[0017] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0018] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.
[0019] Example 1
[0020] like Figure 1-3 As shown, a food safety detector includes a detector, a shell 1, a plurality of telescopic rods 6 are provided on the inner side of the top of the shell 1, a display screen 5 is provided on the top of the plurality of telescopic rods 6, a mounting plate 4 installed on the outside of the shell 1 and penetrating the shell 1 is connected to the side of the display screen 5, a cover is provided on the top of the mounting plate 4 and located on the outside of the shell 1, and a cover plate 3 is provided on the top of the shell 1, and a switch 2 is provided on the side of the bottom end of the shell 1.
[0021] The bottom end of the mounting plate 4 is cylindrical, and a plurality of teeth are provided on the outer side of the cylinder of the mounting plate 4, and the plurality of teeth are arranged at equal angles within three quarters of the circumference of the cylinder. A connecting plate is vertically extended downward on one side of the display screen 5, and a plurality of tooth grooves are provided on the side of the connecting plate to match the mounting plate 4. A through hole is provided on the top side of the shell 1, and the bottom end of the mounting plate 4 is rotatably mounted at the through hole of the shell 1, and one side of the bottom end of the mounting plate 4 is meshed and connected with the display screen 5 through the through hole, so as to drive the mounting plate 4 to rotate on the shell 1 while the display screen 5 moves up and down, so that the cover plate 3 is connected and separated from the shell 1.
[0022] The top of the shell 1 vertically expands upward to form a protrusion with a hollow center. The display screen 5 is located inside the protrusion. The inner side of the protrusion is adapted to the shape of the display screen 5 to accommodate the display screen 5 to avoid damage caused by external force.
[0023] A protrusion is provided at the bottom end of the cover plate 3, and the protrusion of the cover plate 3 is inserted into the inner side of the protrusion of the shell 1. An inclined notch is provided at the bottom end of one side of the protrusion of the cover plate 3, and the notch can avoid obstruction when the mounting plate 4 drives the cover plate 3 away from the protrusion of the shell 1.
[0024] Working principle:
[0025] When in use, the telescopic rod 6 is started by the switch 2, so that the telescopic rod 6 drives the display screen 5 to move upward on the inner side of the protrusion of the shell 1. At the same time, when the display screen 5 moves upward, the tooth groove of the display screen 5 drives the mounting plate 4 meshed with it to rotate at the through hole of the shell 1, so that the mounting plate 4 drives the cover plate 3 to separate from the protrusion of the shell 1, so that the display screen 5 appears at the top of the shell 1 and is flush with the top of the protrusion of the shell 1, and the panel of the display screen 5 can be operated. By reversing the above steps, the display screen 5 can be stored in the inner side of the shell 1 and protected by the cover plate 3.
[0026] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
