Description

Technical Field

[0001] This utility model relates to the technical field of connecting buckle processing and assembly tools, and in particular to a vertical trajectory buckle clamp. Background Technology

[0002] Crimping pliers are a type of hand tool widely used in clothing, bags, webbing, and other fields to quickly and securely crimp metal or plastic fasteners onto one or more pieces of material. Their basic principle is that a pair of plier arms, connected by a hinge axis, utilize leverage to apply a small force at the handles, generating a larger crimping force at the plier heads, thus completing the fastener installation.

[0003] In existing technologies, common crimping pliers typically include an upper pressure head and a crimping seat positioned opposite each other. Traditional crimping pliers struggle to guarantee crimping accuracy. During operation, the pressure head and crimping seat are prone to relative misalignment due to uneven force or incorrect operating techniques, causing the crimp to fail to accurately engage in the preset connection position. This not only affects assembly efficiency but also reduces connection reliability. This positioning deviation problem is particularly pronounced when crimping miniaturized and precision components. Operators often require extensive experience and repeated adjustments to their operating posture to barely achieve the desired crimping effect, resulting in high operational instability and a high rate of defective products.

[0016] Both the guide rod and the upper pressure head are provided with ferromagnetic components, so that the guide rod and the upper pressure head can be magnetically and detachably connected through the ferromagnetic components.

[0017] Furthermore, it also includes an elastic reset member, one end of which abuts against the first support arm, and the other end of which abuts against the first clamp head, so that the elastic force of the elastic reset member drives the first clamp head to reset in a direction away from the snap fastener.

[0018] Furthermore, the elastic reset element is a compression spring structure, which is sleeved on the guide rod.

[0019] Furthermore, the guide rod is rotatably mounted on the first clamp head, and the guide rod is capable of sliding along the length of the first clamp arm.

The guide structure of the first support arm cooperates with the guide rod of the first clamping arm to forcibly constrain the upper pressure head connected to the guide rod to move closer to or further away from the crimping seat connected to the second support arm along a fixed direction. This effectively avoids relative displacement between the pressure head and the crimping seat during the crimping process, significantly improving crimping accuracy. Furthermore, the design of the guide structure and support arm makes force transmission more stable, reducing crimping force fluctuations caused by operational deviations. Combined with the reliable support of the support arm for the crimping components, it reduces the risk of crimping movement and avoids connection failures and component damage caused by excessively loose or tight crimping. At the same time, it retains the compact and flexible operating advantages of traditional crimping pliers, achieving precise and stable crimping without relying on extensive operator experience, thus improving operational efficiency and connection quality consistency.

[0043] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Please refer to the following: Figures 1 to 6 This embodiment provides a vertical trajectory snap clamp, including a first clamp arm 100 and a second clamp arm 200. The first clamp arm 100 has a first clamp head 110, a first clamp handle 120 and a first hinge position 130. The second clamp arm 200 has a second clamp head 210, a second clamp handle 220 and a second hinge position 230. The first hinge position 130 and the second hinge position 230 are rotatably connected. The second clamp head 210 is forked to form a first support arm 211 and a second support arm 212. The first support arm 211 is located between the first clamp head 110 and the second support arm 212. A guide structure is provided on the first support arm 211. A guide rod is provided on the first clamp arm 100. The guide rod can move towards or away from the second support arm 212 under the guidance of the guide structure. The side of the guide rod facing the second support arm 212 is used to connect to the upper pressure head, and the side of the second support arm 212 facing the first support arm 211 is used to connect to the snap clamp seat.

