Description

Technical Field

[0001] The invention relates to the field of fishing rods, in particular to a portable fishing rod. Background Art

[0002] In order to facilitate fishing, fishing rods are generally designed to be longer, but fishing rods that are too long are more troublesome to carry or store, so telescopic fishing rods came into being.

[0003] The existing telescopic fishing rod includes a plurality of shorter rod sections, which are connected in sequence, and the front rod section is telescoped inside the rear rod section, and the rear end diameter of the front rod section is larger than the front end diameter of the rear rod section, so that the front rod section can only be partially extended when it is pulled out, and the front rod section is prevented from being completely pulled out of the rear rod section. When in use, the front rod section needs to be poured out first, and then the front rod section is tightened so that the rear end of the front rod section and the front end of the rear rod section are interference-fitted to achieve the limit between adjacent rod sections, and the fishing line is installed on the frontmost rod section.

[0004] However, there are the following disadvantages in limiting the position of adjacent rod sections by interference fit: First, the strength of the interference fit between adjacent rod sections is determined by the degree to which the front rod section is pulled out of the rear rod section, but it is difficult for the user to accurately control the force when pulling out the front rod section. When the user uses less force to pull out the front rod section, resulting in a smaller interference strength between adjacent rod sections, the front rod section will be retracted into the rear rod section during the use of the fishing rod, affecting the use of the fishing rod; when the user uses more force to pull out the front rod section, or when the fish bites the hook and struggles in the water during fishing, the front rod section is pulled excessively, which will cause the interference strength between adjacent rod sections to be too large, resulting in the front rod section being unable to retract. Second, as the number of times the fishing rod is extended and retracted increases, the interference fit of adjacent rod sections continues to wear, resulting in a decrease in the limiting capacity between adjacent rod sections.

[0005] The Chinese patent application number 202320624841.4 discloses a telescopic fishing rod, the rod section of the fishing rod is divided into a handle section, a plurality of intermediate sections and a tip section, the handle section and the intermediate section are both hollow cylindrical with a thin front and a thick back, the front intermediate section is sleeved in the rear intermediate section, the rear intermediate section is sleeved in the handle section, the intermediate sections and the handle section are all interference connections, the front ends of the intermediate sections and the handle section are fixedly connected with a friction relief structure, the friction relief structure includes an outer cover body, the front end surface of the rod section where the rough surface is located is evenly provided with a plurality of through holes, a friction relief space is formed between the outer cover body and the rod section, and the friction relief space is connected to the inside of the rod section through the through holes. The scheme drips an appropriate amount of lubricating oil into the friction relief space, and the lubricating oil enters between the contact surfaces of the two rod sections through the through holes, thereby reducing the friction at the interference fit.

[0006] This patent solves the problem of difficulty in retracting the front rod section due to the large interference fit strength between adjacent rod sections by adding lubricating oil. However, the above solution cannot solve the problem of difficulty in limiting the front rod section in the extended state due to poor limiting capacity between adjacent rod sections caused by small force applied by the user or continuous wear of the interference fit between adjacent rod sections. Summary of the invention

[0007] The present invention aims to address the shortcomings in the prior art that it is difficult to accurately control the force when the front rod section is pulled out, resulting in difficulty in controlling the limiting strength between adjacent rod sections, and that the limiting capacity between adjacent rod sections decreases after the fishing rod is extended and retracted multiple times. The invention provides a portable fishing rod that is easy to extend and retract while ensuring the limiting strength between adjacent rod sections.

