Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of bows and arrows, and in particular to a bow limb locking and fixing structure. Background technology:
[0002] Currently, in the structure of a compound bow, one end of the limb is used to install the bowstring, and the other end of the limb is fixed to the limb holder. When shooting, the bowstring will cause one end of the limb to vibrate. However, since the connection between the limb and the limb holder is not strong enough, the limb itself will shake slightly during each vibration, which will have a certain impact on the shooting accuracy. At present, there is no good way to solve the above problem.
[0003] In summary, how to achieve locking and fixation between the bow limbs and the limb holders has become a technical problem that urgently needs to be solved in the industry. Utility model content:
[0004] In order to make up for the deficiencies of the prior art, the utility model provides a limb locking and fixing structure, which solves the problems that the connection between the limb and the limb seat is not firm enough, the limb shakes, and the shooting accuracy is affected.
[0005] The technical solution adopted by the present invention to solve the above technical problems is:
[0006] A bow limb locking and fixing structure includes a bow limb and a limb seat, one side of the end of the bow limb is tightly mounted on the limb seat, and the other side is tightly mounted on the fixing seat, the limb seat, the bow limb and the fixing seat are connected and fixed by locking bolts, and limit blocks are respectively provided on both sides of the fixing seat, and a slot that closely fits the bow limb is formed between the two limit blocks. The bow limb is installed in the slot, and the two limit blocks are used to limit the left and right shaking of the end of the bow limb.
[0007] The piece seat and the bow piece are respectively provided with through holes, the fixing seat is provided with threaded holes, and the locking bolts pass through the through holes on the piece seat and the bow piece in sequence and are threadedly connected with the threaded holes on the fixing seat.
[0008] A threaded boss is provided on the fixing seat at a position corresponding to the threaded hole, and the threaded boss is inserted into the through hole of the bow piece.
[0009] The position of the bow limb close to the end is clamped and fixed between the clamping block and the limb seat.
[0010] A pull rod is installed on the piece seat, and both ends of the pull rod extend to the lower side of the bow piece respectively. A threaded hole is provided on the inner side of the end of the pull rod, and a clamping block is inserted on the outer side of the end of the pull rod. The screw passes through the clamping block and is threadedly connected to the threaded hole of the end of the pull rod. The clamping block is provided with a lug, which clamps the bow piece and the piece seat.
[0011] A gasket is provided between the side of the bow piece away from the lug and the piece seat.
[0012] The gasket is made of plastic or rubber.
[0013] The utility model adopts the above solution and has the following advantages:
[0014] The end of the bow limb is fixed to the limb seat by setting a fixing seat, and limit blocks are provided on both sides of the fixing seat. The two limit blocks can limit the left and right shaking of the end of the bow limb. When the bowstring drives one end of the bow limb to vibrate, the other end of the bow limb will not shake left and right under the limiting action of the two limit blocks. In addition, the position of the bow limb near the end is clamped and fixed between the clamping block and the limb seat. After the screws are tightened, the lugs on the clamping block can clamp the bow limb and the limb seat, which can also prevent the bow limb from shaking left and right. After the fixing seat and the clamping block cooperate, a double locking and fastening between the bow limb and the limb seat can be formed, thereby improving shooting accuracy.

[0021] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0022] like Figure 1-5 As shown, a bow limb locking and fixing structure includes a bow limb 1 and a limb seat 2. One side of the end of the bow limb 1 is tightly mounted on the limb seat 2, and the other side is tightly mounted on the fixing seat 3. The limb seat 2, the bow limb 1, and the fixing seat 3 are connected and fixed by a locking bolt 4. Limit blocks 5 are respectively provided on both sides of the fixing seat 3. A slot 6 that fits tightly with the bow limb 1 is formed between the two limit blocks 5. The bow limb 1 is installed in the slot 6. The two limit blocks 5 are used to limit the left and right shaking of the end of the bow limb 1.
[0023] The plate seat 2 and the bow limb 1 are respectively provided with through holes, and the fixing seat 3 is provided with a threaded hole 7. The locking bolt 4 passes through the through holes on the plate seat 2 and the bow limb 1 in sequence and is threadedly connected with the threaded hole 7 on the fixing seat 3. The locking bolt 4 locks and fixes the plate seat 2, the bow limb 1 and the fixing seat 3 in the upper and lower directions.
[0024] A threaded boss 8 is provided on the fixing seat 3 at a position corresponding to the threaded hole 7. The threaded boss 8 is inserted into the through hole of the limb 1. The threaded boss 8 can increase the length of the threaded hole 7, thereby improving the pulling force of the threaded connection between the locking bolt 4 and the fixing seat 3 and increasing the connection strength.
[0025] The position of the limb 1 near the end is clamped and fixed between the clamping block 9 and the limb seat 2, and the clamping block 9 can also limit the left and right shaking of the limb 1.
[0026] A pull rod 10 is installed on the piece seat 2, and the two ends of the pull rod 10 extend to the lower side of the bow piece 1 respectively. A threaded hole is provided on the inner side of the end of the pull rod 10, and a clamping block 9 is inserted on the outer side of the end of the pull rod 10. The screw passes through the clamping block 9 and is threadedly connected to the threaded hole at the end of the pull rod 10. A lug 11 is provided on the clamping block 9. By screwing the screw, the lug 11 can clamp the bow piece 1 and the piece seat 2.
[0027] A gasket 12 is provided between the side of the limb 1 away from the lug 11 and the limb seat 2. The gasket 12 is made of plastic or rubber and can eliminate gaps as much as possible, so that the limb 1 is clamped more firmly between the clamping block 9 and the limb seat 2.
[0028] Working principle:
[0029] When installing the fixing base 3, after the limb base 2, limb 1, and fixing base 3 are stacked, the limb 1 is installed in the slot 6 of the fixing base 3, so that the through holes and threaded holes 7 on the limb base 2, limb 1, and fixing base 3 are aligned. Then, the locking bolt 4 is passed through the through holes on the limb base 2 and limb 1 in sequence and is threadedly connected to the threaded hole 7 on the fixing base 3. By tightening the locking bolt 4, the fixing base 3 and the limb base 2 clamp the limb 1 in the vertical direction. The limb 1 is restricted in the left and right directions by the limit blocks 5 on both sides of the fixing base 3 to prevent the limb 1 from shaking. When installing the clamping block, first pass the pull rod 10 through the limb base 2, then put the two clamping blocks 9 on the outside of the ends of the pull rod 10 respectively, and then screw through the clamping blocks 9 and screw into the threaded holes at the ends of the pull rod 10. By tightening the screw, the lugs 11 on the clamping blocks 9 can cooperate with the limb base 2 to clamp the limb 1 in the left and right direction, preventing the limb 1 from shaking, thereby improving shooting accuracy.
[0030] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.
[0031] Anything not described in detail in the present invention is well known to those skilled in the art.
