Description

Technical Field

[0001] This application relates to the field of tubular workpiece assembly technology, and more specifically, to a pipe clamp. Background Technology

[0002] Some tubular workpieces need to be installed on joints. In related technologies, tubular workpieces are usually disassembled and assembled directly by hand. However, some disassembly and assembly points are difficult to do by hand, which can easily cause the tubular workpiece to be excessively twisted or stretched, resulting in leakage or wear of the joint or tubular workpiece. Utility Model Content

[0003] In view of this, this application provides a pipe clamp that can assist in the assembly and disassembly of tubular workpieces.

[0004] One embodiment of this application provides a pipe clamp. The pipe clamp is capable of clamping tubular workpieces. The pipe clamp includes a clamp body and a pivot. The clamp body has two clamps pivotally connected to the pivot. The pipe clamp also includes two extension chucks. One clamp body is connected to one extension chuck. The extension chuck includes an extension arm and a clamping head. One end of the extension arm of the extension chuck is connected to the clamp body. The other end of the extension arm is connected to the clamping head. The extension arm extends radially along the pivoting direction of the clamp body. When the two clamp bodies rotate relative to each other, the two clamping heads can come closer together to clamp the tubular workpiece.

[0005] Pipe clamps, by incorporating an extension arm, extend the position of the clamping head relative to the hand, allowing the clamping head to be moved to different disassembly and assembly positions, facilitating the disassembly and assembly of tubular workpieces. Furthermore, the fixed clamping of the two clamping heads reduces vibration and wear on the tubular workpiece. Therefore, pipe clamps can assist in the disassembly and assembly of tubular workpieces, improving efficiency and safety.

[0006] In some embodiments of this application, the extension arm is detachably connected to the clamp body.

[0007] Pipe clamps can be fitted with extension arms of different lengths to accommodate different installation positions of tubular workpieces. They can also be fitted with clamping heads of different sizes to accommodate tubular workpieces of different thicknesses, thereby improving the convenience of using pipe clamps to assisted in the assembly and disassembly of tubular workpieces.

[0008] In some embodiments of this application, the extension chuck further includes an adapter. The adapter is fixedly mounted on the chuck body. The extension arm and the adapter are detachably connected.

[0009] By adding an adapter to the clamp body, the detachable structure that is compatible with the extension arm does not need to be directly installed on the clamp body, which helps to reduce the difficulty of setting up the detachable structure and facilitates the disassembly and assembly of the extension arm.

[0010] In some embodiments of this application, the extension arm and the adapter are threaded together.

[0011] The extension arm is assembled and disassembled via a threaded connection. The process of assembling and disassembling the extension arm is simple and can improve the stability of the extension arm when it is fixed to the clamp body.

[0012] In some embodiments of this application, the extension arm and the adapter are connected by an interference fit.

[0013] The extension arm and adapter can be stably connected through an interference fit, and the plug-and-play design of the extension arm and adapter makes them easy to assemble and disassemble.

[0014] In some embodiments of this application, the clamp body includes a gripping section, a pivoting section, and a clamping section. The gripping section, pivoting section, and clamping section are connected sequentially. The pivoting section is pivotally connected to a pivot. An adapter is fixedly disposed on the clamping section.

[0015] The extension arm can be assembled far away from the gripping section, which on the one hand makes it easier to delay the position of the extension chuck in clamping the tubular workpiece, and on the other hand helps to avoid the extension chuck affecting the hand's grip on the clamp body.

[0016] In some embodiments of this application, the end of the clamping section away from the pivot section is provided with a mounting plane. The adapter is fixedly disposed on the mounting plane.

[0017] Setting an assembly plane facilitates the fixed connection of the adapter and improves the stability of the adapter.

[0018] In some embodiments of this application, the extension arm and the clamp body are threaded together.

[0019] The extension arm is assembled and disassembled via a threaded connection. The process of assembling and disassembling the extension arm is simple and can improve the stability of the extension arm when it is fixed to the clamp body.

[0020] In some embodiments of this application, the extension arm and the clamp body are connected by an interference fit.

[0021] The extension arm and clamp body are stably connected by an interference fit, and the direct plug-in and plug-out design of the extension arm and clamp body facilitates assembly and disassembly.

[0022] In some embodiments of this application, the clamping head has a clamping surface. The clamping surface is an arc surface. The clamping surfaces of the two clamping heads are arranged facing each other. When the two clamping bodies rotate relative to each other, the two clamping surfaces can come closer together to clamp the tubular workpiece.

[0023] The curved clamping surface is easier to fit the clamping surface of the tubular workpiece, improving the stability of the fixed clamping of the tubular workpiece.

[0024] In some embodiments of this application, the axis of the clamping surface is parallel to the axis of the pivot.

