[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] Please see Figure 1-5 As shown, this embodiment is a performance testing bench for the research and development of diaphragm compressors, comprising:

[0036] Test bench 100, with a connecting frame 200 in the middle of the test bench 100, and a first connecting plate 210 and a second connecting plate 220 symmetrically fixedly connected at both ends of the bottom surface of the connecting frame 200;

[0037] The lifting and lowering mechanism is located on both sides of the connecting frame 200. The lifting and lowering mechanism includes a driving rod 310, a driven rod 320, a rotating shaft 330, a horizontal plate 340, and a first motor 350.

[0038] One end of the active rod 310 is rotatably connected to the second connecting plate 220, and one end of the driven rod 320 is rotatably connected to the first connecting plate 210. The horizontal plate 340 is fixedly connected to the bottom of the test bench 100, and the rotating shaft 330 is rotatably connected to the horizontal plate 340. The other end of the active rod 310 is fixedly connected to the rotating shaft 330. The first motor 350 is fixed to the side of the test bench 100, and the other end of the rotating shaft 330 is fixedly connected to the power output end of the first motor 350. When the first motor 350 is started, the first motor 350 drives the rotating shaft 330 to rotate, and the rotating shaft 330 drives the active rod 310 to rotate. The other end of the active rod 310 drives the second connecting plate 220 to descend, causing the connecting frame 200 to descend and extend outward. The connecting frame 200 drives the first connecting plate 210 to descend, and the descent of the first connecting plate 210 causes one end of the driven rod 320 to move, while the other end rotates on the first motor 350, so that the connecting frame 200 is flush with the bottom surface, making it convenient to move the diaphragm compressor onto the connecting frame 200.

[0039] It also includes a fixing mechanism, which includes a pin 510, a large round hole 520, a small round hole 530, a push pin 540, a cylinder 550, and a first spring 560;

[0040] A large circular hole 520 is opened on the upper part of the insertion post 510, and a small circular hole 530 is opened on the lower part of the insertion post 510. The pressing post 540 is slidably connected in the large circular hole 520, and the cylinder 550 is fixed at the bottom of the pressing post 540. The cylinder 550 slides in the small circular hole 530 and passes through the first spring 560. The two ends of the first spring 560 are respectively fixed to the bottom surface of the pressing post 540 and the bottom of the large circular hole 520. After the diaphragm compressor moves to the connecting frame 200, the insertion post 510 is inserted into the insertion hole 230 after passing through the fixing hole of the diaphragm compressor chassis. Pressing the pressing post 540 compresses the first spring 560, and the pressing post 540 drives the cylinder 550 to descend in the small circular hole 530.

[0041] The fixing mechanism also includes a limiting component, which includes a sliding hole 571, a limiting head 572, a sliding post 573, and a second spring 574;

[0042] A sliding hole 571 is formed at the bottom of the side wall of the small round hole 530. The limiting head 572 is slidably connected in the sliding hole 571. The sliding column 573 is fixedly connected to the side wall of the limiting head 572. The sliding column 573 passes through the second spring 574. The two ends of the second spring 574 are fixedly connected to the side wall of the limiting head 572 and the bottom of the sliding hole 571, respectively. A groove 551 is formed at the bottom of the side wall of the cylinder 550. When the limiting head 572 extends out of the sliding hole 571, the second spring 574 is in a stretched state. When the small round hole 530 descends and 531 aligns with the sliding hole 571, the second spring 574 rebounds and the limiting head 572 retracts into the sliding hole 571, and one end of the sliding column 573 extends out of the sliding hole 571 and fits against the groove 551.

[0043] The top surface of the connecting frame 200 is provided with multiple insertion holes 230, and the bottom of the insertion hole 230 is provided with a limiting groove 231. The limiting head 572 is embedded in the limiting groove 231. By the limiting head 572 being embedded in the limiting groove 231, the sliding hole 571 is fixed in the insertion hole 230, thereby fixing the diaphragm compressor and the connecting frame 200.

