[0034] Example

[0035] like Figure 1-2 As shown, an embodiment of the utility model is a metal locking heat-crimped pipe joint, comprising a plurality of connection units 100, wherein the connection units 100 include an arc-shaped plate 110 and two ear plates 120; the two ear plates 120 are respectively arranged at both ends of the arc-shaped plate 110, for realizing the connection of the plurality of connection units 100; and when the plurality of connection units 100 are connected, the plurality of arc-shaped plates 110 of the plurality of connection units 100 cooperate with each other, for crimping on a pipe 400 to realize the connection of the pipe 400; wherein the connection units 100 are made of heat-conducting material.

[0036] Among them, the connecting unit 100 is a heat-conducting material. When the pipe 400 joint is used to connect the pipe 400, after combining multiple connecting units 100 to form an overall joint structure, the heat can be transferred to the pipe 400 by heating the connecting unit 100, thereby softening the pipe body and ensuring the connection effect between the pipe 400 and the joint.

[0037] Specifically, those skilled in the art should know that Figure 3 As shown, the metal locking heat-crimped pipe 400 joint cooperates with the pipe 400, which is equivalent to forming a flange joint at the end of the pipe 400, and the joint is adapted to the pipe 400 to form a whole, and by adding a conventional flange plate 510 structure, the connection between the two pipes 400 is achieved, and compared with the traditional method, no crimping machinery is required.

[0038] In the present solution, the pipe 400 joint includes a plurality of connection units 100, wherein the connection units 100 include an arc plate 110 and two ear plates 120 arranged at both ends of the arc plate 110, wherein the ear plates 120 are used to realize the connection of the plurality of connection units 100, and when the plurality of connection units 100 are connected, the 360° circular ring structure can realize the wrapping of the pipe 400, thereby forming a joint structure; and since the connection units 100 are heat-conducting materials, after the wrapping is completed, the connection units 100 can be heated, and the heat can be transferred to the pipe body through the connection units 100, thereby softening the polyethylene and inorganic non-metallic reinforcing materials in the polyethylene composite pipe 400, and forming the pipe 400 and the joint into a complete whole. Compared with the prior art method of using a crimping machine, while ensuring the connection effect, it does not require a high-power crimping machine and is not limited by the diameter of the pipe 400.

[0039] In some embodiments, the side of the arc plate 110 that is in contact with the pipe 400 is a fitting side 111 , and the fitting side 111 is provided with a threaded structure.

[0040] In some embodiments, the side of the arc plate 110 that is in contact with the pipe 400 is a fitting side 111 , and the fitting side 111 is provided with a groove structure.

[0042] Furthermore, the groove structure includes a plurality of grooves, and the plurality of grooves are arranged at intervals along a direction parallel to the axis of the arc plate 110 .

[0043] In some embodiments, the ear plate 120 is provided with a through hole 121 for connecting with another ear plate 120 , wherein the through hole 121 of the ear plate 120 of one connecting unit 100 is connected with the through hole 121 of the ear plate 120 of another connecting unit 100 via a bolt 200 .

[0044] Specifically, through the structural design of the through hole 121 and the bolt 200, the connection strength between the ear plates 120 is ensured while facilitating the connection.

[0045] In some embodiments, the bolt 200 is provided with a spring washer.

[0046] Specifically, as those skilled in the art should know, the provision of the spring gasket reduces the probability of the joint of the pipeline 400 becoming loose due to thermal expansion and contraction.

[0047] Among them, the spring gasket is conventional technology, and its specific structure is not described here.

[0048] In some embodiments, there are multiple through holes 121.

[0049] Specifically, the structural design of the plurality of through holes 121 can ensure the connection strength between the ear plates 120 .

[0050] like Figure 4 As shown, an embodiment of the utility model also provides an auxiliary connection mechanism for realizing the connection of the above-mentioned metal locking heat-crimping pipe joint 400, characterized in that it includes a heating chamber 310, and the heating chamber 310 is used to realize the heating of the above-mentioned metal locking heat-crimping pipe joint 400.

[0051] Among them, the heating chamber 310 is used to heat the pipe 400 structure. As those skilled in the art should know, the size of the heating chamber 310 should be compatible with the pipe 400 joint. When the pipe 400 joint is buckled on the pipe 400, the whole is placed in the heating chamber 310 for heating.

[0052] Specifically, there is no limitation on the specific heating method, and either electric heating or flame heating may be used.

[0053] In some embodiments, the heating chamber 310 has two coaxially arranged openings, and a first support member 320 and a second support member 330 are respectively provided on the side away from each other of the two openings, wherein the first support member 320 is used to cooperate with the outer wall of the pipe 400, and the second support member 330 is used to cooperate with the inner cavity of the pipe 400, so as to fix the pipe 400 in the heating chamber 310.

[0054] Specifically, through the structural design of the first support member 320 and the second support member 330 , it is possible to support the overall structure, thereby ensuring the stability of the pipeline 400 .

[0055] In some embodiments, the first support member 320 includes a first support rod 322 , and the second support member 330 includes a second support rod 332 , wherein both the first support rod 322 and the second support rod 332 are telescopic rod structures.

[0056] Specifically, the telescopic rod structure is adopted to achieve relative position adjustment, thereby ensuring heating uniformity.

[0057] Specifically, the first support rod 322 further includes a support drag 321 , and the support drag 321 is used to contact the outer side wall of the pipeline 400 to support the pipeline 400 .

[0058] Specifically, the second support block further includes a support head 331 , and the support head 331 is used to penetrate into the inner cavity of the pipe 400 to support the pipe 400 .

[0059] Furthermore, in order to ensure the supporting effect, the supporting head 331 can be moved relative to the axis of the pipe 400, so as to ensure the matching effect with the pipe 400. It should be noted that the movement can be achieved by setting the supporting head 331 as a telescopic head or setting a movable structure, which is a conventional technical means and will not be elaborated here.

[0060] Furthermore, in order to ensure the matching effect between the support head 331 and the inner cavity of the pipe 400, the matching ends of the support head 331 and the pipe 400 adopt a truncated cone structure.

[0061] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
