When the support adjustment member is driven to rotate by an external force, the clamp assembly and the base assembly can move along the length direction of the support adjustment member in opposite directions, that is, they can move away from or move closer to the support adjustment member simultaneously along the length direction of the support adjustment member, realizing the adjustment of the distance between the clamp assembly and the base assembly. This can adapt to different types of pipe installations or different installation environments, significantly improving the efficiency of pipe position adjustment and the adaptability of the adjustable clamp. The adjustable clamp of this solution consists of a clamp assembly, a base assembly, a support adjustment member, and a limiting assembly. The structure is relatively simple, with fewer parts, reducing production costs and facilitating manufacturing and maintenance. By setting a first limiting member on at least one of the support adjustment member and the clamp connecting rod, and a second limiting member on at least one of the support adjustment member and the base connecting rod, the minimum distance between the base plate and the clamp is limited. When the pipeline is subjected to external impact, the first and second limiting components can prevent the distance between the clamp assembly and the base assembly from decreasing, thereby avoiding deformation or displacement of the pipeline due to changes in distance.

[0034] See Figure 1 As shown, according to an embodiment of this application, an adjustable clamp is provided, including a clamp assembly 10, a base assembly 20, a support adjustment member 30, and a limiting assembly 40. The clamp assembly 10 includes a clamp 11 and a clamp connecting rod 12 fixedly connected to the clamp 11. The base assembly 20 includes a base plate 21 and a base connecting rod 22 fixedly connected to the base plate 21. The support adjustment member 30 has a first end and a second end disposed opposite to each other. The first end is provided with a first threaded connection portion 31, and the second end is provided with a second threaded connection portion 32. The thread directions of the first threaded connection portion 31 and the second threaded connection portion 32 are opposite. The support adjustment member 30 is connected to the clamp connecting rod 11 via the first threaded connection portion 31. The end threaded connection of 2, the support adjustment member 30 is threadedly connected to the end of the base connecting rod 22 through the second threaded connection part 32; the limiting component 40 includes a first limiting member 41 and a second limiting member 42, the first limiting member 41 is disposed on at least one of the support adjustment member 30 and the clamp connecting rod 12 to limit the minimum distance between the base plate 21 and the clamp 11, and the second limiting member 42 is disposed on at least one of the support adjustment member 30 and the base connecting rod 22 to limit the minimum distance between the base plate 21 and the clamp 11.

[0035] In this embodiment, the pipe can be fixed to the adjustable clamp by the clamp 11 of the clamp assembly 10, and the base plate 21 of the base assembly 20 can be fixedly connected to the mounting surface of the predetermined structure, so that the adjustable clamp fixes the pipe to the predetermined structure. The base plate 21 is provided with mounting holes, and the base plate is fixed to the mounting surface by connecting components such as bolts and screws passing through the mounting holes. The clamp connecting rod 12 of the clamp assembly 10 is threadedly connected to the first threaded connection part 31 of the first end of the support adjustment member 30, which can control the helical rotation between the clamp assembly 10 and the support adjustment member 30 so that the clamp assembly 10 moves along the length direction of the support adjustment member 30. The base connecting rod 22 of the base assembly 20 is threadedly connected to the second threaded connection part 32 of the second end of the support adjustment member 30, which can control the helical rotation between the base assembly 20 and the support adjustment member 30 so that the base assembly 20 moves along the length direction of the support adjustment member 30. That is, the clamp assembly 10 and the base assembly 20 are respectively threadedly connected to the two ends of the support adjustment member 30, and due to the first threaded connection at both ends of the support adjustment member 30... The threads of part 31 and the second threaded connection part 32 are opposite in direction. When the support adjustment member 30 is rotated by external force, the clamp assembly 10 and the base assembly 20 can move along the length direction of the support adjustment member 30, and the movement directions of the clamp assembly 10 and the base assembly 20 are opposite. That is, the clamp assembly 10 and the base assembly 20 can move away from or move closer to the support adjustment member 30 simultaneously along the length direction of the support adjustment member 30, thereby adjusting the distance between the clamp assembly 10 and the base assembly 20. This allows for adjustment of the relative position of the pipe and the mounting surface. When the pipe specifications or installation environment are different, the distance between the pipe and the mounting surface can be flexibly adjusted according to the pipe specifications or installation environment, expanding the application range of the adjustable clamp. Since the clamp assembly 10 and the base assembly 20 at both ends of the support adjustment member 30 can be adjusted synchronously in opposite directions, the adjustment efficiency of the adjustable clamp for the pipe position is significantly improved. By providing a first limiting member 41 on at least one of the support adjusting member 30 and the clamp connecting rod 12 to limit the minimum distance between the base plate 21 and the clamp 11, and by providing a second limiting member 42 on at least one of the support adjusting member 30 and the base connecting rod 22 to limit the minimum distance between the base plate 21 and the clamp 11, the distance between the clamp assembly 10 and the base assembly 20 will not decrease when the pipeline is subjected to external impact, thus preventing pipeline deformation. Furthermore, the first limiting member 41 and the second limiting member 42 can also be used for positioning during pipeline installation. By rotating the first limiting member 41 and the second limiting member 42 to predetermined positions in advance, the distance between the clamp assembly 10 and the base assembly 20 can be precisely adjusted via the support adjusting member 30, ensuring that the pipeline maintains a reasonable distance from the installation surface when installed in the predetermined position. The adjustable clamp of this embodiment has a simple overall structure with fewer components, reducing production costs, facilitating manufacturing and maintenance, and making adjustment easier.

