Abstract

The utility model relates to a mechanical door bell, which belongs to life goods doorbell class. The inner side of a door leaf is fixed with a bottom plate on which a roll shaft and a rope roll are arranged, a roll is wound with a pull rope, the shaft is provided with a torsion spring, and the upper end of the roll shaft is provided with a rotation arm on which a ratchet pawl is arranged. A wound spring shaft, an intermediate shaft and an output shaft are arranged between two supporting plates of the bottom plate. The wound spring shaft and the roll shaft are concentric, the shaft is provided with a wound spring and a gear, and the lower end of the shaft is provided with a ratchet wheel. The intermediate shaft is provided with a duplicate gear. The output shaft is provided with the gear and the ratchet wheel, an extending end of the output shaft is provided with a spring and a drive, the bottom plate is fixed with a bell dome, the side of the ratchet wheel of the output shaft is provided with the ratchet pawl, wherein, the outer end of which is hinged with a push rod. When a door is opened, the wound spring stores energy; when the push rod is pushed, the wound spring releases the energy to strike the door bell.

Description

The mechanical type doorbell

The utility model belongs to daily necessities doorbell class.

Existing doorbell all is electronic, be by dry cell or alternating current as the energy, make doorbell or buzzer sounding; This class doorbell need be used electric energy, and economic effect is good inadequately.

The purpose of this utility model is: energy that a kind of utilization the opens the door mechanical type doorbell as the power resources of doorbell is provided.

The technical solution of the utility model is: adopt a base plate that is fixed on the door leaf inboard; On two protruding bearings of base plate, a roll shaft and line roller are housed, are wound with stay cord on the line roller, a torsion spring is housed on the roll shaft, the roll shaft up extension end is fixed with a pivoted arm, rotate the outside ratchet is housed, little torsion spring is housed on the ratchet, be fixed with a sheet of a supporting ratchet outer end on the base plate; Base plate on roll shaft top has two protruding support plates, between two support plates disc spring axle, intermediate shaft, output shaft is housed; The disc spring axle is concentric with roll shaft, on the axle disc spring and gear is housed, and the lower extending end of axle is equipped with ratchet; Duplicate gear is housed on the intermediate shaft; A gear and a ratchet are housed on the output shaft, and the output shaft overhanging end is equipped with spring and batting, and the base plate 1 of batting outside is fixed with a bell dome; On the base plate boss of output dog end side ratchet is housed, the ratchet outer end is hinged with push rod.

Doorbell of the present utility model is to utilize the mechanical energy when opening the door to be stored in the disc spring, promotes the rotation of push rod dish bullet driving shaft and hits the jingle bell bowl, and the good effect of saving the energy is arranged.

Fig. 1 is a structural representation of the present utility model.

Fig. 2, Fig. 3 are partial schematic diagrams.

21 is the base plates that are fixed on the door leaf inboard among the figure, a roll shaft 6 and rope roller 3 are housed on two protruding bearings 1 and 5 of base plate, be wound with stay cord 2 on the rope roller 3, a torsion spring 4 is housed on the roll shaft 6, the up extension end of roll shaft 6 is fixed with a pivoted arm 7, a ratchet 15 is equipped with in pivoted arm 7 outsides, is fixed with the pillar 17 of supporting ratchet 15 outer ends on the base plate.Sabot bullet axle 10 between two protruding

support plates

9 and 12, two support plates, intermediate shaft 13, output shaft 16 are being arranged on the base plate on roll shaft 6 tops; Disc spring axle 10 is concentric with roll shaft 6, on the axle 10 disc spring 11 and gear Z1 is housed, and the lower extending end of axle 10 is equipped with ratchet 8.Duplicate gear Z2 and Z3 are housed on the intermediate shaft 13.A gear Z4 and a ratchet 14 are housed on the output shaft 16; Output shaft 16 overhanging ends are equipped with spring and batting 22, are fixed with a bell dome 18 on the base plate 21 of 22 outsides of batting.On the base plate boss 20 of output dog end 14 sides ratchet 19 is housed, ratchet 19 outer ends are hinged with push rod 25, and 24 is door leafs among the figure, and the 23rd, the cover cap above the base plate 21.The course of work of this doorbell is: when opening the door, the stay cord 2 that an end is fixed on the doorframe rotates rope roller 3, roll shaft 6, pivoted arm 7 and ratchet 15 together, and ratchet 15 combines with ratchet 8 under the work of little torsion spring, makes ratchet 8, disc spring axle 10 rotate disc spring 11 storage power; When shutting door leaf, at the effect lower roller shaft 6 revolution returns of torsion spring 4, the ratchet 15 on the pivoted arm 7 is propped with ratchet 8 disengagings by a sheet 17 and is combined; Under the locking effect of ratchet on the output shaft 16 14 and ratchet 19, the energy storage of disc spring 11 is different to be discharged, only when promoting push rod 25 outdoors ratchet 20 broken away from ratchet 14, the energy storage of disc spring 11 makes gear Z1, Z2, Z3, Z4 and output shaft 16 high-speed rotation, and spring and batting 22 are got rid of under centrifugal action trips out the bowl 18 of ringing a bell.Doorbell of the present utility model without electric energy, utilizes the energy when opening the door to make disc spring 11 energy storage, utilizes this energy storage to fire doorbell, and the characteristics of saving electric energy are arranged.
