Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model is a corrosion resistance testing device for rebar, including a housing 1; a partition plate 22 is fixedly connected inside the housing 1, and a spray assembly is fixedly connected to the upper surface of the housing 1. A clamping assembly for use with the spray assembly is rotatably arranged inside the housing 1; the spray assembly includes a dual inlet and outlet pump body 3, a water tank 1 4 and a water tank 2 5, the water tank 1 4 and the water tank 2 5 are fixed to the side wall of the housing 1, and each of the opposite sides of the water tank 1 4 and the water tank 2 5 is connected to a connecting pipe 2 8. The two connecting pipes 2 8 are connected to the water inlet end of the dual inlet and outlet pump body 3, and the water outlet end of the dual inlet and outlet pump body 3 is connected to two connecting pipes 1 6. One end of the two connecting pipes 1 6 passes through the housing 1 and extends into the interior, and the ends of the two connecting pipes 1 6 are connected to a nozzle 9.

[0025] The partition plate 22 divides the housing 1 into two independent chambers for simultaneous testing of different properties of the rebar. Connecting to an external power source activates the dual-inlet / outlet pump 3. Water inlets on both sides of the pump 3 extract different testing media from water tank 4 and water tank 5, respectively, and spray them through nozzles 9 into the two chambers inside the housing 1. The rebar surface is clamped by the clamping assembly. After a period of settling, the corrosion of the rebar surface can be tested. The clamping assembly is made of stainless steel and is corrosion-resistant. The media in water tank 4 and water tank 5 can be adjusted according to different testing requirements. For corrosion resistance testing, the testing media are salt water and ordinary water, atomized and sprayed through nozzles 9 to create a saline environment in one chamber and a humid environment in the other.

[0026] Please see Figures 2-5The clamping assembly includes two sets of support seats 12 fixed to the upper surface inside the housing 1. A circular disk 11 is rotatably disposed on the upper surface of the support seat 12. Several guide grooves 13 are opened on the upper surface of the circular disk 11. A clamping block 14 is slidably disposed inside each guide groove 13. A circular rod 17 is fixedly connected to the bottom of the circular disk 11. Several connecting rods 18 are fixedly connected to the outer wall of the circular rod 17. A slider 19 is slidably connected to the outer wall of each connecting rod 18. The end of the clamping block 14 is fixedly connected to the upper surface of the slider 19. A driving assembly is fixedly disposed at the bottom of the circular rod 17. The driving assembly includes a worm gear 20 fixedly disposed at the bottom of the circular rod 17. A circular seat 15 rotating inside the housing 1 is fixedly connected to the bottom of the worm gear 20. A worm 16 is meshed with the outer wall of the worm gear 20. A motor 10 mounted on the housing 1 is fixedly connected to one end of the worm 16.

[0027] Holding the threaded steel bar to be tested, the external power supply is connected to start the motor 10, which drives the worm gear 16 to rotate in the forward direction. The worm gear 16 has two threads on its surface. The motor 10 specifically refers to a servo motor. When the worm gear 16 rotates, the threads at both ends of its surface mesh with two worm wheels 20, thereby driving the two worm wheels 20 inside the housing 1 to rotate. The rotation of the worm wheels 20 drives the circular disk 11 to rotate. The guide groove 13 on the surface of the circular disk 11 guides the clamping block 14 to slide. During the sliding process, the slider 19 at the bottom of the clamping block 14 slides along the connecting rod 18 fixed to the outer wall of the circular rod 17 in a direction that moves closer to each other, so that multiple clamping blocks 14 move closer to each other and retract, realizing that the two sets of clamping components clamp the threaded steel bar synchronously. With the help of two independent chambers, different properties of the threaded steel bar can be tested at the same time.

[0028] Please see Figure 1 The outer wall of the box 1 is hinged with a door 2, and the outer wall of the door 2 is fixedly connected with a handle 21.

[0029] The door 2 prevents the sprayed medium from entering the external environment of the tank, and the dual inlet and outlet pump body 3 makes it easy to open the door 2.

[0030] The operation process of this embodiment is as follows: Holding the threaded steel to be tested, connecting an external power source to start the motor 10 to drive the worm gear 16 to rotate in the forward direction. The worm gear 16 has two threads on its surface. The motor 10 specifically refers to a servo motor. When the worm gear 16 rotates, the threads at both ends of its surface mesh with two worm wheels 20, thereby driving the two worm wheels 20 inside the housing 1 to rotate. The rotation of the worm wheels 20 drives the circular disk 11 to rotate. The guide groove 13 on the surface of the circular disk 11 guides the clamping block 14 to slide. During the sliding process, the slider 19 at the bottom of the clamping block 14 slides along the connecting rod 18 fixed to the outer wall of the circular rod 17 in a direction that brings the multiple clamping blocks 14 closer to each other and retracts, realizing the simultaneous movement of the two sets of clamping components. The threaded steel is clamped, and the external power supply is connected to start the dual inlet and outlet pump body 3. The water inlets on both sides of the dual inlet and outlet pump body 3 extract different test media from the water tank 1 4 and water tank 2 5 respectively, and spray them through the nozzle 9 into the two chambers inside the housing 1. The threaded steel surface is clamped by the clamping assembly. After a period of static time, the corrosion of the threaded steel surface can be tested. The clamping assembly is made of stainless steel and has corrosion resistance. The media in water tank 1 4 and water tank 2 5 can be adjusted according to different test requirements. For corrosion resistance testing, the test media are salt water and ordinary water. The media are atomized and sprayed through the nozzle 9 to create a saline environment in one chamber and a humid environment in the other chamber.
