Technical Field
[0001] This utility model relates to the field of pressure transmitter technology, specifically an automotive air conditioning pressure transmitter. Background Technology
[0002] A pressure transmitter is a pressure sensor that outputs a standard signal. It is an instrument that accepts pressure variables and converts them proportionally into a standard output signal. It transforms the physical pressure parameters of gases, liquids, etc., sensed by the pressure-sensing element sensor into a standard electrical signal, which is then supplied to secondary instruments such as indicators, alarms, recorders, and controllers for measurement, indication, and process regulation. Pressure transmitters are one of the most commonly used sensors in industrial practice, and they are widely used in various industrial automation environments.
[0003] Current pressure transmitters are all installed on measuring pipelines. However, the traditional method involves connecting the pressure transmitter to the pipeline itself using a connection structure. Due to the complex outdoor environment, this installation method, while simple, is not stable enough and may damage the pressure transmitter. Therefore, an automotive air conditioning pressure transmitter is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automotive air conditioning pressure transmitter. This transmitter offers advantages such as reduced risk of damage during measurement and better performance. It solves the problem that traditional installation methods, which connect the pressure transmitter to the measured pipeline via its own connection structure, are not stable enough due to the complex outdoor environment and may damage the pressure transmitter.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive air conditioning pressure transmitter, including an air conditioning pipe, a transmitter body installed on the outer surface of the air conditioning pipe, an instrument fixedly connected to the front of the transmitter body, and a detection and protection component provided on the outer surface of the air conditioning pipe.
[0006] The detection and protection assembly includes two mounting plates, both located on the outer surface of the air conditioning duct. A fixing block is fixedly connected to the surface of the left mounting plate, and a telescopic rod is elastically connected inside the fixing block. A support block is fixedly connected to the outer surface of the right mounting plate, and a lever is hinged to the top of the support block. A sleeve is fixedly connected to the surface of the right mounting plate, and an adjusting rod is elastically connected inside the sleeve. Limit covers are fixedly connected to the opposite sides of the telescopic rod and the adjusting rod.
[0007] Furthermore, the two mounting plates are internally threaded with studs, and both mounting plates are pressed onto the outer surface of the air conditioning duct by studs. Each of the two mounting plates is fixedly connected to a limiting plate on its opposite side, and both limiting plates are attached to the outer surface of the transmitter body.
[0008] The effect of adopting the above technical solution is that when inspecting air conditioning ducts, the transmitter body can be installed on the outer surface of the air conditioning duct via studs, which facilitates subsequent inspection and maintenance.
[0009] Furthermore, the fixed block has a movable groove inside, through which the telescopic rod moves within the fixed block.
[0010] The effect of adopting the above technical solution is that the movable groove can play a guiding role during the sliding process of the telescopic rod, ensuring that the range of motion is limited and improving stability.
[0011] Furthermore, the actuating lever is movably connected to the adjusting lever, and a handle is fixedly connected to the top of the actuating lever.
[0012] The effect of adopting the above technical solution is that the outer surface of the handle can increase the friction during the toggle lever operation, thus minimizing slippage when using manual operation.
[0013] Furthermore, the sleeve has a movable hole inside, and the adjusting rod is slidably connected to the sleeve through the movable hole.
[0014] The effect of adopting the above technical solution is that the adjusting rod slides inside the sleeve through the movable hole, which can ensure that the transmitter body is more convenient and stable when it is limited, and is less prone to shaking.
[0015] Furthermore, both of the limiting covers have rubber pads fixedly connected inside, and both rubber pads are arc-shaped.
[0016] The effect of adopting the above technical solution is that the rubber pad can play a filling role, reduce the existence of protective gaps, and further improve the limiting effect.
[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0018] 1. This automotive air conditioning pressure transmitter, when the air conditioning duct is being tested, after the transmitter body is installed on top of the air conditioning duct, two mounting plates are fixed to the outer surface of the air conditioning duct. This makes the left limit cover located on the left side of the instrument when the telescopic rod is in place, while the right limit cover protects it when the lever is activated. Finally, the two limit covers protect the front of the transmitter body and the instrument, ensuring that it is not easily affected by external interference during testing, thereby improving the protection of the device.
