Description

The hub shell

The utility model relates to a kind of improved fixed structure of hub shell, refers to especially a kind ofly prevent loam cake distortion and change the improved fixed structure that fixed head is installed in two ends, the box body left and right sides and convenient hub shell to the box body inside processing.

Common " fixed structure of hub shell " as Fig. 1, Fig. 2, shown in Figure 3, it comprises a hub shell 1a and a pair of fixed head 2a; This hub shell 1a comprises a box body 11a and a loam cake 12a, face is respectively equipped with a plurality of screw 111a about this box body 11a, be provided with a plurality of perforation 112a in this box body 11a front, it is in order to be provided with button and indicator light (figure slightly), be provided with a plurality of lines hole 113a in this box body 11a back,, also with respect to the screw 111a of this box body 11a and be respectively equipped with a plurality of screw 121a this loam cake 12a is locked respectively among the relative screw 121a and 111a of this loam cake 12a and this box body 11a with a plurality of element 122a that screw togather on two sides, this loam cake 12a left and right sides; This is the L type to fixed head 2a, which is provided with a plurality of perforation 21a, and this is locked respectively on the two sides, the left and right sides of this loam cake 12a with a plurality of element 22a that screw togather to fixed head 2a.Said structure has many shortcomings, must to fixed head 2a whole hub shell 1a be pulled out by spurring this when for example using, yet used of a specified duration and found that this is out of shape the two sides, the left and right sides of this loam cake 12a and this box body 11a to the normal constantly pulling of fixed head 2a, and this box body 11a itself is because inner rear is connected to circuit and device, thereby must bear very great torsion, and fixed head 2a is located on the loam cake 12a, when box body 11a because of heavy when sunk in the rear, open torsional deformation outside the two sides, the loam cake 12a left and right sides and become a plane, box body 11a serious distortion distortion especially simultaneously, this haves much room for improvement.

The purpose of this utility model provides a kind of hub shell, it is installed in two ends, the box body left and right sides with fixed head, one can directly prevent the distortion of loam cake and box body to the heavier box body application of force when fixed head spurs, and still can will not raise by two elbows conveniently to the box body inside processing.

For achieving the above object, the utility model is taked following design: this hub shell comprises at least one hub shell, and this long-pending rack enclosure comprises a box body and a loam cake, and this loam cake locking is on this box body; A pair of fixed head be installed in respectively this box body about on the face.Because fixed head is installed in two ends, the box body left and right sides, therefore, when the pulling fixed head, be direct to the heavier box body application of force, can prevent the distortion of loam cake and box body.

In the utility model, the box body of described hub shell is a rectangle, forms respectively on two sides, the left and right sides Shape, and be provided with a plurality of screws thereon, and about the front end of face be respectively equipped with fixed part, be provided with a plurality of perforation in this box body front, these a plurality of perforation are that a pore and a gross porosity upper and lower settings are become one group, and should organize spaced set from left to right and formed two row perforation, be provided with the neat perforation of number row from left to right, be provided with a plurality of lines hole in this box body back, this a plurality of lines hole is that a gross porosity and two pore upper and lower settings are become one group, and should organize spaced set from left to right and form two winding displacement holes.

In the utility model, the loam cake of described shell is rectangle, and also forms respectively with respect to this box body on this two sides, loam cake left and right sides

Shape is on it and be provided with a plurality of screws.

In the utility model, this is the L type to fixed head, which is provided with a plurality of perforation, and this is screwed in each perforation on it and the screw on two fixed parts of this box body to fixed head with a plurality of elements that screw togather, and this fixed head and this box body are locked together mutually.

In the utility model, described each hub shell is arranged in the hub combination sideboard.During operation, can by about two fixed heads pull out or push.

The utility model is described in further detail below in conjunction with accompanying drawing.

To shown in Figure 6, the utility model is to provide a kind of hub shell improved fixed structure as Fig. 4, and it comprises at least one hub shell 1 and a pair of fixed head 2; This hub shell 1 comprises a box body 11 and a loam cake 12, and this box body 11 is rectangle, and forms respectively on two sides, the box body left and right sides

Shape is one section low limit by one section flash by one section hypotenuse transition promptly.Locate between flash and the hypotenuse to be real face, be used for fixing fixed head 2.Form breach between low limit and hypotenuse, be convenient to the operator and operate from indentation, there.And in position be provided with a plurality of screws 111, and make in about the front end of face be that high face place is provided with fixed part 114 respectively, these box body 11 fronts are provided with a plurality of perforation 112, these a plurality of perforation 112 are that a pore and a gross porosity upper and lower settings are become one group, and should organize spaced set from left to right and formed two row perforation 112, be provided with the neat perforation 112 of number row from left to right, be provided with a plurality of lines hole 113 in these box body 11 back, this a plurality of lines hole 113 is that a gross porosity and two pore upper and lower settings are become one group, and should organize spaced set from left to right and formed two winding displacement holes 113, this loam cake 12 is rectangle, and also forms with respect to this box body 11 in this two sides, loam cake 12 left and right sides Shape is one section low limit by one section flash by one section hypotenuse transition promptly.Form breach between flash and hypotenuse, be convenient to exposed fixed head 2.Locate to be real face between low limit and the hypotenuse, be used to hide the breach on the two sides, the left and right sides of box body 11.On it and be provided with a plurality of screws 121, a plurality of elements 122 that screw togather of these loam cake 12 usefulness are aimed at

screws

121 and 111 and screwed in, this box body 11 is locked mutually with this loam cake 12.

This is the L type to fixed head 2, which is provided with a plurality of perforation 22, and this is screwed in screw 111 on two fixed parts 114 of these perforation 22 and this box body 11 to a plurality of elements 21 of screwing togather of fixed head 2 usefulness, and this fixed head 2 and this box body 11 are locked together mutually.

As shown in Figure 7, it is the utility model embodiment one, as operator during to these box body 11 inside processings, can not will two elbows 4 raise.

As shown in Figure 8, it is the utility model embodiment two, for the ease of the operation, several hub shells 1 can be arranged in the hub combination sideboard 5, during operation can by about two fixed heads 2 pull out or push.

The utility model has the advantages that:

1, fixed head is installed in two ends, the box body left and right sides, can be directly to the heavier box body application of force when fixed head spurs, and prevent that loam cake and box body from pullling distortion mutually.

2, still can will not raise by two elbows conveniently to the box body inside processing.

3, too heavy and when sinking, also needn't worry loam cake to open into the plane outward when box body weight, can make to screw togather element and still closely lock and do not come off.

Comprehensively above-mentioned, the utility model is the improved fixed structure of rare hub shell.

The above only is the preferable possible embodiments of the utility model, and non-so promptly inflexible limit the utility model claim so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner all is included in the utility model scope.
