[0002] Salt spray test is an environmental test that mainly uses artificial simulated salt spray environment conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is natural environment exposure test, and the other is artificial accelerated simulated salt spray environment test.

[0003] After searching, for example, a utility model patent with Chinese patent publication number CN217111993U discloses a device for detecting the corrosion resistance of galvanized welded mesh. The utility model cooperates a sliding rod, a sliding sleeve, a guide rail, a slider, a hook rod, a hanging rope and a gravity block, so that four hook rods can hook the four corners of the galvanized welded mesh respectively. Under the action of the four gravity blocks, the galvanized welded mesh can be flattened.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 In this embodiment, a salt spray corrosion resistance detection device includes a box body 1, a box cover 2 is arranged on the top of the box body 1, and sealing strips are provided at the installation positions of the box cover 2 and the box body 1 to prevent salt spray leakage from polluting the environment. A mounting block 3 is fixedly installed on the inner wall of the box body 1, and the mounting block 3 mainly plays the role of bearing and installation. An operating table 4 is arranged on the right side of the box body 1, and a working mechanism 5 is arranged inside the box body 1;

[0023] The working mechanism 5 includes a load-bearing rod 501, and the load-bearing rod 501 is fixedly installed on the inner wall of the box body 1. Two guide sleeves 502 are slidably installed on the surface of the load-bearing rod 501, and a fixed block 503 is fixedly installed on the surface of the guide sleeve 502. A stabilizing seat 504 is fixedly installed on the top of the fixed block 503, and a fixed rod 505 is slidably installed inside the stabilizing seat 504. The fixed rod 505 can be engaged with the matching groove 508 under the reaction force of the spring 507, so as to realize the unilateral limit fixing of the mesh material. A limiting block 506 is arranged on the surface of the fixed rod 505, and a spring 507 is wound around the surface of the fixed rod 505. A matching groove 508 is provided on the surface of the fixed block 503, and a mounting seat 509 is fixedly installed on the surface of the fixed block 503. There are two mounting seats 509 in this device, and a threaded rod 511 is rotatably installed in one of the mounting seats 509, which mainly plays the role of fixing and limiting, and a pressure rod 513 is slidably installed in the other mounting seat 509, which mainly plays the role of guiding and limiting. A motor 510 is fixedly mounted on the surface of the mounting seat 509, a threaded rod 511 is fixedly mounted at the output end of the motor 510, a traveling block 512 is threadedly connected on the surface of the threaded rod 511, a pressure rod 513 is fixedly mounted on the surface of the traveling block 512, a spray head 514 is fixedly mounted on the surface of the mounting block 3, and the spray head 514 is connected to one side of the liquid storage tank through a rubber tube. At the beginning of the experiment, the copper acetate salt solution flows to the spray head 514 through the rubber tube under the pressure of the external pump body. A purification device 515 is arranged inside the mounting block 3, and the purification device 515 includes a filter screen, a fan, a sealing tube, and a liquid storage tank. Since the copper acetate salt spray is mildly toxic, at the end of the detection test, the salt mist in the box body 1 and the box cover 2 needs to be negatively pressured and absorbed by the fan to prevent the salt mist from being discharged to the outside world and polluting the environment when the box cover 2 is opened, thereby ensuring the health and safety of the experimenters. A storage plate 516 is fixedly mounted on the inner wall of the box body 1, and the surface of the storage plate 516 is a mesh structure to facilitate the salt mist to flow to the surface of the mesh material.

[0024] When implementing, follow these steps:

[0025] 1) First, place the curled mesh material on the top of the storage plate 516, pull up the fixing rod 505, and insert the fixing rod 505 into the pores of the mesh material;

[0026] 2) Then, the fixing rod 505 is matched with the matching groove 508 by the elastic reaction force of the spring 507, so that the single-side limit of the mesh material is fixed, and at this time, the pressing rod 513 is located above the bent mesh material;

[0027] 3) The motor 510 is restarted, and the travel block 512 pulls the pressure rod 513 to move horizontally under the spiral transmission, so as to lay the curled web material flat;

[0028] 4) Finally, copper acetate salt water spray is introduced for detection.

[0029] In summary, the salt spray corrosion resistance detection device is provided with a working mechanism 5 inside the box body 1, and the welded mesh is laid flat by a single-sided limit fixation and a pressure rod 513. The device uses a fixed rod 505 and a matching groove 508 to achieve single-sided plug-in limit on the welded mesh, and drives the threaded rod 511 to rotate through a motor 510, so that the pressure rod 513 lays the curled mesh material flat under the traction of the traveling block 512, and cooperates with the storage plate 516 to limit the laid mesh material to prevent it from falling off and curling again.
