DETAILED DESCRIPTION

[0026] The following describes the multifunctional pressure detector provided by the present invention in detail with reference to the accompanying drawings and specific embodiments. It is also noted that, in order to provide a more detailed description of the embodiments, the following embodiments are best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternatives to implement them. Furthermore, the accompanying drawings are only for the purpose of describing the embodiments in more detail and are not intended to limit the present invention to any specific extent.

[0027] like Figure 1 - Figure 5 As shown, an embodiment of the present invention provides a multifunctional pressure detector, comprising: a front shell 1 and a rear shell 2, which are combined to form a rectangular box body with open ends for carrying detector components; a measuring device assembly 11, fixed inside the rectangular box body, and a high-precision negative pressure sensor 16 and a high-precision micro-pressure sensor 17 are provided inside the measuring device assembly 11, which are used for negative pressure detection and micro-pressure testing, respectively; a top shell 3, fixed at one end of the rectangular box body, and two first joints 5 are provided on the top shell 3, and the two first joints 5 are fixedly connected to the measuring device assembly 11, and the internal channels of the two first joints 5 are connected to the high-precision negative pressure sensor 16 and the high-precision micro-pressure sensor 17, respectively, and a magnetic joint is provided at one end of the first joint 5 away from the measuring device assembly 11; a measuring tube 7, with two ends respectively connected to the pipe to be tested and a second joint 6, and the end of the second joint 6 is also provided with a magnetic joint, and the second joint 6 is sealed with the first joint 5; a bottom shell 4, fixed at one end of the rectangular box body away from the top shell 3, and a charging interface 9 is provided on the bottom shell 4.

[0028] By integrating the high-precision negative pressure sensor 16 and the high-precision micro-pressure sensor 17 into the measuring device assembly 11, it is possible to simultaneously measure pressure values ​​in different ranges on the same device, which not only reduces the number of devices but also improves the convenience and efficiency of on-site operations. In addition, the magnetic sealing connection through the magnetic joint realizes quick connection, and two pressure tests can be performed at the same time, further improving the applicability and detection efficiency of the detector.

[0029] like Figure 4 As shown, a first through groove 14 and a second through groove 15 are provided inside the measuring device assembly 11. The first through groove 14 and the second through groove 15 are independent of each other and are respectively connected to a high-precision negative pressure sensor 16 and a high-precision micro-pressure sensor 17. The first through groove 14 and the second through groove 15 are respectively connected to the two first joints 5.

[0030] Among them, sealing gaskets are provided at the interface positions of the first through groove 14 and the second through groove 15 and the two sensors, so as to improve the sealing performance of the connection between the two and ensure the measurement accuracy.

[0031] like Figure 5As shown, the first connector 5 includes: a fixing seat 51, which is used to be sealed and connected to one end of the first through groove 14 or the second through groove 15 away from the high-precision negative pressure sensor 16 or the high-precision micro-pressure sensor 17, and a channel connecting the two ends is provided inside the fixing seat 51; a first connecting member 52, which is fixedly connected to the fixing seat 51, and a magnetic connector is provided inside the first connecting member 52.

[0032] The fixing seat 51 is a bolt structure, and is connected to the measuring device assembly 11 through threads, thereby achieving a sealed connection between the fixing seat 51 and the first through groove 14 or the second through groove 15 .

[0033] like Figure 1 As shown, the second joint 6 includes a second connecting member 61 fixedly connected to the measuring tube 7. The second connecting member 61 and the first connecting member 52 are both circular tube structures, and the inner diameter of the second connecting member 61 is the same as the outer diameter of the first connecting member 52. The second connecting member 61 and the first connecting member 52 are connected in a socket manner.

[0034] The magnetic joint is protected by providing the first connecting member 52 and the second connecting member 61 , and when the first joint 5 is connected to the second joint 6 , the connection stability of the two joints is further improved through the socket connection between the two joints.

[0035] Furthermore, thread grooves are provided on the outer wall of the first connecting member 52 and the inner wall of the second connecting member 61, and the two are threadedly connected to each other. With the cooperation of the sealing gasket, a secondary sealing connection is achieved at the connection points of the two joints, further improving the sealing performance of the joints.

