DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-6 The utility model provides the following technical solutions: a non-invasive pressure sensor adapted to hoses of different sizes, comprising a lower mounting ring 1, wherein positioning bolts 2 are symmetrically arranged inside the lower mounting ring 1, an upper mounting ring 3 is arranged at the upper end of the lower mounting ring 1, a hose groove 4 is arranged inside the upper mounting ring 3, notches 9 are symmetrically arranged at both ends of the hose groove 4, a hose to be tested 10 is arranged inside the hose groove 4, a hose placement component 5 is arranged on the inner wall surface of the hose groove 4, a sensor mounting groove 6 is arranged at the middle upper end of the hose groove 4, a positioning mounting component 7 is arranged on one side of the sensor mounting groove 6, and a non-invasive pressure sensor body 8 is arranged inside the sensor mounting groove 6.

[0024] Specifically, the hose placement assembly 5 includes an abutment protection assembly 51, a clamping plate 52, a limit spring 53, a damping telescopic rod 56 and a limit device 57, wherein a damping telescopic rod 56 is symmetrically arranged on one side of the hose groove 4, a limit spring 53 is sleeved on the surface of the damping telescopic rod 56, a clamping plate 52 is arranged at one end of the damping telescopic rod 56, an abutment protection assembly 51 is arranged on the other side of the hose groove 4, and a limit device 57 is arranged on one side of the bottom end of the hose groove 4.

[0025] By adopting the above technical solution, the hose 10 to be tested needs to be installed before the non-invasive pressure sensor body 8 is installed, and the handle 55 is pulled to drive the clamping plate 52 to move. At the same time, the damping telescopic rod 56 contracts and the limit spring 53 is compressed. Then, the hose 10 to be tested is inserted into the notch 9 at one end of the hose groove 4 for placement, and passed out from the notch 9 at the other end. Then, the handle 55 is released to reset the limit spring 53. At the same time, the clamping plate 52 slowly resets and moves toward the hose 10 to be tested and fits with it. Then, the bolt is passed through the threaded hole inside the handle 55 to fix it, so as to prevent the limit spring 53 from moving again and ensure the stability of the placement of hoses 10 to be tested with different calibers.

[0026] Specifically, a handle 55 is provided in the middle of the upper end of the pressing plate 52 , a locking block 54 is provided on one side of the pressing plate 52 , and a movable shaft is provided at the bottom end of the locking block 54 .

[0027] By adopting the above technical solution, it is ensured that the locking block 54 can be rotated for use, thereby improving its corresponding accuracy and convenience.

[0028] Specifically, the abutment protection component 51 includes a lock-shaped hole 511, a protection plate 512, an airbag 513 and a damping shaft 514, wherein the damping shaft 514 is arranged inside the upper mounting ring 3, the protection plate 512 is arranged on the surface of the damping shaft 514, the airbag 513 is arranged on the surface of the protection plate 512, and the lock-shaped hole 511 is arranged inside the protection plate 512.

[0029] By adopting the above technical scheme, the protective plate 512 is rotated along the damping shaft 514 to cover the upper end of the hose groove 4, and the locking block 54 is rotated along the movable axis to make it correspond to the hole type of the locking hole 511. When the protective plate 512 is attached to the surface of the upper mounting ring 3, the locking block 54 passes through the inside of the locking hole 511, and then the locking block 54 is rotated again to make it misaligned with the locking hole 511, thereby ensuring the stability of the installation of the protective plate 512, and the airbag 513 at the bottom end of the protective plate 512 abuts against the surface of the hose 10 to be tested and fits it to limit it, preventing the hose 10 to be tested from shaking during use, improving the installation strength of the hose 10 to be tested, and ensuring the stability of the equipment. At the same time, the airbag 513 is attached to one side of the clamping plate 52, ensuring that the airbag 513 and the clamping plate 52 act simultaneously to limit the hose 10 to be tested, ensuring its natural state after installation, and preventing inaccurate detection due to excessive external pressure.

