[0031] This application provides a pipe clamp that enables quick fastening and quick disassembly, see reference. Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a structural schematic diagram of the pipe clamp provided in this application. Figure 2 This is an exploded view of the pipe clamp provided in this application. Figure 3 This is a schematic diagram of the clamping component in the pipe clamp provided in this application. Figure 4 This is a schematic diagram of the blank of the clamping component in the pipe clamp provided in this application. The pipe clamp provided in the embodiments of this application will be described below with reference to the examples in the accompanying drawings.

[0032] The pipe clamp provided in this application includes: a clamping member 1, a connecting member 2, and a wrench 3; wherein, the clamping member 1 includes a clamping part 11 and a connecting part 12, the clamping part 11 is enclosed to form an annulus with an opening, and the two connecting parts 12 are respectively located on one side of the opening of the clamping part 11 and are corresponding to each other, and the clamping member 1 is formed by sheet metal processing; the connecting member 2 is connected to the two connecting parts 12; the wrench 3 is rotatably connected to one end of the connecting member 2 and abuts against one of the connecting parts 12, and by rotating the wrench 3, the connecting member 2 can be driven to move relative to at least one connecting part 12 to change the distance between the two connecting parts 12.

[0033] In this embodiment, the clamping member 1 can surround the locked member (such as a round or square tube with a notch), and the shape of the clamping member 1 can be set according to the shape of the locked member. The clamping member 1 can be configured to include a clamping part 11 and a connecting part 12. The shape of the clamping part 11 matches the locked member, such as setting the clamping part 11 to a semi-circular shape so that an opening is formed between the two ends of the clamping member 1. A connecting part 12 can be connected to each end of the clamping part 11 to connect the clamping member 1 and the connecting member 2 through the connecting part 12. For example, the two connecting parts 12 can be configured to be opposite and parallel or nearly parallel.

[0034] For example, such as Figure 3 and Figure 4 As shown, the clamping component 1 can be made of sheet metal. The shape of the clamping component 1 can be determined by sheet metal processing techniques. For example, a shape can be cut from a single sheet of metal using a shearing process. Figure 4 The clamping component 1 shown is cut into shape and then stamped into a ring-shaped structure including a clamping part 11 and a connecting part 12 by a stamping process.

[0035] In this embodiment of the application, two connecting parts 12 can be connected by a connector 2. For example, the connector 2 can be set as a column, and through holes matching the connector 2 can be provided on the two connecting parts 12 so that a part of the connector 2 passes through the two connecting parts 12. The diameter of one end of the connector 2 can be larger than the diameter of the through hole on the connecting part 12 so that one end of the connector 2 can press against the outer surface of one connecting part 12.

[0036] In this embodiment, the wrench 3 can be used to move the connector 2 relative to the connecting portion 12, thereby changing the size of the ring enclosed by the clamping portion 11. For example, one end of the wrench 3 can be rotatably connected to the other end of the connector 2, and the wrench 3 can be placed against the outer surface of the other connecting portion 12. In this way, the wrench 3 can be rotated to move the connector 2 relative to the connecting portion 12 that abuts against the wrench 3, thereby changing the distance between the two connecting portions 12, thus changing the size of the ring of the clamping portion 11, and thus clamping and locking the locked part.

[0037] The pipe clamp provided in this embodiment features a clamping member 1 with a clamping portion 11 and a connecting portion 12, facilitating the clamping of the locked component via the clamping portion 11. Furthermore, the wrench 3 is connected to the two connecting portions 12 via a connecting member 2, allowing the connecting member 2 to move relative to the connecting portion 12 by rotating the wrench 3. This enables rapid adjustment of the size of the clamping portion 11, facilitating the locking of the locked component. Simultaneously, the clamping member 1 is machined using sheet metal processing. Compared to related technologies where the clamping member 1 is made of aluminum profile and machined, the sheet metal processing of the clamping member 1 in this embodiment improves the processing efficiency of the clamping member 1, thereby increasing the overall processing efficiency of the pipe clamp and reducing its production cost.

