[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 - Figure 3The utility model provides an embodiment: an auxiliary positioning structure for welding building pipes, comprising two frames 1, one end of the adjacent side of the two frames 1 is rotatably connected, the other end of the adjacent side of the two frames 1 is connected through a chimeric component, a plurality of tripods 2 are fixedly connected to the bottom side of the frame 1, a screw rod 3 is rotatably connected to the middle end of the plurality of tripods 2, a transmission member 4 is connected between the frame 1 and the screw rod 3, one end of the transmission member 4 is threadedly connected to the outer wall of the screw rod 3, the other end of the transmission member 4 is slidably connected to the inner wall of the frame 1, a collar 8 is connected to the top side of the transmission member 4, the top sides of the two frames 1 away from each other are fixedly connected to collar 2 9, and the top ends of the collar 1 8 and the collar 2 9 are threadedly connected to tightening bolts 10;

[0027] Specifically, the pipe welding auxiliary positioning structure is made of aluminum alloy as a whole, with light weight, small volume, and no driving structure, so as to achieve lightweight design, facilitate transportation and handling, and greatly improve the convenience of the structure. The thread directions of the surfaces of the two screw rods 3 are opposite, so that when the two screw rods 3 rotate in the same direction, the transmission member 4 driven by them moves toward or away from each other, so that the top side collar 8 drives the fixed pipe to move, and adjusts the distance between the two pipes for welding. The inside of the frame 1 can limit the transmission member 4 to prevent the transmission member 4 from rotating due to the transmission of the screw rod 3. The separated ends of the two screw rods 3 are both provided with force-applying components, and the screw rods 3 can be easily rotated by the force-applying components. The collar 18 and the collar 29 are both used to sleeve the pipes for welding, and the tightening bolts 10 can be used to twist the collar 18 and the collar 29 to displace them until they are against the surface of the pipe, so as to limit and fix the pipe.

[0028] Reference Figure 3 and Figure 5 , the ferrule 11 and buckle 12 are located on the side close to the two screw rods 3, one end of the ferrule 11 is fixedly connected to one of the screw rods 3, one end of the buckle 12 is fixedly connected to the other screw rod 3, a slot is provided on the inner wall of the other end of the ferrule 11, and protrusions are provided on the top and bottom sides of the other end of the buckle 12. The ferrule 11 is sleeved on the outer wall of the buckle 12, and the protrusion is engaged with the slot;

[0029] Specifically, the clamping sleeve 11 has a certain elasticity. When the buckle 12 is inserted into the clamping sleeve 11, the two ends of the clamping sleeve 11 will be squeezed by the protrusions on the buckle 12, and deform and deviate, so that the buckle 12 is inserted into the clamping sleeve 11 until the protrusions press into the slot, so that the clamping sleeve 11 clamps and restricts the buckle 12, so that the two screw rods 3 are connected and fixed to each other, so that one of the screw rods 3 drives the other screw rod 3 to rotate synchronously when rotating. When the two frames 1 are folded and merged, the clamping sleeve 11 will deviate on the buckle 12, and deform and expand under the contact of the protrusions, so that the buckle 12 will fall out of the clamping sleeve 11.

[0030] Reference Figure 1 and Figure 4 , a frame 5 is fixedly connected to the top side of the transmission member 4, one end of the frame 5 is rotatably connected to the screw 2 6, the other end of the frame 5 is fixedly connected to the frame 5, one end of the bottom side of the collar 1 8 is threadedly connected to the outer wall of the screw 2 6, and the other end of the bottom side of the collar 1 8 is slidably connected to the outer wall of the slide rod 7;

[0031] Specifically, the slide bar 7 can limit the collar 1 8 to prevent the collar 1 8 from rotating due to the transmission of the screw 2 6. The collar 1 8 can be connected to the fixed pipe for longitudinal displacement by turning the screw 2 6, and the position can be adjusted for the second time, so that the coaxiality between the two pipes is improved, and the welding accuracy and quality are further improved. After completing the secondary adjustment, the tightening bolt 10 on the collar 2 9 can be tightened to fix the other end of the pipe, so as to completely fix the pipe for welding.

[0032] Reference Figure 2 , Figure 5 and Figure 6 , two engaging grooves 13 are respectively provided at the other end of the adjacent side of the two frames 1, and the two engaging grooves 13 are slidably connected with engaging members 14 inside. The separated sides of the two frames 1 are fixedly connected with handles 15, and the separated sides of the two handles 15 are provided with engaging grooves 2 16, and the engaging members 14 are also slidably connected inside the two engaging grooves 2 16;

[0033] Specifically, when the positioning structure needs to work, after unfolding, the engaging member 14 can be inserted into the engaging groove 1 13 on the frame 1, thereby connecting the two frames 1 and preventing the frames 1 from rotating. When the positioning structure needs to be stored, the engaging member 14 is taken out of the engaging groove 1 13, and one of the frames 1 together with the structure connected thereto is rotated 180° around the other frame 1, so that the handles 15 on the two frames 1 are combined, and the engaging grooves 2 16 on the handles 15 are combined. At this time, the engaging member 14 is inserted into the two engaging grooves 2 16 to limit the two handles 15 connected to the frames 1 and prevent them from separating, so as to prevent the positioning structure from being folded and stored from separating.

[0034] Working principle: When positioning the pipe for welding, insert the two pipes into the sleeve 1 8 and the sleeve 2 9 at both ends respectively, and tighten the locking bolts on the sleeve 1 8 to displace it until it rests on the surface of the pipe, so that the pipe is fixed on the sleeve 1 8. Then turn the screw 1 3 to make the sleeve 1 8 on the top side drive the fixed pipe to displace, adjust the distance between the two pipes, and then turn the screw 2 6 to make the sleeve 1 8 connect the fixed pipe to displace longitudinally, and adjust the position for the second time, so as to improve the coaxiality between the two pipes, thereby further improving the accuracy and quality of welding. After completing the secondary adjustment, tighten the locking bolts 10 on the sleeve 2 9 to fix the other end of the pipe, so as to completely fix the pipe for welding. When there is no need to perform welding work and the structure needs to be transported, the engaging piece 14 is taken out from the engaging groove 13, and one of the frames 1 together with the structure connected thereto is rotated 180° around the other frame 1, so that the handles 15 on the two frames 1 are merged, and the engaging grooves 2 16 on the handles 15 are merged. At this time, the engaging piece 14 is inserted into the two engaging grooves 2 16 to limit the two handles 15 connected to the frames 1 to prevent separation.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
