Description

Technical Field

[0001] This utility model relates to the field of manual machinery and equipment technology, and in particular to a tool for connecting hoses and connectors. Background Technology

[0002] With societal development, a large number of hoses and various connectors attached to them are used in daily life. However, connecting these various hoses and connectors has become a challenge.

[0003] Currently, most installation aids for placing connectors (such as nuts) on the market are of fixed size and cannot be adjusted. However, connectors produced by different manufacturers have dimensional tolerances, lacking a unified standard. This results in some brands of nuts not fitting into the device, limiting product applicability. Furthermore, most installation aids on the market lack pipe clamping devices, only connector placement mechanisms, making installation inconvenient and prone to misalignment. Additionally, current installers lack mechanisms to assist in pushing the connector onto the pipe, requiring manual operation or the use of other auxiliary tools to install the connector.

[0004] Therefore, this utility model provides a tool for connecting hoses and connectors, which can effectively solve the above problems. Utility Model Content

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] Reference Figures 1 to 8 A tool for mating a flexible hose 1 and a connector 2, characterized in that it comprises:

[0040] Base 100, the base 100 including mounting axis α;

[0041] A hose clamping assembly 200 is slidably connected to the base 100;

[0042] A connector clamping assembly 300 is rotatably connected to the base 100;

[0043] A drive assembly 400 is used to drive the connector clamping assembly 300 so that the connector clamping assembly 300 rotates about the assembly axis α while moving closer to or away from the hose clamping assembly 200.

[0044] With the above-described structure, during use, the drive component 400 can drive the connector clamping component 300 to rotate around the assembly axis α, while simultaneously moving closer to or further away from the hose clamping component 200 along the axial direction, allowing the connector 2 to synchronously advance axially during rotation. This composite motion mode of "rotation + linear feed" significantly shortens the mating time, making it particularly suitable for rapid assembly scenarios with precision requirements, effectively improving efficiency compared to traditional manual operation. Using the assembly axis α as a reference, the rotational and linear movements of the connector clamping component 300 are precisely executed along the same axis, ensuring that the mating surfaces of the connector 2 and the hose 1 always maintain a low coaxiality error, effectively avoiding sealing failure or stress concentration problems caused by angular deviations. The sliding connection design of the hose clamping component 200 allows manual adjustment of the clamping distance and clamping force according to the thickness of the hose 1, coordinating with the rotational feed of the connector 2 to achieve uniform axial pressure loading, ensuring consistent compression at the connection end of the hose 1, improving the sealing performance and mechanical strength of the connection joint, and further enhancing the user experience.

[0045] In this embodiment, the connector clamping assembly 300 includes a clamping housing 310, the driving assembly 400 includes a driving screw 410, and the base 100 includes a base threaded hole 110. The clamping housing 310 is fixedly connected to the driving screw 410, and the driving screw 410 is rotatably connected to the base threaded hole 110. When the driving screw 410 rotates in the base threaded hole 110, the clamping housing 310 drives the connector clamping assembly 300 to rotate around the assembly axis α while moving closer to or away from the hose clamping assembly 200. With this structure, during use, when the driving screw 410 rotates clockwise, the clamping housing 310 drives the connector clamping assembly 300 to rotate around the assembly axis α while moving closer to the hose clamping assembly 200 until the hose 1 and the connector 2 are assembled. This structure achieves screw-in docking of the connector and hose 1 through threaded transmission. When the drive screw 410 rotates, it engages with the threaded hole 110 of the base, causing the clamping housing 310 fixed thereon to move along the axis and rotate synchronously, thus driving the connector 2 to complete the "rotate-and-advance" action. This design integrates linear and rotary motion into a single drive source, simplifying the mechanism; the self-locking property of the threaded pair ensures a stable connection, making it suitable for quick-connect fittings in fluid pipelines that require anti-loosening, improving assembly efficiency and reliability. It should be noted that the threaded hole 110 of the base is a through hole, and the drive screw 410 passes through the threaded hole 110 of the base before being fixedly connected to the clamping housing 310.

[0046] In this embodiment, the connector clamping assembly 300 further includes a first clamping piece 320 and a second clamping piece 330. The clamping housing 310 includes a fixed housing 311 and a movable housing 312, with the movable housing 312 lockably connected to the fixed housing 311. When the movable housing 312 is in the unlocked state, the first clamping piece 320 and the second clamping piece 330 are detachably installed on the fixed housing 311 and the movable housing 312. When the movable housing 312 is in the locked state, the first clamping piece 320 and the second clamping piece 330 are used to fix the connector 2. With the above structure, when the movable housing 312 is unlocked, the first clamping piece 320 and the second clamping piece 330 can be separated, facilitating the replacement of connectors 2 of different specifications or maintenance. When the movable housing 312 is locked, the first clamping piece 320 and the second clamping piece 330 form a circumferential structure, fixing the connector 2 by mechanical locking force. The modular design of the clamping pieces improves versatility, while the mechanical locking ensures the reliability of the connection between the connector 2 and the hose 1.

