Description

Technical Field

[0001] This utility model relates to the field of infrared spectral gas cell sealing technology, specifically to an infrared spectral gas cell sealing structure. Background Technology

[0002] When using an infrared spectroscopy gas cell, the window structure and sealing structure need to be firmly and evenly pressed onto the cell body, usually by screws or clips. The sealing structure is used to fill the tiny gaps between the cell body and the window structure. However, most existing sealing structures only use thin gaskets for sealing. Due to the small contact area, leakage is prone to occur under high pressure, which has certain shortcomings. To address this, we propose a sealing structure for an infrared spectroscopy gas cell. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: an infrared spectral gas cell sealing structure, including a window seat, a retaining ring, a support assembly, a first rubber ring, a second rubber ring, and a cell body. The retaining ring is fixedly disposed on the inner side of the window seat. The support assembly includes a thin metal tube inserted inside the window seat and a fixing piece fixedly disposed on the outer side of the thin metal tube. The first rubber ring is inserted through the right side of the support assembly and is inserted and connected to the retaining ring. The second rubber ring is inserted through the left side of the support assembly. The cell body is inserted through the left side of the second rubber ring.

[0005] Preferably, a sealing groove for inserting the pool body is provided on the left side of the window seat.

[0006] Preferably, the left corner of the retaining ring is provided with a first rounded corner.

[0007] Preferably, an adhesive layer is fixedly provided on both sides of the fixing piece, and the adhesive layer is formed by coating the surface of the fixing piece with an adhesive.

[0008] Preferably, a locking block is fixedly provided on both sides of the fixing plate, and a plurality of the locking blocks are distributed circumferentially.

[0009] Preferably, an annular groove is provided on the right side of the first rubber ring, and a second rounded corner is provided at the corner on the right side of the annular groove, and several slots are provided on the left side of the first rubber ring.

[0010] Preferably, the second rubber ring has the same structure as the first rubber ring, and the second rubber ring and the first rubber ring are symmetrically distributed on the support component.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The first rubber ring of this utility model can be inserted and connected to the retaining ring through the annular groove, thereby increasing the contact area between the sealing structure and the window seat. Similarly, the second rubber ring can be inserted and connected to the pool body through the annular groove, thereby increasing the contact area between the sealing structure and the pool body, greatly improving the sealing effect. At the same time, the cooperation of the metal thin tube and the fixing plate of the supporting component can support and bind the first rubber ring and the second rubber ring. In addition, the binding of the window seat can prevent the first rubber ring and the second rubber ring from affecting the sealing effect due to deformation, further improving the sealing performance and wide application range. Furthermore, the first rubber ring and the second rubber ring are both fixed to the supporting component by adhesive, thereby allowing the first rubber ring and the second rubber ring to be disassembled for replacement.

This embodiment provides an infrared spectral gas cell sealing structure, including a window seat 100, a retaining ring 200, a support component 300, a first rubber ring 400, a second rubber ring 500, and a cell body 600.

[0028] Specifically, a sealing groove 101 for inserting the pool body 600 is provided on the left side of the window seat 100. In use, the support assembly 300, the first rubber ring 400 and the second rubber ring 500 can be fixed in the window seat 100 through the sealing groove 101 for sealing.

[0029] Specifically, the retaining ring 200 is fixedly installed on the inner side of the window seat 100. The left corner of the retaining ring 200 is provided with a first rounded corner 201. In use, the retaining ring 200 can be inserted into the first rubber ring 400, thereby increasing the contact area to improve the sealing between the first rubber ring 400 and the window seat 100. The first rounded corner 201 allows the retaining ring 200 to be quickly inserted into the first rubber ring 400.

[0030] Specifically, the support component 300 includes a thin metal tube 301 inserted inside the window seat 100 and a fixing piece 302 fixedly disposed on the outside of the thin metal tube 301. An adhesive layer 303 is fixedly disposed on both sides of the fixing piece 302, and the adhesive layer 303 is formed by coating the surface of the fixing piece 302 with an adhesive. A locking block 304 is fixedly disposed on both sides of the fixing piece 302, and several locking blocks 304 are circumferentially distributed. In use, the cooperation between the thin metal tube 301 and the fixing piece 302 can support and bind the second rubber ring 500 and the first rubber ring 400. In addition, the binding of the window seat 100 can prevent the first rubber ring 400 and the second rubber ring 500 from being deformed and affecting the sealing effect, thereby improving the sealing performance. The adhesive layer 303 facilitates the fixing of the first rubber ring 400 and the second rubber ring 500 onto the fixing piece 302.

[0031] Specifically, the first rubber ring 400 is inserted into the right side of the support assembly 300 and is connected to the retaining ring 200. An annular groove 401 is provided on the right side of the first rubber ring 400, and a second rounded corner 402 is provided at the corner on the right side of the annular groove 401. Several retaining grooves 403 are provided on the left side of the first rubber ring 400. In use, the retaining ring 200 can be inserted into the first rubber ring 400 through the annular groove 401, thereby increasing the contact area for sealing. The second rounded corner 402 facilitates the insertion of the retaining ring 200 into the first rubber ring 400. Then, it can be engaged with the retaining block 304 through the retaining grooves 403 to fix the first rubber ring 400 and the second rubber ring 500 on the fixing plate 302.

[0032] Specifically, the second rubber ring 500 is inserted into the left side of the support assembly 300. The second rubber ring 500 has the same structure as the first rubber ring 400. The second rubber ring 500 and the first rubber ring 400 are symmetrically distributed on the support assembly 300. In use, the first rubber ring 400 and the second rubber ring 500 seal the window seat 100 and the pool body 600 respectively to prevent gas leakage.

[0033] Specifically, the pool body 600 is inserted into the left side of the second rubber ring 500. During use, the contact area is increased by inserting the pool body 600 into the annular groove 401 of the second rubber ring 500, thereby improving the sealing performance.

[0034] The working principle and usage process of this utility model are as follows: In use, the first rubber ring 400 can be inserted into the right side of the support component 300 and fixed by adhesive layer 303. During the bonding process, the slot 403 is aligned with the block 304 and engaged. Similarly, the second rubber ring 500 can be inserted into the left side of the support component 300 and fixed by adhesive layer 303. Then, the support component 300, the first rubber ring 400 and the second rubber ring 500 are aligned with the sealing groove 101 of the window seat 100 and inserted. After connection, the retaining ring 200 will automatically be inserted into the annular groove 401 of the first rubber ring 400. Then, the right side of the pool body 600 can be aligned with the annular groove 401 of the second rubber ring 500 and inserted. The support component 300, the first rubber ring 400 and the second rubber ring 500 can then seal the window seat 100 and the pool body 600.
