Description

Technical Field

[0001] This utility model relates to the field of PE water supply pipe welding technology, and in particular to a PE water supply pipe welding device with a limiting mechanism. Background Technology

[0002] In modern water supply systems, PE water supply pipes have become an extremely widely used pipe material due to their excellent corrosion resistance, good flexibility, and relatively economical cost. PE water supply pipes play an important role in water transportation, and welding, as the core process for achieving reliable connection of PE water supply pipes, directly affects the stable operation and service life of the entire water supply system.

[0003] In the existing technology, when welding PE water supply pipes, the user needs to hold one end of the PE pipe and press it against the corresponding position on the welding machine to facilitate the heat fusion of the PE pipe. However, when the user tilts the PE pipe, the heat fusion end of the PE pipe will deviate, resulting in poor welding quality. Therefore, a PE water supply pipe welding device with a limiting mechanism has been designed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a PE water supply pipe welding device with a limiting mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A PE water supply pipe welding device with a limiting mechanism includes a base plate. A plastic welding machine is installed at the top center of the base plate. Limiting mechanisms are installed on both sides of the top of the base plate. Each limiting mechanism includes a side plate fixedly connected to one side of the top of the base plate. Three through holes of different inner diameters are equally spaced in the middle of the side plate. Guide rods are fixedly connected to the four corners of the side plate away from the plastic welding machine. The same moving plate is slidably fitted onto the circumferential surface of two guide rods at the same height. Each moving plate has circular holes at both ends that are adapted to the guide rods. Each guide rod has another... Each end is fixedly connected to a limiting block. Three rectangular blocks are slidably mounted on each of the two movable plates at equal distances, and each rectangular block is adapted to the adjacent through hole. Each of the two movable plates has three rectangular holes adapted to the rectangular blocks. An arc-shaped clamping block is fixedly connected to one end of each rectangular block near the adjacent through hole, and each arc-shaped clamping block is adapted to the adjacent through hole. Anti-slip texture is provided on the inner circumference of each arc-shaped clamping block. The anti-slip texture ensures that when the arc-shaped clamping block squeezes the PE pipe, there is no tendency for the PE pipe to slide relative to the arc-shaped clamping block.

[0007] Preferably, the limiting mechanism further includes four connecting blocks fixedly connected to the four corners on the side of the side plate away from the plastic welding machine. The same sliding rod is fixedly connected between two connecting blocks at the same height. Each rectangular block has an irregular hole near the adjacent sliding rod. Each sliding rod is slidably connected in multiple adjacent irregular holes. A connecting plate is fixedly connected between the same end of the two moving plates. An oblique hole is opened at the bottom of the two connecting plates. The limiting mechanism can realize the positioning and compression of the PE pipe, which facilitates the subsequent welding of the PE pipe.

[0008] Preferably, each of the irregular holes includes a horizontal hole and an oblique hole, and the end of the oblique hole away from the through hole is connected to the horizontal hole.

[0009] Preferably, support legs are fixedly connected to the four corners of the bottom of the base plate, and round rods are fixedly connected to the middle of both sides of the bottom of the base plate. A protrusion is fixedly connected to the bottom of each round rod. A rectangular plate is slidably fitted on the circumferential surface of the two round rods. A round hole adapted to the round rod is opened in the middle of the two rectangular plates. A spring is fitted on the circumferential surface of the two round rods at the bottom of the rectangular plates.

[0010] Preferably, L-shaped tie rods are fixedly connected to both ends of the top of the two rectangular plates, and the top of each L-shaped tie rod slides through the bottom plate and is slidably connected to adjacent oblique holes. Holes adapted to the L-shaped tie rods are opened on the bottom plate, and strip frames are fixedly connected to the middle of the bottom of the two rectangular plates on adjacent sides.

[0011] Preferably, a pressure rod is rotatably connected to one end of the base plate, and a sliding protrusion is fixedly sleeved in the middle of the pressure rod. The two ends of the sliding protrusion are slidably connected to the inner side of the adjacent strip frame. By stepping on the pressure rod, both limiting mechanisms are activated.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing limiting mechanisms and technologies such as rectangular plates, L-shaped pull rods, and pressure rods, the PE pipe is inserted into the corresponding perforation and brought close to the plastic welding machine. Then, the operator steps on one end of the pressure rod, which drives the two limiting mechanisms to operate, positioning the PE pipe and pushing it towards one side of the plastic welding machine. This ensures that the PE pipe is fully heat-melted without shifting, effectively solving the problems mentioned in the background technology. This ensures that the pipe is accurately positioned during welding, avoids shifting, and guarantees uniform heating and sufficient and consistent heat fusion at the welded part, thereby significantly improving the strength and sealing of the welded joint.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A PE water supply pipe welding device with a limiting mechanism includes a base plate 1. A plastic welding machine 4 is installed at the top center of the base plate 1. Limiting mechanisms 3 are installed on both sides of the top of the base plate 1. Each limiting mechanism 3 includes a side plate 301 fixedly connected to one side of the top of the base plate 1. Three through holes 302 with different inner diameters are equally spaced in the middle of the side plate 301. Guide rods 303 are fixedly connected to the four corners of the side plate 301 away from the plastic welding machine 4. The same moving plate 304 is slidably fitted on the circumferential surface of two guide rods 303 at the same height. Each moving plate 304 has openings at both ends that are connected to the guide rods 302. The guide rod 303 has a matching round hole, and a limit block is fixedly connected to the other end of each guide rod 303. Three rectangular blocks 309 are slidably sleeved on the two moving plates 304 at equal distances. Each rectangular block 309 is matched with the adjacent through hole 302. Three rectangular holes that match the rectangular blocks 309 are opened on the two moving plates 304. An arc-shaped clamping block 311 is fixedly connected to one end of each rectangular block 309 that is close to the adjacent through hole 302. Each arc-shaped clamping block 311 is matched with the adjacent through hole 302. Anti-slip texture is provided on the inner circumference of each arc-shaped clamping block 311.

