The during operation, after clamp 2 fastens, rotatable hollow screw 21 makes hollow screw 21 outwards remove, and hollow screw 21 removes and will stimulate lug 14, makes the joint body 1 that links firmly with lug 14 outwards stimulate to make 1 inner wall of joint body outwards sunken and the pit appears, the pit is sealed glue accumulation department, after sealed glue has dried, will make pit department easily form sealing layer 4, be favorable to the sealing connection between stainless steel sealing tube joint and the stainless steel pipe 3.
A push rod 22 is arranged in the hollow screw 21; one end of the push rod 22 penetrates through the bump 14 and is fixedly connected with the joint body 1, and the length of the push rod 22 is greater than or equal to that of the hollow screw 21. During operation, after rotating hollow screw 21 and making the 1 inner wall of joint body outside sunken and appear the pit, pit department gathers sealed glue, and at this moment, manual round trip promotes push rod 22, extrudees the pit department of joint body 1 with push rod 22, makes sealed glue of pit department can spread other positions to make sealed scope increase, and then improve sealed effect of gluing.
One end part of the hollow screw 21 is provided with a rubber elastic sheet 23; the middle part of the rubber elastic sheet 23 is abutted against the end part of the push rod 22. The during operation, only need stimulate push rod 22 backward, rubber shrapnel 23 atress is elongated, loosen push rod 22 back, push rod 22 is under rubber shrapnel 23's effect, push rod 22 is popped out and pushes up in the pit department that connects body 1, thereby it is extruded the diffusion to easily make sealed glue that connects 1 pit department, push rod 22 is more fast by the speed that the staff promoted push rod 22 of comparing of the speed that rubber shrapnel 23 was stretched out, thereby, it is better than direct round trip promotion push rod 22 and extrude 1 pit department of joint body to stretch out with rubber shrapnel 23, comparatively labour saving and time saving.
The specific working process is as follows:
two stainless steel pipes 3 are connected to the joint body 1, two stainless steel pipes 3 with different diameters can be connected through a first thread and a second thread 113, after the stainless steel pipe 3 is connected with the joint body 1 by the screw thread, the stainless steel pipe 3 and the joint body 1 are rotated again according to the screw thread direction, so that the joint body 1 between the adjacent supporting blocks 11 is wrinkled, thereby shortening the distance between two adjacent supporting blocks 11, continuously rotating the stainless steel pipe 3 and the joint body 1, the convex part 111 and the concave part 112 between the adjacent supporting blocks 11 can be inserted and matched to realize the sealing and fastening between the joint body 1 and the stainless steel pipe 3 again, and simultaneously, the clamp 2 is fastened through the bolt connecting piece 24, in the fastening process of the clamp 2, the two adjacent supporting blocks 11 can be inserted more firmly, and the two adjacent stainless steel pipes 3 can be connected in a sealing and fastening manner;
when the stainless steel pipe 3 and the joint body 1 are rotated in the thread direction, the joint body 1 between the adjacent supporting blocks 11 generates convex wrinkles, the rigid needle 12 can avoid the convex part 111 which is embedded into the concave part 112 after the joint body 1 is wrinkled, and when the clamp 2 is fastened by the bolt connecting piece 24, the clamp 2 extrudes the wrinkled joint body 1, the rigid needle 12 is inserted into the convex part 111, so that waterproof glue in the supporting blocks 11 flows out to adhere and fasten four gaps and form the sealing layer 4; when the clamp 2 is fastened by the bolt connecting piece 24, the cavity 13 is extruded, and the gas in the cavity 13 overflows and is blown to the waterproof glue along the pore, so that the waterproof glue is diffused and can be quickly hardened and solidified, and the fastening connection between the joint body 1 and the stainless steel pipe 3 is facilitated; after the clamp 2 is fastened, the hollow screw 21 can be rotated to enable the hollow screw 21 to move outwards, the hollow screw 21 moves to pull the projection 14, so that the joint body 1 fixedly connected with the projection 14 is pulled outwards, the inner wall of the joint body 1 is sunken outwards to form a pit, the pit is a sealant accumulation part, and after sealant is dried, the pit is easy to form a sealing layer 4, so that the sealing connection between the stainless steel sealing pipe joint and the stainless steel pipe 3 is facilitated; need stimulate the push rod 22 backward, rubber shrapnel 23 atress is elongated, loosen push rod 22 back, push rod 22 is under rubber shrapnel 23's effect, push rod 22 is popped out and pushes up in the pit department that connects body 1 to the light sealed glue that makes 1 pit department of joint body is extruded the diffusion, thereby makes sealed glue of pit department can diffuse other positions, thereby makes the sealed scope increase of gluing, and then improves sealed effect of gluing.
While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
