[0031] The voltage regulator maintenance tool provided by the utility model is now described.

[0032] Please also refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the voltage regulator maintenance tool includes a sleeve 1, a plurality of blocks 2, a locking device and an operating rod 4, wherein a plurality of slide grooves 101 are evenly arranged on the inner wall of the sleeve 1, and the slide grooves 101 are arranged along the radial direction of the sleeve 1; the blocks 2 correspond to the slide grooves 101 one by one, and the blocks 2 are slidably arranged in the corresponding slide grooves 101, and a part of the blocks 2 is arranged in the inner cavity of the sleeve 1; the locking device is arranged in the side wall of the sleeve 1, and the locking device is connected to the block 2. The locking device is used to drive the block 2 to extend or retract the slide groove 101, and lock the block 2 after the sliding is completed; the operating rod 4 is connected to the sleeve 1, and the operating rod 4 is coaxially arranged with the sleeve 1.

[0033] The beneficial effect of the pressure regulator maintenance tool provided in this embodiment is: compared with the prior art, the pressure regulator maintenance tool provided in this embodiment is provided with a slide groove 101 and a block 2, and the block 2 is extended or retracted into the slide groove 101 through a locking device, so that the block 2 can clamp different bolts and then rotate different bolts, thereby reducing the number of tools used in the maintenance process of the gas pressure regulator and simplifying the maintenance complexity.

[0034] In this embodiment, an adjusting member 104 is provided on the top of the sleeve. The adjusting member 104 is in a regular hexagonal shape and is used to adjust the gas pressure regulating valve.

[0035] like Figure 4 and Figure 5As shown, the locking device includes a driving chamber 301, a driving fluid 303, a piston 3, and a driving assembly 305. The driving chamber 301 is provided on the side wall of the sleeve 1, and the driving chamber 301 is in communication with each chute 101. The piston 3 is slidably provided in the driving chamber 301. The driving fluid 303 is filled between the piston 3 and the clamping block 2. The driving assembly 305 is connected to the piston 3, and a portion of the driving assembly 305 extends out of the sleeve 1. During use, the driving assembly 305 drives the piston 3 downward, at which time the pressure of the driving fluid 303 increases, and the clamping block 2 slides outward of the chute 101. At this time, the clamping block 2 can clamp a smaller bolt or nut. Conversely, the driving assembly 305 drives the piston 3 upward, at which time the pressure of the driving fluid 303 decreases, and the clamping block 2 slides into the chute 101. At this time, the clamping block 2 can clamp a larger bolt or nut.

[0036] In this embodiment, the drive chamber 301 is annular and is equipped with multiple partitions 306, which are evenly spaced and divide the drive chamber 301 into multiple drive sub-cavities 302. Each drive sub-cavity 302 corresponds to a chute 101 and is in communication with the corresponding chute 101. The piston 3 includes multiple sub-plugs 304, which correspond to each drive sub-cavity 302 and slide within the corresponding drive sub-cavity 302. Specifically, there are six drive sub-cavities 302, six chute 101, and six clamping blocks 2, respectively, to facilitate the tightening of commonly used hexagonal bolts or hexagonal nuts. The arrangement of the drive sub-cavities 302 and the sub-plugs 304 ensures that each clamping block 2 is subjected to the same force and can move the same distance.

[0037] like Figure 1 and Figure 5 As shown, the drive assembly 305 includes a telescopic chamber 307, multiple drive rods 308, a drive disk 309, and a telescopic rod 310. The drive rods 308 correspond one-to-one with the sub-plugs 304. One end of the drive rod 308 is connected to the corresponding sub-plug 304, and the other end of the drive rod 308 is connected to the drive disk 309. The telescopic chamber 307 is located at the top of the drive chamber 301, and the drive disk 309 is located within the telescopic chamber 307. One end of the telescopic rod 310 is connected to the drive disk 309, and the other end of the telescopic rod 310 extends outside the sleeve 1. The arrangement of the drive disk 309 and the drive rod 308 enables the telescopic rod 310 to simultaneously drive multiple sub-plugs 304 to slide.

[0038] Specifically, the telescopic rod 310 is a threaded rod, and the operating rod 4 is a threaded tube. The telescopic rod 310 is threadedly connected to the operating rod 4. One end of the telescopic rod 310 is rotatably mounted on the drive disk 309, and the other end of the telescopic rod 310 extends outside the operating rod 4. The arrangement of the threaded rod and the threaded tube allows the drive disk 309 to move up and down by rotating the threaded rod. When the threaded rod is not rotating, the drive rod 308 is fixed relative to the cylinder body, thereby locking the clamping block 2.

[0039] As a preferred technical solution, a sealing groove is provided on the side wall of the chute 101, and a sealing ring 102 is provided in the sealing groove. A portion of the sealing ring 102 extends out of the sealing groove, and the clamping block is tightly pressed against the sealing ring 102. The provision of the sealing ring 102 improves the sealing between the clamping block 2 and the chute 101.

[0040] In this embodiment, the end of the telescopic rod 310 extending to the operating rod 4 is provided with a first handle 311 to facilitate rotation of the telescopic rod 310. Relative to the end connected to the sleeve 1, the other end of the operating rod 4 is provided with a second handle 401 to facilitate rotation of the operating rod 4.

[0041] Finally, a gripping ring 103 is rotatably provided on the outer wall of the sleeve 1. When in use, the cylinder body can be straightened by simply holding the gripping ring 103. If the sleeve 1 is held directly, excessive force will make it difficult to rotate the sleeve 1, and insufficient force will cause the sleeve 1 to detach from the bolt or nut.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
