The assistance handles for the computer provided by the invention can assist in unplugging and pushing; the board card can be unplugged or inserted in place by using a very low force; the handles have few components, are simple in structure and low in cost; space is saved because of horizontal installation; the handles are suitable for the chassis with limited longitudinal space.
Description
Technical field
The present invention relates to a kind of handle, more particularly, relate to the power-assisted handle that a kind of computing machine is used, and the computing machine that this handle is installed.
Background technology
Conventional computer system is changed integrated circuit board, need the user to unclamp the chassis lid lock-screw when particularly industrial computer system is changed integrated circuit board and remove chassis lid, disconnect the stube cable between interior other parts of integrated circuit board and cabinet and the peripherals, correspondingly again after the replacing connect upper cable, this process is quite consuming time and easily make mistakes.Therefore, the modular design of computer system and cabinet are outer can to plug the mainstream development trend that design has become modern computer, is widely used in the industries such as industry, military, traffic, communication.The standards such as existing CPCI, VME, ATCA, MicroTCA all are based on outside modularization and the cabinet can plug design.
The design of the outer pluggable module of cabinet makes that Computer Systems Organization is succinct and attended operation is efficient, and this design can like this, need not to pull down chassis lid when changing integrated circuit board or module from front panel plug integrated circuit board, and is fast and simple.Can be reduced to a minute level servicing time from a hour level (traditional industry computing machine), thereby shortened MTTR (mean time to repair).Present general extrapolating pulls out being connected between integrated circuit board and case back plate and mostly uses high density pin hole connector, this connector is when having high reliability and high electrical property, required contact engaging and separating force is also very large, require great effort very much with ordinary handle pull integrated circuit board, and common handle because of the point of application not in the horizontal direction, angled with integrated circuit board, the risk that causes integrated circuit board distortion and components and parts to get loose is arranged.So, need to use power-assisted handle that integrated circuit board is carried out boosting or help and pull out in when plug.
But the power-assisted handle that existing computing machine commonly used is used is as shown in Figure 1a, comprises the parts such as handle body, the metalwork that is connected with integrated circuit board, spring, rotating shaft, pressing piece, and design comparison is loaded down with trivial details, processed complex, and cost compare is high.And its installation mostly is vertical mounting design, vertical with the integrated circuit board front panel after installing, shown in Fig. 1 b, vertical with the integrated circuit board front panel after installing, vertically need larger installing space, so the longitudinal space to computer cabinet has certain requirement, and in actual the use, the longitudinal space of computer cabinet much has strict demand.
Summary of the invention
The technical problem to be solved in the present invention is, for the defects of prior art, and the power-assisted handle that provides a kind of computing machine to use, and the computing machine that uses this handle.
The technical solution adopted for the present invention to solve the technical problems is: the power-assisted handle that a kind of computing machine is used, be fixed on the computer card, comprise handle, one regulating spring and a screw, on described handle, have a fixed orifice with integrated circuit board bearing, on the described handle with computer cabinet on the column place of matching have one stressed mouthful; Described regulating spring is fixedly connected with described integrated circuit board with the described fixed orifice that described screw fit is passed handle one end; Column interlock on described stressed mouthful and the described cabinet is carried out boosting or is helped and pull out described integrated circuit board by the stress point on the column is stressed.
Preferably, described handle is a pair of, and left and right sides structural symmetry is installed in respectively the two ends of described integrated circuit board.
Preferably, described handle is horizontal installation, and is parallel with described integrated circuit board front panel after installing.
The present invention also provides a kind of computing machine that power-assisted handle is installed, and above-described power-assisted handle is installed on the described computer card.
Implement power-assisted handle of the present invention and computing machine thereof, have following beneficial effect: power-assisted handle can help and pull out and boosting, guarantee to use very little strength to make integrated circuit board extract or be inserted into the position, and stress point is parallel with integrated circuit board, can be not angled with integrated circuit board, cause integrated circuit board distortion or the components and parts equivalent risk that gets loose; The handle part is few, and is simple in structure, and cost is low; The space is saved in horizontal installation, and is parallel with the integrated circuit board front panel after installing, and is applicable to the limited cabinet of longitudinal space.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1:
Shown in Fig. 2,3,4, the power-assisted handle 10 that a kind of computing machine is used, comprise handle 101, regulating spring 102, screw 103, fixed orifice 104, stressed mouth 105, regulating spring 102 cooperates the fixed orifice 104 that passes handle 101 1 ends to be fixedly connected with integrated circuit board 11 with screw 103, stressed mouthfuls 105 with cabinet on column 12 interlocks, the stress point 121 by on the column 12 is stressed to carry out boosting or helps and pull out integrated circuit board 11.Screw 103 passes the mounting hole on regulating spring 102, fixed orifice 104 and the integrated circuit board 11, fixes on (with reference to figure 3) on the integrated circuit board 11 by nut lock.Come the installation tightness of control handle by the decrement of regulating regulating spring 102, decrement is larger, and handle is installed tightlyer, otherwise handle is installed more loosely.
