AI Technical Summary
In the existing technology, the connection stability between the locking nut and the locking body is poor, which leads to unstable binding of the reinforcing bars and poses a risk of loosening.
A steel bar connection component was designed. By setting a pair of arc-shaped locking plates at both ends of the locking body, the locking plates can be pushed outward under the action of external tools and abut against the locking nut for limitation. Through the engagement of the locking ratchet ring and the limiting ratchet ring, the rotation of the locking nut in the loosening direction is restricted, thereby enhancing the locking stability.
This effectively reduces the risk of the locking nut loosening and improves the binding stability of the reinforcing bars and the overall stability of the connecting components.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction, and in particular to a steel bar connection component. Background Technology
[0002] Reinforcing bar connectors are important components used to connect reinforcing bars in building structures, ensuring the integrity and load-bearing capacity of the structure. Currently, cross couplers are commonly used to tie and fix two reinforcing bars together.
[0003] The cross-shaped fastener in the relevant technology usually includes a locking body, a locking washer, and two locking nuts. The locking body is U-shaped, with the locking washer passing through both ends of the locking body, and the two locking nuts are threaded onto the corresponding ends of the locking body.
[0004] When it is necessary to bind two cross-shaped steel bars, mate the locking body with the two steel bars respectively, then pass the locking washers through both ends of the locking body, and then install the two locking nuts on the corresponding ends of the locking body. Finally, tighten the two locking nuts to bind the two steel bars.
[0005] However, the connection stability between the locking nut and the locking body in the relevant technology is poor. When the reinforcing bar twists, there is a risk that the locking nut will loosen, which will affect the binding stability of the reinforcing bar and needs to be improved. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel bar connection component that can reduce the risk of locking nut loosening, thereby improving the binding stability of steel bars.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel bar connection component, including a locking body, a locking washer and two locking nuts. The two ends of the locking body are respectively integrally formed with a pair of arc-shaped locking pieces. The concave surfaces of each pair of locking pieces are arranged opposite to each other. The locking pieces can be pushed outward under the action of an external tool and abut against and limit the locking nut at the end away from the locking washer.
[0008] Optionally, each of the locking nuts is provided with a limiting slope at the end away from the locking washer for the corresponding locking piece to abut against.
[0009] Optionally, a guide groove is provided at the connection position between the locking piece and the latch body, so that the locking piece can be smoothly opened outward along the corresponding guide groove.
[0010] Optionally, each pair of locking plates is provided with a guide ramp on the side away from each other, so that the locking nut can be smoothly fitted onto the corresponding end of the locking body.
[0011] Optionally, the locking washer is provided with two elastic locking ratchet rings, and each locking nut is fixedly connected with a limiting ratchet ring, and the limiting helical ring can engage with the corresponding locking ratchet ring to restrict the locking nut from rotating in the direction of loosening.
[0012] Optionally, each of the locking ratchet rings is fixedly connected to a set of limiting posts, and the locking pad is provided with two sets of limiting grooves, and each set of limiting posts can be tightly inserted into the corresponding limiting groove.
[0013] In summary, this utility model has the following beneficial effects:
[0014] 1. By setting a pair of outwardly expanding locking plates at both ends of the locking body, the expanded locking plates can form a limit with the locking nut, effectively reducing the risk of the locking nut loosening, thereby improving locking stability and thus improving the binding stability of the reinforcing bars.
[0015] 2. By leveraging the unidirectional limiting capabilities of the locking ratchet ring and the limiting ratchet ring, the risk of the locking nut loosening is further reduced, thereby improving the stability of the reinforcing bar connection components. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Reference Figure 1 A steel bar connection component includes a locking body 1, a locking washer 2, and two locking nuts 3. The locking body 1 is U-shaped, with both ends of the locking body 1 passing through the locking washer 2, and the two locking nuts 3 are threaded onto the corresponding ends of the locking body 1.
[0022] Reference Figure 2 , Figure 3The two ends of the locking body 1 are integrally formed with a pair of arc-shaped locking pieces 4. The concave surfaces of each pair of locking pieces 4 are arranged opposite each other. At the same time, the locking pieces 4 can be pushed outward under the action of external tools and abut against the end of the locking nut 3 away from the locking washer 2 for limiting.
[0023] After the locking nut 3 is tightened, the locking piece 4 can be bent by an external tool so that the locking piece 4 is pushed outward and forms a stop with the locking nut 3, which effectively reduces the risk of the locking nut 3 loosening, improves locking stability, and thus improves the binding stability of the reinforcing bar.
[0024] Reference Figure 2 , Figure 3 Each locking nut 3 has a limiting inclined surface 5 at the end away from the locking washer 2, which allows the corresponding locking piece 4 to abut against it, thereby improving the abutment and limiting effect between the locking nut 3 and the locking piece 4. A guide groove 6 is provided at the connection position between the locking piece 4 and the locking body 1, so that the locking piece 4 can smoothly expand outward along the corresponding guide groove 6. At the same time, each pair of locking pieces 4 has a guide inclined surface 7 on the side away from each other, so that the locking nut 3 can smoothly fit onto the corresponding end of the locking body 1.
[0025] Reference Figure 2 , Figure 3 The locking washer 2 is provided with two elastic locking ratchet rings 8, and each locking nut 3 is fixedly connected with a limiting ratchet ring 9. The limiting helical ring can engage with the corresponding locking ratchet ring 8 to restrict the locking nut 3 from rotating in the direction of loosening, thereby further reducing the risk of the locking nut 3 loosening.
[0026] Reference Figure 2 , Figure 3 Each locking ratchet ring 8 is fixedly connected to a set of limiting posts 10, and the locking pad 2 is provided with two sets of limiting grooves 11. Each set of limiting posts 10 can be tightly inserted into the corresponding limiting groove 11. Since the locking ratchet ring 8 can be disassembled, the staff can choose whether to install the locking ratchet ring 8 according to actual needs.
[0027] The usage process of this embodiment is as follows:
[0028] If the rebar connection component needs to be disassembled later, remove the locking ratchet ring 8, and after the locking body 1 mates with the rebar, tighten the two locking nuts 3 respectively, without needing to pry open the locking plate 4. If the rebar connection component does not need to be disassembled later, install the locking ratchet ring 8, and after the locking body 1 mates with the rebar, tighten the two locking nuts 3 respectively. Then, use an external tool to pry open the locking plate 4.
[0029] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
