[0029] Please refer to Figures 1 to 5 The utility model proposes a kind of switching structure 100, applied to therapeutic instrument, switching structure 100 includes closed switch 1, closed switch 1 includes shell 11, coupling piece 12 and baffle 13, shell 11 is equipped with light hole 114, coupling piece 12 is connected with baffle 13 transmission;When coupling piece 12 is coupled with light guide body 3, baffle 13 is away from light hole 114, when coupling piece 12 is not coupled with light guide body 3, baffle 13 covers light hole 114.

[0030] It can be understood that therapeutic instrument includes laser and light guide body, laser can emit laser, light guide body can be connected with the output end of laser, for transmitting laser.

[0031] In the embodiment, the adapter structure 100 is installed at the output end of the laser, the closing switch 1 includes a shell 11, a coupling member 12 and a baffle 13, the shell 11 is provided with a light exit hole 114 for laser emission, and the baffle 13 can be driven by the coupling member 12 to approach or move away from the light exit hole 114, thereby closing or opening the light exit hole 114. The coupling member 12 is coupled with the light guide body 3, when the light guide body 3 is connected with the laser, the coupling member 12 is coupled with the light guide body 3, and drives the baffle 13 to move away from the light exit hole 114, so that the light exit hole 114 is opened, and the laser output from the laser can enter the light guide body 3 from the light exit hole 114, and normal laser transmission is performed. When the light guide body 3 is detached from the laser, the coupling member 12 is no longer coupled with the light guide body 3, and the coupling member 12 drives the baffle 13 to approach the light exit hole 114, so that the light exit hole 114 is covered by the baffle 13, thereby avoiding that the light exit hole loses the shielding after the light guide body 3 is detached from the laser, and external dust or impurities enter the laser from the light exit hole and accumulate on the optical path lens, thereby affecting the quality of the laser output. The setting of the adapter structure 100 makes it unnecessary to manually install or detach the shielding object from the output end of the laser during the process of detaching and installing the light guide body 3, thereby improving the convenience of operation.

[0032] It can be understood that the closing switch 1 is a modular structure, and the closing switch 1 can be integrally installed on or detached from the output end of the laser. Alternatively, the shell 11 of the closing switch 1 can be integrally arranged with the shell of the laser, which is not limited herein. Alternatively, the light guide body 3 in the embodiment can be an optical fiber or a light guide arm.

[0033] In actual implementation, the coupling member 12 can be coupled with the light guide body 3 through a mechanical structure, such as an elastic pressing structure, and when the light guide body 3 is connected with the coupling member 12, the coupling member 12 is deformed or moved to be coupled with the light guide body 3. The coupling member 12 and the light guide body 3 can also be coupled through an electric / magnetic signal, such as that the coupling member 12 is provided with a Hall sensor, and the light guide body 3 is provided with a magnet, and when the light guide body 3 is connected with the coupling member 12, the Hall sensor can detect the magnetic field strength when the magnet approaches, so as to determine that the light guide body 3 and the coupling member 12 are coupled.

[0034] The baffle 13 can be driven through a mechanical structure or a motor, and in the process of coupling the coupling member 12 and the light guide body 3 through the mechanical structure, the deformation or movement of the coupling member 12 can provide driving force for the movement of the baffle 13, and drive the baffle 13 to move away from the light exit hole 114, so that the light exit hole 114 is opened. After the coupling member 12 and the light guide body 3 are coupled through the cooperation of the Hall sensor and the magnet, the Hall sensor can send a driving signal to the motor, so as to drive the baffle 13 to move away from the light exit hole 114, so that the light exit hole 114 is opened.

[0035] In an embodiment of the present application, as shown in Figures 1 to 3 The coupling member 12 includes a pressing portion 121 and a transmission portion 122, the pressing portion 121 is movably connected to the shell 11, the transmission portion 122 is in transmission connection with the pressing portion 121, and the baffle 13 is connected to one end of the transmission portion 122.

[0036] In the embodiment, the coupling member 12 is coupled with the light guide body 3 through a mechanical structure and drives the baffle 13 to rotate. When the light guide body 3 is connected to the laser, the light guide body 3 will press the pressing portion 121, the pressing portion 121 drives the transmission portion 122 to drive the baffle 13 to move away from the light emitting hole 114, so as to open the light emitting hole 114. Optionally, the pressing portion 121 can be connected to the shell 11 through rotation or sliding, which is not limited here.

