Description

Technical Field

[0001] This invention relates to the field of operating tools, and in particular to a clamp and workbench assembly. Background Technology

[0002] A clamp typically has two clamping surfaces: one fixed end and the other movable end. The user can adjust the position of the movable end via an operating mechanism. In traditional clamps, such as those in patent CN211388387U, the operating mechanism is located on different sides of the two clamping surfaces. However, while such clamps are suitable for most applications, in certain specific scenarios, the operating mechanism may interfere with the position of the structure to be clamped or other external structures, affecting the clamp's usability. Summary of the Invention

[0003] In view of this, it is necessary to provide a fixture and worktable assembly.

[0004] This invention provides a clamp, including a rod, a fixed clamp, and a movable clamp. The fixed clamp is fixed to the rod, and the movable clamp is movably mounted on the rod. The fixed clamp includes a first clamping surface, and the movable clamp has a second clamping surface. The first clamping surface and the second clamping surface cooperate to clamp an external structure. The movable clamp also includes an operating part, and the movable clamp can be adjusted to a position on the rod via the operating part. The operating part and the second clamping surface are located on the same side of the rod.

[0005] In one embodiment of the present invention, the movable clamp further includes a second support portion, and the operating portion includes a moving portion and a clamping portion, both of which are mounted on the second support portion; the movable clamp can move along the rod via the moving portion; the movable clamp can move along the rod towards the fixed clamp via the clamping portion and apply a clamping force to the external structure.

[0006] In one embodiment of the present invention, the movable part includes a locking plate and a first elastic member. The locking plate has a second hole, and the locking plate is sleeved on the rod body through the second hole. The first elastic member elastically acts on the locking plate, so that the locking plate clamps the rod body through the inner wall of the second hole. The locking plate can rotate relative to the rod body, and the inner wall of the second hole clamping the rod body gradually moves away from the rod body, so that the movable part can move along the rod body.

[0007] In one embodiment of the present invention, the movable clamp further includes a first support portion, the first support portion sleeves the rod body, and the locking piece and the first elastic member are both installed on the first support portion; the movable portion further includes a toggle member, the toggle member is rotatably connected to the first support portion, and the toggle member can toggle the locking piece, so that the locking piece rotates relative to the rod body.

[0008] In one embodiment of the present invention, the clamping part includes a force-applying handle, a driving plate, and a second elastic element. The driving plate has a third hole, through which the rod is sleeved. The force-applying handle can drive the driving plate to rotate, causing the inner wall of the third hole to clamp the rod and drive the clamping part to move towards the side relatively closer to the fixed clamp. The second elastic element elastically acts on the driving plate and can reset the driving plate and the force-applying handle.

[0009] In one embodiment of the present invention, there are multiple drive plates, one of which can be actuated by the force-applying handle and drive the other drive plates to rotate relative to the rod.

[0010] In one embodiment of the present invention, the clamp further includes a pin, which is fixed to the movable clamp body, and the pin and the operating part are respectively located on opposite sides of the rod body.

[0011] In one embodiment of the present invention, the pin is detachably mounted on the movable clamp.

[0012] In one embodiment of the present invention, the clamp further includes a slider, which is fixed to the movable clamp body, and the pin is fixed to the slider; the slider can drive the movable clamp body to slide in the groove of the external structure.

[0013] In the clamp provided by the present invention, the operating part and the second clamping surface are located on the same side of the rod, which can avoid positional interference between the operating part and the structure to be clamped during use, and at the same time facilitate user operation.

[0014] The present invention also provides a workbench assembly, including a workbench and the above-mentioned clamp, the clamp further including a pin, the workbench having a fixing hole, and the movable clamp being able to be inserted into the fixing hole through the pin and positioned on the workbench.

[0015] The workbench assembly provided by this invention allows the workbench to be used in conjunction with a fixture. The fixture can be installed on the workbench first, and then the structure to be clamped can be clamped, thus expanding the applicable scenarios of the fixture. Attached Figure Description

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the clamp 100 in one embodiment of the present invention; Figure 2 for Figure 1 A partial structural schematic diagram of the fixture 100 shown.

[0026] This invention provides a clamp 100 for holding articles. In this embodiment, the clamp 100 is used for woodworking operations. It is understood that in other embodiments, the clamp 100 can also be applied to other types of applications requiring the holding of articles, such as industrial and household applications.

