Abstract
The utility model relates to an interface device of a rotary drum. The interface device of the rotary drum comprises an interface and a breather pipe passing through the interface; a pressure plate is arranged at the upper part of the interface; the pressure plate comprises an upper plate and a lower plate which are movably connected; a spring is arranged between the upper plate and the lower plate, and a circle of sealing rings fixed on the lower plate are arranged at the external upper part of the interface. According to the interface device of the rotary drum, the interface and a barrel opening can be prevented from becoming flexible, and the dropping phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of interface device, is specifically related to a kind of drum barrel interface device.
Background technique
The drum barrel interface of usefulness is generally screw type interface now, all needs manual docking when using at every turn, and screw thread is often stubborn not tight, and sealing is poor, causes easily the distortion of bung, complicated operation, time-consuming strength.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of drum barrel interface device, this device solves the sealing that causes of interface regular screw threads poor, the problem of complicated operation.
Technological scheme of the present invention is as follows:
A kind of drum barrel interface device, its specialization are, comprise interface and the breathing pipe that passes interface, described interface top is provided with pressing plate, described pressing plate comprises upper plate and the lower plate of flexible connection, is provided with spring between upper plate and the lower plate, and the interface outer upper is provided with one and encloses the seal ring that is fixed on the lower plate.
Further, described interface middle and lower part is provided with a circle outside thread.
The drum barrel interface device that the utility model provides is provided with the pressing plate with spring, can increase the pressure between interface and the bung when interface and bung screw, prevents from becoming flexible, and is provided with simultaneously seal ring, has stopped the generation of weeping.The screw thread of interface only is provided with a circle screw thread in the middle and lower part of interface, can avoid causing the distortion of bung in the process of turning.
Description of drawings
Fig. 1 is the structural representation of drum barrel interface device.
1. breathing pipe; 2. pressing plate; 3. seal ring; 4. interface; 5. outside thread; 6. spring; 7. upper plate; 8. lower plate.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The drum barrel interface device that the utility model provides, comprise interface 4 and the breathing pipe 1 that passes interface 4, described interface 4 tops are provided with pressing plate 2, described pressing plate 2 comprises upper plate 7 and the lower plate 8 of flexible connection, be provided with spring 6 between upper plate 7 and the lower plate 8, interface 4 outer upper are provided with one and enclose the seal ring 3 that is fixed on the lower plate 8, and described interface 4 middle and lower parts are provided with a circle outside thread 5.
During use, downward threaded together, lower plate is pressed to the spring energy of bung upper limb by spring, has avoided the generation of weeping, also is not easy to become flexible between bung and the interface simultaneously.
