Description

Technical Field

[0001] This invention relates to the field of badminton racket technology, and more particularly to a badminton racket that is easy to store. Background Technology

[0002] Badminton can cultivate people's agility, judgment and reaction speed, and improve qualities such as speed, strength and endurance. It is popular because it can be both entertaining and good for exercise. However, traditional badminton rackets are also long when stored due to their long handles, taking up a lot of space.

[0003] For example, according to the search, Chinese Patent Publication No. CN211611530U discloses a badminton racket handle and a badminton racket. The badminton racket handle includes an adapter and a handle body. One end of the adapter is connected to the middle tube, and the other end is detachably connected to the handle body. The adapter includes an adapter body and a connecting part provided at one end of the adapter body. The connecting part is inserted and fixed to the handle body.

[0004] The aforementioned patent has the following shortcomings: the head and handle of the badminton racket are of a fixed size after being combined, and because the handle is a long and thin structure, the overall length is also relatively long when stored, taking up a lot of space and making it inconvenient to store.

[0005] Therefore, this invention proposes a badminton racket that is easy to store. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a badminton racket that is easy to store.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A badminton racket that is easy to store includes a retaining ring, strings disposed inside the retaining ring, and a handle disposed at the bottom of the retaining ring.

[0009] The handle is fixedly fitted to the fixing lugs on the bottom outer wall of the fixing ring and two semi-circular handles that form a cylindrical shape. The top of each of the two semi-circular handles is fixedly installed with a connecting rod, and the two connecting rods are rotatably connected to the inner side walls of the fixing lugs on both sides through hinge shafts.

[0010] Preferably, the tail of each of the semicircular handles is fixedly installed with an external threaded protrusion, and the outer walls of the two external threaded protrusions are connected to the same internal threaded cylinder by threads.

[0011] Furthermore: one of the semicircular handles has a slot on its inner sidewall, and the other semicircular handle has a rib fixedly installed on its outer sidewall that can engage with the slot.

[0012] Based on the aforementioned scheme: the outer side of the first rib is provided with a chamfer or rounded corner.

[0013] A preferred embodiment of the aforementioned scheme is that the hinge shaft includes a solid shaft and multiple elastic pawls fixedly installed on both sides of the solid shaft, with gaps between the elastic pawls, and the solid shaft is fixedly installed and fixed to the connecting rod, while the elastic pawls are rotatably engaged with the fixed lugs.

[0014] As a further aspect of the present invention: the outer wall of the elastic pawl is fixedly equipped with uniform ribs II, and the inner wall of the fixing ear is provided with a slot II that can engage with the ribs II.

[0015] Meanwhile, in its natural state, the second slot and the second rib are not engaged.

[0016] As a preferred embodiment of the present invention: the inner side of the elastic pawl is provided with a first inclined surface, the first inclined surface is fitted with a second inclined surface and a plug is provided, the inner wall of the plug is provided with a threaded rod, the outer end face of the threaded rod is fixed with a knob, and the inner circumferential outer wall of the threaded rod is connected to the inner wall of the solid shaft through a threaded hole opened in the inner wall of the solid shaft.

[0017] Meanwhile, the fixing ring is composed of two semi-rings with semi-circular cross sections, and the radial sidewall of the semi-rings is provided with a semi-circular hole for the clapping wire to pass through. The outer sidewall of the semi-rings is fixedly installed with a connecting lug, which is fixed by a nut and a connecting bolt.

[0018] As a preferred embodiment of the present invention: a guide groove is provided on the inner wall of one of the semi-rings at the plane, and a guide protrusion is fixedly installed on the outer wall of the other semi-ring at the plane.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention sets the handle as a combination of two semi-circular handles, and both semi-circular handles can rotate relative to the fixed ring, so that when storing, the semi-circular handles can be rotated upwards to the two sides of the fixed ring respectively, thereby reducing the length of the entire badminton racket and achieving the purpose of convenient storage.

[0021] 2. The present invention, by setting an internal threaded cylinder and an external threaded protrusion, can fix the position of the two semi-circular handles in the combined state, thereby ensuring the cylindrical structure of the entire handle and increasing the stability and comfort of the racket during use.