[0008] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0009] A portable fishing rod comprises a fixed section and a telescopic section which is arranged to guide telescopic movement at one end of the fixed section, a retraction limiting structure which drives the telescopic section to retract and be limited in the fixed section is arranged on the fixed section, the retraction limiting structure comprises a pull rope which is limited in the telescopic section at one end and passes through the fixed section axially at the other end, a winding drum which is fixedly connected with the pull rope and is used to reel in or release the pull rope is rotatably arranged at one end of the fixed section away from the telescopic section, and an anti-rotation structure which limits the rotation of the winding drum relative to the fixed section when the telescopic section is completely retracted in the fixed section is arranged between the winding drum and the fixed section A first spring is provided between the fixed section and the telescopic section to drive the telescopic section to partially extend when the anti-rotation structure is unlocked and the pull rope is released, and a first locking structure is provided to limit the relative movement of the telescopic section and the fixed section when the telescopic section is partially extended to the maximum stroke. The first locking structure includes a first locking groove recessed on the inner ring wall of the fixed section and a first locking block elastically and telescopically arranged on the outer ring wall of the telescopic section in the fixed section, which is plugged into the first locking groove when the part is extended and disengaged from the first locking groove after retraction. The elastic extension and retraction of the first locking block is controlled by the releasing or winding of the pull rope.

[0010] With the above scheme, the limiting strength between the telescopic section and the fixed section is achieved by the plugged first locking block and the first locking groove. The limiting strength is fixed, so the user does not need to accurately control his own strength. When the fishing rod is unfolded, the user unlocks the anti-rotation structure and rotates the reel in the opposite direction to release the pull rope. The telescopic section automatically extends partially to the maximum stroke under the action of the first spring. At the same time, the first locking block automatically elastically extends and plugs into the first locking groove to complete the limiting of the telescopic section, limiting the relative movement between the telescopic section and the fixed section. When recovering, it is only necessary to reel in the pull rope, first elastically retract the first locking block to disengage from the first locking groove to complete the unlocking, and then pull the telescopic section back to be completely stored in the fixed section. The anti-rotation structure limits the rotation of the reel to complete the storage of the fishing rod. The retraction of the telescopic section is more convenient, avoiding the situation where the telescopic section is difficult to retract. At the same time, compared with the existing technology where the wear degree is large due to the continuous interference fit between adjacent rod sections, the first locking groove and the first locking block are limited only by plugging, the wear amount is small, and the limiting strength is not easy to change.

[0011] Preferably, the anti-rotation structure includes a thread groove recessed at one end of the fixed section away from the telescopic section and a limiting rod having one end threadedly connected to the thread groove and the other end passing through the winding reel.

[0012] With the above solution, one end of the limit rod is fixedly connected to the fixed section through the thread groove, and the other end is interlaced with the winding drum, thereby limiting the rotation of the winding drum relative to the fixed section. When unlocking, the limit rod is rotated to disengage it from the thread groove.

[0013] Preferably, the telescopic section is provided with a first transmission block which moves back and forth axially along the telescopic section, a first traction rope which is fixedly connected to the first transmission block and the first locking block at both ends respectively, and a driving component which pushes the first transmission block to move closer to the fixed section when the pull rope is wound to pull the first locking block to elastically retract and releases the thrust on the first transmission block when the pull rope is released.

[0014] By adopting the above scheme, when the pull rope is wound up, the driving assembly drives the first transmission block to move closer to the fixed section, and the first locking block is elastically retracted by pulling the first traction rope; conversely, the pull rope is released, the thrust from the driving assembly on the first transmission block disappears, the first locking block elastically extends out and resets, and the first transmission block is pulled away from the fixed section and reset by the first traction rope.

[0015] Preferably, the driving assembly includes a driving block which is arranged in the telescopic section and is fixedly connected to the pull rope and moves close to the fixed section when the pull rope is reeled in to push the first transmission block to move close to the fixed section. A tension spring is arranged between the driving block and the telescopic section to drive the driving block to move away from the fixed section and reset when the pull rope is released.

[0016] With the above solution, when the pull rope is wound up, the driving block is pulled to move closer to the fixed section, and after the driving block moves to abut against the first transmission block, it pushes the first transmission block to move closer to the fixed section synchronously, and the tension spring is stretched to generate a reset elastic force. When the pull rope is released, the tension spring resets and drives the driving block to move away from the fixed section and reset.

