It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] Please see Figures 1-6 An auxiliary manual valve switching mechanism, provided in one embodiment of the present invention, includes:

[0036] Limit component A is used to open and close the auxiliary manual valve; and

[0037] Protective mechanism 6 is used to protect the limiting component A from falling.

[0038] The limiting assembly includes a cylinder A1, a cylinder B2, a limiting cylinder A3, and a limiting cylinder B4. The cylinder B2 is slidably engaged with the cylinder A1. The limiting cylinder A3 is fixedly connected to the cylinder A1. The limiting cylinder B4 is fixedly connected to the mounting seat A5, which is fixedly connected to the cylinder B2. The mounting seat A5 is slidably engaged with the cylinder A1. The cylinder B2 is fixedly connected to the cylinder A1 by a bolt assembly.

[0039] Specifically, the limiting cylinder A3 is fixedly connected to the cylinder body A1 by welding. Those skilled in the art should know that the purpose of this setting is to limit the connection of the limiting cylinder A3 to the cylinder body A1. Therefore, in some embodiments, the limiting cylinder A3 can also be connected to the cylinder body A1 by integral casting or by snap-fit ​​connection.

[0040] Specifically, the limiting cylinder B4 is fixedly connected to the mounting base A5 by welding, and the mounting base A50 is fixedly connected to the cylinder B2 by welding.

[0041] Specifically, the protective mechanism 6 includes a screw cylinder A601, a mounting base B602, and a rod body A603. The mounting base B602 is rotatably connected to the screw cylinder A601, and a torsion spring A (not shown in the figure) is provided between them. The rod body A603 is fixedly connected to a pin (not shown in the figure) rotatably connected to the mounting base B602. The pin is slidably engaged with a ratchet 608 embedded in the mounting base B602. The mechanism also includes:

[0042] Limiting component B604 is used for limiting the movement of the device; and

[0043] The actuator 605 is used to drive the screw barrel A601 to perform linear motion;

[0044] The limiting component B604 includes a mounting base C6041, a pressure plate 6042, a rod B6043, and an elastic element 6044. The mounting base C6041 is hinged to the rod A603, and a torsion spring B (not shown in the figure) is provided between them. The rod B6043, which is slidably engaged with the mounting base C6041, is fixedly connected to the pressure plate 6042. The elastic element 6044 is fixedly connected to the mounting base C6041 and the rod B6043.

[0045] The pushing assembly 605 includes a screw barrel B6051, a limiting rod 6052, a rotating drum 6053, and a drive box 606. The screw barrel B6051 is threadedly connected to the screw barrel A601. The screw barrel B6051 is rotatably connected to the drive box 606, which is fixedly connected to the cylinder A1. The rotating drum 6053 is rotatably connected to the drive box 606. The rotating drum 6053 is driven by the screw barrel B6051 through a transmission assembly 6054. The screw barrel A601 is slidably engaged with the limiting rod 6052, which is fixedly connected to the drive box 606. Technical personnel can drive the rotating drum 6053 to rotate by inserting the limiting cylinders A3 and B4 into both sides of the manual valve support rod. The rotating drum 6053 drives the screw drum B6051 to rotate through the transmission component 6054. The screw drum B6051 pushes the screw drum A601, which is threaded to it, to move linearly along the length of the limiting rod 6052. The screw drum A601 pushes the mounting seat B602 to move linearly. The mounting seat B602 pushes the rod body A603 to move linearly, thereby driving the mounting seat C6041. At this time, the two pressure plates 6042 are inserted into the outer edge of the manual valve and wrap around it, thereby achieving the technical effect of confining the entire device to the manual valve and preventing the entire device from falling off the manual valve. In particular, it can prevent the entire device from falling off the manual valve when the technical personnel turn the cylinder body A1 to make it form a lever with the limiting cylinders A3 and B4 to turn the manual valve.

[0046] Specifically, the elastic element 6044 is a spring. Those skilled in the art should know that the purpose of this arrangement is to provide elastic support for the rod B6043, that is, to provide tension to the pressure plate 6042. Therefore, in some embodiments, the elastic element 6044 can also be configured as a compression spring or an elastic steel plate.

[0047] Specifically, the rotating drum 6053 is provided with a handle 6055, which is slidably engaged with the rotating drum 6053. The purpose of this arrangement is to facilitate the rotation of the rotating drum 6053 relative to the drive box 606 by relevant technicians.

[0048] Specifically, a limiting slider 607 for limiting the position of the screw barrel A601 is fixedly connected to the cylinder A1, and the limiting slider 607 slides in cooperation with the cylinder A1. The purpose of this arrangement is to limit the position of the screw barrel A601.

