[0027] The pipe flaring device provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.
[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.
[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.
[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.
[0032] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a pipe flaring device, including a fixing base 1. The bottom edge of the fixing base 1 is provided with mounting ears, which are fixed to the workbench surface in use with bolts. The upper end surface of the fixing base 1 is provided with a liftable base plate 3.
[0033] Specifically, a groove 101 is formed in the middle of the upper end face of the fixed base 1. A drive rod 102 is rotatably installed in the groove 101, and two sliders 2 are fitted to the bottom of the base plate 3. The sliders 2 are slidably placed in the groove 101, and the drive rod 102 is threaded through them. The top ends of the two sliders 2 are hinged to support rods 201, and the top ends of the two support rods 201 are respectively movably supported at both ends of the lower end face of the base plate 3.
[0034] Meanwhile, the slider 2 has a threaded hole 202 in the middle for the drive rod 102 to pass through, and the drive rod 102 has two opposite threaded sections symmetrically arranged. The two sliders 2 are symmetrically arranged on the two opposite threaded sections of the drive rod 102, so that when the drive rod 102 is rotated, the two sliders 2 can be driven to move in a mirror image, thereby adjusting the height of the base plate 3 through the support rod 201. One end of the drive rod 102 extends out of the end of the fixed base 1 and is fixed with a nut to facilitate rotation.
[0035] like Figure 2As shown, two horizontally aligned limiting rings 4 are fixed to the upper surface of the substrate 3. Two support blocks 401 are symmetrically fixed to the bottom of the limiting rings 4. Limiting bolts 402 are vertically installed on the top of the limiting rings 4. A heating ring 5 is installed at one end of the substrate 3. The heating ring 5 is coaxially aligned with the limiting rings 4.
[0036] Cooperate Figure 3 As shown, a sliding rod 6 is horizontally inserted into one end of the fixed base 1 corresponding to the position of the heating ring 5. The sliding rod 6 is connected to a sliding seat 7, and multiple rollers 701 are installed at the lower end of the sliding seat 7.
[0037] like Figure 4 As shown, a conical block 8 is detachably installed at the top of the sliding seat 7. In a specific implementation, a threaded post 801 is fixed at one end of the conical block 8. The threaded post 801 is threadedly installed at the top of the sliding seat 7, and the conical block 8 is horizontally oriented towards the middle of the limiting ring 4.
[0038] The working principle provided by this utility model is that, when using the pipe flaring device, the PE pipe can be placed inside the two limiting rings 4, and the PE pipe can be fixed by three-point abutment by tightening the limiting bolts 402 in conjunction with the two support blocks 401. The fixing effect is good, and it can fix more pipe specifications, making it highly versatile.
[0039] Since the pipe core positions of different specifications of pipes are different after being fixed in the limiting ring 4, the two sliders 2 can be driven to move in a mirror image by rotating the drive rod 102, and the limiting ring 4 on the base plate 3 can be driven to move up and down by the support rod 201, thereby adjusting the height of the PE pipe. After the PE pipes of different specifications are fixed, the height can still be adjusted to make them horizontally aligned with the conical block 8.
[0040] Subsequently, the heating ring 5 can be used to heat the end of the PE pipe, and the sliding seat 7 can be used to drive the tapered block 8 into the heated port of the PE pipe to achieve a uniform flaring effect.
[0041] In summary, this device not only facilitates the installation and fixing of PE pipes of different specifications, but also ensures the flaring effect of the pipe ends, resulting in good overall performance.
[0042] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
