Description

Technical Field

[0001] This utility model relates to the technical field of clamping structure, and more particularly to a universal adjustable clamping cylindrical rod clamp and a universal connector clamp for quick locking and unlocking. Background Technology

[0002] Currently, production lines for mechanical equipment require numerous clamps to hold cylindrical rods in place. Components are then mounted on these rods to achieve various functions, such as guide wheels, positioning wheels, photoelectric sensors, and cutting blades at the ends of the rods. This facilitates automated production, particularly on lines producing paper bags, tote bags, and other packaging bags. These clamps are typically fixedly mounted on columns, supports, or bases within the production line to hold the cylindrical rods in place. Traditional clamps have significant defects in terms of mechanical structure, material selection and heat treatment processes. They also have some problems in locking and releasing cylindrical rods during clamping. Specifically, the problems of these clamp structures in actual use are as follows: (1) After clamping cylindrical rods, the angle adjustment of cylindrical rods is limited due to the limitations of the clamp structure (after the cylindrical rods are clamped, some protruding structures or bolt positions of the clamp will obstruct the tail end or side of the cylindrical rods, preventing the cylindrical rods from being adjusted at any angle on a plane). The cylindrical rods cannot be adjusted at a wide range, making the adjustment angle of the cylindrical rods narrow and failing to achieve the effect of unlimited use on the production line. (2) When the clamp locks or releases the cylindrical rod, it is necessary to use locking screws, locking nuts, washers, etc. This locking and releasing structure is not only troublesome to operate, but also results in a large number of locking parts. At the same time, it is necessary to use two locking and releasing tools to achieve the desired result, which is inconvenient to operate and fails to achieve the quick locking and releasing of the cylindrical rod by the clamp. (3) When multiple cylindrical rods in the same direction need to be installed on a production line, or multiple cylindrical rods need to be installed at the same center point, multiple fixed columns for clamp installation are often installed on the production line. That is, one fixed column can only install one clamp and one cylindrical rod. Thus, when multiple cylindrical rods are required to be installed, multiple fixed columns are required, resulting in an excessive number of fixed columns and restricting the layout of other parts on the production line. This makes the overall layout of the parts on the production line unreasonable. Furthermore, the number and angle of the fixed columns need to be set separately, which prevents the installation of certain parts on the production line and restricts the installation of other parts. The overall layout of the production line is unreasonable and has many restrictions. (4) After clamping the cylindrical rod, the fixture clamps the surface of the cylindrical rod through its own clamping hole and locks it with screws, etc. When producing this type of fixture structure, the clamping hole is mostly a closed hole structure and iron-based metal material is selected. After heat treatment process, the fixture does not have good elastic deformation ability. When locking the cylindrical rod, it is difficult for the cylindrical rod to be smoothly inserted into the clamping hole, and when the cylindrical rod is released, the clamping hole cannot automatically spring open or release, making it difficult for the cylindrical rod to be easily removed from the clamping hole. (5) The fixture of traditional structure is generally more complex and has a large weight, and the overall structure is very bulky.

[0003] Therefore, it is necessary to improve the existing clamping structure and develop a connector clamp that can flexibly adjust the clamping direction of the cylindrical rod and adjust the maximum angle. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a universal connector clamp. This universal connector clamp can lock or release the rotating connectors by passing a locking bolt through at least two single rotating connectors (used in pairs). It can also clamp a cylindrical rod with a single rotating connector and adjust the rotation angle of the cylindrical rod in a plane by 360 degrees. In principle, multiple clamps can be used to adjust the angle of multiple cylindrical rods in multiple directions, so as to achieve the purpose of universal adjustment of the positioning wheel and other components installed at the end of the cylindrical rod. This universal connector clamp also has a small weight and a very compact appearance. The reasonable selection of metal materials and heat treatment process, as well as the setting of slotted grooves and cylindrical rod through-hole notches, give the clamp good elastic deformation ability, solving the problem of difficult locking and releasing in the use of traditional clamps.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a universal connector clamp, including at least two rotating connectors that can rotate 360 ​​degrees along a plane and are arranged and spliced ​​in sequence, and locking bolts that pass through each rotating connector in sequence and can lock or loosen each rotating connector; the rotating connector is provided with locking bolt holes that allow the locking bolts to pass through, and cylindrical rod through slots that are arranged in the XY axis with the locking bolt holes and allow cylindrical rods to pass through; the two ends of the rotating connector are respectively provided with a first locking plane and a second locking plane that form mutual frictional contact and locking with the end faces of adjacent rotating connectors, and the two ends of the locking bolt holes are respectively located on the first locking plane and the second locking plane.

