[0034] The utility model is further described below in conjunction with embodiments.

[0035] Example

[0036] Combination Figures 1 to 5 , a water quality monitor for environmental engineering in this embodiment includes a detection box 1 and a sample bottle 5. The detection box 1 has a receiving slot for placing the sample bottle 5, and a detector for detecting the water quality in the sample bottle 5. The detection box 1 has an openable cabinet cover 2, and the cabinet cover 2 has a display screen 3 and operation buttons 4. The specific structural design and detection process of the detection box 1 and the sample bottle 5 belong to the well-known technology in the industry and will not be repeated here. It should be noted that generally, the sample bottle 5 can be directly placed in the receiving slot, but the slot depth is not very deep, and the width exceeds the size of the sample bottle 5. The stability of the sample bottle 5 after placement is not high. This embodiment further optimizes how to achieve stable placement of the sample bottle 5.

[0037] Specific as Figure 2-Figure 4 As shown, in this embodiment, a limiting assembly 6 for limiting the shaking of the sample bottle 5 in the receiving groove is further provided between the sample bottle 5 and the detection box 1; the limiting assembly 6 includes a groove 62 extending inwardly on the outer wall surface of the lower part of the sample bottle 5, and a limiting rod 63 slidably arranged on the inner wall of the receiving groove, the limiting rod 63 extends in a direction close to or away from the groove 62, and the tail end of the limiting rod 63 is connected to the first spring 64; the front end of the limiting rod 63 can be driven inwardly to fit into the groove 62 at the lower part of the sample bottle 5, and at this time, the tail end of the limiting rod 63 extends beyond the groove 62. The clamping and fixing of the sample bottle 5 is achieved by the clamping and fitting of the limiting rod 63 and the groove 62, which can effectively prevent the sample bottle 5 from shaking in the receiving groove.

[0038] More precisely, combined with Figure 4 A limiting groove 61 is provided on the inner wall of the receiving groove for placing the sample bottle 5. The limiting groove 61 extends in the horizontal direction, and along the direction close to the sample bottle 5, a first spring 64 and a limiting rod 63 are sequentially installed in the limiting groove 61. One end of the first spring 64 is fixed on the inner wall of the limiting groove 61, and the other end is fixed on the tail end of the limiting rod 63; the limiting rod 63 slides in the limiting groove 61; and preferably, the front end wall of the limiting rod 63 facing the groove 62 is provided with an arc-shaped guide wall, so as to facilitate flexible embedding in the groove 62. A slide groove 65 communicating with the outside is provided above the limiting groove 61, that is, a slide groove 65 communicating with the inner cavity of the detection box 1, and a stop block 66 extending toward the slide groove 65 is provided on the upper part of the limiting rod 63. The sliding of the limiting rod 63 in the limiting groove 61 can be controlled by pushing the stop block 66 back and forth. As Figure 4As shown in the figure, with the left side as the front and the right side as the rear, pushing the block 66 to the left drives the limiting rod 63 to the left until it is embedded in the groove 62. At this time, the first spring 64 can be in an elastic reset state or a compressed state. When it is in a compressed state, it can further enhance the clamping effect and have a pre-tightening force. When the sample bottle 5 needs to be taken out, pushing the block 66 to the right drives the limiting rod 63 to the right until it is out of the groove 62. At this time, the sample bottle 5 can be taken out, and the first spring 64 is in a further compressed state. Release the block 66 to automatically reset.

[0039] In order to improve the convenience of controlling the stopper 66, the limiting assembly 6 further includes a stopper rod 67 mounted in the slide groove 65, the stopper rod 67 slides up and down in the slide groove 65 and contacts with the upper surface of the stopper 66, and the wall surfaces of the stopper rod 67 and the stopper 66 are wedge-shaped wall surfaces adapted to the inclined direction, such as Figure 4 As shown, the bottom slope of the push rod 67 gradually increases in height from left to right, and the upper surface of the push block 66 also gradually increases in height from left to right, and the upper surface of the push block 66 has a smooth wall surface that abuts against the bottom surface of the push rod 67, and the push rod 67 is gradually pressed downward, so that its bottom surface gradually contacts the push block 66, and the push rod 67 is continuously pressed downward. With the cooperation of the wedge-shaped wall surface, the displacement of the push block 66 in the length direction of the limiting groove 61 can be controlled, and finally the limiting rod 63 is driven to move inward in the horizontal direction, realizing the effect of contracting and squeezing the first spring 64, so that the limiting rod 63 can be separated from the groove 62; on the contrary, the push rod 67 is lifted or there is no need to lift it, and the limiting rod 63 can automatically slide in the reverse direction to the reset state under the reset action of the first spring 64, that is, it reaches the state position originally embedded in the groove 62. By setting the push rod 67, the horizontal forward and backward pushing action is converted into the up and down pressing action control, which is more convenient for the operator to operate in the inner cavity of the detection box 1, and it is also more labor-saving and saves operating space, and the convenience is significantly improved.

