Description

Technical Field

[0001] The utility model relates to the field of hydrogen-oxygen welding devices, in particular to an hydrogen-oxygen gold-silver welding device. Background Art

[0002] Oxyhydrogen welding device, also known as oxyhydrogen welding machine, is a new type of welding machine that uses the high-temperature flame of an oxyhydrogen flame for oxygen welding. The oxyhydrogen welding machine uses water as the medium. Electricity is applied to the water to electrochemically decompose the water to produce hydrogen and oxygen. Hydrogen is used as fuel and oxygen is used as the combustion aid. The oxyhydrogen flame is ignited by a special oxyhydrogen flame gun to form an oxyhydrogen flame to weld the workpiece. The oxyhydrogen welding machine consists of a main unit, a flashback preventer, a connecting hose, a flame gun, and a nozzle.

[0003] Oxyhydrogen welding machines are generally divided into two categories: small and portable, and medium and large. Small oxyhydrogen welding machines are suitable for jewelry welding, jewelry casting and molding, mirror frame welding, thermocouple bimetallic wire welding, motor enameled wire welding, tooth mold repair; plexiglass polishing, acrylic polishing, fishhook welding, quartz glass tube drawing and sealing, quartz glass tube heating, IC chip packaging, fiber optic welding, tungsten wire burning and thinning, and non-ferrous metal welding. Medium and large oxyhydrogen welding machines are commonly used for brazing larger metal workpieces, flame processing of large quartz glass tubes and rods, flame cutting of carbon steel, flame cutting of continuous casting billets, wire drawing and sealing of ampoules in pharmaceutical factories, and waste incineration.

[0004] Jewelry is usually made of gold and silver, so an oxyhydrogen welding machine is needed for welding. Existing oxyhydrogen welding machines usually require the preparation of electrolyte first, followed by opening the sealing cover on the top of the oxyhydrogen welding machine, and turning the sealing cover several times to expose the liquid adding tube. Then, a funnel is placed at the liquid inlet tube, and electrolyte is added to the funnel through the liquid adding device. After adding, the sealing cover is tightened again. This method is more cumbersome and has low work efficiency. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a hydrogen-oxygen gold-silver welding device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an oxyhydrogen gold-silver welding device, comprising an oxyhydrogen welding device body, a liquid inlet pipe being provided on the top of the oxyhydrogen welding device body, and a mixing bin being fixed on the top of the oxyhydrogen welding device body, a limiting block being fixed on the inner wall of the mixing bin, and a vertical rod being movably installed inside the limiting block, a sealing assembly being fixed at the end of the vertical rod, a limiting groove being provided at the bottom end of the inner wall of the mixing bin, a through hole being provided at the bottom end of the inner wall of the limiting groove, and the through hole being communicated with the liquid inlet pipe, a stirring assembly being provided inside the mixing bin, and the sealing assembly comprising a gasket fixed to the end of the vertical rod, the outer wall of the gasket being in contact with the inner wall of the limiting groove.

[0007] By adopting the above technical solution, the problem of inconvenience in adding electrolyte to the existing hydrogen-oxygen welding device is solved. Water is added to the mixing chamber, and then the electrolytic powder is added. After the mixture is cooled, the vertical rod is pulled upward, and the vertical rod squeezes the spring, thereby exposing the through hole. The electrolyte will enter the hydrogen-oxygen welding device body through the through hole. Then, the vertical rod is loosened. Under the action of the spring, the gasket and the rubber sheet are fitted with the limit groove and the through hole to block them, preventing the electrolyte from entering, thereby achieving the purpose of sealing, replacing the existing thread tightening method, and improving work efficiency.

[0008] The utility model is further configured such that the stirring assembly includes a fixed plate fixed to the inner wall of the mixing bin, and a rotating rod is movably installed inside the fixed plate, a plurality of groups of paddles are fixed to the outer wall of the rotating rod, and a handle is fixed to the end of the rotating rod.

