Description

Technical Field

[0001] The present invention belongs to the technical field of communication line construction, and specifically relates to a butterfly-shaped optical cable retracting and releasing device suitable for multiple scenarios. Background Art

[0002] Butterfly optical cable, also known as leather-line optical cable, has the advantages of low production cost, small structure volume, strong bending and tensile properties, etc. It is currently mainly used in fiber-to-the-home applications, and can also be used as a transmission medium for building instant or local fiber-optic communications in special environments such as military, emergency rescue, and field operations. When the commercial butterfly optical cable is 500 meters or longer, it is generally packaged in a plastic or wooden reel, and the butterfly optical cable is wrapped around the cable reel shaft to form an optical cable reel. When the butterfly optical cable is retracted and released, the main means are support rods and mechanical cable racks.

[0003] The existing butterfly-shaped optical cable retracting and releasing device suitable for multiple scenarios uses a support rod to bear the load of the cable, which consumes a lot of physical strength of the operators. It is not suitable for long-distance laying operations and has high requirements for the flatness of the road surface. In military operations, field operations and other situations where the pulley is inconvenient to roll, the reel frame is difficult to move and use, and the horizontal pay-off drum does not have the function of mobile cable laying, and is not suitable for mobile wiring operations in outdoor environments. In view of the problem that the existing cable laying means have a single application scenario and low cable recovery efficiency, the existing means mainly rely on manual manipulation of the cable reel side plate to drive the cable shaft to rotate to recover the optical cable, which has low recovery efficiency and consumes a lot of physical strength of the operators during long-term work.

[0004] To this end, the present invention provides a butterfly-shaped optical cable retracting and releasing device suitable for multiple scenarios. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art and solve the problem of being inconvenient to use in different scenarios, the present invention proposes a butterfly-shaped optical cable retracting and releasing device suitable for multiple scenarios.

[0006] 1. The technical solution adopted by the present invention to solve its technical problems is as follows: A butterfly optical cable retracting and deploying device applicable to multiple scenarios described in the present invention includes a roller support frame. One end of the roller support frame is movably connected to a hand-held support frame. One end of the hand-held support frame is fixedly connected to a grip. Holes are provided on both the roller support frame and the hand-held support frame. Rollers are symmetrically arranged on the roller support frame. A cable management ring is fixedly installed on the roller support frame. A card slot is provided on the roller support frame. A hand-held grip socket is provided on the roller support frame, and the card slot is communicated with the hand-held grip socket. A hand-held grip is fixedly installed inside the hand-held grip socket through bolts. A bearing is provided inside the hand-held grip. A support rod is fixedly installed on the inner ring of the bearing. A limiting plate is fixedly installed on the support rod. A limiting hole is provided on the limiting plate. Support rings are symmetrically arranged on the support rod. A clamping assembly is provided on the support rings. The butterfly optical cable retracting and deploying device applicable to multiple scenarios has three usage forms: fixed type, hand-pushing type, and hand-held type;

[0007] In the fixed type form, an angle is formed between the hand-held support frame and the roller support frame. The connection between the hand-held support frame and the roller support frame is fixed using a pin, and it is used in the fixed type form through the cooperation of the grip and the roller support;

[0008] In the hand-pushing type form, the hand-held support frame and the roller support frame are in the same plane. The connection state is fixed by passing a pin through the hand-held support frame and the roller support frame, and it is used in the hand-pushing type form with the assistance of the rollers for walking;

[0009] In the hand-held type form, the hand-held grips are fixedly installed on both sides of the support rod, clamping the support rod, and the hand-held type form of the butterfly optical cable manual retracting and deploying frame is formed. By adopting the form of two people each holding a hand-held grip on one side, the mobile laying of the butterfly optical cable can be realized.

[0010] Preferably, a positioning pin is provided inside the hand-held grip.

[0011] Preferably, a plug handle pin hole is provided at one end of the support rod, and a detachable grip is installed at one end of the support rod.

[0012] Preferably, a pin is inserted through the limiting hole for positioning the support ring.

[0013] Preferably, a clamping disc is installed on the support ring. Clamping disc sawteeth are provided on one of the clamping discs, and a clamping mechanism is provided on the clamping disc.

[0014] Preferably, the clamping mechanism includes a fixed hook, an adjusting bolt, and a clamping gasket. The fixed hook is fixedly installed on the support disc. The adjusting bolt is threadedly connected inside the fixed hook. The clamping gasket is fixedly connected to one end of the adjusting bolt.

