[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] See also Figures 1 to 5, which is a toilet cover lower lock quick-install structure as the best embodiment of the utility model, includes a base 10, a bolt 20 pre-placed in the lower section of the base 10, and a nut assembly 30 matched with the bolt 20. The base 10 is provided with a connecting mechanism 40 that can be connected to the toilet cover. The nut assembly includes a locking seat 31 and a limiting ring 32 that can be sleeved on the outer peripheral side of the bolt 20. The upper end of the locking seat 31 is provided with a plurality of movable pieces 33 distributed along the circumferential direction, and there is a gap 34 between adjacent movable pieces 33. The locking seat 31 and the plurality of movable pieces 33 are axially penetrated to form a quick sliding groove 35 that matches the bolt 20 and is slightly larger than the outer diameter of the bolt 20. The quick sliding groove 35 is formed by the locking seat 31 and the plurality of movable pieces 33. The speed sliding groove 35 is provided with an internal thread 36 that cooperates with the external thread 21 of the bolt 20 on the inner side of the plurality of movable pieces 33. The middle part of the limiting ring 32 has a limiting hole 321 that can be slidably connected with the bolt 20. The cylindrical area enclosed by the plurality of movable pieces 33 forms a minimum outer diameter R1 at its top end away from the locking seat 31. The inner diameter R2 of the limiting hole 321 is adapted to the minimum outer diameter R1 of the plurality of movable pieces 33 so that when the movable piece 33 is pushed into the limiting hole 321, it is squeezed to abut against the external thread 21 of the bolt 20. In this embodiment, R1 is slightly smaller than R2, specifically R1=R2-a, and 0.05mm≤a≤0.1mm.

[0030] Preferably, Figure 2 , 3 As shown in Figure 4, an inclined guide surface 37 is formed on the outer side of the movable piece 33, and the guide surfaces 37 of several movable pieces 33 are enclosed to form a truncated cone with a smaller bottom surface facing the limiting ring 32 side. The minimum outer diameter R1 of the upper end of the truncated cone area enclosed by several movable pieces 33 is slightly smaller than the inner diameter R2 of the limiting hole 321, and the maximum outer diameter of the lower end is larger than the inner diameter of the limiting hole 321. The design of the guide surface 37 of the movable piece 33 is conducive to the smooth assembly of the nut assembly 30, that is, the inclined guide surface 37 is formed on the outer peripheral side of several movable pieces 33, so that when the movable piece 33 follows the locking seat 31 to push into the limiting ring 32, each movable piece 33 contacts the limiting hole 321 of the limiting ring 32 along the inclined direction of the guide surface 37, and under the pressure of the side wall of the limiting hole 321, each movable piece 33 gradually elastically deforms in a direction close to each other, so that the inner diameter of the quick slide groove 35 is reduced and the internal thread 36 is threadedly connected with the outer thread 21 of the bolt 20.

[0031] Preferably, Figure 3 , 4 As shown, the opening edges of the limiting ring 32 located at the upper and lower sides of the limiting hole 321 are provided with arc guide angles 322, so as to guide the pressing process of the movable piece 33 and make it press-in smoother.

[0032] Preferably, Figure 2 , 3As shown, a toggle portion 38 is formed at the lower end of the locking seat 31 and is symmetrically distributed along its radial direction. Both sides of the middle part of the toggle portion 38 protrude outward to form a protrusion 381. The quick slide groove 35 passes through the top of the movable sheet 33 to the bottom of the protrusion 381. The setting of the toggle portion 38 is convenient for the user to manually operate the nut assembly 30.

[0033] Preferably, Figure 5 As shown, a clamping block 50 is provided at the upper end of the bolt 20, and one side of the base 10 is recessed inward to form a clamping groove 11 that slidably cooperates with the clamping block 50. The lower end of the clamping groove 11 passes through the bottom surface of the base 10 for the lower end of the clamping block 50 and the bolt 20 to pass through. The clamping block 50 is T-shaped and has clamping edges 51 symmetrically formed on both sides. Side grooves 12 that cooperate with the clamping edges 51 are formed on both sides of the clamping groove 11. Therefore, through the cooperation between the clamping block 50 and the clamping groove 11, the relative fixation between the base 10 and the bolt 20 is ensured, and the stability of the overall structure is improved.

[0034] Preferably, Figure 5 As shown, a limit cover 60 is sleeved on the outer side of the lower end of the base 10, and a limit groove 61 is formed on the upper side of the limit cover 60 to be engaged with the outer peripheral side of the bottom of the base 10. An adjustment hole 62 for the screw to pass through is formed at the bottom of the limit groove 61. The adjustment hole 62 is in the shape of a long strip. The extension length of the block 50 is less than the slot 11 to achieve the position adjustment of the screw on the adjustment hole 62. The design of the limit cover 60 not only plays a positioning role, but also allows the bolt 20 to be fine-tuned within a certain range, thereby enhancing the adaptability of the device. The quick-install structure is compact as a whole and quick to install, which greatly improves the user experience and maintenance convenience.

[0035] Preferably, Figure 5 As shown, the connecting mechanism 40 is integrally formed with the base 10 and includes a connecting seat 41 fixed to the upper end of the base 10, and a connecting shaft 42 protruding horizontally along one side of the top of the connecting seat 41 and used for hinged connection with the toilet cover.

[0036] The beneficial effects of the utility model are as follows:

[0037] The utility model forms a quick sliding groove 35 which is slightly larger than the outer diameter of the bolt 20 on the inner side of the locking seat 31 and the plurality of movable pieces 33, so that the locking seat 31 and the plurality of movable pieces 33 can be quickly pushed to the installation position on the lower side of the ceramic layer of the toilet seat, and cleverly utilizes the interaction between the movable piece 33 and the limiting ring 32 to achieve quick installation and locking of the nut assembly 30, greatly simplifying the operating steps, and is particularly suitable for installation and maintenance in a bathroom environment with limited space.

[0038] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
