Abstract
The utility model discloses a hard disk bracket for a set-top box (STB); the hard disk bracket comprises a bracket body which has an installation hole for screw fastening. The hard disk bracket is characterized in that the circumference of the installation hole is also opened with an opening groove communicated with the installation hole, the opening groove is used for clamping an external shockproof gasket in the installation hole. The edge toward the screwing direction of a bolt has a smoothing chamfer. According to the utility model, an opening groove is around the installation hole, the shockproof gasket can be clamped in the installation hole through the opening groove, the assembling operations are simple and damage to the gasket can be avoided. The edge of the opening groove is provided with a smoothing chamfer for preventing the damage of the shockproof gasket because of the friction between the shockproof gasket and the aculeated edge of the opening groove by the action of the bolt torque.
Description
Technical field
The utility model relates to a kind of TV set-top box, specifically relates to a kind of set-top box hard disk bracket.
Background technology
Traditional TV set-top box generally can be divided into analog set top and top box of digital machine, and analog set top is mainly used to receive encrypts simulating signal, and top box of digital machine can be used to receive satellite television or Digital Television.Along with the development of Ethernet, data communication facility that the IPTV set-top box is integrated can playing network television, and this class IPTV set-top box is provided with ethernet interface circuit, can insert IP network, realizes program request, interaction function and various value-added service function.
In order to realize recording of video frequency program, proposed a kind of set-top box, thereby increased the function of set-top box greatly with hard disk.Generally hard disk is fixed on the hard disk mounting bracket, again with the hard disk mounting bracket by screw lock on the set-top box box body.For shockproof, need between mounting bracket and box body, earthquake washer be set, as shown in Figure 1, earthquake washer 04 fixes in the mounting hole of hard disk mounting bracket 1, make earthquake washer 04 bear hard disk bracket 1 and on the weight of hard disk.Pass the central through hole of earthquake washer 04 again with screw 03, be connected with set-top box base 02 thereby tighten screw 03.This structure exists a defective to be, earthquake washer 04 snaps in the mounting hole of support relatively trouble, need with earthquake washer 04 extremely extruding just can put into mounting hole, inconvenience during assembling.
Summary of the invention
The technical problems to be solved in the utility model remedies above defective exactly, proposes a kind of set-top box hard disk bracket, and is easy to assembly easy, and can alleviate the friction infringement to earthquake washer.
Technical matters of the present utility model is solved by the following technical programs.
This set-top box hard disk bracket comprises rack body, offers on the rack body to be used for the mounting hole that screw connects.
The characteristics of this set-top box hard disk bracket are: the circumference place of described mounting hole also offers the open slot that is communicated with mounting hole, and described open slot is used for extraneous earthquake washer is snapped in the mounting hole.
The edge towards the screw-driving direction of described open slot has level and smooth chamfering.
The bottom margin of rack body is extended with installation foot, and described mounting hole and open slot are opened on the installation foot.
Described installation foot comprises horizontal installation foot and vertical installation foot.
The open slot of offering on described horizontal installation foot and the vertical installation foot is respectively towards orthogonal direction.
The utility model is compared with the prior art has following beneficial effect: be provided with open slot, earthquake washer can stick in the mounting hole by open slot, and assembly manipulation is simple, need not too much to push earthquake washer, thereby avoids damaging packing ring.The edge of open slot is provided with level and smooth chamfering towards the screw threads veer, thereby avoids earthquake washer to be scratched with the friction of open slot sharp edges under the effect of screw torsion.Mounting hole and open slot are opened on the installation foot, and the opening direction of open slot is vertical mutually, avoids earthquake washer to skid off from mounting hole.
Description of drawings
Fig. 1 is the mounting structure figure of hard disk mounting bracket and set-top box box body;
Fig. 2 is the structural drawing of the utility model embodiment;
Fig. 3 is the partial enlarged drawing among Fig. 2.
Embodiment
A kind of set-top box hard disk bracket as shown in Figures 2 and 3, the edge of rack body 1 is extended with four installation feet 2, wherein two installation feet are horizontal installation foot, be positioned at the left side edge of Fig. 2 medium-height trestle body 1, two installation feet are vertical installation foot in addition, lay respectively at the upper and lower both sides of the edge of rack body 1.Offer mounting hole 3 on each installation foot 2, attachment screw passes mounting hole 3 rack body is connected with the set-top box base during assembling.The circumferential edges of mounting hole 3 offers open slot 4, and earthquake washer can snap in the mounting hole 3 from open slot 4 during assembling.
With reference to shown in Figure 1, assembling process is simultaneously: earthquake washer 04 extruding is sticked in the mounting hole of rack body 1 from open slot 4, and rack body 1 and hard disk fixed thereon will be supported on the earthquake washer 04 like this.The bottom of rack body 1 by earthquake washer 04 is placed on the Bottom of box body 02.Pass earthquake washer 04 with screw 03 and cooperate fixingly with threaded hole on the Bottom of box body 02, tighten screw 03 and compress earthquake washer 04.
In order to prevent damage earthquake washer when earthquake washer 04 extruding is sticked into open slot 4, the edge of open slot 4 is provided with opening chamfering 6.Thereby for prevent in the process of tightening screw 03 earthquake washer 04 under the effect of torsion with edge extruding, the friction damage earthquake washer of open slot 4, edge at open slot 4, towards screw 03 tightening direction direction shown in arrow among Fig. 3, be provided with level and smooth chamfering 5, the chamfer radius of level and smooth chamfering 5 is bigger, the surface continuously smooth can prevent from earthquake washer is caused extruding.Earthquake washer 04 skids off the opening direction difference of each open slot 4 on installation foot 2 from open slot 4 when preventing work.Horizontal opening direction horizontal X direction in Fig. 2 of the open slot 4 on the installation foot, the vertical opening direction of the open slot 4 on installation foot Y direction longitudinally in Fig. 2, thus prevent that earthquake washer 04 from skidding off easily from open slot 4.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
