The medial surface fixed seal connection of the lateral surface of the first end of adapter and second butt tube, the second end of the interior butt tube
It is arranged in first butt tube, the medial surface of first butt tube is provided with ring type deep trough, and the ring type deep trough passes through
Stomata and ft connection, the outer end of the stomata are provided with air valve, and the air valve is connected by tracheae with the air pump gas circuit, institute
The the second end lateral surface for stating interior butt tube is provided with annular shallow slot, and India rubber sealing ring is provided with the annular shallow slot.
Specifically, the distance between inner and butt end of first butt tube of the ring type deep trough is less than in described
The distance between second end of butt tube and the butt end of second butt tube, the width of the annular shallow slot is more than the ring
The width of shape deep trouth, the inner of the annular shallow slot are located at the inner inner side of the ring type deep trough, the outer end of the annular shallow slot
Positioned at the outside of the outer end of the ring type deep trough, the both ends of India rubber sealing ring both ends with the annular shallow slot respectively
It is fixedly connected, the thickness of the India rubber sealing ring is not more than the depth of the annular shallow slot.
Preferably, the external diameter of the interior butt tube is equal to the internal diameter of first butt tube.
The beneficial effects of the utility model are：
The utility model chemical tube docking facilities in the first butt tube by setting ring type deep trough, and on interior butt tube
India rubber sealing ring is set, taken out ring type deep trough for negative pressure by air pump, so as to realize the first butt tube and the second butt tube
Between connection；By injecting air into ring type deep trough, it is not negative pressure to make ring type deep trough, is easy to the first butt tube and second pair
Separation between adapter.
Brief description of the drawings
Fig. 1 is the structural representation of chemical tube docking facilities described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of chemical tube docking facilities of the utility model, including it is the first butt tube 1, the second butt tube 2, interior
Butt tube 3 and air pump, the medial surface fixed seal connection of the lateral surface of the first end of interior butt tube 3 and the second butt tube 2 are interior right
Second end of adapter 3 is arranged in the first butt tube 1, and the medial surface of the first butt tube 1 is provided with ring type deep trough 4, ring type deep trough 4
By stomata 5 and ft connection, the outer end of stomata 5 is provided with air valve 6, and air valve 6 is connected by tracheae with air pump gas circuit, interior docking
Second end lateral surface of pipe 3 is provided with annular shallow slot 7, and India rubber sealing ring 8 is provided with annular shallow slot 7, ring type deep trough 4
The distance between inner butt end with the first butt tube 1 is less than the second end and the butt end of the second butt tube 2 of interior butt tube 3
The distance between, the width of annular shallow slot 7 is more than the width of ring type deep trough 4, and the inner of annular shallow slot 7 is located in ring type deep trough 4
The inner side at end, the outer end of annular shallow slot 7 are located at the outside of the outer end of ring type deep trough 4, the both ends of India rubber sealing ring 8 respectively with
The both ends of annular shallow slot 7 are fixedly connected, and the thickness of India rubber sealing ring 8 is not more than the depth of annular shallow slot 7, interior butt tube 3
External diameter be equal to the first butt tube 1 internal diameter.
A kind of operation principle of chemical tube docking facilities of the utility model is as follows：
When needing connection, the first butt tube 1 is aligned with the butt end of the second butt tube 2, while make interior butt tube 3
Second end is inserted into the first butt tube 1 so that the interface of the first butt tube 1 is bonded with the interface of the second butt tube 2, so
A part out is extracted the air in ring type deep trough 4 by air pump afterwards so that ring type deep trough 4 is in negative pressure state, and closes air valve
6, the now elastic deformation under the influence of air pressure of India rubber sealing ring 8, and be bonded with the edge of ring type deep trough 4, realize sealing
With fixation.
When needing to take apart, air valve 6 is opened, its air is entered in ring type deep trough 4 so that ring type deep trough 4 is not at
Negative pressure state, India rubber sealing ring 8 separate with ring type deep trough 4, so that the first butt tube 1 and the second butt tube 2 separate.
The technical solution of the utility model is not limited to the limitation of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, each falls within the scope of protection of the utility model.
