Technical Field
[0001] This utility model relates to the field of AC power cord production technology, specifically to a salt spray tester for AC power cord production and testing. Background Technology
[0002] AC power cords are key components connecting electrical devices and power sources, responsible for carrying power transmission. During AC power cord production, durability testing is required, necessitating the use of a salt spray test chamber. This chamber simulates marine or industrial salt spray environments to test the corrosion resistance of materials, components, and coatings. However, a small spray area can affect the accuracy of test results. To overcome this limitation, existing technology (application number 202220386377.5, application date 2022-02-02) addresses this issue. (Patent application No. 3) discloses an environmentally friendly salt spray testing machine with controllable salt spray concentration. During use, the test items are fixed on the vibration table assembly, and the items are rotated at multiple angles by a flipping mechanism. When spraying salt water, the items can be sprayed more quickly, and it can meet the requirements of tilt and vibration tests, reducing the test time and improving the flexibility of the testing machine. At the same time, when preparing the salt water, the mass fractions of water and salt are sent from the feeding tank to the mixing tank through a metering pump and thoroughly mixed, ensuring the controllability of the salt water content in the experiment and improving the accuracy of the corrosion resistance test data.
[0003] Meanwhile, during use, liquid needs to be collected to facilitate cleaning of the machine's interior. However, the salt spray test machine in the aforementioned application does not have a structure to prevent liquid residue during use, which makes it inconvenient to collect the liquid quickly, increasing the workload of staff and reducing work efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a salt spray tester for AC power cord production testing, in order to solve the problem mentioned in the background art that the lack of a structure to prevent liquid residue during use leads to inconvenient and rapid collection of liquid, increasing the workload of staff and reducing work efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a salt spray tester for AC power cord production testing, comprising a machine body, a protective cover snapped onto the upper surface of the machine body, a material box disposed on the side of the machine body, an external plate fixedly connected to the left side surface of the machine body, and a drain pipe bolted to the surface of the machine body; a conveying pipe rotatably disposed inside the protective cover, and an automatic spraying plate fixedly connected to the surface of the conveying pipe; a rotating shaft rotatably disposed inside the machine body, a placement plate fixedly connected to the inner wall of the machine body, a movable plate movably disposed on the lower surface of the placement plate, and a striking rod fixedly connected to the upper surface of the movable plate.
[0006] Preferably, a vertical plate is fixedly connected to the upper surface of the outer plate, and a connecting shaft is rotatably provided inside the vertical plate. A motor is bolted to the lower surface of the outer plate, and bevel gears are fixedly connected to the output end of the motor and the left side of the connecting shaft.
[0007] Preferably, a circular plate is fixedly connected to the right side of the connecting shaft, and a protrusion is fixedly connected to the surface of the circular plate. An outer frame is sleeved on the surface of the protrusion, and a lower connecting rod is fixedly connected to the lower surface of the outer frame.
[0008] Preferably, the lower connecting rod passes through the interior of the outer connecting plate, and a rack is fixedly connected to the upper surface of the outer connecting frame, with the rack symmetrically distributed on both sides of the outer connecting frame.
[0009] Preferably, the conveying pipe is connected to the material box via an external flexible hose, and a working gear that meshes with a rack is fixedly connected to the end of the conveying pipe.
[0010] Preferably, the connecting shaft and the rotating shaft are connected by a pulley, and a lever is fixedly connected to the end of the rotating shaft, with the levers symmetrically distributed on both sides of the rotating shaft.
[0011] Preferably, a limiting post is fixedly connected to the lower surface of the placement plate, and the movable plate is sleeved on the surface of the limiting post. The end of the limiting post is protruding, and a return spring is fixedly connected between the limiting post and the movable plate.
[0012] Preferably, the striking rods are evenly distributed on the upper surface of the movable plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This salt spray tester for AC power cord production testing adopts a novel structural design, the specific details of which are as follows: (1) In the process of using the salt spray tester for AC power cord production testing, the material to be tested is placed on the placement plate, and then the protective cover is clamped on the machine body. After the motor is started, the motor drives the connecting shaft to rotate through the bevel gear. At this time, the outer frame drives the rack to make reciprocating linear motion in the vertical direction under the action of the round plate, the protrusion and the lower connecting rod. At this time, the rack cooperates with the working gear, so that the conveying pipe reciprocates inside the protective cover. At this time, the working range of the automatic spray plate increases, the flexibility is improved, and the test results are more accurate.
[0014] Furthermore, the delivery pipes and automatic spray plates are symmetrically distributed on both sides of the protective cover, which improves the working efficiency of the automatic spray plates.
[0015] (2) When the connecting shaft rotates, the connecting shaft drives the rotating shaft to rotate through the pulley. When the rotating shaft rotates, it will intermittently push the movable plate through the toggle block, so that the movable plate will make reciprocating linear motion in the vertical direction under the action of the thrust, the limit column and the return spring. At this time, the movable plate will intermittently hit the placement plate through the striking rod, so that the liquid remaining on the upper surface of the placement plate will flow down, making it easier for the liquid to be collected by the staff.
