[0007] Further, the dust-proof plugs are recessed at both ends of the rotating bracket.

[0008] Further, an interference fit is provided between the dust-proof plugs and the rotating bracket.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] A waterproof and dustproof electric pedal, as Figure 1 , 2 , shown in Figure 4, includes a fixing plate 1 and a connecting plate 2 rotatably connected to the fixing plate 1; one end of the connecting plate 2 is connected to a support plate 3, and a pedal 4 is arranged on the support plate 3; both ends of the rotating shaft 2-1 of the connecting plate 2 are fixed in the rotating bracket 2-2 of the connecting plate 2; an oil seal 2-3 is arranged at a position close to the connection with the rotating shaft 2-1 inside the rotating bracket 2-2, an oil-free bushing 2-4 is arranged outside the oil seal 2-3, and an oil-free bushing mounting sleeve 2-5 is arranged outside the oil-free bushing 2-4; dust-proof plugs 2-6 are arranged at both ends of the rotating bracket 2-2.

[0024] Specifically, by arranging oil seals 2-3 at both ends of the rotating shaft 2-1, it effectively prevents moisture and dust from invading the internal mechanical structure through the gaps of the rotating shaft. The oil seal not only has good sealing performance but also can resist wear to a certain extent and extend the service life. The design of the oil-free bushing 2-4 and its mounting sleeve 2-5 provides double protection for dust prevention. The oil-free bushing reduces the accumulation of impurities generated by friction, and the mounting sleeve further isolates the external environment, effectively preventing dust and fine particles from entering the rotating shaft area, keeping the inside clean, and the special sequential arrangement structure further improves the convenience during installation and maintenance.

[0025] As a preference of the above embodiment, the dust-proof plugs are recessed at both ends of the rotating bracket 2-2.

[0029] As a preference of the above embodiment, as Figure 1 shown, the connecting plate 2 is driven to rotate by the motor 5.

[0030] As a preference of the above embodiment, as Figure 2 shown, two groups of the fixing plate 1 and the supporting plate 3 are provided.

[0031] Specifically, through two groups of the fixing plate and the supporting plate, the weight of the hot water furnace or other equipment can be more effectively dispersed, the pressure of single-point stress can be reduced, thereby enhancing the stability and safety of the whole structure. At the same time, it can be adjusted according to the actual size of the hot water furnace or other equipment to adapt to equipment of different specifications and models.

[0032] As a preference of the above embodiment, as Figure 2 shown, two of the connecting plates 2 are arranged between the fixing plate 1 and the supporting plate 3.

[0033] Specifically, through the arrangement of two connecting plates 2, the connection points between the fixing plate 1 and the supporting plate 3 are increased, thereby enhancing the firmness and load-bearing capacity of the whole structure.

[0034] As a preference of the above embodiment, as Figure 2 shown, the number of the connecting plates 2 adapts to the change of the number of the fixing plate 1 and the supporting plate 3.

[0035] Specifically, through the structure that the number of the connecting plates 2 adapts to the change of the number of the fixing plate 1 and the supporting plate 3, it is used to be able to adapt to fixing plates and supporting plates of different sizes and shapes, improving the versatility and adaptability.
