Description

Technical field:

[0001] The utility model relates to the technical field of compound bows, in particular to a left-right adjusting insert structure of a compound bow wheel group. Background technology:

[0002] The compound bow mainly includes the bow handle, bow limbs, wheel set and bowstring. Figure 5 As shown, the wheel set 2 is installed between two bow pieces 3 through a central axis and a bearing. When the compound bow is in use, the left and right positions of the wheel set 2 on the central axis need to be adjusted, and then different numbers of gaskets 7 are arranged between the left and right sides of the wheel set 2 and the bow pieces 3 to limit the position of the wheel set 2. This wheel set adjustment method requires the bow pieces, wheel set, bowstring, etc. to be completely disassembled each time the adjustment is made, and then the central axis is passed through the bow pieces, gaskets and wheel set. The operation process is very complicated, which seriously affects the adjustment efficiency of the wheel set.

[0003] In summary, the problem of rapid left and right adjustment of compound bow wheel assemblies has become a technical problem that urgently needs to be solved in the industry. Utility model content:

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a compound bow wheel group left and right adjustment insert structure, which solves the problem that the wheel group of the previous compound bow needs to be completely disassembled when adjusting the left and right, the operation is complicated and the efficiency is low.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A left-right adjustment insert structure for a compound bow wheel group comprises a wheel group mounted on a central axis, bow pieces are mounted on the central axis on both sides of the wheel group, insert pieces are respectively arranged on the central axis between the end faces on both sides of the wheel group and the bow pieces, an arc-shaped slot matching the central axis is arranged at the front end of the insert piece, the opening size of the arc-shaped slot is slightly smaller than the diameter of the central axis, the insert piece is clamped on the outer side of the central axis through the arc-shaped slot, and the two side surfaces of the insert piece are respectively in contact with and matched with the end face of the wheel group and the inner side surface of the bow piece.

[0007] The tail end of the insert is provided with a disassembly hole.

[0008] The insert is made of composite material or metal material.

[0009] The inserts include models with different thickness specifications.

[0010] The utility model adopts the above scheme and has the following advantages:

[0011] The previous gasket is replaced by an insert, and an arc-shaped slot matching the center axis is provided at the front end of the insert. The insert is clamped on the outside of the center axis through the arc-shaped slot. When adjusting the left and right position of the wheel set, there is no need to disassemble the bow pieces, wheel set, bowstring, etc., only the insert needs to be disassembled, and then inserts of different thicknesses are selected according to the gap between the end face of the wheel set and the bow pieces on both sides. The insert of the appropriate size can be clamped on the center axis to complete the operation. The operation process is simple, which greatly improves the adjustment efficiency of the wheel set.

[0018] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0019] like Figure 1-4 As shown, a left-right adjustment insert structure of a compound bow wheel group includes a wheel group 2 installed on a central axis 1, bow pieces 3 are installed on the central axis 1 on both sides of the wheel group 2, and insert pieces 4 are respectively provided on the central axis 1 between the end faces of both sides of the wheel group 2 and the bow pieces 3. The front end of the insert piece 4 is provided with an arc-shaped groove 5 matched with the central axis 1, and the opening size of the arc-shaped groove 5 is slightly smaller than the diameter of the central axis 1. The insert piece 4 is clamped on the outer side of the central axis 1 through the arc-shaped groove 5, and the two side surfaces of the insert piece 4 are respectively in contact with and matched with the end face of the wheel group 2 and the inner side surface of the bow piece 3.

[0020] The tail end of the insert 4 is provided with a disassembly hole 6 , and during disassembly, a tool can be inserted into the disassembly hole 6 to facilitate the force to disassemble the insert 4 from the central shaft 1 .

[0021] The insert piece 4 is made of a composite material or a metal material and has a certain elasticity. When the opening of the arc-shaped slot 5 is clamped onto the central shaft 1, since the opening size of the arc-shaped slot 5 is slightly smaller than the diameter of the central shaft 1, the opening of the arc-shaped slot 5 will be stretched open by the central shaft 1. When the central shaft 1 completely enters the arc-shaped slot 5, the opening of the arc-shaped slot 5 will return to its original position under the action of its own elasticity, thereby limiting the insert piece 4 and preventing the insert piece 4 from falling off the central shaft 1.

[0022] The inserts 4 include different thickness specifications and models. When adjusting the left and right positions of the wheel set 2, inserts 4 of different thicknesses can be selected for installation and use according to the gaps between the end faces of the wheel set 2 and the bow pieces 3 on both sides.

[0023] Working principle:

[0024] When adjusting the left and right positions of the wheel set 2, there is no need to disassemble the bow piece 3, the wheel set 2, the bowstring, etc., only the insert piece 4 needs to be disassembled, and then insert pieces 4 of different thicknesses are selected according to the gaps between the end faces of the wheel set 2 and the bow pieces 3 on both sides, and the insert pieces 4 of suitable sizes are clamped on the central axis 1 of the corresponding gaps, and the two side faces of the insert piece 4 are respectively contacted with the end faces of the wheel set 2 and the inner sides of the bow pieces 3 for pre-tightening and assembly, so as to complete the fixing and limiting of the wheel set 2. The operation process is simple, and the adjustment efficiency of the wheel set 2 is greatly improved.

[0025] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0026] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
