[0031] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] In household appliances, double-wire clamp fasteners are commonly used to fix pipes, such as water pipes. This type of fastener is an elastic one-piece design and has directionality. However, when fastening the pipe with the fastener, the pipe must first be passed through the clamp in the correct assembly direction, and then the clamp is moved to the corresponding position of the pipe to achieve the function of fastening the water pipe. Therefore, in the production of household appliances, there are certain requirements for the assembly sequence of fasteners, which leads to low assembly efficiency and is not conducive to the later maintenance of the pipe after the assembly is completed.

[0033] Based on the above technical problems, the embodiment of the utility model discloses a fastening device, which may include a first clamp 1, a second clamp 2, a rotating shaft 3 and a detachable connection component 4, wherein the first clamp 1 and the second clamp 2 cooperate to form an ellipse, wherein one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3, so that a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the detachable connection component 4 connects the other end of the first clamp 1 and the other end of the second clamp 2, so that the first clamp 1 and the second clamp 2 fasten the pipe. Thus, through the cooperation of the split structure and the detachable connection component 4, the assembly and disassembly efficiency of the fastening device is improved, and the fastening degree of the pipe is improved while facilitating the later maintenance of the pipe.

[0034] Reference Figure 1 As shown, an embodiment of the utility model provides a fastening device, which includes a first clamp 1, a second clamp 2, a rotating shaft 3 and a detachable connection component 4, wherein the first clamp 1 and the second clamp 2 cooperate to form an ellipse, wherein one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3, so that a space for pipe installation is formed between the first clamp 1 and the second clamp 2. For example, one end of the second clamp 2 is embedded in one end of the first clamp 1, and is gap-matched with the first clamp 2, so that the rotating shaft 3 axially penetrates the first clamp 1 and the second clamp 2 to form a rotating connection. In addition, the detachable connection component 4 connects the other end of the first clamp 1 and the other end of the second clamp 2, so that the first clamp 1 and the second clamp 2 fasten the pipe.

[0035] In the embodiment of the utility model, the fastening device is mainly used to fasten pipes that need to be fixed in household appliances. For example, it can be used for drainage, pumping, exhaust, and air extraction, etc., which are not limited here. The fastening device may include a first clamp 1, a second clamp 2, a rotating shaft 3, and a detachable component. Among them, the two ends of the first clamp 1 are respectively matched with the two ends of the second clamp 2 to form a ring structure with an elliptical radial cross section to fix the pipe. The split fastening device can facilitate the assembly between the pipe and the fastening device, so that the fastening device does not need to be adjusted to an appropriate angle for the pipe to pass axially, thereby improving the assembly efficiency of the fastening device. Among them, one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3. That is to say, a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the corresponding installation opening angle is adjustable, so that it is easier to assemble the first clamp 1 and the second clamp 2 to the pipe.

[0036] During the assembly process of the pipeline and the fastening device, the first clamp 1 can be adjusted around the rotating axis 3; or, the second clamp 2 can be adjusted around the rotating axis 3; or, the first clamp 1 and the second clamp 2 can be adjusted around the rotating axis 3 at the same time, so as to achieve the assembly of the fastening device to the pipeline along the radial direction of the pipeline.

[0037] The detachable connection component 4 is mainly used to realize the detachable connection between the other end of the first clamp 1 and the other end of the second clamp 2. That is to say, the detachable connection component 4 is located between the first clamp 1 and the second clamp 2 to form a space for pipe installation, corresponding to the installation opening. Thus, the connection between the first clamp 1 and the second clamp 2 and the closure of the installation opening are realized through the detachable connection component 4, thereby realizing the fastening of the pipe and improving the convenience of disassembly and assembly of the fastening device, so as to facilitate the maintenance of the pipe later.

[0038] Furthermore, when the first clamp 1 and the second clamp 2 match in shape to form an ellipse, the short axis of the corresponding ellipse will form a pressure contact with the pipe in advance, thereby improving the fastening degree of the fastening device to the pipe.

