Description
Technical field
It the utility model is related to air compression equipment technology field, more particularly to a kind of oilless air compressor.
Background technology
Currently used oilless air compressor design pressure is at 7-8 kilograms, and national correlation department is to New energy electric within 2017
Logo standard is modified, and the oilless air compressor pressure criteria that electric automobile uses is brought up to 10-12 public affairs by amended standard
Jin, existing oilless air compressor include cylinder, and top is the connecting rod of T-shaped, and the periphery of connecting rod top disk is inverted cone surface, is also wrapped
The leather cup that connecting rod top is arranged on by means of leather cup pressing plate is included, leather cup uses as piston, and connecting rod drives leather cup past in cylinder
Cylinder inner cavity is isolated into two cavitys by multiple motion, the leather cup of existing oilless air compressor, and upper chamber is compression chamber, and under
Portion's cavity is free cavity, although leather cup edge coordinates with cylinder inner wall sealing, in the oilless air compressor course of work, and free chamber
Interior dust and other impurities are easily adhered between cylinder and leather cup, leather cup and cylinder inner wall serious wear, or even can stab skin
Bowl, causes piston effect to fail；Still further aspect, in order to give full play to the piston effect of leather cup, leather cup uses flexible material, and
Connecting rod and leather cup gland are rigid material, in order to avoid influenceing with cylinder the sealing property of leather cup, leather cup not coaxial because of connecting rod
There must be gap between leather cup gland, the purpose for setting gap is to ensure leather cup within the specific limits up and down freely
Motion, it is ensured that under any motion state, the circumference of leather cup can with cylinder inner wall palette, still, because the gap
In the presence of oilless air compressor is during inflating, and the gases at high pressure in working chamber will produce reverse pressure to leather cup, in high pressure
In the presence of gas, leather cup expands outwardly, and the bigger leather cup of pressure and cylinder friction will be bigger, easily produce high temperature, influence skin
The service life of bowl, still further aspect, frequently switches, leather cup is easily lost under high pressure and low-pressure state（Referring to accompanying drawing 2）.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of oilless air compressor, and on connecting rod top, installation annular is close
Seal, reversely sealing is formed on the downside of leather cup, prevents dust from entering the rubbing surface of leather cup and cylinder, between leather cup and leather cup pressing plate
Gap in fill high temperature resistant elastic gum, do not influenceing between leather cup and leather cup pressing plate on the premise of relative motion, to prevent leather cup
Excessive deformation.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of oilless air compressor, including cylinder
Body, connecting rod, leather cup and leather cup pressing plate, high temperature resistant elastic gum, the company are filled in the gap between leather cup and the leather cup pressing plate
Bar top is set with O-ring seal, and edge is fitted in below leather cup pressing plate in O-ring seal.
The connecting rod is the T-shaped revolving body in section, and its top disc circumference is the face of cylinder, and the O-ring seal is disconnected
The L-shaped revolving body of face shape, its outer wall and cylinder inner wall palette.
The connecting rod top sets circular groove, and leather cup pressing plate lower surface sets the round boss chimeric with circular groove,
Leather cup pressing plate is fixedly mounted on connecting rod top by means of screw.
It is using beneficial effect caused by above-mentioned technical proposal：By installing O-ring seal on connecting rod top,
Reversely sealing is formed on the downside of leather cup, on the premise of original structure radiating effect is not influenceed, prevents dust from entering leather cup and cylinder
Rubbing surface, effectively extend leather cup service life, pass through in the gap between leather cup and leather cup pressing plate fill high temperature resistant elasticity
Glue, do not influenceing between leather cup and leather cup pressing plate on the premise of relative motion, to prevent leather cup excessive deformation, avoiding increase from rubbing
Power, prevent the high temperature that rubs.

Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new
Type can also be different from other manner described here using other to be implemented, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of new intension, therefore the utility model is not limited by following public specific embodiment.
As shown in figure 1, the utility model discloses a kind of oilless air compressor, including cylinder body, connecting rod 5, leather cup and leather cup pressure
Plate 3, it is characterised in that：High temperature resistant elastic gum 6, the top of connecting rod 5 are filled in gap between leather cup and the leather cup pressing plate 3
O-ring seal 7 is set with, edge is fitted in the lower section of leather cup pressing plate 3 in O-ring seal 7；The connecting rod 5 is the T-shaped revolution in section
Body, its top disc circumference are the face of cylinder, and the O-ring seal 7 is the L-shaped revolving body of section configuration, its outer wall and cylinder
1 inner wall sealing is bonded；The top of connecting rod 5 sets circular groove, and the lower surface of leather cup pressing plate 3 sets the circle chimeric with circular groove
Shape boss, leather cup pressing plate 3 are fixedly mounted on the top of connecting rod 5 by means of screw 2.
During concrete application, come seal friction area in the O-ring seal of one similar leather cup of the following left-hand thread of leather cup,
For principle similar to dust ring, and can plays sealing function under the premise of original structure good heat dissipation is not influenceed, and reduces abrasion；In leather cup and pressure
High temperature resistant elastic gum or other high temperature resistant elastic materials are filled between lid in gap, filler properly only has natural resiliency pressure because elastic
Power, such gases at high pressure would not produce pressure to leather cup, and such one is leather cup excessive deformation when solving the problems, such as high pressure, and two
It is to solve the problems, such as that friction is big, third, reducing the high temperature problem that friction belt is come.
In a word, the utility model forms reversely sealing by installing O-ring seal on connecting rod top on the downside of leather cup,
On the premise of not influenceing original structure radiating effect, prevent dust from entering the rubbing surface of leather cup and cylinder, effectively extending leather cup makes
With the life-span, by filling high temperature resistant elastic gum in the gap between leather cup and leather cup pressing plate, leather cup and leather cup pressure are not being influenceed
Between plate on the premise of relative motion, leather cup excessive deformation is prevented, avoids increasing friction force, prevent the high temperature that rubs.
