Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor for measuring air temperature and humidity. Background Art

[0002] The temperature and humidity sensor is a device that can detect temperature and humidity information. It is a clever combination of a temperature sensor and a temperature sensor. The basic principle of the temperature sensor is to convert the temperature value of the environment into the change of the electrical quantity of the sensitive unit, and finally convert the formula by reading the voltage value of the sensitive unit to obtain the temperature value. Common electrical quantities include: voltage, current, resistance, capacitance, etc. The basic principle of the humidity sensor is to convert humidity into the type of electrical signal to be processed. According to the type of electrical signal to be processed by the humidity sensor, it can be divided into: capacitive type, resistive type, piezoelectric, triboelectric type, etc.

[0003] Existing temperature and humidity sensors are usually installed by using multiple screws and installation sites. However, if there are no screw holes at the installation site, it is necessary to drill holes on site, which not only reduces the installation efficiency but also causes irreversible damage to the installation site.

[0004] Although a certain existing temperature and humidity sensor can be installed on a mounting surface by clamping or relative alignment, it cannot be installed on a cylindrical surface. In this case, an additional connecting clamp is required for installation, which limits the scope of application. Utility Model Content

[0005] The utility model aims to provide a sensor for measuring air temperature and humidity to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a sensor for measuring air temperature and humidity, comprising a mounting base; positioning rods are slidably connected to both sides of the mounting base, a connecting rod is movably connected to one side of the positioning rod, and a driving disk is movably connected to one end of the connecting rod away from the positioning rod, and a gear part is connected to the bottom of the driving disk through a connecting rod, and the gear part and the driving disk are both movably connected to the inside of the mounting base; an adapter seat is movably connected to one end of the positioning rod, and the adapter seat is movably connected to the inside of the adapter seat, and the adapter rod is provided with connecting shafts at the upper and lower ends of the adapter rod, the connecting shaft is welded to one end of the adapter rod, a ratchet is welded around the periphery of the connecting shaft, and a block is clamped on one side of the ratchet; the positioning rod is used to expand or contract outward to match the adapter seat for installation; the adapter seat is used to allow the adapter rod to rotate and to clamp objects.

[0007] Preferably, a spiral worm gear is movably connected to one side of the mounting base, and one end of the spiral worm gear is meshingly connected to one side of the gear member to allow the two positioning rods to move away from or closer to each other for clamping, and the positioning rods are provided with a receiving groove for receiving the adapter rod.

[0008] Preferably, a connection block is welded on one side of the positioning rod, the connection block is movably connected to the connection rod, a docking block is welded on one side of the positioning rod, and a linkage block is welded on one side of the adapter seat.

[0009] Preferably, a linkage shaft is welded on one side of the linkage block, and the linkage shaft is movably connected to the inside of the docking block. A positioning pin is provided on the periphery of the linkage block, and the positioning pin connects the linkage block and the docking block to locate the position of the adapter seat and the positioning rod.

[0010] Preferably, the adapter rod is movably connected to the adapter seat via a connecting shaft, and rubber blocks are arranged and distributed on one side of the adapter rod, and the rubber blocks are bonded to the adapter rod.

[0012] Preferably, a sensor body is connected above the mounting base via bolts.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, the utility model provides a mounting base and an adapter seat and their respective objects. After the sensor body is installed on the top of the mounting base by bolts, it is placed at the mounting position and rotated by connecting the spiral worm gear with an external tool such as a wrench, thereby rotating the gear member and the drive disk member. During the rotation, the positioning rod is retracted toward the inside of the mounting base through the connecting rod. During the retraction process, it is clamped by the unfolded adapter rod, or rotated in the opposite direction by expanding the adapter rod so that one end of the adapter rod contacts the mounting wall, so that the entire object is installed between the two objects. Finally, not only does it not need to punch holes on the mounting surface, which improves the installation efficiency, but the installation will also be faster and more convenient.

[0015] Secondly, the utility model provides an installation base, an adapter seat and their respective objects. When it is necessary to install them on the periphery of the cylinder, the adapter rod can be manually moved to rotate around the connecting shaft. During the rotation, the ratchet will continuously engage with the clamping block until it stops. The clamping block will cooperate with the spring member to position the ratchet. At this time, the positioning pin can be pulled out so that the adapter seat can rotate around the linkage shaft, so that the adapter rod can contact the surface of the cylinder. At this time, selecting the spiral worm gear will allow the two positioning rods to clamp the adapter seat and its objects, so that it can finally be installed on the periphery of the cylindrical mounting surface, expanding its scope of application.
