[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely applied. Screws are one of the most common fasteners. After the production of screws, it is necessary to test their salt spray resistance to avoid the trouble that the wall switch is difficult to remove due to rust after long-term use. The salt spray test machine is a test method specifically for detecting the corrosion resistance of various material surfaces.

[0003] Currently, there is no salt spray testing device required for screw production. When the traditional smoke machine is testing, the product is placed on the grid plate inside the box. However, due to the structure of the screw, it is easy to fall out of the grid or get stuck in the grid holes when placed on the grid plate, which is inconvenient to use.

An inner enclosure is detachably installed at the center inside the test chamber, and a bottom plate is detachably installed at the bottom of the test chamber. The inner enclosure, in cooperation with the bottom plate and the inner wall of the test chamber, forms a reservoir for storing brine. A cross plate is detachably installed on one side of the top of the test chamber, and a water absorption rod is detachably installed in the middle of the cross plate. The bottom of the water absorption rod is connected to a salt spray generator, and the end of the salt spray generator extends to the bottom of the reservoir. An electric lifting rod is installed at each of the four corners inside the inner enclosure. The tops of the four electric lifting rods are fixedly connected to a loading platform. A plurality of material holes arranged in a rectangular array are formed on the surface of the loading platform, and a plurality of ventilation holes staggered with the material holes are formed on the surface of the loading platform. A centrifugal induced draft fan is detachably installed at a position near the bottom inside the inner enclosure.

[0006] Further, the bottom surface of the bottom plate and the bottom surface of the test chamber form an independent cavity, and a heating pipe is arranged inside the cavity.

[0007] Further, hydraulic rods are hinged to the middle of both sides of the test chamber, and the piston ends of the hydraulic rods are hinged to both sides of the box cover.

[0008] Further, the box cover has a conical structure and is made of transparent plastic.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following elaborates on the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0018] The present utility model provides a fastener salt spray test device, as Figures 1-3As shown in the figure, it includes a test chamber 1, a control box 2, and a lid 3 hinged to the top of the test chamber 1. The control box 2 is used to be electrically connected to various electrical components to control their on / off and set programs. An inner enclosure 4 is detachably installed at the center inside the test chamber 1, and a bottom plate 6 is detachably installed at the bottom of the test chamber 1. The inner enclosure 4, the bottom plate 6, and the inner wall of the test chamber 1 cooperate to form a reservoir 5 for storing brine. A cross plate 7 is detachably installed on one side of the top of the test chamber 1, a water absorption rod 8 is detachably installed in the middle of the cross plate 7, a salt fog generator 9 is connected to the bottom of the water absorption rod 8, and the end of the salt fog generator 9 extends to the bottom of the reservoir 5. An electric lifting rod 10 is installed at each of the four corners inside the inner enclosure 4. The tops of the four electric lifting rods 10 are fixedly connected to a loading platform 11. A number of material holes 111 arranged in a rectangular array are formed on the surface of the loading platform 11, and a number of ventilation holes 112 staggered with the material holes 111 are formed on the surface of the loading platform 11. A centrifugal induced draft fan 12 is detachably installed at a position near the bottom inside the inner enclosure 4. By setting the loading platform 11 to carry the screws and using the material holes 111 formed thereon, each screw to be tested stands independently, avoiding the situation of screw dropping or jamming, which is convenient to use. At the same time, a centrifugal induced draft fan 12 is arranged at the low end inside the inner enclosure 4 to attract the salt fog, so that the salt fog passes through the ventilation holes 112 formed on the loading platform 11 and fully contacts the surface of the screws, thereby improving the test effect of the screws.

[0019] Specifically, as Figure 2 shown, an independent cavity is formed between the bottom surface of the bottom plate 6 and the bottom surface of the test chamber 1, and a heating pipe 15 is arranged inside the cavity. The brine liquid is heated by the arranged heating pipe 15 to facilitate adjusting the environmental temperature of the salt fog test and improve the practicability of the test device.

[0020] Specifically, as Figure 1 shown, hydraulic rods 14 are hinged to the middle parts of both sides of the test chamber 1. The piston ends of the hydraulic rods 14 are hinged to both sides of the lid 3. The two hydraulic rods 14 can automatically start, open or close the lid 3, and the user does not need to operate manually, improving the degree of automation and reducing the labor intensity.

[0021] Specifically, as Figure 1 shown, the lid 3 has a conical structure and is made of transparent plastic, which is convenient for observing the products during the test.

[0022] Specifically, as Figure 2 shown, an exhaust pipe 13 is inserted into the back of the inner enclosure 4, and the other end of the exhaust pipe 13 penetrates through the test chamber 1 and extends outside the test chamber 1. The exhaust pipe is used to exhaust the salt fog concentrated and attracted into the inner enclosure 4, and the exhaust pipe 13 can be connected to external waste gas treatment equipment to avoid environmental pollution.

[0023] Specifically, as Figure 2 shown, the bottom plate 6 is made of a heat-conducting metal material, and both sides of the bottom plate 6 are coated with an insulating coating. The heat-conducting material can be copper metal, aluminum metal, copper alloy metal, aluminum alloy metal, etc. Adding an insulating coating reduces the leakage of the heat-conducting metal.

[0024] The working principle of the present utility model: The screw sampling products to be tested are respectively inserted into the material holes 111 opened in the loading platform 11, and then the box cover 3 is closed by the hydraulic rod 14. At this time, the salt spray generator 9 is started through the control box 2. The salt spray generator 9 absorbs the brine stored inside the water storage tank 5 through the water absorption rod 8, and then performs atomization treatment. At this time, the centrifugal induced draft fan 12 is started to attract the salt spray, so that the salt spray passes through the air holes 112 opened in the loading platform 11 and fully contacts the surface of the screw, thereby improving the test effect of the screw.
