Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, specifically a foldable environmental monitoring handheld device. Background Technology

[0002] In environmental monitoring, ecological patrols, emergency law enforcement, and scientific sampling, portable testing equipment is often required to conduct on-site measurements of the surrounding environment, including air, water, and soil. To ensure data accuracy and operational standardization, testing instruments typically need to be placed stably at a specific height or away from human interference. Traditional methods often rely on tripods for direct operation: while offering good stability, these tripods are large, heavy, and cumbersome to deploy, making them unsuitable for foot patrols, confined spaces, or rapid response scenarios.

[0003] However, existing handheld supports generally have significant shortcomings: some products use a simple telescopic rod structure, lack a reliable folding and locking mechanism, and are prone to shaking after unfolding, failing to form rigid support; others, although they have folding functions, rely on magnetic attraction, buckles or ball bearings for positioning, which have problems such as insecure locking, easy disengagement due to vibration, and vague operation feel, making it difficult to work stably in complex outdoor environments. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable environmental monitoring handheld device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable environmental monitoring handheld device, including an outer rod; a flipping assembly, disposed at the bottom of the outer rod, including a rotating shaft, rotatably disposed on one side of the bottom of the outer rod; and a telescopic assembly, disposed inside the outer rod, including an inner rod, which slides up and down inside the outer rod.

[0006] As a further description of the above technical solution:

[0007] The flipping assembly includes: a handle, rotatably mounted at one end of the bottom of the outer rod, with its top end rotatably mounted on the outer wall of the rotating shaft; a limiting plate, mounted on both sides of the bottom end of the outer rod; a spring pin, horizontally sliding on both sides inside the top end of the handle; a compression spring, mounted on both sides inside the top end of the handle, with one end welded to the spring pin; and a sliding groove, formed on the side of the two limiting plates near the middle of the outer rod.

[0008] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:

[0011] The limiting plate has a semi-circular structure.

[0012] As a further description of the above technical solution:

[0013] The end of the spring pin furthest from the compression spring is a conical head.

[0014] As a further description of the above technical solution:

[0015] The sliding groove is arc-shaped, and there are snap-fit ​​grooves at both ends, with the conical head of the spring pin snapped into the snap-fit ​​groove.

[0016] As a further description of the above technical solution:

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, this embodiment provides a foldable environmental monitoring handheld device, including: an outer rod 1; a flipping component 2, disposed at the bottom of the outer rod 1, including a pivot 22, rotatably disposed on one side of the bottom of the outer rod 1; and a telescopic component 3, disposed inside the outer rod 1, including an inner rod 31, which slides up and down inside the outer rod 1.

[0032] In this embodiment, the flipping component 2 and the telescopic component 3 constitute a foldable environmental monitoring handheld device according to this application.

[0033] It should also be noted that the environmental monitoring in this application can include atmospheric environmental monitoring, rapid on-site water quality monitoring, and measurement of meteorological and microenvironmental parameters, etc. Figure 1 In this embodiment, subject A is used as an example for description. Of course, other types of atmospheric environment detection can also adopt a similar structure, which will not be described in detail below.

[0034] Furthermore, in this embodiment, the outer rod 1 is made of 6061 aluminum alloy, which is wear-resistant and corrosion-resistant; the flipping component 2 is rotatably connected to the bottom of the outer rod, and when folded, the handle can be parallel to the outer rod, shortening the storage length; the inner rod 31 of the telescopic component 3 is made of the same aluminum alloy. Using a foldable handle as the gripping carrier, the outer rod and inner rod form a telescopic support structure, and the testing equipment is fixed via a top connecting seat; when stored, the inner rod retracts into the outer rod, the handle rotates 180 degrees around the pivot and locks, achieving miniaturized storage of the handheld device; when in use, the handle unfolds and locks to provide a stable grip, and the inner rod stretches to the target length according to the testing height requirements and is fixed, ensuring the testing equipment is in the ideal testing position. The folded length is shortened, allowing it to be easily placed in a backpack; the overall structure has stable load-bearing capacity, ensuring accurate testing data after the testing equipment is installed.

[0035] Example 2:

[0036] Based on Embodiment 1, in order to provide a grip storage function, a flip assembly 2 is provided at the bottom of the outer rod 1.

[0037] Specifically, the flipping assembly 2 includes: a handle 21, rotatably disposed at one bottom end of the outer rod 1, and with its top end rotatably mounted on the outer wall of the rotating shaft 22; limiting discs 23, disposed on both sides of one bottom end of the outer rod 1; spring pins 24, horizontally sliding on both sides inside the top end of the handle 21; compression springs 25, disposed on both sides inside the top end of the handle 21, with one end welded to the spring pins 24; and sliding grooves 26, formed on the side of the two sets of limiting discs 23 near the middle of the outer rod 1.

