Description

Technical Field

[0001] The present invention relates to a racket handle, specifically to a racket handle and a racket assembly method. Background Art

[0002] At present, there are a large number of rackets on the market, including badminton rackets, tennis rackets, etc. Both the handle and the middle tube are provided. Generally, the racket handle is made of wood, and when installing the middle tube, an installation hole is set on the handle, and the middle tube is inserted into the installation hole and then bonded and fixed with glue. However, this method is prone to degumming, so the middle tube is very likely to fall off and fly out from the handle during use, and it may accidentally hurt people. Moreover, using wood for the handle will cause a large amount of tree felling, which is not conducive to the development of the ecological environment. Now, in order to prevent the middle tube from falling off the handle, many manufacturers will, after fixing the middle tube and the handle with glue, also fix them by passing rivets, screws or bolts through the handle and the middle tube. This method does solve the problem of easy detachment, but the structure is complex, and a riveting device is required to pass the rivets through the handle and the middle tube for fixation; as a result, the production process is complex, the production cost is high, the racket assembly efficiency is low, the racket angle cannot be adjusted, the strength is not high after long-term use, and it is not corrosion-resistant due to the erosion of sweat; in addition, the handle cannot be replaced in time after being damaged, thus affecting the use of the racket; and when the handle is damaged, the entire racket is scrapped, increasing the cost for users. Therefore, a racket handle and a racket assembly method are proposed. Summary of the Invention

[0003] The purpose of the present invention is to propose a racket handle and a racket assembly method to solve the above problems.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A racket handle and a racket assembly method, including a handle connected to the middle tube on the racket, a tapered end of the handle, and a non-slip and sweat-absorbing rubber sleeve and a rear sleeve detachably installed on the handle; the features further include a fixed head and a locking sleeve installed on the handle; the fixed head is detachably installed at the end of the handle; the locking sleeve is detachably installed and fixed inside the tapered end of the handle through the fixed head.

[0005] Further preferably, an external thread is provided on the tapered end of the handle for installing and fixing the locking sleeve, and an internal thread adapted to the external thread is provided on the fixed head. The fixed head is installed on the tapered end of the handle through the cooperation of the external thread and the internal thread.

[0006] Further preferably, a guiding surface and a limiting platform are also provided at the tapered end of the handle, and a conical surface adapted to the guiding surface is provided on the fixed head; a locking elastic piece is provided on the locking sleeve.

[0007] Further preferably, a racket fixing hole is provided on the limiting platform of the handle; the locking sleeve is clamped and installed in the tapered end of the handle through the cooperation of the guiding surface on the tapered end, the limiting platform, the fixed head and the locking elastic piece on the locking sleeve.

[0008] Further preferably, the locking sleeve is also provided with an extrusion groove for facilitating the deformation of the locking elastic piece and a through hole matching the racket fixing hole.

[0009] Further preferably, the materials of the handle, the fixed head and the locking sleeve are any one of PP, PVC and ABS.

[0010] A racket assembling method for a racket handle, characterized by comprising the following steps:

[0011] a: Install the rear sleeve on the handle, and install the locking sleeve on the limiting platform inside the tapered end of the handle;

[0012] b: First put the fixed head on the middle tube of the racket, and then pass the middle tube through the through hole of the locking sleeve and the racket fixing hole, so that the racket is preliminarily fixedly connected to the handle;

[0013] c: Move the fixed head sleeved on the middle tube of the racket to the tapered end of the handle, and then rotate the fixed head towards the tapered end of the handle. Through the connection and cooperation of the internal thread of the fixed head and the external thread on the tapered end, during the rotation process, as the fixed head rotates towards the tapered end, the contact surface between the conical surface inside the fixed head and the guiding surface on the tapered end gradually increases, so that the other end of the fixed head generates a squeezing force towards the inner locking sleeve, thereby causing the locking elastic piece of the locking sleeve to deform towards the middle tube of the racket and closely adhere to the middle tube of the racket. Until the fixed head is tightened to the end on the tapered end, the installation connection between the racket and the handle is completed; thus, the locking sleeve is locked inside the tapered end and the middle tube of the racket is locked, thereby preventing the racket from falling off;

[0014] d: Put the anti-slip and sweat-absorbing rubber sleeve on the handle to complete the assembly.

[0015] Through the design of the fixed head and the locking sleeve, the present invention facilitates the installation of the middle tube, and makes the installation between the middle tube and the handle stable and not easy to fall off; the handle material is plastic instead of wood, reducing tree felling, being beneficial to the development of the ecological environment and having high corrosion resistance and long service life.

[0024] Next, we will further explain a racket handle and a racket assembly method according to the present invention with reference to the accompanying drawings.

