Description

Technical Field

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

[0002] Most existing cups have a cylindrical structure and a simple bottom design. When placed on a table, the cup is easily dropped due to collisions or shaking, making it very unsafe and inconvenient to use. Utility Model Content

[0003] One of the objectives of this utility model is achieved through the following technical solution:

[0004] A cup-fixing device includes a circular base. Three grooves are evenly distributed on the inner wall of the circular base, and a swing rod is inserted into the inner cavity of each of the three grooves. A movable shaft is fixedly connected through each of the three swing rods, and both ends of the movable shaft are rotatably connected to the inner wall of the groove. A coil spring is provided on each of the three movable shafts. A rubber ball is fixedly connected to the other end of each of the three swing rods. An annular plate is slidably fitted onto the outer wall of the circular base, and three sliders are evenly fixedly connected to the inner wall of the annular plate. A groove corresponding to the slider is formed on the outer wall of the circular base. The three sliders are slidably connected to the inner cavities of adjacent grooves. A return spring is provided in the inner cavity of each of the three grooves, and the upper and lower ends of the return spring are fixedly connected to the slider and the bottom of the groove cavity, respectively. A pressure rod is attached to the top of each of the three swing rods, and an L-shaped rod is fixedly connected to one side of each pressure rod. The other ends of the three L-shaped rods are fixedly connected to the top of the annular plate. A circular support plate is provided at the center of the inner cavity of the circular base, and a lifting mechanism is provided at the bottom of the circular support plate.

[0005] Furthermore, the lifting mechanism includes two connecting rods, one end of which is hinged to the left and right sides of the bottom of the circular support plate, and the other end of each connecting rod is hinged to a rectangular block. The bottom of the inner cavity of the circular base is provided with a rectangular groove that matches the rectangular block, and the two rectangular blocks are slidably connected to the inner cavity of the rectangular groove. The two rectangular blocks are provided with threaded holes with opposite thread directions, and the inner cavities of the two threaded holes are threaded with the same threaded rod. The left end of the threaded rod is rotatably connected to the left side of the inner cavity of the rectangular groove. The right side of the circular base is provided with a through hole that communicates with the inner cavity of the rectangular groove, and the right end of the threaded rod passes through the inner cavity of the through hole and is fixedly connected to a rocker arm.

[0006] Furthermore, a rubber coaster is fixedly connected to the top of the circular tray.

[0007] Furthermore, the circular support plate is fixedly connected to the left and right sides with limiting rods, and the inner cavity of the circular base is provided with limiting grooves on the left and right sides that are adapted to the limiting rods, and the two limiting rods are respectively inserted into the inner cavity of the adjacent limiting grooves at opposite ends.

[0008] Furthermore, several suction cups are evenly fixedly connected to the bottom of the circular base.

[0009] Furthermore, a toggle ring is fitted and fixed at the bottom of the outer wall of the annular plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. By lifting the actuating ring, the annular plate can be moved upward against the resistance of the return spring. This allows the L-shaped rod to move the pressure rod away from the swing rod. Consequently, the swing rod, under the action of the spring's rebound force, moves the rubber balls away from the center of the inner cavity of the circular base. When the user places the cup into the rubber coaster inside the circular base, releasing the actuating ring allows the annular plate to slide downward under the rebound force of the return spring. The L-shaped rod then moves the pressure rod to press the swing rod downward, thus securing the cup with the three rubber balls and improving the ease of cup fixation.

[0012] 2. By turning the rocker arm, the threaded rod can be rotated, which in turn causes the two rectangular blocks to move relative to each other or away from each other. Thus, the height of the circular tray can be vertically adjusted via the connecting rod, making it easier to pick up and put down the cup. Attached Figure Description

