Description

Technical Field

[0001] This utility model relates to the field of electromagnetic nail gun technology, specifically a portable electromagnetic nail gun. Background Technology

[0002] Portable electromagnetic nail guns are handheld power tools that use electromagnetic force to drive nails. Their working principle is to discharge power to a coil to form an instantaneous magnetic field that drives the nails to be launched. They are characterized by good portability, simple operation, low noise, energy saving and environmental protection, and strong driving force. They are widely used in woodworking furniture making and installation, ceiling and wall fixing in building decoration, and wooden box sealing in the packaging industry.

[0003] To enhance magnetic conductivity, some existing portable electromagnetic nail guns use high-purity ferromagnetic materials or have thickened designs for their magnetic sleeves. However, because all-iron magnetic sleeves have a higher density, they increase the overall weight of the tool, which contradicts the requirement for "portability." This can easily lead to fatigue, especially during prolonged handheld operation. The higher price of all-iron magnetic sleeves also increases costs. Furthermore, because of their iron-based magnetic conductivity, all-iron magnetic sleeves can cause magnetic field leakage, interfering with surrounding electronic components and reducing the lifespan of the equipment. Therefore, we propose a portable electromagnetic nail gun. Utility Model Content

[0004] The purpose of this utility model is to provide a portable electromagnetic nail gun to solve the problems mentioned in the background art, which are that the magnetic sleeves are made of high-purity ferromagnetic materials or have a thickened design. Because the density of the all-iron magnetic sleeve is relatively large, it will increase the overall weight of the tool, which contradicts the requirement of "portability". In particular, it is easy to cause fatigue when holding the hand for a long time. The price of the all-iron magnetic sleeve is also high, which will increase the cost. Moreover, because the all-iron magnetic sleeve is ferromagnetic, it will cause the magnetic field to leak out, which will interfere with the surrounding electronic components and reduce the service life of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable electromagnetic nail gun, comprising: an electromagnetic nail gun body, an internal placement component, a coil inside the placement component, an iron core inside the coil, a buffer component between the iron core and the placement component, the buffer component being used to reduce the impact force generated when the iron core moves, and a trigger component fixedly connected to one end of the iron core, the trigger component being used to trigger the nail gun to work.

[0006] The placement component includes a magnetic sleeve, which is made of a composite material consisting of an aluminum layer and an iron layer, with the outer layer being an aluminum layer and the inner layer being an iron layer.

[0007] The buffer assembly includes a buffer block with a spring on it, the spring being located inside the magnetic sleeve, and a retaining ring at one end of the buffer block being located outside the magnetic sleeve.

[0008] The triggering component includes a connecting rod that is fixedly connected to the iron core. A rotating rod is fixedly connected to one side of the connecting rod. A lever is rotatably connected to the rotating rod. A rotating rod is rotatably connected to one end of the lever. The rotating rod is fixedly connected to the magnetic sleeve.

[0009] The magnetic sleeve has a groove, a fixed rod is fixedly connected in the groove, a return spring is fixedly connected on the fixed rod, and the other end of the return spring is fixedly connected to one end of the lever.

[0010] The bottom of the buffer block is circular, matching the iron core.

[0011] Among them, the rotating rod 2 is equipped with a shim.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, this utility model reduces weight and improves portability and lowers costs by designing the magnetic sleeve as a composite material. It also confines the magnetic field to reduce leakage and avoid interference with surrounding electronic components. By setting a buffer block in the buffer assembly in cooperation with the spring, the impact force of the iron core movement can be absorbed, reducing vibration and noise. The retaining ring design facilitates the disassembly and maintenance of the buffer block. At the same time, the placement component, coil, iron core and trigger component work together to convert electrical energy into a firing action. Combined with the reset spring, the trigger component can be automatically reset to ensure continuous and efficient operation. The overall design has significant improvements in terms of lightweight, electromagnetic efficiency, durability, user experience and maintenance convenience. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a portable electromagnetic nail gun, comprising: an electromagnetic nail gun body 1, a placement component 2 inside the electromagnetic nail gun body 1, a coil 3 inside the placement component 2, an iron core 4 inside the coil 3, and a buffer component 5 between the iron core 4 and the placement component 2. The buffer component 5 is used to reduce the impact force generated when the iron core 4 moves. A trigger component 6 is fixedly connected to one end of the iron core 4. The trigger component 6 is used to trigger the nail gun to work. In use, by energizing the coil 3 to generate a magnetic field, the iron core 4 moves under the action of the magnetic field, thereby driving the trigger component 6 to move, converting the movement of the iron core 4 into the firing action of the nail gun. The buffer component 5 is used to buffer the impact force generated by the iron core 4 during firing, which can effectively reduce the vibration and noise of the nail gun during operation and extend the service life of the nail gun.

