Description

Technical Field

[0001] This utility model relates to the field of optical fiber distribution box technology, specifically to an opening and closing structure for an optical fiber distribution box. Background Technology

[0002] In optical fiber communication systems, the optical fiber distribution box is a key device for fiber distribution and management. Its ease of operation and structural stability directly affect construction and maintenance efficiency. Traditional optical fiber distribution boxes typically use a single-sided hinge connection for opening and closing the lid. Operators must hold the lid with one hand and operate it with the other when opening the box for operations such as fiber splicing and line inspection. This not only restricts the free operation of both hands, making the process cumbersome, but also, under prolonged operation or in complex environments, hand fatigue can easily cause the lid to wobble, affecting operational accuracy and safety. Furthermore, the single fixing method of the support components cannot maintain stability under prolonged stress, resulting in poor support performance. Additionally, the traditional support structure cannot be completely stored inside the box when not in use, affecting the closure and handling of the box, reducing the equipment's practicality and portability. Therefore, a new opening and closing structure for the optical fiber distribution box is proposed. Utility Model Content

[0003] This invention proposes an opening and closing structure for an optical fiber distribution box, which solves the problem in related technologies where one hand is needed to hold the opening and closing cover while the other hand operates the optical fiber distribution box, thus restricting the free operation of both hands.

[0004] According to one aspect, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, comprising:

[0005] The optical fiber distribution box body has a rotatable opening and closing cover on its side and a support rod rotatably installed at the bottom inside the optical fiber distribution box body.

[0006] A support rod has a movable groove inside, an extension rod is movable inside the movable groove, and a limit rod is movable inside the extension rod. A limit groove is formed on the bottom surface of the fiber distribution box opening and closing cover, and the limit rod is inserted inside the limit groove.

[0007] For example, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, which further includes: two sets of limiting rods slidably disposed on the extension rod, and the number of limiting grooves is the same as the number of limiting rods.

[0008] For example, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, which further includes: a stop block is provided on the extension rod, and the top ends of both sets of limiting rods are fixedly connected to the stop block.

[0009] For example, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, which further includes: a stabilizing groove is provided on the side of the moving groove, a stabilizing rod is slidably connected inside the stabilizing groove, and the inner wall of the stabilizing rod is fixedly connected to an extension rod.

[0010] For example, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, which further includes: an auxiliary block fixedly connected to the top of the support rod, an auxiliary groove being provided inside the auxiliary block, an insert rod being movably arranged inside the auxiliary groove, and the insert rod passing through the support rod and being inserted into the extension rod.

[0011] For example, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, which further includes: a slot is provided on the extension rod, the insertion rod passes through the support rod and is inserted into the slot, and the inner wall of the slot and the outer wall of the insertion rod are in contact with each other.

[0012] For example, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, which further includes: a spring is provided inside the auxiliary groove, the spring is wound around the outer wall of the insertion rod, the outer wall of the spring is fixedly connected to the inner wall of the auxiliary groove, and the other end of the insertion rod is fixedly connected to the insertion rod.

[0013] For example, at least one embodiment of the present invention provides an opening and closing structure for an optical fiber distribution box, which further includes: the insertion rod passes through the top of the auxiliary block and is fixedly connected to a pull handle, the pull handle is spherically shaped, and the outer wall of the pull handle is provided with anti-slip texture.

[0014] The working principle and beneficial effects of this utility model are as follows: In terms of operational convenience, when operating a traditional optical cable distribution box, the operator needs to support the opening and closing of the cover with one hand, which restricts the operation of the other hand and reduces efficiency. When performing delicate operations such as optical cable splicing and line maintenance, frequent alternation between supporting the cover and operating the box not only prolongs the operation time but also easily leads to errors due to hand fatigue. This opening and closing structure achieves stable fixation of the opening and closing cover in three steps: first, the support rod stored at the bottom of the box is turned out and adjusted to a suitable angle; then, the extension rod is pulled out to the corresponding position; finally, the limiting rod is pushed into the limiting groove. This process is simple to operate, completely freeing the operator's hands and allowing multiple tools to be used simultaneously for continuous operation. For example, when splicing optical cables, optical fiber stripping, cutting, and splicing can be completed simultaneously without interrupting the process. Compared with the traditional operation method, the operation efficiency is significantly improved and the operation time is greatly shortened.

