Description

Technical Field

[0001] This utility model relates to the field of thermal control instrument installation technology, specifically a locking mechanism for thermal control instruments. Background Technology

[0002] Thermal control instruments are short for thermal energy control. The installation of thermal control instruments mainly includes the installation of various measuring devices such as pressure, temperature, analytical instruments, actuators, flow measurement elements, and level gauges. During the installation of some thermal control instruments, they need to be mounted on the wall for easy observation and data reading by staff. The existing installation methods mostly use bolts to fix them to the wall, which uses too many bolts, making disassembly and disassembly during operation and maintenance complicated, resulting in poor practicality. Moreover, repeated disassembly and installation can cause stripped threads, affecting reuse.

[0003] According to the publication number CN221145866U, a locking mechanism for a thermal control instrument is disclosed. The thermal control instrument body is installed on the base by sliding through a slider and a groove. After sliding to the required extent, the insert block can be inserted into the slot to complete the initial positioning installation similar to a tenon and mortise. Then, the buckle is bent to cooperate with the limiting block to perform a secondary locking and reinforcement of the installation of the thermal control instrument body.

[0004] In the process of realizing this utility model, the inventors discovered that at least the following problems in the prior art have not been solved. In the above case, the thermal control instrument body is installed by using a special shaped buckle in conjunction with a limiting block. However, the buckle will wear out after long-term use, causing the buckle to loosen and affecting the stability of the thermal control instrument.

[0005] Therefore, we propose a locking mechanism for thermal control instruments that can solve the above problems. Utility Model Content

[0008] As an optional solution to the technical solution of this application, the two sets of positioning grooves are respectively connected to two sets of card slots, and the slot is connected to the card slot.

[0009] As an optional solution to the technical solution of this application, the card slot is arc-shaped, and the card block matches the size of the slot and the card groove.

[0010] As an optional solution to the technical solution of this application, the dimensions of the positioning pin and the positioning groove are matched, and the dimensions of the thermal control instrument body and the mounting groove are matched.

[0011] As an optional solution to the technical solution of this application, a fixing groove is provided in the middle of the inner wall of the mounting groove, and the rear end of the spring is fixedly installed inside the fixing groove.

[0012] As an optional solution to the technical solution of this application, a fixing plate is fixedly installed at the rear end of the card holder, and four sets of fixing holes are evenly opened on the front side of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by combining the card slot, slot and card block, it is convenient to engage the card seat with the thermal control instrument body.

[0018] Please see Figures 1-2This utility model provides a technical solution: a locking mechanism for a thermal control instrument, including a locking seat 1 and a thermal control instrument body 12. A mounting groove 11 is provided in the middle of the front side of the locking seat 1, and the rear end of the thermal control instrument body 12 is movably connected to the mounting groove 11. The locking structure is used for locking the locking seat 1 and the thermal control instrument body 12. The locking structure includes two sets of locking blocks 15 and springs 17. The two sets of locking blocks 15 are symmetrically installed on both sides of the mounting end of the thermal control instrument body 12. The inner wall of the mounting groove 11 is symmetrically provided with locking slots 13. The locking slots 13 are arc-shaped. The upper and lower ends of the front side of the locking seat 1 are symmetrically provided with slots 14. The slots 14 are connected to the locking slots 13. The locking blocks 15 are movably connected to the slots 14 and the locking slots 13.

[0019] In this technical solution, the locking blocks 15 at both ends of the thermal control instrument body 12 are inserted into the slots 14 opened on the front side of the card holder 1. The slots 14 are connected to the card slots 13. The thermal control instrument body 12 is rotated counterclockwise so that the locking blocks 15 are screwed into the card slots 13, which facilitates the engagement between the card holder 1 and the thermal control instrument body 12.

[0020] In this embodiment, the front end of the spring 17 is movably connected to the rear end of the thermal control instrument body 12. The two ends of the front side of the card seat 1 are symmetrically provided with positioning grooves 19. The two sets of positioning grooves 19 are respectively connected to the two sets of card slots 13. The front end of the card block 15 is fixedly installed with a positioning pin 18. The positioning pin 18 is movably connected with the positioning groove 19. The size of the positioning pin 18 and the positioning groove 19 are matched. The rear end of the card seat 1 is fixedly installed with a fixing plate 2. The front side of the fixing plate 2 is evenly provided with four sets of fixing holes 21.

[0021] In this technical solution, a spring 17 is provided on the inner side of the mounting groove 11. The elastic force of the spring 17 can push the locking blocks 15 at both ends of the thermal control instrument body 12 to move forward, so that the positioning pin 18 is inserted into the positioning groove 19 opened on the front side of the card seat 1, further limiting and fixing the thermal control instrument body 12, improving the connection stability between the thermal control instrument body 12 and the card seat 1. The card seat 1 can be fixed in the designated position by bolts passing through the fixing holes 21 opened in the fixing plate 2.

[0022] In this embodiment, a fixing groove 16 is provided in the middle of the inner wall of the mounting groove 11, and the rear end of the spring 17 is fixedly installed inside the fixing groove 16. The thermal control instrument body 12 is matched with the size of the mounting groove 11, and the size of the locking block 15 is matched with the size of the slot 14 and the slot 13.

[0023] In this technical solution, the compressed spring 17 can be housed by the fixing groove 16, and the connection stability between the thermal control instrument body 12 and the mounting groove 11 can be improved by matching the dimensions of the thermal control instrument body 12 and the mounting groove 11.

[0024] When using a locking mechanism for a thermal control instrument, the locking blocks 15 at both ends of the thermal control instrument body 12 are inserted into the slots 14 opened on the front side of the card holder 1. At this time, the spring 17 is compressed in the fixing groove 16 and communicates with the card slot 13 through the slot 14. The thermal control instrument body 12 is rotated counterclockwise so that the locking blocks 15 are screwed into the card slot 13, which facilitates the locking of the card holder 1 and the thermal control instrument body 12. At this time, the positioning pin 18 is aligned with the positioning groove 19. Then, the thermal control instrument body 12 is released. Due to the elastic force of the spring 17, the locking blocks 15 at both ends of the thermal control instrument body 12 can be pushed forward so that the positioning pin 18 is inserted into the positioning groove 19 opened on the front side of the card holder 1, which further limits and fixes the thermal control instrument body 12, improving the connection stability between the thermal control instrument body 12 and the card holder 1.