[0027] The clamp 100 includes a rod 10, a fixed clamp 20, and a movable clamp 30. The fixed clamp 20 is fixed to the rod 10, and the movable clamp 30 is movably mounted on the rod 10. The fixed clamp 20 has a first clamping surface 201, and the movable clamp 30 has a second clamping surface 301. The movable clamp 30 can move along the rod 10 to change the distance between the first clamping surface 201 and the second clamping surface 301, thereby clamping external structures of different sizes.

[0028] The rod 10, the fixed clamp 20, and the movable clamp 30 are all preferably metal parts to improve the mechanical strength of the clamp 100, thereby increasing the clamping force of the clamp 100. The first clamping surface 201 and the second clamping surface 301 are preferably flexible parts, such as rubber parts, to protect the clamped external structure.

[0029] In one embodiment, both the fixed clamp 20 and the movable clamp 30 are fitted with the rod 10, and the movable clamp 30 can move along the rod 10 so that the first clamping surface 201 and the second clamping surface 301 can be aligned with each other. It is understood that in other embodiments, the fixed clamp 20 and / or the movable clamp 30 can also move along the rod 10 by means of a slide rail or other means, and it is not necessary to fit the rod 10.

[0030] A first hole 11 is provided on the rod 10 for mounting and fixing the clamp 20. Preferably, the first hole 11 is located at the end of the rod 10 to increase the maximum size that the clamp 100 can hold. Furthermore, the first hole 11 is provided at both ends of the rod 10, making the use of the clamp 100 more flexible and facilitating the clamp 100 to be supported against the external structure. It can be understood that the first hole 11 can be a through hole or a blind hole.

[0031] Preferably, the clamp 100 further includes a stop protrusion 12, which can be fixed in the first hole 11 at the end of the rod 10 that is relatively close to the movable clamp 30, and the stop protrusion 12 protrudes from the rod 10; the stop protrusion 12 can stop the movable clamp 30 and prevent the movable clamp 30 from sliding off the rod 10.

[0032] The stop protrusion 12 is preferably an elastic cylindrical structure, and the stop protrusion 12 has an opening along the axial direction. The elastic cylindrical structure can change its outer diameter through the opening to facilitate the installation of the stop protrusion 12 in the first hole 11. Of course, the stop protrusion 12 can also be fixed in the first hole 11 by friction or by interference fit. The present invention does not limit the structure and installation form of the stop protrusion 12, as long as it can play a stopping role.

[0033] Please refer to it again. Figure 1 And see also Figure 3 , Figure 3 for Figure 2 The cross-sectional view of section AA shown.

[0034] The fixing clamp 20 includes a pressing part 21 and a first support part 22. The pressing part 21 includes a first pressing member 211, a second pressing member 212, a positioning post 213, and a third elastic member 214. The first pressing member 211 and the second pressing member 212 are fixedly connected, and the first pressing member 211 and the second pressing member 212 are respectively located on both sides of the first support part 22. The positioning post 213 is fixedly disposed in the second pressing member 212. The first support part 22 has a third hole (not shown in the figure), through which the positioning post 213 can pass and extend into the first hole 11. The first pressing member 211 has a mounting groove 2111, and the third elastic member 214 is accommodated in the mounting groove 2111. The two ends of the third elastic member 214 act on the first pressing member 211 and the first support part 22, respectively. It can be understood that the third elastic member 214 can also be disposed in the second pressing member 212, which is not limited here.

[0035] The pressing part 21 is movable relative to the first support part 22, and an installation gap 215 is formed between the fixing post and the first pressing member 211. When the pressing part 21 is in an unforced state, under the action of the third elastic member 214, the positioning post 213 extends into the first hole 11, so that the fixing clamp 20 can be installed on the rod 10. When the pressing part 21 is in a pressed state, the positioning post 213 can be moved out of the first hole 11, so that the rod 10 can be pulled out from the installation gap 215, thereby realizing the separation of the fixing clamp 20 from the rod.

[0036] To reduce manufacturing costs, the first pressing component 211, the second pressing component 212, and the positioning post 213 are formed separately and then fixedly connected. The first pressing component 211 and the second pressing component 212 are preferably connected using threaded fasteners; the second pressing component 212 and the positioning post 213 can be connected using an interference fit, or other common methods such as welding, threaded connection, or adhesive bonding, which will not be listed here. It is understood that the positioning post 213 and the second pressing component 212 can also be formed as a single piece.

