Description
Technical field
The present invention relates to a kind of pick-up unit, particularly relating to a kind of pick-up unit for detecting fuselage degree of tilt.
The present invention relates to a kind of laser alignment instrument with this pick-up unit.
Background technology
People obtain level or vertical laser beam by laser alignment instrument usually.But in concrete use procedure, the fuselage of laser alignment instrument can not guarantee that the moment is in the state of abswolute level thus have impact on the bearing accuracy of laser beam.At this moment, automatic calibration is carried out with regard to needing by the pendulum mass that can be in vertical state under weight effect.Under normal circumstances, the free movable range of pendulum mass is (namely the extreme value of the pendulum angle of pendulum mass is-5 ° or+5 °) between-5 ° to+5 °, when laser alignment instrument put too tilt time, pendulum mass no longer will reach normal vertically state, at this moment the detection system of laser alignment instrument will measure exception, and give the alarm, laser collimator is thought highly of and is newly put to rational position by reminding user.
The concrete structure of the pick-up unit in existing product has been shown in Fig. 1.This pick-up unit includes the spring 2 on the circuit board 1 that is arranged on and fixes with the support of laser alignment instrument, and the sheet metal 3 with circular perforations be fixed on the pendulum mass of laser alignment instrument, this spring 2 is through the circular perforations of sheet metal 3, and sheet metal 3 swings along with the swing of pendulum mass.In concrete use procedure, when the pendulum mass of laser alignment instrument swings to predetermined angle, spring 2 just will contact with sheet metal 3 and realize being electrically connected, and produces electric signal by circuit board process, feed back to user, laser collimator is thought highly of and is newly put by reminding user.Meanwhile, this spring 2 can also play and prevent frequent touching from causing the dysgenic effects such as deformation.
But this existing pick-up unit Problems existing is, in the assembling process of reality, the scope being difficult to the pendulum angle guaranteeing to preset is consistent with the actual angular range that can detect.This is because the production of the parts such as the spring 2 of existing pick-up unit, sheet metal 3 and assembling all comparatively inconvenience, easily produce deviation, and any small deviation all can cause the scope of the pendulum angle preset and the actual angular range that can detect inconsistent.Such as, the angle that the freedom of the pendulum mass preset is swingable is+5 °, and in fact when pendulum mass swings to+4 °, spring 2 has just contacted with sheet metal 3 and has realized being electrically connected, thus give the alarm in advance, at this moment just there is larger problem in the accuracy of the detection of pick-up unit, and it reduces the scope of the automatic calibration of pendulum mass, thus need again to debug assembling.In the prior art, owing to have employed pick-up unit as shown in Figure 1, occur the scope of pendulum angle preset and the inconsistent situation of the actual angular range that can detect very general.Except detection accuracy is not high, existing pick-up unit is made up of parts such as spring 2, sheet metals 3, and this apparatus structure is comparatively complicated, cost is high.
Therefore, how to provide a kind of can guarantee the scope of the pendulum angle preset consistent with the actual angular range that can detect, high, the simple pick-up unit of structure of detection accuracy becomes problem demanding prompt solution.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the object of the present invention is to provide a kind of can guarantee the scope of the pendulum angle preset consistent with the actual angular range that can detect, high, the simple pick-up unit of structure of detection accuracy.
The invention discloses a kind of pick-up unit, be applied in laser alignment instrument, described pick-up unit comprises conductive rubber and becket, and wherein, described conductive rubber is arranged on the lower end of the pendulum mass of described laser alignment instrument; On inwall bottom the support that described becket is arranged on described laser alignment instrument; When the pendulum mass of described laser alignment instrument swings freely to a predetermined angle, described conductive rubber just contacts with described becket and realizes being electrically connected, and produces the electric signal for reporting to the police.
Preferably, described conductive rubber is the circular lower end being close to the pendulum mass of described laser alignment instrument.
Preferably, described pick-up unit also has circuit board, and described conductive rubber contacts with described becket when realizing being electrically connected and produces electric signal by described circuit board.
