Description

Technical Field

[0001] The present invention relates to the technical field of storage cabinets, and particularly to a tennis racket storage cabinet and its usage method. Background Art

[0002] In the context of the popularization of tennis, the storage and protection of rackets have become important requirements for sports enthusiasts and venue management. The traditional storage method for tennis rackets is generally to place the racket in a racket backpack and then place the racket backpack in a storage locker. This kind of storage not only greatly wastes storage space but also may not be able to store the racket due to insufficient space in the storage locker. In addition, simple brackets, hanging devices, or hard storage boxes are also used for storage. However, due to uneven fixing methods, this kind of storage is likely to cause the racket frame to deform or the paint surface to wear. Especially for high-end rackets made of carbon fiber, improper storage for a long time may affect their mechanical properties. At the same time, when multiple rackets are stored together, there is a lack of effective buffer isolation measures, and the rackets are prone to collision, which may lead to the racket rod breaking, the stringing being damaged, or the racket face being dented. This problem is particularly prominent in public storage scenarios where rackets are frequently taken and used (such as stadiums, gyms). Summary of the Invention

[0003] In view of the above technical problems, the present invention proposes the following technical solutions:

[0004] A tennis racket storage cabinet includes a sundries box, a racket box, a protective cover, a main body bracket, and tennis rackets. The protective cover is fixedly installed on the top of the main body bracket to protect the device. One sundries box and one racket box form a storage unit, and multiple storage units are arranged in the main body bracket. The sundries box is used to store sundries such as clothes, schoolbags, personal items, etc., and the racket box is used to store multiple tennis rackets. Its characteristics are as follows: The racket box includes a fixed frame and a rotating frame. The tennis rackets are stored in the storage space formed by the closure of the fixed frame and the rotating frame. The storage space formed by the fixed frame and the rotating frame is similar to the shape of the tennis racket. An isolation space is arranged in the rotating frame, and two clamping frames are slidably installed on the rotating frame. One end of the clamping frame is arranged in the storage space, and an airbag is fixedly installed on the clamping frame. The airbag is used to limit the position of the tennis racket in the storage space. The material of the airbag is rubber. When in use, the airbag is inflated through external gas input, and the tennis racket is fixed by the inflation of the airbag squeezing the tennis racket.

[0005] Furthermore, an air pump is fixedly installed in the rotating frame. The air pump is arranged in the isolation space. The air inlet end of the air pump is arranged outside the rotating frame to facilitate the replacement of the gas in the air pump. A plurality of air pipes are fixedly installed on the airbag, and one end of the air pipe away from the airbag is connected to the air outlet end of the air pump. The air pump is used to provide the expanding gas for the airbag to make the airbag expand.

[0006] Further, a motor is fixedly installed in the isolation space of the rotating frame, a rotating shaft is fixedly installed on the output shaft of the motor, and a plurality of adjusting lead screws with different pitches are arranged on the rotating shaft.

[0007] Further, the pitches of the plurality of adjusting lead screws on the rotating shaft increase step by step in a ladder shape. The pitch of the adjusting lead screw closest to the motor among the plurality of adjusting lead screws on the rotating shaft is the smallest, and the pitch of the adjusting lead screw farthest from the motor is the largest. The adjusting lead screw on the rotating shaft is threadedly connected to one end of the clamping frame arranged in the isolation space.

[0008] Further, a plurality of fixed linings are arranged on the inner wall of the fixed frame. The fixed linings are made of foam material. A rotating lining is arranged in the rotating frame, and the material of the rotating lining is foam material.

[0009] Further, a pulling handle is arranged on the outer wall of the rotating frame for convenient use, and the rotating frame is rotatably connected to the fixed frame.

[0010] Further, a card seat is fixedly installed on the rotating frame. The card seat is made of rubber material. The plurality of card seats are used to clamp the handle part of the tennis racket. When the tennis racket is embedded between the card seats, the card seat can fix the tennis racket through elastic deformation.

[0011] A using method of a tennis racket storage cabinet includes the following steps:

[0012] S1. Pull the rotating frame and make the rotating frame rotate 60 degrees to 80 degrees on the fixed frame;

[0013] S2. Hold the handle part of the tennis racket with one hand and embed the handle part of the tennis racket between the card seats;

[0014] S3. Start the motor to make the rotating shaft rotate and adjust the placement space of the head part of the tennis racket;

[0015] S4. Hold the head part of the tennis racket with one hand and place the head of the tennis racket between the clamping frames corresponding to the card seats;

[0016] S5. Visually check that the placement position of the tennis racket on the rotating frame has no obvious deviation or inclination, and then release the support for the tennis racket;

[0017] S6. Start the air pump to drive the air flow. The air in the air pump enters the airbag through the air pipe, and the airbag expands through the gas and then squeezes and fixes the tennis racket;

[0018] S7. Pull the rotating frame to close the storage space. After that, the side of the tennis racket away from the rotating frame contacts the fixed lining, and the fixed lining will also clamp the tennis racket after being squeezed.