[0037] In actual implementation, the connection between the light guide body 3 and the laser is end face to end face insertion, the plane where the light emitting hole 114 is located is usually parallel to the end face of the light guide body 3, the insertion direction of the light guide body 3 and the laser is perpendicular to the plane where the light emitting hole 114 is located, and the covering plane of the baffle 13 is arranged in parallel with the plane where the light emitting hole 114 is located. The direction perpendicular to the plane where the light emitting hole 114 is located is defined as a first direction, the direction parallel to the plane where the light emitting hole 114 is located is defined as a second direction, the pressing direction of the pressing portion 121 in the embodiment can be the first direction, so as to facilitate the abutting cooperation of the light guide body 3, and the moving direction of the baffle 13 can be the second direction, so as to facilitate the covering plane of the baffle 13 to completely cover or open the light emitting hole 114. The transmission cooperation between the transmission portion 122 and the pressing portion 121 can change the driving direction transmitted from the pressing portion 121 to the baffle 13, so that the pressing portion 121 can drive the baffle 13 which has a different moving direction from the pressing portion 121.

[0038] In an embodiment of the present application, as shown in Figures 2 to 5 The pressing portion 121 includes a sliding block 1211 and a sliding groove 1212 arranged on the sliding block 1211, the sliding block 1211 is in sliding connection with the shell 11, at least part of the transmission portion 122 is limited in the sliding groove 1212, and the sliding block 1211 is used to drive the transmission portion 122 to move along the sliding groove 1212.

[0039] In the embodiment, the sliding block 1211 is used to abut against the light guide body 3, and the sliding block 1211 is in sliding fit with the shell 11, such as sliding fit through the sliding hole 1111 or sliding rail. When the light guide body 3 is installed on the laser, the light guide body 3 abuts against the sliding block 1211, and the sliding block 1211 slides relative to the shell 11. The sliding block 1211 is provided with a sliding groove 1212 in sliding fit with the transmission part 122, and when the sliding block 1211 slides relative to the shell 11, the transmission part 122 slides relative to the sliding block 1212 in the sliding groove 1212, thereby driving the baffle 13 to move. The sliding groove 1212 guides the movement of the transmission part 122, and is used to guide the transmission part 122 to drive the baffle 13 to move in a preset direction.

[0040] In actual implementation, the shell 11 includes an upper shell 111 and a lower shell 112, which are detachably connected to enclose a cavity 113 and a light outlet hole 114 in communication with the cavity 113. The upper shell 111 is further provided with a sliding hole 1111 in communication with the cavity 113. The transmission part 122 and the baffle 13 are located in the cavity 113, and the baffle 13 can move between the cavity 113 and the light outlet hole 114. The sliding block 1211 slides through the sliding hole 1111, and when the sliding block 1211 is abutted by the light guide body 3, the sliding block 1211 moves along the sliding hole 1111 and drives the transmission part 122 to drive the baffle 13 to move from the cavity 113 to the light outlet hole 114 to cover the light outlet hole 114. The sliding hole 1111 is provided to enable the sliding block 1211 to move in a preset direction, thereby avoiding deviation of the sliding block 1211 to cause the transmission part 122 to fail to normally drive the baffle 13 to open or close the light outlet hole 114.

[0041] Alternatively, the sliding groove 1212 can also be provided on the transmission part 122, and at least part of the sliding block 1211 is located in the sliding groove 1212, so that the sliding block 1211 can also drive the transmission part 122 to move.

[0042] In an embodiment of the utility model, the extension direction of the sliding groove 1212 is arranged at an angle with the moving direction of the sliding block 1211. That is, the extension direction of the sliding groove 1212 has at least a component perpendicular to the moving direction of the sliding block 1211, and the moving track of the transmission part 122 located in the sliding groove 1212 also has the same component as the sliding groove 1212, so that the pressing part 121 can drive the baffle 13 to move in a direction different from the moving direction of the pressing part 121 through the transmission part 122.

[0043] In actual implementation, the moving direction of the baffle 13 can be vertically arranged perpendicularly to the moving direction of the sliding block 1211. The sliding groove 1212 is arranged obliquely relative to the sliding block 1211 and the baffle 13, the extending direction of the sliding groove 1212 is arranged at an angle to the moving direction of the sliding block 1211 and the moving direction of the baffle 13, and is not arranged perpendicularly to the moving direction of the sliding block 1211 and the moving direction of the baffle 13.

[0044] In an embodiment of the present application, as shown in Figures 3 to 5 The transmission part 122 comprises a rotating section 1222 and a driving section 1221. The rotating section 1222 is rotationally connected with the shell 11. The driving section 1221 is connected with the two ends of the rotating section 1222, and the driving section 1221 is movably limited in the sliding groove 1212.

[0045] In the embodiment, the rotating section 1222 is rotationally connected with the shell 11 through shaft hole cooperation or hinge, etc. The rotating plane of the rotating section 1222 can be parallel to the plane where the light emitting hole 114 is located.

