[0034] Embodiment

[0035] Refer to Figure 1 As shown, this embodiment provides a height adjustment device for a disc button base, including a backing plate 1, a lead screw 2, an adjustment seat 3, an adjustment member 4 and a drill 5. The lead screw 2 is connected to the backing plate 1, and specifically, the lead screw 2 and the backing plate 1 are connected by welding. The adjustment seat 3 includes a connection ring 31 and an operation ear 32; the connection ring 31 is threadedly sleeved on the lead screw 2, and the height adjustment of the adjustment seat 3 can be realized by relatively rotating the lead screw 2 and the adjustment seat 3. Two operation ears 32 are connected to the circumferential side surface of the connection ring 31, and the two operation ears 32 are symmetrically arranged. The adjustment member 4 includes an adjustment sleeve 41 and a connecting rod 42; one end of the adjustment sleeve 41 is provided with a card slot 45 for engaging with the operation ear 32, and the other end is connected to the connecting rod 42.

[0036] In a conventional disc button base structure, the number of operation ears 32 is generally two. In other special embodiments, the number of operation ears 32 can also be multiple, and correspondingly, a corresponding number of card slots 45 are provided on the adjustment sleeve 41.

[0037] The drill 5 clamps the connecting rod 42. By turning on the drill 5 to drive the connecting rod 42 to rotate, the adjustment sleeve 41 can be driven to rotate, so as to drive the adjustment seat 3 to rotate under the cooperation of the card slot 45 and the operation ear 32, realizing height adjustment.

[0038] It should be noted that the drill 5 itself can clamp the corresponding drill rod. In this embodiment, a drill rod is selected as the connecting rod 42, and the drill rod is welded to the adjustment sleeve 41. When in use, the drill 5 clamps the drill rod. When storing, the drill rod is separated from the drill 5, so that the drill 5 is separated from the adjustment sleeve 41, which is convenient for storage and does not affect the use of the drill 5 in other aspects.

[0039] The height adjustment device of the buckle base provided in this embodiment is a device in which a sleeve is sleeved on the screw rod 2, so that the slot 45 is engaged with the operating ear 32, and the electric drill 5 is used to clamp the connecting rod 42, and the electric drill 5 can be used to drive the adjustment seat 3 to rotate to achieve height adjustment, which is more time-saving and labor-saving than direct human adjustment, and improves the efficiency of construction. In addition, during the operation, the slot 45 can be directly engaged with the operating ear 32 to achieve transmission, which is simple and convenient.

[0040] Specifically, refer to Figure 2 As shown, the adjustment sleeve 41 includes an adjustment sleeve body 43 and an enlarged head 44 connected to the adjustment sleeve body 43; the diameter of the enlarged head 44 gradually increases in the direction away from the adjustment sleeve body 43; the clamping groove 45 is provided at one end of the enlarged head 44 away from the adjustment sleeve body 43. There are four clamping grooves 45 arranged at equal angles at the end of the enlarged head 44, and the width of the clamping groove 45 can be set to be slightly larger than the width of the operating ear 32, so as to facilitate the clamping of the clamping groove 45 with the operating ear 32. By providing the enlarged head 44, the size of the adjustment seat 3 can be adapted, thereby reducing the diameter of the adjustment sleeve 41 in disguised form, reducing consumables and weight.

[0041] Specifically, refer to Figure 3 As shown, a base 6 is also provided. The base 6 includes a bottom plate 61 and a stopper 62, the stopper 62 is connected to the bottom plate 61, and the pad 1 is detachably connected to the stopper 62. The stopper 62 includes three stopper blocks connected end to end. The three stopper blocks are arranged in a "凵" shape; the stopper 62 is provided with a stopper groove 63 for accommodating the edge of the pad 1 to be inserted. The pad 1 is a rectangular structure, and an opening is formed on one side of the stopper 62. The pad 1 can be inserted into the stopper groove 63 from the opening, so as to realize the connection between the base 6 and the pad 1, and the screw rod 2 extends outward from the middle of the stopper 62. By providing the base 6, the counterweight of the screw rod 2 can be increased, and the friction area with the ground can be increased, so that the screw rod 2 can be kept stable when the adjustment seat 3 is adjusted. And by cooperating with the stopper 62 in the shape of the "凵" character and the pad 1, the relative rotation of the pad 1 and the base 6 can also be limited.

[0042] Specifically, refer to Figure 4 As shown, a protective sleeve 7 is also provided at the top of the screw rod 2. The protective sleeve 7 is sleeved on the end of the screw rod 2 away from the backing plate 1; a bearing 71 is sleeved on the protective sleeve 7; and the adjusting sleeve 41 is sleeved on the outside of the bearing 71. By sleeve-fitting the adjusting sleeve 41 on the outside of the bearing 71, the positioning of the adjusting sleeve 41 is achieved, so that one end of the adjusting sleeve 41 is positioned by cooperating with the operating ear 32, and the other end is positioned by the bearing 71, so as to prevent the rotation axis from deflecting during the process of the electric drill 5 driving the adjusting member 4 to rotate, and to protect the thread on the surface of the screw rod 2.

[0043] Specifically, the protective sleeve 7 includes a barrel wall and a bottom wall; the barrel wall is sleeved on the lead screw 2, and the bottom wall is connected to the end of the barrel wall. A threaded hole is provided at one end of the lead screw 2 away from the backing plate 1, so that the bottom wall is connected to the end of the lead screw 2 away from the backing plate 1 through a bolt 72. This can ensure the stability of the protective sleeve 7 during the adjustment process and make the positioning more reliable.

[0044] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0045] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
