Description

Technical Field

[0001] The embodiments of this utility model relate to the field of optical fiber distribution box technology, specifically, to a cylindrical optical fiber distribution box. Background Technology

[0002] Fiber optic distribution boxes are interface devices used outdoors, in corridors, or indoors to connect trunk optical cables and distribution optical cables. Fiber optic distribution boxes must be able to work reliably in the specified environment, and their enclosures must be able to withstand a vertical pressure of no more than 500N.

[0003] The utility model disclosed in CN221039559U is a cylindrical optical cable distribution box, which includes a distribution box body, a connecting seat fixedly installed on the rear side of the distribution box body, and a clamping box fixedly installed on the rear side of the connecting seat; a bidirectional mechanism is provided inside the clamping box, and a rocker mechanism is provided on the right side of the clamping box.

[0004] The aforementioned application document uses a bidirectional mechanism and a clamping mechanism to install and fix the fiber distribution box body onto a post or utility pole, enabling convenient installation of the fiber distribution box body. However, its overall fiber distribution and positioning effect on the optical cable is poor, which is not conducive to the installation of the optical cable and therefore needs to be improved. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this utility model provide a cylindrical optical cable distribution box, which solves the technical problems in related technologies / existing technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a cylindrical optical cable distribution box, comprising: a box body, a hinge provided on the side of the box body, a door rotatably installed at the front end of the box body via the hinge, a mounting plate fixedly connected to the top of the box body, a through hole provided at the bottom of the box body, and a convenient cable splitting mechanism provided inside the through hole; the convenient cable splitting mechanism includes a fixed cylinder and a fixed block, the fixed cylinder being fixedly connected inside the through hole, a slot being provided at the front end of the fixed cylinder, a compression spring being provided inside the slot, a slot being provided on the inner side wall of the slot, a pressure rod being slidably connected through the inner side wall of the slot, the bottom of the fixed block being fixedly connected to the inner bottom of the box body, a sliding rod being slidably connected through the rear end of the fixed block, a movable cylinder being fixedly connected to the rear end of the sliding rod, an insertion block being fixedly connected to the rear end of the movable cylinder, a groove being provided on the side of the insertion block, a telescopic spring being provided inside the groove, an arc-shaped block being elastically connected inside the groove via the telescopic spring, and a deceleration mechanism being provided at the front end of the movable cylinder.

[0007] For example, in at least one embodiment of the present invention, a cylindrical optical fiber distribution box is provided, which further includes: the opening size of the slot is equal to the size of the plug, and the depth of the slot is greater than the length of the plug, so that the plug can be inserted into the slot.

[0008] The opening size of the slot is equal to the opening size of the groove, and the depth of the groove is greater than the length of the arc-shaped block. When the arc-shaped block is stuck in the slot, the fixed cylinder and the moving cylinder cannot be separated.

[0009] Both the fixed cylinder and the movable cylinder are semi-circular in shape and are the same size. The optical cable is limited by combining the semi-circular fixed cylinder and the movable cylinder.

[0010] The arc surface of the arc block faces the direction of the fixed cylinder. The arc block initially protrudes from the groove, and when the arc surface of the arc block is squeezed, it will move into the groove.

[0011] A limit block is provided at the end of the slide rod away from the moving cylinder, and a sealing plate is provided on the surface of the moving cylinder. When the moving cylinder and the fixed cylinder are combined, the sealing plate will close the through hole.

[0012] According to another aspect, at least one embodiment of the present invention also provides a deceleration mechanism, comprising: a connecting plate and a deceleration block, wherein the connecting plate is fixedly connected to the front end of the moving cylinder, a rotating shaft is rotatably connected to the bottom of the connecting plate, a rotating plate is fixedly connected to the surface of the rotating shaft, an elastic rope is fixedly connected to the rear end of the rotating plate, and the deceleration block is fixedly connected to the top of the fixed block.

