Description

Technical Field

[0001] The utility model relates to a footstool, in particular to a threaded lifting and adjusting footstool. Background Art

[0002] When children go to the toilet or wash their hands on the sink, they cannot climb onto the toilet by themselves due to their short stature, and their hands cannot reach the sink, so they need help from their parents and elders. Many parents and elders also want to train their children's independence, so people have invented stepping stools, which children can use to climb onto the toilet, and when sitting on the toilet, they can also step on the stepping stools for support. However, the height of traditional stepping stools is usually fixed, and they cannot be raised or lowered, and they are not suitable for children of different heights, and their versatility is poor. Therefore, some people have applied for an adjustable step stool, such as China Utility Model Patent 201520593553.2, the patent name is "A children's step stool", and China Utility Model Patent 201620135532.0, the patent name is "A liftable toilet step stool". Both of the above patents use a structure of screws and multiple screw holes at different heights. The disadvantage is that each time the height is adjusted, the screw must be unscrewed with a tool, and after adjusting to the specified height, the screw is screwed into the screw hole of the corresponding height. The structure requires the use of tools for adjustment, and the adjustment operation is very troublesome. In addition, someone has applied for Chinese utility model patent 201621138890.3, the name of the patent is "a toilet footstool", which includes a base, a lifting and fixing device is installed on the top of the base, and a pedal is installed on the top of the lifting and fixing device. The pedal can be moved and positioned in the vertical direction under the action of the lifting and fixing device; the lifting device includes an inner tube and an outer tube, the lower end of the inner tube is fixedly installed with the base, the outer edge of the upper end of the inner tube is covered with the outer tube, the upper end of the outer tube is fixedly installed with the lower end face of the pedal, and a plurality of through holes are evenly spaced in the vertical direction on the outer wall of one side of the outer tube, and an elastic block that can be embedded with the through hole is installed in the outer edge of the side wall corresponding to the position of the through hole of the inner tube. However, the disadvantage of this structure is that the elastic block is inserted into the through hole of the inner tube to play a positioning role for the inner tube and the outer tube. The reliability of this structure is poor. Once it is not stuck, children standing on the footstool are easy to fall down, which poses a safety hazard. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a threaded lifting and adjusting footstool which is convenient to operate, stable and reliable to adjust, simple in structure and easy to manufacture.

[0004] The utility model discloses a technical solution of a threaded lifting and adjusting footrest stool, which comprises a stool surface, stool feet are arranged below the two sides of the stool surface, the stool feet are fixed to the stool surface, more than one lifting hole is formed in the stool feet, lifting feet are arranged in each lifting hole, and the lifting feet are matched with the lifting holes through threads.

[0005] Furthermore, a positioning protrusion is formed on the outer wall of the lifting foot, and a positioning groove is formed on the inner wall of the lifting hole, and the positioning protrusion is positioned and matched with the positioning groove.

[0006] Furthermore, the upper and lower sides of the positioning protrusion are hollowed out, and the left and right sides of the positioning protrusion are integrally connected to the lifting foot via connecting ribs.

[0007] Furthermore, an anti-slip pad is provided at the bottom of the lifting foot.

[0021] The utility model relates to a threaded lifting and adjusting footstool. Figure 1 — Figure 8 As shown, it includes a stool surface 1, and stool feet 2 are arranged below the two sides of the stool surface 1. The stool feet 2 are fixed to the stool surface 1. One or more lifting holes 3 are formed in the stool feet 2. Lifting feet 5 are respectively arranged in each lifting hole 3. The lifting feet 5 and the lifting holes 3 are matched through threads 4.

[0022] Furthermore, the outer wall of the lifting foot 5 is formed with a positioning protrusion 7, and the inner wall of the lifting hole 3 is formed with a positioning groove 8, and the positioning protrusion 7 is positioned and matched with the positioning groove 8. With the positioning protrusion 7 and the positioning groove 8, when the lifting foot 5 rotates and descends to the specified position, the positioning protrusion 7 is inserted into the positioning groove 8 and a "click" sound is emitted, indicating that the lifting foot 5 is lifted and lowered into place, and the positioning protrusion 7 and the positioning groove 8 can play a role in positioning the lifting foot 5.

[0023] Furthermore, the upper and lower sides of the positioning protrusion 7 are provided with hollows 9, and the left and right sides of the positioning protrusion 7 are integrally connected to the lifting foot 5 via connecting ribs 10. The hollows 9 are provided between the positioning protrusion 7 and the lifting foot 5, so that they have a certain elasticity, which is conducive to the positioning protrusion 7 being inserted into or removed from the positioning groove 8, and the two will not be easily worn.

[0024] Further, an anti-skid pad 11 is arranged at the bottom of the lifting foot 5. With the anti-skid pad 11, the anti-skid performance of the footstool is improved.

[0025] Furthermore, the stool surface 1 is provided with slots 12 on both sides, the inner wall of the slots 12 is provided with buckle slots 13, a protruding insert block 14 is provided on the upper part of the stool leg 2, a buckle 15 is provided on the side wall of the insert block 14, the stool leg 2 is inserted into the slots 12 through the insert block 14, and the buckle 15 is tightly matched with the buckle slot 13. The stool surface 1 adopts the slots 12 and the buckle slots 13, and the stool leg 2 adopts the protruding insert block 14 and the buckle 15, which is convenient to install and reliable to assemble.

[0026] Furthermore, a reinforcing sheet 16 is formed on the inner wall of the slot 12. With the reinforcing sheet 16, the structural strength of the slot 12 is improved.

[0027] Furthermore, an upper arc groove 17 is formed on one side of the stool surface 1. The upper arc groove 17 can correspond to the curvature of the outer wall of the toilet, so that it can fit the toilet, play a positioning role, and place it more reliably. The upper arc groove 17 reduces the materials used in manufacturing and reduces the manufacturing cost while ensuring the structural strength of the stool surface 1.

[0028] Furthermore, a lower arc groove 18 is formed under the stool leg 2. The lower arc groove 18 reduces the materials used in manufacturing and reduces the manufacturing cost while ensuring the structural strength of the stool leg 2.

[0029] The utility model discloses a threaded lifting and adjusting step stool, two or four stool legs 2 can be set at the lower part of both sides of the stool surface 1. When two stool legs 2 are set, two lifting holes 3 need to be opened in each stool leg 2. When four stool legs 2 are set, one lifting hole 3 is opened in each stool leg 2. The inner wall of the lifting hole 3 is formed with a thread 4. A lifting foot 5 is set in each lifting hole 3. The outer wall of the lifting foot 5 is formed with a corresponding thread 4. When the height of the step stool is to be adjusted, people can directly rotate the four lifting feet 5 by hand. The lifting foot 5 and the lifting hole 3 are lifted and lowered through the thread 4. The four lifting feet 5 are rotated to the required height (the lifting heights of the four lifting feet 5 must be consistent, otherwise the step stool will be unstable). This scheme is a threaded lifting and adjusting step stool, the lifting foot 5 is rotated and matched with the lifting hole 3 through the thread 4, no tools are required, and it can be directly rotated manually. It is easy to operate, simple in structure, and easy to manufacture. After being adjusted in place, when children step on it, the thread 4 structure of the four lifting feet 5 will not shrink due to the weight of the child, and the support is stable and reliable.
