Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a wastewater chemical analysis tool for environmental monitoring. Background Technology

[0002] Environmental monitoring is an important means of protecting water resources and assessing the degree of water pollution. Among them, rapid and accurate chemical analysis of wastewater samples is a key link. Therefore, various portable or on-site wastewater chemical analysis tools are widely used.

[0003] Such analytical tools typically require an analytical chamber or sample compartment to hold wastewater samples, and are equipped with a flap or door to protect the delicate sensors, optical components and chemical reagents inside from interference and contamination from the external environment.

[0004] In practical applications of environmental monitoring, especially in fields, mines, or sewage outlets, the operating environment is often very harsh. The equipment will inevitably come into contact with a large amount of mud, dust, sewage, and be exposed to wind and rain.

[0005] Most existing wastewater chemical analysis tools use traditional locking structures for their flip covers, such as mechanical latches, push-button latches, or knob locks. These locking structures usually protrude from the surface of the equipment housing or are directly exposed for ease of operation.

[0006] This exposed design allows mud, sand, and dirt to seep into and clog the moving parts and precision gaps of the locking mechanism, or cause them to rust and jam in humid and corrosive environments. This not only makes it difficult to open the flip cover or causes it to lock properly, seriously affecting the ease of use for on-site operators, but more importantly, once the locking structure fails and the sealing performance deteriorates, external pollutants and moisture will enter the analysis chamber, directly contaminating the precision sensors, causing inaccurate chemical analysis data, and greatly shortening the reliable service life of the equipment.

[0007] Therefore, this utility model proposes a wastewater chemical analysis tool for environmental monitoring to address the shortcomings of existing technologies. Utility Model Content

[0008] In view of the problems existing in the field of wastewater chemical analysis tools for environmental monitoring, such as the locking mechanism being exposed, being susceptible to jamming and failure due to silt and wastewater contamination, resulting in decreased sealing performance and inconvenience in operation, this utility model aims to provide an environmental monitoring wastewater chemical analysis tool with an improved structure that can effectively solve the above problems.

[0009] This utility model provides a wastewater chemical analysis tool for environmental monitoring, comprising: a main body two; and a flip cover that is rotatably connected to the top rear side of the main body two via a hinge.

[0010] It also includes a lock head fixed to the front side of the bottom of the flip cover, a housing hidden and fixed to the front end of the main body, a lock block connected to the housing by a rotating shaft, a spring one sleeved on the rotating shaft, a limiting post fixed to the bottom of the inner side of the housing, a spring two sleeved inside the limiting post, and a ball movably set inside the housing.

[0011] The lock head has a slot, and the housing is hidden and fixed to the front end of the main body, so that the lock head can fit into the housing when the flip cover is closed. The hidden design uses the outer shell of the main body to protect the internal precision locking components.

[0012] Furthermore, the locking block is rotatably connected to the upper middle part of the inner side of the housing via a rotating shaft, and its structure is adapted to be inserted into the slot of the lock head to achieve locking; the spring is sleeved on the rotating shaft and is used to apply preload to push the locking block into the slot; the limiting post is fixed to the bottom of the inner side of the housing; the second spring is sleeved inside the limiting post; the ball is movably disposed in the housing and limited by the limiting post, the ball is elastically supported by the second spring and is used to abut against the lock head, and the reciprocating motion of the lock head is configured to compress the second spring and simultaneously drive the locking block to rotate to disengage from the slot, thereby realizing the complete function of pressing to lock and pressing again to unlock.

[0013] Preferably, the wastewater chemical analysis tool for environmental monitoring further includes a main body one, a second main body fixedly mounted on the main body one, and a mounting foot fixed to the bottom of the main body one. The mounting foot is used to increase the contact stability between the equipment and the placement surface, so that it can be stably placed on uneven ground in the field.

[0014] Preferably, as a specific implementation, the main body also integrates a display screen for displaying analysis results and buttons for operation, which facilitates human-computer interaction, real-time data viewing and input of control commands by operators.

[0015] Preferably, the bottom of the lock head has a rounded corner structure. The rounded corner structure, as a smooth transition surface, is configured to smoothly contact the ball and push the lock block to rotate during the closing process of the flip cover, thereby reducing the impact and friction during the locking process and improving the smoothness of operation.

[0016] Preferably, the spring is configured to generate and store a preload when the lock block is rotated by the lock head, and after the lock block disengages from the slot of the lock head, the spring releases the stored preload, pushing the lock block to rotate around the pivot and reset to the initial standby state, preparing for the next locking.

[0017] Preferably, the second spring is configured such that when the flip cover is locked by the locking block into the slot, the second spring is kept in a compressed, energy-storing state through the ball and the lock head, providing a power source for subsequent unlocking and popping.

[0018] Preferably, the limiting post is used to restrict the compression direction of the second spring, ensuring that the second spring can only be compressed and released along its axial direction, i.e., the vertical direction, so as to prevent the second spring from deflecting, bending or buckling when subjected to force, thus ensuring the reliability of the mechanism.

