[0002] Multi-turn valves usually refer to valves that require multiple rotations to be fully opened or closed, and a gear box is a device used to increase the operating torque of the valve. The existing publication number is: CN112594439B, which discloses a multi-turn valve gear box that is easy to disassemble and assemble and its installation method. The device increases the height of the valve gear box body through the support of the legs, and does not require manual movement for installation, making the installation of the valve gear box more convenient, and is easy to operate through the installation structure between the first limit plate and the second limit plate.

The operation process is relatively cumbersome, and the first limit plate only falls on the mounting part and the mounting pillar by gravity. When combined with the second limit plate, it can only wrap the mounting part and the mounting pillar, and it is difficult to provide them with a stable clamping force, which may affect the stability of the connection between the mounting part and the mounting pillar.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The existing multi-turn valve gearbox needs to drive multiple parts to achieve disassembly and assembly during the actual disassembly and assembly, and the operation process is relatively cumbersome. In order to solve the defects of the multi-turn valve gearbox during the disassembly and assembly process, please refer to Figure 1-Figure 6The utility model provides a multi-turn valve gearbox that is easy to disassemble and assemble. Only one component, a driving hand wheel, is needed to complete the entire process of installing and limiting the equipment. The disassembly is similar, which saves operation steps and is easy to use. The equipment is based on a gearbox body 1 and a mounting pillar 2 provided on the gearbox body 1. The mounting pillar 2 is used to connect with the mounting end of an external mounting part. A fixing frame 5 is fixedly installed on one side of the gearbox body 1. A lower clamping plate 3 and an upper clamping plate 4 are respectively installed on the upper and lower sides of the fixing frame 5 through telescopic springs 10. There are multiple telescopic springs 10, and the multiple telescopic springs 10 are evenly distributed at equal intervals. The lower clamping plate 3 and the upper clamping plate 4 are both slidably connected to the outside of the gearbox body 1 to fit the mounting part to the mounting pillar 2. The lower clamping plate 3 and the upper clamping plate 4 can be combined by the elastic force of the telescopic spring 10 to clamp the mounting part and the mounting pillar 2. The fixing can enhance the stability of the connection between the mounting piece and the mounting pillar 2, and the left and right sides of the lower card plate 3 and the upper card plate 4 are fixedly connected with abutment plates 7. The two sets of abutment plates 7 can be opened to drive the lower card plate 3 and the upper card plate 4 to separate, so that the mounting pillar 2 and the mounting piece can be disassembled and assembled. Two disassembly and assembly mechanisms 6 are arranged on the outside of the gear box body 1. The lower card plate 3 and the upper card plate 4 can be opened and limited by the disassembly and assembly mechanisms 6. The two disassembly and assembly mechanisms 6 are respectively arranged on the left and right sides of the mounting pillar 2, wherein the interior of the bracket 61 is symmetrically rotatably installed with a rotating shaft 62, and the external fixed sleeve of the rotating shaft 62 is provided with a top plate 63, and the two top plates 63 are arranged in a Symmetrically arranged, the two top plates 63 rotate in opposite directions, and the abutting plates 7 on the lower card plate 3 and the upper card plate 4 can be stretched apart. At this time, the telescopic spring 10 is deformed to separate the lower card plate 3 and the upper card plate 4, so that the mounting piece can be fitted with the mounting pillar 2, and then the two top plates 63 are rotated together, and the lower card plate 3 and the upper card plate 4 can be combined by the elastic force of the telescopic spring 10 to clamp the mounting pillar 2 and the mounting piece to complete the preliminary installation. Both sides of the lower card plate 3 are provided with through grooves 31, and both sides of the upper card plate 4 are provided with avoidance grooves 41, and both sides of the bottom of the upper card plate 4 are fixedly connected to the limiting frame 42, and the limiting frame 42 is adapted to the through groove 31, and the limiting frame 42 and The avoidance grooves 41 are all compatible with the top plates 63. After the lower card plate 3 and the upper card plate 4 are combined, the limit frame 42 can be inserted into the through groove 31, and then the sliding bracket 61 drives one of the top plates 63 to enter the through groove 31 and the limit frame 42 in turn, and the other top plate 63 can enter the avoidance groove 41. The top plate 63 can limit the limit frame 42 to prevent the limit frame 42 from falling off from the through groove 31, thereby preventing the lower card plate 3 and the upper card plate 4 from separating. The top plate 63 can not only control the opening and closing of the lower card plate 3 and the upper card plate 4, but also limit the lower card plate 3 and the upper card plate 4 when the lower card plate 3 and the upper card plate 4 are combined. The operation steps are simple and easy to disassemble and assemble.

[0025] Since the two top plates 63 need to prop up the two abutment plates 7 on the lower card plate 3 and the upper card plate 4, the two top plates 63 need to rotate in opposite directions. In order to realize the reverse rotation of the two top plates 63, refer to Figure 4 As shown, the ends of the two rotating shafts 62 are fixedly sleeved with spur gears 64, the two spur gears 64 are meshed with each other, and one end of one of the rotating shafts 62 passes through the bracket 61 and is fixedly connected to a handwheel 65, and the handwheel 65 requires artificial external force to rotate. Turning the handwheel 65 can drive one of the rotating shafts 62 to rotate, and the rotating shaft 62 drives the other rotating shaft 62 to reverse through the two spur gears 64, thereby realizing the opening and closing of the two top plates 63. When the two top plates 63 are opened, the two abutment plates 7 on the lower card plate 3 and the upper card plate 4 can be propped up to separate the lower card plate 3 from the upper card plate 4.

[0026] In order to facilitate the control of the top plate 63 entering the avoidance groove 41 and the limit frame 42, a slider 66 is fixedly connected to one end of the bracket 61 facing away from the hand wheel 65, and a slide groove 9 is provided on the side of the gear box body 1 for the slider 66 to slide left and right. Pulling the hand wheel 65 can drive the slider 66 to slide along the slide groove 9, thereby controlling the top plate 63 to enter and exit the avoidance groove 41 and the limit frame 42.

[0027] Since the slider 66 may slide automatically in the slide groove 9, the top plate 63 will fall off from the limit frame 42, affecting the limiting effect of the top plate 63 on the lower card plate 3 and the upper card plate 4. In order to solve the technical problem, two clamps 8 are provided on the gear box body 1 for limiting the slider 66. The two clamps 8 are respectively arranged on both sides of the slide groove 9. Among them, a stopper 83 is slidably installed inside the fixing frame 81, and a connecting spring 82 is fixedly connected between the stopper 83 and the inner wall of the fixing frame 81. The outside of the slider 66 and the stopper 83 are both provided with chamfers. When the slider 66 slides, the stopper 83 can be squeezed to slide toward the inside of the fixing frame 81. At this time, the connecting spring 82 is deformed. When the slider 66 slides over the stopper 83, the stopper 83 can be slid out by the elastic force of the connecting spring 82 to limit the slider 66. It is necessary to manually pull the hand wheel 65 to drive the slider 66 to slide, which can prevent the top plate 63 from falling off the limit frame 42.