[0045] As can be seen, the vertical trajectory crimping pliers of this embodiment form a basic operating structure through the hinged connection of the first clamping arm 100 and the second clamping arm 200. At the same time, a stable support frame is constructed by the first support arm 211 and the second support arm 212 formed by the forking of the second clamping head 210. The guide structure of the first support arm 211 cooperates with the guide rod of the first clamping arm 100 to forcibly constrain the upper pressure head connected to the guide rod to move closer to or away from the crimping seat connected to the second support arm 212 along a fixed direction. This effectively avoids the relative displacement between the pressure head and the crimping seat during the crimping process, significantly improving the crimping accuracy. Moreover, the design of the guide structure and the support arm makes the force transmission more stable, reducing the fluctuation of crimping force caused by the deviation of the operation technique. With the reliable support of the support arm for the crimping components, the risk of crimping movement is reduced, avoiding connection failure and component damage caused by crimping that is too loose or too tight. At the same time, it retains the compact and flexible operation advantages of traditional crimping pliers, achieving accurate and stable crimping without relying on the operator's rich experience, improving operation efficiency and connection quality consistency.

[0046] In this embodiment, as Figures 1 to 6As shown, the second support arm 212 and the snap fastener are detachably connected. Specifically, the second support arm 212 has a first receiving groove 214 on the side facing the first support arm 211. A limiting fastener is installed in the first receiving groove 214, and a limiting rod is provided on the snap fastener. The limiting rod is pluggably installed in the limiting fastener, so that the second support arm 212 and the snap fastener are detachably connected. The limiting fastener has a receiving groove 410, and part of the inner wall of the receiving groove 410 protrudes radially inward to form a locking protrusion 420, thereby forming a limiting wall structure on the inner wall of the receiving groove 410. Preferably, the snap fastener is made of plastic. This allows the snap fastener pliers improved in this embodiment to complete pressing, forming, and punching according to different molds. Applicable to buttons, eyelet belts, etc.

[0047] The first receiving groove 214 allows for quick assembly and disassembly of the limiting fastener and the limiting rod of the snap fastener seat through pluggable engagement, facilitating the replacement of the snap fastener seat with a suitable one according to different snap fastener specifications, thus improving tool compatibility and versatility. The locking protrusion 420 on the inner wall of the receiving groove 410 of the limiting fastener forms a limiting wall structure, which can reliably limit the inserted limiting rod, preventing the snap fastener seat from loosening or falling off due to force during the pressing operation, and ensuring pressing stability and accuracy. The snap fastener seat is preferably made of plastic, which not only reduces the weight of the component and manufacturing cost, but also reduces the hard impact on the snap fastener or the part to be connected during pressing by utilizing the cushioning properties of plastic, reducing the risk of surface damage. At the same time, plastic material is easy to process and mold, making it easy to adapt to different limiting rod structure requirements.

[0048] In one possible implementation, the second support arm 212 has a first receiving groove 214 on the side facing the first support arm 211. The inner wall of the first receiving groove 214 is provided with an internal thread structure, and the snap fastener is provided with an external thread structure, so that the second support arm 212 and the snap fastener can be detachably connected.

[0049] The internal thread on the inner wall of the first receiving groove 214 engages with the external thread of the snap fastener, enabling a detachable connection between the two. This facilitates quick replacement of snap fasteners with compatible ones according to different specifications, significantly improving the tool's adaptability and versatility for diverse pressing needs. The threaded connection features self-locking and tightness, providing stable support for the snap fastener during pressing operations. This effectively prevents the snap fastener from loosening or shifting under pressing force, ensuring pressing position accuracy and connection reliability. Furthermore, the threaded connection structure is mature and easy to manufacture. Assembly only requires rotation to complete the fixation, making disassembly convenient and efficient. This reduces operational difficulty and also minimizes wear and tear during component assembly and disassembly, extending the tool's service life.

[0050] In another possible implementation, both the second support arm 212 and the snap fastener are provided with ferromagnetic elements to magnetically and detachably connect the second support arm 212 and the snap fastener via the ferromagnetic elements.

[0051] The ferromagnetic components are magnets, and the magnetic attraction between them allows for quick and direct attraction, fixation, and separation without complex insertion, removal, or rotation operations. This greatly simplifies the assembly and disassembly process of the snap-fit ​​base, improves efficiency when changing snap-fit ​​bases of different specifications, and adapts to the rapid switching needs in batch operation scenarios.

