Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection, in particular to a water conservancy water quality detection board which is convenient for placing a test strip. Background Art
[0002] The detection reagent is a simple, rapid, easy-to-popularize and on-site diagnostic technology. It is widely used in many fields due to its advantages of not being limited by instruments, easy operation, and timely and accurate result reporting. It is also often used in water quality testing projects around water conservancy facilities.
[0003] Since most reagent tests use absorbent materials such as paper as carriers, in order to prevent the test paper from moving when the reagent is added, the test paper needs to be fixed. In the prior art, most of them are done by setting a cover plate to press on the test paper, and opening a notch in the cover plate, and the reagent is dripped onto the test paper through the notch. However, this method reduces the available area of the test paper, and the cover plate will also affect the diffusion of the reagent on the test paper. In view of this, we propose a hydraulic water quality testing board that is convenient for placing test strips. Utility Model Content
[0004] The main purpose of the utility model is to provide a water conservancy and water quality detection board which is convenient for placing test strips, and can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A water conservancy water quality detection plate for accommodating test strips comprises a detection plate, wherein two fixed blocks symmetrically distributed frontward and rearward are installed at the lower end of the detection plate, and two groups of slide rails are installed at the lower end of the detection plate, each group of the slide rails is provided with two slide rails, and the two slide rails are symmetrically distributed leftward and rightward with the fixed block as the center, a sliding sleeve is slidably sleeved on the outer surface of the slide rail, a connecting frame is installed on the side of the upper end of the sliding sleeve away from the fixed block, an L-shaped curved rod is rotatably connected inside the connecting frame, the lower left end and the lower right end of the fixed block are rotatably connected to electric cylinders, the movable end of the electric cylinder is rotatably connected to the L-shaped curved rod, and a pressing rod is movably connected between the two L-shaped curved rods symmetrical frontward and rearward.
[0007] Preferably, a recessed area is provided at the upper end of the detection plate.
[0008] Preferably, a rubber sleeve is fixedly sleeved on the outer surface of the pressing rod.
[0009] Preferably, two T-shaped plates are installed at the lower end of the fixing block.
[0010] Preferably, one end of the electric cylinder close to the fixed block is rotatably connected to the T-shaped plate.
[0011] Preferably, two notches are provided at the left and right ends of the detection plate, and the notches are located directly above the slide rails.
[0012] Preferably, the connecting frame is located just outside the notch, and the width of the connecting frame is not greater than the width of the notch.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The test paper is fixed by setting two pressing rods to cooperate with each other. First, the active end of the electric cylinder is extended and drives the L-shaped curved rod to rotate toward the direction close to the detection plate, so that the pressing rod is pressed on the test paper. Then the active end of the electric cylinder continues to extend. Since the L-shaped curved rod cannot continue to rotate, the L-shaped curved rod drives the connecting frame to move along the axial direction of the slide rail, so that the pressing rod moves horizontally in the direction away from the test paper, flattening the test paper to facilitate the addition of reagents;
[0015] 2. Use two pressing rods to press the two ends of the test paper to minimize the obstruction of the test paper by the pressing rods, making it easier to add more reagents to the test paper. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] like Figure 1-Figure 5 As shown, a water conservancy and water quality detection plate for accommodating test strips comprises a detection plate 1, wherein two fixed blocks 2 symmetrically distributed front and back are installed at the lower end of the detection plate 1, and two groups of slide rails 8 are installed at the lower end of the detection plate 1, each group of the slide rails 8 is provided with two, and the two slide rails 8 are symmetrically distributed left and right with the fixed block 2 as the center, and a slide sleeve 7 is slidably sleeved on the outer surface of the slide rail 8, and a connecting frame 6 is installed on the side of the upper end of the slide sleeve 7 away from the fixed block 2, and an L-shaped curved rod 4 is rotatably connected inside the connecting frame 6, and the lower left end and the lower right end of the fixed block 2 are both rotatably connected to the electric cylinder 3, and the movable end of the electric cylinder 3 is rotatably connected to the L-shaped curved rod 4, and a pressing rod 5 is movably connected between the two L-shaped curved rods 4 symmetrical front and back.
[0026] In the initial state, the two pressing rods 5 are away from the detection plate 1, and the two pressing rods 5 are staggered up and down. When performing detection, the test paper is first placed on the detection plate 1, and then the two groups of electric cylinders 3 are started in sequence. The active end of the electric cylinder 3 extends and drives the L-shaped curved rod 4 to rotate toward the detection plate 1, so that the pressing rod 5 is pressed on the test paper. Then the active end of the electric cylinder 3 continues to extend. Since the L-shaped curved rod 4 cannot continue to rotate, the L-shaped curved rod 4 drives the connecting frame 6 to move axially along the slide rail 8, so that the pressing rod 5 moves horizontally in the direction away from the test paper to flatten the test paper.
[0027] In order to prevent the test paper from being separated from the detection plate 1 when the test paper is placed, in this embodiment, a recessed area 11 is provided at the upper end of the detection plate 1 to limit the movement range of the test paper.
[0028] In order to increase the friction between the pressing rod 5 and the test paper, in this embodiment, a rubber sleeve 51 is fixedly sleeved on the outer surface of the pressing rod 5. Utilizing the deformable property of the rubber sleeve 51, when the pressing rod 5 contacts the test paper, the rubber sleeve 51 is deformed, thereby increasing the contact area with the test paper.
[0029] Specifically, two T-shaped plates 21 are installed at the lower end of the fixing block 2 ; and one end of the electric cylinder 3 close to the fixing block 2 is rotatably connected to the T-shaped plate 21 .
[0030] Specifically, two notches 12 are provided at the left and right ends of the detection plate 1 , and the notches 12 are located directly above the slide rail 8 ; the connecting frame 6 is located directly outside the notches 12 , and the width of the connecting frame 6 is not greater than the width of the notches 12 .
