Description

Technical Field

[0001] This utility model belongs to the field of environmental protection technology, and specifically relates to an environmental protection testing instrument. Background Technology

[0002] Environmental monitoring instruments can detect various pollutants in the environment (such as harmful gases in the atmosphere and pollutants in water bodies). They collect data through built-in sensor modules, process the data with the host computer, and display the results on the screen, providing quantitative basis for environmental monitoring.

[0003] In this existing design, the connecting straps for portable wear are mostly of fixed length or have cumbersome adjustment methods, making it difficult to adapt to different users' wrists, necks, and other wearing parts. This results in poor wearing comfort and low versatility. At the same time, the connecting straps lack an orderly storage structure and are prone to tangling when not in use. This not only affects the cleanliness of the device but may also damage the connecting straps due to tangling and pulling, shortening their service life.

[0004] Therefore, an environmental protection testing instrument was designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an environmental protection testing instrument. This device adjusts and fixes the length of the flexible connecting strap by pulling it out and locking it with a rotating positioning block, adapting to different wearing scenarios. A spring-loaded mechanism works in conjunction with the connecting strap winding post to automatically retract the connecting strap, eliminating manual handling steps, reducing operational steps, and improving efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmental protection detector, comprising a detector main unit housing and a flexible connecting strip, wherein an end connecting housing is provided on the surface of the detector main unit housing, a connecting strip placement groove is provided on the surface of the end connecting housing, a connecting strip winding post is provided on the surface of the end connecting housing, the connecting strip winding post is fixedly connected to the end connecting housing through the connecting strip placement groove, the flexible connecting strip is wound around the surface of the connecting strip winding post, one end of the flexible connecting strip away from the connecting strip winding post is fixedly connected to the surface of the end connecting housing, and a connecting strip limiting groove that cooperates with the flexible connecting strip is provided on the surface of the end connecting housing.

[0007] As a preferred embodiment of the environmental protection testing instrument of this utility model, a spring is wound around the surface of the connecting belt winding column, and the two ends of the spring are fixedly connected to the connecting belt winding column and the flexible connecting belt, respectively.

[0008] In a preferred embodiment of this utility model of an environmental protection testing instrument, the end connecting housing is disposed at the bottom end of the main housing of the testing instrument.

[0010] As a preferred embodiment of the environmental protection testing instrument of this utility model, the rotating positioning block is fixedly connected to an anti-slip rubber pad on the side near the flexible connecting belt.

[0011] As a preferred embodiment of the environmental protection detector of this utility model, the surface of the detector main body housing is provided with a connecting shell mounting groove that cooperates with the end connecting shell, the surface of the detector main body housing is symmetrically provided with locking blocks, the surface of the detector main body housing is provided with a block guide groove that cooperates with the locking blocks, the surface of the end connecting shell is provided with a locking slot that cooperates with the locking blocks, and a compression spring is fixedly connected to the end of the locking block away from the end connecting shell.

Detailed Implementation

[0025] 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 scope of protection of the present utility model. Embodiment 1

[0026] like Figure 1 As shown;

[0027] An environmental protection testing instrument includes a main unit housing 1 and a flexible connecting belt 2.

[0028] In this implementation plan: In the prior art, the main body housing 1 of the detector is used to detect various pollutants in the environment. However, in this prior design, the portable connecting strap is mostly of fixed length or has a cumbersome adjustment method, which is difficult to adapt to different users' wrists, necks and other wearing parts, resulting in poor wearing comfort and low versatility. At the same time, the connecting strap lacks an orderly storage structure and is prone to messy tangling when not in use. This not only affects the cleanliness of the device, but may also damage the connecting strap due to tangling and pulling, shortening its service life. In terms of use, this problem is obviously a real and difficult problem to solve.

[0029] This application incorporates the aforementioned prior art, such as Figures 1 to 6 As shown:

[0030] Based on the above: An environmental protection detector has an end connection housing 3 on the surface of the main housing 1. The end connection housing 3 has a connecting strip placement groove 31 on its surface and a connecting strip winding post 32 on its surface. The connecting strip winding post 32 is fixedly connected to the end connection housing 3 through the connecting strip placement groove 31. A flexible connecting strip 2 is wound around the surface of the connecting strip winding post 32. The end of the flexible connecting strip 2 away from the connecting strip winding post 32 is fixedly connected to the surface of the end connection housing 3. The end connection housing 3 has a connecting strip limiting groove 21 that cooperates with the flexible connecting strip 2 on its surface.