[0019] Preferably, the ball is disposed between the lock head and the second spring. The ball is used to increase the contact area for force transmission between the two, avoiding direct contact wear between the bottom of the lock head and the second spring. In addition, its rolling characteristics can reduce the friction when the lock head moves, making the pressing feel smoother.

[0020] This utility model has the following beneficial effects: 1. This utility model, by concealing the entire locking assembly, including the lock head, shell, lock block, spring one, spring two, and ball, inside the main body two, and using the outer wall of the main body two to protect the locking assembly, solves the problem in the prior art where the locking mechanism of environmental monitoring tools is exposed to the outside and is corroded or jammed by pollutants such as sewage, mud, and dust, leading to the failure of the flip cover seal or the inability to open and close normally. It achieves the effect of effectively protecting the precision locking structure and improving the reliability and durability of the equipment for long-term use in harsh environments.

[0021] 2. This utility model achieves the function of "pressing to lock and pressing again to open" by using the slot on the lock head to engage with the lock block and utilizing the synergistic action of spring one and spring two. It solves the problem that the existing flip cover uses traditional buckles or key locks, which leads to cumbersome operation and inconvenience for on-site personnel wearing gloves to operate with one hand. It achieves the effect of simplifying the opening and closing steps and improving on-site work efficiency and convenience.

[0022] 3. This utility model solves the problem that existing equipment will shake or tip over when placed on uneven ground in the field, affecting the accuracy of internal chemical analysis, by setting a mounting foot at the bottom of the main body. This achieves the effect of making the equipment more stable and ensuring the reliable conduct of analysis work. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example: Please refer to Figures 1 to 4 This utility model provides a wastewater chemical analysis tool for environmental monitoring, which aims to solve the problems in the prior art where the locking mechanism of environmental monitoring equipment is subject to silt pollution and corrosion due to exposure to harsh outdoor environments, resulting in jamming or sealing failure, and the inconvenience of traditional locking operation.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, a wastewater chemical analysis tool for environmental monitoring includes a second main body 2 and a first main body 1 fixedly installed below the second main body 2. The first main body 1 serves as the support base for the entire analysis tool, with four fixed mounting feet 6 at its bottom corners. The mounting feet 6 ensure that the first main body 1 remains stable on uneven outdoor ground. A display screen 4 and buttons 5 are embedded in the front or top surface of the first main body 1. The buttons 5 are electrically connected to the control circuit inside the second main body 2, allowing operators to input analysis commands and select function modes. The display screen 4 processes the electrical signals detected and converted by the internal sensors into visualized wastewater chemical analysis results. The second main body 2 serves as the core analysis chamber, with internal space used to accommodate bottled wastewater samples to be tested, as well as corresponding detection reagents and sensor components. To provide sealed protection for the interior of the second main body 2, the main body 1... The top rear side of body 2 is rotatably connected to a flip cover 3 via a hinge 7. The flip cover 3 can rotate up and down relative to body 2 around the axis of the hinge 7, thereby opening and closing the sampling port at the top of body 2. After the operator opens the flip cover 3, the sewage sample can be placed inside body 2. To achieve convenient and reliable locking and opening of the flip cover 3, a lock head 8 is fixedly connected to the bottom front edge of the flip cover 3. At the same time, a housing 9 is hidden and fixedly installed inside the front end of body 2. The housing 9 is located inside the outer shell of body 2 and does not protrude outward, thereby using the outer wall of body 2 to protect the precision mechanical structure inside the housing 9. The position of the lock head 8 corresponds to the opening position at the top of the housing 9. When the flip cover 3 is pressed down and closed by external force, the lock head 8 can smoothly pass through the opening on the surface of body 2 and enter the internal cavity of the housing 9.

[0028] Please refer to Figure 2 , Figure 3 and Figure 4 A locking block 10 is rotatably connected to the upper inner part of the housing 9 via a pivot 11. The locking block 10 has a hook-shaped structure for engaging the lock head 8. A spring 12 is sleeved on the rotating shaft 11. The two ends of the spring 12 abut against the inner wall of the housing 9 and the non-working surface of the locking block 10, respectively. The spring 12 is used to generate a preload when the locking block 10 is rotated by an external force. At the bottom inner side of the housing 9, below the entry path of the lock head 8, a vertically upward limiting post 13 is fixedly connected. A spring 14 is sleeved on the outer periphery of the limiting post 13. The function of the limiting post 13 is to restrict the spring 14 to be compressed and released only in the axial direction, i.e., the vertical direction, to prevent the spring 14 from shifting or bending when compressed. The top of the second spring 14 is elastically supported by a ball 15. The ball 15 is movably disposed within the housing 9 and guided by the limiting post 13. The top part of the ball 15 is exposed above the limiting post 13 and the second spring 14, and is used to directly abut against the bottom of the lock head 8. The arrangement of the ball 15 increases the contact area between the lock head 8 and the second spring 14, and reduces the friction when the lock head 8 moves. At the same time, such as Figure 3 As shown, the lock head 8 fixed to the flip cover 3 has a specific structure adapted to the locking assembly. The side wall of the lock head 8 is provided with a slot for engaging with the lock block 10, and the bottom of the lock head 8 has a rounded corner structure. In the assembled state, when the flip cover 3 is closed, the rounded corner structure of the lock head 8 first contacts the ball 15 and presses the second spring 14 down together. At the same time, the rounded corner structure will also squeeze the lock block 10 to rotate around the pivot 11 and compress the first spring 12. When the lock head 8 is pressed down, the slot moves to the position corresponding to the lock block 10, the preload of the spring 12 is released, and the lock block 10 is pushed to quickly lock into the slot. At this time, the spring 2 14 remains in the compressed state, thus firmly locking the flip cover 3. This press-lock structure ensures the high sealing performance and locking reliability of the flip cover 3 in harsh environments.