[0046] When the pressing part 121 moves relative to the shell 11, the driving section 1221 will move in the sliding groove 1212 relative to the shell 11, and drive the rotating section 1222 to rotate relative to the shell 11. The rotating section 1222 drives the baffle 13 to move away from or close to the light emitting hole 114, so as to open or close the light emitting hole 114. The rotation cooperation between the rotating section 1222 and the shell 11 can limit the moving direction of the transmission part 122, thereby ensuring that the transmission part 122 can drive the baffle 13 to move away from or close to the light emitting hole 114 in a preset direction.

[0047] It can be understood that the moving track of the driving section 1221 and the baffle 13 located at the two ends of the rotating part is actually an arc, and the center of the arc is located on the rotating part. The sliding block 1211 is provided with a guide plate 1211d, the guide plate 1211d is arranged in an arc shape, and the curvature of the guide plate 1211d is equivalent to the curvature of the moving track of the driving section 1221. The sliding groove 1212 is arranged on the guide plate 1211d, so that the driving section 1221 can be prevented from being separated from the sliding groove 1212 when moving along the sliding groove 1212.

[0048] Optionally, the distance between the baffle 13 and the rotation center of the rotating section 1222 can be set to be farther than the distance between the driving section 1221 and the rotation center of the rotating section 1222. In this way, when the driving section 1221 and the baffle 13 rotate by the same angle, the baffle 13 moves a farther distance, and the baffle 13 is more easily opened or covers the light emitting hole 114. The driving section 1221, the rotating section 1222 and the baffle 13 can be integrally arranged.

[0049] In an embodiment of the present application, as shown in Figure 2 , Figure 4 and Figure 5As shown, the coupling member 12 further comprises a reset elastic member 123, one end of the reset elastic member 123 is connected with the shell 11, and the other end of the reset elastic member 123 is connected with the sliding block 1211, the reset elastic member 123 is used to drive the sliding block 1211 to drive the baffle 13 to cover the light outlet hole 114.

[0050] It can be understood that when the light guide body 3 is connected with the laser, the sliding block 1211 is pressed to the lowest position by the light guide member, and remains in this position under the continuous pressing of the light guide member, and the transmission part 122 also remains in the position of moving the baffle 13 out of the light outlet hole 114 completely, so that the light outlet remains in the open state.

[0051] In the embodiment, the sliding block 1211 is also connected with the shell 11 through the reset elastic member 123, when the sliding block 1211 is moved by the pressing of the light guide member, the reset elastic member 123 is also moved, the reset elastic member 123 is deformed, accumulates elastic potential energy, and remains in the deformed state under the continuous pressing of the light guide member. When the light guide member is detached from the laser, the sliding block 1211 and the reset elastic member 123 lose the limit of the light guide member, the reset elastic member 123 automatically rebounds, drives the sliding block 1211 to reset, and drives the transmission part 122 to drive the baffle 13 to reset, that is, the baffle 13 is close to the light outlet and covers the light outlet.

[0052] In actual implementation, the reset elastic member 123 is in a compressed or stretched state when the sliding block 1211 is pressed by the light guide member according to different setting positions. When the reset elastic member 123 is located on the side of the sliding block 1211 away from the light guide member, the reset elastic member 123 is compressed as the sliding block 1211 is pressed by the light guide member; when the reset elastic member 123 is located between the sliding block 1211 and the light guide member, the reset elastic member 123 is stretched as the sliding block 1211 is pressed by the light guide member.

[0053] Optionally, the reset elastic member 123 can be a spring or a spring sheet. Optionally, the sliding block 1211 is further provided with a positioning column 1211c, and the reset elastic member 123 is sleeved on the positioning column 1211c, so as to improve the stability of the reset elastic member 123 during deformation and resetting.

[0054] In actual implementation, the slider 1211 can include a mounting plate 1211a, slide columns 1211b connected to two sides of the mounting plate 1211a, a positioning column 1211c, and a guide plate 1211d connected to the mounting plate 1211a. The guide plate 1211d is provided with a sliding groove 1212, the slide columns 1211b are arranged in the slide holes 1111 of the shell 11 and are used to abut against the light guide body 3, the mounting plate 1211a and the positioning column 1211c are located in the cavity 113 of the shell 11, the slide holes 1111 pass through the upper shell 111, and the side of the mounting plate 1211a close to the slide columns 1211b can also abut against and be limited by the upper wall of the cavity 113; the reset elastic member 123 is sleeved on the positioning column 1211c and is limited between the mounting plate 1211a and the lower shell 112, the lower shell 112 is provided with a positioning hole for the positioning column 1211c to pass through, so as to avoid and guide the movement of the positioning column 1211c.

