Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe protective covers, in particular to a steel pipe protective cover component. Background Art

[0002] In order to facilitate the installation and docking of steel pipes on the construction site and ensure the quality, the steel pipes are required to be processed with welding grooves before leaving the factory. However, the end faces of the steel pipes will inevitably be damaged during transportation and lifting and unloading, thus affecting the construction. Therefore, they must be protected before leaving the factory. Therefore, steel pipe protection sleeves are used to cover both ends of the steel pipes to protect the steel pipes during storage and transportation.

[0003] However, the existing steel pipe protective sleeve is made of plastic or rubber material, and has corresponding threads on the inner wall or the outer wall. At the same time, the threads are engaged and installed at one end of the steel pipe. Due to the influence of its own material, it will cause wear and tear each time it is used, resulting in size changes, which will make it impossible to use it again. In addition, each specification is specific and cannot adapt to steel pipes of multiple specifications. Utility Model Content

[0004] The purpose of the present utility model is to provide a steel pipe protective cover assembly to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a steel pipe protective cover assembly, comprising a main body, a frame installed in the main body, a screw-in block installed in the middle of the frame, and several movable blocks installed at intervals on the four edges of the frame. An upper circular hole is provided on the upper side of the frame, a lower circular hole is provided on the bottom of the frame, and a square hole is provided on the outer wall of the frame. A plurality of regularly arranged arc rails are provided on the outer wall of the screw-in block, a cylindrical block is symmetrically provided in the middle of the screw-in block, a thread is provided on the outer wall of the screw-in block, a cylinder is installed on the outer wall of the movable block, an arc-shaped opening is provided at one end of the movable block, and a rubber pad of the same specifications is installed at the arc-shaped opening. At the same time, the interior of the frame is set to be hollow, an inner edge layer is formed between the lower circular hole and the inner wall of the frame, and a sliding rail is provided on the outer wall of the inner edge layer.

[0006] Preferably, the outer contour of the frame is cylindrical, and the upper circular hole and the lower circular hole are coaxial, and the size of the upper circular hole is larger than that of the lower circular hole.

[0007] Preferably, the precession block is cylindrical, the size trend of the arc-shaped rail is oblique, and the other end of the arc-shaped rail faces the center of the precession block.

[0008] Preferably, the cylindrical block protrudes from the screw-in block, and the cylindrical blocks are symmetrically arranged around the center of the screw-in block.

[0009] Preferably, the positions of the square hole and the slide rail correspond to each other, the movable block is inserted into the square hole, and the movable block is slidably connected to the square hole and the slide rail respectively.

[0010] Preferably, the cylinder is inserted into the arc-shaped rail, and the movable block is slidably connected through the cylinder and the arc-shaped rail.

[0011] Preferably, the height difference between the inner edge layer and the upper circular hole is greater than that of the screw-in block, and the height of the cylinder occupies half the height of the inner wall of the frame.

[0012] Preferably, threads are provided on the inner wall of the frame, and the threads on the frame and the screw-in block are engaged with each other.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the utility model, the steel pipe is inserted into the lower circular hole, and the screw-in block is rotated to screw it in along the thread on the inner wall of the frame. At the same time, the movable block moves along the arc rail through the cylinder during the rotation of the screw-in block, and the movable block moves inward along the slide rail at the bottom. The area of the circular area formed between adjacent movable blocks is reduced, and then the arc-shaped mouth of the movable block with a rubber pad is pressed against the steel pipe. At the same time, there is a distance between the thread on the inner wall of the frame and the movable block, so the screw-in block will not press against the movable block. The deformation characteristics of the rubber block are used to squeeze on the steel pipe thread and generate sufficient friction to fix the protective cover on the steel pipe. The internal rubber block can be replaced later. The moving distance of the movable block can be adjusted by properly rotating the screw-in block to avoid the problem of being unable to use it again due to wear. At the same time, it is suitable for steel pipes of multiple specifications. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: a steel pipe protective cover assembly, comprising a main body 1, a frame 2 is installed in the main body 1, a screw-in block 3 is installed in the middle of the frame 2, and several movable blocks 4 are installed at intervals on the edges of the four sides of the frame 2. The upper side of the frame 2 is provided with an upper circular hole 21, the bottom of the frame 2 is provided with a lower circular hole 22, and the outer wall of the frame 2 is provided with a square hole 23. The outer wall of the screw-in block 3 is provided with several regularly arranged arc rails 31, the middle of the screw-in block 3 is symmetrically provided with a cylindrical block 32, the outer wall of the screw-in block 3 is provided with a thread 33, a cylinder 41 is installed on the outer wall of the movable block 4, one end of the movable block 4 is provided with an arc opening 42, and a rubber pad 43 of the same specification is installed at the arc opening 42. At the same time, the interior of the frame 2 is set to be hollow, and an inner edge layer 5 is formed between the lower circular hole 22 and the inner wall of the frame 2, and a sliding rail 51 is provided on the outer wall of the inner edge layer 5.

[0022] The outer contour of the frame 2 is cylindrical, and the upper circular hole 21 and the lower circular hole 22 are coaxial, and the size of the upper circular hole 21 is larger than that of the lower circular hole 22. The screw-in block 3 is cylindrical, and the size trend of the arc rail 31 is oblique, and the other end of the arc rail 31 is toward the center of the screw-in block 3. The cylindrical block 32 protrudes from the screw-in block 3, and the cylindrical block 32 is symmetrically arranged at the center of the screw-in block 3. The positions of the square hole 23 and the slide rail 51 correspond to each other, and the movable block 4 is inserted into the square hole 23. The movable block 4 is respectively slidably connected to the square hole 23 and the slide rail 51. The cylinder 41 is inserted into the arc rail 31, and the movable block 4 is slidably connected to the arc rail 31 through the cylinder 41. The height difference between the inner edge layer 5 and the upper circular hole 21 is greater than that of the screw-in block 3, and the height of the cylinder 41 accounts for half the height of the inner wall of the frame 2. The inner wall of the frame 2 is provided with a thread 33 , and the frame 2 and the thread 33 on the screw-in block 3 are engaged with each other.

[0023] Working principle: Align the lower circular hole 22 with one end of the steel pipe, and insert one end of the steel pipe into the lower circular hole 22 of the frame 2. During this period, it should be noted that one end of the steel pipe cannot go beyond the lower circular hole 22, so that the edges of the steel pipe and the lower circular hole 22 are flush with each other, and then screw the screw-in block 3 into the upper circular hole 21, so that the screw-in block 3 and the thread 33 on the inner wall of the frame 2 are engaged, so that the screw-in block 3 is screwed along the frame 2. At the same time, during the rotation of the screw-in block 3, the relative position of the arc rail 31 on its outer wall changes, so The cylindrical block 32 moves along the arc rail 31, and at the same time, the screw-in block 3 moves along the slide rail 51 toward the center of the lower circular hole 22. The area of the circular region formed between adjacent movable blocks 4 decreases, and then the arc-shaped opening 42 of the movable block 4 equipped with a rubber pad 43 presses against the steel pipe. At the same time, there is a gap between the thread 33 on the inner wall of the frame 2 and the movable block 4, so the screw-in block 3 will not press against the movable block 4. The deformation characteristics of the rubber pad 43 are used to squeeze on the steel pipe and generate sufficient friction to fix the protective cover on the steel pipe.
