Abstract
Description
Technical Field
[0001] This utility model is a pressure detection performance testing device, belonging to the technical field of pressure detection devices. Background Technology
[0002] Pressure detection devices are used to monitor and measure pressure changes in a system or environment. These devices are widely used in various industries, including but not limited to automotive, aerospace, petrochemical, medical equipment, and industrial automation. They are crucial for ensuring proper system operation, improving efficiency, and guaranteeing safety. Below is some key information about pressure detection devices, including their composition, working principle, and application scenarios.
[0003] In existing pressure detection devices, the pressure sensor needs to be installed at the pressure-bearing location during the pressure detection process, which can easily lead to sensor misalignment. This necessitates regular calibration of the pressure detection device and affects detection efficiency during operation. There is an urgent need for a pressure detection performance testing device to solve the above-mentioned problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a pressure detection performance testing device to solve the problems mentioned in the background. This invention is highly practical. After the extrusion plate applies pressure to the pressure probe, the pressure probe deforms at the pressure point. The push plate then pushes the extrusion rod to apply pressure to the pressure sensor. The pressure sensor senses the pressure value and the degree of deformation on the surface of the pressure probe, allowing users to easily determine the stress level of the pressure probe. Furthermore, the pressure sensor is embedded in the placement platform, which prevents the placement platform from shifting.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pressure detection performance testing device, including a fixed base, a placement platform fixedly connected to the upper end of the fixed base, a pressure detector body provided on the surface of the placement platform, four sliding rods slidably connected inside the placement platform, a pushing plate fixedly connected to the upper end of the four sliding rods, a squeezing rod fixedly connected to the lower end of the pushing plate, a limiting plate fixedly connected to the lower end of each of the four sliding rods, and a support platform fixedly connected to the lower end of each of the four limiting plates;
[0006] A protective cover is fixedly connected to the upper right end of the fixed chassis. A motor is fixedly connected inside the protective cover. A rotating disk is fixedly connected to the output end of the motor. An electric push rod is fixedly connected to the upper end of the rotating disk. A connecting rod is fixedly connected to the upper end of the electric push rod. A mounting plate is fixedly connected to the lower left end of the connecting rod. A pressing plate is fixedly connected to the lower end of the mounting plate by screws.
[0007] Furthermore, a docking chassis is fixedly connected to the right end of the fixed chassis, and multiple fixing blocks are fixedly connected to the surfaces of both the fixed chassis and the docking chassis.
[0008] Furthermore, a sleeve is fixedly connected to the upper end of the fixed chassis, and the sleeve is rotatably connected to the electric push rod.
[0009] Furthermore, a support platform is fixedly connected to the upper end of the docking chassis, and a magnetic block is provided at the upper end of the support platform.
[0010] Furthermore, a limit bar is fixedly connected to the upper end of the fixed chassis, and the pressure probe cooperates with the limit bar.
[0011] Furthermore, the extrusion rod is made of a metal material.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a pressure detection performance testing device. Because it adds a connecting rod, an electric push rod, a mounting plate, a pressing plate, a placement platform, a pressure sensor, a pressing rod, a pushing plate, and a motor, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. After the pressing plate applies pressure to the pressure probe, the pressure probe will deform at the pressure position. The pushing plate will then push the pressing rod to apply pressure to the pressure sensor. The pressure sensor senses the pressure value and the degree of deformation on the surface of the pressure probe, which makes it convenient for users to judge the stress level of the pressure probe. Moreover, the pressure sensor is embedded in the placement platform, which can avoid the placement platform from shifting. Attached Figure Description

Detailed Implementation
[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please see Figures 1-4 This utility model provides a technical solution: a pressure detection performance testing device, including a fixed base 1, a placement platform 16 fixedly connected to the upper end of the fixed base 1, a pressure detector 4 disposed on the surface of the placement platform 16, four sliding rods 20 slidably connected inside the placement platform 16, a pushing plate 14 fixedly connected to the upper end of the four sliding rods 20, a squeezing rod 15 fixedly connected to the lower end of the pushing plate 14, a limiting plate 21 fixedly connected to the lower end of each of the four sliding rods 20, a support platform 11 fixedly connected to the lower end of each of the four limiting plates 21, and a protective cover 10 fixedly connected to the upper right end of the fixed base 1. A motor 18 is fixedly connected inside the device. A rotating disk 17 is fixedly connected to the output end of the motor 18. An electric push rod 8 is fixedly connected to the upper end of the rotating disk 17. A connecting rod 6 is fixedly connected to the upper end of the electric push rod 8. A mounting disk 7 is fixedly connected to the lower left end of the connecting rod 6. A pressing disk 5 is fixedly connected to the lower end of the mounting disk 7 by screws. This design solves the problem that in the original device, the pressure sensor needs to be installed at the pressure-bearing position during the pressure detection process, which causes the pressure sensor to be prone to displacement and requires regular calibration of the pressure detection device, thus affecting the detection efficiency during operation.
[0021] As the first embodiment of this utility model: A docking base 12 is fixedly connected to the right end of the fixed base 1. Multiple fixing blocks 2 are fixedly connected to the surfaces of both the fixed base 1 and the docking base 12. The docking base 12, installed on the right end of the fixed base 1, can be used to install a support platform 11, enabling it to support the extrusion plate 5, reduce the stress on the connecting rod 6, and prevent deformation of the connecting rod 6. The fixing blocks 2 installed on the surface of the fixed base 1 can be used to fix the fixed base 1 to the workbench using screws. A sleeve 9 is fixedly connected to the upper end of the fixed base 1. The sleeve 9 is rotatably connected to the electric push rod 8. The sleeve 9 installed on the fixed base 1 can support the electric push rod 8 as it rotates on the protective cover 10, increasing the stress on the electric push rod 8 as it moves the extrusion plate 5. A support platform 11 is fixedly connected to the upper end of the docking chassis 12. A magnetic block 19 is installed on the upper end of the support platform 11. The support platform 11, mounted on the docking chassis 12, can be used to temporarily place the extrusion plate 5. When the equipment is idle, it reduces the stress on the connecting rod 6 and increases its service life. The magnetic block 19 on the support platform 11 can hold the extrusion plate 5 and fix it to the support platform 11. A limit bar 3 is fixedly connected to the upper end of the fixed chassis 1. The pressure probe 4 cooperates with the limit bar 3. The limit bar 3 on the fixed chassis 1 can limit the pressure probe 4 to the surface of the placement platform 16 and the fixed chassis 1, preventing displacement when the pressure probe 4 is subjected to the pressure of the extrusion plate 5. The extrusion rod 15 is made of metal, preventing breakage during repeated testing.
[0022] As a second embodiment of this utility model: First, the pressure probe 4 is placed on the fixed base 1, and the outer edge of the pressure probe 4 is limited to the limit bar 3. Then, the motor 18 is controlled to drive the extrusion plate 5 to move to the upper end of the pressure probe 4. The electric push rod 8 drives the extrusion plate 5 to apply pressure to the pressure probe 4. When the pressure probe 4 is deformed by the pressure of the extrusion plate 5, the protruding part of the pressure probe 4 will press the push plate 14 downward. At the same time, the push plate 14 applies pressure to the pressure sensor 13 through the extrusion rod 15. The user judges the stress of the pressure probe 4 according to the degree of deformation of the pressure probe 4 and the value detected by the pressure sensor 13.
