Description
Technical field
The utility model relates to the flexible entrucking oil filling riser seal cover cap of a kind of swing arm type.
Background technology
The main existence of the flexible entrucking oil filling riser sealing of swing arm type is following not enough in the prior art: 1) act on the stressed problem on the seal cover cap: various external force such as the low liquid level oil filling riser of oil filling riser gravity, side force, settling capacity, the mobile generation of liquid at high speed when changing when tank car loads rocks, high liquid level oil filling riser is gone here and there up and down; 2) sealing surface problem: the sealing surface of tank car mouth is the upper port plane oil proof rubber of using (the old-fashioned leads of using); Apply external force with bolt and reach air-proof condition; Tank car mouth middle part and lower position be because of being normal sealing surface, exist the sealing surface alteration of form greatly, be uneven.
Summary of the invention
The utility model provides a kind of swing arm type entrucking oil filling riser seal cover cap that stretches, and solves above-mentioned deficiency, its good sealing effect, oil filling riser good stability.
The following technical scheme of the concrete employing of the utility model:
A kind of swing arm type entrucking oil filling riser seal cover cap that stretches comprises seal cover cap, and seal cover cap is arranged on tank car mouth top; Which is provided with oil filling riser passes; It is characterized in that oil filling riser top and movable block bearing fit, hinged two folding pawls on the movable block; Tooth bar is set on the movable block cooperates with sector, the movable block upper end is connected with handle.
Be control movable block stroke, block down is set in the oil filling riser bottom.
Between oil filling riser and movable block, y-type seal ring is set, between seal cover cap and tank car mouth, the hollow sealing circle is set, seal tight.
Also be provided with fixed jaw in the seal cover cap outside.
The utility model has the advantages that:
1) when the seal cover cap pressing, the distortion of hollow sealing circle, y-type seal ring sealing contraposition is good, seals tight;
2) handle is done the time spent, and sector is opened, and further compresses the pulling force between the folding pawl of gland, and the oil filling riser of can decaying moves down rocking of generation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, the 1-handle, the 2-seal cover cap, 3-folds pawl, 4-tank car mouth, block under the 5-, 6-oil filling riser, 7-movable block, 8-sector, 9-tooth bar, 10-fixed jaw, 11-hollow sealing circle, 12-Y RunddichtringO.
The specific embodiment
As shown in Figure 1, a kind of swing arm type entrucking oil filling riser seal cover cap that stretches comprises seal cover cap 2; Seal cover cap 2 is arranged on tank car mouth 4 tops, which is provided with oil filling riser 6 and passes, oil filling riser 6 tops and movable block 7 bearing fits; Hinged two folding pawls 3 are provided with tooth bar 9 and cooperate with sector 8 on the movable block 7 on the movable block 7, and movable block 7 upper ends are connected with handle 1; Block 5 down is set below oil filling riser 6; Between oil filling riser 6 and movable block 7, y-type seal ring 12 is set, between seal cover cap 2 and tank car mouth 4, hollow sealing circle 11 is set, also be provided with fixed jaw 10 in seal cover cap 2 outsides.
