[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0020] like Figure 1 , Figure 2 , Figure 3 The illustration shows an embodiment of the present invention, which discloses a testing fixture for a solenoid valve, including a support base 1, a limiting seat 2, and a limiting groove 3. The support base 1 is used to fix the valve to an external fixture frame, the limiting seat 2 is disposed on the support base 1, and the limiting groove 3 is disposed on the limiting seat 2. The inner contour of the limiting groove 3 matches the bottom contour of the solenoid valve, so that the solenoid valve can be tightly engaged in the limiting groove 3, thereby achieving reliable fixation of the solenoid valve and avoiding the inaccuracy of the test results due to the tilting of the solenoid valve during the test.

[0021] In one embodiment, such as Figure 1 , Figure 2 As shown, the support base 1 includes a support plate 11 and a support block 12. The support plate 11 is used to fix it on an external tooling frame, and the limiting seat 2 is disposed on the support block 12. The support plate 11 has a dovetail-shaped cross-section, and the bottom of the support block 12 is provided with a dovetail groove 13. The support plate 11 and the dovetail groove 13 are horizontally slidably engaged, that is, the support block 12 is horizontally slidably connected to the support plate 11, so that the position of the solenoid valve can be adjusted. This achieves both the forward and backward adjustment of the solenoid valve for testing and meets the space requirements for disassembly and assembly of the solenoid valve.

[0022] In one embodiment, such as Figure 1 , Figure 2As shown, the support plate 11 is provided with a pair of strip holes 14. The length direction of the strip holes 14 is parallel to the sliding direction of the support block 12, and the strip holes 14 are for fastening bolts to pass through, so that the support plate 11 can be connected to the external tooling frame by fastening bolts, thereby improving the connection stability between the support plate 11 and the external tooling frame.

[0023] In one embodiment, such as Figure 1 , Figure 2 As shown, the support block 12 has a first mounting groove 15 on its side wall and a second mounting groove 16 on its upper surface. The first mounting groove 15 is for mounting a connector, and the second mounting groove 16 is for mounting a power switch. The support block 12 also has a through hole 17 connecting the first mounting groove 15 and the second mounting groove 16, allowing the connector's wires to pass through the through hole 17 and connect to the power switch. The connector is used to connect to the wiring plug of the solenoid valve, enabling the power switch to control the opening and closing of the solenoid valve, and allowing the solenoid valve to be quickly installed and removed.

[0024] In one embodiment, such as Figure 1 , Figure 2 As shown, the side wall of the support block 12 is provided with a clearance opening 18 that communicates with the second mounting groove 16. After the power switch is installed in the second mounting groove 16, the button of the power switch is aligned with the clearance opening 18 to prevent personnel from accidentally touching the button of the power switch, thereby providing safety protection.

[0025] In one embodiment, such as Figure 1 , Figure 3 As shown, the limiting seat 2 includes a limiting post 21 and a limiting plate 22. The limiting post 21 is cylindrical and is vertically mounted on the support block 12. The limiting plate 22 is disc-shaped and is coaxially and integrally formed and connected to the top of the limiting post 21. The limiting groove 3 is provided on the limiting plate 22.

[0026] In one embodiment, such as Figure 1 , Figure 3 As shown, the upper surface of the support block 12 is provided with a guide groove 23, the limiting post 21 is vertically slidably engaged with the guide groove 23, and the support block 12 is provided with a control part 24 for controlling the vertical movement of the limiting post 21 so that the height of the solenoid valve can be adjusted.

[0027] In one embodiment, such as Figure 1 , Figure 3As shown, the control unit 24 includes a control nut 241, a threaded portion 242, and an anti-rotation portion 243. The control nut 241 is rotatably connected to the support block 12, and the limiting post 21 passes through the control nut 241. The threaded portion 242 is disposed on the limiting post 21, and the threaded portion 242 is threadedly engaged with the control nut 241. The anti-rotation portion 243 is disposed on the support block 12 and the limiting post 21, and the anti-rotation portion 243 is used to limit the rotation of the limiting post 21, so that after the operator rotates the control nut 241, the limiting post 21 can move vertically, thereby achieving precise fine-tuning of the test height.

[0028] In one embodiment, such as Figure 1 , Figure 3 As shown, the anti-rotation part 243 includes an anti-rotation post 244 and an anti-rotation groove 245. The anti-rotation post 244 is vertically fixed to the bottom of the limiting post 21, and the anti-rotation groove 245 is disposed at the bottom of the guide groove 23. The outer contour of the anti-rotation post 244 and the inner contour of the anti-rotation groove 245 are rectangular, and the anti-rotation post 244 and the anti-rotation groove 245 slide vertically to achieve circumferential limiting of the limiting post 21.

[0029] As can be seen from the above, this testing fixture can be used to safely, quickly, conveniently and reliably test the performance of solenoid valves. It is especially suitable for land maintenance testing scenarios, which can improve both work efficiency and measurement accuracy.
