Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0042] This utility model proposes an installation structure for use in laser processing equipment, used to install fire extinguishing gas cylinders and enabling quick assembly and disassembly of the cylinders. As understood, a fire extinguishing gas cylinder includes a cylinder body and a sealing valve located at the cylinder opening for sealing. During installation, the cylinder body needs to be fixed while simultaneously connecting the sealing valve to the venting connector assembly to facilitate timely venting when the fire extinguishing device is needed. The installation structure is described below with reference to an embodiment.

[0043] In the embodiments of this utility model, such as Figures 1 to 3As shown, the mounting structure includes a base 1, a vent connector assembly 2, and an opening / closing mechanism 3. The vent connector assembly 2 is located on the base 1 and is used to connect to the sealing valve 52 of the fire extinguishing gas cylinder 5. The opening / closing mechanism 3 is located on the base 1 and is spaced apart from the vent connector assembly 2. The opening / closing mechanism 3 includes a mounting base 31 located on the base 1 and a clamping member 32 hinged to the mounting base 31. The clamping member 32 can move closer to or further away from the mounting base 31 so that the opening / closing mechanism 3 has a locked state for clamping the fire extinguishing gas cylinder 5 and an open state for releasing the fire extinguishing gas cylinder 5.

[0044] The base 1 serves to support and install components such as the vent connector assembly 2 and the opening and closing mechanism 3. Optionally, the base 1 can be plate-shaped, block-shaped, strip-shaped, or other shaped structures. When applied to laser processing equipment, the mounting structure can be fixedly installed on the frame of the laser processing equipment via the base 1.

[0045] The venting connector assembly 2 is mounted on the base 1 and is used to connect to the sealing valve 52 of the fire extinguishing gas cylinder 5. Optionally, the venting connector assembly 2 is fixedly installed on the base 1, which can be achieved through threaded fixing, snap-fit ​​fixing, or welding fixing. Optionally, the sealing valve 52 can be a soda valve, which is installed to the venting connector assembly 2 through a threaded connection. When fire extinguishing is required, the sealing valve 52 of the fire extinguishing gas cylinder 5 opens, and the fire extinguishing gas (such as CO2) in the fire extinguishing gas cylinder 5 is released through the venting connector assembly 2. It can be understood that the fire extinguishing gas can be released directly from the venting connector assembly 2, or it can be transported to the target location for release through a pipeline connected to the venting connector assembly 2. The specific release method is not limited here.

[0046] The opening and closing mechanism 3 is located on the base 1 and spaced apart from the venting connector assembly 2. It can be understood that the opening and closing mechanism 3 serves to install and fix the body 51 of the fire extinguishing gas cylinder 5. This arrangement allows the sealing valve 52 at the cylinder opening of the fire extinguishing gas cylinder 5 to smoothly connect with the venting connector assembly 2. Specifically, the opening and closing mechanism 3 includes a mounting base 31 and a clamping member 32 hinged to the mounting base 31. The mounting base 31 is mounted on the base 1, and the clamping member 32 can rotate relative to the mounting base 31. When the clamping member 32 moves closer to the mounting base 31, a clamping space is formed between the clamping member 32 and the mounting base 31; when the clamping member 32 moves away from the mounting base 31, the clamping space is released. That is, the opening and closing mechanism 3 has a locked state and an open state.

[0047] When engaged, the clamping member 32 engages with the mounting base 31, creating a clamping space between the clamping member 32 and the mounting base 31 to clamp and fix the fire extinguishing gas cylinder 5.

[0048] When in the open position, the clamp 32 is located away from the mounting base 31, allowing the clamping space to expand and be released, so as to facilitate the removal or placement of the fire extinguishing gas cylinder 5.

[0049] In practical applications, when installing the fire extinguishing gas cylinder 5, first open the clamp 32 to the open position, place the fire extinguishing gas cylinder 5 on the mounting base 31 and screw it into the vent connector assembly 2, then move the clamp 32 to the locked position to limit and fix the fire extinguishing gas cylinder 5. When it is necessary to disassemble the fire extinguishing gas cylinder 5, simply open the clamp 32 to the open position and unscrew the fire extinguishing gas cylinder 5. In this way, the function of quickly disassembling and assembling the fire extinguishing gas cylinder 5 is realized, making the operation simpler and improving the efficiency of disassembly and assembly.

