[0033] Refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which is a schematic diagram of the connection between the quick-release sealing structure and the base provided by an embodiment of the present utility model. Figure 2 which is a schematic diagram of the connection between the quick-release sealing structure and the spectacle frame and the base plate provided by an embodiment of the present utility model. Figure 3A cross-sectional view of a quick-release sealing structure provided by an embodiment of the present invention connected to a frame and a bottom plate. The quick-release sealing structure provided by an embodiment of the present invention comprises a main body 100 and a stopper 200; a support platform 110 is provided at the end of the main body 100, the support platform 110 comprises a notch 120, a support surface 111 and a mating surface 130, the support surface 111 is used to abut against the base, the mating surface 130 is located on the side of the support surface 111 away from the base, one end of the stopper 200 is used to connect to the base, the other end of the stopper 200 has a predetermined distance from the base, and the stopper 200 is configured to switch between the notch 120 and the mating surface 130 when the support platform 110 rotates along a first direction, so as to press the support platform 110 against the base, or release the support platform 110.

[0034] Specifically, when it is necessary to install the quick-release sealing structure on the substrate, the support surface 111 of the support platform 110 is abutted against the substrate, and the limiting member 200 is placed at the notch 120. By controlling the main body 100 to rotate relative to the substrate in the first direction, the limiting member 200 can be switched from the notch 120 to the side of the mating surface 130 away from the support surface 111, and abut against the mating surface 130, so that the support platform 110 can be pressed onto the substrate, and the quick-release sealing structure and the substrate can be conveniently installed. When it is necessary to disassemble the quick-release sealing structure, it is only necessary to rotate the main body 100 in the opposite direction to separate the limiting member 200 from the mating surface 130, so that the limiting member 200 is switched from the mating surface 130 to the notch 120, thereby releasing the constraint on the support platform 110, so that the quick-release sealing structure can be separated from the substrate, and the disassembly is completed. That is, in the present application, the cooperation between the stopper 200 and the support platform 110 realizes the convenient installation and removal of the quick-release sealing structure, thereby improving the convenience of the installation and removal of the quick-release sealing structure. Preferably, the first direction is parallel to the horizontal plane.

[0035] It should be noted that in this embodiment, the quick-release sealing structure in the present application is used in laser processing equipment, and the substrate can be a bottom plate 410 or a lens frame 420, wherein a laser channel 169 is provided on the main body 100 for transmitting laser light, and the light spot can be observed by disassembling the quick-release sealing structure. In other embodiments, the substrate can be other brackets.

[0036] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, the support platform 110 includes a guide slope 132 , one end of the guide slope 132 is continuous with the mating surface 130 , and the other end of the guide slope 132 is inclined toward a side close to the support surface 111 and extends to a side of the notch 120 .

[0037] Specifically, in the first direction, the distance between the guiding inclined surface 132 and the supporting surface 111 gradually increases. Thus, when the main body portion 100 rotates relative to the base along the first direction, the side of the guiding inclined surface 132 close to the notch can first extend into the gap between the limiting member 200 and the base, thereby playing a guiding role and facilitating the movement of the limiting member 200 along the guiding inclined surface 132 to the mating surface 130 to abut against the mating surface 130.

[0038] Refer to Figure 1 , Figure 2 and Figure 3 , in one embodiment, the limiting member 200 includes an elastic piece 210 and a fastening block 220. One end of the elastic piece 210 is connected to the base through the fastening block 220, and the other end of the elastic piece 210 has a predetermined distance from the base. The elastic piece 210 is configured to deform when the main body portion 100 moves relative to the base along the first direction to switch to the mating surface 130, so as to press against the mating surface 130.

