Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automatic instruments, in particular to a protection structure for a chemical industry automatic instrument. BACKGROUND

[0002] Chemical industry instruments and automation technology emerged in the early 1940s, but at that time the instruments were bulky and had limited precision. With the rapid progress of semiconductor and integrated circuit technology, in the second half of the 1960s, chemical industry automatic instruments began to develop towards miniaturization and high performance, and computer data processing automation was realized. This change greatly promoted the automation process of the chemical industry.

[0003] However, in the chemical production environment, instruments often face the risk of external collision, which may cause damage or affect the measurement accuracy. For this reason, the Chinese utility model patent CN220554180U proposes a protection structure for a chemical industry automatic instrument, which aims to protect the instrument from external collision through a locking mechanism and a buffer mechanism. The protection structure directly fixes the fixed cover on the instrument body through the locking mechanism, realizing quick installation and disassembly. At the same time, the buffer mechanism can absorb the impact force of collision, further improving the protection effect. However, during the installation process, when the protection structure is installed on the instrument body, the instrument body needs to be first disassembled from the pipeline, then the base is installed, then the instrument body is reset, and finally the fixed cover is installed and connected with the locking mechanism on the base. This installation method not only consumes time and effort, but also may cause inconvenience to chemical production in actual operation, especially in the case where the instrument needs to be protected but the production process cannot be interrupted.

[0004] Therefore, the application provides a protection structure for a chemical industry automatic instrument to solve the above problems. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0023] Embodiment 1

[0024] The present embodiment provides a protection structure based on a chemical automation instrument, as shown in the figure, the protection structure comprises a shield 1 and a base assembly 2 arranged at the lower end of the shield 1 for sleeving on the pipeline of the chemical automation instrument. Figures 1-5

[0025] ​The base assembly 2 comprises a first hinged seat 21 and a second hinged seat 22 hinged with the first hinged seat 21, and a clamping groove 23 adapted to the pipeline of the instrument is arranged at the end of the first hinged seat 21 and the second hinged seat 22 close to each other. The top end of the first hinged seat 21 and the second hinged seat 22 is fixedly connected with a semicircular ring 24 for inserting into the protective cover 1. The base assembly 2 is hinged, so that the user can easily install the protective structure on the pipeline of the instrument without disassembling the instrument body, which greatly improves the installation efficiency. The semicircular ring 24 is inserted and matched with the protective cover 1, which ensures the stable installation of the base assembly 2 on the pipeline of the instrument and effectively prevents loosening or falling caused by external factors. During installation, the user first needs to pull the protective cover 1 off the fixed ring composed of two semicircular rings 24, so that the base assembly 2 is in an open state. Then, the movable end of the first hinged seat 21 and the second hinged seat 22 is opened around the hinged end, the clamping groove 23 is aligned with the pipeline of the instrument and clamped. Then, the movable end of the first hinged seat 21 and the second hinged seat 22 is closed in reverse, forming a stable clamping structure. Finally, the protective cover 1 is reassembled on the fixed ring composed of two semicircular rings 24, and the movable end of the base assembly 2 is locked by the insertion structure, and the whole installation process is completed. During use, the protective cover 1 can effectively isolate the instrument from external environmental factors, and the base assembly 2 ensures the stable installation and long-term use reliability of the protective structure. When the protective structure needs to be disassembled, the user only needs to repeat the reverse process of the above installation steps to easily complete the disassembly.

[0026] In order to improve the stability of the connection between the first hinged seat 21 and the second hinged seat 22, the end of the first hinged seat 21 close to the second hinged seat 22 is fixedly connected with a first reinforcing plate 211, and the end of the second hinged seat 22 close to the first hinged seat 21 is provided with a first insertion slot 221 for inserting the first reinforcing plate 211. The outer wall of the first reinforcing plate 211 abuts against the inner wall of the first insertion slot 221. Through the insertion and matching of the first reinforcing plate 211 and the first insertion slot 221, the stability of the splicing of the first hinged seat 21 and the second hinged seat 22 can be improved, and the phenomenon of shaking and misplacement of the movable end of the first hinged seat 21 and the second hinged seat 22 can be prevented.