[0050] Optionally, the mounting base 31 is fixedly mounted on the base 1, which can be done by threaded fixing, snap-fit ​​fixing or welding fixing.

[0051] Optionally, the clamping member 32 can be hinged to the mounting base 31 via the first pivot 33. The engagement state between the clamping member 32 and the mounting base 31 can be achieved by the clamping member 32 itself being elastic, or by an elastic structure, a snap-fit ​​structure, or some other structure, etc., and the specific method is not limited here.

[0052] In summary, in the installation structure of this utility model, the base 1 is provided with a venting connector assembly 2 and an opening and closing mechanism 3. The venting connector assembly 2 is used to connect with the sealing valve 52 of the fire extinguishing gas cylinder 5. The opening and closing mechanism 3 includes a mounting base 31 and a clamping member 32 hinged to the mounting base 31. The clamping member 32 can move closer to or further away from the mounting base 31, so that the opening and closing mechanism 3 has a latching state for clamping the fire extinguishing gas cylinder 5 and an open state for releasing the fire extinguishing gas cylinder 5. This enables the quick disassembly and assembly of the fire extinguishing gas cylinder 5, simplifies the installation structure, and improves the disassembly and assembly efficiency.

[0053] To improve the installation reliability of fire extinguishing gas cylinder 5, such as Figure 1 and Figure 2 In one embodiment of this application, the opening and closing mechanism 3 further includes a locking member 34 connecting the clamping member 32 and the mounting base 31. The locking member 34 is used to lock the clamping member 32 and the mounting base 31 in the closed state and to unlock in the open state.

[0054] In this embodiment, the locking member 34 locks the clamping member 32 and the mounting base 31 in the engaged state, thereby ensuring the clamping and fixing force of the clamping member 32 and the mounting base 31 on the fire extinguishing gas cylinder 5. Correspondingly, when it is necessary to disassemble the fire extinguishing gas cylinder 5, the locking member 34 can be unlocked, allowing the clamping member 32 to move relative to the mounting base 31 to the open state, so as to facilitate the removal of the fire extinguishing gas cylinder 5.

[0055] Optionally, the specific structure of the locking element 34 can be determined according to the actual situation, such as a snap-locking structure, a pry-locking structure, or some other locking structure.

[0056] As an example, such as Figure 1 and Figure 2 The locking member 34 includes a first locking member 341, a second locking member 342, and an elastic member 343. The first locking member 341 is located at the end of the clamping member 32 away from the hinge end. The second locking member 342 is rotatably connected to the end of the mounting base 31 away from the hinge end for locking with the first locking member 341. The elastic member 343 is connected between the second locking member 342 and the mounting base 31 for providing elastic force to keep the second locking member 342 and the first locking member 341 locked together.

[0057] This embodiment illustrates the structure of the locking member 34. A first locking member 341 is disposed on the clamping member 32, and a second locking member 342 is rotatably disposed on the mounting base 31. Optionally, the second locking member 342 is mounted to the mounting base 31 via a second rotating shaft 344. The second locking member 342 can rotate along the second rotating shaft 344 to engage or disengage the first locking member 341. An elastic member 343 connects the mounting base 31 and the second locking member 342. When the clamping member 32 moves to the engaged state, the second locking member 342 engages with the first locking member 341. Simultaneously, the elastic member 343 maintains the elastic force providing engagement between the second locking member 342 and the first locking member 341, resulting in a better engagement effect between the second locking member 342 and the first locking member 341, and a stronger locking effect between the clamping member 32 and the mounting base 31, thereby improving the installation reliability of the fire extinguishing gas cylinder 5. When it is necessary to disassemble the fire extinguishing gas cylinder 5, the staff can directly press the second fastener 342, so that the second fastener 342 rotates relative to the mounting base 31 to disengage from the first fastener 341, thereby releasing the clamping member 32 and the mounting base 31, so that the clamping member 32 can move to the open state, making it easy to remove the fire extinguishing gas cylinder 5.