[0039] In some embodiments, the cross-sectional shape of the first clamp 1 may be the arc length corresponding to half of an ellipse, and correspondingly, the cross-sectional shape of the second clamp 2 may be consistent with that of the first clamp 1. For example, the connecting lines at both ends of the first clamp 1 coincide with the major axis corresponding to the ellipse, the connecting lines at both ends of the second clamp 2 coincide with the major axis corresponding to the ellipse, and the connecting line between the center position of the first clamp 1 and the center position of the second clamp 2 coincides with the minor axis corresponding to the ellipse.

[0040] In other embodiments, the connecting lines at both ends of the first clamp 1 coincide with the short axis of the ellipse, the connecting lines at both ends of the second clamp 2 coincide with the corresponding short axis of the ellipse, and the connecting line between the center position of the first clamp 1 and the center position of the second clamp 2 coincides with the corresponding long axis of the ellipse.

[0041] When installing the fastening device and the pipeline, the first clamp 1 and the second clamp 2 can be separated from each other, so as to reserve enough installation space for the pipeline. Then, the first clamp 1 and the second clamp 2 are installed along the radial direction of the pipeline, so that the first clamp 1 and the second clamp 2 surround the pipeline. Figure 3 As shown, the other end of the first clamp 1 and the other end of the second clamp 2 are finally connected by the detachable connection component 4, so as to achieve the fastening of the pipeline. In some embodiments, a part of the detachable connection component 4 can be installed on the first clamp 1, and another part of the detachable connection component 4 can be installed on the second clamp 2.

[0042] In summary, the embodiment of the utility model provides a fastening device, which may include a first clamp 1, a second clamp 2, a rotating shaft 3 and a detachable connection component 4, wherein the first clamp 1 and the second clamp 2 cooperate to form an ellipse, wherein one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3, so that a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the detachable connection component 4 connects the other end of the first clamp 1 and the other end of the second clamp 2, so that the first clamp 1 and the second clamp 2 fasten the pipe. Thus, the assembly and disassembly efficiency of the fastening device is improved through the cooperation of the split structure and the detachable connection component 4, and the fastening degree of the pipe is improved while facilitating the later maintenance of the pipe.

[0043] Reference Figure 2 and Figure 3As shown, an embodiment of the utility model provides a fastening device, which may include a first hoop 1, a second hoop 2, a rotating shaft 3 and a detachable connection component 4, wherein the first hoop 1 and the second hoop 2 cooperate to form an ellipse, wherein one end of the first hoop 1 and one end of the second hoop 2 are rotatably connected through the rotating shaft 3, so that a space for pipe installation is formed between the first hoop 1 and the second hoop 2, and the detachable connection component 4 connects the other end of the first hoop 1 and the other end of the second hoop 2, so that the first hoop 1 and the second hoop 2 fasten the pipe. A first rib 5 is provided along the inner side of the first hoop 1. Alternatively, a second rib 6 is provided along the inner side of the second hoop 2. Alternatively, a first rib 5 is provided along the inner side of the first hoop 1, and a second rib 6 is provided along the inner side of the second hoop 2.

[0044] In the embodiment of the utility model, the fastening device is mainly used to fasten pipes that need to be fixed in household appliances. For example, it can be used for drainage, pumping, exhaust, and air extraction, etc., which are not limited here. The fastening device may include a first clamp 1, a second clamp 2, a rotating shaft 3, and a detachable component. Among them, the two ends of the first clamp 1 are respectively matched with the two ends of the second clamp 2 to form a ring structure with an elliptical radial cross section to fix the pipe. The split fastening device can facilitate the assembly between the pipe and the fastening device, so that the fastening device does not need to be adjusted to an appropriate angle for the pipe to pass axially, thereby improving the assembly efficiency of the fastening device. Among them, one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3. That is to say, a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the corresponding installation opening angle is adjustable, so that it is easier to assemble the first clamp 1 and the second clamp 2 to the pipe.