[0025] As Figure 1-7 shown, a racket handle and a racket assembly method in this embodiment include a handle 1 connected to the middle tube on the racket, a conical end 15 of the handle 1, and a non-slip and sweat-absorbing rubber sleeve 13 and a rear sleeve 14 detachably installed on the handle 1; it is further characterized by including a fixed head 2 and a locking sleeve 3 installed on the handle 1; the fixed head 2 is detachably installed at the end of the handle 1; the locking sleeve 3 is detachably installed and fixed in the conical end 15 of the handle 1 through the fixed head 2; the conical end 15 of the handle 1 where the locking sleeve 3 is installed and fixed is provided with an external thread 4, and the fixed head 2 is provided with an internal thread 5 adapted to the external thread 4, and the fixed head 2 is installed on the conical end 15 of the handle 1 through the cooperation of the external thread 4 and the internal thread 5; a guide surface 6 and a limit platform 9 are also provided at the conical end 15 of the handle 1, and the fixed head 2 is provided with a conical surface 7 adapted to the guide surface 6; the locking sleeve 3 is provided with a locking spring piece 10; a racket fixing hole 8 is provided on the limit platform 9 of the handle 1; the locking sleeve 3 is clamped and installed in the conical end 15 of the handle 1 through the cooperation of the guide surface 6 and the limit platform 9 on the conical end 15 and the locking spring piece 10 on the fixed head 2 and the locking sleeve 3; the locking sleeve 3 is also provided with an extrusion groove 11 facilitating the deformation of the locking spring piece 10 and a through hole 16 matching the racket fixing hole 8; the materials of the handle 1, the fixed head 2, and the locking sleeve 3 are any one of PP, PVC, and ABS.

[0026] A racket assembly method using this racket handle is characterized in that it includes the following steps:

[0027] a: Install the rear sleeve 14 onto the handle 1, and install the locking sleeve 3 onto the limiting platform 9 within the conical end 15 of the handle 1.

[0028] b: First, slip the fixing head 2 onto the middle tube of the racket, then pass the middle tube through the through hole 16 of the locking sleeve 3 and the racket rod fixing hole 8, so that the racket is preliminarily fixedly connected to the handle 1.

[0029] c: Move the fixing head 2 sleeved on the middle tube of the racket to the conical end 15 of the handle 1, then rotate the fixing head 2 towards the conical end 15 of the handle 1. Through the engagement of the internal thread 5 on the fixing head 2 and the external thread 4 on the conical end 15, during the rotation process, as the fixing head 2 rotates towards the conical end 15, the contact area between the conical surface 7 inside the fixing head 2 and the guiding surface 6 on the conical end 15 gradually increases. Thus, an extrusion force is generated at the other end of the fixing head 2 towards the internal locking sleeve 3, which prompts the locking spring piece 10 of the locking sleeve 3 to deform towards the middle tube of the racket and tightly adhere to the middle tube of the racket. Until the fixing head 2 is tightened to the end on the conical end 15, the installation connection between the racket and the handle 1 is completed; thereby locking the locking sleeve 3 within the conical end 15 and locking the middle tube of the racket, thus preventing the racket from falling off.

[0030] d: Slip the anti-slip and sweat-absorbing rubber sleeve 13 onto the handle to complete the assembly.

[0031] The beneficial effects of the present invention: Through the design of the fixing head 2 and the locking sleeve 3, it is convenient to install the middle tube, and the installation between the middle tube and the handle 1 is stable and not easy to fall off; the material of the handle 1 is plastic instead of wood, reducing tree felling and being beneficial to the development of the ecological environment; by setting the conical surface 7 and internal thread on the fixing head 2, setting the guiding surface 6 and external thread 4 on the conical end 15 of the handle 1, and setting the locking spring piece 10 on the locking sleeve 3, the guiding surface 6 is for facilitating installation and plays a guiding role during installation; through the settings of the thread, the locking spring piece 10 and the conical surface 7, during the continuous tightening process during installation, an extrusion force is formed on the locking spring piece 10. By setting the extrusion groove 11 on the locking sleeve 3, it prompts the locking spring piece 10 to expand towards the extrusion groove 11 while being extruded downward due to the extrusion force, so that the contact between the locking spring piece 10 and the middle tube is closer, greatly increasing the contact area between the locking sleeve 3 and the middle tube, increasing the frictional resistance, making the connection between the middle tube and the handle 1 more stable and not easy to fall off, and being safer during use; the assembly is simple, detachable and replaceable. When the handle is damaged, it can be replaced, saving the user's cost, and the racket angle can be adjusted arbitrarily during installation; by using any one of PP, PVC, and ABS as the materials of the handle 1, the fixing head 2, and the locking sleeve 3, it has good corrosion resistance and a long service life.

[0032] The protection scope of the present invention is not limited to the above embodiments and their variations. Any conventional modifications and substitutions made by those skilled in the art based on the content of this embodiment fall within the protection scope of the present invention.
