Description

Technical Field

[0001] This application relates to the technical field of laser tube support, and in particular to a novel laser tube support structure. Background Technology

[0002] Currently, most laser brackets in existing technologies use rigid metal sleeves or clamping mechanical structures to fix the laser tube. For example, in some carbon dioxide lasers or semiconductor laser modules, the laser tube is directly inserted into a metal sleeve and then clamped and fixed by lateral screws; or a rigid clamping block is used in conjunction with bolts to clamp the tube from the outside to achieve positioning and installation.

[0003] However, the rigid sleeve and the outer wall of the laser tube usually rely only on clearance fit or local compression, lacking an effective dynamic sealing structure. This makes it easy for external dust and moisture to enter the laser chamber, contaminating the optical end face or the medium inside the chamber, thus affecting the stability and service life of the laser output.

[0004] Therefore, a new type of laser tube support structure is urgently needed to solve the above problems.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Utility Model Content

[0006] The main objective of this application is to provide a novel laser tube support structure that solves the problem of poor sealing of existing laser tube support structures, which easily leads to dust entering the laser cavity and affecting the stability of laser output.

[0007] To achieve the above objectives, this application provides a novel laser tube support structure, comprising: a fixed base, wherein the fixed base has a placement cavity for placing the laser tube, and a sealing ring is provided in the placement cavity to form a seal with the outer wall of the laser tube; One end of the fixed base is connected to a flange, and a pressure block and an annular rubber gasket are provided inside the flange. The annular rubber gasket is located on one side of the pressure block. The pressure block is connected to the front end of the laser tube, and the end face of the front end of the laser tube is in contact with the annular rubber gasket.

[0008] As a preferred embodiment of this application, a first groove is provided on the flange, the pressure block is disposed in the first groove, a second groove is provided in the first groove that penetrates the flange, and the annular rubber gasket is disposed in the second groove.

[0009] As a preferred embodiment of this application, it also includes a slot, wherein the placement cavity has a slot and the sealing ring is disposed in the slot.

[0010] As a preferred embodiment of this application, the fixing base is a cylindrical pipe with a plurality of pin holes radially distributed on the cylindrical pipe. The plurality of pin holes penetrate the placement cavity and are provided with plastic pins in the plurality of pin holes.

[0011] As a preferred embodiment of this application, the number of sealing rings is two, and the two sealing rings are located at both ends of the fixing base.

[0012] As a preferred embodiment of this application, one end of the fixing seat is provided with a connecting seat, and the connecting seat is provided with a plurality of screw posts, and the fixing seat is connected to the flange through the plurality of screw posts.

[0013] As a preferred embodiment of this application, the first groove and the second groove are circular grooves, and the diameter of the first groove is larger than the diameter of the second groove.

[0014] As a preferred embodiment of this application, the pressing block is composed of two semi-circular ring blocks.

[0015] As a preferred embodiment of this application, the two semi-circular annular blocks are provided with arc-shaped grooves.

[0016] This application provides a novel laser tube support structure that utilizes a sealing ring placed inside the cavity to form a radial dynamic seal with the outer wall of the laser tube, preventing external dust and moisture from intruding from the tail end.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 In one embodiment, a novel laser tube support structure includes: a fixing base 1, on which a placement cavity for placing a laser tube 3 is provided, and a sealing ring that forms a seal with the outer wall of the laser tube 3 is provided in the placement cavity; One end of the fixed base 1 is connected to a flange 2. Inside the flange 2, a pressure block 4 and an annular rubber gasket 5 are installed. The annular rubber gasket 5 is located on one side of the pressure block 4. The pressure block 4 is connected to the front end of the laser tube 3. The end face of the front end of the laser tube 3 is in contact with the annular rubber gasket 5. The annular rubber gasket 5 is specifically made of fluororubber. During installation, the fluororubber gasket, laser tube 3, pressure block 4 and sealing ring are placed in sequence. The pressure block 4 and screws are used to achieve rigid fixation, while the elasticity and friction of the sealing ring are used to assist in positioning.

[0022] Furthermore, a connecting seat 10 is provided at one end of the fixed seat 1, and a number of screw posts 11 are provided on the connecting seat 10. The fixed seat 1 is connected to the flange 2 through the number of screw posts 11.

[0023] Furthermore, it also includes a slot 8, which is provided in the placement cavity, and the sealing ring is located in the slot 8; preferably, in this embodiment, there are two sealing rings, which are located at both ends of the fixing base 1. It can be understood that the mounting base provides an overall installation reference, and the slot 8 is used to position the sealing ring, thereby achieving the initial positioning of the laser tube 3; at the same time, the laser tube 3 is elastically clamped to achieve airtight sealing and prevent dust from entering the optical cavity.

