Description

Technical Field

[0001] This utility model relates to the field of gas laser technology, and in particular to an integral housing and quick-installation carbon dioxide laser. Background Technology

[0002] Carbon dioxide lasers have been widely used in industry, military, medical, and scientific research due to their high power, high energy conversion efficiency, and rich spectral lines (dozens of lines around 10 micrometers). To improve the structural stability and ease of installation of lasers, existing technologies have proposed integrated housing structures, such as the "Integrated Housing for Housing a Carbon Dioxide Laser" disclosed in Chinese Patent CN209929667U. This housing includes components such as a cylinder, support plate, bracket, and fastening devices, allowing for pre-assembly and calibration of the laser and housing in the factory, reducing on-site installation and debugging time, improving installation efficiency, and lowering costs.

[0003] However, this existing structure still has certain shortcomings in practical applications: such as Figure 1 As shown, the outer shell 1 typically has end caps 2 at both ends, with a light-passing hole 31 in the middle of the end cap 2 for the laser beam to pass through. When installing, replacing, or cleaning optical components such as dustproof lenses and output lenses at the laser tube end, the entire end cap must be removed from the shell. This cumbersome process not only increases assembly time and workload but may also lead to a decrease in the connection accuracy between the end cap and the shell due to frequent disassembly and installation, potentially causing thread stripping or structural loosening. More importantly, reinstalling the end cap may require recalibrating the optical path, severely affecting the stability and beam quality of the laser output, reducing user experience and maintenance efficiency.

[0004] Therefore, there is an urgent need in the field to improve existing monolithic housings to facilitate the installation and maintenance of laser tube end lenses. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the end cap of the integral housing of the carbon dioxide laser in the prior art, which makes it inconvenient to install and maintain the lens. It provides an integral housing and a quick-install carbon dioxide laser, which allows for convenient operation of the lens at the end of the laser tube without disassembling the entire end cap, thus significantly improving assembly and maintenance efficiency.

[0006] In a first aspect, the present invention provides an integral housing, including a cylindrical body and an end cap, the cylindrical body and the end cap being fixed by screws, the end cap having a lens mounting hole for inserting a hand or tool for operation, and a positioning structure on the side of the end cap opposite to the cylindrical body; it also includes an outer decorative panel, the outer decorative panel being magnetically attracted and fixed to the end face of the end cap, the outer decorative panel having a light-transmitting hole for a laser beam to pass through, and the outer decorative panel cooperating with the positioning structure to achieve radial positioning.

[0007] In the above solution, the outer decorative panel is fixed to the end cap by magnetic adsorption. This can be achieved by making both the outer decorative panel and the end cap from mutually attractive materials, allowing direct adsorption during use; alternatively, a magnetic adsorption element can be partially installed on one component of the outer decorative panel and the end cap, while the other component is made of a magnetically attractive material; or both components can have magnetic adsorption elements at specific locations, achieving magnetic adsorption and fixation through magnet-to-magnet or magnet-adsorption of pre-embedded magnetic conductive sheets. Magnetic connection between the end cap and the outer decorative panel facilitates quick and easy installation and removal of the outer decorative panel.

[0008] In the above solution, the outer decorative panel cooperates with the positioning structure to achieve radial positioning. This can be achieved by the outer contour of the entire outer decorative panel engaging with the positioning structure on the back of the end cap, such as embedding the entire outer decorative panel into the positioning structure. Alternatively, a mating structure can be provided on the side of the outer decorative panel facing the end cap. The mating structure engages with the positioning structure, such as the engagement of a positioning post and a positioning hole, or a flange and a step, to achieve radial positioning of the outer decorative panel. Radial positioning ensures that the optical center of the lens is precisely aligned with the center of the laser tube, guaranteeing the output performance of the laser.

[0009] The magnetic attraction structure and the positioning structure can be integrated or installed separately.

[0010] Preferably, the positioning structure is a positioning post, which is spaced apart along the circumference, and the outer decorative panel is provided with positioning holes along the circumference, and the positioning post is inserted into the positioning hole.

[0011] Preferably, the positioning structure is a positioning protrusion, and the outer decorative panel has a groove on the side facing the end cap that mates with the positioning protrusion.

