Description

Technical Field

[0001] This utility model relates to the field of multifunctional emergency tools, and in particular to a magnetic attraction nail safety hammer. Background Technology

[0002] Safety hammers in the current technology are mainly used in vehicle emergency scenarios, such as breaking windows for escape and cutting seat belts. Their structure usually includes a handle and a sharp window-breaking component, which achieves the function through simple impact. However, as users' demand for the multi-functionality of tools increases, some safety hammers have begun to integrate auxiliary components such as nail removal and cutting to expand their application range.

[0003] Among these multi-functional safety hammers, nailing is a common need, which often relies on the hammer head to directly strike the nail. However, traditional hammer heads lack a dedicated fixing mechanism, which causes the nail to easily slip or deflect during the hammering process, affecting accuracy and efficiency. Especially in narrow spaces or emergency situations, this instability will amplify the difficulty of operation.

[0004] Furthermore, while existing magnetic hammerheads attempt to introduce magnetic adsorption, the fit between the magnet's position and the nail-accommodating structure is often inaccurate. For example, if the magnetic force direction is not vertically aligned or the shape of the receiving groove is not suitable, the adsorption force may be weak or the nail may shift, making it difficult to achieve stable nail driving and thus limiting the overall practicality of the safety hammer.

[0005] Therefore, this utility model proposes a magnetic attraction nail safety hammer to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing magnetic attraction nail safety hammer, such as the imprecise matching between the magnet position and the nail receiving structure, which leads to weak attraction force or nail displacement, this utility model aims to provide a magnetic attraction nail safety hammer with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a magnetic attraction nail safety hammer, including: a safety hammer handle, a replacement head shell, a window breaker nail, a magnetic hammer head, and a ring buckle; as well as a pliers handle, a connecting shaft, an M-shaped tail buckle, a rotating shaft, wire cutters, and pliers.

[0008] The magnetic hammer head has a groove at the end and a magnet is fixedly connected to the bottom of the groove. The central axis of the groove coincides with the axis of the magnetic hammer head to ensure adsorption alignment. The ring buckle has a structure in which the inner wall and the outer wall of the magnetic hammer head can be detachably engaged. The pliers handle has a layout in which the end is connected to the M-shaped tail buckle through the connecting shaft and the middle is connected to the mounting hole on the side of the safety hammer handle through the rotating shaft. The wire cutters and pliers have the feature that the cutting edge plane and the clamping plane are parallel to each other and are both parallel to the axial direction of the connecting shaft.

[0009] Furthermore, the safety hammer handle, replacement head housing, and magnetic hammer head are combined in a manner where the replacement head housing is fixedly connected to the inside of the safety hammer handle, and the magnetic hammer head is detachably housed within the replacement head housing. A ring-shaped buckle connects the safety hammer handle and magnetic hammer head to the top of the safety hammer handle via a rotating connection, with the inner wall of the ring-shaped buckle detachably engaging with the outer wall of the magnetic hammer head. A pliers handle, safety hammer handle, and rotating shaft are combined in a manner where the pliers handle is symmetrically rotated to the safety hammer handle, and the middle part is rotatably connected to the side mounting hole via the rotating shaft. Wire cutters and pliers are fixedly connected to the top of the safety hammer handle via the wire cutters and pliers. The magnetic hammer head, wire cutters, and safety hammer handle are combined in a manner where the hammering surface of the magnetic hammer head and the cutting edge of the wire cutters are located at the same axial end of the safety hammer handle. These combinations ensure a compact overall structure and coordinated functions, avoiding the problems of unstable adsorption and inconvenient replacement in traditional designs, thus improving operational reliability and multi-functional integration.

[0010] Preferably, the groove structure has a conical blind hole design with an opening diameter larger than the bottom diameter to form a telescopic guide, which facilitates nail embedding and enhances self-locking stability, further improving adsorption accuracy and hammering efficiency.

[0011] Preferably, the engaging surface of the annular buckle and the engaging surface of the magnetic hammer head have matching limiting protrusions and limiting grooves. The limiting protrusions protrude from the inner wall of the annular buckle, while the limiting grooves are opened on the outer wall of the magnetic hammer head to achieve an embedded fit, thus avoiding the risk of falling off due to vibration.

[0012] Preferably, the inner wall contour of the replacement head housing has a clearance fit with the outer contour of the window breaker nail and the magnetic hammer head, and the inner wall forms an arc cavity to restrict radial movement, ensuring compact storage and easy and quick removal for replacement.