[0030] Specifically, the limiting device 57 includes a limiting baffle 571, a spherical stopper 572 and a positioning spring 573, wherein a positioning spring 573 is arranged inside the upper mounting ring 3, a limiting baffle 571 is arranged at one end of the positioning spring 573, and a spherical stopper 572 is arranged on the surface of the limiting baffle 571.

[0031] By adopting the above technical solution, when the hose 10 to be tested is placed, its two ends close to the slot 9 abut against one side of the spherical stopper 572, so that the positioning spring 573 at one end of the limit baffle 571 is compressed. When the hose 10 to be tested is placed stably, the positioning spring 573 pushes the spherical stopper 572 to reset and limit the upper end of the hose 10 to prevent the hose 10 to be tested from escaping from the inside of the hose groove 4.

[0032] When this embodiment is used: before the non-invasive pressure sensor body 8 is installed, the hose 10 to be tested needs to be installed, the handle 55 is pulled to drive the clamping plate 52 to move, and at the same time, the damping telescopic rod 56 is contracted and the limit spring 53 is compressed, and then the hose 10 to be tested is inserted into the notch 9 at one end of the hose groove 4 for placement, and passes through the notch 9 at the other end, and then the handle 55 is released to reset the limit spring 53, and at the same time, the clamping plate 52 slowly resets and moves toward the hose 10 to be tested and fits with it, and then the bolt is passed through the threaded hole inside the handle 55 to fix it, so as to prevent the limit spring 53 from moving again, and ensure the stability of the placement of hoses 10 to be tested with different calibers;

[0033] When the hose 10 to be tested is placed, the positions of both ends thereof near the notch 9 abut against one side of the ball stopper 572, so that the positioning spring 573 at one end of the limit baffle 571 is compressed. When the hose 10 to be tested is placed stably, the positioning spring 573 pushes the ball stopper 572 to return to the upper end of the hose 10 to limit the position, thereby preventing the hose 10 to be tested from being separated from the inside of the hose groove 4.

[0034] Finally, the protective plate 512 is rotated along the damping shaft 514 to cover the upper end of the hose groove 4, and the locking block 54 is rotated along the movable axis to make it correspond to the hole type of the locking hole 511. When the protective plate 512 is fitted on the surface of the upper mounting ring 3, the locking block 54 passes through the inside of the locking hole 511, and then the locking block 54 is rotated again to make it misaligned with the locking hole 511, ensuring the stability of the installation of the protective plate 512, and the airbag 513 at the bottom end of the protective plate 512 abuts against the surface of the hose 10 to be tested and fits it to limit it, preventing the hose 10 to be tested from shaking during use, improving the installation strength of the hose 10 to be tested, and ensuring the stability of the equipment. At the same time, the airbag 513 is fitted on one side of the clamping plate 52, ensuring that the airbag 513 and the clamping plate 52 act simultaneously to limit the hose 10 with a test, ensuring its natural state after installation, and preventing inaccurate detection due to excessive external pressure.

[0035] Example 2

[0036] The difference between this embodiment and embodiment 1 is that: specifically, the positioning and installation assembly 7 includes a clamping block 71, a torsion spring 72, a clamping spring 73 and a movable pressure plate 74, wherein a movable pressure plate 74 is provided on one side of the sensor installation slot 6, a torsion spring 72 is provided on the upper end of the movable pressure plate 74, a clamping block 71 is provided on the upper end of the torsion spring 72, and a clamping spring 73 is provided on one side of the movable pressure plate 74.