[0012] Preferably, the outer decorative panel is provided with a magnetic adsorption member on the side facing the end cap, and the outer decorative panel is magnetically adsorbed and fixed to the end face of the end cap by the magnetic adsorption member.

[0013] Preferably, the magnetic adsorption element is a permanent magnet, and the end cap is made of a material that can be attracted by magnetic force.

[0014] Preferably, the magnetic adsorption component is a permanent magnet, and a magnetic conductive sheet or a second permanent magnet corresponding to the position of the permanent magnet is embedded or fixed on the end face of the end cap.

[0015] Preferably, the outer decorative panel has one or more handle grooves or lugs on the side opposite to the end cap to facilitate the operator to apply force.

[0016] Preferably, the outer decorative panel has an circumferential flange on the side opposite to the end cap on the outer periphery of the light-transmitting hole.

[0017] Preferably, the outer diameter of the outer decorative panel is smaller than the outer diameter of the end cap, and the circumferential surface of the outer decorative panel is an inclined surface.

[0018] In a second aspect, the present invention provides a quick-install carbon dioxide laser, including the aforementioned integral housing, wherein a laser tube is disposed within the integral housing.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an integral housing. The light-transmitting hole on the original end cap is enlarged into a lens mounting hole that allows for hand or tool insertion. An outer decorative panel is magnetically attached to the outside of the modified end cap. A new light-transmitting hole for the laser beam is set on the outer decorative panel. The outer decorative panel covers the enlarged lens mounting hole on the inner end cap, preventing external contaminants from directly entering the cylinder and limiting beam scattering and accidental contact. During installation, simply bring the outer decorative panel close to the end cap; the magnetism will automatically attract and fix it, and the positioning structure will radially position it, ensuring the light-transmitting hole is aligned with the laser beam. During disassembly, simply overcome the magnetic force to remove the outer decorative panel, and the lens can be inserted into the cylinder through the lens mounting hole for lens installation and maintenance, avoiding cumbersome steps such as tightening screws and removing the end cap. This provides a better user experience and higher maintenance efficiency.

[0020] 2. This utility model provides a quick-installation carbon dioxide laser. By adopting an improved integrated shell, it facilitates the installation and maintenance of the end lens of the laser tube, and the operation is simple, quick, and requires little work. Attached Figure Description

As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0026] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0027] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0028] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections.

[0029] Example 1 like Figure 2 , Figure 3 As shown, an integral housing includes a cylindrical body 1, an end cap 2, and an outer decorative panel 3. The cylindrical body 1 and the end cap 2 are fixed together by screws. At least one end of the end cap 2 has a lens mounting hole 21, and a positioning structure is provided on the side of the end cap 2 facing away from the cylindrical body 1. The outer decorative panel 3 is magnetically attached to the end face of the end cap 2. The outer decorative panel 3 has a light-transmitting hole 31 for a laser beam to pass through. The outer decorative panel 3 cooperates with the positioning structure to achieve radial positioning, ensuring the firmness and reliability of the connection of the outer decorative panel 3, especially in vibrating working environments, effectively preventing the outer decorative panel 3 from loosening. The diameter of the lens mounting hole 21 is larger than the diameter of the light-transmitting hole 31, allowing hands and tools to pass through the end cap 2 for lens installation.

[0030] In an optional embodiment, the outer decorative panel 3 is provided with a magnetic adsorption element 4 on the side facing the end cap 2, and the outer decorative panel 3 is magnetically adsorbed and fixed to the end face of the end cap 2 by the magnetic adsorption element 4. By precisely arranging the high-performance magnetic adsorption element 4 at the key stress points of the outer decorative panel 3, compared with making the entire outer decorative panel 3 with a material that can be magnetically adsorbed, a stronger and more concentrated magnetic attraction force can be obtained, and it is beneficial to reduce magnetic field interference and reduce the adsorption of ferromagnetic metal debris in the surrounding environment.

[0031] As one possible implementation, the magnetic adsorption component 4 is a permanent magnet, and the end cap 2 is made of a material that can be attracted by magnetic force, such as iron components, steel, etc.

