Abstract
A lifting bar double-safety device comprises a lifting wheel, a lifting bar and a hanging rod, wherein the lifting wheel is installed on a roof lifting hook, a hole in the lifting bar is fixed with the lifting wheel through a round-head bolt, a hole in the lifting bar is fixed with the upper end of the hanging rod through a bolt, and a steel wire rope is further arranged between the lifting wheel and the hanging rod. One end of the steel wire rope is fixed on one side of the upper end of the suspender after bypassing the hanging wheel, the lifting bar and the roof lifting hook, and the other end of the steel wire rope is fixed on the other side of the upper end of the suspender. The utility model discloses a set up a wire rope between hanging wheel and jib, this wire rope walks around hanging wheel, roof lifting hook and lifting tab back, fixes the both ends of wire rope in the both sides of jib upper end respectively to avoid causing the danger that the ceiling fan dropped when the lifting tab or the bolt of connecting the lifting tab take place to become invalid. The novel bolt has the characteristics of simple structure and convenience in installation, and the bolt and the steel wire rope are double-insurance so that the novel bolt is safer and more reliable to use.
Description
Technical field
The utility model relates to a kind of joint hinge dual fail-safe device of ceiling fan.
Background technique
Present ceiling fan class suspension clamp on the market is connected with suspension rod, reaches joint hinge and roof suspension hook directly by hanging installation, and when taking place to lose efficacy for any one, ceiling fan all can fall, and causes certain danger.Chinese patent document number CN201358962 discloses a kind of large-scale ceiling fan safty device on December 9th, 2009, and it mainly comprises safety hook.Power plant are contained on the fixing frame, and rotating disk is connected with power plant, and safety hook is connected a little higher than fixing frame boss of safety hook crotch part through screw with rotating disk.It is said that when fan rotating disk and power plant disconnection, safety hook crotch part can also catch on the fixing frame boss, and fan is not fallen down.But this device can only solve the hidden danger that ceiling fan rotating disk and power plant come off.Therefore, be necessary to do further improvement.
The model utility content
The purpose of the utility model aims to provide a kind of simple in structure, easy for installation, safe and reliable joint hinge dual fail-safe device, to overcome deficiency of the prior art.
A kind of joint hinge dual fail-safe device by this purpose design; Comprise hanging wheel, joint hinge, suspension rod; Hanging wheel is installed on the suspension hook of roof; Hole and hanging wheel are fixed through snap bolt on the joint hinge, and hole and suspension rod upper end is through bolt under the joint hinge, and its structure characteristic is also to be provided with steel cable between hanging wheel and the suspension rod.
Said wire rope one end is walked around a side that is fixed on the suspension rod upper end behind hanging wheel, joint hinge and the roof suspension hook, and the other end of wire rope is fixed on the opposite side of suspension rod upper end.
Said joint hinge is the bending sheet, last hole and following hole vertical array, and joint hinge is arranged in pairs in the suspension rod upper end.
The two ends port of said wire rope is provided with annulus, is separately fixed at through screw on the both sides of suspension rod upper end.
The utility model is through being provided with steel cable between hanging wheel and suspension rod; After this wire rope is walked around hanging wheel, roof suspension hook and joint hinge; Be separately fixed at the both sides of suspension rod upper end to the two ends of wire rope, with the danger of avoiding when inefficacy takes place for joint hinge or the bolt that connects joint hinge, causing ceiling fan to drop.It has characteristics simple in structure, easy for installation, and bolt and the use of wire rope double insurance are more safe and reliable.
Description of drawings
Fig. 1 is the utility model one embodiment's a decomposition texture schematic representation.
Fig. 2 is the structural representation after assembling.
Among the figure: 1 is hanging wheel, and 2 is joint hinge, and 3 is suspension rod, and 4 is wire rope, and 4.1 is annulus, and 5 is snap bolt, and 6 is bolt, and 7 is screw.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 2, a kind of joint hinge dual fail-safe device comprises hanging wheel 1, joint hinge 2, suspension rod 3, and hanging wheel 1 is installed on the suspension hook of roof, and joint hinge 2 is the bending sheet, last hole and following hole vertical array, and joint hinge 2 is arranged in pairs in suspension rod 3 upper ends.Hole and hanging wheel 1 are fixing through snap bolt 5 on the joint hinge 2, and hanging wheel 1 can freely be rolled, and conveniently the suspension hook extension is got from the roof, and 2 times holes of joint hinge and suspension rod 3 upper ends are fixing through bolt 6, also are provided with steel cable 4 between hanging wheel 1 and the suspension rod 3.Wire rope 4 one ends are walked around a side that is fixed on suspension rod 3 upper ends behind hanging wheel 1, joint hinge 2 and the roof suspension hook, and the other end of wire rope 4 is fixed on the opposite side of suspension rod 3 upper ends.Joint hinge 2 is the bending sheet, last hole and following hole vertical array, and joint hinge 2 is arranged in pairs in suspension rod 3 upper ends.The two ends port of wire rope 4 is provided with annulus 4.1, is separately fixed at through screw 7 on the both sides of suspension rod 3 upper ends.
The both sides of suspension rod 3 upper ends are fixing by the wire rope on roof suspension hook, hanging wheel 14, and when the bolt of joint hinge 2 or connection joint hinge 2 took place to lose efficacy, ceiling fan can not fall down yet.
In the present embodiment, fixed block has the cooperation of snap bolt, packing ring, cotter pin, the cooperation of the cooperation of bolt, packing ring, spring washer, nut, cotter pin and screw, packing ring.
