Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1 to 3. Door closer accent power device, including organism 1, mounting 2, driving piece 3, bearing 4, first bevel gear 5 and second bevel gear 6, be equipped with adjusting screw 7 in the organism 1, the one end at adjusting screw 7 is established to first bevel gear 5 cover, and be located one side of organism 1, the cover is equipped with the nut on adjusting screw 7, the nut is located organism 1, second bevel gear 6 meshes with first bevel gear 5 mutually, the up end of organism 1 is located to mounting 2, the one end of mounting 2 is equipped with mounting hole 21, the bearing 4 cover is established in mounting hole 21, a pot head of driving piece 3 is established in bearing 4, another pot head is established on second bevel gear 6. In the actual use process, the nut on the adjusting screw 7 is abutted to the spring in the machine body 1, and the nut can be driven to move through the rotation of the adjusting screw 7, so that the compression degree of the spring by the adjusting nut is adjusted.

The utility model discloses a door closer accent power device is when the equipment, and first bevel gear 5 and second bevel gear 6 all are located organism 1's the outside. When the door closing force of the door closer needs to be adjusted, an external force acts on the driving piece 3, the driving piece 3 rotates to drive the second bevel gear 6 to rotate, the second bevel gear 6 drives the first bevel gear 5 meshed with the second bevel gear to rotate, and the first bevel gear 5 drives the adjusting screw 7 to rotate together, so that the nut on the adjusting screw 7 is driven to move, and the compression amount of the spring in the machine body 1 is adjusted. When the nut moves towards one side of the spring, the compression amount of the spring is increased, so that the rebound force of the spring during rebounding is increased, and the door closing force of the door closer is increased; on the contrary, when the nut moves to the side far away from the spring, the door closing force of the door closer is reduced. Therefore, the force adjusting device of the door closer can meet different use requirements, and is convenient to adjust. Specifically, when driving piece 3 clockwise rotated, drive first bevel gear 5 and rotate, first bevel gear 5 drove second bevel gear 6 and rotates, and second bevel gear 6 drove adjusting screw 7 and rotates, and adjusting screw 7 drove the nut and walks to compression spring one side, played compression spring's effect, increased the dynamics of closing the door. On the contrary, the compression amount of the spring by the nut is reduced, the door closing force is reduced, the door closer of one model can meet different force using requirements, and the door closer is suitable for selecting light and heavy door leaves.

Meanwhile, the bearing 4 is arranged, so that the driving piece 3 can be conveniently driven to rotate by external force, the external force consumed during rotation is reduced, and the operation is easy; meanwhile, the friction force between the driving piece 3 and the fixing piece 2 is reduced, and the service lives of the driving piece and the fixing piece are prolonged.

The driving member 3 includes a first connector 31, a supporting portion 32 and a second connector 33, the first connector 31 and the second connector 33 are respectively located at the upper end and the lower end of the supporting portion 32, the first connector 31 is sleeved on the bearing 4, the second connector 33 is sleeved on the second bevel gear 6, and the outer diameter of the supporting portion 32 is larger than the outer diameters of the first connector 31 and the second connector 33. Wherein, the driving member 3 is an integrally formed structure, and the second bevel gear 6 is effectively prevented from directly contacting the fixing member 2 by the supporting portion 32.

The outer periphery of the first connector 31 is circular; the periphery of the second connector 33 is hexagonal, so that the second connector 33 can be conveniently fixed, and the driving part 3 can rotate to drive the second bevel gear 6 to rotate together; the first connector 31 is provided with a hexagonal hole 311. Therefore, the hexagonal hole 311 is arranged, so that an external tool can act on the driving piece 3 conveniently, the driving piece 3 can be driven to rotate by external force conveniently, and the operation is convenient.
