Description

Rod body quick combination structure

technical field

The utility model relates to a fast coupling structure of a rod body used for assembling a fishing net or a fishing rod support frame.

Background technique

Press, please refer to Fig. 1, which is a cross-sectional view of a known rod body joint structure. The rod body 1 uses a front bracket as a fishing rod support frame (not shown) for positioning of a rear bracket (not shown). At any position of the shaft of the rod body 1, and the front end of the rod body 1 and the rear bracket are respectively provided with a generally U-shaped hanging seat (not shown) for placing the fishing rod, so that the fishing rod straddles the predetermined position. In terms of height, the rod body 1 is formed by a hollow inner tube 2 and a hollow outer tube 3 mutually utilizing a joint structure, and the joint structure is fixed at the end of the outer tube 3 corresponding to the inner tube 2. A hollow connecting sleeve 4 is provided, and one end of the connecting sleeve 4 corresponding to the inner pipe 2 is formed with an equidistant ring with a tapered section 5 with several slits, and an inner edge corresponding to the tapered section 5 is screwed on the connecting sleeve 4 Tighten one end of the sleeve 6 to change the diameter of the taper section 5 of the connection sleeve 4, and the inner tube 2 is placed in the outer tube 3 after passing through the taper section 5 and the connection sleeve 4, and can be used The tightening sleeve 6 is screw-locked on the connecting sleeve 4, so that the connecting sleeve 4 can use the taper section 6 to tighten the inner tube 2 for adjusting the length of the rod body 1, and then fix the inner tube 2 and the outer tube 3 to support the fishing rod Effect.

However, in the known joint structure used for the rear bracket of the fishing rod, although the tight sleeve 6 can be unscrewed to adjust the extension length of the inner tube 2, when in use, the inner tube 2 is usually extended to the longest length, and then locked. Adjust the compression sleeve 6 to fix the inner tube 2 and the outer tube 3 so that the inner tube 2 cannot slide along the axial direction of the outer tube 3, but if the locking force of the compression sleeve 6 is insufficient, the tapered section 5 The radial bite force of the tightened inner tube 2 is insufficient, and it is easy to slip, causing the inner tube to loosen in the radial direction, which affects its support for the fishing rod, so it cannot effectively provide the radial fixing effect between the inner tube 2 and the outer tube 3 , and at the same time, because the joint structure has many components, and it is necessary to use appropriate force to lock and unscrew the adjustment compression sleeve 6, so the convenience of adjusting the joint is insufficient, which is quite time-consuming and laborious.
