Problem to be solved in the utility model provides a kind of simple in structure, safe and reliable, dihedral fixator that cost is low.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of dihedral fixator comprises two fixed mounts and two regulating arms; Described two fixed mounts all are fixed on the equipment of affixed bearing block, and two fixed mounts are positioned at the bearing block both sides; All hinged by a connecting axle between described regulating arm and the fixed mount, between two regulating arms; The radial direction of described connecting axle is provided with a screw, and described screw coupling connects one and regulates leading screw, and an end of described adjusting leading screw connects a wrap, and described wrap is sleeved on to be treated on the fixture.

Further, the front end of described fixed mount is provided with a U-shaped body, and two side arms of described U-shaped body are provided with through hole, and described through hole and connecting axle are connected.

Further, described regulating arm is the long column shape structure, and the two ends of regulating arm respectively are provided with an adjusting bracket, and described adjusting bracket is provided with a U-shaped body, and two side arms of described U-shaped body are provided with through hole, and described through hole and connecting axle are connected.

Further, described regulating arm is hollow-core construction, and the center of regulating arm both ends of the surface is provided with the screw of different rotation directions; U-shaped body on the described adjusting bracket oppositely be provided with a screw rod; The screw rod of described adjusting bracket and the screw on the regulating arm are connected.

Further, described adjusting leading screw and wrap link together by a lock rope socket.

Further, described wrap is flexible wrap.

Advantage and the good effect that the utlity model has are: adopt the technical program for dismounting bearing block, replacing or safeguard that bearing saved the space, and increased path increment, broken away from the dependence to the large-scale lifting device in scene, also saved the loaded down with trivial details work of temporary erection simple and easy hoisting instrument at the scene, human resources have been saved, and reduced potential safety hazard, and had advantage of simple structure.

The specific embodiment

Enumerating a specific embodiment below in conjunction with accompanying drawing is further elaborated the utility model.

As shown in Figure 1, present embodiment is a kind of dihedral fixator, comprises two fixed mounts 2 and two regulating arms 5; Two fixed mounts all are fixed on the equipment of affixed bearing block 11, and two fixed mounts 2 are positioned at bearing block 11 both sides; All hinged by a connecting axle 3 between regulating arm 5 and the fixed mount 2, between two regulating arms 5; The radial direction of connecting axle 3 is provided with a screw, and the screw coupling connects one and regulates leading screw 7, and an end of regulating leading screw 7 connects a wrap, and wrap is sleeved on to be treated on the fixture.

As shown in Figure 1, in the present embodiment, the equipment of rigid bearing is frame 1, and wrap is flexible wrap, select hanging belt 9 for use, and hanging belt is sleeved on the drum shaft 10; An end of regulating leading screw 7 is connected with hanging belt 9 by a lock rope socket 8, and the other end of regulating leading screw is provided with an operating handle or handwheel 6.

As Fig. 2, shown in Figure 3, in the present embodiment, the front end of fixed mount 2 is provided with a U-shaped body 21, and two side arms of U-shaped body 21 are provided with through hole, and through hole and connecting axle 3 are connected;

As shown in Figure 4, the regulating arm 5 in the present embodiment is vast sky stem shape structure, and the center of regulating arm 5 both ends of the surface is provided with the screw 51 of different rotation directions; The two ends of regulating arm 5 respectively are provided with an adjusting bracket 4, and as Fig. 5, shown in Figure 6, adjusting bracket 4 is provided with a U-shaped body 41 and a screw rod 42, and two side arms of U-shaped body 41 are provided with through hole, and through hole and connecting axle are connected; The screw rod 42 of adjusting bracket 4 is connected with the screw 51 on the regulating arm 5.

In the present embodiment, regulating arm 5 be provided with an installing hole that is used for mounting knob in the radial direction, be convenient to adjust the length of regulating arm 5.

In the present embodiment, analyze from vertical direction, the monolateral weight of drum shaft just through hanging belt 9, lock rope socket 8, regulate parts such as leading screw 7 and passed on the connecting axle 3 of the top, this moment, drum shaft 10 still can be realized the purpose of fixing with regard to having reached the fastening bolt that unclamps on the bearing block 11.

Analyze from horizontal direction, can realize partial dislocation thereby change connecting axle 3 by rotation hand wheel in the horizontal direction at the occlusal position cylinder of regulating on the leading screw 7.Because two fixed mounts 2, adjusting bracket 4, regulating arms 5 pass through the connection of three connecting axles 3, formed a leg-of-mutton structure, two fixed mounts 2 are fixing with frame 1, the thread rotary orientation at two tubulose regulating arm 5 two ends is different again, therefore by rotation tubulose regulating arm 5, just but length adjustment is carried out on one side of diabolo, if rotating tubulose regulating arm 5 simultaneously increases leg-of-mutton both sides respectively, also can realize drum shaft displacement in the horizontal direction.Hence one can see that, and present embodiment has increased the path increment of bearing or bearing block, and dismounting and adjusting are more convenient, have saved working space simultaneously.

In sum, by this device, drum shaft 10 both can remain on the frame, also simultaneously for dismounting bearing block, replacing or safeguard that bearing saved the space, broken away from the dependence to the on-site hoisting instrument, also saved the loaded down with trivial details work of temporary erection simple and easy hoisting instrument at the scene, saved human resources, and reduced potential safety hazard.

More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
