Description

Technical Field

[0001] The utility model relates to the technical field of photometers, in particular to an instantaneous digital photometer. Background Art

[0002] An instantaneous digital photometer is an instrument used to measure light intensity. It acquires and records light intensity changes in real time by converting light signals into digital signals. Compared with traditional photometers, instantaneous digital photometers have higher measurement accuracy and response speed, and can provide accurate data in a rapidly changing optical environment. In order to maintain the accuracy of the instantaneous digital photometer itself, it needs to be strictly stored when not in use to avoid errors caused by contaminants.

[0003] In the related art, a receiving groove is installed on the side wall of the photometer, and a rotating shaft is rotatably connected in the receiving groove. A dustproof cloth is connected through the rotating shaft. The dustproof cloth is taken out through the rotating shaft and wrapped around the top of the photometer to complete the protection of the photometer. However, due to the volume limitation of the photometer itself, the width of the receiving groove should be less than or equal to the width of the photometer, and the width of the dustproof cloth inserted into the receiving groove should be further smaller than the width of the receiving groove. Therefore, it is difficult to protect the photometer only by relying on a dustproof cloth whose width is smaller than that of the photometer. Utility Model Content

The storage component 2 is away from the bottom of the storage component 2 in the installation cavity 22. An open end 26 is provided at the end, and the dust cover 3 can be pulled out from the open end 26 for easy installation / recovery. A limiting rod 35 is provided at the end of the dust cover 3. In the present embodiment, the limiting rod 35 is an L-shaped structure, one end of which is inserted into the open end 26 to achieve a sealing effect, thereby preventing dust from entering the interior of the storage component 2 when not in use, and the other side of the L-shaped structure can facilitate the pulling out of the dust cover 3. Of course, a cylindrical or T-shaped structure can also have a similar effect. The entire dust cover 3 is folded in the installation cavity 22, and is pulled out and then unfolded by the limiting rod 35, so as to completely cover the photometer body 1, so that the entire structure is stable and can better protect the photometer body 1.

[0023] Combined with reference Figures 1 to 3 In one embodiment of the present application, the storage component 2 includes a shell 21 and a rotating shaft 23. The shell 21 is connected to the side wall of the storage component 2. A cover plate 25 is provided on the shell 21, and an open end 26 is opened on the cover plate 25.

[0024] In an instantaneous digital photometer of the present application, the storage assembly 2 includes a shell 21 and a rotating shaft 23. The shell 21 is connected to the photometer body 1. A cover 25 is provided on the upper part of the shell 21. An open end 26 is provided at the cover 25. The dust cover 3 can be maintained by opening the cover 25. The rotating shaft 23 is passed through the installation cavity 22, and a joystick 24 is provided through the shell 21. The dust cover 3 is rolled up in the installation cavity 22 through the rotating shaft 23. The dust cover 3 can be directly recovered through the joystick 24 when in use, and there is no need to stack the dust cover 3 additionally.

[0025] Combined with reference Figure 1 In one embodiment of the present application, the dust cover 3 includes a connecting section 31 and a main section 32, one end of the connecting section 31 is connected to the rotating shaft 23, and the other end is connected to the periphery of the cover plate 25; the main section 32 is connected to the connecting section 31, the main section 32 is covered on the photometer body 1, and one end of the main section 32 away from the connecting section 31 is connected to the limiting rod 35.

[0026] In an instantaneous digital photometer of the present application, the dust cover 3 is composed of a connecting section 31 and a main section 32. The connecting section 31 is located directly at the periphery of the rotating shaft 23 and the cover plate 25, and is used to push the main section 32 out of the range of the storage component 2, so that the main section 32 can more efficiently cover the photometer body 1 and play a role in dust protection. The limit rod 35 is connected to the main section 32. When the dust cover 3 is rolled up, the limit rod 35 can be clamped at the open end 26 to facilitate the next use of the dust cover 3. When in use, the dust cover 3 can be pulled out and used as a counterweight to facilitate the support of the dust cover 3 to achieve the purpose of stably protecting the instantaneous digital photometer body 1.

[0027] Combined with reference Figures 1 to 3 In one embodiment of the present application, a support area 33 is provided on the side of the dust cover 3, and a flexible support strip 331 is connected to the periphery of the support area 33. A folding area 34 is provided on the dust cover 3 away from the storage component 2, a limiting rod 35 is connected to the end of the folding area 34, and the flexible support strip 331 is connected to the limiting rod 35.

[0028] In an instantaneous digital photometer of the present application, a support area 33 is provided on the side of the dust cover 3, and a flexible support strip 331 is connected to the periphery of the support area 33.
