[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0026] A cylinder guide rod structure provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0027] Embodiment 1:

[0028] Combination Figure 1-4 As shown, the utility model provides a cylinder guide rod structure, including a fixing assembly 100 and a guide assembly 200, wherein the fixing assembly 100 includes a cylinder body sleeve 110, a plurality of threaded rods 120 connected to the cylinder body sleeve 110, a bearing 130 movably sleeved on the inner end of the threaded rod 120, a T-shaped slide plate 140 sleeved on the outer side of the bearing 130, and a limit plate 150 movably connected between two T-shaped slide plates 140, wherein two limit plates 150 are provided and are located inside the cylinder body sleeve 110;

[0029] The guide assembly 200 includes a plurality of stabilizing rods 210 movably connected to the cylinder body sleeve 110, a cross plate 220 connected between the plurality of stabilizing rods 210, a cylinder piston ring 230 connected to the bottom of the cross plate 220, and a threaded second rod 240 connected to the cylinder piston ring 230.

[0030] Furthermore, multiple threaded rods 120 respectively penetrate the four surfaces of the cylinder body sleeve 110, and the threaded rod 120 and the threaded rod 240 are both arranged in a T shape. With this layout design, a limit plate 150 can be squeezed by two threaded rods 120 at the same time, and because the two threaded rods 120 on a limit plate 150 are arranged vertically, the extrusion force on the limit plate 150 is in two directions, which ensures that it can be firmly attached to the cylinder.

[0031] Furthermore, multiple stabilizer bars 210 are arranged in groups of two, and are set as two groups. The two groups of stabilizer bars 210 are vertically symmetrical about the cylinder piston ring 230. With this layout design, the movable end of the cylinder can be smoothly guided, and the probability of friction between the movable end of the cylinder and the inner wall of the cylinder body can be effectively reduced, thereby ensuring the service life of the cylinder guide rod.

[0032] Furthermore, the inner end of the threaded second rod 240 passes through the cylinder piston ring 230 and extends to the inside of the cylinder piston ring 230. With this structural design, after the inner end of the threaded second rod 240 is pressed against the outer wall of the cylinder guide rod, the cylinder piston ring 230 can be firmly sleeved on the top of the cylinder guide rod.

[0033] Embodiment 2:

[0034] Combination Figure 1-2 As shown, on the basis of the first embodiment, shallow grooves 300 are opened on the four sides of the cylinder body sleeve 110, and multiple threaded rods 120 are respectively located inside the multiple shallow grooves 300. The diameter of the shallow grooves 300 is larger than the diameter of the threaded rod 120. The shallow grooves 300 are provided so that the threaded rod 120 can be retracted into the cylinder body sleeve 110. In this way, the aesthetics of the product can be guaranteed, and the potential safety hazards caused by the abrupt setting of the threaded rod 120 can be avoided.

[0035] Embodiment three:

[0036] Combination Figure 1-2 As shown, in the above embodiment, two limit plates 150 are diagonally arranged, and the limit plates 150 are made of metal material. With this layout design, the two limit plates 150 cooperate to firmly clamp the cylinder, and also make the installation of the cylinder body sleeve 110 more secure.

[0037] The working principle and use process of the utility model are as follows: when the device is put into actual use, the cylinder to be installed is passed through the cylinder body sleeve 110, and then the multiple threaded rods 120 are tightened. The limit plate 150 is pushed and pressed against the outer wall of the cylinder by the threaded rod 120, and then the two limit plates 150 cooperate to complete the connection between the cylinder body sleeve 110 and the cylinder, and then the cylinder piston ring 230 is sleeved on the top of the movable end of the cylinder, and then the threaded rod 240 is tightened, thereby making it possible for the movable end of the cylinder to be guided by the multiple stabilizing rods 210 when it is extended and retracted, thereby reducing the friction between it and the inner wall of the cylinder body and extending its service life.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate 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 claims and their equivalents.
