[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] 1. By designing placement slots, magnetic plates, snap-on plates, magnetic blocks and snap-on holes, when the hydraulic cylinder to be tested needs to be tested, the telescopic rod part of the hydraulic cylinder to be tested is placed inside the slide plate and passed through the snap-on plate. When it is necessary to test hydraulic cylinders of different formations, it is only necessary to pull the tension spring so that the pull ring will apply tension to the pull rope, causing the pull rope to drive the snap pin to move up, causing the snap pin to move out of the snap-on hole, and then the snap-on plate can be replaced. When replacing the snap-on plate, it is only necessary to put the snap-on plate into the placement slot, and then use the magnetic block to adsorb the magnetic plate to fix the snap-on plate. After fixing, release the pull ring so that the snap pin enters the snap-on hole under the potential energy of the spring, thereby completing the replacement of the snap-on plate. The above design makes the snap-on plate more convenient during replacement.

[0029] 2. By designing the limit hole and the limit rod, when the hydraulic cylinder to be tested is tested, it is only necessary to insert the limit rod into the movable plate so that the limit rod extends into the limit hole to fix the movable plate. When the hydraulic cylinder to be tested is subjected to force, since the cavity in the limit rod is filled with non-Newtonian fluid, the strength of the limit rod increases during the force-bearing process, thereby improving the strength of the movable plate during the testing process of the hydraulic cylinder to be tested.

[0039] See also Figure 1-Figure 5 A magnetic block 74 is fixedly set inside the clamping plate 73. The magnetism of the magnetic block 74 is opposite to that of the magnetic plate 72. The magnetic attraction between the magnetic plate 72 and the magnetic block 74 is used to fix the clamping plate 73 in the placement groove 71. A clamping hole 75 is opened in the middle of the top surface of the clamping plate 73.

[0040] See also Figure 1-Figure 5 A movable cavity 76 is provided inside the slide plate 7 at the upper side of the placement groove 71, and a magnetic slider 77 is slidably connected inside the movable cavity 76. A spring 78 is fixedly welded to the middle part of the top surface of the magnetic slider 77, and the top of the spring 78 is fixedly welded to the top surface of the movable cavity 76. A bayonet pin 79 is fixedly sleeved on the middle part of the top surface of the magnetic slider 77 and on the inner side of the spring 78. The bayonet pin 79 cooperates with the bayonet hole 75. When the bayonet pin 79 is located in the bayonet hole 75, the bayonet plate 73 is fixed by the bayonet pin 79 to improve the stability of the bayonet plate 73.

[0041] See also Figure 1-Figure 5 A pull rope 791 is fixedly connected to the top of the latch pin 79, and one end of the pull rope 791 away from the latch pin 79 extends out of the top surface of the slide plate 7, and one end of the pull rope 791 away from the latch pin 79 is fixedly connected to a pull ring 792, so that the user can use the pull ring 792 to apply tension to the pull rope 791, thereby pulling the latch pin 79 out of the latching hole 75, making it convenient for the latching plate 73 to be taken out of the placement groove 71.

[0042] See also Figure 1-Figure 5 The movable plate 9 is internally slidably connected to a limit rod 91, a cavity 92 is provided inside the limit rod 91, and the interior of the cavity 92 is filled with a non-Newtonian fluid. A limit hole 21 is provided on the top surface of the fixed platform 2 at a position corresponding to the limit rod 91, so as to improve the strength of the limit rod 91, thereby improving the stability of the movable plate 9.

[0043] Working principle: When the hydraulic cylinder 10 to be tested needs to be tested, the hydraulic cylinder 10 to be tested is fixed on the movable plate 9, and then the telescopic rod part of the hydraulic cylinder 10 to be tested passes through the slide plate 7 and the clamping plate 73, and then the movable plate 9 is pushed to move to the testing position, and then the limit rod 91 is placed in the movable plate 9, and the limit rod 91 is prompted to extend into the limit hole 21, and then the loading hydraulic cylinder 4 is turned on to complete the detection of the hydraulic cylinder 10 to be tested. Since the hydraulic cylinder 10 to be tested is subjected to force, the movable plate 9 is also subjected to the force of the loading hydraulic cylinder 4. At this time, the non-Newtonian fluid in the cavity 92 of the limit rod 91 becomes solid due to the force, so that the strength of the limit rod 91 is increased, thereby increasing the stability of the movable plate 9. Secondly, when it is necessary to test hydraulic cylinders with different strokes, When testing, it is only necessary to manually pull the pull ring 792 so that the pull ring 792 applies tension to the pull rope 791, so that the pull rope 791 will drive the latch pin 79 to move up, so that the latch pin 79 moves out of the latch hole 75, and then the latch plate 73 can be taken out from the placement slot 71. When the latch plate 73 is replaced, the magnetic plate 72 is used to adsorb the magnetic block 74 to fix the latch plate 73. At the same time, the magnetic block 74 will adsorb the magnetic slider 77, so that the magnetic slider 77 slides down under the action of magnetic attraction. When the magnetic slider 77 slides down, it will drive the latch pin 79 to slide down, so that the latch pin 79 enters the latch hole 75, thereby fixing the latch plate 73. The above design can facilitate the rapid replacement of the latch plate 73 and can adapt to the detection of hydraulic cylinders with different strokes, thereby improving the applicability of the test bench.