[0045] During the assembly process of the pipeline and the fastening device, the first clamp 1 can be adjusted around the rotating axis 3; or, the second clamp 2 can be adjusted around the rotating axis 3; or, the first clamp 1 and the second clamp 2 can be adjusted around the rotating axis 3 at the same time, so as to achieve the assembly of the fastening device to the pipeline along the radial direction of the pipeline.

[0046] The detachable connection component 4 is mainly used to realize the detachable connection between the other end of the first clamp 1 and the other end of the second clamp 2. That is to say, the detachable connection component 4 is located between the first clamp 1 and the second clamp 2 to form a space for pipe installation, corresponding to the installation opening. Thus, the connection between the first clamp 1 and the second clamp 2 and the closure of the installation opening are realized through the detachable connection component 4, thereby realizing the fastening of the pipe and improving the convenience of disassembly and assembly of the fastening device, so as to facilitate the maintenance of the pipe later.

[0047] Furthermore, when the first clamp 1 and the second clamp 2 match in shape to form an ellipse, the short axis of the corresponding ellipse will form a pressure contact with the pipe in advance, thereby improving the fastening degree of the fastening device to the pipe.

[0048] In some embodiments, the cross-sectional shape of the first clamp 1 may be the arc length corresponding to half of an ellipse, and correspondingly, the cross-sectional shape of the second clamp 2 may be consistent with that of the first clamp 1. For example, the connecting lines at both ends of the first clamp 1 coincide with the major axis corresponding to the ellipse, the connecting lines at both ends of the second clamp 2 coincide with the major axis corresponding to the ellipse, and the connecting line between the center position of the first clamp 1 and the center position of the second clamp 2 coincides with the minor axis corresponding to the ellipse.

[0049] In other embodiments, the connecting lines at both ends of the first clamp 1 coincide with the short axis of the ellipse, the connecting lines at both ends of the second clamp 2 coincide with the corresponding short axis of the ellipse, and the connecting line between the center position of the first clamp 1 and the center position of the second clamp 2 coincides with the corresponding long axis of the ellipse.

[0050] In some embodiments, the first rib 5 is used to improve the overall strength of the first clamp 1 and can be used to press against the pipe. Since the first rib 5 is located on the inner side of the first clamp 1, the first rib 5 is pressed against the pipe in advance during the process of tightening the pipe. Compared with the case where the first clamp 1 is directly pressed against the pipe, the pressure contact area between the first rib 5 and the pipe is greatly reduced, thereby improving the tightness of the first rib 5 fixing the pipe.

[0051] In other embodiments, the second rib 6 is used to improve the overall strength of the second clamp 2 and can be used to press against the pipe. Since the second rib 6 is located on the inner side of the second clamp 2, the second rib 6 forms a pressure contact with the pipe in advance during the process of tightening the pipe. Compared with the case where the second clamp 2 directly presses against the pipe, the pressure contact area between the second rib 6 and the pipe is greatly reduced, thereby improving the tightness of the second rib 6 fixing the pipe.

[0052] In some other embodiments, a first rib 5 is provided along the inner side of the first hoop 1, and a second rib 6 is provided along the inner side of the second hoop 2. The first rib 5 is used to improve the overall strength of the first hoop 1, and can be used to press against the pipe. The second rib 6 is used to improve the overall strength of the second hoop 2, and can be used to press against the pipe. Since the first rib 5 is located on the inner side of the first hoop 1, and the second rib 6 is located on the inner side of the second hoop 2, in the process of fastening the pipe, the first rib 5 and the second rib 6 are pre-pressed against the pipe. Compared with the case where the first hoop 1 and the second hoop 2 are directly pressed against the pipe by shape matching, the pressing contact area between the first rib 5 and the pipe and the pressing contact area between the second rib 6 and the pipe are greatly reduced, respectively, so that the tightness of the first rib 5 and the second rib 6 in fixing the pipe can be improved.

