Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and specifically discloses a portable zinc detector in water. Background Technology

[0002] Zinc is an important trace element, but excessive zinc content can cause serious harm to aquatic ecosystems and human health. Therefore, accurate measurement of zinc content in water is crucial for environmental protection and human health.

[0003] The existing portable zinc detectors in water contain all their detection components inside the casing. Because the height of the operating position is limited when the casing is opened, it is very inconvenient for personnel to operate outdoors. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a portable zinc detector in water, including a detector housing and a cover hinged to the top of the detector housing. The bottom of the detector housing is provided with two sets of first fixing plates and second fixing plates, as well as first support plates and second support plates for both. The first fixing plates, second fixing plates, first support plates and second support plates have the same height. The interior of the first fixing plates and second fixing plates are respectively rotatably connected to a first support leg located inside the first support plate and a second support leg located inside the second support plate via first fixing pins. A U-shaped plate is fixedly installed inside the first fixing plate via a second fixing pin. A limit mechanism is installed inside the U-shaped plate. The outer sides of the first support leg and the second support leg are provided with slots.

[0005] Preferably, there are two slots on each of the first and second support legs, and the two slots are distributed at a 90-degree angle.

[0006] Preferably, the limiting mechanism includes a fixed rod that is movably sleeved inside the U-shaped plate. The end face of the fixed rod extending to the inner side of the U-shaped plate is provided with a limiting plate that engages with the inner side of the slot. A pull ring is fixedly fitted on the outer side of the fixed rod extending outside the U-shaped plate. A spring is fitted on the outer side of the fixed rod between the U-shaped plate and the limiting plate.

[0007] Preferably, both the first fixing plate and the second fixing plate are provided with guide grooves that are adapted to the limiting plate.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. This portable zinc detector in water can be moved by pulling the limiting plate through the pull ring, which can move the plate out from the inside of the guide groove. This releases the limiting plate from restricting the first and second support legs, allowing the first and second support legs to unfold 90 degrees one by one. At this time, the first and second support legs can support the detector housing, so that operators can operate the zinc detector in water outdoors to conduct water quality testing.

[0010] 2. This portable zinc detector in water can limit and support the limiting plate through the guide groove, so that the limiting plate will not deflect during the movement, thereby ensuring that the limiting plate can be accurately inserted into the groove under the elastic force of the spring.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0020] The accompanying drawings in this utility model embodiment: different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0021] Please see Figure 1-6 A portable zinc detector for water includes a detector housing 1 and a cover 2 hinged to the top of the housing 1. The bottom of the housing 1 has two sets of first fixing plates 3 and second fixing plates 4, as well as first support plates 5 and second support plates 6. The first fixing plates 3, second fixing plates 4, first support plates 5, and second support plates 6 are all of the same height. This structure prevents the detector housing 1 from shaking when placed on a table, facilitating indoor water quality testing. Simultaneously, the first support plates 5 and second support plates 6 can respectively limit the movement of the first support leg 8 and the second support leg 9, ensuring the detector housing 1 remains stable during transportation. The support leg 8 and the second support leg 9 are not easily bent. The first support leg 8 located inside the first support plate 5 and the second support leg 9 located inside the second support plate 6 are respectively rotatably connected to the first fixed plate 3 and the second fixed plate 4 through the first fixed pin 7. The first support leg 8 and the second support leg 9 adopt a hollow structure design, which can reduce the overall weight of the zinc detector in water, so as to facilitate carrying the zinc detector in water for outdoor water quality testing. The U-shaped plate 11 is fixedly installed inside the first fixed plate 3 through the second fixed pin 10. The U-shaped plate 11 is fitted with a limit mechanism 12. The outer sides of the first support leg 8 and the second support leg 9 are provided with slots 13.

[0022] There are two slots 13 located on the first support leg 8 and the second support leg 9, and the two slots 13 are distributed at 90 degrees. The two slots 13 enable the first support leg 8 and the second support leg 9 to be limited and fixed by the cooperation of the limiting plate 122 and the slots 13 after rotating 90 degrees, so as to facilitate the storage and unfolding of the first support leg 8 and the second support leg 9.

[0023] The limiting mechanism 12 includes a fixed rod 121 movably sleeved inside the U-shaped plate 11. The end face of the fixed rod 121 extending to the inner side of the U-shaped plate 11 is provided with a limiting plate 122 that engages with the inner side of the slot 13. A pull ring 123 is fixedly fitted on the outer side of the end of the fixed rod 121 that extends outside the U-shaped plate 11. The pull ring 123 facilitates the pulling of the fixed rod 121 while moving the limiting plate 122. A spring 124 is fitted on the outer side of the fixed rod 121 between the U-shaped plate 11 and the limiting plate 122. The elastic force of the spring 124 makes it difficult for the limiting plate 122 to disengage from the inside of the slot 13 after it is engaged with the inner side of the slot 13. This prevents the first support leg 8 and the second support leg 9 from automatically unfolding, ensuring that the first support leg 8 and the second support leg 9 can stably limit and support the detector housing 1.

[0024] The first fixing plate 3 and the second fixing plate 4 are both provided with guide grooves 14 that are adapted to the limiting plate 122. The guide grooves 14 can limit and support the limiting plate 122, so that the limiting plate 122 is not easy to bend and deform when subjected to external force.

[0025] When the zinc detector in water is used outdoors, pulling the pull ring 123 by hand moves the limiting plate 122 through the fixing rod 121. When the limiting plate 122 moves out of the inside of the slot 13, it can release the limitation on the first support leg 8 and the second support leg 9. At this time, the first support leg 8 and the second support leg 9 can rotate around the axis of the first fixing pin 7 under their own weight. When the first support leg 8 and the second support leg 9 rotate to 90 degrees, the limiting plate 122 can be automatically locked into the inside of the slot 13 by the elastic force of the spring 124, and then the support push is unfolded one by one. At this time, the detector housing 1 is supported by the first support leg 8 and the second support leg 9. After the housing cover 2 is opened, the relevant detection components placed inside the detector housing 1 can sample and test the water quality.

[0026] After the zinc detector in the water is used, pull the pull ring 123 by hand and move the limiting plate 122 through the fixing rod 121. When the limiting plate 122 moves out of the inside of the slot 13, it can release the limitation on the first support leg 8 and the second support leg 9. At this time, manually rotate the first support leg 8 and the second support leg 9 one by one around the axis of the first fixing pin 7 by 90 degrees. Under the elastic force of the spring 124, the limiting plate 122 can be automatically locked into the inside of the slot 13, and then the support legs can be stored one by one. The contents not described in detail in this description are the prior art known to those skilled in the art.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
