Description

Technical Field

[0001] This utility model relates to the field of electric fishing reels, and in particular to an anti-jamming structure for the spool of an electric fishing reel. Background Technology

[0002] We know that existing electric fishing reels include a main support, an upper end cover, a lower end cover, a main shaft, a rocker arm, a spool shaft, a spool, a clutch gear, a planetary reducer, and a motor. The upper and lower end covers are located above the upper frame and below the lower frame of the main support, respectively. The main shaft is mounted on the main support and the upper end cover via bearings. The rocker arm is mounted on the main shaft above the upper end cover. The spool shaft is mounted on the main support on one side of the main shaft via bearings. The spool is mounted on the spool shaft with free rotation via bearings. A spool cover is provided on the upper end of the spool. The planetary support of the planetary reducer is mounted on the spool cover via bearings in the middle. The sun gear of the planetary reducer is fixed to the upper part of the spool shaft. The internal gear ring of the planetary reducer is mounted on the upper end of the spool. The planetary gears on the planetary support mesh with the internal gear ring. The planetary support of the planetary reducer... A clutch connector is located in the center of the upper side of the frame, above the spool cover, and has a clutch protrusion. The clutch gear is mounted on the planetary reducer via bearings, and its lower end has a clutch slot that engages with the clutch protrusion. A main gear meshes with the clutch gear on the main shaft, and a friction plate and a locking handle are located on the main shaft above the main gear. Rotating the locking handle controls the friction between the friction plate and the main gear, allowing the main gear and main shaft to be locked or unlocked. A clutch switch that engages with the clutch gear is located on the upper cover, controlling the up-and-down sliding of the clutch gear, which in turn controls the opening and closing of the clutch protrusion and the clutch slot. The motor is located on one side of the main support, and its output shaft is connected to the lower end of the spool shaft via gear transmission. During use, when reeling in the line, the clutch gear slides down, the clutch slot engages with the clutch protrusion, and the handle on the rocker arm is turned. The main shaft drives the main gear to rotate, which in turn drives the clutch gear and the planetary carrier of the planetary reducer to rotate. The planetary gear drives the internal gear ring and the spool to rotate, completing manual reeling. For electric reeling, based on manual reeling, turning the locking handle controls the friction plate to lock the main gear and main shaft. At this time, the planetary carrier is locked, the motor works, and drives the spool shaft to rotate through the gear transmission system. The sun gear on the spool shaft rotates, which drives the internal gear ring and the spool to rotate, completing electric reeling. When letting out the line, the clutch slot separates from the clutch protrusion, and the spool can rotate freely to let out the line.

[0003] In existing electric fishing reels, when the electric pulling force is too high, the clutch slot at the lower end of the clutch gear and the clutch protrusion on the clutch connecting seat are prone to deformation. With prolonged use, excessively deformed clutch slots or protrusions can interfere with adjacent components, causing jamming or ineffective engagement, resulting in slippage and malfunction. During reeling in, the fishing line brings seawater onto the electric fishing reel. Seawater enters the reel through the gap between the spool and the main support, especially into the bearings, causing rust and resulting in jamming or even complete malfunction of the spool. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a spool anti-jamming structure for an electric fishing reel where the mating part of the clutch gear and clutch connecting seat is not easily deformed and is not likely to interfere with adjacent parts or become unusable after deformation.

[0005] Another objective of this invention is to provide an anti-jamming structure for the spool of an electric fishing reel, which prevents seawater from easily entering the reel, prevents the bearings from rusting due to water ingress, and prevents jamming.

[0006] The technical solution adopted by this utility model to overcome the shortcomings of the prior art is:

[0007] An anti-jamming structure for the spool of an electric fishing reel is disclosed. The electric fishing reel includes a main support, an upper end cover, a lower end cover, a spool shaft, a spool, a clutch gear, and a planetary reducer. The upper and lower end covers are located above the upper frame and below the lower frame of the main support, respectively. The spool shaft is mounted inside the main support via bearings. The spool is rotatably mounted on the spool shaft via bearings. A spool cover is located on the upper end of the spool. The planetary support of the planetary reducer is mounted on the spool cover via bearings in the middle. The sun gear of the planetary reducer is fixedly mounted on the upper part of the spool shaft. The internal gear ring of the planetary reducer is installed on the upper end of the spool. A clutch connecting seat is provided in the center of the upper side of the planetary support, and the clutch connecting seat is located above the spool cover. The clutch gear is mounted on the planetary reducer and can slide up and down via a bearing. The clutch connecting seat is cylindrical and has a clutch locking pin. The lower end of the clutch gear has a clutch locking sleeve. The clutch locking sleeve has four locking grooves evenly distributed around its circumference to engage with the clutch locking pin. A protective sleeve is fitted on the outer side of the clutch locking sleeve.