[0029] As a preferred embodiment, a wastewater chemical analysis tool for environmental monitoring also includes a main body 1, a second main body 2 fixedly mounted on the main body 1, and mounting feet 6 fixed to the bottom of the main body 1 to improve the stability of the equipment in field use. As a further refinement of the functions of the main body 1, in order to realize human-computer interaction, the main body 1 is equipped with a display screen 4 for displaying analysis results and buttons 5 for operation; As a preferred design for the lock cylinder 8, in order to ensure that the lock cylinder 8 can smoothly trigger the internal components when it enters the housing 9, the bottom of the lock cylinder 8 has a rounded corner structure. The rounded corner structure is configured to smoothly contact the ball 15 and simultaneously push the lock block 10 to rotate during the closing of the flip cover 3. As a specific implementation of the reset function of the lock block 10, the spring 12 is configured to generate a preload when the lock block 10 is rotated by the lock head 8, and after the lock block 10 is disengaged from the slot of the lock head 8, it can immediately push the lock block 10 to rotate around the rotating shaft 11 to reset to the original standby position. As a specific configuration for achieving the locked state, the structure of the second spring 14 is configured such that when the flip cover 3 is locked by the locking block 10 into the slot, the second spring 14 is compressed downward through the ball 15 and the lock head 8 and remains in the compressed state, thereby storing elastic potential energy for subsequent unlocking and popping. To ensure the reliability of the second spring 14, the limiting post 13 is configured to limit the compression direction of the second spring 14, ensuring that the second spring 14 is compressed and released only in the axial vertical direction, so as to prevent the second spring 14 from deflecting or buckling. In order to optimize the force transmission between the lock head 8 and the second spring 14, a ball 15 is disposed between the lock head 8 and the second spring 14. The arc-shaped surface of the ball 15 is used to increase the contact area between the two, and the rolling characteristics of the ball 15 can also reduce the friction when the lock head 8 moves, making the pressing feel smoother.

[0030] Working principle: The operator inputs instructions through button 5, and the display screen 4 displays chemical analysis data. When it is necessary to place a sewage sample, the operator lifts the flip cover 3 and places the bottled sample inside the main body 2. Then, the flip cover 3 needs to be closed. When the flip cover 3 is pressed down to close, the lock head 8 fixed to the flip cover 3 moves and enters the shell 9 hidden inside the main body 2. The rounded corner structure at the bottom of the lock head 8 first contacts and presses the ball 15. The ball 15 then compresses the spring 14 below. In sync with this stroke, the rounded corner structure of the lock head 8 also acts on the locking block 10, forcing the locking block 10 to rotate around the pivot 11 and compress the spring 12. When the flip cover 3 is fully pressed into place, the slot on the side wall of the lock head 8 moves to the corresponding position of the locking block 10. At this time, the spring 12 releases the preload and pushes the locking block 10 to quickly lock into the slot. At this time, the spring 14 remains in the compressed energy storage state, and the flip cover 3 is reliably locked. When the flip cover 3 needs to be opened, the operator presses it down again. The reciprocating motion of the locking head 8 is configured to drive the locking block 10 to rotate again, so that the locking block 10 overcomes the thrust of the spring 12 and disengages from the slot. At the moment the locking block 10 disengages from the slot, the spring 14, which was previously in a compressed state, quickly releases its elastic potential energy and pushes the locking head 8 upward through the ball 15. The locking head 8 drives the flip cover 3 to spring up and open automatically. After the locking head 8 disengages, the spring 12 pushes the locking block 10 to rotate around the pivot 11 to reset, preparing for the next locking. Through the precise synergistic action of the locking head 8, locking block 10, ball 15, spring 12, and spring 14, and the design that hides the entire housing 9 inside the main body 2, this utility model solves the problem that the locks of existing analytical tools exposed to the outside will be contaminated and fail due to impact, while realizing convenient push-to-open and close operation.
