The specific embodiment

Below by most preferred embodiment and accompanying drawing the hub shell body that is used to install the Straight pull spoke of the present utility model is elaborated.

As Fig. 3, Fig. 4 and shown in Figure 5, the utility model is used to install hub shell body 20 preferred embodiments of Straight pull spoke, be to be connected to a wheel rim 200 for most spoke 100 drawings, aforementioned spoke 100 respectively has one and is attached at block head 110 and on this hub shell body 20 and is fixed on this block head 110 and can be fixed on shaft 120 on this wheel rim 200.And this hub shell body 20 is to be rotatably to be supported on wholeheartedly on the axle unit 10.

This axle unit 10 has an axostylus axostyle 11 and the most individual bearing 12 that is located on this axostylus axostyle 11 of organizing along axis L extension.

This housing 20 has one and centers on perisporium 21 and the most individual spoke mount pad 22 that is located at these perisporium 21 opposite two ends that encircles that this axis L is produced.In the present embodiment, these perisporium 21 2 ends respectively are provided with 4 spoke mount pads 22.

The outside wall surface 212 that the end face 211 and that this perisporium 21 has two opposing settings is produced between aforementioned end face 211 and around this axis L.

Aforementioned spoke mount pad 22 is to be protruded outwardly by this outside wall surface 212, and respectively has an end face 221 corresponding to this outside wall surface 212, a pair of should end face 211 and be engaged on first side 222 between these end face 221 1 lateral borders and this outside wall surface 212, one with second side 223 of these first side, 222 opposing settings and be engaged on this first, two side faces 222, between 223 and be one first of opposing setting mutually, two link surfaces 224,225, one first shrinkage pool 226 that is arranged with and is provided with vertically by this first side 222, one is provided with and is through to by this first shrinkage pool 226 first short slot 227 of end face 221 vertically, one along first translot 228 that is arranged circumferentially and is through to by this first shrinkage pool 226 and first short slot 227 first link surface 224, one second shrinkage pool 236 that is arranged with and is provided with vertically by this second side 223, one is provided with and is through to by this second shrinkage pool 236 second short slot 237 of end face 221 vertically, one along be arranged circumferentially and by second translot 238 and that this second shrinkage pool 236 and second short slot 237 are through to second link surface 225 separate this first, two translots 228, partition wall 24 between 238.Aforementioned first and second shrinkage pool the 226, the 236th, vertically relatively and interpenetrate and run through partition wall 24, aforementioned first and second translot the 228, the 238th is opposite setting along hoop, and be to be diagonally extending along hoop, the width of first and second translot 228,238 correspondences self axis is wide less than the footpath of block head 110, and the width of first and second short slot 227,237 corresponding hoops is less than the width of first and second shrinkage pool 226,236 corresponding hoops.And utilize the setting of partition wall 24, can make self axis of first and second translot 228,238 is to be set in distance.

Fig. 5 for another example, Figure 6 and Figure 7, when desire is installed spoke 100, be to make the block head 110 of each spoke 100 one by one in alignment with first of institute's desire installation, two shrinkage pools 226,236,120 of shafts are in alignment with pairing first, two short slots 227,237, and spoke 100 is inserted in vertically, when shaft 120 touches partition wall 24, again spoke 100 is pivoted along hoop, shaft 120 just can be set in first, two translots 228, in 238, and utilize first, two translots 228, the width of 238 correspondences self axis is less than the wide effect in the footpath of block head 110,110 on block head is that inlay card is spacing first pivotly, two shrinkage pools 226, in 236, and be attached on the spoke mount pad 22, the shaft 120 of spoke 100 is from first, two translots 228,238 stretch out and with wheel rim 200 interlocking (see figure 3)s.

Therefore, effect of the present utility model can be summarized as follows:

One, utilizes the setting of the partition wall 24 of spoke mount pad 22, make that first and second translot 228,238 self axis is to be set in distance, then when the shaft 120 of spoke 100 from first and second translot 228,238 stretch out and with wheel rim 200 interlockings, and when carrying out staggered form braiding spoke 100, though the shaft 120 of spoke 100 can be intersected with each other, but do not have because of overlapping extruding and make that shaft 120 is diastrophic possible, so can avoid producing the stress concentration phenomenon, can prolong the service life of spoke 100.

Two, when assembling spoke 100, be directly the block head 110 of spoke 100 to be aimed at first and second shrinkage pool 226,236, and shaft 120 is in alignment with pairing first and second short slot 227,237, make spoke 100 be inserted in vertically, pivot again along hoop, and shaft 120 is set in first and second translot 228,238, just can make that spoke 100 is attached on the spoke mount pad 22, so operational motion is simple, assembling speed is fast.

Three, first and second shrinkage pool the 226, the 236th, vertically relatively and interpenetrate, and first and second translot 228,238 also be according to desire with the position of these wheel rim 200 interlockings and make according to default machining angle skewed, all quite easy on making.

What deserves to be mentioned is, hub shell body of the present utility model also can be only therein an end spoke mount pad 22 is set, the other end then adopts other pattern to install for spoke.
