Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

The purpose of this utility model is to provide an integral artificial badminton to solve the problems existing in the prior art.

In order to make the above-mentioned purposes, features and advantages of the present utility model more obvious and easy to understand, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

The integral artificial badminton in this embodiment, as shown in Figures 1-4, includes a ball head 1, a feather seat 2 and a feather 3; the top end of the ball head 1 is provided with a groove 11 downward, and the bottom of the groove 11 is An annular slot 12 is provided downward. The feather seat 2 includes a cylinder 21 for inserting into the slot 12 and a supporting circular plate 22 provided on the top of the cylinder 21 for inserting into the groove 11. The supporting circular plate 22 A number of feathers 3 are arranged on the outer periphery of the feather 3. The feathers 3 include an integrally formed feather piece 31 and a feather stem 32. The feather piece 31 is arranged on the top of the feather stem 32, and the bottom of the feather stem 32 is connected to the support circular plate 22; the cylinder 21, the support The circular plate 22 and the feather 3 are an integrally formed structure.

In order to ensure that the feather seat 2 is firmly fixed after being inserted into the ball head 1, a ring of annular clamping parts 24 is provided at the bottom of the cylinder 21. The annular clamping part 24 is squeezed into the slot 12 through the top opening of the slot 12, and is finally forced to squeeze. into the bottom side wall of the slot 12 to realize the axial limitation of the feather seat 2.

The cylinder wall of the cylinder 21 is also provided with two limiting portions 23 protruding outward. The two limiting portions 23 are arranged symmetrically. The width of the limiting portions 23 gradually narrows from the top to the bottom. The limiting portions 23 are in a circular shape. When the barrel 21 is inserted into the slot 12, the stopper 23 is forced to squeeze into the side wall of the slot 12 by force, thereby preventing the feather seat 2 and the ball head 1 from coming together in the axial and radial directions. .

In this specific embodiment, the groove 11 is a tapered groove with a diameter gradually decreasing from the top to the bottom, and the supporting circular plate 22 is a conical plate matching the groove 11 .

In this specific embodiment, there are 16 feathers 3 in total, which are feathers 3 in the shape of imitating natural goose feathers or duck feathers; at the same time, in order to achieve the best hitting effect with the strength, toughness and elasticity of the feather stems 32, the outer dimensions of the feather stems 32 are similar to those of natural feathers. Goose feather duck feather stem 32, the structural shape adopts an asymptotic U shape. The feather piece 31 and the imitation feather 3 adopt a forming mold, and a heating element is installed on the mold to generate high temperature. The temperature reaches the melting point of the plastic. The melting and pressing molding process turns the feather piece into imitation wool.

In this specific embodiment, the feather seat 2 and the feathers 3 are made of plastic material.

The manufacturing method of the integral artificial badminton in this embodiment is as follows:

After the feather base 2 and the feathers 3 are integrally molded by precision injection molding, each feather 3 after molding is in a horizontally expanded state (as shown in Figure 5). The root of the feather stem 32 has a connection point with the supporting circular plate 22 of the feather base 2. The upper end of the root of the feather stem 32 is vertically provided with clamping blocks 33, and the top of the supporting circular plate 22 is circumferentially distributed with clamping grooves 34 corresponding to each clamping block 33 (as shown in Figure 6). The heated feather stem 32 and The connection points of the supporting circular plate 22 enable each feather 3 to stand up, and then each clamping block 33 is fitted into the corresponding slot 34, and then the feather stem 32 and the supporting circular plate 22 are fused into one body; and then the The feather seat 2 with the feathers 3 is inserted into the slot 12 and the groove 11 of the ball head 1 to complete the assembly of the badminton.

Specifically, the feather stem 32 and the supporting circular plate 22 are fused into one body through an ultrasonic welding process.

In order to enable the blocking block 33 to be limited in the radial direction after being inserted into the blocking slot 34, a semicircular limiting portion 35 is protrudingly provided on the side of the blocking block 33 away from the end of the feather stem 32. The limiting portion 35 can The clamping block 33 is limited in the semicircular limiting groove 36 provided on one side of the clamping slot 34 so that the clamping block 33 can achieve radial limitation.

This utility model uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method of the utility model and its core idea; at the same time, for those of ordinary skill in the field, According to the idea of the present utility model, there will be changes in the specific implementation mode and application scope. In summary, the contents of this specification should not be construed as limitations of the present invention.
