Description

Technical Field

[0001] This utility model relates to the field of water cup holder technology, and in particular to a retractable water cup holder. Background Technology

[0002] Water cups are common containers for holding liquids in daily life. They are usually cylindrical for easy handling. Water cups are made of various materials, including glass, ceramic, plastic and metal, and are suitable for holding liquids such as water and beverages. In addition, water cups also symbolize nourishment and the source of life, reminding people to maintain good health. Water cups are usually placed and secured using a cup holder.

[0003] However, in the existing technology, the existing cup holders are usually designed with a fixed size. The fixed design means that the cup holder can only fit one size cup. If the cup is too large, it cannot be put into the cup holder. If the cup is too small, the cup holder cannot effectively fix the cup after it is put into the cup holder, and it is easy to wobble. This is inconvenient for people to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a retractable cup holder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a retractable cup holder, comprising: a main frame, three fixed clamps on the top of the main frame, a telescopic structure on the inner side of the main frame, a fixed structure on the bottom of the main frame, the telescopic structure including three sliding plates, a horizontal plate fixedly installed on the bottom of each of the three sliding plates, a movable column rotatably installed on the bottom of each of the three horizontal plates, a connecting column rotatably installed on the top of the inner side of the main frame, a rotating disk fixedly installed on the bottom of the connecting column, a gear fixedly installed on the bottom of the rotating disk, a rack meshing with the outer side of the gear, a connecting plate fixedly installed on one side of the rack, and a pull ring fixedly installed on one side of the connecting plate.

[0006] In a preferred embodiment, a limiting plate is fixedly installed on the inner side of the main frame, and fixed seats are fixedly installed on both the front and rear sides of the rack. A return spring is fixedly installed between the limiting plate and the two fixed seats, and the rack passes through the limiting plate and slides in contact with the limiting plate.

[0007] In a preferred embodiment, the top of the main frame is provided with three elongated sliding grooves, and the three sliding plates are respectively disposed inside the three elongated sliding grooves and slide in contact with the main frame.

[0008] In a preferred embodiment, the rotating disk has three arc-shaped grooves, and the three movable columns are respectively disposed inside the three arc-shaped grooves and slide in contact with the rotating disk.

[0009] In a preferred embodiment, the fixing structure includes a circular base plate, a fixing suction cup fixedly installed at the bottom of the circular base plate, and two elastic sheets fixedly installed at the top of the circular base plate, with a limit block fixedly installed on one side of each of the two elastic sheets.

[0010] In a preferred embodiment, limit slots are provided on both sides of the main frame, and the two limit blocks are adapted to the two limit slots respectively.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model utilizes the elastic effect of two return springs to drive the rack to move, causing the rack to drive the gear to mesh and rotate, thereby causing the rotating disk to rotate, which in turn drives the three moving columns to move, thereby causing the three fixed clamping plates to retract towards the center position to fix the cup placed on the top of the main frame. This allows the device to fix cups of different sizes, effectively improving the applicability of the cup holder. 2. The elasticity of the elastic sheet will press the limiting block against the inside of the main frame. When the main frame comes into contact with the circular base plate, the limiting block will pop out from the limiting slot through the elasticity of the elastic sheet, thereby fixing the main frame and the circular base plate. This completes the replacement of the fixing suction cup. The operation is simple and effectively improves the convenience of using the cup holder. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figure 1-3 As shown, this utility model provides a technical solution: a retractable cup holder, comprising: a main frame 11, three fixed clamps 12 on the top of the main frame 11, a telescopic structure 2 on the inner side of the main frame 11, a fixed structure 3 on the bottom of the main frame 11, the telescopic structure 2 including three sliding plates 21, a horizontal plate 22 fixedly installed on the bottom of each of the three sliding plates 21, a movable column 23 rotatably installed on the bottom of each of the three horizontal plates 22, a connecting column 24 rotatably installed on the top of the inner side of the main frame 11, a rotating disk 25 fixedly installed on the bottom of the connecting column 24, a gear 26 fixedly installed on the bottom of the rotating disk 25, a rack 27 meshing with the outer side of the gear 26, and the rack 27... A connecting plate 28 is fixedly installed on one side, and a pull ring 29 is fixedly installed on one side of the connecting plate 28. A limit plate 210 is fixedly installed on the inner side of the main frame 11. Fixed seats 211 are fixedly installed on both the front and rear sides of the rack 27. A return spring 212 is fixedly installed between the limit plate 210 and the two fixed seats 211. The rack 27 passes through the limit plate 210 and slides in contact with the limit plate 210. Three long strip-shaped slide grooves are opened on the top of the main frame 11. Three sliding plates 21 are respectively set in the three long strip-shaped slide grooves and slide in contact with the main frame 11. Three arc-shaped slide grooves are opened on the rotating disk 25. Three moving columns 23 are respectively set in the three arc-shaped slide grooves and slide in contact with the rotating disk 25.

