Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a portable water surface water quality testing device. Background Technology

[0002] Humans cannot live without water, and the quality of drinking water is closely related to human health. With the development of the social economy, scientific progress, and the improvement of people's living standards, people's requirements for the quality of drinking water are constantly increasing, and drinking water quality standards are also constantly developing and improving. Water quality testing instruments are scientific products used for water quality testing. Water quality testing instruments can detect the components in sampled water resources to determine whether the quality of water resources meets the needs of various domestic or industrial uses. Generally, water quality testing instruments are only required to have characteristics such as intuitive data display and high detection sensitivity. However, in the actual process of water quality testing, there are various usage scenarios. In order to meet the needs of staff, portable water quality testing devices have been developed, as follows.

[0003] A search revealed patent CN218594987U, which discloses a portable water quality testing device, relating to the field of water quality testing equipment technology. The device includes a protective case and the water quality testing equipment, which is mounted inside the protective case. This portable water quality testing device, through the combined use of a buffer plate, an air pump, a fixing plate, and an air bladder, allows the bottom of the water quality testing device to fit into a groove in the buffer plate when placed inside the protective case, simultaneously positioned between the fixing plate and the air bladder. For auxiliary fixation, the air pump is powered on, and air is introduced into the air bladder through a connecting tube. After the air bladder inflates, its outer surface adheres to the outer surface of the water quality testing device, thus achieving overall compression and fixation of the device. This reduces the number of related structures within the protective case, thereby reducing the overall volume of the case and further improving the portability of the portable water quality testing device.

[0004] However, the aforementioned portable water quality testing device still has the following areas for improvement. For example, it uses components such as a buffer plate, air pump, fixing plate, airbag, damping sleeve, and buffer spring to achieve shock absorption and fixation of the water quality testing equipment. However, the large number of components results in a large space occupation inside the protective box, increasing the overall size and weight, which affects portability. In addition, before each use, the air pump must be operated to inflate the airbag to fix the device. After testing or maintenance, the airbag must be deflated before the device can be removed. The operation steps are numerous, affecting the efficiency of on-site testing. At the same time, the air pump requires an external power supply, which is inconvenient to use in outdoor scenarios without power. Therefore, there is an urgent need for a portable surface water quality testing device to solve the above technical problems. Utility Model Content

[0005] This utility model discloses a portable surface water quality testing device. It features a quick-release testing mechanism that allows for rapid fixation of the device using magnets and an iron plate, eliminating the need for components like an air pump. This reduces structural complexity, saves internal space, and lowers overall size and weight, enhancing portability. Simply gripping the handle to overcome magnetic force eliminates the need for inflation / deflation, improving testing efficiency. Furthermore, it requires no external power supply, making it suitable for outdoor use. In addition, a low-carbon steel shielding plate prevents magnetic interference, while rubber blocks provide cushioning, positioning posts assist in positioning, and the positioning posts, combined with a sponge sleeve, ensure device stability and prevent damage from shaking and vibration. This device is highly practical and solves the problems described in the background technology.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a portable water surface quality testing device, including a box body. The top of the box body is rotatably connected to a box cover via a damping shaft. A handle is fixedly connected to the front of the box body. Four support legs are fixedly connected to the bottom of the box body. Insertion slots are opened inside the four support legs. A through groove is opened on the bottom surface of the box body that matches the position and size of the insertion slots and is connected to them.

[0008] A quick-assembly testing mechanism includes a testing instrument and magnets. A shielding plate is fixedly connected to the bottom of the testing instrument. Multiple rubber blocks are fixedly adhered to the bottom of the shielding plate. An iron plate is fixedly adhered to the bottom of the multiple rubber blocks. Multiple magnets are provided and are all adhered and fixed to the inner bottom surface of the housing. The iron plate is magnetically attracted to the multiple magnets. Four positioning posts are fixedly connected to the bottom of the shielding plate and are respectively inserted into four insertion slots.

[0009] A locking mechanism is located at the box body and the box cover.

