Examples

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural view of an inflected bow V seat 100 according to the present embodiment, and fig. 2 is a schematic structural view of a penetrating column 160 according to the present embodiment. The recurve bow V seat 100 comprises a V seat main body 110 and a penetrating column 160, wherein the V seat main body 110 comprises a central cylinder 112 and two connecting cylinders 130, the two connecting cylinders 130 are symmetrically arranged along the axial section of the central cylinder 112, moreover, the penetrating column 160 arranged in the central cylinder 112 comprises an exposed part 162, an embedded part 164 and an extending part 166 which are sequentially connected, the exposed part 162 and the embedded part 164 are used for connecting a main rod, and the extending part 166 is used for connecting an extension rod. The anti-bow V seat 100 that so sets up not only self performance is better, can also make balancing pole mobile jib, vice pole and extension rod zonulae occludens to promote the stability and the precision of anti-bow, the practicality is stronger.

As shown in fig. 2, in the present embodiment, the exposed portion 162 and the embedding portion 164 of the through column 160 are provided with communicating threaded grooves 168, and the threaded grooves 168 can match the thread type of the distal end of the main rod of the balance bar, thereby improving the applicability of the recurve bow V-shaped seat 100. Moreover, the screw groove 168 for connecting the main rod is provided in the exposed portion 162 and the embedded portion 164, so that a larger portion of the screw groove 168 is located in the central cylinder 112, when the balance rod main rod is screwed into the screw groove 168, not only the tightening force can be shared by the V-seat body 110, but also the tightening force is not concentrated on the contact position of the exposed portion 162 and the main rod, thereby effectively prolonging the service life of the penetrating post 160 and having a high use value. As shown in fig. 3, fig. 3 is a schematic cross-sectional view of the recurve bow V-shaped seat 100 provided in this embodiment, the extension portion 166 extends from inside of the central cylinder 112 to outside of the central cylinder 112, so that the penetrating column 160 can tightly connect the main rod and the extension rod of the balance rod, and the extension portion 166 remaining inside of the central cylinder 112 can also share the stress applied to the outside of the extension portion 166 to the V-shaped seat main body 110, thereby effectively reducing the stress applied to the extension portion 166, and avoiding the stress from concentrating on a certain position of the extension portion 166 to cause the damage, fracture or falling off of the extension portion 166 from the penetrating column 160, so that the performance and tensile strength of the recurve bow V-shaped seat 100 are improved, and the use value is high. In this embodiment, the exposed portion 162, the embedded portion 164 and the extending portion 166 are coaxially arranged in a cylindrical structure, and the cross-sectional diameters thereof decrease in sequence, as shown in fig. 2. Specifically, the diameter of the exposed portion 162 is 20mm, the diameter of the embedded portion 164 is 14mm, and the diameter of the extending portion 166 is 8mm, so that the diameters of the three portions of the penetrating column 160 are gradually decreased, and the strength of the penetrating column 160 is good, and the using effect is good. The penetrating column 160 in the conventional recurve bow V-shaped seat 100 is suddenly reduced to 8mm from 20mm, the stress is easily concentrated at the position where the diameter is suddenly reduced, and the strength is poor, so that the penetrating column 160 provided by the embodiment can effectively solve the problem, and the performance of the penetrating column 160 is improved. As can be seen from the above, in the present embodiment, the penetrating column 160 is a part of the exposed part 162 and the extending part 166 extending to the outside of the central cylinder 112, and the rest part is hidden in the central cylinder 112, so that the V-seat main body 110 can share the stress applied to the penetrating column 160, the strength of the penetrating column 160 can be enhanced, the performance of the recurve bow V-seat 100 is improved, and the using effect is better. Moreover, the size of the exposed part 162 is reduced, the influence of wind resistance on a user can be effectively reduced, namely, the influence of wind on the archer and the recurve bow in a wind measuring state is reduced, and therefore the precision of the archer and the stability of the recurve bow can be improved. In addition, the matching arrangement of the penetrating column 160 and the central cylinder 112 can ensure that the total length of the installed balance bar is not too long, which affects the accuracy and stability of the recurve bow, and similarly, because the volume of the exposed part 162 is far smaller than that of the traditional recurve bow V seat 100, the strength is improved, the integral feeling between the penetrating column 160 and the V seat main body 110 can be improved, the appearance is more attractive, and the requirements of consumers are met.

Specifically, this gasket 180 is annular gasket 180, and the inside and outside diameter of annular gasket 180 sets up the same with portion 164 and the portion 162 diameter that exposes of inlaying respectively (the outside diameter and the inside diameter of annular gasket 180 are 19mm and 14mm respectively), and its thickness is highly unanimous with the clearance, so can be so that to run through post 160 comparatively stable when using, avoid appearing running through post 160 wobbling phenomenon, thereby make the balancing pole take place to swing or remove, reduce user's experience and feel. Moreover, in this embodiment, the two ends of the gasket 180 are respectively abutted against the upper end of the central cylinder 112 and the lower end of the exposed part 162, so that when the penetrating column 160 is connected with the main rod of the balancing pole and the extension rod, the annular gasket 180 and the central cylinder 112 are both subjected to opposite pressure of the main rod and the extension rod, so that the penetrating column 160, the gasket 180 and the V-seat main body 110 can be tightly connected, the phenomenon that the loosening occurs due to repeated vibration caused by arrow shooting is not easy to occur, the safety factor is high, the use is convenient, and the practicability is high. In this embodiment, the gasket 180 is made of brass in view of the physical properties of brass. Specifically, brass has good hardness, and is not easily deformed when being subjected to positive pressure transmitted by the balance bar, and the brass can be better attached to the central cylinder 112 and the exposed part 162, so that the stability is stronger. In addition, because brass has lower hardness than titanium alloy, the gasket 180 is less damaged by the penetrating column 160 and the central cylinder 112, and the service life is longer, so that the cost performance of the gasket 180 is higher, and the gasket is more suitable for the requirements of consumers.

The large diameter portion of the stepped hole 114 is adapted to the embedded portion 164, and the small diameter portion thereof is adapted to the extending portion 166, so that the through post 160 and the central cylinder 112 are more stably engaged, thereby improving the stability of the recurved bow V-seat 100. Moreover, as shown in fig. 3, a distance is left between the diameter change position of the stepped hole 114 and the connection position of the embedding portion 164 and the extending portion 166, instead of the mutual abutting arrangement, so that the stress can be further dispersed on the central cylinder 112 and the penetrating column 160, and the problem that the stress is concentrated on the diameter reduction part is effectively solved, thereby achieving the effect of improving the performance and strength of the recurve bow V seat 100, and having high use value and practical value. It should be noted that, a distance is also left between the bottom end of the threaded recess 168 and the connection between the embedded portion 164 and the extending portion 166, so as to prevent the tightening force for tightening the main rod and the extending rod from concentrating on the connection position of the embedded portion 164 and the extending portion 166, thereby avoiding the phenomenon that the penetrating post 160 is easily damaged or broken, and achieving better performance. It should be noted that, in the embodiment, in view of the advantages of the titanium alloy, such as higher strength, lower density, better corrosion resistance, etc., the V seat main body 110 and the penetrating column 160 are made of the titanium alloy, which not only makes the anti-bending V seat 100 have better tensile strength and lighter weight, but also makes the use performance not affected by harsh environment, for example, after the anti-bending V seat 100 is stored in a humid environment, the anti-bending V seat 100 will not rust due to humidity, etc., and has higher use value and stronger practicability. In this embodiment, the V-seat body 110 and the penetrating post 160 are made of TC4 titanium alloy.
