Detailed Description

As shown in fig. 1, fig. 3, fig. 4 and fig. 5, the waterproof case without the fastening piece of the present invention includes an upper case 1 and a lower case 2 corresponding to each other, and the upper case 1 and the lower case 2 are designed to have a square and circular arc shape as a whole, which is simple and beautiful. Go up 1 lateral wall inboard of casing and open and to have a plurality of

bayonets

101, 2 lateral wall outside circumference of casing is provided with the column arch 201 that suits with bayonet 101 down, protruding 201 surface is the arc. Through bayonet socket, the protruding connection of mutually supporting between last casing 1 and the lower casing 2, the no fastener mode of no penetrability opening like this and penetrability trompil can block, conveniently unpack apart again, and the opening and shutting is convenient, can open and shut many times. In order to facilitate the detachment of the upper and lower cases, as shown in fig. 1 and 6, an opening groove 102 is formed on a sidewall of the upper case where the upper case 1 contacts the lower case 2, so that the case can be easily opened by inserting a driver of a "straight" type into the groove 102 and rotating the driver. In order to realize the integral waterproof of the shell, a sealing ring clamping groove 209 is formed in the side wall of the lower shell 2 below the protrusion 201, and a sealing ring 210 is clamped in the sealing ring clamping groove 209.

In the embodiment, the waterproof shell is used as the shell of the water immersion sensor in the internet of things. As shown in fig. 2, the bottom surface of the lower case 2 is provided with a convex contact plane 203, enabling convenient and stable placement. The periphery of the water tank is provided with annular steps, so that the water tank is more favorable for water flowing around. The contact plane 203 is provided with a first groove 204 which can be used for installing a magnet, a rubber pad and a sticker, the magnet is installed to facilitate magnetic attraction on a metal surface, and the magnet can be horizontal, inclined and vertical; the installation rubber pad increases surface friction, is difficult for sliding at will when placing, can place on glossy object surface, also can place on the little plane of inclination, and the installation sticker conveniently pastes on non-metallic surface (for example, surfaces such as glass, plastics, ceramic tile, timber), but the level, but the inclined plane, but the vertically. The probe 202 is connected to the lower housing 2 below the contact plane 203, so that the two probes are more conveniently contacted with water, and a water path cannot be formed when the water is not much.

As shown in fig. 3 and 4, the middle of the upper shell 1 is circular, concave, thick at the periphery and thin at the middle, and the design of the square enables the middle position of the upper shell 1 to be more easily deformed, thereby facilitating the pressing of fingers. The outer convex bayonet 207 used for installing and fixing the PCB is arranged on the side wall of the lower shell 2 along the corner, the button is designed in the middle of the PCB, and the button is opened or closed or is operated by pressing the middle position of the upper shell, so that the function of the button can be realized, the opening without penetration and the opening without penetration are realized, and the integral waterproof design is realized. The lower case 2 is provided with a battery groove 205 inside, and the battery groove 205 helps to stabilize the battery fixedly mounted on the PCB. In order to observe the indicator conveniently, the upper cover is provided with a light-transmitting position at a position corresponding to the PCB indicator (one or more indicator lamps can be arranged on the PCB), and the upper cover is provided with a light-transmitting position with a smaller diameter and a thinner thickness (the specific value of the thickness is determined according to the light-transmitting property of the material of the upper cover, the better the light-transmitting property is, the thicker the light-transmitting property is, and the light-transmitting position does not need to be specially designed if the light-transmitting property is good enough). A second groove 206 is formed in the lower case 2 beside the battery slot 205, and the second groove 206 can be used for placing magnet guiding sheets and can also be used for reserving more space for other electronic components. The inner side of the side wall of the lower shell 2 is circumferentially provided with a shrinkage-proof groove 208, so that shrinkage marks can be prevented from being generated during injection molding.

This patent application can be different according to the function of PCB board, and final design is for can waterproof SOS button, also can design the portable button for wireless control lamp, also can design into outdoor waterproof wireless control button, can also become waterproof water logging sensor, perhaps designs for the controller of other equipment etc. and such transform is all within the protection scope of this patent application.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many variations or modifications may be made to the embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims.
