CN203894683U - Shockproof mechanism of hard disk - Google Patents

Abstract

The utility model discloses a shockproof mechanism of a hard disk. The shockproof mechanism comprises a fixed outer frame, an upper base plate, a lower base plate and an inner frame used for placing a hard disk. A spring is connected between the outer frame and the inner frame. At least two symmetrical vertical elastic pins are arranged on the side edge of the inner frame. The tail end of each of the vertical elastic pin is a spherical surface. Spherical grooves are arranged in corresponding positions on the upper and lower base plates. The vertical elastic pins are installed in the spherical grooves in a matching manner. According to the utility model, the vertical elastic pins are used for restraining the outer frame and the inner frame, thereby preventing the inner frame and the outer frame from mutual movement during slight vibration. Only during strenuous vibration will the elastic pins fall out of the spherical groove, so the spring between the outer frame and the lower frame has a vibration resisting function. The improved shockproof mechanism is simple in structure, good in use effects, and beneficial to popularization and application.

Description

Hard vibration mechanism

Technical field

The utility model relates to area of computer aided accessory technical field, is specifically related to a kind of hard vibration mechanism.

Background technology

Main frame is in moving process, and its hard disk inevitably can be given a shock, and portable hard drive or the hard disk unloading from main frame also can be because of former thereby generation vibrations such as accident drop.Hard disc of computer vibrations or drop the vibrations that reason forms and likely cause hard disk corruptions, cause loss of critical data.Have at present much for preventing the technology of hard disk vibrations, but be mostly to utilize flexible member to retrain hard disk, although can prevent that like this hard disk from significantly shaking, but flexible member has increased the small size vibration frequency of hard disk on the contrary, cause miniature vibrations all can cause hard disk to rock, be unfavorable for the normal use of hard disk, even cause data storage errors, even damage hard disk.

Utility model content

The utility model, for the problem and shortage existing about hard vibration technology in prior art, provides one can avoid small vibrations, and the hard vibration mechanism that effectively prevention significantly shakes.

Technical scheme: a kind of hard vibration mechanism, comprise fixing housing and upper and lower base plate, and for settling the inside casing of hard disk, between housing and inside casing, be connected with spring, at the individual side of inside casing, two symmetrical vertical elastic pins are at least set, the end of described vertical elastic pin is sphere, and the correspondence position on upper and lower base plate is provided with spherical groove simultaneously, and described vertical elastic pin is together with spherical groove Matching installation.In the one or both sides of described vertical elastic pin, be respectively arranged with the crossed strip seat between inside casing and housing, and be set with crossed strip on corresponding spring base.Described vertical elastic pin comprises the vertical sleeve pipe that is arranged on inside casing edge, is set with symmetrical pin at the upper/lower terminal of vertical sleeve pipe, between two symmetrical pin, is set with spring.Between described upper and lower base plate, be also connected with guide pole, guide pole two ends are provided with setting nut.

The beneficial effects of the utility model: the vertical resilient key of the utility model utilization retrains inside casing and housing, thereby motion mutually between internal and external frames while preventing from slightly shaking, only have in the time of strenuous vibration, resilient key can slide out from spherical groove, makes the spring between internal and external frames play against shock effect.The utility model is improved simple in structure effective, and result of use is good, is beneficial to very much promotion and implementation.
