[0020] like Figures 1 to 6As shown, in this embodiment, the utility model includes a narrow slide rail 1 fixed to the door frame, and a connecting rod slider 2 connected to the door body is arranged in the narrow slide rail 1. A fixed block 3, a fixed pressure plate 4 and a dynamic pressure plate 5 are also arranged in the narrow slide rail 1. The fixed block 3 is locked and fixed in the narrow slide rail 1 by a locking member 6. One end of the fixed pressure plate 4 is connected to the fixed block 3, and the other end of the fixed pressure plate 4 is provided with a protrusion 7 adapted to the connecting rod slider 2. An adjusting through groove 9 is arranged in the middle of the fixed pressure plate 4. The dynamic pressure plate 5 is fixed to the adjusting through groove 9 of the fixed pressure plate 4 by a locking member 8. The force with which the dynamic pressure plate 5 is pressed against the fixed pressure plate 4 is adjusted by adjusting the locking position of the dynamic pressure plate 5. In this design The locking position of the fixing block 3 in the narrow slide rail 1 can be adapted to the needs of different door-stopping angles. Because the position of the fixing block 3 can be adjusted to adjust the position of the protruding piece 7 in the narrow slide rail 1, the door-stopping position of the connecting rod slider 2 can be adjusted, so that the door body can be at different door-stopping angles. In addition, the dynamic pressure plate 5 can be adjusted to extend and retract forward and backward. The longer the extension distance, the greater the clamping force, and the greater the force required for the connecting rod slider 2 to push up the protruding piece 7 and pass through. Therefore, the utility model can be adapted to the needs of different door-stopping forces. The upper and lower double pressure plate design of the fixed pressure plate 4 and the dynamic pressure plate 5 can provide an adjustable door-stopping force in the range of 15-40N.m, which meets the door-stopping requirements of EN-6 door closers.

[0021] In this embodiment, a concave groove 10 is provided at the upper end of the connecting rod slider 2, and a concave groove 2 11 is provided at the upper end of the fixed block 3. The widths of the concave groove 10, the concave groove 2 11, the fixed pressure plate 4 and the dynamic pressure plate 5 are adapted to each other.

[0022] In this embodiment, an arcuate surface 12 is provided at one end of the protruding piece 7, and a slope surface 13 is provided at the other end of the protruding piece 7. Both ends of the concave slide groove 10 are provided with inclined table surfaces 14 that are compatible with the arcuate surface 12 or the slope surface 13 of the protruding piece 7. This design facilitates the connecting rod slider 2 to smoothly push the protruding piece 7 upward and enable the connecting rod slider 2 to smoothly pass through the protruding piece 7.

[0023] In this embodiment, the locking member 6 is a set screw, and one end of the fixing block 3 is fixed in the narrow slide rail 1 through the set screw.

[0024] In this embodiment, one end of the fixed pressure plate 4 is fixed to the fixed block 3 by a bolt 41, and a fixed hole 15 is provided at one end of the fixed pressure plate 4. One end of the bolt 41 is fixed to the lower end of the fixed block 3, and the other end of the bolt 41 passes through the fixed block 3 and is fixed in the fixed hole 15.

[0025] In this embodiment, a mounting hole 16 is provided in the middle of the dynamic pressure plate 5, and the locking member 8 is a screw. The dynamic pressure plate 5 is fixed in the mounting hole 16 after the screw passes through the adjusting slot 9. This design can determine the extension distance of the dynamic pressure plate 5 by adjusting the position of the screw installed in the adjusting slot 9.

[0026] In this embodiment, the cross-sectional area of ​​the narrow slide rail 1 is 19.7*12 mm, which is convenient for installation in a profile door.

[0027] In this embodiment, one end of the concave slide groove 10 is provided with an avoidance limit groove 17 adapted to the screw nut part, and the inclined table surface 14 at one end of the concave slide groove 10 is located on both sides of the avoidance limit groove 17.

[0028] In this embodiment, one end of the dynamic pressure plate 5 is provided with an avoidance notch 18 adapted to the stud portion of the bolt 41 .

[0029] In this embodiment, the working process of the utility model is as follows: when the connecting rod slider 2 slides on the narrow slide rail 1, it passes through the protruding piece 7 of the fixed pressure piece 4 to make the connecting rod slider 2 stay under the fixed pressure piece 4. At this time, the door body is in a door-stopping state. By pushing the door in the closing direction, the connecting rod slider 2 pushes up the protruding piece 7, so that it can move out from under the fixed pressure piece 4, and the door closer closes the door body. The door-stopping positioning function of the door closer is realized through this system of positioning block + pressure piece + connecting rod slider.

[0030] The utility model is applied to the technical field of door closers.

[0031] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