[0006] Furthermore, the rotating connector is provided with a slotted opening that extends through the top of the rotating connector to the through-hole of the cylindrical rod and cuts off the locking bolt hole.

[0007] Furthermore, the bottom of the rotating connector is provided with a cylindrical rod through-hole notch that is recessed inward to 1 / 2 the depth of the cylindrical rod through-hole.

[0008] Furthermore, the first locking plane is formed by sequentially connecting a semi-circular plane and a rectangular plane to create an integrally connected plane.

[0009] Furthermore, the second locking plane is formed by sequentially connecting a semi-circular plane, a square plane, and a rectangular plane to create an integral, connected plane.

[0010] In summary, the universal connector clamp of this utility model can achieve locking or unlocking between rotating connectors by passing a locking bolt through at least two single rotating connectors (used in pairs). It also allows a single rotating connector to clamp a cylindrical rod and adjust its 360-degree rotation angle within a single plane. Furthermore, in principle, multiple clamps can achieve multi-directional angle adjustment of multiple cylindrical rods, enabling the universal adjustment of the positioning wheels and other components mounted at the ends of the cylindrical rods. This universal connector clamp also features low weight and a very compact appearance. The selection of appropriate metal materials and heat treatment processes, along with the inclusion of slotted grooves and cylindrical rod through-hole notches, gives the clamp excellent elastic deformation capabilities, solving the problem of difficult locking and unlocking in traditional clamps.

[0011] The beneficial effects of this universal connector clamp are as follows:

[0012] (1) When used in pairs, the clamps formed by the two rotating connectors lock and release synchronously, making the operation quick and effortless;

[0013] (2) When used in pairs, the clamps composed of two rotating connectors can be adjusted to any position relative to each other in a plane when they are in the loose state, and can achieve the splicing and extension effect of multiple cylindrical rods in multiple directions, so as to achieve the purpose of universal connection and adjustment.

[0014] (3) Reliable locking and unlocking can be achieved by using a single fastener such as a locking bolt. The structure is simple, the parts are small, and the service life is long. Attached Figure Description

[0027] Example 1

[0028] The universal connector clamp described in Embodiment 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, it includes two rotating connectors 1 that can rotate 360 ​​degrees along a plane and are arranged and spliced ​​in sequence, and locking bolts 2 that pass through each rotating connector in sequence and can lock or loosen each rotating connector; the rotating connectors are provided with locking bolt holes 3 that allow the locking bolts to pass through, and cylindrical rod through slots 4 that are arranged in the XY axis with the locking bolt holes and allow cylindrical rods 9 to pass through; the two ends of the rotating connectors are respectively provided with a first locking plane 5 and a second locking plane 6 that form mutual frictional contact and locking with the end faces of adjacent rotating connectors, and the two ends of the locking bolt holes are respectively located on the first locking plane and the second locking plane. When not locked together, the two rotary connectors can rotate 360 ​​degrees relative to each other in a plane. In use, one rotary connector is inserted through the slot of a cylindrical rod onto a fixed cylindrical rod installed on the production line. The other rotary connector allows for 360-degree rotation of a movable cylindrical rod, enabling flexible application of components mounted at the end of the movable cylindrical rod on the production line. All rotary connectors can be locked or unlocked with a single locking bolt. Furthermore, the two contact surfaces of the rotary connectors are designed as a first locking plane and a second locking plane. During locking, the locking planes of adjacent rotary connectors rub against each other (with a sufficiently large contact friction area), allowing both rotary connectors to be locked with a single locking bolt. This eliminates the need for nuts, washers, and other components, saving on connectors, reducing the weight of the entire fixture, simplifying installation, and streamlining operation.

