Abstract
The utility model discloses a connecting point structure of an oxygen compressor plunger rod and a guiding shaft, which comprises a plunger rod and a guiding shaft, the connection end of the plunger rod and the guiding shaft is provided with an outward convex plunger head, the plunger head is clamped inside of a groove of a guiding shaft end head, the plunger rod and a channel of a groove outlet are in a clearance fit, characterized in that, an upper spherical base and a lower spherical base are arranged between the plunger head and the groove bottom; an upper end plane of the upper spherical base is attached to a lower end plane of the plunger head, the lower end surface is an upward concave spherical surface; the upper end surface of the lower spherical base is the spherical surface attached to the lower end surface of the lower spherical base, the lower end plane of the lower spherical base is attached to the groove bottom plane. Compared to the prior art, the utility model has advantages of small friction, low noise and long service life.
Description
Technical field
The utility model relates to a kind of oxygen compressor, especially a kind of oxygen compressor plunger rod and axis of guide joint structure.
Background technique
A kind of existing oxygen compressor is arranged, its drive mechanism comprises bent axle, connecting rod, the axis of guide, plunger rod, the plunger that links to each other successively, wherein the rotation of bent axle is delivered to plunger rod by the connecting rod and the axis of guide and becomes the back and forth movement of plunger rod, plunger with the plunger rod back and forth movement and to compressing through the oxygen in the cylinder, reaches the purpose of compressed oxygen in air cavity.Wherein, the existing structure of plunger rod and axis of guide joint is: the plug that has evagination at plunger rod and axis of guide connecting end, plug is connected in the groove the inside of axis of guide termination, plunger rod cooperates with the path clearance of recess outlet, the access section is that spherical cooperates between plug upper-end surface and the groove end face, is provided with flat gasket between plug and the bottom portion of groove.During the operation of this structure, in axis of guide push, to the plunger rod applied thrust, and then the oxygen that promotes in the plunger countercylinder compresses the axis of guide by flat gasket; When the axis of guide reclaims, cooperate with spherical clamping between the groove end face by the plug upper-end surface, drive plunger rod and fall after rise and reset.So just cause on the axis of guide, to push away and to eliminate in the process, make that friction phenomenon is serious between plunger and the cylinder wall, and then make this existing structure have defectives such as noise is big, the life-span is short because of bent axle rotates the circumferential oscillatory forces of bringing.
The model utility content
Technical problem to be solved in the utility model is in order to overcome the prior art above shortcomings, and provides a kind of the reduction to rub between plunger and the cylinder wall, and then reduces noise, increases the oxygen compressor plunger rod and the axis of guide joint structure in life-span.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of oxygen compressor plunger rod and axis of guide joint structure, comprise plunger rod, the axis of guide, plunger rod and axis of guide connecting end have the plug of evagination, and plug is connected in the groove the inside of axis of guide termination, and plunger rod cooperates with the path clearance of recess outlet; Its characteristics are also to be provided with between described plug and the bottom portion of groove spheric seat and following spheric seat; Transverse plane applying under Transverse plane and the plug on the last spheric seat, the lower end surface is the spherical of fovea superior; Following spheric seat upper-end surface is the spherical of fitting with last spheric seat lower end surface, and under the following spheric seat fit in Transverse plane and bottom portion of groove plane.
In axis of guide push, the axis of guide, and then promoted the interior oxygen of plunger countercylinder and compresses the plunger rod applied thrust by last spheric seat and following spheric seat when the utility model used; When the axis of guide reclaims, cooperate with clamping between the groove end face by the plug upper-end surface, drive plunger rod and fall after rise and reset.Like this when the axis of guide is released, owing to have the spherical of a cooperation between last spheric seat and the following spheric seat, can eliminate bent axle like this by the skew between the spherical and be delivered to circumferential pendulum power on the axis of guide, and then the frictional impact between reduction plunger and the cylinder wall, reduce noise, increased working life.
So than prior art, it is little to the utlity model has friction, and noise is low, the advantage that the life-span is long.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
During concrete enforcement, as shown in Figure 1, a kind of oxygen compressor plunger rod and axis of guide joint structure, comprise plunger rod 1, the axis of guide 2, plunger rod 1 and the axis of guide 2 connecting ends have the plug 3 of evagination, plug 3 is connected in groove 4 the insides of the axis of guide 2 terminations, passage 5 Spielpassung of plunger rod 1 and groove 4 outlets; Wherein, also be provided with spheric seat 6 and following spheric seat 7 between described plug 3 and groove 4 bottoms; 3 times Transverse planes of Transverse plane and plug are fitted on the last spheric seat 6, and the lower end surface is the spherical of fovea superior; Following spheric seat 7 upper-end surfaces are the spherical of fitting with last spheric seat 6 lower end surfaces, and 7 times Transverse planes of following spheric seat and groove 4 base plane are fitted.
During concrete enforcement, described groove 4 upper end-hole can adopt the screw thread gland 8 that spins, gland 8 forms clamping to plug 3 after groove 4 connects, gland 8 middle parts are the passage 5 that cooperates with plunger rod 1, groove 4 inside are filled with lubricant oil, all leave the gap between last spheric seat 6 and following spheric seat 7 and groove 4 sidewalls, thereby the feasible spheric seat 6 of going up all can be in the pendulum power that is mingled with in the lubricated elimination of the horizontal slip down thrust transmission of lubricant oil with following spheric seat 7.It is little to make that the utility model possesses friction, and noise is low, the advantage that the life-span is long.
