A rotating composite bow stop block

Abstract

This invention relates to the field of composite bow technology, specifically to a rotary composite bow stop block. The stop block is rotatably mounted and cylindrical. Its surface has an annular groove for constraining the bowstring. When the bowstring collides with the stop block, a cutting action also occurs between the bowstring and the stop block. Therefore, the stop block's rotation significantly reduces wear on both the stop block and the bowstring, while also reducing noise. This reduces the reaction force of the stop block on the bowstring, thus promoting stability of the magnetic base and improving shooting accuracy. Furthermore, the constraint of the bowstring by the annular groove further enhances the accuracy of steel ball firing.

Description

Technical Field

[0001] This invention relates to the field of composite bow technology, specifically to a rotary composite bow stop block. Background Technology

[0002] A string stopper (or string stopper) in a compound bow is a device installed on the bow. Its main function is to reduce the vibration and noise of the bowstring rebounding, protect the bow, and improve shooting accuracy and comfort. String stoppers are usually made of rubber, silicone, or composite materials, and some high-end models incorporate metal components to enhance durability.

[0003] Most existing string stop blocks are cubic in structure and are fixedly installed. The installation method typically involves creating countersunk holes in the string stop block and then fixing it to the connector using bolts. For example... Figure 6 As shown, utility model application CN202322181111 provides a technical solution for a double-stop string structure, including a support frame, an upper damping rod and a lower damping rod fixedly mounted on the support frame, and stop string blocks respectively fixedly mounted on the free ends of the upper and lower damping rods. However, the cubic structure and fixed stop string blocks have the following drawbacks:

[0004] 1. When the bowstring collides with the front end of the stop block, the bowstring also cuts along the surface of the stop block, which can accelerate the wear of the bowstring and the stop block.

[0005] 2. Since the string stop block is fixed, the above-mentioned collision and cutting actions are quite noisy and are not conducive to further buffering of the bowstring and its connected compound bow components.

[0006] 3. Due to the lack of the aforementioned buffering effect, the bowstring experiences additional resistance, which becomes an interference factor, affecting the stability of the magnetic base connected to the bowstring to attract the steel ball. The instability of the magnetic base then affects the shooting accuracy of the steel ball.

[0007] For the reasons mentioned above, it is necessary to improve the existing technology. Utility Model Content

[0008] This invention discloses a rotary composite bow stop block, which addresses the problems described in 1-3 of the prior art.

[0009] To achieve the above objectives, the technical solution of this invention is as follows:

[0010] A rotary composite bow stop block includes two opposing fixed plates, with a cylindrical stop block rotatably connected between the front ends of the two fixed plates.

[0011] Preferably, the outer surface of the stop block is provided with annular grooves on the left and right sides for engaging with the bowstring.

[0012] Preferably, a connecting plate is fixedly connected between the rear ends of the fixed plates, a fixed shaft is coaxially provided at both ends of the stop block, a bearing is embedded at the front end of the fixed plate, and the fixed shaft is used in conjunction with the bearing.

[0013] Preferably, the bottom of the connecting plate is fixedly connected to a fixing block extending to the rear.

[0014] Preferably, the rear end of the fixing block is fixedly connected to the string-splitting plate of the compound bow via a connecting rod, and string-splitting pulleys are fixedly connected to the left and right sides of the fixing block, respectively.

[0015] Preferably, the front end of the dividing string plate is provided with a through groove, and the connecting rod passes through the through groove and is fixedly connected to the dividing string plate by the first fixing bolt.

[0016] Preferably, the dividing plate is provided with a positioning hole 1 that communicates with the through groove, and the connecting rod is provided with a plurality of positioning screw holes 1 evenly distributed along the front-back direction for coarsely adjusting the position of the stop block, and the first fixing bolt passes through the positioning hole 1 and is screwed into the positioning screw hole 1.

[0017] Preferably, the upper left and right sides of the fixed block are evenly distributed with positioning screw holes II for fine-tuning the position of the stop block. The connecting plate is provided with multiple positioning holes II that cooperate with the positioning screw holes II. The positioning holes II and the positioning screw holes II are fixedly connected by a second fixing bolt.

[0018] The beneficial effects of this novel rotary composite bow stop block are as follows:

[0019] This new design can reduce wear between the bowstring and the stop block, reduce noise, and improve the stability of the magnetic base by reducing the reaction force of the stop block on the bowstring through buffering, thereby effectively improving shooting accuracy.

