Description

Technical Field

[0001] The utility model belongs to the technical field of solid lasers, and in particular relates to a glue-free laser rod sleeve. Background Art

[0002] The laser rod (such as Nd:YAG crystal) in the xenon lamp (or krypton lamp) pumped solid-state laser is the main core component, with a high-pressure gas discharge lamp as the pump source, and they are packaged together in a sealed cavity with a certain reflection and convergence function. However, since the xenon lamp is a high-pressure gas discharge lamp, a large amount of waste heat will be generated when it is working. If it cannot be discharged in time, the xenon lamp and the crystal rod may explode due to the accumulation of a large amount of waste heat, resulting in equipment damage and economic losses. Therefore, the cavity must be cooled by circulating coolant to protect the components and stabilize its working state. The length of the laser rod is generally much smaller than the length of the gas lamp. In order to maintain the sealing of the cavity after installation, the length will be supplemented by bonding the support rod sleeve to facilitate sealing installation. However, the sealing adhesive bonding has certain technical requirements, and it takes a long time to work, and it is inconvenient to remove the support rod sleeve and the laser rod for routine optical maintenance. Utility Model Content

[0003] In view of the above-mentioned deficiencies, the utility model provides a glue-free laser rod sleeve, which is achieved by screwing the rod sleeve buckle to the outside of the mounting tube of the supporting rod sleeve so that the mounting tube and the rod sleeve buckle jointly squeeze the rubber sealing ring. The rubber sealing ring is squeezed and deformed to clamp and fix the laser rod located in the first assembly hole and the second assembly hole, thereby improving the sealing performance between the laser rod and the supporting rod sleeve.

[0004] The utility model is realized by the following technical solutions:

[0005] A glue-free laser rod sleeve comprises a supporting rod sleeve and a rod sleeve buckle. The supporting rod sleeve comprises a sleeve and a mounting sleeve protruding from the sleeve, the outer diameter of the mounting sleeve is smaller than the outer diameter of the sleeve, the outer wall of the mounting sleeve is provided with an external thread, and the interior of the mounting sleeve is provided with a first assembly hole. A coaxial mounting groove, a gasket groove and a second assembly hole are provided on the inner side of the rod sleeve buckle, an internal thread matching the external thread is provided in the mounting groove, a rubber sealing ring is provided in the gasket groove, the second assembly hole has the same aperture as the first assembly hole, the rubber sealing ring is elastic, and when the rubber sealing ring is in a free state, the thickness of the rubber sealing ring is greater than the depth of the gasket groove. Both the first assembly hole and the second assembly hole are clearance-matched with the laser rod. The rod sleeve buckle is screwed to the mounting sleeve to squeeze the rubber sealing ring, and the rubber sealing ring is deformed to clamp and fix the laser rod.

[0006] Furthermore, an expansion hole connected to the second assembly hole is provided on the inner side of the rod sleeve buckle, and the minimum inner diameter of the expansion hole is consistent with the inner diameter of the second assembly hole, and the inner diameter of the expansion hole gradually increases in the direction close to the laser rod, so as to facilitate the laser rod to extend into the rod sleeve buckle and the supporting rod sleeve.

[0007] Furthermore, when the rubber sealing ring is in a free state, the outer diameter of the rubber sealing ring is consistent with the inner diameter of the gasket groove, and the inner diameter of the rubber sealing ring is consistent with the inner diameter of the second assembly hole, ensuring that the rubber sealing ring can deform more toward the direction of the laser rod when deformed, thereby improving the sealing performance between the rubber sealing ring and the laser rod.

[0008] Furthermore, a heat dissipation hole is opened on the inner side of the sleeve, and the inner diameter of the heat dissipation hole is larger than the inner diameter of the first assembly hole, thereby increasing the heat dissipation capacity of the laser rod and reducing the hindering effect of the support rod sleeve on the heat dissipation of the laser rod.

[0009] Furthermore, a heat dissipation hole is opened on the inner side of the mounting tube, and the inner diameter of the heat dissipation hole is larger than the inner diameter of the first assembly hole, thereby increasing the heat dissipation capacity of the laser rod and reducing the hindering effect of the support rod sleeve on the heat dissipation of the laser rod.