[0053] When installing the fastening device and the pipeline, the first clamp 1 and the second clamp 2 can be moved away from each other, so as to reserve enough installation space for the pipeline. Then the first clamp 1 and the second clamp 2 are installed along the radial direction of the pipeline, so that the first clamp 1 and the second clamp 2 surround the pipeline. And the first rib 5, or the second rib 6, or the first rib 5 and the second rib 6 cooperate to form a pressure contact with the pipeline. Finally, the other end of the first clamp 1 and the other end of the second clamp 2 are connected by the detachable connection component 4, so as to achieve the fastening of the pipeline. In some embodiments, a part of the detachable connection component 4 can be installed on the first clamp 1, and another part of the detachable connection component 4 can be installed on the second clamp 2.

[0054] In an optional embodiment of the utility model, the end surface of the first rib 5 away from the first clamp 1 is an arc-shaped surface.

[0055] In the embodiment of the utility model, the end face of the first rib 5 away from the first clamp 1 is an arcuate surface, which can be understood as a smooth transition of the end face of the first rib 5 for forming a pressure contact with the pipe, thereby preventing the first rib 5 from crushing the pipe when tightening the pipe.

[0056] In summary, the embodiment of the utility model further discloses a fastening device, which may include a first clamp 1, a second clamp 2, a rotating shaft 3 and a detachable connection component 4, wherein the first clamp 1 and the second clamp 2 cooperate to form an ellipse, wherein one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3, so that a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the detachable connection component 4 connects the other end of the first clamp 1 and the other end of the second clamp 2, so that the first clamp 1 and the second clamp 2 fasten the pipe. A first rib 5 is provided along the inner side of the first clamp 1. Alternatively, a second rib 6 is provided along the inner side of the second clamp 2. Alternatively, a first rib 5 is provided along the inner side of the first clamp 1, and a second rib 6 is provided along the inner side of the second clamp 2. Thus, the assembly and disassembly efficiency of the fastening device is improved through the cooperation of the split structure and the detachable connecting component 4. While facilitating the later maintenance of the pipeline, the fastening degree of the pipeline is further improved through the arrangement of the first rib 5 and / or the second rib 6.

[0057] In an optional embodiment of the utility model, when the first rib 5 and the second rib 6 are provided, the first rib 5 and the second rib 6 cooperate to form an ellipse.

[0058] In the embodiment of the utility model, the first rib 5 and the second rib 6 cooperate to form an ellipse, that is, the first rib 5 and the second rib 6 are on the same ellipse, so that when the first rib 5 and the second rib 6 respectively form pressure contact with the pipe, the pressure contact force between the first rib 5 and the pipe and the pressure contact force between the second rib 6 and the pipe can be ensured to be consistent, thereby improving the force uniformity of the pipe.

[0059] In some embodiments, when the connecting lines at both ends of the first clamp 1 coincide with the short axis of the ellipse, and the connecting lines at both ends of the second clamp 2 coincide with the corresponding short axis of the ellipse, the connecting lines at both ends of the first rib 5 coincide with the short axis corresponding to the ellipse formed by the first rib 5 and the second rib 6, and the connecting lines at both ends of the second rib 6 coincide with the short axis corresponding to the ellipse formed by the first rib 5 and the second rib 6; in other embodiments, when the connecting lines at both ends of the first clamp 1 coincide with the long axis of the ellipse, and the connecting lines at both ends of the second clamp 2 coincide with the corresponding long axis of the ellipse, the connecting lines at both ends of the first rib 5 coincide with the long axis corresponding to the ellipse formed by the first rib 5 and the second rib 6, and the connecting lines at both ends of the second rib 6 coincide with the long axis corresponding to the ellipse formed by the first rib 5 and the second rib 6.

