[0038] Figure 3 is a partial structure sectional view of the optical coupler provided in this embodiment during the disassembly of the window sheet frame 200; Figure 4 is a partial structure sectional view of the optical coupler provided in this embodiment after the disassembly of the window sheet frame 200 is completed. Please continue to refer to Figure 1 , and combine Figure 3 and Figure 4 , the window sheet frame 200 is provided with sheet grooves 211 and clamping grooves 212 arranged at intervals along its in-out direction, the sheet grooves 211 are used for installing the window sheet 500; the fixing assembly 300 includes a clamping seat 310, a first elastic member 320 and a second elastic member 330, wherein the clamping seat 310 is movably arranged inside the shell 100, the side of the clamping seat 310 facing the driving hole 120 is provided with a driving inclined surface 311, from the driving hole 120 to the clamping seat 310, the driving inclined surface 311 extends obliquely towards the window sheet frame 200, the clamping seat 310 has a locking position clamped into the clamping groove 212 and an unlocking position out of the clamping groove 212; the first elastic member 320 is configured to make the clamping seat 310 always have a movement tendency of clamping into the clamping groove 212, and the second elastic member 330 is configured to make the window sheet frame 200 pop out through the mounting hole 110 when the clamping seat 310 exits the clamping groove 212.

[0039] The optical coupler is provided as above, so that in the normal installation state of the window sheet 500, the clamping seat 310 is in the locking position clamped into the clamping groove 212 of the window sheet frame 200, so as to fix the window sheet frame 200 to the shell 100. When it is needed to take out the window sheet 500 in the window sheet frame 200, an acting force can be applied to the driving inclined surface 311 of the clamping seat 310 through the driving hole 120, so as to drive the clamping seat 310 to exit the clamping groove 212, make the clamping seat 310 switch from the locking position to the unlocking position, and release the locking state of the clamping seat 310 to the window sheet frame 200. At this time, under the action of the second elastic member 330, the window sheet frame 200 pops out through the mounting hole 110, as shown in Figure 3 , the operator can directly take down the window sheet frame 200 and the window sheet 500 arranged thereon, so as to achieve the disassembly purpose of the window sheet 500, as shown in Figure 4 .

[0040] When it is needed to re-mount the window sheet frame 200 to the shell 100, the window sheet frame 200 can be inserted through the mounting hole 110 and pushed, in the process, the window sheet frame 200 slides on the driving slope 311 of the clamping seat 310, and the first elastic member 320 is first driven to be compressed, when the window sheet frame 200 gradually moves to the position where the clamping groove 212 is opposite to the clamping seat 310, the clamping seat 310 will be clamped into the clamping groove 212 under the elastic restoring force of the first elastic member 320, so as to realize the fixation of the window sheet frame 200, at the same time, the second elastic member 330 is gradually compressed to accumulate the elastic potential energy for the next ejection operation of the window sheet frame 200, thus, the mounting of the window sheet frame 200 is completed.

[0041] Therefore, the optical coupler is provided as above, so that when the dismounting operation of the window sheet frame 200 is performed, the automatic ejection of the window sheet frame 200 can be realized only by applying the driving force to the clamping seat 310 through the driving hole 120, and when the mounting operation of the window sheet frame 200 is performed, the automatic clamping of the clamping seat 310 and the clamping groove 212 can be realized only by pushing the window sheet frame 200 into the mounting hole 110, the dismounting process and the mounting process are simple, the operation is convenient, and the efficiency is high.

[0042] Please continue to refer to Figure 1 , Figure 3 and Figure 4 In the embodiment, the fixing assembly 300 can further include a fixing seat 340, specifically, the fixing seat 340 is fixedly arranged in the shell 100, and the fixing seat 340 is provided with a containing groove for containing the clamping seat 310 and a sliding groove for moving the window sheet frame 200 in and out.

[0043] The above arrangement of the fixing seat 340 provides a mounting basis for the clamping seat 310, on the one hand, the modular arrangement of the fixing assembly 300 can be realized, so that the fixing assembly 300 can be integrally mounted to the shell 100, on the other hand, the machining difficulty of the shell 100 is also reduced.