[0037] Preferably, the end of the rod 10 where the clamp 20 is mounted also has two first holes 11. The outer first hole 11 is used for mounting the clamp 20, and the inner first hole 11 is used for mounting the stop protrusion 12. When the outer wall of the clamp 20 abuts against the stop protrusion 12, the positioning post 213 can be precisely installed in the first hole 11. This arrangement facilitates the installation of the clamp 20.

[0038] Traditional clamps, such as F-clamps with handles, typically have their handles and clamping surfaces positioned on opposite sides. This can easily cause positional interference with the structure being clamped or the worktable during use, limiting the clamp's applicability. If woodworking operations are desired on a worktable, alternative tools with clamping structures must be used, or a groove must be cut into the edge of the worktable to accommodate the F-clamp's handle, or the first clamping surface must be raised so that the F-clamp's handle can rest on the worktable surface.

[0039] However, the above-mentioned method of using the F-clamp with the worktable is not compatible with existing worktables, or the stability of the F-clamp during use cannot be guaranteed.

[0040] Therefore, please refer to the following: Figure 2 and Figure 4 , Figure 2 for Figure 1 A partial structural diagram of the fixture 100 shown (the cover plate on the movable clamp 30 is omitted to show the internal structure); Figure 4 for Figure 1The clamp 100 shown is a cross-sectional view. In the clamp 100 provided by the present invention, the movable clamp 30 further includes an operation part 302, and the movable clamp 30 can be adjusted on the rod 10 by the operation part 302; the operation part 302 and the second clamping surface 301 are located on the same side of the rod 10.

[0041] Specifically, the operating part 302 includes a moving part 31 and a clamping part 32. The movable clamp 30 also includes a second support part 33. The moving part 31 and the clamping part 32 are both mounted on the second support part 33. The movable clamp 30 can move along the rod 10 via the moving part 31. The movable clamp 30 can move along the rod 10 towards the fixed clamp 20 via the clamping part 32 and apply a clamping force to the clamped structure.

[0042] The movable part 31 includes a locking piece 311 and a first elastic member 312. Both the locking piece 311 and the first elastic member 312 are mounted on the second support part 33. The locking piece 311 has a second hole (not shown in the figure). The locking piece 311 is sleeved on the rod body 10 through the second hole, and the locking piece 311 can rotate relative to the rod body 10. The two ends of the first elastic member 312 abut against the locking piece 311 and the second support part 33, respectively. The first elastic member 312 can cause the locking piece 311 to return to the state where it is locked to the inner wall of the first hole 11 and clamps the rod body 10.

[0043] It is understood that a groove can also be provided on the locking piece 311 instead of a second hole, so that the groove wall can clamp the rod 10. In addition, in an embodiment not shown, the operating part 302 can also be provided with a toggle member, which is hinged to the second support part 33, and the toggle member can move the locking piece 311 so that the locking piece 311 can rotate relative to the rod 10.

[0044] The working principle of the moving part 31 is as follows: In the unloaded state, the locking piece 311 is inclined to the rod 10 under the action of the first elastic member 312, and the inner wall of the second hole can clamp the rod 10. At this time, the moving clamp 30 cannot move away from the fixed clamp 20 relative to the rod 10. When the user presses the locking piece 311, the locking piece 311 rotates and gradually becomes perpendicular to the rod 10, and the inner wall of the second hole gradually moves away from the rod 10. At this time, if the user applies a force along the direction of the rod 10, the moving part 31 can move along the rod 10 in a direction that is relatively closer to or relatively farther away from the fixed clamp 20. When the user releases the locking piece 311, the locking piece 311 returns to its original position under the action of the first elastic member 312, restoring the state in which the inner wall of the second hole clamps the rod 10, thereby realizing the positioning of the moving part 31.

[0045] It should be noted that when the inner wall of the second hole is in the state of clamping the rod 10, if the movable clamp 30 tends to move away from the fixed clamp 20, the inertia will cause the inner wall of the second hole to further clamp the rod 10, ensuring that the movable frame cannot move in a direction relatively away from the fixed clamp 20. Conversely, when the movable clamp 30 tends to move closer to the fixed clamp 20, the inertia will cause the inner wall of the second hole to loosen the rod 10, ensuring that the clamping part 32 can drive the movable clamp 30 to move closer to the fixed clamp 20.

