Description

Technical Field

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

[0002] A water quality analyzer is a specialized instrument used to analyze the content of various components and pollutants in water. Its main purpose is to assess the safety and suitability of water to meet the needs of different fields such as drinking, industry, and agriculture. To facilitate water quality testing, staff often need to collect samples in the field.

[0003] Prior art application number 202123439267.5 discloses a portable water quality tester, which includes: a tester body, a fixing plate on the right side of the tester body, and a first clamping plate on the upper right side of the fixing plate; a squeezing groove located inside the fixing plate, a first spring inside the squeezing groove, a moving plate on the upper end of the first spring, and a second clamping plate fixedly connected to the right side of the moving plate; and an insertion port located inside the fixing plate. The second clamping plate can be fixed by the cooperation of the locking block on the outside of the locking plate and the locking groove inside the insertion port, so that the entire device can be clamped on the arm of the operator.

[0004] However, the above technical solution has some problems: when the detector body is installed on the worker's arm, only one hand can operate it, and it is inconvenient to move the second clamp, making the installation of the detector body inconvenient; and when taking off the detector body, the fixing device connected to the worker's arm needs to be installed and removed together, and repeated use of the detector body may wear and tear on the worker's arm or clothing; if the water quality detector is not removed, the worker needs to lift his arm to monitor the water quality, which can easily cause fatigue to the worker. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a portable water quality analyzer that separates the fixing device from the analyzer body via a fixing plate, and drives the buckle to slide axially along the slide groove B via button A and a transmission mechanism. This facilitates the mounting and dismounting of the analyzer body onto the fixing plate, making the water quality analyzer easy to access. It is simple, efficient, safe, reliable, and easy to operate.

[0006] This utility model is achieved through the following technical solution: a portable water quality analyzer is provided, including an analyzer body and a fixing plate fixed to a human body by a fixing device; the upper and lower sides of the analyzer body are provided with sliding grooves A extending in the vertical direction, and a buckle is slidably disposed in the sliding grooves A; the left side of the analyzer body is provided with a sliding groove B extending in the horizontal direction, and a button A is provided in the sliding groove B and slides along the axis of the sliding groove B; the button A drives the buckle to slide along the axis of the sliding groove A through a transmission mechanism; the upper and lower sides of the fixing plate are provided with slots that are adapted to the buckle; the fixing device is separated from the analyzer body by the fixing plate, and the buckle is driven to slide along the axis of the sliding groove B by the button A and the transmission mechanism, thereby facilitating the mounting and dismounting of the analyzer body on the fixing plate and facilitating the use of the water quality analyzer.

[0007] As an optimization, the transmission mechanism includes a transmission rod A fixed to the buckle and extending axially along the slide groove A. The transmission rod A has a sliding surface A that is inclined towards the button A along the axial direction of the slide groove A. The end of the sliding surface A near the button A is located away from the buckle, and the button A has a sliding surface B that matches the sliding surface A. The button A drives the transmission rod A to move axially along the slide groove A through the sliding surface B on the button A and the sliding surface A on the transmission rod A, thereby driving the buckle to enter and exit the slot, thus facilitating the loading and unloading of the detector body.

[0008] As an optimization, the buckle has a sliding hole A extending axially along the sliding groove A, and a sliding rod A slides inside the sliding hole A. The end of the sliding rod A away from the buckle passes through the return spring A and is connected to the detector body. The sliding rod A and the return spring A ensure that the buckle is firmly locked in the groove and prevent the buckle from falling out of the groove.

[0009] As an optimization, the two ends of the slide bar A are respectively located in the sliding holes A of the upper and lower buckles, and the two ends of the return spring A are respectively connected to the upper and lower buckles; by sharing the return spring A with the upper and lower buckles, costs are saved.

[0010] As an optimization, a sliding groove C extending in the left-right direction is provided on the right side of the detector body, and a button B that slides along the axial direction of the sliding groove C is provided in the sliding groove C; a sliding hole C extending in the left-right direction is provided on the detector body, and a limiting rod is slidably provided in the sliding hole C; the button B drives the limiting rod to slide along the axial direction of the sliding hole C through the transmission rod B, and a limiting hole adapted to the limiting rod is provided on the transmission rod A, and the movement trajectories of the limiting hole and the limiting rod intersect; the position of the transmission rod A is limited by the button B, the transmission rod B and the limiting rod to prevent the buckle from disengaging from the slot.

[0011] As an optimization, the transmission rod B is hinged to the body of the detector, and both ends of the transmission rod B have elongated holes extending along the axial direction of the transmission rod B. Slider blocks are slidably installed in the elongated holes, and the sliders at both ends of the transmission rod B are fixed to the button B and the limiting rod, respectively. Through the transmission rod B, the limiting rod is ensured to move along the axial direction of the slide groove C under the drive of the button B.

[0012] As an optimization, the detector body has a sliding hole B extending in the left and right direction, and a sliding rod B slides inside the sliding hole B. The end of the sliding rod B facing the button B passes through the reset spring B and is fixedly connected to the button B; the sliding rod B and the reset spring B ensure that the button B is reset.

[0013] The beneficial effects of this utility model are as follows: the fixing plate separates the fixing device from the detector body, and the buckle is driven to slide axially along the slide groove B by the button A and the transmission mechanism, thereby facilitating the mounting and dismounting of the detector body on the fixing plate and making it easy to use the water quality detector; the button B, the transmission rod B and the limiting rod limit the position of the transmission rod A to prevent the buckle from disengaging from the slot.

The tester body 1 has vertically extending grooves A on its upper and lower sides, with buckles 4 sliding within the grooves A. The tester body 1 also has a horizontally extending groove B on its left side, with a button A5 sliding along the axis of groove B within the groove B. The button A5 drives the buckles 4 to slide along the axis of groove A via a transmission mechanism 6. The fixing plate 3 has slots 101 on its upper and lower sides that are compatible with the buckles 4. The fixing device 2 is existing technology and can be used with a strap and an adjusting buckle to fix the fixing plate 3 to the human body. Pressing the button A5 causes the buckles 4 to move inward along the axis of groove A. Releasing the button A5 causes the button A5 to move outward along the axis of groove B, and the buckles 4 also move outward along the axis of groove A.

[0020] Fixing plate 3 to the human body via fixing device 2; when the water quality tester needs to be installed on the human body, press button A5 on the left side of the tester body 1.

[0023] Press button A5. Button A5 causes slide surface B501 to move toward slide surface A6011. Under the action of slide surface B501, slide surface A6011 drives transmission rod A601 and buckle 4 to move inward along slide groove A.

[0024] like Figure 1 The buckle 4 shown has a sliding hole A extending axially along the slide groove A. A slide rod A602 slides inside the sliding hole A. The end of the slide rod A602 away from the buckle 4 passes through the return spring A603 and is connected to the detector body 1. The slide rod A602 extends axially along the slide groove A. The sliding hole A is opened on the transmission rod A601.

[0025] Press button A5. Button A5 causes slide surface B501 to move toward slide surface A6011. Under the action of slide surface B501, slide surface A6011 drives transmission rod A601 and buckle 4 to move inward along slide groove A. Slide rod A602 slides in slide hole A, and return spring A603 contracts.

[0026] When button A5 is released, the reset spring A603 relaxes and drives the transmission rod A601 and the buckle 4 to move outward along the slide groove A. The slide rod A602 slides in the slide hole A. Under the action of the slide surface A6011, the slide surface B501 drives button A5 to move outward until button A5 returns to its original position.
