For solving the problems of the technologies described above, the utility model is by technical scheme as described below: a kind of magnetic head erecting frame, it includes one by edge on, one left edge, the centre that one lower frame and a right edge surround is formed with the frame body of a magnetic head installation position, described left edge and/or right edge are the shape structure of crawling, the place stretches out and is formed with a left connecting portion in the middle of the outside of described left edge, the place, outer end of described left connecting portion is formed with a left installing plate, the place stretches out and is formed with a right connecting portion in the middle of the outside of described right edge, and the place, outer end of described right connecting portion is formed with a right installing plate.
In the said head erecting frame, it is tabular that described left connecting portion and right connecting portion are vertical bar.
In the said head erecting frame, be formed with a left mounting hole on the described left installing plate, and be formed with a right mounting hole on the described right installing plate.
In the said head erecting frame, the structure of described left edge and right edge is identical.
In the said head erecting frame, described left edge include a last line part that is connected with the described left end of going up edge, from described first bend of going up the outside protrusion that line part extends, from cathetus portion that described first bend extends, second bend and the following line part that is connected with the left end of described lower frame from described second bend extension from the outside protrusion of described cathetus portion extension.
In the said head erecting frame, described right edge include a last line part that is connected with the described right-hand member of going up edge, from described first bend of going up the outside protrusion that line part extends, from cathetus portion that described first bend extends, second bend and the following line part that is connected with the right-hand member of described lower frame from described second bend extension from the outside protrusion of described cathetus portion extension.
In the said head erecting frame, it is tabular that the last edge of described frame body and lower frame are vertical bar.
Useful technique effect of the present utility model is: the left edge and/or the right edge of the frame body of this magnetic head erecting frame are designed to the structure of crawling, the stress that is produced when making magnetic head work can be dispersed on left edge and/or the right edge, and can not concentrate the corner that acts on frame body, can avoid the corner of frame body to damage, thereby prolong the serviceable life of this magnetic head erecting frame because of stressed excessively doing sth. in advance.

Embodiment
For making those of ordinary skill in the art be expressly understood the purpose of this utility model, technical scheme and useful technique effect more, the utility model is further elaborated below in conjunction with drawings and Examples.
Referring to figs. 2 and 3 shown in, magnetic head erecting frame disclosed in the utility model includes a frame body 10, this frame body 10 include connect in turn and surround one one on edge 100, one left edge 101, one lower frame 102 and a right edge 103, its centre is formed with a magnetic head installation position 12, on this magnetic head installation position 12, lower edge is extended respectively and is formed with a upper mounted plate 14 that is approximately perpendicular to this frame body 10 separately, bottom plate 16, by on this, bottom plate 14,16 and magnetic head is fixed among this magnetic head installation position 12, thus realize the assembling of magnetic head and magnetic head erecting frame.
As shown in drawings, the last edge 100 and the lower frame 102 of this frame body 10 all are designed to the vertical bar platy structure, and left edge 101 and right edge 103 then all are designed to the shape structure of crawling.The place stretches out and is formed with the tabular left connecting portion 18 of bar always in the middle of the outside of this left side edge 101, and the place stretches out and is formed with the tabular right connecting portion 20 of bar always in the middle of the outside of this right side edge 103, place, the outer end of this left side connecting portion 18 is formed with a left installing plate 22 that has left mounting hole 220 on it, and be formed with a right installing plate 24 that has right mounting hole 240 on it at place, the outer end of this right side connecting portion 20, by fixedlying connected of this left and right installing plate 22,24 and target device, this magnetic head erecting frame (and magnetic head) can be installed on target location.
Magnetic head erecting frame disclosed in the utility model, the left and right edge 101,103 of its frame body 10 is designed to the structure of crawling, the stress that is produced when making magnetic head work can be dispersed on left edge 101 and the right edge 103, and can not concentrate the corner that acts on this frame body 10, can avoid the corner of this frame body 10 to damage, thereby prolong the serviceable life of this magnetic head erecting frame because of stressed excessively doing sth. in advance.At acting force is that 110g, deflection are under the experiment condition of 0.8mm, is respectively the serviceable life of five specimen 1,380,000 times, 1,450,000 times, 1,320,000 times, 1,350,000 times and 1,520,000 times.
In the embodiment shown in the figures, left side edge 101 is identical with the structure of right edge 103, and it includes a last line part that is connected with last edge 100 104, from first bend 105 that should go up outside protrusion that line part 104 extends, a cathetus portion 106 from these first bend, 105 extensions, second bend 107 and the following line part 108 that is connected with lower frame 102 from these second bend, 107 extensions from the outside protrusion of these cathetus portion 106 extensions.But be appreciated that ground, this left side edge 101 and right edge 103 are not limited to above-mentioned structure, also can be the structures of crawling of other shapes, and left edge 101 also is not limited to both with right edge 103 and is identical structure, also can be designed to both and be different structure.
The above only is a preferred embodiment of the present utility model, but not the utility model is done any pro forma restriction.Those skilled in the art can impose various changes that are equal to and improvement on the basis of the foregoing description, all equivalent variations or modifications of being done in the claim scope all should fall within the utility model protection domain.