[0047] In this embodiment, the first clip 320 includes a first clip mounting portion 321, and the second clip 330 includes a second clip mounting portion 331. The fixed housing 311 is provided with a first clip mounting groove 3111, and the movable housing 312 is provided with a second clip mounting groove 3121. The first clip mounting portion 321 matches the first clip mounting groove 3111, and the second clip mounting portion 331 matches the second clip mounting groove 3121. Both the first clip mounting groove 3111 and the second clip mounting groove 3121 are provided with an adjustment device 340. The adjustment device 340 is used to adjust the position of the first clip 320 and the second clip 330 in the first clip mounting groove 3111 and the second clip mounting groove 3121. With the above-described structure, during use, the adjustment device 340 can compensate for machining errors, ensuring that the connector 2 clamped by the first clamping piece 320 and the second clamping piece 330 is aligned with the assembly axis α, thereby improving coaxiality; the first clamping piece mounting part 321 matches the first clamping piece mounting groove 3111, and the second clamping piece mounting part 331 matches the second clamping piece mounting groove 3121, ensuring circumferential positioning accuracy and preventing the clamping pieces from rotating relative to the clamping housing 310 during operation.

[0048] In this embodiment, the adjustment device 340 includes a first adjustment element 341 and a second adjustment element 342. The inner side of the first clamping piece 320 is provided with a first groove 322, and the second clamping piece 330 is provided with a second groove 332. The first groove 322 and the second groove 332 match the outer contours of opposite sides of the connector 2. With the above structure, in use, the first adjustment element 341 and the second adjustment element 342 (in this embodiment, the first adjustment element 341 and the second adjustment element 342 are both screws) can independently adjust the position of the clamping piece to compensate for machining tolerances; the matching of the first groove 322 and the second groove 332 (in this embodiment, the first groove 322 and the second groove 332 are both V-grooves) with the outer contour of the connector 2 (in this embodiment, the outer contour of the connector 2 includes a region with a hexagonal cross-section) increases the contact area and improves clamping stability.

[0049] In this embodiment, the first adjusting element 341 and the second adjusting element 342 are respectively disposed on the fixed housing 311 and the movable housing 312. When the movable housing 312 is in the locked state, the positions of the first adjusting element 341 and the second adjusting element 342 are symmetrical with respect to the assembly axis α. With the above structure, in use, the first adjusting element 341 and the second adjusting element 342 ensure the coaxiality and balanced clamping of the connector 2 through a symmetrical adjustment mechanism: after the movable housing 312 is locked, the two adjusting elements form a mirror constraint, so that the first clamping piece 320 and the second clamping piece 330 are aligned with the assembly axis α, avoiding connection defects caused by unilateral force; the symmetrically arranged first adjusting element 341 and the second adjusting element 342 generate a balanced radial force when locked, which cancels out the eccentricity error.

[0050] In this embodiment, the drive assembly 400 further includes a drive handle 420, which is movably connected to the drive screw 410 and is used to drive the drive screw 410 to rotate. With this structure, during use, the drive handle 420 is movably connected to the drive screw 410, facilitating the provision of a rotational force point, conforming to ergonomics, and reducing operator fatigue. The drive handle 420 drives the drive screw 410 to rotate within the base threaded hole 110, converting manual kinetic energy into a "rotational + linear" composite motion of the connector clamping assembly 300, thereby achieving the docking / separation of the connector 2 and the hose 1.

[0051] In this embodiment, the drive screw 410 includes a threaded drive portion 411 and a handle mounting portion 412, the handle mounting portion 412 having a handle mounting hole 4121; the drive handle 420 includes a connecting portion 421 and a gripping limiting portion 422, the gripping limiting portion 422 being located at both ends of the connecting portion 421, the connecting portion 421 being movably connected to the handle mounting hole 4121. With this structure, during use, the movable connection between the handle mounting portion 412 and the connecting portion 421 transmits the rotational motion of the drive handle 420 to the drive screw 410, enabling manual control of the docking / disengagement of the connector 2. Simultaneously, the gripping limiting portion 422 prevents the drive handle 420 from slipping during operation, improving operational safety.

