[0019] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] This embodiment provides a cable pay-off pulley. Figures 1 to 3 As shown, it includes: a pulley body 1, a first fixing member 2, a second fixing member 3 and a mounting member 4; the mounting member 4 is installed on both sides of the pulley body 1, and is used to lock and position the two ends of the first fixing member 2; the first fixing member 2 is installed on the mounting member 4, and is used to realize the suspension of the pulley body 1 and the construction unit; the second fixing member 3 is installed on the mounting member 4, and is used to realize the locking of the pulley body 1 and the construction unit.

[0024] Specifically, the construction unit in the application is an object or component on one side of the construction operation, rather than a specific unit. It is used to cooperate with the first fixing member 2 or the second fixing member 3 for positioning or deployment. When laying the cable, the cable can pass through the space formed between the first fixing member 2 and the pulley body 1, or through the space formed between the second fixing member 3 and the pulley body 1. The position of the cable penetration is specifically determined by whether the first fixing member 2 and the construction unit are fixed or the second fixing member 3 and the construction unit is fixed. When the pulley body 1 needs to be replaced, the installation component 4 can be manually disassembled for easy and simple operation.

[0025] Using the above-mentioned basic structure, the mounting component 4 includes a side plate 5, a fastening bolt 6, a fastening nut 7 and a flip piece 8; the side plates 5 are arranged on both sides of the pulley body 1, the fastening bolts 6 pass through the side plates 5, the pulley body 1 and the fastening nuts 7 and are threadedly matched, and the flip piece 8 is arranged on one of the side plates 5 and connected to the first fixing piece 2.

[0026] Specifically, the pulley body 1 and the fastening bolt 6 rotate in coordination. When the cable is transmitted, the pulley body 1 rotates accordingly. The side plates 5, the fastening bolts 6 and the fastening nuts 7 are used to position the pulley body 1 and limit the positions on both sides. When the flip member 8 is locked and closed, the first fixing member 2 is in a firmly installed state; when the flip member 8 is opened, one end of the first fixing member 2 is in a disengaged state.

[0027] With the above basic structure, the flip member 8 includes a flip plate 9 and a clamping plate 11 . The flip plate 9 and the side plate 5 are hingedly matched, and the clamping plate 11 is rotatably arranged on the clamping plate 11 .

[0028] Specifically, the snap-fit ​​groove on the card plate 11 and the axis of the first fixing member 2 snap fit with each other, and the through hole on the flip plate 9 is used to fit the first fixing member 2 close to each other. When opening and closing, the card plate 11 rotates around the flip plate 9. After the first fixing member 2 and the flip plate 9 penetrate, the card plate 11 and one end of the first fixing member 2 snap fit and clamp.

[0029] With the above basic structure, the first fixing member 2 includes a rotating shaft 12 and a hook 10 . The rotating shaft 12 and the flip plate 9 are rotatably matched. The clamping plate 11 and the rotating shaft 12 are clamped and matched. The hook 10 is rotatably arranged on the rotating shaft 12 .

[0030] Specifically, one end of the rotating shaft 12 and the side plate 5 are fixed to each other, and the other end of the rotating shaft 12 is axially engaged with the through hole on the flip plate 9. The hook 10 has a certain elastic buckle, which is similar to the principle of a key chain. When the construction unit is engaged in the area of ​​the hook 10, the overall cable unwinding pulley is transmitted through the space formed between the rotating shaft 12 and the pulley body 1.

[0031] With the above basic structure, the second fixing member 3 includes a bottom plate 13 and locking bolts 14. The bottom plate 13 is connected to the side plate 5. The locking bolts 14 penetrate the bottom plate 13 and are pressed against the construction unit.

[0032] Specifically, the space of the bottom plate 13 is used to engage with the specification portion, the engaged area is larger than the height of the clamped object, and the locking bolt 14 is adjusted to tighten the clamped object.

[0033] With the above basic structure, the bottom plate 13 is U-shaped, and a threaded hole through which the locking bolt 14 penetrates is opened on the bottom plate 13 .

[0034] Specifically, the U-shape facilitates movement with the clamped object, and the locking bolt 14 can be manually tightened through the threaded hole.

[0035] With the above basic structure, the side plate 5 is bent, and the middle part of the side plate 5 is convex.

[0036] Specifically, the bending shape of the side plate 5 effectively controls material costs while retaining the need for clamping the pulley body 1 on both sides, and the convex portion facilitates the transmission of cables with larger diameters.

[0037] The first fixing member 2 and the second fixing member 3 can adapt to the hanging state and the regular part clamping installation, which improves the application of the wire-paying pulley in various scenarios of daily use; the mounting component 4 can conveniently disassemble and install and replace the wire-paying pulley, improves the utilization rate of the overall cable wire-paying pulley device, and greatly extends the life and period of the device.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