[0038] In some possible embodiments of this application, such as Figure 3 and Figure 4 As shown, the clamping member 1 also includes a bending portion 13, and the connecting portion 12 and the clamping portion 11 are connected at an angle through the bending portion 13. The connecting portion 12, the bending portion 13 and the clamping portion 11 are an integral structure.

[0039] In this embodiment, a bending portion 13 may be provided in the clamping member 1 so as to connect the connecting portion 12 and the clamping portion 11 through the bending portion 13, and to connect the connecting portion 12 and the clamping portion 11 at an angle.

[0040] For example, when cutting the clamping part 1 by laser cutting, punching, or other methods, a bent portion 13 can be reserved in the blank of the clamping part 1. That is, a bent portion 13 is reserved at each end of the clamping part 11, and a connecting portion 12 is reserved at the end of each bent portion 13 away from the clamping part 11. In this way, by stamping, the blank of the flat clamping part 1 can be stamped into the required clamping part 1, that is, the clamping part 11 is formed into an open ring, and the bent portion 13 is bent at a large angle so that the connecting portion 12 and the clamping part 11 are connected at an obtuse angle, so that the connecting portion 12, the bent portion 13 and the clamping part 11 can be integrally formed into a structure.

[0041] In another example, the connecting portion 12, the bending portion 13, and the clamping portion 11 each have the same thickness. When blanking the clamping part 1, a metal sheet with uniform thickness can be selected for each part, resulting in a blank for the clamping part 1 with the same thickness for each part. During the stamping process of the blank for the clamping part 1, the thickness of each part of the blank remains essentially unchanged, ensuring that the thickness of each part of the connecting portion 12, the bending portion 13, and the clamping portion 11 in the final clamping part 1 is the same or nearly the same. This not only facilitates the selection of the metal sheet to form the clamping part 1 but also eliminates the need to change the thickness of each part of the blank, thus simplifying the processing technology.

[0042] In the above embodiments, since the clamping member 1 also includes a bending portion 13, during the processing of the clamping member 1 by sheet metal processing, it is convenient to connect the connecting portion 12 and the clamping portion 11 through the bending portion 13, and the bending deformation of the bending portion 13 can make the connecting portion 12 and the clamping portion 11 be in a relatively accurate relative position.

[0043] In some possible embodiments of this application, such as Figure 3 and Figure 4 As shown, the clamping part 11 has a positioning part 14, which cooperates with the locked part to restrict the movement of the clamping part 1 relative to the locked part.

[0044] In this embodiment, a positioning part 14 can be provided on the clamping part 11 to limit the position of the clamping member 1 relative to the locked member. For example, the positioning part 14 can be configured to include a groove, which can be provided on the surface of the clamping part 11 facing the center of the clamping member 1. Alternatively, the positioning part 14 can be configured as a through hole, such as a circular through hole, in which case a protrusion matching the groove or through hole can be provided on the locked member. Furthermore, the positioning part 14 can be configured as a protrusion protruding towards the center of the clamping member 1, in which case a groove or through hole matching the protrusion can be provided on the locked member. Thus, the movement of the clamping member 1 relative to the locked member can be limited by the cooperation of the protrusion and groove, or the protrusion and through hole.

[0045] In the above embodiments, since a positioning part 14 is provided on the clamping part 11, it is convenient to limit the position of the clamping member 1 relative to the locked member by the positioning part 14, so that the pipe clamp can be in a definite and accurate position relative to the locked member, thereby improving the reliability of locking the locked member.

[0046] In some possible embodiments of this application, such as Figure 3 and Figure 4 As shown, the clamping part 11 has a deformation hole 15, which is used to reduce the rigidity of the clamping part 11.

[0047] In this embodiment of the application, a deformation hole 15 can be provided on the clamping part 11 to reduce the rigidity of the clamping part 11. For example, during the blanking process of the clamping part 1, the deformation hole 15 can be machined on the blank so that the clamping part 11 has at least one through hole as the deformation hole 15.