[0013] Preferably, the magnetic nail-pulling safety hammer also includes a claw nail puller and a blade. The claw nail puller is fixedly connected to the side of the safety hammer handle and the nail-pulling end has a wedge-shaped double-fork structure with a fork angle of 30°. The blade is retractably embedded in a sliding groove on the side of the safety hammer handle to assist in nail prying and cutting operations, further expanding the application scenarios of the tool.

[0014] Preferably, the magnet is made of permanent magnet and its magnetization direction is perpendicular to the bottom surface of the groove to generate a directional magnetic field, ensuring strong adsorption and durability.

[0015] Preferably, the gripping section of the pliers handle has a textured surface with anti-slip patterns. The patterns form a cross-grip to increase the coefficient of friction, thereby improving stability and comfort when gripping.

[0016] Preferably, the connection between the pliers handle and the M-type tail buckle is that the M-type tail buckle has an arc-shaped groove at the engaging end that matches the diameter of the connecting shaft. The pliers are rotated and engaged with the connecting shaft through the arc-shaped groove to optimize torque transmission and reduce wear.

[0017] This utility model has the following beneficial effects: This invention solves the problems of unstable nail adsorption and positioning misalignment in the prior art by fixing a magnet to the bottom of a groove at the end of a magnetic hammer head, with the central axis of the groove coinciding with the axis of the hammer head. This achieves the technical effect of stable nail adsorption and precise centering.

[0018] This invention solves the problem of loose and easy-to-fall-off replacement head in the prior art by using a technical solution that allows the inner wall of the annular buckle to be detachably fastened to the outer wall of the magnetic hammer head and is equipped with mutually matching limiting protrusions and limiting grooves. This achieves the technical effect of stable hammer head installation and vibration resistance. Attached Figure Description

[0022] Please refer to Figures 1 to 4This utility model provides a magnetically attracted nail safety hammer, which aims to solve the problems of unstable magnetic nailing components and loose replacement heads when multiple functions are integrated in the existing safety hammer.

[0023] like Figure 1 and Figure 2As shown, the magnetic attraction nail safety hammer includes a safety hammer handle 1 and a replacement head shell 2 fixedly connected inside the safety hammer handle 1. The safety hammer handle 1 serves as the gripping base and mounting base of the entire device, while the replacement head shell 2 serves as a storage cavity to accommodate replacement parts. A ring-shaped buckle 7 is rotatably connected to the top of the safety hammer handle 1. The inner wall of the ring-shaped buckle 7 and the outer wall of the magnetic attraction hammer head 9 are matched by limiting protrusions and limiting grooves to achieve a detachable locking connection. Two symmetrically rotatably connected clamp handles 5 are externally connected to the safety hammer handle 1. The ends of the clamp handles 5 are rotatably connected to an M-shaped tail buckle 6 via a connecting shaft 10. The M-shaped tail buckle 6 has an arc-shaped groove at its engaging end that matches the diameter of the connecting shaft 10 to ensure a stable fit of the rotatable connection. The handle 5 is rotatably connected to the mounting hole on the side of the safety hammer handle 1 via a pivot 11. A wire cutter 12 and a vise 13 are fixedly connected to the top of the safety hammer handle 1. The cutting edge of the wire cutter 12 and the clamping surface of the vise 13 are parallel to each other and both parallel to the axial direction of the connecting shaft 10 for linkage force transmission. The hammering surface of the magnetic hammer head 9 and the cutting edge of the wire cutter 12 are located at the same axial end of the safety hammer handle 1 to form an integrated layout. A groove 14 is provided at the end of the magnetic hammer head 9, and a magnet 15 is fixedly connected to the bottom of the groove 14. The central axis of the groove 14 coincides with the axis of the magnetic hammer head 9 to ensure adsorption and alignment. The magnet 15, as a permanent magnet, has its magnetization direction perpendicular to the bottom surface of the groove 14 to maximize the adsorption force. The groove 14 has a conical blind hole structure. To facilitate nail embedding and positioning, the inner contour of the replacement head housing 2 is fitted with the outer contour of the window breaker nail 8 and the magnetic hammer head 9 to achieve compact accommodation. A claw nail puller 3 is fixedly connected to the side of the safety hammer handle 1. The claw nail puller 3 has a wedge-shaped double-forked structure with a fork angle of 30° to facilitate prying and applying force. A sliding groove is also provided on the side of the safety hammer handle 1, and the blade 4 can be retractably embedded in the sliding groove for sliding connection and storage. The grip section of the pliers 5 has anti-slip texture to enhance grip stability. These components form an organic whole through the above connection relationship. The replacement head housing 2 fixedly connected inside the safety hammer handle 1 and the annular buckle 7 rotatably connected to the top work together to support quick replacement head switching. The pliers 5 and the rotating shaft 11 The rotating connecting chain of the connecting shaft 10 drives the opening and closing of the wire cutters 12 and the pliers 13. The positional relationship between the groove 14 of the magnetic hammer head 9 and the magnet 15 ensures axial alignment when the nail is attracted, preventing displacement. The matching engagement of the limiting protrusion of the ring buckle 7 with the limiting groove of the magnetic hammer head 9 further fixes the position of the hammer head to prevent it from falling off. The wedge-shaped double fork of the horn nail puller 3 provides a lever fulcrum by being fixedly connected to the side of the handle. The sliding connection of the blade 4 in the groove allows it to extend for cutting or retract for concealment to improve safety. The arc groove of the M-shaped tail buckle 6 cooperates with the rotation of the connecting shaft 10 to optimize torque transmission and reduce wear. In the entire structure, the safety hammer handle 1 serves as the central hub, integrating the fixed and rotating connections of all components to achieve multi-functional synergy.