[0024] It is understood that this application utilizes a sealing ring placed inside the cavity to form a radial dynamic seal with the outer wall of the laser tube 3, preventing external dust and moisture from intruding from the tail end. Simultaneously, an annular rubber gasket 5 is installed inside the flange 2 end, allowing it to axially and flexibly fit against the optical end face of the laser tube 3, forming an end face seal. Through these two sealing structures, a reliable sealed environment is provided for the laser tube 3 chamber, improving the laser's anti-contamination capability and reliability under harsh operating conditions, thereby directly ensuring stable laser output and extending its service life. Specifically, please refer to Figure 2 , Figure 3 , Figure 4 Based on the above embodiment, a first groove 6 is provided on the flange 2, and the pressure block 4 is located in the first groove 6. A second groove 7 penetrating the flange 2 is provided in the first groove, and an annular rubber gasket 5 is provided in the second groove 7. More specifically, the first groove 6 and the second groove 7 are circular grooves, and the diameter of the first groove 6 is larger than the diameter of the second groove 7. By setting the first groove 6 and the second groove 7, the pressure block 4 and the annular rubber gasket 5 can be effectively limited.

[0025] Specifically, please refer to Figure 1 Based on the above embodiment, the fixing seat 1 is a cylindrical pipe with multiple pin holes 9 radially distributed on the cylindrical pipe. The multiple pin holes 9 penetrate the placement cavity and are provided with plastic pins.

[0026] It is understandable that the installation angle of the laser tube 3 can be adjusted by using the pin hole 9 and the plastic pin to ensure the optical axis alignment. Specifically, by radially screwing the plastic pin into the placement cavity, its end will make flexible contact with the outer wall of the laser tube 3 and apply a controllable lateral force. When the screwing depth of the pin in different pin holes 9 is adjusted, the force exerted on the laser tube 3 at each contact point will be different, thereby slightly pushing the tube body to deflect within the placement cavity, realizing the fine adjustment of the angle around the axis. Through this adjustment method, the operator can precisely correct the direction of the laser tube 3, and ultimately ensure that its optical axis is accurately aligned with the external optical system.

[0027] Specifically, please refer to Figure 3 , Figure 4Based on the above embodiment, the pressure block 4 is composed of two semi-circular ring blocks, and screw holes are provided on the two semi-circular ring blocks. The screw holes are used to connect with the flange 2. Furthermore, arc-shaped grooves are provided on the two semi-circular ring blocks. The arc-shaped grooves are used to accommodate the front end face of the mechanism tube and play a role in limiting the front end face.

[0028] In summary, it can be understood that a novel laser tube support structure includes a fixing seat 1, which is a cylindrical tube with a placement cavity for placing the laser tube 3. A slot 8 is provided in the placement cavity, and two sealing rings are provided in the slot 8, located at both ends of the fixing seat 1 respectively. They are tightly fitted with the outer wall of the laser tube 3 to form an effective seal. One end of the fixed base 1 is provided with a connecting base 10, and several screw posts 11 are distributed on the connecting base 10. The structure also includes a flange 2, which is fastened to the screw posts 11 of the fixed base 1 through the screw holes on it. The flange 2 has concentric circular grooves of different diameters inside. The second groove 7 with a smaller diameter is embedded with an annular fluororubber gasket, while the first groove 6 with a larger diameter is equipped with a pressure block 4. The pressure block 4 is composed of two semi-circular annular blocks with screw holes, which are fixed to the flange 2 by screws, and an arc groove is opened on its inner side to accommodate the front end of the laser tube 3. During installation, first, the fluororubber gasket is placed into the groove of flange 2, followed by the laser tube 3, ensuring its front end is tightly fitted against the fluororubber gasket. Then, the pressure block 4 and the sealing ring are installed in sequence. Rigid fixation is achieved by tightening the screws on the pressure block 4, while the elasticity and friction of the sealing ring assist in positioning. In addition, multiple radial pin holes 9 are distributed circumferentially on the wall of the cylindrical fixing seat 1. The pin holes 9 extend into the placement cavity, and plastic pins can be inserted into the holes. By adjusting the advance and retreat of these plastic pins, the installation angle of the laser tube 3 can be finely adjusted, thereby ensuring precise alignment of the optical axis. This support structure forms a multi-layered dynamic seal at the front and rear ends through sealing rings and fluororubber gaskets, completely blocking the intrusion of external dust and moisture, effectively solving the problem of contamination in the optical chamber; at the same time, it combines the rigid fixation of the pressure block 4 with the precise angle adjustment of the pin, ensuring optical path collimation while achieving firm positioning, thereby significantly improving the long-term stability and service life of laser output.
