Optical disc positioning device on packaging box

Abstract

The invention relates to an optical disc positioning device on a packaging box. The optical disc positioning device comprises a first half box body, wherein a second half box body is connected to oneside of the first half box body by virtue of a hinge, first spring columns are fixedly arranged on the top and at the bottom of an inner cavity of the first half box body, and a third half box body isconnected to one end, which is far from the first half box body, of the first spring columns. When an optical disc is taken, the condition of bending or even breaking cannot occur, a good protectionfunction is realized, and the space utilization rate is high; the first half box body and the third half box body are connected by virtue of the first spring columns, so that the shock absorption andbuffer capability of the third half box body is increased, and the optical disc is prevented from being damaged by severe vibration; a second spring column and a semicircular rubber block are arranged, so that the anti-falling performance of the first half box body and the second half box body is improved, and the service life of the device is prolonged; and the optical disc is put on the top of afirst sponge mat, the optical disc is fixed from left to right by virtue of a plastic limiting column, and the optical disc is extruded and fixed up and down by virtue of a limiting nut.

Description

technical field [0001] The invention relates to a disc positioning device on a packaging box, belonging to the technical field of packaging equipment. Background technique [0002] At present, there are mainly two kinds of common optical disc packaging boxes, one is a bag-type packaging box, and the other is a box-type packaging box. The bag-type packaging box is soft in texture, weak in protection strength, and has a large wear on the surface of the optical disc. , generally only used for packaging ordinary optical discs. The box body of the cassette-type optical disc packaging box has a certain strength, and can avoid direct contact between the box body and the surface of the optical disc substrate, so it can better protect the optical disc. The existing cassette-type optical disc packaging box All adopt the middle fixing method, which is provided with a clamping boss in the middle of the box body to match the center hole of the disc, the disc is fixed by the clamping prot...

Problems solved by technology

[0002] At present, there are mainly two kinds of common optical disc packaging boxes, one is a bag-type packaging box, and the other is a box-type packaging box. Due to its soft texture, the bag-type packaging box has weak protection strength and has a large wear on the surface of the optical disc. , generally only used for packaging ordinary optical discs. The box body of the cassette-type optical disc packaging box has a certain strength, and can avoid direct contact between the box body and the surface of the optical disc substrate, so it can better protect the optical disc. The existing cassette-type optical disc packaging box All adopt the middle fixing method, which is provided with a clamping boss in the middle of the box body to match the central hole of the disc. The clamping boss and the central hole of the optical disc have a relatively tight clamping strength. This design causes the disc surface to undergo a large elastic deformation to remove the disc from the clamping protrusion when the optical disc is picked up. For frequent As far as the optical disc is used, it may even be bent or broken due to excessive elastic deformation, which will lead to serious consequences such as unreadable data and data loss. Therefore, further improvement is needed.
