Description

Technical Field

[0001] This utility model relates to the field of welding torches, specifically a welding torch with a protective structure. Background Technology

[0002] The protective design of welding torches typically includes the use of insulating materials for the handle and connecting parts to prevent electric shock caused by current passing through the torch housing. The torch housing and handle are often made of high-temperature resistant materials and have a heat insulation layer. Secondly, during high-frequency welding, the welding torch may overheat due to prolonged exposure to high temperatures, leading to equipment damage. Welding torches usually include a coolant circulation system to reduce the torch temperature through water or air cooling.

[0003] There are some defects in the operation of existing protective structures for welding torches: when welding torches are used for welding operations, the welding process will inevitably generate a large amount of high temperature, sparks and spatter. However, the plastic material used for the welding torch handle is directly exposed to sparks and spatter, which can damage the plastic material of the handle, causing problems such as deformation and melting of the handle. Secondly, sparks and spatter can easily cause injury to operators, thus creating safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a welding torch with a protective structure to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A welding torch with a protective structure includes a welding torch handle. A metal tube is fixedly installed at the upper end of the inclined side of the welding torch handle, and an end fitting is fixedly installed at the lower end of the inclined side of the welding torch handle. A welding torch head is fixedly installed at one end of the metal tube. An isolation and protection component for protecting against sparks generated during welding is provided on the outer wall of the end of the metal tube near the welding torch head. Locking components for fixing and locking are provided on both sides of the isolation and protection component.

[0006] Preferably, the isolation and protection component includes a first transparent barrier plate and a second transparent barrier plate. The first and second transparent barrier plates are semi-circular and transparent. Sliding blocks are fixedly connected to opposite sides of the inner walls of the first and second transparent barrier plates. The inner walls of the first and second transparent barrier plates respectively contact the outer sides of the first and second clamping blocks. Sliding grooves are formed at one end of the inner walls of the outer walls of the first and second clamping blocks.

[0007] Preferably, magnetic blocks are fixedly installed on the upper and lower sides of one side of the first clamping block, and magnetic grooves are opened inside the upper and lower sides of one side of the second clamping block. The magnetic blocks are magnetically inserted into the inside of the magnetic grooves, and the inner walls of the first and second clamping blocks are clamped and contacted with the outside of the metal tube.

[0008] Preferably, the outer walls of the first clamping block and the second clamping block are respectively provided with T-shaped grooves and fixing holes. Sliding blocks are slidably connected inside the sliding grooves of the first clamping block and the second clamping block. T-shaped mounting slots are provided at one end of the opposing sides of the two sliding blocks.

[0009] Preferably, the locking assembly includes a fixing cylinder, which is fixedly sleeved inside the fixing hole groove. A through opening is provided through the inner wall of the fixing cylinder. A T-shaped insert is slidably sleeved inside the fixing cylinder and the through opening. The T-shaped insert is slidably sleeved inside the T-shaped groove.

[0010] Preferably, the T-shaped insert is rotatably connected to a threaded rod, which is rotatably sleeved inside the fixed cylinder and the T-shaped groove. A sealing cap is sleeved through the outer side of the threaded rod away from the T-shaped insert, one end of which is fixedly installed at one end of the fixed cylinder, and a rotating handle is fixedly installed at one end of the threaded rod.

[0011] Preferably, the T-shaped insert is inserted into the T-shaped slot of the sliding block by sliding movement.

[0012] The beneficial effects of this utility model are: 1. This utility model uses an arc-shaped barrier formed by the combination of the first and second transparent partition plates to surround the metal tube in all directions, forming a closed protective area. This effectively blocks the spread of sparks and high-temperature spatter generated during welding towards the handle, preventing burns to the operator's hands and arms. It also reduces damage caused by spatter adhering to the equipment. The first and second clamping blocks can be quickly clamped and fixed to the outside of the metal tube through the magnetic attraction of the magnetic block and the magnetic groove, forming a stable mounting base that is easy to disassemble and maintain at any time.

[0013] 2. This utility model achieves sliding block locking by fully embedding the T-shaped insert of the locking component, thereby further strengthening the locking and fixing of the transparent partition plate. At the same time, it facilitates the disassembly, installation and replacement of the transparent partition plate, reduces safety hazards caused by loose protective components, provides reliable safety protection for operators, and reduces the risk of burns from high-temperature splashes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figure 1 and Figure 2 As shown, a welding torch with a protective structure includes a welding torch handle 1, a metal tube 2 fixedly installed at the upper end of the inclined side of the welding torch handle 1, an end fitting 5 fixedly installed at the lower end of the inclined side of the welding torch handle 1, a welding torch head 3 fixedly installed at one end of the metal tube 2, an isolation and protection component 4 for protecting against sparks generated during welding is provided on the outer wall of the end of the metal tube 2 near the welding torch head 3, and locking components 6 for fixing and locking are provided on both sides of the isolation and protection component 4.

[0018] In a specific embodiment, the welding torch handle 1 provides a gripping fulcrum for the operator, facilitating the control of the overall posture of the welding torch. The metal tube 2 serves as a connection and conduction carrier, while the welding torch head 3, fixed at one end, is the core component directly acting on the welding area. The welding current, welding wire (or welding rod), etc., required for welding are transmitted to the welding torch head 3 through the internal channels of the metal tube 2, completing the basic welding process of arc generation and melting of welding materials. The end connector 5 is used to connect external equipment (such as power supply, wire feeder, cooling system, etc.). During welding, when the welding torch head 3 contacts the workpiece and generates an arc, it is accompanied by a large amount of sparks and high-temperature molten slag splashing. The isolation and protection component 4, located on the outer wall of the metal tube 2 near the welding torch head 3, forms a barrier through physical shielding, effectively blocking the splashing sparks and molten slag, preventing them from directly contacting the operator, other parts of the welding torch (such as the handle and pipeline), or surrounding flammable materials, thus reducing burns.