[0021] In this utility model, the limiting mechanism 3 also includes four connecting blocks 307 fixedly connected to the four corners of the side plate 301 away from the plastic welding machine 4. The same sliding rod 308 is fixedly connected between two connecting blocks 307 at the same height. Each rectangular block 309 has an irregular hole 310 near the adjacent sliding rod 308. Each sliding rod 308 is slidably connected in multiple adjacent irregular holes 310. A connecting plate 305 is fixedly connected between the same end of the two moving plates 304. An oblique hole 306 is opened at the bottom of the two connecting plates 305. Through the setting of the limiting mechanism 3, the PE pipe is positioned and squeezed towards one side of the plastic welding machine 4.

[0022] In this utility model, each irregular hole 310 includes a horizontal hole and an oblique hole, and the end of the oblique hole away from the through hole 302 is connected to the horizontal hole. By setting the irregular hole 310, when the limiting mechanism 3 is in operation, the arc-shaped clamping block 311 moves closer to the nearby through hole 302 and squeezes the PE pipe toward the side of the plastic welding machine 4.

[0023] In this utility model, support legs 2 are fixedly connected to the four corners of the bottom of the base plate 1. Round rods 501 are fixedly connected to the middle of both sides of the bottom of the base plate 1. A protrusion is fixedly connected to the bottom of each round rod 501. A rectangular plate 5 is slidably fitted on the circumferential surface of the two round rods 501. A round hole adapted to the round rod 501 is opened in the middle of the two rectangular plates 5. A spring 502 is fitted on the circumferential surface of the two round rods 501 at the bottom of the rectangular plate 5. The setting of the spring 502 makes the two rectangular plates 5 at a high position when the pressure rod 6 is not under force.

[0024] In this utility model, L-shaped tie rods 503 are fixedly connected to both ends of the top of the two rectangular plates 5. The top of each L-shaped tie rod 503 slides through the bottom plate 1 and is slidably connected in the adjacent oblique holes 306. Holes adapted to the L-shaped tie rods 503 are opened on the bottom plate 1. Strip frames 504 are fixedly connected to the middle of the bottom of the two rectangular plates 5 on the side that are close to each other.

[0025] In this utility model, a pressure rod 6 is rotatably connected to one end of the base plate 1, and a sliding protrusion 601 is fixedly sleeved in the middle of the pressure rod 6. The two ends of the sliding protrusion 601 are slidably connected to the inner side of the adjacent strip frame 504. The descent of one end of the pressure rod 6 can cause the two rectangular plates 5 to descend with the L-shaped pull rod 503.

[0026] Working principle: When in use, place the device flat on the ground, turn on the plastic welding machine 4 to heat it up, insert one end of the two PE pipes to be welded into the corresponding through holes 302 of the limiting mechanisms 3 on both sides, and make the close ends of the two PE pipes contact the two sides of the plastic welding machine 4. At this time, the operator steps on one end of the pressure rod 6, causing the pressure rod 6 to rotate and descend. Through the cooperation of the sliding protrusion 601 and the strip frame 504, the two rectangular plates 5 descend along with the L-shaped pull rod 503, compressing the spring 502. When the L-shaped pull rod 503 descends, due to the L-shaped pull rod 502... The top of each of the three parts is slidably connected in the inclined hole 306, so that the two connecting plates 305 and the two moving plates 304 of the limiting mechanism 3 on both sides move toward one side of the side plate 301. During the movement, the sliding rod 308 slides in the irregular hole 310. Under the action of the irregular hole 310, each arc-shaped clamping block 311 moves toward the adjacent through hole 302. Through the setting of the arc-shaped clamping block 311, the PE pipe is squeezed and limited, and squeezed toward one side of the plastic welding machine 4, so that the end of the two PE pipes to be welded is fully melted, which makes it easier to squeeze the PE pipe toward the plastic welding machine 4 without manual intervention, thus reducing the workload.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
