The connection mode of all the components of the support frame is welding.
One side of the first vertical plate, which is different from the second vertical plate, is connected with the air chamber partition plate. The first vertical plate and the second vertical plate are connected with the air chamber partition plate through a first fastening bolt group, and the first vertical plate and the air chamber partition plate are connected through a second fastening bolt group.
The sealing plate is a polytetrafluoroethylene sealing plate and has a self-lubricating effect. The second vertical plate and the sealing plate are connected through a tapping screw. The sealing plate is connected with the lower surface of the movable longitudinal beam. The self-tapping screw is used for fixing and compressing the polytetrafluoroethylene sealing plate to a specified position, the self-tapping screw is removed after the whole structure is installed, and at the moment, the polytetrafluoroethylene sealing plate is tightly attached to the lower surface of the movable longitudinal beam under the action of the spring.
Has the advantages that: compared with the prior art, the utility model, have following characteristics:
1. the polytetrafluoroethylene sealing plate has a self-lubricating effect, and has small resistance and small abrasion in the reciprocating friction contact process of the movable longitudinal beam;
2. the arrangement of the spring can ensure that the polytetrafluoroethylene plate is always in close contact with the bottom surface of the movable longitudinal beam, thereby ensuring good sealing effect;
3. the independent notches formed by the first vertical plate, the second vertical plate and the horizontal plate of the supporting frame and the self-tapping screws enable the whole sealing structure to be assembled into a whole, and replacement of spare parts is greatly facilitated.
