Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a disassembly and assembly structure for a welding gas protective cover. Background Technology

[0002] Shielding gas refers to the gas used during welding to protect the molten metal droplets, molten pool, and weld zone. It protects the high-temperature metal from external gases. Welding shielding gas can be a single gas. The purpose of using welding shielding gas is to improve weld quality, reduce the width of the weld heating zone, and prevent material oxidation. Therefore, workers need to install a protective cover on the outside of the welding torch connector.

[0003] Publication No. CN213003410U discloses a welding gas protective cover. This device, by setting a first limiting groove, a first limiting block, a second limiting groove, and a second limiting block, facilitates the user's installation of a first and second semi-circular arc-shaped protective cover onto a sealing rubber ring. The first and second semi-circular arc-shaped protective covers can then be fixed by rotating a threaded sleeve. A threaded ring can be used to fix the bottom of the first and second semi-circular arc-shaped protective covers, thus preventing incomplete sealing at the bottom during use. However, this patent still has the following problems in practical use:

[0004] The device allows users to install the first and second semi-circular protective covers onto the sealing rubber ring, and then fix the first and second semi-circular protective covers by rotating the threaded sleeve. When the welding torch connector is in a narrow position, the operator may need to spend more time and effort rotating the threaded sleeve and threaded ring to install and remove the protective covers. This not only reduces work efficiency but may also increase the difficulty and complexity of operation, especially in situations where the protective covers need to be frequently replaced or cleaned, causing inconvenience to the operator.

Currently, when the user installs the first and second semi-circular protective covers onto the sealing rubber ring, and then fixes the first and second semi-circular protective covers by rotating the threaded sleeve, the operator may need to spend more time and effort to rotate the threaded sleeve and threaded ring to install and disassemble the protective covers when the welding torch connector is in a narrow position. This not only reduces work efficiency, but may also increase the difficulty and complexity of operation, especially in situations where the protective covers need to be frequently replaced or cleaned, causing inconvenience to the operator.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disassembly and assembly structure for a welding gas protective cover, including a welding torch connector, wherein a conductive nozzle is provided at the bottom end of the welding torch connector, and a fixing sleeve is installed on the outer side of the welding torch connector; a fixing mechanism is provided on the outer side of the welding torch connector, and a connecting component is provided inside the fixing mechanism.

[0008] The fixing mechanism includes a first arc-shaped cover and a second arc-shaped cover, which are sleeved on the outside of the welding gun connector. A first connecting plate is installed on one side of the first arc-shaped cover, and a second connecting plate is installed on one side of the second arc-shaped cover. Fixing boxes are symmetrically installed inside both ends of the second connecting plate, and insert plates are symmetrically installed on both ends of the first connecting plate. The insert plates are inserted into the fixing boxes. A moving rod is slidably connected inside one side of the fixing box. A retractable rod is symmetrically installed on the inner side of the fixing box, and a first telescopic spring is sleeved on the outer side of the retractable rod. A push plate is installed at one end of the retractable rod, and insert blocks are symmetrically installed on one side of the push plate. The insert blocks are inserted into the insert plates. Movable rods are symmetrically rotatably connected to both sides of the moving rod, and one end of the movable rod is rotatably connected to the push plate.

[0009] Preferably, the connecting assembly includes limiting boxes symmetrically installed inside both sides of the fixing sleeve, and a fixing tube is installed on one side of the top of the limiting box. A sliding rod is slidably connected inside the fixing tube, and a second telescopic spring is sleeved on the outside of the sliding rod. A slider is installed at the bottom end of the sliding rod, and a push rod is installed at the bottom end of the slider. A sliding plate is slidably connected inside one side of the limiting box, and toothed blocks are installed on one side of each sliding plate. The toothed blocks are inserted into the first arc-shaped cover and the second arc-shaped cover. A connecting rod is rotatably connected between the push rod and the sliding plate.

[0010] Preferably, a groove is provided on one side of the inner side of the limiting box, and one side of the slide plate is slidably connected to the groove, and a pull ring is installed at the top of the slide rod.

[0011] Preferably, the second connecting plate has symmetrically provided mounting grooves at both ends, and support rods are symmetrically installed inside the mounting grooves. A movable plate is slidably connected between the outer sides of the support rods, and one end of the movable rod is fixedly connected to the movable plate.

[0012] Preferably, an annular rubber sleeve is installed on the outer side of the welding torch connector, and an arc groove is opened on the inner side of the top of the first arc-shaped cover and the second arc-shaped cover, and the annular rubber sleeve and the arc groove are fitted together.

[0013] Preferably, the top ends of the first and second arc-shaped covers are fitted with the inner side of the fixed sleeve with a clearance.