[0060] In an optional embodiment of the utility model, the length of the minor axis of the ellipse formed by the cooperation of the first rib 5 and the second rib 6 is smaller than the outer diameter of the pipe. Also, the length of the major axis of the ellipse formed by the cooperation of the first rib 5 and the second rib 6 is larger than the outer diameter of the pipe.

[0061] In the embodiment of the utility model, when the short axis length corresponding to the ellipse formed by the cooperation of the first rib 5 and the second rib 6 is less than the outer diameter of the pipe, and the long axis length corresponding to the ellipse formed by the cooperation of the first rib 5 and the second rib 6 is greater than the outer diameter of the pipe, the corresponding short axis area will first press against the pipe, and because the short axis length is less than the outer diameter of the pipe, the first clamp 1 and the second clamp 2 will be pulled to deform, thereby shortening the long axis length. Thus, the first clamp 1 and the second clamp 2 form an interference fit with the pipe, which can prevent the fastening device and the pipe from sliding, and improve the connection tightness between the fastening device and the pipe. For example, the short axis length can be 0.1mm-0.5mm (including 0.1mm and 0.5mm) less than the outer diameter of the pipe. The long axis length can be 0.1mm-0.5mm (including 0.1mm and 0.5mm) greater than the outer diameter of the pipe. Those skilled in the art can determine the corresponding short axis length and long axis length according to the actual test results of the pipe to be fastened, and no excessive restrictions are made here.

[0062] Reference Figure 2 , Figure 3 as well as Figure 4As shown, the embodiment of the utility model further provides a fastening device, the device includes a first clamp 1, a second clamp 2, a rotating shaft 3 and a detachable connection component 4, the first clamp 1 and the second clamp 2 cooperate to form an ellipse, wherein one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3, so that a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the detachable connection component 4 connects the other end of the first clamp 1 and the other end of the second clamp 2, so that the first clamp 1 and the second clamp 2 fasten the pipe. The detachable connection component 4 may include a limit spring 41, a slider 42 and a limit buckle 43. The limit spring 41 is sleeved on the other end of the first clamp 1. The slider 42 is slidably connected to the other end of the first clamp 1 and is pressed against the limit spring 41. The limiting buckle 43 is arranged on the other end of the second clamp 2, wherein when the slider 42 presses the limiting spring 41 to retract, it moves into the limiting buckle 43, and cooperates with the limiting buckle 43 when the limiting spring 41 is reset to limit the slider 42.

[0063] In the embodiment of the utility model, the fastening device is mainly used to fasten pipes that need to be fixed in household appliances. For example, it can be used for drainage, pumping, exhaust, and air extraction, etc., which are not limited here. The fastening device may include a first clamp 1, a second clamp 2, a rotating shaft 3, and a detachable component. Among them, the two ends of the first clamp 1 are respectively matched with the two ends of the second clamp 2 to form a ring structure with an elliptical radial cross section to fix the pipe. The split fastening device can facilitate the assembly between the pipe and the fastening device, so that the fastening device does not need to be adjusted to an appropriate angle for the pipe to pass axially, thereby improving the assembly efficiency of the fastening device. Among them, one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3. That is to say, a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the corresponding installation opening angle is adjustable, so that it is easier to assemble the first clamp 1 and the second clamp 2 to the pipe.

[0064] During the assembly process of the pipeline and the fastening device, the first clamp 1 can be adjusted around the rotating axis 3; or, the second clamp 2 can be adjusted around the rotating axis 3; or, the first clamp 1 and the second clamp 2 can be adjusted around the rotating axis 3 at the same time, so as to achieve the assembly of the fastening device to the pipeline along the radial direction of the pipeline.

[0065] The detachable connection component 4 is mainly used to realize the detachable connection between the other end of the first clamp 1 and the other end of the second clamp 2. That is to say, the detachable connection component 4 is located between the first clamp 1 and the second clamp 2 to form a space for pipe installation, corresponding to the installation opening. Thus, the connection between the first clamp 1 and the second clamp 2 and the closure of the installation opening are realized through the detachable connection component 4, thereby realizing the fastening of the pipe and improving the convenience of disassembly and assembly of the fastening device, so as to facilitate the maintenance of the pipe later.