[0029] In this embodiment 1, the rotating connector is provided with a slotted groove 7 that extends through the top of the rotating connector to the through-hole of the cylindrical rod and cuts off the locking bolt hole. The slotted groove and the use of appropriate metal materials and heat treatment processes give the rotating connector strong elastic deformation capability. When the cylindrical rod is inserted into the through-hole of the rotating connector, tightening or loosening the locking bolt allows for locking and unlocking operations. This enables the use of the cylindrical rod in a clamped state on the production line and allows for angle adjustment when the cylindrical rod is loosened.

[0030] In this embodiment 1, the bottom of the rotating connector is provided with a cylindrical rod through-hole notch 8 that is recessed inward to half the depth of the cylindrical rod through-hole. The cylindrical rod through-hole notch is provided to ensure that the cylindrical rod through-hole still has strong clamping and fixing performance while reducing the overall weight of the clamp.

[0031] In this embodiment 1, the first locking plane is formed by sequentially connecting a semi-circular plane and a rectangular plane to create an integrally connected plane. The first locking plane has a large planar area, achieving a large end-face contact area and a large frictional contact surface when installing adjacent rotating connectors. This allows for the locking of all rotating connectors without the need for nuts and washers, requiring only a single locking bolt.

[0032] In this embodiment 1, the second locking plane is formed by sequentially connecting a semi-circular plane, a square plane, and a rectangular plane to create a single, interconnected plane. The effect of this second locking plane is essentially the same as that of the first locking plane described above.

[0033] In this embodiment 1, as Figure 8 As shown, four rotating connectors can be used to form an interlocking installation, achieving clamping installation of four cylindrical rods. This allows for installation of different cylindrical rods in three or four directions, overcoming the drawback of traditional methods where each cylindrical rod requires a fixed bracket or other fastener for support on the production line. Figure 10 and Figure 11 As shown, multiple cylindrical rods in different directions can be installed at the same point to allow different components (such as positioning wheels) to be used on the production line. Additionally, multiple cylindrical rods can be spliced ​​together to achieve multi-dimensional angle settings, similar to the effect of universal angle adjustment.

[0034] In this embodiment 1, the universal connector clamp can lock or release the rotating connectors by passing a locking bolt through at least two single rotating connectors (used in pairs). It can also clamp a cylindrical rod with a single rotating connector and adjust the 360-degree rotation angle of the cylindrical rod in one plane. In principle, multiple clamps can be used to adjust the angle of multiple cylindrical rods in multiple directions, achieving the purpose of universal adjustment of the positioning wheel and other components installed at the end of the cylindrical rod. This universal connector clamp also has a small weight and a very compact appearance. The reasonable selection of metal materials and heat treatment processes, as well as the setting of slotted grooves and cylindrical rod through-hole notches, give the clamp good elastic deformation ability, solving the problem of difficult locking and releasing in the use of traditional clamps.

[0035] In this embodiment 1, the beneficial effects of the universal connector clamp are as follows:

[0036] (1) When used in pairs, the clamps formed by the two rotating connectors lock and release synchronously, making the operation quick and effortless;

[0037] (2) When used in pairs, the clamps composed of two rotating connectors can be adjusted to any position relative to each other in a plane when they are in the loose state, and can achieve the splicing and extension effect of multiple cylindrical rods in multiple directions, so as to achieve the purpose of universal connection and adjustment.

[0038] (3) Reliable locking and unlocking can be achieved by using a single fastener such as a locking bolt. The structure is simple, the parts are small, and the service life is long.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the structure of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
