Description

Technical Field

[0001] The utility model belongs to the technical field of angle measurement, in particular to a device for measuring the bending angle of a steel bar. Background Art

[0002] Rebar refers to steel used in reinforced concrete and prestressed concrete. Its cross-section is round, or sometimes square with rounded corners. It includes plain, ribbed, and twisted bars. Rebar for reinforced concrete refers to the straight or coiled steel used for reinforced concrete reinforcement. It comes in two shapes: plain and deformed, and is delivered as either straight bars or coils.

[0003] After the steel bar is bent, the bending angle of the steel bar needs to be measured. When measuring the bending angle, a universal measuring ruler is usually used to measure the angle. However, the universal measuring ruler cannot be effectively fixed when measuring the steel bar angle, which makes the measurement more troublesome. For this reason, we propose a steel bar bending angle measuring device. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a steel bar bending angle measuring device, which effectively solves the problems raised in the background technology.

[0006] The clamping seat includes a shell and a clamping hook. The clamping hook is located inside the shell. A gear is provided inside the shell. A return spring is provided at the bottom of the gear. An adjustment seat is provided on the top of the gear. The clamping hook includes a rod body. Tooth grooves are evenly opened on one side of the rod body. The tooth grooves are engaged with the gear. A hook body is provided at one end of the rod body.

[0011] Preferably, the interior of the laminating plate is evenly provided with action grooves, and rollers are provided inside the action grooves.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The tooth groove on one side of the rod body is moved by rotating the gear, so that the gear drives the rod body to extend forward when rotating, and the hook body is driven to move forward by the forward extension of the rod body. When the adjustment seat is relaxed, the return spring at the bottom of the gear can automatically relax the gear when the adjustment seat is relaxed, so that the hook body automatically contracts, so that the hook body can better clamp the steel bar;

[0024] The clamping seat 20 includes a shell 21 and a clamping hook 22. The clamping hook 22 is located inside the shell 21. A gear 23 is provided inside the shell 21. A return spring 24 is provided at the bottom of the gear 23. An adjustment seat 25 is provided on the upper part of the gear 23. The clamping hook 22 includes a rod body 26. A tooth groove 27 is evenly opened on one side of the rod body 26. The tooth groove 27 is engaged with the gear 23. A hook body 28 is provided at one end of the rod body 26. When the device is in use, the clamping seat 20 can be opened. After the clamping seat 20 is opened, the bonding plate 10 is bonded to the steel bar, so that the clamping seat 20 clamps and fixes the steel bar, and the position of the adjustment plate 30 is adjusted so that the adjustment plate 30 is bonded to the bending part of the steel bar. When the adjustment plate 30 is adjusted, the adjustment plate 30 is bonded to the bending part of the steel bar. When the plate 30 is fitted with the steel bar, the angle plate 40 can be observed to measure the bending angle of the steel bar. When the clamping seat 20 is clamping, the adjusting seat 25 can be rotated by rotating the adjusting seat 25. The rotation of the adjusting seat 25 drives the gear 23 to rotate. The rotation of the gear 23 drives the tooth groove 27 on one side of the rod body 26 to dial the gear 23 so that the gear 23 drives the rod body 26 to extend forward when rotating. The forward extension of the rod body 26 drives the hook body 28 to move forward. By loosening the adjusting seat 25 and the return spring 24 at the bottom of the gear 23, the gear 23 can be automatically loosened when the adjusting seat 25 is loosened, so that the hook body 28 can automatically retract. The hook body 28 can better clamp the steel bar, and a storage groove is provided inside the bonding plate 10. The shape of the storage groove matches the shape of the adjustment plate 30. The upper part of the adjustment plate 30 is provided with a mounting groove, and an adsorption block is installed inside the mounting groove. The upper part of the bonding plate 10 is provided with a magnetic block, and the adsorption block and the magnetic block are adsorbed. By providing the storage groove, the adjustment plate 30 can be effectively stored, so that the adjustment plate 30 can be better folded and stored. By providing the mounting groove, the position of the adsorption block can be limited. By providing the adsorption block, the adsorption block will be adsorbed with the magnetic block when the adjustment plate 30 is stored, so that the position of the adjustment plate 30 can be better limited when the adjustment plate 30 is stored. The adjusting plate 30 includes a plate body 31, and a rotating rod 32 is provided on the upper part of the plate body 31. The plate body 31 is connected to the bonding plate 10 through the rotating rod 32, and a pointing pin 33 is provided on the front side of the rotating rod 32. When the adjusting plate 30 is in use, the position of the plate body 31 can be limited by providing the rotating rod 32, so that the plate body 31 can be rotated better, and when the rotating rod 32 is rotated, it will drive the pointing pin 33 to rotate better, so that the rotation of the pointing pin 33 can point to the angle better when the plate body 31 rotates. The upper part of the bonding plate 10 and the left side of the adjusting plate 30 are both provided with bonding grooves, and the shape of the bonding groove is arc-shaped. Through the arc-shaped bonding groove,The bonding plate 10 can be better bonded to the steel bar, and the bonding plate 10 can be better bonded to the steel bar for measurement. The arc groove set on one side of the adjustment plate 30 can make the adjustment plate 30 better bonded to the bend of the steel bar. The bonding plate 10 has evenly opened working grooves inside, and rollers are set inside the working grooves. The positioning of the rollers can be effectively limited by the provision of the working grooves. The provision of the rollers can better adjust the position of the bonding plate 10 when bonding the bonding plate 10 to the steel bar.

[0025] Working principle: When the device is in use, the clamping seat 20 can be opened. After the clamping seat 20 is opened, the bonding plate 10 is bonded to the steel bar, so that the clamping seat 20 can clamp and fix the steel bar, and the position of the adjustment plate 30 can be adjusted so that the adjustment plate 30 is bonded to the bending part of the steel bar. When the adjustment plate 30 is bonded to the steel bar, the angle plate 40 can be observed to measure the bending angle of the steel bar. When the clamping seat 20 is clamping, it can be rotated by rotating the adjustment seat 25. The rotation of the adjusting seat 25 drives the gear 23 to rotate, and the rotation of the gear 23 shifts the tooth groove 27 on one side of the rod body 26, so that the gear 23 drives the rod body 26 to extend forward when rotating, and the forward extension of the rod body 26 drives the hook body 28 to move forward. By loosening the adjusting seat 25, the return spring 24 at the bottom of the gear 23 can automatically loosen the gear 23 when the adjusting seat 25 is loosened, so that the hook body 28 automatically contracts, so that the hook body 28 can better clamp the steel bar.
