Description of the embodiments

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in fig. 1-4, the atomic absorption spectrometer protective cover comprises a top cover 1 and a surrounding block 2, wherein one side wall of the top cover 1 is hinged with the surrounding block 2, the opposite side wall of the hinged side wall of the top cover 1 and the surrounding block 2 is in clamping connection with the surrounding block 2, the contour of the surrounding block 2 corresponds to the contour of an atomic absorption spectrometer 8 and is in clamping connection with the atomic absorption spectrometer 8, the top cover 1 corresponds to the contour of the surrounding block 2 and is covered with the surrounding block 2, and a through hole 3 for a smoke suction pipe 9 of the atomic absorption spectrometer 8 to pass through is formed in the side wall of the surrounding block 2; enclose and keep off 2 on set up first buckle group 4, second buckle group 5, third buckle group 6, first buckle group 4 is articulated with enclose fender 2 bottom surface, and first buckle group 4 card is at the instrument both sides that atomic absorption spectrometer 8 set up sampling needle 10, second buckle group 5, third buckle group 6 and enclose fender 2 lateral wall fixed connection, second buckle group 5 and third buckle group 6 position correspond and all block on the instrument that atomic absorption spectrometer 8 has combustor 11. The buckles of the first buckle group 4, the second buckle group 5 and the third buckle group 6 are provided with anti-skid structures; the anti-skid structure is a rubber cushion layer 7.