[0010] Furthermore, the shielding plate is made of low-carbon steel, and the size of the shielding plate is larger than the bottom size of the detector, while the size of the shielding plate is smaller than the internal size of the enclosure.

[0011] Furthermore, the top of the shielding plate is provided with handles near both sides, and the top of the handles is higher than the top opening height of the box.

[0012] Furthermore, an annular sponge sleeve is fixedly attached to the inner wall of the insertion slot, and the inner wall surface of the sponge sleeve is attached to the outer wall of the positioning post.

[0013] Furthermore, the bottom end of the positioning post is designed with an arc shape, and the bottom of the positioning post does not contact the inner bottom surface of the insertion slot.

[0014] Furthermore, the locking mechanism includes connecting blocks and fixing blocks, with two connecting blocks and two fixing blocks. Both connecting blocks are fixedly connected to the front of the lid, and the bottom height of the connecting block is lower than the bottom height of the lid. A through-hole limiting groove is provided inside the connecting block. Both fixing blocks are fixedly connected to the front of the box body. An L-shaped pull rod is movably connected through the fixing block. An abutment plate is fixedly connected to the outside of the pull rod, and the pull rod matches and engages with the limiting groove. The two abutment plates are respectively attached to the opposite side of the two connecting blocks. The L-shaped turning ends of the two pull rods are close to each other, and the distance between the L-shaped turning ends of the two pull rods is 5cm-10cm. A spring is sleeved on the outside of the pull rod, and the two ends of the spring are fixedly connected to the abutment plate and the fixing block respectively.

[0015] Furthermore, the back side of the abutment plate is attached to the front side of the box body, and the back side of the abutment plate is a smooth surface.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. This technical solution features a quick-installation testing mechanism. During operation, the magnetic attraction between the magnet and the iron plate allows for rapid installation and fixation of the testing instrument inside the enclosure, eliminating the need for additional power components such as an air pump. This reduces the number of components, minimizes internal space requirements, and consequently decreases overall size and weight, enhancing portability. Furthermore, the instrument can be easily removed from the enclosure by gripping the handle (by overcoming the magnetic attraction), eliminating the need for inflation and deflation, simplifying the process of handling the equipment before and after testing, and effectively improving on-site testing efficiency. It also eliminates the need for an external power supply, making it suitable for outdoor scenarios without power, thus enhancing its practicality. In addition, the shielding plate, made of low-carbon steel, provides electromagnetic shielding protection for the instrument, reducing the impact of magnets on testing accuracy. Rubber blocks provide cushioning during transport, and the insertion positioning of the positioning post and the sponge sleeve surrounding the positioning post further enhance the stability of the instrument inside the enclosure while also providing cushioning protection during transport to prevent damage from shaking. Overall, it boasts high practicality.

[0018] 2. This technical solution incorporates a locking mechanism, allowing for quick locking of the lid and case body after the lid is closed. Simply releasing the lever activates the spring, pushing the abutment plate to engage the lever in the limiting groove of the connecting block. To open the lid, a single person can easily pull the L-shaped bends of the two levers (the spacing is designed for easy one-handed operation; the thumb and forefinger can be used to pull the levers together) to disengage them from the limiting groove. This convenient and efficient operation further enhances the device's usability, ensuring quick opening and closing of the case during outdoor testing. This protects the internal testing equipment while improving work efficiency, eliminating the need for multiple operators. The close fit between the abutment plate and the front of the case body, along with the tight engagement of the lever and the limiting groove, ensures stability after locking, preventing accidental opening of the lid during transport and further improving its practicality.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0030] Reference Figures 1-6 A portable water surface quality testing device includes a box body 1. The top of the box body 1 is rotatably connected to a box cover 2 via a damping pivot. A handle 3 is fixedly connected to the front of the box body 1. Four support legs 4 are fixedly connected to the bottom of the box body 1. Insertion slots 5 are provided inside the four support legs 4. A through groove 6 is provided on the bottom surface of the box body 1, which matches the position and size of the insertion slots 5 and is connected to them.

