[0017] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative effort should all fall within the protection scope of this utility model.

[0018] like Figure 1 The present invention provides a detachable drum frame body 100, located between the main cover 200 and the side cover 300, wherein the frame body 100 has a space in the middle for accommodating a spool 400. Figure 2 As shown, the frame body 100 includes an upper sealing plate 2, a lower sealing plate 3, and a plurality of connecting posts 1 located between the upper sealing plate 2 and the lower sealing plate 3. The upper sealing plate 2 and the lower sealing plate 3 are provided with connecting holes 201 corresponding to the positions of each connecting post 1. The connecting post 1 is detachably connected to the connecting hole 201 via a fixing cap 4. The connecting post 1 is provided with a first limiting part that restricts the inward movement of the upper sealing plate 2 and the lower sealing plate 3. The fixing cap 4 is provided with a second limiting part that restricts the outward movement of the upper sealing plate 2 and the lower sealing plate 3. The end of the fixing cap 4 away from the connecting post 1 has a first internal thread 401 for connecting bolts. The inward movement of the upper sealing plate 2 and the lower sealing plate 3 refers to the upper sealing plate 2 and the lower sealing plate 3 moving towards the inside of the frame body 100 in a direction that brings them closer to each other. The outward movement of the upper sealing plate 2 and the lower sealing plate 3 refers to the upper sealing plate 2 and the lower sealing plate 3 moving towards the outside of the frame body 100 in a direction that moves them away from each other.

[0019] Specifically, in Example 1, such as Figure 7 As shown, the end of the connecting column 1 has a first small-diameter variable shaft 101. One end of the first small-diameter variable shaft 101, passing through the connecting hole 201, is formed with a first external thread 102. The fixing cap 4 is threadedly engaged with the first external thread 102 via a second internal thread 402. The outer ring surface of the first small-diameter variable shaft 101 is the first limiting part, and the outer ring surface of the second internal thread 402 is the second limiting part. The second internal thread 402 of the fixing cap 4 is threadedly engaged with the first external thread 102 at the end of the connecting column 1, completing the detachable connection between the two. The first small-diameter variable shaft 101 serves as a through shaft end that matches the size of the connecting hole 201, allowing the upper sealing plate 2 or lower sealing plate 3 to be clamped and fixed to the outside of the first small-diameter variable shaft 101 by the fixing cap 4, thus ensuring the structural stability and strength of the entire frame body 100. In embodiment 2, as... Figure 8As shown, the end of the connecting post 1 has a third internal thread 103. The end of the fixing cap 4 connected to the connecting post 1 has a second small-diameter reducing shaft 404. The end of the second small-diameter reducing shaft 404 passing through the connecting hole 201 has a second external thread 405. The second external thread 405 is threadedly engaged with the third internal thread 103. The outer ring surface of the third internal thread 103 is the first limiting part, and the outer ring surface of the second small-diameter reducing shaft 404 is the second limiting part. At this time, the second small-diameter reducing shaft 404 of the fixing cap 4 serves as a through shaft end that fits the size of the connecting hole 201. With the cooperation of the second external thread 405 of the fixing cap 4 and the third internal thread 103 of the connecting post 1, the upper sealing plate 2 or the lower sealing plate 3 is clamped. The connection is fixed between the connecting post 1 and the fixing cap 4. Of course, in other embodiments, multiple sets of connecting parts formed by one connecting post 1 and two fixing caps 4 can adopt the above-mentioned connection combinations with different structures. That is, one connecting post 1 is provided with a third internal thread 103 at both ends, and the fixing cap 4 that cooperates with it is provided with a second small-diameter variable shaft 404 and a second external thread 405. The other connecting post 1 is provided with a first small-diameter variable shaft 101 and a first external thread 102 at both ends, and the fixing cap 4 that cooperates with it is provided with a second internal thread 402. Alternatively, one end of one connecting post 1 can be provided with a third internal thread 103, and the other end can be provided with a first small-diameter variable shaft 101 and a first external thread 102, and the structure of the fixing cap 4 that cooperates with it can be adjusted accordingly.

[0020] To facilitate applying force to the aforementioned fixing cap 4 with a wrench, and to complete the tightening and loosening operations, such as Figure 7 and Figure 8 As shown, the outer side of the fixing cap 4 is provided with at least two wrench grooves 403. Preferably, the wrench grooves 403 are provided at the end away from the first internal thread portion 401.

[0021] Compared to the existing riveting method for connecting columns 1, the connecting column 1 is detachably connected to the fixing cap 4, and the upper sealing plate 2 and lower sealing plate 3 are clamped and fixed between the fixing cap 4 and the connecting column 1, thus completing the detachable connection structure of the entire frame body 100. When any connecting column 1 is damaged, the fixing cap 4 on each connecting column 1 can be removed, the frame body 100 can be separated, and the corresponding connecting column 1 can be replaced. Compared with the existing operation of replacing the entire frame body 100, the maintenance cost is effectively reduced.

