Specific embodiment

Illustrate that the utility model is described in further detail below in conjunction with Figure of description.

As illustrated, this digital hard disc video recorder, including chassis base 4, setting mainboard 6, hard disk 7, machine in chassis base 4 It is equipped with the panel 2 being engaged by clamping with it on front side of bottom seat 4 and is fixed by screw locking, chassis base 4 rear side cooperation sets Put the postnotum 5 being engaged by clamping with it, chassis base 4 top is equipped with lid 1, two groups of chassis base 4 bottom surface setting is inside Convex closure hole 401, hard disk 7 passes through fixed screw and one of which inside convex closure hole 401 and is spirally connected fixation, another set inside convex closure hole 401 is reserved switching fixing hole.USB opening 201 is arranged on panel 2, in client using more fast square with debugging enironment Just.Panel 2 inner side setting buckle reserves opening 202, and switching for follow-up cabinet provides Multiple strategies, simultaneously also can be at follow-up group Load onto saving installation work-hour.Described inside convex closure hole 401 has hardy hole opening, and chassis base 4 arranges 8 inside convex closures Hole 401, hard disk 7 passes through fixed screw and wherein 4 inside convex closure holes 401 and is spirally connected fixation, and in addition 4 inside convex closure holes 401 are Reserved switching fixing hole；Can be in the case that 4 fixed screws not exclusively unload during handling（Unscrew 2/1）, toward big calabash Mouth direction is released, and this mode can more efficiently dismantle replacement hard disk 7 moreover it is possible to more preferable radiate.Bottom is arranged on chassis base 4 Seat radiating aperture 402.On upper lid 1, ventilation fan mouth 101 is set.Setting display lamp lamp plate 3 in panel 2, display lamp lamp plate 3 and master Plate 6 is connected.Buckle 403 before arranging on chassis base 4, panel 2 is correspondingly arranged front bayonet slot, and chassis base 4, panel 2 lead to Cross front buckle 403, the concavo-convex clamping engagement of front bayonet slot.Buckle 404 after arranging on chassis base 4, blocks after postnotum 5 is correspondingly arranged Groove, chassis base 4, postnotum 5 are by rear buckle 404, the concavo-convex clamping engagement of rear draw-in groove.Whole machine casing all adopts in addition to panel 2 Sheet metal SGCC and SECC fingerprint-proof plate make, and improve whole machine texture and fastness；Panel 2 is adopted made of plastic, outside it Sight adopts airflow design, curve and surface blending to increased soft sense, and materials aspect adopts ABS+ fire prevention material to reach safety Fire-protection rating.Using the buckle fixed form of no screw between postnotum 5 and chassis base 4, that is, utilize panel beating itself toughness, The characteristics such as intensity, during installation, postnotum 5 directly borrows external force and pushes rear buckle 404 relevant position, it is to avoid need during installation cabinet The phenomenon such as switch different angles and lead to cabinet outward appearance to scratch, also reduce potential safety hazard simultaneously.Cabinet is integrally provided with aeration flow Road guiding radiating, such as carries radiator above the master chip of mainboard 6, improves radiating efficiency, the service life of extension device.This Utility model has structure simply, and dismounting is convenient, and product is sturdy and durable.Chassis base 4 and panel 2, postnotum 5 are all using buckle Fixed form is greatly reduced workman's installation work-hour, reduces cost, reduces potential safety hazard.
