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.

[0021] See also Figure 1-Figure 5 A protective device for an operating valve group includes a valve body group 1, an outer shell 2 is provided at the front end of the valve body group 1, a plurality of round holes 4 are opened on the outer edge of the outer shell 2, an F-shaped blocking rod 5 is movably sleeved on the inner wall of the round hole 4, a connecting rod 6 is fixedly sleeved on the outer edge of the F-shaped blocking rod 5, a connecting column 7 is movably sleeved on the inner wall of the top of the connecting rod 6, a connecting plate 8 is fixedly installed at one end of the connecting column 7 away from the connecting rod 6, a long rod 9 is fixedly installed on the outer edge of the connecting plate 8, when the F-shaped blocking rod 5 is in a horizontal state, the two blocking rods at the head of the F-shaped blocking rod 5 are aligned with each other. The operating rod on the valve body group 1 is blocked, so that the operating rod on the valve body group 1 cannot move, so that the valve body group 1 is protected, and by moving the long rod 9 to one side, the long rod 9 can drive the connecting plate 8 to rotate, and gradually the inclination direction of the connecting rod 6 changes, so that the connecting rod 6 changes from the left side to the right side. At the same time, the F-shaped blocking rod 5 changes from a horizontal state to a vertical state, so that the F-shaped blocking rod 5 does not limit the operating rod on the valve body group 1. At this time, the valve body group 1 can be operated, thereby improving the safety of the valve body group 1.

[0022] In a preferred embodiment, an arc groove 3 is provided on the outer wall of the outer shell 2, and the long rod 9 passes through the arc groove 3. Long grooves 21 are provided on the top and back of the outer shell 2. By utilizing the setting of the arc groove 3, the movement trajectory of the long rod 9 is arc-shaped, and the movement trajectory of the long rod 9 is the same as the shape of the arc groove 3, so that the long rod 9 can move reasonably, thereby improving the rationality of the device. By utilizing the setting of the long groove 21, when the operating rod on the valve body group 1 is moving, the operating rod will enter the long groove 21, so that the operating rod will not contact the outer shell 2, thereby improving the rationality of the device.

[0023] In a preferred embodiment, a left fixing plate 10 is fixedly assembled on the bottom of the outer shell 2, and a right fixing plate 11 is movably sleeved on the inner wall of the left fixing plate 10. The right fixing plate 11 can be extended and retracted in the left fixing plate 10, so that the distance between the right fixing plate 11 and the left fixing plate 10 can be changed, which is convenient for installing the device on the valve body group 1.

[0024] In a preferred embodiment, the outer edge of the left fixed plate 10 is fixedly equipped with a mounting bracket 12, the inner wall of the mounting bracket 12 is movably sleeved with a limiting ring 13, and the outer edge of the limiting ring 13 is fixedly equipped with a hexagonal screw 14, which is movably connected to the mounting bracket 12 through the limiting ring 13, so that the limiting ring 13 limits the hexagonal screw 14 on the mounting bracket 12, so that the hexagonal screw 14 will not detach from the mounting bracket 12, and the hexagonal screw 14 can only rotate on the mounting bracket 12, thereby improving the stability of the device.

[0025] In a preferred embodiment, the inner wall of the hexagonal screw 14 is threadedly connected with a long screw 15, and the end of the long screw 15 away from the hexagonal screw 14 is fixedly assembled on the right fixing plate 11. When the hexagonal screw 14 is rotated clockwise, the long screw 15 drives the right fixing plate 11 to move to the left, and at this time the left fixing plate 10 and the right fixing plate 11 are gradually clamped on the valve body group 1. When the hexagonal screw 14 is rotated counterclockwise, the long screw 15 drives the right fixing plate 11 to move to the right, and at this time the left fixing plate 10 and the right fixing plate 11 are gradually separated from the valve body group 1, thereby improving the installation speed and disassembly speed.

[0026] In a preferred embodiment, a support rod 17 is fixedly installed on the outer edge of the right fixed plate 11, and a slide rail 16 is slidably connected to the outer edge of the top of the support rod 17. The top of the slide rail 16 is fixedly installed on the bottom of the outer shell 2. The support rod 17 is arranged so that the support rod 17 can support the outer shell 2. During installation, the right fixed plate 11 needs to be displaced, and the support rod 17 moves on the slide rail 16.

[0027] Working principle: when in use, the F-shaped blocking rod 5 is in a vertical state, and the gap between the left fixing plate 10 and the right fixing plate 11 is larger than the valve body group 1. Then, the left fixing plate 10 and the right fixing plate 11 are placed on the valve body group 1. By rotating the hexagonal screw 14 clockwise, the long screw 15 drives the right fixing plate 11 to move to the left. At this time, the left fixing plate 10 and the right fixing plate 11 are clamped on the valve body group 1. Then, when it is necessary to install and protect the operating rod on the valve body group 1, the long rod 9 on the right is pushed to the left. At this time, the connecting plate 8 and the connecting column 7 follow the movement, and the connecting rod 6 The bottom position does not change, the top movement trajectory of the connecting rod 6 is an arc, the connecting rod 6 rotates from the rightmost side to the leftmost side, and the F-shaped baffle rod 5 changes from a vertical state to a horizontal state. At this time, the F-shaped baffle rod 5 protects the operating rod on the valve body group 1, and by pushing the long rod 9 to the right, the connecting plate 8 and the connecting column 7 follow the movement. The bottom position of the connecting rod 6 does not change, and the top movement trajectory of the connecting rod 6 is an arc. The connecting rod 6 rotates from the leftmost side to the rightmost side, and the F-shaped baffle rod 5 changes from a horizontal state to a vertical state. At this time, the F-shaped baffle rod 5 does not provide safety protection for the operating rod on the valve body group 1.
