Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example I

Referring to fig. 1-5, a high-strength door closer installing support comprises a door frame 1, wherein a door plate 11 is hinged to the door frame 1 through a door hinge, a first bearing 12 is installed on the door frame 1, a shaft lever 13 is in interference fit with the first bearing 12, a second bearing 14 is in interference fit with the lower end of the shaft lever 13, a cylinder 15 is rotatably installed on the second bearing 14, a connecting rod 16 is slidably sleeved in the cylinder 15, and a connecting block 17 in butt joint with the door plate 11 is fixed on the connecting rod 16.

Further, a supporting rod 18 is fixed on the second bearing 14, and a rotating seat 19 fixed on the cylinder 15 is in interference fit with the supporting rod 18 in a rotating manner, so that the curved rod motion of a triangular structure can be realized, and the door plate 11 can be normally opened and closed.

Further, the base 2 is welded on the first bearing 12, the base 2 is tightly attached to the door frame 1, and the base 2 can realize the connection and fixation of the first bearing 12 and the door frame 1, so that the first bearing and the door frame 1 are used as a good and stable support structure.

Further, the base 2 is fixedly connected with the door frame 1 through the first bolts 21, the number of the first bolts 21 is two, the first threaded holes corresponding to the first bolts 21 are symmetrically distributed, the base 2 is provided with the first threaded holes corresponding to the first bolts 21, the door frame 1 is provided with the first thread grooves corresponding to the first bolts 21, and the first bolts 21 are in mutual threaded butt joint with the first threaded holes and the first thread grooves.

Further, the second bolt 3 is arranged on the connecting block 17 in a threaded manner, the second bolt 3 is in threaded butt joint with the door plate 11, a second threaded hole corresponding to the second bolt 3 is arranged on the connecting block 17, a second threaded groove corresponding to the second bolt 3 is arranged on the door plate 11, and the second bolt 3 is in threaded butt joint with the second threaded hole and the second threaded groove respectively.

Further, the spring 4 is fixed in the cylinder 15, the other end of the spring 4 is fixedly connected with the connecting rod 16, the spring 4 is in a balanced state, the door plate 11 and the door frame 1 are guaranteed to be closed and reset stably, after the door plate 11 is opened, the spring 4 stretches, and when the force applied to the door plate 11 disappears, the spring 4 achieves the closing of the door plate 11 and the door frame 1 through a reset effect.
