[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] Reference Figures 1 to 7 As shown, this utility model provides a structure for an automatic lifting button battery door of a waterproof thermometer. In one embodiment, it includes...
[0027] The mounting housing 1 has a first mounting groove 11 on its top, and a first mounting hole for placing a button battery is also provided in the first mounting groove 11; a ring-shaped mounting step 12 is formed between the first mounting hole and the inner wall of the first mounting groove 11.
[0028] The battery cover 2 has a first slot on its outer wall. The first slot includes a first connecting groove 21 that is circumferentially formed on the outer wall of the battery cover 2, and a second connecting groove 22 that is circumferentially formed on the middle of the outer wall of the battery cover 2 and communicates with the first connecting groove 21. The lower part of the first connecting groove 21 extends to the lower edge of the battery cover 2 to form a first notch 23. The end of the first connecting groove 21 away from the second connecting groove 22 also has a first inclined surface 24 that is inclined upward toward the second connecting groove 22.
[0029] The inner wall of the first mounting groove 11 is also provided with a snap-fit strip 3 that is adapted to the first slot along its circumference. The battery cover 2 is arranged on the mounting step 12 and is snapped into the first mounting groove 11 via the snap-fit strip 3 and the first slot.
[0030] Continue to refer to Figures 1 to 7As shown, in this embodiment, the first slot has two sets, and the inner wall of the first mounting slot 11 is provided with two snap-fit strips 3, each snap-fit strip 3 corresponding to a first slot. When installing the battery cover 2, the battery cover 2 is placed on the mounting step 12 of the first mounting slot 11, and then the battery cover 2 is rotated clockwise. The snap-fit strip 3 will be gradually inserted into the second connecting slot 22 through the first notch 23 and the first connecting slot 21 to achieve snap-fit. At the same time, when it is necessary to open the battery cover 2, the battery cover 2 can be rotated counterclockwise. At this time, during the rotation of the battery cover 2, the first inclined surface 24 will contact one end of the snap-fit strip 3, and the battery cover 2 can convert the rotational motion into a linear upward motion with the help of the inclined surface. At this time, the battery cover 2 is raised above the surface of the mounting housing 1, and then the battery cover 2 can be directly removed to replace the battery, which is convenient to use.
[0031] To make the first inclined surface 24 contact one end of the snap-fit strip 3 more smoothly, in this embodiment, one end of the snap-fit strip 3 is also provided with a second inclined surface 31 inclined towards the inner wall of the first mounting groove 11, and the bottom end of the snap-fit strip 3 near the second inclined surface 31 is also provided with an upwardly inclined third inclined surface 32.
[0032] In one embodiment, the bottom of the battery cover 2 is further provided with a ring-shaped limiting groove 25, and a waterproof ring 26 is embedded in the limiting groove 25. After the battery cover 2 is installed, the waterproof ring 26 will be pressed onto the mounting step 12 to improve the waterproof performance. At the same time, a ring-shaped pressing strip 27 extends downward from the bottom center of the limiting groove 25, and the cross-section of the pressing strip 27 is an inverted triangle. The use of a pointed pressing strip 27 can achieve a pointed corner press seal for waterproofing, unlike the traditional flat press seal, which results in a large interference fit of the waterproof ring 26 and the problem of the mounting housing 1 not closing tightly, thus further improving the sealing effect.
[0033] In one embodiment, the top of the battery cover 2 is further provided with a first groove 28. The first groove 28 has an arc-shaped structure, which facilitates the insertion of simple tools such as coins or keys, so as to rotate and open or lock the battery cover 2.
[0034] In addition, one embodiment provides a waterproof thermometer, including the aforementioned structure with an automatic lifting button battery door; a PCB board connected to the button battery is installed inside the mounting housing 1, and a display screen (for displaying temperature values and other information) connected to the PCB board is provided at the bottom of the mounting housing 1; a second mounting hole is provided at the top of the mounting housing 1, and a plastic shell 13 is provided inside the second mounting hole; a temperature sensor connected to the PCB board is installed inside the plastic shell 13, and the temperature sensor is placed in the plastic shell 13, so that its temperature conduction does not require a stainless steel tube medium (the temperature sensor of a conventional thermometer is mostly placed in...). (Conduction within a stainless steel tube is costly.) A lower-cost method allows direct temperature detection through the product's plastic wall, while also reducing the thickness of the plastic shell 13 to improve temperature response speed. In this embodiment, a limiting groove is provided on the top side of the housing 1, with a rotating shaft connected to each side of the groove's inner wall. The waterproof thermometer also includes a fixed bracket 14, one end of which is inserted into the limiting groove, and both sides of this end are rotatably connected to the limiting groove via a rotating shaft. The other end of the fixed bracket 14 has a hook 15 for hanging the thermometer outdoors, facilitating easy installation and disassembly.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
