[0026] Specifically, the rocker body 201 is made of plastic, which eliminates the need for the traditional aluminum rocker body 201 and reduces costs.

[0027] In one embodiment, the inner wall of the door closer housing 101 is movably connected to the outer wall of the rocker body 201. One side of the inner wall of the rocker body 201 is rotatably connected to the outer wall of the rotating block 202 via a pivot. One side of the rotating block 202 is fixedly connected to one side of the bullet block 203. The top of the bullet block 203 is movably connected to the inner wall of the locking groove. A positioning block is provided on the side of the rocker body 201 away from the rotating block 202, and the outer wall of the positioning block is movably connected to the inner wall of the slot 106. A fixing groove 204 is provided at the bottom of the rocker body 201, and a limiting groove 205 is provided on the inner wall of the fixing groove 204. A through groove 206 is provided at the top of the fixing groove 204, and the top of the rocker body 201 is fixedly connected to the bottom of the fixing ring piece 207. The fixing ring piece 207 is located at the top of the through groove 206.

[0028] Specifically: When it is necessary to disassemble and replace the rocker body 201, push the blocking block 308 so that the blocking block 308 enters the spring groove 306 and at the same time squeezes the return spring 307 so that the blocking block 308 does not block the fixed ring piece 207, thereby disassembling the rocker body 201, which facilitates the disassembly and replacement of the rocker body 201.

[0029] In one embodiment, the inner bottom wall of the door closer housing 101 is fixedly connected to the bottom of the support block 301, the bottom of the support block 301 is fixedly connected to the top of the connecting spring 302, the top of the connecting spring 302 is fixedly connected to the bottom of the mounting block 303, the outer wall of the mounting block 303 is fixedly connected to the inner side of the limiting block 304, the outer wall of the mounting block 303 is movably connected to the inner wall of the fixing groove 204, the inner wall of the limiting block 304 is movably connected to the outer wall of the limiting groove 205, the top of the mounting block 303 is fixedly connected to the bottom of the extension rod 305, and the outer wall of the extension rod 305 is movably connected to the inner wall of the through groove 206.

[0030] Specifically: the mounting block 303 and the extension rod 305 enter the interior of the fixing groove 204 and the through groove 206 respectively, while the limiting block 304 enters the interior of the limiting groove 205 for initial stabilization. The installation block 303, the limiting block 304 and the extension rod 305 increase the support effect on the rocker body 201.

[0031] In one embodiment, the bottom of the extension rod 305 is provided with a spring groove 306, and the inner wall of the spring groove 306 is fixedly connected to one end of the return spring 307, the other end of the return spring 307 is fixedly connected to one side of the blocking block 308, and the outer wall of the blocking block 308 is movably connected to the inner wall of the spring groove 306.

[0032] Specifically: the reset spring 307 drives the blocking block 308 to block the top of the fixed ring plate 207, thus ensuring the stability of the rocker body 201.

[0033] Working principle: The positioning card 104 is initially in a flat position, while the end of the rocker body 201 near the positioning card 104 is tilted up. Simultaneously, the spring block 203 is located below the slider 107. The electromagnet 102 is activated, causing the locking block 103 to move inwards into the slide groove 105. As the locking block 103 continues to move, it causes the positioning card 104 to rotate, thus pressing the positioning block inside the slot 106. This causes the end of the rocker body 201 near the spring block 203 to tilt up, locking the spring block 203 against the slider 107. When the rocker body 201 needs to be disassembled and replaced, the blocking block 308 is pushed, causing it to enter the spring groove 306, simultaneously pressing the return spring 307. The stop block 308 does not obstruct the fixed ring piece 207, thereby disassembling the rocker body 201 and placing the new rocker body 201 into the door closer housing 101 to complete the alignment of the two ends. At the same time, the mounting block 303 and the extension rod 305 enter the fixed groove 204 and the through groove 206 respectively, and the limiting block 304 enters the limiting groove 205 for initial stabilization. When the extension rod 305 enters the through groove 206, the inner wall of the through groove 206 presses the arc-shaped surface of the stop block 308, causing the stop block 308 to enter the spring groove 306. When the stop block 308 is above the fixed ring piece 207, the reset spring 307 causes the stop block 308 to be blocked at the top of the fixed ring piece 207.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