[0044] Please continue to refer to Figure 1 In the embodiment, the fixing seat 340 can include a first mounting section 341, a connecting section 342 and a second mounting section 343, the first mounting section 341, the connecting section 342 and the second mounting section 343 are connected in sequence to form a U-shaped structure, and the first mounting section 341 and the second mounting section 343 are arranged along the Y direction, wherein the containing groove is arranged in the connecting section 342, and the sliding groove is formed between the first mounting section 341 and the second mounting section 343; the first mounting section 341 and the second mounting section 343 are both provided with connecting screw holes 344, and the shell 100 is provided with connecting light holes 130 opposite to the connecting screw holes 344.

[0045] By setting the fixing seat 340 to the above form, on the one hand, the mounting opening is formed between the first mounting section 341 and the second mounting section 343, facilitating the installation of the card seat 310, and on the other hand, by opening the connecting screw holes 344 in the first mounting section 341 and the second mounting section 343, and opening the connecting light holes 130 corresponding to the connecting screw holes 344 in the shell 100, when the fixing seat 340 is installed, the connecting screw can be used to pass through the connecting light holes 130 opened in the shell 100 and be screwed in the connecting screw holes 344 opened in the first mounting section 341 and the second mounting section 343, so as to realize the assembly connection of the fixing seat 340 and the shell 100. This connection mode not only ensures the stability of the installation of the fixing seat 340, but also facilitates the disassembly of the fixing seat 340, so as to realize the modular maintenance of the fixing assembly 300.

[0046] Please continue to refer to Figure 1 In the embodiment, the first mounting section 341 and the second mounting section 343 are both provided with two connecting screw holes 344 arranged at intervals along the X direction, and correspondingly, the shell 100 is provided with four connecting light holes 130, and the positions of the four connecting light holes 130 correspond to the positions of the four connecting screw holes 344 one by one.

[0047] Please continue to refer to Figure 1 、 Figure 3 and Figure 4 In the embodiment, the fixing assembly 300 can also include a rotating shaft 350. Specifically, the rotating shaft 350 extends along the Y direction, and the card seat 310 is rotatably installed on the fixing seat 340 through the rotating shaft 350, wherein the card seat 310 rotates to switch between the locked position and the unlocked position.

[0048] When the driving slope 311 of the card seat 310 is subjected to a pushing force through the driving hole 120, the card seat 310 will swing upward along the axis of the rotating shaft 350 to exit the clamping groove 212 of the window sheet holder 200, thereby releasing the limiting action on the window sheet holder 200, so that the window sheet holder 200 can be ejected through the mounting hole 110 under the action of the second elastic member 330. At this time, under the action of the first elastic member 320, the card seat 310 always has a downward rotating tendency.

[0049] When the window sheet holder 200 is reloaded into the shell 100, the window sheet holder 200 will first slide on the driving slope 311 of the card seat 310 and compress the first elastic member 320 to accumulate elastic potential energy as it moves inwardly in the mounting hole 110; when the clamping groove 212 of the window sheet holder 200 moves to the position of the card seat 310, the card seat 310 will be clamped into the clamping groove 212 under the elastic restoring force of the first elastic member 320, thereby achieving the limiting and fixing of the window sheet holder 200.

[0050] The card seat 310 is switched between the locked position and the unlocked position by rotating, which occupies less space and has a simple structure and is easy to arrange.

[0051] Specifically, in the embodiment, the card seat 310 is sleeved on the rotating shaft 350, one end of the rotating shaft 350 is pivotally connected to the first mounting section 341, and the other end of the rotating shaft 350 is pivotally connected to the second mounting section 343.

[0052] It can be understood that in other embodiments, the card seat 310 can also be arranged to slide along the Z direction to switch between the unlocked position and the locked position.