[0058] Optionally, the elastic element 343 is located on the side of the second latching element 342 away from the first latching element 341, and the elastic element 343 is a spring.

[0059] Furthermore, such as Figure 1 and Figure 2 The locking fastener 34 also includes a retaining ring 345 movably disposed on the mounting base 31. The retaining ring 345 is used to engage the first retaining fastener 341 when in the engaged state and to disengage from the first retaining fastener 341 when in the unengaged state.

[0060] In this embodiment, a retaining ring 345 is provided on the mounting base 31. This retaining ring 345 can engage the first retaining member 341 when it is locked to the second retaining member 342. This design prevents accidental contact between the second retaining member 342 and the first retaining member 341 by personnel or other components, thus further improving the locking reliability of the locking member 34. Correspondingly, when it is necessary to unlock the locking member 34, the operator only needs to rotate the retaining ring 345 to disengage from the first retaining member 341 and then press the second retaining member 342 to unlock, allowing the clamping member 32 to move to the open state.

[0061] Optionally, the retaining ring 345 can also be rotatably connected to the mounting base 31 via the second pivot 344. This design eliminates the need for an additional pivot structure, simplifies the structural layout, and saves material costs.

[0062] In one embodiment of this application, as Figure 1 and Figure 2 The mounting base 31 is provided with a first clamping groove 311, and the clamping member 32 is provided with a second clamping groove 321. When in the snap-fit ​​state, the second clamping groove 321 and the first clamping groove 311 are connected to form a clamping space for clamping the fire extinguishing gas cylinder 5.

[0063] Optionally, the first clamping groove 311 is a concave arc-shaped groove; the second clamping groove 321 is a concave arc-shaped groove. With this configuration, when the clamping member 32 is engaged with the mounting base 31, the clamping space formed by the engagement of the second clamping groove 321 and the first clamping groove 311 can better fit the shape of the body 51 of the fire extinguishing gas cylinder 5, and the clamping force on the fire extinguishing gas cylinder 5 is stronger.

[0064] In one embodiment, the mounting base 31 is provided with a plurality of spaced-apart first support ribs 312 within the first clamping groove 311. This design can enhance the support strength of the mounting base 31 on the one hand, and reduce weight and save materials on the other. Optionally, the plurality of first support ribs 312 are distributed at intervals along the length direction of the fire extinguishing gas cylinder 5, so that the force on the fire extinguishing gas cylinder 5 is more balanced.

[0065] In one embodiment, the clamping member 32 is provided with a plurality of spaced-apart second support ribs 322 within the second clamping groove 321. This design can enhance the structural strength of the clamping member 32 on the one hand, and reduce weight and save materials on the other. Optionally, the plurality of second support ribs 322 are distributed at intervals along the length direction of the fire extinguishing gas cylinder 5, so that the force on the fire extinguishing gas cylinder 5 is more balanced.

[0066] In one embodiment of this application, as Figure 1 and Figure 3The venting connector assembly 2 includes a support 21 and a venting connector 22. The support 21 is fixedly disposed at one end of the base 1 and spaced apart from the opening and closing mechanism 3. The venting connector 22 is disposed on the support 21 for threaded connection with the sealing valve 52 of the fire extinguishing gas cylinder 5.

[0067] In this embodiment, the support 21 serves to support the installation of the vent connector 22, ensuring that the height of the vent connector 22 aligns with the sealing valve 52 at the mouth of the fire extinguishing gas cylinder 5. It is understood that the fire extinguishing gas can be released directly from the vent connector 22, or it can be transported to the target location for release via a pipeline connected to the vent connector 22.

[0068] Optionally, the support 21 and the base 1 can be fixed by screws, welding, or clips.

[0069] Furthermore, a sealing ring 6 is provided between the sealing valve 52 and the venting connector 22 to ensure a sealed connection between the sealing valve 52 and the venting connector 22.

[0070] In one embodiment of this application, as Figure 1 The installation structure also includes a photoelectric sensor 4 located on the vent connector assembly 2 to detect whether the fire extinguishing gas cylinder 5 is installed.