[0014] Preferably, the first arc-shaped cover and the second arc-shaped cover are fitted together, and the first connecting plate and the second connecting plate are fitted together.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A disassembly and assembly structure for a welding gas protective cover is described below: The operator inserts the first and second arc-shaped covers into the inner side of the bottom of the fixed sleeve. The operator then pulls the moving rod, which slides inside the fixed box. The movement of the moving rod causes the movable rod to rotate, which in turn causes the push plate to move. At this time, the retracting rod and the first telescopic spring retract, and the first telescopic spring quickly resets the position, allowing the insert block and the insert plate to connect. This achieves the effect of quickly splicing and fixing the first and second arc-shaped covers, thereby stabilizing the welding torch connector. The protective system allows for quick and easy installation and removal of the first and second arc-shaped covers, significantly reducing the difficulty and time required for operations in confined spaces. This also improves the cleaning efficiency of the first and second arc-shaped covers, preventing gas path blockage and ensuring welding quality. By having the operator pull a sliding rod, the slider moves inside the fixed tube, causing the second telescopic spring to retract. The spring's restoring property allows multiple sets of toothed blocks to engage with the first and second arc-shaped covers, achieving rapid fixation between their tops. This greatly improves the installation stability of the first and second arc-shaped covers, preventing instability in gas protection.

[0016] 1. The operator inserts the first and second arc-shaped covers into the inner side of the bottom of the fixed sleeve. At this time, the first and second arc-shaped covers are aligned, the first and second connecting plates are aligned, and the insert plate is inserted into the fixed box. The operator then pulls the moving rod to slide inside the fixed box. The movement of the moving rod causes the movable rod to rotate, which in turn moves the push plate. At this time, the retracting rod and the first telescopic spring retract. By releasing the moving rod, the first telescopic spring quickly returns to its original position, allowing the insert block to be inserted into the insert plate. This achieves the effect of quickly splicing and fixing the first and second arc-shaped covers, thus providing stable protection for the welding gun connector. The quick and convenient installation and disassembly of the first and second arc-shaped covers greatly reduces the difficulty and time of operation in confined spaces. Compared with the existing threaded connection method, this is more convenient, improves the cleaning efficiency of the first and second arc-shaped covers, avoids gas path blockage, weakens the gas protection effect, and affects welding quality, bringing convenience to the operator during use.

[0017] 2. When the operator pulls the sliding rod, the slider slides inside the fixed tube. At this time, the second telescopic spring contracts, and the slider moves the push rod upward. The movement of the push rod causes the connecting rod to rotate. The rotation of the connecting rod pulls the slide plate inside the limit box. By releasing the sliding rod, and through the restoring property of the second telescopic spring, multiple sets of toothed blocks can be inserted between the first and second arc-shaped covers. This achieves a quick fixation effect between the tops of the first and second arc-shaped covers, greatly improving the installation stability of the first and second arc-shaped covers, avoiding unstable gas protection, and providing practicality for operators.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a disassembly and assembly structure for a welding gas protective cover, including a welding torch connector 1, wherein a conductive nozzle 101 is provided at the bottom end of the welding torch connector 1, and a fixing sleeve 102 is installed on the outside of the welding torch connector 1; a fixing mechanism 2 is provided on the outside of the welding torch connector 1, and a connecting component 3 is provided inside the fixing mechanism 2.

[0026] The fixing mechanism 2 includes a first arc-shaped cover 201 and a second arc-shaped cover 202, which are sleeved on the outside of the welding torch connector 1. The top ends of the first and second arc-shaped covers 201 and 202 are fitted with the inner side of the fixing sleeve 102 with a clearance. A first connecting plate 203 is installed on one side of the first arc-shaped cover 201, and a second connecting plate 204 is installed on one side of the second arc-shaped cover 202. The first and second arc-shaped covers 201 and 202 are in close contact with each other, and the first connecting plate 203 and the second connecting plate 204 are in close contact with each other. A fixed box 205 is symmetrically installed inside both ends of the first connecting plate 203, and a plug plate 206 is symmetrically installed at both ends of the first connecting plate 203. The plug plate 206 is inserted into the fixed box 205. A moving rod 207 is slidably connected inside one side of the fixed box 205. A retractable rod 208 is symmetrically installed inside the fixed box 205. A first telescopic spring 209 is sleeved on the outside of the retractable rod 208. A push plate 210 is installed at one end of the retractable rod 208. A plug block 211 is symmetrically installed on one side of the push plate 210 and is inserted into the plug plate 206. The moving rod 207 can rotate symmetrically on both sides. A movable rod 212 is connected, and one end of the movable rod 212 is rotatably connected to the push plate 210, thereby enabling the first arc-shaped cover 201 and the second arc-shaped cover 202 to be quickly spliced ​​and fixed. This allows the first arc-shaped cover 201 and the second arc-shaped cover 202 to provide stable protection for the welding gun connector 1. The first arc-shaped cover 201 and the second arc-shaped cover 202 can be quickly and easily installed and disassembled, which can greatly reduce the difficulty and time of operation in narrow spaces. Compared with the threaded connection method in the prior art, this is more convenient and improves the cleaning efficiency of the first arc-shaped cover 201 and the second arc-shaped cover 202. To avoid gas path blockage, weakening of gas protection effect, and impact on welding quality, and to provide convenience for workers during use, the second connecting plate 204 has symmetrically opened mounting grooves 213 at both ends, and support rods 214 are symmetrically installed inside the mounting grooves 213. A movable plate 215 is slidably connected between the outer sides of the support rods 214, and one end of the movable rod 207 is fixedly connected to the movable plate 215. When the worker pulls the movable plate 215 to slide on the outer side of the support rod 214, the movable plate 215 drives the movable rod 207 to move, thereby making the movement of the movable rod 207 more stable.

