[0023] 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.

[0024] The utility model provides a salt spray corrosion test box, including a box body 1. In some embodiments of the present application, the signal of the box body 1 is ESR798-E. The working principle of the box body 1 is the prior art and is not described in detail here. A sample rack is evenly fixed in the inner cavity of the box body 1. The sample rack includes a hydraulic telescopic rod 14 fixedly connected to the bottom of the inner cavity of the box body 1. The top of the hydraulic telescopic rod 14 is fixedly connected to a connecting rod 12. The outer side of the connecting rod 12 is fixed with a sample placement plate 11 and a hanging rod 13. Holes are evenly arranged on the sample placement plate 11. When the smoke corrosion test box is in use, the automobile parts to be tested are placed on the sample placement plate 11 or hung on the hanging rod 13. The extension and retraction of the hydraulic telescopic rod 14 can change the position of the connecting rod 12 fixedly connected thereto. When the connecting rod 12 moves, the positions of the sample placement plate 11 and the hanging rod 13 fixed to the connecting rod 12 also change, which is convenient for taking and placing samples.

[0025] A positioning plate 15 is fixed to the bottom end of the connecting rod 12, and the positioning plate 15 contacts the inner wall of the box body 1. The positioning plate 15 can be used to position the sample rack so that it can move in the vertical direction. A receiving groove is provided in the middle of the bottom end of the connecting rod 12, and the hydraulic telescopic rod 14 is located in the inner cavity of the receiving groove. The bottom of the hydraulic telescopic rod 14 is fixedly connected to the bottom of the inner cavity of the box body 1, and the top of the hydraulic telescopic rod 14 is fixedly connected to the top of the inner cavity of the receiving groove. Through the setting of the receiving groove, the hydraulic telescopic rod 14 can be hidden in the connecting rod 12, reducing the influence of salt spray on the hydraulic telescopic rod 14 when the test box is used, and extending the service life of the hydraulic telescopic rod 14.

[0026] In some embodiments of the present application, the outer surface of the sample holder is wrapped with an isolation pad, the material of the isolation pad may be rubber, and the isolation pad is used to isolate the sample holder from salt spray, thereby extending the service life of the sample holder.

[0027] The top of the sample rack is provided with an illumination lamp 22. By providing the illumination lamp 22, the brightness around the sample rack can be increased, making it convenient for the staff to observe the corrosion of the sample.

[0028] An opening and closing window is provided between two adjacent sample racks, and the opening and closing window includes a plurality of blades 17 movably connected to the inner cavity of the box body 1 and a power chamber 4 fixed to the box body 1. An active rod 18 is fixed to the middle of one end of the blade 17, and the other end of the active rod 18 extends into the inner cavity of the power chamber 4, and the active rod 18 is movably connected to the power chamber 4, and the other end of the active rod 18 is fixedly connected to a gear 19, and a gear plate 20 is connected to the inner cavity of the power chamber 4 through a hydraulic telescopic rod 21, and the gear plate 20 is meshed with the gear 19, and a driven rod is movably connected to the middle of the other end of the blade 17, and the driven rod is movably connected to the inner wall of the box body 1. By setting the active rod 18 and the driven rod, the fan blade 17 is in a state of active connection with the box body 1. By setting the hydraulic telescopic rod 21, the extension and retraction of the hydraulic telescopic rod 21 can change the position of the toothed plate 20 fixedly connected thereto. The toothed plate 20 can drive the gear 19 meshing therewith to rotate when moving. The gear 19 can drive the fan blade 17 to rotate through the active rod 18 fixedly connected thereto. When the fan blade 17 is in a vertical state, two adjacent fan blades 17 are in a contact state, the top of the opening and closing window contacts the top of the inner cavity of the box body 1, and the bottom of the opening and closing window contacts the bottom of the inner cavity of the box body 1. At this time, two adjacent sample racks are separated by the opening and closing window. The inner cavity of the box body 1 can be divided into multiple independent test cavities by the opening and closing window, which is convenient for taking and placing samples in the test cavity. When the fan blade 17 is in a non-vertical state, the inner cavity of the test cavity separated by the opening and closing window can be in a connected state, which is convenient for salt spray to flow in the test box.

[0029] The outer surface of the fan blade 17 is wrapped with a sealing gasket, which may be made of rubber. The setting of the sealing gasket can reduce the impact of salt spray on the fan blade 17 and extend the service life of the fan blade 17. The distance between two adjacent active rods 18 is the same as the width of the fan blade 17. When the fan blade 17 is in a vertical state, the two adjacent fan blades 17 may be in contact.

