A kind of knapsack supply unit that is used for hand-held tool
Technical field
The present invention relates to the supply unit technical field, especially a kind of supply unit that is used for hand held electric tool or garden instrument.
Background technology
Existing electric tool or garden instrument generally are divided into two kinds of AC and DCs.Media of communication time in use can be subjected to the restriction of power line, and is inconvenient.The power brick of DC tools generally is assembled on the machine, use more convenient, but the time that its single uses can be subjected to the restriction of battery capacity.If use jumbo battery, be assembled on the handheld tool, because the weight of instrument itself produces very big influence to operator's labour intensity, if it is unbalanced that instrument weight is provided with, operation must apply extra power makes instrument keep balance to operate smoothly, therefore, if when power supplies such as power brick are set on instrument, the weight of complete machine is just heavier, and labour intensity is just bigger when in use, is easy to make the operator to feel tired.
Now also have a lot of Backpack type power supply architectures on the market, but their knapsack adopts soft knapsack form mostly, power brick is arbitrarily rocked easily in soft knapsack the inside, even slide out easily and hurt the staff, this just greatly reduces the security performance and the ease of use of Backpack type power supply.
Summary of the invention

Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
See also Fig. 1 to Fig. 3, a kind of knapsack supply unit that is used for hand-held tool of the present invention comprises knapsack body 1, and described knapsack body 1 comprises rigid frame 2, braces 3 and waistband 4.Described braces 3 is connected with rigid frame 2 respectively with waistband 4, described rigid frame 2 comprises top cover 21, frame body 22 and bottom bracket 23, described frame body 22 is provided with quick-locking device 5, on the described bottom bracket 23 power brick 6 is set, described power brick 6 is connected with rigid frame 2 by quick-locking device 5.
This knapsack supply unit that is used for hand-held tool adopts reliablely and stablely self-contained battery bag 6 of rigid frame 2, thereby prevents that power brick 6 from arbitrarily rocking in soft sack.Quick-locking device 5 is set on the rigid frame 2, and power brick 6 is fixedlyed connected with rigid frame 2 by quick-locking device 5, prevent the people bend over or during other postures power brick 6 skid off and hurt sb.'s feelings.
As shown in Figure 3, braces 3 is connected the left and right sides, the back side of rigid frame 2, and described braces 3 extends to the bottom from the top at rigid frame 2 back sides; Waistband 4 is connected the bottom at rigid frame 2 back sides, and described waistband 4 extends to the bottom other end from bottom one end at the back side of rigid frame 2.
Be used for the knapsack supply unit of hand-held tool at this, power brick 6 is fixed on the rigid frame 2, carries on the back on human body by soft solid braces 3 and waistband 4 again, and is easy and convenient, adopt the mode of carrying on the back not increase the gripping weight of two hands, carry on the back also light relatively at back.
As shown in Figure 1, be provided with power supply lead wire 8 with frame body 22 junctions on the power brick 6, described power brick 6 connects handheld tool by power supply lead wire 8, promptly is electric connection between power brick 6 and the handheld tool.Power brick 6 is supplied with handheld tool by power supply lead wire 8 with electricity, just can reach the purpose of power supply like this under the situation of the gripping weight that does not increase by two hands, and is simple and convenient, can keep enough electric weight again can comparatively light tool using.
As shown in Figure 1, rigid frame 2 is provided with netted ventilative cloth 7, and this netted ventilative cloth 7 contacts with human body in actual use, and promptly the part that contacts with human body on the rigid frame 2 is adopted netted ventilative cloth 7, and is ventilative comfortable, also can not cough up the body of hurting sb.'s feelings simultaneously.
The knapsack supply unit that is used for hand-held tool of the present invention, rigid frame 2 is a plastic frame, and the plastic frame softness is solid, and quality is also lighter, has reduced the labour intensity the when operator works.
Be detachable the connection between power brick 6 among the present invention and the rigid frame 2, in actual use, by the quick-locking device 5 that is symmetrical set on the frame body 22 power brick 6 is fixedlyed connected with rigid frame 2, by soft solid braces 3 and waistband 4 power brick 6 is carried on the back on human body then, be connected with power supply lead wire 8 on the power brick 6, power supply lead wire 8 is supplied with hand held electric tool or garden instrument with electricity, and the operator just can begin to carry out work.If power brick 6 is unloaded from rigid frame 2, as long as pin quick-locking device 5 once more, make it to throw off with the frame body 22 of rigid frame 2, power brick 6 just can be shirked from rigid frame 2 apace.
The invention has the beneficial effects as follows: adopt reliablely and stablely self-contained battery bag of rigid frame, quick-locking device be set on the rigid frame, prevent to bend over or during other postures power brick skid off and hurt sb.'s feelings; The part that the rigid frame back side contacts with human body is adopted netted ventilative cloth, and is ventilative comfortable, can not cough up the body of hurting sb.'s feelings; By the solid braces of softness, waistband the power brick back of the body on human body, is not increased the gripping weight of two hands, the labour intensity when the reduction operator works, easy and convenient.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
