Description

Technical Field

[0001] This utility model relates to the field of fishing tackle technology, specifically to a fishing rod section retraction and discharge control device. Background Technology

[0002] A fishing rod is a fishing tool, which is a long, thin, multi-section rod-shaped object. It usually has a cylindrical handle section, which gradually tapers to a point towards the tip. It is used with a fishing line connected to a baited hook.

[0003] Existing telescopic fishing rods typically require manual retraction and extension. For long rods (such as cannon rods over 12 meters in length), manual retraction and extension are often time-consuming, laborious, and cumbersome. Furthermore, hands are easily stained with black residue from the internal carbon cloth during retraction and extension, causing significant inconvenience to users and failing to adequately meet their needs.

[0004] Utility model patent No. 202421988120.2 discloses an electric telescopic adjustment structure for a fishing rod, including a first fixed plate, two second fixed plates integrally formed at the front ends of the first fixed plate, and third fixed plates integrally formed at the front ends of the inner sides of the second fixed plates. A side groove is formed between the two third fixed plates. The rear sides of the two third fixed plates are rotatably connected to the front sides of the first fixed plate via bearings, and a first rotating shaft and a second rotating shaft are rotatably connected. A driven drive wheel is fixedly installed on the outer side of the first rotating shaft, and a driven drive wheel is fixedly installed on the outer side of the second rotating shaft. A motor is fixedly installed on the rear side of the first fixed plate, and the output shaft of the motor is fixedly connected to the rear end of the second rotating shaft. This utility model starts with a control switch and controls the forward and reverse rotation of the motor, thereby driving the driven drive wheel to rotate in both directions, which in turn drives the telescopic cylinder at the front end of the fishing rod to rotate outward to extend or inward to shorten, allowing for automatic extension or retraction of the fishing rod. However, this prior art patent still has the following technical defects: 1. It is inconvenient to open and close the fishing rod, and it is not convenient to elastically open and close and clamp the fishing rod as its thickness changes during the fishing rod's extension and retraction process; 2. A single motor drives the active drive wheel, while the driven wheel is passively driven. The rotational drive is not stable enough and cannot effectively and stably drive the extension and retraction of the fishing rod. 3. It is not convenient to fix the adjustment device on the outside of the handle joint, and it relies entirely on manual hand operation, which is not convenient. Utility Model Content

[0005] To overcome the technical deficiencies in the prior art and effectively solve the technical problems in the background art, this utility model provides the following technical solution: A control device for retracting and extending a fishing rod section includes a reel frame. The reel frame consists of two symmetrical, openable U-shaped structures. Each of the two reel frames has a drive wheel in its U-shaped groove for retracting and extending the rod head that holds the main body of the pull-out fishing rod. The two reel frames are respectively provided with a drive mechanism on the same side outside the U-shaped groove. The side extensions of the two reel frames on the same side are hinged by an elastic clamping structure.

[0006] As a preferred technical solution of this utility model, the elastic clamping structure includes a rotating disk, a torsion spring, a tension rod, and a connecting hole. The rotating disk is integrally disposed on the rear side of the wheel frame. The two rotating disks on the two wheel frames are rotatably connected by a rotating shaft. A torsion spring is disposed at one end of the rotating shaft. A tension rod is integrally disposed at both ends of the torsion spring. The two wheel frames are symmetrically provided with connecting holes on their sides. The outer ends of the two tension rods are respectively fastened and fixed to the corresponding connecting holes. The two tension rods and the torsion spring have an outward V-shaped structure.

[0007] As a preferred embodiment of the present invention, the drive mechanism includes a DC motor and a drive shaft. The drive shaft is rotatably connected between the two arms of the wheel frame. The drive wheel is located on the outside of the drive shaft. A DC motor with an output shaft fixedly connected to one end of the drive shaft is provided on one side of the wheel frame.

