Description
Technical Field
The utility model relates to a sealed blanking cover belongs to waterproof sealing technical field.
Background
The blanking cover is a device for plugging the hole, has higher waterproof sealing requirement, consequently in prior art, often uses blanking cover and O type sealing washer together, generally sets up the lower sealed face at the blanking cover with O type sealing washer, and when the blanking cover screwed through the screw, O type sealing washer also was compressed tightly in step, plays better waterproof sealing effect. However, in actual operation, the O-ring often expands outwards to slip to the outside of the plug when the plug is pressed by rotation, and cannot achieve the effect, and if the press is not tight, the O-ring cannot expand outwards to slip, but cannot achieve the sealing effect. Meanwhile, the O-shaped sealing ring can generate cracks due to drying after being used for a long time, and finally the sealing effect is lost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sealed blanking cover to strengthen the sealed effect of blanking cover.
The technical scheme is as follows:
a sealing plug cover comprises a plug cover body and an O-shaped sealing ring, wherein the cross section of the plug cover body is in an inverted T shape and is formed by connecting a truncated cone-shaped sealing part and a cylindrical combining part, and the combining part is positioned in the center of the sealing part; the side of the joint part which is not connected with the sealing part is provided with a hexagonal blind hole, the side of the sealing part facing the joint part is a press-fitting surface, the other side of the sealing part is a back surface, the press-fitting surface surrounds the joint part and is provided with a circle of annular grooves, the O-shaped sealing ring is embedded into the annular grooves, the width of the annular grooves is consistent with the diameter of the O-shaped sealing ring, the side surface of the sealing part is provided with more than one oil injection hole, and the oil injection holes are communicated.
Furthermore, the periphery of the combining part is provided with inverted sawtooth-shaped threads, and the thread specification is M22 × 1.5.
Further, the cross section of the annular groove is isosceles trapezoid, and the upper foot of the trapezoid is 120 degrees.
Furthermore, a hexagonal blind hole is formed in the back face of the sealing portion.
Further, the oil injection holes are six and are spaced by 60 degrees in pairs.
Has the advantages that:
the utility model discloses a set up the ring channel that can imbed O type sealing washer at the blanking cover body, effectively fixed the position of O type sealing washer, avoided its inflation slippage in sealed process to through setting up the oil filler point, guarantee better sealing performance, improve the life of O type sealing washer through regular injection lubricating oil, simple structure, low cost.
Drawings
Fig. 1 is a schematic cross-sectional view of the plug body of the present invention;
fig. 2 is a schematic cross-sectional view of the O-ring embedded in the plug body according to the present invention;

wherein: the sealing cover comprises a blocking cover body 1, a combination part 2, a sealing part 3, an O-shaped sealing ring 4, an annular groove 5 and an oil filling hole 6.
Detailed Description
The present invention will be described in detail with reference to the following drawings and specific embodiments:
a sealing closure as shown in fig. 1 to 3, comprising a closure body 1 and an O-ring 4, wherein the cross-section of the closure body 1 is inverted T-shaped, and is formed by connecting a truncated cone-shaped sealing portion 3 and a cylindrical joint portion 2, and the joint portion 2 is located at the center of the sealing portion 3; the one side that joint portion 2 does not link to each other with sealing portion 3 has opened a hexagonal blind hole, and the one side of sealing portion 3 towards joint portion 2 is the pressure equipment face, and the another side is the back, and the pressure equipment face is opened around joint portion 2 has a round ring channel 5, and O type sealing washer 4 embedding ring channel 5, and the width of ring channel 5 is unanimous with O type sealing washer 4 diameter, and the side of sealing portion 3 has the oil filler point 6 of seting up more than one, and oil filler point 6 lets in ring channel 5.
The periphery of the combining part is provided with inverted sawtooth-shaped threads, and the thread specification is M22 × 1.5.
The section of the annular groove 5 is isosceles trapezoid, and the upper foot of the trapezoid is 120 degrees.
The back of the sealing part 3 is provided with a hexagonal blind hole.
The oil filling holes 6 are six and are spaced by 60 degrees in pairs.
The first embodiment is as follows: choose the O type sealing washer that the line footpath is 3 millimeters for use, the cover is on the joint portion of blanking cap body, fill in the hole that needs to seal with the joint portion of blanking cap body, insert the hexagonal blind hole at the sealing back with the hexagonal spanner, carry out the rotation and compress tightly, O type sealing washer is impressed the ring channel, and fixed by the ring channel, can select this moment to pour into lubricating oil into in the oiling hole when continuing the rotation, guarantee better sealing performance and improve the life of O type sealing washer, the rotation compresses tightly the back and accomplishes the sealing to the hole.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and scope of the present invention are intended to be included therein.
