[0039] The utility model provides a tobacco pipe structure 100 .

[0040] Reference Figures 1 to 5 , Figure 1 This is a schematic diagram of the forging structure of an embodiment of the tobacco pipe structure 100 of the present utility model; Figure 2 It is a schematic diagram of the structure of the initial stamping and forging of an embodiment of the tobacco pipe structure 100 of the utility model; Figure 3 It is another schematic diagram of the preliminary stamping and forging structure of an embodiment of the pipe structure 100 of the utility model; Figure 4 It is a structural schematic diagram of a glasses smoking pipe 10 according to an embodiment of the smoking pipe structure 100 of the utility model; Figure 5 It is a structural schematic diagram of another glasses smoking pipe 10 according to an embodiment of the smoking pipe structure 100 of the present invention.

[0041] In the embodiment of the utility model, the pipe structure 100 includes two glasses pipes 10, such as Figure 1 As shown, two glasses pipes 10 are forged into an integral structure. Each glasses pipe 10 includes a pipe stem 20 and a pipe head 30. One ends of the two pipe stems 20 are connected, and the two pipe heads 30 are respectively arranged at the other ends of the two pipe stems 20 that are far away from each other.

[0042] The pipe structure 100 of the technical solution of the utility model includes two glasses pipes 10, each of which includes a pipe stem 20 and a pipe head 30. One ends of the two pipe stems 20 are connected, and the two pipe heads 30 are respectively arranged at the other ends of the two pipe stems 20 that are far away from each other. There is no need to set welding points, which saves welding steps. Moreover, two glasses pipes 10 can be manufactured at one time, which reduces half of the manufacturing processes and improves the production capacity of the glasses pipes 10.

[0043] It can be understood that forging is a combination of forging and stamping. It is a forming method that uses the hammer, anvil, punch or die of a forging machine to apply pressure to the blank to cause it to undergo plastic deformation, thereby obtaining a product of the desired shape and size. In the present utility model, the blank is the raw material for forming the eye pipe, which is formed into Figure 1 The structure shown is a one-out-two arrangement, that is, the pipe structure 100 that can be formed by one forging can eventually be made into two glasses pipes 10, and the two glasses pipes 10 have the same structure 100 and can be used for the left and right pipe settings on the same frame, reducing the manufacturing steps and manufacturing processes of the glasses pipe 10, and the forging process is simple and convenient, saving labor costs. At the same time, the glasses pipe 10 formed by one forging reduces the number of welding points at the connection between the pipe rod 20 and the pipe head 30, reduces the welding steps, improves the manufacturing efficiency, and also improves the subsequent assembly efficiency.

[0044] Optionally, the connection between the pipe head 30 and the pipe stem 20 has a smooth transition; and / or, the pipe head 30 and the pipe stem 20 are both made of metal; and / or, the pipe head 30 and the pipe stem 20 are formed into an integral structure by forging.

[0045] In the present embodiment, two spectacle pipes 10 are integrally manufactured through a forging process, and the spectacle pipe 10 formed by one-time forging reduces the welding points at the connection between the pipe stem 20 and the pipe head 30, so that the connection between the pipe head 30 and the pipe stem 20 has a smooth transition, and the smooth transition can effectively improve the connection strength between the pipe head 30 and the pipe stem 20, and improve the structural strength of the spectacle pipe 10.

[0046] In another embodiment, two glasses pipes 10 are separated by a pipe structure 100 formed by forging at one time. The pipe structure 100 is set to be made of metal material, and the connection between the pipe head 30 and the pipe stem 20 is smoothly transitioned, so that the end of the pipe stem 20 away from the pipe head 30 can be directly welded, eliminating the need to drill holes on the frame for screw fixation when installing the glasses pipe 10, ensuring the structural strength of the frame. The metal glasses pipe 10 is not easy to be damaged after multiple bending and adjustment, and has high structural strength and long service life.

[0047] It is understandable that the metal material can be one of stainless steel, titanium metal, and titanium alloy.

[0048] In one embodiment, the pipe structure 100 formed by one-time forging includes two eyeglass pipes 10, and the pipe head 30 and the pipe stem 20 located in the same eyeglass pipe 10 are formed into an integral structure by forging. The integrally formed eyeglass pipe 10 has high structural strength and a smooth transition at the connection.

[0049] Optionally, a dividing portion 40 is provided at the connection position of the two pipe stems 20 , and the dividing portion 40 is used to separate the two glasses pipes 10 .

The dividing portion 40 is a dividing line or a dividing groove formed during the forging process, which is used to quickly confirm the dividing position, facilitate fast and balanced separation of the two spectacle pipes 10, and improve separation efficiency.

[0051] Optionally, each pipe rod 20 includes a connecting section 21 and a supporting section 22, and one end of the connecting sections 21 of the two pipe rods 20 is connected. The supporting section 22 is arranged at an angle with the connecting section 21, and the pipe head 30 is arranged at one end of the supporting section 22 away from the connecting section 21.

[0052] In this embodiment, each pipe stem 20 includes a connecting section 21 and a supporting section 22. The connecting parts of the two pipe stems 20 are connected and provided with a dividing portion 40. The connecting parts of the two pipe stems 20 are separated by the dividing portion 40 to completely separate the two eyeglass pipes 10. The separation method can be rolling or cutting.

[0057] It can be understood that the connecting section 21 and the supporting section 22 are both made of metal. In the subsequent assembly with the glasses, the angle can be adjusted according to actual needs to adjust the angle or structural shape of the connecting section 21 and the supporting section 22. For example, the connecting section 21 or the supporting section 22 can be partially or completely twisted to form a glasses pipe 10 with multiple segments to adapt to actual needs.

[0058] Combined with reference Figure 2 and Figure 4 As shown, optionally, the pipe head 30 is provided with a cup 30A with an opening 30B at one end, and the cup 30A is used to accommodate a nose pad of glasses.
