Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0046] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0047] Embodiment 1:

[0048] like Figures 1 to 3 As shown, an embodiment of the present application provides a cylinder with a stable structure, including a cylinder body 1, a piston assembly 2, and also includes: a support unit 3, which is fixedly installed at the lower end of the cylinder body 1.

[0049] Furthermore, the support unit 3 includes a support plate 4, which is arranged at the lower end of the cylinder body 1; a buffer rod 5, which is fixedly connected between the support plate 4 and the cylinder body 1; and a sleeve 6, which is arranged on the support plate 4 and has the buffer rod 5 sleeved therein.

[0050] Furthermore, it also includes a mounting seat 7 and a T-shaped slot 8, which is arranged at the upper end of the mounting seat 7; wherein the support plate 4 can be slidably installed in the T-shaped slot 8.

[0051] Furthermore, it also includes a pair of limit grooves 9, which are respectively arranged on the side walls of the T-slot 8, and the limit groove 9 on one side passes through the inner wall of the T-slot 8; a limit plate 10, which is L-shaped, and the long end passes through the limit groove 9 on one side to the other side; a fastening screw 11, which fixes the short end of the limit plate 10 on one side of the mounting seat 7.

[0052] Furthermore, it also includes a pair of slide grooves 12 which are respectively arranged on both sides of the support plate 4 ; and a plurality of rollers 13 which are rotatably installed in each slide groove 12 .

[0053] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the cylinder is mounted on the support unit 3, the cylinder body 1 and the support plate 4 are directly fixedly connected by the buffer rod 5, and the connecting end of the buffer rod 5 and the support plate 4 is protected and fixed by the sleeve 6 to ensure the buffering property of the buffer rod 5. The buffer rod 5 is elastic and will shake when the cylinder is working. The shaking pressure of the cylinder is supported and offset by the elastic force generated by the buffer rod 5, thereby ensuring the stability of the cylinder when working. In order to improve the fixation of the support plate 4, the support plate 4 is installed in the T-slot 8 of the mounting seat 7, and the two sides of the support plate 4 are clamped at the two ends of the T-slot 8. When the support plate 4 needs to be fixed, the limit plate 10 is installed in the limit slot 9, and then the short end of the limit plate 10 is fixed to the mounting seat 7 by the fastening screw 11. The limit plate 10 effectively prevents the support plate 4 from moving out of the T-slot 8. When the support plate 4 needs to be removed, the fastening screw 11 is screwed out, and the limit plate 10 is pulled out, and the cylinder connected to the support plate 4 can be pushed out of the T-slot 8 together. Rollers 13 are evenly distributed in the slide groove 12 of the support plate 4. The setting of the rollers 13 makes the sliding of the support plate 4 smoother.

[0054] Embodiment 2:

[0055] like Figure 4 , Figure 5As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: the piston assembly 2 includes a piston rod 14; a piston 15; which is sleeved on the piston rod 14; a sealing ring 16, which is installed on the piston 15; a pushing assembly 17, which is fixedly installed on the top of the sealing ring 16; wherein one end of the pushing assembly 17 is close to the sealing ring 16.

[0056] Furthermore, the pushing assembly 17 includes a pressure ring 18, which is sleeved on the piston rod 14; a spring 19, which is fixedly connected between the pressure ring 18 and the piston 15; an extrusion plate 20, whose upper end is fixedly connected to the outer side of the pressure ring 18; wherein the width of the extrusion plate 20 gradually decreases from top to bottom, and its lower top end fits with the contact surface of the sealing ring 16 and the piston 15.

[0057] In this embodiment of the present application, due to the adoption of the above-mentioned structure, in order to improve the service life of the sealing ring 16 of the piston 15, a pushing assembly 17 is provided on the piston 15. When the cylinder is running, gas is supplied, and the air pressure squeezes the pressure ring 18. At the same time, the spring 19 is shortened, and the pressure ring 18 drives the extrusion plate 20 to squeeze in the direction of the sealing ring 16. The lower top end of the extrusion plate 20 is inserted between the contact surface of the sealing ring 16 and the piston 15, so that the extrusion plate 20 pushes the sealing ring 16 outward, so that the outer side of the sealing ring 16 fits with the inner wall of the cylinder body 1, thereby achieving a sealing effect, ensuring the sealing of the piston 15, and in the case of insufficient air pressure, it can also avoid friction between the sealing ring 16 and the inner wall of the cylinder body 1, thereby improving the service life of the sealing ring 16.

[0058] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element.