[0038] In this embodiment, the handle 21 is a composite structure of engineering plastic and rubber, with the main body being ABS plastic; the pivot 22 is made of stainless steel; the limiting plate 23 is a semi-circular stainless steel sheet; and the spring pin 24 is made of carbon steel with a conical head for easy engagement. In the unfolded state, the conical head of the spring pin 24 is engaged in the unfolding engagement groove of the sliding groove 26 under the action of the compression spring 25, with the handle perpendicular to the outer rod, providing a stable grip. During folding, an external force is applied to overcome the spring force of the compression spring, causing the conical head of the spring pin to disengage from the unfolding engagement groove and slide along the arc-shaped sliding groove 26. When the handle is rotated 180 degrees, the spring pin reaches the folding engagement groove at the end of the sliding groove, the compression spring resets, and pushes the conical head into place, completing the folding lock. The anti-slip rubber handle prevents hand slippage during testing; the conical head of the spring pin facilitates engagement and disengagement.

[0039] Example 3:

[0040] Based on Embodiment 2, in order to provide a length adjustment function, a telescopic component 3 is provided inside the outer rod 1.

[0041] Specifically, the telescopic component 3 includes: a pressure block 32, which is rotatably disposed on the outer walls of both ends of the top of the outer rod 1; a locking block 33, which is disposed on one end of the pressure block 32; a compression spring 34, which is disposed on the other end of the pressure block 32 and located on the inner wall of the outer rod 1; and a locking groove 35, which is opened on both sides of the outer wall of the inner rod 31, and multiple sets are opened vertically, and the locking block 33 is engaged in the locking groove 35.

[0042] In a preferred embodiment, the pressure block 32 is made of ABS plastic with an anti-slip pressing surface at one end; the locking block 33 is made of nylon; the compression spring 34 is a stainless steel compression spring; and the locking groove 35 is a rectangular groove vertically distributed along the outer walls of both sides of the inner rod. When stretching the inner rod, pressing the pressure blocks 32 on both sides causes the pressure blocks to rotate around the pivot point and compress the compression spring 34, causing the locking block 33 to disengage from the current locking groove 35 along with the pressure block. The inner rod is then stretched upwards to the target height, aligning the corresponding locking groove with the locking block. Releasing the pressure block causes the compression spring to reset, pushing the pressure block to rotate, and the locking block engages in the locking groove, thus fixing the length of the inner rod. During retraction, the pressing operation is repeated to push the inner rod back into the outer rod, and the locking block engages in the top locking groove for storage. Multiple locking grooves allow the inner rod to be adjusted to different heights, adapting to various multi-position detection needs; the nylon locking block and the aluminum alloy inner rod are wear-resistant and provide stable tension.

[0043] Example 2:

[0044] Based on Embodiment 1, in order to provide a grip storage function, a flip assembly 2 is provided at the bottom of the outer rod 1.

[0045] Specifically, a testing equipment connecting seat is provided at the top of the inner rod 31, and the testing equipment can be connected to the connecting seat by bolts.

[0046] In this embodiment, the detection equipment connecting seat at the top of the inner rod 31 is a circular metal disc with threaded holes on its surface, which can be adapted to the mounting holes of most small detection equipment; the connecting seat is welded and fixed to the top of the inner rod.

[0047] When installing the testing equipment, align the mounting holes on the bottom of the equipment with the threaded holes of the connector and secure it with bolts. During the testing process, the rigid connection of the connector ensures that the equipment does not shake, thus ensuring accurate data acquisition by the sensor.

[0048] In actual use, when the user first puts away the handheld holder, the user disassembles the detection device from the top connecting seat of the inner rod 31, and then presses the pressure blocks 32 on both sides. The pressure blocks 32 press the compression spring 34 to compress, and the pressure blocks 32 rotate and drive the locking block 33 to disengage from the bottom set of locking grooves 35. Then the user slides the inner rod 31 into the outer rod 1. When the top locking groove 35 coincides with the position of the locking block 33, the user releases the pressure block 32, the compression spring 34 resets and pushes the pressure block 32 to rotate, and the locking block 33 locks the inner rod 31 in the top set of locking grooves 35. Next, the user flips the handle 21 upwards by 180 degrees. The user initially applies a greater force than the compression spring 25, causing the conical head of the spring pin 24 to slide on one side of the sliding groove 26, unfolding the locking groove and disengaging. As the handle 21 flips, the spring pin 24 slides within the sliding groove 26 until the conical head of the spring pin 24 reaches the folded locking groove at the other end of the sliding groove 26. The compression spring 25 then resets, pushing the conical head of the spring pin 24 to engage in the folded locking groove at the other end of the sliding groove 26.

[0049] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
