TECHNICAL FIELD
[0001] The utility model relates to weapon field more specifically, relate to a kind of composite bow main string length regulator and composite bow. BACKGROUND
[0002] As an important member in modern archery, composite bow is widely loved by archers for its high efficiency, high precision and adjustability. Compared with traditional long bow or recurve bow, composite bow adopts more complex bow arm structure and materials, such as carbon fiber and alloy, to provide greater elastic force and more stable tension curve. This design not only improves the accuracy and distance of shooting, but also reduces the fatigue of archers when holding the bow for a long time.
[0003] The current composite bow string length adjustment process is relatively complex, and after adjustment, the length of the bow string must be fixed using a locking mechanism. However, during the locking process, due to the large tension of the bow string, the bow string is prone to rebounding and loosening. This not only increases the difficulty of adjustment, but also may cause the adjusted bow string length to be inaccurate, affecting the accuracy and safety of shooting. In addition, the traditional locking mechanism is often complex in structure and cumbersome to operate, which is not conducive to the archer to quickly and accurately complete the adjustment of the bow string length in an emergency. Therefore, it is particularly important to design a composite bow main string length regulator that can simplify the adjustment process of the bow string length while effectively preventing the bow string from rebounding. SUMMARY
[0004] To solve the technical problem of the existing technology that the length of the composite bow string is difficult to adjust, the present scheme provides a composite bow main string length regulator to adjust the tension of the main string of the bow. Through the design of the regulator, the user can conveniently adjust the length of the main string of the composite bow, thereby changing the tension of the bow string to adapt to different shooting needs and personal preferences of the archer.
[0005] To achieve the above purpose, the technical scheme provided by the utility model is:
[0006] The present application provides a composite bow main string length regulator, comprising
[0007] A sliding device is provided on the pulley block of at least one end of the composite bow, and is fixedly connected with the end of the main string of the composite bow;
[0008] An adjusting device is connected to the sliding device, which changes the position of the sliding device at the pulley block to adjust the tension of the main string of the composite bow.
[0009] The sliding device is fixed on the pulley block and connected with the end of the compound bow. By operating the adjusting device, the position of the sliding device on the pulley block can be changed. When the tension of the main string needs to be increased, the sliding device is adjusted by the adjusting device, and the main string is pulled to shorten it. Conversely, if the tension of the main string needs to be reduced, the sliding device is only moved by the adjusting device to release the main string. During the whole process, only the adjusting device is needed to easily adjust the tightness of the main string, which is simple to operate.
[0010] In the compound bow main string length adjuster provided in the application, further, the sliding device includes a first sliding block and a second sliding block, one main string is connected to each of the first sliding block and the second sliding block, and the first sliding block and the second sliding block are arranged in parallel. The first sliding block and the second sliding block are driven by the adjusting device to move synchronously in the same direction or opposite directions. The first sliding block and the second sliding block can be applied to the synchronous adjustment of the tension of the two main strings of the compound bow. The first sliding block and the second sliding block are respectively fixed with one main string. By the adjusting device, the first sliding block and the second sliding block can be moved synchronously in the same direction or opposite directions, so that the lengths of the two main strings can be adjusted synchronously with the sliding blocks, thereby improving the accuracy and consistency of the length adjustment of the two main strings. In addition, the first sliding block and the second sliding block are respectively connected with the two main strings, so that the forces acting on the first sliding block and the second sliding block are counteracted, ensuring that the compound bow main string length adjuster does not have a biased pulling force relative to the pulley block, making the compound bow main string length adjuster more stable and the length adjustment of the main string easier.
[0011] In the compound bow main string length adjuster provided in the application, further, the adjusting device includes a rotating shaft handle, the first shaft column and the second shaft column are coaxially fixedly connected at both ends of the rotating shaft handle,
[0012] The first shaft column is provided with a right-handed thread, which is threadedly connected with the first sliding block;
[0013] The second shaft column is provided with a left-handed thread, which is threadedly connected with the second sliding block.
[0014] The rotating shaft handle is used to drive the first shaft column and the second shaft column to rotate synchronously. Since the first shaft column is provided with a right-handed thread and the second shaft column is provided with a left-handed thread, the first shaft column is threadedly connected with the first sliding block, and the second shaft column is threadedly connected with the second sliding block. When the first shaft column and the second shaft column rotate synchronously, the first sliding block and the second sliding block can slide synchronously in the same direction or opposite directions, thereby realizing the synchronous contraction or relaxation of the two main strings. In addition, since the first sliding block and the second sliding block are threadedly connected with the rotating shaft handle in the same direction and opposite directions respectively, they can be interlocked, effectively preventing the rebound of the bow string.
[0015] In the composite bow main string length adjuster provided in the application, further, the rotating shaft handle is provided with a slot hole or a convex column.
[0016] In the composite bow main string length adjuster provided in the application, further, the sliding device comprises a sliding rod, the sliding rod is fixed on the pulley block and is in sliding connection with the first sliding block and the second sliding block.
[0017] In the composite bow main string length adjuster provided in the application, further, the sliding rod is two, and the two sliding rods are fixed in parallel on the pulley block.
[0018] In the composite bow main string length adjuster provided in the application, further, the sliding rod is a screw with an end cap.
[0019] In the composite bow main string length adjuster provided in the application, further, the sliding device comprises a fixing seat, the fixing seat is provided with a screw hole matched with the end of the sliding rod, and the sliding rod is threadedly connected in the screw hole after passing through the pulley block.
[0020] In the composite bow main string length adjuster provided in the application, further, the sliding device is provided with a string fixing device on the side.
[0021] The application provides a composite bow comprising a composite bow main string length adjuster, which adjusts the tension of the composite bow main string.
[0022] Compared with the prior art, the technical scheme has the following beneficial effects:
[0023] The composite bow main string length adjuster provided in the application comprises a sliding device and an adjusting device. BRIEF DESCRIPTION OF DRAWINGS
