Description

Technical Field

[0001] The utility model relates to the technical field of bow and arrow accessories, in particular to a rifling particle damping device. Background Art

[0002] The bow and arrow is a composite long-range weapon, consisting of two independent parts, the bow and the arrow. When a compound bow is pulled, the limbs of the bow body will bend inward, and the user transfers the force of pulling the bow to the limbs, and the deformation of the limbs converts the kinetic energy of the user's bow pulling into the potential energy of the limb deformation. When the bowstring is released, the potential energy stored in the limbs is transferred to the arrow through the displacement of the bowstring, and converted into the kinetic energy of the arrow during flight. However, the arrow cannot take away all the kinetic energy on the bow body. The redundant kinetic energy will remain on the limbs, causing the bow body to vibrate and sway, and then be transferred to the user's hand, affecting the stability of the hand.

[0003] Then, the user installs a shock absorber tank at the end of the balance bar, and the shock absorber tank is filled with a single tungsten steel powder. The balance bar transmits the vibration of the bow body to the shock absorber tank, and the tungsten steel powder hits the inner wall of the internal cavity of the shock absorber tank to release the vibration, thereby reducing the vibration of the bow body.

[0004] However, the following technical problems still exist: the radius of the shock absorber tank cavity is large, and the interior of the cavity does not have components for limiting the tungsten steel powder, resulting in a long displacement stroke of the tungsten steel powder in the cavity, causing the tip of the balance rod to move back and forth in the vertical direction with a large amplitude, and the vibration release effect and frequency are very limited, resulting in a poor user experience.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] like Figure 1-4 As shown, the utility model provides a rifling particle shock-absorbing device, including a shock-absorbing device body 1, the shock-absorbing device body 1 has an annular closed shock-absorbing cavity 2, the shock-absorbing cavity 2 is filled with shock-absorbing particles, the shock-absorbing cavity 2 is provided with a plurality of reinforcing ribs 3, the reinforcing ribs 3 divide the shock-absorbing cavity 2 into shock-absorbing cavity 2 chambers, and two adjacent shock-absorbing cavity 2 chambers are interconnected to limit the displacement stroke of the shock-absorbing particles in the shock-absorbing cavity 2.

[0027] The utility model separates the shock absorbing cavity 2 into a shock absorbing cavity 2 chamber by reinforcing ribs 3, which can effectively limit the displacement stroke of the shock absorbing particles in the shock absorbing cavity 2, so that the shock absorbing particles and the shock absorbing particles, the shock absorbing particles and the reinforcing ribs 3, and the shock absorbing particles and the inner wall of the shock absorbing cavity 2 can fully rub and collide, so as to realize multi-dimensional vibration to absorb and consume vibration energy, play an excellent shock absorbing effect, and improve the comfort of use. In addition, the setting of the reinforcing ribs 3 improves the structural strength of the shock absorbing device body 1 to a certain extent, and prolongs the service life.

[0028] As an optional implementation, Figure 2 , 3As shown, the reinforcing ribs 3 are arranged along the circumference of the shock absorbing cavity 2 and extend along the radial direction of the shock absorbing cavity 2. The number of reinforcing ribs 3 can be designed according to usage requirements.

[0029] The shock absorbing cavity 2 is divided into shock absorbing cavity 2 chambers by reinforcing ribs 3 to limit the displacement stroke of the shock absorbing particles in the shock absorbing cavity 2, especially to limit the movement amplitude of the shock absorbing particles in the vertical direction, so that the shock absorbing particles and the shock absorbing particles, between the shock absorbing particles and the reinforcing ribs 3, and between the shock absorbing particles and the inner wall of the shock absorbing cavity 2 can fully rub and collide, so as to realize multi-dimensional vibration to absorb and consume vibration energy, especially enhance the absorption of vibration perpendicular to the ground, the vibration decays faster, and has an excellent shock absorbing effect.

[0030] As an optional implementation, Figure 2 , 3 As shown, two adjacent reinforcing ribs 3 are staggeredly arranged along the axial direction parallel to the shock absorbing device body 1. The number of layers of the reinforcing ribs 3 can be designed according to the use requirements.

[0031] As an optional embodiment, the damping particles include at least lead particles and tungsten particles.

[0032] Furthermore, the lead particles are preferably lead balls, and the tungsten particles are preferably tungsten steel particles.

[0033] Compared with the prior art that uses particles of a single material for shock absorption, the shock-absorbing particles of the utility model include at least lead particles and tungsten particles. The lead particles are soft and ductile, and the tungsten particles have high hardness. The lead particles are frequently rubbed and collided with the tungsten particles, the reinforcing ribs 3, and the inner wall of the shock-absorbing cavity 2, and the force generated causes the lead particles to deform, further absorbing aftershocks. The shock absorption effect is excellent, and aftershocks can be effectively reduced.

[0034] As an optional embodiment, the shock-absorbing particles further include weighting particles for increasing weight.

[0035] By filling the shock absorbing cavity 2 with weight-increasing particles, the weight of the shock absorbing device body 1 is increased, replacing the counterweight block in the prior art, reducing the number of bow assembly parts, and effectively simplifying the structure. Among them, the weight-increasing particles are prior art and will not be described in detail here.

[0036] As an optional implementation, Figure 1 , 2 As shown in 3, a threaded section 4 is provided on the outer wall of the shock absorbing chamber 2 near the center of the circle, and the threaded section 4 passes through the shock absorbing device body 1. The first end of the threaded section 4 is threadedly connected to the balance rod, and the second end of the threaded section 4 is threadedly connected to the closed plug 6.

[0037] Furthermore, the first end of the threaded segment 4 is threadedly connected to the connection hole of the balance bar through the screw, and the second end of the threaded segment 4 is threadedly connected to the connection hole of the closed plug 6 through the screw. Through the threaded matching method, the assembly and disassembly of the shock absorbing device body 1 and the balance bar and the closed plug 6 are realized efficiently and quickly. Among them, the specific structure of the threaded matching of the shock absorbing device body 1 and the balance bar and the closed plug 6 is the existing technology, and no further description is given here.

[0038] like Figure 4 As shown, when the bow body needs to be placed on the ground, the closed plug 6 is assembled to the shock absorbing device body 1 through a screw, that is, the closed plug 6 is in direct contact with the ground, avoiding direct contact between the shock absorbing device body 1 and the ground, thereby extending the service life of the shock absorbing device body 1.

[0039] As an optional implementation, a plurality of friction structures are provided on the outer peripheral wall of the shock absorbing device body 1 . The friction structures are arranged in sequence along the circumference of the shock absorbing device body 1 and extend in an axial direction parallel to the shock absorbing device body 1 .

[0040] The function of the friction structure is to increase the friction force of the outer peripheral wall of the shock absorbing device body 1, thereby preventing the user from slipping when assembling the shock absorbing device body 1 by hand, greatly improving the connection tightness, and facilitating the bare-hand assembly or disassembly of the shock absorbing device body 1.

[0041] As an optional embodiment, the friction structure includes protrusions or grooves 5 .

[0042] Further, such as Figure 1-4 As shown, the friction structure preferably adopts grooves 5, which are arranged in sequence along the circumferential direction of the shock absorbing device body 1 and extend in parallel with the axial direction of the shock absorbing device body 1. The grooves 5 can increase the friction force of the outer peripheral wall of the shock absorbing device body 1, avoid the problem of slipping when the user assembles the shock absorbing device body 1 by hand, greatly improve the connection tightness, and facilitate the assembly or disassembly of the shock absorbing device body 1 by hand.