[0066] Furthermore, when the first clamp 1 and the second clamp 2 match in shape to form an ellipse, the short axis of the corresponding ellipse will form a pressure contact with the pipe in advance, thereby improving the fastening degree of the fastening device to the pipe.

[0067] In some embodiments, the cross-sectional shape of the first clamp 1 may be the arc length corresponding to half of an ellipse, and correspondingly, the cross-sectional shape of the second clamp 2 may be consistent with that of the first clamp 1. For example, the connecting lines at both ends of the first clamp 1 coincide with the major axis corresponding to the ellipse, the connecting lines at both ends of the second clamp 2 coincide with the major axis corresponding to the ellipse, and the connecting line between the center position of the first clamp 1 and the center position of the second clamp 2 coincides with the minor axis corresponding to the ellipse.

[0069] When installing the fastening device and the pipeline, the first clamp 1 and the second clamp 2 can be moved away from each other, so as to reserve enough installation space for the pipeline. Then the first clamp 1 and the second clamp 2 are installed along the radial direction of the pipeline, so that the first clamp 1 and the second clamp 2 surround the pipeline. Finally, the other end of the first clamp 1 and the other end of the second clamp 2 are connected by the detachable connection component 4, so as to achieve the fastening of the pipeline. In some embodiments, a part of the detachable connection component 4 can be installed on the first clamp 1, and another part of the detachable connection component 4 can be installed on the second clamp 2.

[0070] The detachable connection component 4 may include a limit spring 41, a slider 42 and a limit buckle 43. The limit spring 41 is sleeved on the other end of the first hoop 1, which can be understood as the limit spring 41 being movably connected to the first hoop 1. The limit spring 41 can slide freely along the first hoop 1 without being limited at both ends. The slider 42 is slidably connected to the other end of the first hoop 1 and is pressed against the limit spring 41. In other words, the slider 42 can be located between the other end of the first hoop 1 and the limit spring 41, so that the slider 42 can be pressed when the limit spring 41 is in the initial state. Among them, when the slider 42 is forced to compress the limit spring 41 upward, the limit spring 41 is converted from the initial state to the retracted state, and the slider 42 can slide in the inner direction away from the first hoop 1.

[0071] The limiting buckle 43 is arranged on the other end of the second clamp 2, wherein when the slider 42 presses the limiting spring 41 to retract, it moves into the limiting buckle 43, and when the pressure applied to the slider 42 is removed, the limiting spring 41 is reset (converted from the retracted state to the initial state), so that the slider 42 enters the limiting buckle 43, and the limiting spring 41 cooperates with the limiting buckle 43 to limit the slider 42.

[0072] When installing the fastening device and the pipeline, the first clamp 1 and the second clamp 2 can be moved away from each other, so as to reserve enough installation space for the pipeline. Then the first clamp 1 and the second clamp 2 are installed along the radial direction of the pipeline, so that the first clamp 1 and the second clamp 2 surround the pipeline. And the first rib 5 and the second rib 6 cooperate to form a pressure contact with the pipeline. Finally, by pressing the slider 42, when the slider 42 is forced to compress the limit spring 41 upward, the limit spring 41 is converted from the initial state to the retracted state, and the slider 42 can slide in the inner direction away from the first clamp 1, that is, the slider 42 moves close to the limit buckle 43. When the slider 42 presses the limit spring 41 to retract, it moves into the limit buckle 43, and when the pressure applied to the slider 42 is removed, the limit spring 41 is reset (converted from the retracted state to the initial state), so that the slider 42 enters the limit buckle 43, and the limit spring 41 cooperates with the limit buckle 43 to limit the slider 42. Thus, the other end of the first clamp 1 and the other end of the second clamp 2 are connected to achieve the fastening of the pipeline.

