[0002] With the rapid development of communication technology, the application of fiber optic switches is becoming more and more extensive. Fiber optic switches are a kind of high-speed network transmission relay equipment. Compared with ordinary switches, fiber optic switches use optical fiber cables as transmission media, with fast transmission speed and strong anti-interference ability. In practical applications, fiber optic switches generally need to be installed in fiber optic switch cabinets. Fiber optic switch cabinets are usually composed of frames, side panels and door panels. Heat dissipation holes are set on the door panels or side panels to increase the heat dissipation of the cabinet, and some electrical components and cables are placed inside. When fiber optic switches and other electrical components are damaged, they need to be removed from the cabinet for maintenance. For fiber optic switches or electrical components that can be repaired on site, there is often a lack of suitable maintenance sites; and the cabinet needs to be completely disassembled for maintenance and needs to be reinstalled after maintenance. The process is relatively cumbersome, and the large fiber optic switch is not easy to carry. Therefore, people need a fiber optic switch cabinet based on communication engineering to solve the above problems.

The present invention is scientific and reasonable, safe and convenient to use, and the sliding support frame assembly is convenient to provide people with an on-site maintenance site, and there is no need to disassemble the faulty instrument and move it to a maintenance point for maintenance, so as to avoid the instrument being too heavy and bulky to be moved and carried, and it is convenient to move the high placement rack to a lower position to facilitate people's operation. The sliding support frame assembly is also conducive to replacing the position of the fiber optic switch on the placement rack, without the need for carrying, which is convenient and quick.

[0004] When the above-mentioned device pulls the placement rack out of the cabinet, the entire placement rack and the optical fiber switch are supported only by the third slide rail.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Reference Figure 1 — Figure 5 As shown, the present invention provides: a fiber optic switch cabinet, comprising a cabinet body 1 and a bearing assembly 3, wherein two inner side walls of the cabinet body 1 are respectively provided with a bearing block 11 and a stop plate 12, a plurality of placement racks 2 are spaced apart between the two bearing blocks 11 in the vertical direction, the bearing assembly 3 is respectively arranged on both sides of the placement rack 2 and the bearing assembly 3 is inside the bearing block 11; the bearing assembly 3 comprises a side plate 31, a connecting rod 32, a supporting assembly 33 and a positioning assembly 34; the side plate 31 is fixed to one side of the placement rack 2 and slides with the bearing block 11 The connecting rod 32 is located inside the side panel 31 and the two ends of the connecting rod 32 are respectively connected to the supporting assembly 33 and the positioning assembly 34; the supporting assembly 33 is located inside the side panel 31 and away from the opening of the cabinet 1. When the side panel 31 slides out of the cabinet 1 in a direction away from the cabinet 1, the supporting assembly 33 is used to slide vertically inside the cabinet 1 and provide support for the positioning assembly 34; the positioning assembly 34 is located inside the side panel 31 and close to the opening of the cabinet 1, and the positioning assembly 34 is detachably fixedly connected to the inner wall of the side panel 31.

