Abstract

The utility model relates to a damper for bows. The damper is characterized in that: the damper comprises a damping rod made of metal and a cushioning part made of vibration-absorbing material, wherein the damping rod comprises a basal part fixed on a bow and a plurality of elastic rods, one end of each elastic rod is respectively fixed on the basal part at intervals, the other ends of the elastic rods are extended outwards to form free ends, and meanwhile, the elastic rods are embedded in the cushioning part, so that an integrated part is formed. When the damper is in use, the vibrating energy generated by the bow can be stored on the damping rod, and after the damping rod absorbs part of the vibrating energy, and the rest of the vibrating energy is diminished by the cushioning part made of vibration-absorbing material. Furthermore, by means of damping sheets on the cushioning part, the damper has extra cushioning capability. Consequently, the damper can effectively damp the vibration of the bow, the accuracy of shooting is increased, the discomfortable feeling of a shooter is relieved, meanwhile, the service lives of the bow and a bowstring can be prolonged, and the damper provides inertial stability for the combination of the bow and the bowstring.

Description

The bow damper
Technical field
The utility model relates to a kind of damper, specifically refers to a kind of bow damper that bow is gone up, vibrated when being used for alleviating shooting that is installed in.
Background technology
When arrow penetrated from bending, bow will produce vibration, and this vibration both can influence the accuracy of shooting, and can wear and tear again bow and bowstring also can damage ejaculator's hand and arm simultaneously.For this reason, people design bow and come with damper, as Chinese patent Granted publication number for " the bow and crossbow support damper " of CN2396368Y just disclosed so a kind of device, it comprises the telescopic support bar that is formed by connecting by not isometrical sleeve pipe and is located at the support bar supporting leg at two ends and the attaching parts that are connected with bow and crossbow up and down, be flexible clamping between its two sleeve pipe, supporting leg, be used for the attaching parts that are connected with bow and crossbow respectively and can adopt flexible clamping or affixed mode between telescopic supporting rod.After adopting such device, the vibration that the percussion of bow body produces in the time of bow being shot is directly transferred to ground by this device, thereby can reduce trembling that sharpshooter's arm brings, and has improved the stability and the hit rate of shooting.Can also alleviate simultaneously the arm supporting power of ejaculator when shooting an arrow to a certain extent.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of novel structure is provided, and can alleviate the bow damper of the vibration that produces when bow is shot equally.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this bow includes the decoupling rod of metal material and the bradyseism part of shock-absorbing material with damper, wherein decoupling rod includes base portion and a plurality of elastic rod that is fixed on the bow again, one end of a plurality of elastic rods compartment of terrain respectively is fixed in described base portion, the other end stretches out and becomes free end, and these a plurality of elastic rods are embedded in described bradyseism part and become integral piece mutually simultaneously.
The optimal process ground that is connected between bradyseism part and the elastic rod adopts Shooting Technique, at this moment, the bradyseism part can adopt thermoplastic elastomer (TPE) (TPE) or rubber material, simultaneously, on described a plurality of elastic rods, can have a plurality of apertures in order to improve the fastness that combines between elastic rod and the bradyseism part.
In above-mentioned each scheme, described bradyseism part can be designed to column structure, extends a plurality of vibration damping sheets on the radial circumference direction of this cylinder of the surperficial upper edge of this cylinder radially, to play better bradyseism ability.
For the convenience of installing, described base portion can have the base station of double-screw bolt for an end, and nut is threaded on the described double-screw bolt.When this damper is installed to bow when going up, as long as double-screw bolt is threaded onto in the screw on the bow, and the rotation nut location that can realize damper easily to screwing state.
Preferably, described elastic rod can have four, respectively along circumferentially being fixed on equably on the described base station.Under the simple relatively condition of structure, to obtain damping effect preferably.
Compared with prior art, because bradyseism part of the present utility model closely is connected with decoupling rod, and have only again by base portion and be fixed on the bow, thereby can produce resonance with bow after the shooting, bow is gone up the vibrational energy that produces to be stored on the decoupling rod, after decoupling rod absorbed a part of vibrational energy, remaining vibrational energy was then cut out by the bradyseism part that vibration absorptive material is made.Moreover, by means of the vibration damping sheet on the bradyseism part, make the extra bradyseism ability that the utlity model has.So the utility model can be alleviated the vibration of bow effectively, the accuracy when increasing shooting alleviates ejaculator's sticky feeling, can prolong the service life of bow chord simultaneously.In addition, the utility model also provides the stable of an inertia for the combination of bow chord.

Fig. 3 is the three-dimensional cutaway view of Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, this bow includes decoupling rod 1 and bradyseism part 2 with damper, wherein decoupling rod 1 usefulness steel process, it includes base portion 3 and a plurality of elastic rod 4 that is fixed on the bow, in the present embodiment, base portion is the base station 32 that an end has double-screw bolt 31, and nut 5 is threaded on the double-screw bolt 31; Elastic rod 4 designs have four, and an end is fixedly welded on the base station 32 respectively evenly and at intervals, and the other end stretches out and becomes free end.
Above-mentioned bradyseism part 2 adopts and is made with thermoplastic elastomer (TPE) (TPE) or rubber, and it is designed to column structure, extends a plurality of vibration damping sheets 21 on the radial circumference direction of this cylinder of the surperficial upper edge of this cylinder radially.
In the present embodiment, above-mentioned decoupling rod 1 closely links to each other with bradyseism part 2, and the connected mode between them is as follows: make the bradyseism part be coated on the outside of four elastic rods 4 and base station 32 with Shooting Technique.Being about to four elastic rods 4 makes decoupling rod 1 and bradyseism part 2 become integral piece mutually as the inserts injection moulding.
For decoupling rod and bradyseism part are linked into an integrated entity more closely, on above-mentioned each elastic rod, have a plurality of apertures 41, during injection moulding, thermoplastic elastomer (TPE) (TPE) or rubber just are filled in this aperture like this, with improve both in conjunction with firmness.
During installation, decoupling rod is to be threaded in the screw on the bow by double-screw bolt, and screws the location with nut.
When fire produces, on bow and bowstring, produce vibration thereupon, the vibrational energy on the bow just is delivered on the elastic rod by the base portion of decoupling rod, is delivered at last on the bradyseism part, owing to decoupling rod is with the steel making, can be used for absorbing vibrational energy.The bradyseism part is to make of TPE (thermoplastic elastomer (TPE)) or rubber, this material has the ability that absorbs vibrational energy, and it is fixed on the elastic rod, and the other end of elastic rod is a free end, so concerning the bradyseism part, it does not just need to adjust and can be associated with the vibrational energy of different frequency scope, thereby makes vibrational energy be impaired to minimum by the bradyseism part.Be that bradyseism part in the present embodiment can be used for eliminating vibrational energy.Utilize the extra bradyseism ability that vibration damping sheet provided on the bradyseism part simultaneously, further will bend the vibrational energy that is produced and weaken dissipation.