[0073] Furthermore, when the first clamp 1 and the second clamp 2 are rotatably connected and the slider 42 is limited by the limit spring 41 and the limit buckle 43, the pipes with different radii with a small radius difference can be fastened by adapting the retraction stroke of the limit spring 41, the depth of the limit buckle 43, the elasticity of the first clamp 1, and the elasticity of the second clamp 2. Thus, the product applicability of the fastening device can be further expanded.

[0074] When the pipeline is being repaired or in other scenarios where the fastening device needs to be removed from the pipeline, pressure can be applied to the slider 42 so that the slider 42 presses the limit spring 41 and retracts, thereby moving the slider 42 out of the limit buckle 43. At this time, the first clamp 1 can also be rotated along the rotation axis 3 so that the slider 42 is away from the limit buckle 43. When the pressure applied to the slider 42 is removed, the limit spring 41 is reset (converted from the retracted state to the initial state), and at this time, the other end of the first clamp 1 and the other end of the second clamp 2 are away from each other, and the first clamp 1 and the second clamp 2 are removed along the radial direction of the pipeline, and the removal of the fastening device is completed.

[0075] During the assembly or disassembly of the fastening device, no tools are required or other parts need to be disassembled, thereby avoiding the situation where the fastening device cannot be assembled or disassembled due to lack of tools or parts are lost during the assembly or disassembly process.

[0076] In an optional utility model embodiment, referring to Figure 1 and Figure 2 As shown, there are two limit buckles 43 , which are spaced apart to form a receiving channel for the limit spring 41 to be embedded therein, and the slider 42 is arranged to penetrate the two limit buckles 43 along the radial direction of the first hoop 1 .

[0077] In the embodiment of the utility model, there are two limit buckles 43, and the two limit buckles 43 are spaced apart, and the gap in the middle can form an accommodating channel for the limit spring 41 to be embedded, which can also be called an accommodating channel for the limit spring 41 and the slider 42 to be embedded, so that the slider 42 can move along the accommodating channel. When the slider 42 is fixed in the limit buckle 43, the two ends of the slider 42 can be fixed with the limit buckle 43 respectively, that is, the slider 42 passes through the two limit buckles 43 along the radial direction of the first clamp 1, thereby improving the connection stability of the slider 42 and further improving the tightness of the pipeline.

[0078] Reference Figure 1-4As shown, the embodiment of the utility model further provides a fastening device, the device includes a first clamp 1, a second clamp 2, a rotating shaft 3 and a detachable connection component 4, the first clamp 1 and the second clamp 2 cooperate to form an ellipse, wherein one end of the first clamp 1 and one end of the second clamp 2 are rotatably connected through the rotating shaft 3, so that a space for pipe installation is formed between the first clamp 1 and the second clamp 2, and the detachable connection component 4 connects the other end of the first clamp 1 and the other end of the second clamp 2, so that the first clamp 1 and the second clamp 2 fasten the pipe. The detachable connection component 4 may include a limit spring 41, a slider 42 and a limit buckle 43. The limit spring 41 is sleeved on the other end of the first clamp 1. The slider 42 is slidably connected to the other end of the first clamp 1 and is pressed against the limit spring 41. The limit buckle 43 is arranged on the other end of the second hoop 2, wherein when the slider 42 presses the limit spring 41 to retract, it moves into the limit buckle 43, and cooperates with the limit buckle 43 when the limit spring 41 is reset to limit the slider 42. In addition, the device further includes a connecting member 7 and a bending member 8, wherein the limit spring 41 is sleeved on the connecting member 7, the slider 42 is slidably connected to the connecting member 7, and the bending member 8 is installed at one end of the connecting member 7 away from the first hoop 1 to limit the end of the limit spring 41 away from the slider 42.