[0015] In terms of structural stability and equipment reliability, this opening and closing structure employs multiple design features to ensure performance. Two sets of limiting rods and limiting slots form multi-point fixation, which, compared to traditional single-point support, distributes force more evenly and effectively resists external interference such as wind and collisions, ensuring the opening and closing cover is stable and does not wobble. The stabilizing rod and stabilizing slot work together to limit the swing of the extension rod, keeping it in a straight line and further enhancing support stability. When the extension rod is in the supported state, the insertion rod and slot are tightly engaged, and it is not easy to retract even under long-term load. In addition, the stop block prevents the limiting rod from falling off, ensuring the normal operation of the limiting structure. The spring-driven insertion rod automatically resets, facilitating repeated operation. The spherical anti-slip pull handle design is ergonomic, allowing for easy operation even with wet hands or while wearing gloves, reducing errors. When not in use, the support rod and extension rod can be completely stored inside the box without affecting the closing of the opening and closing cover, facilitating transportation and storage, reducing the risk of equipment damage, and comprehensively improving the service life and operational reliability of the equipment.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Refer to the instruction manual appendix Figure 1-5An opening and closing structure for an optical fiber distribution box includes an optical fiber distribution box body 1, an opening and closing cover 2 rotatably mounted on the side of the optical fiber distribution box body 1, and a support rod 3 rotatably mounted at the bottom inside the optical fiber distribution box body 1. The opening and closing cover 2 is mounted on the side of the optical fiber distribution box body 1 via common rotating connection components such as hinges. This connection method allows the opening and closing cover 2 to rotate around the side, realizing the opening and closing of the box. At the bottom inside the optical fiber distribution box body 1, a support rod 3 is also mounted using a rotating connection structure. The support rod 3 can be stored inside the box when not in use, without occupying extra space, and can be rotated out to a designated position when in use.

[0030] The support rod 3 has a longitudinally extending groove 4 inside. The dimensions of the groove 4 are precisely designed so that its internal space matches the external dimensions of the extension rod 5, allowing the extension rod 5 to move axially within the groove 4. The extension rod 5 has a space inside to accommodate the limiting rod 6, which can extend and retract within the extension rod 5. The bottom surface of the fiber distribution box cover 2 has a limiting groove 7 corresponding to the limiting rod 6. The shape and size of the limiting groove 7 match the limiting rod 6, so that when the limiting rod 6 extends, it can be accurately inserted into the limiting groove 7.

[0031] When the operator needs to operate the fiber optic distribution box body 1, first, rotate the support rod 3 out from the bottom of the fiber optic distribution box body 1 and adjust it to a suitable angle. Then, grasp the extension rod 5 and pull it out of the moving slot 4 against a certain friction. According to the opening angle and position of the fiber optic distribution box opening and closing cover 2, pull the extension rod 5 to the corresponding position. During this process, the limiting rod 6 will move with the extension rod 5. When the extension rod 5 reaches the appropriate position, push the limiting rod 6 to extend it and insert it into the limiting slot 7 at the bottom of the fiber optic distribution box opening and closing cover 2. The opening and closing state of the fiber distribution box cover 2 is fixed inside, so that the operator does not need to support the fiber distribution box cover 2 with his hands and can focus on the operation inside the box, which simplifies the operation process. For example, when performing optical cable splicing, line inspection and other operations, both hands can operate the tools freely, which improves the operation efficiency. After the operation is completed, the limiting rod 6 is pulled out from the limiting groove 7 and retracted into the extension rod 5, and then the extension rod 5 is pushed back into the moving groove 4. Finally, the support rod 3 is rotated to be stored back into the box, which does not affect the closing of the fiber distribution box cover 2.

