Detailed Description
The following description of the embodiments of the present invention will clearly and fully describe the technical aspects of the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
As shown in fig. 1, the spool device convenient to maintain comprises a mandrel 1, a sector plate 2, a pin shaft 3 arranged between the mandrel 1 and the sector plate 2, an elastic piece 4, a cover plate 5, a first sleeve 6 and a second sleeve 7.
Wherein, cavity 201 has been seted up in the sector plate 2, and the one side of cavity 201 keeping away from dabber 1 runs through sector plate 2's sector outer wall. Because the cavity 201 is communicated with the sector of the sector plate 2, a user can detach and install the pin shaft 3 from the cavity 201 without detaching the sector plate 2 from the wedge.
One end of a pin shaft 3 is arranged on the peripheral wall of the mandrel 1, and the other end of the pin shaft 3 penetrates through the sector plate 2 along the radial direction of the mandrel 1 and is inserted into the cavity 201. The inner end of the pin shaft 3 is usually in interference fit or screwed connection, so that the pin shaft is fixedly connected with the mandrel 1.
One end of the elastic piece 4 is arranged at the end part of the pin shaft 3 inserted into the cavity 201, and the other end of the elastic piece 4 extends towards the mandrel 1 along the radial direction of the mandrel 1 and abuts against the inner wall of the cavity 201. The end part of the pin shaft 3, which is positioned in the cavity 201, is actually provided with a limiting plate, and the elastic piece 4 is arranged between the limiting plate and the bottom end surface of the cavity 201; under normal conditions, the wedge is matched with the sector plate 2, and the elastic piece 4 is compressed under pressure, so that the bottom end surface of the cavity 201 is pressed inwards, the sector plate 2 is abutted with the wedge, and the outer surface of the winding drum is kept circular and cannot be out of round; when the winding drum device is subjected to rigid winding, the wedge is pressed to retract the wedge to give way, so that one of the fan-shaped plates 2 is also retracted, the winding drum is reduced in diameter, and the condition of rigid winding is eliminated.
However, in practical assembly, in order to ensure the connection stability of the pin shaft 3 and the mandrel 1, the connection end of the pin shaft 3 and the mandrel 1 generally has a larger shaft diameter, so that after the pin shaft 3 is detached from the cavity 201, it is difficult to take out the pin shaft 3 from the cavity 201, and it is more difficult to replace the pin shaft 3. To solve this problem, the second embodiment of the present invention is realized by the following means.
As shown in fig. 1, in combination with fig. 2, the end surface of the fan-shaped plate 2 facing the mandrel 1 is provided with a window 202, the window 202 is communicated with the cavity 201, the first sleeve 6 is arranged in the window 202, one end of the first sleeve 6 extends towards the mandrel 1 and abuts against the peripheral wall of the mandrel 1, the other end of the first sleeve 6 extends towards the direction away from the mandrel 1 and is inserted into the cavity 201, and the pin shaft 3 is arranged in the first sleeve 6 in a penetrating manner. The window 202 enlarges the inner diameter of the cavity 201 on the side communicating with the outside, thereby enabling the pin 3 to be taken out from the cavity 201.

The second sleeve 7 is tightly matched in the cavity 201, so that the structure of the sector plate 2 is reinforced; while abutting against the bottom end face of the cavity 201 by the step 71 of the second sleeve 7; the pin shaft 3 is arranged in the first sleeve 6 and the second sleeve 7 in a penetrating manner, so that the problems of small pressure area, uneven pressure and the like of the elastic piece 4 can be avoided, and meanwhile, after the first sleeve 6 and the second sleeve 7 are taken out of the cavity 201, the window 202 can be exposed, and the disassembly and maintenance work of the pin shaft 3 can be facilitated for operators. Wherein, preferably, the inner diameter of the window 202 is larger than the shaft diameter of the pin shaft 3, and the inner diameter of the first sleeve 6 is the same as the shaft diameter of the pin shaft 3 and is not larger than the inner diameter of the second sleeve 7, so that the pin shaft 3 can be tightly penetrated in the first sleeve 6.
As an alternative embodiment, the cover plate 5 is disposed in the cavity 201 and is located at one side of the cavity 201 penetrating through the sector plate 2, and the outer wall of the cover plate 5 away from the mandrel 1 is flush with the outer wall of the sector plate 2, so as to cover the outer opening of the cavity 201, and avoid the problem of out-of-round of the outer wall of the winding drum device.
The current reel device needs to ensure that the extending direction of the pin shaft 3 is the same as the radial direction of the mandrel 1, and when the reel device is adopted, a large gap is reserved between the pin shaft 3 and the window 202, so that the inserting angle of the pin shaft 3 is difficult to position when the pin shaft 3 is detached and installed, the pin shaft 3 is not aligned with the mounting hole on the mandrel 1, the mounting position of the pin shaft 3 is offset, and the damage rate of the pin shaft 3 is greatly improved.
