Description
Technical field
The present invention relates to bow and arrow technical fields, and in particular to a kind of to be mounted on the bow use that is used to alleviate on bow and shake when shooting
Spring damper.
Background technique
With the increasing living standards of the people, archery activity is gradually general as a kind of effective means taken exercises
And it comes.It is well known that the bow itself pulled open has huge energy, after arrow is shot out, remaining energy can generate vibration,
To be damaged to bow, bowstring and the arm of ejaculator.
For this purpose, bow is come into being with spring damper.If notification number is that CN201892479U Chinese patent discloses one kind
Bow spring damper, includes four decoupling rods and bradyseism part of metal material, wherein decoupling rod includes to be fixed on bow again
On base portion and multiple elastic rods, multiple elastic rod intervals are fixed on base portion, and the other end extends outwardly and becomes free end, together
When multiple decoupling rod be embedded in bradyseism part and become mutually one.In use, vibration is transmitted to bradyseism part by decoupling rod
It above stores and cuts out, to alleviate the vibration of bow and the discomfort of user's arm.But the damper quality structure of the type
It is fixed, there is certain deficiency in terms of the adaptation of different types of bow.For another example U.S. Patent number 4,570,608 disclose a kind of bow
Damper is filled with liquid, includes hollow cylinder and the bradyseism liquid being directly connected to decoupling rod.In addition, in damper
End is equipped with screw thread, the stability that can ensure to bend by the object that screw thread increases different quality.Buffering falls process of shooting an arrow as a result,
The vibration of generation improves the stability of archery.Although the damper of the type, which increases weight by end, realizes the change of quality
It also will increase damper length while changing, but increase weight, be unfavorable for hunting and shoot.And also have to the appearance of damper
It influences.
Summary of the invention
In view of the deficiencies of the prior art, technical problem to be solved by the present invention lies in provide a kind of bow spring shock absorption
Device can effectively realize its shock-absorbing function, while may be implemented that the adjusting of damper quality is convenient to mount and dismount, is expanded again
The scope of application of damper.
In order to solve the above-mentioned technical problem, the technical solution of bow of the invention spring damper is: a kind of bow uses spring
Damper includes the shell in shock-absorbing main bodies and the fixed shock-absorbing main bodies, and the shell is divided into cylindrical housings and funnel-form shell

The cylindrical housings are fixed with outside set and rubber stopper；It is provided in cylindrical housings corresponding with the circular hole of the rubber ring
Hole, for fixing damping spring, described damping spring one end is fixed in the circular hole of rubber ring, and the other end is bolted
In case surface.
As an improvement of the above technical solution, the cylindrical housings surface sets figuratum engraved structure and end as half
Sealing structure with the installation for shock-absorbing main bodies and prevents shock-absorbing main bodies from skidding off.
As an improvement of the above technical solution, the end of the funnel-form shell is provided with connecting column, on the connecting column
It is provided with screw thread, for easily installing and being fixed on the bow handle of bow and arrow.
Further, at least provided with two spindle-type α-Fe2O3s in the middle part of the decoupling rod.
Using the above structure, it is formed in the middle part of spindle-type α-Fe2O3 by opening round-meshed rubber ring, to fix the position of damping spring
It sets.
Further, the circumferential surface of the rubber ring is uniformly provided with multiple circular holes.
Using the above structure, it can be used for fixing one end of damping spring, rubber material can preferably fix damping spring
And vibration energy is transmitted, corresponding place is provided with same size threaded hole at case surface.The other end of damping spring is logical
It crosses the bolt with interior hexagonal cylindrical end to be fixed, to realize that the fixation of damping spring and shock-absorbing function play.
Preferably, one end of the decoupling rod is formed with two small circle ring protrusions for fixing the shock-absorption rubber sleeve,
Prevent the sliding of shock-absorption rubber sleeve.
Using the above structure, rubber ring is fixed among shell, thus fixed decoupling rod.
Preferably, the yielding rubber, which is put on, is provided with multiple buffering circular holes.
Using the above structure, the damping effect of damper can be further enhanced.
As an improvement of the above technical solution, there is annulus on the outside of the rubber stopper, corresponding interior of shell has groove,
For realizing the sealing of fixation and damper to decoupling rod.
Preferably, the damping spring is compressed spring；The damping spring is by import piano wire, oil hardening tempered steel
Silk, rubber or silica gel are made.
Using the above structure, using compressed spring, when vibration energy is transmitted to spring by decoupling rod, compressed spring energy
Energy is preferably absorbed, realizes shock-absorbing function.These materials of damping spring have good compression performance, and shock-absorbing effect is good.
Preferably, the decoupling rod is made of plastics, aluminium alloy, carbon fibre composite or glass fiber compound material.
It is more suitable for the transmitting of vibration using above-mentioned material, in practical shooting course, facilitating will be on bow handle and bowstring
Vibration energy is transferred to damping spring and yielding rubber is absorbed and discharged.
Compared with prior art, bow of the invention is carried out with the decoupling rod in spring damper by the yielding rubber at both ends
It fixes, it can be achieved that effectively absorbing and releasing to vibration energy, the spring connected between decoupling rod and shell is conducive to damping
Device is to each absorption to vibration energy and is released in air, strengthens the shock-absorbing function of damper, to reduce shooting course
Middle vibration injures sharpshooter and bow.In addition, the stability and hit rate of shooting can also be improved.
