[0003] However, most of the current gas spring fatigue testing devices on the market use a hydraulic cylinder to reciprocate and press the spring for fatigue detection. Due to the long-term high-frequency reciprocating motion of the hydraulic cylinder, regular maintenance is required, otherwise the hydraulic cylinder is likely to be damaged and malfunction. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the high-frequency pressing detection of the hydraulic cylinder is easy to be damaged and malfunction.

The transmission mechanism is arranged on the base. The transmission mechanism includes a rotating disk and a connecting plate. The rotating disk is rotatably connected to the upper part of the base and penetrates through the base. The connecting plate is slidably connected to the upper part of the rotating disk. A guiding rod is fixedly arranged on the rotating disk, and a guiding groove is formed on the connecting plate. The guiding rod and the guiding groove are slidably connected. Connecting rods are fixedly arranged on both sides of the connecting plate, and the fixing mechanism is fixedly arranged on the upper part of the base.

[0006] Furthermore, the guiding groove is set to an arc-shaped structure, and the radius of the guiding groove is equal to the distance between the guiding rod and the center of the rotating disk.

[0007] Furthermore, a limiting plate is fixedly arranged at the upper end of the guiding rod, and the limiting plate is slidably connected to the upper surface of the connecting plate.

[0008] Furthermore, two groups of "mouth"-shaped support frames are fixedly arranged on the upper part of the base, and both groups of connecting rods are slidably and penetratingly connected to the support frames.

[0009] Furthermore, a push plate is fixedly arranged at the other end of the connecting rod, and a push block is fixedly arranged on the push plate.

[0010] Furthermore, the transmission mechanism also includes a motor, the motor is fixedly arranged at the lower part of the base, and the rotating disk is connected to the motor shaft.

[0011] Furthermore, the fixing mechanism includes a mounting rack and a telescopic rod. The mounting rack is fixedly arranged on the upper part of the base. A sector-shaped groove is formed on the mounting rack, and the groove and the push block have the same axis.

[0012] Further, the telescopic rod is located directly above the groove. The upper end of the telescopic rod is fixedly connected to the mounting bracket, and a pressing plate is fixedly provided at the lower end of the telescopic rod.

[0013] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4As shown in the figure, a gas spring fatigue testing machine proposed by the present utility model includes a base 1, and also includes a transmission mechanism 2 and a fixing mechanism 3. The transmission mechanism 2 is arranged on the base 1. The transmission mechanism 2 includes a rotating disk 202 and a connecting plate 203. The rotating disk 202 is rotatably connected to the upper part of the base 1 and penetrates through the base 1. The connecting plate 203 is slidably connected to the upper part of the rotating disk 202. A guiding rod 204 is fixedly arranged on the rotating disk 202. A guiding groove 205 is formed on the connecting plate 203. The guiding rod 204 and the guiding groove 205 are slidably connected. Connecting rods 207 are fixedly arranged on both sides of the connecting plate 203. The fixing mechanism 3 is fixedly arranged on the upper part of the base 1. The guiding groove 205 is set as an arc-shaped structure. The radius of the guiding groove 205 is equal to the distance between the guiding rod 204 and the center of the rotating disk 202. A limiting plate 206 is fixedly arranged at the upper end of the guiding rod 204. The limiting plate 206 is slidably connected to the upper surface of the connecting plate 203 for limiting the position of the connecting plate 203.

[0023] As Figures 1-4 shown, two sets of U-shaped support frames 101 are fixedly arranged on the upper part of the base 1. Both sets of connecting rods 207 are slidably and penetratingly connected to the support frames 101. A push plate 208 is fixedly arranged at the other end of the connecting rod 207. A push block 209 is fixedly arranged on the push plate 208. The transmission mechanism 2 further includes a motor 201. The motor 201 is fixedly arranged at the lower part of the base 1.

[0024] As Figure 3 shown, the fixing mechanism 3 includes a mounting frame 301 and a telescopic rod 302. The mounting frame 301 is fixedly arranged on the upper part of the base 1. A sector-shaped groove 304 is formed on the mounting frame 301. The groove 304 and the push block 209 have the same axis. The telescopic rod 302 is located directly above the groove 304. The upper end of the telescopic rod 302 is fixedly connected to the mounting frame 301. A pressing plate 303 is fixedly arranged at the lower end of the telescopic rod 302 for mounting and fixing the gas spring to be tested.

The telescopic rod 302 is extended to control the pressing plate 303 to press down to fix one end of the groove 304. The motor 201 is started to rotate the rotating disk 202 and the guiding rod 204. Under the limiting and guiding of the support frame 101, and the sliding cooperation of the guiding rod 204 and the arc-shaped groove-like guiding groove 205, the connecting plate 203 reciprocates between the two support frames 101, and at the same time drives the connecting rods 207, the push plate 208 and the push block 209 on both sides to repeatedly press the gas springs fixed in the two mounting frames 301 on both sides.
