Description

Technical Field

[0001] The utility model relates to an auxiliary tool for a bow and arrow, in particular to a bow and arrow counterweight. Background Art

[0002] Bow weights, also called barebow weights, are heavy objects attached to the bow to help balance the weight of the bow and reduce the felt recoil. They can also be installed on the bow's balance bar. They can help the shooter stay on target and make follow-up shots faster and more accurately.

[0003] A Chinese patent application numbered 201620295833.X discloses a shock-absorbing counterweight for a bow: a 1-ounce standard counterweight, a 2-ounce standard counterweight, a 4-ounce standard counterweight and a rubber shock-absorbing pad are randomly combined on the connecting screws. If a heavy weight is required, more standard counterweights and fewer rubber pads are installed; if a light weight is required, fewer weights are installed.

[0004] Although the above-mentioned prior art can achieve different weighting effects by combining different weights of counterweight blocks, the minimum adjustable unit value is 1 ounce, which is not flexible enough. For shooters who are more sensitive to counterweight, the lowest adjustable unit of counterweight is still not small enough. Utility Model Content

[0005] The present application provides a bow and arrow counterweight block, which can solve the problem that the lowest adjustable unit of the bow and arrow counterweight is not small enough.

[0006] In the present application, a bow and arrow counterweight block is provided, including a counterweight empty chamber, wherein the counterweight empty chamber has a cavity, wherein the cavity is filled with filling particles, and a counterweight effect is achieved through the filling particles. The cavity is used to accommodate the filling particles, and at least one side of the cavity is open to the outside of the counterweight empty chamber for loading or pouring out the filling particles. At least one cover body is openable and closable by a threaded connection and is arranged at the opening of the cavity. A first threaded hole or a first stud is provided on the counterweight empty chamber or the cover body for achieving a connecting effect.

[0007] By adopting the above technical solution, the filling particles of different weights can be loaded into the cavity according to the needs of the user. Since the weight of a single filling particle is very small, the weight adjustment is more flexible. When shooting arrows, the filling particles will rub against each other inside the cavity, which can better absorb kinetic energy and achieve a vibration reduction effect.

[0008] In one embodiment, the counterweight empty chamber is cylindrical.

[0009] With the above technical solution, the cylindrical design usually has a standard diameter, making it easier to install on a balance pole or a bow handle.

[0010] In one embodiment, the first threaded hole or the first stud is arranged along the central axis of the counterweight empty chamber.

[0011] By adopting the above technical solution, the structural stability is better.

[0012] In one embodiment, the cavity is cylindrical, and an internal thread is provided on the inner wall of the cavity. The cover body is mainly composed of a threaded cylinder and a top cover fixedly connected together. The threaded cylinder is used to be threadedly connected to the internal thread on the inner wall of the cavity. The cross-sectional area of ​​the top cover is larger than the cross-sectional area of ​​the cavity and is located outside the cavity.

[0013] By adopting the above technical solution, the structure is easy to implement and the operation is relatively simple.

[0014] In one embodiment, the number of threads on the internal thread and the threaded cylinder is no less than two.

[0015] By adopting the above technical solution, the effect is more stable.

[0016] In one embodiment, the filling particles are made of tungsten steel.

[0017] With the above technical solution, the density of tungsten steel is higher, which means that a smaller volume can provide a larger weight when used as a counterweight, which helps to reduce the overall volume of the bow. In addition, tungsten steel has good wear resistance, stability, corrosion resistance and machinability.

[0018] In one embodiment, the filling particles are made of lead.

[0019] The above technical solution is adopted because lead has a higher density, lower cost, is easy to process, has good shock resistance, can absorb vibrations, and improves stability during shooting.

[0020] In summary, in the present application, a bow and arrow counterweight block has the following beneficial effects compared to the prior art: the counterweight weight can be adjusted more flexibly by increasing or decreasing the filling particles, and the filling particles can have a vibration reduction effect.
