Description
Technical field
This utility model relates to a kind of construction implement, the pneumatic structure of a kind of dabbing machine.
Background technology
In order to allow the construction surface of two construction stages be firmly bonded, need construction surface is carried out dabbing, to facilitate next layer
Cast, now commonly use dabbing machine replace Traditional Man manual dabbing operation.
Existing dabbing machine many employings compressed air is as power source, and its pneumatic structure is mainly by piston rod and piston bush structure
Become, make the compressed air in external feed stream pipeline enter the gap between piston bush and piston rod by the air inlet on piston bush
In, thus promote piston rod up-down vibration.The dabbing machine of existing structure, either hand-held or its piston bush of hand propelled are adopted more
Designing with the cylinder of same size, for convenience of piston bush air inlet, need to offer air inlet duct on outside casing, structure designs
Relative complex.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, it is not necessary to the pneumatic knot of the dabbing machine of fluting on casing
Structure.
To achieve these goals, the technical scheme that this utility model is used is:
The pneumatic structure of a kind of dabbing machine, including casing, piston rod and piston bush, piston bush is located in casing, piston rod
One end be located in piston bush, the other end leaks cruelly outside casing；Casing is provided with air inlet, and piston rod inner is provided with air cavity,
Offering air inlet and steam vent on piston rod, steam vent is in the lower section of air inlet, and air inlet is respectively provided at work with steam vent
On the normal of two perpendicular angles of stopper rod cross section；On piston bush, surrounding offers multiple air inlet, and the stage casing of piston bush is straight
Footpath is less than two ends diameter, and the air inlet on piston bush is located at the stage casing of piston bush.
The top being positioned at air inlet on described piston rod is provided with the diameter backhaul point more than diameter of piston rod.
On described piston rod, the top of backhaul point is provided with the diameter annular groove less than backhaul point diameter.
This utility model simple in construction, reasonable in design, by the segment design of piston bush different-diameter, can be directly at casing
On offer air inlet, it is not necessary to offering air inlet groove, structure design is more succinct.
Below by way of the drawings and specific embodiments, this utility model is further elaborated.
Accompanying drawing illustrates:
Fig. 1 is the structural representation after this utility model removes casing and one of them piston bush.
Detailed description of the invention:
Shown in Fig. 1, the pneumatic structure of a kind of dabbing machine that this utility model provides, including casing (omitting in figure),
Piston rod 1 and piston bush 2, piston bush 2 is located in casing, and one end of piston rod 1 is located in piston bush 2, and the other end leaks cruelly at case
External body, is used for connecting dabbing head；Casing is provided with air inlet 3, and piston rod 1 is internal is provided with air cavity, and piston rod 1 offers two
Individual air inlet 13 and two steam vents 14, two air inlets 13 are oppositely arranged, and two steam vents 14 are also oppositely arranged, steam vent 14
In the lower section of air inlet 13, and air inlet 13 is respectively provided at the method for piston rod 1 two perpendicular angles of cross section with steam vent 14
On line；On piston bush 2, surrounding offers multiple air inlet 21, and the stage casing diameter of piston bush 2 is less than two ends diameter, on piston bush 2
Air inlet 21 be located at the stage casing of piston bush 2.
Piston rod 1 in such scheme is provided with backhaul point 11 and annular groove 12, and backhaul point 11 is positioned at the top of air inlet 13,
And diameter is more than the diameter of piston rod 1；Annular groove 12 is positioned at the top of backhaul point 11, and diameter is less than the diameter of backhaul point 11.
There is the dabbing machine of pneumatic structure in such scheme operationally, the air inlet from casing of the outside compressed air
Mouthfuls 3 gaps entering box houses, enter the air inlet 21 from piston bush 2 of the compressed air in casing enter piston bush 2 with
Gap between piston rod 1, then entered the air cavity in piston rod 1 by the air inlet 13 on piston rod 1, compressed air flows up
Being full of the annular groove 12 on piston rod 1 top, compressed air promotes backhaul point 11 impact downwards on piston rod 1, drives dabbing
Head impact concrete surface；Meanwhile, during piston rod 1 moves down, steam vent 14 exposes piston bush 2, and compressed air is by living
Steam vent 14 on stopper rod 1 is discharged, distress resolves.The air inlet 21 that compressed air continues through on piston bush 2 enters piston bush 2
And the gap between piston rod 1, promote the backhaul point 11 on piston rod 1 to make piston rod 1 move up, until on piston rod 1
When the air inlet 21 of air inlet 13 and piston bush 2 is co-located, compressed air is again introduced into the air cavity of piston rod 1, so
Repeatedly work, it is achieved the continuous strike of dabbing head road pavement.
In order to make the intake passage structure on casing more succinct, piston bush 2 is set to different-diameter by the present embodiment
Multi-segment structure, and air inlet 21 is opened in mid diameter relatively segment, so only need to offer air inlet on casing, it is not necessary to
Air inlet groove is set specially, makes structure more succinct.
Above example only in order to the technical solution of the utility model to be described and unrestricted, those of ordinary skill in the art couple
Other amendment or equivalents that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should contain in right of the present utility model.
