DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0027] Please refer to Figures 1-6 The utility model provides a pattern can change's racket cap rear cover structure, including rear cover part 3, bottom support plate 4, through -hole 5, cover buckle plate 7, pattern paper surface 9, the rim portion of bottom support plate 4 and cover buckle plate 7 is wrapped around the side ring surface of rear cover part 3, pattern paper surface 9 is placed between bottom support plate 4 and cover buckle plate 7, the upper end surface left side of cover buckle plate 7 is fixed with through -hole 5 and is convenient for fluid pigment to import rear cover part 3, bottom support plate 4 and cover buckle plate 7 are wrapped with rear cover part 3 between through the interlayer, the interlayer is pattern paper surface 9 and the space that fluid pigment can replace filling, through -hole 5 conduction bottom support plate 4 and the interlayer between cover buckle plate 7 can be evacuated.
[0028] Because the cap of racket often needs the athlete to print the pattern of laser engraving or drawing coloring spray paint and so on and print the figure and character to show that it belongs to the racket of his own special, but the change of racket style and the same racket athlete use long cycle after the pattern want to change but more difficult, the loss of thread groove and pigment color block attachment after laser printing or coloring scribble cap loss, it is inconvenient to clean, and the original cap surface pit and wear are more serious, and the coloring of secondary laser engraving is not flat, also consumes the service life of racket handle cap, the frequency of changing cap and cost is higher.
[0029] It should be noted that the interlayer between bottom support plate 4 and cover buckle plate 7 can be vacuumed to form a vacuum interlayer, which can also be an ordinary interlayer. The pattern paper surface 9 and the fluid pigment can be replaced in the vacuum interlayer and the ordinary interlayer, realizing the convenient and non-destructive replacement operation of the cap rear cover.
[0030] The rear cover part 3 is provided with a triangular buckle groove 31 and a ring frame 32, the triangular buckle groove 31 is provided with two left and right sides respectively fixed inside the ring frame 32, and the ring frame 32 is buckled together with the cover buckle plate 7 through the triangular buckle groove 31.
[0031] It should be noted that the triangular buckle groove 31 and the triangular protrusion 71 are buckled, so that the ring frame 32 wraps the cover plate 72 to realize the upper sealing operation.
[0032] The cover buckle plate 7 is provided with a triangular lug 71, a cover plate 72, and a through hole inner groove 73. The through hole inner groove 73 is arranged inside the left side of the cover plate 72 and is an integral structure. The triangular lug 71 is provided with two triangular lugs and is respectively arranged on the left and right sides of the cover plate 72. The cover plate 72 is buckled together with the rear cover part 3 through the triangular lug 71.
[0033] It should be noted that the triangular buckle groove 31 is buckled with the triangular lug 71, so that the ring mouth frame 32 wraps the cover plate 72 to realize the upper sealing operation.
[0034] The inner wall 6 is arranged on the top of the rear cover part 3. The left and right sides of the inner wall 6 are respectively tightly attached to the side wrapping plate 8. The front and rear sides of the inner wall 6 are respectively tightly attached to the mesh plate 2. The top of the inner wall 6 is nested with the closing frame 1. The closing frame 1, the mesh plate 2, the side wrapping plate 8, and the inner wall 6 are stamping formed as an integral structure.
[0035] It should be noted that the closing frame 1, the mesh plate 2, the side wrapping plate 8, and the inner wall 6 are combined to form the racket handle cap structure of the rear cover part 3, which is convenient for wrapping the tail end of the handle, improves the handle and cap anti-oral occlusion force, and the mesh plate 2 increases the friction grip, so that the combined sandwich layer of the rear cover part 3 also has a gap space for protecting the tail end of the handle.
[0036] The through hole 5 conducts the sandwich layer wrapped by the rear cover part 3 between the bottom supporting plate 4 and the cover buckle plate 7 to be vacuumized. There is a vacuum sandwich layer between the bottom supporting plate 4 and the cover buckle plate 7. The vacuum sandwich layer is a space that can be filled with pattern paper 9. The vacuum sandwich layer is also a space that can be filled with fluid paint.
[0037] It should be noted that the fluid paint in the vacuum sandwich layer can wrap the pattern paper 9 to fix the color and prevent fading and vacuum oxidation, improve the complete retention degree of the pattern in the handle cap rear cover, and still be durable and complete when replaced.
[0038] The through hole 5 and the through hole inner groove 73 are stamping formed as an integral structure and are mutually penetrated.
[0039] It should be noted that the through hole 5 and the through hole inner groove 73 can vacuumize the sandwich layer space, and fluid paint or transparent color fluid liquid can be introduced, which can fix the color of the pattern paper 9 and prevent fading and liquid sealing oxidation.
[0040] The design of the racket cap rear cover is wrapped with the bottom plate 4 and the cover plate 7 through the rear cover part 3 to form a double-plate slot structure with a vacuum interlayer. The staff connects the vacuum interlayer in the inner wall 6 through the through hole 5. When the athlete needs to change the pattern, the fluid bottom color is filled into the through hole slot 73, and then the through hole 5 extracts the interlayer air to form a vacuum effect. The pattern changing operation effect is formed by the pattern paper surface 9 under the cover plate 72. The color of the racket cap rear cover itself can be changed by the single pigment fluid bottom color, and the pattern can also be changed by the single paper operation. Both of them can also be combined to operate. The triangular buckle slot 31 of the ring port frame 32 buckles the triangular protruding block 71 to ensure that the cover plate 72 presses the pattern paper surface 9 on the bottom plate 4 and the interlayer is stable. Through the double-plate interlayer cap prefabrication processing, the racket rear cover structure avoids laser printing and engraving loss, and avoids excessive pigment color coverage. It realizes a kind of racket cap rear cover pattern changing operation effect that keeps new and undamaged, prolongs the service life of the cap rear cover and avoids replacement and consumption cost.
[0041] Through the staff assembling the bottom plate 4 and the cover plate 7 on the upper and lower sides of the rear cover part 3, the racket cap rear cover single plate is formed in the conventional technology to increase the double-plate and interlayer structure design effect. The interlayer built-in liquid improves the damping and buffering effect of the racket handle cap on the impact of the racket, and the pattern paper sample can be conveniently changed. It ensures that the sports personnel can change without damage, and high-frequency replacement does not need to worry about the cap rear cover loss. The buckle is convenient to disassemble, and the assembly is convenient.
[0042] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application.
