Abstract
The invention relates to a camera lens which is not easy to be wet. The technology is: the camera window without the water has a lens which is embedded in the tubular lens seat which is located in the camera shell by the bearing; a gear is fixed in the external circle surface of the lens seat which is meshed with the small gear in the output axis of the micro electric engine to drive the lens seat and the lens rotating quickly. The circumference of the lens is embedded in the inside circle surface of inner circle and fixed by the annulus nut. The grease seal is installed between the tubular lens seat and the camera shell and the bearing is the ball bearing.
Description
Technical field
The present invention relates to a kind of camera lens, especially be difficult for being stained with the camera lens of water.
Background technology
Because gather the needs of news, gamma camera is worked under the harsh climate condition through regular meeting.When taking, be stained with the sleet water droplet on the camera lens easily, have a strong impact on work thereby the image blurring of make gathering is unclear in the sleet sky.Though gamma camera is furnished with special-purpose lens protective cover (lens protective cover 17 shown in Figure 5 adopts threaded engagement to be connected with the casing of gamma camera 4) on camera lens; But the main effect of lens protective cover is the stray light around avoiding enters camera lens, prevents the accidental injury of external object to camera lens, avoids the person's of videotaping finger false touch camera lens surface; The effect of blocking sleet but is not very good, and the situation that the sleet water droplet descends slowly and lightly to camera lens often is difficult to avoid, thereby has influenced normally carrying out of production work.
Summary of the invention
Technical matters to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of camera lens is provided, and this camera lens should have and is difficult for being stained with water, volume features of smaller, and simple in structure, is easy to make.
The technical solution used in the present invention is: camera anhydrous viewing window, have an eyeglass, and this eyeglass is inlaid on the tubular eyeglass seat, and the eyeglass seat is positioned on the gamma camera casing by bearing; Also fix a gear on the outer circumference surface of tubular eyeglass seat, other has pinion wheel and described gearing mesh on the micromachine output shaft, to order about described eyeglass seat and eyeglass quick rotation.
The periphery of described eyeglass is inlaid in the inner circumferential surface of tubular eyeglass seat, and fixes with circular nut spinning.
Between described tubular eyeglass seat and the gamma camera casing oil sealing that waterproof is used is housed.
Described bearing is a ball bearing.
Only need energized to make micromachine rotate when the present invention uses, thereby drive the eyeglass high-speed rotation, change more than 1500 commentaries on classics of scooter per minute; (fall shown in Figure 1 eyeglass left side) if extraneous sleet water droplet is fallen on the eyeglass this moment, and the centrifugal force that promptly is rotated generation drives and flows to the circumferential edge edge of eyeglass, and throws away eyeglass after crossing circular nut; Thereby make eyeglass can remain anhydrous state.
Use the present invention, can make eyeglass be in anhydrous state all the time; Can guarantee that not only gamma camera is not subjected to climatic influences, guarantee the image quality of picked-up, and designed device volume be less, does not increase shared space substantially, thereby bring great convenience for the use of gamma camera.In addition, designed apparatus structure is simple, and is easy to manufacture, so cost is also low.

Fig. 3, Fig. 4 are respectively the two kind mounting means synoptic diagram of the present invention on gamma camera.
Fig. 5 is the synoptic diagram that existing lens protective cover is connected with the gamma camera casing.
Embodiment
As seen from the figure: this camera anhydrous viewing window has an eyeglass 10, after this eyeglass is inlaid on the eyeglass seat 2, outside the left side is exposed to; As shown in Figure 1, the eyeglass seat is tubular, and its axial two ends directly communicate, so that the passing through of the visual light of taking the photograph (entering from the left end of eyeglass seat); The inner circumferential surface of eyeglass seat is made the height ladder and the screw thread that do not wait, and the circumferential outer edge of described eyeglass is slotting to be embedded in after the ladder place of tubular eyeglass seat, cooperates and eyeglass 10 spinning are fixed with described being threaded into circular nut 1 again.Described circular nut 1 also is shaped on inclined surface (as shown in the figure, the cross section is trapezoidal, also can be triangle), so that the throwing away of sleet water droplet.
Described tubular eyeglass seat 2 is positioned on the casing of gamma camera by bearing; For reducing the resistance of motion, described bearing adopts ball bearing.Concrete mounting means is as shown in Figure 1: the outer circumference surface of tubular eyeglass seat 2 is embedded on the inner ring of bearing 6, and the outer ring of bearing 6 is then inserted and is embedded on the casing of gamma camera 4, and with jump ring 5 stationary positioned.
Also fix a gear 8 on the outer circumference surface of tubular eyeglass seat 2, this gear is fixed on by key 7 on the outer circumference surface of tubular eyeglass seat 2, and axis direction is also with jump ring 9 location; Other has pinion wheel 12 and described gear 8 engagements on micromachine 11 output shafts, rotates to order about described eyeglass.The power supply of motor can directly adopt the power supply of gamma camera.Among Fig. 2 as can be known: because motor and respective pinions thereof be housed, therefore form one outstanding 14 in the lower end of tubular eyeglass seat.Because volume that should be outstanding is less, so its influence can be ignored.
In addition, the oil sealing 3 (directly outsourcing) that waterproof is used is housed between described tubular eyeglass seat and the gamma camera casing,, keeps the drying of camera lens inside to avoid entering of extraneous water.
Because the lens protective cover 17 of existing gamma camera adopts screw thread to screw mode with being connected of gamma camera; So the mounting means of the present invention on gamma camera can have two kinds.The one, be fixedly mounted on as previously described on the gamma camera casing, mode-gamma camera 4 front ends promptly shown in Figure 4 are camera anhydrous viewing windows 16, lens protective cover 17 still screws mode with screw thread and is connected with the gamma camera casing.The 2nd, camera anhydrous viewing window 16 is fixedly mounted on the lens protective cover 17, and lens protective cover 17 adopts screw thread to screw mode with the gamma camera casing again to be connected mode promptly shown in Figure 3 then.
Claims (2)
1. camera anhydrous viewing window has an eyeglass (10), and the periphery of this eyeglass is inlaid in the inner circumferential surface of tubular eyeglass seat (2), and fixes with circular nut (1) spinning; The eyeglass seat is positioned on video camera (4) casing by bearing (6); It is characterized in that also fixing a gear (8) on the outer circumference surface of eyeglass seat, other has pinion wheel (12) and described gearing mesh on the micromachine output shaft, to order about described eyeglass seat and eyeglass quick rotation; Between described tubular eyeglass seat (2) and video camera (4) casing oil sealing (3) that waterproof is used is housed.
