Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pressure detector for the internal air pressure of a pressure vessel, including an installation pipe 1 and an air pressure detection gauge 7. A regulating pipe 3 is slidably assembled on the top of the installation pipe 1. An angle adjusting assembly is installed between the regulating pipe 3 and the air pressure detection gauge 7, and a height adjusting assembly is installed between the regulating pipe 3 and the installation pipe 1;

[0024] The height adjusting assembly includes an adjusting sleeve 2. An installation cavity is provided on the outer surface of the top of the installation pipe 1. A sliding ring 18 is integrally connected to the adjusting sleeve 2. The sliding ring 18 is slidably connected to the inner wall of the installation cavity on the installation pipe 1. A first spring 12 is assembled between the sliding ring 18 and the installation cavity. A matching sleeve 17 is integrally connected to the top of the adjusting sleeve 2. A plurality of positioning posts 11 are movably assembled on the installation pipe 1. A second spring 16 is installed on the positioning posts 11. A plurality of annular positioning grooves 14 are provided on the regulating pipe 3. The positioning posts 11 are abutted in the corresponding annular positioning grooves 14.

[0025] When it is necessary to adjust the angle of the air pressure detection gauge 7, it can be adjusted through the angle adjustment component. When it is necessary to adjust the length of the air pressure detection gauge 7, first press the adjustment sleeve 2 upward. The matching sleeve 17 has a conical structure. When pressing the adjustment sleeve 2 upward, the adjustment sleeve 2 will disengage from the positioning post 11. At this time, the positioning post 11 will move outward under the action of the second spring 16, and the positioning post 11 will disengage from the current annular positioning groove 11. Then, the user can pull the adjustment tube 3 up and down to avoid the air pressure detection gauge 7 being blocked by other devices by extending or shortening its length. When the length of the air pressure detection gauge 7 is adjusted appropriately, release the adjustment sleeve 2. The adjustment sleeve 2 will move downward under the action of the first spring 12, and the matching sleeve 17 will squeeze the positioning post 11 to move inward. The positioning post 11 will abut in the adjusted annular positioning groove 14, thereby determining and positioning the lengths of the installation tube 1 and the adjustment tube 3.

[0026] The angle adjustment component includes fixing parts 4 on the left and right sides. An air delivery cavity is provided inside the fixing parts 4. The fixing parts 4 are fixedly installed on the adjustment tube 3. The air delivery cavity is fixedly communicated with the inside of the adjustment tube 3. A rotating shaft 9 is rotatably penetrated through the fixing parts 4. A cavity is provided inside the rotating shaft 9. A number of through holes 19 communicating with the cavity are provided on the rotating shaft 9. A connecting tube 6 communicating with the cavity is fixedly communicated on the rotating shaft 9. An air intake sleeve 5 is fixedly installed at the bottom of the air pressure detection gauge 7. The connecting tube 6 is fixedly communicated with the inside of the air intake sleeve 5.

[0027] During detection, the gas inside the pressure vessel will first enter the installation tube 1, then the gas enters the adjustment tube 3 through the installation tube 1, then the gas enters the air delivery cavity in the fixing part 4, and then the gas enters the cavity of the rotating shaft 19 through the through hole 19. Then the gas enters the air intake sleeve 5 through the connecting tube 6, and finally the gas enters the air pressure detection gauge 7 for air pressure detection. When adjusting the angle of the air pressure detection gauge 7, the rotating shaft 9 can be rotated. When the rotating shaft 9 rotates, it can drive the air pressure detection gauge 7 to rotate, thereby detecting the angle of the air pressure detection gauge 7. After the angle adjustment is completed, rotate the rotating sleeve 8. The rotating sleeve 8 can tightly abut against the fixing part 4, thereby positioning the angle of the air pressure detection gauge 7 and further facilitating the user to observe the air pressure detection gauge 7.

[0028] The through hole 19 communicates with the air delivery cavity inside the fixing part 4.

[0029] A rotating sleeve 8 is threadedly connected to the outer surface of the rotating shaft 9. The rotating sleeve 8 abuts against the fixing part 4.

[0030] A number of anti-slip protrusions are fixedly connected to the outer surface of the rotating sleeve 8 to increase the friction of the rotating sleeve 8.

[0031] The interior of the installation pipe 1 is provided with a limiting cavity 13. The bottom of the adjusting pipe 3 is fixedly connected with a limiting slider 10. The limiting slider 10 is slidably connected with the interior of the limiting cavity 13. A plurality of annular installation grooves 15 are formed in the interior of the installation pipe 1. An annular sealing ring is installed in the annular installation groove 15. A rubber sealing ring is installed on the outer surface of the limiting slider 10.

[0032] The annular sealing ring and the rubber sealing ring are provided to improve the sealing performance between the installation pipe 1 and the adjusting pipe 3 and prevent air leakage.

[0033] Working principle: During detection, the gas inside the pressure vessel will first enter the installation pipe 1, then enter the adjusting pipe 3 through the installation pipe 1, then enter the air delivery cavity in the fixing part 4, and then enter the cavity of the rotating shaft 19 through the through hole 19. After that, the gas enters the air inlet sleeve 5 through the connecting pipe 6, and finally enters the pressure gauge 7 for pressure detection.

[0034] When adjusting the angle of the pressure gauge 7, the rotating shaft 9 can be rotated. When the rotating shaft 9 rotates, it can drive the pressure gauge 7 to rotate, so as to adjust the angle of the pressure gauge 7. After the angle adjustment is completed, rotate the rotating sleeve 8. The rotating sleeve 8 can tightly abut against the fixing part 4, thereby positioning the angle of the pressure gauge 7 and further facilitating the personnel to observe the pressure gauge 7.

[0035] When the length of the pressure gauge 7 needs to be adjusted, first press the adjusting sleeve 2 upward. The matching sleeve 17 is conical. When pressing the adjusting sleeve 2 upward, the adjusting sleeve 2 will disengage from the positioning post 11. At this time, the positioning post 11 will move outward under the action of the second spring 16, and the positioning post 11 will disengage from the current annular positioning groove 11. Then the personnel can pull the adjusting pipe 3 up and down to avoid the dial of the gas detector being blocked by other equipment by extending or shortening the length of the pressure gauge 7. When the length of the pressure gauge 7 is adjusted appropriately, release the adjusting sleeve 2. The adjusting sleeve 2 will move downward under the action of the first spring 12, and the matching sleeve 17 will squeeze the positioning post 11 to move inward. The positioning post 11 will abut against the adjusted annular positioning groove 14, thereby determining and positioning the length of the installation pipe 1 and the adjusting pipe 3.

[0036] This air pressure detector can adjust its length or angle to reduce or avoid the situation that the dial of the gas detector is blocked by other equipment, facilitating the personnel to observe the dial of the gas detector.
