Abstract
The utility model discloses a ray shielding lead curtain for identifying a breakage situation easily and relates to the technical field of security check equipment. In order to solve the problem that the surface breakage situation of the lead curtain on the existing security check equipment is not easy to observe, the ray shielding lead curtain comprises a leaded inner layer and a packaging layer packaged outside the leaded inner layer and also comprises an indicating layer arranged between the leaded inner layer and the packaging layer for indicating the breakage situation of the packaging layer; and the indicating layer is arranged at one side of the leaded inner layer or is symmetrically arranged at the two sides of the leaded inner layer. The ray shielding lead curtain is used for equipment requiring the installation of a shielding lead curtain.
Description
Technical field
The utility model relates to the rays safety detection apparatus technical field, relates in particular to a kind of plumbous curtain of alpha ray shield that is easy to discern damaged situation.
Background technology
Screening machine is will be examined that luggage is sent into the X-ray examination passage and the electronic equipment of finishing inspection by means of conveying belt.It is widely used in the safety inspection of the high movable and tissue (unit) in airport, customs, land/extra large traffic department, security rank.
For guaranteeing that the safety check staff avoids x radiation x harm, the screening machine import/export all is equipped with the plumbous curtain of traditional rubber/mould.Plumbous curtain is to be made of the integument of leaded internal layer with the sealing internal layer.Leaded internal layer is the lead powder end to be dissolved in rubber or other rubber-plastics material make in the prior art, or evenly weaving the back forging and pressing by pure lead fiber silk makes, and the plumbous curtain with good suppleness and droop plays the effect that the shielding ray leaks in screening machine.Integument is then made by rubber or preferred thermoplastic polyurethane composite nylon cloth.Yet the article to be checked (luggage) that in a large number do not stop the to move integument that weares and teares continually adds the aging of plumbous curtain top layer chemical material, and the breakage on integument surface is still inevitable.At this moment, the lead in the leaded internal layer can be separated out and be escaped by damaged surface, as the plumbous curtain of untimely replacing, will safety check staff's health be worked the mischief, and environment is polluted.Made by black material and leaded internal layer and integument are many in the existing product, the damaged situation on plumbous curtain surface is difficult for observing.
Summary of the invention
The deficiency that is difficult for observation at existing plumbous curtain surface fracture situation.The purpose of this utility model provides a kind of plumbous curtain of alpha ray shield that is easy to discern damaged situation.
The technical scheme that its technical matters that solves the utility model adopts is: comprise leaded internal layer and be sealed and coated on the outer integument of described leaded internal layer that it also comprises and is arranged at the marker that is used to indicate described integument breakage situation between described leaded internal layer and the described integument.
Further, described marker is arranged at a side of described leaded internal layer or is symmetricly set in the both sides of described leaded internal layer.
Further, the thickness of described marker is 0.1mm～1mm.
Further, the color of described marker is different from described leaded internal layer and described integument.
Further, described marker is a reticular fibre cloth.
The beneficial effect of this patent is: the utility model is provided with marker between the leaded internal layer of plumbous curtain and integument, the color of marker and integument has tangible contrast.Because frequent friction and when damaged, the marker in it is exposed to point out the staff in time to change plumbous curtain, prevent separating out and escaping of plumbous material in the internal layer when the integument top layer, avoid the staff to be subjected to health hazard and public environment is polluted.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples;
Fig. 1 is the structural representation of embodiment one;
Fig. 2 is the structural representation of embodiment two;
The number in the figure explanation:
The leaded internal layer 2-of 1-integument 3-marker 4-grommet
Embodiment
Below will describe technology contents of the present utility model and feature in detail by cited embodiment in conjunction with the accompanying drawings.
Embodiment one: in conjunction with Fig. 1 a kind of plumbous curtain of alpha ray shield that is easy to discern damaged situation of the present utility model is described, it by leaded internal layer 1, be sealed and coated on leaded internal layer 1 outer integument 2 and two-layer marker 3 and constitute.Marker 3 is arranged between leaded internal layer 1 and the integument 2 and is positioned at the both sides of leaded internal layer 1.Hang for convenient, integument 2 is provided with the grommet 4 of circle hole shape structure.Marker 3 is the color with obvious contrast with the color of integument 2, and when integument 2 had local damage, the marker 3 in it exposed and is easy to be found by the staff, plays the effect of prompting, so that the staff in time changes plumbous curtain.Obviously the color of contrast can be contrast colors or has the color of luminosity equation.As black and white, black and Huang etc.Marker 3 can be made by the good wood of pliability or reticular fibre cloth or filament braid, rubber, plastics or other chemical materials.The thickness of marker 3 is 0.1mm～1mm.
Embodiment two: in conjunction with Fig. 2 present embodiment is described, different with embodiment one is, marker 3 is one deck, is arranged at leaded internal layer 1 and near between the integument 2 of article delivery direction A to be checked.
Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
Claims (5)
1. plumbous curtain of alpha ray shield that is easy to discern damaged situation, comprise leaded internal layer and be sealed and coated on the outer integument of described leaded internal layer, it is characterized in that: it also comprises and is arranged at the marker that is used to indicate described integument breakage situation between described leaded internal layer and the described integument.