[0046] Preferably, there are at least two locking plates 311, and the actuating member can drive one of the locking plates 311 to rotate, causing the other locking plates 311 to rotate accordingly. This arrangement can improve the clamping force between the locking plates 311 and the rod 10.

[0047] The clamping part 32 includes a force-applying handle 321, a driving plate 322, and a second elastic member 323. The driving plate 322 has a third hole, through which the rod 10 is sleeved. The force-applying handle 321 is hinged to the second support part 33, and the force-applying handle 321 can drive the driving plate 322 to rotate, so that the inner wall of the third hole clamps the rod 10, and drives the clamping part 32 to move towards the side relatively closer to the fixed clamp 20. The second elastic member 323 elastically acts on the driving plate 322, and can reset the driving plate 322 and the force-applying handle 321.

[0048] Specifically, the second support part 33 is provided with a first arc-shaped support surface 331, and the force application handle 321 includes a force application part 3211 and a push part 3212. The force application part 3211 and the push part 3212 are respectively located on both sides of the hinge point between the force application handle 321 and the second support part 33. The force application part 3211 is used for the user to press, and the push part 3212 is provided with a second arc-shaped support surface 32121 that cooperates with the first arc-shaped support surface 331.

[0049] The clamping part 32 operates as follows: When not under force, the driving plate 322 is approximately perpendicular to the rod 10, allowing the rod 10 to move within the third hole, thus preventing the clamping part 32 from affecting the use of the moving part 31. When the user applies force to the force-applying part 3211, the force-applying handle 321 rotates relative to the second support part 33 around the hinge point, driving the driving plate 322 to rotate, causing the inner wall of the third hole on the driving plate 322 to clamp the rod 10. As the force-applying part 3211 rotates towards the side relatively away from the fixed clamp 20, the pushing part 3212 will correspondingly rotate towards the side relatively closer to the fixed clamp 20. The second arc-shaped support surface 32121 can apply a force towards the fixed bracket to the first arc-shaped support surface 331. At this time, the second support part 33 can move towards the fixed bracket with the contact point between the inner wall of the third hole and the rod 10 as the fulcrum. When the user releases the force application part 3211, the drive plate 322 returns to a state that is approximately perpendicular to the rod 10 under the action of the second elastic member 323, and the second elastic member 323 can also push the drive plate 322 to move closer to the fixed bracket to complete one clamping process of the clamping part 32.

[0050] In this invention, the movable clamp 30 can move a wide range along the rod 10 through the movable part 31 and move a small range along the rod 10 toward the fixed clamp 20 through the clamping part 32. It can also apply a clamping force to the structure to be clamped to prevent the structure to be clamped from coming out between the first clamping surface 201 and the second clamping surface 301.

[0051] Preferably, there are at least two drive plates 322, and the force-applying handle 321 can drive one of the drive plates 322 to rotate, and the other drive plates 322 are driven to rotate accordingly. This arrangement can improve the clamping force between the drive plates 322 and the rod 10.

[0052] Preferably, the movable clamp 30 has multiple weight-reducing holes 332 inside to reduce the total weight of the clamp 100, thereby reducing storage and transportation costs and making it easier for users to use.

[0053] In one embodiment, the movable clamp 30 further includes a handle 303, which is fixedly connected to the second support portion 33. The handle 303 is located on the side of the force-applying handle 321 that is relatively away from the fixed clamp 20, and the locking plate 311 is located on the side of the force-applying handle 321 that is relatively close to the fixed clamp 20. It is understood that in other embodiments, the positions of the handle 303, the force-applying handle 321, and the locking plate 311 can be interchanged, and the present invention is not limited thereto. In an embodiment not shown, the locking plate 311 or a toggle element may also be provided on the side of the movable clamp 30 that is relatively away from the fixed clamp 20, similar to the hammer on a pistol.

[0054] Preferably, the handle 303 and the second support portion 33 are integrally formed. It is understood that in other embodiments, the handle 303 and the second support portion 33 can also be formed separately and then fixedly connected.

