Abstract
The utility model discloses an automatic unfastening device for a sensor. The device comprises a shell, a sleeve, a connecting rod, a magnetic conduction sheet, a limit position plate and a magnet, wherein the sleeve is arranged at one end of the shell and connected with the shell; one end of the connecting rod is connected with the magnetic conduction sheet, and the other end of the connecting rod passes through the central hole of the sleeve and extends into the shell; a spring is sleeved on the other end of the connecting rod; the magnet is fixed on the limit position plate, is arranged at a point to be tested, is a certain distance away from the magnetic conduction sheet and corresponds to the magnetic conduction sheet, so that the magnet can adsorb the magnetic conduction sheet; a stay cord is led out from the point to be tested and is clamped on a contact surface between the magnetic conduction sheet and the sleeve through the limit position plate, the magnet and the connecting rod in turn; and a stay cord sensor is fixed at one end, which is far away from the sleeve, of the shell. Since the suction of the magnet is greater than the elastic force of the spring in a limit measuring range, the stay cord is automatically separated from the sensor. When the test point stay cord is automatically separated in the limit measuring range, the stay cord sensor is kept in the limit measuring range and does not rebound rapidly, so that a test point and the sensor are protected.
Description
Technical field
The utility model relates to the automatic wire-off device of a kind of sensor, the protective device of especially a kind of backguy sensor automatic off-line under the situation of limit range.
Background technology
At present, in the occasion of using the backguy displacement transducer, all be the displacement transducer that the distance of pre-estimating detection is earlier selected suitable range then, guarantee to detect distance in the range ability of displacement transducer.But the outrange problem will take place in the occasion at inestimable occasion of some ranges or easy something unexpected happened.The backguy sensor if backguy can not be thrown off automatically, will cause damage to sensor and measuring point under the state of limit range.
The utility model content
The purpose of this utility model provides the automatic wire-off device of a kind of sensor, and this device can be under backguy sensor limit range state, the automatic and sensor disengaging of the backguy of measuring point, thus sensor and measuring point are shielded.
For reaching above purpose, solution of the present utility model is:
The automatic wire-off device of a kind of sensor, it comprises housing, sleeve, connecting link and magnetic conduction sheet, sleeve is located at housing one end, and links to each other with housing; Connecting link one end links to each other with magnetic conduction sheet, and the other end passes the sleeve center pit and stretches in the housing, and this other end is arranged with spring; It also comprises extreme position plate and magnet, and magnet is fixed on the extreme position plate, is located at the tested point place, thus adsorbable this magnetic conduction sheet of separated by a distance with magnetic conduction sheet and the corresponding magnet of magnet.
Described spring is compressed on the connecting link by setting nut.
The described connecting link end that links to each other with magnetic conduction sheet is provided with center pit.
Described extreme position plate and magnet are provided with center pit.
It also comprises backguy sensor, backguy, and backguy is drawn from tested point, is sandwiched on the surface of contact of magnetic conduction sheet and sleeve by extreme position plate, magnet, connecting link successively; The backguy sensor is fixed in housing away from sleeve one end.
Owing to adopted above technical scheme, the utlity model has following beneficial effect: the backguy sensor is under limit range state, and the backguy meeting breaks away from measuring point automatically, and test point is not had additional reaction.

Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
In Fig. 1, housing 10 links together with sleeve 7, and threaded rod 8 one ends connect magnetic conductive iron sheet 6, after the other end passes the center pit of sleeve 7, in the termination setting nut 11 is installed spring 9 is compressed on the threaded rod 8.Under the effect of spring 9 elastic force, magnetic conductive iron sheet 6 is close together with sleeve 7.
In Fig. 2, the backguy 2 that measuring point 1 is drawn pass extreme position plate 3 and the center pit of gib screw 5 that magnet 4 and extreme position plate 3 are fixed together after, enter the center pit of threaded rod 8, and stretch out from the side, backguy 2 is sandwiched on the surface of contact of magnetic conductive iron sheet 6 and sleeve 7, and backguy sensor 13 is fixed on the other end of wire-off device housing 10 by attachment screw 12.When reaching the limit of range; housing 10 and sleeve 7 can not continue to move again; and magnetic conductive iron sheet 6 can be inhaled in the past by magnet 4; magnetic conductive iron sheet 6 will separate with sleeve 7; being clipped in the backguy 2 that connects measuring point 1 between the two will throw off; protected measuring point 1, backguy displacement transducer 13 is parked in limit range position by the suction of magnet and backguy sensor 13 has been protected in not resilience fast.
The utility model guarantees that by spring force the backguy sensor links to each other with the backguy of measuring point in normal range ability, in limit range ability, guarantee that greater than spring force measuring point backguy and sensor break away from automatically by magnet suction.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the utility model is not limited to the embodiment here, and those skilled in the art should be within protection domain of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
