Description
Technical Field
[0001] The utility model belongs to the technical field of pay-off wheels, and particularly relates to a flame-retardant nylon pay-off wheel. Background Art
[0002] A pay-off reel is a device used during the laying of cables, wires, optical fibers, and other wires. It supports and rotates the reel to facilitate the smooth laying of the wire. Pay-off reels are used in many industries, such as power installation, telecommunications engineering, and network cabling.
[0003] Some existing pay-off reels are simple, with a manually rotating bracket. This makes it difficult to precisely control the wire during reeling, causing it to easily become tangled or even knotted. This often requires manual untangling, making it inconvenient to use. Therefore, a new flame-retardant nylon pay-off reel is needed. Utility Model Content
[0004] In order to solve the above problems, the utility model discloses a flame retardant nylon pay-off reel.
[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:
[0006] A flame-retardant nylon pay-off wheel comprises a base, the top of the base is rotatably connected to a mounting frame with a vertical rotation axis, a cross bar of the mounting frame is rotatably mounted with a plug-in cylinder, and a plurality of plug-in strips parallel to the axis of the plug-in cylinder are extended from the outer side wall of the plug-in cylinder, the plug-in cylinder is coaxially plugged with a wire cup wheel, a one-way rotation mechanism for controlling the pay-off is installed between the mounting frame and the plug-in cylinder, the mounting frame is installed with a guide mechanism whose rotation axis is coaxial with the axis of the plug-in cylinder; the guide mechanism comprises: a rotating arm rotatably connected to the mounting frame, the T-shaped end of the rotating arm is elastically and slidably mounted with two optical axes parallel to the axis of the plug-in cylinder, each optical axis is slidably mounted with a guide clamping wheel provided with an annular groove, the mounting frame is threadedly connected with a fixing bolt coaxial with the axis of the plug-in cylinder, and the rotating arm is arranged between the mounting frame and the fixing bolt.
[0007] As a preferred technical solution of the present invention, each end of the optical axis slidably inserted into the rotating arm is fixedly connected to a limit slider, each limit slider is connected to a second spring in a compressed state, and the two second springs are respectively arranged at both ends of the T-shaped end of the rotating arm.
[0008] As a preferred technical solution of the present invention, the fixing bolt is extended with a wrench perpendicular to its own rotation axis.
[0009] As a preferred technical solution of the present invention, the one-way rotation mechanism includes: a ratchet coaxially fixedly mounted on one end of the plug-in cylinder, the ratchet is adapted to have an L-shaped pawl, and the bent portion of the L-shaped pawl is rotatably connected to the mounting frame, the mounting frame is extended with a platform adapted to the L-shaped pawl, and an elastically bent spring is provided between the platform and the L-shaped pawl.
[0010] As a preferred technical solution of the present invention, the mounting frame is fixedly plugged with a fixed shaft, and the fixed shaft is rotationally connected to the bent portion of the L-shaped pawl.
[0011] As a preferred technical solution of the present invention, a limiting mechanism is installed at the end of the crossbar of the mounting frame away from the one-way rotation mechanism.
[0012] As an optimal technical solution of the present invention, the limiting mechanism includes: a mounting seat fixed at the end of the cross bar of the mounting frame, two mirror-imaged rounded sliders are slidably connected to the inner cavity of the mounting seat, and a compressed first spring is arranged between the two rounded sliders.
[0013] The beneficial effects of the utility model are:
[0014] 1. When paying out the wire, use a certain force to pull the free end of the wire, and the spool wheel will rotate to pay out the wire. At the same time, the mounting frame rotates freely, and the two guide wheels slide along the optical axis within a certain range, so that the movement direction of the wire points to the pulling direction. Because the spool wheel rotates only when the wire is pulled with a certain force, the wire will be released, which reduces the wire entanglement caused by excessive rotation of the spool wheel during the release.
[0015] 2. When you stop pulling the wire, the L-shaped pawl elastically clamps the ratchet, and the splice barrel and the spool wheel cannot rotate freely. At the same time, the free end of the wire is clamped by the two guide wheels. Thanks to the fact that the free end of the wire and the spool wheel are fixed to a certain extent when you stop pulling the wire, the spool wheel cannot rotate with the free end of the wire, reducing the resulting entanglement and knotting of the wire.

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.
[0030] See also Figure 1-7 A flame-retardant nylon pay-off reel comprises a base 1, the top of which is rotatably connected to a mounting frame 2 with a vertical rotation axis. The four corners of the base 1 are provided with mounting holes for inserting bolts or ground nails for fixing. The base 1 and the mounting frame 2 are rotatably connected via bearings. A plug-in barrel 3 is rotatably mounted on the crossbar of the mounting frame 2, and several inserts extending from the outer wall of the plug-in barrel 3 are parallel to the axis of the plug-in barrel 3. In the embodiment shown in the accompanying drawings, two inserts are evenly distributed on the outer wall of the plug-in barrel 3. The crossbar of the mounting frame 2 and the plug-in barrel 3 are rotatably connected via several bearings. A wire cup wheel 5 is coaxially connected to the plug-in barrel 3, and a one-way rotation mechanism 4 for controlling the pay-off is installed between the mounting frame 2 and the plug-in barrel 3. The one-way rotation mechanism 4 is used to control the rotation and pay-off of the wire cup wheel 5. The mounting frame 2 is equipped with a guide mechanism 7 whose rotation axis is coaxial with the axis of the plug-in barrel 3. The base 1, mounting frame 2, plug-in barrel 3, and the wire cup wheel 5 are made of flame-retardant nylon, which reduces the overall weight while ensuring structural strength.
