Description

Technical Field

[0001] This utility model relates to the technical field of PE water pipe heat fusion connection equipment, and in particular to a PE water pipe heat fusion connection equipment. Background Technology

[0002] PE water pipes are a type of water supply pipe made from polyethylene material. Due to the material properties of polyethylene, PE water pipes have strong strength and corrosion resistance. When using PE water pipes, multiple pipes often need to be connected and assembled. In order to maintain good sealing at the joints of PE water pipes, special PE water pipe heat fusion connection equipment is often used.

[0003] To address this, patent specification CN211074749U discloses a hot-melt machine for connecting PE water pipes, relating to the field of hot-melt machines. This hot-melt machine for connecting PE water pipes includes a housing. A switch and a digital display are fixedly connected to the front of the housing. A heat sink is fixedly connected to the right side of the housing, with heat dissipation holes on its front. A heat-resistant plate is fixedly connected to the right side of the heat sink, and a heating plate is fixedly connected to the right side of the heat-resistant plate. A protective plate is fixedly connected to the upper surface of the heat-resistant plate. Equally spaced melting die heads are fixedly connected to the upper and bottom surfaces of the heating plate. A fixing block is fixedly connected to the left side of the housing. This hot-melt machine for connecting PE water pipes achieves a simple structure through the fixing block and slots, avoiding the inability to secure the hot-melt machine. The cooperation of the heat-resistant plate and the protective plate protects the heating plate, preventing burns during use. While the above-mentioned PE water pipe hot-melt connection equipment has good hot-melt performance, some problems still exist:

[0004] When the aforementioned PE water pipe heat fusion connection equipment is used to connect larger diameter PE water pipes, the connection is often difficult to operate due to the weight of the large diameter PE water pipes, resulting in misalignment of the connection. Utility Model Content

[0005] The purpose of this invention is to provide a PE water pipe heat fusion connection device to solve the defect of misalignment in existing PE water pipe heat fusion connection devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a PE water pipe hot-melt connection device, including a base and a fixed sleeve. A bracket is fixedly connected to the upper inner side of the base, and a fixed sleeve is fixedly connected to the top of the bracket. Sliding rods are fixedly connected to both ends of the inner side of the bracket. A connecting screw is rotatably connected to the middle position of the inner side of the bracket. A double-sided hot-melt device is flipped and connected to the middle position of the outer side wall of the sliding rod. One end of the connecting screw passes through to one side of the bracket and is fixedly connected to one side of the locking structure. A clamping structure is fixedly connected to the top of the fixed sleeve. The clamping structure includes a fixed ring, a movable ring, a fastening screw, a guide rod, a guide groove, a hinge rod, and a clamping seat. The fixed ring is fixedly connected to both sides of the outer side wall of the fixed sleeve and the movable sleeve. Some parts of the fixed sleeve are provided with movable sleeves.

[0007] In use, clean and trim the joints of the two sets of PE water pipes to be connected, enabling them to be joined. Then, insert the two sets of PE water pipes into the fixed sleeve and the movable sleeve respectively for support. By rotating the connecting screw, the movable sleeve moves one set of PE water pipes, causing one heating side of the double-sided heat fusion device to insert into the PE water pipe for melting. As the connecting screw rotates, the movable sleeve pushes the double-sided heat fusion device so that the other heating side inserts into the fixed sleeve for heat melting of the PE water pipe joints. After the PE water pipe joints have been heat-melted for a certain period of time, rotate the connecting screw in the opposite direction to reset the movable sleeve and flip the double-sided heat fusion device so that it separates from the middle position between the fixed sleeve and the movable sleeve. Then, rotate the connecting screw again to connect the heat-melted areas of the two sets of PE water pipes. After the joint temperature cools down, the two sets of PE water pipes are sealed together.

