Technical Field

The invention relates to the technical field of sports apparatuses, in particular to a kinking sports apparatus with a protection device.

Background

Among various existing sports apparatuses, there are many sports forms that have been launched, controlled and hit by operating the bending elasticity of the sports apparatus, taking bow shooting as an example, the bow and arrow shown in fig. 6 mainly uses a bow piece a with two ends connected with two ends of a bowstring B, the bow piece a is generally made of a material with bending toughness of bending, so that when the bowstring B pulls the two ends of the bow piece a, the bow piece a is bent through the bending to form elasticity to launch the bow and arrow; the bow sheet A is generally made of multiple layers of bamboo sheets or wood sheets with tough fibers, and can generate elasticity for archery when being bent and kinked by means of arrangement fibers formed by the growth of the bamboo sheets and the wood sheets.

FIG. 7 is a schematic sectional view showing the aforementioned change in bending under force required for a bow A having aligned fibers A1, wherein the upper view shows that the bow A is subjected to a tensile force different from the growth direction of the fibers A1 under frequent kinking bending operations, and a torn crack A2 (shown in FIG. 7) is easily formed from the gap between the aligned fibers A1; further, if the crack a2 formed in the blade a is used without reinforcement, the crack a2 is gradually deepened (as shown in the lower part of fig. 7), and the blade a is broken and cannot be used.

The main technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art, and provide a kinking sports apparatus with a protection device, wherein the kinking sports apparatus has an elastic tension capable of deforming along with the surface bending of the kinking sports sheet by attaching a combined tension cladding layer structure on the outer surface of the kinking sports sheet, and can absorb the shock formed by kinking to improve the use stability, and can protect the surface structure of the kinking sports sheet from breaking, so as to maintain the durability of operation and use.

The technical scheme adopted by the invention for solving the technical problems is as follows:
