Description

Technical Field

[0001] This utility model relates to the field of water quality fixative technology, and in particular to a device for preserving water quality fixatives from on-site sampling. Background Technology

[0002] Water quality sampling fixative boxes are important tools designed specifically for on-site water quality monitoring. They are designed to ensure that water samples remain stable after collection, prevent changes in composition, and thus ensure the accuracy of experimental data.

[0003] Existing storage boxes typically use a layered design for the sampling tools and fixatives inside, with the fixative at the bottom and the sampling tool at the top. To remove the fixative, the sampling tool at the top needs to be removed, which increases the number of steps, makes the fixative more susceptible to damage, and can easily lead to the sampling tool being left behind after use.

[0004] To address this issue, a device for preserving fixatives in on-site water sampling is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a field sampling water quality fixative preservation device, which aims to improve the existing technology where the sampling tools and fixative inside the preservation box are usually designed in two layers, with the fixative at the bottom and the sampling tool at the top. When you want to remove the fixative, you need to take out the sampling tool at the top, which increases the operation steps, is easy to damage the fixative, and is easy to cause the sampling tool to be missed after use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for preserving fixatives in on-site water sampling includes: a box body, a partition fixedly installed on the inner wall surface of the box body, a cover plate movably connected to the top of the box body via a pivot pin, a metal frame movably connected to the inner wall surface of the cover plate via a pivot pin, a tool box fixedly installed on the front of the metal frame, a clamping mechanism provided on the top of the metal frame, the clamping mechanism including a clamping box fixedly installed on the top of the metal frame, positioning blocks provided on both sides of the clamping box, the positioning blocks being fixedly connected to the surface of the cover plate, and a limit mechanism provided on both sides of the surface of the cover plate, the limit mechanism being used to linearly limit the tool box.

[0008] Through the above technical solution, the box body serves as the basic frame, providing stable support and space division for the internal parts; the partition enables the fixative to be stored in categories, avoiding crushing and damage; the cover plate and the clamping mechanism work together to facilitate efficient positioning of the tool box, so that the tool box will not affect the storage and retrieval of the fixative, improving the efficiency of use, while the positioning mechanism facilitates the positioning of the metal frame.

[0009] As a further description of the above technical solution: the top and bottom of the inner wall of the clamping box are provided with sliding grooves, and sliders are slidably connected inside the sliding grooves, and abutment blocks are fixedly connected to the inner sides of multiple sliders.

[0010] The above technical solution, which features grooves on the top and bottom of the inner wall of the clamping box, along with a slider and a stop block, has significant advantages. The sliding connection structure of the grooves and sliders allows the stop block to move flexibly, thereby clamping the positioning block and enabling the tool box to be efficiently positioned, making it convenient for users.

[0011] As a further description of the above technical solution: the inner side of the positioning block is provided with a clamping groove for use with the clamping block, and the position where the clamping block contacts the clamping groove is rounded.

[0012] By employing the above technical solution, rounded corners are applied to both the clamping block and the clamping groove, effectively reducing the friction between them and thus improving their service life.

[0013] As a further description of the above technical solution: the front of the clamping box has an opening, and two clamping tubes are fixedly installed on the surface of the inner wall of the clamping box. Each of the two clamping tubes is provided with a compression spring, and a clamping rod is provided on the outside of the two compression springs. The outside of the clamping rod is fixedly connected to the clamping block.

[0014] The above technical solution, through the setting of the clamping tube, facilitates the clamping rod to be clamped by the compression spring when it moves inside, thereby improving the tool box fixing efficiency. The clamping rod drives the clamping block to clamp the clamping groove.

[0015] As a further description of the above technical solution: a square groove is opened on the surface of the clamping tube, and a crossbar is fixedly connected to the surface of the two clamping rods. A rubber block is fixedly connected to the outer side of the crossbar through the square groove and the through-hole.

[0016] The above technical solution, with its two square slots, crossbar, and rubber block, facilitates the movement of the crossbar and clamping rod by pushing the rubber block, thereby making the opening and closing of the toolbox more efficient and improving its usability.

[0017] As a further description of the above technical solution: the limiting mechanism includes a winding box, two winding boxes are fixedly installed on both sides of the inner surface of the cover plate, and a pull rope is movably connected to the winding rod through a damper inside the winding box. The bottom of the pull rope is fixedly connected to the metal frame.

[0018] The above technical solution, through the setting of the winding box, facilitates efficient winding of the pull rope, and the damper and winding rod facilitate stable rotation of the tool box, avoiding instability of the tools placed inside.

[0019] As a further description of the above technical solution: the sum of the heights of the partition and the toolbox is the same as the internal depth of the box.

[0020] By using the above technical solution, and setting the sum of the height of the partition and the toolbox to be the same as the internal depth of the box, the internal space of the box is effectively made more compact, preventing the fixative from shaking and improving the stability and safety of the fixative placement.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the user opens the box, allowing the toolbox to be positioned on top of the cover, thus preventing the toolbox from affecting the fixative stored at the bottom and effectively improving the stability of the internal fixative. By moving the rubber block inward, the crossbar moves the clamping rod inward, compressing the spring. The clamping rod then moves the clamping block out of the clamping groove, opening the toolbox. The toolbox is then slowly moved by the rewind box and pull rope, improving the efficiency and safety of the water quality sampling fixative box.

[0023] 2. In this utility model, by setting the height of the partition and the tool box to be the same as the internal depth of the box, the internal space of the box is effectively made more compact, preventing the fixative from shaking and improving the stability and safety of the fixative placement.

Detailed Implementation

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-5 This utility model provides an embodiment of a water quality fixative preservation device for on-site sampling, comprising: a box body 1, a partition 2 fixedly installed on the inner wall surface of the box body 1, a cover plate 3 movably connected to the top of the box body 1 via a pivot pin, a metal frame 4 movably connected to the inner wall surface of the cover plate 3 via a pivot pin, a tool box 5 fixedly installed on the front of the metal frame 4, a clamping mechanism 6 provided on the top of the metal frame 4, the clamping mechanism 6 including a clamping box 61, the clamping box 61 being fixedly installed on the top of the metal frame 4, and positioning blocks 62 provided on both sides of the clamping box 61. The positioning block 62 is fixedly connected to the surface of the cover plate 3. Limiting mechanisms 7 are provided on both sides of the surface of the cover plate 3. The limiting mechanisms 7 are used to linearly limit the tool box 5. The box body 1 serves as the basic frame, providing stable support and space division for the internal parts. The partition 2 enables the fixative to be stored in categories, avoiding squeezing and damage. The cover plate 3 cooperates with the clamping mechanism 6 to facilitate efficient limiting of the tool box 5, so that the tool box 5 will not affect the storage and retrieval of the fixative, thus improving the efficiency of use. At the same time, the limiting mechanism 7 facilitates the limiting of the metal frame 4.

[0033] Reference Figure 1-5The top and bottom of the inner wall of the clamping box 61 are provided with sliding grooves 63. Sliding sliders 64 are slidably connected inside the sliding grooves 63. Abutting blocks 65 are fixedly connected to the inner side of multiple sliding sliders 64. The design of providing sliding grooves 63 at the top and bottom of the inner wall of the clamping box 61, along with sliding sliders 64 and abutting blocks 65, has significant advantages. The sliding connection structure between the sliding grooves 63 and sliding sliders 64 allows the abutting blocks 65 to move flexibly, thereby clamping the positioning block 62. This enables the tool box 5 to be efficiently limited, making it convenient for users. The inner side of the positioning block 62 is provided with abutting groove 66 that works with the abutting block 65. The contact points between the abutting block 65 and the abutting groove 66 are rounded. By making the abutting block 65 and the abutting groove 66 rounded, the friction between the abutting block 65 and the abutting groove 66 is effectively reduced, thereby improving the service life of the abutting block 65 and the abutting groove 66.

[0034] Reference Figure 1-5 The clamping box 61 has an opening 67 on its front. Two clamping tubes 68 are fixedly installed on the inner wall of the clamping box 61. Each clamping tube 68 has a compression spring 69 inside. A clamping rod 610 is provided on the outside of the two compression springs 69. The outside of the clamping rod 610 is fixedly connected to the clamping block 65. The clamping tubes 68 facilitate the clamping rod 610 to be clamped by the compression spring 69 when it moves inside, thereby improving the clamping efficiency of the tool box 5. The clamping rod 610 drives the clamping block 65 to clamp the clamping groove 66. The surface of the clamping tube 68 has a square groove 611. A crossbar 612 is fixedly connected to the surface of the two clamping rods 610. A rubber block 613 is fixedly connected to the outer side of the square groove 611 and the through-hole 67. The arrangement of the two square grooves 611, the crossbar 612 and the rubber block 613 facilitates the movement of the crossbar 612 and the clamping rod 610 by pushing the rubber block 613, thereby making the opening and closing of the tool box 5 more efficient and improving the efficiency of use. The limiting mechanism 7 includes a winding box 71. Two winding boxes 71 are fixedly installed on both sides of the inner surface of the cover plate 3. The inside of the winding box 71 is movably connected to the winding rod through a damper and a pull rope 72. The bottom of the pull rope 72 is fixedly connected to the metal frame 4. The height of the partition plate 2 and the tool box 5 is the same as the internal depth of the box body 1.

[0035] Working principle: By opening the box 1, the tool box 5 is placed on top of the cover plate 3, thus avoiding any impact on the fixative storage at the bottom and effectively improving the stability of the internal fixative. By moving the rubber block 613 inward, the crossbar 612 drives the clamping rod 610 inward, compressing the spring 69. The clamping rod 610 drives the clamping block 65 to disengage from the inside of the clamping groove 66, thereby opening the tool box 5. It is then slowly moved by the winding box 71 and the pull rope 72, thus improving the efficiency and safety of the water quality sampling fixative box.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
