Description

Technical Field

[0001] This utility model relates to the technical field of salt spray test chambers, and specifically to a salt spray test chamber. Background Technology

[0002] The salt spray test chamber exposes samples to highly corrosive conditions for a short period of time by continuously spraying salt spray, allowing for rapid observation of their corrosion resistance. Compared to natural environment exposure tests, this method significantly shortens the time to obtain results. The sample is placed in a sealed chamber, and sodium chloride solution is atomized to create a salt spray environment that simulates the ocean or a salty and humid climate, thus enabling the testing of the sample's corrosion resistance. The salt spray test chamber consists of a chamber, a spray system, a collection device, a heating system, a control system, and a pressure detection system. The operator places the sample inside the collection device for retention and then places the entire collection device inside the chamber to conduct the salt spray test.

[0003] CN212932333U discloses a salt spray test chamber, including a chamber body. An atomizing nozzle is installed inside the chamber. The atomizing nozzle is connected to a high-pressure water pipe via a connecting cylinder. One end of the connecting cylinder connected to the atomizing nozzle has a through hole. The end of the atomizing nozzle facing the connecting cylinder has a spherical protrusion. A limiting ring is coaxially fixed inside the connecting cylinder. The spherical protrusion is located inside the connecting cylinder and seamlessly abuts against the inner wall of the central hole of the limiting ring and the inner wall of the through hole. A water passage hole is provided inside the spherical protrusion. One end of the water passage hole communicates with the central hole of the limiting ring, and the other end communicates with the interior of the atomizing nozzle. This application solves the problem of salt spray not being able to uniformly cover the surface of the tested object.

[0004] While the existing technology CN212932333U has many advantages in use, it still has the following problems: its testing efficiency for samples is not perfect. Due to the stable storage space inside the chamber, when testing small-sized samples, it is still necessary to fill the entire chamber with atomized sodium chloride solution, resulting in low coverage efficiency of sodium chloride solution and poor adaptability to testing samples of different sizes. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a salt spray test chamber.

[0006] The technical solution adopted by this utility model to solve its technical problem is a salt spray test chamber, including a chamber body, a support frame and a support plate. A transparent cover plate is rotatably connected to the upper outer wall of the chamber body. A support frame is set inside the chamber body. Slider blocks are installed on both outer walls of the support frame. A support plate is set at the upper end of the support frame. A screw is rotatably installed on one side of the upper outer wall of the support frame.

[0007] By adopting the above technical solution, staff can observe the testing process of samples inside the chamber through the transparent cover. After the staff opens the latch, the transparent cover is hinged to the chamber, allowing it to rotate circumferentially, thus freeing the chamber from the cover and exposing the internal testing cavity. Furthermore, the spring force pushes the slider, support frame, and support plate vertically upwards, causing the support plate to protrude from the testing cavity carrying the tray. This facilitates the staff's easy access to and from the samples placed inside the tray, ensuring smooth and efficient sample handling. When the operator manually rotates the screw, it can be driven to move vertically through the screw hole inside the support plate, adjusting the distance between the support plate and the support frame. This allows for adjustment of the distance between the support plate and the upper part of the detection chamber after the support plate moves back to the lower end of the chamber, ensuring that the adjusted distance matches the sample size. Furthermore, based on the position of the support plate inside the chamber, the detection chamber space inside the chamber can be adjusted to ensure that the detection chamber range matches the sample size, thereby improving the sodium chloride solution coverage efficiency and enhancing the equipment's adaptability to testing samples of different sizes.

[0008] Specifically, the outer walls of both sides of the box are equipped with buckles, which are snapped together with the outer wall of the transparent cover. A handle is installed on one side of the outer wall of the transparent cover, a control module is provided on one side of the outer wall of the box, and equal-spaced parallel air inlets are opened on one side of the inner wall of the box.

[0009] By adopting the above technical solution, the transparent cover can rotate with the chamber via a hinge, thus covering the top of the chamber. This allows users to easily open and close the test chamber, and during the test, the test conditions inside the chamber can be directly observed through the transparent cover without frequently opening the cover, reducing interference from external factors. Operators can rotate the cover by the handle, and the operator control module can precisely control parameters such as temperature, humidity, and spraying time of the test chamber, ensuring that the test environment inside the chamber is controlled. Furthermore, the atomizing device used with the test chamber can input the atomized sodium chloride solution into the air inlet and deliver it evenly to the detection chamber inside the chamber.

