Counter mounting and connecting structure capable of automatically filling tooth gaps

Technical Field

The utility model relates to a fishing tackle field technique especially indicates a counter erection joint structure that can fill the backlash automatically.

Background

A dual-bearing reel has a clutch mechanism for coupling and decoupling a spool shaft and a pinion. If the clutch mechanism is in the clutch engagement state, the spool shaft and the pinion gear are coupled, and the spool shaft and the pinion gear rotate integrally with each other. As a result, the rotation of the handle is transmitted to the spool via the rotation transmission mechanism. On the other hand, if the clutch mechanism is in the clutch disengaged state, the coupling between the spool shaft and the pinion gear is released, and the spool shaft and the pinion gear are able to rotate relative to each other. As a result, even if the reel rotates at a high speed during the pole throwing, the rotation is not transmitted to the handle.

In order to measure and display the release amount and the line length of the winding amount of the fishing line wound on the reel, the current double-bearing reel is provided with a counter, the counter is driven by a guide wire shaft positioned in the reel, the counter is provided with a counter transmission gear, a driving gear is arranged on the guide wire shaft, and the driving gear is meshed with the counter transmission gear so as to realize connection. In the prior art, the driving gear is fixed on the lead shaft and can not move, however, because the tooth profiles of the driving gear and the counter transmission gear are very fine, under the relationship of a plurality of part combinations or after long-time use and abrasion, a tooth gap is easily generated between the driving gear and the counter transmission gear, and therefore, the stable operation of the counter is influenced. Therefore, there is a need to develop a solution to the above problems.

In view of the above, the present invention is directed to the deficiency of the prior art, and the main objective of the present invention is to provide a counter mounting and connecting structure capable of automatically filling the backlash, which can effectively solve the problem of the backlash easily generated between the driving gear and the counter transmission gear.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a counter mounting and connecting structure capable of automatically filling a tooth gap comprises a guide wire shaft, a driving gear and a counter transmission gear; the driving gear is positioned and arranged at one end part of the wire guide shaft and rotates along with the wire guide shaft, and the driving gear can be movably arranged along the axial direction of the wire guide shaft; the counter gear is located beside the driving gear and meshed with the driving gear, and the wire guide shaft is provided with an elastic piece which enables the driving gear to move outwards in the axial direction so as to enable the driving gear to keep meshed contact with the counter gear.

Preferably, the center of the end surface of the wire guide shaft is provided with a guide hole, the inner end of the driving gear extends to form a guide part, and the guide part is inserted into the guide hole and moves along the guide hole.

As a preferable scheme, the elastic member is disposed in the guide hole, and both ends of the elastic member respectively abut against between an inner bottom surface of the guide hole and an inner end surface of the guide portion.

Preferably, the elastic member is a spring.

Preferably, the driving gear and the counter gear are bevel gears.

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:

the driving gear can be movably arranged along the axial direction of the guide wire shaft and is matched with the elastic piece, the driving gear is enabled to move outwards in the axial direction, the driving gear is enabled to be in meshed contact with the transmission gear of the counter, the tooth gap is automatically filled, the tooth gap between the driving gear and the transmission gear of the counter is avoided, and therefore the counter can be enabled to stably operate for a long time.
