Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber distribution integration devices, specifically a pull-out optical fiber distribution integration device. Background Technology

[0002] Fiber optic distribution unit (Fiber Optic Distribution Unit) is a device used in fiber optic communication networks for terminating, protecting, connecting, and managing optical cables and fibers, playing a crucial role in fiber optic communication systems. It integrates multiple fiber optic distribution-related functions. For example, it integrates cable fixing and protection functions, allowing the fiber optic cable to be introduced and fixed to the rack, protecting the cable and its fiber cores from damage, and insulating the metal parts of the cable from the metal rack. It also reliably connects the fixed cable's metal sheath and reinforcing core to a high-voltage grounding device. It has fiber optic termination functions, facilitating the splicing, construction, installation, and maintenance of fiber optic cores and pigtails. It has a patching function, allowing for quick and easy adjustment of the fiber core sequence and modification of the optical transmission system's path sequence via fiber optic patch cord connectors. It also features fiber optic core and pigtail protection functions, protecting the stripped fiber cores and fixed fibers. To address the unique characteristics of fiber optic cabling and the operational and maintenance needs of practical applications, pull-out type Fiber Optic Distribution Units have been introduced to the market.

[0003] Currently, existing pull-out fiber optic distribution integration devices require high technical skills from operators in practical applications. When pulling out the device, a uniform speed must be maintained, and sudden pulling or pushing should be avoided, otherwise the fiber optic cable or connector may be damaged. This poses a learning cost for novice maintenance personnel. In addition, the pull-out bracket material of some low-cost products is not strong enough. Long-term load-bearing, such as high-density cables, may cause deformation and affect the bending radius of the fiber optic cable. Therefore, we propose a pull-out fiber optic distribution integration device. Utility Model Content

[0004] The purpose of this invention is to provide a retractable fiber optic distribution integration device, which has the advantages of easy operation, reduced technical requirements, and improved support material strength. It solves the problem that existing retractable fiber optic distribution integration devices require high technical skills from operators in practical applications. When pulling out the device, a uniform speed must be maintained and sudden pulling or pushing should be avoided, otherwise the fiber optic cable or connector may be damaged. This poses a learning cost for novice maintenance personnel. In addition, the pull-out support material of some low-cost products is not strong enough, and long-term heavy loads such as high-density cables may cause deformation, affecting the bending radius of the fiber optic cable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pull-out fiber optic distribution integration device, comprising:

[0006] A patch panel housing, wherein damping slide rails are fixedly installed on both the left and right sides inside the patch panel housing, and a patch panel pull-out tray located inside the patch panel housing is fixedly installed on one side of the damping slide rails. Reinforcing strips and reinforcing plates are symmetrically arranged at the upper and lower ends of both the left and right sides of the patch panel pull-out tray, and a toothed plate is fixedly connected to one end of the reinforcing plate.

[0007] The drive cylinders are fixedly installed on the left and right sides inside the wiring frame housing. The middle end of the drive cylinder is movably connected to a rotating shaft through a bearing. A coil spring is fixedly connected between the outer surface of the drive cylinder and the inner wall of the drive cylinder. A gear that meshes with a gear plate is fixedly connected to one side of the rotating shaft.

[0008] A pull plate that is fixedly connected to the front of the patch panel housing.

[0009] Preferably, the drive cylinder is located at the front end inside the wiring frame housing, and the number of drive cylinders is four.

[0010] Preferably, mounting ears are provided at both ends of the front side of the patch panel housing.

[0011] Preferably, the bottom of the inner side of the patch panel pull-out tray is provided with a fiber reel and a fiber melting tray.

[0012] Preferably, positioning slots are provided on both the left and right sides of the front end of the patch panel housing.

[0013] Preferably, both ends of the pull plate are provided with L-shaped movable grooves in plan view, and one end of the movable groove is slidably connected to an L-shaped positioning plate that is adapted to the positioning slot, and one end of the L-shaped positioning plate is a right triangle.

[0014] Preferably, a push plate is fixedly connected to the front of the L-shaped positioning plate, and an arc-shaped spring is provided between one side of the L-shaped positioning plate and the inner wall of the movable groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the setting of the drive cylinder, when the patch panel pull-out tray enters the patch panel housing, the patch panel pull-out tray will drive the toothed plate to move synchronously. When the toothed plate moves, it can drive the rotating shaft to rotate via gears. The rotating shaft can pre-tighten the coil spring, thereby storing elastic potential energy. When the operator drives the patch panel pull-out tray outward via the pull plate, it overcomes the initial static friction of the damping slide rail. Once started, the potential energy stored in the coil spring can be released, and the resulting assist and damping resistance are dynamically balanced. Subsequently, only a light force is needed to maintain the pulling action, and even the remaining stroke can be completed by relying on inertia after releasing the hand. Due to the damping limitation, the movement of the patch panel pull-out tray will not accelerate. When the patch panel pull-out tray moves inward to retract into the patch panel housing via the pull plate, the damping slide rail can provide reverse buffering during the push-back, ensuring the uniform and stable movement of the patch panel pull-out tray, avoiding the situation of sudden pulling and pushing, and reducing the technical difficulty of operation.

