DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1: Refer to the attached specification Figure 1-4 The utility model is a steel bar binding device for construction, comprising a cylinder 1, the inner cavity of the cylinder 1 is sleeved with a cylinder 2, the cylinder 2 2 is hollow, the surface of the cylinder 2 is through-shaped with a double-strand spiral groove 3, the two grooves of the double-strand spiral groove 3 are inserted with a cross bar 4, the two ends of the cross bar 4 are fixedly installed with spherical blocks 5, and the bottom of the cylinder 2 is installed with a hook 6;

[0031] A support ring 14 is rotatably connected to the bottom of the cylinder 2 through a bearing 15. Four support arms 7 for positioning the steel bars are installed at the bottom of the support ring 14. The transverse projection length of the support arms 7 is greater than the transverse projection length of the hook 6. The other four support arms 7 are arranged in a cross shape from a longitudinal position, because the steel bars are also placed in a cross shape when placed. Figure 1 , 2 As shown, a U-shaped clamping block is installed at the bottom of the support arm 7 to position the steel bar by clamping.

[0032] It should be noted that, when the iron wire is passed through the steel bar, the support arm 7 is first deflected to allow the hook 6 to hook the iron wire, and then the U-shaped block at the bottom of the support arm 7 is clamped at the crossed steel bars to form a positioning, and the cylinder 1 is pushed by pressing the hand or shoulder, and the cross bar 4 slides in the two grooves of the double-strand spiral groove 3. Since the cylinder 1 moves vertically downward, the cylinder 2 is rotated on the top of the support ring 14 through the bearing 15, so that the hook 6 rotates and knots the iron wire. The traditional tooth groove is pulled to make the hook 6 rotate, and the tooth groove edge is easy to wear and easy to get stuck. This solution uses the cross bar 4 The column structure is subjected to downward force in the two grooves at the same time. Even if the surface of the double-strand spiral groove 3 is worn, it will not affect the rotation of the cylinder 2. Compared with the traditional tooth groove structure, this solution is more durable. In addition, the traditional pull rod method makes it easier for the unfixed steel bars to be misplaced, and the upper and lower arms are prone to soreness. This solution adopts a propulsion method to improve it, because the thrust can be assisted by the gravity of the tilted body, which is more labor-saving. At the same time, the support arm 7 can position the steel bars. Since the steel bars are placed crosswise one above and one below, when the support arm 7 presses the steel bars, the other hand can be used to pull the cross steel bars below as support;

[0033] In addition, every two opposing support arms 7 form a group, and the two groups of support arms 7 can be matched in a manner of one high and one low. The difference in projection height between the two is the diameter of the steel bar. Because the steel bars are placed one up and one down, the probability of the product tilting can be reduced.

[0034] As the installation and angle adjustment scheme of the hook 6 in the first embodiment, Figure 3 As shown, an adjusting ball 8 is fixedly installed on the top of the hook 6, and a support rod 9 and an externally threaded cylinder 11 are fixedly installed on the bottom of the cylinder body 2, wherein the externally threaded cylinder 11 is sleeved on the outside of the support rod 9, and a spherical clamp 10 is fixedly installed on the bottom of the support rod 9, wherein the clamp shape of the spherical clamp 10 is formed into multiple arc-shaped rod-shaped structures by a plurality of slots, so that it can have a certain deformation, and the spherical clamp 10 reaches a clamp state under an annular force. The external thread of the externally threaded cylinder 11 is connected with an internally threaded cylinder 12, and a limiting ring 13 for pressing the spherical clamp 10 is fixedly installed at the bottom of the inner cavity of the internally threaded cylinder 12, as shown in FIG. Figure 3As shown, a circular groove is provided at the bottom of the internal threaded barrel 12, and the circular groove is a space for adjusting the hook 6. When the internal threaded barrel 12 is loosened, the hook 6 can adjust the tilt angle, which is beneficial to the hook usage habits of different operators.

