Description

Technical Field

[0001] This utility model relates to a multi-head quick clamp. Background Technology

[0002] One type of quick clamp is the trigger-type F-clamp, which uses a trigger mechanism to control the opening and closing of the clamp, allowing the user to clamp or release the workpiece.

[0003] The working principle of a trigger-type F-clamp typically involves a drive handle and a connected transmission system. When the user operates the handle, it activates the transmission system, which in turn pushes the two clamps closer together or further apart to clamp / release.

[0004] Existing designs typically place the drive handle on one side of the linkage, while the clamping working area (fixed chuck and movable chuck) is located on the other side. This "left-right separation" layout requires a large space during operation, making it unsuitable for space-constrained applications, such as when workpieces need to be clamped inside drawers or cabinets.

[0005] Therefore, it is particularly important to provide an improved multi-head quick clamp based on the shortcomings of existing technology. Summary of the Invention

The snap-fit ​​fixing part is provided with a first snap-fit ​​structure and a second snap-fit ​​structure. A driving device includes a base and a driving handle disposed on one side of the base, wherein the driving device has a second guide connection hole penetrating the base; A snap-on switch is provided on the base; The connecting rod passes through the first guide connection hole and the second guide connection hole. The first clamping part and the second clamping part are located on the same side of the connecting rod. The snap-fit ​​switch is configured to snap into the first snap-fit ​​structure or the second snap-fit ​​structure. The drive handle is configured to drive the connecting rod to move along a first direction to bring the first clamping part closer to the second clamping part. When the snap-fit ​​switch snaps into the first snap-fit ​​structure, the drive handle and the second clamping part are located on the same side of the connecting rod. When the snap-fit ​​switch snaps into the second snap-fit ​​structure, the drive handle and the second clamping part are located on opposite sides of the connecting rod.

[0008] In some embodiments, the base is provided with mounting holes; The snap-fit ​​switch is disposed in the mounting hole. The snap-fit ​​switch includes an operating part, a middle part and a snap-fit ​​part connected in sequence. The middle part is rotatably connected to the base. The operating part is exposed in the mounting hole. The operating part can drive the snap-fit ​​part to snap into or out of the first snap-fit ​​structure or the second snap-fit ​​structure.

[0009] In some embodiments, the snap-on switch further includes a switch elastic element that applies an elastic force to the snap-on portion to maintain it in engagement with the first snap-on structure or the second snap-on structure.

[0010] In some embodiments, the operating part is provided with anti-slip features.

[0011] In some embodiments, both the first snap-fit ​​structure and the second snap-fit ​​structure are groove-shaped structures that match the snap-fit ​​portion.

[0012] In some embodiments, the first snap-fit ​​structure and the second snap-fit ​​structure are respectively located on both sides of the first guide connection hole.

[0013] In some embodiments, the drive device further includes: A first locking plate is disposed in the base and sleeved on the connecting rod.

[0014] In some embodiments, the second connecting portion is provided with a receiving groove; The multi-head quick clamp also includes a second locking piece and a second elastic element disposed in the receiving groove. The second locking piece is sleeved on the connecting rod and is in a one-way locking state with the connecting rod. In the one-way locking state, the connecting rod is only allowed to move in the first direction. The second elastic element is installed in the receiving groove and applies an elastic force to the second locking piece to keep it in a one-way locking state with the connecting rod.

[0015] In some embodiments, it also includes: A release element is connected to the second locking plate. Rotation of the release element can cause the second locking plate to rotate and disengage from the connecting rod.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0026] like Figures 1-4 As shown, this embodiment discloses a multi-head quick clamp, which includes a connecting rod 1, a first clamp 2, a second clamp 3, a driving device 4, and a snap-fit ​​switch 5.

[0027] Link 1 is a cylindrical or square rod-shaped structure.

[0028] The first chuck 2 includes a first clamping part 21 and a first connecting part 22 fixedly connected to the connecting rod 1. The first chuck 2 moves synchronously with the connecting rod 1.

[0029] The second clamp 3 includes a second clamping part 31, a second connecting part 32, and a snap-fit ​​fixing part 33. The second clamp 3 has a first guide connecting hole penetrating the second connecting part 32 and the snap-fit ​​fixing part 33. The snap-fit ​​fixing part 33 is provided with a first snap-fit ​​structure 331 and a second snap-fit ​​structure 332. The snap-fit ​​fixing part 33 refers to the connecting structure on the second clamp 3 used for positioning the drive device 4. Specifically, it can be implemented using a metal block with a positioning groove. The first snap-fit ​​structure 331 and the second snap-fit ​​structure 332 correspond to different installation orientations.

[0030] The drive device 4 includes a base 41 and a drive handle 42 disposed on one side of the base 41. The drive device 4 has a second guide connection hole that passes through the base 41.

[0031] The latching switch 5 is located on the base 41. The latching switch 5 is a locking mechanism used to switch the working mode of the fixture, and the orientation of the drive handle 42 is adjusted by changing the latching position.