[0008] The electric fishing reel described in this utility model also includes a main shaft, a rocker arm, and a motor. The main shaft is mounted on a main bracket and an upper cover on one side of the spool shaft via bearings. The rocker arm is mounted on the main shaft above the upper cover. The main shaft is provided with a main gear that meshes with a clutch gear. The main shaft above the main gear is provided with a friction plate and a locking handle. The upper cover is provided with a clutch switch that cooperates with the clutch gear. The motor is located on one side of the main bracket, and the output shaft of the motor is connected to the lower end of the spool shaft via gear transmission.

[0009] Furthermore, the upper end of the spool is provided with an installation sleeve, the outer diameter of which is smaller than the outer diameter of the upper end of the spool. The spool cover is fixedly installed on the upper end of the installation sleeve by screws. A first baffle plate is provided on the outer side of the installation sleeve, the outer diameter of which is not greater than the outer diameter of the upper end of the spool.

[0010] Furthermore, the outer diameter of the spool cover is larger than the outer diameter of the mounting sleeve. The spool cover located outside the mounting sleeve forms a second water baffle, which can prevent water from entering.

[0011] Furthermore, the upper frame of the main support above the spool cover is provided with an annular connecting plate on its inner side. An annular mounting seat extending downwards is provided on the inner side of the connecting plate. A positioning connecting seat is provided on the upper center of the spool cover, and the positioning connecting seat is mounted on the annular mounting seat via a bearing. A water-blocking ring is provided on the upper side of the spool cover outside the annular mounting seat. The upper end face of the water-blocking ring is higher than the lower end face of the annular mounting seat. A third water-blocking plate is provided on the outer side of the upper end of the water-blocking ring. An annular water-guiding groove is provided on the outer side of the annular mounting seat opposite to the third water-blocking plate. The annular mounting seat below the water-guiding groove forms a fourth water-blocking plate.

[0012] In this utility model, the lower end of the clutch gear is mounted on the inner side of the connecting frame plate via the lower bearing, the clutch snap sleeve is located at the lower end of the clutch gear inside the lower bearing, and the outer diameter of the protective sleeve is smaller than the inner diameter of the lower bearing.

[0013] In this utility model, the planetary reducer has a bracket mounting sleeve on the upper middle part of the planetary support. The bracket mounting sleeve is mounted on the inner side of the positioning connection seat of the cup cover via a bearing. The clutch connection seat is located at the upper middle part of the bracket mounting sleeve.

[0014] The internal gear ring of the planetary reducer described in this utility model is fixedly installed on the inner side of the mounting sleeve, and the lower end of the spool shaft is connected to the lower frame of the main support via a bearing. The upper and lower frames of the main support are fixedly connected by an intermediate connecting frame or connecting rod to form the main support.

[0015] In a further improvement, the clutch gear (clutch engagement sleeve) is made of high-hardness copper material.

[0016] In operation, two of the four engagement grooves on the clutch engagement sleeve engage with the clutch engagement pin at a time. Over extended use, this halves the actual working time of the engagement grooves and minimizes damage. The protective sleeve prevents outward deformation of the engagement grooves under stress, avoiding interference with adjacent components and preventing jamming. The clutch engagement sleeve, made of high-hardness copper, reduces friction when separating from the planetary support. The first, second, third, and fourth water-blocking plates allow incoming seawater to accumulate around them. When the electric fishing reel is reeled in, the seawater is flung out as the spool rotates, preventing seawater corrosion of the bearings and reducing the likelihood of jamming during spool rotation.