[0031] The quick-installation testing mechanism 7 includes a testing instrument 701 and magnets 702. A shielding plate 703 is fixedly connected to the bottom of the testing instrument 701. Multiple rubber blocks 704 are fixedly adhered to the bottom of the shielding plate 703. An iron plate 705 is fixedly adhered to the bottom of the multiple rubber blocks 704. Multiple magnets 702 are provided and are all adhered and fixed to the inner bottom surface of the housing 1. The iron plate 705 is magnetically attracted to the multiple magnets 702. Four positioning posts 706 are fixedly connected to the bottom of the shielding plate 703. The four positioning posts 706 are respectively inserted into four insertion slots 5. A locking mechanism 8 is located at the housing 1 and the cover 2.

[0032] The shielding plate 703 is made of low carbon steel, and its size is larger than the bottom size of the detector 701, while its size is smaller than the internal size of the housing 1. The top of the shielding plate 703 is provided with handles 707 near both sides, and the top height of the handles 707 is higher than the top opening height of the housing 1. An annular sponge sleeve 9 is fixedly attached to the inner wall of the insertion slot 5, and the inner wall surface of the sponge sleeve 9 is attached to the outer wall of the positioning post 706. The bottom end of the positioning post 706 is designed with an arc shape, and the bottom of the positioning post 706 does not contact the inner bottom surface of the insertion slot 5.

[0033] In practical implementation, during operation, the operator holds the handles 707 on both sides of the top of the shielding plate 703 of the detector 701 with both hands, aligning the four positioning posts 706 at the bottom of the detector 701 with the insertion slots 5 inside the support legs 4 at the bottom of the housing 1. Because the bottom of the positioning posts 706 is arc-shaped, it guides them smoothly into the insertion slots 5. The sponge sleeve 9 fits against the outer wall of the positioning posts 706, initially limiting the horizontal swaying of the detector 701. Simultaneously, the detector 701 is slowly lowered, causing the iron plate 705 at the bottom of the shielding plate 703 to gradually approach the magnetic field on the bottom surface inside the housing 1. When the positioning post 706 is inserted to the position where it does not contact the bottom of the insertion slot 5, the iron plate 705 and the magnet 702 are completely attached. With the help of the magnetic attraction between the two, the detector 701 is quickly fixed in the box 1. At this time, the shielding plate 703 can cover the bottom of the detector 701 and maintain a gap with the inner wall of the box 1. Its low carbon steel material can isolate the interference of the magnet 702. The rubber block 704 at the bottom is sandwiched between the shielding plate 703 and the iron plate 705 to form a buffer layer. At this point, the detector 701 is installed and is in a stable state ready for testing or ready for storage.

[0034] The shielding plate 703 is made of low carbon steel so that it has a certain magnetic field shielding effect, thereby preventing the magnet 702 from interfering with the detector 701. The size of the shielding plate 703 is larger than the bottom size of the detector 701 to prevent the shielding plate 703 from contacting the inside of the housing 1.

[0035] Among them, the handle 707 is designed to facilitate the installation and removal of the testing instrument 701 by the operator;

[0036] Among them, the sponge sleeve 9 can prevent the positioning post 706 from rigidly contacting the insertion slot 5. When carrying and transferring, the sponge sleeve 9 can buffer the shaking and vibration to a certain extent, thereby protecting the detector 701.

[0037] The bottom of the positioning post 706 is designed with an arc shape to better guide the positioning post 706 into the insertion slot 5. The fact that the bottom of the positioning post 706 does not contact the inner bottom surface of the insertion slot 5 makes it easier for the positioning post 706 to move up and down in the insertion slot 5. The elastic deformation of the rubber block 704 plays a buffering and protective role.