[0008] Preferably, a movable ring is fitted on the outer side of both the fixed sleeve and the movable sleeve. A fastening screw is threaded to the top of the movable ring. Guide rods pass through both ends of the movable ring. Guide grooves are provided on the outer side walls of both the fixed sleeve and the movable sleeve. A hinge rod is hinged to one side of both the fixed ring and the movable ring. A clamping seat is hinged to one end of the hinge rod.

[0009] Preferably, the fixed ring and the fastening screw are in a rotating structure, and the guide rod and the movable ring are in a sliding structure, so that the hinge rod can be pushed and pulled stably.

[0010] Preferably, the movable ring sleeve and the fixed sleeve have a sliding structure, and the guide groove is distributed in a ring on the outer side wall of both the fixed sleeve and the movable sleeve, so that the movable ring sleeve can slide smoothly.

[0011] Preferably, the locking structure includes an extension rod, an external threaded sleeve, an anti-slip pad, a dividing groove, and a fastening nut. One side of the extension rod is fixedly connected to one side of the connecting screw, and the other side of the bracket is fixedly connected to the external threaded sleeve. One side of the outer wall of the extension rod extends into the interior of the external threaded sleeve. One side of the inner wall of the external threaded sleeve is fixedly connected to the anti-slip pad. A dividing groove is formed on one side of the outer wall of the external threaded sleeve, and a fastening nut is fitted on the outer side of the external threaded sleeve.

[0012] Preferably, the cross-sectional area of ​​the outer diameter of the extension rod is smaller than the cross-sectional area of ​​the inner diameter of the external threaded sleeve, and the external threaded sleeve and the fastening nut are connected by a thread, so that the external threaded sleeve can be contracted inward.

[0013] Preferably, several anti-slip pads are fixedly connected to the inner wall of the external threaded sleeve, and the several anti-slip pads are arranged in a ring on the inner wall of the external threaded sleeve, so as to make the clamping of the extension rod more secure.

[0014] Compared with the existing technology, the beneficial effects of this utility model are: by rotating the fastening screw, several clamping seats are used to clamp the outer wall of the PE water pipe, thereby greatly improving the application range of the equipment. At the same time, by fixing the extension rod on one side of the connecting screw and locking it by rotating the fastening nut, the loosening of the PE water pipe during connection is avoided, which would affect the heat fusion effect.

[0015] 1. Rotate the fastening screw to make the moving ring slide along the guide rod. Since the fixed ring and the moving ring are connected by several hinge rods on the inner side, by controlling the forward and reverse rotation of the fastening screw, the hinge rods push and pull the clamping seat, so as to fasten and clamp PE water pipes of different diameters.

[0016] 2. When the connecting screw rotates, the two sets of PE water pipes are tightly connected and then tighten the fastening nut towards the outside of the dividing groove. This causes the external threaded sleeve to retract inward and clamp the inner extension rod, thus preventing the connecting screw from loosening and reversing, which could lead to loosening of the PE water pipe heat fusion connection.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a PE water pipe heat fusion connection device, including a base 1 and a fixed sleeve 3. A bracket 2 is fixedly connected to the upper inner side of the base 1, and a fixed sleeve 3 is fixedly connected to the top of the bracket 2. Slide rods 6 are fixedly connected to both ends of the inner side of the bracket 2. A connecting screw 8 is rotatably connected to the middle position of the inner side of the bracket 2. A double-sided heat fusion device 7 is flipped and connected to the middle position of the outer side wall of the slide rod 6. A movable sleeve 5 is provided on some parts of the fixed sleeve 3. A clamping structure 4 is fixedly connected to the top of the fixed sleeve 3. The clamping structure 4 includes a fixed ring 401, a movable ring 402, a fastening screw 403, a guide rod 404, a guide groove 405, a hinge rod 406, and a clamping seat 407. The fixed ring 401 is fixedly connected to the fixed sleeve 3 and the movable sleeve 5. On both sides of the outer wall, a movable ring 402 is fitted on the outer side of the fixed sleeve 3 and the movable sleeve 5. The top of the movable ring 402 is threaded with a fastening screw 403. Guide rods 404 pass through both ends of the movable ring 402. Guide grooves 405 are opened on the outer walls of the fixed sleeve 3 and the movable sleeve 5. A hinge rod 406 is hinged to one side of the fixed ring 401 and the movable ring 402. A clamping seat 407 is hinged to one end of the hinge rod 406. The fixed ring 401 and the fastening screw 403 have a rotating structure. The guide rod 404 and the movable ring 402 have a sliding structure. The movable ring 402 and the fixed sleeve 3 and the movable sleeve 5 have a sliding structure. The guide grooves 405 are distributed in a ring on the outer walls of the fixed sleeve 3 and the movable sleeve 5.

