Description

Technical Field

[0001] This utility model relates to the technical field of winding, and in particular to winding drums. Background Technology

[0002] The winding spool is mainly used in devices for winding the steel wire transmission of shading nets in breeding greenhouses, such as... Figure 9 As shown, the process involves first drilling holes in the main shaft, then fitting the winding drum onto the main shaft, fixing the winding drum to the main shaft by passing bolts through the winding drum and the main shaft, and finally winding the steel wire around the winding drum for use.

[0003] However, during use, it was found that the existing winding drum structure is relatively simple. Installation requires drilling holes in the main shaft, which is time-consuming and laborious, and damages the strength of the main shaft. Furthermore, it is inconvenient to disassemble. In addition, it is inconvenient to fix the ends of the steel wire when winding it, resulting in poor practicality. Therefore, it is urgent to improve the existing winding drum to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a winding drum that uses a locking mechanism in conjunction with a fixing mechanism to install the winding mechanism on the main shaft, eliminating the need to drill holes in the main shaft and improving the ease of installation and disassembly.

[0005] The present invention provides a winding drum, which includes a locking mechanism; it also includes a winding mechanism and a fixing mechanism, both of which are mounted on the winding mechanism.

[0006] The fixing mechanism includes multiple sets of square fixing members, which are respectively installed on the left and right sides of the winding mechanism, and each set of square fixing members has an arc-shaped groove in the middle.

[0007] The locking mechanism, together with the fixing mechanism, mounts the winding mechanism onto the spindle without the need for drilling holes in the spindle, thus improving the ease of installation and disassembly.

[0008] Preferably, the winding mechanism includes a winding drum assembly one and a winding drum assembly two, which are fastened together; the winding drum assembly one and the winding drum assembly two are fastened together so that the winding drum assembly one and the winding drum assembly two wrap around the main shaft.

[0009] Preferably, both the first winding drum assembly and the second winding drum assembly have limiting grooves and protrusions on their fastening surfaces. This facilitates the positioning of the first winding drum assembly and the second winding drum assembly during fastening, allowing the protrusions on the first winding drum assembly to engage with the limiting grooves on the second winding drum assembly, and vice versa. This improves the ease of installation for the first winding drum assembly and the second winding drum assembly.

[0010] Preferably, both the left and right ends of the first winding drum assembly and the second winding drum assembly are provided with arc-shaped protrusions, and both the surface of the first winding drum assembly and the second winding drum assembly are provided with wire grooves; this facilitates the limiting of the steel wire, thereby improving the convenience of winding the steel wire.

[0011] Preferably, reinforcing ribs are provided on the inner walls of both the first winding drum assembly and the second winding drum assembly; thereby improving the strength of the first winding drum assembly and the second winding drum assembly, and increasing the contact surface of the first winding drum assembly and the second winding drum assembly.

[0012] Preferably, one set of the two opposing square fasteners is provided with a fixing groove, and the other set is provided with an inclined surface; the end of the steel wire is inserted into the fixing groove, and then a wedge is used to guide it into the fixing groove through the inclined surface to squeeze and limit the end of the steel wire.

[0013] Preferably, the locking mechanism includes two sets of U-shaped clips, two sets of U-shaped clip fasteners, and multiple sets of locking nuts. The two sets of U-shaped clips are respectively located in multiple sets of arc-shaped grooves, and the ends of the two sets of U-shaped clips are respectively inserted into the two sets of U-shaped clip fasteners. The multiple sets of locking nuts are respectively threaded onto the ends of the two sets of U-shaped clips. After the first winding drum assembly and the second winding drum assembly are fastened onto the main shaft, the U-shaped clips are inserted into the arc-shaped grooves, and the two ends of the U-shaped clips pass through the U-shaped clip fasteners, so that the U-shaped clip fasteners are close to the square fasteners. Then, the locking nuts are threaded onto the ends of the U-shaped clips, so that the U-shaped clips and U-shaped clip fasteners cooperate with the locking nuts to fasten the first winding drum assembly and the second winding drum assembly.

[0014] Preferably, it also includes a set screw, and each of the multiple sets of arc-shaped grooves has a through hole in the middle. The set screw is threaded onto the U-shaped clip fixing component, and the fastening end of the set screw is located in the through hole. The set screw limits the U-shaped clip fixing component, ensuring the stability of the engagement of the first winding drum assembly and the second winding drum assembly.

[0015] Preferably, the fastening end of the set screw has an internal hexagonal structure; this facilitates the installation and removal of the set screw using a hex wrench.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Limiting and fastening are used to ensure the accuracy of the winding drum assembly. U-shaped clips and U-shaped fasteners are used to fasten the winding drum to the main shaft, improving the ease of installation.

[0018] 2. Square fasteners with arc-shaped grooves are used in conjunction with set screws to limit the U-shaped clip fixing parts, preventing the U-shaped clips and U-shaped clip fixing parts from being misaligned, thus ensuring the stability of the winding drum;

[0019] 3. The internal structure is reinforced with ribs to improve the support strength of the winding drum;

[0020] 4. The pre-set fixing groove and inclined surface facilitate the fixing of the end of the steel wire. Attached Figure Description
