Description

Technical Field

[0002] During rebar processing, different functions require on-site fabrication of the rebar, which inevitably involves bending.

During on-site rebar fabrication, manual operation makes it impossible to guarantee the bending diameter. Current technology still relies on measuring with a ruler, but since manual measurement cannot accurately determine the center of the bent rebar, accurate inspection of this part is impossible. To address this issue and enable specialized inspection of the bending diameter of rebar of different specifications and models, ensuring the pass rate of rebar processing, a small tool for rebar diameter inspection is proposed.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a small tool for checking the diameter of reinforcing bars, including a detection component 10 and a reinforcing bar 20 disposed on one side of the detection component 10. The detection component 10 is provided with a measuring component for measuring the diameter of the reinforcing bar 20 and a driving component for adjusting the measuring component.

[0027] In an embodiment of this utility model, the measuring component includes multiple adjusting rods 1004 disposed on the detection member 10, multiple measuring scales 1005 disposed on the adjusting rods 1004, the measuring scales 1005 being provided with scale markings for reading the diameter, at least two measuring scales 1005 being provided, and in addition to reading the diameter, the measuring scales 1005 also serving as a limit to improve the stability of the adjusting rods 1004, preventing the adjusting rods 1004 from rotating during adjustment, a fixing member 1006 disposed at one end of the adjusting rods 1004, a support rod 1008 disposed at the other end of the adjusting rods 1004, and a connecting plate 1009 disposed at the other end of the support rod 1008.

[0028] In an embodiment of this utility model, the driving assembly includes a screw 11 disposed inside the detection member 10, an adjusting ring 1101 disposed outside the screw 11, and a plurality of hinge plates 1104 disposed between the adjusting ring 1101 and a plurality of connecting plates 1009. During the up-and-down movement of the adjusting ring 1101, the adjusting ring 1101 pushes and pulls the adjusting rod 1004 through the hinge plates 1104, thereby achieving the effect of adjusting the diameter. The number of hinge plates 1104 is equal to the number of connecting plates 1009.

[0029] In this embodiment of the present invention, a wristband 30 is provided on one side of the testing piece 10 for easy handling of the testing piece 10. A slot is provided on one side of the fixing piece 1006, and the arc-shaped side of the reinforcing bar 20 is engaged with the slot. When it is necessary to measure the diameter of the arc portion of the reinforcing bar 20, the screw 11 is rotated until the slot on the fixing piece 1006 is engaged with the arc portion of the reinforcing bar 20. At this time, the diameter of the arc portion of the reinforcing bar 20 can be determined by reading the value on the measuring scale 1005. Accurate measurement can effectively improve the pass rate of the processing of the reinforcing bar 20.

[0030] In an embodiment of this utility model, a connecting block 1007 is provided at one end of the adjusting rod 1004, and a support rod 1008 is provided on one side of the connecting block 1007. The top of the detection element 10 is provided with a plurality of circumferentially equidistant sliding grooves 1001. The support rod 1008 passes through the sliding grooves 1001 and extends to the top of the detection element 10. The sliding grooves 1001 facilitate the movement of the adjusting rod 1004 by pushing and pulling the support rod 1008. The number of sliding grooves 1001 is equal to the number of support rods 1008.

[0031] In an embodiment of this utility model, the side of the detection element 10 is provided with a plurality of fixing holes 1002 that are circumferentially equidistant, and the side of the detection element 10 is provided with a plurality of sets of limiting grooves 1003, which are connected to the fixing holes 1002, and the number of each set of limiting grooves 1003 is at least two.

[0032] It should be noted that the number of fixing holes 1002 is equal to the number of adjusting rods 1004. The adjusting rods 1004 are slidably connected to the fixing holes 1002, which facilitates the movement of the adjusting rods 1004. When the adjusting rods 1004 move closer to the screw 11, the diameter measured by the fixing member 1006 decreases. When the adjusting rods 1004 move away from the screw 11, the diameter measured by the fixing member 1006 increases. The measuring scales 1005 are slidably connected to the limiting grooves 1003, and the number of measuring scales 1005 is equal to the number of limiting grooves 1003.

[0033] In an embodiment of this utility model, a plurality of first fixing brackets 1102 are provided on the outer side of the adjusting ring 1101. The first fixing brackets 1102 are fixedly disposed on the outer periphery of the adjusting ring 1101. The plurality of first fixing brackets 1102 are distributed equidistantly in a circle. The number of first fixing brackets 1102 is equal to the number of connecting plates 1009. A second fixing bracket 1103 is provided on one side of the connecting plate 1009. The second fixing bracket 1103 is fixedly disposed on the side of the connecting plate 1009 near the screw 11.

[0034] It is understood that the two ends of the hinge plate 1104 are respectively set on the corresponding first fixed frame 1102 and second fixed frame 1103, and the two ends of the hinge plate 1104 are rotatably connected to the first fixed frame 1102 and the second fixed frame 1103 respectively. The top end of the screw 11 is provided with a handle 1105, and the handle 1105 is fixedly set on the top of the handle 1105.

[0035] It should be emphasized that a threaded hole is provided on one side of the adjusting ring 1101, and the screw 11 is threaded into the threaded hole. When the screw 11 is rotated clockwise, the adjusting ring 1101 moves upward. At this time, the hinge plate 1104 retracts towards the side closer to the screw 11 and pulls the adjusting rod 1004 towards the inside of the detection element 10. At this time, the diameter measured by the fixing element 1006 becomes smaller. When the screw 11 is rotated counterclockwise, the adjusting ring 1101 moves downward. At this time, the hinge plate 1104 extends and retracts away from the screw 11 and pushes the adjusting rod 1004 towards the outside of the detection element 10. At this time, the diameter measured by the fixing element 1006 becomes larger. A through hole is provided at the top center of the detection element 10, and the screw 11 passes through the through hole.

[0036] Specifically, the working principle of this tool for checking the diameter of reinforcing bars is as follows:

[0037] When it is necessary to measure the diameter of the bent portion of the reinforcing bar 20, the screw 11 is rotated until the slot on the fixing member 1006 engages with the arc portion of the reinforcing bar 20. Specifically, rotating the screw 11 clockwise moves the adjusting ring 1101 upward. At this time, the hinge plate 1104 retracts towards the side closer to the screw 11 and pulls the adjusting rod 1004 towards the inside of the detection member 10. At this time, the diameter measured by the fixing member 1006 becomes smaller. Rotating the screw 11 counterclockwise moves the adjusting ring 1101 downward. At this time, the hinge plate 1104 extends and retracts away from the screw 11 and pushes the adjusting rod 1004 towards the outside of the detection member 10. At this time, the diameter measured by the fixing member 1006 becomes larger. When the slot on the fixing member 1006 engages with the arc portion of the reinforcing bar 20, the diameter of the arc portion of the reinforcing bar 20 can be determined by reading the value on the measuring scale 1005. Accurate measurement can effectively improve the pass rate of the reinforcing bar 20 processing.
