Description

Technical Field

[0001] This utility model relates to the technical field of connectors for precision rolled threaded steel bars, and in particular to a connector for precision rolled threaded steel bars. Background Technology

[0002] During construction, concrete and steel reinforcement are typically combined to improve overall rigidity and make the structure more robust. When connecting steel reinforcement bars during construction, steel wire ropes are generally used to tie the two bars together, or threaded steel bar connectors are used to connect the two bars.

[0003] Both of the above-mentioned steel bar connection methods in the existing technology require the cooperation of more than two workers, which is time-consuming and labor-intensive. Therefore, it is necessary to design a matching connector for precision rolled threaded steel bars that is easy to install and has a stable structure after installation. Utility Model Content

[0004] Therefore, it is necessary to provide a matching connector for precision-rolled threaded steel to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a matching connector for precision rolled threaded steel bars, including a sleeve and several arc-shaped sliding plates. The arc-shaped sliding plates are arranged in a ring at both ends inside the sleeve. The arc-shaped sliding plates are located inside the sleeve, and a telescopic rod is installed on the arc-shaped sliding plate. The telescopic rod is slidably engaged with the sleeve. A spring is installed inside the telescopic rod. Several slots are provided inside the arc-shaped sliding plates. A locking plate is rotatably installed in the slot. The end of the locking plate away from the sleeve inlet deflects and extends out of the slot. A spring is installed in the slot. The output end of the spring is connected to the end of the locking plate located in the slot.

[0006] Preferably, the two ends of the arc-shaped slide plate are respectively provided with a slide groove and a slider, and the slide groove and slider on the adjacent arc-shaped slide plate are slidably engaged.

[0007] Preferably, the card plate is inclined, and the inclination angle of the card plate is adapted to the turning angle of the thread on the rebar.

[0008] Preferably, the sleeve is provided with an extension ring, and the telescopic rod is slidably engaged in the extension ring.

[0009] Preferably, the end of the arc-shaped slide plate near the sleeve inlet is chamfered.

[0010] Preferably, the end of the card plate extending out of the card slot has a chamfer.

[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0012] 1. The reinforcing bar can be directly inserted from one end of the sleeve into several arc-shaped sliding plates inside. After insertion, several inclined clamps on the arc-shaped sliding plates make it difficult for the reinforcing bar to be pulled out, thus facilitating installation.

[0013] 2. By setting the spring inside the telescopic rod, the arc-shaped sliding plate can be set to a smaller size, so that the arc-shaped sliding plate can be pushed open by the steel bar. Under the compression of the spring and the arc-shaped sliding plate, the connection and installation of the steel bar is more stable. Attached Figure Description

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 3 This application provides a connector for precision rolled threaded steel bars, including a sleeve 1 and several arc-shaped sliding plates 2. The arc-shaped sliding plates 2 are arranged in a ring at both ends inside the sleeve 1. The arc-shaped sliding plates 2 are located inside the sleeve 1. A telescopic rod 3 is installed on the arc-shaped sliding plate 2. The telescopic rod 3 is slidably engaged with the sleeve 1. A spring 4 is installed inside the telescopic rod 3. Several slots 5 are provided inside the arc-shaped sliding plate 2. A retaining plate 6 is rotatably installed in the slots 5. The end of the retaining plate 6 away from the inlet of the sleeve 1 deflects and extends out of the slot 5. A spring 7 is installed in the slot 5. The output end of the spring 7 is connected to the end of the retaining plate 6 located in the slot 5.

[0020] In this embodiment, when connecting two threaded steel bars, one end of the threaded steel bar can be directly inserted into the annulus formed by several arc-shaped sliding plates 2 inside the sleeve 1. Since the end of the clamping plate 6 that is deflected away from the inlet of the sleeve 1 extends out of the clamping groove 5, the steel bar will push the clamping plate 6 to deflect during insertion, so that the steel bar can be inserted smoothly. After insertion, the spring 7 that was stretched when the clamping plate 6 deflected will pull the clamping plate 6 back to reset. Thus, the end of the clamping plate 6 that extends out of the clamping groove 5 can abut against the threaded groove on the threaded steel bar. And during abutment, since the clamping plate 6 is deflected and tilted, when the threaded steel bar wants to be pulled out, the tilted clamping plate 6 can abut against and limit it. When the threaded steel bar is inserted, the arc-shaped sliding plates 2 will be squeezed, causing adjacent arc-shaped sliding plates 2 to separate and slide towards the inner wall of the sleeve 1, so that the spring 4 inside the telescopic rod 3 is compressed. Thus, through the compression of the spring 4, the arc-shaped sliding plates 2 can squeeze the threaded steel bar, further improving the stability after installation.

[0021] In some embodiments, to improve the stability of the arc-shaped slide plate 2 when it is squeezed and slid by the threaded steel bar, the arc-shaped slide plate 2 is provided with a groove 8 and a slider 9 at both ends, and the groove 8 on adjacent arc-shaped slide plates 2 is slidably engaged with the slider 9. The groove 8 and the slider 9 can be spaced a certain distance apart so that the arc-shaped slide plate 2 can slide quickly when the threaded steel bar is inserted.

[0022] In some embodiments, to further improve the fixing effect of the clamping plate 6 on the threaded steel bar, the tilt angle of the clamping plate 6 is adapted to the turning angle of the thread on the threaded steel bar. This increases the contact area between the clamping plate 6 and the thread on the threaded steel bar, making it less likely for the threaded steel bar to detach from the sleeve 1.

[0023] In some embodiments, to facilitate the insertion of the telescopic rod 3 into the sleeve 1, an extension ring 10 is provided on the sleeve 1, and the telescopic rod 3 is slidably engaged within the extension ring 10. This allows the wall thickness of the sleeve 1 to be set thinner as needed, saving costs.

[0024] In some embodiments, to facilitate the insertion of the threaded steel bar into the arc-shaped slide plate 2, the end of the arc-shaped slide plate 2 near the inlet of the sleeve 1 is chamfered.

[0025] In some embodiments, to further improve the engagement effect between the clamping plate 6 and the threaded steel bar, a chamfer is provided at one end of the clamping plate 6 extending out of the clamping groove 5. Thus, after the clamping plate 6 is reset and deflected, the bottom surface of the extended end of the clamping plate 6 can fit into the threaded groove of the threaded steel bar, making it less likely for the threaded steel bar to detach from the sleeve 1.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