[0037] When this embodiment is in use: when installing the non-invasive pressure sensor body 8, pull the movable pressure plate 74 to compress the compression spring 73, and at the same time rotate the compression block 71 along the torsion spring 72 to place the non-invasive pressure sensor body 8 inside the sensor mounting groove 6 and install it close to one side of the hose 10 to be tested, and then release the movable pressure plate 74 and the compression block 71. At this time, the compression spring 73 is reset so that the movable pressure plate 74 abuts against one side of the non-invasive pressure sensor body 8 so that it is stably installed inside the sensor mounting groove 6. At the same time, the torsion spring 72 drives the compression block 71 to reset so that the compression block 71 abuts against the upper end of the non-invasive pressure sensor body 8 to prevent the non-invasive pressure sensor body 8 from loosening, ensure that the side and bottom surfaces of the non-invasive pressure sensor body 8 are closely fitted with the hose 10 to be tested, improve the stability of equipment installation and use, ensure the use effect of the equipment, and improve the detection accuracy.

[0038] Working principle and use process of the utility model: When the utility model is used, the hose 10 to be tested needs to be installed before the non-invasive pressure sensor body 8 is installed, the handle 55 is pulled to drive the clamping plate 52 to move, and at the same time, the damping telescopic rod 56 is contracted and the limit spring 53 is compressed, and then the hose 10 to be tested is inserted into the notch 9 at one end of the hose groove 4 for placement, and passes through the notch 9 at the other end, and then the handle 55 is released to reset the limit spring 53, and at the same time, the clamping plate 52 slowly resets and moves toward the hose 10 to be tested and fits with it, and then the bolt is passed through the threaded hole inside the handle 55 to fix it, so as to prevent the limit spring 53 from moving again, and ensure the stability of the placement of hoses 10 to be tested with different calibers;

[0039] When the hose 10 to be tested is placed, the positions of both ends thereof near the notch 9 abut against one side of the ball stopper 572, so that the positioning spring 573 at one end of the limit baffle 571 is compressed. When the hose 10 to be tested is placed stably, the positioning spring 573 pushes the ball stopper 572 to return to the upper end of the hose 10 to limit the position, thereby preventing the hose 10 to be tested from being separated from the inside of the hose groove 4.

[0040] Finally, the protective plate 512 is rotated along the damping rotating shaft 514 to cover the upper end of the hose groove 4, and the locking block 54 is rotated along the movable axis to make it correspond to the hole type of the locking hole 511. When the protective plate 512 is attached to the surface of the upper mounting ring 3, the locking block 54 passes through the inside of the locking hole 511, and then the locking block 54 is rotated again to make it misaligned with the locking hole 511, ensuring the stability of the installation of the protective plate 512, and the air bag 513 at the bottom end of the protective plate 512 abuts against the surface of the hose 10 to be tested and fits it to limit it, preventing the hose 10 to be tested from shaking during use, improving the installation strength of the hose 10 to be tested, and ensuring the stability of the equipment. At the same time, the air bag 513 is attached to one side of the clamping plate 52, ensuring that the air bag 513 and the clamping plate 52 act at the same time to limit the hose 10 with the test, ensuring its natural state after installation, and preventing inaccurate detection caused by excessive external pressure;

[0041] Then the non-invasive pressure sensor body 8 is installed, the movable pressure plate 74 is pulled to compress the compression spring 73, and the compression block 71 is rotated along the torsion spring 72 to place the non-invasive pressure sensor body 8 inside the sensor mounting groove 6 and install it close to one side of the hose 10 to be tested, and then the movable pressure plate 74 and the compression block 71 are released. At this time, the compression spring 73 is reset so that the movable pressure plate 74 abuts against one side of the non-invasive pressure sensor body 8 so that it is stably installed inside the sensor mounting groove 6. At the same time, the torsion spring 72 drives the compression block 71 to reset so that the compression block 71 abuts against the upper end of the non-invasive pressure sensor body 8 to prevent the non-invasive pressure sensor body 8 from loosening, ensure that the side and bottom surfaces of the non-invasive pressure sensor body 8 are in close contact with the hose 10 to be tested, improve the stability of equipment installation and use, ensure the use effect of the equipment, and improve the detection accuracy.