[0024] To solve the aforementioned technical problems, the core of the technical solution in this embodiment lies in the fact that the magnetic attraction nail safety hammer also includes a magnetic hammer head 9, and that the magnetic hammer head 9 forms a specific structural fit and connection relationship with the aforementioned safety hammer handle 1 and replacement head shell 2. The technical solution or technical feature needs to be described in detail and expressed logically clearly. It is not acceptable to briefly describe or omit technical features to avoid insufficient disclosure during patent examination. Please refer to the following carefully. Figure 3 and Figure 4 The core structure will be described in detail below: The magnetic hammer head 9 has a groove 14 at its end, and a magnet 15 is fixedly connected to the bottom of the groove 14 by embedding. The central axis of the groove 14 coincides with the axis of the magnetic hammer head 9 to achieve adsorption alignment. The magnetization direction of the magnet 15 is perpendicular to the bottom surface of the groove 14 to generate a vertical adsorption force. The groove 14 adopts a conical blind hole structure with a smooth transition of its inner wall to guide the nail to be inserted. The outer wall of the magnetic hammer head 9 has an annular limiting groove, which matches the limiting protrusion on the inner wall of the annular buckle 7 to form a snap-fit ​​connection. The entire magnetic hammer head 9 is accommodated inside the replacement head housing 2 through a clearance fit. The inner wall contour of the replacement head housing 2 fits tightly with the outer contour of the magnetic hammer head 9 to limit lateral displacement. The hammering surface of the magnetic hammer head 9 is located at the axial end of the safety hammer handle 1 and is aligned with the wire cutter. The 12 blade edges are aligned on the same side for integrated operation. Their function is to provide stable adsorption and positioning for the nail and transmit hammering force. Magnet 15 is a permanent magnet with a rust-proof coating to enhance durability. Simultaneously, an outlet channel is provided at the corresponding position on the replacement head housing 2. This channel is parallel to the axis of the magnetic hammer head 9 for easy insertion and removal. The annular buckle 7 is fixed to the top of the safety hammer handle 1 via a rotatable connection. Its rotation axis is perpendicular to the length direction of the safety hammer handle 1 to allow for flipping and locking. The height of the limiting protrusion on the inner wall of the annular buckle 7 is equal to the depth of the limiting groove of the magnetic hammer head 9 to achieve a gapless lock-on. In the assembled state, the limiting groove on the outer wall of the magnetic hammer head 9 engages with the limiting protrusion of the annular buckle 7. This locking structure of the limiting protrusion and the limiting groove ensures the magnetic hammer head... 9. High stability and anti-detachment capability during hammering: The inner wall of the groove 14 at the end of the magnetic hammer head 9 is glued to the outer edge of the magnet 15 to prevent separation. The tapered angle of the groove 14 gradually decreases from the opening to the bottom for self-locking of the nail. The window-breaking nail 8 is also accommodated in the adjacent chamber of the replacement head housing 2 with a clearance fit, its tip facing the axial end of the safety hammer handle 1 for replacement. The rotatable connection between the pliers handle 5 and the safety hammer handle 1 is achieved through a rotating shaft 11. This rotating shaft 11 passes through the middle hole of the pliers handle 5 and is fixed to the side mounting hole of the safety hammer handle 1 to form symmetrical swing. The connecting shaft 10 passes through the end of the pliers handle 5 and is embedded in the arc-shaped groove of the M-shaped tail buckle 6 to complete the rotatable connection. The curvature of the arc-shaped groove of the M-shaped tail buckle 6 matches the diameter of the connecting shaft 10 to reduce friction. The cutting edge of the wire cutter 12 is welded to the top of the safety hammer handle 1, with its cutting edge plane parallel to the axial direction of the connecting shaft 10 to transmit the torque of the handle 5. The clamping plane of the pliers 13 is also welded to the top of the safety hammer handle 1 and arranged parallel to the wire cutter 12 for coordinated clamping. The wedge-shaped double fork of the nail puller 3 is integrally formed and fixed to the side of the safety hammer handle 1, with a fork angle of 30° to optimize the prying power arm. The cutting edge of the blade 4 is slidably embedded in the slide groove on the side of the safety hammer handle 1. The depth of the slide groove matches the thickness of the blade 4 to allow for telescopic movement. The anti-slip texture of the grip section of the handle 5 is integrally formed by embossing to increase friction. All these connections ensure the stable integration of the magnetic hammer head 9 with the overall frame.