[0031] In this implementation scheme: the main housing 1 of the detector is the main structure. The connecting strap winding post 32 is fixed to the end connecting housing 3 via the connecting strap placement groove 31. The flexible connecting strap 2 is wound around the surface of the connecting strap winding post 32, with one end fixed to the end connecting housing 3 and the other end freely retractable. When it needs to be hung on the wrist or neck, the free end of the flexible connecting strap 2 is pulled out to release it from the connecting strap winding post 32. The length increases with the pulling distance. The connecting strap limiting groove 21 matches the shape of the flexible connecting strap 2, realizing length adjustment while keeping the flexible connecting strap 2 neat during recycling. The main housing 1 of the detector is the core load-bearing structure. The structure features a connecting strip placement groove 31 on the surface of the end connecting housing 3, which provides an installation reference for the connecting strip winding post 32. The flexible connecting strip 2 is spirally wound and stored on the surface of the connecting strip winding post 32. The end away from the winding post is fixed to the surface of the end connecting housing 3. The connecting strip limiting groove 21 on the surface of the end connecting housing 3 matches the shape of the flexible connecting strip 2, ensuring that the flexible connecting strip 2 remains neat when pulled out and retracted, avoiding messy tangling. The length of the flexible connecting strip 2 can be flexibly changed by pulling it out to fit different wearing parts such as the wrist and neck, meeting the body shape differences of different users and improving the fit and convenience of wearing.

[0032] Furthermore:

[0033] like Figure 3 As shown:

[0034] In an optional embodiment, a spring 33 is wound around the surface of the connecting strip winding post 32, and the two ends of the spring 33 are fixedly connected to the connecting strip winding post 32 and the flexible connecting strip 2, respectively.

[0035] In this embodiment: the spring 33 is wound around the surface of the connecting strip winding post 32, and its two ends are fixed to the connecting strip winding post 32 and the flexible connecting strip 2 respectively. When the flexible connecting strip 2 is pulled, the spring 33 is stretched and stores force. After the connecting strip is released, the spring 33 releases its elastic potential energy, which drives the connecting strip winding post 32 to rotate in the opposite direction, automatically winding and retracting the flexible connecting strip 2 to achieve reset. The elasticity of the spring 33 is used to achieve automatic reset of the flexible connecting strip 2, eliminating the need for manual adjustment and reducing operation steps.

[0036] Furthermore:

[0037] like Figure 1 As shown:

[0038] In an optional embodiment, the end connection housing 3 is disposed at the bottom end of the detector main housing 1.

[0039] In this embodiment: the end connecting housing 3 is located at the bottom of the detector main housing 1. The flexible connecting strap 2 is pulled out and extended from the connecting strap winding post 32 at the bottom. When used as a wristband, the connecting strap is fixed around the wrist from the bottom of the detector main housing 1, with the display screen of the detector main housing 1 facing upwards and the flexible connecting strap 2 located below the wrist, without obstructing the view. When used as a neckband, the flexible connecting strap 2 extends from the bottom towards the neck, with the display screen of the detector main housing 1 facing the user, and the flexible connecting strap 2 avoids the view of the display screen. Whether used as a wristband or a neckband, the extension direction of the flexible connecting strap 2 avoids the display screen area, so it does not affect the user's viewing of the display screen of the detector main housing 1, improving the synchronization of operation and observation.

[0040] Furthermore:

[0041] like Figure 3 As shown:

[0042] In an optional embodiment, a rotating positioning block 4 is rotatably connected to the surface of the end connecting housing 3, a positioning block clearance groove 41 is provided on the surface of the end connecting housing 3, and a positioning spring 42 is fixedly connected to the surface of the rotating positioning block 4.