[0019] In this embodiment, the three elongated grooves on the main frame 11, in conjunction with the three sliding plates 21, effectively limit the movement of the fixed clamping plates 12, ensuring that the three fixed clamping plates 12 can only extend outward or retract inward, thus preventing the three fixed clamping plates 12 from shifting. The three arc-shaped grooves on the rotating disk 25, in conjunction with the three moving columns 23, allow the three moving columns 23 to slide within the three arc-shaped grooves when the rotating disk 25 rotates. Because the sliding plates 21 above the moving columns 23 are limited by the elongated grooves, the three moving columns 23 will not rotate with the rotating disk 25, but will move horizontally to drive the three fixed clamping plates 12 at the top to extend outward or retract inward accordingly. The rack 27, which passes through the limiting plate 210, effectively limits the movement of the rack 27, ensuring that the rack 27 will not be misaligned and guaranteeing the meshing effect between the gear 26 and the rack 27.

[0020] Example 2 like Figure 1 and 4 As shown, the fixed structure 3 includes a circular base plate 31, a fixed suction cup 32 is fixedly installed at the bottom of the circular base plate 31, two elastic pieces 33 are fixedly installed at the top of the circular base plate 31, and a limit block 34 is fixedly installed on one side of each of the two elastic pieces 33. Limit slots 35 are opened on both sides of the main frame 11, and the two limit blocks 34 are adapted to match the two limit slots 35 respectively.

[0021] In this embodiment, the fixed suction cup 32 allows the cup holder to be easily placed in any position. The suction force of the fixed suction cup 32 secures the cup holder, ensuring stability when placed. The elastic pieces 33 are elastic and can bend and retract when the main frame 11 is pressed down on the circular base plate 31. This positions the two elastic pieces 33 and the limiting blocks 34 inside the main frame 11. After the main frame 11 and the circular base plate 31 are in contact, the two limiting blocks 34 are in the two limiting slots 35. The position of the limiting block 34 can be popped out from the limiting slot 35 by the elastic action of the elastic sheet 33, thereby limiting the position between the main frame 11 and the circular base plate 31 and thus completing the fixation. The limiting block 34 is designed with a bevel on one side, so that when the main frame 11 is pressed down on the top of the circular base plate 31, the limiting block 34 will not block the bottom edge of the main frame 11. The edge of the main frame 11 will be pressed down along the bevel of the limiting block 34, and the limiting block 34 will also bend accordingly by the elastic action of the elastic sheet 33 to adapt to the downward pressure of the main frame 11.

[0022] Working principle: like Figure 1-4As shown, in use, the main frame 11 is placed and fixed by the suction cup 32. Then, pulling the pull ring 29 moves the rack 27 through the connecting plate 28, which in turn drives the gear 26 to mesh and rotate, causing the rotating disk 25 to rotate as well. This causes the three moving columns 23 located inside the three arc-shaped grooves to move. Then, the three fixed clamping plates 12 are moved by the three horizontal plates 22 and the three sliding plates 21, causing them to extend outward. Then, the cup is placed on top of the main frame 11. The pull ring 29 is released. The elastic effect of the two return springs 212 causes the rack 27 to move, which in turn drives the gear 26 to mesh and rotate, causing the rotating disk 25 to rotate as well. This causes the three moving columns 23 to move as well, causing the three fixed clamping plates 12 to retract towards the center position, thus fixing the cup placed on top of the main frame 11. This allows the device to fix cups of different sizes, effectively improving the applicability of the cup holder. When the suction of the fixed suction cup 32 decreases after a period of use and needs to be replaced, press the two limiting blocks 34 through the two limiting slots 35 to press the two limiting blocks 34 from the limiting slots 35 to the inside of the main frame 11. At this time, the limiting effect between the main frame 11 and the circular base plate 31 can be canceled. Then the circular base plate 31 can be removed from the bottom of the main frame 11, and a new fixed suction cup 32 can be replaced. Then press the main frame 11 on top of the circular base plate 31. The elasticity of the elastic piece 33 will press the limiting blocks 34 into the inside of the main frame 11. When the main frame 11 is pressed into contact with the circular base plate 31, the limiting blocks 34 will pop out from the limiting slots 35 through the elasticity of the elastic piece 33, thereby fixing the main frame 11 and the circular base plate 31, thus completing the replacement of the fixed suction cup 32. The operation is simple and effectively improves the convenience of using the cup holder.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
