Description

Technical Field

[0001] The present application relates to the field of cable reel handle structures, and in particular to a hidden cable reel handle structure. Background Art

[0002] In the prior art, the wire reel is usually equipped with a crank for wire reeling and unwinding operations. For some large wire reels, mechanical equipment is usually used to drive the wire reeling and unwinding. However, for some small wire reels, a crank is usually fixed on the outside of the wire reel. When in use, the wire reel can be driven to rotate by simply turning the crank to perform wire reeling and unwinding operations. However, these cranks are usually directly exposed to the outside. When the wire reel is not in use, the crank is easily collided and corroded by external factors, thereby shortening the service life of the crank and increasing maintenance costs. The crank directly exposed to the outside also affects the overall appearance of the wire reel. In addition, the exposed crank may also cause accidental injury to the operator during use. For example, in a narrow space or an environment where multiple people are collaborating, the protruding crank may touch the human body, causing bruises and affecting construction safety. Summary of the Invention

[0003] In order to enable the crank handle to be stored when the wire reel is not in use, the present application provides a hidden crank handle structure for the wire reel. The structure opens a storage groove on the wire reel and enables the connecting assembly to rotate on the wire reel, so that the crank handle and the connecting assembly can be stored in the storage groove on the wire reel when not in use, so that the crank handle and the connecting assembly are not exposed to the outside for a long time. This is not only beneficial for staff to operate in a small space, but also reduces the risk of the crank handle and the connecting assembly being damaged or corroded, thereby extending the service life of the crank handle.

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] The embodiment of the present application discloses a hidden crank structure for a cable reel.

[0031] Reference Figures 1 to 3 The hidden handle structure of the cable reel includes a cable reel 1, a connecting component 2 and a handle 3.

[0032] The cable drum 1 in this embodiment is a small cable drum, and therefore, the cable drum 1 is made of plastic. An outer wall of the cable drum 1 is provided with a receiving groove 11 for receiving the connecting assembly 2 and the crank 3.

[0033] Reference Figure 4One end of the connecting assembly 2 is rotatably connected to the wire drum 1, and the connecting assembly 2 is used to drive the wire drum 1 to rotate. The connecting assembly 2 includes a fixed body 21, a rotating shaft 22, and a rotating body 23. The fixed body 21, the rotating shaft 22, and the rotating body 23 are all made of plastic and can be integrally formed.

[0034] Reference Figure 3 and Figure 4 There are two rotating shafts 22, which are symmetrically distributed on both sides of the fixed body 21. The fixed body 21 is rotatably connected to the wire drum 1 through the two rotating shafts 22. Specifically, the wire drum 1 is provided with a rotating groove 12 for accommodating the rotating shaft 22, and the rotating shaft 22 is located in the rotating groove 12. In order to facilitate the processing of the rotating groove 12, a process groove 13 is provided on the wire drum 1.

[0035] The rotating body 23 is located on an end of the fixed body 21 away from the wire drum 1 . When in use, the rotating body 23 rotates together with the fixed body 21 .

[0036] Reference Figure 3 and Figure 4 The crank handle 3 is rotatably connected to the connecting component 2. Specifically, the crank handle 3 is sleeved on the rotating body 23, and the crank handle 3 can rotate relative to the rotating body 23 to realize the rotational connection between the crank handle 3 and the rotating body 23 when it is necessary to drive the wire drum 1 to rotate.

[0037] When the cable reel 1 does not need to be rotated, the crank 3 and the connecting component 2 can be stored together in the storage groove 11 on the cable reel 1; when the cable reel 1 needs to be rotated, the staff will take out the crank 3 and the connecting component 2 together, and then drive the connecting component 2 to rotate by turning the crank 3, and the connecting component 2 then drives the cable reel 1 to rotate, so as to realize the retraction and release of the cable.

[0038] Reference Figure 3 In order to facilitate the staff to take out the crank handle 3 and the connecting component 2 from the storage groove 11, a clearance groove 14 is also provided on the cable drum 1. The clearance groove 14 is connected to the end of the storage groove 11 away from the rotating groove 12. When in use, the clearance groove 14 can make it easier for the staff to take out the crank handle 3 and the connecting component 2 from the storage groove 11.