[0037] The two side walls inside the cabinet 1 are respectively provided with a load-bearing block 11 and a stop plate 12, wherein the stop plate 12 is closer to the opening of the cabinet 1 relative to the load-bearing block 11, and there is a certain interval between the stop plate 12 and the load-bearing block 11, thereby forming a first slide groove, the placement rack 2 has a plurality of them, and all the placement racks 2 are distributed inside the cabinet 1 at intervals along the vertical direction, and side panels 31 are respectively installed on both sides of the placement rack 2, and the side panels 31 are inserted into the load-bearing block 11 and are slidably connected to the load-bearing block 11, so that when the optical fiber switch inside the cabinet 1 is damaged, the corresponding placement rack 2 can be pulled toward the outside of the cabinet 1, so that the placement rack 2 and the optical fiber switch can be simultaneously pulled out of the cabinet 1, wherein the support components inside the side panels 31 When 33 moves to the opening of the cabinet 1, the support assembly 33 and the abutment plate 12 abut against each other, and at this time the support assembly 33 is in the first slide slot, so as to prevent the placement rack 2 and the optical fiber switch from being completely pulled out of the cabinet 1, which causes the staff to move the placement rack 2 and the optical fiber switch. When the support assembly 33 is in the first slide slot, the placement rack 2 can slide in the vertical direction, so as to move the placement rack 2 originally at different heights to a suitable height, so as to facilitate the staff to maintain and repair the optical fiber switch on the placement rack 2. At the same time, after the placement rack 2 moves to a suitable position, it can be moved by pushing the positioning assembly 34 inside the side panel 31 and the positioning assembly 34 can be moved. When the support assembly 33 is moved vertically downward, the support assembly 33 abuts against the side wall of the first slide slot, thereby limiting the support assembly 33 inside the first slide slot, so that the support assembly 33 can provide a supporting force to the positioning assembly 34 through the connecting rod 32, and at the same time, the positioning assembly 34 is detachably fixedly connected to the inner wall of the side panel 31, so that after the support assembly 33 is limited inside the first slide slot, the positioning assembly 34 can be fixed inside the side panel 31 at the same time, so that the support assembly 33, the positioning assembly 34 and the connecting rod 32 can be used to assist in supporting the entire placement rack 2. This prevents the placement rack 2 from sliding out of the cabinet 1 too much, which would reduce the supporting force of the cabinet 1 on the placement rack 2. At the same time, when the support assembly 33 and the positioning assembly 34 are both inside the side panel 31, the connection point between the connecting rod 32 and the positioning assembly 34 can be higher than the connection point between the connecting rod 32 and the support assembly 33. In this way, when the staff pushes the positioning assembly 34 close to the inside of the cabinet 1, the support assembly 33 can slide vertically downward smoothly under the push of the connecting rod 32. Under the action of the support assembly 33, the positioning assembly 34 and the connecting rod 32, the placement rack 2 can still stably support the fiber optic switch after being pulled out of the cabinet 1, so that the staff can smoothly inspect and maintain the fiber optic switch with problems.

[0038] Reference Figure 6 As shown: the support assembly 33 includes a support seat 331, a first abutment block 332, a push-down block 333 and a roller 334; the support seat 331 is located inside the side plate 31 and penetrates to the outside of the side plate 31; the first abutment block 332 has two and is symmetrically arranged inside the support seat 331; the push-down block 333 is slidably arranged inside the support seat 331 and is used to drive the two first abutment blocks 332 away from each other, the sliding direction of the push-down block 333 is perpendicular to the horizontal plane, and the push-down block 333 and the roller 334 abut against each other; the roller 334 is located inside the support seat 331 and is used to abut against the abutment plate 12 or the load-bearing block 11.

[0039] The support seat 331 is located inside the side panel 31 and close to the inside of the cabinet 1. The inside of the side panel 31 is provided with an opening that penetrates to the bottom end of the side panel 31, and the support seat 331 is connected to the connecting rod 32, so that when the staff pulls the placement rack 2 out from the inside of the cabinet 1, the support seat 331 can gradually approach the first slide groove between the abutment plate 12 and the load-bearing block 11 until the part of the support seat 331 that penetrates to the outside of the side panel 31 moves into the first slide groove, and then the placement rack 2 moves vertically as a whole until the placement rack 2 moves to a suitable height, so as to facilitate the staff to repair the optical fiber switch on the placement rack 2. After the whole is moved vertically to a suitable height, the staff starts to push the positioning assembly 34 close to the inside of the cabinet 1, and then the support seat 331 moves vertically downward under the push of the connecting rod 32. At this time, the support seat 331 slides vertically outward from the inside of the side panel 31. At this time, the roller 334 provided inside the support seat 331 begins to abut against the surface of the abutment plate 12 or the load-bearing block 11, and the support seat 331 continues to slide downward, thereby driving the roller 334 to rotate, and the push-down block 333 abuts against the roller 334, so that when the roller 334 rotates, the push-down block 333 can move vertically downward, thereby driving the two The first abutment block 332 moves away from each other until the first abutment block 332 slides out from the support seat 331 and abuts against the surface of the abutment plate 12 or the load-bearing block 11. At this time, the abutment surface of the first abutment block 332 can be provided with a structure such as a pattern to increase the friction force, so that when the first abutment block 332 abuts against the abutment plate 12 or the load-bearing block 11 respectively, the support seat 331 can be restricted in the first slide groove, so that the support seat 331 can provide a supporting force to the positioning assembly 34 through the connecting rod 32, and then provide auxiliary support for the placement rack 2 as a whole, thereby increasing the overall structural stability of the placement rack 2; when the staff has completed the maintenance of the fiber optic switch, it is necessary to To move the fiber optic switch back to its original position, first release the fixed connection between the positioning assembly 34 and the side panel 31, then pull the positioning assembly 34 to move it, so that the positioning assembly 34 is away from the cabinet 1, and then the positioning assembly 34 pulls the support seat 331 to slide vertically upward through the connecting rod 32. At this time, under the rotation of the roller 334, the push-down plate begins to move vertically upward, and the friction between the first abutment block 332 and the abutment plate 12 or the load-bearing block 11 is reduced, so that the support seat 331 can be smoothly displaced vertically upward until the support seat 331 returns to the inside of the side panel 31, and then the staff can move the placement rack 2 as a whole back to its initial position.

