Description

TECHNICAL FIELD

[0002] Instrument is used to detect, measure, observe, calculate various physical quantities, material composition, material property parameters and the appliance or equipment of other. Instrument can be divided into according to function: detection instrument, measurement instrument, observation instrument and so on.

[0003] Among them, detection instrument is mainly used to detect physical quantity, chemical quantity and other parameters. For example, temperature and humidity sensor can detect environmental temperature and humidity, and pressure gauge can measure the pressure of gas or liquid. These instruments and meters perceive physical or chemical changes through sensitive components, and convert them into readable signals, such as electrical signals, mechanical signals, etc.

[0004] The working principle of existing temperature and humidity sensor is mostly based on the response of physical or chemical properties to temperature and humidity. Capacitive humidity sensor measures humidity by using the change of the capacitance value of humidity-sensitive material with humidity. If humidity is too high, water vapor may condense on the surface of the sensor's sensing element, changing its physical properties and causing the measured capacitance value to deviate, thereby reducing the accuracy of humidity measurement. And many temperature and humidity sensors contain electronic components, such as circuit boards, chips, etc. These electronic components are usually sensitive to humidity. Excessive humidity may cause electronic components to short circuit, corrode, and long-term exposure to a humid environment may cause component aging and damage.

[0026] Iron sheet 21 is bonded at the top end and bottom of back plate 2, slot body is opened on the front of mounting plate 3, magnet 33 is embedded and installed at the top and bottom of the slot body of mounting plate 3, support rod 7 is rotatably installed at the bottom center position of mounting plate 3, support rod 7 is U-shaped structure, the front end of support rod 7 is located at the bottom of baffle 5.

[0027] Furthermore, in the above technical solution, pads 32 are fixedly installed at the four corners of the back of the mounting plate 3. The back of the mounting plate 3 has a hollow structure. The back of the back plate 2 is inserted into the groove on the front of the mounting plate 3. The groove on the front of the mounting plate 3 is used to accommodate the back plate. The magnets 33 embedded at the top and bottom of the groove cooperate with the iron sheet of the back plate 2, making the installation process simple, quick and stable.

[0028] Furthermore, in the above technical solution, connecting parts 23 are fixedly installed on both the upper and lower ends of the back plate 2. The two sides of the instrument housing 1 are threadedly connected to the connecting parts 23 on both sides of the back plate 2 by bolts. The inner ring of the rubber sleeve 4 wraps around the connection between the instrument housing 1 and the back plate 2, and the outer ring of the rubber sleeve 4 fits against the edge of the mounting plate 3. The connection between the back plate 2 and the instrument housing 1 ensures the stability and integrity of the entire structure. The iron sheets bonded to the top and bottom interact with the magnets in the mounting plate groove, realizing convenient fixing and disassembly between the back plate 2 and the mounting plate 3, which facilitates the installation and maintenance of instruments.

[0029] Furthermore, in the above technical solution, protrusions 41 are fixedly installed at the four corners of the outer ring of the rubber sleeve 4, and slots 31 are opened at the four corners of the front side of the mounting plate 3. The positions of the protrusions 41 and the slots 31 correspond to each other, and the protrusions 41 and the slots 31 are engaged and connected.

[0030] Furthermore, in the above technical solution, a slot 11 is provided on the back of the instrument housing 1, near the edge, and an adhesive strip 22 is fixedly installed on the front of the back plate 2.

[0031] Furthermore, in the above technical solution, a heat dissipation hole 12 is provided at the bottom front end of the instrument housing 1. This heat dissipation hole 12 provides a channel for internal heat dissipation, ensuring the instrument operates within its normal operating temperature range and preventing component performance degradation or malfunction due to overheating. When heat dissipation is required, it allows for effective heat removal. The upper surface of the front end of the baffle 5 covers the outside of the heat dissipation hole 12 at the bottom of the instrument housing 1. The rotation angle of the baffle 5 is 0-90°. The rotation angle of the baffle 5 from 0 to 90 degrees allows for flexible control of the opening and closing state of the heat dissipation hole 12. In a humid environment, the baffle 5 can rotate to cover the heat dissipation hole 12, forming a barrier to prevent moisture from entering the instrument through the heat dissipation hole, ensuring a moisture-proof effect. When the environment is dry and the instrument needs heat dissipation, the baffle 5 can rotate open, allowing the heat dissipation hole 12 to function normally and ensuring timely heat dissipation.

[0032] The working process of the moisture-proof instrument provided by this utility model is as follows:

[0033] The convex block 6 is the rotating connection point of the baffle 5, which enables the baffle 5 to stably rotate at the lower end of the mounting plate 3, and realizes the control of the opening and closing of the heat dissipation hole 12. When the baffle 5 rotates to the open position, the supporting rod 7 can support the baffle 5, so that it can maintain a stable open state and will not swing or close at will due to gravity or other external forces, ensuring the stability and reliability of the heat dissipation process, and also avoiding damage to the surrounding parts or affecting the normal operation of the instrument due to the shaking of the baffle 5.

[0034] The back of the mounting plate 3 is provided with a cushion block 32, which can form a certain gap between the mounting plate 3 and the mounting surface when the instrument is installed on the wall or other plane, so as to avoid water vapor penetrating into the instrument through the mounting surface due to direct contact, and also facilitate the circulation of air on the back of the mounting plate, which plays a certain auxiliary role in heat dissipation. The heat dissipation hole 12 at the bottom of the instrument shell can ensure the dissipation of heat inside the instrument under normal circumstances, preventing damage to electronic components due to heat accumulation. The design of the baffle 5 is very ingenious, which can be rotated to cover the heat dissipation hole when in a humid environment or when heat dissipation is not needed, preventing water vapor from entering the instrument from the heat dissipation hole; when the instrument is in a dry environment and needs to dissipate heat, the baffle can be rotated to open, without affecting the heat dissipation effect, realizing the flexible switching of the moisture-proof and heat dissipation functions, and improving the adaptability and reliability of the instrument in different environmental conditions.

[0035] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
