[0028] 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.

[0029] Example 1

[0030] See also Figure 1-Figure 3 The utility model provides a technical solution: an auxiliary protection device based on instrument use, including a cover shell 1, an observation window 11 arranged on the cover shell 1, a threading tube 12 fixedly connected to both sides of the cover shell 1 and connected to the inside of the cover shell 1, a base 2 arranged on the side of the cover shell 1 away from the observation window 11, and a clamping mechanism 23 arranged on the base 2 close to the side of the cover shell 1.

[0031] The observation window 11 is hinged to the cover shell 1. A flat bolt 111 is screwed on one side of the cover shell 1 away from the hinge of the observation window 11. A lock hole 112 is opened at a position corresponding to the flat bolt 111 on the observation window 11. The end of the flat bolt 111 passes through the cover shell 1 and extends into the lock hole 112. Lock bolts 28 screwed to the base 2 are inserted at positions corresponding to the four corners of the cover shell 1.

[0032] The clamping mechanism 23 includes clamping rods 231 symmetrically arranged on a side of the base 2 close to the housing 1 and elastic ropes 24 fixedly installed at corresponding positions on both sides between the two clamping rods 231 .

[0033] When in use, place one side of the instrument against one of the clamping rods 231 and push it, then use the other hand to pull open the other clamping rod 231, so that the instrument can be smoothly placed between the two clamping rods 231. After releasing the hand, the two clamping rods 231 are reset and clamped on the base 2 under the action of the elastic rope 24, and then the cover 1 is covered on the base 2. At the same time, the external connecting wire is inserted into the cover 1 through the threading tube 12 and connected to the instrument, and then the locking bolt 28 is used to pass through the four corners of the cover 1 and tighten it on the base 2 to complete the locking. The dial of the instrument can be observed through the observation window 11. When maintenance and disassembly are required, the disassembly part can be selected as needed. For simple maintenance, the flat bolt 111 can be directly unscrewed to open the observation window 11, thereby exposing the wiring points on the front and side of the instrument. For more complicated maintenance or replacement of the instrument, the cover 1 and the base 2 can be separated by removing the locking bolt 28, thereby exposing the entire instrument, which is convenient for subsequent operations. The entire maintenance method is relatively rich and easy to operate, so it is more practical.

[0034] Specifically, a positioning block 21 is fixedly connected to one side of the base 2 close to the cover shell 1, and the clamping rod 231 is hinged to the positioning block 21; the positioning block 21 on the base 2 can help to locate the base 2 when the cover shell 1 is covered, and can be aligned faster so that the locking bolt 28 can be used for locking.

[0035] Furthermore, the positioning block 21 is provided with an elastic pad 22, and the clamping rod 231 is provided with a rubber sleeve; the elastic pad 22 and the rubber sleeve increase the friction on the bottom and sides of the meter, and the buffer provided by the elasticity can also play a protective role, making the meter more stable during use.

[0036] It should be noted that the end of the wire threading tube 12 away from the cover shell 1 has a sealing sleeve 121, the position of the cover shell 1 corresponding to the observation window 11 has a sealing strip, and the position of the base 2 corresponding to the positioning block 21 around the position also has a sealing strip. In addition, the side wall of the cover shell 1 has fins 13; by supplementing the sealing structure at the joint, the sealing of the cover shell 1 and the base 2 after installation is increased, which can effectively prevent the instrument body from being disturbed by dust. At the same time, the heat dissipation efficiency is improved by the fins 13, which can play a role in dust and explosion prevention and can extend the service life of the instrument.

[0037] Example 2

[0038] Different from the first embodiment, ear pieces 25 are fixedly connected to the sides of the base 2 at positions corresponding to the four corners.

[0039] Furthermore, the ear piece 25 is equipped with a U-shaped hoop 26 , both ends of the U-shaped hoop 26 pass through the two ear pieces 25 on the same side respectively, and both ends of the U-shaped hoop 26 are screwed with lock nuts 27 .

[0040] By means of the ear pieces 25 arranged at the four corners of the base 2, the whole can be fixed at the target position by bolts. At the same time, the matching U-shaped hoop 26 and lock nut 27 help to fix the whole on the pipe fitting. The specific operation is to place the base 2 on the pipe fitting, insert the U-shaped hoop 26 from the opposite side around the pipe fitting to the ear piece 25 on the same side, and then use the lock nut 27 to tighten the end of the U-shaped hoop 26 until the U-shaped hoop 26 clamps the pipe fitting, thereby keeping the whole fixed, increasing the fixing method of the device to improve the application range.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
