[0029] like Figure 1 and Figure 2 As shown, a new type of pressure sensor suitable for the Internet of Things includes: a sensor body 1, a pipeline connector 11 fixed on the side of the sensor body 1, and an external pipeline 2 arranged at one end of the pipeline connector 11; a protective component is arranged on the side of the pipeline connector 11.

[0030] The protection component includes: a connecting ring 3 arranged on the side of the pipeline joint 11, two hinged plates 31 fixed on the side of the connecting ring 3, and a first connecting strip 32 and a second connecting strip 33 respectively hinged on the inner sides of the two hinged plates 31; a first semicircular piece 34 is fixed to the side of the first connecting strip 32, and a second semicircular piece 35 is fixed to the side of the second connecting strip 33; a plurality of first fixing blocks 36 are fixed to the side of the first semicircular piece 34 facing the second semicircular piece 35, and a plurality of second fixing blocks 37 are fixed to the side of the second semicircular piece 35 facing the first semicircular piece 34, and a snap-fit ​​component for connecting the first semicircular piece 34 and the second semicircular piece 35 is provided on the first fixing block 36 and the second fixing block 37.

[0031] It should be noted that the two hinged plates 31 and the first connecting strip 32 and the second connecting strip 33 are symmetrically arranged; the first semicircular piece 34 and the second semicircular piece 35 form a circle; after the external pipeline 2 is connected to the pipeline connector 11, the first connecting strip 32 and the second connecting strip 33, which are respectively located on the inner sides of the two hinged plates 31, are flipped upward from both sides of the connecting ring 3, so that the first semicircular piece 34 on one side of the first connecting strip 32 and the second semicircular piece 35 on one side of the second connecting strip 33 are synchronously flipped upward, and after flipping until the first semicircular piece 34 and the second semicircular piece 35 are in contact, the connection between the external pipeline 2 and the pipeline connector 11 can be enclosed, and through the cooperation of the snap-fit ​​assembly, the first semicircular piece 34 and the second semicircular piece 35 can be snap-fitted and connected, so that the connection can be protected to avoid damage to the connection, thereby improving the stability during use.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the locking assembly includes: a clamping strip 4 fixed on one side of the first fixed block 36, a clamping groove 41 opened on one side of the clamping strip 4, and a connecting groove 42 opened on the inner side of the second fixed block 37; a plurality of return springs 43 are fixed on the inner side of the connecting groove 42, a connecting piece 44 is fixed at one end of the plurality of return springs 43, and a positioning strip 45 is fixed on the inner side of the connecting piece 44.

[0033] It should be noted that the side surface of the card strip 4 close to one end is located inside the connecting groove 42, and the side surface of the positioning strip 45 close to one end is clamped on the inner side of the card slot 41; a plurality of return springs 43 are symmetrically arranged on the inner side of the connecting groove 42; when the first semicircular piece 34 and the second semicircular piece 35 are flipped upward and contacted, one end of the card strip 4 will gradually penetrate into the interior of the connecting groove 42, and at the same time pull the positioning strip 45 to move toward the outside of the second fixing block 37. During the movement, the positioning strip 45 will drive the connecting piece 44 fixed on the side to stretch a plurality of return springs 43. When the card strip 4 completes entering the interior of the connecting groove 42, , the pull on the positioning strip 45 is released, and the return springs 43 are reset to drive the connecting piece 44 and the positioning strip 45 to move toward the inside of the connecting groove 42, so that one end of the positioning strip 45 is clamped on the inner side of the clamping groove 41 on one side of the clamping strip 4, and the limiting fixation can be completed, thereby completing the clamping connection of the first semicircular piece 34 and the second semicircular piece 35. Similarly, when the first semicircular piece 34 and the second semicircular piece 35 need to be separated, it is only necessary to pull the positioning strip 45 to move toward the outside of the second fixing block 37, and the clamping strip 4 is separated from the inside of the connecting groove 42, and the separation of the first semicircular piece 34 and the second semicircular piece 35 can be completed.

[0034] One end of the positioning bar 45 located outside the second fixing block 37 is in a circular ring shape, so that the positioning bar 45 can be pulled to move by the end of the circular ring.

[0037] The inner sides of the first semicircular piece 34 and the second semicircular piece 35 are both threadedly connected with fastening bolts 5 , and a fastening ring 51 is provided at one end of the fastening bolt 5 facing the external pipe 2 .

[0038] It should be noted that the side of the fastening ring 51 is rotatably connected to one end of the fastening bolt 5; after the connection between the external pipeline 2 and the pipeline joint 11 is enclosed, the fastening bolts 5 located on the inner sides of the first semicircular piece 34 and the second semicircular piece 35 are rotated respectively, so that the fastening ring 51, to which one end of the fastening bolt 5 is rotatably connected, moves toward the side of the external pipeline 2. When the fastening ring 51 contacts the external pipeline 2, an extrusion force toward the middle can be applied to both sides of the external pipeline 2. Under the effect of extrusion and clamping, the stability of the external pipeline 2 connected to the pipeline joint 11 can be improved, thereby preventing the connection from being separated when being dragged, etc., thereby improving the reliability of the use process.

When the first semicircular piece 34 and the second semicircular piece 35 are flipped upward and contacted, one end of the clamping strip 4 will gradually penetrate into the interior of the connecting groove 42, and at the same time, the positioning strip 45 will be pulled to move toward the outside of the second fixing block 37. During the movement, the positioning strip 45 will drive the connecting piece 44 fixed on the side to stretch a plurality of return springs 43. When the clamping strip 4 completes entering the interior of the connecting groove 42, the pulling on the positioning strip 45 is released, and the plurality of return springs 43 are reset. The position drives the connecting piece 44 and the positioning strip 45 to move into the connecting groove 42, which will cause one end of the positioning strip 45 to be clamped on the inner side of the clamping groove 41 on one side of the clamping strip 4, so as to complete the limit fixation, thereby completing the clamping connection of the first semicircular piece 34 and the second semicircular piece 35, and the connection between the external pipeline 2 and the pipeline connector 11 can be enclosed, so as to protect the connection. After the connection between the external pipeline 2 and the pipeline connector 11 is enclosed, the fastening bolts 5 located on the inner sides of the first semicircular piece 34 and the second semicircular piece 35 are rotated respectively, so that the fastening ring 51 connected by one end of the fastening bolt 5 is rotated and moved toward the side of the external pipeline 2. When the fastening ring 51 contacts the external pipeline 2, an extrusion force toward the middle can be applied to both sides of the external pipeline 2. Under the effect of extrusion and clamping, the stability of the external pipeline 2 connected to the pipeline connector 11 can be improved.
