Description
Technical field
The utility model belongs to sander technical field, is related to a kind of sander dust discharge tube positioning structure.
Background technique
Wall surface grinding machine be it is a kind of instead of traditional artificial people take sand paper polishing metope or object tool, with reach it is smooth,
Dustless, protection worker's physical and mental health purpose, energy Optimization Work environment improve working efficiency, promote decoration quality.
Currently, traditional sander includes dust flue and the brace being sleeved on dust flue and lever, in dust flue
It is additionally provided with the wire-passing tube for being used for line being affixed on its inner wall, for connecting with polishing pad, lever is held for holding for brace
Handle, brace and dust flue usually open up limit hole when being connected and fixed on dust flue, and corresponding to setting in brace in lever
Limited block, limited block protrudes into limit hole, to realize that lever, brace and dust flue are fixed, meanwhile, by limited block with
Sealant is applied between dust discharge pipe outer wall, to prevent the ash in dust flue from leaking out and entering in brace and lever, still, this structure
There is also following technical problem, sander in use, sealant can because of reasons such as agings, cause dust flue and brace or
Sealing effect between lever is poor, and ash can still be leaked out by dust flue and be entered between lever or brace, and dust enters meeting between brace
It being entered in air by brace, influences user's health, dust enters in lever, then the electric elements in lever can be damaged,
Influence its service life.
In conclusion needing to design one kind not leakiness ash, environmental protection effect to solve above-mentioned sander
Fruit is good and sander dust discharge tube positioning structure with long service life.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, it is grey, environmentally friendly to propose a kind of not leakiness
Effect is good and sander dust discharge tube positioning structure with long service life.
The purpose of this utility model can be realized by the following technical scheme: a kind of sander dust discharge tube positioning structure, packet
The wire-passing tube for including dust flue and being set in dust flue, the wire-passing tube caliber are less than dust flue and are connected with dust flue inscribe,
The brace for connecting polishing pad and the lever for gripping, the outer surface setting of the dust flue are arranged on dust flue
There are the first groove and the second groove being spaced, first groove and the second groove extend to wire-passing tube sunken inside, described
Brace inner surface is convexly equipped with the first convex block and the first convex block is embedded in the first groove, and the lever inner surface is convexly equipped with the second convex block
And second convex block be embedded in the second groove in.
In a kind of above-mentioned sander dust discharge tube positioning structure, the dust flue and wire-passing tube by metal material it is integrated at
Type.
In a kind of above-mentioned sander dust discharge tube positioning structure, first groove and the second groove use impact style one
Secondary molding.
Compared with prior art, the utility model has the following beneficial effects:
1, the first groove and the second groove protruded into wire-passing tube is opened up on dust flue, and by brace and lever
The first convex block is respectively set and the second convex block is matched, so that brace, lever and dust flue, which are realized, connects simultaneously axially position, three
Person's locating effect is preferable.
2, the first groove and the second groove protrude into cable-through hole, avoid the aperture on dust flue, effectively prevent dust discharge
Dust in pipe is leak into brace or lever, and environment protecting is preferable, and use is safe, and the electric elements in lever can be prevented impaired.
3, material is saved, is reduced costs without applying sealant on dust flue using this structure.
Detailed description of the invention

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 and Figure 2, a kind of 10 location structure of sander dust flue of the utility model, including dust flue 10 and setting
In the wire-passing tube 11 in dust flue 10,11 caliber of wire-passing tube is less than dust flue 10 and is connected with 10 inscribe of dust flue, is arranging
The brace 20 for connecting polishing pad and the lever 30 for gripping, the outer surface of the dust flue 10 are arranged on dirt pipe 10
It is provided with the first groove 12 and the second groove 13 being spaced, first groove 12 and the second groove 13 are into wire-passing tube 11
Recess extends, and 20 inner surface of brace is convexly equipped with the first convex block 21 and the first convex block 21 is embedded in the first groove 12, described to hold
30 inner surface of handle is convexly equipped with the second convex block 31 and the second convex block 31 is embedded in the second groove 13.
The utility model after adopting the above structure, by the first groove 12, the second groove 13 respectively with the first convex block 21,
The cooperation of two convex blocks 31, realizes that brace 20, lever 30 is connect with dust flue 10 and axially position, three's locating effect is preferable, together
When, the first groove 12 and the second groove 13 protrude into cable-through hole, avoid the aperture on dust flue 10, effectively prevent dust flue
Dust in 10 is leak into brace 20 or lever 30, and environment protecting is preferable, and use is safe, can prevent the electric elements in lever 30
It is impaired.
On the basis of the said structure, the utility model has been made it to be further improved and refined.
As shown in Fig. 2, the dust flue 10 is integrally formed with wire-passing tube 11 by metal material, it is integrally formed the row of improving
The intensity of dirt pipe 10 and wire-passing tube 11 is avoided generating deformation when the first groove 12 and the second 13 stress of groove, while can also be improved
The bonding strength of dust flue 10 and brace 20, lever 30.
Further, the first groove 12 and the second groove 13 use impact style one-pass molding, and integrated molding simplifies the
The moulding process of one groove 12 and the second groove 13 also effectively reduces cost so that its production is simply, conveniently.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
