As shown in fig. 1 and 2, the present utility model provides a straight tube protecting device, including: the two slips 2 are arc-shaped on the opposite sides of the slips 2, one ends of the slips 2 are rotatably connected, and the other ends of the slips are detachably connected through a lock catch 6, so that the slips 2 and the lock catch form a through hole capable of tightly holding the straight pipe 1; an external ring 3 is arranged on the outer side of each slip 2, and the two external rings 3 are semicircular and are symmetrically arranged about the center of the through hole; a connecting rod 4 is arranged between the external ring 3 and the slips 2, so that the external ring 3 is arranged at a certain distance from the slips 2.

In this technical scheme, two slips 2 pass through hasp 6 forms the through-hole that can hug closely straight tube 1, realizes hugging closely straight tube 1. The external rings 3 on the outer sides of the two slips 2 can be conveniently and normally gripped manually, and for short pipes, two people can hold the external rings 3 by one group to lift the pipe; for the long pipe, when the lifting is needed, the lifting rope can be fixed on the external ring 3, so that the problem that the lifting rope is bound on the wall of the straight pipe and easily slides is solved, and the construction safety is improved. The straight pipe protection device is detachably connected through the lock catch 6, and the universality is high. The straight pipe protection device can enlarge the distance between two straight pipes, prevent collision damage and facilitate protection of male union, female union and pipe body paint. Because the external ring 3 is semicircular, the straight pipe protecting device can also serve as a roller in a short distance so as to roll the straight pipe. In the transportation process, the straight pipe protection device can also serve as a bracket or a stop block so as to fix the straight pipe and prevent the straight pipe from moving in series.

In another embodiment, the lock 6 includes a rotating body 61 and a pressing plate 63, the rotating body 61 is rotatably connected with the outer side of one of the slips 2, a handle 64 is fixedly disposed on one side of the rotating body 61, and a circular arc-shaped limit protrusion 62 is fixedly disposed on the other side of the rotating body 61; the pressing plate 63 is fixedly connected with one of the slips 2, one side covers the joint of the two slips 2, a groove matched with the limit protrusion 62 is formed in the other side, and the handle 64 drives the rotator 61 to rotate, so that the limit protrusion 62 is clamped in or separated from the groove.

As shown in fig. 2, the side of the pressing plate 63 facing the slips 2 is a cambered surface with a matched shape at the joint of the two slips 2 so as to cover the joint of the two slips 2. The pressing plate 63 may also be formed by splicing two sub-plates, where the two sub-plates are respectively fixed on the two slips correspondingly, and one sides of the two sub-plates facing away from the slips are respectively grooved and jointly form the grooves. The rotator 61 may be rotatably connected to the slip 2 through a rotation shaft, so that the rotator 61 may rotate relative to the slip 2. The limit protrusion 62 may be formed integrally with the rotor 61, and both may form a cam-like structure; the handle 64 drives the rotator 61 to rotate towards the center of the through hole, namely, the rotator rotates clockwise in fig. 2, when the handle approaches to the slips 2, the limiting protruding portions 62 are clamped into the grooves to compress the compressing plates 63, the compressing plates 63 further compress two slips 2, and at the moment, the two slips 2 can hold the straight pipe 1 tightly. When the handle 64 is required to be detached, the handle is pulled in the opposite direction, so that the rotator 61 rotates in a direction away from the center of the through hole, that is, in fig. 2, the limiting protrusion 62 leaves the groove, the pressing force applied to the pressing plate 63 is removed, and the corresponding connection parts of the two slips 2 can be separated. The other ends of the two slips 2 can be connected by a hinge 5 to achieve a rotational connection. Further, the center of the groove is opposite to the joint of the two slips 2. When the limit protrusion 62 rotates along with the rotator 61 to be clamped into the groove, the pressing force can just act on the joint of the two slips 2, so as to ensure the stability of the connection of the two slips 2.
