A backpack power supply device for hand-held tools

Abstract

The invention relates to a backpack power supply device for a hand-held tool, comprising a backpack body, the backpack body includes a rigid frame, a strap and a waist belt, the straps and the waist belt are respectively connected to the rigid frame, and the rigid frame includes a top cover and a frame body And the bottom bracket, the frame body is provided with a quick locking device, the bottom bracket is provided with a battery pack, the battery pack is connected to the rigid frame through the quick locking device, and the rigid frame is provided with a mesh breathable cloth. The advantages of the present invention are: through The quick locking device fixes the battery pack on the rigid frame stably and reliably, preventing the battery pack from slipping out and hurting people when bending over or in other postures; the part of the rigid frame back that is in contact with the human body is made of mesh breathable cloth, which is breathable and comfortable Hurt the human body; use soft and strong straps and belts to carry the battery pack on the human body without increasing the weight of the two hands, making it easier and more convenient.

Description

technical field [0001] The invention relates to the technical field of power supply devices, in particular to a power supply device for hand-held electric tools or garden tools. Background technique [0002] Existing electric tools or garden tools are generally divided into two types: AC and DC. Communication tools are limited by the power cord when in use, which is inconvenient. The battery pack of DC tools is generally assembled on the machine, which is more convenient to use, but its single use time will be limited by the battery capacity. If you use a large-capacity battery, assemble it on a hand-held tool, because the weight of the tool itself has a great impact on the labor intensity of the operator. If the weight of the tool is not balanced, the operation must apply extra force to keep the tool in balance to proceed smoothly. Therefore, if a power supply such as a battery pack is installed on the tool, the weight of the whole machine will be relatively heavy, and th...

The battery pack of DC tools is generally assembled on the machine, which is more convenient to use, but its single use time will be limited by the battery capacity

If you use a large-capacity battery, assemble it on a hand-held tool, because the weight of the tool itself has a great impact on the labor intensity of the operator. If the weight of the tool is not balanced, the operation must apply extra force to keep the tool in balance to proceed smoothly. Therefore, if a power supply such as a battery pack is installed on the tool, the weight of the whole machine will be relatively heavy, and the labor intensity will be relatively large during use, which will easily make the operator feel tired

[0003] There are also many backpack-type power structures on the market, but most of their backpacks are in the form of soft backpacks. The battery pack is easy to shake freely in the soft backpack, and it is easy to slip out and hurt the staff, which greatly reduces the power of the backpack. The safety performance and ease of use of the traditional power supply
