[0002] With the development and trend of current industrial automation technology, instruments and meters are indispensable key tools in industrial production. They can measure, record, and analyze various physical quantities. The accuracy and stability of instruments play a crucial role in ensuring product quality, improving production efficiency, and reducing energy consumption. The measurement parameters of instruments mainly include: temperature, pressure, liquid level, flow rate, and analytical instruments. Some of the measuring instruments are installed in the open air and are extremely vulnerable to the influence of external physical factors, resulting in corrosion of the shell or the instrument being damaged by external forces and unable to be used. This will greatly reduce the measurement accuracy and service life of the instrument, not only increasing the workload of maintenance personnel but also further increasing the cost investment of the enterprise. Therefore, it is necessary to set up a protection device outside the instrument to protect it. When the existing instrument protection device (such as a multifunctional protection device for instruments disclosed in the application number 201810893881.2) is in use, the protection shell is generally fixed to the pipeline by means of a clamp. The clamp is only applicable to pipelines of specific sizes, and for pipelines of different diameters, other sizes of clamps need to be replaced, so the versatility is poor.

The two insertion blocks 230 are respectively fixed to the other ends of the corresponding movable half-rings 220, and are respectively used to be inserted into the corresponding slots 211. Through the connection between the insertion blocks 230 and the slots 211, the other ends of the movable half-rings 220 are clamped with the other ends of the fixed half-rings 210.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 5 , the fixing mechanism 200 further includes a sleeve 240. Both ends of the sleeve 240 are open, and the sleeve 240 is arranged between the two fixed half-rings 210. The two ends of the sleeve 240 are respectively communicated with and fixedly connected to the corresponding two slots 211, so as to facilitate arranging the connecting mechanism 300 in the sleeve 240.

[0032] As a preferred embodiment, please refer to Figure 3 and Figure 4 , a jack 231 is formed on the insertion block 230. When the insertion block 230 is inserted into the slot 211, the jack 231 is communicated with the sleeve 240, so as to facilitate the end of the connecting mechanism 300 to enter the jack 231 from the sleeve 240, realizing the clamping connection between the movable half-ring 220 and the fixed half-ring 210.

[0033] As a preferred embodiment, please refer to Figure 3 and Figure 5 , the connecting mechanism 300 includes two insertion rods 310 and two elastic members 320. The two insertion rods 310 are both slidably arranged in the sleeve 240. The two elastic members 320 are both arranged in the sleeve 240. One ends of the two elastic members 320 are fixedly connected to the sleeve 240, and the other ends of the two elastic members 320 are respectively fixedly connected to one ends of the corresponding insertion rods 310, so that the other ends of the insertion rods 310 respectively enter the corresponding slots 211.

[0035] As a preferred embodiment, please refer to Figure 1 and Figure 5 , two guiding grooves 241 extending along the length direction of the sleeve 240 are oppositely formed on the side wall of the sleeve 240. The connecting mechanism 300 further includes two lever rods 330. One ends of the two lever rods 330 are respectively fixedly connected to the corresponding insertion rods 310, and the other ends of the two lever rods 330 respectively extend out of the sleeve 240 along the corresponding guiding grooves 241. By pulling the two lever rods 330 to approach each other, the two insertion rods 310 can be made to approach each other until the other ends of the two insertion rods 310 both enter the sleeve 240. At this time, the two elastic members 320 are both in a compressed state and accumulate compressed elastic potential energy. When the two insertion blocks 230 are respectively inserted into the corresponding slots 211, the two insertion holes 231 are both communicated with the sleeve 240. Release the two lever rods 330, and the two elastic members 320 both release the compressed elastic potential energy, pushing the two insertion rods 310 to move away from each other until the other ends of the two insertion rods 310 are inserted into the corresponding insertion holes 231. Since the bolt connection method is adopted, when disassembling and assembling the movable half ring 220 and the fixed half ring 210, tools are needed to remove the bolts. In the case of forgetting to bring tools, the protective shell 100 cannot be disassembled and assembled, which is very inconvenient. By adopting the insertion connection method of the insertion rod 310 and the insertion hole 231 to connect the movable half ring 220 and the fixed half ring 210, the disassembly and assembly of the movable half ring 220 and the fixed half ring 210 are very convenient. In the case of forgetting to bring tools, the protective shell 100 can also be disassembled and assembled.

