Abstract
The utility model relates to an air cylinder cover which comprises a cylinder cover. An air inlet is arranged in the lower part of the cylinder cover. The air cylinder cover is characterized in that an run-through installation hole is arranged above the air inlet, an air valve seat is arranged in the installation hole as well as is positioned above the air inlet, a bolt is in bolt joint with the upper part of the installation hole in a sealing way, and a spring is arranged supporting against between the bolt and the air valve seat; an air outlet is communicated with the installation hole and the external. In the structure, a plurality of sealing rings which are needed to be used in the prior art are banished, ageing of materials is avoided, the structure is simple, the assembly is easy and convenient, and the running reliability is high.
Description
Technical field
The utility model relates to air pump assembly, specifically refers to a kind of cylinder head.
Background technique
Air cylinder head structure in the market as shown in Figures 2 and 3, it is by cylinder cap 1 ', big sealing ring 2 ', valve seat 5 ', shell fragment 3 ' and small sealing ring 4 ' are formed, its assembly structure is as shown in Figure 2.Enter in the valve port that has air-flow that piston motion produces to offer from valve seat 5 ' behind cylinder sleeve, air-flow blows shell fragment 3 ' and heaves, and gas enters the air outlet hole 6 ' discharge on the cylinder cap 1 ' from overflowing shell fragment 3 ' and cooperating the slit of valve seat 5 '.Because the component of this cylinder head are more, used two seal rings, the product assembling is complicated, and because mismatch error between each part and material aging, running stability is also relatively poor.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides that a kind of stationarity is good, the air pump cylinder head of easy assembling.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this cylinder head, comprise cylinder cap, be provided with inlet hole in the bottom of described cylinder cap, it is characterized in that: the top of described inlet hole is provided with the mounting hole of perforation, valve seat is arranged in the mounting hole and is seated in the top of described inlet hole, the top seal of mounting hole is bolted with bolt, supports being provided with spring between described bolt and the valve seat; Air outlet hole is communicated with the described mounting hole and the external world.This structure abandoned in the prior art a plurality of seal rings that must use, avoided the aging of material, and simple in structure, assemble easy and convenient, the operational reliability height.
Preferably, described air outlet hole is axially vertical with described mounting hole.
As the improvement of such scheme, described valve seat is " protruding " font, and the projection of its upper end is located in the described spring, and this structure makes things convenient for the spacing of spring.
Compared with prior art, the utility model is cooperating by valve seat and spring only, can finish the function of unidirectional exhaust, abandon a plurality of rubber seal that to use in the prior art, solve the maintenance that brings because of material aging and the problem of fluctuation of service; And the design of mounting hole top bolt makes that the installation and removal of this cylinder head are all very convenient; Simultaneously, because these cylinder head component are fewer, its cost of production has also obtained reduction.

Fig. 2 is the three-dimensional exploded view of the utility model background technique;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in 1, this cylinder head comprises cylinder cap 1, is provided with inlet hole 5 in the bottom of described cylinder cap 1, and the top of inlet hole 5 is provided with the mounting hole 7 of perforation, and air outlet hole 6 and described mounting hole are axially vertical and be communicated with the described mounting hole and the external world.The top of described inlet hole 5 has been located valve seat 2, and in the present embodiment, described valve seat is " protruding " font, and spring 3 is located in the projection of valve seat upper end, and its lower end is to being located on the valve seat.Bolt 4 and make it to form sealing with the perisporium of mounting hole 7 is spirally connected in the mounting hole above spring 3.Like this, the two ends of spring 3 are supported respectively and are located on bolt 4 and the valve seat 2, can be easily that it is spacing.
During use, enter cylinder cap from inlet hole 5 by the gas that piston motion produced behind cylinder sleeve, the impact that this moment, valve seat 2 was subjected to air-flow moves upward spring 3 compressions, and air-flow enters mounting hole 7, because by bolt seal, discharge so air communication is crossed air outlet hole 6 upper end of mounting hole 7.Because the effect of spring 3 when air-flow is discharged via cylinder cap, can only unidirectionally be flowed out, and can reversely do not returned.This cylinder head is simple, the running stability height, and assembling and maintenance are all very convenient.
Claims (3)
1, a kind of cylinder head, comprise cylinder cap, be provided with inlet hole in the bottom of described cylinder cap, it is characterized in that: the top of described inlet hole is provided with the mounting hole of perforation, valve seat is arranged in the mounting hole and is seated in the top of described inlet hole, the top seal of mounting hole is bolted with bolt, supports being provided with spring between described bolt and the valve seat; Air outlet hole is communicated with the described mounting hole and the external world.
2, cylinder head according to claim 1 is characterized in that: described air outlet hole is axially vertical with described mounting hole.
