The specific embodiment
With reference to Fig. 1-Fig. 5, the pulley 102 that this holder device 100 mainly comprises installing rack 101 and is connected the installing rack bottom.Installing rack 101 comprises superposed lamp installation plate 103 and the pulley installing plate 104 that is positioned at the bottom.The quantity of its middle pulley installing plate 104 is two groups, and two every group.These two pulley installing plates 104 are oppositely arranged, and pulley 102 is installed between these two pulley installing plates 104 by rotating shaft 105.Its shaft 105 is cylindrical, and two ends of rotating shaft 105 are to cut the shape that described cylinder obtains along the axis direction that is parallel to rotating shaft 105, and this end comprises one or several arc surfaces, and arc surface is provided with screw thread.Just, the end cross-sectional of rotating shaft 105 is not circular.The two ends of the rotating shaft 105 shown in Fig. 4 are cylinder both sides shapes through cutting, and the quantity of arc surface is two sections.
On one of them of two pulley installing plates 104, be provided with for 105 groups of first breach 106 of going into of rotating shaft, another is provided with the hole of inserting for rotating shaft 105, and in the end patchhole of rotating shaft 105, the other end snaps in from first breach 106.Certainly, also first breach 106 can be set all on two pulley installing plates 104.
This first breach 106 is 90 ° the T shape that turns clockwise, and comprises group inlet 107 and positioning port 108.Group inlet 107 is positioned at the middle part or the top of positioning port 108, and its bore is less than the height of positioning port 108.The bottom shape of positioning port 108 is identical with the shape of rotating shaft 105, when rotating shaft 105 places the bottom of positioning port 108, can not rotate.After pulley 102 is set in the rotating shaft 105, be inserted in pad 109 respectively at the two ends of rotating shaft 105.Afterwards, with the two ends of rotating shaft 105 respectively from the pulley installing plate 104 corresponding hole, group inlet 107 enter, and be positioned the bottom of positioning port 108; If first breach 106 all is set on two pulley installing plates 104, then with the two ends of rotating shaft 105 respectively from the pulley installing plate 104 corresponding group of inlet 107 enter, and be positioned the bottom of positioning port 108.At this moment, pad 109 is between pulley installing plate 104 and pulley 102, and 105 rotations around the shaft.
In the end of rotating shaft 105, also be arranged with anticreep pad 110.This anticreep pad 110 is buckled on the outside of pulley installing plate 104, and it is provided with the hole 111 identical with the end shape of rotating shaft 105.At the top of anticreep pad 110, the outstanding holding section 112 that is provided with.This holding section 112 is perpendicular to the main body of anticreep pad 110, extends towards pulley installing plate 104, inserts positioning port 108 and offsets with the roof of positioning port 108.The width of holding section 110 is identical with the width at positioning port 108 tops.Such structure makes anticreep pad 110 not move with respect to pulley installing plate 104.Hole on the anticreep pad 110 is identical with the end cross-sectional shape of rotating shaft 105, and can be closely chimeric.Because the effect of holding section 112 on the anticreep pad 110, and hole 111 is arranged on the middle part, and closely chimeric with rotating shaft 105, therefore, can prevent to withdraw from the group inlet 107 of rotating shaft 105 from pulley installing plate 104.
Need to prove that the anticreep pad also can be other shape, for example circular, L shaped, C shape etc., hole 111 can be substituted by second breach, and the end of this second breach and rotating shaft 105 is closely chimeric.Therefore, when the opening direction of the opening direction of this second breach and first breach 106 on the pulley installing plate 104 not simultaneously, can prevent that rotating shaft 105 from deviating from, preferably, this second breach is opposite with the opening direction of first breach 106.When the opening direction of first breach 106 and second breach was identical, the opening size of second breach was less and closely chimeric with the end of rotating shaft 105, is not enough to allow rotating shaft 105 deviate from equally, can reach same purpose.
In the outside of anticreep pad 110, also be provided with securing member, in this embodiment, securing member is a locknut 113.The arc surface of the end of rotating shaft 105 is provided with screw thread, and the screw thread in locknut 113 and the rotating shaft 105 screws, thereby makes the axial restraint of anticreep pad 110 along rotating shaft 105.To cooperate more closely reliably in order making, between anticreep pad 110 and locknut 113, to be provided with elastic washer 114.This elastic washer 114 can be made by for example rubber.
