Description

Technical Field

[0001] The utility model mainly relates to the technical field of badminton, in particular to an assembly structure of a ball skirt and a ball head. Background Art

[0002] Badminton mainly consists of two important structures: feathers and head. In the current assembly of artificial badminton, a drill is usually used to drill holes on the top of the head, and glue is used to complete the bonding assembly of the head and feathers. The badminton head bonded with glue will have uneven mass distribution. At the same time, glue bonding will cause poor concentricity between the feathers and the head, resulting in a decrease in the yield rate of badminton assembly production.

[0003] The inventor proposed an assembly structure of a ball skirt and a ball head based on the process flow of self-developed badminton equipment. Through the interference fit between the ball head and the ball skirt, there is no need to use glue for the assembly of the badminton, which makes it convenient for the factory to control the weight of the product during the production process of badminton. By controlling the assembly links such as the open ring groove in the badminton assembly equipment, the concentricity of the ball skirt and ball head of the finished badminton product is improved.

[0014] An anti-slip surface is fixedly arranged on the outer side of the bottom of the contact ring, and the anti-slip surface extends to the bottom of the inner wall of the ring groove.

[0015] Furthermore, the depth of the annular groove is the same as the height of the contact ring.

[0016] Furthermore, a core column is fixedly provided in the middle of the ball head, and the outer side of the core column is nested with the inner wall of the contact ring.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0019] The utility model provides an assembly structure of a ball skirt and a ball head. During the assembly process of the ball skirt and the ball head, in order to ensure the assembly yield rate of badminton products, the centers of the ball skirt and the ball head need to be on the same axial direction.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] Refer to the attached Figure 1-4 The utility model provides an assembly structure of a ball skirt and a ball head, including the following structure:

[0036] The ball skirt 1 has a contact piece 2 fixedly disposed at the bottom thereof, and a contact ring 3 fixedly disposed at the bottom thereof.

[0037] The ball head 4 has an annular groove 5 fixedly disposed in the middle of the top surface of the ball head 4 .

[0038] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the center of the ball skirt 1 and the center of the ball head 4 are maintained in the same axial direction.

[0039] During the assembly of the skirt 1 and the head 4, in order to ensure the assembly yield of the badminton product, the centers of the skirt 1 and the head 4 need to be on the same axial line.

[0040] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the bottom surface of the contact piece 2 abuts against the top surface of the ball head 4, and the center of the contact piece 2 and the center of the ball head 4 are maintained in the same axial direction.

[0041] A mounting hole 21 is fixedly provided in the middle of the contact piece 2 .

[0042] The assembly hole 21 on the contact piece 2 cooperates with the assembly head in the badminton assembly equipment, so that the badminton assembly equipment can easily complete the assembly of the ball skirt 1 on the ball head 4.

[0043] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the contact ring 3 extends into the annular groove 5 of the ball head 4, the center of the contact ring 3 and the center of the annular groove 5 are maintained in the same axial direction, and the bottom of the contact ring 3 is interference fit with the middle of the ball head 4.

[0044] An anti-slip surface 31 is fixedly provided on the outer side of the bottom of the contact ring 3 , and the anti-slip surface 31 extends to the bottom of the inner wall of the annular groove 5 .

[0045] The structural design of the contact ring 3 and the anti-slip surface 31 allows the assembly head in the badminton assembly equipment to be quickly pressed into the annular groove 5 of the ball head 4, thereby preventing the contact ring 3 from falling off from the annular groove 5.

[0046] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the depth of the annular groove 5 is the same as the height of the contact ring 3 .

[0047] The depth of the annular groove 5 needs to match the height of the contact ring 3 to ensure that the contact ring 3 is completely embedded in the annular groove 5 .

[0048] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a core column is fixedly arranged in the middle of the ball head 4 , and the outer side of the core column is embedded in the inner wall of the contact ring 3 .

[0049] The retention of the core column avoids waste generated by grooving the ball head 4 in the badminton assembly equipment. The structural coordination between the core column and the ball head 4 improves the assembly stability of the contact ring 3 in the ring groove 5, ensuring that the ball skirt 1 is stably assembled on the ball head 4.

[0050] Specific operation process:

[0051] During the assembly process of the ball skirt 1 and the ball head 4, in order to ensure the assembly yield rate of the badminton product, the centers of the ball skirt 1 and the ball head 4 need to be on the same axial direction, and the structural design of the contact ring 3 and the anti-slip surface 31 allows the assembly head in the badminton assembly equipment to be quickly pressed into the annular groove 5 of the ball head 4 to prevent the contact ring 3 from falling off the annular groove 5. The structural coordination of the core column and the ball head 4 improves the assembly stability of the contact ring 3 in the annular groove 5, ensuring that the ball skirt 1 is stably assembled on the ball head 4.

[0052] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