[0017] Preferably, a line-reeling structure is provided between the telescopic section and the fixed section for automatically reeling in the fishing line when the telescopic section retracts into the fixed section, the line-reeling structure comprising a rotating shaft for reeling in or releasing the fishing line, which is rotatably arranged at one end of the telescopic section away from the fixed section and is fixedly connected to the fishing line, a mounting groove recessed on the telescopic section for sealing and rotating the rotating shaft and which is sealed and connected to the interior of the fixed section, a rotating fan blade protruding outwardly on the outer ring wall of the rotating shaft, and an air jet port provided on the side wall of the rotating fan blade and sealed and connected to the mounting groove, the first transmission block is in sealed sliding cooperation with the telescopic section, and the telescopic section is in sealed sliding cooperation with the fixed section.

[0018] The above scheme is adopted, compared with the prior art, when using the telescopic fishing rod, it is necessary to first unfold the fishing rod and then install the fishing line at the end of the fishing rod. When recovering, the fishing line is removed from the fishing rod and then the fishing rod is driven to retract. At the same time, the removed fishing line needs to be stored separately, the steps are cumbersome and the fishing line is easy to lose. In this scheme, when the telescopic section is sealed and retracted into the fixed section, the air squeezed in the fixed section is ejected through the jet port after passing through the installation groove. Since the jet port is set on the side wall of the rotating fan blade, the gas ejected from the jet port acts as a driving force to drive the rotating fan blade and the rotating shaft to rotate synchronously, and the rotating shaft can be rotated to reel the fishing line. There is no need to disassemble and assemble the fishing line. The fishing line is automatically reeled on the rotating shaft when the telescopic section retracts. The fishing line is not easy to lose and the steps of reeling the fishing line are reduced, which simplifies the operation and reduces time. When in use, pull the fishing line to drive the rotating shaft to rotate in the opposite direction to release the fishing line. The first transmission block is in sealing and sliding cooperation with the telescopic section, and the telescopic section is in sealing and sliding cooperation with the fixed section to ensure the sealing of the space in the fixed section, and ensure that the air is ejected from the air jet port after passing through the installation groove.

[0019] Preferably, a regular structure is fixedly provided on the telescopic section for allowing the fishing line to be regularly wound up on the rotating shaft when the rotating shaft rotates. The regular structure includes an annular groove provided on the outer ring wall of the rotating shaft for winding the fishing line and a guide sleeve provided below the annular groove for the fishing line to pass through and guide the fishing line to be wound up in the annular groove. The guide sleeve is fixed on the telescopic section.

[0020] With the above solution, since the jet nozzle sprays air outward, the jetted airflow will blow the fishing line, causing the fishing line to be unable to be neatly rolled up on the rotating shaft. Therefore, a regular structure is set up, one end of the fishing line is fixed on the rotating shaft, and the other end passes through the guide sleeve and falls below. The guide sleeve is fixed below the annular groove, and when the rotating shaft rotates to roll up the fishing line, the fishing line can be neatly rolled up in the annular groove under the guidance of the guide sleeve.

[0021] Preferably, the fixed section includes a handle section and a connecting section which is guided and telescopically arranged at one end of the handle section, the telescopic section is sealed and guided and telescopically arranged at the end of the connecting section away from the handle section, a first spring, a first locking structure and a wire-winding structure are arranged between the telescopic section and the connecting section, the cable reel is rotatably connected to the end of the handle section away from the telescopic section, and an anti-rotation structure is arranged between the handle section and the cable reel, the end of the pull rope away from the telescopic section passes through the connecting section and the handle section in sequence and is fixedly connected to the cable reel, and the pull rope and the connecting section are sealed and slidably cooperated, when the cable reel reels the pull rope, the telescopic section retracts and is stored in the connecting section and then continues to drive the connecting section to retract synchronously until it is stored in the handle section, a second spring is arranged between the connecting section and the handle section to drive the connecting section to partially extend when the anti-rotation structure is unlocked and the pull rope is released, and a second locking structure is arranged to limit the relative movement of the connecting section and the handle section when the connecting section is partially extended to the maximum stroke, and the locking or unlocking of the second locking structure is controlled by the releasing or winding of the pull rope.

