Description
Technical Field
[0001] The utility model relates to the technical field of mechanical parts, and more specifically, to a foot cup. Background Art
[0002] A foot cup usually consists of a screw rod and a chassis, and is a commonly used mechanical part for adjusting the height of equipment by rotating the thread. At present, most of the existing foot cups rivet the screw rod on the base, and the screw rod is connected to the using equipment with threaded holes. By rotating the thread, the height of the equipment can be adjusted. However, riveting the screw rod to the base requires professional riveting equipment, resulting in high difficulty in the assembly process of the foot cup. After the screw rod is riveted to the base, the contact area between the screw rod and the base is large and the contact surface is stressed greatly, resulting in a large frictional force between the screw rod and the base. Therefore, a large force is required to adjust the height of the equipment with the foot cup, and the adjustment is inconvenient. Content of the Utility Model

[0007] A foot cup includes a base and a screw rod. The screw rod is arranged at the top end of the base. A connection groove is opened at the top end of the base. Two universal hemispherical heads are arranged in the connection groove. Bearing grooves are opened at the top ends of the two universal hemispherical heads, and the two bearing grooves correspond to each other. Rotating grooves are opened at the bottom walls of the two bearing grooves, and the two rotating grooves correspond to each other. A T-shaped connection head is fixedly connected to the bottom end of the screw rod, and the T-shaped connection head passes through the two bearing grooves and is rotatably connected in the two rotating grooves.

[0024] Embodiment:
[0025] Please refer to Figures 1-4 , a foot cup, which includes a base 1 and a screw rod 2. The screw rod 2 is arranged at the top end of the base 1. A connection groove 3 is opened at the top end of the base 1. Two universal hemispherical heads 4 are arranged in the connection groove 3. Bearing grooves 5 are opened at the top ends of the two universal hemispherical heads 4, and the two bearing grooves 5 correspond to each other. Rotation grooves 6 are opened at the bottom walls of the two bearing grooves 5, and the two rotation grooves 6 correspond to each other. The bottom end of the screw rod 2 is fixedly connected with a T-shaped connector 7, and the T-shaped connector 7 passes through the two bearing grooves 5 and is rotatably connected in the two rotation grooves 6. A thrust ball bearing 8 is sleeved on the circumferential surface of the T-shaped connector 7, and the thrust ball bearing 8 is located in the two bearing grooves 5.
[0026] In this embodiment, the T-shaped connector 7 at the bottom end of the screw rod 2 is inserted into the thrust ball bearing 8. The two universal hemispherical heads 4 are symmetrically combined and snapped into the tail of the T-shaped connector 7, so that the T-shaped connector 7 is rotatably connected in the two rotating grooves 6. The thrust ball bearing 8 is located in the two bearing grooves 5. Then, the two universal hemispherical heads 4 are installed in the connecting groove 3 to realize the connection between the base 1 and the screw rod 2. The screw rod 2 rotates on the base 1 through the thrust ball bearing 8, and the thrust ball bearing 8 reduces the force required for the screw rod 2 to rotate.
[0027] Specifically, insertion posts 9 are fixedly connected to the closer ends of the two universal hemispherical heads 4, and the two insertion posts 9 are staggeredly distributed. Sockets 10 are formed at the closer ends of the two universal hemispherical heads 4, and the two sockets 10 are staggeredly distributed and respectively matched with the two insertion posts 9.
[0028] In this embodiment, when the two universal hemispherical heads 4 are combined, they are inserted in a staggered manner through the two insertion posts 9 and the two sockets 10, making the combination of the two universal hemispherical heads 4 on the T-shaped connector 7 more stable and convenient.
[0029] Specifically, the two universal hemispherical heads 4 are in interference fit with the base 1 in the connecting groove 3. The connecting groove 3 is hemispherical, and the shape of the two combined universal hemispherical heads 4 matches that of the connecting groove 3.
[0030] In this embodiment, an interference amount is set between the two universal hemispherical heads 4 and the base 1, so that the two universal hemispherical heads 4 can be manually installed in the connecting groove 3 without a riveting press, reducing the process difficulty.
[0031] Specifically, the top end of the thrust ball bearing 8 is in contact with the bottom end of the screw rod 2, and the bottom end of the thrust ball bearing 8 is in contact with the bottom walls of the two bearing grooves 5.
[0032] In this embodiment, balls are arranged inside the thrust ball bearing 8. The bottom end of the screw rod 2 and the bottom walls of the bearing grooves 5 respectively contact the upper and lower ends of the thrust ball bearing 8, converting the sliding friction on the contact surface between the base 1 and the screw rod 2 into rolling friction, reducing the friction force between the two, and thus reducing the force required for the screw rod to rotate.
[0033] Working principle: The T-shaped connector 7 at the bottom end of the screw rod 2 is inserted into the thrust ball bearing 8. The two universal hemispherical heads 4 are symmetrically combined and snapped into the tail of the T-shaped connector 7, so that the T-shaped connector 7 is rotatably connected in the two rotating grooves 6. The thrust ball bearing 8 is located in the two bearing grooves 5. Then, the two universal hemispherical heads 4 are installed in the connecting groove 3 to realize the connection between the base 1 and the screw rod 2. The screw rod 2 rotates on the base 1 through the thrust ball bearing 8, and the thrust ball bearing 8 reduces the force required for the screw rod 2 to rotate, making it more labor-saving for the screw rod 2 to rotate and adjust the height of the equipment.
[0034] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
