Description
Technical Field
[0001] This utility model relates to the field of disassembly tools, specifically to a tool for a hydraulic quick-release connector of a cigarette packaging machine. Background Technology
[0002] Cigarette packaging machines, as key equipment in tobacco product manufacturing, are characterized by complex structures, high operating speeds, and a high degree of automation. During the cigarette packaging process, hydraulic couplings are often used to connect and control multiple hydraulic system modules to enable rapid replacement, maintenance, or repair of equipment components. Hydraulic couplings offer advantages such as strong connections, good sealing performance, and convenient assembly and disassembly, and are therefore widely used in various parts of cigarette packaging machines.
[0003] However, existing hydraulic couplings still present some problems during use. First, hydraulic couplings are mostly located inside equipment or in confined spaces, making manual disassembly and assembly difficult, which can easily lead to wasted manpower or misoperation. Second, due to the high pressure in the hydraulic system, some couplings are tightly connected, and using traditional pliers or other general-purpose tools for disassembly and assembly can easily damage the couplings or even cause leaks.
[0004] In view of the above, in order to overcome the above technical problems, this utility model designs a tool for a hydraulic quick-release connector for a cigarette packaging machine, which solves the above technical problems. Summary of the Invention
[0005] The technical objective of this invention is to provide a tool for a hydraulic quick-release connector for a cigarette packaging machine, aiming to overcome the technical problem of inconvenient disassembly and assembly of hydraulic connectors in the prior art, realize the quick disassembly and installation of hydraulic connectors, and improve the maintenance efficiency and operational safety of cigarette packaging equipment.
[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution:
[0007] This utility model provides a tool for a hydraulic quick-release connector of a cigarette packaging machine, including a positioning rod, a movable rod, and an operating rod. One end of the positioning rod has a positioning catch that contacts the fixed end of the hydraulic connector, and the other end has a hinge. One end of the movable rod has a movable catch that contacts the movable end of the hydraulic connector, and the other end has a hinge. The operating rod has a gripping rod at one end and a connecting rod at the other end. The connecting rod connects the positioning rod and the movable rod through the hinge. Both the positioning rod and the movable rod are horizontally positioned relative to the vertically arranged hydraulic connector.
[0008] Furthermore, the two connecting rods intersect each other, and the intersection is hinged to form a shear section.
[0009] Specifically, the connecting rod is provided with a mating part, which is hinged to the hinged part.
[0010] Correspondingly, both the positioning rod and the movable rod are provided with two hinged parts, and both hinged parts are hinged to the mating part; a limit groove is also provided at the position of the hinged part near the gripping rod, and the mating part slides linearly in the limit groove.
[0011] Preferably, the mating part is a cylindrical protrusion.
[0012] Preferably, the limiting grooves on the positioning rod and the movable rod are arranged parallel to each other.
[0013] Based on the above, it is further preferred that the positioning head is arc-shaped and the movable head is circular.
[0014] Furthermore, the minimum inner diameter of the annular positioning chuck is smaller than the maximum outer diameter of the moving end of the hydraulic connector it contacts.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. This application achieves a scissor-like clamping structure by horizontally setting the positioning rod and the movable rod, and respectively providing positioning and movable clamps for contacting the fixed and movable ends of the hydraulic connector. These are hinged to each other via a connecting rod on the operating rod. This structure utilizes manual gripping to drive the two rods to close, causing the positioning and movable clamps to clamp the fixed and movable ends of the hydraulic connector, thus enabling rapid assembly and disassembly of the hydraulic connector. Compared to traditional pliers, this structure offers greater adaptability and more precise operation, avoiding connector damage caused by limited operation or uneven force, and effectively improving the maintenance efficiency and safety of the hydraulic components in cigarette packaging machines.
[0017] 2. This application sets the connecting rods as two intersecting rods that are hinged at the intersection to form a shearing part. During operation, the squeezing action of holding the rods can achieve a lever amplification effect, so that the positioning chuck and the movable chuck generate a stable and uniform clamping force, ensuring that the two ends of the hydraulic connector are released or fastened synchronously. This reduces the force required by the operator and improves the comfort of operation and the reliability of the connection.
[0018] 3. The limiting grooves on the positioning rod and the movable rod of this application cooperate with the mating part on the connecting rod, and realize linear sliding guidance during operation. This makes the movement trajectory of the operating rod stable and controlled during opening and closing, effectively avoiding the phenomenon of misalignment or jamming between the connecting rod and the positioning rod and the movable rod. This allows the positioning head and the movable head to move in parallel with each other, thereby improving the smoothness and accuracy of the tool when disassembling and assembling hydraulic joints and reducing the error rate.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0026] like Figure 1-3 As shown, in this embodiment, by horizontally setting the positioning rod 1 and the movable rod 4, and respectively setting a positioning clamp 2 and a movable clamp 5 at one end of each rod, which correspond to the fixed end 9 and the movable end 10 of the hydraulic connector 8, structural adaptation between the tool and the hydraulic connector 8 is achieved. The positioning clamp 2 contacts the fixed end 9 of the hydraulic connector 8, which plays a stabilizing and limiting role during disassembly and assembly, while the movable clamp 5 contacts the movable end 10 of the hydraulic connector 8, which is the main point of action for achieving quick disassembly or connection. By setting these two clamps on two horizontally arranged rods, the tool can exert force from the horizontal direction even when the hydraulic connector 8 is installed vertically, significantly improving the ease of operation under space-constrained or vertically arranged conditions. Therefore, the tool provided in this embodiment is particularly suitable for application scenarios with small internal space and dense wiring, such as cigarette packaging machines.
