Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of composite bows, and in particular to a two-section string separator for composite bows and arrows. Background Technology
[0002] The string splitter is a crucial component of a compound bow, primarily used to ensure the stability and accuracy of the bowstring when drawn. The string splitter is typically mounted below the handle, close to the bowstring. This position ensures that the string splitter effectively guides the secondary cable (or string) during draw, thereby reducing friction and wear on the bowstring.
[0003] In the current technology, compound bows using double-sided string splitters on the market all use double-sided single pulleys. In use, because the string splitter is too wide, the hand holding the bow is blocked by the bowstring passing through the pulley, making it inconvenient to hold the bow. However, the string splitters currently on the market cannot be made too narrow, as being too narrow would reduce the distance between the bowstrings, affecting the archer's aim. Utility Model Content
[0004] This application provides a two-stage string splitter for compound bows. By adding an auxiliary string splitter wheel on each side below the frame, the bowstring is retracted inward, narrowing the gap between the lower bowstrings. This prevents the bowstring from obstructing the hand during use, thereby improving the comfort of the compound bow and the archer's accuracy.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] The two-section string separator for compound bows includes:
[0007] The support is connected to the bow body at the rear, and has protrusions at the left and right edges at the front to form connecting parts.
[0008] The mounting platform is fixedly connected to the bottom of the frame and is used to narrow the bowstring spacing;
[0009] The string splitting assembly is located on both sides of the frame and is used to split the bowstring. The string splitting assembly includes two main string splitting wheels and two auxiliary string splitting wheels. The two main string splitting wheels are rotatably connected to two connecting parts respectively, and the auxiliary string splitting wheels are rotatably connected to both sides of the mounting platform respectively.
[0010] Furthermore, the connecting part gradually tilts outward from back to front, so that the two main chord wheels are arranged in a figure-eight shape on both sides of the bracket.
[0011] Furthermore, the width of the mounting platform is smaller than the width of the bracket, so that the distance between the two secondary chord wheels is smaller than the distance between the two primary chord wheels.
[0012] Furthermore, the width of the mounting platform gradually decreases from top to bottom, so that the two secondary chord wheels are arranged in a figure-eight shape on both sides of the mounting platform.
[0013] Furthermore, a front fork is fixedly connected to the front side of the mounting platform, and a buffer pad is fixedly connected to the front end of the front fork.
[0014] In summary, this utility model has at least one of the following beneficial technical effects:
[0015] 1. This compound bow two-section string splitter, through the setting of the string splitting component, and with the spacing of the main string splitting wheel being greater than that of the secondary string splitting wheel, allows the bowstring in the archer's aiming area to be properly stretched, ensuring the archer's aiming and shooting. Meanwhile, the secondary string splitting wheel narrows the bowstring spacing in the archer's grip area, preventing the bowstring from contacting the archer's arm and affecting the archer's comfort when using the compound bow, thus effectively improving the practicality of the string splitter.
[0016] 2. The two-section string splitter of this compound bow, by setting an inclined connecting part, allows the bowstring to be completely pressed into the groove of the main string splitter when it retracts after passing through it. This effectively increases the contact area between the bowstring and the main string splitter, avoids friction between the bowstring and the side wall of the main string splitter which would aggravate bowstring wear, and effectively improves the service life of the bowstring, thereby extending the service life of the compound bow.
[0017] 3. This compound bow's two-section string splitter, by gradually reducing the width of the mounting platform from top to bottom, positions two secondary string splitting wheels in a V-shape on both sides of the platform. When the bowstring passes through the main string splitting wheel and connects to the secondary string splitting wheel, the inclined secondary string splitting wheel actively accommodates the narrowing bowstring, ensuring the bowstring fits completely within the groove of the secondary string splitting wheel. This allows for even force distribution on the bowstring, preventing localized wear and further extending the bowstring's lifespan and reducing the cost of using the compound bow.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example:
[0027] Reference Figures 1-5 The composite bow and arrow two-section string separator disclosed in this utility model includes:
[0028] The bracket 1 is connected to the bow body 7 at its rear side, and the connecting parts 4 are protruding at the left and right edges of the front side.
[0029] Mounting platform 2 is fixedly connected to the bottom of the frame and is used to narrow the spacing of bowstring 9;
[0030] The string splitting assembly 3 is located on both sides of the frame and is used to split the bowstring 9. The string splitting assembly 3 includes a main string splitting wheel 31 and a secondary string splitting wheel 32. There are two main string splitting wheels 31 and two secondary string splitting wheels 32. The two main string splitting wheels 31 are rotatably connected to the two connecting parts 4 respectively, and the secondary string splitting wheels 32 are rotatably connected to both sides of the mounting platform 2 respectively.
[0031] In this embodiment, observation Figure 1 It can be observed that by providing bracket 1, and with the rear side of bracket 1 connected to the bow body 7, bracket 1 can be easily installed on the compound bow. Subsequent observation... Figure 2 It can be observed that there are protruding connecting parts 4 on the left and right edges of the front side of the bracket 1. Two main split-string wheels 31 are connected to the two connecting parts 4 respectively. When the compound bow is in use, the two main split-string wheels 31 can be used to separate the bowstring 9, keep the bowstring 9 in the correct position, prevent the bowstring 9 from interfering with the arrow when the bow is drawn, and thus improve the accuracy of shooting.