[0071] This utility model also proposes a fire extinguishing device, which includes a fire extinguishing gas cylinder 5 and an installation structure. The specific structure of the installation structure is as described in the above embodiments. Since this fire extinguishing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The fire extinguishing gas cylinder 5 is installed between the clamping member 32 and the mounting base 31, and the sealing valve 52 of the fire extinguishing gas cylinder 5 is connected to the venting connector assembly 2.

[0072] This utility model also proposes a laser processing device 1000, such as... Figure 4 and Figure 5 The laser processing equipment 1000 includes a frame 200, a cover door 300, a laser processing module 400, and a fire extinguishing device 100. The specific structure of the fire extinguishing device 100 is as described in the above embodiments. Since the laser processing equipment 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0073] The cover door 300 is rotatably connected to the frame 200. The frame 200 and the cover door 300 enclose a processing space 201. The cover door 300 can be rotated to open or close the processing space 201. The laser processing module 400 is movably installed in the processing space 201. The fire extinguishing device 100 is installed in the frame 200. The venting connector assembly 2 is connected to the processing space 201.

[0074] In this embodiment, the frame 200 serves as a base support and can be a frame structure, chassis structure, or other structure. The frame 200 can be a cuboid or a cube. The frame 200 and the cover door 300 enclose a processing space 201 for laser processing. The cover door 300 is rotatably mounted on the frame 200 and can open or close the processing space 201. The laser processing module 400 is disposed within the processing space 201 and can output laser light to perform laser processing on the workpiece. The cover door 300 has at least a partially translucent window, which allows the user to observe the laser processing module 400 processing the workpiece inside the frame 200. The window can also filter the high-power laser light output and reflected by the laser processing module 400, providing isolation and protection for the user.

[0075] In some embodiments, the frame 200 is further provided with a track device, which includes an X-axis track 510 and a Y-axis track 520. The X-axis track 510 is movably disposed on the Y-axis track 520, and the laser processing module 400 is movably disposed on the X-axis track 510. Thus, the laser processing module 400 moves within the processing space 201 via the track device. The workpiece material is placed at the bottom of the processing space 201. During processing, the laser processing module 400 moves above the workpiece and outputs laser light, thereby realizing laser processing of the workpiece.

[0076] The fire extinguishing device 100 is installed inside the frame 200. The outlet of the gas release connector assembly 2 of the fire extinguishing device 100 is connected to the processing space 201. It can be used to release fire extinguishing gas in the processing space 201 to extinguish the fire when a fire occurs in the processing space 201. After the fire is extinguished, the fire extinguishing device 100 stops releasing fire extinguishing gas to prevent the fire extinguishing gas from leaking out.

[0077] like Figure 4 and Figure 5 In one embodiment of this application, the frame 200 is further provided with a storage room 202 separated from the processing space 201. The fire extinguishing device 100 is installed in the storage room 202. The fire extinguishing device 100 is provided with an air pipe 101. One end of the air pipe 101 is connected to the air outlet of the vent connector 2 assembly, and the other end passes through the storage room 202 and communicates with the processing space 201.

[0078] This design allows the fire extinguishing device 100 to be installed outside the processing space 201, structurally isolating it from the processing space 201 and preventing damage to the fire extinguishing device 100's structure during laser processing. Optionally, the fire extinguishing device 100 can be installed on the outer side, bottom, or top of the processing space 201. The fire extinguishing device 100 is equipped with a gas pipe 101. One end of the gas pipe 101 is connected to the outlet of the gas release connector 2 assembly, and the other end passes through the storage chamber 202 and communicates with the processing space 201. Understandably, when a fire occurs in the processing space 201, the fire extinguishing gas in the fire extinguishing device 100 can be delivered to the processing space 201 through the gas pipe 101 to extinguish the fire; after the fire is extinguished, the fire extinguishing device 100 stops releasing fire extinguishing gas into the gas pipe 101 to prevent leakage. This design ensures the structural reliability of the fire extinguishing device 100 during normal laser processing, and also ensures that the fire extinguishing device 100 can extinguish the fire inside the processing space 201 in a timely manner in the event of a fire.