[0038] Among them, magnets 702 are arranged in a rectangular array on the bottom surface of the inner side of the box 1, and the magnetic strength of magnets 702 is N35 neodymium iron boron grade. Specific Implementation Example 2:

[0040] Reference Figure 1 and Figure 2In a preferred embodiment, the locking mechanism 8 includes two connecting blocks 801 and two fixing blocks 802. Both connecting blocks 801 are fixedly connected to the front of the lid 2, and the bottom height of the connecting blocks 801 is lower than the bottom height of the lid 2. A through-hole limiting groove 803 is provided inside the connecting blocks 801. Both fixing blocks 802 are fixedly connected to the front of the box body 1, and an L-shaped pull rod 8 is movably inserted through the fixing blocks 802. 04. The pull rod 804 is externally fixedly connected to an abutment plate 805, and the pull rod 804 is matched and engaged with the limiting groove 803. The two abutment plates 805 are respectively attached to the opposite side of the two connecting blocks 801. The L-shaped turning ends of the two pull rods 804 are close to each other, and the distance between the L-shaped turning ends of the two pull rods 804 is 5cm-10cm. A spring 806 is sleeved on the outside of the pull rod 804. The two ends of the spring 806 are fixedly connected to the abutment plate 805 and the fixing block 802 respectively.

[0041] The back side of the abutment plate 805 is attached to the front side of the box 1, and the back side of the abutment plate 805 is a smooth surface.

[0042] In the specific implementation process, in the initial state of the device, the cover 2 is kept closed to the box body 1 by the locking mechanism 8. When opening the cover 2, the operator needs to hold the L of the two pull rods 804 in the locking mechanism 8. The two ends of the bend (5cm-10cm apart for easy one-person, one-handed operation) are pulled towards each other. At this time, the pull rod 804 drives the externally fixed abutment plate 805 to move synchronously, which compresses the spring 806 sleeved on the outside of the pull rod 804. As the pull rod 804 moves, the end away from the bend gradually disengages from the limiting groove 803 on the connecting block 801, releasing the locking constraint on the connecting block 801. When the pull rod 804 is completely disengaged from the limiting groove 803, the abutment plate 805 separates from the connecting block 801, the locking state of the locking mechanism 8 is released, and the operator can flip the box cover 2 upward through the damping shaft until the box cover 2 is opened to an angle that is easy to operate (the damping shaft can keep the box cover 2 at any opening angle without additional support), exposing the inner cavity of the box 1 and the detector 701.

[0043] After completing the inspection, the operator flips the lid 2 downwards until it is completely flush with the top opening of the box 1 (the damping shaft helps control the flipping speed to prevent the lid 2 from rapidly impacting the box 1). At this point, the two connecting blocks 801 on the front of the lid 2 are directly above the two fixing blocks 802 on the front of the box 1. The limiting groove 803 on the connecting block 801 is aligned with the axis of the pull rod 804 at the fixing block 802. Then, the operator releases the tension on the locking mechanism 8 pull rod 804, and the compressed spring 806 releases its elastic potential energy, pushing the abutment plate 805 closer to the locking mechanism 8. As the connecting block 801 moves in a certain direction, the abutment plate 805 drives the pull rod 804 to move synchronously. Since the back of the abutment plate 805 is in contact with the front of the box 1, it remains stable during the movement. Finally, the end of the pull rod 804 away from the turning end is precisely inserted into the limiting groove 803 of the connecting block 801, completing the locking constraint of the connecting block 801. At the same time, the abutment plate 805 is tightly attached to the opposite side of the connecting block 801, further restricting the displacement of the connecting block 801. The locking mechanism 8 returns to the locked state, and the box cover 2 and the box 1 are firmly closed to prevent the detector 701 from shaking inside the box.

[0044] The back side of the abutment plate 805 is attached to the front side of the box 1 to improve the stability of the pull rod 804 and the abutment plate 805, while the back side of the abutment plate 805 is a smooth surface to reduce the friction and wear between the abutment plate 805 and the box 1.

[0045] The fitting clearance between the pull rod 804 and the limiting groove 803 is 0.2mm, and the depth to which the pull rod 804 is inserted into the limiting groove 803 is not less than 10mm.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
