Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] As shown in the figure, a mechanical brake structure includes a base 1 and a brake assembly installed on the base 1. The brake assembly includes a brake disc 2, a brake lever 3, a tension spring 4, a cable assembly, a micro switch 8 and other main components. , the brake disc 2 is circular, installed in the circular groove 1.1 in the middle of the right side of the base 1, and connected with the rotor of the motor; the inner side of the brake lever 3 is equipped with a brake pad 3.1, which is on the lower left outside the circular groove 1.1 There is a connecting column 1.2 on the side, and a limiting column 1.3 is provided on the upper left. The lower end of the brake lever 3 is provided with a connecting hole 3.2 that matches the connecting column 1.2, and the upper end is provided with a bending portion that matches the limiting colum...

Abstract

A mechanical brake structure comprises a base and a brake assembly installed on the base. The mechanical brake structure is characterized in that the brake assembly comprises a round brake disc, a brake lever and a micro switch. The round brake disc is connected with a rotor of a motor. The brake lever is provided with a brake block and rotatably arranged on the outer side of the brake disc in a limiting mode, the lower end of the brake lever is arranged on the base in a rotatable mode, the outer side of the upper end of the brake lever is connected with an inhaul cable assembly, the inner side of the upper end of the brake lever is connected with a tension spring, the tension spring enables the brake lever to rotate inwards all the time, and therefore the trend that the brake block and the brake disc are tightly attached is formed. The micro switch is arranged on the outer side of the brake lever, when the inhaul cable is pulled, and the brake lever rotates outwards, the brake block on the inner side of the brake lever is separated from the brake disc, the outer wall of the brake lever abuts against the micro switch, and a power source is connected, so that the motor works. The mechanical brake structure is simple in structure, clear in principle, reliable in brake function and capable of being widely applied to gardening tools including an electric hoe and others and meets the European Union requirement for braking within two seconds.

Description

technical field [0001] The invention belongs to the technical field of garden tools, in particular to a mechanical brake structure suitable for electric hoes and garden tools. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the greening level of living and living, and the large-scale ecological green spaces, residential green spaces, and road green spaces in cities continue to increase. Therefore, various garden tools are also continuously introduced. The defects of the mechanical brake mechanism of the tool are: the brake is invalid; the switch trigger is laborious to operate; and the volume is large. The existing Chinese patent No. CN201210002790.8 "A mechanical brake structure for pruning shears" includes a brake lever, the lower end of the brake lever is linked with the brake device, and the lower part of the brake lever is provided with a brake lever return spring. The upper end of the brake lever i...