[0025] The force applied by the hand to the clamp body is roughly the same as the force applied by the clamping surface to the tubular workpiece. This helps to avoid generating rotational torque on the tubular workpiece, thus enabling stable clamping of the tubular workpiece.

[0026] In some embodiments of this application, the side of the clamping surface furthest from the pivot is defined as the far side. The side of the clamping surface closest to the pivot is defined as the near side. The distance between the far sides of the two clamping surfaces is less than the distance between the near sides of the two clamping surfaces.

[0027] The above structure enables the two clamping heads to form a wedge-shaped structure when clamping the tubular workpiece. When a force is applied to clamp the tubular workpiece, the tubular workpiece can be pushed to the far side, producing a tightening effect, which helps to prevent the tubular workpiece from slipping during clamping.

[0038] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0040] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0041] Some tubular workpieces need to be installed on joints. In related technologies, tubular workpieces are usually disassembled and assembled directly by hand. However, some disassembly and assembly points are difficult to do by hand, which can easily cause the tubular workpiece to be excessively twisted or stretched, resulting in leakage or wear of the joint or tubular workpiece.

[0042] Embodiments of this application provide a pipe clamp. The pipe clamp is capable of clamping tubular workpieces. The pipe clamp includes a clamp body and a pivot. The clamp body has two parts and is pivotally connected to the pivot. The pipe clamp also includes two extension chucks. One extension chuck is connected to one clamp body. Each extension chuck includes an extension arm and a clamping head. One end of the extension arm of the extension chuck is connected to the clamp body. The other end of the extension arm is connected to the clamping head. The extension arm extends radially along the pivoting direction of the clamp body. When the two clamp bodies rotate relative to each other, the two clamping heads can come closer together to clamp the tubular workpiece.

[0043] Pipe clamps, by incorporating an extension arm, extend the position of the clamping head relative to the hand, allowing the clamping head to be moved to different disassembly and assembly positions, facilitating the disassembly and assembly of tubular workpieces. Furthermore, the fixed clamping of the two clamping heads reduces vibration and wear on the tubular workpiece. Therefore, pipe clamps can assist in the disassembly and assembly of tubular workpieces, improving efficiency and safety.

[0044] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] See Figure 1 One embodiment of this application provides a pipe clamp 100. The pipe clamp 100 is capable of clamping tubular workpieces (not shown). The pipe clamp 100 includes a clamp body 10 and a pivot 20. The clamp body 10 has two parts and is pivotally connected to the pivot 20. The clamp body 10 is held by a user's hand, and by holding the clamp body 10 and applying force, the two parts can be rotated to clamp the tubular workpiece.

[0046] In some embodiments, the clamp body 10 includes a gripping section 11, a pivoting section 12, and a clamping section 13. The gripping section 11 is for the user's hand to hold. The pivoting section 12 is pivotally connected to a pivot 20. Both the gripping section 11 and the clamping section 13 are connected to the pivoting section 12. By gripping the gripping section 11, the clamping section 13 is rotated, thereby clamping the tubular workpiece.

[0047] In some embodiments, the pipe clamp 100 further includes two extension chucks 30. One clamp body 10 is connected to one extension chuck 30. Each extension chuck 30 includes an extension arm 31 and a clamping head 32. One end of the extension arm 31 of the extension chuck 30 is connected to the clamp body 10. The other end of the extension arm 31 is connected to the clamping head 32. The extension arm 31 extends radially along the clamp body 10 for pivoting. When the two clamp bodies 10 rotate relative to each other, the two clamping heads 32 can come closer together to clamp the tubular workpiece.

[0048] The pipe clamp 100 extends the position of the clamping head 32 relative to the hand by providing an extension arm 31, allowing the clamping head 32 to move to different disassembly and assembly positions, facilitating the disassembly and assembly of tubular workpieces. Furthermore, the fixed clamping of the two clamping heads 32 reduces vibration and wear on the tubular workpiece. Therefore, the pipe clamp 100 assists in the disassembly and assembly of tubular workpieces, improving efficiency and safety.

[0049] See Figure 2 It is understood that in some embodiments, the extension arm 31 may have an angle greater than zero between its extension direction and the radial direction of the pivot of the clamp 10, and the extension arm may extend approximately in the radial direction of the pivot of the clamp 10.

[0050] See Figure 2 and Figure 3 In some embodiments, the extension arm 31 is detachably connected to the clamp body 10. The pipe clamp 100 can be fitted with extension arms 31 of different lengths to adapt to different installation positions of tubular workpieces, and the pipe clamp 100 can also be fitted with clamping heads 32 of different sizes to adapt to tubular workpieces of different thicknesses, thereby improving the convenience of the pipe clamp 100 in assisting in the installation and removal of tubular workpieces.