[0040] Reference Figure 6As shown: the support assembly 33 also includes a first gear 335; the push-down block 333 is provided with a rack that meshes with the first gear 335; the first gear 335 is located inside the support seat 331 and is on the same axis as the roller 334.

[0041] Racks can be set on both sides of the lower push plate, and two rollers 334 can also be set, one of which is used to abut against the abutment plate 12, and the other roller 334 is used to abut against the load-bearing block 11. At the same time, the two rollers 334 are coaxially provided with a first gear 335 that meshes with the rack. When the support seat 331 moves vertically, the roller can stably drive the lower push block 333 to move vertically through the first gear 335 and the rack, thereby driving the first abutment block 332 to abut firmly on the abutment plate 12 and the load-bearing block 11, or move away from the first abutment block 332. At the same time, in order to ensure that the roller 334 is tightly fitted with the abutment plate 12 and the load-bearing block 11, the roller 334 can be slidably set inside the support seat 331 and the sliding direction is parallel to the horizontal plane. A compression spring is provided between the racks on both sides of the lower push plate, so that the two gears can be driven The bars move away from each other, thereby pushing the roller 334 to slide toward the outside of the support seat 331, so that the roller 334 can fit tightly on the abutment plate 12 and the load-bearing block 11, and then when the support seat 331 slides vertically, the roller 334 can stably drive the push-down block 333 to move. At the same time, a C-shaped block can be further provided on the outside of the side plate 31, and the C-shaped block is composed of two mutually parallel first vertical plates and a second vertical plate for connecting the two first vertical plates, and the inner side wall of the first vertical plate abuts against the roller 334. When the support seat 331 is inside the side plate 31, under the restriction of the two first vertical plates, the roller 334 will not abut against the abutment plate 12 or the load-bearing block 11, so that when the placement rack 2 is moved vertically as a whole, the roller 334 is prevented from abutting against the abutment plate 12 or the load-bearing block 11 and affecting the overall vertical movement of the placement rack 2.

[0042] Reference Figure 6 and Figure 7 As shown: a first sliding block 336 corresponding to the first abutting block 332 is provided inside the support seat 331; the first sliding block 336 is slidably arranged inside the support seat 331; the first abutting block 332 is inserted into the first sliding block 336 and is slidably connected to the first sliding block 336; a first elastic component 337 connected to the first abutting block 332 is provided inside the first sliding block 336, and the first elastic component 337 is used to drive the first sliding block 336 and the first abutting block 332 to move away from each other.

