[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0030] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0031] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0033] like Figure 1 As shown, in the existing bow arm structure, the two guide rails (i.e., the first guide rail 2 and the second guide rail 3) at the top of the bow arm are integrally arranged with the bow arm body 1 and are integrally processed and formed. During the manufacturing process, the manufacturing process of the bow arm with this special-shaped structure is complicated and its precision is also difficult to control. The two guide rails and the bow arm body 1 are made of the same material. During use, a rubber band clamping structure (chuck) will be assembled on the guide rails, and the rubber band clamping structure can be slidably adjusted relative to the guide rails. Therefore, there are often problems that the guide rails have poor wear resistance and a short service life.
[0034] like Figure 2-Figure 3 As shown, the split-type limb structure of a slingshot proposed in this embodiment mainly includes: a limb body 1 and a first guide rail 2, the first guide rail 2 and the limb body 1 are separately arranged, and the limb body 1 has a first mounting portion 11, the first guide rail 2 is mounted on the first mounting portion 11, and the first guide rail 2 is fixedly connected to the limb body 1. In actual use, the limb body 1 and the guide rail of the limb of this embodiment are separately arranged, and the limb body 1 and the guide rails (the first guide rail 2 and the second guide rail 3) can be processed separately, which can effectively reduce the difficulty of the processing technology, and can effectively ensure the processing accuracy of the limb, and ensure the overall matching precision of the limb.
[0035] Specifically, the material of the first guide rail 2 of the present embodiment is different from the material of the limb body 1, and the hardness of the first guide rail 2 is greater than the hardness of the limb body 1. Because the first guide rail 2 usually needs to slide with the chuck, it is made of a material with higher hardness, which can effectively improve the service life of the limb, that is, improve the service life of the slingshot. Preferably, the material of the first guide rail 2 is a wear-resistant material such as tungsten steel or bearing steel, which is a super-hard wear-resistant material. In actual use, the limb body 1 and the guide rails (i.e., the first guide rail 2 and the second guide rail 3) are processed and manufactured separately, and the guide rails (i.e., the first guide rail 2 and the second guide rail 3) can be set to a material with high hardness and good wear resistance (such as tungsten steel or bearing steel), which not only ensures that the guide rails (i.e., the first guide rail 2 and the second guide rail 3) on the limb have sufficient wear resistance during use, thereby ensuring the service life, but also ensures that the overall cost of the limb is low.
[0036] The specific fixed connection form between the first guide rail 2 and the bow arm body 1 can be, but is not limited to: fixed connection by friction welding.
[0037] The specific fixed connection form between the first guide rail 2 and the limb body 1 can also be, but is not limited to: the first guide rail 2 is detachably fixedly connected to the limb body 1 through the fixing member 4. Among them, a threaded hole 110 is provided on the first mounting portion 11, a through hole 20 is provided on the first guide rail 2, and the fixing member 4 passes through the through hole 20 and is threadedly connected in the threaded hole 110. Specifically, a plurality of threaded holes 110 are arranged side by side on the first mounting portion 11, and a plurality of through holes 20 corresponding to the threaded holes 110 are provided on the first guide rail 2. The plurality of fixing members 4 respectively pass through the plurality of through holes 20 and are threadedly connected in the plurality of threaded holes 110. The plurality of fixing members 4 arranged in sequence fix the first guide rail 2 on the first mounting portion 11 to ensure reliable fixation. The detachable fixing method of the fixing member 4 is adopted, and the replacement of the first guide rail 2 is also convenient. The fixing member 4 preferably adopts a threaded flange bead, and the bead 41 on the flange bead protrudes from the top of the first guide rail 2, the external thread on the flange bead is threadedly connected with the threaded hole 110, the flange 40 on the flange bead presses and fixes the first guide rail 2, and the bead 41 protrudes from the top of the first guide rail 2 to facilitate the sliding of the chuck. In addition to the threaded flange bead, the fixing member 4 can also adopt screws or bolts, which can realize the detachable fixing of the first guide rail 2 on the first mounting portion 11.
[0038] The first guide rail 2 and the bow arm body 1 may also be fixed in other ways, which will not be described in detail here.
[0039] The cross section of the first guide rail 2 of this embodiment is an isosceles trapezoid, with its long side at the top and its short side at the bottom. That is, two inclined surfaces 21 are symmetrically arranged on both sides of the first guide rail 2, and both inclined surfaces 21 gradually tilt inward from top to bottom. The two inclined surfaces 21 can allow the chuck to slide and prevent the chuck from detaching upward from the first guide rail 2.
[0040] Specifically, the limb body 1 of the present embodiment has a second mounting portion 12, and the second mounting portion 12 is symmetrically arranged with the first mounting portion 11, and the symmetrical structure is convenient for processing. In addition, the split limb structure of the present embodiment also includes a second guide rail 3, which is mounted on the second mounting portion 12 and fixedly connected to the limb body 1, and the second guide rail 3 is symmetrically arranged with the first guide rail 2, and the first guide rail 2 and the second guide rail 3 have the same structure.
[0041] It needs to be explained that the specific structure of the second guide rail 3 is exactly the same as that of the first guide rail 2, the installation positions of the two are interchangeable, and the specific fixed connection method between the second guide rail 3 and the bow arm body 1 is also the same as the fixed connection method between the first guide rail 2 and the bow arm body 1, which can ensure that the forces on both sides of the bow arm are balanced when in use.
[0042] In this solution, the bow arm body 1 and the two guide rails (the first guide rail 2 and the second guide rail 3) of the split bow arm can be processed separately, which can effectively improve the processing accuracy of the bow arm, ensure the overall matching precision of the bow arm, and extend the service life of the bow arm.