[0017] 2. By setting up reinforcing strips and reinforcing plates, this utility model can improve the strength of the patch panel pull-out tray itself, avoiding the situation where insufficient strength of the pull-out bracket material may lead to deformation and affect the bending radius of the optical fiber due to long-term heavy loads such as high-density cables.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0028] Example 1

[0029] Please see Figures 1-5 As shown, this utility model provides a technical solution: a pull-out fiber optic distribution integration device, comprising:

[0030] The patch panel housing 1 has damping slide rails 4 fixedly installed on both the left and right sides inside the patch panel housing 1. A patch panel pull plate 2 located inside the patch panel housing 1 is fixedly installed on one side of the damping slide rail 4. Reinforcing strips 504 and reinforcing plates 505 are symmetrically arranged at the upper and lower ends of both sides of the patch panel pull plate 2. A toothed plate 506 is fixedly connected to one end of the reinforcing plate 505.

[0031] The drive cylinder 5 is fixedly installed on the left and right sides inside the wiring frame housing 1. The middle end of the drive cylinder 5 is movably connected to the rotating shaft 501 through the bearing. The rotating shaft 501 is located between the outer surface of the drive cylinder 5 and the inner wall of the drive cylinder 5 and the coil spring 502 is fixedly connected. A gear 503 that meshes with the toothed plate 506 is fixedly connected to one side of the rotating shaft 501.

[0032] A pull plate 203 is fixedly connected to the front of the patch panel housing 1.

[0033] The drive cylinder 5 is located at the front end inside the patch panel housing 1, and there are four drive cylinders 5. Both ends of the front of the patch panel housing 1 are provided with mounting ears 101. The bottom of the inner side of the patch panel pull-out tray 2 is provided with a fiber reel 201 and a fiber melting tray 202.

[0034] This technical solution: By setting up the damping slide rail 4, the patch panel pull-out plate 2 can move normally within the patch panel housing 1, giving the device the ability to be pulled out and used. Through the setting of the drive cylinder 5, when the patch panel pull-out plate 2 enters the patch panel housing 1, it drives the toothed plate 506 to move synchronously. The toothed plate 506, in turn, drives the rotating shaft 501 to rotate via the gear 503. The rotating shaft 501 pre-tightens the coil spring 502, allowing it to store elastic potential energy. When the operator moves the patch panel pull-out plate 2 outward via the pull plate 203, it overcomes the initial static friction of the damping slide rail 4. Once started, the potential energy stored in the coil spring 502 is released, and the resulting assist and damping resistance are dynamically balanced. Subsequent pulling only requires light force to maintain the pulling action, and the remaining stroke can even be completed by inertia after releasing the hand. The movement of the patch panel pull-out plate 2 is limited by damping. The movement will not accelerate. When the pull plate 203 drives the patch panel pull plate 2 to move inward and retract into the patch panel housing 1, the damping slide rail 4 provides a reverse buffer during the push-back, ensuring the uniform and smooth movement of the patch panel pull plate 2 during the pull-out process. This avoids sudden pulling and pushing and reduces the technical difficulty of operation. The coil spring 502 is pre-tightened when closed and releases energy during the pull-out process, providing assistance in the opposite direction of the pull-out. This can offset part of the damping resistance or load weight, making the operation more effortless. The damping slide rail 4 generates resistance proportional to the speed through fluid (such as silicone oil) or friction elements, suppressing sudden acceleration or deceleration and ensuring smooth movement. The reinforcement strip 504 and reinforcement plate 505 can improve the strength of the patch panel pull plate 2 itself, avoiding the situation where the pull-out bracket material is not strong enough and may deform under long-term heavy loads such as high-density cables, affecting the bending radius of the optical fiber.

[0035] Example 2

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, the front end of the patch panel housing 1 is provided with positioning slots 304 on both the left and right sides. The pull plate 203 is provided with movable slots 3 with an L-shaped planar cross-section on both the left and right ends. One end of the movable slot 3 is slidably connected to an L-shaped positioning plate 302 that is adapted to the positioning slot 304. One end of the L-shaped positioning plate 302 is a right triangle. A push plate 301 is fixedly connected to the front of the L-shaped positioning plate 302. An arc-shaped spring piece 303 is provided between one side of the L-shaped positioning plate 302 and the inner wall of the movable slot 3.

[0037] This technical solution: After the L-shaped positioning plate 302 is driven by the push plate 301 to compress the arc-shaped spring 303 in the movable groove 3, one end of the L-shaped positioning plate 302 will exit the positioning groove 304, thereby eliminating the positioning relationship between the patch panel housing 1 and the patch panel pull-out plate 2, making it easier for the operator to pull out the patch panel pull-out plate 2. After one end of the L-shaped positioning plate 302 is engaged in the positioning groove 304, the positional relationship between the patch panel housing 1 and the patch panel pull-out plate 2 is determined, ensuring the stability of the patch panel pull-out plate 2 within the patch panel housing 1.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
