Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, specifically a nozzle-protected welding torch. Background Technology

[0002] During welding operations, the welding torch nozzle generates high temperatures, sparks, and intense arc light. These can not only cause burns and other injuries to operators, but also impair their vision during welding. Furthermore, the flying sparks can damage surrounding equipment or cause fires and other safety hazards.

[0003] Most existing welding torches lack effective protective devices. Some simple protective structures suffer from poor protective effects, inconvenient installation and disassembly, and inability to be adjusted according to actual welding needs. For example, some protective plates are fixed to the welding torch and cannot be adjusted in position according to the welding angle and range, resulting in inadequate protection in certain welding scenarios. Other protective structures use a single layer of material, which is insufficient to effectively block high temperatures and spatter, resulting in poor protective performance.

[0004] Therefore, this utility model provides a nozzle-protected welding torch to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a nozzle-protected welding torch, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nozzle-protected welding torch, comprising a handle, a welding torch tube fixedly mounted on the top of the handle, a welding torch nozzle fixedly mounted on the top of the welding torch tube, an installation assembly provided on the outer side of the welding torch tube, a protective plate provided on the outer side of the installation assembly, the installation assembly comprising a movable ring and a fixed ring, the fixed ring being fixedly mounted on the outer side of the welding torch tube, the movable ring being slidably connected to the outer side of the welding torch tube, the fixed ring having four insertion holes inside, and four insertion rods fixedly mounted on the side of the movable ring, the protective plate being composed of two semicircles, each semicircular mating groove being provided at the circular part of the two semicircles, the two protective plates being fastened to the outer side of the welding torch tube through the mating grooves.

[0007] Preferably, the protective plate is located between the movable ring and the fixed ring, and two fixing holes are opened inside the two protective plates. The insertion rod passes through the corresponding fixing hole and insertion hole, and the diameter of the insertion rod is the same as the diameter of the fixing hole and the insertion hole.

[0008] Preferably, a fixing block is fixedly installed on the outer side of the welding gun tube, a screw is rotatably connected to the outer side of the movable ring, the screw is screwed through the interior of the fixing block, and a knob is fixedly installed on the outer end of the screw.

[0009] Preferably, the screw thread lead angle is less than the equivalent friction angle, and the outer side of the screw is coated with a protective and lubricating grease, which is a grease with strong adhesion, anti-leakage, wear resistance and anti-pollution properties.

[0010] Preferably, the protective plate adopts a three-layer transparent tempered glass structure, with the first protective layer, the second protective layer and the third protective layer in sequence from the side closest to the welding gun nozzle to the outside. A buffer gap of 2-3mm is reserved between the three protective layers, and the edges are sealed and connected with high-temperature resistant sealant.

[0011] Preferably, the inner surface of the first protective layer is coated with a 0.1-0.2 mm thick nano-thermal insulation coating, which is made of a composite material of zirconium oxide and titanium dioxide; the second protective layer is embedded with a mesh-like metal wire reinforcement mesh, the diameter of which is 0.15-0.2 mm; the outer surface of the third protective layer is covered with a splash-proof and wear-resistant film, which is made of polyimide and has a thickness of 0.05-0.1 mm.

[0012] Beneficial effects

[0013] This invention provides a nozzle-protected welding torch. Compared with the prior art, it has the following advantages:

[0014] 1. This nozzle-protected welding torch features an installation assembly consisting of a movable ring, a fixed ring, a rod, and a socket, allowing for easy installation and removal of the protective plate.

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 This application provides a nozzle-protected welding torch, including a handle 1, a welding torch tube 4 fixedly installed on the top of the handle 1, a welding torch nozzle 5 fixedly installed on the top of the welding torch tube 4, an installation component 3 provided on the outside of the welding torch tube 4, and a protective plate 2 provided on the outside of the installation component 3.