[0010] Furthermore, the support rod sleeve also includes a connecting tube fixed to the sleeve, and the connecting tube is located on a side of the sleeve away from the mounting tube, so as to facilitate the installation of the support rod sleeve in the solid-state laser device.

[0011] Furthermore, the inner side of the rod sleeve buckle is coated with a Teflon coating, which has a low friction coefficient and good wear resistance. Coating the Teflon coating on the inner side of the rod sleeve buckle helps the laser rod to penetrate into the second assembly hole on the inner side of the rod sleeve buckle.

[0012] Furthermore, the support rod sleeve and the rod sleeve buckle are both made of stainless steel, so that the support rod sleeve and the rod sleeve buckle have good corrosion resistance.

[0013] Beneficial effects of the utility model:

[0014] By screwing the rod sleeve buckle to the outside of the mounting tube of the supporting rod sleeve, the mounting tube and the rod sleeve buckle jointly squeeze the rubber sealing ring, and the rubber sealing ring is squeezed and deformed to clamp and fix the laser rod located in the first assembly hole and the second assembly hole, thereby improving the sealing performance between the laser rod and the supporting rod sleeve.

[0026] like Figures 1 to 5A glue-free laser rod sleeve is shown, comprising a supporting rod sleeve 1 and a rod sleeve buckle 2. The supporting rod sleeve 1 comprises a sleeve 11 and a mounting tube 12 protruding from the sleeve 11, wherein the outer diameter of the mounting tube 12 is smaller than the outer diameter of the sleeve 11, an outer wall of the mounting tube 12 is provided with an external thread 121, and a first assembly hole 122 is provided inside the mounting tube 12. A coaxial mounting groove 21, a gasket groove 22 and a second assembly hole 23 are provided inside the rod sleeve buckle 2, an internal thread 211 matching the external thread 121 is provided inside the mounting groove 21, a rubber sealing ring is provided inside the gasket groove 22, the second assembly hole 23 has the same aperture as the first assembly hole 122, the rubber sealing ring is elastic, and when the rubber sealing ring is in a free state, the thickness of the rubber sealing ring is greater than the depth of the gasket groove 22. The first assembly hole 122 and the second assembly hole 23 are both clearance-matched with the laser rod 3. The rod sleeve buckle 2 is screwed to the mounting tube 12 to squeeze the rubber sealing ring, and the rubber sealing ring is deformed to clamp and fix the laser rod 3.

[0027] In one embodiment, first, the rubber sealing ring is filled into the gasket groove 22 of the rod sleeve buckle 2. Then the rod sleeve buckle 2 is screwed to the supporting rod sleeve 1, specifically, the mounting groove 21 of the rod sleeve buckle 2 is sleeved to the outside of the mounting tube 12 of the supporting rod sleeve 1, and the internal thread 211 of the mounting groove 21 cooperates with the external thread 121 of the mounting tube 12. It should be noted that the rod sleeve buckle 2 does not need to be tightened to the mounting tube 12, that is, at this time, it is necessary to ensure that the side wall of the mounting tube 12 is not in contact with the rubber sealing ring, and the rubber sealing ring is in a free state. Then, the laser rod 3 is sequentially passed through the second assembly hole 23 of the rod sleeve buckle 2, the inner hole of the rubber sealing ring and the first assembly hole 122 of the supporting rod sleeve 1. Since the inner diameters of the first assembly hole 122 and the second assembly hole 23 are consistent, the laser rod 3 and the first assembly hole 122 are clearance-matched, so the laser rod 3 can be slid in the axial direction of the supporting rod sleeve 1 to adjust the axial position of the laser rod 3 relative to the supporting rod sleeve 1, which is convenient for adjusting the position of the laser rod 3. After the adjustment is completed, continue to screw the rod sleeve buckle 2 to move the rod sleeve buckle 2 toward the supporting rod sleeve 1, so that the side wall of the mounting tube 12 squeezes the rubber sealing ring in the gasket groove 22, the rubber sealing ring is deformed, and the inner hole diameter of the rubber sealing ring is reduced until the rubber sealing ring is squeezed to the laser rod 3, thereby achieving the extrusion and fixation of the laser rod 3 by the rubber sealing ring.

