Referring to fig. 1, 2 and 3, an embodiment of the present application provides an adjustable pipe clamp 10 including a plurality of clamping assemblies 100 and a fastener 130. Each clamping assembly 100 comprises a clamping section 110 and an installation section 120 which are distributed along a first preset direction a and are connected with each other, inner walls 111 of the clamping sections of the plurality of clamping assemblies 100 surround to form a pipe cavity 1111 for clamping a pipeline, inner walls 121 of the installation sections of the plurality of clamping assemblies 100 surround to form an installation part for installing the adjustable pipe clamp 10, and the first preset direction a is the same as the extension direction of the axial lead of the pipe cavity 1111; the outer wall 112 of each clamping section is provided with a protrusion 1121 or a plurality of protrusions 1121 distributed in a step shape in the first preset direction a; the fastening element 130 is movably disposed along the first predetermined direction a and abuts against the outer walls 112 of the plurality of clamping sections.

In this application, a plurality of centre gripping subassemblies 100 are mutually supported and are used for the centre gripping to the pipeline, and fastener 130 is used for pressing from both sides a plurality of centre gripping subassemblies 100 simultaneously tightly to make a plurality of centre gripping subassemblies 100 closely laminate together, thereby realize the fixed to the pipeline that is being held. The inner walls 111 of the clamping sections of the plurality of clamping assemblies 100 surround to form a cavity for clamping a pipeline, and the inner walls 121 of the installation sections of the plurality of clamping assemblies 100 surround to form a cavity for installing the adjustable pipe clamp 10; in addition, the outer wall 112 of each gripping section is provided with a protrusion 1121 or a plurality of protrusions 1121 distributed in a step shape along the first predetermined direction a, and the fastening member 130 is used for movably sleeving the outer walls 112 of the plurality of clamping sections along the first predetermined direction a, this arrangement allows the inner diameter of the lumen 1111 to be adjusted and then held in a locked position against the outer wall 112 of the grasping section by the fastener 130 by moving the fastener 130 in the first predetermined direction a to the proper position, thereby realizing the clamping and fixing of the pipelines with different pipe diameters by one pipe clamp (equivalent to providing a universal pipe clamp), reducing the use cost of the pipe clamp compared with the mode of clamping the pipelines with different pipe diameters by using various pipe clamps, and the problem that the pipe clamps are easy to mix in the using process due to excessive types of the pipe clamps can be effectively avoided.

Each protrusion 1121 can be used for adjusting the size of the tube cavity 1111 in one level, when the outer wall 112 of each clamping section is provided with the plurality of protrusions 1121 which are distributed in a step shape in the first preset direction a, compared with a mode of only arranging one protrusion 1121, the size and specification of the tube cavity 1111 are adjusted in more levels, and the arrangement can further enhance the adjustability of the tube diameter of the tube cavity 1111, so that the adjustable tube clamp has high pipeline compatibility rate.

It should be noted that, since the pipe can be successfully clamped by the clamping assembly 100 to see whether the outer diameter of the pipe and the inner diameter of the pipe cavity 1111 match, the pipe diameter of the pipe herein refers to the outer diameter of the pipe.

To facilitate understanding of the technical solution, the working principle of the fastener 130 is explained here: when the adjustable pipe clamp 10 is used, the position of the fastening member 130 in the first preset direction a is adjusted according to the pipe diameter of the fixed pipe, and the pipe can be clamped and fixed by adjusting the position of the fastening member 130.

It should be noted that the specific number of clamping assemblies 100 is not limited, and may be 2, 3, 4, 5 or 6.

As an example, the clamping assembly 100 is provided with three.

In this embodiment, three clamping assemblies 100 are provided, so that compared with a form in which only two clamping assemblies are provided, the arrangement makes the formed tube cavity 1111 have higher flexibility, and is more easily matched with pipes with different tube diameters, thereby facilitating clamping of pipes with different tube diameters; compared with more than three forms, the adjustable pipe clamp is simpler in structure and more convenient to use.

It should be noted that, when the outer wall 112 of each of the clamping sections is provided with the plurality of protrusions 1121 which are distributed in the step shape in the first preset direction a, the distribution rule of the plurality of protrusions 1121 is not specifically limited, that is, the distance between the outer wall of the plurality of protrusions 1121 and the axial line of the tube cavity 1111 may be changed regularly, that is, from small to large, or from large to small; or irregularly, namely from small to large and then from large to small, or from large to small and then from small to large.

As an example, in the first preset direction a, the outer wall 112 of each grasping section is provided with a plurality of protrusions 1121 which are distributed in a step shape in the first preset direction a, and the distance from the outer wall of the protrusion 1121 to the axial line of the lumen 1111 gradually increases from one end far away from the mounting section 120 to one end close to the mounting section 120 of each grasping section 110.

In this embodiment, each clamping section 110 has a gradually increasing distance from the end far away from the mounting section 120 to the end near the mounting section 120 from the outer wall of the protrusion 1121 to the axis of the tube cavity 1111 (i.e., the distance varies regularly and is distributed from small to large), and this arrangement enables the overall structure of the adjustable tube clamp to have a better consistency (i.e., after the plurality of clamping assemblies 100 clamp the tube, the overall structure of the adjustable tube clamp is a structure in which the outer dimensions of each section of cylinder from one end to the other end gradually increase), thereby facilitating the process preparation, and this arrangement also enables the adjustable tube clamp to have a higher structural stability.

It should be noted that the extending angle of the side wall between any two adjacent protrusions 1121 is not particularly limited, and may be 90 ° (i.e., vertical), an obtuse angle, or an acute angle.

