[0004] The above-mentioned prior art is to fix the conical connecting sleeve by squeezing it on both sides. However, when the cylindrical connecting sleeve is used to connect two groups of steel bars, one end of the connecting sleeve is first screwed into the connecting end of one group of steel bars, and then the connecting end of the other group of steel bars is screwed into the other end of the connecting sleeve for fixation. However, when the other group of steel bars is screwed into the other end of the connecting sleeve, it is necessary to use a clamp to squeeze the connecting sleeve to prevent the connecting sleeve from being rotated due to force when the other group of steel bars is screwed in, thereby causing the connecting sleeve and the first group of steel bars to loosen or rotate excessively. However, when clamping and squeezing is performed by means of a clamp, a worker is required to continue squeezing manually while another person screws the other group of steel bars for connection, which makes the use of the steel bar connecting sleeve squeezing device more inconvenient.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 - Figure 5 As shown, the utility model provides a technical solution: a steel bar connection sleeve extrusion device, including a fixed sleeve 1, threaded joints 11 are meshed inside the two ends of the fixed sleeve 1, and the end of the threaded joint 11 away from the fixed sleeve 1 is fixedly connected to a steel bar 12, a pushing component is arranged on the outside of one end of the fixed sleeve 1, and an extrusion component is arranged on the end of the pushing component close to the fixed sleeve 1, a buffer component is fixedly connected to the end of the extrusion component close to the pushing component, and a positioning component is rotatably connected to the middle end of the pushing component, and an anti-slip component is fixedly connected to the inner side of the end of the positioning component close to the fixed sleeve 1. When in use First, the pushing component drives the extrusion component to fit the fixed sleeve 1, and then the pushing component is extruded to compress the buffer component through the extrusion component, and then the clamping components at both ends are moved to make the clamping component drive the anti-slip component to clamp the fixed sleeve 1, and then the pushing component is started, and the pushing component is allowed to apply pressure to the extrusion component with the assistance of the clamping component, so that the extrusion component and the clamping component can limit the extrusion of the fixed sleeve 1, which can quickly complete the extrusion limitation of the connecting sleeve, so that the worker does not need to hold the squeeze, thereby realizing single-person operation and improving the convenience of using the extrusion device.

[0022] like Figure 2As shown, the pushing assembly includes a shell 2 arranged on the outside of one end of the fixed sleeve 1, and the two ends of the shell 2 are fixedly connected to the inside with an electric telescopic rod 21. When the electric telescopic rod 21 is started, the electric telescopic rod 21 extends and squeezes the squeezing assembly with the assistance of the buffer assembly.

[0023] like Figure 4 As shown, the extrusion assembly includes a push plate 3 arranged on the outer side of one end of the electric telescopic rod 21 away from the shell 2, and the end of the push plate 3 close to the electric telescopic rod 21 is fixedly connected to the electric telescopic rod 21. The shell 2 drives the push plate 3 to fit with the fixed sleeve 1 and the first group of steel bars 12, so as to facilitate the use of the fit between the push rod 31 and the fixed sleeve 1, thereby cooperating with the positioning assembly to limit the positioning of the fixed sleeve 1.

[0024] like Figure 4 As shown, the buffer assembly includes an insertion rod 4 fixedly connected to one end of the electric telescopic rod 21 near the electric telescopic rod 21, and the end of the insertion rod 4 away from the push rod 31 is inserted in the electric telescopic rod 21, and the end of the insertion rod 4 inserted in the electric telescopic rod 21 is fixedly connected with a spring 41, and the end of the spring 41 away from the insertion rod 4 is fixedly connected to the electric telescopic rod 21. After the electric telescopic rod 21 is started, it extends and continues to compress the spring 41 under the limit of the insertion rod 4, so that the push plate 3 and the push rod 31 are squeezed by means of the insertion rod 4 and the spring 41, which is convenient for providing power to the squeezing assembly, thereby limiting the fixed sleeve 1 through the cooperation of the squeezing assembly and the positioning assembly.

[0025] like Figure 3 As shown, the locking assembly includes a rotating plate 5 rotatably connected to both sides of the middle end of the shell 2, and a snap ring 51 is fixedly connected to the end of the rotating plate 5 away from the shell 2, and the inner side of the snap ring 51 is sleeved on the outer side of the fixed sleeve 1. The two groups of rotating plates 5 are moved so that the rotating plates 5 drive the snap ring 51 to be sleeved on the outer side of the fixed sleeve 1, so that the two groups of rotating plates 5 and the snap ring 51 are engaged with the fixed sleeve 1 to realize the restriction between the fixed sleeve 1 and the push plate 3.

[0027] Working principle: When the fixed sleeve 1 is used to connect the two sets of threaded joints 11 and the steel bar 12, one end of the fixed sleeve 1 is first screwed into the outside of the threaded joint 11 on the first set of steel bar 12, and then the outer shell 2 drives the push plate 3 to fit with the fixed sleeve 1 and the first set of steel bar 12, and then the outer shell 2 is pressed, so that the outer shell 2 allows the insertion rod 4 to be inserted into the electric telescopic rod 21 with the assistance of the push rods 31 and 32 to compress the spring 41, and then the two sets of rotating plates 5 are moved, so that the rotating plates 5 drive the clamping ring 51 to be sleeved on the outside of the fixed sleeve 1, and the clamping ring 51 synchronously drives the anti-skid pad 6 and the anti-skid strip 61 to rotate when being sleeved. , so that the anti-skid pad 6 and the anti-skid strip 61 fit the fixed sleeve 1, and then start the electric telescopic rod 21. After the electric telescopic rod 21 is started, it extends and continues to compress the spring 41 under the limit of the insertion rod 4, thereby squeezing the push plate 3 and the push rod 31 with the help of the insertion rod 4 and the spring 41, and using the push plate 3 and the clamping ring 51 to make the anti-skid pad 6 and the anti-skid strip 61 fit closely with the fixed sleeve 1 for restriction, and then screw the threaded joint 11 on the second group of steel bars 12 into the other end of the fixed sleeve 1. After the installation is completed, start the electric telescopic rod 21 to shrink the electric telescopic rod 21, and finally open the clamping ring 51 to take out the shell 2, etc.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
