Description

Technical Field

[0001] This utility model belongs to the field of fishing gear, specifically relating to an automatic air-venting fishing rod with top and bottom plugs. Background Technology

[0002] Fishing rods are fitted with end caps at both ends. The end cap at the front of the rod is called the front end cap, and the end cap at the rear is called the rear end cap. End caps prevent foreign objects such as dust, sand, and water from entering the rod, avoiding corrosion, wear, or clogging of the guide rings, thus extending the rod's lifespan. The rear end cap is connected to the rod via a detachable structure such as a threaded connection, and is used to seal the rear end of the rod to prevent the rod sections from protruding. A safety catch is usually installed on the rear end cap to connect a safety line, preventing the rod from being lost during fishing. There are two types of safety catches: one is directly fixed to the rear end of the end cap, extending beyond the end face of the end cap, which is prone to damage; the other is a pull-out connection, where dirt and sand can easily enter through the gap between the pull-out and the end cap, making it impossible to pull out and affecting usability. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] See Figure 1 This utility model relates to an automatic air-venting fishing rod with top and bottom plugs, comprising a fishing rod body 2, a rear plug 1 installed at the rear end of the fishing rod, and a front plug 3 installed at the front end of the fishing rod. See [reference needed]. Figure 2 , Figure 3 and Figure 4 The rear plug 1 includes a rear plug body 11, which includes a rear insertion section 111 that mates with the end hole of the fishing rod and a rear external section 112 placed outside the fishing rod. The rear external section 112 has a concealed cavity 113 at its rear end. The bottom of the concealed cavity 113 has a tail nail mounting hole 114 that communicates with the inner cavity 118 of the rear plug body. The nail rod 123 at the front end of the tail nail 12 is placed in the inner cavity 118 of the rear plug body through the tail nail mounting hole 114. A return spring 13 is sleeved on the nail rod 123. The nail cap 121 at the rear end of the tail nail 12 is located in the concealed cavity 113. The lower end face of the nail cap 121 mates with the bottom of the concealed cavity 113, and a slip ring 125 is provided on the upper end face. In normal use, the safety ring 125 is located inside the concealed cavity 113, with its upper end face lower than the upper end face of the concealed cavity 113. During the use of the fishing rod, the safety ring 125 can be prevented from contacting the ground or other objects, thus protecting the safety ring 125.

[0025] See Figure 3 The rear insertion section 111 has a lower vent hole 117 at its front end that communicates with the inner cavity 118 of the rear plug, and an upper vent hole 115 at the bottom of the concealed cavity 113 that mates with the lower end face of the nail cap 121. In this embodiment, the inner cavity 118 of the rear plug is sealed with an inner cavity sealing gasket 116, and a lower vent hole 117 is provided on the inner cavity sealing gasket 116.

[0026] In this embodiment, the slip ring 125 and the nail head 121 are integrally formed, which is simple to process and easy and reliable to connect. The integrally formed tail nail can rotate 360 ​​degrees when returning to its original position or under tension.

[0027] See Figure 4 and Figure 6 The lower end face 122 of the nail head is an arc surface. The arc surface at the bottom of the concealed cavity 113 matches the arc surface of the lower end face 122 of the nail head. When the tail nail 12 returns to its original position, the lower end face 122 of the nail head can block the far arc surface of the upper vent hole 115. The sealing effect between the arc surfaces is better than that of the flat surface, effectively preventing mud and sand from entering and avoiding the situation where the tail nail (handle ring) is blocked during secondary pulling.

[0028] See Figure 7 The rear plug body cavity 118 has a guide sleeve 119 coaxial with the tail pin mounting hole 114. One end of the return spring 13 abuts against the bottom of the guide sleeve 119, and the other end is limited by a limiting member provided on the tail pin 12. In this embodiment, the end of the tail pin 12's shank 123 has a threaded section 124, which mates with the limiting member. The nut 14 mates with the threaded section 124, making disassembly simple and position adjustment convenient.

[0029] Adjust the return spring 13 to ensure that, under normal use, the lower end face 122 of the nail head 12 fits against the bottom of the concealed cavity 113, sealing the upper vent 115 to prevent mud and sand from entering. When reeling in the fishing rod, gas in the rod enters the inner cavity 118 of the rear plug through the lower vent 117. Once a certain pressure is reached, the gas pushes the nail 12 outward (during which the return spring 13 is compressed). There is a gap between the lower end face 122 of the nail head and the bottom of the concealed cavity 113. Gas in the inner cavity 118 of the rear plug is discharged through the upper vent 115, the pressure decreases, the return spring 13 resets, thereby driving the nail 12 to move inward. The lower end face 122 of the nail head fits against the bottom of the concealed cavity 113 again, sealing the upper vent 115. The rear plug is simple, and the nail can be used as a safety ring, preventing mud and sand from entering while also automatically venting air.

[0030] See Figure 8 and Figure 9The front plug includes a front plug body 31 made of an elastic material (such as rubber). The front plug body 31 includes a front insertion section 311 that mates with the front end hole of the fishing rod and a front external section 313 placed outside the fishing rod. The front insertion section 311 and the front external section 313 are internally connected. Vent holes 32 are respectively provided at the front end of the front insertion section 311 and the rear end of the front external section 313. The front insertion section 311 is polygonal prism-shaped, with the sides of the prism recessed inward to form a recessed portion 312. The front external section 313 is cylindrical, and a notch 314 is provided at the junction of the front external section 313 and the recessed portion 312. The front plug has low resistance when inserted and is easy to insert.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
