Abstract
The utility model relates to a battery pack for an electric tool, which belongs to the technical field of electric tools. The battery pack comprises a shell body composed of an upper shell and a lower shell which can be fastened mutually. The upper portion of the shell body is provided with a locking mechanism tightly inserted with an electric tool body, a battery set is arranged inside the shell body, and the bottom surface of the lower shell forms a supporting surface. The battery pack for the electric tool is characterized in that a recess for containing a fingertip is arranged on the bottom surface of the lower shell corresponding to the interval of two adjacent batteries. Under the condition of not affecting original functions of the battery pack, the space at the interval of the adjacent batteries is provided with the bottom surface recess, so that inconvenience of the battery pack in detachment is solved reasonably, and the electric tool is used with facility.
Description
Technical field
The utility model relates to a kind of power brick, and especially a kind of power tool battery bag belongs to the electric tool technical field.
Background technology
Power brick is the indispensable auxiliary equipment of direct current electric power tools such as electric hand drill.Existing this type of power brick contains the housing that is made up of the upper and lower casing of mutual fastening, and the tight mortise lock that said housing top has with power tool body closes mechanism, the positioned inside battery pack, and the bottom surface of said lower casing constitutes supporting surface.Its typical structure can be referring to the one Chinese patent application of application number for (the direct current electric power tools application number of the automatic demonstration electric weight of applying for not long ago on please filling in).
When needs are changed battery, power brick is unloaded from power tool body, open upper casing again and get final product.But facts have proved that the structure of existing power brick has inconvenience more when making it being separated with power tool body.Because when pulling down power brick, should remove locking mechanism, overcome again and tight insert resistance, if take to pinch above the power brick dismounting mode with the bottom surface, need apply bigger active force, otherwise be not enough to overcome the tight resistance of inserting.Another kind of dismounting mode is to hold the power brick bottom surface with palm, with pointing the rear wall that fastens power brick, so that the application of force.Yet this mode is for the relatively large power brick of volume, because finger is difficult to the safe power brick rear wall that fastens, and therefore dismounting effort still.
The utility model content
The purpose of the utility model is: the inconvenience that exists to above-mentioned prior art through the architecture advances to existing power brick, proposes a kind of and power tool body lock out operation power tool battery bag easily.
In order to reach above purpose, the utility model power tool battery includes the housing that is made up of the upper and lower casing of mutual fastening; The tight mortise lock that said housing top has with power tool body closes mechanism, the positioned inside battery pack; The bottom surface of said lower casing constitutes supporting surface; Its improvements are that the bottom surface of said lower casing is shaped on the depression of holding finger tip at the adjacent cell interval of the said battery pack of correspondence.
Like this, during owing to the dismounting power brick, finger can be scratched the depression of the casing bottom surface of staying, and therefore is convenient to the application of force, thereby when removing locking mechanism, overcomes tight slotting resistance easily, and power brick is disassembled from power tool body.The utility model is under the situation that does not influence the power brick original function, and the bottom surface depression is processed in the ingenious space at battery interval place that utilizes, and has rationally solved the dismounting inconvenience problem of power brick, makes electric tool more handy.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment two.
Fig. 4 is the structural representation of the utility model embodiment three.
Embodiment
Embodiment one
Present embodiment is a kind of and the supporting power tool battery bag of hand held electric drill, and its structure is as depicted in figs. 1 and 2, and housing is made up of with lower casing 4 upper casing 3 of mutual fastening.Housing top has and is used for and the slot of power tool body bottom plug-in mounting and the locking mechanism of lock-button 1 formation positioned inside one Battery pack 2.After power brick and drill body plug-in mounting were fixing, the bottom surface of lower casing 4 had constituted the supporting surface of hand held electric drill.For the ease of the dismounting power brick, the bottom surface of lower casing 4 is shaped on a V-arrangement cross section depression elongated slot 5 that holds finger tip at the interval of corresponding battery pack adjacent cell 4.
When the dismounting power brick; Any finger tip except that thumb is scratched the depression elongated slot of the casing bottom surface of staying, and can use the thumb press lock-button, when releasing power brick and drill body are sealed; Overcome the tight resistance of inserting easily, power brick is taken out from power tool body unload down.Because the depression elongated slot is positioned at the space at battery interval place, therefore the original function to power brick has no influence, and is practical.
Embodiment two
The power tool battery bag of present embodiment is as shown in Figure 3, and basic structure is identical with embodiment one, and difference is that the bottom surface of lower casing 4 is shaped on two parallel recesses elongated slots that hold finger tip at the interval of corresponding battery pack adjacent cell 4.Like this, different users can select to scratch the depression elongated slot into correct position according to s own situation.
Embodiment three
The power tool battery bag of present embodiment is as shown in Figure 4, and basic structure is also identical with embodiment one, and difference is that the bottom surface of lower casing 4 is shaped on two oval nests of depression that hold finger tip at the interval of corresponding battery pack adjacent cell 4.When needs unload power brick, when pressure-locking button, scratch the oval nest that firmly caves in respectively with other two fingers and take out to unload and get final product.
The foregoing description is nonrestrictive, and the utility model can also have other execution modes.For example, the quantity of recessed groove or depression nest can be more, and the shape of elongated slot can be tortuous waveform, and cross sectional shape can be semicircle; The shape of depression nest can be other geometry.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
