Description

Technical Field

[0001] This utility model relates to the field of simulated bow technology, and in particular to an adjustable draw length structure for simulated bows. Background Technology

[0002] With the widespread development of archery, simulated bows, as important training and recreational tools, are increasingly popular. However, traditional simulated bows have significant shortcomings in terms of draw length adjustment. The draw length of existing simulated bows is usually fixed, making it difficult to adapt to the different body differences of different trainees and to help them find a comfortable point of force application. Since different trainees have different arm spans, for people with longer arm spans, a simulated bow with a fixed draw length may prevent them from fully extending their arms when drawing the bow, making it difficult to exert power and affecting the accuracy and range of the arrow. On the other hand, people with shorter arm spans may feel strained due to an excessive draw length and be unable to maintain a stable drawing posture. Long-term use may also cause physical fatigue or even injury. Therefore, an adjustable draw length structure for simulated bows is proposed to address the above problems. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] The simulated bow has an adjustable draw length structure, including a bow limb. One end of the bow limb is provided with a bowstring, and the end of the bowstring is tied to one end of the bow limb. The other end of the bow limb contacts a bow handle. Both ends of the bow handle have cuboid-shaped connecting blocks that are slidably positioned on the inner side. One end of the inner side of each connecting block is screwed with a threaded shaft, which passes through the connecting block and the bow handle. The threaded shaft is rotatably connected to the bow handle. The right end of the outer side of the bow handle is provided with a handle sleeve, which is fixedly connected to the bow handle.

[0006] As a further improvement of this utility model, the bow handle is U-shaped, and the bow plates are symmetrically arranged on the outside of the bow handle.

[0007] As a further improvement of this utility model, a limiting groove is provided on the outer side of the other end of the bow piece, and one end of the connecting block is limited in the limiting groove at one end of the bow piece. The other end of the inner side of the connecting block is spirally connected with a bolt, and the bolt passes through the bow piece. The bolt is spirally connected to the bow piece.

[0008] As a further improvement of this utility model, a sprocket is fixedly connected to the right end of the outer side of the threaded shaft, and a chain is engaged with the outer side of the sprocket. The thread direction of the front threaded shaft is the same as the thread direction of the rear threaded shaft.

[0009] As a further improvement of this utility model, an indicator block is fixedly connected to one end of the outer side of the connecting block, and the indicator block passes through the bow handle. The indicator block is in contact with the bow handle, and a scale is provided at the bottom of one end of the outer side of the indicator block, and the scale is fixedly connected to the bow handle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] By rotating the threaded shaft and connecting it to the connecting block, the connecting block further drives the bow limbs connected to the bowstring to move left and right along the bow handle. According to the different arm spans of some trainees, the distance between the handle and the bowstring can be adjusted within a certain range. In this way, during simulated bow training, the draw length of the simulated bow can be adjusted within a certain range. This can solve the problems of long arm spans making it difficult to exert power, affecting the accuracy and range of archery, and short arm spans making it difficult to maintain a stable drawing posture, which may cause physical fatigue or even injury. It makes it easier for trainees to find a comfortable point of force. Attached Figure Description

[0019] Example 1

[0020] like Figure 1-4 As shown, the adjustable draw length structure of the simulated bow includes a bow piece 1. One end of the bow piece 1 is provided with a bow string 2, and the end of the bow string 2 is tied to one end of the bow piece 1. The other end of the bow piece 1 contacts a bow handle 3. Both the front and rear ends of the inner side of the bow handle 3 are limited and slidably provided with cuboid-shaped connecting blocks 4. One end of the inner side of the connecting block 4 is screwed with a threaded shaft 6, and the threaded shaft 6 passes through the connecting block 4 and the bow handle 3. The threaded shaft 6 is rotatably connected to the bow handle 3. The right end of the outer side of the bow handle 3 is provided with a handle sleeve 11, and the handle sleeve 11 is fixedly connected to the bow handle 3.

[0021] Furthermore, such as Figure 1-3 As shown, the bow handle 3 is U-shaped, and the bow plates 1 are symmetrically arranged on the outside of the bow handle 3. By making the bow handle 3 U-shaped and the bow plates 1 symmetrically distributed on the outside of the bow handle 3, the draw distance of the device can be easily adjusted within a certain range when the bow plates 1 are controlled to move left and right on the outside of the bow handle 3.

[0022] Furthermore, such as Figure 1-4 As shown, a limiting groove is provided on the outer side of the other end of the bow piece 1, and one end of the connecting block 4 is limited in the limiting groove at one end of the bow piece 1. The other end of the inner side of the connecting block 4 is spirally connected with a bolt 5, and the bolt 5 passes through the bow piece 1. The bolt 5 is spirally connected to the bow piece 1. By making one end of the bow piece 1 stuck on the outer side of the connecting block 4 and then fixed by the bolt 5, it is convenient to connect the bow piece 1 to the outer side of the bow handle 3.

[0023] Furthermore, such as Figure 3As shown, a sprocket 7 is fixedly connected to the right end of the outer side of the threaded shaft 6. A chain 8 is meshed with the outer side of the sprocket 7. The thread direction of the front threaded shaft 6 is the same as that of the rear threaded shaft 6. By rotating one side of the threaded shaft 6, the sprocket 7 on one side is driven to mesh with the chain 8. Furthermore, when the chain 8 meshes with the sprocket 7 on the other side, it drives the threaded shaft 6 on the other side to rotate. This facilitates stable control of the front and rear threaded shafts 6 and the corresponding connecting blocks 4 for spiral connection. In turn, when the connecting blocks 4 drive the bow piece 1 to move outside the bow handle 3 to adjust the draw length, the stability of the adjustment operation is ensured.

[0024] Furthermore, such as Figure 1-3 As shown, an indicator block 9 is fixedly connected to one end of the outer side of the connecting block 4, and the indicator block 9 passes through the bow handle 3. The indicator block 9 is in contact with the bow handle 3. A scale 10 is provided at the bottom of one end of the outer side of the indicator block 9, and the scale 10 is fixedly connected to the bow handle 3. During the process of adjusting the draw distance by moving the indicator block 9 and moving the bow piece 1 on the outside of the bow handle 3, since different people may adjust the device again when operating the device later, after the adjustment is completed, by remembering the scale on the scale 10 where the indicator block 9 is pointed by the connecting block 4, it is convenient to quickly find a comfortable point of force when training again.

[0025] The draw length adjustment principle of the simulated bow: The two threaded shafts 6 are manually connected to the corresponding connecting blocks 4 via the engagement of the sprocket 7 and chain 8. At this time, the connecting block 4 will move the indicator block 9, simultaneously causing the bow limb 1, connected to the bowstring 2, to move left and right along the bow handle 3. Since a single adjustment is insufficient to quickly reach a comfortable draw length, the device must be operated after each adjustment until a comfortable draw length is achieved. Training can then proceed. Because different people may adjust the device again later, after adjustment, it is necessary to remember the mark on the scale 10 where the indicator block 9 is positioned by the connecting block 4, so that a comfortable draw length can be quickly found during subsequent training.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