[0036] In one embodiment of this application, the first threaded connection part 31 is provided with a first internal threaded hole, and the end of the clamp connecting rod 12 away from the clamp 11 is provided with a first external thread. The support adjustment member 30 and the clamp connecting rod are threadedly connected through the first external thread and the first internal threaded hole. The second threaded connection part 32 is provided with a second internal threaded hole, and the end of the base connecting rod 22 away from the base plate 21 is provided with a second external thread. The support adjustment member 30 and the base connecting rod 22 are threadedly connected through the second external thread and the second internal threaded hole. The first limiting member 41 includes a first limiting nut, which is threadedly connected to the clamp connecting rod 12. And / or, the second limiting member 42 includes a second limiting nut, which is threadedly connected to the base connecting rod 22.

[0037] In the above embodiments, since the first threaded connection part 31 is provided with a first threaded hole and the second threaded connection part is provided with a second threaded hole, and the thread directions of the first threaded connection part 31 and the second threaded connection part 32 are opposite, the support adjustment member can be set as a positive and negative thread nut. The positive and negative thread nut is threaded to the first external thread of the clamp connecting rod through its first threaded hole, and to the second external thread of the base connecting rod through its second threaded hole. This allows adjustment of the distance between the clamp assembly 10 and the base assembly 20, thereby adjusting the pipe position and improving the adaptability and usability of the adjustable clamp. By setting the first limiting member 41 as a first limiting nut that can be threadedly connected to the clamp connecting rod 12, and setting the second limiting member 42 as a second limiting nut that can be threadedly connected to the base connecting rod 22, the minimum distance between the clamp assembly 10 and the base assembly 20 can be limited, preventing the pipe position from shifting or deforming when the pipe is fixed to the predetermined structure by the adjustable clamp.

[0038] In another embodiment of this application, the first threaded connection part 31 is provided with a third external thread, and the end of the clamp connecting rod 12 away from the clamp 11 is provided with a third internal thread hole. The support adjusting member 30 and the clamp connecting rod 12 are threadedly connected through the third external thread and the third internal thread hole. The second threaded connection part 32 is provided with a fourth external thread, and the end of the base connecting rod 22 away from the base plate 21 is provided with a fourth internal thread hole. The support adjusting member 30 and the base connecting rod 22 are threadedly connected through the fourth external thread and the fourth internal thread hole. The first limiting member 41 includes a third limiting nut, and the third limiting nut is threadedly connected to the support adjusting member 30. And / or, the second limiting member 42 includes a fourth limiting nut, and the fourth limiting nut is threadedly connected to the support adjusting member 30.

[0039] In the above embodiment, since the first threaded connection part 31 is provided with a third external thread and the second threaded connection part 32 is provided with a fourth external thread, the support adjustment member 30 can be set as a stud with both positive and negative threads. The third external thread of the stud is threaded to the third internal thread hole of the clamp connecting rod 12, and the fourth external thread of the stud is threaded to the fourth internal thread hole of the base connecting rod 22. This allows adjustment of the distance between the clamp assembly 10 and the base assembly 20, thereby adjusting the relative position between the pipe and the mounting surface. This adapts to different types of pipes or different installation environments, improving the adaptability and applicability of the adjustable clamp in this embodiment. Because the external thread structure is on the support adjustment member 30, the third limiting nut of the first limiting member 41 and the fourth limiting nut of the second limiting member 42 are both threaded to the support adjustment member 30. The third limiting nut is close to the clamp connecting rod 12, and the fourth limiting nut is close to the base connecting rod 22, facilitating the limiting of the clamp connecting rod 12 and the base connecting rod 22.

[0040] In another embodiment of this application, the first threaded connection part 31 is provided with a fifth external thread, and the end of the clamp connecting rod 12 away from the clamp 11 is provided with a fifth internal thread hole. The support adjustment member 30 and the clamp connecting rod 12 are threadedly connected through the fifth external thread and the fifth internal thread hole. The second threaded connection part 32 is provided with a sixth internal thread hole, and the end of the base connecting rod 22 away from the base plate 21 is provided with a sixth external thread. The support adjustment member 30 and the base connecting rod 22 are threadedly connected through the sixth external thread and the sixth internal thread hole. The first limiting member 41 includes a fifth limiting nut, which is threadedly connected to the support adjustment member 30. And / or, the second limiting member 42 includes a sixth limiting nut, which is threadedly connected to the base connecting rod 22.

