Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of MPCVD equipment accessories, and specifically relates to an observation window for MPCVD equipment and MPCVD equipment. Background Technology
[0002] Existing MPCVD equipment typically uses an observation window that is mounted on a threaded tube, which is then screwed to the MPCVD equipment, thus indirectly mounting the observation window onto the equipment. While this technology allows for flexible fixing of the observation window to the threaded tube and ensures a tight seal at the connection, as well as flexible fixing of the threaded rod to the MPCVD equipment and a tight seal at the connection, the threaded mounting structure can easily cause damage to the sealing ring during installation. This not only affects the sealing performance of the connection but also potentially shortens the lifespan of the sealing ring.
[0003] For example, the utility model with announcement number CN 217230928 U discloses an observation window for an MPCVD equipment and an MPCVD equipment. In the technical solution of this patent, a sealing element bracket is provided at the end face of the screw-in end of the external threaded tube, and a second annular seal is sleeved on the sealing element bracket. The sealing element bracket is a positioning sleeve. During the installation process, the sealing element bracket needs to be screwed and fixed to the equipment. During this process, the second annular seal is easily damaged by rotation and clamping, which will affect the service life of the second annular seal and the sealing effect. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an observation window for an MPCVD device and an MPCVD device. It not only satisfies the flexible fixing of the observation window and the connecting structure, as well as the flexible fixing of the connecting structure and the MPCVD device, but also ensures that the connection between the observation window and the connecting structure, and the connection between the connecting structure and the MPCVD device, have significant sealing performance. Furthermore, it effectively avoids rotational damage to the sealing structure at the connection between the observation window and the connecting structure, and the sealing structure at the connection between the connecting structure and the MPCVD device.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an observation window for an MPCVD device, including a connecting pipe, an annular placement groove with openings at both the top and bottom of the connecting pipe, an observation window being snapped into the annular placement groove, a first sealing ring being snapped into the bottom of the annular placement groove, a first mounting groove adapted to the first sealing ring being provided at the bottom of the annular placement groove, a pressure ring being vertically slidably disposed in the middle of the annular placement groove, a second sealing ring being snapped into the bottom of the pressure ring, a second mounting groove adapted to the upper middle part of the second sealing ring being provided at the bottom of the pressure ring, an annular pressure cap being screwed onto the inner side wall of the upper end of the annular placement groove, an annular pressure platform adapted to the pressure ring being provided at the bottom of the annular pressure cap, and a connecting module for connecting to the MPCVD device being provided at the bottom of the connecting pipe.
[0006] As a further improvement of this utility model, the top of the annular pressure cap is provided with multiple screw grooves.
[0007] As a further improvement of this utility model, the inner wall of the lower middle part of the annular placement groove is provided with a plurality of guide slides adapted to the observation window, and the side end of the pressure ring is provided with a plurality of guide grooves adapted to the corresponding guide slides.
[0008] As a further improvement of this utility model, the connecting module includes a connecting sleeve disposed at the bottom of the connecting tube, a third sealing ring being fitted on the upper outer side wall of the connecting sleeve, an extension ring plate being disposed at the bottom side of the connecting sleeve, a plurality of connecting bolts for screwing and fixing the MPCVD equipment being disposed on the extension ring plate, a connecting insertion hole adapted to the connecting sleeve being disposed on the MPCVD equipment, and a threaded connecting hole adapted to the connecting bolts being disposed on the MPCVD equipment.
[0009] As a further improvement of this utility model, the side end of the annular pressure cap is also provided with anti-slip texture.
[0010] As a further improvement of this utility model, an auxiliary groove is also provided on the inner sidewall of the middle part of the compression ring.
[0011] An MPCVD apparatus includes a viewing window for an MPCVD apparatus as described above.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] Firstly, the user can first engage and fix the first sealing ring with the first mounting groove, then engage and place the observation window into the annular placement groove, ensuring that the bottom of the observation window abuts against the top of the first sealing ring. Subsequently, the second sealing ring can be engaged and fixed with the second mounting groove. Next, through the sliding engagement of the guide slide plate and the guide groove, the compression ring is placed into the annular placement groove, and the second sealing ring is pressed between the compression ring and the top of the observation window. Then, the annular cover can be screwed and fixed to the upper end of the annular placement groove. During this process, the annular pressure plate applies a downward force to the compression ring, the second sealing ring, the observation window, and the first sealing ring, thereby screwing the annular cover together with the inner wall of the upper end of the annular placement groove. Through the cooperation of the first and second sealing rings, the connection between the observation window and the annular placement groove has significant sealing performance.
[0014] Secondly, the user can insert and fix the connecting sleeve into the connecting hole, and make the third sealing ring abut against the top outer wall of the MPCVD equipment. Then, multiple connecting bolts can pass through the extension ring plate and be screwed into the corresponding threaded connecting holes, thereby flexibly fixing the connecting sleeve and the MPCVD equipment together, and the third sealing ring can make the connection between the connecting sleeve and the MPCVD equipment significantly sealed.