[0022] 3. In this invention, by setting a slot and a rib, the tendency of the two semicircular handles to slide along their respective axes can be restricted. This reduces the axial force on the threaded pair of the inner threaded cylinder and the outer threaded protrusion when they rotate in the same direction, thereby preventing thread damage and increasing service life.

[0023] 4. In this invention, by designing the hinge shaft in detail, the two ends are set as a combination structure of elastic pawls. This allows the elastic pawls to retract in conjunction with the position of the expansion plug. Combined with the engagement of the second slot and the second rib, the semi-circular handle can be kept from rotating relative to the fixed ring in the use state, thereby further increasing the structural stability during use.

[0024] 5. In this invention, by setting the fixing ring to consist of two half-rings, when a partial breakage of the string requires replacement, the nut and connecting bolt can be unscrewed to separate the two half-rings, allowing the broken string to be removed and separated at once, without having to gradually pull the string out from each semi-circular hole, thus increasing the convenience of disassembly.

Detailed Implementation

[0033] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0034] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0035] Example 1:

[0036] A type of badminton racket that is easy to store, such as Figure 1-7 As shown, it includes a fixing ring 1, a clapping line 2 disposed inside the fixing ring 1, and a handle 4 disposed at the bottom of the fixing ring 1. The handle 4 includes a fixing lug 5 fixedly sleeved on the bottom outer wall of the fixing ring 1 and two semi-circular handles 7 forming a cylinder. The top of each of the two semi-circular handles 7 is welded with a connecting rod 6, and the two connecting rods 6 are rotatably connected to the inner side walls of the fixing lug 5 on both sides through a hinge shaft 3.

[0037] When using this invention, the two semicircular handles 7 can be rotated to the bottom of the fixing ring 1, and the semicircular handles 7 can be held for use. When storing, the semicircular handles 7 can be rotated upwards to the two sides of the fixing ring 1 respectively, so that they can be stored.

[0038] This device, by setting the handle 4 as a combination of two semi-circular handles 7, and both semi-circular handles 7 can rotate relative to the fixing ring 1, allows the semi-circular handles 7 to be rotated upwards and to the two sides of the fixing ring 1 when storing, thereby reducing the length of the entire badminton racket and achieving the purpose of convenient storage.

[0039] To address stability issues; such as Figure 2 As shown, the tail of the semicircular handle 7 is welded with an external thread protrusion 9, and the outer walls of the two external thread protrusions 9 are connected to the same internal thread cylinder 8 by threads.

[0040] By setting the internal threaded cylinder 8 and the external threaded protrusion 9, the positions of the two semi-circular handles 7 in the combined state can be fixed, thereby ensuring the cylindrical structure of the entire handle 4 and increasing the stability and comfort of the racket during use.

[0041] To address the lifespan issue; such as Figure 2 As shown, one of the semicircular handles 7 has a groove 10 on its inner sidewall, and the other semicircular handle 7 has a rib 11 welded to its outer sidewall that can engage with the groove 10, and the outer side of the rib 11 is provided with a chamfer or rounded corner.

[0042] By setting the slot 10 and the rib 11, the tendency of the two semicircular handles 7 to slide along their respective axes can be restricted, thereby reducing the axial force on the threaded pair of the inner threaded cylinder 8 and the outer threaded protrusion 9 when they rotate in the same direction, thus preventing thread damage and increasing service life.

[0043] To further address stability issues; such as... Figure 3 As shown, the hinge shaft 3 includes a solid shaft 15 and a plurality of elastic pawls 12 welded to both sides of the solid shaft 15. There is a gap 14 between the elastic pawls 12, and the solid shaft 15 is welded and fixed to the connecting rod 6. The elastic pawls 12 are rotatably engaged with the fixed lug 5.

[0044] The outer wall of the elastic pawl 12 is welded with uniform ribs 17, and the inner wall of the fixing ear 5 is provided with a slot 16 that can engage with the ribs 17. When the elastic pawl 12 is in its natural state, the slot 16 and the ribs 17 are not engaged.