[0008] As a preferred technical solution of this utility model, it also includes a connecting component for connecting to the front end of the rod tube of the retractable fishing rod body. The connecting component includes a connecting rod, an arc-shaped plate, a first fixing strap, a Velcro A side, a second fixing strap, a Velcro B side, a fixing buckle, and a rubber pad. The connecting rod is integrally set at the rear end of one of the reel frames. The rear end of the connecting rod is integrally set with an arc-shaped plate that corresponds to and fits against the outer side of the rod tube. The upper and lower ends of the arc-shaped plate are respectively provided with a first fixing strap and a second fixing strap. The sides of the first fixing strap and the second fixing strap are respectively provided with Velcro A side and Velcro B side that can be correspondingly glued. The outer end of the second fixing strap is provided with a fixing buckle for the first fixing strap to pass through. The inner side of the arc-shaped plate is provided with a rubber pad.

[0009] As a preferred technical solution of this utility model, it also includes a power supply component for providing power to the drive mechanism. The power supply component includes a battery, a connecting wire, a plug, an elastic fixing strap, and a socket. The battery is detachably fixed to the front end of the outer side of the handle section by the elastic fixing strap. A handle is provided on the outer side of one of the wheel frames. A socket is provided at the rear end of the handle. A control switch corresponding to the battery and the DC motor is provided on the outer side of the handle. A connecting wire and a plug for connecting to the socket and the control switch are provided on the battery.

[0010] As a preferred technical solution of this utility model, the drive wheel is a roller structure that is thinner in the middle and thicker at both ends, with a rubber membrane containing a cavity on the outer side. A gap groove is formed between the two drive wheels for the rod tip to pass through and for the two drive wheels to elastically clamp the rod tip. The surface of the drive wheel is provided with a concave pattern.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The elastic clamping structure facilitates the opening and closing of the two U-shaped reel frames, and during the fishing rod's extension and retraction, it elastically opens, closes, and clamps as the fishing rod's thickness changes. 2. The extension and retraction of the fishing rod are driven by a drive mechanism; 3. The wheel frame and its components can be connected and fixed to the front end of the handlebar joint through the connecting components. The rubber pads provide cushioning and protection to prevent the curved plate from squeezing and abrading the outside of the handlebar joint. 4. Power is provided and control is performed via the power supply assembly and control switch; 5. The concave pattern on the rubber diaphragm surface of the drive wheel facilitates the collection and concealment of carbon powder that falls off due to rod section friction, ensuring that the friction of the drive wheel is not weakened by the presence of carbon powder, thereby guaranteeing the performance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-10 This utility model provides a technical solution: a fishing rod section retraction and discharge control device, including a wheel frame 1, which is two vertically symmetrical, openable U-shaped structures. The U-shaped grooves of the two wheel frames 1 are provided with drive wheels 10 for retracting and extending the rod head 81 of the fishing rod body 8. The two wheel frames 1 are respectively provided with drive mechanisms 3 on the same side outside the U-shaped groove. The side extensions of the two wheel frames 1 on the same side are hinged by an elastic clamping structure 2.

[0025] Furthermore, such as Figure 4 As shown, the elastic clamping structure 2 includes a rotating disk 21, a torsion spring 22, a tension rod 23, and a connecting hole 24. The rotating disk 21 is integrally mounted on the rear side of the wheel frame 1. The two rotating disks 21 on the two wheel frames 1 are rotatably connected by a rotating shaft. One end of the rotating shaft is fitted with a torsion spring 22, and both ends of the torsion spring 22 are integrally mounted with tension rods 23. The two wheel frames 1 have symmetrically opened connecting holes 24 on their sides. The outer ends of the two tension rods 23 are respectively fastened and fixed to the corresponding connecting holes 24. The two tension rods 23 and the torsion spring 22 have an outward V-shaped structure. In use, the rotating disk 21, torsion spring 22, tension rod 23, and connecting hole 24 work together to facilitate the rotation, opening, and closing of the two wheel frames 1. Furthermore, during the fishing rod's release and retraction, the structure elastically opens, closes, and clamps according to the change in the thickness of the fishing rod.