[0030] A sealing cover 2 is movably connected to the top of the box body 1, and grooves 5 are evenly arranged at the bottom of the sealing cover 2. A sealing plate 7 is clamped in the inner cavity of the groove 5. The number of sealing plates 7 is the same as the number of sample racks. One end of the sealing plate 7 and one end of the sealing cover 2 are both provided with observation windows 9, and the end of the sealing cover 2 away from the observation window 9 is movably connected to the box body 1 through a round rod. A servo motor is fixed to the outside of the box body 1, and the end of the output shaft of the servo motor is fixedly connected to the end of a round rod. The round rod is movably connected to the box body 1, and the other end of the round rod is fixedly connected to the sealing cover 2. Through the setting of the servo motor 24, the rotation of the servo motor 24 can drive the sealing cover 2 to rotate, thereby realizing the electric opening and closing of the sealing cover 2, that is, the sealing cover 2 is driven by the servo motor 24.

[0031] Electromagnets 1 8 are fixed to both ends of the sealing plate 7, electromagnets 2 6 matched with electromagnets 1 8 are fixed to both ends of the groove 5, and electromagnets 3 10 matched with electromagnets 1 8 are provided on the top of the box body 1. When electromagnets 1 8 and electromagnets 2 6 are both in a powered-on state and the same current is passed through, electromagnets 1 8 and electromagnets 2 6 are magnetically attracted to each other. At this time, the sealing plate 7 and the sealing cover 2 can be fixed together. When the sealing cover 2 moves, the sealing plate 7 can move with the sealing cover 2. When electromagnets 1 8 and electromagnets 3 10 are both in a powered-on state and the same current is passed through, the sealing plate 7 is fixedly connected to the top of the box body 1. When the sealing cover 2 moves, the sealing plate 7 and the sealing cover 2 can be separated. The sealing plate 7 can seal the test cavity to facilitate the placement of some test samples.

[0032] In some embodiments of the present application, the models of electromagnet 1 8 , electromagnet 2 6 and electromagnet 3 10 are all XDA-50 / 42.

[0033] A temperature and humidity sensor 16 and an atomizing nozzle 23 are provided on the inner wall of the box. Two adjacent temperature and humidity sensors 16 or atomizing nozzles 23 at the same height are separated by an opening and closing window. Through the setting of the atomizing nozzle 23, salt mist can be evenly sprayed on the sample. The temperature and humidity sensor 16 can detect the temperature and humidity around the sample. The working principles of both the atomizing nozzle 23 and the temperature and humidity sensor 16 are existing technologies and will not be elaborated here.

[0034] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0035] In summary: when the salt spray corrosion test box is used, when placing the automobile parts to be tested, the hydraulic telescopic rod 14 is extended, and the extension of the hydraulic telescopic rod 14 causes the sample rack to move up until the sample placement plate 11 or the hanging rod 13 at the bottom of the sample rack moves to the outside of the box body 1. The staff can place the automobile parts to be tested on the sample placement plate 11 at the bottom of the sample rack or hang them on the hanging rod 13. After the sample placement plate 11 or the hanging rod 13 at the bottom of the sample rack are full of parts, the hydraulic telescopic rod 14 is retracted until another sample placement plate 11 or the hanging rod 13 moves to the top of the box body 1. The staff can continue to place parts. After the sample rack is full of parts, the hydraulic telescopic rod 14 is retracted to the maximum. The sample rack is moved into the inner cavity of the box body 1, and the sealing cover 2 is closed. The box body 1 can be operated so that the sample is surrounded by salt mist. If all the samples in the box body 1 need to be taken out, the electromagnet 1 8 and the electromagnet 2 6 are energized, and the sealing plate 7 and the sealing cover 2 are fixed. When the sealing cover 2 is opened, the sealing plate 7 moves accordingly. When the staff takes the sample, the opposite order is adopted: the hydraulic telescopic rod 14 is extended, and the extension of the hydraulic telescopic rod 14 exposes the top of the sample rack. After the samples at the top of the sample rack are taken out, the hydraulic telescopic rod 14 continues to extend, and the staff can continue to take parts, thereby reducing the working distance of the employees and improving the efficiency of sample taking and placing. If only the sample in a certain test chamber needs to be taken out, the opening and closing window works, and the hydraulic telescopic rod 21 drives the toothed plate 20 fixedly connected thereto to move. When the toothed plate 20 moves, it drives the gear 19 meshing therewith to rotate, and the gear 19 drives the fan blade 17 to rotate through the active rod 18 fixedly connected thereto, until the fan blade 17 is in a vertical state. At this time, the opening and closing window separates a certain test chamber from its adjacent test chamber, and the electromagnet 1 8 and the electromagnet 2 6 placed on a certain test chamber are in an energized state, and the electromagnet 1 8 and the electromagnet 3 10 above the remaining test chambers are in an energized state. After the sealing cover 2 is opened, a certain test chamber is in an open state, and the remaining test chambers are sealed by the sealing plate 7 above it. The placement and removal of samples in a certain test chamber will not affect the continued testing of samples in other test chambers.

[0036] The standard parts used in the utility model can be purchased from the market, and the special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