[0048] For example, the deformation hole 15 extends through the clamping portion 11 along its thickness direction, and the major axis of the deformation hole 15 is parallel to the extension direction X of the clamping portion 11. For instance, the deformation hole 15 can be configured as a long strip-shaped through hole, that is, along the thickness direction of the clamping portion 11, the projection of the deformation hole 15 can be approximately rectangular, rhomboid, elliptical, etc. In this way, the major axis of the deformation hole 15 is parallel or nearly parallel to the extension direction X (length direction) of the clamping portion 11, and the minor axis of the deformation hole 15 is parallel or nearly parallel to the width direction Y of the clamping portion 11.

[0049] In another example, the clamping member 1 has at least two deformation holes 15, which are distributed along the extending direction X of the clamping portion 11. Multiple deformation holes 15 can be provided on the clamping portion 11; for example, two, three, four, or other equal numbers of deformation holes 15 can be provided on the clamping portion 11 along the extending direction X, and the multiple deformation holes 15 can be arranged sequentially along the extending direction X. Two rows of deformation holes 15 can be provided along the width direction Y of the clamping portion 11.

[0050] In the above embodiments, since deformation holes 15 are provided on the clamping part 11, during the processing of the clamping part 1, deformation holes 15 can be formed on the blank of the clamping part 1 to reduce the rigidity of the clamping part 11. This not only facilitates the processing of the blank by stamping, but also reduces the rigidity of the clamping part 11, making it easier for the clamping part 11 to deform and clamp the locked part. At the same time, it can also keep the connecting part 12 with high rigidity, which helps to reduce the risk of deformation of the connecting part 12.

[0051] In some possible embodiments of this application, reference is made to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the wrench 3 in the pipe clamp provided in this application. Figure 6 This is a schematic diagram of the flattening and unloading structure of the wrench 3 in the pipe clamp provided in this application. The wrench 3 includes a cam part 31 and a handle part 32. The cam part 31 is rotatably connected to the connecting member 2 via a rotating shaft 4. The distances between the various parts of the surface of the cam part 31 that abut against the connecting member 12 and the rotation axis of the cam part 31 relative to the rotating shaft 4 are not equal. The handle part 32 and the cam part 31 are an integral structure.

[0052] In the embodiments of this application, such as Figure 1 and Figure 5 As shown, the wrench 3 can be configured to include a cam portion 31 and a handle portion 32, so that the wrench 3 is rotatably connected to the connector 2 through the cam portion 31, and force is applied to the wrench 3 through the handle portion 32.

[0053] For example, two cam portions 31 can be provided at one end of the handle portion 32, and the two cam portions 31 can be arranged in parallel, with the gap between the two cam portions 31 being able to accommodate the connector 2. For example, both cam portions 31 can be set as discs, and through holes can be provided on the disc-shaped cam portions 31, the center of which does not coincide with the center of the disc-shaped cam portion 31.

[0054] In another example, a rotating shaft 4 that matches the through holes on the cam portion 31 can be used to rotatably connect the cam portion 31 and the connecting member 2. That is, the rotating shaft 4 is inserted into the through holes on both cam portions 31, and then the connecting member 2 is connected to the rotating shaft 4. For example, the connecting member 2 and the rotating shaft 4 can be connected by a threaded connection. This allows the distances between the various parts of the circumferential surface of the cam portion 31 and the axis of rotation of the cam portion 31 relative to the rotating shaft 4 to be unequal.

[0055] Another example, such as Figure 6 As shown, the wrench 3 can be formed by sheet metal processing. For example, the blank of the wrench 3 can be formed by cutting from a whole sheet of metal, and then the blank of the wrench 3 can be stamped into the required shape by stamping, so that the cam part 31 and the handle part 32 are integrated into one structure.