[0026] Furthermore, such as Figure 5As shown, the drive mechanism 3 includes a DC motor 31 and a drive shaft 32. The two arms of the wheel frame 1 are rotatably connected to the drive shaft 32 via bearings. A drive wheel 10, which is thinner in the middle and thicker at both ends, is bonded and fixed to the outside of the drive shaft 32. A rubber diaphragm is fitted and bonded to the outside of the drive wheel 10, and there is a cavity between the drive wheel 10 and the rubber diaphragm. The structural principle is a mature existing technology, and its structural principle will not be further described here. In addition, the surface of the rubber diaphragm of the drive wheel 10 is provided with concave patterns like car tires, which facilitates the collection and concealment of carbon powder that falls off due to the friction of the rod section, ensuring that the friction of the drive wheel 10 is not weakened by the presence of carbon powder. To ensure the effectiveness of the fishing rod, a gap groove 4 is formed between the two drive wheels 10, allowing the rod tip 81 to pass through and enabling the two drive wheels 10 to elastically clamp the rod tip 81. A DC motor 31 is fixedly installed on one side of the reel frame 1 by bolts and nuts. The output shaft of the DC motor 31 is fixedly connected to one end of the drive shaft 32 by bolts and nuts. In use, the rod tip 81 is pushed from back to front through the gap groove 4 (or the two reel frames 1 are manually opened and inserted, and then the torsion spring 22 clamps it after being released). Then, the two DC motors 31 drive the two drive shafts 32 and the drive wheels 10 to rotate in opposite directions, thereby driving the extension and retraction of the fishing rod.

[0027] Furthermore, such as Figure 6 , 7 As shown, it also includes a connecting assembly 5 for connecting to the front end of the rod barrel of the retractable fishing rod body 8. The connecting assembly 5 includes a connecting rod 51, an arc-shaped plate 52, a first fixing strap 53, a Velcro A side 54, a second fixing strap 55, a Velcro B side 56, a fixing buckle 57, and a rubber pad 58. The connecting rod 51 is integrally set at the rear end of one of the reel frames 1. The rear end of the connecting rod 51 is integrally set with an arc-shaped plate 52 that corresponds to and fits against the outer side of the rod barrel. The upper and lower ends of the arc-shaped plate 52 are respectively glued and fixed with the first fixing strap 53 and the second fixing strap 55. The sides of the first fixing strap 53 and the second fixing strap 55 are respectively provided with... The hook and loop fasteners A side 54 and B side 56 can be bonded together. The outer end of the second fixing strap 55 is provided with a fixing buckle 57 for the first fixing strap 53 to pass through. The inner side of the arc plate 52 is bonded with a rubber pad 58. In use, by attaching the arc plate 52 to the outer front end of the rod tube, and through the cooperation of the first fixing strap 53, hook and loop fastener A side 54, second fixing strap 55, hook and loop fastener B side 56 and fixing buckle 57, the reel frame 1 and its components can be connected and fixed to the outer front end of the rod tube. The rubber pad 58 plays a buffering and protective role to prevent the arc plate 52 from squeezing and abrading the outer side of the rod tube.

[0028] Furthermore, such as Figure 8 , 9As shown, it also includes a power supply assembly 6 for providing power to the drive mechanism 3. The power supply assembly 6 includes a battery 61, a connecting wire 62, a plug 63, an elastic fixing strap 64, and a socket 65. The battery 61 is detachably fixed to the front end of the outside of the rod tube via the elastic fixing strap 64. A handle 7 is fixedly installed on the outside of one of the wheel frames 1 by bolts and nuts. A socket 65 is provided at the rear end of the handle 7. A control switch 9 corresponding to the battery 61 and the DC motor 31 is provided on the outside of the handle 7. The battery 61 is correspondingly provided with a connecting wire 62 and a plug 63 for connecting to the socket 65 and the control switch 9. In use, the handle 7 facilitates the gripping and handling of the device, the elastic fixing strap 64 facilitates the fixing of the battery 61 to the outside of the rod tube, and the connecting wire 62 and the plug 63 facilitate the electrical connection of the battery 61 to the control switch 9. The principle is a mature existing technology, and its principle will not be further described here.

[0029] Specifically, DC motor 31 is a 12V DC motor, model number Weiheng Transmission 36GP-3530. In use, DC motor 31 is electrically connected to control switch 9. The principle is a mature existing technology, and its principle will not be described further here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