[0010] Specifically, the inner wall of the box has grooves on both sides, the slider is slidably installed inside the grooves, a spring seat is installed at the lower end of the inner wall of the groove, a support spring is installed inside the spring seat, the upper end of the support spring contacts the lower outer wall of the slider, and the slider is elastically connected to the inner wall of the groove through the support spring.

[0011] By adopting the above technical solution, the support spring achieves the purpose of supporting the slider and the support frame. After the transparent cover plate is released from the buckle and flipped, the spring force can push the slider and the support frame to move upward, maintaining the position of the support plate, which makes it convenient for staff to pick up and put down the sample. After the transparent cover plate flips and resets, the driving force of the linkage rod on the support plate drives the support plate and the support frame to move downward and reset. At this time, the slider compresses and stores energy in the support spring.

[0012] Specifically, a sealing gasket for providing a seal is bonded and fixed to the outer wall of the support plate, and the sealing gasket is in contact with the inner wall of the box.

[0013] By adopting the above technical solution, the sealing gasket enhances the sealing between the support plate and the inner wall of the chamber, preventing salt spray from leaking from the gap between the support plate and the chamber, and ensuring the stability of the test environment.

[0014] Specifically, the outer wall of the support plate has through holes arranged in a rectangular array, and the upper outer wall of the support frame is screwed with guide rods arranged in a rectangular array. The size of the guide rods is smaller than the inner wall size of the through holes, and the guide rods are movably installed inside the through holes.

[0015] By adopting the above technical solution, the guide rod and through hole play a guiding role when the support plate moves up and down, ensuring that the support plate can move smoothly.

[0016] Specifically, the support plate has a screw hole inside that is adapted to the screw rod, and the screw rod is threaded into the screw hole. Both sides of the upper outer wall of the support plate are screwed with a storage tray.

[0017] By adopting the above technical solution, staff can place samples in two separate baskets, enabling the differentiation of different types of samples. Furthermore, through the screw hole and screw thread connection, staff can precisely adjust the height of the support plate by rotating the screw, thus satisfying the adjustment of the internal range of the detection chamber inside the box.

[0018] Specifically, sleeves are installed on both sides of the inner wall of the transparent cover and both sides of the outer wall of the upper end of the support plate, and a linkage rod is connected to the inside of the sleeve by a pin.

[0019] By adopting the above technical solution, when the transparent cover is opened or closed, the linkage rod will drive the support plate to move together, realizing the linkage opening and closing of the transparent cover and the support plate. When the support plate moves up, the linkage rod can push the transparent cover to flip open. When the staff flips the transparent cover back to its original position, the transparent cover drives the support plate to move down and back to its original position through the clip and the linkage rod, ensuring that the movement of the support plate and the transparent cover is coordinated and consistent.

[0020] The beneficial effects of this utility model are: The salt spray test chamber described in this utility model allows the support plate carrying the storage tray to protrude out of the test cavity, making it convenient for staff to pick up and put down the samples placed inside the storage tray, ensuring the smoothness and efficiency of sample handling.

[0021] The salt spray test chamber described in this utility model can adjust the detection chamber space inside the chamber by adjusting the position of the support plate inside the chamber, ensuring that the range of the detection chamber is adapted to the size of the sample, thereby improving the coverage efficiency of sodium chloride solution and enhancing the adaptability of the equipment to testing samples of different sizes.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the salt spray test chamber of this utility model includes a chamber body 1, a support frame 2, and a support plate 3. A transparent cover plate 11 is rotatably connected to the upper outer wall of the chamber body 1. The support frame 2 is installed inside the chamber body 1. Slider blocks 22 are installed on both outer walls of the support frame 2. The support plate 3 is installed at the upper end of the support frame 2. A screw 23 is rotatably installed on one side of the upper outer wall of the support frame 2. The screw 23 and the support frame 2 are connected by a bearing seat containing a deep groove ball bearing. The bearing seat is screwed to the upper outer wall of the support frame 2. The screw 23 is interference-fitted into the inner ring of the deep groove ball bearing, and the screw 23 is rotatably connected to the support frame 2 through the deep groove ball bearing inside the bearing seat.

