Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a sampling instrument with air adsorption heavy metal filters detection, including box 1, the mounting groove has been seted up to the bottom in box 1, horizontal rotation installs screw lead screw 2 in the mounting groove, both ends screw opposite direction and middle one section unthreaded about screw lead screw 2, box 1 lower surface rotates through the fixed block and installs dwang 3, the equal fixedly connected with gyro wheel 4 in dwang 3 both ends, dwang 3 surface is equipped with and is used for driving the together pivoted drive assembly of screw lead screw 2, box 1 lower surface rotates and installs two universal wheels 12, drive assembly is including fixed first gear 13 that cup joints in screw lead screw 2 one end, rotate and install second gear 14 and the fixed facial gear 15 that cup joints on dwang 3 surface at box 1 lower surface, first gear 13 wears out box 1 and meshes with second gear 14, second gear 14 meshes with facial gear 15.

When moving box 1, gyro wheel 4 takes place to rotate, the adjustable moving direction of universal wheel 12, because gyro wheel 4 is fixed cup joints on dwang 3 surface, dwang 3 rotates along with gyro wheel 4 rotates, the fixed face gear 15 that cup joints on dwang 3 surface rotates along with it this moment, and second gear 14 rather than the meshing also rotates along with it to rotate with first gear 13 of second gear 14 intermeshing, because first gear 13 cup joints with screw lead screw 2 is fixed, so screw lead screw 2 rotates along with first gear 13 inside box 1.

Symmetrical fixed mounting has the hinge bar in box 1, the equal symmetrical cover in two hinge bar surfaces is equipped with bracing piece 5, many bracing pieces 5 are kept away from the equal fixed mounting of hinge bar one end and are had clamp splice 6, the hinge bar below is equipped with

fixed plate

7, 7 fixed surface installations of fixed plate have many ejector pins 8, a plurality of fixed slots have been seted up to fixed plate 7 upper surface, many ejector pins 8 all pass through spring beam fixed mounting in the fixed slot, many ejector pins 8 all with bracing piece 5 sliding contact, 7 lower surfaces of fixed plate are equipped with the supporting component who is connected with screw lead screw 2, the supporting component includes that symmetrical screw thread cup joints the first slider 9 at screw lead screw 2, first slider 9 and mounting groove tank bottom sliding contact, two first slider 9 surfaces all articulate there is connecting rod 10, the spout has been seted up to fixed plate 7 lower surface, symmetrical sliding mounting has second slider 11 in the spout, two connecting rod 10 center department articulate each other and keep away from the one end of first slider 9 articulated with second slider 11 respectively.

When the box body 1 is moved, the threaded screw rod 2 horizontally and rotationally arranged in the box body 1 rotates through the transmission assembly, so that the first sliding blocks 9 symmetrically and slidably sleeved with the threaded screw rod 2 move oppositely, because the two first sliding blocks 9 are in sliding contact with the bottoms of the mounting grooves, the two first sliding blocks 9 can only move in the horizontal direction, when the two first sliding blocks 9 are close to each other, the two connecting rods 10 hinged to each other are close to each other, thereby driving the two second sliding blocks 11 which are slidably arranged in the sliding grooves on the lower surface of the fixed plate 7 to approach each other, under the action of which the fixed plate 7 moves upwards, the mandril 8 fixedly arranged on the upper surface of the fixed plate 7 presses the supporting rod 5 when the fixed plate 7 moves upwards, then the two clamping blocks 6 approach each other, so that the clamping block 6 clamps the sampling tank under the action of the ejector rod 8, the spring rod is compressed after clamping, the first sliding blocks 9 stop approaching each other until the two first sliding blocks 9 slide to the middle non-thread part of the thread screw rod 2, and the box body 1 clamps the sampling tank all the time in the moving process under the action of the spring rod, thereby preventing the damage of the sampling tank, when the sampling tank is moved to a proper position, only the roller 4 needs to be rotated in the reverse direction, under the action of the transmission component, the threaded screw rod 2 rotates in the opposite direction, under the action of the spring rod, the fixing plate 7 has the force of moving downwards, under the action of the connecting rod 10, the two first sliding blocks 9 have reverse movement force, under the combination of the force and the reverse rotation of the threaded screw rod 2, the two first sliding blocks 9 move on the threaded screw rod 2 in opposite directions, at the moment, under the action of the supporting component, the fixed plate 7 moves downwards, the support rod 5 then loses the compression of the ejector rod 8, so that the clamping block 6 no longer clamps the sampling tank, and finally the sampling tank can be taken out of the box body 1.

The contact surface of the clamping block 6 and the gas collecting bottle is an arc-shaped surface, the rubber pad is fixedly arranged on the surface of the clamping block 6, the rubber pad is made of rubber, the contact surface of the clamping block 6 is an arc-shaped surface, the clamping is more stable when the sampling tank can be clamped, and the rubber pad can increase the friction force between the clamping and the sampling tank.

The utility model discloses in, through removing box 1, gyro wheel 4 takes place to rotate, and rethread drive assembly, screw lead screw 2 rotate thereupon, and rethread supporting component makes fixed plate 7 upwards remove, recycles two clamp splice 6 of the effect of ejector pin 8 and is close to each other to the realization is tight to the sampling tank clamp.

Overall, the technical problem is addressed: most of sampling instruments directly place a sampling tank in a gas collection box without fixing by a fixing component, but the sampling tank is easily damaged in the outdoor moving process; the technical scheme is as follows: the sampling tank can be clamped while the box body 1 is moved through the action of the transmission assembly, the idler wheel 4, the threaded screw rod 2, the supporting assembly, the fixing plate 7, the ejector rod 8, the supporting rod 5 and the clamping block 6; the implementation process of the technical scheme is as follows: the roller 4 rotates by moving the box body 1, the threaded screw rod 2 rotates along with the roller by the transmission assembly, the fixing plate 7 moves upwards by the supporting assembly, and the two clamping blocks 6 are close to each other under the action of the ejector rod 8, so that the sampling tank is clamped; therefore, the technical problem can be solved certainly, and the technical effects are as follows: the sampling tank is clamped when the box body 1 is moved, sampling efficiency is improved, and loss is reduced.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
