Description

Technical Field

[0001] The utility model belongs to the technical field of screw removal tools, and more specifically relates to a voltage regulator screw remover. Background Art

[0002] A natural gas pressure regulator is a device that can keep the downstream pressure stable regardless of changes in gas flow and upstream pressure. A natural gas pressure regulator should be able to reduce the upstream pressure to a stable downstream pressure; when a pressure regulator fails, it should be able to limit the downstream pressure to a safe range.

[0003] In reality, the natural gas pressure regulator is ellipsoidal in shape, consisting of two parts that snap together and then fixed with screws. There is a circular groove on the edge of the top of the natural gas pressure regulator, and the nut of the screw is fixed in the circular groove when it is fixed. In actual operation, the screws used to fix the natural gas pressure regulator are mostly hexagonal screws, but the screws will rust, causing the hexagonal countersunk holes on the nuts used for disassembly and installation to become round, making it difficult to remove the screws.

[0032] The voltage regulator screw remover provided by the utility model is now described.

[0033] Please also read Figure 1 The voltage regulator screw remover comprises a guide rod 1, two clamping mechanisms 2 and two driving mechanisms 3, wherein the guide rod 1 is arranged above the screw 4 to be removed; the two clamping mechanisms 2 are slidably arranged on the guide rod 1, and the two clamping mechanisms 2 are arranged on both sides of the guide rod 1; the two driving mechanisms 3 are slidably arranged on the guide rod 1, the driving mechanisms 3 correspond to the clamping mechanisms 2 one by one, and the driving mechanisms 3 are arranged on the outer sides of the corresponding clamping mechanisms 2, and the driving mechanisms 3 are used to drive the clamping mechanisms 2 to move toward the screw 4 to be removed, and enable the two clamping mechanisms 2 to clamp and fix the screw 4 to be removed.

[0034] The beneficial effect of the voltage regulator screw remover provided in the present embodiment is as follows: compared with the prior art, the voltage regulator screw remover provided in the present embodiment is provided with a guide rod 1, a clamping mechanism 2 and a driving mechanism 3. When in use, the guide rod 1 is placed in the circular groove, and the clamping mechanism 2 is driven by the driving mechanism 3 to clamp the nut of the screw 4. At this time, the screw 4 cannot rotate, and then a wrench or other tools are used to unscrew the nut at the bottom of the screw 4, so that the rusted screw 4 can be removed, which greatly reduces the difficulty of removing the rusted screw 4.

[0035] like Figure 2 As shown, the clamping mechanism 2 includes a sliding ring 201 and a clamping block 202. The sliding ring 201 is annular and sleeved on the guide rod 1. The clamping block 202 is arranged on the end surface of the sliding ring 201. The clamping block 202 has a rough surface. When the two clamping mechanisms 2 clamp the screw 4, the rough surface is pressed against the screw 4. The provision of the rough surface can increase the friction between the clamping block and the nut of the screw 4, thereby facilitating the fixing of the screw 4.

[0036] As a preferred technical solution, the clamping block 202 includes a connecting block 203 and a plurality of clamping teeth 204 provided at one end of the connecting block 203, and the end surface of the connecting block 203 provided with the clamping teeth 204 constitutes a rough surface. The clamping teeth 204 are welded and fixed on the connecting block 203, and the arrangement of the clamping teeth 204 is simple in structure and convenient to use.

[0037] like Figure 1As shown, the driving mechanism 3 includes a locking member 301 and a gasket 302. The inner wall of the locking member 301 is provided with a first thread, and the side wall of the guide rod 1 is provided with a second thread. The first thread and the second thread are adapted to each other. The locking member 301 is screwed on the guide rod 1. The gasket 302 is annular and clamped between the locking member 301 and the sliding ring 201. As the locking member 301 rotates, the locking member 301 rotates along the axial direction of the guide rod 1, thereby causing the locking member 301 to move on the guide rod 1, and also facilitates pushing the clamping mechanism 2 to move toward the middle to clamp the nut of the screw 4.