[0018] A cup-fixing device includes a circular base 1. Three grooves 2 are evenly distributed on the inner wall of the circular base 1, and a swing rod 3 is inserted into the inner cavity of each of the three grooves 2. A movable shaft 5 is fixedly connected through each of the three swing rods 3, and both ends of the movable shaft 5 are rotatably connected to the inner wall of the groove 2. A coil spring 6 is provided on each of the three movable shafts 5. A rubber ball 4 is fixedly connected to the other end of each of the three swing rods 3. An annular plate 9 is slidably fitted onto the outer wall of the circular base 1, and three sliders 10 are evenly fixedly connected to the inner wall of the annular plate 9. The outer wall is provided with a groove 11 corresponding to the slider 10. The three sliders 10 are slidably connected to the inner cavity of the adjacent groove 11. The inner cavity of each of the three grooves 11 is provided with a return spring 12. The upper and lower ends of the return spring 12 are fixedly connected to the bottom of the slider 10 and the inner cavity of the groove 11, respectively. The top of each of the three swing rods 3 is fitted with a pressure rod 7. One side of the pressure rod 7 is fixedly connected with an L-shaped rod 8. The other end of each of the three L-shaped rods 8 is fixedly connected to the top of the annular plate 9. A toggle ring 13 is sleeved and fixed at the bottom of the outer wall of the annular plate 9.

[0019] A circular support plate 15 is provided at the center of the inner cavity of the circular base 1, and a lifting mechanism is provided at the bottom of the circular support plate 15. A rubber cup pad 16 is fixedly connected to the top of the circular support plate 15, which can provide elastic support for the cup. It can be raised and lowered by pulling the actuating ring 13, thereby driving the three pressure rods 7 to rise and fall vertically, which can realize the gathering and dispersing of the three rubber balls 4, so as to improve the convenience of fixing and relaxing the cup. Several suction cups 14 are evenly fixedly connected to the bottom of the circular base 1 to improve the stability of the circular base 1 when placed on the table.

[0020] The lifting mechanism includes two connecting rods 17, one end of which is hinged to the left and right sides of the bottom of the circular support plate 15, respectively. The other end of each connecting rod 17 is hinged to a rectangular block 18. A rectangular groove adapted to the rectangular block 18 is formed at the bottom of the inner cavity of the circular base 1, and both rectangular blocks 18 are slidably connected to the inner cavity of the rectangular groove. Threaded holes with opposite thread directions are formed on each of the two rectangular blocks 18, and the same threaded rod 19 is threaded into the inner cavity of both threaded holes. The left end of the threaded rod 19 is rotatably connected to the left side of the inner cavity of the rectangular groove. A rectangular block 18 is formed on the right side of the circular base 1. The rectangular groove has a through hole that is connected to the inner cavity, and the right end of the threaded rod 19 passes through the through hole and is fixedly connected to the rocker arm 20. Limiting rods 21 are fixedly connected to both the left and right sides of the circular tray 15. Limiting grooves 22 that are adapted to the limiting rods 21 are opened on both the left and right sides of the inner cavity of the circular base 1. The ends of the two limiting rods 21 that are far apart are respectively inserted into the inner cavities of the adjacent limiting grooves 22. This can limit the circular tray 15 when it moves up and down, improve the stability of vertical lifting, and the height of the circular tray 15 can be adjusted by rotating the rocker arm 20, thereby improving the convenience of taking and putting away the cup.

[0021] Working Principle: In use, the suction cup 14 securely attaches the circular base 1 to the tabletop, improving the ease of installation. Pulling the actuating ring 13 causes the annular plate 9 to move upwards against the resistance of the return spring 12. This allows the L-shaped rod 8 to move the pressure rod 7 away from the swing rod 3. Consequently, the swing rod 3, under the restoring force of the coil spring 6, moves the rubber ball 4 away from the center of the inner cavity of the circular base 1. After the user places the cup onto the rubber coaster 16 inside the inner cavity of the circular base 1, releasing the actuating ring 13 allows the annular plate 9 to return under the restoring force of the return spring 12. Slide downwards, and the L-shaped rod 8 drives the pressure rod 7 to press the swing rod 3 downwards, thereby bringing the three rubber balls 4 together. The cup body can then be fixed by the three rubber balls 4, improving the convenience of fixing the cup body. When it is necessary to remove some cups without handles, the rocker arm 20 can be turned to drive the threaded rod 19 to rotate. The rotation of the threaded rod 19 drives the two rectangular blocks 18 to move relative to each other. The relative movement of the two rectangular blocks 18 pushes the circular support plate 15 vertically upwards through the two connecting rods 17, thereby pushing the cup body to the top of the inner cavity of the circular base 1, making it easy to remove the cup body.
