Description
Technical field
The present invention relates to a kind of large, medium and small type optical instrument lens cap device.
Background technology
Because instrument usually is used to the outfield, after optical instrument is used up,, prevent the piping and druming of dust storm and the erosion of wave for the part that keeps the instrument the inside cleanliness of optical element particularly, on optical instrument, add lens cap.In the past, lens cap on the instrument all is directly to adopt coarse thread to be connected with the lens barrel of optical instrument or light shield, when its shortcoming is installation, if lens cap is not aimed at the lens barrel of optical instrument or the screw thread of light shield, so, will tilt when the lens barrel of lens cap and optical instrument or the threaded engagement on the light shield, will it could be aimed at several times repeatedly during installation, the special lens barrel or the relative aperture of light shield greatly time the when optical instrument, contradiction is more outstanding.For the staff can be taken off lens cap at short notice quickly and easily, after instrument used, the staff can be installed in lens cap on the instrument again fast and accurately easily, has designed a kind of fastening lens cover device.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of installation fastening lens cover mounting means simply fast, to satisfy the requirement of contemporary optics instrument.
The present invention solves the solution that its technical matters adopts: fastening lens cover device is characterized in that: comprising: collar, outer cover, bail, lens cap, handgrip; The screw thread of collar by an end is screwed on the lens barrel or light shield of optical instrument, has two slots that are mutually 180 ° at the other end of collar; Again bail is screwed on the lens cap by screw thread, for convenience the installation of lens cap; With two one or two hand rivet(ing)s on lens cap.
Two slots that are mutually 180 ° that have on the described collar are the L type, make bail screw in behind the slot as are subjected to extraneous vibration or can oneself come off when impacting.
The outer survey is equipped with outer cover around described collar and the bail, makes its fastening lens cover device more attractive in appearance.
The use of above-mentioned fastening lens cover device, during installation, the two hand-tight handles of holding on the lens cap embed the bail on the lens cap in the slot of collar, rotating mirror skull gently, bail screws in the collar along gap, and lens cap will be fastened on the collar; When needs take off lens cap device, the two hand-tight handles of holding on the lens cap, the rotating mirror skull, bail screws out the collar lens cap along slot and takes off.
The present invention has following advantage compared with prior art:
1, fastening lens cover device of the present invention has two oblique slots that are mutually 180 ° on the collar of selecting for use, and these two slots all are the L types, makes its bail screw in behind slot as is subjected to extraneous vibration or can oneself come off when impacting;
2, fastening lens cover device of the present invention has two threaded holes on the end face of lens cap, utilize threaded hole that two bails are fixed on the lens cap, can be easy during operation, fast bail is embedded in the slot of collar accurately;
3, fastening lens cover device of the present invention has two handles, more convenient operation when making its installation or unloading lens cap in the front end riveting of lens cap;
4, fastening lens cover device of the present invention is surveyed outside around collar and the bail outer cover is installed, and makes its fastening lens cover device more attractive in appearance.
Description of drawings:
Fig. 1 is a fastening lens cover device;
Fig. 2 is the view of collar slot in the fastening lens cover device; Fig. 2 a is the front view of collar slot in the fastening lens cover device, and Fig. 2 b is the side view of collar slot in the fastening lens cover device;
Among the figure: 1 collar, 2 outer covers, 3 bails, 4 lens caps, 5 handles, 6 is slot.
Embodiment
The present invention is described in detail below in conjunction with the drawings and the specific embodiments.
The fastening lens cover device of present embodiment comprises as shown in Figure 1: collar 1, outer cover 2, bail 3, lens cap 4, handle 5.
The screw thread of collar 1 by the one end is screwed on the lens barrel or light shield of optical instrument, and the other end of collar 1 has two oblique slots 6 of L type that are mutually 180 °.In addition, again bail 3 is screwed on the lens cap 4 by screw thread, the installation of lens cap 4 for convenience, with two handle 5 rivetings on lens cap 4.In the outfield after optical instrument is used up, in the time of need being installed in fastening lens cover on the instrument, the two hand-tight handles of holding on the lens cap 45, slot on bail 3 alignment collar 1 on the lens cap 4, make in its slot 6 that embeds collar 1, the front view of collar slot and side view are shown in Fig. 2 a and Fig. 2 b in the fastening lens cover device, and the rotating mirror skull 4 gently, screw 3 screws in the collar 1 along slot 6, and lens cap 4 will be fastened on the collar 1; In the outfield, when needs reuse optical instrument, lens cap device need be taken off, only need the two hand-tight handles of holding on the lens cap 45, rotating mirror skull 4, bail 3 screws out collar 1 along slot 6.Have two slots that are mutually 180 ° on the collar 4, and these two slots 6 all become the L type, afterbody becomes 100 ° with level; In addition, attractive in appearance for instrument, outer cover 2 is threaded by the other end of screw thread with collar 1, externally will can't see bail 3.Exactly, outer cover 2 only is the decoration parts of fastening lens cover device.
