Description

Technical Field

[0001] This utility model relates to the field of laser installation technology, and in particular to an integral cylindrical shell for a laser and a laser. Background Technology

[0002] As precision optoelectronic devices, gas lasers are extremely sensitive to external environmental disturbances (such as mechanical vibration, temperature fluctuations, dust, and contaminants) in their core internal components (e.g., gain medium, resonant cavity, optical lenses). To ensure stable and reliable operation of the laser in complex industrial environments or experimental conditions, a rigid outer shell is typically installed around it. The laser tube is fixedly mounted inside the shell by a support structure. The laser tube is protected and dustproofed by the shell, which also serves as the interface for mechanical connection and integration between the laser tube and external racks, equipment, or systems.

[0003] In existing technologies, due to considerations such as uniform heat dissipation, structural strength, and processability, monolithic laser housings often adopt simple geometric shapes, with cylindrical (i.e., cylindrical) housings being particularly common. However, when a cylindrical structure is used, due to the circumferential curved surface characteristics of the cylindrical housing, it cannot be directly and stably fixed to the frame via a flat surface, posing challenges to its installation with external equipment. Utility Model Content

[0025] Example 1 like Figure 1 , Figure 2 As shown, an integral cylindrical laser housing includes a cylindrical housing 1, a mounting plate 3, a grooved plate 4, a bottom plate 5, and a connector 6. The mounting plate 3 is movably disposed inside the housing 1 and arranged longitudinally along the housing 1. The mounting plate 3 is used to fix the laser tube 2, for example, by binding or clamping. The mounting plate 3, grooved plate 4, and bottom plate 5 are arranged sequentially from top to bottom at the bottom of the housing 1. The two side plates of the grooved plate 4 contact the housing 1, i.e., the opening of the groove in the grooved plate 4 faces the side where the housing 1 is located. The housing 1 is placed on the grooved plate 4. The groove is in contact with the side plates on both sides, so that the curved side wall of the cylindrical shell 1 can be laterally limited by the side plates on both sides of the groove plate 4; the bottom plate 5 is located at the bottom of the groove plate 4, and the opposite sides of the bottom plate 5 extend beyond the groove plate 4 to form the mounting part 51 for mounting with the frame equipment 9. The bottom plate 5 can extend beyond the groove plate 4 on both sides laterally or on both sides of the bottom plate 5, and is not limited to the above examples; the mounting plate 3, the shell 1, the groove plate 4 and the bottom plate 5 are fixedly connected in sequence by the connector 6 and integrated into one body.

[0026] In the above scheme, the mounting plate 3, the outer shell 1, the groove plate 4 and the base plate 5 are set separately, and each component can be disassembled from each other and connected into one unit by the connector 6.

[0027] In this embodiment, the connector 6 is preferably a bolted component, which has a simple structure, is easy to use, and has a reliable connection. The mounting plate 3, the outer shell 1, the groove plate 4, and the base plate 5 can be disassembled and replaced with each other.

[0028] In this embodiment, both the mounting plate 3 and the base plate 5 are preferably elongated plates. The lateral sides of the mounting plate 3 abut against the inner wall of the outer shell 1, and the middle of the mounting plate 3 has a row of threaded holes along the longitudinal direction for threaded engagement with the connector 6 that passes through the bottom of the base plate 5, facilitating installation. The lateral sides of the base plate 5 extend beyond the corresponding sides of the slot plate 4, and the longitudinal ends of the base plate 5 are flush with the ends of the slot plate 4 and also flush with the ends of the outer shell 1. The base plate 5 has through holes for the connector 6 to pass through. These through holes can be smooth holes, threaded holes, elongated slots, etc., and are preferably countersunk smooth holes. The countersunk slots are located at the bottom of the base plate 5, facilitating the quick insertion and installation of the connector 6 from the bottom, especially when the laser tube is fixedly installed with the mounting plate 3 and there are a large number of connectors 6. Correspondingly, the slot plate 4 and the outer shell 1 also have corresponding through holes for the connector 6 to pass through, preferably spaced along the longitudinal direction, which is beneficial for better lateral and longitudinal force transmission.

[0029] In an optional embodiment, multiple connectors 6 are arranged longitudinally at intervals to improve the connection strength between the outer shell 1 and the base plate 5, which can effectively prevent misalignment and has high overall strength.