[0056] In the above embodiments, since the wrench 3 includes a cam portion 31 and a handle portion 32, it is convenient to drive the cam portion 31 to rotate relative to the connecting portion 12 via the handle portion 32. This causes the distances between the various parts of the surface of the cam portion 31 abutting against the connecting portion 12 and the rotation axis of the cam portion 31 relative to the rotation shaft 4 to be unequal. During the rotation of the cam portion 31 relative to the connecting portion 12, the rotation shaft 4 can be driven to move relative to the connecting portion 12 along the axial direction of the connector 2, thereby conveniently changing the distance between the two connecting portions 12. Furthermore, by machining the cam portion 31 and the handle portion 32 using sheet metal processing, the cam portion 31 and the handle portion 32 can be integrated into a single structure, which is beneficial for improving the processing efficiency of the handle portion 32.

[0057] In some possible embodiments of this application, such as Figure 5 and Figure 6 As shown, the wrench 3 also includes a torsion part 33. One end of the handle part 32 is connected to two torsion parts 33. Along the width direction Y of the handle part 32, the two torsion parts 33 are located on one side of the handle part 32 respectively. The end of each torsion part 33 away from the handle part 32 is connected to a cam part 31.

[0058] In this embodiment of the application, when cutting the wrench 3, a torsion portion 33 can be reserved in the blank of the wrench 3. For example, the overall shape of the blank of the wrench 3 can be set to an approximate "Y" shape, that is, two torsion portions 33 are provided at one end of the handle portion 32, and a cam portion 31 is provided at the end of each torsion portion 33 away from the handle portion 32. Through the stamping process, the flat blank of the wrench 3 can be stamped into the required shape to obtain a wrench 3 including the wrench 3, two cam portions 31, and two torsion portions 33.

[0059] For example, the torsion part 33 includes a first end 331, a second end 332, and a torsion surface 333. The first end 331 is connected to the handle part 32, and the second end 332 is connected to the cam part 31. The major axis of the first end 331 and the major axis of the second end 332 are perpendicular to each other. The torsion surface 333 is the surface between the first end 331 and the second end 332, and the torsion surface 333 is a continuous curved surface. During the stamping process of the wrench 3, the two cam parts 31 can be rotated from the same plane through the torsion part 33 and brought closer to each other until the two cam parts 31 are parallel to each other. During this process, the torsion part 33 gradually twists, that is, the second end 332 of the torsion part 33 rotates 90° or close to 90° relative to the first end 331, so that the surface between the first end 331 and the second end 332 is formed as a continuously curved surface.

[0060] In the above embodiment, since the wrench 3 also includes a torsion part 33, during the sheet metal processing of the wrench 3, the cam part 31 and the wrench 3, which are on the same plane, can be torsion through the torsion part 33, so that the torsion part 33 and the handle part 32 are in a perpendicular or nearly perpendicular relative position.

[0061] In some possible embodiments of this application, such as Figure 1 and Figure 2 As shown, the pipe clamp also includes a pad 5, which is sleeved on the connector 2 and located between the cam portion 31 and the connector 12. The surface of the pad 5 facing the cam portion 31 is a curved surface that matches the cam portion 31.

[0062] In this embodiment, a spacer 5 can be provided between the cam portion 31 and the connecting portion 12. For example, the surface of the spacer 5 facing the connecting portion 12 can be configured to match the shape of the connecting portion 12, such as making the surface of the spacer 5 facing the connecting portion 12 a flat surface. The side of the spacer 5 facing the cam portion 31 can be configured to match the shape of the surface of the cam portion 31, such as making the side of the spacer 5 facing the cam portion 31 a recessed arc surface that matches the shape of the surface of the cam portion 31. A spacer 6 can also be provided between the connector 2 and another connecting portion 12, and this spacer 6 can be a flat spacer 6.

[0063] In the above embodiment, since a pad 5 is provided between the cam portion 31 and the connecting portion 12, the wear of the cam portion 31 and the connecting portion 12 can be reduced by the pad 5, and the contact area between the connecting portion 12 and the pad 5 can be increased. The contact area between the pad 5 and the cam portion 31 can be increased, which helps to reduce the risk of deformation caused by force concentration in the connecting portion 12.

[0064] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