[0027] In order to improve the stability of the connection between the protective cover 1 and the semicircular ring 24, the side of the two semicircular rings 24 away from each other is provided with a helical outer thread 241, and the inner wall of the protective cover 1 is provided with an inner thread 11 matched with the outer thread 241. The protective cover 1 is screwed onto the two semicircular rings 24. By screwing the protective cover 1 onto the two semicircular rings 24, the stability of the connection between the protective cover 1 and the semicircular ring 24 can be improved, and the fixed connection of the protective cover 1 and the two semicircular rings 24 is also facilitated.

[0028] Embodiment 2

[0029] Different from the embodiment 1, in order to align the connection of the external threads 241 on the two half-rings 24: the end of one of the half-rings 24 is fixedly connected with a second reinforcing plate 242, and the end of the other half-ring 24 is provided with a second insertion slot 243 for inserting the second reinforcing plate 242. The outer wall of the second reinforcing plate 242 abuts against the inner wall of the second insertion slot 243, and through the insertion fit between the outer wall of the second reinforcing plate 242 and the second insertion slot 243, the stability of the splicing of the two half-rings 24 can be improved, and the phenomenon of shaking and mispositioning at the splicing of the two half-rings 24 can be prevented, thereby facilitating the connection of the protective cover 1 and the half-rings 24.

[0030] In order to facilitate the base assembly 2 to be adapted to instrument pipes of different diameters: the first and second hinged seats 21 and 22 are each provided with a locking mechanism 3, which includes an arc-shaped clamping plate 31 movably embedded in a clamping groove 23, a threaded sleeve 32 rotatably inserted into the first or second hinged seat 21 or 22, a threaded rod 33 threadedly inserted into the threaded sleeve 32 and fixedly connected with the arc-shaped clamping plate 31, and a knob 34 fixedly connected to one end of the threaded sleeve 32 away from the threaded rod 33. Through the cooperation of the threaded sleeve 32 and the threaded rod 33, the arc-shaped clamping plate 31 can be driven to move closer to or away from the instrument pipe, thereby enabling the base assembly 2 to be fixedly installed on instrument pipes of different sizes. During installation, the user first needs to unscrew the protective cover 1 from the two half-rings 24, so that the base assembly 2 is in an open state. Then, the movable ends of the first and second hinged seats 21 and 22 are opened around their hinged ends, the clamping groove 23 is aligned with the pipe of the instrument and clamped tightly. Next, the movable ends of the first and second hinged seats 21 and 22 are closed in reverse to form a stable clamping structure. At this time, the arc-shaped clamping plate 31 may not have completely fitted the instrument pipe, so it is necessary to adjust the position of the arc-shaped clamping plate 31 by rotating the knob 34. When the threaded sleeve 32 is rotated clockwise, the arc-shaped clamping plate 31 moves away from the instrument pipe; when the threaded sleeve 32 is rotated counterclockwise, the arc-shaped clamping plate 31 moves closer to the instrument pipe. Until the arc-shaped clamping plate 31 is tightly fitted with the instrument pipe. Finally, the protective cover 1 is screwed back onto the two half-rings 24, the movable ends of the base assembly 2 are locked by the insertion structure, and the entire installation process is completed. During use, the protective cover 1 can effectively isolate the instrument from external environmental factors, while the base assembly 2 and the locking mechanism 3 ensure the stable installation and long-term use reliability of the protective structure. When the protective structure needs to be disassembled, the user only needs to repeat the reverse process of the above installation steps to easily complete the disassembly.

[0031] The locking mechanism 3 further comprises a guide groove 35 symmetrically formed in the clamping groove 23 and a guide plate 36 slidingly arranged in the guide groove 35 and fixedly connected with the arc-shaped clamping plate 31. Through the sliding cooperation between the guide plate 36 and the guide groove 35, not only can the circumferential rotation of the arc-shaped clamping plate 31 during movement be prevented, so as to ensure that the arc-shaped clamping plate 31 keeps a horizontal state during movement, but also a guiding effect on the arc-shaped clamping plate 31 during movement can be achieved.

[0032] It should be noted that the various standard parts used in the present application can be obtained from the market, and the non-standard parts can be specially customized. The connection methods such as threaded connection and hinging adopted in the present application are also very common means in the mechanical field, and the inventor will not repeat them here.

[0033] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solutions and concepts of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
