Abstract
The utility model discloses a hard disk digital video recorder capable of preventing the accidental draw-out. The hard disk digital video recorder includes a digital radio recorder box body and a hard disk box. The inside of the digital video recorder box body is provided with a hard disk box groove which can hold the hard disk box. An upper cover is arranged on the hard disk box groove. The front end of the digital video recorder box body is provided with a front panel. One side of the front panel is provided with an electronic lock. A rotatable side wall of the electronic lock is provided with a lock pin which is perpendicular to the rotatable side wall and can rotate with the rotatable side wall. A corresponding side wall of the hard disk box is provided with a lock pin hole which cooperates with the lock pin of the electronic lock. The hard disk digital video recorder adopts the dual-protection mode in which the electronic lock and a manually screwed screw are used, so the charged draw-out of the hard disk box is prevented when an accident occurs, and consequently the vehicle hard disk digital video recorder and the hard disk box can not be damaged, and the recorded video is protected. The hard disk digital video recorder can prevent the accidental charged draw-out of the hard disk box and the damage of the vehicle hard disk digital video recorder and the hard disk box, and has the advantages of simple structure and low cost.

At some in particular cases, the clerical worker needless to say vehicle-mounted hard disk videocorder deactivate state, do not turn off power supply, also just be eager to pull down wherein hard-disk cartridge in when work at vehicle-mounted hard disk videocorder, will damage vehicle-mounted hard disk videocorder and hard-disk cartridge like this, destroy the image that has recorded.
Summary of the invention
The purpose of this utility model is to provide a kind of hard-disk cartridge that can prevent to be extracted, guarantee the vehicle-mounted hard disk videocorder that vehicle-mounted hard disk videocorder and hard-disk cartridge are damaged, not simple in structure by accident when charged.
The purpose of this utility model is achieved in that
A kind of anti-unexpected DVR that extracts comprises video recorder box body and hard-disk cartridge, is processed with in the described video recorder box body for the hard-disk cartridge groove of placing hard-disk cartridge, is covered with loam cake on the described hard-disk cartridge groove, and video recorder box body front end is provided with front panel; In one side of described front panel electronic lock is installed, the rotation sidewall of described electronic lock is provided with rotating the lock pin that sidewall is vertical and can rotate with the rotation sidewall, is processed with the lockpin hole that cooperates with the lock pin of electronic lock on the respective side walls of described hard-disk cartridge.
As a kind of optimal way, be processed with front clamp screw on the front clamp of described hard-disk cartridge, the below is processed with the front panel screw in the middle of the described front panel, also is provided with a hand tighten screw, and this hand tighten screw passes front clamp screw hole and the front panel screw is installed in hard-disk cartridge in the hard-disk cartridge groove.
Concrete, be provided with two contacts that mutually electrically conduct on the described electronic lock, described two contacts when the lock pin of electronic lock cooperates the position of the lockpin hole of locking with wire two utmost point electrical communication, when other position and the disconnection of wire two utmost points.
The utility model is that electronic lock has been installed in the left side of in front plate; insert by the lock pin on the electronic lock in the lockpin hole of hard-disk cartridge; pin from the side hard-disk cartridge; and hard-disk cartridge is installed on the front panel by hand tighten screw again; it is the method that the utility model has adopted " electronic lock+hand tighten screw " duplicate protection; prevent hard-disk cartridge when unexpected situation occurs not by charged extraction, thereby guaranteed that vehicle-mounted hard disk videocorder and hard-disk cartridge are not damaged, protected the image that has recorded.Therefore, the utlity model has and to prevent that hard-disk cartridge from being extracted, guaranteeing the advantage that vehicle-mounted hard disk videocorder and hard-disk cartridge are damaged, simple in structure, not with low cost by accident when charged.