[0028] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] The following embodiments can be understood as explaining a partial structure of the present invention individually, or as explaining a larger structure of the present invention through a combination of multiple embodiments.

[0030] First, it needs to be explained that:

[0031] like Figure 6 As shown, the existing composite bow structure, taking the utility model with application number CN202322181111 as an example, includes: a string stop block A10; a bow handle 20; a bow plate 30; a pulley 40; a bow string 50; a string splitter plate 60; and a magnetic base 70. The composite bow structure involved in this invention can refer to the prior art. Contents not mentioned are solved by existing solutions. In this invention, the relevant structure of the string stop block of the existing composite bow is improved.

[0032] Example 1

[0033] A type of rotary composite bow stop block, such as Figure 1-3 As shown, it includes two fixed plates 1 arranged opposite each other, and a cylindrical stop block 2 is rotatably connected between the front ends of the two fixed plates 1.

[0034] In this embodiment, the fixing plate 1 serves as a connector to the composite bow string middle plate 60. Its connection can be achieved in various ways disclosed in the prior art. The improvement of this invention is that the stop block 2 is rotatably set and is cylindrical. When the bowstring 50 collides with the stop block, a cutting action (such as the action between a saw chain and wood) will also occur between the bowstring and the stop block. Therefore, the stop block can significantly reduce the wear of the stop block and the bowstring through its own rotation, while reducing noise and reducing the reaction force of the stop block on the bowstring, thereby promoting the stability of the magnetic base 70 and improving the accuracy of steel ball shooting.

[0035] Example 2

[0036] As an improvement, such as Figure 1 , 3 As shown in Figures 4 and 5, the outer surface of the stop block 2 is provided with annular grooves 3 on the left and right sides respectively for cooperating with the bowstring 50.

[0037] In conventional bowstring stop blocks 2, the annular groove 3 is not provided. When the bowstring 50 collides with the bowstring stop block 2, the bowstring 50 is prone to vibration in the left and right directions, which further aggravates the instability of the bowstring 50 itself, thereby causing the magnetic base 70 to become unstable and resulting in a decrease in shooting accuracy. This new invention, by providing the annular groove 3, constrains the position of the bowstring 50 when it collides with the bowstring stop block 2, greatly reducing the amplitude of the left and right sway of the bowstring 50, thereby improving shooting accuracy.

[0038] Example 3

[0039] like Figure 3 As shown, a connecting plate 6 is fixedly connected between the rear ends of the fixed plate 1, a fixed shaft is coaxially provided at both ends of the stop block, a bearing is embedded at the front end of the fixed plate, and the fixed shaft is used in conjunction with the bearing.

[0040] like Figure 4 As shown, the bottom of the connecting plate 6 is fixedly connected to a fixing block 7 extending to the rear.

[0041] like Figure 4 As shown, the rear end of the fixing block 7 is fixedly connected to the string splitting plate 60 of the compound bow via a connecting rod 701, and string splitting pulleys 9 are fixedly connected to the left and right sides of the fixing block 7 respectively.

[0042] This embodiment provides a form of connection between the present invention and a composite bow, wherein the string separator pulley 9 is fixedly connected to the fixing block 7 via a pulley bracket.

[0043] Example 4

[0044] like Figure 4 , 5As shown, the front end of the dividing string plate 60 is provided with a through groove, and the connecting rod 701 passes through the through groove and is fixedly connected to the dividing string plate 60 by the first fixing bolt (not shown in the figure).

[0045] like Figure 4 As shown, the dividing plate 60 is provided with a positioning hole 601 that communicates with the through groove, and the connecting rod 701 is provided with a number of positioning screw holes 702 evenly distributed along the front and rear direction for coarsely adjusting the position of the stop block 2. The first fixing bolt passes through the positioning hole 601 and is screwed into the positioning screw hole 702.

[0046] like Figure 5 As shown, the upper left and right sides of the fixed block 7 are evenly distributed with positioning screw holes 703 for fine-tuning the position of the stop block 2. The connecting plate 6 is provided with multiple positioning holes 61 that cooperate with the positioning screw holes 703. The positioning holes 61 and the positioning screw holes 703 are fixedly connected by the second fixing bolt.

[0047] This embodiment provides a further improved form. In order to achieve the best matching effect between the bowstring and the stop block, the distance between the stop block and the bowstring can be adjusted by combining coarse and fine adjustments.
