Description

Technical Field

[0001] This utility model relates to the field of laser technology, specifically to an improved structure for the emitting end of a high-efficiency CO2 glass laser. Background Technology

[0002] High-efficiency CO2 glass lasers use carbon dioxide gas as the main working substance. CO2 molecules have a specific energy level structure, which plays a key role in the laser generation process. It belongs to molecular gas lasers. When gas molecules are excited by energy, they will transition between different energy levels, thereby generating laser light.

[0003] The high-efficiency CO2 glass laser emitter is the output part of the laser beam, which acts like a "window" to emit the laser beam that has been amplified and oscillated in the resonant cavity. Its quality and performance directly affect the quality, power and characteristics of the laser output, so the emitter plays an important role in the device.

[0004] However, in the existing technology, carbon dioxide lasers are gas lasers. If the emitting end is not properly sealed, gas leakage will occur. Gas leakage will change the gas composition and pressure inside the laser. Carbon dioxide lasers require specific gas ratios and pressures to work properly. Gas leakage will reduce the laser gain, leading to unstable output power. Severe gas leakage will prevent the laser from working properly. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the shortcomings and defects of existing technologies, such as gas leakage if the transmitter head is not properly sealed, leading to unstable output power and, in severe cases, laser malfunction.

[0006] The present invention discloses an improved structure for the transmitter head of a high-efficiency CO2 glass laser, comprising a connector and a transmitter body. One end of the connector is provided with a support ring, and a groove is provided on the transmitter body at a corresponding position of the support ring. The support ring is inserted into the groove. A sealing ring one is provided on the inner side of the support ring, and a sealing ring two is provided on the outer side of the support ring. A fixing member is provided between the connector and the transmitter body.

[0007] Furthermore, the sealing ring one and the sealing ring two have the same structure, and the cross-section of the sealing ring one and the sealing ring two are both "L" shaped, and the sealing ring one and the sealing ring two are arranged opposite to each other.

[0008] Furthermore, one end of the support ring is threadedly connected to the connector, and a sealing ring three is provided between the connector and the support ring, with the sealing ring three installed on the connector.

[0009] Furthermore, the cross-section of the support ring is set in a "T" shape, and the end of the support ring near the transmitter body is chamfered.

[0010] Furthermore, the fixing component includes a positioning plate and a fixing plate. The fixing plate is installed on the transmitter body, one end of the positioning plate is installed on the connector, and the other end of the positioning plate passes through the space between the fixing plate and the transmitter body.

[0011] Furthermore, the fixing plate is provided with mounting holes, and a fixing bolt is provided inside the mounting holes. One end of the fixing bolt passes through the mounting holes and is threadedly connected to the positioning plate.

[0012] Furthermore, multiple positioning plates and fixing plates are provided, and the multiple positioning plates and fixing plates are evenly distributed on the corresponding connectors or transmitter bodies.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model comprises components such as a first sealing ring, a second sealing ring, and a support ring. The first sealing ring and the second sealing ring are positioned opposite each other. The first sealing ring prevents gas leakage, while the second sealing ring blocks external impurities from entering the laser. Together with the support ring, they form a sandwich structure. The middle support ring bears the main sealing pressure, ensuring the rigidity of the overall structure. The first and second sealing rings on both sides respectively block internal and external gases or impurities, providing excellent sealing performance under different operating conditions. This prevents gas leakage, which could cause unstable output power and affect the normal operation of the laser.

[0015] 2. This utility model, by incorporating components such as a sealing ring three, a positioning plate, a fixing bolt, and a fixing plate, improves the sealing effect by filling the gap between one end of the support ring and the connector during operation through the sealing ring three. By driving the support ring to rotate, the support ring can be removed from the connector, facilitating the replacement of sealing ring one and sealing ring two. The fixing plate component, positioning plate component, and fixing bolt component work together, and the fixing bolt fixes the position of the positioning plate and the fixing plate, thereby limiting the relative position between the connector and the transmitter body and ensuring the stability of the connection.

