Description

Technical Field

[0001] This utility model relates to the field of building decoration materials and equipment technology, and in particular to a floor welding wire and welding nozzle. Background Technology

[0002] After prolonged use, resilient flooring may experience weld detachment due to shrinkage, affecting its appearance. The detached weld seam becomes wider, and its shape approximates an inverted trapezoid. Using conventional circular welding wire is insufficient to properly repair the detached flooring.

[0003] Existing solutions for repairing detached welds on floors use welding wire with a larger diameter. However, this method results in material waste and weak welds due to the significant difference in shape between the circular welding wire and the wide weld seam. Further solutions involve using two or more welding wires to repeatedly weld into the same detached weld seam, but this process is cumbersome and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a floor welding wire and welding nozzle that fits the irregular shape of the floor welding wire to the weld seam, increases the contact surface, and makes the weld strong.

[0005] The technical solution adopted by this utility model is:

[0006] A type of floor welding wire, characterized in that it is a long strip of semi-rigid PVC material with a cross-section that is approximately an inverted isosceles trapezoid. The upper base and two sides of the isosceles trapezoid are minor arc segments, and the lower base is a straight line. The chord length of the upper base is 6-7 mm, the chord length of the two sides is 3-4 mm, and the length of the lower base is 2-3 mm.

[0007] Furthermore, the chord length of the upper base is 6.5mm, the chord length of the two waists is 3.5mm, and the length of the lower base is 2mm.

[0008] Furthermore, the radius of the arc of the upper base is 5-6 mm, and the radius of the arc of the two waists is 3-4 mm.

[0009] A welding torch nozzle is characterized by comprising a sleeve and a conduit, wherein the conduit is connected to the sleeve at an acute angle, a wide opening is formed at the front end of the connection, and an upward flange is formed at the front end of the conduit. The sleeve is used to connect to the heating head of the welding torch, the inner hole shape of the conduit is matched with the ground wire, and the conduit is used to insert the ground wire with a clearance fit.

[0010] Furthermore, the cross-section of the flange is arc-shaped, and a reinforcing rib is provided between the flange and the conduit.

[0011] Furthermore, reinforcing plates are welded to both sides of the connection between the conduit and the sleeve.

[0012] Furthermore, the acute angle is 20°-40°.

[0013] Furthermore, a notch is formed at the rear end of the sleeve.

[0014] The beneficial effects of this utility model are:

[0015] (1) After welding the irregular weld lines of this patent, the flattened part is small, so there is less material waste;

[0016] (2) The irregular weld wire is shaped to fit the weld seam, the contact surface is large, and the weld is firm;

[0017] (3) Welding is completed in one go. Attached Figure Description

[0033] The following detailed description, in conjunction with the accompanying drawings, illustrates the specific implementation of a floor welding wire and welding torch of this utility model.

[0034] The floor welding line 1 of this patent is a long strip of semi-rigid PVC material with a cross-section that is approximately an inverted isosceles trapezoid. The upper base 2 and the two legs 3 of the isosceles trapezoid are both minor arc segments, while the lower base 4 is a straight line. The chord length of the upper base 2 is 6.5 mm, the chord length of the two legs 3 is 3.5 mm, and the length of the lower base 4 is 2 mm. The arc radius of the upper base 2 is 5.5 mm, and the arc radius of the two legs 3 is 3.8 mm. This dimension can be adjusted as needed to suit different thicknesses and different spacing between the two floor panels 13.

[0035] See appendix Figure 3 , 4 The welding nozzle 5 of this patent is designed for the aforementioned welding wire 1, and includes a sleeve 6 and a conduit 7. The conduit 7 and the sleeve 6 are connected at an acute angle of 20°-40°, forming a wide opening 8 at the front end of the connection. An upward-facing flange 9 is formed at the front end of the conduit 7, and the cross-section of the flange 9 is arc-shaped. A reinforcing rib 10 is provided between the flange 9 and the conduit 7. Reinforcing plates 11 are welded to both sides of the connection between the conduit 7 and the sleeve 6. A notch 12 is formed at the rear end of the sleeve 6 for connection with the heating head of the welding gun. The inner hole shape of the conduit 7 matches the ground welding wire 1, and the conduit 7 is used for gap-fit ​​insertion of the ground welding wire 1.

[0036] See appendix Figure 5 When two adjacent floorboards 13 shrink, the arcs on the sides of the original floorboards 13 break, forming a gap 14 with two upper arcs and a square cross-section below. At this time, the circular welding wire cannot match the shape, resulting in many problems such as weak welding.

[0037] See appendix Figure 6 , 7 When welding the welding line 1 of this patent, the shape of the welding line 1 is similar to the cross-section of the connection point of the floor 13, so that the weld is firm and can fill the small gaps 14. After welding, the excess part is scraped off, and the repair is completed.

[0038] During welding, the welding wire 1 is inserted into the conduit 7 of the welding torch nozzle 5, and the sleeve 6 is inserted into the heating tube of the welding torch. The welding torch is turned on. Due to the heat conduction of the connection part, the heat on the sleeve 6 is transferred to the front end of the conduit 7. The heated part of the welding wire 1 at the front end of the conduit 7 melts and the welding wire 1 is sent to the gap 14 between the floor 13. Through the flange 9 at the front end of the conduit 7, the molten welding wire 1 is sent out while the welding wire 1 is pressed down into the gap 14 to complete the welding.

[0039] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