[0023] like Figures 1-6The electric fishing reel shown has a spool anti-jamming structure. The reel includes a main support, an upper cover 2, a lower cover 16, a main shaft, a rocker arm, a spool shaft 13, a spool 12, a clutch gear 7, a planetary reducer, and a motor. The upper cover 2 and lower cover 16 are located above the upper frame 1 and below the lower frame 15 of the main support, respectively. The main shaft is mounted on the main support and the upper cover via bearings. The rocker arm is mounted on the main shaft above the upper cover 2. The main shaft has a main gear that meshes with the clutch gear, and a... It has friction plates and a locking handle. The upper cover 2 has a clutch switch that engages with the clutch gear. The motor is located on one side of the main support, and its output shaft is connected to the lower end of the spool shaft 13 via gear transmission. The spool shaft 13 is mounted on the main support on one side of the main shaft via bearings. The spool 12 is mounted on the spool shaft 13, which is rotatably mounted via bearings. The upper end of the spool 12 has a spool cover 10. The clutch gear 7 is mounted above the planetary reducer, which can slide up and down via bearings. The above structure is the same as existing technology and will not be described again. The upper end of the spool 12 has a mounting sleeve 12b, the outer diameter of which is smaller than the outer diameter of the upper end of the spool. The spool cover 10 is fixed to the upper end of the mounting sleeve 12b with screws. The outer side of the mounting sleeve 12b has a first annular baffle 12a, the outer diameter of which is not greater than the outer diameter of the upper end of the spool. The planetary support 6a of the planetary reducer is mounted in the middle of the line cup cover 10 via a bearing. The sun gear 6d of the planetary reducer is fixedly mounted on the upper part of the line cup shaft 13. The internal gear ring 6c of the planetary reducer is mounted inside the mounting sleeve 12b at the upper end of the line cup. A clutch connecting seat 6 is provided in the center of the upper side of the planetary support 6a, and the clutch connecting seat 6 is located above the line cup cover 10. The clutch connecting seat 6 is cylindrical and has cylindrical clutch locking pins 3 protruding to the left and right. The clutch gear 7 has a clutch engagement sleeve 7f at its lower end. The clutch gear 7 and the clutch engagement sleeve 7f are integrally formed. The clutch engagement sleeve 7f has four engagement grooves 7b evenly distributed circumferentially to mate with the clutch engagement pin 3. The bottom surface of the engagement groove 7b is an arc shape that mates with the cylindrical clutch engagement pin 3. Each engagement groove has an inclined guide slope 7c on one side of the lower end face of the clutch engagement sleeve. The guide slope 7c guides the clutch engagement pin 3, making it easier for it to smoothly enter the engagement groove. A protective sleeve 4 is fitted on the outside of the clutch engagement sleeve 7f, and the protective sleeve is interference-fitted with the clutch engagement sleeve.

[0024] This embodiment is further improved by having an outer diameter larger than that of the mounting sleeve 12b; this prevents water from entering, and the outer edge 10a of the spool cover 10 acts as a second water baffle. An annular connecting plate 1a is provided on the inner side of the upper frame 1 of the main support above the spool cover 10. An annular mounting seat 1b extending downwards is provided on the inner side of the connecting plate 1a; the two are integrally formed. A sleeve-shaped positioning connecting seat 10d is provided on the upper middle part of the spool cover 10, and the positioning connecting seat 10d is mounted on the inner side of the annular mounting seat 1b via a bearing 9. A water-blocking ring 10b is provided on the upper side of the spool cover 10 outside the annular mounting seat 1b, with the upper end face of the water-blocking ring 10b higher than the lower end face of the annular mounting seat 1b. An annular third water baffle 10c is provided on the outer side of the upper end of the water-blocking ring 10b. An annular water guide groove 1c is provided on the outer side of the annular mounting seat 1b opposite to the third water baffle 10c. The annular mounting seat below the water guide groove 1c forms a fourth water baffle. The clutch gear 7 is mounted on the upper end of the upper end cover 2 via an upper bearing 8. The lower end of the clutch gear 7 has a bearing mounting seat 7d, which is mounted on a bearing seat inside the connecting frame plate 1a via a lower bearing 5. The clutch engagement sleeve 7f is located at the lower end of the bearing mounting seat 7d inside the lower bearing 5. The outer diameter of the protective sleeve 4 is smaller than the outer diameter of the bearing mounting seat 7d to prevent interference between the protective sleeve 4 and the lower bearing 5. The planetary support 6a of the planetary reducer has a support mounting sleeve 6b at its upper center. The support mounting sleeve 6b is mounted on the inner side of the positioning connecting seat 10d of the spool cover via a bearing 11. The clutch connecting seat 6 is located at the upper center of the support mounting sleeve. The upper end of the spool shaft is mounted inside the support mounting sleeve 6b via a bearing to improve overall stability. The clutch engagement sleeve (clutch gear) is made of high-hardness copper material.

[0025] In operation, two of the four engagement grooves on the clutch engagement sleeve engage with the clutch engagement pin at a time. Over extended use, this halves the actual working time of the engagement grooves and minimizes damage. The protective sleeve prevents outward deformation of the engagement grooves under stress, avoiding interference with adjacent components and preventing jamming. (The clutch engagement sleeve, made of high-hardness copper, reduces friction when separating from the planetary support). The first, second, third, and fourth water-blocking plates allow incoming seawater to accumulate around them. When the electric fishing reel is reeled in, the seawater is flung out as the spool rotates, preventing seawater corrosion of the bearings and reducing the likelihood of jamming during spool rotation.