As an example, the side walls between any two adjacent protrusions 1121 extend at an angle of 90 ° (i.e., perpendicular to each other).

It should be noted that the shape of the inner wall 111 of the clamping section is not particularly limited as long as the inner wall 111 of the clamping section can contact with the outer wall of the pipe to achieve clamping.

As an example, the inner walls 111 of the plurality of gripping sections are all arcuate.

In this embodiment, all set up the inner wall 111 of getting the section with a plurality of clamps into the arc, this setting makes the outer wall that gets the inner wall 111 of getting the section and pipeline can laminate better to be convenient for carry out mild and stable centre gripping to the pipeline.

It should be noted that the shape of the outer wall 112 of the gripping section is not particularly limited as long as the fastening member 130 can be movably sleeved and supported on the outer walls 112 of the gripping sections in the first predetermined direction a.

As an example, the outer walls 112 of the plurality of gripping sections are each arcuate.

In this embodiment, the outer walls 112 of the plurality of clamping sections are all set to be arc-shaped, and the shapes of the outer walls 112 and the inner walls of the clamping sections are close to each other due to the setting, so that compared with the case that the difference between the shapes of the outer walls 112 and the shapes of the inner walls of the clamping sections is large, the difficulty of process preparation can be reduced, and the process preparation is facilitated.

As an example, when the plurality of grasping sections 110 abut against each other, the cross section of the lumen 1111 surrounded by the inner walls 111 of the plurality of grasping sections is circular.

In this embodiment, when a plurality of clamps 110 abut against each other, the cross section of the inner wall 111 of the plurality of clamps encircled the lumen 1111 that is formed is circular, and the lumen 1111 that is equivalent to be formed is a complete circle, and this setting enables the adjustable pipe clamp when the minimum pipe diameter of the clamp pipe is measured, the whole outer wall of the pipe in the pipe circumference direction all closely laminates with the inner wall 111 of the clamp section, thereby increasing the stability of the pipe when being clamped.

It should be noted that when the plurality of gripping sections 110 abut against each other, the diameter of the tube cavity 1111 is represented by the minimum diameter of the tube that the adjustable tube clamp can grip.

It should be noted that when the plurality of grasping sections 110 abut against each other, the diameter of the lumen 1111 is not particularly limited, and may be adjusted according to actual needs.

As an example, when the plurality of grasping sections 110 abut against each other, the diameter of the lumen 1111 is 6-15 mm, such as but not limited to 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm and 15mm in diameter or any range of values therebetween.

In this embodiment, when the plurality of gripping sections 110 abut against each other, the diameter of the tube cavity 1111 is limited to be within a range of 6-15 mm because the minimum tube diameter of several gas tubes commonly used in a special gas cabinet is within this range, and this arrangement enables the adjustable tube clamp to have a higher tube compatibility rate.

As an example, in the circumferential direction of the tube cavity 1111, both ends of the inner wall 111 of each grasping section are in circular arc transition.

In this embodiment, in the circumferential direction of the tube cavity 1111, both ends of the inner wall 111 of each clamping section are set to be in the form of arc transition, and this setting can avoid the damage to the pipeline caused by both ends of the inner wall 111 of the clamping section.

It should be noted that, in the first predetermined direction a, the distance difference between the outer walls of any two adjacent protrusions 1121 and the axial line of the lumen 1111 is not particularly limited.

As an example, in the first preset direction a, a difference between distances from the outer walls of any two adjacent protrusions 1121 to the axis of the tube cavity 1111, and a difference between a distance from the outer wall of one end of each clamping section 110 away from the mounting section 120 to the axis of the tube cavity 1111 and a distance from the outer wall of the adjacent protrusion 1121 to the axis of the tube cavity 1111 are 2 to 5mm, for example, but not limited to, the difference is any one of 2mm, 3mm, 4mm and 5mm or a value in a range between any two.

In the embodiment, each adjusting grade of the size of the tube cavity 1111 is limited within the range of 2-5 mm, and the tube diameter change of the formed tube cavity 1111 is similar to the tube diameter change rules of different types of tubes, so that the tube compatibility of the adjustable tube clamp can be further improved.

It should be noted that the specific form of the fastener 130 is not limited.

As an example, the fastening member 130 is in threaded connection with the outer wall 112 of the plurality of clamping sections, that is, the outer wall 112 of the clamping section is provided with a thread, the fastening member 130 is provided as a nut ring, and the plurality of clamping sections 110 are fixed by the cooperation of the thread and the nut ring, so as to fix the pipeline.

In this embodiment, the fastening member 130 and the outer walls 112 of the plurality of clamping sections are both in threaded connection, because the threaded connection can achieve a good fixing effect, and the fastening member 130 can be conveniently detached in the threaded connection, so that the pipeline can be conveniently fixed.

In other possible embodiments, the fastening member 130 may be an elastic member, such as a rubber ring, and the outer wall 112 of the clamping section is directly covered with the rubber ring, so as to fix the pipeline.

It should be noted that, in the first preset direction a, the size of the gripping section 110 is not particularly limited.

As an example, in the first preset direction a, each of the gripping sections 110 has a size of 35 to 50mm, for example, but not limited to, a value of any one of 35mm, 40mm, 45mm and 50mm or a value in a range between any two.

In this embodiment, the size of each clamping section 110 is limited within the range of 35-50 mm in the first preset direction a, and this arrangement enables the outer wall of the clamped pipe to have a sufficient contact area with the inner wall of the clamping section in this direction, so that the stability of clamping and fixing the pipe by the clamping assembly 100 can be further enhanced.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