[0015] Thirdly, the anti-slip texture makes it easier for users to twist and adjust the ring cap.
[0016] Fourth, the auxiliary groove allows users to easily move the compression ring vertically. Attached Figure Description

Detailed Implementation
[0025] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0026] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, an observation window for an MPCVD device includes a connecting pipe 101. The top of the connecting pipe 101 has an annular placement groove 102 with openings at both the top and bottom. An observation window 103 is snapped into the annular placement groove 102. A first sealing ring 104 is snapped into and fixed at the bottom of the annular placement groove 102. A first mounting groove 105, adapted to the first sealing ring 104, is provided at the bottom of the annular placement groove 102. The annular placement groove 102 is vertically slidable. There is a pressure ring 106, and a second sealing ring 107 is snapped onto the bottom of the pressure ring 106. A second mounting groove 108 that matches the upper middle part of the second sealing ring 107 is provided at the bottom of the pressure ring 106. An annular cover 109 is screwed onto the inner side wall of the upper end of the annular placement groove 102. An annular pressure platform 110 that matches the pressure ring 106 is provided at the bottom of the annular cover 109. A connection module for connecting to the MPCVD equipment is provided at the bottom of the connecting pipe 101.
[0027] like Figure 1 As shown, the top of the annular cover 109 is provided with multiple rotating grooves 201. By rotating the grooves 201, the annular cover 109 can be easily adjusted.
[0028] like Figure 4 , 5As shown in Figure 6, a plurality of guide slide plates 301 adapted to the observation window 103 are provided on the inner side wall of the lower middle part of the annular placement groove 102, and a plurality of guide grooves 302 adapted to the corresponding guide slide plates 301 are provided on the side end of the pressure ring 106.
[0029] like Figure 1 , 2 As shown in Figure 3, the connection module includes a connecting sleeve 401 located at the bottom of the connecting tube 101. A third sealing ring 402 is fitted on the outer wall of the upper end of the connecting sleeve 401. An extension ring plate 403 is also provided at the bottom side of the connecting sleeve. Multiple connecting bolts 404 for screwing and fixing the MPCVD equipment are provided on the extension ring plate 403. The MPCVD equipment is provided with a connecting insertion hole that matches the connecting sleeve 401 and a threaded connection hole that matches the connecting bolts 404.
[0030] The user can first engage and fix the first sealing ring 104 with the first mounting groove 105, then engage and place the observation window 103 into the annular placement groove 102, ensuring that the bottom of the observation window 103 abuts against the top of the first sealing ring 104. Next, the user can engage and fix the second sealing ring 107 with the second mounting groove 108. Then, through the sliding engagement of the guide slide plate 301 and the guide groove 302, the user can place the pressure ring 106 into the annular placement groove 102, pressing the second sealing ring 107 against the pressure ring 106 and the observation window 104. Between the top of the window 103, the annular cap 109 can then be screwed and fixed to the upper end of the annular placement groove 102. During this process, the annular pressure plate 110 will apply a downward force to the pressure ring 106, the second sealing ring 107, the observation window 103 and the first sealing ring, so that the annular cap 109 is screwed and fixed to the upper inner wall of the annular placement groove 102. Through the cooperation of the first sealing ring 104 and the second sealing ring 107, the connection between the observation window 103 and the annular placement groove 102 has a significant sealing performance. Because the second sealing ring 107 is pressed down by the downward movement of the compression ring 106, the sealing at the connection between the compression ring 106, the second sealing ring 107, the observation window 103, and the first sealing ring 104 is sealed. Since the first sealing ring 104 and the second sealing ring 107 are not rotated, the first sealing ring 104 and the second sealing ring 107 can be effectively prevented from being damaged by rotation and deformation, and the sealing performance of the corresponding parts can be avoided.
[0031] Users can insert and fix the connecting sleeve 401 into the connecting socket, and make the third sealing ring 402 abut against the top outer wall of the MPCVD equipment. Then, multiple connecting bolts 404 can pass through the extension ring plate 403 and be screwed into the corresponding threaded connecting holes, thus flexibly fixing the connecting sleeve 401 and the MPCVD equipment together. The third sealing ring 402 provides a significant seal at the connection between the connecting sleeve 401 and the MPCVD equipment. Because the seal is achieved by vertically pressing the MPCVD equipment against the third sealing ring 402, without damaging the third sealing ring 402 through twisting, it better meets user needs.
[0032] According to another embodiment of the present invention, such as Figure 4 As shown, the side end of the annular pressure cap 109 is also provided with anti-slip texture 202. The anti-slip texture 202 makes it easier for users to adjust the annular pressure cap 109 by hand.
[0033] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, an auxiliary groove 111 is also provided on the inner sidewall of the middle part of the clamping ring 106. Through the auxiliary groove 111, the user can easily move the clamping ring 106 vertically.
[0034] An MPCVD apparatus includes an MPCVD apparatus viewing window 103 as described above.
[0035] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
