Description

Technical Field

[0001] The invention relates to the technical field of pipeline connectors, in particular to a detachable clamping hoop and a manufacturing method thereof. Background Art

[0002] After two pipes are butted together, a clamp is usually used to clamp the butt joint of the pipes, in order to achieve the connection of the pipes and to ensure that there is no leakage at the joint. However, the existing clamp is usually composed of two parts, which are respectively put on the pipes, and then a bolt is passed through one part and connected to the other part to complete the clamp. The bolt holes on the two parts need to be fully aligned when the bolt is inserted, otherwise it is difficult for the bolt to pass through. However, it is difficult to fully align the bolt holes of the two parts of the clamp when connected to the pipe, so users need to spend a lot of time to align the bolt holes. Summary of the invention

[0003] The purpose of the present invention is to provide a detachable clamping clamp to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a detachable clamp, comprising a first part and a second part; the outer wall surfaces of the first part and the second part are both provided with protrusions, and are sleeved on the protrusions of the first part and the second part through a fastener; the fastener comprises a support frame, the interior of the support frame is provided with a sleeve hole, and the top of the support frame is also provided with a threaded hole, and a bolt is provided through the threaded hole and then contacts the protrusion, so that the first part and the second part are tightly clamped on the pipe wall.

[0005] As a preferred technical solution of the present invention: the second part includes a shell, and a stop block is provided inside the shell.

[0006] As a preferred technical solution of the present invention: the number of the stop blocks is two and they are symmetrically distributed in the shell, and a fixing cavity is formed in the shell.

[0007] As a preferred technical solution of the present invention: a sealing ring is also provided in the fixed cavity.

[0008] As a preferred technical solution of the present invention: both sides of the shell are provided with fitting parts, and the fitting parts also have the protruding parts.

[0009] As a preferred technical solution of the present invention: the first part and the second part have the same structure, and the first part and the second part are made of stainless steel.

[0010] As a preferred technical solution of the present invention: the cross-section of the sleeve hole is rectangular; wherein the width of the sleeve hole is equal to the width of the protrusion, and the dimension of the sleeve hole in the height direction is greater than the sum of the thicknesses of the two protrusions.

[0011] The present invention also discloses a method for manufacturing a detachable clamp: S1: selecting an existing stainless steel plate and stamping the stainless steel plate to form a shell and a fitting portion; S2: selecting a circular ring with an outer diameter equal to the inner diameter of the shell and welding it inside the shell to form a stop block inside the shell; S4: then welding a square stainless steel plate to the edge of the shell to provide a protruding portion at the edge of the shell.

[0012] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. Since the device uses a fastener to be sleeved on the protruding parts of the two parts, and then tightens the bolts on the fastener, the protruding parts of the two parts can be caused to move toward each other, so as to clamp the two parts on the pipe wall, and in this process, only the bolts need to be tightened, which completely solves the problem of low assembly efficiency of the existing clamp due to the alignment of the holes;

[0013] 2. Since the fastener is sleeved on the protruding portion, the first part and the second part of the device do not need to be connected by bolts, which simplifies the assembly steps of the two parts; secondly, reduces the assembly time of the two parts; and thirdly, when disassembling, only the fastener needs to be disassembled or the fastener needs to be directly destroyed to achieve rapid disassembly of the two parts.

[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0022] See also Figure 1-6 An embodiment of the present invention is as follows: a detachable clamping clamp comprises a first part 1 and a second part 2; a protrusion 21 is provided on the outer wall surface of the first part 1 and the second part 2, and is sleeved on the protrusion 21 of the first part 1 and the second part 2 through a fastener 3; the fastener 3 comprises a support frame 30, a sleeve hole 32 is provided inside the support frame 30, and a threaded hole 31 is also provided on the top of the support frame 30, and a bolt 33 is provided through the threaded hole 31 and then contacts the protrusion 21, so that the first part 1 and the second part 2 are tightly clamped on the pipe wall.