[0052] In this embodiment, the upper pressure head and the guide rod are detachably connected. Specifically, a second receiving groove is provided on the side of the guide rod facing the second support arm 212, and a limiting fastener is installed in the second receiving groove. A limiting rod is provided on the upper pressure head, and the upper pressure head is pluggably installed in the limiting fastener so that the upper pressure head and the guide rod are detachably connected.

[0053] The tool features a pluggable connection between the limiting fastener in the second receiving slot of the guide rod and the upper pressure head limiting rod, enabling quick assembly and disassembly. This facilitates the replacement of the upper pressure head with a suitable one according to different pressing specifications or pressing requirements, significantly improving the tool's adaptability and versatility for various pressing scenarios. The limiting fastener provides reliable limiting constraint on the inserted limiting rod, preventing the upper pressure head from loosening, shifting, or even falling off due to force on the mandrel during pressing operations, thus ensuring the stability and positioning accuracy of the pressing process. Furthermore, the pluggable connection method is convenient to operate, allowing for the replacement of the upper pressure head without the need for additional tools, reducing operational difficulty, improving work efficiency, and offering a simple and easy-to-manufacture structure that reduces component manufacturing costs and assembly losses.

[0054] In one possible implementation, a second receiving groove is provided on the side of the guide rod facing the second support arm 212. The inner wall of the second receiving groove is provided with an internal thread structure, and the upper pressure head is provided with an external thread structure, so that the upper pressure head and the guide rod can be detachably connected. The threaded connection has excellent self-locking and tight connection, which can provide a stable installation base for the upper pressure head during the pressing operation, effectively preventing the upper pressure head from loosening or shifting due to force, and ensuring the consistency of pressing position accuracy and pressing quality.

[0055] In another possible implementation, both the guide rod and the upper pressure head are provided with ferromagnetic components, which allow the guide rod and the upper pressure head to be magnetically and detachably connected. The ferromagnetic components are magnets, and the magnetic attraction between the ferromagnetic components can directly achieve rapid adsorption, fixation, and separation of the two without the need for complex mechanical connection operations. This greatly simplifies the disassembly and assembly process of the upper pressure head, and facilitates the rapid replacement of the appropriate upper pressure head according to different buckle specifications or pressing requirements. This significantly improves the tool's adaptability and switching efficiency for various pressing scenarios.

[0056] Preferably, such as Figures 1 to 3As shown, it also includes an elastic reset member 500. One end of the elastic reset member 500 abuts against the first support arm 211, and the other end of the elastic reset member 500 abuts against the first clamp head 110, so that the elastic force of the elastic reset member 500 drives the first clamp head 110 to reset in a direction away from the pressure seat. Preferably, the elastic reset member 500 is a compression spring structure, and the compression spring structure is sleeved on the guide rod.

[0057] In this design, an elastic reset element 500 is installed between the first support arm 211 and the first clamp head 110. The elastic force of the elastic reset element 500 drives the upper pressure head to reset away from the clamp seat, eliminating the need for manual reset of the upper pressure head. This simplifies the operation, improves the continuity and efficiency of the clamping operation, and ensures that the upper pressure head returns to its original position promptly after each pressing, preventing wear caused by continuous contact between the upper pressure head and the clamp seat. The use of a compression spring structure as the elastic reset element 500 provides stable reset performance and controllable elastic force, reliably driving the upper pressure head to accurately reset away from the clamp seat, preventing the upper pressure head from jamming after clamping and affecting subsequent operations. Furthermore, the compression spring structure is fitted onto the upper pressure head, eliminating the need for additional installation structures, simplifying the overall structural design and assembly process of the clamping pliers. The coaxial arrangement of the spring and the upper pressure head ensures that the reset force is evenly applied to the upper pressure head, improving the stability and consistency of the reset, and further guaranteeing the continuity and efficiency of the clamping operation.

