Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1 to 3, a portable police footprint collecting device structurally comprises a box body 1 and a pressure sensing collecting device 2, wherein the front end and the bottom of the box body 1 are open, the pressure sensing collecting device 2 is slidably mounted inside the box body 1 and slides out of the box body 1, a darkroom bin 1a is formed inside the box body 1, lamp strips 3 are uniformly distributed on the lower edge of the rear side inside the darkroom bin 1a and the lower edge of the back side of the pressure sensing collecting device 2, a footprint scanner 4 is arranged at the top of the darkroom bin 1a, and wheels 6 are mounted at the two ends of the box body 1 and can be lifted up and down through a lifting mechanism 5.

The method comprises the steps that after a criminal investigation person finds a footprint at a crime scene, the footprint acquisition equipment is moved to the footprint, then the pressure sensing acquisition device 2 is pulled out manually, when the pressure sensing acquisition device 2 slides out of the box body 1, wheels 6 are automatically retracted to the position above the lower surface of the box body 1 through a lifting mechanism 5, a darkroom bin 1a is tightly attached to the ground of the footprint, and after a lamp strip 3 in the darkroom bin 1a is opened, a footprint scanner 4 can scan and acquire the footprint.

As shown in fig. 4, after the pressure sensing collection device 2 is drawn out by sliding, the relevant personnel on site can step on the device to collect their shoe imprints, thereby facilitating the discharge of the footprints of the personnel on site during the subsequent evidence analysis.

As shown in fig. 5 and 6, the two ends of the top side of the box body 1 are symmetrically provided with the inserting structures 1c, so that other criminal investigation equipment a can be conveniently combined and buckled on the box body 1, and the whole box body is convenient to carry. And based on the elevating action of wheel 6, even if carry multiple criminal investigation equipment A wholly, when the footprint was gathered, the footprint collection equipment that is located the bottommost was not dismantled, also can carry out footprint collection work. Meanwhile, in order to facilitate the integral moving, the wheels 6 are preferably universal wheels.

As shown in fig. 5 and 6, since the battery 7 is installed in the box body 1, the plug-in structure 1c is made into a jack shape, which not only can play a role of connection, but also can enable each layer of criminal investigation equipment a to share a power supply after being buckled together. When the police footprint acquisition equipment is used independently, the plug-in structure 1c in the shape of the jack can also provide power for other on-site electric equipment.

As shown in fig. 2 and 3, in this embodiment, the specific structure of the lifting mechanism 5 driving the wheels 6 to lift is as follows:

the wheel 6 is installed on wheel carrier 6a, the wheel carrier 6a can reciprocate install at 1 both ends of box, elevating system 5 includes dead lever 5a, movable rod 5b, supporting column 5c and spliced pole 2a four parts, wherein supporting column 5c sets firmly on box 1, spliced pole 2a sets firmly on the lateral wall of forced induction collection system 2, the upper end of movable rod 5b is rotated and is installed on the outer end tip of spliced pole 2a, the lower extreme slides flexible connection at length direction with dead lever 5a, the lower extreme of dead lever 5a rotates with wheel carrier 6a to be connected, the middle part of dead lever 5a uses supporting column 5c to rotate as the rotation fulcrum and installs on the lateral wall of box 1. For the assembly of spliced pole 2a, still be equipped with bar hole 1b on the lateral wall of box 1, this bar hole 1b is passed to spliced pole 2 a's outer end, when forced induction collection system 2 outwards slides, slide in bar hole 1b through spliced pole 2a, the upper end of pulling movable rod 5b outwards removes, because movable rod 5b, dead lever 5a both are telescopic connection, so dead lever 5a will be rotatory round supporting column 5c this moment, thereby drive following wheel carrier 6a rebound, in order to realize that the automation of wheel 6 is withdrawed. Since the fixing rod 5a rotates around the supporting post 5c, the wheel frame 6a moves upward and has a certain amount of movement in the front-rear direction, so that the box 1 can be made into a hollow structure at the position for accommodating the lifting mechanism 5 to prevent the movement interference.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