[0043] The first sliding block 336 is slidably arranged inside the support seat 331 and abuts against the lower push block 333, so that when the lower push block 333 moves vertically downward, the two first sliding blocks 336 can move away from each other, thereby driving the first abutting block 332 to move toward the outside of the support seat 331 until the first abutting block 332 abuts against the abutment plate 12 or the load-bearing block 11, and then the lower push plate can continue to move downward. At this time, since the first abutting block 332 cannot continue to move, the first sliding block 336 begins to squeeze the first elastic component 337 inside and gradually approaches the first abutting block 332. At this time, under the action of the first elastic component 337, the first abutting block 332 can firmly abut against the abutment plate 12 or the load-bearing block 11, so that the support seat 331 can stably provide supporting force to the positioning component 34. The first elastic component 337 can adopt elastic elements such as compression springs or air springs, so as to stably drive the first abutting block 332 and the first sliding block 336 away from each other.

[0044] Reference Figure 8 As shown: the positioning assembly 34 includes a second sliding block 341, a second abutting block 342, a third abutting block 343 and a first screw rod 344; the second sliding block 341 is slidably arranged inside the side plate 31 and connected to the connecting rod 32; the second abutting block 342 has two and is relatively arranged inside the second sliding block 341; the third abutting block 343 is arranged inside the second sliding block 341 and abuts against the second abutting blocks 342 respectively; the first screw rod 344 passes through from the outside of the second sliding block 341 to the inside of the second sliding block 341 and is threadedly connected to the third abutting block 343; when the first screw rod 344 is rotated, the third abutting block 343 drives the two second abutting blocks 342 away from each other until the two second abutting blocks 342 abut against the inner wall of the side plate 31.

[0045] The second abutment block 342 has two and is relatively arranged inside the second sliding block 341, and the third abutment block 343 is inside the second interactive block and abuts against the second abutment block 342 respectively, so that when the third abutment block 343 moves, the two second abutment blocks 342 can move away from each other, and the movement direction of the second abutment block 342 is perpendicular to the horizontal plane, and then when the second abutment block 342 moves from the inside of the second sliding block 341 to the outside of the second sliding block 341, the second abutment block 342 can abut against the top or bottom end of the inner cavity of the side plate 31, and the abutment surface of the second abutment block 342 can be provided with a structure such as a pattern to increase friction, so that when the second abutment block 342 and the inner wall of the side plate 31 abut against each other, the friction between the second abutment block 342 and the inner wall of the side plate 31 can limit the second sliding block 341 to the inside of the side plate 31, thereby preventing the second sliding block 341 from moving and causing the support assembly 33 to move, thereby causing The support assembly 33 is unable to provide a stable supporting force for the placement rack 2 as a whole. When the placement rack 2 moves to a predetermined height, the staff starts to push the second sliding block 341 to move, so that the second sliding block 341 gradually approaches the inside of the cabinet 1, and under the action of the connecting rod 32, the support assembly 33 can slide vertically downward until the support assembly 33 is restricted inside the first sliding groove, so that the support assembly 33 can stably provide supporting force to the positioning assembly 34. Subsequently, the staff can rotate the first screw rod 344 on the outer side of the second sliding block 341 to drive the third abutment block 343 to move along the axial direction of the first screw rod 344, so as to drive the two second abutment blocks 342 away from each other, thereby fixing the second sliding block 341 inside the side panel 31, so that the support assembly 33, the positioning assembly 34 and the connecting rod 32 can stably provide a stable supporting force to the placement rack 2 as a whole, so that the staff can smoothly maintain and repair the optical fiber switch on the placement rack 2.

[0046] Reference Figure 8 As shown, a second elastic component 345 connected to the second abutting block 342 is disposed inside the second sliding block 341 ; the second elastic component 345 is used to drive the second abutting block 342 to approach the inside of the second sliding block 341 .