[0052] In this embodiment, the hose clamping assembly 200 includes a third adjusting element 210, a first clamping element 220, and a second clamping element 230. The base 100 includes a mounting guide rail 120, which is arranged in a direction perpendicular to the assembly axis α. The first clamping element 220 and the second clamping element 230 are slidably connected to the mounting guide rail 120. The third adjusting element 210 is used to adjust the distance between the first clamping element 220 and the second clamping element 230. With the above structure, in use, the hose clamping assembly 200 provides linear guidance through the mounting guide rail 120. The third adjusting element 210 drives the first clamping element 220 and the second clamping element 230 to slide in opposite directions, achieving adaptive clamping and release of hoses 1 of different diameters, ensuring the coaxiality of the hose 1 and the connector 2.

[0053] In this embodiment, the hose clamping assembly 200 further includes a limiting element 240, which is disposed between the first clamping element 220 and the second clamping element 230. The limiting element 240 is used to restrict the movement of the third adjusting element 210 in a direction parallel to the mounting guide rail 120. With the above structure, during use, the limiting element 240 constrains the axial displacement of the third adjusting element 210, preventing it from moving along the guide rail direction. This ensures that the adjusting force only acts on the opening and closing actions of the first clamping element 220 and the second clamping element 230, avoiding uneven clamping force or hose eccentricity caused by the offset of the third adjusting element 210, thus improving clamping stability and coaxial accuracy.

[0054] In this embodiment, the first clamping element 220 includes a first threaded hole 221, the second clamping element 230 includes a second threaded hole 231, and the third adjusting element 210 includes a first threaded portion 211 and a second threaded portion 212. The first threaded portion 211 is threadedly connected to the first threaded hole 221, and the second threaded portion 212 is threadedly connected to the second threaded hole 231. The thread directions of the first threaded portion 211 and the second threaded portion 212 are opposite. With the above structure, in use, the hose clamping assembly 200 achieves synchronous alignment adjustment of the first clamping element 220 and the second clamping element 230 through reverse threads: when the third adjusting element 210 rotates, the first threaded portion 211 and the second threaded portion 212, due to their opposite rotation directions, drive the first clamping element 220 and the second clamping element 230 to move synchronously in opposite or opposite directions along the guide rail, automatically aligning the assembly axis α, ensuring that the hose 1 is always coaxial with the connector 2 when clamped, and improving the docking accuracy.

[0055] In this embodiment, the third adjusting element 210 further includes a limiting ring groove 213, which is disposed between the first threaded portion 211 and the second threaded portion 212. The limiting element 240 includes a connecting end 241 and a limiting end 242. The connecting end 241 is fixedly connected to the base 100, and the limiting end 242 matches the outer contour of a portion of the limiting ring groove 213. With the above structure, during use, the cooperation between the limiting ring groove 213 and the limiting element 240 achieves axial constraint and rotational guidance for the third adjusting element 210. The limiting end 242 is embedded in the limiting ring groove 213, allowing the third adjusting element 210 to rotate freely around its axis to drive the opening and closing of the first clamping element 220 and the second clamping element 230, while simultaneously restricting the axial movement of the third adjusting element 210, ensuring the stability of the threaded transmission, preventing axial movement during adjustment, and improving the coaxial accuracy of the hose 1 clamping.

[0056] In this embodiment, the third adjusting element 210 further includes a control handle 214, which is used to control the rotation of the third adjusting element 210, thereby controlling the first clamping element 220 and the second clamping element 230 to move closer or further apart. With this structure, during use, the control handle 214 amplifies the operating torque through a lever principle, allowing the operator to drive the first clamping element 220 and the second clamping element 230 by rotating the third adjusting element 210, achieving synchronous opening and closing of the first clamping element 220 and the second clamping element 230. This design converts rotational motion into linear displacement, facilitating manual adjustment of the jaw spacing to adapt to different specifications of hoses 1, while utilizing the self-locking characteristics of the threaded pair to maintain clamping force, improving operational convenience and clamping stability.

[0057] In this embodiment, the first clamping element 220 includes a third groove 222 that matches the outer contour of a portion of the hose 1, and the second clamping element 230 includes a fourth groove 232 that matches the outer contour of a portion of the hose 1. Both the third groove 222 and the fourth groove 232 are provided with anti-slip structures. Through the above structural design, in use, the third groove 222 and the fourth groove 232, along with the anti-slip structure, achieve stable clamping of the hose 1: the third groove 222 and the fourth groove 232 conform to the outer contour of the hose 1, providing circumferential constraint and ensuring that the axis of the hose 1 coincides with the assembly axis α; the anti-slip structure (such as serrations or a rubber layer) increases friction, preventing the hose 1 from slipping during operation and improving connection reliability.