[0051] In some embodiments, the extension arm 31 and the clamp body 10 are threadedly connected. The extension arm 31 is assembled and disassembled via a threaded connection, simplifying the assembly and disassembly process and improving the stability of the extension arm 31 fixed to the clamp body 10. Specifically, the extension arm 31 has a stud structure, and the clamp body 10 has a nut structure; or, the extension arm 31 has a nut structure, and the clamp body 10 has a stud structure. In other embodiments, the extension arm 31 and the clamp body 10 may not be threadedly connected, but may be fixed using a separate pin.

[0052] In some embodiments, the extension arm 31 and the clamp body 10 are connected by an interference fit. The interference fit allows for a stable connection between the extension arm 31 and the clamp body 10, and the direct plug-in / plug-out design facilitates assembly and disassembly.

[0053] See Figure 1It is understood that in some embodiments, the clamping head 32 is fixedly disposed on the extension arm 31, which helps to prevent the clamping head 32 from moving relative to the extension arm 31, thereby improving the positional stability of the clamped tubular workpiece relative to the pipe clamp 100 and facilitating the assembly and disassembly of the tubular workpiece. Exemplarily, the clamping head 32 is welded to the extension arm 31.

[0054] In some embodiments, the clamping head 32 has a clamping surface 321. The clamping surface 321 is arc-shaped. The clamping surfaces 321 of the two clamping heads 32 are arranged facing each other. When the two clamping bodies 10 rotate relative to each other, the two clamping surfaces 321 can come closer together to clamp the tubular workpiece. The arc-shaped clamping surface 321 is more likely to conform to the clamped surface 321 of the tubular workpiece, improving the stability of fixing and clamping the tubular workpiece.

[0055] In some embodiments, the shape of the clamping surface 321 of the arc structure is part of a cylindrical surface rather than part of a spherical surface, in order to fit the side of the tubular workpiece.

[0056] See Figure 2 In some embodiments, the axis of the clamping surface 321 is parallel to the axis of the pivot 20. The force exerted by the hand on the clamping body 10 is approximately the same as the force exerted by the clamping surface 321 on the tubular workpiece, which helps to avoid the formation of rotational torque on the tubular workpiece, thereby enabling stable clamping of the tubular workpiece.

[0057] In some embodiments, the side of the clamping surface 321 furthest from the pivot 20 is defined as the far side 3211. The side of the clamping surface 321 closest to the pivot 20 is defined as the near side 3212. The distance between the far sides 3211 of the two clamping surfaces 321 is less than the distance between the near sides 3212 of the two clamping surfaces 321.

[0058] The above structure enables the two clamping heads 32 to form a wedge structure when clamping the tubular workpiece. When a force is applied to clamp the tubular workpiece, the tubular workpiece can be pushed to the far side 3211, producing a tightening effect, which helps to prevent the tubular workpiece from slipping during clamping.

[0059] Understandably, in some embodiments, at least the far side 3211 and the near side 3212 of the clamping surface 321 can abut against the tubular workpiece, thereby enabling the two clamping heads 32 to form more than three clamping contact positions around the tubular workpiece to stably clamp the tubular workpiece.

[0060] In some embodiments, the clamping surface 321 is provided with anti-slip textures (not shown). The anti-slip textures help prevent the tubular workpiece from slipping, improving the stability of clamping and fixing the tubular workpiece. The anti-slip textures are formed at least on the far edge 3211 and near edge 3212 of the anti-slip surface. Exemplarily, the anti-slip textures can be stripe patterns and / or dot patterns.

[0061] It is understood that in some embodiments, the anti-slip texture is spaced along the axis of the clamping surface 321 to improve the anti-slip effect of the clamping surface 321 in the axial direction.

[0062] See Figure 1 and Figure 3 In some embodiments, the extension chuck 30 further includes an adapter 33. The adapter 33 is fixedly mounted on the clamp body 10. The extension arm 31 and the adapter 33 are detachably connected. By adding the adapter 33 to the clamp body 10, the detachable structure that assembles and disassembles with the extension arm 31 does not need to be directly mounted on the clamp body 10, which helps reduce the difficulty of setting up the detachable structure and facilitates the assembly and disassembly of the extension arm 31. It is understood that in some embodiments, the clamp body 10 is a one-piece molded structure, which improves the structural strength of the clamp body 10. By setting the adapter 33, it is convenient to set up a detachable structure that matches the structural adaptability of the extension arm 31.

[0063] In some embodiments, the adapter 33 is welded to the clamp body 10, and the connection structure is stable.

[0064] In some embodiments, the extension arm 31 and the adapter 33 are threadedly connected. The extension arm 31 is assembled and disassembled via a threaded connection, which simplifies the assembly and disassembly process and improves the stability of the extension arm 31 when fixed to the clamp body 10. In other embodiments, the extension arm 31 and the adapter 33 may be fixed by a separate pin instead of a threaded connection.