[0019] Please refer to Figures 1 to 5 As shown, as a technical optimization of this utility model, the isolation and protection component 4 includes a first transparent partition plate 41 and a second transparent partition plate 42. The first transparent partition plate 41 and the second transparent partition plate 42 have a semi-circular and transparent structure. Sliding blocks 48 are fixedly connected to opposite sides of the inner walls of the first transparent partition plate 41 and the second transparent partition plate 42. The inner walls of the first transparent partition plate 41 and the second transparent partition plate 42 respectively contact the outer sides of the first clamping block 43 and the second clamping block 44. Sliding grooves 47 are provided at one end of the inner walls of the outer walls of the first clamping block 43 and the second clamping block 44. Magnetic blocks 46 are fixedly installed on the upper and lower sides of one side of the first clamping block 43. Magnetic grooves 45 are provided on the upper and lower sides of one side of the second clamping block 44. The magnetic blocks 46 are magnetically inserted into the inner walls of the magnetic grooves 45. The inner walls of the first clamping block 43 and the second clamping block 44 are clamped and contacted with the outer side of the metal tube 2.

[0020] Furthermore, the outer walls of the first clamping block 43 and the second clamping block 44 are respectively provided with T-shaped grooves 49 and fixing holes 410. Sliding blocks 48 are slidably connected inside the sliding grooves 47 of the first clamping block 43 and the second clamping block 44. T-shaped mounting slots 411 are provided at one end of the opposing sides of the two sliding blocks 48.

[0021] In a specific embodiment, the first and second transparent partition plates 41 and 42 adopt a semi-circular transparent structure. When combined, they form an arc-shaped barrier around the metal tube 2, which can block the sparks and spatter generated during welding from spreading towards the handle. At the same time, the transparent material does not affect the operator's observation of the welding area. The first clamping block 43 and the second clamping block 44 can be quickly clamped and fixed to the outside of the metal tube 2 through the magnetic attraction of the magnetic block 46 and the magnetic groove 45, forming a stable mounting base. This magnetic connection method not only ensures the clamping force but also facilitates disassembly and maintenance at any time. Take the first and second transparent partition plates 41 and 42, align the sliding block 48 on their inner walls with the sliding groove 47 of the first and second clamping blocks 43 and 44, and insert them along the groove direction. The position of the transparent partition plate is locked by the cooperation of the T-shaped mounting slot 411 with the T-shaped groove 49 and the fixing hole slot 410.

[0022] Please refer to Figure 2 , Figures 4 to 5 As shown, as a technical optimization of this utility model, the locking component 6 includes a fixing cylinder 61, which is fixedly sleeved inside the fixing hole groove 410. A through-hole 62 is provided through the inner wall of the fixing cylinder 61. A T-shaped insert 63 is slidably sleeved inside the fixing cylinder 61 and the through-hole 62. The T-shaped insert 63 is slidably sleeved inside the T-shaped groove 49. A threaded rod 64 is rotatably connected inside the T-shaped insert 63. The threaded rod 64 is rotatably sleeved inside the fixing cylinder 61 and the T-shaped groove 49. A sealing cover 65 is provided through the outer side of the threaded rod 64 away from the T-shaped insert 63. One end of the sealing cover 65 is fixedly installed at one end of the fixing cylinder 61. A rotating handle 66 is fixedly installed at one end of the threaded rod 64. The T-shaped insert 63 is inserted into the T-shaped slot 411 of the sliding block 48 by sliding movement.

[0023] In a specific embodiment, by cooperating with the T-shaped slot 411, the T-shaped groove 49, and the fixing hole 410, the rotating handle 66 is turned to drive the threaded rod 64 to rotate clockwise. The threaded rod 64, through threaded transmission, pushes the T-shaped insert 63 to slide outward along the through-hole 62 of the fixing cylinder 61. The front end of the T-shaped insert 63 is inserted into the T-shaped slot 411 of the sliding block 48. The rotation continues until the T-shaped insert 63 is fully embedded, thereby locking the sliding block 48. This further strengthens the locking and fixing of the transparent partition plate, while facilitating the disassembly, installation, and replacement of the transparent partition plate.

[0024] In use, the first and second transparent partition plates 41 and 42 adopt a semi-circular transparent structure. When combined, they form an arc-shaped barrier around the metal tube 2, which can prevent sparks and spatter generated during welding from spreading towards the handle. At the same time, the transparent material does not affect the operator's observation of the welding area. The first clamping block 43 and the second clamping block 44 can be quickly clamped and fixed to the outside of the metal tube 2 through the magnetic attraction of the magnetic block 46 and the magnetic groove 45, forming a stable mounting base. By rotating the rotating handle 66, the threaded rod 64 is driven to rotate clockwise. The threaded rod 64 pushes the T-shaped insert 63 to slide outward along the through-hole 62 of the fixed cylinder 61 through the threaded transmission. The front end of the T-shaped insert 63 is inserted into the T-shaped slot 411 of the sliding block 48. The rotation continues until the T-shaped insert 63 is fully embedded, realizing the rigid locking of the sliding block 48 and the fixed structure, thereby further strengthening the locking and fixing of the position of the transparent partition plate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