[0019] The beneficial effects of the present invention compared with the prior art are as follows: (1) The device clamps the tennis racket through the inflation of the airbag, so that the tennis racket will be evenly fixed in the storage space, and there will be no collision between each tennis racket. Clamping the tennis racket in this way can not only improve the safety of the tennis racket when placed, but also avoid mutual abrasion between the tennis rackets; (2) The device clamps the tennis racket through multiple flexible components, reducing the damage of the tennis racket during storage, and at the same time improving the stability of the tennis racket during storage.

DETAILED DESCRIPTION OF THE INVENTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] AsFigure 1 As shown in Figure 2 , a tennis racket storage cabinet includes a sundries box 10, a racket box 20, a protective cover 30, and a main body bracket 40. The protective cover 30 is fixedly installed on the top of the main body bracket 40 to protect the device. One sundries box 10 and one racket box 20 form a storage unit. Multiple storage units are provided in the main body bracket 40. The sundries box 10 is used to store the user's sundries, such as clothes, schoolbags, personal items, etc. The racket box 20 stores multiple tennis rackets 50. When in use, the racket box 20 only stores tennis rackets 50, and the tennis rackets 50 stored in the racket box 20 are evenly distributed, and each tennis racket 50 does not touch each other. The sundries box 10 and the racket box 20 are generally fixedly connected. In other usage methods, the storage unit can be composed of only the racket box 20, and such a storage unit can only store tennis rackets 50.

[0032] As shown in Figure 1 As shown in Figure 2 , the sundries box 10 is composed of a storage box and a switch door. The storage box is rotatably connected to the switch door, and an electronic lock can be set at the positions of the storage box and the switch door for anti-theft. In addition, such an electronic lock can be replaced by other existing anti-theft devices.

[0033] As shown in Figures 2 to 9 , the racket box 20 includes a fixed frame 201 and a rotating frame 203. The tennis racket 50 is stored in the storage space formed by the closure of the fixed frame 201 and the rotating frame 203. The storage space formed by the fixed frame 201 and the rotating frame 203 is similar to the shape of the tennis racket 50. A plurality of fixed linings 202 are provided on the inner wall of the fixed frame 201. The fixed linings 202 are made of foam material. The fixed linings 202 mainly prevent the tennis racket 50 from directly contacting the inner wall of the fixed frame 201. At the same time, the fixed linings 202 can also play a limiting role on the tennis racket 50 after being squeezed and deformed. A pulling handle is provided on the outer wall of the rotating frame 203 for easy use. The rotating frame 203 is rotatably connected to the fixed frame 201. An electronic lock is provided on the rotating frame 203 for anti-theft. In addition, the electronic lock on the rotating frame 203 can be replaced by a common buckle lock and an external lock for anti-theft.

[0034] As shown in Figures 2 to 9As shown, an isolation space is provided inside the rotating frame 203. Two clamping frames 204 are slidably mounted on the rotating frame 203. One end of the clamping frame 204 is disposed in the storage space. An airbag 205 is fixedly mounted on the clamping frame 204. The airbag 205 is used to limit the position of the tennis racket 50 in the storage space. The material of the airbag 205 is rubber. When in use, the airbag 205 expands through external gas input. By the expansion of the airbag 205 to squeeze the tennis racket 50, the fixing effect is achieved. A sundry box 10 is fixedly mounted on the inner wall of the storage space where the rotating frame 203 is located. The sundry box 10 is used to cooperate with the outermost airbag 205 to clamp the airbag 205. A rotating inner lining 212 is provided inside the rotating frame 203. The material of the rotating inner lining 212 is foam. The rotating inner lining 212 mainly prevents the tennis racket 50 from directly contacting the inner wall of the rotating frame 203.

[0035] As Figures 2 to 7 shown, an air pump 207 is also fixedly mounted inside the isolation space of the rotating frame 203. The air pump 207 is disposed in the isolation space. The air inlet end of the air pump 207 is disposed outside the rotating frame 203 to facilitate the replacement of the gas inside the air pump 207. A plurality of air pipes 206 are fixedly mounted on the airbag 205. One end of the air pipe 206 away from the airbag 205 is connected to the air outlet end of the air pump 207. The air pump 207 is used to provide the expanding gas for the airbag 205 to make the airbag 205 expand.