[0040] Furthermore, in order to further improve the convenience of operation, a ring 68 is fixedly connected to the top wall of the rod 67. The ring 68 surrounds the outer circumference of the sample bottle 5, and a certain gap is maintained between the ring 68 and the outer wall of the sample bottle 5. Pressing the ring 68 downward can drive the horizontal displacement of the limiting rod 63. The ring 68 can also serve as a preliminary guide for placing the sample bottle 5 into the receiving groove. In practice, the limiting components 6 can be set on both sides of the sample bottle 5 and symmetrically distributed on both sides of the sample bottle 5. In this way, the two groups of rods 67 are fixedly installed on the same group of rings 68. Pressing the ring 68 downward can simultaneously realize the operation of the rods 67 on both sides, which is faster and more convenient. The annular ring 68 is also easier for operators to grasp and operate, and the operation feels more comfortable.

[0041] Furthermore, in order to achieve heat dissipation of the detection box 1, a heat dissipation channel connecting the inner cavity of the box and the outside is also provided on the wall of the detection box 1, and a heat dissipation component 7 is also provided on the side wall of the detection box 1. In conventional technology, a radiator is generally directly arranged on the side wall of the detection box 1. This embodiment is further optimized, and the heat dissipation component 7 includes a connecting plate 71 fixedly mounted on the side wall of the detection box 1, and a radiator 72 movably inserted on the connecting plate 71. That is, the traditional radiator 72 is adjusted from a fixed installation type to a movable installation type, which is convenient for installation, replacement and maintenance. The connecting plate 71 can be fixed to the side wall of the detection box 1 by bolts, etc., and the connecting plate 71 has a frame around it for supporting the placement of the radiator 72. Preferably, the connecting plate 71 and the radiator 72 are plug-in-matched and connected through the top two sides, and the bottom frame of the connecting plate 71 is used as a support member to support the radiator 72 from below.

[0042] like Figure 5 As shown, both sides of the top of the heat sink 72 have mounting portions extending outward, and a connecting groove 73 for placing the protruding mounting portion is correspondingly provided at the top of the connecting plate 71. The heat sink 72 is first overlapped at the position of the connecting groove 73 of the connecting plate 71 through the mounting portion. Secondly, a clamping hole 75 is further provided on the wall of the connecting groove 73. A clamping groove 74 is provided at a position corresponding to the clamping hole 75 on the protruding mounting portion of the heat sink 72. A second spring 77 and a clamping block 76 are sequentially provided in the clamping groove 74 along the direction close to the clamping hole 75. One end of the second spring 77 is fixed to the inner wall of the clamping groove 74, and the other end is fixed to the tail end of the clamping block 76. The front end of the clamping block 76 is used to cooperate and embed in the clamping hole 75. Similarly, when the card block 76 is embedded in the card hole 75 under the elastic force of the second spring 77, the active connection between the heat sink 72 and the connecting plate 71 is realized; when the card block 76 is pushed inward to compress the second spring 77 inward, the card block 76 can be disengaged from the card hole 75, making it easy to remove the heat sink 72.

[0043] In order to facilitate the pushing control of the card block 76, further, a pressure groove 78 parallel to the card groove 74 is further provided on the top of the connecting plate 71, and a pressure block 79 is connected to the pressure groove 78 through a third spring 710. One end of the third spring 710 is fixed to the inner wall of the pressure groove 78, and the other end is fixed to the tail end of the pressure block 79. The front end of the pressure block 79 continues to extend in the direction beyond the pressure groove 78. The pressure block 79 is slidably fitted in the pressure groove 78, and the end of the pressure block 79 extending beyond the pressure groove 78 is provided with a connecting rod extending in the direction of the card block 76. Figure 5 As shown, it can be set as an L-shaped connecting rod, the front end of which is directly opposite to the position of the block 76. When the pressing block 79 is pushed inward to squeeze the third spring 710, the front end of the L-shaped connecting rod gradually contacts the block 76 and simultaneously squeezes the second spring 77, so that the block 76 can be pushed to be separated from the clamping hole 75. This makes the operation more convenient.