[0015] Preferably, serrations are arranged in an array on the side surface of the clamping gasket.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The butterfly optical cable retracting and deploying device applicable to multiple scenarios described in the present invention has rich application scenarios and has three usage forms: fixed type, hand-pushed type, and hand-held type. The form conversion is rapid and the operation is simple. The fixed type can be used for indoor, outdoor, or vehicle-mounted wiring. At this time, the retracting and deploying frame has a folded appearance, and the user can draw out the optical cable from the retracting and deploying frame to carry out cable deployment; the hand-pushed type is suitable for occasions where the road surface is flat and mobile cable deployment is required, and the user can quickly deploy the cable by pushing the retracting and deploying frame; the hand-held type is suitable for wiring in environments with poor terrain conditions such as military or field operations.

[0018] 2. The butterfly optical cable retracting and deploying device applicable to multiple scenarios described in the present invention has a flexible and effective cable reel fixing method. The cable reel is fixed by a combination of a support rod + a clamping disc + a clamping device. The support rod is equipped with a bearing structure, which can effectively reduce the rolling friction of the support rod and improve the efficiency of cable retracting and deploying; the maximum fixed height of the movable clamping disc for the cable reel is 42 cm, which can be compatible with most current commercial butterfly optical cable reel specifications and has strong adaptability flexibility; the clamping device is tightly combined with the cable reel side plate through pressure and serration structure, which can effectively stabilize the butterfly optical cable reel and effectively prevent the relative displacement between the cable reel and the support rod, thereby causing damage to the cable reel and wire jamming.

[0019] 3. The butterfly optical cable retracting and deploying device applicable to multiple scenarios described in the present invention can assist in efficient cable recovery. A detachable crank can be quickly installed in all three operation forms. The user uses the crank to rotate and recover the butterfly optical cable. Compared with the traditional method of manually rotating the cable reel side plate, the cable recovery speed is flexibly controllable, the physical exertion is smaller, and the recovery speed is faster.

[0020] 4. The butterfly optical cable retracting and deploying device applicable to multiple scenarios described in the present invention has a horn-shaped wire management ring structure design. By adopting the wire management ring design with a horn-shaped appearance, it can effectively prevent the cable from rubbing against the side plate during the cable deployment process. At the same time, compared with the wire management ring design of the spool rack, it causes less wear and physical bending to the outer skin of the optical cable and has stronger protection performance for the optical cable.

A hand-held grip socket 16 is provided on the roller support frame 1, and the card slot 15 is communicated with the hand-held grip socket 16. A hand-held grip 7 is fixedly installed inside the hand-held grip socket 16 through bolts. A bearing 11 is provided inside the hand-held grip 7. A support rod 12 is fixedly installed on the inner ring of the bearing 11. A limit plate 13 is fixedly installed on the support rod 12. A limit hole 14 is provided on the limit plate 13. Support rings 17 are symmetrically arranged on the support rod 12. A clamping assembly is provided on the support rings 17. The butterfly optical cable retracting and deploying device applicable to multiple scenarios can be applied to multiple scenarios, and has three working postures: fixed type, hand-pushing type, and hand-held type, and can adapt to optical cable retracting and deploying operation scenarios in indoor wiring and special environments such as military, emergency rescue, and field operations. The limit plate 13 on the support rod 12 matches the central notch of the support ring 17, which can prevent the clamping plate 18 from rolling relative to the support rod 12. Bearings 11 are installed on both sides of the support rod 12. The hand-held grip 7 contains a groove structure that can tightly fix the bearing 11, so that the rolling resistance of the support rod 12 relative to the hand-held grip 7 is small. The clamping plate 18 is provided with clamping plate serrations 19, and can be stably fixed to the butterfly optical cable reel in cooperation with the fixed hook 20, the clamping gasket 22, and the adjusting bolt 21.

[0032] Use Step 1: Fix the cable reel

[0033] Place the butterfly optical cable reel flat; make the side of the clamping plate 18 without serrations closely adhere to the side plate of the cable reel; put the clamping device on one arm of the clamping plate 18 (each clamping plate includes 3 arms), and make the fixed hook 20 of the clamping device closely adhere to the side plate; place the clamping gasket 22 between the clamping device and the clamping plate serrations 19, and make the serrated side of the clamping gasket 22 fit with the serrations of the clamping plate serrations 19 on the clamping plate 18; install and continuously tighten the adjusting bolt 21 of the clamping device until the pressure formed by the fixed hook 20 and the clamping plate 18 stably fixes the cable reel; install the remaining 5 clamping devices in the same way in sequence.

[0034] Use Step 2: Install the support rod

[0035] After completing the tight connection between the clamping disc 18 and the cable reel, insert the limiting plate 13 of the support rod 12 through the central notch of the support ring 17; insert a pin through the clamping disc 18 and the jack of the limiting hole 14 to prevent relative movement between the cable reel and the support rod 12; install the handgrip 7 on both sides of the support rod 12 and fix the handgrip 7 with the grip screw to clamp the support rod 12. At this time, the portable form of the manual retractable and deployable frame for butterfly optical cables is formed.
