What are the technical elements of the toilet cover convenient device?

The installation structure of the toilet cover overcomes the disadvantages of the existing cover installation device of complex structure, high production cost, and low cost performance; it provides the industry with a more convenient way of installation and disassembly of the toilet cover installation. The shaft is installed in a way of inserting blocks and clamping and fixing, and a structure with a certain expansion and contraction performance is formed at the end of the shaft to realize the effect of easily installing and removing the toilet cover.
The toilet cover installation device includes two vertical bases with hinged shafts, a sleeved hinged pipe, and two hinged blocks. The hinge pipe is a hollow round pipe with dampers at both ends. The damper is connected with a hinge block on one side of the hinge pipe, and the two hinge blocks are connected and fixed by a spring. Two through holes are formed in the lower part of the hinge pipe, and the hinge shaft of the base is inserted into the through holes to connect and fix. The hinge block is a block-shaped piece, which is a partial cylinder with a "D" shape in cross section, and has a plane section parallel to the generatrix of the cylinder. A perforation is generated perpendicular to the plane section and along the diameter direction of the cylindrical section, and the diameter of the perforation gradually expands downward from the plane section. The position of the perforation is inside the through hole of the hinge pipe. The hinged shaft of the base is a cylinder, and its open end forms a shuttle-shaped expansion ring, which is divided into at least two parts by a radial slot. Or, the open end expansion ring of the hinged shaft cylinder of the base is formed into a circular ring structure.
The hinge pipe is installed between the two installation ear parts on one side of the toilet cover, and the damper is inserted into the ear parts. The spring in the hinge pipe pushes the combination of the hinge block and the damper at both ends outward, so that the damper and the ear part are firmly fixed. At the same time, the perforations of the two hinge blocks are respectively aligned with the left and right through holes of the hinge pipe, and a hinge shaft of the base is provided for installation. The base is installed on the toilet, the two through holes of the hinge pipe are respectively sleeved on the hinge shaft of the base at the same time, and the toilet cover is pressed to make the truncated cone-shaped expansion ring at the end of the hinge shaft pass through the through hole of the hinge block and stay On the plane section of the hinge block. Since the outer diameter of the expansion ring is larger than the diameter of the through hole, the hinge shaft is stuck by the hinge block and cannot be removed. In this way, the quick installation of the toilet cover is completed. When you need to remove the toilet cover, make the toilet cover vertical and pull it upward. After the end of the hinge shaft is squeezed by the through hole, its various parts are bent in the radial direction, and the cone-shaped expansion ring shrinks inward. It becomes smaller and can fade down from the flat cut surface along the through hole, so as to realize the purpose of separating the toilet cover from the base. It can be seen that the installation device of the present utility model simplifies the installation structure of the toilet cover, is very convenient to install and disassemble, has increased practicability, and improves the cost performance of the toilet cover product.