[0036] As Figures 2 to 7 shown, a motor 208 is fixedly mounted inside the isolation space of the rotating frame 203. A rotating shaft 209 is fixedly mounted on the output shaft of the motor 208. A plurality of adjusting lead screws with different pitches are provided on the rotating shaft 209. The pitches of the plurality of adjusting lead screws on the rotating shaft 209 increase step by step. Among the plurality of adjusting lead screws on the rotating shaft 209, the adjusting lead screw closest to the motor 208 has the smallest pitch, and the adjusting lead screw farthest from the motor 208 has the largest pitch. The adjusting lead screws on the rotating shaft 209 are threadedly connected to the end of the clamping frame 204 disposed in the isolation space. The adjusting lead screws that increase step by step are used to adjust the placement width of the tennis racket 50 on the clamping frame 204. When the rotating shaft 209 rotates, the clamping frame 204 will move away from the sundry box 10. Because the pitches of the adjusting lead screws engaged by each clamping frame 204 are different, the moving distance of the clamping frame 204 increases from the direction close to the motor 208 to the direction away from the motor 208 under the same rotation speed of the rotating shaft 209. Therefore, the situation in the storage space is that the placement width of each tennis racket 50 increases, which is for placing tennis rackets of different widths.

[0037] As Figures 2 to 7As shown, a card holder 211 is fixedly installed on the rotating frame 203. The card holder 211 is made of rubber material. The handle part of the tennis racket 50 is clamped between the multiple card holders 211. When the tennis racket 50 is inserted between the card holders 211, the card holder 211 can fix the tennis racket 50 through elastic deformation.

[0038] A method for using a tennis racket storage cabinet includes the following steps:

[0039] S1. Pull the rotating frame 203 and make the rotating frame 203 rotate 60 to 80 degrees on the fixed frame 201;

[0040] S2. Hold the handle part of the tennis racket 50 with one hand and insert the handle part of the tennis racket 50 between the card holders 211;

[0041] S3. Start the motor 208 to make the rotating shaft 209 rotate and adjust the placement space of the head part of the tennis racket 50;

[0042] S4. Support the head part of the tennis racket 50 with one hand and place the head of the tennis racket 50 between the clamping frames 204 corresponding to the card holders 211;

[0043] S5. If there is no obvious deviation or inclination in the placement position of the tennis racket 50 on the rotating frame 203, release the support for the tennis racket 50;

[0044] S6. Start the air pump 207 to drive the air flow. The air in the air pump 207 enters the airbag 205 through the air pipe 206, and the airbag 205 expands through the gas and then squeezes and fixes the tennis racket 50;

[0045] S7. Pull the rotating frame 203 to close the storage space. Then, the side of the tennis racket 50 away from the rotating frame 203 contacts the fixed inner lining 202, and the fixed inner lining 202 will also clamp the tennis racket 50 after being squeezed.

[0046] Working principle: When this device is in use, the sundry box 10 can store clothes or other sundries. When the tennis racket box 20 stores the tennis racket 50, the user pulls the rotating frame 203 to make the rotating frame 203 rotate 60 to 80 degrees on the fixed frame 201. Then, the user holds the handle part of the tennis racket 50 with one hand and supports the head part of the tennis racket 50 with the other hand. First, the handle part of the tennis racket 50 is inserted between the clamping seats 211. At this time, it can be visually checked whether the head part of the tennis racket 50 can be placed between the clamping frames 204. If the space between the clamping frames 204 is not enough, then the motor 208 is started to make the rotating shaft 209 rotate. Further, the clamping frames 204 are made to rotate, so as to adjust the placement space of the head part of the tennis racket 50. After the adjustment is completed, the head of the tennis racket 50 is placed between the clamping frames 204 corresponding to the clamping seats 211. At this time, it should be noted that both ends of the tennis racket box 20 must be placed between the clamping frames 204 corresponding to the clamping seats 211, and the tennis racket 50 cannot be deflected during placement to prevent the racket rod or the head of the tennis racket 50 from being bent when the tennis racket 50 is clamped. Finally, the air pump 207 is started to drive the air flow, so that the air in the air pump 207 enters the airbag 205 through the air pipe 206. The airbag 205 expands through the gas and then squeezes and fixes the tennis racket 50. Then the storage space is closed. After the storage space is closed, the side of the tennis racket 50 away from the rotating frame 203 contacts the fixed inner lining 202. After being squeezed, the fixed inner lining 202 will also clamp the tennis racket 50. In this way, the tennis racket 50 will be evenly fixed in the storage space, and there will be no collision between each tennis racket 50. At the same time, the tennis racket 50 is clamped by multiple flexible components, and the structural components of the tennis racket 50 will not be damaged.

[0047] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
