End cap further includes having interior air pressure balance cover and outer air pressure balance cover, and the interior air pressure balance enclosure is set in lens barrel lower cover
And air pressure balance chamber in being formed between lens barrel lower cover, the outer air pressure balance enclosure are set to outside lens barrel lower cover, lens barrel
Lower cover bottom is equipped with opening and is connected to form outer air pressure balance chamber with outer air pressure balance cover, the outer air pressure balance chamber and interior gas
Counter balance pocket is pressed to pass through seal receptacle interval.
Preferably, the interior air pressure balance cover includes pedestal and is set to pressure tank on pedestal, and the outer gas flattens
The weighing apparatus enclosure is set to pressure tank outer surface and outer air pressure balance cover is bolted with pedestal.
Preferably, the lens barrel lower cover includes lens barrel and the upper mounting seat at the top of lens barrel, the lens barrel
Diameter be greater than pressure tank diameter.
Preferably, the sealed socket sleeve is set on the lateral wall of lens barrel bottom, the lateral surface of the seal receptacle and outer
The inner sidewall of air pressure balance cover contradicts sealing.
Preferably, the seal receptacle is round rubber circle.
Preferably, the limited step that can be contradicted with seal receptacle is equipped at the top of the outer air pressure balance cover inner sidewall.
Preferably, the lens barrel is equipped with several via holes, and the via hole is set to below seal receptacle.
Preferably, several rounded arrays of via hole are distributed in lens barrel bottom.
The beneficial effects of the utility model are: the relatively interior air pressure balance cover of lens barrel and outer air pressure balance cover move constantly relatively,
When interior air pressure balance chamber volume is while increasing, the volume of outer air pressure balance chamber is then gradually reduced, conversely, working as interior air pressure balance
While reducing, the volume of outer air pressure balance chamber is then increasing the volume of chamber, by this structure, guarantees interior air pressure balance chamber
It is roughly equal with the volume of outer air pressure balance chamber, to realize that the intracorporal volume of entire chamber is held essentially constant, form a gas
Pressure compensation solves the problems, such as to guarantee using the atmospheric pressure compensating structure of the design saturating due to the mobile generated gas differential pressure of lens
In mirror moving process, cutting head air pressure inside balance, lens are mobile steady, guarantee cutting effect.
The utility model embodiment is described further with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the explosive view of the utility model embodiment；
Fig. 2 is the structure chart of the utility model embodiment China and foreign countries air pressure balance cover；
Fig. 3 is the front view of the utility model embodiment；
Fig. 4 is the A of Fig. 3 in the utility model embodiment to cross-sectional view.
Specific embodiment
As Figure 1-Figure 4, the utility model provides a kind of laser cutting head atmospheric pressure compensating structure, includes lens barrel lower end
Lid 1 further includes having interior air pressure balance cover 2 and outer air pressure balance cover 3, and the interior air pressure balance cover 2 is sheathed on lens barrel lower cover 1
It is interior and air pressure balance chamber 21, the outer air pressure balance enclosure 3 are set to lens barrel lower cover 1 in being formed between lens barrel lower cover 1
Outside, 1 bottom of lens barrel lower cover is equipped with opening and forms outer air pressure balance chamber 31, the outer air pressure with the conducting of outer air pressure balance cover 3
Counter balance pocket 31 is spaced with interior air pressure balance chamber 21 by seal receptacle 4.In above scheme, when the relatively interior air pressure of lens barrel lower cover 1 is flat
Weighing apparatus cover 2 and outer air pressure balance cover 3 move when, when the volume of interior air pressure balance chamber 21 increase when, the appearance of outer air pressure balance chamber 31
Product is gradually reduced, conversely, the volume of outer air pressure balance chamber 31 then gradually increases when the volume of interior air pressure balance chamber 21 is when reducing
Greatly, it generally remains equal between the two, to make the entire intracavitary constancy of volume, forms atmospheric pressure compensating, solve to move due to lens
Gas differential pressure problem caused by dynamic is guaranteed in lens travel, in cutting head using the atmospheric pressure compensating structure of the design
Portion's air pressure balance, lens are mobile steady, guarantee cutting effect.
The interior air pressure balance cover 2 includes pedestal 22 and the pressure tank 23 on pedestal 22, the outer air pressure
Balance cover 3 is sheathed on 23 outer surface of pressure tank and outer air pressure balance cover 3 is bolted with pedestal 22.By above-mentioned setting,
Realize the connection of interior air pressure balance cover 2 and outer air pressure balance cover 3, stable structure.
The lens barrel lower cover 1 includes lens barrel 12 and the upper mounting seat 13 set on 12 top of lens barrel, the lens barrel
12 diameter is greater than the diameter of pressure tank 23.The diameter of lens barrel 12 is greater than the diameter of pressure tank 23, and therefore, 12 sets of lens barrel in air pressure
The outside of cylinder 23, the space between the inside and pressure tank 23 of lens barrel 12 are interior air pressure balance chamber 21.
The seal receptacle 4 is sheathed on the lateral wall of 12 bottom of lens barrel, the lateral surface of the seal receptacle 4 and outer air pressure
The inner sidewall of balance cover 3 contradicts sealing.Seal receptacle 4 plays sealing function, when lens barrel 12 during exercise, seal receptacle 4 follows lens barrel
12 move along outer 3 inner sidewall of air pressure balance cover, play the role of separating in interior air pressure balance chamber 21 and outer air pressure balance chamber 31.
The seal receptacle 4 is round rubber circle.Rubber ring is at low cost, and sealing effect is good, and has certain elasticity,
When being moved along outer air pressure balance cover inner sidewall, will not be worn with the inner sidewall.
The limited step 41 that can be contradicted with seal receptacle is equipped at the top of outer 3 inner sidewall of air pressure balance cover.Limited step
41 play position-limiting action, and when lens barrel moves, and seal receptacle is contradicted to limited step, lens barrel stop motion prevents lens barrel from falling off.
