The device of the invention is reasonable in design, simple in structure and easy in operation, and well solves the problems of complicated and difficult operation of the tool U-shaped ring in the existing helical nail-piercing mode and easy increase of working intensity of operators.

Description

Portable Tool U-ring

technical field

The invention relates to the technical field of special tools for power transmission lines, in particular to a portable tool U-shaped ring.

Background technique

The tool U-ring is a metal connection standard part. It is often used to connect the angle steel of the tower and the lifting object in the work. It bears the weight of the lifting object and the shear force of the angle steel on the inner side of the U-shaped ring. The existing U-shaped ring piercing nails are in a spiral shape. This form is firmly connected and not easy to disengage, but the operation is complicated, which increases the work intensity of the tower operators and is not conducive to the operation during work. The tool U-shaped ring of this style The transformation was appealed by the front-line production staff.

Contents of the invention

The object of the present invention is to provide a portable tool U-ring in order to solve the problem that the existing tool U-ring in the helical nail-piercing mode is complicated and difficult to operate and easily increases the working intensity of the operator.

The present invention is achieved through the following technical solutions:

A portable tool U-shaped ring, including a U-shaped ring body and a bolt, the bolt is inserted into the ring openings at both ends of the U-shaped ring body, and the parts of the bolt located in the two ring openings of the U-shaped ring body are respectively provided with clips. The ring groove (the ring groove is a ring groove opened around the bolt), the groove wall on the outer side of the ring groove is a vertical straight surface, and the groove wall on the inner side is a gentle slope (closer to the One side of the end of the pin is the outer side, and the side close to the middle of the pin is the inner side); the bottom of one of the ring openings of the U-shaped ring body is provided with a ballistic hole that communicates with the through hole of the ring mouth, and the ballistic holes are sequentially filled with The card ball and the spring, the orifice of the ballistic hole is blocked by a plug, and the card ball is clamped in the snap ring groove on the bolt under the action of the spring force; The diameter of the ring is greater than the diameter of the through hole of the ring mouth, and a pull ring is arranged on the retaining ring.

The above state is the locked state of the device of the present invention. When the device of the present invention needs to be unlocked, it is only necessary to pull the latch outward through the pull ring. When the latch is pulled, the clamp ball rolls along the gentle slope of the locking ring groove at the end of the latch , as the bolt continues to be pulled out, the locking ring groove at the other end of the bolt enters into the ring opening with the locking ball again, and the locking ball is locked in the locking ring groove at this end. The outer groove wall is a vertical straight face, so the clamping ball is firmly stuck on the groove wall, thereby preventing the latch from being completely pulled out from the ring mouth.

The device of the present invention is reasonable in design, simple in structure and easy to operate, and well solves the problem that the U-shaped ring of the tool in the existing spiral nailing mode is complicated and difficult to operate and easily increases the working intensity of the operator. The device of the present invention can simplify the operation process, Improving work efficiency has certain significance.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figures 1 to 3, a portable tool U-shaped ring includes a U-shaped ring body 1 and a pin 2. The pin 2 is inserted into the ring openings at both ends of the U-shaped ring body 1, and the pin 2 is located on the U-shaped ring. The parts inside the two ring mouths of the type ring body are respectively provided with snap ring grooves 3, the groove wall of the snap ring groove 3 on the outer side is a vertical straight surface, and the groove wall on the inner side is a gentle slope The bottom of one of the ring mouths of the U-shaped ring body 1 is provided with a ballistic hole communicating with the through hole of the ring mouth, and the ballistic holes are filled with snap beads 4 and springs 5 in sequence, and the orifice of the ballistic hole is sealed by 6 plugs. Blocking, the clamping bead 4 is clamped in the clamping ring groove 3 on the latch 2 under the action of the elastic force of the spring 5; the end of the latch 2 close to the clamping bead 4 is provided with a retaining ring 7, and the diameter of the retaining ring 7 is larger than the ring opening The diameter of the through hole, the retaining ring 7 is provided with a pull ring 8.
