The axial restraint of connector inner casing component 1.Wherein, the axis of the preferred connecting pin 4 of the present embodiment is vertical with the axis of intercommunicating pore 10, real
The fixation of existing distribution bar 5 and connector inner casing component 1;In addition, in the present embodiment further preferably 4 through-thickness penetrator of connecting pin
The side wall of cylinder component 1, user's control connecting pin 4 sequentially pass through the first fixation hole and the second fixation hole, can be completed distribution bar 5 with
The assembly of connector inner casing component 1, had both facilitated the assembly of user, also ensured the fixed effect of the two.It should be understood that connecting pin 4
Axis and connector inner casing component 1 radial direction have certain angle, can still realize the axial direction of distribution bar 5 Yu connector inner casing component 1
It is fixed.
Optionally, in order to reinforce the fixed effect of distribution bar 5 Yu connector inner casing component 1, the two radially uses small―gap suture
Cooperation positioning.That is, the lateral wall of distribution bar 5 and the inner sidewall of connector inner casing component 1 are fitted and connected, to avoid distribution bar 5
Radial shake.
Further, in order to optimize the using effect of impactor, in a kind of embodiment provided by the present application, 5 court of distribution bar
It is equipped with non-return valve 2 to one end of connector 101, is equipped between non-return valve 2 and distribution bar 5 for adjusting 2 axial position of non-return valve
Elastic component 3.Specifically, the intercommunicating pore 10 of connector inner casing component 1 is stepped, the setting of non-return valve 2 step surface region and with this
Region fitting offsets;Elastic component 3 can be along the axial stretching of connector inner casing component 1.During the work time, high pressure gas is from pneumatics
Machine enters inside intercommunicating pore 10, and it is mobile to the direction close to inner casing 102 to push non-return valve 2, and non-return valve 2 offsets with being bonded at this time
Step surface separation, gas enter impactor front and back chamber acting, realize rock drilling operation.
Optionally, the end of distribution bar 5 is equipped with the slide opening axially extended;Non-return valve 2 include in connector inner casing component 1
The frustum of side wall fitting and the slide bar connecting with frustum end face, slide bar are set in slide opening;The middle part of slide bar is connected to equipped with elastic component
Hole, elastic component 3 are set in elastic component intercommunicating pore.
Specifically, the sectional area of frustum is gradually increased from end to the direction close to slide bar, lateral wall and intercommunicating pore 10
Stepped area fitting offset, while the end face of frustum can be bonded with the end face of slide opening and offset, and realize the limit of frustum;In work
During work, the on off operating mode of the i.e. controllable high pressure gas of axial position of frustum is controlled.
Slide bar is set to one end of frustum, extends in the slide opening of distribution bar 5, and slide bar can be axially sliding in slide opening
It is dynamic, while slide opening is provided with and is bonded the confined planes to offset with slide bar end face.The end face of confined planes and frustum is jointly to non-return valve 2
Position is defined.
Elastic component 3 can be spring or rubber column or other flexible elements, be arranged inside slide bar, elastic component
3 one end be bonded with the end face of slide bar inner elastomeric part intercommunicating pore offset, the other end is bonded with the confined planes of distribution bar 5 and offsets.It is high
Elastic component 3 compresses when pressing gas push non-return valve 2 mobile, and when the insufficient pressure of high pressure gas, elastic component 3 utilizes itself bullet
Property push non-return valve 2 to be bonded and offset with the inner sidewall of connector inner casing component 1.
Further, in order to optimize the using effect of impactor, on the basis of any one above-mentioned embodiment, in connector
Cylinder component 1 is equipped with air distribution hole 9, and the axis of air distribution hole 9 intersects with the axis of intercommunicating pore 10 or antarafacial, to improve gas circulation
Fluency.
In the prior art, air distribution hole 9 is generally arranged in distribution seat, and along the axially extending of distribution seat, while in inner casing
The stomata that 102 settings extend radially through.During the work time, gas enters stomata from air distribution hole 9, due to air distribution hole 9 and stomata
It is vertically arranged, therefore the resistance of gas flowing is larger.
In the present embodiment, air distribution hole 9 is arranged on connector inner casing component 1, and air distribution hole 9 uses oblique hole structure, i.e. distribution
The central axis of the relatively close inner casing 102 in 9 one end of hole, and the other end is relatively distant from central axis.When high pressure gas pushes non-return valve 2 to move
When dynamic, high pressure gas can be flowed from 7 direction of outer shell of the oblique impactor of air distribution hole 9, and oblique hole structure reduces the length of air distribution hole 9
The form of gas passage is spent, changed simultaneously, and then reduces the resistance of gas circulation, keeps gas flowing more smooth, and mention
The aperture speed of HI high impact device.
Further, in the spacing of air distribution hole 9 and 10 axis of intercommunicating pore from 9 one end of air distribution hole to the side close to inner casing 102
To being gradually increased.Specifically, between outer shell 7 and inner casing 102 with supplied gas circulation gas passage 8,9 first end of air distribution hole with
The connection of intercommunicating pore 10 of connector inner casing component 1, second end are connected to the gas passage 8 outside inner casing 102, and air distribution hole 9 first
Hold the distance of 1 central axis of connector inner casing component smaller, the distance of second end to 1 central axis of connector inner casing component is larger.In work
During work, high pressure gas pushes non-return valve 2 to after movement, and gas passes sequentially through intercommunicating pore 10, air distribution hole 9 and gas passage 8,
And then control the reciprocating movement of piston 6.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
Impactor provided by the present invention is described in detail above.Specific case used herein is to the present invention
Principle and embodiment be expounded, method and its core of the invention that the above embodiments are only used to help understand
Thought is thought.It should be pointed out that for those skilled in the art, without departing from the principle of the present invention,
Can be with several improvements and modifications are made to the present invention, these improvement and modification also fall into the protection scope of the claims in the present invention
It is interior.