[0032] As another possible implementation, the magnetic adsorption component 4 is a permanent magnet, and a magnetic conductive sheet or a second permanent magnet corresponding to the position of the permanent magnet is embedded or fixed on the end face of the end cap 2. The end cap 2 can be made of lightweight materials such as aluminum alloy or engineering plastics, which is beneficial for achieving lightweight structure, corrosion resistance, and low cost.

[0033] In an optional embodiment, the outer decorative panel 3 is provided with one or more handle grooves or lugs (not shown in the figure) on the side opposite to the end cover 2 to facilitate the operator to apply force, further improving the ease of disassembly and assembly.

[0034] In optional implementations, such as Figure 2 , Figure 3 As shown, the outer decorative panel 3 has an circumferential flange 32 on the outer periphery of the light-transmitting hole 31 on the side opposite to the end cap 2. By setting the circumferential flange 32 on the outer periphery of the light-transmitting hole 31, the length of the light-transmitting hole 31 is increased compared to the light-transmitting hole 31 flush with the outer decorative panel 3. This helps to improve the quality of the light beam and reduce background stray light, making it suitable for some application scenarios with extremely high signal-to-noise ratio requirements. The elongated light-transmitting hole 31 can form a physical barrier, increasing the difficulty for dust, splashes, or accidental contact to directly reach the core lens.

[0035] In an optional embodiment, the outer diameter of the outer decorative panel 3 is smaller than the outer diameter of the end cap 2, and the circumferential surface of the outer decorative panel 3 is beveled. This eliminates the sharp edges and corners of the outer decorative panel 3, avoiding the risk of operators being scratched during maintenance, and also making it less likely for the outer decorative panel 3 to shift due to accidental collisions.

[0036] The aforementioned integrated housing enlarges the light-transmitting hole 31 on the original end cap 2 into a lens mounting hole 21. This lens mounting hole 21 allows hands and tools to pass through the end cap 2 into the cylinder 1 for lens operation. An outer decorative panel 3 is magnetically attached to the outside of the modified end cap 2. A new light-transmitting hole 31 for the laser beam is set on the outer decorative panel 3. The outer decorative panel 3 covers the enlarged lens mounting hole 21 on the inner end cap 2, preventing external contaminants from directly entering the cylinder 1 and limiting beam scattering and accidental contact. During installation, simply bring the outer decorative panel 3 close to the end cap 2; the magnetism will automatically attract and fix it, and the positioning structure will radially position it, ensuring the light-transmitting hole 31 is aligned with the laser beam. During disassembly, simply overcome the magnetic force to remove the outer decorative panel 3, and the lens can be inserted into the cylinder 1 through the lens mounting hole 21 for lens installation and maintenance, avoiding cumbersome steps such as tightening screws and removing the end cap. This provides a better user experience and higher maintenance efficiency.

[0037] Example 2 Based on Example 1, such as Figure 2 As shown, in one or more embodiments, the positioning structure can be configured as a positioning protrusion, and the outer decorative plate 3 has a groove on the side facing the end cover 2 that engages with the positioning protrusion. Conversely, it can also be configured otherwise.

[0038] In an optional embodiment, the positioning protrusion is configured as a magnetic structure, and a magnetic adsorption element 4, such as a magnetic sheet or a permanent magnet, is provided in the groove on the mounting surface of the outer decorative panel 3 and magnetically attracted to the magnetic structure.

[0039] Example 3 Based on Embodiment 1, in one or more embodiments, the positioning structure can be configured as positioning posts, arranged at intervals along the circumference, and the outer decorative panel 3 is provided with positioning holes along the circumference, and the positioning posts are used to be inserted into the positioning holes.

[0040] In an optional embodiment, a magnetic adsorption component is embedded on the back of the end cap 2 of the outer decorative panel 3 to facilitate a tight fit between the outer decorative panel 3 and the end cap 2 and prevent dust from entering the assembly gap between the outer decorative panel 3 and the end cap 2.

[0041] Example 4 Based on any of the embodiments in Examples 1-3, this embodiment provides a quick-install carbon dioxide laser, including the above-mentioned integral housing, and a laser tube 5 is provided inside the integral housing.

[0042] By adopting an improved integrated housing, the installation and maintenance of the laser tube end lens can be facilitated, making the operation simple, quick, and requiring less work.

[0043] 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.