[0055] To facilitate the installation of the clamp 100 onto the workbench 210 or other external structures, in one embodiment, the clamp 100 further includes a pin 34 fixed to the movable clamp body 30, and the pin 34 and the operating part 302 are located on opposite sides of the rod body 10.

[0056] The process of using the clamp 100 is as follows: First, the clamp 100 is installed on the workbench 210 or other external structure. The user presses the locking piece 311 and pulls the rod 10. The fixed clamp 20 will move with the rod 10 in a direction that is relatively closer to or relatively farther away from the moving clamp 30, thereby significantly changing the distance between the first clamping surface 201 and the second clamping surface 301. Then, the user presses the force application handle 321 so that the first clamping surface 201 and the second clamping surface 301 can apply a clamping force to the clamped structure.

[0057] Specifically, the pin 34 is a metal part, and it is cylindrical with a hollow internal structure, so that the pin 34 can be detachably installed on the second support part 33 by means of threaded fasteners. It is understood that the pin 34 can also be connected to the second support part 33 by other methods such as snap-fit ​​connection, welding, hinge, or tight fit; the pin 34 can also be integrally formed with the second support part 33. Furthermore, by setting the pin 34 to a cylindrical shape, the pin 34 can directly mate with the fixing hole 211 on the worktable 210. Of course, the outer peripheral wall of the pin 34 can also be non-cylindrical to restrict the rotation of the clamp 100 during use.

[0058] In one embodiment, the clamp 100 further includes a slider 35, which is fixed to the movable clamp 30, and a pin 34 is fixed to the slider 35; the slider 35 can drive the movable clamp 30 to slide in the groove of the external structure.

[0059] Specifically, the slider 35 is a metal part, and the slider 35 is installed on the second support part 33. The slider 35 can drive the movable clamp 30 to slide in the groove of the worktable 210 or other external structures.

[0060] Preferably, the slider 35 is detachably mounted to the second support 33 by means of threaded fasteners, and the pin 34 is detachably mounted to the slider 35 by means of threaded fasteners.

[0061] The installation process of the fixture 100 is as follows: First, remove the pin 34 from the slider 35. Then, slide the slider 35 along the groove of the worktable 210 or other external structure to the fixing hole 211. Then, pass the pin 34 through the fixing hole 211 and fix the pin 34 to the slider 35, thereby installing the movable clamp 30 onto the worktable 210 or other external structure. The subsequent usage process is roughly the same as described above and will not be repeated here. With this configuration, the slide rail can prevent the movable clamp 30 from rotating during use, thereby improving the stability of the fixture 100.

[0062] It is understandable that during the use of the fixture 100, it can be installed on the worktable 210 by means of the pin 34 and abutted against the worktable 210 or other external structures by means of the sliding member 35.

[0063] In an embodiment not shown, the pin 34 can also be disposed on the fixed clamp 20, and the distance between the first clamping surface 201 and the second clamping surface 301 can be changed by adjusting the position of the movable clamp 30 on the rod 10. In this case, the movable clamp 30 can slide via the slider 35 or via the end face of the second support member.

[0064] Many woodworking operations require the use of clamps in conjunction with the workbench 210, such as cutting, assembling, grooving, and drilling wood. Based on this, the present invention also provides a workbench assembly 200, including the workbench 210 and the aforementioned clamp 100. The workbench 210 has a fixing hole 211, and the movable clamp 30 can be inserted into the fixing hole 211 via a pin 34 and positioned on the workbench 210. The fixing hole 211 can be a through hole or a blind hole.

[0065] It is understandable that if the existing workbench 210 already has through holes or blind holes for fixing other accessories, these can also be used as fixing holes 211, and there is no need to set up a separate fixing hole 211.

[0066] Preferably, the worktable 210 is also provided with non-cylindrical holes to match non-cylindrical pins 34.

[0067] Preferably, the worktable 210 is also provided with a slide groove to accommodate the sliding member 35.

[0068] In the clamp 100 provided by the present invention, the operating part 302 and the second clamping surface 301 are located on the same side of the rod 10, which can avoid positional interference between the operating part 302 and the structure to be clamped during use, and at the same time facilitate user operation. In the workbench assembly 200 provided by the present invention, the workbench 210 can be used in conjunction with the clamp 100. The clamp 100 can be installed on the workbench 210 first, and then the structure to be clamped can be clamped, thus expanding the applicable scenarios of the clamp 100.

[0069] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
