The working principle of the invention is as follows:
when the pen container is used, the conical sleeve 3 at the end part of the pen container 1 is aligned to a crack to be measured, then the pulling piece 2 is pushed, at the moment, the pulling piece 2 drives the supporting ring 203 to move, the buffer corrugated pipe 204 is extruded in the process that the supporting ring 203 moves downwards, and because the air in the buffer corrugated pipe 204 cannot flow out, the supporting ring 203 drives the supporting plate 205 to move through the buffer corrugated pipe 204, and then the driven rod 102 moves along with the supporting ring 203;
the probe 4 slowly stretches into the crack, after the end of the probe 5 touches the inside of the crack, data are read from the control panel, if the deepest point of the crack needs to be found, the probe moves along the crack, the poking plate 2 is slowly pushed out in a probing mode, if the probe 4 continuously stretches out, the probe does not reach the deeper part of the crack, if the probe 4 touches a gentle slope during moving, the data which are just measured are the deepest part of the crack;
In order to prevent the probe tube 4 from being damaged due to excessive force when the probe 5 contacts the blocking part in the reverse crack, the probe tube 4 is deflected by force in whole, then the air bag 215 is compressed, the extruded gas in the air bag 215 enters the interior of the reverse inner supporting tube 206 along the conducting tube 208, so that the supporting block 304 moves upwards, meanwhile, the contact block 503 contacts the inner wall of the crack due to the contact of the probe 5 with the inner wall of the crack and the traction force caused by the movement, the contact block 503 is relatively static, the probe 5 is far away from the contact block 503 under the action of force, the passive barrel 502 is separated from the clamping sleeve 501, and the center rod 303 is not clamped by the clamped ball;
Therefore, two adjacent supporting cylinders on the outer surface of the probe tube 4 are not supported by the supporting blocks 304, so that the probe tube 4 can be freely bent, excessive damage to the probe tube 4 due to force is avoided, meanwhile, the passive plug 301 moves upwards along with the movement of the central rod 303, and the locking sleeve 212 is driven by the tilting rod 213 to be no longer sleeved on the outer surface of the clamping plate 216;
the passive plug 301 drives the push rod 305 to move, the push rod 305 pushes the communication sleeve 406 to move upwards, so that the through hole on the outer surface of the movable sleeve 404 is exposed, the air inlet of the switching sleeve 401 cannot flow in air, and under the action of the air pressure in the buffer corrugated pipe 204, the air flows out along with the through hole on the outer surface of the movable sleeve 404, at the moment, the support plate 205 can move up and down, and the probe 4 can also move up and down, so that the possibility of damage of the probe 5 is further avoided;
At this time, the operator can obviously feel the deformation of the pouring probe 4 and move in the opposite direction, so that the pen container 1 and the end part of the probe 4 are positioned on the same axis, the supporting block 304 and the communicating sleeve 406 are restored to the initial state at this time, then the movable plug 107 moves upwards under the action of the elastic force of the return spring 106, the upper end of the clamping post 210 presses the passive sleeve 103 downwards, at this time, the passive sleeve 103 moves in the opposite direction, the clamping post 210 does not continuously clamp the passive sleeve 103, the air inside the air storage tube 101 is extruded along with the upward movement of the movable plug 107, the air flows into the communicating sleeve 406 along with the output tube 104, and then flows into the buffer corrugated tube 204, so that the effect of re-inflating the buffer corrugated tube 204 is realized.
After the measurement is finished, the pulling piece 2 is pushed back, and as the supporting plate 205 and the following parts have dead weight, the supporting ring 203 drags the air release rod 402 to move through the movable ring 209, at this time, the sealing cover 403 at the end part of the air release rod 402 moves to the outside of the switching sleeve 401, the probe tube 4 is supported in the recovery process, so that the outer surface of the probe tube 4 can continuously extrude the air bag 215, the clamping plate 216 and the clamping sleeve 217 are not clamped on the outer surface of the guide rod 202 any more, the probe tube 4 is supported and a thrust force is slightly applied towards the direction of the pen container 1, so that a reaction force is generated, the decompression ring 211 is not sleeved on the outer surface of the clamping sleeve 217 any more, and then the recovery of the probe tube 4 and the measurement of the crack depth are realized.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art who is skilled in the art to which the present invention pertains should cover the scope of the present invention by equally replacing or changing the technical scheme and the inventive concept thereof.