[0041] In the above embodiment, since the first threaded connection part 31 is provided with a fifth external thread and the second threaded connection part 32 is provided with a sixth internal thread hole, the end of the support adjustment member 30 near the clamp assembly 10 adopts a stud structure, and the end of the support adjustment member 30 near the base assembly 20 adopts a nut structure. The fifth external thread of the stud structure is connected to the fifth internal thread hole of the clamp connecting rod 12, and the sixth internal thread hole of the nut structure is connected to the sixth external thread of the base connecting rod 22. The distance between the clamp assembly 10 and the base assembly 20 can be adjusted by rotating the support adjustment member 30, which has both internal and external thread structures. That is, the relative position between the pipe and the mounting surface is adjusted to adapt to different types of pipes or different installation environments, thereby improving the adaptability of the adjustable clamp in this embodiment. Since the external thread structure is set on the first threaded connection part 31 of the support adjustment part 30 and the base connecting rod 22, the fifth limiting nut of the first limiting part 41 is threadedly connected to the first threaded connection part 31 to limit the clamp assembly 10, and the sixth limiting nut of the second limiting part 42 is threadedly connected to the base connecting rod 22 to limit the base assembly 20. This can prevent the pipe from deforming or leaking due to the reduced distance between the pipe and the mounting surface when the pipe is subjected to external force impact, thus improving the safety of the pipe.

[0042] In another embodiment of this application, the first threaded connection part 31 is provided with a seventh internal thread hole, and the end of the clamp connecting rod 12 away from the clamp 11 is provided with a seventh external thread. The support adjustment member 30 and the clamp connecting rod 12 are threadedly connected through the seventh external thread and the seventh internal thread hole. The second threaded connection part is provided with an eighth external thread hole, and the end of the base connecting rod 22 away from the base plate 21 is provided with an eighth internal thread hole. The support adjustment member 30 and the base connecting rod 22 are threadedly connected through the eighth external thread and the eighth internal thread hole. The first limiting member 41 includes a seventh limiting nut, which is threadedly connected to the clamp connecting rod 12. And / or, the second limiting member 42 includes an eighth limiting nut, which is threadedly connected to the support adjustment member 30.

[0043] In the above embodiment, since the first threaded connection part 31 is provided with a seventh internal threaded hole and the second threaded connection part 32 is provided with an eighth external threaded hole, the end of the support adjustment member 30 near the clamp assembly 10 adopts a nut structure, and the end of the support adjustment member 30 near the base assembly 20 adopts a stud structure. The seventh internal threaded hole of the nut structure is connected to the seventh external thread of the clamp connecting rod 12, and the eighth external thread of the stud structure is connected to the eighth internal threaded hole of the base connecting rod 22. The distance between the clamp assembly 10 and the base assembly 20 can be adjusted by rotating the support adjustment member 30, which has both internal and external thread structures. That is, the relative position between the pipe and the mounting surface is adjusted to adapt to different types of pipes or different installation environments, thereby improving the adaptability of the adjustable clamp in this embodiment. Since the external thread structure is set on the second threaded connection part 32 of the support adjustment member 30 and the clamp connecting rod 12, the seventh limiting nut of the first limiting member 41 is threadedly connected to the clamp connecting rod 12 to limit the clamp assembly 10, and the eighth limiting nut of the second limiting member 42 is threadedly connected to the support adjustment member 30 to limit the base assembly 20. This can prevent the pipe from deforming or leaking due to the reduced distance between the pipe and the mounting surface when the pipe is subjected to external force impact, thus improving the safety of the pipe.

[0044] Furthermore, the adjustable clamp also includes a clamp fixing member 50. The clamp 11 comprises two semi-circular clamps 111, which are detachably connected via the clamp fixing member 50. Further, one of the two semi-circular clamps 111 is fixedly connected to the clamp connecting rod 12. The clamp 11, consisting of two semi-circular clamps 111 detachably connected via the clamp fixing member 50, allows the two semi-circular clamps 111 to be placed on either side of the pipe during installation, and then connected together via the clamp fixing member 50, thus conveniently securing the pipe within the clamp 11. When pipe maintenance, replacement, or adjustment is required, the clamp fixing member 50 can be easily removed to separate the two semi-circular clamps 111 for easy operation.

[0045] Furthermore, the clamp fastener 50 includes a bolt assembly, a screw, or a snap-fit ​​assembly.

[0046] Furthermore, the support adjustment member 30 is provided with an adjustment operation part, which is located between the first threaded connection part 31 and the second threaded connection part 32. The adjustment operation part includes a hexagonal nut or handle, etc., and the position of the pipe can be adjusted by rotating the support adjustment member 30 through tools or manual operation, which improves the operability of the adjustable clamp.

[0047] Furthermore, the base plate and the base connecting rod 22 can be integrated or separate; and / or, the clamp and the clamp connecting rod 12 can be integrated or separate. An integrated design improves structural strength, while a separate design increases flexibility and facilitates disassembly and installation.

[0048] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0049] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
