[0023] 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 efforts shall fall within the protection scope of the utility model. Embodiment

[0024] See Figure 1 and Figure 2As shown in the figure, a toilet lid hinge with a plastic protection layer includes a hinge skeleton 1 and a plastic protection layer 2. The outer surface of the hinge skeleton is co-injected and molded with the plastic protection layer. During processing, the hinge skeleton is formed by stamping a metal strip, specifically a stainless steel structure. Since it is an integral part, the strength of the entire structure can be ensured. At the same time, the thickness of the plastic protection layer can be set according to needs to meet the usage requirements in different situations. And the plastic protection layer can be a lead plastic structure mixed with nylon material and fiber. In this embodiment, the co-injection molding is a conventional processing operation of the existing technology, that is, the plastic protection layer is co-injected and molded on the outer surface of the hinge skeleton. It can ensure the connection stability and reliability at the connection, and is also beneficial to improving the usage effectiveness.

[0025] In the actual application process, the hinge skeleton includes a vertical support plate 11, an arc support plate 12, and a horizontal connection plate 13; and one end of the arc support plate is integrally formed at the top of the vertical support plate, and the other end is integrally formed at the end of the horizontal connection plate; the vertical support plate, the arc support plate, and the horizontal connection plate are all co-injected into the plastic protection layer. The extension lines of the vertical support plate and the horizontal connection plate are set at an angle of 80 - 100 degrees.

[0026] In the actual application process, at least one positioning installation hole 3 is provided on the horizontal connection plate. An installation hole position 4 is integrally formed at the end of the vertical support plate. The installation hole position is an oval hole. During installation, the positioning installation hole is connected to the toilet lid, and the installation hole position is connected to the toilet body for installation. During use, the toilet lid rotates around the installation hole position. During rotation, the hinge skeleton will produce a certain deformation, while the plastic protection remains fixed, which is beneficial to improving the stability effect of use. At the same time, it can also prevent wear at the connection of the toilet lid or the toilet, which is beneficial to improving the service life.

[0027] The utility model has positive effects: The structure of the utility model is reasonably arranged. By setting the hinge skeleton and co-injecting and molding the plastic protection layer on the outer surface of the rubber material skeleton, it is beneficial to reduce costs, and can also reduce the damage caused by the hinge skeleton during use, which is beneficial to improving the usage stability and reliability;

[0028] And it is provided with positioning installation holes in cooperation with the installation hole positions, which also facilitates the installation and connection operations and improves the installation convenience. Embodiment

[0029] See Figure 3 And Figure 4 As shown in the figure, this embodiment is basically the same as Embodiment 1, the difference being that: a wire channel 5 is provided inside the hinge skeleton; a power cord is co-injected on the plastic protection layer. Through the above structure, the connection stability and reliability of the power cord can be ensured.

[0030] Meanwhile, it is provided with a wire channel inside the hinge skeleton and is matched with a co-injected power cord, which is also beneficial to improving the stability and reliability of power connection. At the same time, it can also prevent the wear at the connection of the power cord, and has strong practicability.

[0031] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification, they can also be directly processed without doubt according to the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0032] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