[0055] In an embodiment of the present application, as shown in Figure 2 , Figure 4 and Figure 5 , the closure switch 1 further includes a locking member 14, the locking member 14 is slidingly connected to the shell 11, and the locking member 14 is used to limit the movement of the slider 1211. Wherein, Figure 5 is a sectional view of the locking member 14 locking the slider 1211 when the light emitting hole 114 is in an open state.

[0056] In the embodiment, the locking member 14 locks the position of the slider 1211 through the limiting cooperation with the slider 1211, thereby locking the position of the baffle 13, so that the light emitting hole 114 remains in an open or closed state. When the laser does not install the light guide body 3 and needs to open the light emitting hole 114 for debugging, the locking member 14 can lock the slider 1211 to keep the light emitting hole 114 in an open state.

[0057] It can be understood that the locking of the slider 1211 by the locking member 14 can avoid the reset elastic member 123 from automatically driving the slider 1211 to reset, so that the baffle 13 covers the light emitting hole 114 and the light emitting hole 114 is closed.

[0058] In actual implementation, the locking member 14 can be slidingly connected with the shell 11 through a slide rail or a slide groove, and the sliding direction of the locking member 14 is arranged at an angle with the moving direction of the sliding block 1211. The locking member 14 comprises a sliding part 141 and a locking part 142. The upper shell 111 is provided with a sliding groove 1112 for the sliding part 141 to slide in, and the sliding part 141 is located in the sliding groove 1112, so as to manually move the locking member 14 by a user. The locking part 142 can be locked with the position of the sliding block 1211 through clamping cooperation or abutting cooperation. For example, the sliding block 1211 is provided with a first clamping groove and a second clamping groove. When the light emitting hole 114 is in the open state, the sliding part 141 is slid towards the sliding block 1211, and the locking part 142 can extend into the first clamping groove, so as to limit the upward movement of the sliding block 1211 and drive the baffle 13 to cover the light emitting hole 114 through the transmission member. When the light emitting hole 114 is in the closed state, the sliding part 141 is slid towards the sliding block 1211, and the locking part 142 can extend into the second clamping groove, so as to limit the downward movement of the sliding block 1211 and drive the baffle 13 to open the light emitting hole 114 through the transmission member. Alternatively, the sliding groove 1112 is partially arranged through the upper shell 111, so as to extend the locking part 142 into the cavity 113 to lock the sliding block 1211.

[0059] In the embodiment, the sliding block 1211 comprises a mounting plate 1211a, slide columns 1211b and positioning columns 1211c connected to both sides of the mounting plate 1211a, and a guide plate 1211d connected to the mounting plate 1211a. The locking part 142 of the locking member 14 can abut against the mounting plate 1211a, so as to lock the position of the sliding block 1211. When the light emitting hole 114 is in the open state, the sliding part 141 of the sliding block 1211 is slid towards the sliding block 1211, and the locking part 142 can abut against the upper surface of the mounting plate 1211a to limit the upward movement of the sliding block 1211 and drive the baffle 13 to cover the light emitting hole 114 through the transmission member. The locking part 142 can abut against the lower surface of the mounting plate 1211a to limit the downward movement of the sliding block 1211 and drive the baffle 13 to open the light emitting hole 114 through the transmission member.

[0060] In an embodiment of the utility model, as shown in Figure 2 and Figure 3 , the number of baffles 13 and transmission parts 122 is multiple, and each baffle 13 is connected to a transmission part 122. As shown in Figure 2 and Figure 3 , the number of baffles 13 and transmission parts 122 is two, and each transmission part 122 corresponds to a baffle. At the same time, the number of slide grooves 1212 is also two. The sliding block 1211 is driven to move by two transmission parts 122, so that the covering area of each sliding block 1211 can be half of the area of the light emitting hole 114. The distance required for the sliding block 1211 to open or close the light emitting hole 114 is reduced, which is conducive to reducing the overall structure of the closing switch 1.

[0061] In actual implementation, each transmission part 122 comprises a driving section 1221 and a rotating section 1222, each baffle 13 is connected to an end of the rotating section 1222 away from the driving section 1221, the two groups of transmission parts 122 and baffles 13 are symmetrically arranged, rotating shafts of the rotating sections 1222 of the two groups of transmission parts 122 are coaxially arranged, the two groups of transmission parts 122 are crosswise arranged, the slider 1211 is provided with a sliding groove 1212 corresponding to each transmission part 122, and the two sliding grooves 1212 are symmetrically arranged. When the slider 1211 is pressed downward by the light guide and moves downward, the slider 1211 drives the driving sections 1221 of the two groups of transmission parts 122 to move in opposite directions, thereby driving the two baffles 13 to move away from each other to open the light outlet hole 114. When the slider 1211 moves upward to reset, the slider 1211 drives the driving sections 1221 of the two groups of transmission parts 122 to move towards each other, thereby driving the two baffles 13 to move close to each other to close the light outlet hole 114.