[0025] See attached document Figure 1 , Figure 2 ,Figure 3 and Figure 4 When using this hot-melt connection equipment, two sets of PE water pipes are inserted into the fixed sleeve 3 and the movable sleeve 5 respectively, and the joint surfaces of the PE water pipes are hot-melted under the action of the double-sided hot-melt device 7. Since the diameters of PE water pipes of different specifications are not the same, in order to avoid the PE water pipes from slipping and reducing the hot-melt effect during the jointing, a fixing ring 401 is fixed on the outside of both the fixed sleeve 3 and the movable sleeve 5. After the PE water pipe is inserted into the fixed sleeve 3 and the movable sleeve 5, the fastening screw 403 is rotated, so that the movable ring 402 connected to it by the thread slides along the guide rod 404. Since the inner sides of the fixed ring 401 and the movable ring 402 are annularly hinged with several hinge rods 406, by controlling the forward and reverse rotation of the fastening screw 403, the hinge rods 406 push and pull the clamping seat 407, so as to fasten and clamp PE water pipes of different diameters.

[0026] One end of the connecting screw 8 extends through to one side of the bracket 2 and is fixedly connected to one side of the locking structure 9. The locking structure 9 includes an extension rod 901, an external threaded sleeve 902, an anti-slip pad 903, a dividing groove 904, and a fastening nut 905. One side of the extension rod 901 is fixedly connected to one side of the connecting screw 8, and the other side of the bracket 2 is fixedly connected to the external threaded sleeve 902. One side of the outer wall of the extension rod 901 extends into the interior of the external threaded sleeve 902, and one side of the inner wall of the external threaded sleeve 902 is fixedly connected to... The external threaded sleeve 902 has an anti-slip pad 903 attached to it. A dividing groove 904 is provided on one side of the outer wall of the external threaded sleeve 902. A fastening nut 905 is fitted on the outer side of the external threaded sleeve 902. The cross-sectional area of ​​the outer diameter of the extension rod 901 is smaller than the cross-sectional area of ​​the inner diameter of the external threaded sleeve 902. The external threaded sleeve 902 and the fastening nut 905 are connected by a thread. Several anti-slip pads 903 are fixedly connected to the inner wall of the external threaded sleeve 902, and the several anti-slip pads 903 are distributed in a ring on the inner wall of the external threaded sleeve 902.

[0027] See attached document Figure 3 and Figure 5 When two sets of PE water pipes are joined after heat fusion, they need to be tightly connected. To prevent the threaded connection between the connecting screw 8 and the moving sleeve 5 from loosening, which could lead to displacement or loosening of the heat-fused connection of the two sets of PE water pipes, an extension rod 901 is fixed on one side of the connecting screw 8. When the connecting screw 8 rotates, the two sets of PE water pipes are tightly connected and then tightened towards the outside of the dividing groove 904 with the fastening nut 905. This causes the area of ​​the external threaded sleeve 902, which is divided by several dividing grooves 904, to gradually shrink inward and the anti-slip pad 903 to fasten and clamp the inner extension rod 901. This prevents the connecting screw 8 from loosening and reversing, which could lead to loosening of the heat-fused connection of the PE water pipes.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
