[0034] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, and those skilled in the art will appreciate that these descriptions are merely descriptive, exemplary, and should not be interpreted as limiting the scope of protection of the present application.

[0035] It should be noted that similar reference numerals represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it can no longer be further defined and explained in subsequent drawings.

[0036] This embodiment mainly describes a fishing gear telescopic rod quick locking structure capable of being quickly locked or unlocked by one hand, and the specific implementation is as follows:

[0037] Embodiment I

[0038] As shown in Figures 1-6 , the fishing gear telescopic rod quick locking structure comprises an outer rod 1, an inner rod 2, a mounting block 3, and a locking slider 4. The outer rod 1 adopts a tubular structure. The mounting block 3 is fixed to one end of the inner rod 2. A helical groove 31 is formed in the side wall of the mounting block 3. The distance between the groove bottom of the helical groove 31 and the side wall of the inner rod 2 gradually changes. The locking slider 4 is slidingly arranged in the helical groove 31. The inner wall of the locking slider 4 is attached to the groove bottom of the helical groove 31. The inner wall of the locking slider 4 and the groove bottom of the helical groove 31 are smoothly arranged. The locking slider 4 and the mounting block 3 can be inserted into the outer rod 1 together with the inner rod 2. The inner rod 2 can be telescopically and rotatably moved relative to the outer rod 1.

[0039] Preferably, the side wall of the inner rod 2 is a cylindrical side wall. The helical groove 31 can be provided with one or less than one or more turns. The distance between the groove bottom of the helical groove 31 and the side wall of the inner rod 2 gradually changes.

[0040] In this embodiment, the helical groove 31 is provided with an abutment surface 32. One end of the groove bottom of the helical groove 31 is connected to one side of the abutment surface 32. The other end of the groove bottom of the helical groove 31 is connected to the other side of the abutment surface 32. The shortest distance between the intersection of the groove bottom of the helical groove 31 and one side of the abutment surface 32 and the central axis of the inner rod 2 is L1. The shortest distance between the intersection of the groove bottom of the helical groove 31 and the other side of the abutment surface 32 and the central axis of the inner rod 2 is L2. The value of L1 is greater than the value of L2, and the value gradually decreases from L1 to L2.

[0041] When the locking slider 4 is located in the spiral groove 31, the end of the locking slider 4 away from the stop surface 32 is the working end. The shortest distance between the outermost part of the working end and the central axis of the inner rod 2 is L3. The value of L3 is greater than the radius of the inner rod 2, and there is friction between the outer wall of the working end and the inner wall of the outer rod 1.

[0042] When the inner rod 2 rotates toward the stop surface 32, the friction between the locking slider 4 and the outer rod 1 will generate a sliding force on the locking slider 4 toward the stop surface 32, causing the locking slider 4 to slide in the spiral groove 31, and reducing the friction between the locking slider 4 and the outer rod 1. The gap between the inner rod 2 and the outer rod 1 will increase, and the inner rod 2 can drive the locking slider 4 to extend and retract relative to the outer rod 1.

[0043] Conversely, the friction between the locking slider 4 and the outer rod 1 increases, and the locking slider 4 can fill the gap between the inner rod 2 and the outer rod 1, and restrict the extension, contraction and rotation of the inner rod 2 relative to the outer rod 1.

[0044] To ensure stable telescopic adjustment of the inner rod 2 within the outer rod 1, the inner diameter of the outer rod 1 remains consistent within the telescopic range of the inner rod 2 within the outer rod 1.

[0045] In this application, by setting the spiral groove 31 on the inner rod 2, sliding the locking slider 4 in the spiral groove 31, and allowing the inner wall of the outer rod 1 to drive the locking slider 4 to slide in the spiral groove 31 through friction, when the inner rod 2 and the outer rod 1 are relatively stationary, rotating the inner rod 2 or the outer rod 1 with one hand can expand or shrink the gap between the inner rod 2 and the outer rod 1 during the sliding process, thereby increasing or decreasing the friction between the locking slider 4 and the inner wall of the outer rod 1. This achieves the relative locking or unlocking of the inner rod 2 and the outer rod 1, and the telescopic movement can be achieved by rotating with one hand. The telescopic movement can be unlocked and then extended or locked and then restricted. The operation is simple and quick.

[0046] like Figures 2-3 As shown, the mounting block 3 is provided with a first insertion part 3a that is fixedly connected to the inner rod 2. The first insertion part 3a can be fixedly installed to the inner rod 2 by means of insertion, threaded connection or side screws, etc. The mounting block 3 is also provided with a second insertion part 3b that is exposed outside the inner rod 2. A spiral groove 31 is opened on the side of the second insertion part 3b. The outer diameter of the second insertion part 3b is larger than the outer diameter of the inner rod 2.

[0047] Meanwhile, to ensure friction between the inner wall of the outer rod 1 and the outer wall of the locking slider 4, the maximum distance between the insertion part 3b and the outer wall of the locking slider 4 is L4, and the value of L4 must be greater than the inner diameter of the outer rod 1.

[0048] To prevent the second insertion part 3b from being inserted into the inner rod 2, the second insertion part 3b is provided with a lower cover plate 3b2 that abuts against one end of the inner rod 2.

[0049] In this embodiment, the second insertion part 3b is also provided with an upper cover plate 3b1 and a connecting post 3b3 located between the upper cover plate 3b1 and the lower cover plate 3b2. The side wall of the connecting post 3b3 is the stop surface 32 and the bottom of the spiral groove 31. The outer diameter of the upper cover plate 3b1 and the lower cover plate 3b2 is larger than the outer size of the connecting post 3b3. The locking slider 4 is located between the upper cover plate 3b1 and the lower cover plate 3b2. When the inner rod 2 and the outer rod 1 move in extension and retraction, the upper cover plate 3b1 and the lower cover plate 3b2 can restrict the locking slider 4 from falling.

[0050] Preferably, the mounting block 3 can be integrally formed or composed of partially fixed components.

[0051] Example 2

[0052] like Figure 4 As shown, the technical feature that differs from Embodiment 2 is that the outer diameter of the second insertion part 3b is less than or equal to the outer diameter of the inner rod 2.

[0053] Example 3

[0054] like Figure 5 As shown, the technical feature that differs from Embodiment 1 or Embodiment 2 is that the mounting block 3 is not provided, and the spiral groove 31 is directly opened on the side wall of the inner rod 2.
