Description

Technical Field

[0001] The utility model relates to the technical field of smoke meter equipment, in particular to a portable transmission smoke meter. Background Art

[0002] The smoke meter is an instrument for measuring the smoke density in automobile exhaust gas. It is mainly used for measuring exhaust gas from diesel engines. A piston pump is used to extract a certain volume of exhaust gas from the exhaust pipe of the diesel engine at a specified time, and it is passed through a filter paper of a certain area. The smoke particles in the exhaust gas are trapped on the filter paper and dye the filter paper black. The absorbance of the filter paper is measured by a photoelectric measuring device, and the absorbance indicates the size of the smoke density in the exhaust gas. The smoke meter is mainly composed of a piston pump, a sampling device and a photoelectric measuring device.

[0003] Traditional smoke meters are large in size and inconvenient to carry, so a handle is provided on the shell of the smoke meter for carrying it by hand. However, it is still inconvenient to carry it with one hand for a long time. Therefore, it is necessary to design a structure that can replace the one-handed carrying of the transmission smoke meter, reduce the fatigue of carrying, and meet the demand of long-term carrying.

[0013] 1. The utility model provides a portable bag to store and hide the portable bag. The upper and lower binding belts of the portable bag are wound around the outer wall of the shell, which improves the structural stability of the portable bag and prevents the portable bag from being unable to bear the weight of the shell and its internal components for a long time. The shoulder strap replaces the handle to meet the long-term carrying demand, freeing both hands and meeting the long-term carrying demand. The portable bag can be stored in the portable bag when not in use, and has good portability.

[0014] 2. The utility model provides an upper back pad and a lower back pad, so that the user does not need to directly contact the bottom of the shell, thereby improving the comfort of the user's back. At the same time, the upper back pad and the lower back pad can be rolled up and stored when not in use, which is convenient to use.

[0015] 3. The utility model can switch between the carrying strap and the handle of the portable bag to meet the use requirements of different use environments. BRIEF DESCRIPTION OF THE DRAWINGS
