Description

Technical Field

[0001] This utility model specifically relates to a portable mercury analyzer. Background Technology

[0002] Existing portable mercury analyzers typically have buckles on both ends of a rope for easy carrying. However, the display screen is exposed and easily damaged. Furthermore, if the support surface is uneven, the overall shaking of the machine can easily affect the accuracy of the test. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a portable mercury analyzer in order to overcome the shortcomings of the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a portable mercury analyzer, including a main body, a display screen and four connection holes are provided on the upper surface of the main body, the four connection holes are respectively located at the four corners of the upper surface of the main body, the display screen is located in the middle of the upper surface of the main body, and the connection holes are cylindrical.

[0005] The display screen is provided with a cover plate on top, and four connectors are provided on the lower end surface of the cover plate. The four connectors are respectively located in four connection holes.

[0006] The connector includes a connecting post and a support block. The lower end of the connecting post has a threaded hole, and the upper end of the support block has a screw. The screw is threadedly connected to the threaded hole, and the support block is connected to the connecting post through the screw. The connecting post is cylindrical, and the support block is frustoconical. The diameter of the upper end face of the support block is larger than the diameter of the lower end face. The depth of the connecting hole is greater than the sum of the heights of the connecting post and the support block. Two connecting strips are provided below the main body. The vertical cross-section of the connecting strips is inverted T-shaped. The upper end face of the cover plate has two limiting grooves that match the connecting strips. The positions of the two limiting grooves correspond one-to-one with the two connecting strips.

[0007] The connecting post and the connecting hole are interference-fitted.

[0008] Preferably, in order to reduce rigid contact and improve the stability of the support, the support block is made of hard rubber.

[0009] Preferably, to improve the strength and stability of the support, the screw is arranged vertically, with its lower end extending into the support block and the screw being fixedly connected to the support block.

[0010] Preferably, in order to accommodate various hanging methods, buckles are provided on all four sides of the main body.

[0011] The beneficial effects of this utility model are that the portable mercury analyzer provides physical protection for the display screen by setting a cover plate above the display screen, reducing the probability of damage to the display screen surface. In use, the cover plate can also be used as a support, which not only provides firm support but also allows for local height adjustment, improving the stability of the support and thus improving the accuracy of the detection data.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] like Figure 1-4 As shown, a portable mercury analyzer includes a main body 1. The upper surface of the main body 1 is provided with a display screen 2 and four connection holes 8. The four connection holes 8 are respectively located at the four corners of the upper surface of the main body 1. The display screen 2 is located in the middle of the upper surface of the main body 1. The connection holes 8 are cylindrical.

[0020] The display screen 2 is provided with a cover plate 3 above it, and four connectors 7 are provided on the lower end surface of the cover plate 3. The four connectors 7 are respectively located in four connection holes 8.

[0021] The connector 7 includes a connecting post 7-1 and a support block 7-2. The lower end of the connecting post 7-1 is provided with a threaded hole, and the upper end of the support block 7-2 is provided with a screw 7-3. The screw 7-3 is threadedly connected to the threaded hole. The support block 7-2 is connected to the connecting post 7-1 through the screw 7-3. The connecting post 7-1 is cylindrical, and the support block 7-2 is frustoconical. The diameter of the upper end face of the support block 7-2 is larger than the diameter of the lower end face. The depth of the connecting hole 8 is greater than the sum of the heights of the connecting post 7-1 and the support block 7-2. Two connecting strips 4 are provided below the main body 1. The vertical cross-section of the connecting strips 4 is inverted T-shaped. Two limiting grooves 5 matching the connecting strips 4 are provided on the upper end face of the cover plate 2. The positions of the two limiting grooves 5 correspond one-to-one with the two connecting strips 4.

[0022] The connecting post 7-1 is interference-fitted with the connecting hole 8.

[0023] Preferably, in order to reduce rigid contact and improve the stability of the support, the support block 7-2 is made of hard rubber.

[0024] Preferably, in order to improve the firmness and stability of the support, the screw 7-3 is arranged vertically, the lower end of the screw 7-3 extends into the support block 7-2 and the screw 7-3 is fixedly connected to the support block 7-2.

[0025] Preferably, in order to accommodate various hanging methods, the main body 1 is provided with buckles 6 on all four sides.

[0026] Four buckles 6 are set on the main body 1. Users can decide which buckles 6 to tie the end of the hanging rope to according to their actual needs and the way the strap is hung, thus improving the user experience.

[0027] When not in use, the cover plate 3 is placed on top of the display screen 2, and the four connecting posts 7-1 are located in the four connecting holes 8 respectively. Since the connecting posts 7-1 and the connecting holes 8 are interference fit, the cover plate 3 can be stably placed on top of the display screen 2. In fact, there is a gap between the cover plate 3 and the display screen 2, and the cover plate 3 serves as physical protection for the display screen 2.

[0028] When in use, remove the cover plate 3, that is, pull out the connecting post 7-1 from the connecting hole 8, and then snap the limiting groove onto the connecting strip 4, so that the cover plate 3 is fixed under the main body 1. The four support blocks 7-2 become the four support feet of the main body 1, providing stable support. The support blocks 7-2 are connected to the connecting post 7-1 by screws 7-3. Here, the height of the support blocks 7-2 can be finely adjusted by turning them, thereby absorbing the unevenness of the support surface and achieving the effect of stable support at the four corners, thus ensuring the overall stability, reducing the impact of shaking, and improving the detection accuracy.

[0029] Here, the combination of cover plate 3 and connector 7 can not only provide physical protection for display screen 2, but also serve as a base support function. It can be switched freely and is convenient to use. When used as a support, it also serves to store cover plate 3.

[0030] Compared with existing technologies, this portable mercury analyzer provides physical protection for the display screen 2 by setting a cover plate 3 above the display screen 2, reducing the chance of damage to the surface of the display screen 2. In use, the cover plate 3 can also be used as a support, which not only provides firm support but also allows for local height adjustment, improving the stability of the support and thus improving the accuracy of the detection data.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