[0027] The connecting assembly 3 includes limiting boxes 301 symmetrically installed inside both sides of the fixing sleeve 102. A fixing tube 302 is installed on one top side of the limiting box 301, and a sliding rod 303 is slidably connected inside the fixing tube 302.

A sliding plate 307 is slidably connected inside one side of the limiting box 301, and toothed blocks 308 are installed on one side of each sliding plate 307. The toothed blocks 308 are inserted into the first arc-shaped cover 201 and the second arc-shaped cover 202. A connecting rod 309 is rotatably connected between the push rod 306 and the sliding plate 307. This enables rapid fixing of the tops of the first arc-shaped cover 201 and the second arc-shaped cover 202, thereby greatly improving the installation stability of the first arc-shaped cover 201 and the second arc-shaped cover 202 and avoiding... To prevent gas protection instability and enhance usability for operators, a sliding groove 310 is provided on one side of the limit box 301, and one side of the slide plate 307 is slidably connected to the sliding groove 310. A pull ring 311 is installed at the top of the slide rod 303. The sliding connection between the slide plate 307 and the sliding groove 310 makes the slide plate 307 move more stably. The pull ring 311 facilitates operation of the slide rod 303. An annular rubber sleeve 312 is installed on the outer side of the welding torch connector 1, and an arc groove 313 is provided on the inner side of the top of the first arc-shaped cover 201 and the second arc-shaped cover 202. The annular rubber sleeve 312 is fitted into the arc groove 313. The compression and fit between the annular rubber sleeve 312 and the arc groove 313 improves the airtightness between the first arc-shaped cover 201 and the second arc-shaped cover 202, preventing gas leakage.

[0028] Working principle: Before using this disassembly and assembly structure for welding gas protective covers, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the worker inserts the first arc-shaped cover 201 and the second arc-shaped cover 202 into the inner side of the bottom of the fixed sleeve 102. At this time, the first arc-shaped cover 201 and the second arc-shaped cover 202 are aligned, the first connecting plate 203 and the second connecting plate 204 are aligned, and the insert plate 206 is inserted into the fixed box 205. Then, the worker pulls the moving rod 207 to slide inside the fixed box 205. At this time, the movement of the moving rod 207 drives the movable rod 212 to rotate. The rotation of the movable rod 212 drives the push plate 210 to move. At this time, the retracting rod 208 and the first telescopic spring 209 retract. By releasing the moving rod 207, the first telescopic spring 209 quickly returns to its original position, thereby allowing the insert block 211 to be inserted into the insert plate 206, thus realizing the connection between the first arc-shaped cover 201 and the second arc-shaped cover 202. The quick splicing and fixing effect of the first arc-shaped cover 201 and the second arc-shaped cover 202 enables the first arc-shaped cover 201 and the second arc-shaped cover 202 to provide stable protection for the welding gun connector 1. The quick and convenient installation and disassembly of the first arc-shaped cover 201 and the second arc-shaped cover 202 can greatly reduce the difficulty and time of operation in narrow spaces. Compared with the threaded connection method in the prior art, it is more convenient, improves the cleaning efficiency of the first arc-shaped cover 201 and the second arc-shaped cover 202, avoids gas path blockage, weakens the gas protection effect, affects the welding quality, and brings convenience to the workers when using it. When the workers pull the moving plate 215 to slide on the outside of the support rod 214, the moving plate 215 drives the moving rod 207 to move, so that the moving rod 207 moves more stably.

[0029] By pulling the sliding rod 303, the slider 305 slides inside the fixed tube 302. At this time, the second telescopic spring 304 contracts, and the slider 305 drives the push rod 306 to move upward. The movement of the push rod 306 causes the connecting rod 309 to rotate. The rotation of the connecting rod 309 pulls the slide plate 307 to slide inside the limit box 301. By releasing the sliding rod 303, and through the reset property of the second telescopic spring 304, multiple sets of toothed blocks 308 can be inserted between the first arc-shaped cover 201 and the second arc-shaped cover 202, thereby achieving rapid connection between the first arc-shaped cover 201 and the second arc-shaped cover 202. The fixed effect between the tops of the two arc-shaped covers 201 and 202 greatly improves the installation stability of the first arc-shaped cover 201 and the second arc-shaped cover 202, avoiding the phenomenon of unstable gas protection and bringing practicality to the staff during use. The sliding connection between one side of the slide plate 307 and the slide groove 310 makes the movement of the slide plate 307 more stable. The design of the pull ring 311 makes it easy for the staff to operate the slide rod 303. The compression and fit between the annular rubber sleeve 312 and the arc-shaped groove 313 improves the airtightness between the first arc-shaped cover 201 and the second arc-shaped cover 202, and avoids gas leakage.