[0038] Combination Figure 3 and Figure 4 As shown, the locking member 301 includes a locking ring 303, a driving ring and a locking assembly. The locking ring 303 is screwed on the guide rod 1. The locking ring 303 is provided with a mounting groove 305. The driving ring is arranged in the mounting groove 305. The driving ring is provided with a holding tube 306. The locking assembly is arranged between the locking ring 303 and the driving ring. When the locking assembly is unlocked, the driving ring can rotate relative to the locking ring 303; and when the locking assembly is locked, the driving ring is fixed relative to the locking ring 303. Due to the narrow space in the top groove of the voltage regulator, it is not convenient to use existing tools to rotate the locking member 301. The locking ring 303, the driving ring and the locking assembly are arranged such that, when in use, the holding tube 306 is held and the locking assembly is locked. At this time, the driving ring and the locking ring 303 are fixed. At this time, the locking ring 303 can be driven to rotate by flipping the holding tube 306. After the holding tube 306 is interfered by the voltage regulator, the components of the locking assembly are released. At this time, the driving ring can rotate relative to the locking ring 303. At this time, the holding tube 306 is flipped in the opposite direction to create a flipping space for the holding tube 306. Repeating the above steps can move the locking ring 303 along the guide rod 1.

[0039] like Figure 5 and Figure 6As shown, the locking assembly includes a plurality of first fixing holes 307, a second fixing hole, a first clamping rod 308, two second clamping rods 309 and a third fixing hole 310. The first fixing hole 307 is arranged on the locking ring 303, and the axis of the first fixing hole 307 is parallel to the axis of the locking ring 303. The second fixing hole is arranged on the driving ring, and the axis of the second fixing hole is parallel to the axis of the driving ring. The second fixing hole can be connected with different first fixing holes 307 due to the rotation of the driving ring. The holding tube 306 is in communication with the third fixing hole 310, the third fixing hole 310 is in communication with the second fixing hole, the axis of the third fixing hole 310 is perpendicular to the axis of the second fixing hole, the second clamping rod 309 is slidably disposed in the second fixing hole, the first clamping rod 308 is inserted in the holding tube 306, in the initial state, a part of the first clamping rod 308 extends out of the holding tube 306, one end of the second clamping rod 309 is inserted in the third fixing hole 310, and the other end of the second clamping rod 309 is disposed in the second fixing hole, at which time the driving ring can rotate relative to the locking ring 303. Under the action of external force, when the first clamping rod 308 is fully inserted into the holding tube 306, the first clamping rod 308 pushes a part of the second clamping rod 309 to extend into the first fixing hole 307, at which time the driving ring is fixed relative to the locking ring 303.

[0040] In this embodiment, a first driving block 311 is provided on the side wall of the first clamping rod 308, a first driving groove 312 is provided on one side of the third fixing hole 310, the first driving block 311 is slidably disposed in the first driving groove 312, a first spring 313 is provided between the first driving block 311 and the first driving groove 312, and when the first spring 313 is in a natural state, a part of the first clamping rod 308 is disposed outside the holding tube 306. The arrangement of the first driving block 311, the first driving groove 312 and the first spring 313 enables the first clamping rod 308 to be reset when external force driving is lost.

[0041] In addition, a second driving block 314 is provided on the side wall of the second clamping rod 309, a second driving groove 315 is provided on one side of the second fixing hole, the second driving block 314 is slidably arranged in the second driving groove 315, a second spring 316 is provided between the second driving block 314 and the second driving groove 315, and when the second spring 316 is in a natural state, a part of the second clamping rod 309 is arranged in the third fixing hole 310. The arrangement of the second driving block 314, the second driving groove 315 and the second spring 316 enables the second clamping rod 309 to be reset when the drive of the first clamping rod 308 is lost.

[0042] Finally, the bottom end of the first clamping rod 308 is set to be tapered, so that the first clamping rod 308 can be inserted between the two second clamping rods 309, so that the first clamping rod 308 can push the second clamping rod 309 to move.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