[0032] Currently, compound bows using double-sided string splitters on the market all use double-sided single pulleys. In use, the string splitter is too wide, causing the hand holding the bow to be blocked by the bowstring 9 through which the pulley passes, making it inconvenient to hold the bow. At present, the string splitter on the market cannot be made too narrow, as this would reduce the spacing between the bowstring 9, affecting the archer's aim.
[0033] Therefore, observe Figure 5 It can be observed that, Figure 5 yes Figure 2 The diagram shows a view from below. We can see that the bottom of the bracket 1 is connected to a mounting platform 2. Two secondary stringing wheels 32 are connected to each side of the mounting platform 2. The bowstring 9 passes through the main stringing wheel 31 and the secondary stringing wheels 32 in sequence, and then... Figure 1 As shown in the diagram, the lower spacing of the bowstring 9 is narrowed. When the archer grips the handle 8, the bowstring 9 will not interfere with the archer's hand. This effectively improves the archer's comfort when using the compound bow without affecting the aiming.
[0034] In a further preferred embodiment of this utility model, the main splitting wheels 31 on both sides of the bracket 1 separate the bowstring 9 at the aiming position to prevent the bowstring 9 from affecting the trajectory of the arrow. However, because the bowstring 9 is elastic, this causes the separated bowstring 9 to rub against the side wall of the main splitting wheel 31 when it comes into contact with it, thereby aggravating the wear of the bowstring 9. Therefore, observation Figure 2 It can be observed that the connecting part 4 gradually tilts outward from back to front, causing the two main stringing wheels 31 to be arranged in a figure-eight shape on both sides of the bracket 1. At this time, the bowstring 9 is as follows: Figure 1 As shown in the diagram, after passing through the main string wheel 31, the bowstring 9 retracts inward and is completely pressed into the groove of the main string wheel 31. This effectively increases the contact area between the bowstring 9 and the main string wheel 31, preventing friction between the bowstring 9 and the side wall of the main string wheel 31 from aggravating the wear of the bowstring 9. This effectively increases the service life of the bowstring 9, thereby extending the service life of the compound bow.
[0035] In a further preferred embodiment of this utility model, such as Figure 5 As shown, by making the width of the mounting platform 2 smaller than the width of the bracket 1, and the distance between the two secondary string wheels 32 smaller than the distance between the two main string wheels 31, the distance below the bowstring 9 can be effectively narrowed, so that the archer's arm will not come into contact with the bowstring 9 after holding the grip, which can effectively improve the archer's comfort and accuracy when using a compound bow.
[0036] In a further preferred embodiment of this utility model, observation Figure 1 It can be observed that because the bowstring 9 converges on the bottom reel after passing through the main string wheel 31 and the secondary string wheel 32, the significantly narrowed spacing of the bowstring 9 will compress the side wall of the secondary string wheel 32. This will cause the contact pressure between the bowstring 9 and the secondary string wheel 32 to be too concentrated, thus accelerating the wear of the bowstring 9. Therefore, observation... Figure 5 It can be observed that the width of the mounting platform 2 gradually decreases from top to bottom, so that the two secondary stringing wheels 32 are arranged in a figure-eight shape on both sides of the mounting platform 2. At this time, when the bow string 9 passing through the main stringing wheel 31 connects to the secondary stringing wheel 32, the inclined secondary stringing wheel 32 will actively meet the narrowed bow string 9, so that the bow string 9 is completely fitted into the groove of the secondary stringing wheel 32. This can be used to make the bow string 9 bear force evenly, thereby avoiding the occurrence of local wear aggravation, thus further extending the service life of the bow string 9 and reducing the cost of using the compound bow.
[0037] In a further preferred embodiment of this invention, when the compound bow releases the arrow, the bowstring 9, after returning to its original position, will spring forward due to inertia, causing the bowstring 9 to be pulled up again. This increases the recovery time of the compound bow, thereby affecting the archer's firing interval. Therefore, observation... Figure 3 It can be seen that a front fork 5 is fixedly connected to the front side of the mounting platform 2, and a buffer pad 6 is fixedly connected to the front end of the front fork 5. When the compound bow is released, the bowstring 9 will hit the buffer pad 6 when it returns to its original position, which will greatly absorb the inertial rebound of the bowstring 9, shorten the recovery time of the compound bow, and thus effectively improve the comfort of using the compound bow.
[0038] Meanwhile, the soft cushioning pad 6 can also protect the bowstring 9 while preventing it from rebounding, thus improving the practicality of the string separator.
[0039] The implementation principle of the above embodiment is as follows: the rear side of the bracket 1 is fixedly connected to the bow body 7, and then the bowstring 9 passes through the main split wheel 31 and the secondary split wheel 32 in sequence. Since the distance between the secondary split wheels 32 is smaller than the distance between the main split wheels 31, the bowstring 9 in the archer's aiming area is normally stretched to ensure the archer's aiming and shooting. The distance between the bowstring 9 in the archer's grip area is narrowed due to the action of the secondary split wheels 32, which can prevent the bowstring 9 from contacting the archer's arm and affecting the archer's comfort when using the compound bow, thereby effectively improving the practicality of the splitter.
[0040] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
