Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-5 This utility model provides an embodiment of a coffee table with retractable casters, including a main rod 1 and support legs 5. The bottom end of the main rod 1 is provided with a retractable caster assembly, which includes a screw 2, a screw sleeve 3, a base 4, support legs 5, an anti-slip pad 6, a movable platform 7, a bottom groove 8, and a caster body 9. The bottom end of the main rod 1 is fixed with a screw 2, and a screw sleeve 3 is provided on the outer side of the screw 2. The surface of the screw 2 is provided with external threads, and the inside of the screw sleeve 3 is provided with internal threads. The bottom end of the screw sleeve 3 is fixed with a base 4, and the bottom end of the outer wall of the base 4 is fixed with a support leg 5. The bottom end of the support leg 5 is fixed with an anti-slip pad 6. The bottom end of the screw 2 is installed with a movable platform 7, and the surface of the bottom end of the movable platform 7 is provided with a bottom groove 8. Four sets of bottom grooves 8 are provided on the surface of the bottom end of the movable platform 7, and the four sets of bottom grooves 8 are symmetrically distributed. The caster body 9 is movably installed inside the bottom groove 8. Specifically, such as Figure 1 and Figure 3 As shown, when in use, rotating the screw sleeve 3 will cause the base 4 to move upward. As the caster body 9 on the bottom side of the moving platform 7 contacts the ground, the caster body 9 can help the coffee table move. Conversely, rotating the screw sleeve 3 in the opposite direction will drive the base 4 to move downward. When the outer support leg 5 contacts the ground, it will cooperate with the anti-slip pad 6 to help fix the coffee table in position. The top of the main rod 1 is provided with a socket 10, the bottom of the outer wall of the socket 10 is provided with a fixing hole 11, the inside of the fixing hole 11 is provided with a fixing bolt 12, and the top of the outer wall of the socket 10 is fixed with a reinforcing rib 13. Specifically, such as Figure 1 and Figure 4 As shown, when in use, after loosening the fixing bolt 12 on the outside of the socket 10, the socket 10 will separate from the top of the main rod 1, and the disassembly of the tabletop 14 can be completed. After putting the socket 10 on the bottom side of the tabletop 14 onto the top of the main rod 1, tighten the fixing bolt 12 on the outside, and the installation of the tabletop 14 can be completed. A tabletop 14 is installed at the top of the socket 10. An extension plate 15 is movably installed on the outer side of the tabletop 14. Several extension plates 15 are movably installed on the outer side of the tabletop 14, and the several extension plates 15 are arranged in a ring. A sliding groove 16 is provided on the outer wall of the tabletop 14. A guide groove 17 is provided at the top of the sliding groove 16. An adjusting block 18 is movably installed inside the guide groove 17. An auxiliary hole 19 is provided at the top of the adjusting block 18. A slider 20 is movably installed inside the sliding groove 16. The bottom end of the adjusting block 18 is fixedly connected to the top end of the slider 20. A pin 21 is fixed on the right side of the slider 20. A slot 22 is provided on the inner side wall of the extension plate 15. The right side of the pin 21 extends into the inside of the slot 22. A spring 23 is installed on the left side of the slider 20. Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, in use, by adjusting the slider 20 with the help of the adjusting block 18, the pin 21 is separated from the slot 22, the support and fixation of the expansion plate 15 can be loosened, the expansion plate 15 can be flipped down, and the storage operation of the expansion plate 15 can be completed.

[0017] Working principle: When in use, the caster body 9 at the bottom of the moving table 7 contacts the ground, and the caster body 9 can assist the coffee table in moving to the desired position. After moving to the desired position, the base 4 can be rotated. With the screw sleeve 3 and screw 2 threaded together, the base 4 is driven to move down. When the outer support foot 5 contacts the ground, it cooperates with the anti-slip pad 6 to help fix the coffee table in position. At this time, after flipping the extension plate 15 upward to be flush with the tabletop 14, the pin 21 is inserted into the slot 22 on the inner side of the extension plate 15. With the help of the pin 21, the extension plate 15 is supported and fixed. It cooperates with the tabletop 14 to form a complete tabletop for use. Conversely, if the pin 21 is disengaged from the slot 22, the support and fixation of the extension plate 15 is released, and the extension plate 15 is flipped downward, the extension plate 15 can be stored.

[0018] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