[0013] For example, in at least one embodiment of the present invention, a cylindrical optical fiber distribution box is provided, which further includes: the end of the rotating plate away from the rotating shaft is arc-shaped, and the end of the rotating plate away from the rotating shaft is close to the top of the fixed block. When the rotating plate moves with the connecting plate, the arc-shaped end of the rotating plate will contact the deceleration block on the top of the fixed block.

[0014] The rotating shaft is located at the top front end of the rotating plate, and the end of the elastic rope away from the rotating plate is fixedly connected to the bottom of the connecting plate. The position of the rotating shaft allows the rotating plate to deflect only towards the front end.

[0015] The deceleration block is semi-cylindrical in shape, and the top of the deceleration block is smooth. When the arc-shaped end of the rotating plate is squeezed against the semi-cylindrical rubber deceleration block, a large resistance will be generated.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. This utility model features a convenient cable splitting mechanism, which allows for fiber splitting and limiting of the optical cable. When the optical cable needs to be split and limited, the optical cable is passed between the fixed cylinder and the moving cylinder, and the moving cylinder is pushed to the rear end to merge with the fixed cylinder. At this time, with the cooperation of components such as the insertion block, slot, arc block, and card slot, the moving cylinder and the fixed cylinder cannot be separated, thus limiting the optical cable. When the optical cable needs to be removed, the pressure rods on both sides of the fixed cylinder are pressed, and the moving cylinder will automatically move a distance to the front end to separate from the fixed cylinder. Overall, it is more convenient to use.

[0018] 2. By incorporating a slowing mechanism, this utility model achieves the following: when the pressure rods on both sides of the fixed cylinder are pressed, and the compressed spring rebounds, causing the moving cylinder to move a certain distance towards the front, the speed of the moving cylinder moving towards the front is slowed down through the cooperation of components such as the connecting plate, rotating shaft, and rotating plate. This prevents the moving cylinder from moving too fast and squeezing the operator's hand, effectively improving overall safety. Attached Figure Description

[0032] 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.

[0033] like Figures 1-6 As shown, this invention illustrates a cylindrical optical cable distribution box according to one embodiment, comprising: a box body 1, a hinge 2 on the side of the box body 1, a door 3 rotatably mounted on the front end of the box body 1 via the hinge 2, a mounting plate 4 fixedly connected to the top of the box body 1, a through hole 5 at the bottom of the box body 1, and a convenient cable splitting mechanism 6 disposed inside the through hole 5; the convenient cable splitting mechanism 6 includes a fixed cylinder 61 and a fixed block 66, the fixed cylinder 61 being fixedly connected inside the through hole 5, a slot 62 at the front end of the fixed cylinder 61, a compression spring 63 disposed inside the slot 62, and the slot 62 containing a compression spring 63. A slot 64 is provided on the side wall. A pressure rod 65 is slidably connected through the inner side wall of the slot 64. The bottom of the fixing block 66 is fixedly connected to the inner bottom of the box 1. A slide rod 67 is slidably connected through the rear end of the fixing block 66. A moving cylinder 68 is fixedly connected to the rear end of the slide rod 67. An insert block 69 is fixedly connected to the rear end of the moving cylinder 68. A groove 610 is provided on the side of the insert block 69. A telescopic spring 611 is provided inside the groove 610. An arc-shaped block 612 is elastically connected inside the groove 610 through the telescopic spring 611. A slowing mechanism 7 is provided at the front end of the moving cylinder 68.

[0034] In some examples, the opening size of slot 62 is equal to the size of insert 69, and the depth of slot 62 is greater than the length of insert 69, so that insert 69 can be inserted into slot 62.

[0035] The opening size of the slot 64 is equal to the opening size of the groove 610. The depth of the groove 610 is greater than the length of the arc block 612. When the arc block 612 is stuck in the slot 64, the fixed cylinder 61 and the movable cylinder 68 cannot be separated.

[0036] Both the fixed cylinder 61 and the movable cylinder 68 are semi-circular in shape, and the fixed cylinder 61 and the movable cylinder 68 are the same size. The optical cable is limited by the semi-circular fixed cylinder 61 and the movable cylinder 68 combined together.