[0009] By adopting the above technical solution, the provided handle can facilitate personnel to rotate the rotating rod, and when the rotating rod rotates, it can drive the paddle to rotate, thereby mixing the water and electrolytic powder in the mixing bin, and personnel do not need to use other items to stir them.

[0010] The present invention is further configured such that a plurality of pads are fixed on the bottom of the mixing bin.

[0011] By adopting the above technical solution, the set pads can avoid the problem of the bottom of the mixing bin being suspended, so that the inner wall of the mixing bin can be stable when water is added, avoiding the problem of the liquid inlet pipe being damaged due to the action of gravity in the mixing bin.

[0012] The present invention is further configured such that the bottom end of the inner wall of the mixing bin is inclined, and the bottom end of the inner wall of the mixing bin is inclined toward the limiting groove.

[0013] By adopting the above technical solution, the inner wall of the mixing chamber is tilted, so that the electrolyte can flow to the limiting groove, thereby ensuring that the problem of residual electrolyte in the mixing chamber is avoided.

[0014] The utility model is further configured such that a rubber sheet is fixed to the bottom of the gasket, and the end of the rubber sheet is configured in an arc shape, and the outer wall of the rubber sheet is in contact with the inner wall of the through hole.

[0015] By adopting the above technical solution, the rubber sheet can fit with the inner wall of the through hole, thereby further increasing the sealing performance of the gasket, preventing the electrolyte from entering the interior of the hydrogen-oxygen welding device body through the through hole, and also preventing the problem of gas being discharged through the through hole.

[0016] The utility model is further configured such that a handle is fixed to the end of the vertical rod, a spring is fixed to the bottom of the handle, and the other end of the spring is fixed to the limiting block.

[0017] By adopting the above technical solution, the provided handle can facilitate personnel to pull the vertical rod during use, and the setting of the spring can give the gasket an elastic force, so that the gasket can always fit with the inner wall of the limit groove, preventing the electrolyte from entering the interior of the hydrogen-oxygen welding device body through the limit groove.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The utility model solves the problem of inconvenient addition of electrolyte in the existing oxyhydrogen welding device by providing a mixing chamber, a vertical rod, a spring, a gasket and a rubber sheet. Water is added to the mixing chamber, and then the electrolytic powder is added. After the mixture is cooled, the vertical rod is pulled upward, and the vertical rod squeezes the spring, thereby exposing the through hole. The electrolyte will enter the oxyhydrogen welding device body through the through hole. Then, the vertical rod is loosened. Under the action of the spring, the gasket and the rubber sheet are fitted with the limit groove and the through hole to block them, preventing the electrolyte from entering, thereby achieving the purpose of sealing, replacing the existing thread tightening method, and improving work efficiency.

[0020] 2. The utility model is provided with a stirring assembly, which can conveniently mix water and electrolytic powder. By turning the handle, the rotating rod can drive the paddle to rotate. When the paddle rotates, the water and electrolytic powder can be mixed, and there is no need for personnel to use other items for stirring. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] The following describes an embodiment of the present invention based on its overall structure.

[0028] A hydrogen-oxygen gold-silver welding device, such as Figure 1-Figure 4 As shown, it includes a hydrogen-oxygen welding device body 1, a liquid inlet pipe 6 is provided on the top of the hydrogen-oxygen welding device body 1, and a mixing chamber 2 is fixed on the top of the hydrogen-oxygen welding device body 1, and a limiting block 23 is fixed on the inner wall of the mixing chamber 2, and a vertical rod 4 is movably installed inside the limiting block 23, and a sealing component is fixed at the end of the vertical rod 4, and a limiting groove 24 is provided at the bottom end of the inner wall of the mixing chamber 2, and a through hole 25 is provided at the bottom end of the inner wall of the limiting groove 24, and the through hole 25 is communicated with the liquid inlet pipe 6, and a stirring component is provided inside the mixing chamber 2. The setting of the stirring component can facilitate personnel to mix the electrolytic powder and water. The sealing component package is fixed to the gasket 5 at the end of the vertical rod 4, and the outer wall of the gasket 5 fits with the inner wall of the limiting groove 24. The provided sealing component can prevent the electrolyte from easily entering the hydrogen-oxygen welding device body 1.

