Description

Technical Field

[0001] This utility model relates to the technical field of welding torch quick-change auxiliary devices, and in particular to a welding torch quick-change auxiliary device. Background Technology

[0002] A welding torch is the part used in the welding process to perform the welding operation. It is a tool used for gas welding, shaped like a gun, with a nozzle at the front that sprays out a high-temperature flame as a heat source. It is flexible, convenient, quick, and the process is simple.

[0003] The inventor discovered during routine welding torch replacement that conventional welding torches connect the gas hose directly to the torch and are secured with clamps. Since the clamps are tightened with screws, tools are required for disassembly, making torch replacement inconvenient and causing problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-change auxiliary device for welding torches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a welding torch quick-change auxiliary device, including a handle, a connecting tube fixedly connected to the bottom of the handle, an adjusting bolt provided on the surface of the handle, a torch head fixedly connected to the surface of the handle, a quick-change device provided on the surface of the connecting tube, the quick-change device including a slot formed on the surface of the connecting tube, a sleeve fitted on the surface of the connecting tube, and a retaining strip fixedly connected inside the sleeve.

[0006] The aforementioned components achieve the following effects: under the action of the locking strip and the locking groove, the sleeve is fixed on the surface of the connecting pipe, thereby achieving the function of quick replacement. When the welding torch needs to be used, the connecting pipe on one side of the welding torch is connected to the gas pipe, thereby allowing gas to enter the interior of the welding torch. The size of the welding torch flame is adjusted by the adjusting bolt, thus achieving the function of using the welding torch.

[0007] Preferably, the surface of the connecting pipe is provided with a circular groove, the inside of the circular groove is provided with a retaining ball, the inner wall of the sleeve is provided with a groove, and the retaining ball is inserted into the inside of the groove.

[0008] The effect achieved by the above components is that, under the action of the ball clamp, the sleeve can be fixed on the surface of the connecting pipe, thereby achieving the function of fixation.

[0009] Preferably, a spring is fixedly connected to the inner wall of the circular groove, and a retaining ball is fixedly connected to the other end of the spring.

[0010] The effect achieved by the above components is that, under the action of the spring, the ball can be inserted into the groove, thereby fixing the sleeve to the surface of the connecting tube.

[0011] Preferably, a push rod is slidably connected inside the groove, and a push plate is fixedly connected to one end of the push rod.

[0012] The effect achieved by the above components is that, under the action of the push rod, the ball can be pushed out of the groove, thereby facilitating the disassembly of the sleeve.

[0013] Preferably, a magnetic ring is fixedly connected to the side of the sleeve, and a magnetic ring is fixedly connected to the bottom of the handle.

[0014] The aforementioned components achieve the following effects: Under the action of the magnetic ring, the sleeve adheres to the surface of the connecting pipe, thus achieving a fixing effect. When a quick replacement of the welding torch is required, the push rod is pressed into the inside of the sleeve, causing the retaining ball to be pushed out from the inside of the groove, pulling the sleeve outward and separating it from the connecting pipe. The new welding torch is then inserted into the inside of the sleeve. Under the action of the retaining strip and the retaining groove, the sleeve is fixed to the surface of the connecting pipe, thus achieving a quick replacement effect. When the retaining groove and the retaining strip are engaged, under the action of the spring, the retaining ball is inserted into the inside of the groove, thus fixing the sleeve to the surface of the connecting pipe. Under the action of the magnetic ring, the sleeve adheres to the surface of the connecting pipe, thus achieving a fixing effect. This assists in the quick replacement of the welding torch.

[0015] Preferably, the surface of the gun head is provided with a protective device, which includes a protective cover fitted onto the surface of the gun head.

[0016] The effect achieved by the above-mentioned components is that, under the action of the protective cover, the gun head can be blocked, preventing foreign objects from entering the inside of the gun head, thereby preventing the phenomenon of foreign objects entering the inside of the gun head.

[0017] Preferably, a retaining ring is fixedly connected inside the protective cover. The retaining ring is made of triangular strip-shaped rubber material, and a baffle is fixedly connected to the surface of the gun head.

[0018] The effect achieved by the above components is that, under the action of the baffle and the retaining ring, the protective cover can be locked onto the surface of the gun head, thereby achieving a fixing effect.

[0019] Preferably, a round rod is fixedly connected inside the protective cover, and a circular ring is fixedly connected to the surface of the round rod.

[0020] The aforementioned components achieve the following effects: Under the action of the round rod and the ring, the round rod is secured inside the gun head, thereby fixing the protective cover. When protection of the gun head is required, after the welding gun has been used and cooled, the protective cover is placed on the surface of the gun head. Under the action of the baffle and the retaining ring, the protective cover can be secured to the surface of the gun head, thus achieving a fixing effect. After the protective cover is placed on the surface of the gun head, the round rod is inserted into the inside of the gun head. Under the action of the ring, the round rod is fixed inside the gun head, thus fixing the protective cover and protecting the gun head.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a quick-change device is provided. When a welding torch needs to be quickly changed, the push rod is pressed into the sleeve, causing the retaining ball to be pushed out of the groove and pulled outward, separating the sleeve from the connecting pipe. The new welding torch is then inserted into the sleeve. Under the action of the retaining strip and the retaining groove, the sleeve is fixed to the surface of the connecting pipe, thus achieving the function of quick change. When the retaining groove and the retaining strip are engaged, the retaining ball is inserted into the groove under the action of the spring, thus fixing the sleeve to the surface of the connecting pipe. Under the action of the magnetic ring, the sleeve is attracted to the surface of the connecting pipe, thus achieving the function of fixation. This assists in the quick change of the welding torch, thereby solving the problem that it is inconvenient to disassemble and replace the welding torch when it is fixed by clamps.