[0025] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to enhance the self-locking stability when the nail is inserted, the groove 14 adopts a conical blind hole structure with an opening diameter larger than the bottom diameter to form a telescopic guide. The inner wall of the groove 14 is precision machined to form a smooth surface to reduce insertion resistance. The bottom of the groove 14 is fixedly connected to the magnet 15 by insertion to ensure that the magnetic force is directly transmitted to the nail head. The depth of the groove 14 matches the length of the standard iron nail head to fully accommodate it. The side wall of the groove 14 is inclined at an angle of 15 degrees to optimize the adsorption and retention force.

[0026] As a preferred embodiment, to enhance the vibration resistance during locking, please refer to... Figure 4 The annular buckle 7 and the magnetic hammer head 9 have matching limiting protrusions and limiting grooves. The limiting protrusion is integrally formed and protrudes from the inner wall of the annular buckle 7 with a height of 2 mm. The limiting groove is milled and opened on the outer wall of the magnetic hammer head 9. Its depth is equal to the height of the limiting protrusion to achieve an embedded fit. The cross-section of the limiting protrusion is rectangular to prevent rotation and loosening. The gap between the width of the limiting groove and the width of the limiting protrusion is 0.1 mm to ensure a tight connection. The annular buckle 7 is fixed to the top of the safety hammer handle 1 by a rotatable connection. Its rotation axis is perpendicular to the axis of the safety hammer handle 1 to allow for flipping operation.

[0027] As a preferred embodiment, in order to improve the compactness and anti-fall-off performance when storing the replacement head, the inner wall contour of the replacement head shell 2 is fitted with the outer contour of the window breaker nail 8 and the magnetic hammer head 9 with a clearance fit. The inner wall of the replacement head shell 2 is formed into an arc cavity by injection molding, the radius of which matches the diameter of the magnetic hammer head 9 to limit radial movement. The outer contour of the window breaker nail 8 is machined into a cone shape by lathe, with its tip facing the outlet of the replacement head shell 2 for easy removal. The clearance fit size is controlled within 0.2 mm to avoid shaking. The replacement head shell 2 is fixedly connected to the inside of the safety hammer handle 1, and its cavity axis is parallel to the length direction of the safety hammer handle 1 to align the replacement path.

[0028] As a preferred implementation method, to optimize the layout and security of the auxiliary tools, please refer to... Figure 3The safety hammer handle 1 has a nail puller 3 fixedly connected to its side and a blade 4 retractably embedded in a groove on the side of the safety hammer handle 1. The nail puller 3 has a wedge-shaped double-fork structure with a fork angle of 30° to provide a balanced prying force arm. The ends of the double forks are ground to form sharp edges to embed under the nail. The nail puller 3 is fixedly connected to the side of the safety hammer handle 1 by welding and is positioned close to the middle of the handle for applying force. The blade 4 is slidably embedded in the groove, which is a rectangular groove whose depth matches the thickness of the blade 4 to allow for forward and backward extension. The blade 4 is heat-treated to harden its cutting edge, and its cutting edge direction is parallel to the length direction of the safety hammer handle 1 for cutting operations. The inner wall of the groove is provided with a positioning spring to fix the blade 4 in the extended or retracted position.

[0029] In a preferred embodiment, to improve magnetic attraction strength and durability, magnet 15 is a permanent magnet with its magnetization direction perpendicular to the bottom surface of groove 14 to generate a directional magnetic field. Magnet 15 is pressed and fixedly connected to the bottom of groove 14, and its outer edge is tightly fitted with the groove wall to prevent displacement. The surface of magnet 15 is plated with a nickel layer with a thickness of 0.05 mm to prevent corrosion. The diameter of magnet 15 is equal to the diameter of the bottom of groove 14 to cover the entire adsorption area. The magnetic force of magnet 15 is N45 to attract standard iron nails.

