[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0028] like Figure 1-6 As shown, a waterproof timer comprises a main body 1 and a timing mechanism 2 arranged in the main body 1. A waterproof cover 3 is arranged on the main body 1, and the waterproof cover 3 is covered on the main body 1 to isolate the end of the main body 1 from the external space.

[0029] Specifically, a rotating portion 4 is formed on the waterproof cover 3, a rotating shaft 5 is formed on the rotating portion 4, a connecting portion 6 is formed on the main body 1, a rotating hole 7 for inserting the rotating shaft 5 is formed on the connecting portion 6, and a positioning protrusion 101 is formed on the rotating portion 4, a positioning area 102 for inserting the positioning protrusion 101 is formed on the connecting portion 6, and the positioning protrusion 101 is inserted into the positioning area 102 to keep the waterproof cover 3 in the current position.

[0030] By rotating the waterproof cover 3 on the main body 1 and covering the waterproof cover 3 on the main body 1, water or dust can be prevented from entering the main body 1 and damaging the timing mechanism 2. In addition, the positioning protrusion 101 on the rotating part 4 of the waterproof cover 3 cooperates with the positioning area 102 on the connecting part 6 of the main body 1 to keep the waterproof cover 3 in the current position, which not only improves the waterproofness and sealing of the entire timer, but also improves the installation flexibility of the waterproof cover 3, and the waterproof cover 3 will not open automatically.

[0031] like Figure 1-6 As shown, further explanation of the cooperation between the positioning area 102 and the positioning protrusion 101 in this embodiment, the positioning area 102 includes a first positioning groove 103 and a second positioning groove 104, the positioning protrusion 101 is inserted into the first positioning groove 103, and the waterproof cover 3 is in a closed state, and the positioning protrusion 101 is inserted into the second positioning groove 104, and the waterproof cover 3 is in an open state. By utilizing the positioning protrusion 101 to cooperate with the first positioning groove 103 and the second positioning groove 104, the waterproof cover 3 can be fixed at a specified angle, thereby improving the stability of the waterproof cover 3 in the closed state and the open state.

[0032] Preferably, the rotating shaft 5 and the positioning protrusion 101 are integrated, which improves the structural strength of the rotating shaft 5 and the positioning protrusion 101 and improves the reliability of maintaining the position of the waterproof cover.

[0033] like Figure 1-6 As shown, as a further explanation of the implementation method of the waterproof cover 3 in this embodiment, when the waterproof cover 3 is covered on the main body 1, the inner wall of the waterproof cover 3 fits the outer contour of the main body 1. By fitting the inner wall of the waterproof cover 3 to the outer contour of the main body 1, the gap between the waterproof cover 3 and the main body 1 is reduced, thereby preventing water or dust from entering through the gap between the waterproof cover 3 and the main body 1, and greatly improving the sealing performance.

[0034] Preferably, a water-guiding arc surface 113 is formed on the peripheral side of the waterproof cover 3 to guide water so that the water flows along the waterproof cover 3 into the external space.

[0035] In addition, the waterproof cover 3 is covered on the main body 1, and partially extends out of the main body 1 to form a hand-held portion 114. A placement groove 115 for placing a hand is formed at the bottom of the hand-held portion 114. During use by the user, the hand-held portion 114 can be used to rotate the waterproof cover 3, which is more convenient for rotating the waterproof cover 3.

[0036] Preferably, a fixing protrusion 116 is formed on the inner wall of the waterproof cover 3, and a fixing groove 117 for inserting the fixing protrusion 116 is formed on the main body 1. When the waterproof cover 3 is in a closed state, the fixing protrusion 116 is inserted into the fixing groove 117, thereby improving the reliability of the waterproof cover 3 in a closed state.

[0037] like Figure 1-6 As shown, as a further explanation of the implementation method of the main body 1 in this embodiment, the top of the main body 1 has a waterproof step 105 extending upward. Only when the water level above the main body 1 exceeds the waterproof step 105, can water enter the main body 1. Therefore, the waterproof step 105 can further prevent water from entering the main body 1, thereby improving the waterproof performance.

[0038] Specifically, the main body 1 includes an upper shell 108 and a lower shell 109. A plug-in protrusion 110 is formed on the top of the lower shell 109, and a plug-in groove 111 is formed on the bottom of the upper shell 108 for the plug-in protrusion 110 to be inserted into. The plug-in protrusion 110 cooperates with the plug-in groove 111 to improve the convenience of the installation process of the upper shell 108 and the lower shell 109, and improve the sealing performance.

[0039] Furthermore, a waterproof ring 112 is arranged between the plug-in protrusions 110 and the plug-in protrusions 110. The waterproof ring 112 is arranged between the plug-in protrusions 110 and the plug-in protrusions 110. After being squeezed by the upper shell 108 and the lower shell 109, the gap between the upper shell 108 and the lower shell 109 is filled, thereby improving the sealing of the entire main body 1.

[0040] like Figure 5 As shown, in some other embodiments, a lever 106 for adjusting the frequency is provided on the main body 1, and a rotation slot 107 is formed on the main body 1. The lever 106 is placed in the rotation slot 107, and the required frequency can be adjusted according to demand to match the power grids in different regions.

[0041] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
