Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel bars, in particular to a threaded steel bar which is easy to transport. Background Art

[0002] Rebar is the common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bars is composed of HRB and the minimum yield point of the grade. There are two commonly used classification methods for rebars: one is classification by geometric shape, and the other is classification by performance. In addition, rebars can also be classified according to their use, such as ordinary steel bars for reinforced concrete and heat-treated steel bars for prestressed reinforced concrete.

[0003] According to a disclosed threaded steel bar that is convenient for bundling and docking (Announcement No.: CN214884872U), in the above application, the column on the lower surface of the threaded steel body is inserted into the adjacent threaded steel body. At this time, the lower surface of the column will first squeeze the block inside the adjacent threaded steel body, so that the block and the cross bar move to the outside of the threaded steel body. When the column continues to be inserted, the column will squeeze the load-bearing plate. When the block and the slot are in the same horizontal direction, the block enters the slot under the action of the second spring. At this time, the threaded steel body and the adjacent threaded steel body are docked, and the operation is quick and convenient.

[0004] However, during actual use of the above equipment, the rebar can only be connected in one direction. During transportation or when encountering bumps on the road, the rebar is still prone to rolling, which may cause the rebar to loosen and fall, causing damage to the rebar. In view of this, we propose a rebar that is easy to transport. Utility Model Content

[0008] Preferably, the size of the card slot matches the size of the card block, and the size of the top slot matches the size of the top column, so that when the card block is inserted into the card slot, the top column slides in the top slot.

[0009] Preferably, a locking groove matching the size of the locking block is provided on the outer wall of the limiting block, the locking block passes through the inner wall of the limiting groove, and the locking block is slidably connected to the inner wall of the locking groove, and the locking block is inserted into the locking groove to lock the limiting block.

[0010] Preferably, the end of the rotating shaft is fixedly connected to the inner wall of the steel body, and the end of the return spring away from the lock column is fixedly connected to the inner wall of the steel body, so that when the lock column moves, the connecting rod rotates around the rotating shaft.

[0011] Preferably, one end of the extrusion spring away from the clamping block is fixedly connected to the inner wall of the steel body, the outer wall of the limit block is provided with a groove and a slope, and the outer wall of the clamping block is provided with a protruding end and a slope corresponding to the groove, so that the clamping block moves when it contacts the limit block, and when the limit block leaves the clamping block, the clamping block clamps the limit block through the cooperation of the groove and the protruding end.

[0012] Preferably, a hemispherical surface is formed at one end of the lock column away from the return spring, the lock column passes through the lock slot, and is slidably connected to the inner wall of the lock slot, and the lock rod contacts the hemispherical surface of the lock column, so that the lock rod squeezes the lock column when moving in the lock slot, causing the lock column to move.

[0013] Compared with the prior art, the utility model provides a threaded steel bar that is easy to transport and has the following features:

[0014] Beneficial effects:

[0015] 1. The threaded steel bar which is easy to transport can be connected with other threaded steel bars in four directions through the limit blocks and the limit grooves. The clamping blocks in the limit grooves make the threaded steel bars connected more tightly. Through the cooperation of the clamping blocks and the clamping grooves, the top column squeezes the telescopic block to move the output end of the telescopic block into the locking groove, so that both ends of the threaded steel bar can be fixed with other threaded steel bars, and the threaded steel bars can be fixed to each other, and are not easy to roll during transportation, thereby preventing the threaded steel bars from being damaged due to falling.

[0016] 2. The threaded steel bar that is easy to transport is connected through a connecting plate, a locking block, and a locking groove. Under the action of a reset spring, the locking column inserts the locking block into the locking groove to further fix the limit block. Then, through a locking rod and a locking groove, when the locking rod is inserted into the locking groove, the locking rod contracts the telescopic block and simultaneously moves the locking column to drive the locking block to leave the locking groove, thereby unlocking the threaded steel connection and facilitating the disassembly of the threaded steel bar.
