The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1, a kind of cylinder head of 3D printing, the edge of cylinder 2 is provided with a circle groove 201,1 edge of cylinder head
Two circles and the protrusion 101 of groove 201 corresponding first and the second protrusion 102 are provided with, the first protrusion 101 and the second protrusion 102 are flat
Row is set.It is provided with the first protrusion 101 and the second protrusion 102 in cylinder head 1 between first protrusion 101 and the second protrusion 102
Between the gas passage 103 that is in communication with the outside of space, gas passage 103 is used for after cylinder head 1 is installed to above cylinder 2,
Nitrogen is filled in space between first protrusion 101 and the second protrusion 102, nitrogen can play the role of sealing.
As shown in Figure 1, the first protrusion 101 and the second protrusion 102, in groove 201, the first protrusion 101 and second is raised
The third protrusion 202 extended towards cylinder head 1 is provided with 201 bottom surface of groove between 102, third protrusion 202 is by groove 201
It is divided into the first groove and the second groove, passes through horizontal stroke between the first protrusion 101 and the first groove, the second protrusion 102 and the second groove
Section is sealed for U-shaped sealing ring 3.Some sawtooth 301 are provided with the sealing ring 3 of 201 bottom end face of groove, it is small
And close sawtooth 301 can more improve sealing effect.Due to cylinder 2 and cylinder head 1 sealing surface not in one plane, so close
Seal 3 also can be there are turning, and sealing ring of the prior art 3 easily produces wedge angle around the corner, so the sealing of corner
It is not tight.As shown in Fig. 2, the bottom of the sealing ring 3 at the corner location of the utility model is provided with two semi-cylindrical hills 302,