[0039] Specifically, after the elastic piece 210 abuts against the guiding inclined surface 132, during the process that the main body portion 100 continues to rotate relative to the base along the first direction, since the distance between the guiding inclined surface 132 and the supporting surface 111 gradually increases, the thrust force of the guiding inclined surface 132 on the elastic piece 210 gradually increases, so that the deformation degree of the elastic piece 210 becomes larger and larger, and further the pressing force applied to the supporting surface 111 is greater, improving the stability of the support platform 110 installed on the base. Preferably, the elastic piece 210 is made of spring steel.

[0040] It should be noted that, in the initial state, the distance between the end of the elastic piece 210 and the base is greater than the distance between the side of the guiding inclined surface 132 close to the notch 120 and the supporting surface 111.

[0041] Refer to Figure 1 , Figure 2 and Figure 3 , in one embodiment, a limiting post 150 is provided on the mating surface 130. The limiting post 150 is configured to abut against the limiting member 200 when the limiting member 200 rotates relative to the mating surface 130 to a preset position, so as to limit the main body portion 100 from continuing to rotate relative to the base along the first direction. That is, when the limiting member 200 abuts against the limiting post 150, it indicates that the main body portion 100 and the base have been installed in place.

[0042] Further, a threaded hole is provided on the support platform 110, and the limiting post 150 is threadedly connected to the support platform 110. Preferably, the limiting post 150 is a set screw.

[0043] Refer to Figure 1 , Figure 2 and Figure 3, in one embodiment, the number of the limiting members 200 is at least two, the number of the notches 120 and the mating surfaces 130 corresponds to the number of the limiting members 200, and each mating surface 130 is disposed between two adjacent corresponding notches 120.

[0044] Specifically, each notch 120 is used to avoid the corresponding limiting member 200, so that each limiting member 200 can cooperate with the corresponding mating surface 130 to realize the limitation of the support platform 110, that is, the support platform 110 in the present application is pressed against the base by at least two limiting members 200, improving the stability of the installation of the main body portion 100 on the base. Among them, in this embodiment, the number of the notches 120 is two.

[0045] Refer to Figure 1 , Figure 2 and Figure 3 , in one embodiment, the support platform 110 further includes a protruding portion 140, the protruding portion 140 protrudes outward from the support surface 111, and the base includes a positioning hole 430 adapted to the protruding portion 140, and the protruding portion 140 is configured to cooperate with the hole wall of the positioning hole 430 to slide along a first direction.

[0046] Specifically, the protruding portion 140 is circular, and the protruding portion 140 is inserted into the positioning hole 430 to realize the pre-positioning of the main body portion 100. The protruding portion 140 is slidably connected to the hole wall of the positioning hole 430 along the first direction, thereby guiding the main body portion 100, so that the main body portion 100 and the base can stably rotate along the first direction to realize the cooperation between the limiting member 200 and the mating surface 130.

[0047] Refer to Figure 1 , Figure 2 and Figure 3 , in one embodiment, the main body portion 100 further includes a handle 300, one end of the handle 300 is connected to the support platform 110, the other end of the handle 300 extends away from the support platform 110, and the handle 300 operably drives the support platform 110 to rotate along the first direction.

[0048] Specifically, when the support platform 110 is rotated by operating the handle 300, since the distance between the force application point and the axis of the support platform 110 is increased, that is, the force arm is increased, the torque is increased without changing the applied force, so it is more labor-saving, improving the convenience of installation and disassembly of the quick-release sealing structure.

[0049] Further, the handle 300 is threadedly connected to the threaded hole on the support platform 110, so as to facilitate the replacement of the handle 300. Preferably, the handle 300 is a screw rod.

[0050] Refer to Figure 1 , Figure 2 and Figure 3, in one embodiment, support platforms 110 are provided at both ends of the main body portion 100. The two support platforms 110 are respectively crimped to the corresponding base body through at least one limiting member 200, so that the two ends of the main body portion 100 can be separated from and installed on the base body relatively conveniently by rotation, improving the convenience of installation and disassembly of the quick-release sealing structure. Among them, the two support platforms 110 are respectively crimped to the mirror frame 420 and the bottom plate 410 through the limiting members 200.