[0079] In the embodiment of the utility model, the difference from the content described in the above utility model embodiment is mainly that: the connecting member 7 is used to provide the installation of the slider 42 and the limit spring 41, wherein the connecting member 7 can be a plate-like structure extending in the tangential direction of the other end of the first clamp 1, or a rod-like structure extending in the tangential direction of the other end of the first clamp 1. Those skilled in the art can determine the specific shape of the connecting member 7 according to actual design requirements or actual processing technology, and no excessive restrictions are made here. Among them, the connecting member 7 and the first clamp 1 can be an integrated structure, so as to reduce the production cost of the first clamp 1 and improve the assembly efficiency.

[0080] In some embodiments, a sliding hole adapted to the shape of the connecting member 7 is provided in the middle area of ​​the slider 42, so that the slider 42 can slide on the connecting member 7 through the clearance fit between the sliding hole and the connecting member 7. The bending member 8 is located on an end face of the connecting member 7 away from the first hoop 1, and is arranged at an angle with the connecting member 7. For example, the angle between the bending member 8 and the connecting member 7 is an acute angle or a right angle. Thus, the bending member 8 can be used to limit the end of the limit spring 41 away from the first hoop 1 (which can also be understood as the end away from the slider 42). In some embodiments, the length of the connecting member 7 can be consistent with the length of the limit spring 41 when it is in the initial state.

[0081] In an optional embodiment of the utility model, the connecting member 7 and the bending member 8 are an integrated structure.

[0082] In the embodiment of the utility model, the connecting member 7 and the bending member 8 are an integrated structure, that is, the first hoop 1, the connecting member 7 and the bending member 8 are integrally formed. Therefore, on the one hand, the production cost of the fastening device can be reduced and the processing steps can be reduced. On the other hand, it can facilitate the assembly of the limit spring 41. During the assembly process of the limit spring 41, the limit spring 41 can be sleeved on the connecting member 7, and then the end of the connecting member 7 away from the first hoop 1 can be bent to form a bending member 8 that forms an end limit for the limit spring 41. In other words, the bending member 8 can be regarded as a part of the connecting member 7, so that the assembly efficiency of the fastening device can be improved.

[0083] In an optional embodiment of the utility model, the radial length of the connecting member 7 in the first clamp 1 is the same as the inner diameter of the limit spring 41 .

[0084] In the embodiment of the utility model, the radial length of the connecting member 7 in the first hoop 1 is the same as the inner diameter of the limit spring 41, that is, when the limit spring 41 is sleeved on the connecting member 7, it is clearance-matched with the connecting member 7, and the clearance is zero. Thus, the radial displacement of the limit spring 41 during the retraction process can be reduced, so as to extend the service life of the limit spring 41 and prevent the limit spring 41 from being twisted during repeated retraction and resetting.

[0085] In an optional embodiment of the utility model, the rotating shaft 3 includes a latch rotating shaft.

[0086] In the embodiment of the utility model, the rotating shaft 3 may include a latch rotating shaft, and when the latch rotating shaft is used, the assembly and disassembly between the first clamp 1 and the second clamp 2 can be facilitated, thereby further optimizing the product performance of the fastening device.

[0087] In some embodiments, the first hoop 1, the first rib 5, the connecting piece 7 and the bending piece 8 are all integrated structures, and the second hoop 2, the second rib 6 and the limit buckle 43 are all integrated structures. Therefore, during the assembly of the fastening device, the rotating shaft 3 is first inserted into the rotating connection between the first hoop 1 and the second hoop 2. Then the slider 42 is sleeved on the connecting piece 7, and then the limit spring 41 is sleeved on the connecting piece 7. Finally, a part of the connecting piece 7 is bent to limit the limit spring 41.

When the slider 42 presses the limit spring 41 to retract, it moves into the limit buckle 43, and when the pressure applied to the slider 42 is removed, the limit spring 41 is reset (converted from the retracted state to the initial state), so that the slider 42 enters the limit buckle 43, and the limit spring 41 cooperates with the limit buckle 43 to limit the slider 42.
