Description

Technical Field

[0001] The invention relates to a segmentally adjustable magnetic brake mechanism. Background Art

[0002] Fishing is an outdoor sport that allows people to get close to nature and cultivate their sentiments. It is increasingly popular among enthusiasts. Drum reels and water drop reels are commonly used by fishing enthusiasts. They have the advantages of accurate casting, fast line release, and compact size, and are deeply loved by fishing enthusiasts.

[0003] In order to prevent the line from being blown up during use, the drum reel and the water drop reel are both equipped with a magnetic brake mechanism. When the drum reel (water drop reel) casts the line, the spool rotates at high speed to cut the magnetic lines and generate electromagnetic brake force, thereby slowing down the rotation speed of the spool and effectively preventing the line from being blown up. When the fishing reel is suitable for different spools, the required magnetic brake force also has different requirements. When a shallow spool (micro-spool) is selected, due to the light weight of the cup body and small rotational inertia, only a small magnetic brake force is needed to control the rotation speed of the spool; when a deep spool (general-purpose spool) is selected, the cup body is relatively heavy and has a larger rotational inertia, so a larger magnetic brake force is required to control the rotation of the spool. However, the size of the magnetic brake force mainly depends on the magnetic strength, individual size and number of installed magnets used, as well as the distance between the magnets and the spool. Once the magnets are selected, the magnetic strength and individual size will not change. The only way to change the number of magnets is to install and remove the magnets by yourself, so as to change the size of the magnetic brake force, but the magnets of most fishing reels cannot be removed after installation, and the number of magnets cannot be changed. In order to solve the above problems, the drum wheels (drip wheels) currently on the market are all equipped with a knob outside the body to adjust the distance between the magnet block and the spool. The closer the distance between the magnet block and the spool or the larger the overlapping area between the magnet block and the spool, the greater the magnetic braking force, and vice versa. However, the adjustable range is relatively limited.

[0004] In summary, due to the limited adjustment range of the magnetic braking force, the applicability of the drum wheel (water drop wheel) is limited. For example, if the original is a deep line cup, the corresponding magnet block is a strong magnetic magnet. The size and number are relatively large and large, and the magnetic braking force is also large. If you want to replace it with a shallow line cup, it will not be suitable because the magnetic braking force is too large; on the contrary, if the original is a shallow line cup, the magnetism, size, and number of the corresponding magnet blocks are relatively weak and small, and the magnetic braking force is also small. If you want to replace it with a deep line cup, it will not be suitable because the magnetic braking force is too small. Increasing or reducing the number of magnet blocks will alleviate this situation to a certain extent, but it is necessary to open the cover and remove the internal components. The operation is relatively cumbersome, and there is a risk of the magnet blocks being easily damaged and lost. Therefore, there is an urgent need for a segmented adjustable magnetic brake mechanism that can expand the adjustment range and enable it to be suitable for deep line cups and shallow line cups in different ranges.

[0035] In the above structure, a first positioning hole 23 is provided on the right side wall of the side cover 1 near the bottom end, a first ball 24 and a first positioning spring 25 are provided in the first positioning hole 23, and two first positioning grooves 26 corresponding to the first ball 24 are provided on the left side wall of the locking ring 9 near the bottom end.

[0036] In the above structure, a second hollow sleeve 27 is provided on the left side wall of the bearing seat 2 near the top end, and a return spring 28 is provided between the second hollow sleeve 27 and the magnetic adjustment rod 17 .

[0037] In the above structure, two symmetrically arranged straight grooves 29 are provided on the right end surface of the first hollow sleeve 10 , and convex ribs 30 matching the straight grooves 29 are provided on the inner wall of the top ring 13 .

[0040] In the above structure, an O-ring 37 is provided between the second screw 18 and the connecting rod, and the friction force of the rubber O-ring is used to generate a damping feeling when the magnetic knob 11 rotates.

[0041] In the above structure, a spiral groove 38 is provided on the circumferential outer wall of the magnetic force adjustment rod 17 , and a cylinder 39 inserted into the spiral groove 38 is provided at the top end of the second square column 20 .

[0042] The segmented adjustable magnetic brake mechanism of the present invention is used in a specific manner, such as Figure 6 As shown, the bearing seat is assembled on the drum wheel 40 together with the side cover. The bearing seat is locked on the side cover by three first screws, and all parts are axially fixed. The connecting rod of the magnetic adjustment knob is inserted from the outside of the side cover, and passes through the side cover, the top ring, the magnetic adjustment rod and the bearing seat in sequence. Then the connecting rod is locked on the right side of the bearing seat with a second screw. After locking, the magnetic adjustment knob can be rotated but cannot move left and right. A first hollow sleeve is provided at the top end of the right side of the side cover, and the top ring is sleeved on the first hollow sleeve. The first hollow sleeve is provided with a straight groove, and the inner hole of the top ring is provided with a convex rib matching therewith. The convex rib is stuck in the straight groove, so that the top ring can move left and right along the first hollow sleeve but cannot rotate. The toggle button is sleeved between the top ring and the side cover. When the toggle button rotates, its two first sloped surfaces will push the two second sloped surfaces of the top ring, and the top ring will move to the right along the first hollow sleeve of the left cover; when the toggle button rotates in the opposite direction, the top ring will fall back to the inner hole of the toggle button along the first sloped surface under the action of the reset spring. The toggle button is rotated within the angle between the two second positioning grooves through the second ball. As mentioned above, under the action of the first sloped surface and the second sloped surface, there will be two positions of the distance between the top ring and the toggle button. One is that the first sloped surface is in close contact with the second sloped surface, and the other is that the left end face of the top ring is on the rightmost end face of the toggle button. When the top ring is in different positions, the magnetic adjustment rod will also drive the magnet seat to different positions. The magnetic braking force provided by the magnetic brake mechanism will be significantly different, which provides the magnetic brake structure with two braking force ranges. When the top ring moves to the right, it will push the magnetic adjustment rod to the right together. At the same time, the spiral groove on the magnetic adjustment rod will push the cylinder and drive the entire magnet seat to move. When the toggle button is reversed and returned, the reset spring pushes the magnetic adjustment rod and then pushes the top ring back. The connecting rod of the magnetic adjustment knob is provided with a D-shaped flat cylinder (formed by a plane groove), and the magnetic adjustment rod is correspondingly provided with a matching limiting hole (D-shaped flat circular hole). In this way, when the connecting rod is inserted into the limiting hole: when the magnetic adjustment knob is turned, the magnetic adjustment rod will be driven to rotate synchronously.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
