Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 3, a direction adjusting assembly of a bow and arrow balance bar comprises a fixed seat 1, a joint shaft 2 and a connecting shaft 3. The connecting shaft 3 is connected to a balance bar (not shown), and the connection manner of the connecting shaft is the same as that of the fixing block and the balance bar described in the patent with the application number of 201720029910.1, which is not described in detail herein. The middle of the fixing seat 1 is processed into two corresponding side surfaces to form parallel planes, the middle of the fixing seat 1 is provided with a through hole 9 which penetrates through the fixing seat, a screw rod 10 penetrates through the through hole 9 of the fixing seat 1 during assembly, and then the screw rod 10 penetrates through the through hole 9 of the fixing seat 1 and is in threaded connection with a threaded hole (not shown in the drawing) arranged on the bow handle, so that the fixing seat 1 can be fixed on the bow handle.

As shown in fig. 1 and 3, the end of the fixed seat 1 and the end of the joint shaft 2 are both provided with bevel gears 5, and the centers of the bevel gears of the fixed seat 1 and the joint shaft 2 are both provided with threaded holes 7. The side surface of the joint shaft 2 and the side surface of the connecting shaft 3 are both provided with inwards-recessed conical holes 6, and the cross section of each conical hole 6 is of a structure with a large outside and a small inside. The bevel gear 5 is embedded into the conical hole 6 in a matching mode, and helical teeth arranged on the inner side wall of the conical hole 6 are meshed with the helical teeth of the bevel gear 5.

With reference to fig. 1 and 3, countersunk holes 8 are formed in the other side surfaces of the joint shaft 2 and the connecting shaft 3 opposite to the conical hole 6, the countersunk holes 8 coaxially penetrate through the conical hole 6, bolts 4 penetrate through the joint shaft 2 and the connecting shaft 3 from one sides of the countersunk holes 8, and the bolts 4 are matched with threaded holes 7 of the joint shaft 2 and the fixing seat 1.

As shown in fig. 1 to 3, when the joint shaft 2 is assembled and connected to the fixing base 1, the conical hole 6 of the joint shaft 2 is sleeved on the bevel gear 5 of the fixing base 1, so that the helical teeth on the inner side surface of the conical hole 6 are engaged with the helical teeth of the bevel gear 5, and then the bolt 4 is passed through the countersunk hole 8 of the joint shaft 2 to the threaded hole 7 of the fixing base 1 and screwed, so that the joint shaft 2 can be fixed to the end of the fixing base 1. When the connecting shaft 3 is assembled on the joint shaft 2, the conical hole 6 of the connecting shaft 3 is sleeved on the bevel gear 5 of the joint shaft 2 in the same method, oblique teeth on the inner side surface of the conical hole 6 are meshed with oblique teeth of the bevel gear 5, then the bolt 4 is threaded through the countersunk hole 8 of the connecting shaft 3 to the threaded hole 7 of the joint shaft 2 in the same way and is screwed, and then the connecting shaft 3 can be fixed at the end part of the joint shaft 2. Furthermore, the fixing seat 1 can be provided with a bevel gear 5 at one end or bevel gears 5 at both ends, so that a balance bar is connected to the bow handle or two balance bars are connected to the bow handle at the same time. Through the meshing of the bevel gear 5 and the conical hole 6, the connecting contact surface of the joint shaft 2 and the fixed seat 1 and the contact surface of the connecting shaft 3 and the joint shaft 2 can be increased, and the meshing capacity of the helical teeth of the bevel gear 5 and the helical teeth of the conical hole 6 can be improved, so that the fastening degree of the joint shaft 2 and the fixed seat 1 and the connecting shaft 3 and the joint shaft 2 which are connected with each other is improved, and the looseness caused by loose assembly or long-term use is avoided.

As shown in fig. 3 and 4, one end of the fixed seat 1 connected to the joint shaft 2 is a cylinder, a graduated scale 11 is arranged on the ring surface of the cylinder, and a mark 12 corresponding to the graduated scale 11 is arranged at the end of the joint shaft 2. Similarly, one end of the joint shaft 2 connected with the connecting shaft 3 is a cylinder, a graduated scale 11 is arranged on the ring surface of the cylinder, and a mark 12 corresponding to the graduated scale 11 is arranged at the end part of the connecting shaft 3. Taking the fixing base 1 as an example, an included angle between two adjacent scale marks of the scale 11 and a radius line of an axis of the fixing base is 10 °, that is, the included angle between two adjacent scale marks of the scale 11 is 10 °.

When the shooter needs to adjust the angle of the balancing pole, taking the adjustment of the angle of the joint shaft 2 relative to the fixing base 1 as an example, an inner hexagonal wrench can be used to unscrew the nut 4 screwed to the fixing base 1, pull out the joint shaft 2, make the conical hole 6 of the joint shaft 2 and the bevel gear 5 of the fixing base 1 lose the meshed state, rotate the joint shaft 2, rotate the corresponding angle by comparing the mark 12 on the joint shaft 2 with the scale mark of the scale 11 of the fixing base 1, and after the adjustment is completed, lock the bolt 4 to complete the adjustment of the joint shaft 2, that is, complete the angle adjustment of the balancing pole relative to the swing of the fixing base 1. When the angle of the connecting shaft 3 relative to the joint shaft 2 is adjusted, the connecting mode is consistent with the mode of adjusting the angle of the joint shaft 2 relative to the fixed seat 1, and the angle adjustment of the balance rod relative to the swing of the joint shaft 2 is completed after the adjustment. The universal adjustment of the balance bar relative to the bow handle can be conveniently realized through the two adjustment modes, and the use of a shooter can be greatly facilitated.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