[0058] In this embodiment, as Figures 1 to 6 As shown, the guide rod is rotatably mounted on the first jaw 110, and the guide rod can slide along the length direction of the first jaw arm 100. The guide structure is a guide groove 213 structure, which is perpendicular to the length direction of the second support arm 212, so as to form a first opening 213a and a second opening 213b at both ends of the second support arm 212, respectively. The first opening 213a is corresponding to the first jaw 110, and the second opening 213b is corresponding to the second support arm 212. The guide rod includes a guide rod body 310 and a rotating shaft 320. The rotating shaft 320 is disposed on the guide rod body 310. The first jaw 110 is provided with a sliding groove 111, which is arranged along the length direction of the first jaw arm 100, so that the guide rod body 310 can be rotatably mounted on the first jaw 110 by inserting the rotating shaft 320 into the sliding groove 111, and the rotating shaft 320 can slide along the length direction of the sliding groove 111.

[0059] The guide rod, through the cooperation of the rotating shaft 320 and the sliding groove 111 of the first clamp head 110, realizes rotation around the rotating shaft 320 and sliding along the length direction of the first clamp arm 100. At the same time, in conjunction with the guide groove 213 set perpendicular to the length direction of the second support arm 212, the guide rod body 310 can move stably along the guide groove 213. It can adapt to the position changes when the first clamp arm 100 and the second clamp arm 200 are hinged and rotated, ensuring that the upper pressure head always accurately approaches or moves away from the pressure seat along the direction of the guide groove 213, avoiding pressing offset and improving pressing accuracy. The sliding cooperation between the sliding groove 111 and the rotating shaft 320 and the rotation design of the guide rod can buffer the force transmission deviation during the operation of the two clamp arms, reduce the hard friction between the guide structure and the guide rod, and reduce component wear. The first opening 213a and the second opening 213b of the guide groove 213 provide a clear guide path for the movement of the guide rod. With the double limit of the rotating shaft 320 and the sliding groove 111, the stability of the guide rod movement during the pressing process is further guaranteed, improving the overall operational reliability and tool life.

[0060] Preferably, the first clamp arm 100 or the second clamp arm 200 includes a pivot 600 to rotatably connect the first hinge position 130 and the second hinge position 230. The pivot 600, as a mature rotational connection structure, can provide stable and smooth rotational support for the first clamp arm 100 or the second clamp arm 200.

[0061] Preferably, the plane containing the first clamp arm 100 coincides with the plane containing the second clamp arm 200. This arrangement ensures that the force transmission of the first clamp arm 100 and the second clamp arm 200 is within the same plane, avoiding lateral force components caused by plane misalignment. This ensures precise alignment of the upper pressure head and the pressure seat during pressing, reducing the risk of misalignment and improving pressing accuracy. Simultaneously, the planar design allows for smoother force application by the operator, higher force transmission efficiency, reduced physical exertion during operation, and improved ease of use. Furthermore, the planar overlap structure is more compact, facilitating tool storage and carrying, and reducing frictional wear between components caused by planar misalignment during use, thus extending the tool's lifespan.

[0062] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0063] The basic operating structure is formed by the hinged engagement of the first clamp arm 100 and the second clamp arm 200. Simultaneously, a stable support frame is constructed using the forked first support arm 211 and the second support arm 212 formed by the second clamp head 210. The guide structure of the first support arm 211 cooperates with the guide rod of the first clamp arm 100, which can forcibly constrain the upper pressure head connected to the guide rod to move closer to or further away from the snap fastener connected to the second support arm 212 along a fixed direction. This effectively avoids relative misalignment between the pressure head and the snap fastener during the pressing process, significantly improving the pressing accuracy. Furthermore, the design of the guide structure and support arm makes the force transmission more stable, reducing fluctuations in pressing force caused by operational errors. Combined with the reliable support of the support arm for the pressing components, this reduces the risk of snap fastener movement and avoids connection failures and component damage caused by excessively loose or tight pressing. At the same time, it retains the compact and flexible operating advantages of traditional snap fasteners, achieving precise and stable pressing without relying on extensive operator experience, thus improving operational efficiency and connection quality consistency.
