Description

Placement box of dosage rate meter

Technical Field

The utility model relates to an environmental protection technology field, concretely relates to dose rate appearance.

Background

Patent document with an authorization publication number of CN 207301346U discloses a portable X and gamma dose rate meter, which comprises a device body, wherein the device body comprises the X and gamma dose rate meters and a placing box for placing the X and gamma dose rate meters. When needs use X, during gamma dose rate appearance, the extrusion push rod drives two sliders simultaneously and is close to the centre, and first spring compression holds power, and the bracing piece slides in the spout through the pulley and rises, and the board rises to the drive of placing, when placing the board and rise, the spacer pin atress extrusion second spring, second spring compression recovery breaks away from the spacing groove with the spacer pin this moment to slide on the slide rail, be favorable to placing the board and rise at the slide rail and get and take. The problem that its exists is, manual operation is difficult to make two sliders be close to the centre in step, so, and one of them slider makes the spacer pin of homonymy break away from the spacing groove, and another slider has not made the spacer pin of homonymy break away from the spacing groove yet, leads to placing the board jamming or card and dies, places the smooth and easy nature of board action and can not obtain the assurance.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the placing plate of the dose rate meter placing box can smoothly move along the sliding rail.

In order to solve the technical problem, the utility model provides a following technical scheme: the placing box of the dose rate meter comprises a box body, a placing plate and an unlocking and lifting mechanism; the pair of inner side walls of the box body are provided with slide rails, the left end and the right end of the placing plate are matched in the slide rails, the slide rails are provided with limiting grooves, the left end and the right end of the placing plate are provided with elastic components, and the elastic components can be clamped in the limiting grooves; supporting rods are arranged below the left end and the right end of the placing plate; the unlocking and lifting mechanism comprises a left sliding block and a right sliding block, the left sliding block and the right sliding block are matched in the guide rail, the left sliding block and the right sliding block are both provided with arc surfaces, and the bottom ends of the two supporting rods are pressed against the arc surfaces of the two sliding blocks in a one-to-one mode; the left sliding block is hinged with a left connecting rod, the right sliding block is hinged with a right connecting rod, the left connecting rod is hinged with the right connecting rod through a hinge pin, and the hinged part of the left connecting rod and the right connecting rod is hinged with an unlocking rod through the hinge pin; the left connecting rod is hinged with the left sliding block through a left pin, the right connecting rod is hinged with the right sliding block through a right pin, and the distance between the left pin and the hinge pin is equal to the distance between the right pin and the hinge pin.

According to above-mentioned technical scheme, the box body is put into from top to bottom to the dose rate appearance, and the board is placed along slide rail downstream in the promotion, and when elastic component met the spacing groove, the elastic component card was gone into in the spacing groove, placed the board and stopped the action, and the dose rate appearance is placed and is targetting in place. When the dose rate meter needs to be taken out of the box body, the unlocking rod protruding out of the box body is pressed, and the unlocking rod drives the left connecting rod and the right connecting rod to rotate. Because the distance of left round pin and hinge pin equals the distance of right round pin and hinge pin, consequently, left connecting rod drive left slider, right connecting rod drive right slider are synchronous, and the displacement of left slider equals the displacement of right slider, so, can guarantee to place the board about the elastic component at both ends break away from respectively the complex spacing groove in step, can guarantee to place the board about both ends synchronous and equidistance rise, and then, place the board and can smoothly follow the slide rail motion. The level of the placing plate rises, so that the dose rate meter is smoothly pushed out of the box body.

Place the box, except depositing and conveniently carrying the dose rate appearance, still have the guard action to the dose rate appearance.
