Description

Technical Field

[0001] The utility model belongs to the technical field of rear plugging of fishing rods, and in particular relates to an automatic hand ring for rear plugging of fishing rods. Background Art

[0002] As an accessory on the fishing rod, the back plug of the fishing rod can protect the tail of the fishing rod, prevent impurities such as sand from entering the fishing rod, and can also play a certain decorative effect. It has been widely used in the field of fishing rod accessories. The back plug of the fishing rod usually has a hand ring to prevent the fishing rod from falling into the water due to accidental fall.

[0003] At present, the existing hand-release ring on the back plug of the fishing rod is usually an integral structure or a fixed connection structure with the back plug and the hand-release ring, which does not have a retractable function, resulting in the hand-release ring extending outside when in use, which is easy to cause an impact. For this reason, we propose an automatic hand-release ring on the back plug of the fishing rod. Utility Model Content

[0006] Preferably, a back cover is provided at the bottom of the shell, and the back cover is fixedly connected to the bottom of the shell by snap-fitting.

[0007] Preferably, a clamping groove is provided at the inner bottom end of the shell, and the clamping groove is an annular structure, and the clamping groove is provided around the inner wall of the inner bottom end of the shell.

[0008] Preferably, a snap-fitting protrusion is provided on the outer periphery of the top end of the rear cover, and the snap-fitting protrusion is an annular structure. The rear cover forms a snap-fitting state with the housing through the snap-fitting protrusion and the snap-fitting groove.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The spring-compressed part is inlaid with a retaining ring and a displacement piece to form an axial constraint, so that when the spring-compressed part is in a compressed state, it will not be pulled out under the action of external force, so that the displacement piece and the spring-compressed part form a linkage, thereby realizing the function of automatic extension and retraction of the hand ring.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 The utility model provides a technical solution for an automatic losing ring at the back of a fishing rod: it includes a shell 6, a spring-loaded part 5 and a displacement part 4. A through groove is provided on the top of the shell 6, a losing ring 8 is provided inside the through groove, a spring-loaded part 5 is fixedly connected to the bottom of the losing ring 8, a displacement part 4 is provided at the bottom of the spring-loaded part 5, the spring-loaded part 5 and the displacement part 4 are engaged with each other through triangular teeth, a boss inclined surface 7 is provided on the inner wall of the top end of the shell 6, a spring 1 is provided at the inner bottom end of the shell 6, and a retaining ring 3 is provided at the bottom of the spring-loaded part 5.

[0017] Specifically, a rear cover 2 is disposed at the bottom of the housing 6 , and the rear cover 2 is fixedly connected to the bottom of the housing 6 by snap-fitting.

[0018] Specifically, a clamping groove 9 is provided at the inner bottom end of the shell 6 . The clamping groove 9 is an annular structure and is provided around the inner wall of the inner bottom end of the shell 6 .

[0019] Specifically, a snap-fitting protrusion 10 is provided on the outer periphery of the top end of the rear cover 2 . The snap-fitting protrusion 10 is an annular structure. The rear cover 2 is snap-fitted with the housing 6 through the snap-fitting protrusion 10 and the snap-fitting groove 9 .

[0020] In the present embodiment, in the absence of external force, the spring-compressed part 5 and the displacement part 4 are acted upon by the elastic force of the spring 1, and the two triangular teeth of the two end faces are identical and mesh with each other, and there is a seven-degree angle between the midline of the triangular tooth top of the spring-compressed part 5 and the midline of the triangular tooth bottom of the displacement part 4, and the spring-compressed part 5 is stationary in the slideway of the outer shell 6 with a diameter of 10 mm. When the spring-compressed part 5 is pressed, the spring-compressed part 5 and the displacement part 4 move linearly along the inner slideway of the outer shell 6 under the action of external force. When the spring-compressed part 5 and the displacement part 4 move to the highest point of the inclined surface 7 of the inner boss of the outer shell 6 and exceed the highest point, the displacement part 4 slides out of the inner slideway of the outer shell 6, releasing the radial constraint of the slideway on the displacement part 4. Under the action of the spring 1, the triangular teeth on the end faces of the spring-compressed component 5 and the displacement component 4 are fully meshed. When the external force acting on the spring-compressed component 5 disappears, the reaction force applied by the spring 1 causes the spring-compressed component 5 and the displacement component 4 to move linearly in opposite directions. When the displacement component 4 moves to the highest point of the inclined surface 7 of the inner cavity of the shell 6, the triangular end face of the displacement component 4 contacts the inclined surface 7 of the boss of the shell 6, and moves angularly from high to low along the inclined surface 7 of the boss in the shell 6 with the center of the displacement component 4 as the axis. When the three radial bosses of the displacement component 4 move to the inner cavity R of the shell 6, the displacement component 4. The spring-compressed component 5mm slideway, since the diameter of the radial boss of the displacement component 4 is larger than the diameter of the inner cavity R of the shell 6. The spring-compressed component 5mm slideway, the displacement component 4 stops moving due to the constraint of the side wall of the slideway. The spring-compressed component 5 and the displacement component 4 also stop moving passively under the constraint of the retaining ring 3. The spring-compressed part 5 has completed its retraction; when the spring-compressed part 5 is pressed again, the spring-compressed part 5 causes the position-changing part 4 to make the same movement as before, and the position-changing part 4 moves angularly into the slideway of the outer shell 6 with a diameter of 10 mm. Since the 10 mm slideway diameter is larger than the radial boss diameter of the position-changing part 4, the position-changing part 4 and the spring-compressed part 5 move linearly along the slideway to their initial positions.