[0025] The mounting assembly 3 includes a movable ring 31 and a fixed ring 32. The fixed ring 32 is fixedly installed on the outside of the welding torch tube 4, and the movable ring 31 is slidably connected to the outside of the welding torch tube 4. The fixed ring 32 has four insertion holes 38 inside, and four insertion rods 35 are fixedly installed on the side of the movable ring 31. The protective plate 2 is composed of two semicircles, and semicircular mating grooves 36 are opened at the circular part of each semicircle. The two protective plates 2 are fastened to the outside of the welding torch tube 4 through the mating grooves 36.

[0026] The protective plate 2 is located between the movable ring 31 and the fixed ring 32. Two fixed holes 37 are opened inside the two protective plates 2. The insertion rod 35 passes through the corresponding fixed hole 37 and insertion hole 38. The diameter of the insertion rod 35 is the same as the diameter of the fixed hole 37 and the insertion hole 38.

[0027] A fixing block 33 is fixedly installed on the outer side of the welding gun barrel 4. A screw 34 is rotatably connected to the outer side of the movable ring 31. The screw 34 is screwed through the interior of the fixing block 33. A knob 39 is fixedly installed on the outer end of the screw 34.

[0028] The screw 34 has a thread lead angle that is less than the equivalent friction angle. The outer side of the screw 34 is coated with a protective and lubricating grease. The grease is a type of grease with strong adhesion, anti-leakage, wear resistance and anti-pollution properties.

[0029] The protective plate 2 adopts a three-layer transparent tempered glass structure. From the side closest to the welding torch nozzle 5 to the outside, there are three layers: the first protective layer 21, the second protective layer 22, and the third protective layer 23. A buffer gap of 2-3mm is reserved between the three protective layers, and the edges are sealed and connected with high-temperature resistant sealant.

[0030] The inner surface of the first protective layer 21 is coated with a 0.1-0.2 mm thick nano heat-insulating coating, which is made of a composite material of zirconium oxide and titanium dioxide; the second protective layer 22 is embedded with a mesh of metal wire reinforcement, which has a diameter of 0.15-0.2 mm; the outer surface of the third protective layer 23 is covered with a splash-proof and wear-resistant film, which is made of polyimide and has a thickness of 0.05-0.1 mm.

[0031] The working principle and usage process of this embodiment are as follows:

[0032] When installing the protective plate 2, first fasten the two semi-circular protective plates 2 onto the outside of the welding torch tube 4 through the mating groove 36, so that the protective plate 2 is positioned between the movable ring 31 and the fixed ring 32, and ensure that the fixing hole 37 on the protective plate 2 corresponds to the insertion rod 35 on the movable ring 31 and the insertion hole 38 on the fixed ring 32. Then, turn the knob 39 to drive the screw 34 to rotate. Since the screw 34 is screwed to the fixing block 33, the rotation of the screw 34 will cause the movable ring 31 to slide towards the fixed ring 32. The insertion rod 35 gradually passes through the fixing hole 37 on the protective plate 2 and is inserted into the insertion hole 38 of the fixed ring 32 until the movable ring 31 and the fixed ring 32 clamp the protective plate 2 tightly, completing the installation of the protective plate 2.

[0033] The three layers of the protective plate 2 serve different functions. The nano-heat-insulating coating of the first protective layer 21 effectively blocks the high temperatures generated during welding; the metal wire reinforcing mesh of the second protective layer 22 enhances the strength of the protective plate 2; and the anti-spark and wear-resistant film of the third protective layer 23 prevents sparks from damaging the protective plate 2. The buffer gaps between the three layers act as a buffer when subjected to impact, further improving the protective performance.

[0034] When the protective plate 2 needs to be replaced or cleaned, turn the knob 39 in the opposite direction to move the movable ring 31 away from the fixed ring 32. The insertion rod 35 will then be pulled out from the fixed hole 37 and the insertion hole 38, and the protective plate 2 can be removed for the corresponding operation.