[0043] In this embodiment: the rotating positioning block 4 is rotatably connected to the surface of the end connecting housing 3, and the positioning block clearance groove 41 provides it with rotation space. When the flexible connecting strip 2 is pulled to the required length, the positioning spring 42 provides pressure, which drives the rotating positioning block 4 to rotate around the pin and press against the surface of the flexible connecting strip 2, pressing the connecting strip between the end connecting housing 3 and the rotating positioning block 4. The movement of the connecting strip is restricted by friction, and the length is fixed. Rotating the rotating positioning block 4 in the opposite direction releases the pressure, and the length can be adjusted again. Through the pressing action of the rotating positioning block 4, the length of the flexible connecting strip 2 is accurately fixed, avoiding length changes due to shaking during use.

[0044] Furthermore:

[0045] In an optional embodiment, the rotating positioning block 4 is fixedly connected to an anti-slip rubber pad on the side near the flexible connecting strip 2.

[0046] In this embodiment: the rotating positioning block 4 is fixed with an anti-slip rubber pad on the side close to the flexible connecting strip 2. When the rotating positioning block 4 presses the connecting strip, the texture of the rubber pad surface contacts the surface of the flexible connecting strip 2. By increasing the friction of the contact surface, the locking effect on the connecting strip is enhanced, preventing the flexible connecting strip 2 from sliding under pressure.

[0047] Furthermore:

[0048] like Figure 4 As shown:

[0049] In an optional embodiment, the surface of the main housing 1 of the detector is provided with a connecting shell mounting groove 34 that mates with the end connecting housing 3. The surface of the main housing 1 of the detector is symmetrically provided with locking blocks 5. The surface of the main housing 1 of the detector is provided with a block guide groove 51 that mates with the locking blocks 5. The surface of the end connecting housing 3 is provided with a locking groove 52 that mates with the locking blocks 5. A compression spring 53 is fixedly connected to the end of the locking block 5 away from the end connecting housing 3.

[0050] In this embodiment: the connecting shell mounting groove 34 on the surface of the detector main housing 1 provides a mounting position for the end connecting housing 3. The locking block 5 is embedded in the block guide groove 51. The compression spring 53 pushes the locking block 5 out. When the end connecting housing 3 is installed, the locking groove 52 on its surface is aligned with the locking block 5. The locking block 5 is embedded in the locking groove 52, and the end connecting housing 3 is fixedly connected to the detector main housing 1.

[0051] Furthermore:

[0052] like Figure 5 and Figure 6 As shown:

[0053] In an optional embodiment, the locking block 5 is sloped on the side near the end connecting housing 3.

[0054] In this embodiment, the side of the locking block 5 near the end connecting housing 3 is set as an inclined surface. When the end connecting housing 3 is inserted into the connecting housing mounting groove 34, its edge first contacts the inclined surface of the locking block 5. The inclined surface guides the end connecting housing 3 to squeeze the locking block 5, so that the locking block 5 compresses the compression spring 53 and retracts into the block guide groove 51 until the locking groove 52 is aligned with the locking block 5. The locking block 5 pops out to complete the connection. The inclined surface design provides guidance for the connection between the end connecting housing 3 and the main housing 1 of the detector. The installation can be completed without manual operation of the locking block 5, simplifying the connection steps and improving assembly efficiency.

[0055] Furthermore:

[0056] like Figure 5 and Figure 6 As shown:

[0057] In an optional embodiment, an auxiliary limiting slider 6 that cooperates with the locking block 5 is slidably connected to the inner surface of the end connecting housing 3. A slider linkage push post 7 is fixedly connected to the surface of the auxiliary limiting slider 6. A slider operation lever 8 that cooperates with the slider linkage push post 7 is slidably connected to the surface of the end connecting housing 3. A slider movement guide groove 9 that cooperates with the auxiliary limiting slider 6 and the slider linkage push post 7 is provided on the surface of the end connecting housing 3.

[0058] In this embodiment: the auxiliary limiting slider 6 is slidably connected to the end connecting housing 3, and is connected to the slider operation lever 8 through the slider linkage push post 7. The slider movement guide groove 9 restricts the sliding trajectory of the three. When it is necessary to disassemble the end connecting housing 3, push the slider operation lever 8 to drive the slider linkage push post 7 and the auxiliary limiting slider 6 to slide. The auxiliary limiting slider 6 squeezes the locking block 5, causing it to disengage from the locking slot 52, so that the end connecting housing 3 can be detached from the main housing 1 of the detector. The transmission structure driven by the slider operation lever 8 can quickly release the lock and realize the disassembly of the end connecting housing 3. This makes it convenient to use the main housing 1 of the detector alone when the flexible connecting strip 2 is not needed, thus improving the multi-functionality of the instrument.

