Description

Technical Field

[0001] This utility model relates to the field of fiber optic distribution frame technology, and in particular to a pull-out fiber optic distribution frame. Background Technology

[0002] Fiber optic distribution frames are fiber optic cabling equipment specifically designed for fiber optic communication equipment rooms. They have functions such as fiber optic cable fixing and protection, fiber optic cable termination, cable adjustment, and protection of fiber optic cores and pigtails.

[0003] Most existing pull-out fiber optic patch panels only have a pull-out function. Due to the lack of an effective limiting mechanism, the patch panel often cannot remain fixed after being moved to a suitable position, which makes it easy for it to shift due to slight external forces during use, thus causing inconvenience. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pull-out fiber optic distribution frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pull-out fiber optic distribution frame includes a housing. A hinged flap is connected to one side of the housing. C-shaped plates are fixedly connected to the inner walls of both sides of the housing. Slide plates are provided inside each of the two C-shaped plates. A movable component is provided between the C-shaped plates and the slide plates to allow the slide plates to slide within the C-shaped plates. The fiber optic distribution frame body is rotatably connected to the two slide plates near the bottom via a bearing. A limit block is fixedly connected to one side of one of the slide plates. A second inclined surface is provided on one side of the limit block. A clearance groove is provided on one side of the housing. A slide frame is slidably connected to one side of one of the C-shaped plates, and the slide frame passes through the clearance groove. U-shaped frames that are adapted to the limit block are fixedly connected to both ends of the slide frame through the C-shaped plates. A first inclined surface is provided on one side of the U-shaped frame. Two first springs are sleeved on the outer side of the slide frame, and the two ends of the first springs are fixed to the C-shaped plate and the U-shaped frame, respectively.

[0007] As a further embodiment of this utility model, the moving component includes multiple rollers, and grooves are provided at the top and bottom of the two C-shaped plates. The multiple rollers are rotatably connected to the multiple grooves through bearings. Slides are provided at the top and bottom of the two slide plates, so that the slide plates can move within the C-shaped plates through the cooperation of the slides and grooves.

[0008] As a further embodiment of this utility model, the top of the fiber optic distribution frame body is fixedly connected to two fixing blocks, and a second spring is fixedly connected to the opposite side of each of the two fixing blocks. One end of the second spring is fixedly connected to an L-shaped block, and the top of each of the two sliding plates is fixedly connected to a sleeve that engages with the L-shaped block.

[0009] As a further embodiment of this utility model, a round rod is welded to one side of each of the two L-shaped blocks, and one end of the round rod passes through the second spring and the fixing block and is welded to a blocking block.

[0010] As a further embodiment of this utility model, two stop bars are fixed to one side of the fiber optic distribution frame body by bolts, and a blocking post is fixed to one side of each of the two sliding plates to block the stop bars by bolts.

[0011] As a further improvement of this utility model, one side of each of the two C-shaped frames is fixed with a blocking plate to limit the movement of the sliding plate by bolts.

[0012] As a further improvement of this utility model, one side of each of the two L-shaped blocks is provided with a rubber pad to increase friction, and one side of the slide is welded with a pull block.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. With the U-shaped frame and limit block, the slide can be reliably fixed in a specific position when the U-shaped frame and the limit block are engaged. This not only ensures the stability of the fiber optic distribution frame during debugging and maintenance, but also greatly facilitates the operator to perform detailed adjustments and maintenance.

[0015] 2. By providing a stop bar and a blocking post, the optical fiber distribution frame body can be allowed to rotate within a certain range while effectively limiting its rotation angle, making it convenient for maintenance personnel to inspect the rear of the optical fiber distribution frame body.

[0016] 3. By incorporating a retaining sleeve and an L-shaped block, the fiber optic distribution frame body can be effectively limited when they engage with each other, preventing it from rotating inside the box and thus ensuring the safety of the optical fiber. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0025] Referring to Figures 1-6, a pull-out fiber optic patch panel includes a housing 1. A hinged cover 3 is connected to one side of the housing 1. C-shaped plates 5 are fixed to the inner walls of both sides of the housing 1 by bolts. Slide plates 6 are provided inside each of the two C-shaped plates 5. A moving component is provided between the C-shaped plates and the slide plates 6 to allow the slide plates 6 to slide within the C-shaped plates 5. The moving component includes multiple rollers 10. Grooves are provided at the top and bottom of the two C-shaped plates 5. The multiple rollers 10 are rotatably connected to the multiple grooves by bearings, and the rollers 10 are in contact with the slide plates 6. Slide grooves 17 are provided at the top and bottom of the two slide plates 6, allowing the slide plates 6 to move within the C-shaped plates 5 through the cooperation of the slide grooves 17 and the grooves. During sliding, the rolling of the rollers 10 effectively reduces the friction between the slide plates 6 and the C-shaped plates 5 when sliding out, thus making the pull-out smoother.

