Description

Technical Field

[0001] The present application relates to the technical field of recurve bows, and in particular to a recurve bow handle structure that facilitates bowstring correction. Background Art

[0002] The recurve bow is a commonly used bow for competition, hunting, and entertainment, and is mainly composed of a bow handle and bow pieces assembled at both ends of the bow handle; the patent name in the prior art is a dual-purpose bow handle for a recurve bow (application number 202020168581.0), which includes a bow handle main body and bow piece mounting devices respectively arranged at the two ends of the back side of the bow handle main body; the bow piece mounting device includes an embedded nut embedded in the bow handle main body, a pressing screw threadedly assembled with the embedded nut, and a copper sleeve that can be threadedly assembled on the pressing screw; copper sleeve storage countersunk holes for inserting copper sleeves are respectively provided at the two ends of the back side of the bow handle main body. When assembling the bow piece, the end of the pressing screw is slightly screwed into the copper sleeve, and the copper sleeve can be pulled out of the copper sleeve storage countersunk hole by pulling the pressing screw; then remove the pressing screw from the pressing screw The copper sleeve is removed from the end of the wire, and the copper sleeve is reversed so that the pressure screw is threadedly assembled into the copper sleeve from the other end of the copper sleeve (the end without the convex ring). When the copper sleeve is completely assembled on the pressure screw, the pressure screw with the copper sleeve is assembled on the embedded screw. At this time, the U-shaped interface on the bow piece is clamped with the copper sleeve. At the same time, the locating pin on the bow piece is engaged with the locating groove provided on the locating block to complete the assembly of the bow piece with the U-shaped interface and the bow handle. It can be seen from the above-mentioned prior art that when the pressure screw passes through the bow piece and is fixed on the bow handle, there is a clearance fit between the through hole provided on the bow piece and the pressure screw. When the recurve bow is used for a long time, the bow piece on the recurve bow will be offset, so that the bowstring and the bow handle are in a staggered state, and then the recurve bow cannot be used for normal shooting.

[0013] 1. When the two limbs are installed at the two ends of the bow handle, the adjustment block is inserted into the adjustment slot, and then the two locking screws are turned to move the adjustment block left and right, and then the limbs are driven to move until the bow string is aligned with the bow handle. After the recurve bow is used, if the limbs are offset, the two locking screws can be rotated and adjusted again to make the bow string and the bow handle correspond again, so that the recurve bow can be used normally, thereby improving the stability of the recurve bow;

[0014] 2. When adjusting the two limbs, just match the bowstring with the alignment groove, so that the bowstring of the recurve bow can be stably installed, which improves the convenience of installing the recurve bow;

[0015] 3. When one end of the two bow pieces are respectively installed at the two ends of the bow handle, one end of the bow piece is embedded in the recessed groove of the bow handle, so that the side wall of the bow piece is flush with the side wall of the bow handle, thereby improving the aesthetics of the recurve bow.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings.

[0023] The embodiment of the present application discloses a recurve bow handle structure that facilitates bowstring correction.

[0024] Reference Figure 1 , including a bow handle 1, two bow pieces 2 and a bowstring 3. The front sides of both ends of the bow handle 1 are respectively provided with sink grooves 4. One side of the sink groove 4 opens up one end surface of the bow handle 1. One end of the bow piece 2 is embedded in the sink groove 4. The two ends of the bowstring 3 are respectively wrapped and fixed on the outer ends of the bow piece 2.

[0025] Reference Figure 2 and Figure 3 A fixing bolt 5 is connected to the side wall of the inner end of the bow piece 2, and one end of the fixing bolt 5 passes through the side wall of the bow piece 2 and is threadedly connected to the bottom of the sink groove 4 of the bow handle 1.