[0053] Please continue to refer to Figure 1 , Figure 3 and Figure 4 In the embodiment, the fixed assembly 300 can further include a limiting pin 360 extending along the X direction, specifically, the limiting pin 360 is fixedly installed on the fixed seat 340, and the limiting pin 360 is arranged on the two sides of the card seat 310 away from the driving hole 120; the side of the card seat 310 away from the driving hole 120 is provided with a strip-shaped hole 312 extending along the Z direction, wherein the limiting pin 360 is inserted into the strip-shaped hole 312, and the limiting pin 360 can abut against both ends of the strip-shaped hole 312 to limit the rotating stroke of the card seat 310.

[0054] Please continue to refer to Figure 3 and Figure 4 During the upward rotation of the card seat 310 to exit from the card slot 212, when the lower end of the strip-shaped hole 312 abuts against the limiting pin 360 after the rotation of the card seat 310, the freedom of upward rotation of the card seat 310 is limited, at this time, the card seat 310 is rotated to the maximum angle position; during the downward rotation of the card seat 310 to be clamped into the card slot 212, when the upper end of the strip-shaped hole 312 abuts against the limiting pin 360 after the rotation of the card seat 310, the freedom of downward rotation of the card seat 310 is limited, at this time, the card seat 310 is rotated to the maximum angle position.

[0055] The above-mentioned limiting pin 360 and strip-shaped hole 312, on the one hand, can limit the rotating stroke of the card seat 310, which can ensure the smooth switching of the card seat 310 between the unlocked position and the locked position, and can also avoid the card seat 310 from being rotated upward at too large an angle to hit the fixed seat 340 and avoid the card seat 310 from being rotated downward at too large an angle to cause large wear to the window sheet holder 200, which plays a protective role for the fixed seat 340 and the window sheet holder 200; on the other hand, the cooperation of the limiting pin 360 and the strip-shaped hole 312 can also play a guiding role during the rotation of the card seat 310.

[0056] Please continue to refer to Figure 3 and Figure 4In the embodiment, the card seat 310 is provided with a mounting groove 313 on the side away from the window frame 200. Specifically, the first elastic member 320 comprises a helical spring extending along the Z direction. The first elastic member 320 is accommodated in the mounting groove 313. One end of the first elastic member 320 abuts against the bottom wall of the mounting groove 313. The other end of the first elastic member 320 abuts against the fixed seat 340.

[0057] By setting the first elastic member 320 as a helical spring, the structure is simple, and the first elastic member 320 is easy to arrange. By providing the card seat 310 with the mounting groove 313 for accommodating the first elastic member 320, on the one hand, the mounting groove 313 can guide the deformation of the first elastic member 320, preventing the first elastic member 320 from being bent. On the other hand, the first elastic member 320 can be detachably mounted between the card seat 310 and the fixed seat 340, so that the first elastic member 320 is easy to disassemble and maintain.

[0058] It should be noted that in other embodiments, the first elastic member 320 can also be set as a torsion spring. At this time, the torsion spring can be sleeved on the rotating shaft 350. One torsion arm of the torsion spring is fixed relative to the card seat 310. The other torsion arm of the torsion spring is fixed relative to the fixed seat 340. This setting can also accumulate elastic potential energy when the card seat 310 is turned upward, and make the card seat 310 clamped into the card slot 212 by the elastic restoring force after the window frame 200 enters the mounting hole 110.

[0059] Please continue to refer to Figure 1 In the embodiment, the window frame 200 can comprise a bearing section 210 and a handheld section 220. Specifically, the bearing section 210 is used for being inserted into the mounting hole 110. The card slot 211 and the card slot 212 are both arranged on the bearing section 210. In the assembly position of the window frame 200, the handheld section 220 covers the mounting hole 110 and the driving hole 120. The handheld section 220 is provided with a clearance hole 221 opposite to the driving hole 120.

[0060] When it is needed to take out the window frame 200 from the mounting hole 110, a tool can be used to sequentially pass through the clearance hole 221 and the driving hole 120 to apply a force to the driving slope 311 of the card seat 310. This setting makes it possible to smoothly apply a force to the card seat 310 through the driving hole 120, while the mounting hole 110 and the driving hole 120 can be covered by the handheld section 220 in the assembly position of the window frame 200, avoiding the pollution caused by the exposure of the mounting hole 110.

