Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a door closer with a lubrication structure. The door closer body 01 and the torsion spring 26 used in this application are both products that can be directly purchased on the market, and their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here.

[0025] It includes: a door closer body 01, a lubrication assembly 02 is arranged above the door closer body 01, and an adjustment assembly 03 is arranged on one side of the door closer body 01;

[0026] The lubrication assembly 02 includes an oil box 21, a box plug 22 is plugged on one side of the oil box 21, fixed rods 23 are fixedly arranged inside both sides of the oil box 21, a rotating plate 24 is connected to the outer wall of the fixed rod 23, a rubber plate 25 is fixedly arranged inside the lower part of the rotating plate 24. When the rubber plate 25 rotates away, the lubricant will flow out through the holes. A torsion spring 26 is arranged around the fixed rod 23, and the torsion spring 26 provides elastic force. Under the action of the elastic force of the torsion spring 26, the rotating plate 24 can return to the initial position, and the rubber plate 25 blocks the holes of the oil box 21 to prevent the lubricant in the oil box 21 from flowing out continuously.

[0027] Further, the adjustment assembly 03 includes a fixing plate 31, the fixing plate 31 plays a guiding role for the toothed plate 36. A shaft rod 32 penetrates through one end of the fixing plate 31. When the shaft rod 32 rotates, it can drive the gear 35 to rotate. The rotation of the gear 35 can drive the toothed plate 36 to move, thereby adjusting the length. A rocker 33 is fixedly connected above the shaft rod 32. A bolt 34 penetrates through one end of the rocker 33 away from the shaft rod 32. The bolt 34 can be screwed into the fixing plate 31 through the hole of the rocker 33 to limit the rocker 33. A gear 35 is connected to the outer wall of the shaft rod 32, and the outer wall of the gear 35 meshes with the toothed plate 36.

[0028] Further, the oil box 21 is fixedly connected to the door closer body 01 to ensure the firmness of the position of the oil box 21. The rotating plate 24 is rotatably connected to the fixed rod 23 to ensure that the fixed rod 23 does not affect the rotation of the rotating plate 24. The rotation of the rotating plate 24 can drive the rubber plate 25 to rotate, and the rubber plate 25 plays a role in enhancing the seal.

[0029] Furthermore, the oil box 21 is provided with a hole corresponding to the rubber plate 25. When the rubber plate 25 rotates away, the lubricant will flow out through the hole. The two ends of the torsion spring 26 are fixedly connected to the oil box 21 and the rotating plate 24 respectively. The torsion spring 26 provides elastic force. Under the action of the elastic force of the torsion spring 26, the rotating plate 24 can return to the initial position, and the rubber plate 25 blocks the hole of the oil box 21 to prevent the lubricant in the oil box 21 from flowing out continuously.

[0030] Furthermore, one end of the fixing plate 31 far away from the shaft rod 32 is rotationally connected to the rotating shaft of the door closer main body 01.

[0031] Furthermore, the shaft rod 32 is rotationally connected to the fixing plate 31 to ensure that the fixing plate 31 does not affect the rotation of the shaft rod 32. The rotation of the shaft rod 32 can drive the gear 35 to rotate. The bolt 34 is threadedly connected to the fixing plate 31, and the bolt 34 can be passed through the hole of the rocker 33 and screwed into the fixing plate 31 to limit the rocker 33.

[0032] Furthermore, the gear 35 is fixedly connected to the shaft rod 32 to ensure that the rotation of the shaft rod 32 can drive the gear 35 to rotate. The rotation of the gear 35 can drive the rack 36 to move, thereby adjusting the length. The rack 36 is slidably connected to the fixing plate 31, and the fixing plate 31 plays a guiding role for the rack 36.

[0033] Working principle: When in use, first install one end of the door closer main body 01 on the door body. According to the actual size, unscrew the bolt 34, rotate the rocker 33, the rocker 33 drives the shaft rod 32 to rotate, the shaft rod 32 drives the gear 35 to rotate, the gear 35 drives the rack 36 to move, thereby adjusting the length. Then pass the bolt 34 through the hole of the rocker 33 and screw it into the fixing plate 31 to limit the rocker 33. When the rotating rod of the door closer main body 01 starts to rotate subsequently, the rotating rod of the door closer main body 01 will push the rotating plate 24 to rotate. The rotating plate 24 drives the rubber plate 25 to rotate. The rubber plate 25 does not block the hole of the oil box 21, and the lubricant in the oil box 21 will flow into the rotating shaft of the door closer main body 01. When the rotating rod of the door closer main body 01 rotates away, under the action of the elastic force of the torsion spring 26, the rotating plate 24 returns to the initial position, and the rubber plate 25 blocks the hole of the oil box 21 again, completing one addition of the lubricant. The above is the entire working principle of the present utility model.