[0047] The second elastic component 345 can adopt an elastic element such as a tension spring, so that when the two second abutment blocks 342 are pushed away from each other by the third abutment block 343, the second elastic component 345 begins to be stretched, so that the second abutment block 342 can be continuously applied with a pulling force, so that when it is necessary to release the fixation of the second sliding block 341 inside the side panel 31, the first screw rod 344 can be rotated in the opposite direction first, so as to drive the third abutment block 343 away from the second abutment block 342, and then the second abutment block 342 begins to move toward the inside of the second sliding block 341 under the action of the second elastic component 345, and begins to move away from the inner wall of the side panel 31, so that the second sliding block 341 can slide inside the side panel 31, and then the second sliding block 341 can be driven away from the cabinet 1, and at this time, the supporting component 33 can be pulled back into the side panel 31 through the connecting rod 32, and then the placement rack 2 can be moved as a whole to its original height and pushed back into the cabinet 1.

[0048] Reference Figure 8 As shown: slide rails are respectively disposed on both sides of the third abutting block 343; and a slide groove cooperating with the slide rails is disposed on the inner wall of the second sliding block 341.

[0049] The third abutment block 343 is slidably connected to the inner wall of the second sliding block 341 through the sliding rail and the sliding groove, so that the third abutment block 343 can be guided and restricted, and when the first screw rod 344 is rotated, the third abutment block 343 can stably displace along the axial direction of the first screw rod 344. Under the restriction of the sliding rail and the sliding groove, the third abutment block 343 will not rotate.

[0051] The support frame 41 is slidably arranged inside the cabinet 1, and a slider 413 is provided at one end of the support rod 411 close to the inside of the cabinet 1, so that when the support frame 41 is pulled out to the outside of the cabinet 1, the slider 413 can abut against the abutment plate 12, and the slider 413 is slidably connected with the first slide groove, so as to guide the support frame 41 to slide vertically, so that after the placement rack 2 is pulled out and fixed from the inside of the cabinet 1, the staff can pull out the support frame 41 with the vacuum cleaner 42 from the inside of the cabinet 1, and then drive the support frame The rack 41 slides vertically downward, so that the support frame 41 can cover the placement rack 2, and the vacuum cleaner 42 is located between the two support rods 411 and is slidably connected to the slide rod 412, so that the dust on the optical fiber switch can be cleaned by the vacuum cleaner 42, thereby preventing the staff from inhaling dust when performing maintenance and repair on the optical fiber switch. After the dust on the optical fiber switch is cleaned by the vacuum cleaner 42, the support frame 41 can be moved back to the top of the cabinet 1, and then the staff can perform maintenance and repair on the optical fiber switch on the placement rack 2.

[0052] Reference Fig.10 As shown: the dust collection assembly 4 also includes a rope wheel 43, an auxiliary wheel 44 and a traction rope 45; the rope wheel 43 is located at the top of the inner cavity of the cabinet 1 and away from the opening of the cabinet 1; the auxiliary wheel 44 is located at the top of the inner cavity of the cabinet 1 and close to the opening of the cabinet 1; the traction rope 45 is sleeved on the rope wheel 43, and one end of the traction rope 45 passes through the auxiliary wheel 44 and is fixedly connected to the top of the support rod 411.

[0053] When it is necessary to clean the pulled-out optical fiber switch, the support frame 41 with the vacuum cleaner 42 needs to be pulled out from the inside of the cabinet 1. At this time, the support rod 411 in the support frame 41 is guided and restricted in the first slide groove by the slider 413 at the tail end, but the support frame 41 is in a suspended state as a whole. Therefore, a pulley 43 is set at the top of the inner cavity of the cabinet 1, and the pulley 43 can correspond to the support rod 411 one by one. An auxiliary wheel 44 can also be set at the top of the inner cavity of the cabinet 1, wherein the pulley 43 is away from the opening of the cabinet 1, and the auxiliary wheel 44 is close to the opening of the cabinet 1, so that The traction rope 45 needs to pass through the auxiliary wheel 44 before it can be fixedly connected to the top of the support rod 411, and the connection between the traction rope 45 and the support rod 411 is close to the opening of the cabinet 1, so that the support frame 41 can be smoothly vertically displaced by the traction of the support rod 411 by the traction rope 45. At the same time, a vertical plate can be set between the rope pulley 43 and the auxiliary wheel 44, and a damping ring for passing the traction rope 45 is provided on the vertical plate, thereby slowing down the release speed of the traction rope 45, so as to avoid damage caused by the support frame 41 with the vacuum cleaner 42 falling too fast.