[0031] The one-way rotation mechanism 4 includes: a ratchet 401 coaxially fixedly mounted on one end of the plug-in barrel 3. The ratchet 401 is adapted to be fitted with an L-shaped pawl 402, and the bent portion of the L-shaped pawl 402 is rotatably connected to the mounting frame 2. Specifically, a fixed shaft 404 is fixedly plugged into the mounting frame 2, and the fixed shaft 404 is rotatably connected to the bent portion of the L-shaped pawl 402. The mounting frame 2 extends with a platform adapted to the L-shaped pawl 402, and an elastically bent spring 403 is provided between the platform and the L-shaped pawl 402. The ratchet 401 can only rotate in one direction due to the elastic fit of the L-shaped pawl 402. The spool wheel 5 can only rotate when a certain force is applied to pull the wire out, thereby reducing the entanglement of the wire caused by the free rotation of the spool wheel 5. Pressing the rounded end of the L-shaped pawl 402 separates the L-shaped pawl 402 from the ratchet 401, allowing the spool wheel 5 to rotate freely.
[0032] The guide mechanism 7 includes a rotating arm 701 rotatably connected to the mounting frame 2. The rotation axis of the rotating arm 701 is coaxial with the axis of the plug-in barrel 3. The rotating arm 701 is made of flame-retardant nylon. Two optical axes 704, parallel to the axis of the plug-in barrel 3, are elastically and slidably mounted on the T-shaped end of the rotating arm 701. Each optical axis 704 is slidably mounted with a guide clamp 705 with an annular groove. The two guide clamps 705 elastically clamp the free end of the wire wound on the spool wheel 5. A fixing bolt 706, coaxial with the axis of the plug-in barrel 3, is threadedly connected to the mounting frame 2, with the rotating arm 701 positioned between the mounting frame 2 and the fixing bolt 706. A wrench extending from the fixing bolt 706, perpendicular to its own rotation axis, facilitates manual rotation of the fixing bolt 706. Loosening the fixing bolt 706 rotates the rotating arm 701, while tightening the fixing bolt 706 secures the rotating arm 701.
[0033] Each optical axis 704, which slides into the end of the rotating arm 701, is fixedly connected to a limiting slider 702. Each limiting slider 702 is connected to a compressed second spring 703. Two second springs 703 are respectively located at each end of the T-shaped end of the rotating arm 701. Under the elastic force of the two second springs 703, two guide clamps 705 elastically clamp the free end of the wire.
[0034] A limiting mechanism 6 is installed at the end of the crossbar of the mounting frame 2 away from the one-way rotation mechanism 4. The limiting mechanism 6 includes: a mounting seat 601 fixed to the end of the crossbar of the mounting frame 2. Two mirror-image-arranged rounded sliders 602 are slidably connected to the inner cavity of the mounting seat 601, and a compressed first spring 603 is provided between the two rounded sliders 602. When the plug-in barrel 3 is inserted into the spool wheel 5, the two rounded sliders 602 retract into the inner cavity of the mounting seat 601. After the spool wheel 5 is fully inserted into the plug-in barrel 3, the two rounded sliders 602 pop out again under the elastic force of the first spring 603, so that the spool wheel 5 cannot move straight along the axis of the plug-in barrel 3.
[0035] Working principle:
[0036] When in use, tighten the fixing bolt 706 to fix the rotating arm 701 at a suitable angle, then insert the spool wheel 5 with the wire wound on it into the plug-in barrel 3, and insert the free end of the wire into the two guide clamping wheels 705 for elastic clamping. When paying out the wire, use a certain force to pull the free end of the wire, and the spool wheel 5 can rotate to pay out the wire. At the same time, the mounting frame 2 rotates freely, and the two guide clamping wheels 705 slide within a certain range along the optical axis 704 to facilitate the moving direction of the wire to point to the pulling direction. When the wire is stopped, the L-shaped pawl 402 elastically clamps the ratchet 401, and the plug-in barrel 3 and the spool wheel 5 cannot rotate freely. At the same time, the free end of the wire is clamped and immobilized by the two guide clamping wheels 705;
[0037] When the spool wheel 5 needs to rotate freely, the rounded end of the L-shaped pawl 402 is pressed to separate the L-shaped pawl 402 from the ratchet 401, and the plug-in barrel 3 and the spool wheel 5 can rotate freely together, so that the spool wheel 5 can rotate and reel in the line.
[0038] It should be noted that the above content only illustrates the technical idea of the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
