Joint spare 2 sets up to two when can making joint spare 2 and pipeline 5 reliably be connected, the installation of joint spare 2 of being convenient for. However, the number of the clips 2 is not limited to the present invention, and for example, three, four or five clips 2 may be provided.

In order to more reliably fix the pipeline 5, as shown in fig. 1 and fig. 2, two first clamping grooves 6 are formed in the inner wall of the first clamp body 1 at intervals, the two first clamping grooves 6 in the first clamp body 1 are respectively located at two ends of the sealing ring 4, two first clamping grooves 6 in one-to-one correspondence with the two first clamping grooves 6 in the first clamp body 1 are formed in the inner wall of the second clamp body 3, and each first clamping groove 6 is internally and respectively clamped with one clamping piece 2. The two pipes 5 connected by the pipe direct joint in the embodiment can be reliably fixed.

As shown in fig. 4, the sealing ring 4 includes an annular sealing body 41 and a limit protruding ring 43, the inner wall of the sealing body 41 is provided with the limit protruding ring 43, and the inner diameter of the limit protruding ring 43 is smaller than the outer diameter of the connected pipeline 5. Specifically, second draw-in groove 7 has all been seted up on the inner wall of first clamp body 1 and second clamp body 3, during connecting tube 5, 4 joints of sealing washer are in two second draw-in grooves 7, and spacing bulge loop 43 joints are between two pipelines 5 that will connect, and pipeline 5 that spacing bulge loop 43 can carry out the axial spacing to can improve sealed effect.

In this embodiment, the inner wall at seal 41 both ends all is connected with sealing ring 44, and the one end that sealing ring 44 kept away from seal 41 all sets up to the middle part slope of sealing washer 4, and the setting of sealing ring 44 can make sealing washer 4 and pipeline 5 closely laminate, improves sealed effect, can also be convenient for pipeline 5 insert in sealing washer 4.

In order to increase the connection strength between the limit protruding ring 43 and the sealing body 41, the sealing ring 4 further includes an annular protruding portion 42, an outer wall of the protruding portion 42 is connected to an inner wall of the sealing body 41, and an inner wall of the protruding portion 42 is connected to an outer wall of the limit protruding ring 43. It is understood that the length of the boss 42 in the direction of the central axis of the seal ring 4 is greater than the length of the stopper ring 43, and the stopper ring 43 is provided in the middle of the boss 42. The convex portion 42 serves as a transition, and the connection strength of the stopper convex ring 43 can be improved.

In another embodiment, as shown in fig. 5, the inner wall of sealing element 41 has a corrugated shape that is distributed along the central axis direction of sealing element 41, and the sealing effect of sealing element 41 can be improved by providing the convex portions and the concave portions on the inner wall of sealing element 41.

As shown in fig. 6, one side of the first band body 1 is hinged to one side of the second band body 3, which can facilitate the connection of the first band body 1 and the second band body 3. Specifically, a first connection ring 12 is disposed on one side of the first band body 1, a second connection ring 32 is disposed on one side of the second band body 3 connected to the first band body 1, and the first band body 1 and the second band body 3 are hinged by a pin penetrating through the first connection ring 12 and the second connection ring 32.
