Description

Technical Field

[0001] The utility model relates to the technical field of compound bows, in particular to a compound bow with an integrated main string. Background Art

[0002] Compound bows are widely used in archery competitions and archery training. With the popularization of archery sports, compound bows have increasingly come into the public eye and become a new form of leisure and entertainment. A compound bow mainly includes a bow handle assembly, a bow limb assembly, and a bow pulley assembly. By holding the grip on the bow handle assembly with one hand and pulling the bowstring between the bow pulley assemblies with the other hand, the energy stored in the deformed bow pulley assemblies is converted into the kinetic energy of the arrow, enabling the arrow to be shot at the target quickly and accurately.

[0003] The existing patent with publication number CN207703081U discloses a compound bow, which includes a bow frame, a bowstring, and a firing mechanism. The bow frame includes an upper bow limb, a lower bow limb, and a bracket. The end of the upper bow limb is equipped with an upper string pulley through an upper axle, and the end of the lower bow limb is equipped with a lower string pulley through a lower axle. The bowstring includes two sets of auxiliary strings and two main strings, and a magnetic bead seat is fixed in the middle of the two main strings. A cross string is connected between the two main strings. A hand guard extending backward is assembled at the end of the fixed seat. This solves the problem that the steel ball drops and causes misfiring. The magnetic bead seat can be stably fixed on the main string and will not roll or slide during firing.

[0004] However, the existing technology uses a method of connecting a cross string between two main strings, which is inconvenient to adjust. To solve the above technical problems, we propose a compound bow with an integrated main string. Content of the Utility Model

[0005] The purpose of the utility model is to provide a compound bow with an integrated main string to solve the problems in the existing technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A compound bow with an integrated main string includes a bow body. The two ends of the bow body are respectively installed with a first bow pulley and a second bow pulley through bow limbs. Two auxiliary strings are installed between the first bow pulley and the second bow pulley. A main string is installed between the first bow pulley and the second bow pulley, and the main string is of a ring structure.

[0007] Preferably, both the first bow pulley and the second bow pulley include a bow pulley body. Two mutually parallel main string grooves are opened on the edge of the bow pulley body. Guide grooves are provided at one end of the bow pulley body where the two main string grooves are located. A hook is provided between the two guide grooves of the bow pulley body. The two ends of the main string pass through the main string grooves of the first bow pulley and the second bow pulley and are hung on the corresponding hooks.

[0008] Preferably, a first auxiliary string groove is formed on one side of the bow wheel body, and a first hanging ear is installed on the bow wheel body on one side of the first auxiliary string groove. A second auxiliary string groove is formed on one side of the bow wheel body, and a second hanging ear is installed on the bow wheel body on one side of the second auxiliary string groove.

[0009] Preferably, a connecting rod is installed in the middle of the bow body. Two pulleys are installed at one end of the connecting rod away from the bow body, and a rolling rod is installed under the pulleys on the connecting rod.

[0010] Preferably, a grip is installed on the bow body, and a counterweight rod is adjustably installed on the bow body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. A main string is installed between the first bow wheel and the second bow wheel. The main string is of a ring structure, with a high degree of freedom and convenient adjustment.

[0013] 2. A hook is provided between the two guiding grooves on the bow wheel body; after both ends of the main string pass through the main string grooves of the first bow wheel and the second bow wheel, they are hung on the corresponding hooks. In this way, the two ends of the main string do not need to be tied firmly and can move freely, with better adjustment performance. BRIEF DESCRIPTION OF THE DRAWINGS