[0065] Understandably, in some embodiments, the extension arm 31 rotates relative to the clamp body 10, enabling the axis of the clamping surface 321 to be parallel to the axis of the pivot 20.

[0066] Understandably, in some embodiments, the extension arm 31 has a stud structure and the adapter 33 has a nut structure, facilitating the fixing of the adapter 33 to the clamp body 10. In other embodiments, the extension arm 31 has a nut structure and the adapter 33 has a stud structure.

[0067] In some embodiments, the extension arm 31 and the adapter 33 are connected by an interference fit. The interference fit allows for a stable connection between the extension arm 31 and the adapter 33, and the direct plug-in / plug-out design facilitates assembly and disassembly.

[0068] Understandably, in some embodiments, the extension arm 31 is provided with a limiting surface 311. When the extension arm 31 is connected to the adapter 33 or directly connected to the clamp body 10, the limiting surface 311 can abut against the adapter 33 or the clamp body 10, which facilitates the adjustment of the position of the extension arm 31 relative to the clamp body 10, so as to adjust the relative position of the two clamping heads 32, so that the two clamping heads 32 can accurately clamp the two sides of the tubular workpiece.

[0069] In some embodiments, the gripping section 11, the pivoting section 12, and the clamping section 13 are connected in sequence. The adapter 33 is fixedly disposed on the clamping section 13. The assembly position of the extension arm 31 can be far away from the gripping section 11, which on the one hand facilitates delaying the position of the extension chuck 30 clamping the tubular workpiece, and on the other hand helps to avoid the extension chuck 30 affecting the hand's grip on the clamp body 10.

[0070] In some embodiments, the gripping section 11, pivoting section 12, and clamping section 13 of the clamp body 10 are integrally formed. For example, the combination of the clamp body 10 and the pivot 20 can be pliers or needle-nose pliers. It is understood that in some embodiments, the pipe clamp 100 also includes a buffer pad 40; the buffer pad 40 is fitted onto the gripping section 11 to help avoid hand discomfort when gripping the pipe clamp 100.

[0071] See Figure 3 In some embodiments, the end of the clamping section 13 away from the pivot section 12 is provided with a mounting surface 131. The adapter 33 is fixedly disposed on the mounting surface 131. By providing the mounting surface 131, it is easier to achieve a fixed connection of the adapter 33 and improve the fixed stability of the adapter 33.

[0072] Understandably, in some embodiments, the end of the clamping section 13 away from the pivot section 12 is formed into a mounting surface 131 by cutting or grinding. For example, when the combination of the clamp body 10 and the pivot 20 is a pair of pliers or needle-nose pliers, the end of the pliers or needle-nose pliers can be ground 3 to 7 mm to form the mounting surface 131.

[0073] In some embodiments, the tubular workpiece is an air hose. Air hoses can be used in applications such as pneumatic systems, automated equipment, material handling, welding and cutting, cooling and lubrication, testing equipment, environmental protection systems, and energy transmission. Air hoses come in various types, such as PU (Polyurethane) hoses, nylon hoses, and corrugated metal hoses; the materials used for air hoses include rubber, polyurethane, nylon, and metal.

[0074] When air hoses are used in pneumatic control systems, they can be used to drive equipment, such as providing power to cylinders, pneumatic motors, and pneumatic valves, or driving automated equipment such as robotic arms, grippers, and conveyor belts. Air hoses can also be used for precision control, such as connecting solenoid valves and sensors through air hoses to achieve precise control of pressure, flow, and direction (e.g., assembly line positioning).

[0075] When air hoses are used for material conveying, they can be used for the transport of powders or granules, such as in the chemical and food industries, where air hoses are used in pneumatic conveying systems to efficiently transport powder or granular raw materials. Air hoses can also be used for liquid or gas distribution, such as the pneumatic spray gun piping in paint booths and the cooling gas conveying in injection molding machines.

[0076] When gas tubes are used to support precise processing techniques, they can be used for welding and cutting, such as providing protective gases (e.g., argon, nitrogen) for laser cutting machines and plasma welding equipment. Gas tubes can also be used for cooling and lubrication, for example, in CNC (Computerized Numerical Control) machine tools, where coolant atomized gas or lubricating oil is delivered through gas tubes.

[0077] When air hoses are used for testing and cleaning, they can be used for airtightness testing, such as connecting pressure sensors and testing equipment to test product sealing (e.g., automotive parts, battery packs); air hoses can also be used for equipment purging, such as using compressed air to clean molds, electronic components, or production line residues.

[0078] When gas pipes are used in the fields of environmental protection and safety, they can be used for exhaust gas discharge, such as guiding industrial waste gas to treatment devices (such as welding fume collection); gas pipes can also be used for safety protection, such as providing an inert gas isolation environment for explosion-proof equipment.

[0079] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