[0061] Figure 5 The structure of the optical coupler provided in the embodiment in the moment when the film taking needle 400 contacts the driving slope 311 is shown in a sectional view. As shown in Figure 5As shown, in the assembled position of the window sheet rack 200, the handheld section 220 is coplanar with the outer surface of the housing 100.

[0062] With this arrangement, there is no protruding or recessed structure on the surface where the handheld section 220 is located, ensuring the neat appearance of the optical coupler.

[0063] Please continue to refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, the second elastic member 330 can include an elastic pin. Specifically, the second elastic member 330 is fixedly arranged on one side of the fixed seat 340 facing the driving hole 120. The housing 100 is also provided with a through hole 140 for the second elastic member 330 to pass through. The second elastic member 330 passes through and abuts against the handheld section 220.

[0064] When the window sheet rack 200 is in the assembled position, the second elastic member 330 is compressed by the handheld section 220. At this time, the second elastic member 330 accumulates elastic potential energy. When the clamping groove 212 is released from the clamping restriction of the clamping seat 310, the elastic potential energy accumulated by the second elastic member 330 is released, and the elastic restoring force is applied to the handheld section 220, thereby realizing the ejection action of the window sheet rack 200.

[0065] The second elastic member 330 is arranged in this way, which can accumulate a large amount of elastic potential energy when the window sheet rack 200 is in the assembled position, thereby ensuring the reliability of the ejection of the window sheet rack 200.

[0066] Specifically, in this embodiment, the number of second elastic members 330 can be two, and the two second elastic members 330 are arranged along the Y direction. This arrangement allows both ends of the handheld section 220 to be simultaneously acted upon by the second elastic members 330, ensuring the balance of the force acting on the handheld section 220, thereby reducing the jamming during the ejection of the window sheet rack 200.

[0067] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the optical coupler can further include a sheet taking needle 400, wherein the sheet taking needle 400 can pass through the driving hole 120 and act on the clamping seat 310.

[0068] The arrangement of the sheet taking needle 400 allows the operator to smoothly apply a force to the driving inclined surface 311 of the clamping seat 310, thereby reliably switching the clamping seat 310 from the locked position to the unlocked position.

[0069] Please continue to refer to Figure 1Specifically, the taking-out needle 400 can include a needle-shaped section 410 and a ring-shaped section 420. With the needle-shaped section 410, the acting force can be smoothly applied to the card seat 310; and the ring-shaped section 420 is arranged to facilitate the operator to take the taking-out needle 400.

[0070] Please continue to refer to Figure 1 In the embodiment, the optical coupler can further include a cover 600, wherein the cover 600 is arranged at the open position of the shell 100.

[0071] The process of taking out the window sheet 500 from the optical coupler is as follows.

[0072] Please continue to refer to Figure 5 In the assembled state of the window sheet holder 200, the taking-out needle 400 is sequentially inserted through the accommodation hole 221 of the hand-held section 220 and the driving hole 120 of the shell 100, and abuts against the driving inclined surface 311 of the card seat 310.

[0073] Figure 6 The optical coupler provided in the embodiment is in a structure sectional view after the window sheet holder 200 is ejected through the mounting hole 110. As shown in Figure 6 , the taking-out needle 400 is used to apply the acting force to the driving inclined surface 311 of the card seat 310, at this time, the taking-out needle 400 will slide on the driving inclined surface 311, thereby driving the card seat 310 to rotate clockwise around the rotating shaft 350, so that the card seat 310 is withdrawn from the card groove 212 to release the locking of the card seat 310 to the window sheet holder 200; subsequently, under the elastic restoring force of the second elastic member 330, the window sheet holder 200 is ejected through the mounting hole 110. In this process, the first elastic member 320 is compressed under the action of the taking-out needle 400.

[0074] Figure 7 The optical coupler provided in the embodiment is in a structure sectional view after the window sheet holder 200 is completely taken out through the mounting hole 110.
