[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0029] like Figures 1 to 5As shown in the figure, this embodiment provides a testing device for static pressure of a car door interior panel. The testing device for static pressure of a car door interior panel includes a support column 1 and an operating table 2. The top of the support column 1 is fixedly connected to the operating table 2. The operating table 2 is provided with a fixing component 3. The top surface of the operating table 2 is fixedly connected to a mounting frame 4. The mounting frame 4 is provided with a moving component 5.

[0030] The fixing assembly 3 includes a motor 31, the output shaft of which is fixedly connected to a bidirectional threaded rod 33. A movable plate 32 is threadedly connected to the side wall of the bidirectional threaded rod 33. A sliding groove 39 is provided in the movable plate 32, and a baffle plate 35 is slidably connected to the inner wall of the sliding groove 39. Both ends of the baffle plate 35 are fixedly connected to the inner wall of the operating table 2. A fixing block 310 is fixedly connected to the top surface of the movable plate 32. A cleaning blade 311 is fixedly connected to the side wall of the fixing block 310. A clamping plate 34 is fixedly connected to the top surface of the fixing block 310. A telescopic groove 36 is provided in the clamping plate 34. A connecting spring 37 is fixedly connected to the inner wall of 36. One end of the connecting spring 37 is fixedly connected to a telescopic block 38. One end of the motor 31 is fixedly connected to the side wall of the operating table 2. The output shaft of the motor 31 passes through the operating table 2. The bidirectional threaded rod 33 is located inside the operating table 2. A sliding groove is provided on the top surface of the operating table 2. The top surfaces of the fixing block 310 and the cleaning blade 311 pass through the sliding groove in the operating table 2. The clamping plate 34 and the telescopic block 38 are used to limit the position of the door interior panel. By limiting the position, the door interior panel is prevented from being displaced by external factors, which would affect the testing of the door interior panel.

[0031] During use, the door interior panel is placed on the top surface of the control panel 2. The motor 31 is then started, driving the bidirectional threaded rod 33, which in turn drives the moving plate 32. The moving plate 32 then drives the fixing block 310, which in turn drives the clamping plate 34. This, in turn, drives the telescopic block 38 and the connecting spring 37, causing them to conform to the irregular surfaces of the door interior panel and limit its movement. This limiting action prevents the door interior panel from being affected by external factors. The offset affects the testing of the door interior panel, and the moving plate 32 moves the fixing block 310 at the same time. The fixing block 310 moves the cleaning blade 311, which cleans the inner wall of the sliding groove in the operating table 2, preventing some impurities from adhering to the inner wall of the sliding groove in the operating table 2, reducing some of the cleaning workload. Then, the baffle plate 35 is used to protect the bidirectional threaded rod 33, preventing impurities from adhering to the bidirectional threaded rod 33 through the sliding groove on the top surface of the operating table 2. The baffle plate 35 is located at the top of the bidirectional threaded rod 33. Example 2

[0032] Reference Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that: the moving component 5 includes an electric push rod 51, the output shaft of which is fixedly connected to a fixing frame 55, the bottom surface of which is provided with a slot, a pressure tester 56 is provided in the slot of which, both the fixing frame 55 and the pressure tester 56 are provided with threaded holes 57, the inner wall of which is threaded with a threaded pin 58, the bottom end of which is fixedly connected to the top surface of the mounting frame 4, the top surface of which is provided with a round hole, and the inner wall of the round hole of which is fixedly connected with a threaded pin 58. A lubricating cotton 52 is fixedly connected to the door trim panel. An oil inlet pipe 53 is provided on the side wall of the lubricating cotton 52. One end of the oil inlet pipe 53 is provided with a cap. The output shaft of the electric push rod 51 passes through the lubricating cotton 52. A telescopic tube 54 is provided in the output shaft of the electric push rod 51. The top end of the telescopic tube 54 is fixedly connected to the top of the mounting bracket 4, and the bottom end of the telescopic tube 54 is fixedly connected to the top surface of the fixing bracket 55. By using the electric push rod 51 and the lubricating cotton 52, the output shaft of the electric push rod 51 is lubricated by the lubricating cotton 52 while the pressure tester 56 tests the door trim panel, which facilitates maintenance.

[0033] In use, the electric push rod 51 and pressure tester 56 are activated. The electric push rod 51 drives the fixing frame 55, which in turn drives the pressure tester 56, causing it to move downwards. The pressure tester 56 performs a pressure test on the door trim panel. While the pressure tester 56 moves downwards, the output shaft of the electric push rod 51 is lubricated by the lubricating cotton 52. The output shaft of the electric push rod 51 is protected by the telescopic tube 54. When the pressure tester 56 needs maintenance, the threaded pin 58 is rotated to separate it from the threaded hole 57. The pressure tester 56 is then removed for maintenance. After maintenance, the pressure tester 56 is reinstalled at the bottom of the fixing frame 55 and connected and fixed by the threaded pin 58 and the threaded hole 57.