[0019] 2. This automotive air conditioning pressure transmitter, by setting rubber pads inside the two limit covers, makes the instrument less susceptible to external interference during the testing process, thereby improving the protection effect of the device. The presence of the two limit plates ensures that the transmitter body is not prone to displacement during use, thus improving the detection accuracy of the air conditioning duct.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-3 This embodiment of an automotive air conditioning pressure transmitter includes an air conditioning duct 1, a transmitter body 2 mounted on the outer surface of the air conditioning duct 1, an instrument 3 fixedly connected to the front of the transmitter body 2, and a detection and protection assembly provided on the outer surface of the air conditioning duct 1. The detection and protection assembly includes two mounting plates 4, both of which are located on the outer surface of the air conditioning duct 1. The two mounting plates 4 are internally threaded with studs, and both mounting plates 4 are pressed onto the outer surface of the air conditioning duct 1 by studs. The purpose is that when the air conditioning duct 1 is being tested, the transmitter body 2 can be mounted on the outer surface of the air conditioning duct 1 by studs, which facilitates subsequent testing and maintenance.
[0026] A fixing block 5 is fixedly connected to the surface of the left mounting plate 4. A telescopic rod 6 is elastically connected inside the fixing block 5. A movable groove is opened inside the fixing block 5. The telescopic rod 6 moves inside the fixing block 5 through the movable groove. The purpose is that the movable groove can guide the telescopic rod 6 during the sliding process, ensuring that the range of movement is limited and improving stability.
[0027] A support block 7 is fixedly connected to the outer surface of the right mounting plate 4. A lever 8 is hinged to the top of the support block 7. A sleeve 9 is fixedly connected to the surface of the right mounting plate 4. An adjusting rod 10 is elastically connected inside the sleeve 9. A movable hole is opened inside the sleeve 9. The adjusting rod 10 is slidably connected to the sleeve 9 through the movable hole. The adjusting rod 10 slides inside the sleeve 9 through the movable hole, which can ensure that it is more convenient and stable when limiting the transmitter body 2 and is less prone to shaking.
[0028] The lever 8 is movably connected to the adjusting rod 10. A handle is fixedly connected to the top of the lever 8. During the tossing process, the outer surface of the handle can increase the friction to ensure that slippage is avoided as much as possible when manually moving the lever 8.
[0029] Limiting covers 11 are fixedly connected to the opposite sides of the telescopic rod 6 and the adjusting rod 10. Rubber pads 12 are fixedly connected inside the two limiting covers 11. The two rubber pads 12 are arc-shaped. Limiting plates 13 are fixedly connected to the opposite sides of the two mounting plates 4. The two limiting plates 13 are attached to the outer surface of the transmitter body 2. The purpose is that the rubber pads can play a filling role, reduce the existence of protective gaps, and further improve the limiting effect.
[0030] In this embodiment, by setting rubber pads 12 inside the two limiting covers 11, the instrument 3 is less susceptible to external interference during the detection process, thereby improving the protection effect of the device. The presence of the two limiting plates 13 ensures that the transmitter body 2 is less likely to deviate during use, thereby improving the detection accuracy of the air conditioning duct.
[0031] The working principle of the above embodiments is as follows:
[0032] When the air conditioning duct is being tested, the transmitter body 2 is installed on top of the air conditioning duct 1, and two mounting plates 4 are fixed to the outer surface of the air conditioning duct 1. This allows the left limiting cover 11 to be positioned to the left of the instrument 3 when the telescopic rod 6 is in place, while the right limiting cover 11 protects it when the lever 10 is activated. Finally, the two limiting covers 11 protect the front of the transmitter body 2 and the instrument 3, ensuring that it is not easily affected by external interference during testing, thereby improving the protection of the device.
