Technical Field

[0001] The utility model relates to the technical field of steel bar calipers, in particular to a steel bar caliper. Background Art

[0002] A rebar caliper is a tool specifically used to measure the diameter and length of rebar. It is usually made of steel or plastic, about 20 cm long, and the two ends can move freely to accurately measure the size of the rebar. Rebar calipers play an important role in rebar processing and installation, helping construction workers to accurately arrange rebars and improve construction quality and work efficiency. When using a rebar caliper, you need to pay attention to factors such as the clarity and accuracy of the scale, as well as the flatness of the rebar surface. The correct way to use it includes opening the caliper, placing the two ends on both ends of the rebar, and gently moving the caliper until it touches the rebar to obtain accurate measurement results.

[0003] During the construction process of tying steel bars, the spacing between the steel bars needs to be measured. The traditional steel bar caliper needs to measure the spacing every time the steel bars are tied, which is very time-consuming and is not convenient to measure the spacing after the steel bars are tied.

[0004] Therefore, a steel bar caliper is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-3 The present embodiment provides a steel bar caliper, including a crowbar head 1, a caliper 2 is installed at one end of the crowbar head 1, nine groups of positioning mechanisms 3 are slidably installed on the caliper 2, a hook 31 is installed at the bottom of the positioning mechanism 3, a bent pipe 32 is fixedly connected to the top of the hook 31, and the bent pipe 32 is in a vertical state with the caliper 2. During the use of the steel bar caliper, the nine groups of positioning mechanisms 3 are slid on the caliper 2 according to the spacing between the steel bars to separate the spacing of the steel bars installed by the nine groups of positioning mechanisms 3. Each time the steel bars are tied, the steel bars are directly hung on the hooks 31 on one group of positioning mechanisms 3 to carry out construction, so that nine groups of steel bars with equal spacing can be quickly tied, and there is no need to manually measure the spacing with a ruler each time the steel bars are tied, thereby effectively improving the tying efficiency of the steel bars and facilitating the spacing measurement of the tied steel bars.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, the crowbar head 1 is made of steel material, and a U-shaped groove is provided at the bottom of the crowbar head 1, so as to adjust the position of the steel bars whose measured spacing is unqualified.

[0026] In this embodiment, if Figure 1 and Figure 3 As shown, a limit plate 33 is fixedly installed at one end of the top of the curved tube 32, and one side of the limit plate 33 is in contact with the outer side of the caliper 2. A reference plate 34 is fixedly installed between the bottom of the outer side of the limit plate 33 and the inner fold of the curved tube 32, and one end of the reference plate 34 is in contact with the scale line of the caliper 2. The reference plate 34 can be used to accurately adjust the moving distance of the curved tube 32 to avoid errors caused by visual inspection.

[0027] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, a threaded barrel 35 is fixedly installed at the center of the limit plate 33, and a screw 36 is threadedly connected to the inner side surface of one end of the threaded barrel 35. The threaded barrel 35 passes through the slide groove 21 on the caliper 2 and is connected to the screw 36, and the threaded barrel 35 and the screw 36 are both slidably connected to the inner side of the slide groove 21, so that the positioning mechanism 3 can adjust the spacing by sliding on the caliper 2.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, a rotating buckle 37 is installed at one end of the screw rod 36. When the rotating buckle 37 rotates clockwise, it can drive the screw rod 36 to be tightened on the inner side of the threaded tube 35. After the screw rod 36 and the threaded tube 35 are tightened, the limit plate 33 and the rotating buckle 37 are clamped on both sides of the caliper 2. Therefore, after the spacing of the positioning mechanism 3 is adjusted, the position of each positioning mechanism 3 can be fixed by tightening the screw rod 36 through the rotating buckle 37.

[0029] Working principle: When the steel bar caliper is in use, firstly, the nine groups of positioning mechanisms 3 are slid in the slide groove 21 using the threaded tube 35 according to the spacing between the steel bars. The moving distance of the curved pipe 32 can be accurately adjusted using the reference plate 34 to avoid errors caused by visual inspection and to achieve equal spacing of the nine groups of positioning mechanisms 3. Then, after adjusting the spacing of the positioning mechanisms 3, the position of each positioning mechanism 3 can be fixed by tightening the screw 36 by rotating the buckle 37. Each time the steel bars are tied, the steel bars can be directly hung on the hooks 31 on a group of positioning mechanisms 3 to carry out construction. In this way, nine groups of equally spaced steel bars can be quickly tied. There is no need to measure the spacing with a ruler each time the steel bars are tied, thereby effectively improving the steel bar tying efficiency and facilitating the spacing measurement of the tied steel bars.
