Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of , but not all embodiments.

Please refer to fig. 1-4, the utility model provides an kinds of embodiments are seal structure convenient to dismantle installation, including seal 1, the screw rod 2 has been inserted in seal 1, and cup jointed connecting block 3 on the screw rod 2, and the outside fixed welding of connecting block 3 has a backup pad 4, sealing washer 5 has been inlayed to the downside of backup pad 4, the pot head of screw rod 2 is equipped with knob 6, the middle part of knob 6 begins to have the through thread hole, and the inboard size of screw hole is the same with the outside size of screw rod 2, knob 6 sets up to rotatory screw thread formula elevation structure through screw rod 2, through twisting knob 6, make knob 6 rise or descend along screw rod 2, thereby realize the compaction or loosen connecting block 3.

The lower end of the screw rod 2 is fixedly sleeved with a bearing 7, articulated shafts 8 are fixedly welded on the outer side of the bearing 7, four groups of articulated shafts 8 are arranged on the articulated shafts 8, the four groups of articulated shafts 8 are fixedly distributed on the outer side of the bearing 7 in a circular array structure, the four groups of articulated shafts 8 are all arranged in a rotating structure to ensure that the rotation of the four groups of articulated shafts 8 is not influenced when the screw rod 2 rotates, a limiting block 9 is fixedly arranged on the lower side of the articulated shaft 8, a baffle plate 10 is sleeved on the articulated shaft 8, a sealing gasket 11 is embedded on the upper side of the baffle plate 10, the four groups of baffle plates 10 are arranged on the baffle plate 10, the baffle plate 10 can be unfolded or folded along the screw rod 2 through the rotation of the baffle plate 10, salient points are uniformly distributed on the sealing gasket 11 and the sealing ring 5, and the contact areas of the lower edge and the upper edge of, the lower edge and the upper edge of the opening of the sealing body 1 are in a sealing state, so that the sealing performance is greatly improved.

Be connected with elastic cord 12 between baffle 10 and the connecting block 3, the downside fixed mounting of baffle 10 has the sealed piece of rubber 13, and the sealed piece of rubber 13 sets up to bowl form structure, and the sealed piece of rubber 13 along the central line position fixed mounting of screw rod 2 at the downside of four group's baffles 10 to in sealing 1 open-ended downside.

The working principle is as follows: during installation, the four groups of baffles 10 are retracted around the screw rod 2 through the hinge shaft 8, the screw rod 2 and the baffles 10 in a vertical state are extended into the opening of the sealing body 1, the uppermost horizontal line of the baffles 10 is lower than the horizontal line of the lower side of the opening of the sealing body 1, then, the four groups of baffles 10 are unfolded by utilizing the flexible tension of the bowl-shaped rubber sealing block 13 and matching the gravity of the baffles 10, and the four groups of baffles 10 are blocked by the limiting blocks 9 in the unfolding process, so that the four groups of baffles 10 and the screw rod 2 are kept in a vertical state;

then, the screw rod 2 is pulled upwards, so that the four groups of baffles 10 and the sealing gaskets 11 are tightly attached to the edge of the lower side of the opening of the sealing body 1, the supporting plate 4 and the sealing ring 5 are tightly attached to the edge of the upper side of the opening of the sealing body 1 along the screw rod 2 through the connecting block 3, and finally the knob 6 is screwed, so that the knob 6 descends along the screw rod 2 until the connecting block 3 is tightly pressed, and the installation is completed;

at this time, the lower edge and the upper edge of the opening of the sealing body 1 are in a sealing state by matching with the bowl-shaped rubber sealing block 13, so that the sealing property is improved;

during the dismantlement, twist knob 6 and move upward to with connecting block 3 along screw rod 2 rebound, make connecting block 3 pass through elastic cord 12, the pulling baffle 10 replies, finally, with screw rod 2 and reply keep the baffle 10 of vertical state to take out from the opening of seal 1 can.

It will thus be seen that the present invention is illustrative and not restrictive, and the scope of the invention is defined by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
