Description

Technical Field

[0001] The utility model relates to the technical field of steel cylinder manipulators, in particular to an explosion-proof steel cylinder manipulator with a novel clutch structure. Background Art

[0002] The valve is a control component in the fluid delivery system. The valve is equipped with an opening and closing element for cutting off or connecting the medium. The opening and closing element is usually used in conjunction with a handwheel to open or close the valve. For example, the valve used in a gas cylinder is equipped with a handwheel, which can be turned manually to open or close the gas cylinder valve. Therefore, if you want to achieve automatic control of the valve, you need to clamp the handwheel and drive the handwheel to rotate to open or close the valve.

[0003] The remote control of the valve controller currently on the market is to drive the control component to rotate through a clutch, thereby controlling the rotation of the valve below to achieve the open / closed operating state; however, the existing clutch is not strong enough when controlling the transmission, so that it cannot respond quickly when controlling the valve rotation, and cannot close / open the valve in time, which causes an impact during use.

[0004] In addition, the bottle body of the existing liquid-filled bottle is made of glass or plastic. Although it has good sealing performance, it is easy to break the bottle body when it is hit, causing the liquid stored inside to leak, causing the liquid to leak into the user's bag, pocket or on the desktop, thereby causing pollution.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

Among them, the steel cylinder manipulator 200 includes an explosion-proof box body 210, a control component 220, a rotation prevention component 230, and a driving component 240. By arranging the control component 220 at the inner upper end of the explosion-proof box body 210 and making the upper end of the control component 220 extend upward through the explosion-proof box body 210 from bottom to top, the lower end of the control component 220 is sleeved on the valve body 100 to control the valve body 100 to rotate by screwing. Then, the driving component 240 is arranged in the explosion-proof box body 210 and the driving component 240 is located on one side of the control component 220. Among them, the driving component 240 includes a motor 241 and a clutch component 242. By arranging the clutch component 242 between the motor 241 and the control component 220, the motor 241 drives the clutch component 242 to rotate, and then controls to drive the control component 220 to rotate by screwing, so as to realize the opening / closing of the control valve body 100. Then, the rotation prevention component 230 is arranged at the inner lower side end of the explosion-proof box body 210 and is used to be fixed on the valve body 100 of the steel cylinder for locking and stabilizing to prevent it from loosening during the screwing process.

[0036] In this embodiment, the explosion-proof box body 210 includes a lower shell 211 and an upper cover 212. An inner cavity 213 is provided in the lower shell 211. Through holes 214 for the control component 220 to pass through in the middle are provided in both the lower shell 211 and the upper cover 212. A first sealing ring 300 is provided between the lower shell 211 and the upper cover 212. A limiting groove 215 is provided on the upper inner end surface of the upper cover 212. The first sealing ring 300 is arranged in the limiting groove 215, and the upper end of the lower shell 211 is clamped into the limiting groove 215 and then abuts against the end surface of the first sealing ring 300, so that a sealed state is formed inside the explosion-proof box body 210.

[0037] In this embodiment, the control component 220 includes a handwheel member 221, a handwheel fixing member 222 and a connecting shaft 223. The connecting shaft 223 passes through the through holes 214 of the upper cover 212 and the lower shell 211. Its upper end is connected to the handwheel member 221, and its lower end is connected to the handwheel fixing member 222, so that the handwheel fixing member 222 is arranged on the valve body 100 to limit and clamp the valve body 100 for screwing and rotating. And the handwheel member 221 located above is convenient for the user to screw and rotate, so as to drive the handwheel fixing member 222 at the lower end to screw and rotate the valve body 100.

[0038] Specifically, a second sealing ring 310 and a third sealing ring 320 are further provided on the connecting shaft 223. The second sealing ring 310 is arranged at the upper end of the connecting shaft 223, and the second sealing ring 310 abuts against the inner end surface of the through hole 214 of the upper cover 212 to form a sealed state. Then the third sealing ring 320 is arranged at the lower end of the connecting shaft 223, and the third sealing ring 320 abuts against the inner end surface of the through hole 214 of the lower shell 211 to form a sealed state, so that the inside of the explosion-proof box body 210 is in a closed state.