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figures 1-4 As shown, the improved structure of the high-efficiency CO2 glass laser transmitter end of this utility model includes a connector 1 and a transmitter body 2. One end of the connector 1 is provided with a support ring 3, which is made of nickel-based alloy. This type of alloy can maintain stable mechanical properties in high-temperature environments and has strong oxidation resistance, which can effectively resist the high-temperature oxidizing atmosphere near the end of the laser during operation and prevent the sealing performance from deteriorating due to oxidation. A groove 7 is provided on the transmitter body 2 at the corresponding position of the support ring 3, and the support ring 3 is inserted into the groove 7. A sealing ring 4 is provided on the inner side of the support ring 3, and a sealing ring 5 is provided on the outer side of the support ring 3. A fixing component is provided between the connector 1 and the transmitter body 2. Both the sealing ring 4 and the sealing ring 5 are made of fluororubber, which can withstand the corrosive gases that may exist in the laser and the chemical corrosion caused by coolant leakage.

[0024] Combination Figure 3 , Figure 4 As shown, sealing ring 4 and sealing ring 5 have the same structure. The cross-section of sealing ring 4 and sealing ring 5 is "L" shaped. Sealing ring 4 and sealing ring 5 are arranged opposite to each other. Compared with a single layer arrangement, the combination of sealing ring 4 and sealing ring 5 can effectively improve the sealing performance. When one of sealing ring 4 or sealing ring 5 is damaged, the other can still maintain a good sealing effect.

[0025] In this embodiment, one end of the support ring 3 is threaded to the connector 1, and a sealing ring 3 6 is provided between the connector 1 and the support ring 3. The sealing ring 3 6 is installed on the connector 1, and the gap between one end of the support ring 3 and the connector 1 is filled by the sealing ring 3 6, thereby further improving the sealing effect.

[0026] In this embodiment, the cross-section of the support ring 3 is set to a "T" shape, which restricts the position of the sealing ring 4 and the sealing ring 5 during installation, thereby improving the convenience of installation. The end of the support ring 3 near the transmitter body 2 is chamfered to facilitate the connection between the support ring 3 and the groove 7.

[0027] Looking back Figure 1 , Figure 2 As shown, the fastener includes a positioning plate 9 and a fixing plate 8. The fixing plate 8 is installed on the transmitter body 2. One end of the positioning plate 9 is installed on the connector 1. The other end of the positioning plate 9 passes between the fixing plate 8 and the transmitter body 2. The end of the positioning plate 9 away from the connector 1 is chamfered.

[0028] In this embodiment, the fixing plate 8 is provided with a mounting hole 11, and a fixing bolt 10 is provided inside the mounting hole 11. One end of the fixing bolt 10 passes through the mounting hole 11 and is threadedly connected to the positioning plate 9. The fixing bolt 10 restricts the position of the positioning plate 9 and the fixing plate 8, thereby indirectly restricting the relative position between the connector 1 and the transmitter body 2.

[0029] In this embodiment, multiple positioning plates 9 and fixing plates 8 are provided. The multiple positioning plates 9 and fixing plates 8 are evenly distributed on the corresponding connector 1 or transmitter body 2. When assembling the connector 1 and the transmitter body 2, the multiple fixing bolts 10 are tightened in a cross-step manner to avoid sealing gaps due to uneven local force and to ensure the integrity and consistency of the seal.

[0030] The implementation principle is as follows: During use, sealing ring 4 prevents gas leakage, and sealing ring 5 blocks external impurities from entering the laser, thus achieving efficient sealing. When sealing ring 4 and sealing ring 5 need to be replaced, the fixing bolt 10 is rotated by disassembly, so that the fixing bolt 10 and the positioning plate 9 are removed, thereby releasing the restriction on the positioning plate 9 and indirectly releasing the fixation between the transmitter body 2 and the connector 1. Then, the connector 1 is driven to move off the transmitter body 2. Next, the support ring 3 is rotated and removed from the connector 1. Sealing ring 4 and sealing ring 5 move with it. Then, sealing ring 4 and sealing ring 5 can be removed and replaced. Installation is carried out by reversing the operation.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