[0026] In this utility model, a fiber optic distribution frame body 7 is rotatably connected to the two sliding plates 6 near the bottom via a bearing. A limit block 15 is bolted to one side of one of the sliding plates 6, and a second inclined surface 16 is provided on one side of the limit block 15. A clearance groove 2 is provided on one side of the housing 1. A slide 11 is slidably connected to one side of one of the C-shaped plates 5, and the slide 11 passes through the clearance groove 2. Both ends of the slide 11 pass through the C-shaped plate 5 and are bolted to a U-shaped frame 14 that matches the limit block 15. A first inclined surface 13 is provided on one side of the U-shaped frame 14, and the first inclined surface 13 can contact the second inclined surface 16. Two first springs 12 are sleeved on the outer side of the slide 11, and both ends of the first springs 12 are fixed to the C-shaped plate 5 and the U-shaped frame 14 respectively. When the flip cover 3 is opened and the fiber optic distribution frame body 7 is pulled, the clamp 18 and the L-shaped block 19... When the fiber optic patch panel 7 engages, the slide plate 6 moves within the C-shaped plate 5, pulling the slide plate 6 out. As the slide plate 6 moves, the second inclined surface 16 of the limiting block 15 contacts the first inclined surface 13 of the U-shaped frame 14, causing the limiting block 15 to press against the U-shaped frame 14, which moves through the slide 11 and compresses the first spring 12, generating a restoring force. When the second inclined surface 16 of the limiting block 15 moves away from the first inclined surface 13 of the U-shaped frame 14, the limiting block 15 will be in the hollow position of the U-shaped frame 14. Therefore, the U-shaped frame 14 will reset due to the restoring force of the first spring 12, causing the limiting block 15 to enter the U-shaped frame 14. The U-shaped frame 14 then abuts against the limiting block 15 through the planar contact between the two surfaces, thus pulling the slide plate 6 out. It can be reliably fixed in a specific position, which not only ensures the stability of the fiber optic distribution frame during debugging and maintenance, but also greatly facilitates operators to perform detailed adjustments and maintenance work.

[0027] Specifically, the top of the fiber optic distribution frame body 7 is bolted with two fixing blocks 20. A second spring 21 is welded to the opposite side of each fixing block 20. An L-shaped block 19 is welded to one end of each second spring 21. The tops of the two sliding plates 6 are bolted with clamping sleeves 18 that engage with the L-shaped blocks 19. A round rod is welded to one side of each adjacent L-shaped block 19. One end of the round rod passes through the second spring 21 and the fixing block 20 and is welded with a blocking block. Two stop bars 8 are bolted to one side of the fiber optic distribution frame body 7. A blocking post 9, which blocks the stop bars 8, is bolted to one side of each adjacent sliding plate 6. By pushing the two L-shaped blocks 19 towards the center to disengage them from the clamping sleeves 18, and simultaneously rotating the fiber optic distribution frame body 7 so that the stop bars 8 contact the blocking posts 9, the fiber optic distribution frame body 7 can rotate within a certain range while effectively limiting its rotation angle. This allows maintenance personnel to easily access and operate the fiber optic distribution frame body 7. Maintenance is carried out at the rear. After maintenance is completed, the fiber optic patch panel body 7 is rotated and the two L-shaped blocks 19 are pushed so that they can be simultaneously inserted into the sleeve 18. The elastic force of the second spring 21 makes them tightly locked, which can effectively limit the fiber optic patch panel body 7 and prevent it from rotating in the box 1, thereby ensuring the safety of the fiber optic cable.

[0028] In particular, one side of each of the two C-shaped frames 5 is fixed with a stop plate 4 to limit the sliding plate 6. The stop plate 4 prevents the sliding plate 6 from sliding out, thereby increasing the safety of the device. One side of each of the two L-shaped blocks 19 is provided with a rubber pad to increase friction. The rubber pad increases friction and reduces slippage. One side of the slide 11 is welded with a pull block. The pull block increases the contact area and increases the applicability during use.

[0029] Working principle: When the flip cover 3 is opened, the fiber optic patch panel body 7 is pulled. At this time, because the ferrule 18 engages with the L-shaped block 19, the fiber optic patch panel body 7 will drive the slide plate 6 to move within the C-shaped plate 5, thereby pulling out the slide plate 6. When the slide plate 6 moves, the second inclined surface 16 of the limiting block 15 contacts the first inclined surface 13 of the U-shaped frame 14, which will cause the limiting block 15 to squeeze the U-shaped frame 14 to move through the slide 11 and squeeze the first spring 12 to generate a restoring elastic force. When the second inclined surface 16 of the limiting block 15 moves to disengage from the first inclined surface 13 of the U-shaped frame 14, the limiting block 15 will be in the hollow position of the U-shaped frame 14. Therefore, the U-shaped frame 14 will be reset due to the restoring elastic force of the first spring 12, causing the limiting block 15 to enter the U-shaped frame 14, thereby connecting the U-shaped frame 14 and the limiting block 15. The plane fits against the limiting block 15 to block it, thereby reliably fixing the slide plate 6 in a specific position. This not only ensures the stability of the fiber optic distribution frame during debugging and maintenance, but also greatly facilitates the operator to perform detailed adjustments and maintenance. Subsequently, by pushing the two L-shaped blocks 19 towards the center to disengage them from the sleeve 18, and at the same time rotating the fiber optic distribution frame body 7 so that its stop bar 8 contacts the blocking post 9, the fiber optic distribution frame body 7 can rotate within a certain range while effectively limiting its rotation angle, allowing maintenance personnel to easily inspect the rear of the fiber optic distribution frame body 7.

[0030] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