[0039] Further, the clutch component 242 includes a driving wheel 2421, a driven wheel 2422, and an idler wheel 2423. The driving wheel 2421 is arranged on the driving shaft of the motor 241, the driven wheel 2422 is sleeved on the connecting shaft 223, and then the idler wheel 2423 is arranged between the two, and the idler wheel 2423 is respectively engaged with the driving wheel 2421 and the driven wheel 2422. Moreover, a jacking unit 243 is arranged between the motor 241 and the driving wheel 2421. The jacking unit 243 includes an upper jacking plate 2431, a lower jacking plate 2432, and a return spring 2433. The return spring 2433 is sleeved on the outer ends of the upper jacking plate 2431 and the lower jacking plate 2432, and the upper and lower ends of the return spring 2433 respectively abut against the driving wheel 2421 and the motor 241. Moreover, relatively protruding convex teeth 2434 are arranged on both the upper jacking plate 2431 and the lower jacking plate 2432. The number of the convex teeth 2434 is set to two and is distributed in an array on the end surface of the upper jacking plate 2431 or the lower jacking plate 2432. Moreover, a V-shaped groove 2435 with a reverse setting is arranged between the two convex teeth on the lower end surface of the upper jacking plate 2431. When the lower jacking plate 2432 rotates, its convex teeth 2434 can accurately abut against the convex teeth 2434 of the upper jacking plate 2431 at the highest point, so that the two slide against each other and jack up, thereby jacking up the driving wheel 2421 to be close to and engaged with the idler wheel 2423. When the convex teeth 2434 of the lower jacking plate 2432 are at the lowest point of the V-shaped groove 2435 of the upper jacking plate 2431, the driving wheel 2421 is far away from the idler wheel 2423, and the two have no meshing and transmission relationship. Specifically, during operation, after the motor 241 is started, the lower jacking plate 2432 will rotate, so that the convex teeth 2434 of the lower jacking plate 2432 rotate to the convex teeth 2434 of the upper jacking plate 2431, and the upper jacking plate 2431 is jacked up, so that the driving wheel 2421 is close to and engaged with the idler wheel 2423, and the driving wheel 2421 drives the driven wheel 2422 to rotate together through the idler wheel 2423, thereby making the connecting shaft 223 rotate, and finally realizing the automatic screwing to open / close the valve body 100 and changing the operating state of the valve body 100. On the contrary, when the motor 241 stops, the convex teeth 2434 of the lower jacking plate 2432 will move away from the convex teeth 2434 of the upper jacking plate 2431, and the convex teeth 2434 of the lower jacking plate 2432 will move to the lowest point of the V-shaped groove 2435 of the upper jacking plate 2431, so that the driving wheel 2421 is far away from the idler wheel 2423, and the meshing state between the two is cancelled, so that when the user manually rotates the control component 220, it will not affect the motor 241 and does not affect the normal use of the motor 241, playing a disconnection protection role.

[0040] In this embodiment, a downwardly protruding fixing groove 216 is provided in the lower shell 211, and the fixing groove 216 is used to place one end of the power supply motor 241 therein for stabilization. A positioning column 217 protruding upward is also provided in the lower shell 211, so that the positioning column 217 is located directly below the idler wheel 2423, so that the idler wheel 2423 can be installed on the upper end of the positioning column 217.

[0041] In this embodiment, the handwheel fixing member 222 is a handwheel cover mounted on the valve body 100 or a handwheel clamp clamped on the valve body 100, and the inner end of the handwheel fixing member 222 is provided with a protruding block that is clamped on the valve body 100 for limiting and fixing.

[0042] In this embodiment, the anti-rotation component 230 is a clamp including a first clamping member 231, a second clamping member 232 and a locking member 233.
