Description

Technical Field

[0015] 1. This utility model provides a multifunctional integrated pressure calibrator, which utilizes the cooperation between a pressure calibrator, a crash pad, an angle tilting mechanism, and a fixing component. The tilting angle of the pressure calibrator is adjusted by rotating the angle tilting mechanism, and the tilting angle of the angle tilting mechanism is then positioned by operating the fixing component.

[0025] The system consists of a pressure calibrator 1, a crash pad 2, an angle tilting mechanism 3, a fixing component 4, a data cable 5, a detection head 6, and a storage mechanism 7. The angle tilting mechanism 3 and the fixing component 4 work together to position the tilting angle of the angle tilting mechanism 3, improving the stability of the pressure calibrator 1. The data cable 5 is then wound and secured to the storage mechanism 7 for easy storage.

[0026] like Figure 2As shown, this utility model provides a technical solution for a multifunctional integrated pressure calibrator: the angle tilting mechanism 3 includes two sleeve rods 31, two movable rings 32, two L-shaped brackets 33, a base 34, and a handle 35. The inner walls of the two movable rings 32 are rotatably connected to the middle side of the outer wall of the sleeve rods 31. The top of the L-shaped brackets 33 in the vertical direction is fixedly connected to the outer wall of the movable rings 32. Several positioning grooves 320 are equally spaced on the outer walls of the two movable rings 32 near the rear side of the L-shaped brackets 33. Multiple positioning grooves 320 are formed on the movable rings 32. 20, which serves to limit the tilt angle of the L-shaped bracket 33 by fixing component 4. The left and right ends of the base 34 are fixedly connected to one end of the horizontal surface of the two L-shaped brackets 33. The rear end of the base 34 is provided with a vertically penetrating mounting groove 340. The top of the outer wall of the handle 35 is rotatably connected to the inner wall of the mounting groove 340. The opposite surfaces of the two sleeve rods 31 are fixedly connected to the middle sides of the left and right ends of the pressure calibrator 1. Through the cooperation of the L-shaped bracket 33 and the base 34, the pressure calibrator 1 is tilted and supported.

[0027] like Figure 3 As shown, this utility model provides a technical solution for a multifunctional integrated pressure calibrator: the fixing component 4 includes a U-shaped frame 41, two connecting plates 42, two inserts 43, a sliding rod 44, a semi-circular pull ring 45, and a return spring 46. The tops of the two connecting plates 42 are respectively fixedly connected to the bottom of the U-shaped frame 41 in the vertical direction. The tops of the inserts 43 are fixedly connected to the bottoms of the connecting plates 42. The top of the outer wall of the sliding rod 44 passes through the upper and lower ends of the middle of the transverse surface of the U-shaped frame 41 and is slidably connected to it. The bottom of the semi-circular pull ring 45 is fixedly connected to the top of the transverse surface of the U-shaped frame 41. The part is close to the outside of the slide bar 44. The inside of the return spring 46 is sleeved on the upper side of the outer wall of the slide bar 44. The upper end of the return spring 46 is fixedly connected to the inner surface of the semi-circular pull ring 45. The lower end of the return spring 46 is fixedly connected to the top of the transverse surface of the U-shaped frame 41. The outer walls of the two inserts 43 are respectively inserted into the inside of the two positioning grooves 320. The bottom of the slide bar 44 is fixedly connected to the top of the pressure calibrator 1. The elasticity of the return spring 46 can be used to extend and retract the U-shaped frame 41, which facilitates the positioning effect after the angle tilting mechanism 3 is adjusted.

[0028] like Figure 4As shown, this utility model provides a technical solution for a multifunctional integrated pressure calibrator: the storage mechanism 7 includes a winding column 71, a chuck 72, two clamping plates 73 and two buckle plates 74. The middle part of the chuck 72 is fixedly connected to the rear end of the winding column 71. The outer walls of the left and right ends of the chuck 72 are respectively provided with connecting grooves 720 that pass through the front and rear. One side of the outer wall of the clamping plate 73 is rotatably connected to the inner wall of the connecting groove 720. The clamping plate 73 is fastened and opened along the connecting groove 720, so that the data cable 5 can be wound around the winding column 71 and then clamped on the outer wall of the data cable 5 for limiting, so as to prevent the data cable 5 from falling off. The front end of the winding column 71 is fixedly connected to the back of the pressure calibrator 1, and the front ends of the two buckle plates 74 are respectively fixedly connected to the left and right sides of the back of the pressure calibrator 1 near the winding column 71.

[0029] like Figure 5 As shown, this utility model provides a technical solution for a multifunctional integrated pressure calibrator: two buckle plates 74 each have a slot 740 on their backs at opposite ends, and a magnet 75 is fixedly connected to the inner wall of each slot 740. An iron plate 76 is fixedly connected to the front end of each buckle plate 73 on the side away from the chuck 72. The outer wall of the buckle plate 73 engages with the inside of the slot 740, and the outer wall of the iron plate 76 is magnetically connected to the outer wall of the magnet 75. The buckle plate 73 is fastened into the slot 740 along the connecting groove 720, and the outside of the winding column 71 is locked by the magnetic attraction between the magnet 75 and the iron plate 76.

[0030] The working principle of this multi-functional integrated pressure calibrator will be explained in detail below.

[0031] like Figure 1-5 As shown, when using the pressure calibrator 1 for pressure measurement, the operator lifts the handle 35 to carry the pressure calibrator 1 to the testing position, then pulls the semi-circular pull ring 45 upwards, causing the U-shaped frame 41 to move upwards and compress the return spring 46, thus disengaging the insertion post 43 from the positioning groove 320. Then, the L-shaped bracket 33 is rotated backwards along the pressure calibrator 1. When the L-shaped bracket 33 is adjusted to a suitable tilt angle, the corresponding positioning groove 320 on the movable ring 32 is aligned with the insertion post 43. Then, the force applied to the U-shaped frame 41 is released, and the elasticity of the return spring 46 is used to reset the U-shaped frame 41, thus disengaging the insertion post 43 from the positioning groove 320. The insert 43 is reinserted into the positioning groove 320 to fix the tilt angle of the L-shaped bracket 33, preventing the L-shaped bracket 33 from continuing to rotate. This allows the pressure calibrator 1 to be tilted and supported on the flat surface for measurement and calibration. After the measurement is completed, the two side plates 73 are opened, and the data cable 5 is wound around the winding post 71. After winding, the two side plates 73 are snapped inward along the connecting groove 720 to insert the plates 73 into the slot 740. The iron plate 76 is magnetically fixed to the surface of the magnet plate 75 to limit and lock the outside of the wound data cable 5, making it easy to store the data cable 5.

[0032] The specific type and structure of the pressure calibrator used are all existing products, as are the specific circuit connection structure and control relationship between the pressure calibrator, the data cable, and the test head. These will not be elaborated upon here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
