[0021] Example 1

[0022] Combination Figures 1-4 A solenoid valve life test bench for easy fixation includes a bench body 1. A vertical plate 9 is fixedly installed at the upper end of the bench body 1. A groove 10 is formed at the upper end of the vertical plate 9. A movable part 13 is slidably installed inside the groove 10. An installation groove 14 is formed at the upper end of the movable part 13. A test pen 15 connected to a multimeter is installed inside the installation groove 14. A placement plate 2 is fixedly installed at the upper end of the placement plate 1. A fastening structure 3 is provided at the upper end of the placement plate 2. The fastening structure 3 includes a fastening seat 4 fixedly installed at the upper end of the placement plate 2. A fixing plate 5 is fixedly installed at the rear side of the upper end of the fastening seat 4. A movable rod 6 is movably installed inside the front end of the fastening seat 4. A movable plate 51 is fixedly installed at the rear end of the movable rod 6. A spring 7 is provided on the outer wall of the movable rod 6. A solenoid valve body is arranged between the movable plate 51 and the fixing plate 5.

[0023] See Figure 1 and Figure 4 Furthermore, the upper end of the movable part 13 is fixedly provided with a mounting plate 16, and the lower end of the mounting plate 16 is fixedly provided with two pressing blocks 17. The lower ends of the pressing blocks 17 enter the interior of the mounting groove 14. The front and rear ends of the upper side of the movable part 13 are fixedly provided with screws 18. The output end of the screws 18 passes through the mounting plate 16 and is provided with a nut on the outer wall. Assembly plates are fixedly provided on both sides of the platform 1. A pull-out box is installed at the front end of the platform 1. A pull plate 8 is fixedly provided at the front end of the movable rod 6.

[0024] Specifically, the mounting plate 16 is used to set the squeezing block 17, which squeezes and tightens the test pen 15 to ensure the stable placement of the test pen 15. The screw 18 passes through the mounting plate 16 and cooperates with the nut to realize the installation of the mounting plate 16. The pull plate 8 facilitates the pulling of the movable rod 6.

[0025] Example 2

[0026] See Figure 4 Furthermore, based on Embodiment 1, a fixing frame 11 is fixedly provided on one side of the vertical plate 9, and a lead screw 12 is provided inside the fixing frame 11. One end of the lead screw 12 is rotatably connected to one end of the moving part 13.

[0027] Specifically, the fixing frame 11 is used to set the lead screw 12, and the lead screw 12 is used to adjust the position of the moving part 13 so that one end of the test pen 15 contacts the detection end of the solenoid valve to realize the power-on test.

[0028] In actual operation, when it is necessary to test the solenoid valve by powering it on, pull the movable rod 6, so that the movable plate 51 moves to the front end, compresses the spring 7, and puts the solenoid valve body to be tested between the movable plate 51 and the fixed plate 5. Release the movable rod 6 to quickly fix the solenoid valve.

[0029] After fixing, rotate the lead screw 12, which causes the lead screw 12 to drive the moving part 13 to move to one side, which in turn causes the moving part 13 to drive the test pen 15 to move to one side, so that the test head of the test pen 15 contacts the detection end of the solenoid valve. When recording the detection current and voltage, the test pen 15 will not separate from the detection end of the solenoid valve.