[0051] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in one embodiment, the main body portion 100 further includes a connecting member 160, an elastic member 170 and a supporting member 180. The supporting member 180 is connected to the support platform 110. A through hole 162 is further provided on the side wall of the connecting member 160. A groove 181 is provided on the supporting member 180. The elastic member 170 passes through the through hole, and a part of the elastic member 170 extends into the groove 181 and is in plug-in fit with the groove 181.

[0052] Specifically, when the supporting member 180 extends into the installation hole 161, the elastic member 170 is in a compressed state, and the end of the elastic member 170 abuts against the side wall of the supporting member 180, so as not to limit the relative movement of the docking member and the supporting member 180 in the axial direction of the main body portion 100. When the elastic member 170 is opposite to the groove 181, the elastic member 170 resumes deformation, and the end of the elastic member 170 extends into the groove 181, so as to limit the relative movement of the connecting member 160 and the supporting member 180 in the axial direction, making the connecting member 160 and the supporting member 180 stably connected. When disassembling the supporting member 180 and the connecting member 160, applying a force that makes them move away from each other can cause the elastic member 170 to deform, so that the end of the elastic member 170 disengages from the groove 181, so that the supporting member 180 and the connecting member 160 can move axially to be separated. That is, in this application, through the cooperation of the elastic member 170 and the groove 181, the convenient installation and disassembly between the connecting member 160 and the supporting member 180 are realized. Preferably, the number of the elastic members 170 is multiple, and the elastic members 170 are arranged at intervals in the circumferential direction.

[0053] It should be noted that the detachably arranged connection between the supporting member 180 and the connecting member 160 can reduce the influence of the support platform 110 on the main body portion 100 when rotating relative to the base body for installation or disassembly, prevent the main body portion 100 from twisting, and improve the reliability of the quick-release sealing structure.

[0054] Furthermore, the groove 181 is arranged around the circumference of the supporting member 180, so that when installing the supporting member 180 and the connecting member 160, it is not necessary to align the elastic member 170 and the groove 181 axially, improving the installation efficiency.

[0055] Refer to Figure 1 、 Figure 3 and Figure 4 , in one embodiment, the number of the support members 180 is two. Mounting holes 161 and through holes 162 are provided at both ends of the connecting member 160. The two support members 180 are respectively inserted into the two mounting holes 161. The number of the elastic members 170 is at least two. At least two elastic members 170 respectively pass through the through holes 162 at both ends of the connecting member 160 and extend into the corresponding grooves 181, and are inserted and matched with the corresponding grooves 181. That is, both ends of the connecting member 160 can be conveniently connected and disassembled with the support members 180 through the elastic members 170 respectively, improving the convenience of installation and disassembly of the quick-release sealing structure.

[0056] Refer to Figure 1 、 Figure 3 and Figure 4 , in one embodiment, the elastic member 170 is a spring plunger. The thread of the spring plunger is threadedly connected to the hole wall of the through hole 162. The ball head of the spring plunger is inserted and matched with the groove 181, and under the action of the spring in the thread, the ball head can extend into or out of the groove 181.

[0057] Further, a chamfer for transition is provided on the groove side wall of the groove 181, so as to facilitate the smooth sliding of the ball head into or out of the groove.

[0058] Refer to Figure 1 、 Figure 3 and Figure 4 , in one embodiment, the main body portion 100 further includes a mating block 171. The mating block 171 is connected to the portion of the elastic member 170 extending outside the through hole 162, and the mating block 171 abuts against the connecting member 160, thereby reducing the shaking of the elastic member 170 relative to the connecting member 160 and improving the stability of the connection between the elastic member 170 and the connecting member 160.

[0059] Further, the outer wall of the connecting member 160 includes an abutting surface 167. The mating block 171 abuts against the abutting surface 167 and fits with the abutting surface 167, thereby increasing the contact area between the mating block 171 and the connecting member 160 and improving the stability of the connection between the elastic member 170 and the connecting member 160. Preferably, the mating block 171 is a nut and the abutting surface 167 is a flat surface.

