Alternatively, in order that cone pulley component 110 around the shaft 100 rotate while can be produced along rotating shaft 100 it is axial
Linear displacement, in embodiment of the present utility model, cone pulley component 110 and rotating shaft 100 can be carried out using ball screw arrangement 140
Connection.For example, the part that is connected with cone pulley component 110 of rotating shaft 100 can be lead screw shaft structure, the inner side of cone pulley component 110 can be with
It is connected by ball-screw seat and lead screw shaft.
In other embodiments, it would however also be possible to employ can convert rotational motion into linear motion other machinery structure or
Electric structure makes the cone pulley component 110 can be along the linear movement of rotating shaft 100 during rotation.
Alternatively, can be connected by sliding axle 160 between wind spring bearing 120 and cone pulley component 110, by sliding axle
160 linkages for realizing wind spring bearing 120 and cone pulley component 110, and the weight of gravity balancer can be mitigated.
Alternatively, slip cap 170 can be provided with above-mentioned sliding axle 160, cone pulley component 110 can be by slip cap 170
Connection sliding axle 160, by setting slip cap 170, can reduce the friction between sliding axle 160 and cone pulley component 110, to keep away
Larger resistance is produced when exempting from cone pulley component 110 along 100 linear movement of rotating shaft.
By structure described above and operation principle, it will be appreciated by those skilled in the art that above-mentioned wind spring bearing 120
Quantity can be one or more.As shown in figure 3, in the present embodiment, in order to be further ensured that gravity balancer reliability or
The symmetry of person's structure, the quantity of above-mentioned wind spring bearing 120 can be two (such as the first wind spring bearing and the second enwinding spring axis
Hold), above-mentioned two wind spring bearing 120 can be separately positioned on the both sides of cone pulley component 110, and specifically, cone pulley component 110 can be with
The center section of rotating shaft 100 is set in, two wind spring bearings 120 can symmetrically be set in the two ends of rotating shaft 100.
Above-mentioned two wind spring bearing 120 can be connected by above-mentioned sliding axle 160, and sliding axle 160 passes through cone pulley component
110, in this way, realize the linkage of cone pulley component 110 and two wind spring bearings 120, and simple structure, it is easy to real
It is existing.
Alternatively, gravity balancer of the present utility model can also include pretension part 150, and the pretension part can be used for
Pretension is carried out to wind spring bearing, to strengthen the reliability of wind spring bearing 120.
As shown in figure 3, the pretension part can include worm screw 152 and worm gear 154, worm screw 152 can be fixed on X-ray ball
On the support of tube hanger, worm gear 154 is connected with rotating shaft 100 and is meshed with worm screw 152, in this way, can make
With preceding, by rotating shaft 100, pretightning force is applied to wind spring bearing 120 with using the resistance of worm screw 152, take less sky
Between, cost is relatively low.
It is of the present utility model another embodiment provides for a kind of X-ray bulb suspension bracket, the X-ray bulb suspension bracket can be wrapped
The gravity balancer in above-described embodiment is included, the support that is provided with the gravity balancer is additionally may included in and is connected to this
