranged at intervals, so as to divide the one end of the push tube 402 into a plurality of petals, and one end of the push tube 402 can be slidably sleeved on the conical tube 201;

[0030] In order to prevent the pushing cylinder 402 from breaking at the connection position with the pressing cylinder 401 when being pressed, the upper end of the pushing cylinder 402 is set to a concave arc groove. The concave arc groove can reduce the pressing force and increase the flexibility of the pushing cylinder 402. It can spread out when pressed down and automatically shrink back to its original shape when released.

[0031] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that the inner wall of the fixing ring 403 is provided with a guide groove 404 adapted to the guide strip 203;

[0032] The guide strip 203 is slidably connected to the inside of the guide groove 404 to guide the pressing of the pressing cylinder 401, and the pushing cylinder 402 is driven to move downward more stably, thereby improving the practicality of the structure.

[0033] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that the slider 407 is symmetrically fixedly connected to the outside of the moving plate 406, and a slide groove adapted to the slider 407 is opened on the inner wall of the pressing cylinder 401;

[0034] The slider 407 is provided to slide inside the slide slot, thereby ensuring the stability of the upward and downward movement of the movable plate 406 and ensuring the linear movement of the spring 405.

[0035] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that an annular groove is arranged below the piston 1, and the Gly ring 3 is adapted to the size of the annular groove.

[0036] The present solution has the following working process: when in use, the conical cylinder 201 is sleeved on the outside of the piston 1, at which time the lower cylindrical cylinder 204 is sleeved above the annular groove of the piston 1, and then the grid ring 3 is sleeved on the outside of the conical cylinder 201, and then the pressing mechanism 4 is sleeved on the outside of the guide mechanism 2, and the pressing cylinder 401 is rotated to drive the internal guide groove 404 to rotate, align with the guide strip 203, press the pressing cylinder 401 downward, and push the grid ring 3 downward through the pushing cylinder 402, and when pressing downward, the surface of the grid ring 3 that presses and contacts can be moved along the conical cylinder 2 01 changes in the taper and changes in the size of the inner diameter until the grid ring 3 slides along the lower cylindrical tube 204 to the inside of the annular groove of the piston 1, completing the assembly of the grid ring 3; at this time, the upper cylindrical tube 202 pushes the movable plate 406 upward, causing the spring 405 to be squeezed. When the pressing tube 401 is released, the elastic action of the internal spring 405 will drive the movable plate 406 to reset, and at the same time drive the pressing tube 401 to move upward, so that the pushing tube 402 is separated from the outside of the conical tube 201 and restored. There is no need to manually pull out the pressing mechanism 4 upward, saving time and effort.

[0037] In summary: through the set pressing cylinder 401, the pushing cylinder 402 and the guiding mechanism 2, the grid ring 3 sleeved on the outside of the conical cylinder 201 can be quickly installed in the annular groove of the piston 1 without the aid of external tools, thus saving time and effort and improving assembly efficiency; through the set pressing mechanism 4, after the assembly of the grid ring 3 is completed, the pressing cylinder 401 is driven to move upward under the elastic action of the spring 405, so that the pushing cylinder 402 is separated from the outside of the conical cylinder 201 and restored, and there is no need to manually pull out the pressing mechanism 4 upward, which is convenient for next use and further improves work efficiency.
