BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a partial cross-sectional view of the axonometric drawing of the utility model. DETAILED DESCRIPTION

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0017] like Figure 1 As shown, the utility model PE steel belt wrapped pipe includes a pipe body 10 and a connecting ring 11. The ends of the two pipe bodies 10 are arranged opposite to each other and are connected and fixed by the connecting ring 11. A plurality of first arc strips 21 are evenly fixed circumferentially on the outer surface of the end of the pipe body 10, and a corresponding second arc strip 22 is evenly fixed circumferentially on the inner surface of the end of the connecting ring 11. The plurality of second arc strips 22 are arranged in two groups along the axial direction of the connecting ring 11, and the first arc strip 21 and the second arc strip 22 can be clamped with each other to connect and fix the two pipe bodies 10.

[0018] The utility model connects and fixes the two tube bodies 10 by placing the end of the tube body 10 inside the end of the connecting ring 11 and making the first arc strip 21 and the second arc strip 22 mutually clamped; when disassembling, only the first arc strip 21 and the second arc strip 22 need to be separated from each other to disassemble the tube body 10 and the connecting ring 11, which has a simple structure and is easy to operate during the installation and disassembly process.

[0019] The number of the first arc-shaped bars 21 and the second arc-shaped bars 22 is the same and they are arranged at intervals, and a second arc-shaped bar 22 or a first arc-shaped bar can be accommodated between two first arc-shaped bars 21 or two second arc-shaped bars 22 .

[0020] Preferably, the end surface of the first arc strip 21 away from the connecting ring 11 is provided with a first inclined surface 23, and the end surface of the second arc strip 22 away from the tube body 10 is provided with a second inclined surface 24. The first inclined surface 23 and the second inclined surface 24 can contact and have the same inclined direction.

[0021] The utility model places the end of the tube body 10 in the end of the connecting ring 11, and relatively rotates the tube body 10 and the connecting ring 11, so that the first inclined surface 23 of the first arc strip 21 and the second inclined surface 24 of the second arc strip 22 are mutually engaged, so as to connect and fix the two tube bodies 10; when disassembling, it is only necessary to rotate the tube body 10 and the connecting ring 11 in the opposite direction, so that the first arc strip 21 and the second arc strip 22 are separated from each other, and the tube body 10 and the connecting ring 11 can be disassembled.

[0022] Preferably, the inclination direction of the first inclined surface 23 and the second inclined surface 24 is the same as the direction in which the tube body 10 is screwed into the connecting ring 11 .

[0023] The directions in which the two tube bodies 10 are screwed into the connecting ring 11 may be the same or different, but it is necessary to ensure that the inclination direction of the first inclined surface 23 and the second inclined surface 24 is the same as the screwing direction; and when the two tube bodies 10 are screwed into the connecting ring 11 in the same direction, only the connecting ring 11 can be rotated to keep the two tube bodies 10 stationary, thereby facilitating installation.

[0024] Preferably, a plurality of tooth grooves 25 are evenly formed on the end surface of the tube body 10 in the circumferential direction, and the first arc strip 21 and the second arc strip 22 can be engaged with each other, and the tooth grooves 25 on the end surfaces of the two tube bodies 10 are engaged with each other.

[0025] The utility model places the end of the tube body 10 in the end of the connecting ring 11, and relatively rotates the tube body 10 and the connecting ring 11, so that the first inclined surface 23 of the first arc strip 21 and the second inclined surface 24 of the second arc strip 22 are mutually engaged, and at the same time, the multiple tooth grooves 25 on the end surfaces of the two tube bodies 10 are mutually engaged to play a locking role, so as to improve the connection stability between the tube body 10 and the connecting ring 11, and between the two tube bodies 10, and avoid connection failure; when disassembling, it is only necessary to rotate the tube body 10 and the connecting ring 11 in the opposite direction, so that the multiple tooth grooves 25 on the end surfaces of the two tube bodies 10 are separated from each other, and the first arc strip 21 and the second arc strip 22 are separated from each other, and the tube body 10 and the connecting ring 11 can be disassembled.

[0026] Preferably, the tooth groove 25 includes a third inclined surface 26 and a fourth inclined surface 27 with opposite inclined directions, and the third inclined surface 26 and the first inclined surface 23 have the same inclined direction.

[0027] The third inclined surface 26 and the fourth inclined surface 27 have the same inclination.

[0028] Preferably, the inclination of the third inclined surface 26 is smaller than that of the fourth inclined surface 27 .

[0029] In the process of relatively rotating the tube body 10 and the connecting ring 11 to fix the tube body 10 and the connecting ring 11, since the fourth inclined surface 27 has a small inclination, the fourth inclined surfaces 27 on the end surfaces of the two tube bodies 10 will contact each other and produce relative movement, thereby facilitating the tightening process; and after tightening, firstly, the first inclined surface 23 of the first arc-shaped strip 21 and the second inclined surface 24 of the second arc-shaped strip 22 are mutually engaged to perform preliminary locking, and secondly, since the third inclined surface 26 has a large inclination and is in the same direction as the tube body 10 is screwed into the connecting ring 11, it can play a more stable locking role, further improving the connection stability between the tube body 10 and the connecting ring 11, and between the two tube bodies 10, and avoiding connection failure.

[0030] Preferably, a sealing ring 13 is fixed to the end of the tube body 10 away from the first arc strip 21 , and the sealing ring 13 can be inserted between the tube body 10 and the connecting ring 11 to seal the tube body 10 .

[0031] Preferably, the surfaces where the first arc strip 21 and the second arc strip 22 are engaged with each other may be provided with anti-slip grooves.

[0032] The present invention improves the connection stability between the tube body 10 and the connecting ring 11 through the above arrangement.

[0033] The working principle of the utility model is as follows:

[0034] When the two tube bodies 10 are connected and fixed by the connecting ring 11, the end of the tube body 10 is first placed in the end of the connecting ring 11, and the tube body 10 and the connecting ring 11 are relatively rotated so that the first inclined surface 23 of the first arc-shaped strip 21 and the second inclined surface 24 of the second arc-shaped strip 22 are in contact with each other and move relative to each other, and then they are engaged with each other. After preliminary locking, the two tube bodies 10 are connected and fixed; in this process, the multiple tooth grooves 25 on the end surfaces of the two tube bodies 10 are engaged with each other to play a locking role, so as to further improve the connection stability between the tube body 10 and the connecting ring 11, and between the two tube bodies 10, and avoid connection failure; in addition, when disassembling, it is only necessary to rotate the tube body 10 and the connecting ring 11 in the opposite direction so that the multiple tooth grooves 25 on the end surfaces of the two tube bodies 10 are separated from each other, and the first arc strip 21 and the second arc strip 22 are separated from each other, and the tube body 10 and the connecting ring 11 can be disassembled. The utility model has a simple structure and is easy to operate during the installation and disassembly process.

[0035] Of course, a technical solution in which the inclination of the third bevel 26 is greater than that of the fourth bevel 27 may also be adopted. In this case, since the inclination of the fourth bevel 27 is smaller, the fourth bevels 27 on the end faces of the two tube bodies 10 contact and produce relative movement, which facilitates tightening the tube body 10 and the connecting ring 11. Since the inclination of the third bevel 26 is larger and is in the same direction as the tube body 10 is screwed into the connecting ring 11, it can play a more stable locking role, thereby improving the connection stability between the tube body 10 and the connecting ring 11 and between the two tube bodies 10, and avoiding connection failure.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