[0027] During use, staff can observe the testing process of samples inside the chamber 1 through the transparent cover 11. After the staff opens the buckle 12, the transparent cover 11 is hinged to the chamber 1, allowing the transparent cover 11 to rotate circumferentially, thus freeing the chamber 1 from the cover and exposing the testing chamber inside. The elastic force of the support spring 16 pushes the slider 22, support frame 2, and support plate 3 to move vertically upwards, causing the support plate 3 to carry the tray 32 out of the testing chamber. This facilitates the staff's loading and unloading of samples placed inside the tray 32, ensuring smooth and efficient sample handling. Furthermore, when the operator manually rotates the screw 23, it can be driven to move vertically through the screw hole inside the support plate 3, adjusting the distance between the support plate 3 and the support frame 2. This allows for adjustment of the distance between the support plate 3 and the upper part of the detection chamber after the support plate 3 is moved back to the lower end of the chamber 1, ensuring that the adjusted distance matches the size of the sample. Based on the position of the support plate 3 inside the chamber 1, the space of the detection chamber inside the chamber 1 can be adjusted to ensure that the range of the detection chamber matches the size of the sample, thereby improving the coverage efficiency of the sodium chloride solution and enhancing the equipment's adaptability to testing samples of different sizes.

[0028] To maintain the position of the transparent cover 11 in use, for example, as shown... Figure 1 As shown, buckles 12 are installed on both outer walls of the box 1, and the buckles 12 are snapped together with the outer wall of the transparent cover 11. A handle is installed on one outer wall of the transparent cover 11, and a control module 13 is provided on one outer wall of the box 1. An air inlet 14 is provided on one inner wall of the box 1.

[0029] During use, the transparent cover 11 can rotate with the chamber 1 via a hinge, allowing the transparent cover 11 to cover the top of the chamber 1. This enables users to easily open and close the test chamber. During the test, the test conditions inside the chamber can be directly observed through the transparent cover 11 without frequently opening the cover, reducing interference from external factors. The operator can rotate the cover by the handle, and the operator control module 13 can precisely control parameters such as temperature, humidity, and spraying time of the test chamber, ensuring that the test environment inside the chamber 1 is controlled. The atomizing device used with the test chamber can input the atomized sodium chloride solution into the air inlet 14 and deliver it evenly to the detection chamber inside the chamber 1 through the air inlet 14.

[0030] To limit the movement trajectory, for example, such as Figure 3 As shown, both sides of the inner wall of the box 1 are provided with sliding grooves 15. The slider 22 is slidably installed inside the sliding groove 15. A spring seat is installed at the lower end of the inner wall of the sliding groove 15. A support spring 16 is provided inside the spring seat. The upper end of the support spring 16 contacts the lower outer wall of the slider 22. The slider 22 is elastically connected to the inner wall of the sliding groove 15 through the support spring 16.

[0031] In use, the support spring 16 supports the slider 22 and the support frame 2. After the transparent cover 11 is released from the buckle 12 and flipped, the spring force can push the slider 22 and the support frame 2 to move upward, maintaining the position of the support plate 3, which is convenient for the staff to pick up and put down the sample. After the transparent cover 11 flips and resets, the driving force of the linkage rod 35 on the support plate 3 drives the support plate 3 and the support frame 2 to move downward and reset. At this time, the slider 22 compresses and stores energy in the support spring 16.

[0032] For sealing purposes, exemplarily, such as Figure 4 As shown, a sealing gasket 31 for providing a seal is bonded to the outer wall of the support plate 3, and the sealing gasket 31 is in contact with the inner wall of the housing 1.

[0033] During use, the sealing gasket 31 enhances the sealing between the support plate 3 and the inner wall of the chamber 1, preventing salt spray from leaking from the gap between the support plate 3 and the chamber 1, and ensuring the stability of the test environment.

[0034] For guidance, exemplified, such as Figure 4 As shown, the outer wall of the support plate 3 has through holes 33 arranged in a rectangular array. The upper outer wall of the support frame 2 is screwed with guide rods 21 arranged in a rectangular array. The size of the guide rods 21 is smaller than the inner wall size of the through holes 33, and the guide rods 21 are movably installed inside the through holes 33.