[0058] In this embodiment, the fixed housing 311 includes a first connecting portion 3112, and the movable housing 312 includes a second connecting portion 3122. The first connecting portion 3112 and the second connecting portion 3122 are rotatably connected so that the fixed housing 311 and the movable housing 312 can rotate relative to each other. With this structure, during use, the movable housing 312 rotates relative to the fixed housing 311 to unlock / lock, facilitating quick loading / unloading of the clamping piece or replacement of the connector 2, thus improving operational efficiency. Simultaneously, the first connecting portion 3112 and the second connecting portion 3122 constrain the movement trajectory of the movable housing 312, ensuring that the clamping piece is aligned with the assembly axis α when locked, avoiding clamping failure due to misalignment. The rigid rotational connection stably transmits clamping force, forming a reliable mechanical constraint, suitable for scenarios requiring frequent disassembly and assembly.

[0059] In this embodiment, the clamping housing 310 further includes a connecting pin 313. The first connecting portion 3112 and the second connecting portion 3122 are rotatably connected via the connecting pin 313, so that the fixed housing 311 and the movable housing 312 can rotate relative to each other. With the above structure, in use, the connecting pin 313 serves as a rotation fulcrum, allowing the fixed housing 311 and the movable housing 312 to form a hinged structure.

[0060] In this embodiment, the clamping housing 310 further includes a locking shaft 314, and the movable housing 312 includes a locking groove 3123. The locking shaft 314 and the locking groove 3123 cooperate with each other to control the movable housing 312 to switch between a locked state and an unlocked state. With the above structure, in use, the clamping housing 310 realizes the rapid locking and unlocking of the first clamping element 220 and the second clamping element 230 through the cooperation of the locking shaft 314 and the locking groove 3123; when the locking shaft 314 is embedded in the locking groove 3123, it can restrict the rotational freedom of the movable housing 312, keep the movable housing 312 in a closed state, and provide a stable clamping force.

[0061] In this embodiment, the locking shaft 314 includes a locking shaft section 3141 and an unlocking shaft section 3142. The locking groove 3123 matches the outer contour of the locking shaft section 3141 to restrict the rotation of the movable housing 312 relative to the fixed housing 311, thereby locking the movable housing 312. The locking shaft 314 moves axially to match the outer contour of the locking groove 3123 with the outer contour of the unlocking shaft section 3142, thereby releasing the restriction of the locking shaft section 3141 on the rotation of the movable housing 312 relative to the fixed housing 311. With the above-described structure, during use, the locking shaft 314 achieves dual-state switching between the movable housing 312 and the fixed housing 311 through a stepped shaft design: when the locking shaft segment 3141 matches the locking groove 3123, its cylindrical profile restricts the movable housing 312 from rotating around the connecting pin 313, forming a rigid constraint to ensure stable clamping force of the first clamping element 220 and the second clamping element 230; axially moving the locking shaft 314 allows the smaller diameter unlocking shaft segment 3142 to align with the locking groove 3123, enabling the movable housing 312 to gain rotational freedom and quickly open the first clamping element 220 and the second clamping element 230; the stepped shaft segment provides clear operational feedback, avoids a semi-locked state, and provides a simple and reliable locking solution for the quick clamping mechanism.

[0062] In this embodiment, the fixed housing 311 is provided with a shaft mounting blind hole 3113 and a shaft mounting through hole 3114. The locking shaft 314 is axially movable and mounted in the shaft mounting blind hole 3113 and the shaft mounting through hole 3114. With the above structure, in use, the combination of the shaft mounting blind hole 3113 and the shaft mounting through hole 3114 provides guidance and limitation for the locking shaft 314: the coaxial design of the two holes ensures precise alignment between the locking shaft 314 and the locking groove 3123 of the movable housing 312, improving locking reliability.

[0063] In this embodiment, a spring 3115 is provided in the shaft mounting blind hole 3113. The spring 3115 abuts against the locking shaft 314 and applies a preload force to the axial direction of the locking shaft 314. With this structure, during use, the thrust of the spring 3115 ensures that the locking shaft section 3141 always matches the locking groove 3123 without external force, keeping the movable housing 312 in a locked state without additional driving force, simplifying the operation process. Simultaneously, the spring force counteracts the impact of external forces such as vibration on the locking shaft 314, preventing accidental unlocking due to axial movement and improving the reliability of the mechanism.
