Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments.

As shown in fig. 1 and 2, the safety rope fixer of the present embodiment includes a screw rod 1, a hanging ring 2, an expansion tube and a nut 3, both the expansion tube and the nut 3 are sleeved on the screw rod 1, and the hanging ring 2 is detachably mounted on the screw rod 1 through a detachable connection component. When the safety rope hanging device is used, the expansion pipe is inserted into the split bolt holes in the shear wall, the beam and the column, the expansion pipe is fixed in the split bolt holes by screwing the nuts 3 on the screw rods 1, and therefore the hanging ring 2 is fixed on the shear wall, the beam and the column, and the hanging ring 2 can be used as a hanging point of the safety rope. When the safety rope fixer is detached, the nut 3 is loosened, and the expansion pipe is taken out from the split bolt hole. This safety rope fixer easy dismounting can used repeatedly, does benefit to reduce cost. Because rings 2 and screw rod 1 can be dismantled and be connected, consequently conveniently change rings 2, rings 2 and screw rod 1 can make alone respectively moreover, reduce the preparation degree of difficulty, do benefit to reduce cost. The safety rope fixer also has the advantages of simple and compact structure, small size, light weight and portability.

In this embodiment, can dismantle coupling assembling includes sleeve 4, and rings 2 install on sleeve 4, and sleeve 4 cover is established on screw rod 1 and can twist soon through nut 3 and twist locking and fix on screw rod 1, and sleeve 4 is located between expansion pipe and nut 3. Sleeve 4 both convenient to operate on screw rod 1, the convenient dismantlement from screw rod 1 again, the simple operation, sleeve 4 simple structure moreover, easily preparation.

In this embodiment, rings 2 pass through connecting rod 5 to be installed on sleeve 4, and the one end and the sleeve 4 of connecting rod 5 are connected, and the other end and the rings 2 of connecting rod 5 are connected. Make rings 2 keep away from sleeve 4, rings 2 cause the hindrance to the operation when can avoiding revolving to twist nut 3.

In this embodiment, the connecting rod 5 is gradually inclined toward the nut 3 from one end to the other end. During installation, the sleeve 4 can be arranged close to a wall body, and the mechanical property of the safety rope fixer is improved. Meanwhile, the hanging ring 2 can be prevented from blocking the sleeve 4 from being arranged close to the wall.

In this embodiment, the central axis of the sleeve 4, the suspension ring 2 and the connecting rod 5 are located on the same plane. The mechanical property of the safety rope fixer is excellent.

In this embodiment, the cross section of the hanging ring 2 is circular, and the diameter of the cross section circle of the hanging ring 2 is 8mm to 12mm. The cross section of the lifting ring 2 is circular, when the lock catch of the safety rope is buckled on the lifting ring 2, the lifting ring 2 can be prevented from cutting the lock catch of the safety rope, and the lifting ring 2 and the lock catch of the safety rope can move smoothly and relatively, so that the safety is improved.

In this embodiment, the inner diameter of the hanging ring 2 is 25 mm-35 mm, and the outer diameter of the hanging ring 2 is 45 mm-55 mm. The safety rope fixer is small and exquisite, light and convenient to carry. And the lock catch of the safety rope is easily buckled on the hanging ring 2 and is easily taken down from the hanging ring 2, so that the use is convenient.

In this embodiment, the expansion pipe includes a first sleeve 6 and a second sleeve 7, the first sleeve 6 is fixedly connected to one end of the screw 1, the first sleeve 6 has a guide portion 61 for guiding the second sleeve 7 to move in a direction away from the central axis of the screw 1, and the second sleeve 7 has a guide engagement portion 71 for guiding engagement with the guide portion 61 of the first sleeve 6. The common expansion bolt is generally of a disposable structure and cannot be reused. In this structure, revolve wrong nut 3, nut 3 drives second sleeve 7 and moves to the direction that is close to first sleeve 6, and when second sleeve 7 and first sleeve 6 looks butt, the guide part 61 of first sleeve 6 can lead the outside motion of second sleeve 7, and outside inflation is fixed in the split bolt hole. When the nut 3 is loosened, the second sleeve 7 is restored to the original position, and the safety rope fixer can be taken out from the split bolt hole. The expansion can be repeatedly used, the cost is reduced, and the operation is convenient and fast.

The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, the modifications and changes obtained without departing from the technical idea of the present invention shall be considered as the protection scope of the present invention.
