[0024] The following specific implementation content provides various different embodiments or examples for implementing the present utility model. Of course, these are only embodiments or examples and are not intended to be restrictive. In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0025] As Figures 1-6An adjustable high-stability foot cup shown in the figure includes a bottom plate 1 and a bracket shell 2 rotatably arranged below the bottom plate 1. A roller 3 is rotatably installed on one side of the lower end of the bracket shell 2. An anchor 4 and a lifting adjustment device are also arranged in the bracket shell 2. The lifting adjustment device is used to drive the anchor 4 to move up and down, and the anchor 4 can extend downward to lift the roller 3. A limit guiding structure for guiding the up and down movement of the anchor 4 is also arranged in the bracket shell 2. The lifting adjustment device includes a vertical screw rod 5 rotatably installed in the bracket shell 2. The vertical screw rod 5 is in threaded cooperation with the anchor 4. A first bevel gear 6 is arranged on the vertical screw rod 5. A self-locking adjustment rod 7 is rotatably installed on one side of the bracket shell 2. A second bevel gear 8 capable of meshing with the first bevel gear 6 is arranged at the inner end of the self-locking adjustment rod 7. During operation, the self-locking adjustment rod 7 arranged on one side of the bracket shell 2 can be rotated, and then the second bevel gear 8 meshes with the first bevel gear 6 to drive the vertical screw rod 5 to rotate. The vertical screw rod 5 is in threaded cooperation with the anchor 4, and then under the action of the limit guiding structure, the anchor 4 can be driven to move up and down. The structure is simple and the adjustment is convenient.

[0026] In addition, the self-locking adjustment rod 7 can be locked or unlocked. When locked, it can be locked and cannot rotate, while when unlocked, it can rotate. Thus, when the equipment vibrates during use through the roller 3, the self-locking adjustment rod 7 will not rotate, that is, the vertical screw rod 5 will not loosen, and the anchor 4 can be stably arranged. Furthermore, the overall seismic resistance is strong and the safety is extremely high.

[0027] See Figures 2-5 As shown in the figure, a support cylinder 21 is horizontally arranged on one side of the bracket shell 2. The self-locking adjustment rod 7 is rotatably arranged in the support cylinder 21.

[0028] Furthermore, the self-locking adjustment rod 7 includes a first rod body 31 and a second rod body 32 arranged coaxially. A square column 33 is arranged at one end of the first rod body 31. A square hole 34 capable of inserting the square column 33 is arranged at one end of the second rod body 32. The second bevel gear 8 is arranged at the other end of the first rod body 31. One end of the second bevel gear 8 meshes with the first bevel gear 6, and the other end abuts against the support cylinder 21. Thus, the second bevel gear 8 can be limited to keep it in a meshing state with the first bevel gear 6.

[0029] The other end of the second rod body 32 extends out of the support housing 2 and is provided with an adjusting knob 35. A spring 36 is arranged between the first rod body 31 and the second rod body 32. The spring 36 is sleeved on the square column 33. A circular ring convex seat 37 coaxial with the second rod body 32 is arranged on the outer side of the support housing 2. A first flange 38 is arranged on the inner wall of the circular ring convex seat 37. A second flange 39 is arranged on the second rod body 32 and located inside the circular ring convex seat 37. A plurality of first locking teeth 310 are evenly distributed along the circumference on the inner wall of the first flange 38. A plurality of second locking teeth 311 are evenly distributed along the circumference on the outer wall of the second flange 39. Under the action of the spring 36, the second locking teeth 311 are engaged into the first locking teeth 310.

[0030] When the self-locking type adjusting rod 7 is in the initial state, since the position of the second bevel gear 8 is defined by the first bevel gear 6 and the support cylinder 21, thus, under the action of the spring 36, the second rod body 32 is kept in an outward state. At this time, the second locking teeth 311 are engaged into the first locking teeth 310, and further, the second rod body 32 cannot rotate, achieving a locked state. However, when unlocking, by pressing the second rod body 32 inward, the second locking teeth 311 are separated from the first locking teeth 310, so that the second rod body 32 can rotate, and under the cooperation of the square column 33 and the square hole 34, the first rod body 31 and the second bevel gear 8 are driven to rotate.

[0031] In order to facilitate driving the adjusting knob 35 to rotate, a notch 41 that can cooperate with a wrench or a screwdriver is arranged at the outer end of the adjusting knob 35. The notch 41 can specifically be an internal hexagonal groove, a cross groove, a flat groove, etc. Thus, when the load of the caster is relatively large, by using a tool to rotate the self-locking type adjusting rod 7, it can save effort and improve efficiency.

[0032] See Figure 2 、 Figure 6 As shown, the first rod body 31 is provided with an external thread, the second bevel gear 8 is provided with a central hole, an internal thread that can cooperate with the external thread is arranged in the central hole, and after the second bevel gear 8 is connected to the first rod body 31, the two are fixed by a pin 51.

[0033] See Figure 1 、 Figure 6 As shown, the limiting and guiding structure includes a vertical sliding groove 61 arranged on the side wall of the floor foot 4, and a guiding flange 62 is arranged on the inner side wall of the support housing 2. The guiding flange 62 is slidably arranged in the vertical sliding groove 61.

[0034] See Figure 2 Figure 6As shown, a through hole 91 runs through the base 4 up and down, and a nut 92 that can be threadedly engaged with the vertical screw rod 5 is embedded at the upper end of the through hole 91; when the vertical screw rod 5 rotates, since the vertical screw rod 5 can only rotate circumferentially and cannot move up and down, when it is threadedly engaged with the nut 92 on the base 4, the base 4 rises or falls under the action of the limit guiding structure.

[0035] In order to improve the stability of the base 4 during support, anti-slip protrusions 71 are provided on the lower end surface of the base 4.

[0036] See Figure 2 、 Figure 4 、 Figure 6 As shown, a wave disk 80 is further provided between the bottom plate 1 and the bracket shell 2, and the bottom plate 1, the wave disk 80 and the bracket shell 2 are connected by connecting rivets 81. A shaft hole 82 is provided at the lower end of the connecting rivet 81, and a shaft head 83 is provided at the upper end of the vertical screw rod 5. The shaft head 83 is rotatably arranged in the shaft hole 82. The structure in which the bottom plate 1, the wave disk 80 and the bracket shell 2 are riveted and connected by the connecting rivet 81 is a conventional existing setting.