[0036] like Figure 4 and Figure 5 As shown, the magnetic component includes: an elastic rubber sleeve 53, which has a circular tubular structure and one end is sealed with the inner wall of the measuring tube 7 or the fixing seat 51, and a cylindrical cavity is provided inside the side wall of the elastic rubber sleeve 53; a top block 54, which has an annular structure, is arranged inside the side wall of the elastic rubber sleeve 53 and is located near one end of the fixing seat 51 or the measuring tube 7; a magnetic ring 56, which has an annular structure, is arranged inside the side wall of the elastic rubber sleeve 53 and is arranged relatively parallel to the top block 54, and the edges of the end of the magnetic ring 56 that contacts the elastic rubber sleeve 53 are rounded to prevent sharp edges from scratching the side wall of the elastic rubber sleeve 53 and affecting the airtight performance; a spring 55, which is arranged inside the side wall of the elastic rubber sleeve 53, and its two ends are respectively in contact with the top block 54 and the magnetic ring 56, for supporting the side wall of the elastic rubber sleeve 53.

[0037] The elastic rubber sleeve 53, top block 54, magnetic ring 56 and spring 55 in the magnetic assembly together form an elastic adaptive sealing structure. When the second joint 6 is docked with the first joint 5, the elastic rubber sleeve 53 is close to each other under the support of the spring 55, and is tightly attached to each other under the magnetic attraction of the two magnetic rings 56 to ensure the sealing effect.

[0038] Furthermore, in the first connector 5, the magnetic ring 56 inside the magnetic connector for connecting the first through slot 14 and the second through slot 15 has its magnetic pole facing the outside oppositely, and the magnetic ring 56 in the corresponding second connector 6 is set in reverse, so that when connecting the measuring tube 7, the accuracy of the connector connection is distinguished by the mutual magnetic attraction or repulsion of the two connectors.

[0039] like Figure 2 As shown, it also includes a built-in power supply 12, which is arranged inside the rectangular box body and is used to provide power. The built-in power supply 12 is electrically connected to the charging interface 9 for replenishing electric energy to the built-in power supply 12.

[0040] like Figure 2 As shown, it also includes a main control circuit board 13, which is arranged inside the rectangular box body and is electrically connected to the high-precision negative pressure sensor 16, the high-precision micro-pressure sensor 17, and the built-in power supply 12, and is used to read the pressure parameters of the high-precision negative pressure sensor 16 and the high-precision micro-pressure sensor 17 and perform data analysis; it also includes a button assembly 10, which is arranged on the side wall of the rectangular box body and is electrically connected to the main control circuit board 13, and is used to control the power on and off and mode change of the detector; it also includes a display screen 8, which is arranged on the front shell 1, and is electrically connected to the main control circuit board 13 and the built-in power supply 12, and is used to display the value analyzed by the main control circuit board 13.

[0041] The intelligent control system of this utility model is comprised of a built-in main control circuit board 13, display screen 8, and button assembly 10. The main control circuit board 13 reads high-precision sensor data and performs real-time analysis and processing. The display screen 8 displays this processed data in intuitive numerical or graphical form, allowing the user to quickly understand the current pressure status. The button assembly 10 provides convenient operation functions such as power on / off and mode change. This intelligent design makes the pressure detector more user-friendly and simplifies calibration, making it easy for even non-professionals to use.

[0042] The technical solution provided by the present invention is that when performing a pressure test, the power button in the button assembly 10 is pressed to start the detector. At this time, the display screen 8 will light up, showing the initial interface or the state to be detected; as needed, the working mode of the detector is set through the button assembly 10, such as selecting the negative pressure detection mode, the micro-pressure detection mode or the simultaneous detection mode; then one end of the measuring tube 7 is connected to the pipeline to be tested to ensure that the connection is tight and there is no leakage; through the socket connection of the first connector 52 and the second connector 61, and in conjunction with the magnetic attraction of the magnetic connector, a quick and stable connection is achieved. Note that if you hear a slight "click" sound or feel obvious magnetic adsorption, it usually means that the connection is complete. If the two connectors are mutually exclusive, it means that the connector contact is wrong, and the second connector 6 needs to be replaced with another first connector 5 for connection.

[0043] Once the measuring tube 7 is connected, the high-precision negative pressure sensor 16 and the high-precision low-pressure sensor 17 automatically detect the pressure in the pipe under test. The main control circuit board 13 reads the sensor data in real time and performs data analysis and processing. The processed results are displayed on the display screen 8, allowing the user to directly read the current pressure value or chart information.

[0044] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