[0030] In an optional embodiment, the outer shell 1 is made of a non-metallic material, such as engineering plastic, ceramic or composite material, preferably plastic, which has excellent electrical insulation properties, can effectively prevent leakage risk and protect users from electric shock, and has low loss, is lightweight and portable and low cost.

[0031] As another possible implementation, the housing 1 can also be made of metal, which has better heat dissipation capacity, structural strength and electromagnetic shielding performance, and is more suitable for high temperature environments.

[0032] In an optional embodiment, the mounting plate 3 is slidably connected to the outer casing 1. For example, sliding grooves are provided on the inner walls of both sides of the outer casing 1, and the sliding grooves slide in engagement with the mounting plate 3 to limit the vertical and lateral displacement of the mounting plate 3.

[0033] As another possible implementation, the inner wall of the outer shell 1 can be made into a smooth curved surface, and the mounting plate 3 can be placed directly on the inner wall of the outer shell 1 and connected and fixed by the connector 6. Alternatively, the outer shell 1 can be clamped by the pre-tightening force of the connector 6 and the mounting plate 3 to achieve limiting.

[0034] To achieve fixed installation of the base plate 5 and the frame equipment 9, in an optional embodiment, multiple mounting holes (not shown in the figure) can be provided at intervals on the mounting portions 51 on both sides of the base plate 5. The mounting holes are fixedly connected to the frame equipment 9 by fastening devices 8, such as bolts and screws; or, as... Figures 3-5As shown, a pressure block 7, which mates with the mounting part 51, is connected to the frame device 9. The pressure block 7 and the frame device 9 are detachably connected by a fastening device 8. A small gap is reserved between the pressure block 7 and the frame device 9. The clamping force of the pressure block 7 and the frame device 9 on the mounting part 51 is adjusted by the fastening device 8 to fix the mounting part 51. This can better adapt to working conditions where the distance between the holes of the frame device 9 and the mounting part 51 is mismatched. To better limit the mounting part 51 with the pressure block 7, a positioning part, such as a protrusion or groove structure, can also be provided on the mounting hole. The positioning part mates with the pressure block 7, thereby fixing the outer shell 1 to the frame device 9 through the mounting part 51. This is not limited to the above example.

[0035] In use, the laser tube 2 is first fixedly installed on the long strip mounting plate 3. After installation, it slides into the cylindrical outer shell 1 and clamps with the outer base plate 5 and slot plate 4. Then, it is pressed tightly with the connector 6. The plastic cylindrical outer shell 1 is clamped by the slot plate 4 and the mounting plate 3, and both ends are sealed with cover plates. The resulting integral cylindrical laser shell has good overall strength and rigidity, and features insulation, dustproofing, and convenient installation. In addition, the slot plate 4 with different heights can be replaced, or the base plate 5 or mounting plate 3 with different thicknesses can be used to adjust the installation height between the outer shell 1 and the frame equipment 9, according to the requirements of the operating conditions.

[0036] As another possible implementation, the aforementioned groove plate 4 and bottom plate 5 can also be integrated, such as by using an integral molding structure or by welding, hot melting, or other methods. The cylindrical outer shell 1 can then be fixed to the mounting plate 3 by means of the connecting piece 6 and the clamping outer shell 1, thereby reducing the number of assembly parts and improving installation efficiency.

[0037] Example 2 Based on Embodiment 1, this embodiment provides a laser, including any of the above-described integral laser cylindrical housings, with a laser tube 2 disposed inside the housing 1. The laser tube 2 disposed inside the housing 1 can be a low-power single carbon dioxide laser tube 2, or it can be a folded tube style.

[0038] The aforementioned monolithic cylindrical housing for lasers is preferably used in folded tube mounting, for example, as... Figure 1 As shown, the folded tube in this embodiment includes three laser tube units arranged side by side and connected in series via U-shaped bends. The three laser tube units are arranged in a triangular pattern, with each pair in contact and mutually fixed. The folded tube is adapted to the inner wall dimensions of the outer shell 1, meaning all three laser tube units in the folded tube are in contact with the inner wall of the outer shell 1. This results in high structural rigidity and overall high stability and vibration resistance. Folded tubes are existing technology, and their specific structure and working principle will not be elaborated further. The number of laser tube units and the folding method are not limited to the examples described above.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