[0027] Furthermore, the introduction of the operating lever and its connection with the positioning lever 1 and the movable lever 4 via the hinge 3 constitute a linkage clamping mechanism. One end of the operating lever is a gripping lever 6, and the other end is a connecting lever 7. When the operator grips the gripping lever 6, the hinge 3 drives the connecting lever 7, thereby pushing the positioning lever 1 and the movable lever 4 to move towards or away from each other, thus clamping or releasing the hydraulic connector 8. The operating lever and hinge structure design provided in this embodiment enable the operator to achieve a greater clamping or releasing force with less external force, exhibiting good labor-saving effect and mechanical efficiency.
[0028] The two intersecting connecting rods 7 form a "scissor lever structure." When the user grips the operating rod, the two connecting rods 7 rotate in opposite directions under the constraint of the intersecting hinge point, thereby driving the positioning rod 1 and the movable rod 4 to clamp or move away from the two ends of the hydraulic connector 8, realizing the locking or releasing operation of the hydraulic connector 8. In this embodiment, the intersecting hinge point acts as a transmission pivot, providing a controllable clamping arm while realizing structural linkage. This allows the operator to obtain sufficient clamping or pulling force through mechanical amplification with only a small gripping force. This mechanical transmission advantage greatly reduces the intensity of operation, and maintains stable and efficient disassembly and assembly performance, especially when dealing with highly tightened connectors in hydraulic systems.
[0029] Compared to a linear push structure, the shearing section 11 structure has higher response accuracy and structural stability. In the cross-connection state, the two connecting rods 7 form a stable triangular structure that restrains each other, effectively preventing deflection, swaying, or loosening of the hinge 3 during the movement of the connecting rods 7, thus ensuring that the tool as a whole maintains good geometric stability during operation.
[0030] Specifically, in this embodiment, a mating part 12 is provided on the connecting rod 7, which is hinged to the two hinged parts 3 on the positioning rod 1 and the movable rod 4 respectively. This means that each connecting rod 7 is simultaneously linked with two horizontally arranged working rods at two different positions. Compared with a single-point connection, this multi-point hinged connection structure can make the pushing and pulling force during operation more evenly distributed on the entire working rod, preventing swaying, shaking, or torque deviation caused by single-point force, thereby achieving more stable and reliable opening and closing control.
[0031] Furthermore, a limiting groove 13 is provided on the hinge portion 3 near the gripping rod 6, allowing the mating portion 12 to slide linearly within the limiting groove 13. The limiting groove 13 restricts the sliding path of the mating portion 12, ensuring that it always moves along a preset linear direction, thereby ensuring that the positioning rod 1 and the movable rod 4 maintain coordinated and symmetrical movement during opening and closing. Limitation is provided when the positioning head 2 and the movable head 5 move relative to each other, ensuring that the movable head 5 always moves in a parallel horizontal displacement.
[0032] In this embodiment, as Figure 2 As shown, defining the mating part 12 as a cylindrical protrusion is a result of considerations regarding structural fit and motion characteristics. When mating with the hinge part 3 or the limiting groove 13, the cylindrical protrusion possesses good rotational symmetry and sliding stability, enabling reliable hinge functionality while allowing for low-damping linear sliding within the limiting groove 13. This reduces frictional resistance and jamming issues, ensuring a smooth sliding guide path for the connecting rod 7 during opening and closing. Compared to other shapes, the cylindrical protrusion is easier to machine, has better centering, and wider assembly tolerances, significantly improving the feasibility and consistency of tool manufacturing and assembly.
[0033] Furthermore, the limiting grooves 13 on the positioning rod 1 and the movable rod 4 are designed to be parallel to each other, so that the mating parts 12 on both sides maintain the same direction of movement and trajectory path during sliding. This parallel guiding structure can enhance the consistency and symmetry of the movement of the two mechanisms, ensuring that the positioning rod 1 and the movable rod 4 always apply force to the hydraulic connector 8 in a synchronous manner, avoiding problems such as eccentric clamping or misaligned contact during clamping, improving the overall coordination and safety of the disassembly and assembly operation of the hydraulic connector 8, and preventing damage to tools or connector components.
[0034] like Figure 1 As shown, the positioning clamp 2 is set as an arc shape and the movable clamp 5 is set as a ring shape, which is an adaptive design that takes into account both structural coverage and quick release. The arc-shaped clamp can firmly fit the outer surface of the fixed end 9 of the hydraulic connector 8, and play a role in precise positioning and force bearing, while the ring-shaped clamp has a stronger coverage capacity and can reliably fit around the outer circumference of the movable end 10, which facilitates providing complete surrounding force when pulled out.
[0035] like Figure 3 As shown, in particular, the minimum inner diameter of the annular chuck in this embodiment is smaller than the maximum outer diameter of the movable end 10 of the hydraulic connector 8, forming an active interference fit in the structural meshing, ensuring that the annular chuck can elastically clamp or press the connector when clamping, making it difficult to slip out. During operation, it can effectively transmit disassembly force, ensuring that the connector can be quickly removed in one go without repeated operation.