[0029] See also Figure 2 and Figure 4 The stirring assembly includes a fixed plate 22 fixed to the inner wall of the mixing bin 2, and a rotating rod 3 is movably installed inside the fixed plate 22. A plurality of paddles 32 are fixed to the outer wall of the rotating rod 3, and a handle 31 is fixed to the end of the rotating rod 3. The handle 31 can be used to facilitate personnel to rotate the rotating rod 3. When the rotating rod 3 rotates, the paddles 32 can be driven to rotate, thereby mixing the water and electrolytic powder in the mixing bin 2, and there is no need for personnel to use other items to stir them.

[0030] See also Figure 4 There are multiple groups of pads 21 fixed at the bottom of the mixing bin 2. The pads 21 can prevent the bottom of the mixing bin 2 from being suspended, so that the inner wall of the mixing bin 2 can be stable when water is added, and the problem of the liquid inlet pipe 6 being damaged due to gravity in the mixing bin 2 can be avoided.

[0031] See also Figure 4 The bottom end of the inner wall of the mixing chamber 2 is inclined, and the bottom end of the inner wall of the mixing chamber 2 is inclined toward the limiting groove 24. The inclined inner wall of the mixing chamber 2 can make the electrolyte flow toward the limiting groove 24, thereby ensuring that the interior of the mixing chamber 2 avoids the problem of residual electrolyte.

[0032] See also Figure 3A handle 41 is fixed to the end of the vertical rod 4, and a spring 7 is fixed to the bottom of the handle 41, and the other end of the spring 7 is fixed to the limit block 23. At this time, the spring 7 is in a squeezed state. The handle 41 provided can facilitate personnel to pull the vertical rod 4 when in use. The setting of the spring 7 can give the gasket 5 an elastic force, so that the gasket 5 can always fit with the inner wall of the limit groove 24, preventing the electrolyte from entering the interior of the hydrogen-oxygen welding device body 1 through the limit groove 24.

[0033] Example 2

[0034] See also Figure 3 The difference between the second embodiment and the first embodiment is that, on the basis of retaining the first embodiment, a rubber sheet 51 is fixed to the bottom of the gasket 5, and the end of the rubber sheet 51 is arranged in an arc shape, and the outer wall of the rubber sheet 51 is in contact with the inner wall of the through hole 25. The rubber sheet 51 can be in contact with the inner wall of the through hole 25, thereby further improving the sealing performance of the gasket 5, preventing the electrolyte from entering the interior of the hydrogen-oxygen welding device body 1 through the through hole 25, and also preventing the problem of gas being discharged through the through hole 25.

[0035] The working principle of the present invention is as follows: when in use, pure water or distilled water is added to the interior of the mixing chamber 2, and then electrolytic powder is added thereto, and the handle 31 is rotated. When the handle 31 is rotated, the paddle 32 is driven to rotate, and the water and the electrolytic powder are mixed when the paddle 32 is rotated. After waiting for cooling, the handle 41 is pulled upward, and the handle 41 is pulled upward to drive the vertical rod 4 to move upward. When the vertical rod 4 moves upward, the spring 7 is squeezed, and at the same time, the gasket 5 is driven to move upward, and the rubber sheet 51 is separated from the inner wall of the through hole 25, and the electrolyte enters the interior of the hydrogen-oxygen welding device body 1 through the through hole 25. When the electrolyte enters the interior of the hydrogen-oxygen welding device body 1, the handle 41 is then released, and the spring 7 drives the vertical rod 4 to reset, the gasket 5 enters the interior of the limiting groove 24, and the rubber sheet 51 enters the interior of the through hole 25 to prevent the electrolyte from entering the interior of the hydrogen-oxygen welding device body 1.
