Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-3, a poisonous and harmful gas monitoring devices, including body 1, the one side fixedly connected with winding area 2 of screen is kept away from to body 1, a plurality of bayonet socket 3 is seted up on the surface of winding area 2, the one side fixedly connected with that body 1 kept away from the screen is the fixture block 4 of L shape, fixture block 4 wears to locate the inside of one of them bayonet socket 3, the one side fixedly connected with that body 1 kept away from the screen is the gag lever post 5 of U-shaped, gag lever post 5 is located between winding area 2 and the fixed one end of body 1 and fixture block 4, the inside of gag lever post 5 is worn to locate by winding area 2.

The scheme has the following working processes:

when need using body 1 to carry out gas monitoring, need the manual work to carry portable monitoring instrument and detect inside the mill, insert the palm earlier between winding area 2 and body 1, then take 2 stimulations with the winding to make suitable bayonet socket 3 worn by fixture block 4, take 2 to extrude the palm through the winding, the restriction through gag lever post 5 prevents that winding area 2 does not contact with the palm simultaneously, later use the thumb to operate body 1, detect the air through the screen, in the use, can not lead to body 1 to drop because of the hand is smooth and damage.

According to the working process, the following steps are known:

can be when the inspection, can restrict the palm through bayonet socket 3 on the winding area 2 and fixture block 4 on the body 1, prevent that the body 1 that the hand cunning leads to breaks away from the palm and falls for body 1 can not damage in the inspection, can normally use.

Further, the one side fixedly connected with that body 1 kept away from the screen is circular shape restriction cover 6, and winding area 2 is kept away from to restriction cover 6, and is concrete, and inside the middle finger of palm inserted restriction cover 6, can assist the winding area 2 to the restriction of palm for body 1 can not drop the damage.

Further, the top of body 1 is rotated and is connected with two semicircular protective sheaths 7, is equipped with fixed establishment 8 between two adjacent protective sheaths 7, and is concrete, and protective sheath 7 can protect the detecting head at body 1 top, surveys time measuring when needs, need extract body 1 with the detecting head and go on, then protects the detecting head through fixed establishment 8 is fixed with two protective sheaths 7 for the detecting head can prevent damage at the exploration in-process.

Further, the fixing mechanism 8 includes a U-shaped fixing block 801 fixedly connected to one side of one of the protection sleeves 7, a fixing rod 802 is fixedly connected to a side surface of the other protection sleeve 7, the fixing rod 802 is inserted into the fixing block 801, an accommodating groove 803 is formed on a surface of the fixing rod 802, the inside of the accommodating groove 803 is elastically connected with an anti-falling block 805 through an extrusion spring 804, specifically, when two protection sleeves 7 need to be fixed, the fixing rod 802 of one of the protection sleeves 7 penetrates through the fixing block 801, the anti-falling block 805 needs to be extruded into the accommodating groove 803 in the process of penetrating through the fixing block 801, after the fixing rod 802 is passed through, the anti-slip block 805 is released, so that the anti-slip block 805 is separated from the inner groove of the barrel by the elastic force of the pressing spring 804, so that the fixing rod 802 cannot be separated from the fixing block 801, when the two protection sleeves 7 need to be separated, the anti-falling block 805 can be pressed, and then the two protection sleeves 7 are rotated to separate the fixing block 801 and the fixing rod 802.

Further, the top fixedly connected with of protective sheath 7 is half cone's guide block 9, and air channel 10 has been seted up on the surface of guide block 9, and is concrete, and guide block 9 can guide the air to enter into the detecting head, and air channel 10 can prevent that the unable edgewise of air from getting into the detecting head.

Further, two standing grooves 11 have been seted up at the top of body 1, two standing grooves 11 are close to two protective sheaths 7 respectively, there is the block 13 that is the L shape one end of standing groove 11 through torsional spring pivot 12 elastic connection, it is concrete, after surveying, receive the detecting head behind body 1 is inside, can rotate protective sheath 7 and make protective sheath 7 enter into adjacent standing groove 11 inside, rotate the in-process earlier and rotate block 13, get into standing groove 11 inside at protective sheath 7 completely after, release block 13, block 13 and restrict protective sheath 7 through torsional spring pivot 12's elasticity.

To sum up, when using body 1 to detect poisonous and harmful gas, can take down the inside monitoring instrument and detect, can prevent the damage that body 1 breaks away from the palm and leads to through using winding area 2 at the in-process that detects, can protect the detecting head of body 1 through protective sheath 7 simultaneously.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