[0035] During use, the guide rod 21 and the through hole 33 play a guiding role when the support plate 3 moves up and down, ensuring that the support plate 3 can move smoothly.

[0036] To adjust the usage location, for example, such as Figure 5 As shown, the support plate 3 has a screw hole inside that is adapted to the screw 23, and the screw 23 is threaded into the screw hole. The upper outer wall of the support plate 3 is screwed to both sides of the storage tray 32.

[0037] During use, staff can place samples into the two storage baskets respectively, enabling the differentiation of different types of samples. The support plate 3 can be precisely adjusted by rotating the screw 23 through the screw hole and screw rod 23, thus allowing for adjustment of the internal range of the detection chamber inside the box 1.

[0038] For example, to enable coordinated movement, such as... Figure 4 As shown, sleeves 34 are installed on both sides of the inner wall of the transparent cover plate 11 and both sides of the outer wall of the upper end of the support plate 3. The sleeves 34 are connected to the linkage rod 35 by the pin inside.

[0039] In use, when the transparent cover 11 is opened or closed, the linkage rod 35 will drive the support plate 3 to move together, realizing the linkage opening and closing of the transparent cover 11 and the support plate 3. When the support plate 3 moves upward, the linkage rod 35 can push the transparent cover 11 to flip open. When the operator flips the transparent cover 11 to reset, the transparent cover 11 drives the support plate 3 to move downward to reset through the retainer 34 and the linkage rod 35, ensuring that the movement of the support plate 3 and the transparent cover 11 is coordinated.

[0040] In use, the buckles 12 on both sides of the outer wall of the box 1 are opened. Since the transparent cover 11 is connected to the box 1 by a hinge, the cover is rotated circumferentially around the hinge by the handle, so that the box 1 is freed from the cover of the transparent cover 11, exposing the internal detection chamber. At this time, the elastic force of the support spring 16 pushes the slider 22 to move vertically upward in the slide groove 15. The slider 22 drives the support frame 2 and the support plate 3 to move upward, so that the support plate 3 carries the storage tray 32 out of the detection chamber. The staff places different types of samples into the storage trays 32 on both sides of the upper outer wall of the support plate 3. The operator manually rotates the screw 23 on the support frame 2. Because the screw hole inside the support plate 3 is threadedly connected to the screw 23, the support plate 3 is driven to move vertically, thereby adjusting the distance between the support plate 3 and the support frame 2. When the support plate 3 moves back to the lower end of the box 1, the distance between the support plate 3 and the upper end of the detection chamber can be adjusted to match the size of the sample to be tested, thereby improving the coverage efficiency of the sodium chloride solution and enhancing the equipment's adaptability to testing samples of different sizes. The operator resets the transparent cover 11 by flipping it over. During this reset process, the linkage rod 35, connected by the internal pins of the sleeves 34 on both sides of the inner wall of the transparent cover 11 and the outer wall of the upper end of the support plate 3, functions. The transparent cover 11 drives the support plate 3 to move downward and reset through the sleeves 34 and the linkage rod 35. At this time, the slider 22 compresses and stores energy in the support spring 16. Simultaneously, the sealing gasket 31 on the outer wall of the support plate 3 is in close contact with the inner wall of the box 1, enhancing the sealing between the support plate 3 and the inner wall of the box 1. The operator can precisely control the temperature, humidity, spraying time and other parameters of the test chamber through the control module 13 on the outer wall of one side of the chamber 1 to ensure that the test environment of the sample inside the chamber 1 is controlled. The atomizing device used with the test chamber inputs the atomized sodium chloride solution into the air inlet 14 that is equidistantly distributed on one side of the inner wall of the chamber 1. The sodium chloride solution is evenly delivered to the detection chamber inside the chamber 1 through the air inlet 14. After the test is completed, the staff opens the buckle 12 and opens the transparent cover 11 through the handle. The elastic force of the support spring 16 pushes the slider 22, the support frame 2 and the support plate 3 to move vertically upward, so that the support plate 3 carries the tray 32 out of the test cavity, making it convenient for the staff to take out the sample in the tray 32.
