DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model. Embodiment 1

[0035] See Figures 1 to 3As shown, a button-removable floor hinge is fixed to the window frame by screws and includes a base 1, a convex shaft 2, a connecting block 3, and a button structure 4. In this embodiment, the base, convex shaft, connecting block, and button structure are all metal structures. Specifically, they can be aluminum structures or stainless steel structures. The thickness of the base can be processed and set as needed. During actual application, when the connecting block is lifted upward by 2 mm, the connecting block can be separated from the base, which helps reduce the lifting distance. The lower diameter of the convex shaft is larger than the upper diameter, thus improving the effectiveness and stability of the disassembly and assembly operations.

[0036] During actual application, a button slot hole 5 that is transparent from top to bottom is provided on the base, and at least one limiting protrusion 6 is fixed to the top of the button slot hole. The limiting protrusion is mainly used to limit the button structure to prevent it from loosening or falling off from above. It can be an n-shaped one provided at the top of the button slot hole or an L-shaped one provided on the top wall of the button slot hole.

[0037] During assembly, the button structure is arranged in the button slot hole; the lower part of the convex shaft is arranged between the end of the button slot hole and the button structure; the top of the convex shaft is fixed to the end of the connecting block, and the connecting block is fixed to the top or bottom edge of the screen window by screws. The length of the button slot hole is greater than the length of the button structure, so the button structure can translate in the button slot hole, and thus can cooperate with the end wall of the button slot hole to realize the clamping and limiting of the convex shaft.

[0038] During actual application, a semi-circular shaft hole 7 is provided at the end of the button slot hole; an arc-shaped abutting groove 8 is provided at the end of the button structure; the lower part of the convex shaft can be rotatably clamped between the semi-circular shaft hole and the arc-shaped abutting groove. Through the cooperation of the above-mentioned semi-circular shaft hole and arc-shaped abutting groove, the normal rotation of the convex shaft can be ensured, and the effectiveness of the screen window opening and closing operations can be guaranteed.

[0039] In the actual application process, the button structure includes a button member 41, a first spring 42, a second spring 43 and a support plate 44; during assembly, the button member is located within the button slot hole, and the support plate is fixed to the bottom of the button slot hole; the second spring is disposed between the end of the button member and the inner wall of the button slot hole, and the second spring is disposed at one end of the button member away from the convex shaft; the first spring is disposed between the button member and the support plate, and the first spring is disposed on one side of the button member close to the convex shaft; the button member cooperates with the end wall of the button slot hole under the elastic force of the second spring to achieve clamping and limiting of the convex shaft. The first spring can enable the button member to lift a certain distance, and a button operation protrusion 9 is disposed on the top surface of the button member. It can enable the button operation protrusion to lift and cooperate with the limit protrusion for locking. When the button operation protrusion is on the side of the limit protrusion close to the convex shaft, the button member is locked at this time and cannot be translated. When the button operation protrusion is pressed downward to disengage from the limit protrusion, the button member can be translated at this time; while the second spring mainly provides a force so that the end of the button member can abut against the side surface of the convex shaft to ensure the effectiveness of the convex shaft clamping. When disassembling, move it towards the end away from the convex shaft to make the convex shaft in an unclamped state, and then lift it to remove it.

[0040] In the actual application process, a limit rib 10 is provided in the middle of the inner wall of the button slot hole; a abutting protrusion 11 is provided on the symmetric side walls of the button member; the abutting protrusion abuts against the limit rib under the action of the second spring for limiting. Through the above structure, the translation stroke of the button member can be limited to prevent excessive translation.

[0041] In the actual application process, a snap convex column 12 is fixed on the bottom wall of the button slot hole; snap hole positions 13 are fixed at both ends of the support plate; the support plate is located at the bottom of the button slot hole, and the snap convex column is snapped into the snap hole positions for positioning. It improves the disassembly and assembly convenience and installation stability of the support plate.

[0042] The utility model has positive effects: The structure of the utility model is reasonably arranged. The detachable floor and ceiling shaft of the button of the utility model includes a base, a convex shaft, a connecting block and a button structure. When in use, the base is fixed on the window frame, and the connecting block is fixed on the window screen leaf. When in use, only need to lift the window screen leaf a small distance upward, then the convex shaft can be snapped into the base and limited by the button structure. When disassembly is required, translate the button structure backward to separate it from the convex shaft, and then lift the window screen leaf a small distance upward to complete the disassembly operation. Moreover, it is beneficial to reduce its upward lift stroke, so that the window frame can be made thinner. At the same time, it is also beneficial to improve the installation stability and reliability, improve the disassembly and assembly convenience and effectiveness, and there is no need to add a notch on the window frame, which is beneficial to reducing the processing difficulty, improving the processing efficiency, and has strong applicability and good practicability; Embodiment 2