[0022] Further preferred, such as Figure 6As shown, there are three connecting posts 1, namely a first connecting post 1, a second connecting post 1, and a third connecting post 1. A line guide 500 is provided between the first connecting post 1 and the second connecting post 1, and a support post 6 is provided between the first connecting post 1 and the second connecting post 1. The line guide 500 and the support post 6 are detachably installed between the upper sealing plate 2 and the lower sealing plate 3. Specifically, the line guide 500 is existing technology in the field of fishing reel technology, and its assembly method is the same as that in existing technology. One end of it uses a flat shaft as a transmission end to cooperate with the flat hole 203 on the upper sealing plate 2, and the other end uses a round shaft as a pivot end to cooperate with the round hole 202 on the lower sealing plate 3. Figure 4 As shown, the outer wall of the second connecting column 1 is provided with a sliding groove 104 that slides in conjunction with the end of the wire gauge 501 of the cable guide 500; while both ends of the support column 6 are formed with small-sized variable-diameter shafts identical to those of the connecting column 1 in Embodiment 1. The upper sealing plate 2 and the lower sealing plate 3 are provided with round holes 202 that mate with the small-sized variable-diameter shafts. The upper sealing plate 2 and the lower sealing plate 3 clamp and fix the support shaft between them, as shown. Figure 3 As shown, the support column 6 and the first connecting column 1 are fixed with foot plates 5 that cooperate with the wheel seat. Specifically, the foot plates 5 are fixed to the first connecting column 1 and the support column 6 by two rivets 9, which serve as intermediate parts for the connection and cooperation between the drum and the wheel seat.

[0023] More preferably, the triangle formed by the center line connecting two adjacent connecting columns 1 is an equilateral triangle, thereby ensuring that the formed frame body 100 has optimal structural strength.

[0024] like Figure 6 As shown, the second connecting post 1 is provided with an acupressure plate 7. One end of the acupressure plate 7 is provided with a hook portion 701. The hook portion 701 has a snap-fit ​​groove that engages with the second connecting post 1. The acupressure plate 7 is provided with positioning grooves 702 on both sides. The upper sealing plate 2 and the lower sealing plate 3 are provided with positioning protrusions 204 that engage with the positioning grooves 702. Alternatively, the acupressure plate 7 is provided with positioning protrusions 204 on both sides, and the upper sealing plate 2 and the lower sealing plate 3 are provided with positioning grooves 702 that engage with the positioning protrusions 204, so as to fix the acupressure plate 7 on the frame body 100. The surface of the acupressure plate 7 forms an acupressure surface, which is parallel to the plane where the foot plate 5 is located, and serves as the pressing surface for the thumb when the fishing operator controls the cup.

[0025] like Figure 5As shown, the third connecting post 1 is provided with a clutch plate 8. The clutch plate 8 has a through hole 802 in the middle that rotatably engages with the third connecting post 1. The end of the clutch plate 8 away from the foot plate 5 is formed with a push plate part 801. The end of the clutch plate 8 near the foot plate 5 is provided with a push shaft 803 that engages with the clutch transmission assembly 600 in the upper cover. When the fishing operator pushes the push plate part 801, the clutch plate 8 rotates around the third connecting post 1. The push shaft 803 pushes the clutch disc 601 of the clutch transmission assembly 600 to rotate, thereby engaging the clutch pawl on the clutch transmission assembly 600 with the pawl on the rocker arm transmission shaft. Then, the rotation of the rocker arm separates the two, completing the clutch operation during casting. Specifically, the clutch transmission assembly 600 has the same structure as in the prior art. Its specific structure can be referred to in the clutch transmission assembly 600 in our company's publication number CN207083920U. In this solution, as Figure 5 As shown, the clutch disc 601 has a push rod 602 extending from its end, which slides in contact with the push shaft 803. To limit the starting and ending positions of the push shaft 803, an arc-shaped groove 205 is provided on the upper sealing plate 2. The push shaft 803 passes through the arc-shaped groove 205 and slides in contact with the push rod 602 along the moving path provided by the arc-shaped groove 205. When the push rod 602 moves from the starting position to the ending position, it moves to the left, causing the clutch disc 601 to rotate clockwise. The clutch teeth engage with the ratchet, and the rocker arm is rotated to separate the clutch teeth from the ratchet, causing the clutch disc 601 to rotate counterclockwise. The push rod 602 moves to the right, causing the push shaft 803 to return to the starting position. At this time, the clutch plate 8 is reset.

[0026] Taking Example 1 as an example, the frame body 100 is assembled by connecting the side cover 300 to the lower sealing plate 3 and threading the bolts to the fixing caps 4 at the lower sealing plate 3. The spool 400 is placed inside the frame body 100 and engages with the gear at the pivot end of the cable guide 500. The main cover 200 is connected to the upper sealing plate 2 and threadedly engaged with the fixing caps 4 at the upper sealing plate 2 by bolts. This completes the assembly of the entire drum. When repairing the main cover 200, the spool 400, or the parts inside the side cover 300, the repair method is the same as in the prior art. When repairing each connecting post 1 on the frame body 100, the fixing caps 4 on each connecting post 1 are removed, the upper sealing plate 2 / lower sealing plate 3 is removed, and the corresponding connecting post 1 is replaced. There is no need to replace or scrap the entire frame body 100, thus reducing the product's repair cost.