[0035] As a further solution of the spring member 16 in the first embodiment, a top cover 17 is mounted on the top of the cylinder body 1 by means of a snap connection. Figure 1-2 As shown, the clamping connection between the cylinder 1 and the top cover 17 is a cylindrical plug-in structure for quick disassembly and assembly. The bottom of the top cover 17 and the top of the cylinder 2 are installed with bolt crimping terminals 18, wherein the structure of the bolt crimping terminals 18 is similar to the wiring terminals in the prior art, except that this solution is not used for conducting electricity, but only for disassembling and fixing the spring member 16; the spring member 16 is installed in the inner cavity of the cylinder 1 by means of the bolt crimping terminals 18 in a single-head fixed or double-head fixed manner, and the spherical block 5 is installed on the bottom edge of the cylinder 1 by bolts; as shown Figure 5 As shown, the spring member 16 includes a tension spring 1601 or a spring 1602, and the tension spring 1601 is fixed to the inner cavity of the cylinder body 1 at both ends through the bolt crimping terminal 18; the spring 1602 is fixed to the inner cavity of the cylinder body 1 at one end or at both ends through the bolt crimping terminal 18.

[0036] It should be noted that Figure 5 The tension spring 1601 is used to pull the cylinder 1 to rotate the hook 6, and the spring 1602 is used to push the cylinder 1 to rotate the hook 6. The tension spring 1601 plays a pulling role, and the spring 1602 plays an elastic role. In the scheme of pulling by the tension spring 1601, the spring member 16 is fixed with two ends, that is, one end is fixed to the bolt crimping terminal 18 at the top of the cylinder 2, and the other end is fixed to the bolt crimping terminal 18 at the bottom of the top cover 17. Under normal circumstances, the tension of the spring member 16 keeps the cylinder 1 in a state of completely sleeved with the cylinder 2, pulling the cylinder 1 until the tension spring 1601 is like Figure 2 state, the hook 6 rotates along with it, and when pulled, the tension spring 1601 will not only contract up and down, but also rotate and twist. The characteristics of the spring part are torsionalness and elasticity, so it does not affect the actual use. Finally, the hook 6 is pulled out from the wire knot, the cylinder 1 is loosened, and the tension spring 1601 is deformed and restored; the spring 1602 is the usage scheme in embodiment 1, that is, the propulsion scheme. The spring 1602 is used to assist in pushing the cylinder 1 back to its original position, which is conducive to reciprocating operation. Therefore, the spring 1602 can be used normally with single-head or double-head fixation.

[0037] The second embodiment based on the first embodiment is used to protect the wire knot for binding steel bars, that is, a further scheme structure of the hook 6, wherein the hook 6 includes a hook rod 61, the hook rod 61 is fixedly installed at the bottom of the adjusting ball 8, a hook plate 62 is fixedly installed at the bottom of the hook rod 61, the hook plate 62 is arranged in a cone shape, a cone cylinder 63 is fixedly installed in the middle of the hook plate 62, a hollow groove for placing the wire knot formed by binding steel bars is provided at the bottom of the cone cylinder 63, and protrusions 64 for preventing the wire from falling off are fixedly installed on both sides of the hook plate 62; wherein the shape of the hook plate 62 is conducive to inserting into the hole of the wire knot, and the plate-like structure is to prevent the support arm 7 from not supporting well, and the hook plate 62 is directly pressed onto the surface of the steel bar and the wire. At this time, the plate-like structure can better rotate on the surface of the steel bar, and the hollow groove of the cone cylinder 63 is used to reserve space for placing the wire knot to prevent the plate-like structure of the hook plate 62 from crushing it.

[0038] like Figure 6-8 As shown, a liquid storage cotton 19 is placed in the inner cavity of the cylinder 2, and the liquid storage cotton 19 is filled with anti-rust liquid. A complete and interconnected drainage groove is opened in the hollow groove of the cylinder 2, the support rod 9, the adjusting ball 8, the hook rod 61, the hook plate 62 and the cone 63, wherein the anti-rust liquid includes a liquid amino alcohol steel bar rust inhibitor or a steel bar rust remover. The rust inhibitor is mainly used to prevent metal oxidation corrosion, while the rust remover is used to remove the rust that has already appeared. Although the two have similarities, there are still different differences in efficacy and use methods; after the cross bar 4 is pressed onto the surface of the liquid storage cotton 19, as shown Figure 6 As shown, the bottom of the cylinder 2 has a notch, which is connected to the drainage groove. Finally, the liquid flows from the drainage groove to the bottom of the cone 63, achieving the effect of rust removal or rust prevention on the wire nodules and steel bar connections. The anti-rust liquid is directly injected into the surface of the liquid storage cotton 19 through the double-strand spiral groove 3.