[0032] The connecting rod 1 passes through the first guide connection hole and the second guide connection hole. The first clamping part 21 and the second clamping part 31 are located on the same side of the connecting rod 1. The snap-on switch 5 is configured to snap into the first snap-on structure 331 or the second snap-on structure 332. The drive handle 42 is configured to drive the connecting rod 1 to move along the first direction to bring the first clamping part 21 closer to the second clamping part 31. When the snap-on switch 5 snaps into the first snap-on structure 331, the drive handle 42 and the second clamping part 31 are located on the same side of the connecting rod 1. When the snap-on switch 5 snaps into the second snap-on structure 332, the drive handle 42 and the second clamping part 31 are located on opposite sides of the connecting rod 1.

[0033] Specifically, when a compact layout is required, the latching switch 5 is operated to engage with the first latching structure 331. At this time, the drive handle 42 and the clamping part are located on the same side of the connecting rod 1, and the overall width of the clamp is reduced to the size of the clamping part on one side. When the operating space needs to be expanded, the latching switch 5 is switched to the second latching structure 332, and the drive handle 42 is rotated to the other side of the connecting rod 1. At this time, the clamping part and the drive handle 42 form an opposing layout. The connecting rod 1 maintains linear motion under the constraint of the double guide holes. The drive handle 42 pushes the connecting rod 1 through the lever principle, causing the first clamping part 21 to move. The positioning function of the latching structure ensures the structural stability in both working modes.

[0034] Compared with existing technologies, the drive handle 42 of traditional clamps is fixedly located on the opposite side of the clamping part, and the layout cannot be adjusted according to the space available. This solution, through a switchable snap-fit ​​structure, allows the same clamp to change the position of the drive handle 42 according to the working conditions. While maintaining the clamping function, it can adopt a compact layout in narrow spaces and an extended layout in regular spaces, breaking through the limitations of traditional structures on the application scenarios.

[0035] Through the above technical solution, this embodiment effectively solves the operational challenge of the clamp within a limited space. The adjustable drive handle 42 layout allows the clamp to adapt to working environments of different sizes. In narrow spaces such as inside drawers, a compact layout is used, with the drive handle 42 positioned on the same side as the clamping part to avoid interference with surrounding structures. In open spaces, an extended layout is used, with the drive handle 42 and the clamping part positioned on opposite sides to provide greater operating torque. This bidirectional adjustable structure significantly improves the clamp's spatial adaptability, meeting diverse working conditions without the need to change tools.

[0036] This embodiment further proposes that the base 41 is provided with a mounting hole. The snap-fit ​​switch 5 is disposed in the mounting hole. The snap-fit ​​switch 5 includes an operating part 51, a middle part 52 and a snap-fit ​​part 53 connected in sequence. The middle part 52 is rotatably connected to the base 41. The operating part 51 is exposed in the mounting hole. The operating part 51 can drive the snap-fit ​​part 53 to engage or disengage from the first snap-fit ​​structure 331 or the second snap-fit ​​structure 332.

[0037] The mounting hole refers to a recessed space on the surface of the base 41, which can be a circular through hole or a rectangular groove to accommodate the snap-fit ​​switch 5 and limit its range of motion. The operating part 51 is a pressing component located within the mounting hole, which can be a raised block with anti-slip texture, its exposed end face flush with or slightly protruding from the opening of the mounting hole. The intermediate part 52 is a transition structure connecting the operating part 51 and the snap-fit ​​part 53, its rotation axis being perpendicular to the side wall plane of the base 41. The snap-fit ​​part 53 is a locking component with a hook-like structure at its end, its hook-like end face forming an interference fit with the groove of the snap-fit ​​structure.

[0038] Through the above technical solution, the snap-on switch 5 in this embodiment is completely built into the mounting hole, and the hidden layout eliminates the space occupied by the protruding structure.

[0039] This embodiment further proposes that the snap-on switch 5 also includes a switch elastic element, which applies an elastic force to the snap-on portion 53 to keep it snapped with the first snap-on structure 331 or the second snap-on structure 332.

[0040] Among them, the switch elastic element refers to the mechanical element that can produce elastic deformation, which can be a helical spring, a disc spring or an elastic metal sheet.

[0041] Compared to the existing technology where switching requires two hands, this embodiment enables state switching to be completed with a single hand press, significantly improving operational efficiency.

[0042] This embodiment further proposes that the operating part 51 be provided with anti-slip features. Anti-slip features refer to structures that alter the surface friction coefficient of the operating part 51 through physical structure. Specifically, this can be achieved by surface knurling, regularly arranged raised particles, or a layer of elastic material. Its function is to increase the resistance of the finger contact surface. The anti-slip features directly act on the outer contour area of ​​the operating part 51, reducing the probability of hand slippage during operation through mechanical structural intervention.

[0043] Through the above technical solution, this embodiment effectively eliminates the risk of misoperation caused by hand slippage, ensuring that the snap-on switch 5 can reliably complete state switching under various working conditions.

