Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1 to 3, an end face sealing structure comprises a main door 1 with an opening and closing opening and a detachable auxiliary door 2 which covers the opening and closing opening, an inner ring 3 is integrally arranged at the opening and closing opening, a ring rubber ring 4 is arranged on the inner ring 3, the inner ring 4 is hollow, when the auxiliary door 2 extrudes the rubber ring 4, an inclined slope 401 is formed on the inner ring of the rubber ring 4, and the inclined slope 401 inclines towards the center of the opening and closing opening.

The end face sealing structure realizes the maintenance and cleaning of the internal equipment of the door through the opening and closing port on the main door 1, and the opening and closing port is opened/closed through the auxiliary door 2, so the whole process is quick and convenient; through the setting of rubber circle 4, be convenient for guarantee good sealed effect, furtherly, through the sealed form of extrusion, with its whole fine sealing to with the help of the extrusion to rubber circle 4 to form slope surface 401, make follow-up stability when wasing go on.

In some embodiments, a ring groove 301 is formed at an outer ring of the inner ring 3, a snap ring 402 is integrally disposed on the rubber ring 4, and the snap ring 402 is clamped in the groove 301.

Wherein, through this recess 301 cooperation snap ring 402, realize establishing fixed effect to the card of rubber circle 4 to through the damping attribute of this rubber circle 4 self, make its whole card establish in recess 301.

In some embodiments, the surface of the rubber ring 4 away from the snap ring 402 has an inclined pressing surface 403, and the inclined pressing surface 403 is joined from the inner ring to the outer ring of the rubber ring 4. The inclined pressing surface 403 facilitates guiding and pressing, and well extrudes the inclined rubber part, so that an inclined slope 401 is formed at the position, close to the inner ring, of the rubber ring 4, water flow is conveniently guided, synchronously, cleaning liquid can be guided during cleaning, and smooth cleaning is promoted.

In some embodiments, the cross-section of the rubber ring 4 comprises a first straight line 404, a second transverse line 405, a "U" -shaped line 406 and an inclined arc line 407 joined end to end, in which cross-section there is a circular ring 408, the circular ring 408 and the inclined arc line 407 being co-circular, wherein the distance from the circular ring 408 to any edge of the cross-section is less than or equal to the difference in radius between the circular ring 408 and the inclined arc line 407.

The distance from the circular ring 408 to any edge of the cross section is smaller than or equal to the radius difference between the circular ring 408 and the inclined arc line 407, so as to ensure the overall structural strength, and the inclined arc line 407 is the inclined pressing surface 403.

In some embodiments, the distance from the intersection point between the first straight line 404 and the oblique arc line 407 to the end face of the secondary door 2 is the shortest. Through this kind of design, press and down when synchronous extrusion rubber circle 4 at supplementary door 2, what at first extrudeed is this nodical position, then realizes guiding extruded effect, guarantees the formation of slope surface 401.

In some embodiments, a ring guide ramp 302 is provided on the main door 1 at the edge of the opening and closing opening. Wherein the presence of the guide ramp 302 engages the inclined ramp 401. Generally, there are three cases:

1. the inclination degree of the guide slope surface 302 is the same as that of the inclined slope surface 401, and due to the arrangement of the mode, cleaning is facilitated, dead angles are avoided, and sealing is not facilitated.

2. The guide ramp 302 is inclined more than the inclined ramp 401, which facilitates direct guidance of the liquid elsewhere as far as possible without contact with the rubber ring 4.

3. The inclination of the guide slope 302 is less than that of the inclined slope 401, and in this way, the liquid impacts on the rubber ring 4, so that the flushing cleaning is convenient to realize, and the sealing effect is the worst.

Example two

The second embodiment is carried out on the basis of the first embodiment.

S1, pressing and clamping the rubber ring 4 on the inner ring 3; s2, extruding the rubber ring 4 through the auxiliary door 2 so that the inner ring of the rubber ring 4 forms an inclined slope 401; and S3, fixing the auxiliary door 2.

The mounting method of the end face sealing structure is simple and quick to operate.
