The end that two clamping plates 431 extend stretches out formed with can be fitted with planes carry things such as metopes respectively Fixed part 433, at least one fixing hole 4331 is offered on fixed part 433, fixed part 4331 and the planes such as metope can be held Loading is fixed together using bolt.

The inner side of every piece of clamping plate 431 equidistantly uniformly offers clip tooth 4311 along the bearing of trend of clamping plate 431, and clip tooth 4311 is in Stepped distribution extends to fixed part 433, when clamping plate 431 is clamped on the cylindricality carriers such as electric pole, big tree, clip tooth 4311 can play a part of anti-skidding, anti-rotation, improve the stability of mounting seat installation.

The connection inner transverse of main body 41 offers at least one and penetrates passage 45 for what tape fastener 44 penetrated, preferably Penetrate passage 45 and offer two, in installing is put side by side up and down.

The corresponding opening 4312 for offering connection and penetrating passage 45, the energy of tape fastener 44 in the plate face of clamping plate 431 Enough openings 4312 from the inner side of clamping plate 431 of one end penetrate and by penetrating the opening from other end of clamping plate 431 of passage 45 Mouth 4312 passes to form ring encapsulation circle.

In order to cause tape fastener 44 to be bonded even closer with penetrating passage 45, the inside of passage 45 is penetrated away from card The curved setting of the wall of socket part 43 and both ends are extended at opening 4312.

Tape fastener 44 can select hose clamp and other can form lasso and hold tightly and be held in cylindricalitys such as electric pole, big trees Connector in loading.

When needing to be arranged into air quality sensor monitoring instrument on the cylindricality carriers such as electric pole, big tree, it is only necessary to will Two hose clamp is penetrated in mounting seat 40, and mounting seat 40 is clamped on the cylindricality carriers such as electric pole, big tree by clamping plate 431, Then mounting seat 40 is locked by two anchor ears；When needing air quality sensor monitoring instrument being arranged into the planes carries such as metope When on thing, it is only necessary to by the planes carry things such as the horizontal abutment of fixed part 433 of mounting seat 40 to metope, then worn by bolt Mounting seat 40 is locked by the fixing hole 4331 crossed on fixed part 433.

The structure of mounting seat 40 in the present embodiment is relatively simple, easy to operate, quick, can either be arranged into big tree, electric wire On the cylindricality carrier such as bar, it can also be arranged on the planes carry thing such as plane wall, use range is wider, being capable of extensive cloth Net.

This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
