Based on this, it is necessary to provide a dust cover for the situation that the existing electric drill cannot prevent dust during drilling, which can effectively collect dust generated during drilling, prevent dust from splashing around, and protect the health of operators.

The utility model provides a dust cover, includes the sucking disc, flexible cover, mount pad and sealed bearing, flexible cover is the loudspeaker form, the great one end of flexible cover diameter with the sucking disc is connected, the less one end of flexible cover diameter with the connection can be dismantled to the mount pad, be provided with the dust collecting tube on the sucking disc, the mount pad includes closing plate and spacing pipe, spacing pipe mounting is in closing plate one side, the closing plate deviates from one side of spacing pipe is provided with the recess, the recess with spacing pipe is with the axle center intercommunication, sealed bearing installs in the recess.

Preferably, a plurality of bulges are arranged in the sucker.

Preferably, the sealing plate edge is provided with a bolt hole, the end plate is arranged at the end with the smaller diameter of the telescopic cover, and a bolt penetrates through the bolt hole and is connected with the end plate.

Preferably, the telescopic cover is made of transparent plastic.

The utility model discloses an useful part lies in: 1. the telescopic characteristic of the telescopic cover is utilized to ensure that the electric drill can drill holes normally, and the sucking disc is additionally arranged at the contact end of the telescopic cover and the wall surface, so that the connection sealing property between the dust cover and the wall surface is improved, dust is prevented from overflowing from a gap between the dust cover and the wall surface, and the body health of an operator is protected; 2. utilize the mount pad to be connected with the electric drill to set up spacing pipe on the mount pad, avoid the electric drill to bore into the wall body too deeply, lead to the electric drill fracture, effectively protect the electric drill body.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a dust cover comprises a suction cup 1, a telescopic cover 2, a mounting seat 3 and a sealing bearing 4, wherein the telescopic cover 2 is in a horn shape, the larger end of the diameter of the telescopic cover 2 is connected with the suction cup 1, the smaller end of the diameter of the telescopic cover 2 is detachably connected with the mounting seat 3, a dust collecting pipe 11 is arranged on the suction cup 1, the mounting seat 3 comprises a sealing plate 31 and a limiting pipe 32, the limiting pipe 32 is arranged on one side of the sealing plate 31, the sealing plate 31 deviates from one side of the limiting pipe 32 and is provided with a groove 311, the groove 311 is communicated with the limiting pipe 32 coaxially, and the sealing bearing 4 is arranged in the groove 311. Specifically, in this embodiment, when in use, the operator first inserts the electric drill 100 into the mounting seat 3, specifically, inserts the electric drill into the mounting seat 3 through the seal bearing 4, and uses the seal bearing 4, so as to prevent dust from overflowing from the gap of the seal bearing 4. Further, the mounting seat 3 is composed of a sealing plate 31 and a limiting pipe 32. When the electric drill 100 during operation, the expansion cover 2 is compressed for spacing pipe 32 and wall body butt, and then utilize spacing pipe 32 to restrict the degree of depth that the electric drill 100 bored into the wall body, prevent because the dust flies upward in the dust cover, lead to operating personnel can not see the degree of depth that the electric drill 100 bored into clearly, lead to that the electric drill 100 bores too deeply, the emergence fracture. Further, it is great with wall body butt one end diameter at expansion shield 2, be convenient for collect the dust to be provided with sucking disc 1, when holing on the ceiling, can utilize sucking disc 1 to adsorb the dust cover on the wall body, and the leakproofness is good between sucking disc 1 and the ceiling, can prevent effectively that the dust from spilling over, ensures that operating personnel can not inhale the dust, guarantees operating personnel's physical and mental health. Further, still be provided with dust collecting tube 11 on sucking disc 1, utilize dust collecting tube 11 and dust catcher (not shown in the figure) to be connected, can in time take away the dust in the dust cover, flexible cover 2 material is made for transparent plastic, is convenient for operating personnel visual observation electric drill 100 behavior.
