The spin lock cap 6 is used for extruding the sealing sleeve 7, so that the sealing sleeve 7 is deformed to be in close contact with the oil delivery pipe and the base 1, and the spin lock cap 6 applies force to the sealing sleeve 7, so that the sealing sleeve 7 is deformed to fill gaps between the sealing sleeve 7, the oil delivery pipe and the base 1, and the sealing effect is improved.

In some alternative embodiments, referring to FIGS. 1-2 and 5-6, base 1 includes an outer sleeve 11 and a boss sleeve 14 that are coupled to a steel manhole.

In this embodiment, a connecting ring groove 13 is formed on an end wall of one end of the outer sleeve 11, and the connecting ring groove 13 is communicated with the outside.

The screw connection between the screw cap 6 and the base 1 can be realized by the screw connection between the connecting ring groove 13 and the external screw sleeve 61.

In this embodiment, an inner table sleeve 15 is disposed on the inner wall of one end of the outer sleeve 11 far away from the connecting ring groove 13, and an inner ring groove 12 is disposed on one end of the inner table sleeve 15 far away from the boss sleeve 14.

The inner ring groove 12 can be connected and fastened with the extrusion sleeve 71, so that the tightness is improved.

The inner table sleeve 15 can be abutted against the extrusion sleeve 71, so that the jacking sleeve 62 is abutted against the extrusion sleeve 71 when the extrusion sleeve 71 is jacked, and the extrusion sleeve 71 is convenient to deform under force.

In some alternative embodiments, referring to figures 1-2 and 3-6, the sealing sleeve 7 comprises a compression sleeve 71 and a connection sleeve 72 fixed to one end of the compression sleeve 71.

The sealing effect is enhanced by deformation of the pressing sleeve 71 and the connection between the pressing sleeve 71 and the outer sleeve 11, and the connection between the connection sleeve 72 and the inner ring groove 12.

In this embodiment, the extrusion sleeve 71 is screwed with the inner wall of the outer sleeve 11, the connection sleeve 72 can be inserted into the inner ring groove 12, and the length of the extrusion sleeve 71 is smaller than that of the outer sleeve 11.

The extrusion sleeve 71 is screwed into the outer sleeve 11 through threads, the sealing effect between the extrusion sleeve 71 and the outer sleeve 11 is enhanced in a threaded connection mode, the oil seepage path is lengthened, the sealing effect is improved, then when the extrusion sleeve 71 is screwed into close contact with the inner table sleeve 15, the connecting sleeve 72 is also inserted into the inner ring groove 12 at the same time, when oil seeps, the seeped oil cannot directly infiltrate into a gap between the extrusion sleeve 71 and the outer sleeve 11 through the connecting sleeve 72, the seepage path is lengthened, and the sealing effect is improved.

The length of the compression sleeve 71 is less than the length of the outer sleeve 11 so that the abutment sleeve 62 will also closely engage the end wall of the outer sleeve 11 after insertion of the abutment sleeve 62 against the compression sleeve 71.

In some alternative embodiments, referring to fig. 1 and 3-5, the twist-lock cap 6 includes an outer cap barrel 63, an outer screw sleeve 61 secured to one end of the outer cap barrel 63, and a tightening sleeve 62.

By the double layer arrangement of the outer spin sleeve 61 and the tightening sleeve 62, the path of oil exudation is lengthened, and the oil does not directly infiltrate to the outside after exudation of the tightening sleeve 62.

In this embodiment, the outer rotary sleeve 61 is screwed with the connecting ring groove 13, and the length of the connecting ring groove 13 is smaller than the groove depth of the connecting ring groove 13.

The external rotation sleeve 61 is in threaded connection in the connection ring groove 13, and the length is smaller than the depth of the connection ring groove 13, so that the situation that the pressing force cannot be applied to the pressing sleeve 71 by the tightening sleeve 62 due to the fact that the external rotation sleeve 61 is too long is avoided, and the pressing sleeve 71 is deformed and sealed.

In this embodiment, the pressing sleeve 62 is screwed with the inner wall of the outer sleeve 11, and presses the pressing sleeve 71.

The knock-up sleeve 62 is also screwed with the outer sleeve 11, the knock-up sleeve 71 is fed by the screwed connection, and the provision of the screw increases the exudation path, improving the sealing effect.

When the pressing sleeve 71 is pressed against the pressing sleeve 62, the pressing sleeve 71 is deformed to further fill the gap between the oil delivery pipe and the outer sleeve 11, the gap between the threaded connection is made tighter, the sealing effect is further improved, and the connecting sleeve 72 is again pressed against the inner annular groove 12.

And through threaded connection's setting, can make quick dismantlement installation between base 1, seal cover 7 and the spin lock cap 6, can quick dismantlement change when seal cover 7 damages or needs to change, avoid glue bonding's form to lead to unable change, improved the life-span of device, improved sealed persistence and sealed effect.

The working principle and the working process of the application are as follows:

Then, the screw cap 6 is screwed into the base 1, and when the pressing sleeve 71 is pressed by the pressing sleeve 62, the pressing sleeve 71 is deformed, so that the gap between the screw cap and the oil delivery pipe is further filled, the gap between the screw cap and the outer sleeve 11 is filled, the gap between the screw connection is more compact, the sealing effect is further improved, and the connecting sleeve 72 is pressed in the inner annular groove 12 again.

Through threaded connection's setting, can make quick dismantlement installation between base 1, seal cover 7 and the spin lock cap 6, can quick dismantlement change when seal cover 7 damages or needs to change, avoid the form that glue bonded to lead to unable change, improved the life-span of device, improved sealed persistence and sealed effect.