[0044] Working principle: When testing the diaphragm compressor, start the first motor 350. The first motor 350 drives the rotating shaft 330 to rotate, which in turn drives the drive rod 310 to rotate. The other end of the drive rod 310 drives the second connecting plate 220 to descend, causing the connecting frame 200 to descend and extend outward. The connecting frame 200 drives the first connecting plate 210 to descend, causing one end of the driven rod 320 to move while the other end rotates on the first motor 350, making the connecting frame 200 flush with the bottom surface. This facilitates moving the diaphragm compressor onto the connecting frame 200. After aligning the fixing holes on the diaphragm compressor chassis with the first connecting plate 210 on the connecting frame 200, press down the actuating column 540 to compress the first spring 560. The actuating column 540 drives the cylinder 550 to descend within the small circular hole 530. When hole 530 descends, 531 aligns with sliding hole 571. At this time, the second spring 574 rebounds, causing the limiting head 572 to retract into sliding hole 571. One end of sliding column 573 extends out of sliding hole 571 and fits into groove 551. Then, insert column 510 passes through the fixing hole of diaphragm compressor chassis and inserts into insertion hole 230. When insert column 510 is inserted to the bottom of insertion hole 230, release pressing column 540. The first spring 560 rebounds, causing cylinder 550 to rise. As cylinder 550 rises, one end of 5573 is pressed into sliding hole 571 along the arc surface of groove 551, and the second spring 574 is pulled up. Sliding column 573 drives limiting head 572 to extend out of sliding hole 571 and embed into limiting groove 231, fixing sliding hole 571 in insertion hole 230, thereby fixing diaphragm compressor and connecting frame 200.

[0045] In this step, the first motor 350 drives the rotating shaft 330 to rotate, which in turn drives the active rod 310 to rotate. The other end of the active rod 310 drives the second connecting plate 220 to descend, causing the connecting frame 200 to descend and extend outward. The connecting frame 200 drives the driven rod 320 to rotate, so that the connecting frame 200 is in contact with the ground, making it easy for the diaphragm compressor to move onto the connecting frame 200. Then, the first motor 350 reverses to drive the connecting frame 200 to rise, which can quickly move the diaphragm compressor onto the test bench and improve testing efficiency.

[0046] Please see Figure 1-5 As shown, in this embodiment, based on the above structure, the quick-release assembly 220 also includes a support mechanism. There are four support mechanisms, including a square tube 410, a second motor 420, a lead screw 430, and a support rod 440.

[0047] The square tube 410 is fixedly connected to the bottom of the test bench 100. The second motor 420 is fixed to the side wall of the square tube 410. The lead screw 430 is fixedly connected to the power output end of the second motor 420. The support rod 440 is slidably connected inside the square tube 410. The support rod 440 is threadedly connected to the lead screw 430. The second motor 420 drives the square tube 410 to rotate, so that the support rod 440 threadedly connected to the square tube 410 slides inside the square tube 410. One end of the support rod 440 extends out of the square tube 410 and fits against the bottom of the connecting frame 200, providing an additional support point for the connecting frame 200.

[0048] A sliding plate 441 is fixed in the middle of the support rod 440, and a baffle 411 is fixed at one end of the square tube 410. The sliding plate 441 slides inside the square tube 410. The baffle 411 fits against the support rod 440 and blocks the sliding plate 441 to prevent the support rod 440 from sliding out of the square tube 410 or from extending too far, thus reducing the supporting force.

[0049] Working principle: After the connecting frame 200 fixes the diaphragm compressor and rises to the top of the test bench 100, the second motor 420 is started. The second motor 420 drives the square tube 410 to rotate, so that the support rod 440, which is threadedly connected to the square tube 410, slides inside the square tube 410, and one end of the support rod 440 extends out of the square tube 410 and fits against the bottom of the connecting frame 200, providing an additional support point for the connecting frame 200;

[0050] In this step, the second motor 420 drives the lead screw 430 to rotate, causing the support rod 440 to extend from the square tube 410 and fit against the bottom of the connecting frame 200, providing an additional support point for the connecting frame 200 and preventing the diaphragm compressor from bending the driving rod 310 and driven rod 320 and causing them to fall off during test operation.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
