Description

Elastic positioning plug of electric tool

Technical Field

The utility model belongs to the technical field of electric tool spare part, refer in particular to an electric tool's elastically positioned plug.

Background

The power supply of the lithium battery direct current tool is a battery pack, and the lithium battery direct current tool is in quick-change plug-in connection with the tool. The quick change plug of the lithium electricity direct current instrument in the present society all is immovable structure, also is the casing fixed plug, and the plug is inserted on the battery package, because the draw-in groove of battery package and casing all is the working of plastics, through the mould shaping, warp great, form and position tolerance is great when leading to battery package and plug cooperation, produces the spark with the socket of battery package easily, and especially lithium electricity instrument electric current is big, and vibrates greatly, appears the spark more easily. This structure seriously affects the life span of the battery pack.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a stable in structure, simple to operate, long service life's electric tool's elastically positioned plug.

The purpose of the utility model is realized like this: the utility model provides an electric tool's elastic positioning plug, is including installing left casing and the right casing on the battery package, be equipped with the plug between left side casing and the right casing, the equal shaping in plug both ends has the spacing arch with left casing and right casing looks joint, plug one side is equipped with the spring, spring other end butt is on left casing.

Preferably, the left casing and the right casing are both provided with limiting grooves, and limiting bulges are arranged in the limiting grooves in a sliding mode.

Preferably, mounting grooves are formed in the left casing and the right casing, and the plug is slidably arranged in the mounting grooves.

Preferably, a limiting lug is formed on one side of the plug, and the spring is sleeved on the limiting lug.

Compared with the prior art, the utility model outstanding and profitable technological effect is: the elastic positioning plug and the shell of the electric tool of the utility model are in a dovetail groove structure; the plug can slide in the shell and is positioned by the pressure of the positioning spring; the form and position deviation between the plug and the battery pack can be eliminated by the pressure of the spring; the plug and the battery pack are always in close contact, and no spark is generated.

Drawings

Fig. 1 is an exploded view of the present invention;

fig. 2 is a schematic view of the plug of the present invention.

Detailed Description

The invention will be further described with reference to specific embodiments.

As shown in fig. 1-2, an elastic positioning plug of electric tool, including installing left casing 1 and right casing 2 on the battery package, be equipped with plug 3 between left side casing 1 and the right casing 2, 3 both ends of plug all the shaping have with left casing 1 and right casing 2 spacing arch 4 of looks joint, 3 one side of plug is equipped with spring 5, the other end butt of spring 5 is on left casing 1.

Preferably, all seted up spacing recess 6 on left casing 1 and the right casing 2, it is equipped with spacing arch 4 to slide in spacing recess 6.

Preferably, the left casing 1 and the right casing 2 are provided with mounting grooves 7, and the plug 3 is slidably disposed in the mounting grooves 7.

Preferably, a limiting bump 8 is formed on one side of the plug 3, and the spring 5 is sleeved on the limiting bump 8.

The assembly sequence is as follows: 1. the plug is arranged between the left shell and the right shell; 2. the spring is arranged between the left and the right machine cases 3, the screws 4 of the left and the right machine cases are screwed, and the plug is inserted into the battery pack.

The principle is as follows: the spring 5 is arranged between the plug 3 and the left and right casings, and the spring 5 keeps 3-4 kg pressure in a compressed state, after the parts are assembled, the plug 3 and the casings are in a dovetail groove structure and are mainly positioned by the pressure of the spring 5, when the battery pack is connected with the plug, because the plug is movably connected with the left and right casings, the shape and position deviation between the casings and the plug 3 is automatically eliminated, and under the pressure of the spring 5, the plug 3 is stably connected with the battery pack, and the spark cannot be generated. The service life of the battery pack is prolonged.

The elastic positioning plug of the electric tool and the shell of the electric tool adopt a dovetail groove structure; the plug can slide in the shell and is positioned by the pressure of the spring 5; the form and position deviation between the plug 3 and the battery pack can be eliminated by the pressure of the spring 5; the plug 3 and the battery pack are always in close contact, and no spark is generated.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
