Description

Technical Field

[0001] The utility model relates to the technical field of photometers, in particular to a compact ultraviolet spectrophotometer. Background Art

[0002] Ultraviolet-visible spectrophotometer (abbreviated as UV spectrophotometer or spectrophotometer) is an instrument that uses the absorption of light within a certain wavelength range by the molecules or ions of a substance to perform qualitative, quantitative and structural analysis on a substance.

[0003] After consulting the literature, it is learned that most of the existing ultraviolet spectrophotometers are basically used for the convenience of judging the absorbance at certain characteristic wavelengths on the absorption spectrum or determining the content of the substance. However, in order to ensure that the ultraviolet spectrophotometer is not directly in contact with the ground or the desktop and is not damaged by water contamination, most ultraviolet spectrophotometers are usually provided with support feet under the ultraviolet spectrophotometer. However, the support feet of most ultraviolet spectrophotometers are relatively high, which results in a waste of resources when the ultraviolet spectrophotometer is designed to be stored in a corresponding box, and there is a disadvantage of a large space occupancy rate when the ultraviolet spectrophotometer is placed. Summary of the invention

[0006] As a preferred technical solution, a pressure plate for squeezing the airbag is also provided inside the groove, and a screw hole connected to the outside world is provided on the top surface of the groove. The screw hole is arranged to avoid the electronic components inside the photometer body.

[0008] As a preferred technical solution, the outer end faces of the base all form a triangular structure.

[0009] As a preferred technical solution, both the airbag and the cylindrical bag are made of elastic rubber material.

[0010] As a preferred technical solution, the cover plate is threadedly connected to the groove.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a compact ultraviolet spectrophotometer of the utility model comprises a photometer body 1, four corners of the bottom of the photometer body 1 are provided with assembly grooves 2, a base 8 is arranged in the assembly groove 2, both sides of the assembly groove 2 are provided with inclined slide grooves 3, both sides of the base 8 are installed with sliders 11 of inclined structure, the sliders 11 are slidably arranged in the slide grooves 3, a groove is provided on the bottom surface of the photometer body 1, a cover plate 9 is installed in the opening of the groove, an airbag 13 is provided inside the groove, a through hole connected with the assembly groove 2 is provided on the inner ring surface of the groove, a cylindrical capsule 14 connected with the airbag 13 is installed at the outer ring surface of the airbag 13 opposite to the through hole, the cylindrical capsule 14 is inserted into the through hole, and a push rod 10 for pushing the base 8 outward is installed.

[0022] In this embodiment, a pressure plate 12 for squeezing the airbag 13 is further provided inside the groove, and a screw hole communicating with the outside is provided on the top surface of the groove. The setting of the screw hole avoids the electronic components inside the photometer body 1, and a screw rod 5 is threadedly connected in the screw hole. One end of the screw rod 5 extends to the outside through the screw hole, and a hand wheel 6 is installed. A bearing is embedded on the top surface of the pressure plate 12, and the other end of the screw rod 5 is installed in the inner ring of the bearing.

[0023] In this embodiment, a stopper 4 is installed in the opening outside the slide groove 3, and a compression spring 7 is provided inside the slide groove 3. One end of the compression spring 7 is installed on the stopper 4, and the other end is installed on the slider 11.

[0024] In this embodiment, the outer end faces of the base 8 are formed into a triangular structure, so that after the base is extended upward, the triangular portion on the base is inserted into the corner inside the box, which increases adaptability.

[0025] In this embodiment, the airbag 13 and the cylindrical bag 14 are both made of elastic rubber material, so that after the cylindrical bag is squeezed, it can expand outward and push the push rod outward along the through hole.

[0026] In this embodiment, the cover plate 9 is threadedly connected to the groove, which facilitates opening of the cover plate.

[0027] When it is necessary to store in a small space, the screw rod can be rotated by the hand wheel to move the screw rod upward along the screw hole. The movement of the screw rod drives the pressing plate. After the pressing plate is removed from the air bag, the gas in the cylindrical bag can flow back into the air bag, causing the push rod to lose its outward thrust. At this time, the base can be pushed inward by the rebound of the compression spring, so that the base moves along the slide groove to the deepest part of the assembly groove, so that the base does not protrude from the bottom surface of the photometer body, thereby avoiding waste of resources.

[0028] When the photometer needs to be lifted upward through the base, the screw rod can be rotated in the opposite direction to move the screw rod downward along the screw hole. The movement of the screw rod drives the pressing plate, and the pressing plate can squeeze the air bag, so that the gas in the air bag is pressed into the cylindrical bag, so that the cylindrical bag extends outward and pushes the push rod outward. The push rod extending outward can push the base outward, so that the base moves outward along the inclined slide groove. During the movement, the base can slowly protrude from the body of the photometer, so that the photometer can be propped up through the base, avoiding contact with moisture on the desktop;

[0029] Among them, after the photometer body is placed in the box, the hand wheel can be rotated again to move the base outward and against the corner of the inner cavity of the box, so that the photometer body is stuck inside the box, which increases the stability after prevention.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
