Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a pressure monitor for flange, which solves the problem that the existing pressure monitor is generally exposed to the outside, is very easy to be damaged by foreign objects or accidental contact by people, thereby causing property loss and having poor practicality.

[0005] To achieve the above object, the utility model provides the following technical solution: a flange pressure monitor, comprising a main body, a fixing box fixedly connected to the main body, a first protective cover hinged to the fixing box, a second protective cover hinged to the fixing box, and a rotating rod fixedly connected to both the first protective cover and the second protective cover;

[0006] The rotating rod is fixedly connected with a worm wheel, the worm wheel is meshed with a worm, the two worms are fixedly connected with a connecting rod, the connecting rod is fixedly connected with a driven bevel gear, the driven bevel gear is meshed with a driving bevel gear, and a pressure monitor body is arranged on the main body.

[0007] As a further solution of the utility model: two flanges are arranged on the main body, and a protective shell is fixedly connected to the first protective cover.

[0008] As a further solution of the utility model: a motor is fixedly connected to the inside of the protective shell, and a fan blade is fixedly connected to the output end of the motor.

[0009] As a further solution of the utility model: a plurality of heat dissipation holes are provided on the second protective cover, and a handle is fixedly connected to the pressure monitor body.

[0010] As a further solution of the utility model: a plastic sleeve is fixedly connected to the handle, and a rotating shaft is fixedly connected to the active bevel gear.

[0011] As a further solution of the utility model: one end of the rotating shaft is fixedly connected with a turning handle, and the rotating rod is rotatably connected to the fixing box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The flange pressure monitor is provided with a worm wheel, a worm, a driven bevel gear, an active bevel gear, a first protective cover and a second protective cover. When the pressure monitor body needs to be protected, the handle is turned to drive the rotating shaft, the active bevel gear, the driven bevel gear, the connecting rod and the worm to rotate. Since the spiral directions on the two worms are opposite, when the two worms rotate, the two worm wheels and the rotating rod will rotate in opposite directions, so that the first protective cover and the second protective cover are close to each other to cover the pressure monitor body, so that the pressure monitor body can be protected. When the pressure monitor body needs to be maintained, the handle is rotated in the opposite direction to make the first protective cover and the second protective cover move away from each other, so that the pressure monitor body can be maintained. The pressure monitor protects the pressure monitor body through the first protective cover and the second protective cover to prevent the pressure monitor body from being damaged after being hit, thereby avoiding property loss, and the first protective cover and the second protective cover can be quickly rotated and opened, so that the pressure monitor body can be conveniently maintained while protecting, thereby improving work efficiency.

[0014] 2. The flange pressure monitor is provided with a motor, a fan blade, a heat dissipation hole and a pressure monitor body. When the pressure monitor body is working, the motor is started to drive the fan blade to rotate. The fan blade will blow the heat emitted by the pressure monitor body when working and dissipate it from the heat dissipation hole, thereby quickly dissipating the heat of the pressure monitor body, preventing the pressure monitor body from being damaged due to excessive heat when working, and improving the service life of the pressure monitor body.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a pressure monitor for a flange, comprising a main body 1, a fixing box 3 is fixedly connected to the main body 1, a first protective cover 4 is hinged on the fixing box 3, a second protective cover 20 is hinged on the fixing box 3, a plurality of heat dissipation holes 8 are opened on the second protective cover 20, and a handle 10 is fixedly connected to the pressure monitor body 9. Because the handle 10 is provided, the handle 10 provides a gripping point, which is convenient for personnel to take the pressure monitor body 9, thereby improving the convenience of operation.

[0022] The first protective cover 4 and the second protective cover 20 are both fixedly connected with a rotating rod 12, the rotating rod 12 is fixedly connected with a worm wheel 19, and the worm wheel 19 is meshed with a worm 13. The handle 10 is fixedly connected with a plastic sleeve 11. Because the plastic sleeve 11 has an anti-slip effect, it is convenient for people to hold the handle 10, thereby improving the stability of the operation. The active bevel gear 16 is fixedly connected with a rotating shaft 15.

[0023] The two worm gears 13 are fixedly connected with a connecting rod 18, and a driven bevel gear 17 is fixedly connected to the connecting rod 18. The driven bevel gear 17 is meshed with a driving bevel gear 16. One end of the rotating shaft 15 is fixedly connected with a turning handle 14. Since the turning handle 14 is provided, a person turns the turning handle 14 to drive the rotating shaft 15 to rotate. The turning handle 14 makes the rotating shaft 15 easier to rotate, reducing the difficulty of operation. The rotating rod 12 is rotatably connected to the fixed box 3.

[0024] A pressure monitor body 9 is arranged on the main body 1, and two flanges 2 are arranged on the main body 1. A protective shell 5 is fixedly connected to the first protective cover 4. Because of the provision of the protective shell 5, the protective shell 5 can protect the motor 6 to prevent foreign objects from hitting the motor 6 and causing damage to the motor 6, and has a good protective effect. The motor 6 is fixedly connected inside the protective shell 5, and the output end of the motor 6 is fixedly connected to the fan blade 7.

[0025] The working principle of the utility model is:

[0026] When the pressure monitor body 9 needs to be protected, the turning handle 14 is turned to drive the rotating shaft 15, the active bevel gear 16, the driven bevel gear 17, the connecting rod 18 and the worm 13 to rotate. Since the spiral directions of the two worm gears 13 are opposite, when the two worm gears 13 rotate, the two worm wheels 19 and the rotating rod 12 will rotate in opposite directions, so that the first protective cover 4 and the second protective cover 20 are close to each other to cover the pressure monitor body 9, so that the pressure monitor body 9 can be protected. When the pressure monitor body 9 needs to be maintained, the turning handle 14 is turned in the opposite direction to make the first protective cover 4 and the second protective cover 20 move away from each other, so that the pressure monitor body 9 can be maintained. When the pressure monitor body 9 is working, the starting motor 6 drives the fan blades 7 to rotate, and the fan blades 7 will blow the heat emitted by the pressure monitor body 9 when it is working, and dissipate it from the heat dissipation holes 8, thereby dissipating the heat of the pressure monitor body 9.