[0045] The inner side of the elastic pawl 12 is provided with a first inclined surface 13. The first inclined surface 13 is fitted with an expansion plug 19 through a second inclined surface 18. The inner wall of the expansion plug 19 is penetrated by a threaded rod 21. A knob 20 is fixed on the outer end face of the threaded rod 21. The outer circumference of the inner side of the threaded rod 21 is connected to the inner wall of the solid shaft 15 through a threaded hole 22 opened in the inner wall of the solid shaft 15.

[0046] When the two semicircular handles 7 are reliably engaged, the knob 20 can be turned. Through the threaded action with the threaded hole 22, the expansion plug 19 is pushed inward. This causes the elastic pawl 12 to expand outward through the engagement of the first inclined surface 13 and the second inclined surface 18, so that the second slot 16 and the second rib 17 are engaged. This locks the rotation of the elastic pawl 12 and the fixed ear 5. When it is necessary to switch the state of the semicircular handle 7, the knob 20 is turned outward. At this time, the elastic pawl 12 is contracted inward by its own elasticity, thereby separating the second slot 16 and the second rib 17. The semicircular handle 7 can rotate relative to the fixed ring 1.

[0047] This device, through detailed design of the hinge shaft 3, sets its two ends as a combination structure of elastic pawls 12, so that the elastic pawls 12 can retract in conjunction with the position of the expansion plug 19. Combined with the engagement of the second slot 16 and the second rib 17, the semi-circular handle 7 can be kept from rotating relative to the fixed ring 1 in the use state, thereby further increasing the structural stability during use.

[0048] In this embodiment, when in use, the two semicircular handles 7 can be rotated to the bottom of the fixing ring 1, and then the internal threaded cylinder 8 can be rotated to the outer wall of the external threaded protrusion 9. At the same time, the knob 20 is turned, which drives the expansion plug 19 to be squeezed inward through the threaded action with the threaded hole 22. Thus, the elastic pawl 12 is expanded outward through the cooperation of the first inclined surface 13 and the second inclined surface 18, so that the second slot 16 and the second rib 17 are engaged, thereby locking the rotation of the elastic pawl 12 and the fixing ear 5, and badminton can be played. After use, the knob 20 is turned outward. At this time, the elastic pawl 12 is contracted inward by its own toughness and elasticity, thereby separating the second slot 16 and the second rib 17. Then, the internal threaded cylinder 8 is unscrewed, and the semicircular handles 7 are rotated upward to the two sides of the fixing ring 1, so that it can be stored.

[0049] Example 2:

[0050] A type of badminton racket that is easy to store, such as Figure 6 , 7 As shown, in order to solve the problem of easy maintenance, this embodiment makes the following improvements based on embodiment 1: the fixing ring 1 is composed of two semi-rings 24 with semi-circular cross sections, and the radial sidewall of the semi-ring 24 is provided with a semi-circular hole 23 for the padding wire 2 to pass through. The outer sidewall of the semi-ring 24 is welded with a connecting ear 26, and the connecting ear 26 is fixed to the connecting bolt 27 by a nut 25.

[0051] One of the semi-rings 24 has a guide groove 28 on its inner wall at the plane, and the other semi-ring 24 has a guide protrusion 29 welded to its outer wall at the plane.

[0052] In this embodiment, when the clapping wire 2 is partially broken and needs to be replaced, the nut 25 and the connecting bolt 27 can be unscrewed, and the two half rings 24 can be separated to allow the broken clapping wire 2 to be removed and separated at once. Then, the two half rings 24 can be combined and a new clapping wire 2 can be re-inserted through the semi-circular hole 23.

[0053] This device, by setting the fixing ring 1 as two half-rings 24, allows the nut 25 and connecting bolt 27 to be unscrewed when the clapping wire 2 is partially broken and needs to be replaced. This separates the two half-rings 24, allowing the broken clapping wire 2 to be removed and separated at once, without having to gradually pull the clapping wire 2 out from each semi-circular hole 23, thus increasing the convenience of disassembly.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
