Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a portable methane gas detector comprises an instrument body 1, wherein a display screen 2 is fixedly mounted on the instrument body 1.

The above is noteworthy:

1. install sample probe rod 3 and a plurality of control switch 4 on the instrument body 1, display screen 2, sample probe rod 3 and a plurality of control switch 4 are common subassembly on the current portable methane gas detector, therefore its theory of operation and concrete structure do not describe here.

Referring to fig. 2, 3 and 5, a bottom plate 5 is mounted at the lower end of the device body 1, and a telescopic mechanism is mounted between the bottom plate 5 and the device body 1.

The above is noteworthy:

1. the telescopic mechanism consists of a side plate 7, a fixing plate 8, a moving groove 9, a through hole 10, a limiting rod 11, a pulling plate 12 and a plurality of limiting holes 13.

2. Curb plate 7 fixed mounting is on the lateral wall of

bottom plate

5, 8 fixed mounting of fixed plate is on curb plate 7, moving chute 9 is seted up on the lateral wall of instrument body 1, and moving chute 9 cooperatees with fixed plate 8, cooperation through fixed plate 8 and moving chute 9, can adjust the interval of 5 relative instrument bodies of bottom plate 1, when the operation personnel uses this detector, can move bottom plate 5 certain distance downwards, take operation that can accomplish this detector to bottom plate 5 afterwards, take place the hand and carry out the problem that the mistake was touched to control switch 4 on it when avoiding directly holding the detector, thereby can ensure the accuracy of testing result.

3. Fixed mounting has a plurality of slide bars 6 on the bottom plate 5, has seted up a plurality of slide holes on the diapire of instrument body 1, and every slide hole cooperatees with corresponding slide bar 6 respectively, and the length of every slide bar 6 all is greater than the length of fixed plate 8, through the cooperation of a plurality of slide bars 6 and a plurality of slide holes, can prescribe a limit to the moving direction of the relative instrument body 1 of bottom plate 5.

4. The through hole 10 is opened on the fixed plate 8, the limit rod 11 is inserted on the through hole 10, the pulling plate 12 is fixedly installed at one end of the limit rod 11 far away from the fixed plate 8, the limit holes 13 are opened on the side wall of the instrument body 1, each limit hole 13 is communicated with the movable groove 9, each limit hole 13 is matched with the limit rod 11, after the adjustment of the distance between the bottom plate 5 and the instrument body 1 is completed, the limit rod 11 is inserted into the through hole 10 from the corresponding limit hole 13, the bottom plate 5 can be limited relative to the instrument body 1, thereby the distance between the bottom plate 5 and the instrument body 1 can be kept stable, meanwhile, due to the design of the limit holes 13, the movable distance of the fixed plate 8 on the movable groove 9 is longer, therefore, the distance adjusting range of the bottom plate 5 relative to the instrument body 1 is larger, thereby when the methane detection is needed at a higher position and the arm length of an operator is not long enough to extend the sampling probe rod 3 into the detection position, the whole length of the detector is increased, so that the detection operation of the high detection position is facilitated.
