Abstract
The utility model discloses an eye sight protection instrument which comprises a top cover, a lens, a shell and a base, wherein the shell is fixedly provided with a timer, an operation panel, a power supply key and an eject key, and a lock control mechanism, a circuit board, a power supply and a damping type eject mechanism are arranged in the base. The damping type eject mechanism is composed of a pin shaft, a slave connecting rod, an intermediate shaft, a master connecting rod, a torsion spring, a shaft base, a washer, a check ring and a rotary shaft, wherein the pin shaft is connected to the lower end of the lens, the slave connecting rod is connected with the master connecting rod through the intermediate shaft, and the end of the master connecting rod is clamped with the torsion spring and is stringed on the rotary shaft which is sheathed in the shaft base with damping grease and is tightened by the washer and the check ring. The utility model has the advantage of slow and steady ejection of the lens, etc.
Description
Technical field:
This utility model relates to a kind of eye eyesight protection instrument.
Background technology:
Present eye eyesight protection instrument, it is made of top cover, camera lens, housing, base etc.On housing, be installed with timer, guidance panel, power key, eject key.Camera lens is installed under the top cover, can also can eject housing in the retraction housing.Lock control mechanism, ejecting mechanism, wiring board, power supply are installed in the base.During use; can press eject key and make camera lens eject housing, press power key simultaneously, people's eyes are watched the even laser speckle of certain wavelength that camera lens sends; play the purpose of anti-eye strain and vision protection, push top cover behind the use certain hour camera lens is retracted in the housing.Because the ejecting mechanism of present eye eyesight protection instrument, employing be the ejection that torsionspring provides potential energy to control camera lens, because its elasticity is big, and rising or falling speed is fast, can impact to camera lens, the time has been grown camera lens and has damaged easily in actual the use.
The utility model content:
The purpose of this utility model provides that a kind of camera lens ejects slowly, the instrument of eye eyesight protection stably.
To achieve these goals, this utility model comprises: top cover, camera lens, housing, base, be installed with timer on the housing, guidance panel, power key, eject key, lock control mechanism is installed in the base, wiring board, power supply, the damp type ejecting mechanism, the damp type ejecting mechanism is by bearing pin, slave connecting rod, jackshaft, master connecting-rod, torsion spring, axle bed, packing ring, back-up ring, rotating shaft constitutes, bearing pin is connected to the camera lens lower end, slave connecting rod is connected by jackshaft with master connecting-rod, the termination card of master connecting-rod has torsion spring and is through in the rotating shaft, and rotating shaft is inserted in the axle bed that contains damping grease and is tightened with packing ring and back-up ring.Like this, camera lens is before ejection, ejecting mechanism is as " Z " shape, be in the energy storage state, in the camera lens ejection process, the ejecting mechanism shape releases energy to " L " deformationization from " Z " shape, control rotating shaft and the gap of axle bed and the effect of damping grease, can control the torsion spring energy and discharge slowly, camera lens is ejected stably with slow speed.
Description of drawings:
Below in conjunction with accompanying drawing this utility model is described in further detail.
Fig. 1 is an external structure sketch map of the present utility model.
Fig. 2 is a base internal components arrangement sketch map of the present utility model.
Fig. 3 is the ejecting mechanism structural representation.
The specific embodiment:
By Fig. 1, Fig. 2, Fig. 3 as can be known, this utility model comprises: top cover 1, camera lens 2, housing 7, base 8, be installed with timer 3, guidance panel 5, power key 6, eject key 4 on the housing 7, lock control mechanism 9, wiring board 12, power supply 13, damp type ejecting mechanism 11 are installed in the base 8.The damp type ejecting mechanism is made of bearing pin 14, slave connecting rod 15, jackshaft 16, master connecting-rod 17, torsion spring 18, axle bed 19, packing ring 20, back-up ring 22, rotating shaft 21, and bearing pin 14 is connected to the camera lens lower end, and axle bed 19 is installed on the interior fixing head 10 of base.Slave connecting rod 15 is connected by jackshaft 16 with master connecting-rod 17, and 15 of bearing pin 14 and slave connecting rods are riveted joint.The termination card of master connecting-rod 17 has torsion spring 18 and is through in the rotating shaft 21, torsion spring 18 1 ends are stuck on the master connecting-rod 17, the other end is placed on the fixing head 10, and master connecting-rod 17 is riveted joint with rotating shaft 21, and rotating shaft 21 is inserted in the axle bed that contains damping grease and is tightened with packing ring 20 and back-up ring 22.