[0054] Reference Fig. 9 As shown: a rubber pad 414 is provided at the bottom end of the support rod 411 .

[0055] By setting a rubber pad 414 at the bottom end of the support rod 411, it is possible to avoid collision between the support frame 41 and the side panel 31 to cause damage. At the same time, by changing the thickness of the rubber pad 414, the distance between the support frame 41 and the side panel 31 can be adjusted, thereby ensuring that there is enough space between the vacuum cleaner 42 and the optical fiber switch to work, and further avoiding collision between the vacuum cleaner 42 and the optical fiber switch.

[0056] Reference Fig.11 , Fig.12 As shown: it also includes a buffer component, which includes a cavity 501, the cavity 501 is arranged in one of the support rods 411, the cavity 501 is arranged along the length direction of the support rod 411, a rotating shaft 502 is arranged in the cavity 501, the rotating shaft 502 is parallel to the sliding rod 412, the rotating shaft 502 is rotatably connected to the inner wall of the cavity 501 at one end away from the vacuum cleaner 42, and the other end of the rotating shaft 502 extends to the outside of the cavity 501 and is fixedly connected to one end of the reciprocating screw 503, and the other end of the reciprocating screw 503 is connected to the cavity 501 away from the vacuum cleaner 42. 01 is rotatably connected to the outer wall of the support rod 411, a slide 504 is arranged on the reciprocating screw 503, the slide 504 is transmission-connected to the reciprocating screw 503, the lower end of the slide 504 is connected to the upper surface of the vacuum cleaner 42, a spring 505 is sleeved on the outer side of the rotating shaft 502, one end of the spring 505 is connected to the outer wall of the rotating shaft 502, and the other end of the spring 505 is connected to the inner wall of the cavity 501, a buffer plate 506 is arranged below the support rod 411 of the cavity 501, and a buffer rod 507 is arranged on the upper end of the buffer plate 506 The upper end of the buffer rod 507 passes through the bottom wall of the support rod 411 and extends into the cavity 501. A buffer spring 508 is sleeved on the outer wall of the buffer rod 507. One end of the buffer spring 508 is connected to the upper surface of the buffer plate 506. The other end of the buffer spring 508 is connected to the lower side wall of the support rod 411. Two slide plates 509 are arranged on the top wall of the cavity 501.

[0057] In order to further prevent the vacuum cleaner 42 from being damaged, a buffer assembly is further provided on the support frame 41. When the support frame 41 moves downward, the buffer plate 506 first contacts the side plate, and the buffer plate 506 drives the buffer rod 507 to slide into the cavity 501. The buffer spring 508 begins to compress, which can slow down the falling speed of the support frame 41 and prevent the vacuum cleaner 42 from falling too fast and colliding with the optical fiber switch, thereby improving safety. At the same time, the upward sliding of the buffer rod 507 can drive the two slide plates 509 to slide away from each other through the connecting rod 511. Elastic ropes 510 are provided between the slide plates 509. The elastic ropes 510 can be stretched during the sliding process of the slide plates 509, and the elastic force of the elastic ropes 510 can further The upward sliding speed of the buffer rod 507 is slowed down, thereby further buffering the fall of the support frame 41, ensuring that the support frame 41 moves downward smoothly. When the slides 509 move away from each other, one of the slides 509 drives the winding wheel 512 to rotate through the connecting rope 513, and the rotation of the winding wheel 512 drives the rotating shaft 502 to rotate, and the rotation of the rotating shaft 502 drives the reciprocating screw 503 to rotate, so that the slide 504 moves along the reciprocating screw 503, and the slide 504 drives the vacuum cleaner 42 to slide along the slide rod 412, so that the dust on the optical fiber switch is thoroughly cleaned. The vacuum cleaner 42 does not require manual operation during the cleaning process, and can automatically complete the cleaning of the surface of the optical fiber switch, which reduces the work intensity and further improves safety.