[0030] As a preferred embodiment, in order to enhance the anti-slip effect when gripping, the gripping section of the pliers handle 5 is provided with anti-slip texture. The texture is formed by knurling to form a cross grid with a grid spacing of 1 mm to increase the coefficient of friction. The gripping section of the pliers handle 5 is integrally formed and connected to the pliers handle body. The surface texture depth is 0.5 mm to avoid hand discomfort. The middle part of the pliers handle 5 is rotatably connected to the mounting hole on the side of the safety hammer handle 1 through the pivot 11 to realize swing operation.

[0031] As a preferred embodiment, to improve the smoothness and wear resistance of the rotating connection, please refer to... Figure 3 The M-type tail buckle 6 has an arc-shaped groove at its engaging end that matches the diameter of the connecting shaft 10. This arc-shaped groove is formed by stamping, and its radius of curvature is equal to that of the connecting shaft 10 to achieve a close rotation. The inner surface of the arc-shaped groove is polished to reduce friction. The connecting shaft 10 passes through the end of the clamp handle 5 and is embedded in the arc-shaped groove to complete the rotational connection. The depth of the arc-shaped groove is half the diameter of the connecting shaft 10 to prevent axial dislodgement. The M-type tail buckle 6 is formed by casting, and its engaging end is symmetrically arranged with the end of the clamp handle 5 to balance the force distribution.

[0032] Working principle: When the safety hammer handle 1 is held and the magnetic hammer head 9 is installed, the outer wall of the magnetic hammer head 9 is fixed to the top of the safety hammer handle 1 by engaging with the inner wall of the annular buckle 7 through the limiting groove. The annular buckle 7 is rotated to the locked position to prevent the hammer head from falling off. The head of the nail is placed into the groove 14 at the end of the magnetic hammer head 9. The conical blind hole structure of the groove 14 guides the nail to be embedded and the magnet 15 fixed at the bottom generates an attraction force in the perpendicular magnetization direction to fix the nail. The magnet 15 ensures strong attraction to prevent the nail from shifting. The safety hammer handle 1, as the holding base, transmits the user's hammering force to the magnetic hammer head 9 to complete the nailing operation. The hammering surface of the magnetic hammer head 9 and the cutting edge of the wire cutter 12 are located at the same axial end for easy function switching.

[0033] When cutting or clamping is required, hold the grip section of the pliers handle 5 with both hands. The anti-slip texture on the surface of this section increases friction and stabilizes the grip. The middle of the pliers handle 5 is rotatably connected to the mounting hole on the side of the safety hammer handle 1 via the pivot 11 to form a lever swing. The end of the pliers handle 5 is rotatably connected to the M-shaped tail buckle 6 via the connecting shaft 10. The arc groove at the snapping end of the M-shaped tail buckle 6 matches the diameter of the connecting shaft 10 and rotates to transmit torque. When the pliers handle 5 is squeezed, the pivot 11 and the connecting shaft 10 drive the wire cutter 12 fixedly connected to the top of the safety hammer handle 1 to close the blade to cut the wire. The blade plane of the wire cutter 12 is parallel to the axial direction of the connecting shaft 10 to optimize force transmission. At the same time, the clamping plane of the pliers 13 is arranged in parallel and closes in the same linkage to clamp the object.

[0034] When performing nail pulling or cutting auxiliary operations, the nail puller 3 has a wedge-shaped double fork structure at the nail pulling end that is fixedly connected to the side of the safety hammer handle 1. Its fork angle is 30° to provide a prying arm. The double fork is inserted under the nail and the safety hammer handle 1 is used as a fulcrum to pry out the nail. The blade 4 is embedded in the slide groove on the side of the safety hammer handle 1 through a sliding connection and extends out to cut the material. The depth of the slide groove matches the thickness of the blade 4 to ensure smooth extension and retraction and avoid accidental contact.

[0035] When switching to the window breaking function, the ring buckle 7 rotates to unlock the magnetic hammer head 9, and the window breaking nail 8 is taken out from the replacement head housing 2. The housing is fixedly connected to the inside of the safety hammer handle 1, and its inner wall contour fits tightly with the outer contour of the window breaking nail 8. The window breaking nail 8 is installed in the ring buckle 7 and locked in place. Holding the safety hammer handle 1, the tip of the window breaking nail 8 impacts the glass to break the window. All components work together through fixed connection, rotation connection and sliding connection to ensure stable multi-function switching.

[0036] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope.