[0060] Refer to Figure 1 、 Figure 2 and Figure 3, in one embodiment, the connecting member 160 includes a telescopic cover 163, a fixing ring 164 and a hose clamp 165. The end of the telescopic cover 163 is sleeved on the fixing ring 164, and the hose clamp 165 is sleeved on the telescopic cover 163 to fix the telescopic cover 163 on the fixing ring 164. The mounting hole 161 and the through hole 162 are both provided on the fixing ring 164, and the elastic member 170 is connected to the fixing ring 164.

[0061] Specifically, the number of the fixing rings 164 and the hose clamps 165 is two. Both ends of the telescopic cover 163 are respectively sleeved on the fixing rings 164 and fixed on the fixing rings 164 through the corresponding hose clamps 165. The telescopic cover 163 can be telescoped, so as to play a buffering role when disassembling the quick-release sealing structure and avoid being damaged. Among them, when it is necessary to observe the light spot, the main body 100 can be disassembled, or the support member 180 can be separated from the connecting member 160.

[0062] Refer to Figure 1 、 Figure 3 and Figure 4 , in one embodiment, the support member 180 is provided with a first boss 183. The first boss 183 is located on one side of the groove 181 close to the mating surface 130. The quick-release sealing structure further includes a gasket 168. The gasket 168 is sleeved on the support member 180 and abuts against both the first boss 183 and the fixing ring 164, so that it can be clamped by the first boss 183 and the fixing ring 164 to seal the gap between the support member 180 and the connecting member 160 and prevent dust from entering.

[0063] Refer to Figures 1 - 5 , Figure 5 is a schematic diagram of the support platform in the quick-release sealing structure provided by an embodiment of the present invention. In one embodiment, the support member 180 includes an adapter tube 182. The first boss 183 and the groove 181 are provided on the adapter tube 182. The adapter tube 182 is further provided with a second boss 184. The second boss 184 is connected to the support platform 110 through a fastening block 220 such as a screw.

[0064] Furthermore, the support member 180 further includes a bottom sealing tube 190. The bottom sealing tube 190 is connected to the support platform 110 and inserted into the adapter tube 182 to improve the sealing performance of the laser channel 169 on the main body 100.

[0065] Refer to Figures 1 - 5 , an embodiment of the present invention further provides a laser processing device, which includes the above-mentioned quick-release sealing structure, and further includes a bottom plate 410 and a mirror frame 420. The bottom plate 410 or the mirror frame 420 is configured as a base body, and the support platform 110 is press-connected to the bottom plate 410 or the mirror frame 420 through a limiting member 200.

[0066] Specifically, the support platform 110 at both ends of the main body 100 is respectively pressed against the bottom plate 410 and the frame 420 through the stopper 200. In the present application, the distance between at least a portion of the mating surface 130 and the support surface 111 gradually increases in the first direction. When the quick-release sealing structure needs to be installed on the substrate, the support surface 111 of the support platform 110 is abutted against the substrate, and the end of the stopper 200 is located on the side of the mating surface 130 away from the support surface 111. By controlling the main body 100 to move relative to the substrate along the first direction, the stopper 200 and the mating surface 130 can move relative to each other, so that the stopper 200 can abut against the mating surface 130, and then the support platform 110 can be pressed against the substrate, so as to realize the convenient installation of the quick-release sealing structure and the substrate. When the quick-release sealing structure needs to be disassembled, the main body 100 only needs to be rotated in the opposite direction to separate the stopper 200 from the mating surface 130, thereby releasing the constraint on the support platform 110 and allowing the quick-release sealing structure to be separated from the base. That is, in the present application, the quick-release sealing structure is conveniently installed and disassembled through the cooperation between the stopper 200 and the support platform 110, thereby improving the convenience of installing and disassembling the quick-release sealing structure.