[0036] As a preferred embodiment, the elastic member 320 is a spring, which can accumulate compressed elastic potential energy when subjected to pressure and release the compressed elastic potential energy when the pressure disappears.

[0037] As a preferred embodiment, please refer to Figure 3 , the fixing mechanism 200 further includes a connecting rod 260, which is arranged between the two movable half rings 220. Two ends of the connecting rod 260 are respectively fixedly connected to the corresponding two movable half rings 220, and the two movable half rings 220 can be made into a whole through the connecting rod 260.

By rotating the screw rod forward or backward, the screw rod can be moved closer to or away from the pipeline. When the end of the screw rod is pressed against the pipeline, the fixing mechanism 200 can be fixedly connected to the pipeline to prevent the protective shell 100 from shaking, thereby improving safety and stability.

[0039] In order to better understand the present invention, the following Figure 1 - Figure 5 The working principle of the technical solution of the utility model is described in detail:

[0040] When in use, the protective shell 100 is covered on the instrument, and the two fixed half rings 210 and the two movable half rings 220 are clamped on the pipe. By pulling the two levers 330 closer to each other, the two insertion rods 310 can be brought closer to each other until the other ends of the two insertion rods 310 enter the sleeve 240. At this time, the two elastic members 320 are in a compressed state and accumulate compressed elastic potential energy. The two plug blocks 230 are respectively inserted into the corresponding slots 211. At this time, the sockets 231 on the plug blocks 230 are connected to the sleeve 240. The two levers 330 are released, and the two elastic members 320 release the compressed elastic potential energy. The potential energy is used to push the two insertion rods 310 away from each other until the other ends of the two insertion rods 310 are respectively inserted into the corresponding insertion holes 231, thereby realizing the clamping connection between the two movable semi-rings 220 and the two fixed semi-rings 210, and then the screw is rotated in the forward direction to move the screw along the radial direction of the movable semi-ring 220 until the end of the screw is pressed against the side wall of the pipe, so that the fixing mechanism 200 can be fixedly connected to the pipe, thereby fixing the protective shell 100 on the pipe, preventing the protective shell 100 from shaking, and improving safety and stability. This protective device is suitable for installation on pipes within a certain diameter range and has strong versatility.

[0041] The utility model provides an instrument protection device with the following beneficial effects:

[0042] (1)When the two insertion blocks 230 are respectively inserted into the corresponding slots 211, the jacks 231 on the insertion blocks 230 communicate with the sleeve 240. Release the two lever rods 330, and both of the two elastic members 320 release the compressed elastic potential energy, pushing the two insertion rods 310 away from each other until the other ends of the two insertion rods 310 are respectively inserted into the corresponding jacks 231, realizing the clamping connection between the two movable half-rings 220 and the two fixed half-rings 210;

[0043] (2)Since the bolt connection method is adopted, when disassembling and assembling the movable half-ring 220 and the fixed half-ring 210, tools are needed to remove the bolts. In the case of forgetting to bring tools, the protective shell 100 cannot be disassembled and assembled, which is very inconvenient. By adopting the plug-in connection method of the insertion rod 310 and the jack 231 to connect the movable half-ring 220 and the fixed half-ring 210, the disassembly and assembly of the movable half-ring 220 and the fixed half-ring 210 are very convenient. Even in the case of forgetting to bring tools, the protective shell 100 can also be disassembled and assembled;

[0044] (3)It can prevent the protective shell 100 from shaking, improving safety and stability. This protective device is applicable to the installation of pipelines within a certain diameter range and has strong versatility.
