Description

Technical Field

[0001] The utility model belongs to the field of fishing rods and relates to a self-storage positioning structure for a telescopic fishing rod. Background Art

[0002] A telescopic fishing rod generally consists of an outer rod and an inner rod. The outer rod is sleeved outside the inner rod. When the fishing rod needs to be unfolded, the outer rod and the inner rod are moved away from each other, that is, the inner rod is pulled out from the outer rod. When the fishing rod needs to be stored, the inner rod is inserted into the outer rod so that the inner rod moves to the bottom inside the outer rod. However, there is a problem during storage. Since the outer rod and the inner rod are only in a sleeved relationship, the inner rod is prone to sliding and rotation relative to the outer rod. Therefore, the self-storage effect and portability of the fishing rod itself are not good. Summary of the Utility Model

[0003] Aiming at the problem that the telescopic fishing rod in the above-mentioned prior art has a poor self-storage effect, the utility model provides a self-storage positioning structure for a telescopic fishing rod that can position the inner rod inside the outer rod.

[0004] To achieve the above object, the technical solution adopted by the utility model is that a self-storage positioning structure for a telescopic fishing rod includes an outer rod and an inner rod sleeved inside the outer rod. One end of the outer rod is fixedly connected with a rear plug, and the rear plug is fixedly connected with a frustum portion. The frustum portion includes a large end close to the rear plug and a small end far from the rear plug. The small end is fixedly connected with a threaded rod, and the threaded rod is provided with an external thread. The threaded rod is inserted into the outer rod. One end of the inner rod close to the rear plug is fixedly connected with an inner expansion member. The inner expansion member includes an opening portion close to the rear plug and a threaded tube far from the rear plug. The threaded tube is provided with an internal thread, and the threaded tube is used for threaded connection with the threaded rod.

[0005] Preferably, the opening portion includes a plurality of limiting pieces, and the plurality of limiting pieces are evenly distributed in a ring around the axis of the threaded tube.

[0006] Compared with the prior art, the advantages and positive effects of the utility model are as follows:

[0007] By fixedly connecting a frustum portion to the rear plug and fixedly connecting a threaded rod to the frustum portion, when the inner rod is retracted into the outer rod, the threaded tube is threadedly connected with the threaded rod, and the opening portion is inserted into the gap between the frustum portion and the outer rod, so that a frictional force is generated between the opening portion and the frustum portion and the outer rod, thereby generating a resistance to the rotation between the outer rod and the inner rod. Therefore, the utility model can not only limit the rotation of the inner rod inside the outer rod, but also limit the sliding of the inner rod inside the outer rod, achieving a better self-storage positioning effect.

[0008] The structure of the utility model is simple, easy to manufacture, convenient to use, and low in manufacturing cost. Therefore, it is suitable for popularization and use. Brief Description of the Drawings

[0013] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0014] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0015] As Figure 1 , Figure 2 shown, in order to prevent the inner rod 2 stored in the outer rod 1 from sliding and rotating, a self-storage positioning structure of a telescopic fishing rod includes an outer rod 1 and an inner rod 2 sleeved in the outer rod 1. When the inner rod 2 is retracted into the outer rod 1, the self-storage is completed. On this basis, the present utility model fixedly connects a rear plug 3 at one end of the outer rod 1, and the rear plug 3 is fixedly connected with a frustum part 4. The frustum part 4 includes a large end 41 close to the rear plug 3 and a small end 42 far from the rear plug 3. The diameter of the large end 41 is greater than the diameter of the lower end. The small end 42 is fixedly connected with a threaded rod 5. The threaded rod 5 is provided with an external thread. The threaded rod 5 is inserted into the outer rod 1. One end of the inner rod 2 close to the rear plug 3 is fixedly connected with an inner expansion member 6. The inner expansion member 6 includes an opening part 62 close to the rear plug 3 and a threaded tube 61 far from the rear plug 3. The threaded tube 61 is provided with an internal thread, and the threaded tube 61 is used for threaded connection with the threaded rod 5.

[0016] Furthermore, the opening portion 62 includes a plurality of limiting pieces 621, and the plurality of limiting pieces 621 are evenly distributed in a ring around the axis of the threaded tube 61. Additionally, the diameter of the opening portion 62 is smaller than the diameter of the large end 41, larger than the diameter of the small end 42, and larger than the diameter of the threaded rod 5. Moreover, the limiting piece 621 is made of PVC material and has a certain toughness, capable of deforming.

[0017] The self-storage method of the present utility model: Retract the inner rod 2 into the outer rod 1 until the threaded rod 5 contacts the threaded tube 61 through the opening portion 62. The method for positioning the inner rod 2 within the outer rod 1: Hold the outer rod 1 with one hand and pinch the part of the inner rod 2 still outside the outer rod 1 with the other hand and rotate it, so that the threaded rod 5 is threadedly connected to the threaded tube 61. At the same time, the opening portion 62 gradually approaches the large end 41. Since the opening portion 62 includes a plurality of limiting pieces 621, one end of the opening portion 62 close to the large end 41 begins to be expanded. The gap between the large end 41 and the outer rod 1 is small. After the limiting piece 621 is inserted into the gap between them, a frictional force is generated with both of them, creating a resistance to the rotation of the limiting piece 621, that is, restricting the rotation between the outer rod 1 and the inner rod 2. At the same time, because the threaded rod 5 is threadedly connected to the threaded tube 61, the inner rod 2 is positioned and cannot slide anymore. In summary, after the present utility model is stored and positioned, it can not only restrict the rotation of the inner rod 2 within the outer rod 1, but also restrict the sliding of the inner rod 2 within the outer rod 1.

[0018] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
