Description
Technical Field
The utility model relates to a face guard lens luminousness survey device belongs to special equipment and detects inspection technical field.
Background
The air respirator comprises components such as an air cylinder, a back support, a face mask and the like, is widely applied to departments such as fire control, chemical engineering, ships, petroleum, smelting, warehouses, laboratories, mines and the like, and is used for fire extinguishment, rescue and relief work and rescue work of firemen or rescue and rescue personnel under various environments such as dense smoke, toxic gas, steam or oxygen deficiency. The mask of the air respirator is provided with a lens, and the light transmittance of the mask lens is not lower than 85% according to the national standard requirement. When adopting traditional mode to survey, need one person handheld face guard, another person holds two measuring probe of luminometer respectively and keeps the certain distance, and the axle center aligns and places respectively in the lens both sides, troublesome poeration, detection efficiency hangs down. And if not properly operated, may result in inaccurate measurement of the light transmittance.
SUMMERY OF THE UTILITY MODEL
According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the mask lens light transmittance measuring device overcomes the defects of the prior art, is simple and standard to operate, and enables the measuring result to be more accurate.
Face guard lens luminousness survey device, including the test head mould that can control the removal, including the metal box, be equipped with U type piece on the metal box, U type piece both ends are equipped with measuring probe respectively, two measuring probe with axle center mutual disposition, measuring probe passes through the wire and connects the luminometer, the setting of luminometer is in the metal box.
The U-shaped block keeps a certain distance between the two measuring probes and fixes the two measuring probes with the same axle center, so that the precondition is kept consistent during each measurement, and the precondition accords with the specification. When carrying out the luminousness survey of face guard lens, only need an operating personnel to put the face guard between the U type piece, make the lens be in between two measuring probe, open the luminousness appearance survey can, easy and simple to handle the standard, the testing result is more accurate.
Preferably, through holes are formed in two sides of the U-shaped block, the diameter of each through hole is matched with the outer diameter of the measuring probe, and the measuring probe is arranged in the through holes and fixed through locking screws.
Preferably, the metal box body is provided with a box door, so that the light transmittance instrument can be conveniently overhauled and the battery can be conveniently replaced.
Compared with the prior art, the utility model beneficial effect who has is:
face guard lens luminousness survey device, structural design is reasonable, provides the complete equipment of one set of standard for face guard lens luminousness survey, U type piece keeps certain distance and fixed with the axle center with two measuring probe, the precondition when making at every turn measure keeps unanimous for easy and simple to handle the standard, the testing result is more accurate, has reduced operating personnel quantity, and has improved the measurement of efficiency.

In the figure: 1. a U-shaped block; 2. a measuring probe; 3. locking the screw; 4. a metal box body; 5. a control button; 6. a display screen; 7. a box door; 8. a light transmittance instrument.
Detailed Description
The invention will be further described with reference to the following examples:
as shown in fig. 1 ~ 3, face guard lens luminousness survey device, including metal box 4, be equipped with U type piece 1 on the metal box 4, 1 both ends of U type piece are equipped with measuring probe 2 respectively, two measuring probe 2 with axle center mutual disposition, measuring probe 2 passes through the wire and connects luminousness appearance 8, luminousness appearance 8 sets up in metal box 4.
The metal case 4 of the present embodiment has an L shape.
The both sides of U type piece 1 of this embodiment are equipped with the through-hole, and the diameter of through-hole and 2 external diameter looks adaptations of measuring probe, measuring probe 2 arranges in the through-hole to it is fixed through locking screw 3.
The metal box 4 of this embodiment is provided with a box door 7, and the box door 7 is provided with a door lock.
When the device is used, the luminometer 8 is opened through the control button 5, the lens of the testing mask is placed between the U-shaped blocks 1 after the zero setting, the indicating value of the device is read through the display screen 6, and the value on the display 6 is the measured value of the object to be tested. The utility model discloses a face guard lens luminousness survey provides the complete equipment device of one set of standard, and U type piece 1 keeps certain distance and fixed with the axle center with two measuring probe, and the precondition when making at every turn measure keeps unanimous for easy and simple to handle the standard, reduced operating personnel quantity, and improved survey efficiency.