[0023] The placement component 2 includes a magnetic sleeve 21. The magnetic sleeve 21 is made of composite material and consists of an aluminum layer 22 and an iron layer 23. The outer side is the aluminum layer 22 and the inner side is the iron layer 23. The use of composite materials helps to reduce the weight of the magnetic sleeve 21, greatly improves the portability of the equipment, and also reduces production costs. In addition, the outer aluminum layer 22 is designed so that the magnetic field can be confined to the inside of the iron layer 23 because aluminum does not have magnetic properties, reducing magnetic field leakage and avoiding interference to surrounding electronic components.

[0024] The buffer assembly 5 includes a buffer block 51, on which a spring 52 is provided. The spring 52 is located inside the magnetic sleeve 21. One end of the buffer block 51 is provided with a retaining ring 53, which is located outside the magnetic sleeve 21. The buffer block 51 is made of elastic rubber material, which has a good buffering and energy absorption effect. The spring 52 can provide elastic buffering force when the iron core 4 moves. The retaining ring 53 is used to fix the buffer block 51 to prevent it from shifting during operation. Furthermore, by setting the retaining ring 53 to cooperate with the magnetic sleeve 21, the buffer block 51 can be quickly installed and removed, which is convenient for maintenance and replacement.

[0025] The trigger assembly 6 includes a connecting rod 61 fixedly connected to the iron core 4. A rotating rod 62 is fixedly connected to one side of the connecting rod 61. A lever 63 is rotatably connected to the rotating rod 62. A rotating rod 64 is rotatably connected to one end of the lever 63. The rotating rod 64 is fixedly connected to the magnetic sleeve 21. When in use, pulling the trigger energizes the coil 3 to generate a magnetic field. Because the magnetic field has an attractive force, the iron core 4 moves under the action of the magnetic field, which drives the connecting rod 61 to move forward. This causes the lever 63 to move in the same direction with the rotating rod 64 as the fulcrum, so that the other end of the lever 63 strikes the nail forward, making the nail go out smoothly. Through the principle of the lever 63, the small-amplitude movement of the iron core 4 is amplified and transformed into a highly efficient trigger for the nail gun.

[0026] The magnetic sleeve 21 has a groove 7, and a fixing rod 8 is fixedly connected in the groove 7. A return spring 9 is fixedly connected to the fixing rod 8. The other end of the return spring 9 is fixedly connected to one end of the lever 63. The groove 7 is used to install the fixing rod 8 and the return spring 9, providing them with installation space. After the nail gun completes one firing action, the return spring 9 can provide a restoring force to reset the lever 63 and the trigger component 6, preparing for the next firing and ensuring the continuous and stable operation of the nail gun.

[0027] The bottom of the buffer block 51 is round, matching the iron core 4. This design ensures that the buffer block 51 is in close contact with the iron core 4, effectively dispersing the impact force generated when the iron core 4 moves, providing uniform and stable buffering force during the movement of the iron core 4, and improving the buffering effect.

[0028] Example 2

[0029] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the rotating rod 64 is provided with a shim 10. The shim 10 is made of wear-resistant material, which can reduce the friction and wear between the rotating rod 64 and the lever 63, and improve the reliability, flexibility and service life of the trigger assembly 6.