[0016] Furthermore, the striking rods are evenly distributed on the upper surface of the movable plate, which optimizes the striking effect.
[0017] (3) The protrusion on the lower surface of the limit column of the salt spray tester for AC power cord production testing limits the movement distance of the movable plate and improves stability. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides the following technical solution: a salt spray tester for AC power cord production testing.
[0022] Example 1: By using an automatically spraying plate 17 that can swing, the spraying range is expanded, ensuring the accuracy of the test results. Figures 1-4 As shown, the machine includes a body 1, a protective cover 2 is snapped onto the upper surface of the body 1, a material box 4 is provided on the side of the body 1, an external plate 6 is fixedly connected to the left side surface of the body 1, and a drain pipe 5 is bolted to the surface of the body 1; a conveying pipe 15 is rotatably installed inside the protective cover 2, and an automatic spraying plate 17 is fixedly connected to the surface of the conveying pipe 15; a vertical plate 8 is fixedly connected to the upper surface of the external plate 6, a connecting shaft 9 is rotatably installed inside the vertical plate 8, a motor 7 is bolted to the lower surface of the external plate 6, and a bevel gear 10 is fixedly connected to the output end of the motor 7 and the left side of the connecting shaft 9.
[0023] A circular plate 11 is fixedly connected to the right side of the connecting shaft 9, and a protrusion 12 is fixedly connected to the surface of the circular plate 11. An outer frame 18 is sleeved on the surface of the protrusion 12, and a lower connecting rod 13 is fixedly connected to the lower surface of the outer frame 18.
[0024] The lower connecting rod 13 passes through the interior of the outer connecting plate 6. A rack 14 is fixedly connected to the upper surface of the outer frame 18, and the rack 14 is symmetrically distributed on both sides of the outer frame 18. The conveying pipe 15 is connected to the material box 4 through the external hose, and a working gear 16 that meshes with the rack 14 is fixedly connected to the end of the conveying pipe 15.
[0025] During use, the AC power cord to be tested is placed on the placement plate 3, and then the protective cover 2 is clipped onto the machine body 1. After starting the motor 7 on the lower surface of the external plate 6, the motor 7 drives the connecting shaft 9 to rotate inside the vertical plate 8 through the bevel gear 10. At this time, the external frame 18, under the action of the circular plate 11, the protrusion 12 and the lower connecting rod 13, drives the rack 14 to make reciprocating linear motion in the vertical direction. At this time, the rack 14 cooperates with the working gear 16 to make the conveying pipe 15 reciprocate inside the protective cover 2. At this time, the working range of the automatic spraying plate 17 increases, improving flexibility and making the test results more accurate. The material box 4 supplies material to the conveying pipe 15 and the automatic spraying plate 17.
[0026] Example 2: Unlike Example 1, the placement plate 3 is slightly vibrated by the tapping rod 22, ensuring no material remains on the placement plate 3. Figures 4-6 As shown, a rotating shaft 19 is provided inside the body 1 for rotation, and a placement plate 3 is fixedly connected to the inner wall of the body 1. A movable plate 21 is movably provided on the lower surface of the placement plate 3, and a striking rod 22 is fixedly connected to the upper surface of the movable plate 21.
[0027] The connecting shaft 9 and the rotating shaft 19 are connected by a pulley, and the end of the rotating shaft 19 is fixedly connected to a lever 20, which is symmetrically distributed on both sides of the rotating shaft 19.
[0028] A limiting post 23 is fixedly connected to the lower surface of the placement plate 3, and a movable plate 21 is sleeved and connected to the surface of the limiting post 23. The end of the limiting post 23 is protruding, and a return spring 24 is fixedly connected between the limiting post 23 and the movable plate 21. The striking rods 22 are evenly distributed on the upper surface of the movable plate 21.
[0029] When the connecting shaft 9 rotates, it drives the rotating shaft 19 to rotate inside the machine body 1 via the pulley. When the rotating shaft 19 rotates, it will intermittently push the movable plate 21 through the toggle block 20. When the movable plate 21 is pushed, it slides on the surface of the limiting post 23. At the same time, the movable plate 21 will squeeze the return spring 24. When the movable plate 21 is not pushed, it rises under the action of the return spring 24. Repeat the above process. Under the action of the thrust, the limiting post 23 and the return spring 24, the movable plate 21 makes a reciprocating linear motion in the vertical direction. At this time, the movable plate 21 will intermittently strike the placement plate 3 through the striking rod 22, causing the liquid remaining on the upper surface of the placement plate 3 to flow down, making it easier for the liquid to be collected by the staff. When it is necessary to remove the AC power cord, the protective cover 2 can be removed. At this time, the power cord on the placement plate 3 can be removed. The operation process is simple and convenient.
[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
