[0011] Preferably, the distance between the two heat dissipation pipes is greater than the width of the semi-arc clamping plate.

[0012] Preferably, the front and rear ends of the metal tube are fixedly mounted with connecting rings, and the connecting rings are provided with a plurality of connecting holes.

[0013] The beneficial effects of the utility model are as follows: when using the device, the wear-resistant tube is first slidably sleeved on the inner rings of the two heat dissipation tubes in the metal tube, and then the guide ring is aligned with the limit groove in the other metal tube, and after inserting it, the two semi-arc connecting plates are rotated to make the two connecting blocks abut together, and at the same time, the two semi-arc clamping plates abut against the outer periphery of the heat dissipation tube, and the two connecting blocks can be fixed together by tightening the two bolts, thereby fixing the two semi-arc connecting plates together, and then making the two semi-arc clamping plates firmly clamp and fix the wear-resistant tube, and finally through the connecting rings and connecting rings on the two metal tubes The two metal tubes can be fixed by the connecting holes. When the wear-resistant tube needs to be replaced due to high wear, it is only necessary to loosen the bolts to make the wear-resistant tube lose the clamping and fixation of the two semi-arc clamping plates, and then remove the two metal tubes. Finally, the worn wear-resistant tube can be pulled out for replacement, so that the device can quickly and conveniently install and replace the wear-resistant tube; when the temperature of the wear-resistant tube is high, the temperature on the wear-resistant tube is absorbed by the heat dissipation tube, thereby reducing the temperature of the wear-resistant tube, and then the heat is discharged to the outside through multiple heat dissipation holes, which can effectively reduce the temperature of the wear-resistant tube and increase the service life of the wear-resistant tube.

[0023] like Figure 1-4As shown, a composite wear-resistant pipe fitting proposed by the utility model comprises a metal pipe 1, two heat dissipation pipes 2 are fixedly installed inside the metal pipe 1, the inner ring of the heat dissipation pipe 2 is movably sleeved with a wear-resistant pipe 3, the front end of the wear-resistant pipe 3 is fixedly connected with a guide ring 31, the end of the wear-resistant pipe 3 is provided with a limiting groove 32, and the limiting groove 32 matches the guide ring 31, a card slot 11 is provided in the middle part of the outer periphery of the metal pipe 1, two rotating holes 12 are provided on both sides of the card slot 11, and a rotating shaft 4 is rotatably connected between the two corresponding rotating holes 12, a semi-arc connecting plate 41 is fixedly sleeved on the outer periphery of the rotating shaft 4, a semi-arc clamping plate 42 is fixedly installed on the inner side of the semi-arc connecting plate 41, and the semi-arc clamping plate 42 is abutted against the outer periphery of the heat dissipation pipe 2, and a connecting component is fixedly installed on the outer periphery top of the semi-arc connecting plate 41 for fixing and connecting the two semi-arc connecting plates 41 together.

[0024] In this embodiment: the connection assembly includes a connection block 43 fixedly installed on the top of the semi-arc connection plate 41, the two connection blocks 43 are abutted on one side facing each other, and two threaded holes are provided on the connection blocks 43. Through this arrangement, the two connection blocks 43 are combined and abutted together; the threaded holes on the two connection blocks 43 are threadedly connected with bolts 44. Through this arrangement, tightening the two bolts 44 can fix the two connection blocks 43 together, thereby fixing the two semi-arc connection plates 41 together, and then the two semi-arc clamping plates 42 firmly clamp and fix the wear-resistant pipe 3; both sides of the semi-arc connection plate 41 are abutted against the two sides of the slot 11. Through this arrangement, a gap between the semi-arc connection plate 41 and the metal pipe 1 is avoided. Embodiment 2

[0025] like Figure 1-4 As shown, a composite wear-resistant pipe fitting proposed by the utility model, compared with the first embodiment, this embodiment also includes that a plurality of heat dissipation holes 13 are evenly and evenly spaced on the periphery of the metal tube 1. Through this arrangement, the heat on the heat dissipation tube 2 can be quickly released to increase the heat dissipation effect; the distance between the two heat dissipation tubes 2 is greater than the width of the semi-arc clamping plate 42. Through this arrangement, the two heat dissipation tubes 2 are prevented from limiting the clamping of the semi-arc clamping plate 42 on the wear-resistant tube 3, so that the semi-arc clamping plate 42 can smoothly abut against the periphery of the wear-resistant tube 3; the front and rear ends of the metal tube 1 are fixedly installed with connecting rings 14, and the connecting rings 14 are provided with a plurality of connecting holes 15. Through this arrangement, the two metal tubes 1 can be conveniently installed together.

[0026] Working principle: When using the device, first slide the wear-resistant tube 3 onto the inner rings of the two heat dissipation tubes 2 in the metal tube 1, then align the guide ring 31 with the limit groove 32 in the other metal tube 1, insert it and rotate the two semi-arc connecting plates 41, so that the two connecting blocks 43 abut together, and at the same time, the two semi-arc clamping plates 42 abut against the outer periphery of the heat dissipation tube 2, tighten the two bolts 44 to fix the two connecting blocks 43 together, thereby fixing the two semi-arc connecting plates 41 together, and then making the two semi-arc clamping plates 42 firmly clamp and fix the wear-resistant tube 3, and finally through the connecting rings 14 and the connecting rings on the two metal tubes 1 The connecting hole 15 can fix the two metal tubes 1. When the wear-resistant tube 3 is highly worn and needs to be replaced, it is only necessary to loosen the bolts 44 to make the wear-resistant tube 3 lose the clamping and fixing of the two semi-arc clamping plates 42, and then remove the two metal tubes 1. Finally, the worn wear-resistant tube 3 can be pulled out and replaced, so that the device can quickly and conveniently install and replace the wear-resistant tube 3; when the temperature of the wear-resistant tube 3 is high, the heat dissipation tube 2 absorbs the temperature on the wear-resistant tube 3, thereby reducing the temperature of the wear-resistant tube 3, and then discharges the heat to the outside through multiple heat dissipation holes 13, which can effectively reduce the temperature of the wear-resistant tube 3 and increase the service life of the wear-resistant tube 3.

[0027] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
