Description

Technical Field

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

[0002] As a daily personal care product, the quality and performance of razor blades directly impact the user experience and safety. In actual use, razor blades frequently come into contact with water, sweat, and various corrosive substances in the air, especially in high-humidity or coastal environments where they face even more severe corrosion challenges. Salt spray testing, as an accelerated corrosion testing method, simulates saline environments such as marine or industrial atmospheres, allowing for the rapid assessment of the corrosion resistance of materials or products. In salt spray testing, razor blades are exposed to a salt spray environment containing a certain concentration of sodium chloride solution, and the time and extent of corrosion on the blade surface are observed to determine whether its corrosion resistance meets design requirements.

[0003] Currently, different test samples typically require placement at different angles. For example, according to testing standards, blades must be placed between 15 and 20 degrees. However, the placement fixtures in existing salt spray test chambers are mostly fixed structures. Adjusting the sample placement angle requires changing different fixtures, which is inconvenient and reduces the practicality of the device. Therefore, to address the above technical problems, a salt spray test chamber is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a salt spray test chamber that facilitates the adjustment of the sample placement angle, thereby improving the practicality of the device.

[0005] A salt spray test chamber includes a salt spray chamber body and at least one set of placement fixtures, wherein the placement fixtures are made of plastic and include:

[0006] The mounting base is horizontally slidable on two sets of guide rods inside the salt spray chamber body;

[0007] A placement plate for placing test samples, one end of which is hinged to the mounting base; and

[0008] The rotating assembly includes a worm gear and a worm. The worm gear is coaxially mounted on the hinge shaft of the placement plate, and the worm is rotatably mounted on the mounting base and meshes with the worm gear.

[0009] The beneficial effects of the above-mentioned salt spray test chamber are as follows:

[0010] By rotating the worm gear, the worm gear meshes with the worm wheel, driving the worm wheel to rotate. The rotation of the worm wheel drives the placement plate to rotate via the hinge shaft. The rotation of the placement plate can adjust the tilt angle of the placement plate, thereby adjusting the placement angle of the sample. When the placement plate is adjusted to the specified tilt angle, the rotation of the worm gear stops, and the worm gear meshes with the worm wheel to form a self-locking mechanism. At this point, the tilt angle of the placement plate can be fixed, eliminating the need for additional fixing components to secure the placement plate. Adjusting the placement angle of the sample is convenient, and the mounting base can slide horizontally within the salt spray chamber. The sliding of the mounting base drives the sliding of the placement plate, thus facilitating the adjustment of the horizontal position of the sample and improving the practicality of the device.

[0011] In one embodiment, the mounting base further includes a base plate, and two sets of guide grooves are provided opposite to each other at the bottom end of the mounting base. The two sets of guide grooves are sleeved on the two sets of guide rods. The base plate is detachably mounted on the mounting base and covers the bottom openings of the two sets of guide grooves.

[0012] In one embodiment, the base plate is provided with spring clips at both ends, and the mounting base is provided with clip slots at both ends, with the two sets of spring clips respectively engaged in the two sets of clip slots.

[0013] In one embodiment, the inner walls of the two sets of guide grooves are respectively frictionally attached to the periphery of the two sets of guide rods.

[0014] In one embodiment, the placement fixture further includes an arc-shaped angle ruler and an indicator; the arc-shaped angle ruler is disposed on one side of the mounting base, and the indicator is disposed on one side of the placement plate; the placement plate can be rotated to make the indicator correspond to any angle line on the arc-shaped angle ruler.

[0015] In one embodiment, a stop is provided on the top surface of the end of the placement plate near the hinge axis, and multiple sets of the stop are spaced apart along the axial direction of the hinge axis.

[0016] In one embodiment, the two ends of the stop are provided with guide slopes opposite each other, and the ends of the two sets of guide slopes away from the hinge axis are connected to form a tip. Attached Figure Description

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] Please see Figures 1 to 4 One embodiment of a salt spray test chamber includes a salt spray chamber body 1 and at least one set of placement fixtures 2. The placement fixtures 2 are made of plastic and include a mounting base 20, a placement plate 21, and a rotating assembly. The mounting base 20 is horizontally slidably mounted on two sets of guide rods 10 inside the salt spray chamber body 1. The placement plate 21 is used to place test samples, and one end of the placement plate 21 is hinged to the mounting base 20. The rotating assembly includes a worm gear 22 and a worm 23. The worm gear 22 is coaxially mounted on the hinge shaft of the placement plate 21, and the worm 23 is rotatably mounted on the mounting base 20 and meshes with the worm gear 22.

[0026] In the above embodiment, by rotating the worm 23, the worm 23 rotates and meshes with the worm wheel 22, driving the worm wheel 22 to rotate. The rotation of the worm wheel 22 drives the placement plate 21 to rotate through the hinge shaft. The rotation of the placement plate 21 can adjust the tilt angle of the placement plate 21, thereby adjusting the placement angle of the sample. When the placement plate 21 is adjusted to the specified tilt angle, the rotation of the worm 23 is stopped, and the worm 23 stops rotating and meshes with the worm wheel 22 to form a self-locking mechanism. At this time, the tilt angle of the placement plate 21 can be fixed, without the need for additional fixing parts to fix the placement plate 21. Adjusting the placement angle of the sample is convenient, and the mounting base 20 can slide horizontally within the salt spray chamber body 1. The sliding of the mounting base 20 can drive the placement plate 21 to slide, thereby facilitating the adjustment of the horizontal position of the sample and improving the practicality of the device.