[0023] In summary, since the device uses the fastener 3 to be sleeved on the protrusions 21 of the two parts, and then tightens the bolts 33 on the fastener 3, the protrusions 21 of the two parts can be caused to move toward each other, so as to clamp the two parts on the pipe wall. In this process, only the bolts 33 need to be tightened, which can completely solve the problem of low assembly efficiency of the existing clamp due to the alignment of the holes;

[0024] In particular, since the fastener 3 is sleeved on the protrusion 21, the first part 1 and the second part 2 of the device do not need to be connected using bolts, which simplifies the assembly steps of the two parts; secondly, reduces the assembly time of the two parts; and thirdly, when disassembling, only the fastener 3 needs to be disassembled or the fastener 3 needs to be directly destroyed to achieve rapid disassembly of the two parts.

[0025] Based on this, pipes and other components can be firmly connected to ensure the reliability and stability of the connection, and it is not easy to be damaged by external forces. Quick installation: usually a simple fastening method is used, the installation process is convenient and fast, saving time and labor costs. Easy disassembly: when maintenance or replacement of parts is required, the clamp can be easily removed without causing damage to the connected parts.

[0026] Further, the second part 2 includes a housing 20, and a stop block 23 is provided inside the housing 20. Since the stop block 23 is provided inside the housing 20, the stop block 23 can be used to sleeve on both sides of the pipeline to prevent the housing 20 from axially moving on the pipeline.

[0027] Furthermore, since there are two stop blocks 23, which are symmetrically distributed in the housing 20, and a fixed cavity 22 is formed in the housing 20, the two stop blocks 23 can be further used to prevent the housing 20 from moving on the central axis of the pipeline. At the same time, a sealing ring 4 is also provided in the fixed cavity 22, so the fixed cavity 22 can be used to further prevent the sealing ring 4 from axially moving and causing leakage at the pipeline connection.

[0028] On the basis of the above scheme, since the fitting parts 24 are provided on both sides of the shell 20, and the fitting parts 24 also have the protrusions 21, the fitting parts 24 are used to fit on the pipe wall to increase the contact area between the device and the pipeline. At the same time, when the fitting part 24 presses another sealing ring on the pipe wall, the sealing performance of the clamp can be further improved.

[0029] In addition, since the structures of the first part 1 and the second part 2 are consistent, the processing of the two parts is convenient to reduce the processing cost of the equipment. At the same time, the material of the first part 1 and the second part 2 is stainless steel, which can enhance the structural strength of the equipment while improving the corrosion resistance of the equipment.

[0030] In summary, the stainless steel material makes the clamp not easy to rust, and can be used for a long time in a humid and corrosive environment. It is suitable for various harsh working conditions and has high strength. It can firmly connect pipes and other components to ensure the reliability and stability of the connection and is not easily damaged by external forces.

[0031] Furthermore, since the cross-section of the sleeve hole 32 is rectangular, and the width of the sleeve hole 32 is equal to the width of the protrusion 21, the fastener 3 will not cause the two parts to shift during the fixing process. At the same time, the height dimension of the sleeve hole 32 is greater than the sum of the thicknesses of the two protrusions 21, so sufficient space can be reserved so that the sleeve hole 32 can be easily and conveniently put on the two protrusions 21.

[0032] To sum up, although the device has a simple structure, it can reliably seal the pipe joints and has the advantage of easy disassembly and assembly, while eliminating the step of hole alignment. It also solves the problem that the existing clamp bolts are difficult to remove due to rust after long-term use, and the outer wall of the clamp is easily damaged during the removal process.

[0033] In addition, the present invention also provides a method for making a detachable clamp: S1: select an existing stainless steel plate and stamp the stainless steel plate to form a shell and a fitting portion; S2: select a circular ring with an outer diameter and an inner diameter of the shell and weld it inside the shell to form a stop block inside the shell; S4: then weld a square stainless steel plate to the edge of the shell to make the edge of the shell have a protrusion.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
