Description
Technical field
The utility model is related to a kind of pneumatic handheld tool, especially a kind of Pneumatic breaking pickaxe.
Background technology
Pneumatic breaking pickaxe is to utilize the hand-held construction equipment of percussion crushing hard objects using compressed air as power.
Because compressed air is to enter cylinder body from the single-sided side walls of cylinder body in existing Pneumatic breaking pickaxe structure, in cylinder body
Hammer body is also easy to produce mechanical wear because the compressed air stream of its side direction impacts between hammer body and cylinder side wall.For example, being existed by applicant
The one kind of first to file, Patent No. ZL201420199871.6 announced provided in Chinese utility model patent document is pneumatic
Breakup pick.
Therefore, applicant feels the need to make further structure improvement to existing above-mentioned Pneumatic breaking pickaxe structure.
Utility model content
It is more preferable that a kind of reasonable structure is provided purpose of the utility model is to solve above-mentioned the deficiencies in the prior art
Pneumatic breaking pickaxe.
To achieve the goals above, a kind of Pneumatic breaking pickaxe designed by the utility model, including a formation hand-held part
And the shank body and a pick body of inlet channel, the bottom of the shank body is equipped with installation cavity, and inlet channel connects with installation cavity,
The cylinder body opening of the pick body is equipped with sealed valve cap, and extends into installation cavity, and is mutually fixed with installation cavity, in the pick
Body is equipped with the gas channel positioned at cylinder body side, and the tail portion of the gas channel is equipped with first through hole, and it is logical that head is equipped with second
Hole, the first through hole make gas channel connect with cylinder body, and second through-hole makes gas channel mutually be passed through with installation cavity
Logical, the sealed valve cap is equipped at least one, is used to realize that aforementioned installation cavity connects and compressed air outlet with cylinder body
Towards the third through-hole of cylinder base, the bore summation of above-mentioned third through-hole is greater than the bore of aforementioned second through-hole.
A kind of Pneumatic breaking pickaxe provided in above-mentioned is open by the compressed gas of inlet channel from cylinder body in structure
Corresponding sealed valve cap position directly enters cylinder body, ensures the compressed air stream direction for initially entering cylinder body and hammer body in cylinder body
The direction of motion is consistent, can thoroughly avoid " compressed gas enters cylinder body from the side direction of hammer body causes hammer body to bias "
The case where occur, to be also easy to produce machinery between hammer body and cylinder side wall in the existing Pneumatic breaking pickaxe structure of effective solution
The technical issues of abrasion.
Preferably, the quantity of above-mentioned third through-hole is three, and it is uniformly distributed along the circumferencial direction of sealed valve cap.
A kind of Pneumatic breaking pickaxe that the utility model obtains, it is good to have a reasonable structure, low using failure rate, effectively makes
With series of advantages such as long lifespans.
Description of the drawings
Fig. 1 is that the present embodiment provides a kind of structural schematic diagram of Pneumatic breaking pickaxe；
Fig. 2 is the partial enlargement structural representation at A in Fig. 1.
In figure：Hand-held part 1, inlet channel 2, shank body 3, pick body 4, installation cavity 5, cylinder body 6, sealed valve cap 7, first through hole 8,
Second through-hole 9, third through-hole 10, hammer body 11.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of Pneumatic breaking pickaxe provided in the present embodiment, including one formed hand-held part 1 and
The bottom of the shank body 3 of inlet channel 2 and a pick body 4, the shank body 3 is equipped with installation cavity 5, and inlet channel 2 and 5 phase of installation cavity
The opening of cylinder body 6 of perforation, the pick body 4 is equipped with sealed valve cap 7, and extends into installation cavity 5, and solid with 5 phase of installation cavity
It is fixed, the gas channel positioned at 6 side of cylinder body is equipped on the pick body 4, the tail portion of the gas channel is equipped with first through hole 8,
Head is equipped with the second through-hole 9, so that gas channel connects with cylinder body 6, second through-hole 9 makes to bring about the desired sensation the first through hole 8
Circulation road connects with installation cavity 5, is set on the sealed valve cap 7 there are three being evenly distributed with along the circumferencial direction of the sealed valve cap,
Connect for realizing aforementioned installation cavity 5 and cylinder body 6 and compressed air outlet towards 6 bottom of cylinder body third through-hole 10, it is above-mentioned
The bore summation of third through-hole 10 is greater than the bore of aforementioned second through-hole 9.
A kind of Pneumatic breaking pickaxe provided in above-mentioned is opened by the compressed gas of inlet channel 2 from cylinder body 6 in structure
Corresponding 7 position of sealed valve cap of mouth directly enters cylinder body 6, ensures to initially enter in compressed air stream direction and the cylinder body 6 of cylinder body 6
The direction of motion of hammer body 11 is consistent, can thoroughly avoid that " compressed gas enters cylinder body 6 from the side direction of hammer body 11 and causes to hammer into shape
There is a situation where bias for body 11 " occur, to hammer body 11 and 6 side of cylinder body in the existing Pneumatic breaking pickaxe structure of effective solution
The technical issues of mechanical wear is also easy to produce between wall.
