Description

Technical Field

[0001] This utility model relates to the field of electrofusion pipe fitting construction, and in particular to a clamp for the rapid installation of electrofusion pipe fittings. Background Technology

[0002] Electrofusion fittings are plastic pipe fittings that can be connected by melting the material using the temperature generated by an electric current. The fitting contains heating wires inside and terminals on the outside. To connect the pipe and fitting, the pipe and fitting are inserted into each other, the electrofusion clamp is installed, the power is turned on, and the switch is activated for welding. After welding, the fitting is allowed to cool naturally without applying any external force. The clamp can only be removed after cooling is complete. The heating and cooling processes are crucial factors affecting the strength of the electrofusion weld. Furthermore, the heating and cooling times significantly influence the welding speed. While the heating time is relatively fixed, the difference in cooling time directly determines the welding efficiency. Typically, during installation, the welding clamp is removed only after the pipe and electrofusion fitting connection has cooled down, which impacts welding efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-2 As shown in the figure, an embodiment of this utility model provides a clamp for quick installation of electrofusion pipe fittings, including a clamp body 1, a snap-fit ​​part 3, a snap-fit ​​connector 4, and a hanging lug 5. The clamp body 1 is an arc-shaped, flat, strip-like structure; specifically, the clamp body 1 can be generally configured as a non-closed ring for fitting over the outside of the pipe.

[0027] Please see Figure 1-2 In one embodiment of this utility model, the snap-fit ​​part 3 is fixedly connected to one end of the clamp body 1. A limiting groove 31 is formed within the snap-fit ​​part 3. Specifically, the snap-fit ​​part 3 may include an inner layer, an outer layer, and a connecting layer. The connecting layer is used for fixed connection with the clamp body 1. The inner layer and outer layer are respectively fixedly disposed at both ends of the connecting layer. It may also include a sealing layer, which is fixedly connected to the sides of the inner layer, outer layer, and connecting layer to enclose and form the limiting groove 31. In this case, the end of the limiting groove 31 away from the clamp body 1 and one side are connected to the outside. A plurality of limiting protrusions 32 are provided at the end of the limiting groove 31 away from the clamp body 1. Specifically, the limiting protrusions 32 are disposed on the inner surface of the outer layer. The limiting protrusions 32 can be a plurality of triangular structures for engaging the snap-fit ​​connector 4. The inner wall of the snap-fit ​​part 3 may be arc-shaped and coaxially arranged with the arc-shaped inner wall of the clamp body 1 to better fit the pipe surface.

[0028] Please see Figure 1-2In one embodiment of this utility model, the snap-fit ​​connector 4 is fixedly connected to the other end of the clamp body 1, and the inner wall of the snap-fit ​​connector 4 is coplanar with the inner wall of the clamp body 1. A plurality of snap-fit ​​protrusions 41 are fixedly provided on the outer surface of the snap-fit ​​connector 4. The snap-fit ​​protrusions 41 can be a plurality of triangular protrusion structures; specifically, the snap-fit ​​protrusions 41 can be inclined. In use, the snap-fit ​​connector 4 is inserted into the limiting groove 31, and the two ends of the clamp body 1 are snapped together by the limiting protrusions 32 in the limiting groove 31 and the snap-fit ​​protrusions on the snap-fit ​​connector 4.

[0029] Please see Figure 1-2 In one embodiment of this utility model, the outer wall of the connector 4 near the clamp body 1 may be fixedly provided with a mounting ear 2, which makes it easier to insert the connector 4 into the limiting groove 31. The end of the connector 4 away from the clamp body 1 is provided with a guide slope. The end of the guide slope near the inner wall is first inserted into the limiting groove 31 to guide the connector 4 during insertion into the limiting groove 31, reducing the difficulty of insertion.

[0030] Please see Figure 1-2 In one embodiment of this utility model, a hanging ear 5 is fixedly provided on the clamp body 1 or the snap-fit ​​part 3, that is, the hanging ear 5 can be fixedly connected to the clamp body 1 or to the snap-fit ​​part 3. As an example, the hanging ear 5 is fixedly connected to the sealing layer on the side of the snap-fit ​​part 3. The hanging ear 5 has a through hole to allow the terminal of the electrofusion fitting to be inserted during use, making the device more stable. Further, a connecting part is provided between the hanging ear 5 and the clamp body 1 or the snap-fit ​​part 3, and the connecting part is set at an angle with the hanging ear 5 and the clamp body 1 or the snap-fit ​​part 3. This allows the hanging ear 5 to extend outward relative to the clamp body 1, facilitating the fitting operation during use.

[0031] The working principle of this utility model:

[0032] The clamp body 1, clamping part 3, clamping connector 4, mounting ear 2, and hanging ear 5 can be an integral structure, made of PE or PP material, and integrally injection molded by an injection molding machine. In use, first, the through hole on the hanging ear 5 is fitted onto the terminal of the electrofusion fitting, and the clamp body 1 is fitted onto the pipe connected to the electrofusion fitting. After the pipe and the electrofusion fitting are inserted and fused, the clamping connector 4 is inserted into the limiting groove 31 by applying force to the mounting ear 2. The clamping protrusion 41 and the limiting protrusion 32 are engaged to achieve the connection and fixation of the electrofusion fitting and the pipe at the connection position. The process of inserting the clamp connector 4 into the limiting groove 31 can be achieved by using a tool (such as pliers) to apply external force directly through the end of the limiting groove 31 (away from the clamp body 1). During insertion, due to the force applied to the outside of the clamp connector 4, the clamp connector 4 will be tightly attached to the inner layer of the clamping part 3. After the clamp is tightened and the clamp connector 4 is loosened, due to the force of the pipe and its own outward restoration, the end of the clamp connector 4 away from the clamp body 1 abuts against the inner wall of the outer layer of the clamping part 3, and cooperates with the limiting protrusion 32 on it to achieve clamping and fixing. Alternatively, the clamp connector 4 can be offset from the limiting groove 31, and then the clamp connector 4 can be pushed into the limiting groove 31 through the opening on the side of the clamping part 3 to achieve clamping.

[0033] After the electrofusion fitting and pipe are socketed and fused, this device can quickly clamp the pipe in place, allowing the welding clamps to be removed immediately. This eliminates the need to wait for the welded area to cool completely before proceeding with subsequent operations, reducing cooling time and improving welding and installation efficiency. Previously, removing the welding clamps after the welded area had cooled relied on manual judgment. Removing the clamps before proper cooling could lead to pipe leaks due to insufficient cooling after connection. The clamps provided in this application directly fix the pipe after welding, eliminating the cooling step and preventing such issues, effectively ensuring welding quality.
