The other end of the support plate 110 is provided with a telescopic rod 19, and the other end of the support plate 110 is fixedly connected to one end of the telescopic rod 19. The other end of the telescopic rod 19 is fixedly connected to the bottom of the bottom bracket 11. The top of the side panel 13 is provided with an arc plate 14, and the top of the side panel 13 is in contact with one end of the arc plate 14. A fixed plate 111 is provided on one side of the side panel 13, and one side of the side panel 13 is fixedly connected to one end of the fixed plate 111. The fixed plate 111 is fixedly connected to one end of the fixed plate 111. 1 is provided with a guide rod 113 at the top, the top of the fixing plate 111 is vertically fixed to the bottom end of the guide rod 113, the top of the guide rod 113 is provided with a fixing plate 2 112, the top of the guide rod 113 is connected to the inside of the fixing plate 2 112, one end of the fixing plate 2 112 is fixedly connected to one side of the arc plate 14, and a limiting rod 114 is provided inside the fixing plate 2 112. The inside of the fixing plate 2 112 corresponds to one end of the limiting rod 114, and one side of the limiting rod 114 is engaged with one side of the guide rod 113. A sealing plug is provided inside one side of the transparent box 12 16. The interior of the transparent box 12 is connected with the outer side of the sealing plug 16. The outer side of the sealing plug 16 corresponds to the interior of the motor housing 15. A connecting rod 17 is provided at one end of the side of the sealing plug 16. One end of the side of the sealing plug 16 is fixedly connected to the top of the connecting rod 17. A screw rod 18 is provided at the bottom end of the connecting rod 17. The bottom end of the connecting rod 17 is threadedly connected to the outer side of the screw rod 18. The outer side of the screw rod 18 is rotatably connected to one end of the bottom side of the base 11. A control panel 115 is provided on one side of the transparent box 12. One side of the transparent box 12 is fixedly connected to the connecting end of the control panel 115.
[0025] In this embodiment, when the motor housing 15 needs to be subjected to a pressure test, it is placed inside the transparent box 12 and between the two side panels 13. Then, the curved plate 14 is vertically aligned with the side panels 13 so that the inner side of the curved plate 14 corresponds to the outer side of the motor housing 15. At this time, the limiting rod 114 is inserted into the interior of the second fixing plate 112 so that it engages with the guide rod 113 and fixes the curved plate 14 to the side panels 13. Then, the pressure value is set on the control console 115 so that the telescopic rod 19 is extended to drag the side panels 13 and the curved plate 14 downward, thereby simulating the pressure that the motor housing 15 may withstand in actual use, so as to ensure that its structure can withstand the expected load and ensure the quality and safety of the product. This test can help confirm the durability and stability of the motor housing 15 and ensure that it meets relevant standards and requirements.
[0026] Secondly, when testing in a transparent box 12 containing water, in order to ensure a certain degree of sealing inside the motor housing 15, after placing it between the two side panels 13, the sealing plug 16 on the connecting rod 17 is displaced in different directions by rotating the screw 18 and entering the internal end position of the motor housing 15. This operation simulates the pressure and challenges that the motor may face in a humid or liquid environment, to ensure that the motor housing 15 can effectively prevent liquid from penetrating into the interior and maintain its normal function.
[0027] Example 2
[0028] like Figure 1 As shown, the auxiliary mechanism 2 includes a connecting pipe 21 , one end of which is fixedly connected to the interior of the transparent box 12 , and a valve 22 is provided on the top side of the connecting pipe 21 , which is fixedly connected to one end of the valve 22 .
[0029] In this embodiment, by rotating valve 22 to open the passage between connecting tube 21 and transparent box 12, water can flow from the interior of transparent box 12 through connecting tube 21 and ultimately out of the system. This effectively removes water from transparent box 12, allowing for other operations or tests. After drainage, transparent box 12 is free of water, allowing subsequent operations or replacement of water samples. The effect of drainage is to empty the water inside transparent box 12, restoring it to a dry state for the next step. This ensures the accuracy and reliability of the test while also protecting the equipment from the effects of a humid environment.
[0030] Working principle:
[0031] like Figure 1-Figure 4As shown, when the utility model is in use, according to the needs of the user, it is placed inside the transparent box 12 and between the two side panels 13. Then, the curved plate 14 is vertically aligned with the side panels 13 so that the inner side of the curved plate 14 corresponds to the outer side of the motor housing 15. At this time, the limiting rod 114 is inserted into the interior of the second fixing plate 112 so that it engages the guide rod 113 and fixes the curved plate 14 to the side panels 13. Then, the pressure value is set on the control console 115 so that the telescopic rod 19 is extended so that the side panels 13 and the curved plate 14 are dragged downward, thereby simulating the pressure that the motor housing 15 may withstand in actual use. Secondly, in order to ensure a certain degree of sealing inside the motor housing 15, after it is placed between the two side panels 13, the screw rod 18 is rotated so that the sealing plug 16 on the connecting rod 17 is displaced from different directions and enters the internal end position of the motor housing 15. This operation simulates the pressure and challenges that the motor may face in a humid or liquid environment.
[0032] By rotating the valve 22, the passage between the connecting pipe 21 and the transparent box 12 is opened, and water can flow from the inside of the transparent box 12 through the connecting pipe 21 and finally be discharged from the system. This can effectively remove the water from the transparent box 12 so that other operations or tests can be performed. After drainage, there will be no water in the transparent box 12, and subsequent operations or replacement of water samples can be performed.