[0032] To further enhance the fixing effect of the extension rod 5 on the fiber distribution box cover 2, two sets of limiting rods 6 are slidably set on the extension rod 5. At the same time, the number of limiting grooves 7 at the bottom of the fiber distribution box cover 2 is the same as the number of limiting rods 6. In actual operation, the two sets of limiting rods 6 are inserted into the corresponding limiting grooves 7 respectively. Compared with a single set of limiting rods 6, the two sets of limiting rods 6 fix the fiber distribution box cover 2 from different positions, disperse the force points, effectively prevent the fiber distribution box cover 2 from shaking or shifting in the open and closed state, and significantly enhance the fixing effect.

[0033] A stop block 8 is provided on the extension rod 5. The top ends of the two sets of limit rods 6 are fixedly connected to the stop block 8 by welding or bolt connection. When the limit rod 6 slides in the extension rod 5, the stop block 8 acts as a block to prevent the limit rod 6 from falling off the top of the extension rod 5, ensuring that the limit rod 6 always slides normally in the extension rod 5, ensuring stable operation of the equipment, and avoiding fixation failure due to the limit rod 6 falling off.

[0034] The moving groove 4 has a stabilizing groove 9 on its side. The shape and size of the stabilizing groove 9 are adapted to the stabilizing rod 10. The stabilizing rod 10 can slide in the stabilizing groove 9. The inner wall of the stabilizing rod 10 is fixed to the extension rod 5 by welding, bonding or other means. When the extension rod 5 moves in the moving groove 4, the stabilizing rod 10 slides synchronously in the stabilizing groove 9. The cooperation between the stabilizing rod 10 and the stabilizing groove 9 restricts the swaying of the extension rod 5 when it moves, so that it can only move in a predetermined direction. At the same time, it prevents the extension rod 5 from completely detaching from the moving groove 4, and further ensures the stable operation of the equipment from a structural point of view.

[0035] An auxiliary block 11 is fixedly connected to the top of the support rod 3. An auxiliary groove 12 is provided inside the auxiliary block 11. A movable insertion rod 13 is provided in the auxiliary groove 12. The length of the insertion rod 13 is designed so that it can pass through the support rod 3 and be inserted into the extension rod 5. When the extension rod 5 is pulled out to support the fiber distribution box opening and closing cover 2, the insertion rod 13 is inserted into the extension rod 5, which increases the fixing strength of the extension rod 5, prevents it from retracting during the support process, and ensures the fixing effect of the extension rod 5 when it is in the support state.

[0036] The extension rod 5 has a slot 14. The inner wall of the slot 14 fits the outer wall of the insertion rod 13. When the insertion rod 13 passes through the support rod 3 and is inserted into the slot 14, the two fit tightly together. The insertion of the insertion rod 13 into the slot 14 further enhances the fixing effect of the extension rod 5 in the moving groove 4. When the position of the extension rod 5 needs to be adjusted, the insertion rod 13 is pulled out of the slot 14, and the extension rod 5 can slide freely in the moving groove 4, realizing the flexible switching between the fixed state and the sliding state of the extension rod 5.

[0037] A spring 15 is provided inside the auxiliary groove 12. The spring 15 is wrapped around the outer wall of the insertion rod 13, with one end fixed to the inner wall of the auxiliary groove 12 and the other end fixed to the insertion rod 13. When the insertion rod 13 is inserted into the slot 14 of the extension rod 5, the spring 15 is in a compressed state, and the elastic force generated pushes the insertion rod 13 downward, so that it is tightly connected with the slot 14. When the insertion rod 13 needs to be pulled out, it is pulled upward against the elastic force of the spring 15. After the operation is completed, the elastic restoring force of the spring 15 makes the insertion rod 13 automatically return to its original position, realizing repeated operation of the insertion rod 13 and improving the convenience of operation.

[0038] The insertion rod 13 passes through the top of the auxiliary block 11 and is fixedly connected to a pull handle 16. The pull handle 16 is designed in a spherical shape for easy gripping by the operator. The outer wall of the pull handle 16 is provided with anti-slip texture. When the operator grips the pull handle 16 to move the insertion rod 13, the anti-slip texture increases the friction between the hand and the pull handle 16, preventing the rod from slipping out of the hand during operation, making the movement of the insertion rod 13 more convenient and safer.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
