[0023] The following combines the attached Figures 1 - 5 To further elaborate on this application,

[0024] An embodiment of this application discloses a cold pressing connector for steel reinforcement cages. Refer to Figure 1 , Figure 2 and Figure 3 , a cold pressing connector for steel reinforcement cages includes a cold press 1. The cold press 1 includes a body 101. A first fixing seat 102 is fixedly connected to the bottom of the inner cavity of the body 101. A second fixing seat 103 is fixedly connected to the top of the inner cavity of the body 101. A support seat 107 is fixedly connected to the top of the first fixing seat 102. A cylinder 104 is fixedly connected to the top of the body 101. The output end of the cylinder 104 is fixedly connected to a push plate 105. The bottom of the push plate 105 is fixedly connected to a movable seat 106. The top of the movable seat 106 is movably connected to the bottom of the second fixing seat 103. Observation mechanisms 2 are installed on both sides of the body 101;

[0025] The observation mechanism 2 includes a moving groove 201 and a scale groove 202. The moving groove 201 is opened on both sides of the inner cavity of the device body 101, and the scale groove 202 is opened at the top and bottom of both sides of the inner cavity of the device body 101. A moving plate 208 is movably connected to the inner cavity of the moving groove 201. A synchronous plate 203 is fixedly connected to the inner side of the moving plate 208. A connecting plate 204 is fixedly connected to the outer side of the moving plate 208. Pointing arrows 205 are fixedly connected to both the top and bottom of the connecting plate 204, and the pointing arrows 205 are used in cooperation with the scale groove 202.

[0026] Referring to Figure 2 , a positioning ring 209 is fixedly connected to the front side of the synchronous plate 203. The diameter of the inner cavity of the positioning ring 209 is larger than the diameter of the inner cavity of the synchronous plate 203. Through the setting of the positioning ring 209, the position of the connecting sleeve is positioned, so that one end of the connecting sleeve can stably fit on the surface of the synchronous plate 203, thereby preventing the connecting sleeve from detaching from the surface of the synchronous plate 203 during the movement process, resulting in a deviation in the pointing position of the pointing arrow 205.

[0027] Referring to Figure 1 and Figure 2 , a guide rod 206 is fixedly connected to the inner cavity of the moving groove 201. The surface of the guide rod 206 is movably connected to the inner cavity of the moving plate 208. Through the setting of the guide rod 206, the movement of the moving plate 208 is guided, improving the stability of the moving plate 208 during the movement process, and preventing the moving plate 208 from detaching from the inside of the moving groove 201 during the movement process, resulting in a deviation in the position of the synchronous plate 203.

[0028] Referring to Figure 1 and Figure 2 , a spring 207 is fixedly connected to the back side of the moving plate 208. The back side of the spring 207 is fixedly connected to the back side of the inner cavity of the moving groove 201. The inner cavity of the spring 207 is sleeved on the surface of the guide rod 206. Through the setting of the spring 207, the position of the moving plate 208 is supported. When the moving plate 208 moves, the spring 207 will be compressed and deformed under force, so that when the connecting sleeve detaches from the surface of the synchronous plate 203, the synchronous plate 203 can be pushed to quickly reset for subsequent continued use.

[0029] Referring to Figure 1 , Figure 4 and Figure 5, a detection mechanism 3 is installed in the inner cavity of the first fixed seat 102. The detection mechanism 3 includes a storage groove 301 which is opened on the front side of the inner cavity of the first fixed seat 102. A support rod 305 is fixedly connected to the inner cavity of the storage groove 301. A detection ring 302 is movably connected to the surface of the support rod 305. Through the arrangement of the support rod 305, the position of the detection ring 302 is supported, so that the detection ring 302 can rotate on the surface of the support rod 305, thereby adjusting the position of the detection ring 302. Thus, after the detection ring 302 is unfolded, the connecting sleeve can slide inside the detection ring 302 to detect whether there are protrusions on the surface of the connecting sleeve, preventing the internal steel bars from being clamped during extrusion due to the uneven surface of the connecting sleeve.

[0030] Refer to Figure 5 , damping rings 303 are movably connected to both the top and bottom of the surface of the detection ring 302. The inner cavity of the damping ring 303 is fixedly connected to the surface of the support rod 305. The damping ring 303 is made of rubber. Through the arrangement of the damping ring 303, the position of the detection ring 302 is limited to prevent the detection ring 302 from moving up and down on the surface of the support rod 305 during rotation. And since the damping ring 303 is made of rubber material, the friction force received by the detection ring 302 during rotation can be increased, thereby further improving the fixing effect after the detection ring 302 is unfolded.

[0031] Refer to Figure 1 and Figure 5 , a positioning seat 304 is fixedly connected to the back side of the inner cavity of the storage groove 301. The inner cavity of the positioning seat 304 is clamped with the surface of the detection ring 302. Through the arrangement of the positioning seat 304, the position of the detection ring 302 is positioned. Thus, after the detection ring 302 is received into the inner part of the storage groove 301, the position of the detection ring 302 can be clamped and fixed to prevent the detection ring 302 from unfolding from the inner part of the storage groove 301 when not in use, thereby playing a protective role for the detection ring 302.

[0032] Working principle: First, the operator rotates by holding the detection ring 302 to remove the detection ring 302 from the inside of the positioning seat 304. During the rotation of the detection ring 302, it will gradually unfold from the inside of the storage groove 301 and move within the inner cavity of the damping ring 303 during the rotation. Thus, the friction force received by the detection ring 302 during rotation is increased through the setting of the damping ring 303 to further improve the fixing effect after the detection ring 302 is fully unfolded. When the detection ring 302 is fully unfolded, the connecting sleeve can be attached to the inner side of the detection ring 302, and the connecting sleeve is held and moved on the inner side of the detection ring 302 to check whether there are protrusions on the surface of the connecting sleeve, preventing the internal steel bars from being pinched during extrusion due to the uneven surface of the connecting sleeve. The steel bar is inserted into the inside of the connecting sleeve, and the connecting sleeve is held and moved. During the movement of the connecting sleeve, it will contact the surface of the synchronous plate 203. The movement of the connecting sleeve pushes the synchronous plate 203 to move, and during the contact between the connecting sleeve and the synchronous plate 203, it will be inserted into the inside of the positioning ring 209. Thus, the connecting sleeve is positioned by the positioning ring 209 to prevent the connecting sleeve from detaching from the surface of the synchronous plate 203 during movement. The movement of the synchronous plate 203 drives the moving plate 208 to move. During the movement of the moving plate 208, it will slide on the surface of the guide rod 206. Thus, the movement of the moving plate 208 is guided by the guide rod 206 to make the movement of the moving plate 208 smoother. At the same time, the moving plate 208 can be prevented from detaching from the inside of the moving groove 201 during movement, and the spring 207 supports the surface of the moving plate 208. During the movement of the moving plate 208, the spring 207 will be compressed and deformed under force. Thus, when the connecting sleeve detaches from the surface of the synchronous plate 203, the synchronous plate 203 can be pushed to quickly reset for subsequent continued use. The movement of the moving plate 208 drives the connecting plate 204 to move, the movement of the connecting plate 204 drives the pointing arrow 205 to move, and by cooperating with the scale groove 202 through the pointing arrow 205, it is convenient to check the current position of the connecting sleeve. When the connecting sleeve reaches the specified position, the cylinder 104 is used to push the push plate 105 to move downward, and the movement of the push plate 105 drives the movable seat 106 to move to squeeze the connecting sleeve on the top of the support seat 107, so that the connecting sleeve is stably fixed on the surface of the steel bar.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