[0022] With the above solution, the fishing rod in the prior art is composed of multiple rod sections, so the rod sections need to be pulled out and tightened one by one, and when retracting, they also need to be recovered one by one, which requires many repeated operation steps and is time-consuming. At the same time, when multiple rod sections are matched, there are multiple interference joints, which increases the risk of rod section retraction or jamming.

[0023] In this solution, only by winding up the pull rope, the first locking block can be retracted and unlocked, and then the telescopic section can be retracted. The retraction of the telescopic block drives the second locking structure to unlock, and then drives the connecting section to retract synchronously and be stored in the handle section. Finally, the anti-rotation structure is used to limit the rotation of the winding reel to complete the contraction of the fishing rod. Conversely, the anti-rotation structure is unlocked, the pull rope is released, and under the action of the first spring and the second spring, the telescopic section and the connecting section automatically extend to the maximum stroke, and the first locking block automatically extends elastically and inserts into the first telescopic groove for locking. Similarly, the second locking structure automatically achieves locking. The fishing rod can be unfolded and limited by controlling the release of the pull rope, and the limit can be released and the fishing rod can be retracted by controlling the winding of the pull rope. The operation is simple and time-consuming.

[0024] Preferably, the second locking structure includes a second locking groove recessed on the inner annular wall of the handle section, a second locking block elastically telescopically arranged on the outer annular wall of the connecting section in the handle section, which is plugged into the second locking groove when partially extended and disengaged from the second locking groove after retraction, a second transmission block is provided in the connecting section, which moves back and forth along the axial direction of the connecting section in a sealed manner, and a second traction rope is fixedly connected to the second transmission block and the second locking block at both ends respectively, and the movement of the second transmission block close to or away from the handle section is controlled by the retraction or extension of the telescopic section in the connecting section.

[0025] With the above solution, after the telescopic section is pulled back to contact with the second transmission block under the pull rope, the second transmission block is pushed to move closer to the handle section, and the second locking block is pulled back elastically by the second traction rope; conversely, when the pull rope is released, the thrust from the telescopic section on the second transmission block disappears, the second locking block is elastically extended and reset, and the second transmission block is pulled away from the handle section and reset by the second traction rope. The second transmission block seals and reciprocates to ensure the space in the connection section is sealed.

[0026] Preferably, at least one group of rotating blades and air jets are arranged at intervals in the circumferential direction around the rotating shaft.

[0027] By adopting the above scheme, one group can be set to drive the rotating shaft to rotate, and multiple groups can be set to further increase the driving force for the rotating shaft to rotate.

[0028] The present invention has significant technical effects due to the adoption of the above technical solution:

[0029] 1. The telescopic section and the connecting section are limited by the first locking block and the first locking groove, and the connecting section and the handle section are limited by the second locking block and the second locking groove. The limiting strength is fixed and the wear is small during use, ensuring the limiting strength;

[0030] 2. You only need to control the release of the pull rope to realize the expansion and limit of the fishing rod, and you only need to control the reeling of the pull rope to release the limit and realize the retraction of the fishing rod. The operation is simple and time-saving;

[0031] 3. When the telescopic section retracts into the connecting section, the fishing line is automatically rolled up on the rotating shaft. With the above three advantages, the fishing rod is easy to extend and retract while ensuring the limiting strength. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating fan blade 27 is vertically protruded outward on the outer ring wall of the rotating shaft 24 between the annular groove 31 and the telescopic section 2, and a jet port 28 is provided on the side wall of the rotating fan blade 27. An air passage 29 is respectively connected to the jet port 28 and the mounting groove 25 and is provided inside the rotating shaft 24 and the rotating fan blade 27. Three groups of rotating fan blades 27 and jet ports 28 are evenly spaced around the rotating shaft 24.