[0044] This embodiment further proposes that both the first snap-fit ​​structure 331 and the second snap-fit ​​structure 332 are groove-shaped structures that match the snap-fit ​​part 53. Matching means that the geometric parameters of the snap-fit ​​part 53 structure and the groove-shaped structure are adapted. Specifically, it can be achieved by using a curved surface transition or a sloped guide structure, so that the snap-fit ​​part 53 can be accurately embedded in the groove on the movement trajectory.

[0045] Through the above technical solution, this embodiment solves the problem of clamping failure caused by unstable fit when the snap-fit ​​structure switches working states. The mechanical interlock formed by the groove structure can prevent axial displacement or radial deflection of the snap-fit ​​part 53 during clamping, ensuring continuous and stable transmission of clamping force.

[0046] This embodiment further proposes that the first snap-fit ​​structure 331 and the second snap-fit ​​structure 332 are located on both sides of the first guide connection hole, respectively.

[0047] Through the above technical solution, this embodiment enables the drive handle 42 to switch between the two layout modes more easily.

[0048] This embodiment further proposes that the driving device 4 also includes a first locking piece 43 and a first elastic element 44.

[0049] The first locking plate 43 is disposed within the base 41 and is sleeved on the connecting rod 1. Rotating the drive handle 42 can cause the first locking plate 43 to rotate and engage with the connecting rod 1. The first elastic element 44 is installed within the base 41 and applies an elastic force to the first locking plate 43 to keep it disengaged from the connecting rod 1.

[0050] Specifically, when the drive handle 42 is pressed, its rotation causes the first locking plate 43 to rotate. The first locking plate 43 generates friction with the surface of the connecting rod 1 and forms a one-way engagement. At this time, the connecting rod 1 is restricted by the locking plate to move only in one direction. When the handle is released, the rebound force of the first elastic element 44 pushes the first locking plate 43 to rotate in the opposite direction and return to the state of being disengaged from the connecting rod 1.

[0051] Through the above technical solution, this embodiment can easily and quickly drive the connecting rod 1 to move in the first direction by repeatedly rotating the drive handle 42, so as to reduce the distance between the first clamping part 21 and the second clamping part 31, and finally complete the clamping action.

[0052] This embodiment further proposes that the second connecting part 32 is provided with a receiving groove, and the multi-head quick clamp also includes a second locking piece 6 and a second elastic member 7 disposed in the receiving groove. The second locking piece 6 is sleeved on the connecting rod 1 and is in a one-way locking state with the connecting rod 1 by default. In the one-way locking state, the second locking piece 6 only allows the connecting rod 1 to move in the first direction to drive the first clamping part 21 closer to the second clamping part 31, and does not allow the connecting rod 1 to move in the opposite direction. The second elastic member 7 is installed in the receiving groove and applies an elastic force to the second locking piece 6 to keep it locked with the connecting rod 1.

[0053] Through the above technical solution, in this embodiment, the second locking piece 6 is sleeved on the connecting rod 1 and maintains a unidirectional snap-fit ​​installation method, ensuring that the connecting rod 1 can only move in a preset direction. Furthermore, the second locking piece 6 and the second elastic element 7 are completely integrated into the receiving groove of the second connecting part 32, thereby optimizing the spatial distribution.

[0054] This embodiment further proposes that the multi-head quick clamp also includes a release member 8 connected to the second locking plate 6. The rotation of the release member 8 can drive the second locking plate 6 to rotate and disengage from the connecting rod 1, so that the second locking plate 6 allows the connecting rod 1 to move in the first direction or in the opposite direction, thereby enabling quick adjustment of the distance between the first clamping part 21 and the second clamping part.

[0055] This embodiment further proposes that the multi-head quick clamp drive device 4 also includes a fixed handle 9, which is disposed on the same side of the base 41 as the drive handle 42, and the fixed handle 9 and the drive handle 42 are spaced apart and extend in the same direction.

[0056] The fixed handle 9 is a gripping component rigidly connected to the base 41. Specifically, it can be a metal rod bent and welded to the side wall of the base 41 to provide a fulcrum for force application during operation. The spacing setting refers to maintaining a preset distance between the two handles to avoid collisions and interference during operation.

[0057] Extending in the same direction means that the gripping directions of the two handles are parallel.

[0058] The drive handle 42 and the fixed handle 9 are integrated onto the same side of the base 41, allowing force to be applied by simultaneously gripping both handles with one hand during operation. The fixed handle 9 serves as a rigid support point, while the drive handle 42 rotates to move the connecting rod 1. The parallel arrangement of the two handles ensures that the direction of force transmission is consistent. Furthermore, the distance between the fixed handle 9 and the drive handle 42 is set to be greater than the width of the palm, ensuring that the fingers can be naturally separated when gripping.

[0059] Through the above technical solution, this embodiment improves the efficiency of single-handed operation by using a parallel grip design in which the drive handle 42 and the fixed handle 9 extend in the same direction.