[0039] Reference Figures 3 to 5When the crank handle 3 and the connecting component 2 are received in the receiving groove 11, in order to prevent the crank handle 3 and the connecting component 2 from falling out of the receiving groove 11, and when the crank handle 3 and the connecting component 2 drive the wire drum 1 to rotate, in order to prevent the connecting component 2 and the wire drum 1 from rotating relative to each other, thereby affecting the rotation of the wire drum 1, an elastic limiting plate 15 is formed on the wire drum 1, and the elastic limiting plate 15 can be integrally formed with the wire drum 1. The elastic limiting plate 15 is located below the fixed body 21, and the fixed body 21 abuts against the elastic limiting plate 15, and the bottom of the fixed body 21 is a lower abutting surface 211, and the side end of the fixed body 21 is a side abutting surface 212. The lower abutting surface 211 and the side abutting surface 212 are both flat surfaces, and the connection between the lower abutting surface 211 and the side abutting surface 212 can be set to a yielding inclined surface 213 for easy rotation. When in use, by rotating the connecting component 2, the lower abutting surface 211 or the side abutting surface 212 and the yielding inclined surface 213 will squeeze the elastic limiting plate 15, and the elastic limiting plate 15 will be deformed. When the side abutting surface 212 or the lower abutting surface 211 is completely in contact with the elastic limiting plate 15, the elastic limiting plate 15 will restore its shape, and then the side abutting surface 212 or the lower abutting surface 211 will abut against the elastic limiting plate 15.

[0040] By setting an elastic limiting plate 15, when the handle 3 and the connecting component 2 are stored in the storage groove 11 or in use, the connecting component 2 will not easily rotate with the wire drum 1, so that the handle 3 and the connecting component 2 can be stably stored in the storage groove 11 or used by the staff to drive the wire drum 1 to rotate.

[0041] Reference Figure 4 Since both the fixed body 21 and the rotating body 23 are made of plastic, they are susceptible to deformation. Therefore, fixed reinforcement ribs 214 are formed inside the fixed body 21, and rotation reinforcement ribs 231 are formed inside the rotating body 23 to improve the stability and deformation resistance of the fixed body 21 and the rotating body 23. The fixed reinforcement ribs 214 and rotation reinforcement ribs 231 can be integrally formed with the fixed body 21, the rotating body 23, and the rotating shaft 22.

[0042] Reference Figure 6 To improve the stability of the handle 3 on the rotating body 23 during relative rotation and to reduce the risk of the handle 3 falling off the rotating body 23 during relative rotation, a slot 232 is defined on the end of the rotating body 23 away from the fixed body 21. A snap ring 233 is formed on the inner wall of the slot 232 of the rotating body 23. A buckle 31 is formed inside the handle 3, and a snap protrusion 32 is formed on the buckle 31. Both the buckle 31 and the snap protrusion 32 are made of elastic plastic.

[0043] When in use, the rocking handle 3 is pre-placed on the rotating body 23 so that the buckle 31 and the snap protrusion 32 enter the snap groove 232, and then the rocking handle 3 is pressed continuously. At this time, the snap protrusion 32 is gradually squeezed onto the snap ring 233 and deformed. As the pressing continues, the snap protrusion 32 gradually separates from the snap ring 233. At this time, the installation of the rocking handle 3 and the rotating body 23 is completed, and the snap protrusion 32 and the snap ring 233 form a snap connection. At this time, the rocking handle 3 is pulled backward. Due to the snap connection and limitation of the snap ring 233 on the snap protrusion 32, the rocking handle 3 cannot separate from the rotating body 23.

[0044] Reference Figure 4 In order to enable the staff to better grasp the crank handle 3, a plurality of anti-slip grooves 33 are provided on the outer wall of the crank handle 3, and the anti-slip grooves 33 are in the shape of strips, and the plurality of anti-slip grooves 33 are evenly distributed along the circumferential direction of the crank handle 3.

[0045] If the cable on the cable reel 1 needs to be reeled in or out, bend the crank 3 in the storage groove 11 and take it out until the crank 3 and the connecting component 2 are perpendicular to the cable reel 1, and the lower abutting surface 211 of the fixed body 21 is completely abutted against the elastic limit plate 15, then shake the crank 3, use the crank 3 to drive the connecting component 2 to rotate, and the connecting component 2 drives the cable reel 1 to rotate. At this time, the cable reel 1 reels and unwinds the cable. After use, if the cable no longer needs to be reeled in or out, bend the crank 3 and the connecting component 2, and re-store the crank 3 and the connecting component 2 in the storage groove 11 on the cable reel 1.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