[0027] It is understandable that the salt spray chamber body 1 is existing technology, and its working principle will not be elaborated here.

[0028] Please see Figure 2 and Figure 3 In one embodiment, the mounting base 20 further includes a base plate 201. Two sets of guide grooves 202 are provided opposite to each other at the bottom end of the mounting base 20. The two sets of guide grooves 202 are sleeved on the two sets of guide rods 10. The base plate 201 is detachably mounted on the mounting base 20 and covers the bottom openings of the two sets of guide grooves 202.

[0029] The two sets of guide grooves 202 cooperate with the two sets of guide rods 10, which facilitates the horizontal sliding of the mounting base 20 along the guide rods 10. By removing the base plate 201, the bottom openings of the two sets of guide grooves 202 are opened. At this time, the mounting base 20 can be moved upward to remove the placement fixture 2, which is convenient for the inspection, maintenance or replacement of the placement fixture 2.

[0030] Based on the above embodiments, the base plate 201 is further provided with spring clips 203 at both ends, and the mounting base 20 is provided with clip slots 204 at both ends, with the two sets of spring clips 203 respectively engaging in the two sets of clip slots 204. The base plate 201 is connected to the mounting base 20 via the two sets of spring clips 203, making it convenient to install and remove the base plate 201.

[0031] Based on the above embodiments, further, the inner sidewalls of the two sets of guide grooves 202 are respectively frictionally fitted with the periphery of the two sets of guide rods 10. This facilitates the lowering and fixing of the mounting base 20 onto the two sets of guide rods 10 without external force. When it is necessary to move the mounting base 20, only an external force greater than the friction between the guide grooves 202 and the guide rods 10 needs to be applied to the moving direction of the mounting base 20, making it convenient to move and fix the mounting base 20.

[0032] Please see Figure 2 and Figure 3 In one embodiment, the placement fixture 2 further includes an arc-shaped angle ruler 24 and an indicator 241. The arc-shaped angle ruler 24 is disposed on one side of the mounting base 20, and the indicator 241 is disposed on one side of the placement plate 21. The placement plate 21 can be rotated so that the indicator 241 corresponds to any angle mark on the arc-shaped angle ruler 24. In the above embodiment, the tilt angle of the placement plate 21 can be directly obtained by observing the angle mark corresponding to the indicator 241, making it convenient and accurate to adjust the placement plate 21 to the specified tilt angle.

[0033] Please see Figure 3 and Figure 4In one embodiment, a stop 25 is provided on the top surface of the end of the placement plate 21 near the hinge shaft, and multiple sets of stop 25 are spaced apart along the axial direction of the hinge shaft. In the above embodiment, by providing multiple sets of stop 25, the sample can be prevented from slipping off the placement plate 21 when it slides downward along the placement plate 21 due to gravity, and the spaced arrangement of multiple sets of stop 25 facilitates the drainage of water condensed on the placement plate 21 through the gaps between the multiple sets of stop 25, avoiding water accumulation that could affect the test.

[0034] Based on the above embodiment, furthermore, the two ends of the baffle 25 are provided with guide slopes 251 facing each other, and the ends of the two sets of guide slopes 251 away from the hinge axis are connected to form a tip. This can reduce the contact area between the baffle 25 and the sample, thereby avoiding the phenomenon of water accumulation at the contact point between the baffle 25 and the sample, and further preventing water accumulation from affecting the test.

[0035] The specific implementation method of the above-mentioned salt spray test chamber is as follows:

[0036] By rotating the worm 23, the worm 23 meshes with the worm wheel 22, driving the worm wheel 22 to rotate. The rotation of the worm wheel 22 drives the placement plate 21 to rotate via the hinge shaft. The rotation of the placement plate 21 can adjust the tilt angle of the placement plate 21, thereby adjusting the placement angle of the sample. When the rotation of the placement plate 21 makes the indicator 241 correspond to the specified angle mark, the rotation of the worm 23 is stopped. The worm 23 stops rotating and meshes with the worm wheel 22 to form a self-locking mechanism. At this time, the tilt angle of the placement plate 21 can be fixed without the need for additional fixing parts to fix the placement plate 21. Adjusting the placement angle of the sample is convenient and accurate. Furthermore, by applying an external force greater than the friction between the guide groove 202 and the guide rod 10 in the moving direction of the mounting base 20, the mounting base 20 can be made to slide. The sliding of the mounting base 20 can drive the placement plate 21 to slide, thereby facilitating the adjustment of the horizontal position of the sample. When the sample is in a suitable horizontal position, the external force applied to the mounting base 20 can be removed, improving the practicality of the device.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