[0049] Specifically, the transmission assembly 6054 includes a worm (not shown in the figure) and a worm wheel (not shown in the figure). The worm is sleeved on and fixedly connected to the rotating drum 6053, and the worm wheel is sleeved on and fixedly connected to the screw barrel B6051. The worm and the worm wheel mesh with each other. The rotating drum 6053 drives the worm to rotate, and the worm, through the meshing worm wheel, drives the screw barrel B6051 to rotate. The purpose of this arrangement is to convert the rotational motion of the rotating drum 6053 into the rotational motion of the screw barrel B6051.

[0050] As an alternative to the transmission assembly 6054, in some embodiments, the transmission assembly 6054 includes pulley A, pulley B, and a transmission rope. Pulley A is sleeved on and fixedly connected to the rotating drum 6053, and pulley B is sleeved on and fixedly connected to the screw barrel B6051. Pulley A is connected to pulley B via the transmission rope.

[0051] Specifically, the pressure plate 6042 is an arc-shaped plate. Those skilled in the art should know that the purpose of this setting is to increase the coverage of the pressure plate 6042 with the outer ring of the manual valve. Therefore, in some embodiments, the pressure plate 6042 can also be set as a C-shaped plate or a V-shaped plate.

[0052] Specifically, the edge of the pressure plate 6042 smoothly transitions to an arc-shaped surface. The purpose of this design is to facilitate the insertion of the outer ring of the manual valve between the two pressure plates 6042.

[0053] In this embodiment of the invention, a person skilled in the art can insert limiting cylinders A3 and B4 into both sides of the manual valve support rod, place cylinder A1 on the outer ring of the manual valve, and fix cylinder B2 to cylinder A1 using a bolt assembly. At this point, cylinder A1, limiting cylinder A3, and limiting cylinder B4 form a lever. The person skilled in the art can then insert the handle 6055 into the rotating cylinder 6053 and push the handle 6055 to rotate the rotating cylinder 6053. The rotating cylinder 6053, through the transmission assembly 6054, drives the screw cylinder B6051 to rotate. Cylinder B6051 pushes the threadedly connected screw cylinder A601 to move linearly along the length of the limiting rod 6052. Screw cylinder A601 pushes the mounting base B602 to move linearly. Mounting base B602 pushes the rod A603 to drive the mounting base C6041 to move linearly. At this time, the two pressure plates 6042 are engaged with the outer edge of the manual valve and wrap around it, limiting the entire device to the manual valve. At this time, relevant technicians can tighten and loosen the manual valve by applying force to the cylinder A1.

[0054] Please see Figure 2 as well as Figure 3 In one embodiment of the present invention, a pointer 7 is fixedly connected to the cylinder B2, and the pointer 7 is slidably engaged with the cylinder A1. The cylinder A1 has graduation lines. Those skilled in the art can remove the bolt assembly to allow the cylinder B2 to slide along the cylinder A1, thus allowing the pointer 7 to slide along the cylinder A1. At this time, those skilled in the art can use the limiting cylinders A3 and B4, along with the pointer 7, to measure the dimensions of objects positioned on the cylinder A1.

[0055] Please see Figure 2 , Figure 4 , Figure 5 as well as Figure 6 As an embodiment of the present invention, the device proposed in this invention can also be used as a bending tool. Its operating principle is as follows: A technician removes the limiting component B604 from the rod A603 and places the plate on the mounting base A5, making it abut against the limiting cylinder B4. The technician then rotates the rod A603 to adjust the opening size between the two rods A603 as needed. The rotating cylinder 6053 is then rotated via the handle 6055, causing the screw to rotate. The screw, through a meshing worm gear, pushes the screw cylinder B6051 to rotate. The screw cylinder B6051 pushes the threadedly connected screw cylinder A601 to move linearly along the length of the limiting rod 6052 until the two rods A603 press against the other side of the plate. At this point, the plate is subjected to force at three points. The technician then continuously pushes the handle 6055 to rotate the rotating cylinder 6053, causing the two rods A603 to move linearly until the plate is bent to the desired angle.

[0056] Specifically, the mounting base B602 is provided with a measuring scale for measuring the angle between the rod A603 and the mounting base B602. The purpose of this setting is to measure the opening size of the two mounting bases B602 and to ensure that the mounting bases B602 are in a symmetrical state when bent.

[0057] The aforementioned auxiliary switch manual valve mechanism includes a device body 8, a support rod 9, and an outer ring 10. The support rod is fixedly connected to the device body and the outer ring.