[0063] When the fishing rod is retracted, the reel 8 rotates forward to continuously reel the pull rope 7. The drive block 21 moves close to the reel 8 under the pull of the pull rope 7. The drive block 21 moves to push the first transmission block 16 to move close to the reel 8, and the first locking block 14 is pulled back to be separated from the first locking groove 12 by the first traction rope 19. At this time, the drive block 21 abuts against the side wall of the sliding cavity 22 close to the reel 8. Since the limit between the telescopic section 2 and the connecting section 102 is released, the telescopic section 2 and the drive block 21 move close to the reel 8 synchronously, that is, the telescopic section 2 retracts into the connecting section 102 in a sealed manner. The air in the first groove 3 is squeezed by the telescopic section 2 and then ejected from the jet port 28 through the connecting air path 26, the mounting groove 25 and the air passage 29, and the rotating shaft 24 is driven to rotate by the rotating fan blade 27, so that the fishing line 30 is neatly reeled in the annular groove 31. When the telescopic section 2 is completely retracted into the connecting section 102 , the fishing line 30 is completely rolled up on the rotating shaft 24 .

[0064] The telescopic section 2 continues to retract, driving the second transmission block 38 to slide in a sealed manner toward the winding reel 8, and the second locking block 36 is pulled back to disengage from the second locking groove 34 by the second traction rope 41. At this time, the telescopic section 2 abuts against the bottom of the first groove 3. Since the limit between the connecting section 102 and the handle section 101 is released, the connecting section 102 and the telescopic section 2 move synchronously toward the winding reel 8, that is, the connecting section 102 retracts into the handle section 101. Until the connecting section 102 is completely received in the handle section 101, the telescopic section 2 is also completely received in the connecting section 102, so the fishing rod is completely retracted. At this time, the winding reel 8 continues to be rotated so that the limit rod 10 is directly opposite to the thread groove 9, and the limit rod 10 is rotated so that the threaded section 1001 is threadedly matched with the thread groove 9, and the light rod section 1002 is plugged into the winding reel 8 to limit the rotation of the winding reel 8.

[0065] When the fishing rod is in use, the limit rod 10 is rotated to unscrew the threaded section 1001 from the threaded groove 9, and the winding drum 8 is rotated in the opposite direction to release the pull rope 7. Under the action of the second spring 6, the connecting section 102 is partially extended from the handle section 101 to the maximum stroke, and the second telescopic groove 35 is opposite to the second locking groove 34; under the action of the first spring 4, the telescopic section 2 is partially extended from the connecting section 102 to the maximum stroke, and the first telescopic groove 13 is opposite to the first locking groove 12; under the action of the tension spring 23, the driving block 21 moves away from the winding drum 8 and resets. At this time, the thrust from the telescopic section 2 on the second transmission block 38 disappears. Under the action of the fourth spring 37, the second locking block 36 partially extends and plugs into the second locking groove 34 to achieve the limit between the connecting section 102 and the handle section 101, and the second traction rope 41 drives the second transmission block 38 to move away from the winding drum 8 and reset; the thrust from the driving block 21 on the first transmission block 16 disappears. Under the action of the third spring 15, the first locking block 14 partially extends and plugs into the first locking groove 12 to achieve the limit between the telescopic section 2 and the connecting section 102, and the first traction rope 19 drives the first transmission block 16 to move away from the winding drum 8 and reset. The air enters the first groove 3 through the air jet 28, the air passage 29, the mounting groove 25 and the connecting air path 26 to replenish air, ensuring the smooth extension of the telescopic section 2. After the fishing rod is unfolded, the end of the fishing line 30 is pulled to drive the rotating shaft 24 to rotate and release the fishing line 30.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