[0037] The arc surface of the arc block 612 faces the direction of the fixed cylinder 61. In the initial state, the arc block 612 protrudes from the groove 610. When the arc surface of the arc block 612 is squeezed, it will move into the groove 610.

[0038] A limit block is provided at the end of the slide rod 67 away from the moving cylinder 68. A sealing plate is provided on the surface of the moving cylinder 68. When the moving cylinder 68 and the fixed cylinder 61 are combined, the sealing plate will close the through hole 5.

[0039] For example, as shown in Figures 1-6, when fiber separation and positioning of the optical cable are required, the optical cable is passed between the fixed cylinder 61 and the movable cylinder 68, and the movable cylinder 68 is pushed towards the rear. When the movable cylinder 68 moves towards the rear and merges with the fixed cylinder 61, the insert block 69 will be inserted into the slot 62, and the compression spring 63 will be compressed. Initially, the arc surface of the arc-shaped block 612 will be squeezed and retract into the groove 610, and the telescopic spring 611 will be compressed. When the groove 610 coincides with the slot 64, the telescopic spring 611 will rebound and drive the arc-shaped block. When 612 is inserted into the slot 64, the moving cylinder 68 and the fixed cylinder 61 are joined together and cannot be separated. The optical cable is limited by the semi-circular fixed cylinder 61 and the moving cylinder 68 being joined together. When the optical cable needs to be removed, press the pressure rods 65 on both sides of the fixed cylinder 61. The pressure rods 65 push the arc-shaped block 612 out of the slot 64. When the arc-shaped block 612 leaves the slot 64, the compression spring 63 rebounds and drives the insert block 69 and the moving cylinder 68 to move forward and separate from the fixed cylinder 61. The overall operation is simple and easy to use.

[0040] like Figures 1-6 As shown, the slowing mechanism 7 in another embodiment of the present invention includes: a connecting plate 71 and a deceleration block 75. The connecting plate 71 is fixedly connected to the front end of the moving cylinder 68. A rotating shaft 72 is rotatably connected to the bottom of the connecting plate 71. A rotating plate 73 is fixedly connected to the surface of the rotating shaft 72. An elastic rope 74 is fixedly connected to the rear end of the rotating plate 73. The deceleration block 75 is fixedly connected to the top of the fixed block 66.

[0041] In some examples, the end of the rotating plate 73 away from the rotating shaft 72 is arc-shaped, and the end of the rotating plate 73 away from the rotating shaft 72 is close to the top of the fixed block 66. When the rotating plate 73 moves with the connecting plate 71, its arc-shaped end will contact the deceleration block 75 on the top of the fixed block 66.

[0042] The rotating shaft 72 is located at the top front end of the rotating plate 73. The end of the elastic rope 74 away from the rotating plate 73 is fixedly connected to the bottom of the connecting plate 71. The position of the rotating shaft 72 allows the rotating plate 73 to deflect only towards the front end.

[0043] The deceleration block 75 is semi-cylindrical in shape, and the top of the deceleration block 75 is smooth. When the arc-shaped end of the rotating plate 73 is squeezed against the semi-cylindrical rubber deceleration block 75, a large resistance will be generated.

[0044] For example, as shown in Figures 1-6, during the process of the moving cylinder 68 moving to the rear and merging with the fixed cylinder 61, the connecting plate 71 moves to the rear along with the moving cylinder 68. At this time, the rotating plate 73 moves to the rear and contacts the deceleration block 75 on the top of the fixed block 66. At this time, the rear end of the rotating plate 73 is subjected to force and will deflect to the front, so that it will not squeeze too much with the deceleration block 75 and generate a large resistance. Subsequently, the elastic rope 74 drives the rotating plate 73 to return to its original position. When the compression spring 63 rebounds and drives the insert block 69 to move to the front and separate from the fixed cylinder 61, the rotating plate 73 moves to the front and contacts the deceleration block 75 again. At this time, the rotating plate 73 cannot deflect to the rear and will squeeze with the deceleration block 75, generating a large resistance. This slows down the speed of the moving cylinder 68 moving to the front, prevents collision with the operator's hand, and improves overall safety.

[0045] 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.
