Description

Grounding structure of electric screwdriver

Technical Field

The utility model relates to an electronic bottle opener technical field, concretely relates to ground structure of electronic bottle opener.

Background

The electric screwdriver, also called as screwdriver or screwdriver, is an electric tool for screwing and unscrewing a screw and a nut.

The electric screwdriver is likely to be electrified during use for the following reasons: 1. due to short circuit and insulation aging, the electric leakage phenomenon occurs, and parts such as the shaft core of the transmission shaft and the like are electrified; 2. the electric screw driver can generate induced electricity in use; 3. the housing may collect static electricity during the palm holding the power driver. When electric leakage, induced electricity and static electricity are not effectively released, the electric leakage, the induced electricity and the static electricity can flow into equipment through a transmission shaft core and a batch head in the using process, so that electronic components on the equipment are damaged, and property loss is caused; when a human body contacts a charged body, personal injury may be caused, and therefore, it is necessary to reliably ground the electric screwdriver. When the shaft core of the transmission shaft of the electric screw driver is reliably grounded, the resistance of the transmission shaft connected with the ground wire is smaller, the potential of the transmission shaft of the electric screw driver is equal to the ground, and when a screw is locked, the product cannot be damaged.

Therefore, the conventional electric screw driver can be provided with a grounding structure for protecting safety, and the conventional grounding safety protection mechanism comprises a copper sleeve, a lower clutch cylinder, a transmission shaft and other conventional structures.

During the operation of the specific embodiment, the inventor finds the following defects:

in the traditional structure, the copper sleeve is easy to wear, mechanical friction exists in long-term use, the copper sleeve and the axis wear, the gap is too large, poor grounding occurs, the grounding stability is greatly influenced, the copper sleeve needs to be replaced regularly to keep the grounding effect, and the structure has the defect of affecting the reliability of the product.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved by the utility model

Technical scheme

In order to achieve the above purpose, the utility model provides a technical scheme does: the utility model provides a ground structure of electronic bottle opener, includes electronic bottle opener, electronic bottle opener bottom is equipped with down clutch barrel, be equipped with the ground spring in the clutch barrel down, clutch barrel step face under the ground spring one end is passed through the gasket laminating, the bearing inner race is connected to the ground spring other end, the inside transmission shaft that is equipped with of bearing.

Furthermore, the grounding spring is a nickel-plated left-handed spring.

Furthermore, the lower clutch cylinder is made of a conductive material, and a rotating thread is arranged on the outer side of the lower clutch cylinder.

Further, the gasket is made of stainless steel.

Advantageous effects

Adopt the technical scheme provided by the utility model, compare with prior art, have following beneficial effect:

the utility model relates to a rationally, set up ground spring under electronic bottle opener on the clutch section of thick bamboo for derive when electronic bottle opener electric leakage, electric shock electric current, response electricity, static pass through ground spring by the leading-in ground wire of transmission shaft axle core, clutch section of thick bamboo subassembly under the flexible contact of ground spring, and wearing and tearing are little, and electrically conductive effectual, and then prolong its ground connection safety protection's time.

Detailed Description

In order to facilitate understanding of the invention, the invention will be described more fully hereinafter with reference to the accompanying drawings, in which several embodiments of the invention are shown, but which can be embodied in many different forms and are not limited to the embodiments described herein, but which are provided so as to render the disclosure of the invention more thorough and complete.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "page", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," "provided," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Examples

Referring to the attached drawings 1-2, the grounding structure of the electric screw driver comprises an electric screw driver 1, wherein a lower clutch cylinder 2 is arranged at the bottom of the electric screw driver 1, a grounding spring 3 is arranged in the lower clutch cylinder 2, one end of the grounding spring 3 is attached to the step surface of the lower clutch cylinder 2 through a gasket 4, the other end of the grounding spring 3 is connected with an inner ring of a bearing 5, and a transmission shaft 6 is arranged in the bearing 5.

The grounding spring 3 is a nickel-plated left-handed spring, has higher hardness and is consistent with the rotation direction of the electric screw driver 1, so that the service life of the whole electric screw driver is ensured.

Lower clutch cylinder 2 chooses the conductible material for use, for example aluminium, steel, and lower clutch cylinder 2 outside is equipped with rotatory screw thread 21, and the ground connection device can be dismantled in the rotatory screw thread 21 outside for thereby export the ground connection safety protection to equipment and lock payment work piece with the electric current.

The gasket 4 is made of stainless steel, and prevents the grounding spring 3 from directly contacting with the lower clutch barrel 2 to cause abrasion.

The structure of the electric screw driver 1 of the present device is prior art, the technical improvement point is the grounding structure, and the rest structures are prior art known by those skilled in the art, so the electric screw driver equipped with the present protection structure is all within the protection scope of the present application.

When the electric screw driver 1 locks a screw, if the conditions of electric leakage, induced electricity, static electricity and the like occur, the current can pass through the inner ring of the bearing 5, the grounding spring 3, the gasket 4 and the lower clutch cylinder 2 through the transmission shaft 6 and can be conducted away through the grounding device on the lower clutch cylinder 2, so that the grounding safety protection of equipment and a locking workpiece is realized.
