DETAILED DESCRIPTION

[0022] The utility model makes further detailed description in combination with the drawings below.

[0023] Example one

[0024] To solve the above technical problem, the technical scheme provided by the utility model is: a new material research and development test bench, in combination with the drawings Figures 1-2 It comprises mounting plate 1, the support table part is installed in the corresponding test equipment through mounting plate 1, the device generally presents a bracket structure, is used in the corrosion resistance of new material test, clamps the sample to be detected, and tests in the corrosive liquid, so it needs to be installed roughly above the test liquid container;

[0025] Further in combination with the drawings Figure 4 One end of the mounting plate 1 is rotatably connected with a support column 8, a clamping mechanism for clamping material samples is connected below the support column 8, the clamping mechanism comprises a screw rod 15, the support column 8 comprises an internally threaded cylinder structure, the screw rod 15 penetrates the support column 8 and is connected with the support column 8 through a threaded structure, a handle two 16 for conveniently rotating the screw rod 15 is connected to the top end of the screw rod 15, a support block 17 is connected to the bottom end of the screw rod 15, a V-shaped clamping rod 18 is rotatably connected to the bottom end of the support column 8, a guide rod 19 is connected between the center position of the clamping rod 18 and one side of the support block 17, and a rubber clamping block 20 for abutting on the material sample and increasing the friction effect is installed at the bottom end of the clamping rod 18.

[0026] First, the sample is clamped and inserted into the test liquid with corrosive property to detect the corrosion resistance of the new material under test, the screw rod 15 is rotated by hand holding the handle two 16, the screw rod 15 descends in the support column 8 as a screw cylinder, the position after descending can be fixed through the threaded structure, after the support block 17 at the bottom end of the screw rod 15 descends together with the screw rod 15, the guide rods 19 on both sides will lift the clamping rods 18 to make them away from each other and open, and vice versa, the sample is clamped.

[0027] In combination with the drawings Figures 1-3The mounting plate 1 is equipped with a lifting mechanism that lifts the support column 8 to remove the material sample from the test liquid. The lifting mechanism includes a support shaft 12, which is rotatably connected to the top side of the support column 8. The mounting plate 1 is connected to a support frame 11 that supports the support shaft 12. Both ends of the support shaft 12 extend to the outside of the support frame 11 and are connected to handles 13 for easy hand rotation of the support shaft 12. A sector gear is installed on the support shaft 12. A plurality of discs 10 that cooperate with the sector gear are evenly connected to the top of the support column 8.

[0028] The lifting mechanism is mainly used to lift the sample with corrosive liquid attached from the test solution. By rotating the support shaft 12 by holding the handle 13, the convex teeth on the sector gear on the support shaft 12 are engaged between two adjacent discs 10 on the support column 8. After rotation, the support column 8 carries the sample up and down by turning the discs 10 one by one. The support shaft 12 is connected to the support frame 11 with a certain resistance for rotation. Therefore, the weight of the sample and the support column 8, screw 15 and other components is not enough to make them rotate.

A motor 3 that drives the drive shaft 2 is installed above the mounting plate 1. A first pulley is installed on the drive shaft 2. A second pulley is installed on the bushing 6. A transmission belt 5 is connected between the first pulley and the second pulley to achieve synchronous rotation of the drive shaft 2 and the bushing 6.

[0031] After the motor 3 starts running, the transmission shaft 2 rotates. Under the action of the transmission belt 5 and pulleys between the transmission shaft 2 and the bushing 6, the bushing 6 carries the support column 8 to rotate. The sample immersed in the test solution rotates slowly in the test solution, which can enhance its contact with the test solution and accelerate the corrosive reaction. Combined with the rotation speed of the motor 3, the relevant test results can be calculated, and the waiting time for the corrosion resistance test results is also significantly shortened.