[0028] Preferably, the inner side of the rod sleeve buckle 2 is further provided with an expanded hole 24 connected to the second assembly hole 23, the minimum inner diameter of the expanded hole 24 is consistent with the inner diameter of the second assembly hole 23, and the inner diameter of the expanded hole 24 gradually increases in the direction close to the laser rod 3, so as to facilitate the laser rod 3 to extend into the rod sleeve buckle 2 and the support rod sleeve 1.

[0029] Preferably, when the rubber sealing ring is in a free state, the outer diameter of the rubber sealing ring is consistent with the inner diameter of the gasket groove 22, and the inner diameter of the rubber sealing ring is consistent with the inner diameter of the second assembly hole 23, ensuring that the rubber sealing ring can deform more toward the direction of the laser rod 3 when deformed, thereby improving the sealing performance between the rubber sealing ring and the laser rod 3.

[0030] In one embodiment, a rubber sealing ring is selected to cooperate with the gasket groove 22 so that when the rubber sealing ring is squeezed by the side wall of the mounting tube 12 , the rubber sealing ring is deformed mainly toward the inside, which helps the rubber sealing ring to squeeze and fix the laser rod 3 .

[0031] Preferably, a heat dissipation hole 111 is opened on the inner side of the sleeve 11 , and the inner diameter of the heat dissipation hole 111 is larger than the inner diameter of the first assembly hole 122 , thereby increasing the heat dissipation capacity of the laser rod 3 and reducing the hindering effect of the support rod sleeve 1 on the heat dissipation of the laser rod 3 .

[0032] It should be noted that the inner diameter of the first assembly hole 122 is slightly larger than the outer diameter of the laser rod 3, that is, the rubber seal ring is slightly deformed, so that the rubber seal ring can squeeze and fix the laser rod 3. The inner diameter of the heat dissipation hole 111 is much larger than the outer diameter of the laser rod 3, and there is an annular heat dissipation area between the laser rod 3 and the inner wall of the heat dissipation hole 111, which is helpful for heat dissipation of the laser rod 3.

[0033] Preferably, a heat dissipation hole 111 is opened on the inner side of the mounting tube 12 , and the inner diameter of the heat dissipation hole 111 is larger than the inner diameter of the first assembly hole 122 , thereby increasing the heat dissipation capacity of the laser rod 3 and reducing the hindering effect of the support rod sleeve 1 on the heat dissipation of the laser rod 3 .

[0034] Preferably, the support rod sleeve 1 further comprises a connecting tube 13 fixed to the sleeve 11, and the connecting tube 13 is located on a side of the sleeve 11 away from the mounting tube 12, so as to facilitate the installation of the support rod sleeve 1 in the solid-state laser device. It should be noted that the connecting tube 13 is a conventional setting, and is mainly used for the connection and installation of the support rod sleeve 1 and the solid-state laser device. The structure of the connecting tube 13 is not described in detail.

[0035] Preferably, the inner side of the rod sleeve buckle 2 is coated with a Teflon coating, which has a low friction coefficient and good wear resistance. Coating the Teflon coating on the inner side of the rod sleeve buckle 2 helps the laser rod 3 to penetrate into the second assembly hole 23 on the inner side of the rod sleeve buckle 2.

[0036] Preferably, the support rod sleeve 1 and the rod sleeve buckle 2 are both made of stainless steel, so that the support rod sleeve 1 and the rod sleeve buckle 2 have good corrosion resistance.

[0037] When the above-mentioned glue-free laser rod sleeve is used, the rod sleeve buckle 2 is screwed to the outside of the mounting tube 12 of the supporting rod sleeve 1 so that the mounting tube 12 and the rod sleeve buckle 2 jointly squeeze the rubber sealing ring, and the rubber sealing ring is squeezed and deformed to clamp and fix the laser rod 3 located in the first assembly hole 122 and the second assembly hole 23, thereby improving the sealing performance between the laser rod 3 and the supporting rod sleeve 1.

[0038] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