[0059] Furthermore:

[0060] like Figure 6 As shown:

[0061] In an optional embodiment, two sets of auxiliary limiting sliders 6, slider linkage push pins 7, and slider operation levers 8 are symmetrically arranged.

[0062] In this embodiment, two sets of auxiliary limiting sliders 6, slider linkage push pins 7, and slider operation levers 8 are symmetrically arranged, corresponding to the locking blocks 5 on both sides respectively. When disassembling the end connecting housing 3, the slider operation levers 8 on both sides must be pressed simultaneously to drive the two sets of auxiliary limiting sliders 6 to simultaneously squeeze the locking blocks 5 on both sides, causing them to disengage from the locking slots 52. Pressing only one lever cannot unlock the lock. The design of simultaneous operation on both sides avoids accidental disassembly of the end connecting housing 3 due to accidental contact with one side of the slider operation lever 8, prevents the detector main housing 1 from falling and being damaged, and improves the safety of use.

[0063] Working principle: The end connecting housing 3 is aligned with the connecting housing mounting groove 34 and pushed in. The edge of the end housing first contacts the inclined surface of the locking block 5. The inclined surface decomposes the pushing force into a component force perpendicular to the guide groove 51 of the locking block, forcing the locking block 5 to compress the compression spring 53 and slide inward along the guide groove to retract. The end housing is continuously pushed in until the locking groove 52 on its surface is aligned with the locking block 5. The compression spring 53 releases its potential energy, pushing the locking block 5 to slide outward and embed into the locking groove 52, completing the mechanical locking of the end connecting housing 3 and the main housing 1 of the detector. When it is necessary to adjust the length of the flexible connecting strip 2, press the rotating positioning block 4 to make the rotation... The positioning surface of the rotating positioning block 4 is disengaged from the surface of the flexible connecting strip 2. Then, the free end of the flexible connecting strip 2 is manually pulled outward. The flexible connecting strip 2 rotates and slides along the surface of the connecting strip winding post 32, thereby causing the spring 33 wound on the surface of the connecting strip winding post 32 to be further twisted and deformed with the rotation. The flexible connecting strip 2 is gradually released from the connecting strip winding post 32, and its length increases with the increase of the pulling distance. Its surface slides along the connecting strip placement groove 31 of the end connecting housing 3 until the appropriate wearing length is reached. When the connecting strip length is appropriate, the pulling is stopped, the rotating positioning block 4 is released, and the rotating positioning block 4 is positioned by the positioning spring. Under the elastic force of spring 42, the flexible connecting belt rotates around the pin axis in the direction of the connecting belt. The anti-slip rubber pad on its surface gradually adheres to the surface of the flexible connecting belt 2. The positioning spring 42 continuously applies pressure, making the anti-slip rubber pad in close contact with the surface of the connecting belt. The friction force restricts the sliding of the connecting belt. After use, the positioning block 4 is manually rotated in the opposite direction to overcome the elastic force of the positioning spring 42. The anti-slip rubber pad is removed from the surface of the flexible connecting belt 2, releasing the friction constraint. The spring 33 releases the stored elastic potential energy, driving the flexible connecting belt 2 to gradually spiral back along the surface of the connecting belt winding post 32. During the recovery process, the flexible connecting belt 2 follows the connecting belt limiting groove 21. The guide function neatly stores the material, eventually wrapping it completely around the surface of the winding column and restoring it to its initial stored state. When the flexible connecting strip 2 is not needed, both hands simultaneously pinch the slider operation levers 8 on both sides of the end connecting housing 3, driving the slider linkage push column 7 and auxiliary limit slider 6 to slide. The auxiliary limit slider 6 squeezes the locking block 5, causing it to disengage from the locking slot 52, thus detaching the end connecting housing 3 from the main housing 1 of the detector. After the lock is released, pull the end connecting housing 3 outwards, causing it to slide out along the connecting housing mounting slot 34, completing the separation from the main housing 1 of the detector. At this time, the main housing 1 of the detector can be used alone for detection operations.
