Further, connector 220 also has T-flange 222, and T-flange 222 is circumferentially disposed along connector 220.Base Body 210 has T-slot 211, and T-slot 211 is arc-shaped, and the radius of the circle corresponding to T-slot 211 is slightly larger than the institute of T-flange 222 The radius of corresponding circle.The circle corresponding to circle and T-flange 222 corresponding to T-slot 211 is coaxially disposed with connector 220. T-flange 222 is placed in T-slot 211, and T-flange 222 slideably coordinates with T-slot 211.Circle corresponding to T-slot 211 The length of arc accounts for 2/9ths of whole circumference girth.

Designed more than, when connector 220 is rotated relative to matrix 210, T-flange 222 is slided along T-slot 211.This Sample can greatly improve stability of the connector 220 in rotation process.In addition, when connector 220 and flange arrangement are completed After engaging, stability of the connector 220 with respect to matrix 210 can be further improved by being placed in the T-flange 222 of T-slot 211, To improve the connective stability of whole methane detector 1000.

Further, please refer to Fig.1, Fig. 6, Fig. 7 and Fig. 8, methane detector 1000 further includes telescopic component 300.Matrix 210 are connected to detector body 100 by telescopic component 300, and one end of telescopic component 300 is connected to detector body 100, stretch The other end of component 300 is connected to matrix 210.Connection component 200 can be used in stretching telescopic component 300 so as to be located at detector The connection component 200 at the both ends of body 100 is located remotely from each other, and telescopic component 300 is additionally operable to drive two positioned at detector body 100 The connection component 200 at end is close to each other.

Designed more than, telescopic component 300 can not only make the connection component positioned at the both ends of detector body 100 200 are located remotely from each other, and enable the connection component 200 of methane detector 1000 longer suitable for the length of nut to bolt head Flange arrangement, further expands the scope of application of methane detector 1000.Simultaneous retractable component 300 is additionally operable to drive positioned at inspection It is close to each other to survey the connection component 200 at the both ends of instrument body 100, with ensure connection component 200 can firmly with flange arrangement Nuts and bolt head engaging, improve installation after stability.

Further, telescopic component 300 includes elastic force cylinder 310, motion bar 320 and elastic component 330.Motion bar 320 is along bullet The axial of power cylinder 310 sets and runs through elastic force cylinder 310, and motion bar 320 can be slided along its axially opposing elastic force cylinder 310.Motion bar 320 have the flange 321 radially protruded, and flange 321 is placed in the cylinder chamber 311 of elastic force cylinder 310.Elastic component 330 is placed in The cylinder chamber 311 of elastic force cylinder 310 is simultaneously set along the axial direction of elastic force cylinder 310, and elastic component 330 is located at the end of flange 321 and elastic force cylinder 310 Between wall 312.Elastic force cylinder 310 is connected with any one in motion bar 320 with matrix 210, another one and detector body 100 Connection.Flange 321 is used for compression elastic piece 330 so that telescopic component 300 is stretched, and it is telescopic component 300 that elastic component 330, which is used for, Offer is driven positioned at the connection component 200 at the both ends of detector body 100 power close to each other.

Further, in the present embodiment, motion bar 320 is connected with matrix 210, elastic force cylinder 310 and detector body 100 Connection.

Further.Elastic force cylinder 310 is in the form of a column, and cylinder chamber 311 is cylindrical, and motion bar 320 is cylindrical, motion bar 320 It is coaxially disposed with elastic force cylinder 310.

Further, elastic component 330 is spring, and elastic component 330 is sheathed on motion bar 320, and elastic component 330 is connected to flange Between 321 and end wall 312.

When pulling two connection components 200 to be located remotely from each other two connection components 200, connection component 200, which can pull, to be stretched The motion bar 320 of contracting component 300, the flange 321 of motion bar 320 can compression elastic piece 330 at this time.When putting on two connection groups After the pulling force of part 200 is removed, elastic component 330 drives the flange 321 of motion bar 320 to reset, and then motion bar 320 pulls connection Component 200 simultaneously makes two connection components 200 again close to each other.

Pass through the design to telescopic component 300 so that telescopic component 300 can not only allow between two connection components 200 Further away from meet different size flange arrangement installation requirement, simultaneous retractable component 300 can also be connection component 200 provide a pulling force close to each other, to ensure that connection component 200 can firmly be sticked in flange arrangement.

Further, one end of the remote matrix 210 of motion bar 320 has scotch 322, and scotch 322 is located at elastic force The side of the remote matrix 210 of cylinder 310.Scotch 322 is used to prevent motion bar 320 further towards the side where matrix 210 Slide, prevent the end of motion bar 320 from entering the cylinder chamber 311 of elastic force cylinder 310 and influencing the normal function of telescopic component 300.Only Motion block 322 improves the stability of the work of telescopic component 300.

Further, along the axial direction of motion bar 320 and elastic force cylinder 310, scotch 322 bullet is smaller than with flange 321 The length of the cylinder chamber 311 of power cylinder 310.

The operation principle of methane detector 1000 is：When being installed, two connection groups of methane detector 1000 are pulled Part 200 is located remotely from each other two connection components 200, and the connector 220 of two connection components 200 is corresponded to and is sticked in flange arrangement Nuts and bolt head.After unclamping connection component 200, connection component 200 mutually leans under the pulling force effect of telescopic component 300 Closely, so as to stably be sticked in the nuts and bolt head of flange arrangement.If the connector 220 of two connection components 200 does not have It is accurately corresponding with nuts and bolt head, can be rotatablely connected first 220 make section be regular hexagon blind hole 221 with nut and spiral shell The accurate correspondence of bolt head is so that nuts and bolt head can smoothly be caught in blind hole 221.Until two connectors 220 are completely, surely Surely it is sticked in nuts and bolt head.

When being dismantled, above-mentioned flow is carried out to opposite operation.

In general, methane detector 1000 disassembles and installs easily, fast, can be dismantled and be installed at any time To other test positions.Connection component 200 is hardly damaged, high recycling rate, and it is overall to substantially prolongs methane detector 1000 Service life.Since telescopic component 300 makes the distance between two connection components 200 adjustable so that methane detector 1000 It can be used on the flange arrangement of different size, expand the scope of application, flexible adjustment is easy to use.
