Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The card-type lens cover device of this embodiment is as figure 1 As shown, it includes: collar 1, outer cover 2, staple 3, lens cover 4, and handle 5.

[0018] The collar 1 is screwed onto the lens barrel or light hood of the optical instrument through the thread at one end, and the other end of the collar 1 is provided with two L-shaped oblique grooves 6 forming 180° with each other. In addition, the staple 3 is screwed onto the lens cover 4 through threads, and two handles 5 are riveted on the lens cover 4 to facilitate the installation of the lens cover 4 . After the optical instrument is used in the field, when it is necessary to install the card-type lens cover on the instrument, hold the handle 5 on the lens cover 4 tightly with both hands, and the staple 3 on the lens cover 4 is aligned with the groove on the collar 1 , so th...

Abstract

The invention discloses a cassette lens cap device which comprises a closing ring, an outer housing, an attachment clip, a lens cap and two handlebars; the closing ring is screwed onto a lens cone or a lens hood of an optical instrument by thread arranged at one end, and the other end of the closing ring is provided with two L-shaped grooves which mutually form the angle of 180 degrees; then, the attachment clip is screwed onto the lens cap by the thread in order to be convenient for the installation of the lens cap; the two handlebars are riveted on the lens cap; the outer side of the periphery of the closing ring and the attachment clip is provided with the outer housing, so that the cassette lens cap device is more beautiful; when in installation, the handlebars on the lens cap are firmly held by the two hands, the attachment clip on the lens cap is embedded into the groove of the closing ring, the lens cap is lightly turned, the attachment clip is screwed into the closing ring along a notch, and the lens cap is closely fixed on the closing ring; when the lens cap device is needed to be taken down, the handlebars on the lens cap are firmly held by the two hands, the lens cap is turned, the attachment clip is screwed out of the closing ring along the groove, and the lens cap is taken down; the device has simple operation and convenient use.

Description

technical field [0001] The invention relates to a large, medium and small optical instrument lens cover device. Background technique [0002] Because the instrument is often used in the field, when the optical instrument is used up, in order to keep the parts inside the instrument, especially the cleanliness of the optical parts, and prevent the blowing of wind and sand and the erosion of waves, a lens cover is added to the optical instrument. In the past, the lens cap on the instrument and the lens barrel or hood of the optical instrument were directly connected by coarse thread. , the lens cover will be inclined when it engages with the lens barrel of the optical instrument or the thread on the hood, and it must be aligned several times during installation, especially when the lens barrel or hood of the optical instrument has a relatively large diameter. more prominent. In order to allow the staff to quickly and conveniently remove the lens cover in a short time, and aft...
