[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 of the embodiments.

[0023] Please refer to Figures 1 to 5, the present utility model provides a technical solution: an improved pressure measuring device, including a workbench 1 and a test object 2. A support frame 3 is installed on the top of the workbench 1. A test bench 4 is installed on the top of the workbench 1 and on one side of the support frame 3. A hydraulic rod 7 is fixedly installed on the top of the support frame 3. The output end of the hydraulic rod 7 is fixedly connected with an installer 8 above the test bench 4. A pressing plate 9 is threadedly connected to the bottom of the installer 8. A pressure sensor 5 is installed inside the workbench 1 and at the bottom of the test bench 4. Under the action of the hydraulic rod 7, the pressing plate 9 rises and falls accordingly, and presses the test object 2. The pressure sensor 5 then detects the pressure borne by the test object 2. A threaded column 30 is installed at the bottom of the installer 8. A threaded hole 31 matching the threaded column 30 is opened inside the pressing plate 9. The threaded connection structure facilitates the replacement of the pressing plate 9. Multiple convex grooves 10 are opened inside the test bench 4. Convex blocks 11 are slidably connected inside the multiple convex grooves 10. A positioning block 12 is fixedly connected to the top of the convex block 11. A lead screw 13 is rotatably connected inside the convex groove 10. The lead screw 13 penetrates through the convex block 11 and is threadedly connected to the convex block 11. When the lead screw 13 rotates, the convex block 11 can drive the positioning block 12 to displace. A groove 14 is opened inside the test bench 4 and between the multiple convex grooves 10. Multiple first bevel gears 15 are rotatably connected inside the groove 14. A second bevel gear 16 is rotatably connected inside the groove 14 and at the bottom of the multiple first bevel gears 15. The multiple first bevel gears 15 are all meshed with the second bevel gear 16. The multiple first bevel gears 15 are respectively connected to the multiple lead screws 13. Through the meshing of the multiple first bevel gears 15 and the second bevel gear 16, the multiple first bevel gears 15 are driven to transmit power, and the multiple lead screws 13 can rotate simultaneously, driving the multiple positioning blocks 12 to displace simultaneously to clamp the test object 2, facilitating the standardization of the position of the test object 2 and making the detection more accurate. A turning handle 17 is rotatably connected to one side of the test bench 4. The turning handle 17 is connected to one of the lead screws 13. A telescopic spring 18 is connected to one side of the positioning block 12. One end of the telescopic spring 18 is connected to a limiting block 19. Under the action of the telescopic spring 18, when the test object 2 deforms, the limiting block 19 can be automatically displaced when being squeezed. A first gear 20 is rotatably connected inside the support frame 3 and outside the pressing plate 9. A support 21 is connected to the bottom of the first gear 20. A convex sliding groove 32 is opened inside the support 21. A convex slider 22 is slidably connected inside the convex sliding groove 32. A distance detector 23 is connected to one side of the convex slider 22 to detect the distance from the test object 2, and according to the change of the distance, it is convenient to judge the deformation of the test object 2. A controller 6 is installed on one side of the support frame 3. The controller 6 is electrically connected to the pressure sensor 5 and the distance detector 23 respectively. A display screen is arranged on one side of the controller 6, facilitating the display of the pressure magnitude and deformation degree borne by the test object 2. A second gear 24 is rotatably connected inside the support frame 3 and on one side of the first gear 20.The second gear 24 meshes with the first gear 20, so that the distance detector 23 rotates, and at the same time, the first gear 20 and the bracket 21 rotate. The distance detector 23 on the bracket 21 moves around the detection object 2, which is convenient for adjusting the position of the distance detector 23 and performing a full-scale detection of the detection object 2. The first motor 25 is installed on the top of the support frame 3 and on one side of the hydraulic rod 7. The output end of the first motor 25 is connected to the second gear 24 to provide power for the rotation of the second gear 24. The inside of the bracket 21 and the top of the convex slide groove 32 A cavity 26 is provided, and a reel 27 is rotatably connected inside the cavity 26. A traction rope 28 is wound around the outside of the axis of the reel 27. One end of the traction rope 28 is connected to the convex slider 22. A second motor 29 is installed on one side of the bracket 21. The output end of the second motor 29 is connected to the reel 27 to drive the reel 27 to rotate. While controlling the retraction and release of the traction rope 28, the convex slider 22 and the distance detector 23 are driven to rise and fall through the connection between one end of the traction rope 28 and the convex slider 22 on one side of the distance detector 23, so as to facilitate the adjustment of the height of the distance detector 23.

[0024] In summary, when the improved pressure measuring device is used, after the detection object 2 is placed on the detection platform 4, the screw rod 13 in one of the convex grooves 10 in the detection platform 4 is driven to rotate by the turning handle 17. Since the multiple first bevel gears 15 in the groove 14 are all meshed with the second bevel gear 16, the multiple first bevel gears 15 are respectively connected to the multiple screw rods 13, so that the rotation of the multiple first bevel gears 15 and the second bevel gear 16 is consistent, and the multiple screw rods 13 rotate accordingly. The multiple screw rods 13 are respectively connected to the threaded connection of the multiple convex blocks 11, driving the positioning block 12 to move, and the limit blocks 19 on one side of the multiple positioning blocks 12 fix the detection object 2 accordingly, and standardize the position of the detection object 2. At this time, the hydraulic rod 7 pushes the pressure plate 9 to move downward to squeeze the detection object 2. The pressure sensor 5 in the workbench 1 senses the change in pressure and performs pressure detection on the detection object 2. At the same time, the distance detector 23 determines the deformation of the detection object 2 according to the change in the distance from the detection object 2. The pressure sensor 5 and the distance detector 23 transmit the information to the controller 6, which is displayed on the display screen to measure the changes of the detection object 2 under different pressures. When the limit block 19 is squeezed by the deformation of the detection object 2, it automatically moves through the deformation of the telescopic spring 18. Under the action of the engagement of the first gear 20 and the second gear 24, the first motor 25 drives the second gear 24 to rotate according to demand, which can drive the first gear 20 and the bracket 21 to rotate, so that the distance detector 23 moves around the detection object 2 and adjusts the position of the distance detector 23.

[0025] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
