Description

Technical Field

[0001] This utility model relates to the field of fastening and connection technology, and in particular to a magnetic fastener for quick assembly and disassembly of electronic devices. Background Technology

[0002] Magnetic technology, as an emerging connection technology, has been increasingly widely used in the field of electronic devices in recent years. Compared with traditional connection methods, magnetic connections have many significant advantages. The connection and disassembly process is extremely convenient; simply bringing magnetic components close or far apart easily achieves connection and separation without the need for any tools, greatly saving operation time and labor costs.

[0003] While existing electronic device fasteners use magnetic attraction for fastening, this method only involves fixing magnets and iron plates to the surfaces of two sets of devices to be locked, and then using the magnetic attraction to fix the electronic devices. When there is shaking, it may cause slight misalignment of the two sets of device surfaces, which will eventually cause the two sets of devices to separate.

[0004] Therefore, it is necessary to provide a magnetic quick-release fastener for electronic devices to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a magnetic quick-release fastener for electronic devices, which solves the problem that when there is shaking, the surfaces of the two sets of devices may move slightly out of alignment, eventually causing the two sets of devices to separate.

[0006] To solve the above-mentioned technical problems, the magnetic quick-release fastener for electronic devices provided by this utility model includes: an electronic device, wherein the electronic device is equipped with a fastening component, and a limiting component for restricting the movement of the fastening component is installed between the fastening component and the electronic device, wherein the fastening component is used to restrict the opening and closing of the electronic device.

[0007] Preferably, the electronic device includes a bottom shell and a top shell. The top of the bottom shell and the bottom of the top shell are evenly provided with a plurality of arc-shaped grooves. The top of the top shell is provided with four sets of circular grooves II evenly provided. Each set of circular grooves II is provided with a circular groove I at the top. A circular groove III is provided at the center of the top of the top shell. A rectangular groove is provided between the circular groove III and the four sets of circular grooves I. The rectangular groove, circular groove I, circular groove II, circular groove III and the top of the bottom shell are connected to a fastening assembly.

[0008] Preferably, the fastening assembly includes iron bars and round blocks. Four sets of iron bars are evenly fixedly installed at four corners on the top of the bottom shell. The top of each set of iron bars is connected to the limiting assembly. Four sets of strip rods are evenly fixedly installed on the outer wall of the round block. A magnet is fixedly installed at the other end of each set of strip rods. A handle is fixedly installed on the top of the round block.

[0009] Preferably, the limiting component includes grooves, and four sets of grooves are evenly opened on the top of four sets of iron bars, with a limiting block rotatably connected to the inner wall of each set of grooves.

[0010] Preferably, the inner wall of each of the two circular grooves is coated with a shielding layer, which is a thick permalloy shielding layer.

[0011] Preferably, several sets of buffer pads are evenly installed on the top of the bottom shell outside the iron rod and on the outside of the circular groove at the bottom of the top shell. The buffer pads are made of rubber.

[0012] Compared with related technologies, the magnetic quick-release fastener for electronic devices provided by this utility model has the following advantages:

[0013] This utility model provides a magnetic quick-release fastener for electronic devices. The circular groove on the top shell is connected to the iron rod on the top of the bottom shell. Then, by holding the handle, the circular block drives four sets of bar rods, causing four sets of annular magnets to be inserted into the circular groove. The magnets are magnetically connected to the iron rod, thus restricting the bottom shell and the top shell. When disassembly is required, simply hold the handle and pull out the magnets. Through the interaction of the above components, the left-right and up-down movement of the bottom shell and the top shell can be effectively prevented.

[0014] When the top of the iron rod penetrates the top of the circular groove, the limiting block is flipped over so that its bottom is in contact with the top of the top shell and the top of the magnet block respectively, thereby restricting the upward movement of the magnet block and further reinforcing the mutual locking between the bottom shell and the top shell.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the magnetic quick-release fastener for electronic devices provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the internal structure of the circular groove shown; Figure 3 for Figure 1 The diagram shows the structure of the iron rod. Figure 4 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 5 for Figure 2 The enlarged schematic diagram of part B is shown. The magnetic quick-release fastener for electronic devices includes: an electronic device 1, wherein the electronic device 1 is equipped with a fastening component 2, and a limiting component 3 is installed between the fastening component 2 and the electronic device 1 to restrict the movement of the fastening component 2. The fastening component 2 is used to restrict the opening and closing of the electronic device 1.

[0023] The electronic device 1 includes a bottom shell 11 and a top shell 12. Several sets of arc-shaped grooves 13 are evenly formed on the top of the bottom shell 11 and the bottom of the top shell 12. Circular grooves 16 are evenly formed at the four corners of the top of the top shell 12. Circular grooves 14 are formed on the top of each set of circular grooves 16. Circular grooves 17 are formed at the center of the top of the top shell 12. Rectangular grooves 15 are formed between the circular grooves 17 and the four sets of circular grooves 14. The rectangular grooves 15, circular grooves 14, circular grooves 16, circular grooves 17 and the top of the bottom shell 11 are connected to the fastening assembly 2.

[0024] After aligning the arc-shaped grooves 13 on the bottom shell 11 and the top shell 12, the fastening components 2 are inserted sequentially into the rectangular groove 15, the first circular groove 14, the second circular groove 16, and the third circular groove 17.

[0025] The fastening assembly 2 includes iron rods 21 and round blocks 23. Four sets of iron rods 21 are evenly fixedly installed at four corners on the top of the bottom shell 11. The top of each set of iron rods 21 is connected to the limiting assembly 3. Four sets of strip rods 24 are evenly fixedly installed on the outer wall of the round blocks 23. A magnet block 22 is fixedly installed at the other end of each set of strip rods 24. The magnet block 22 is ring-shaped. A handle 25 is fixedly installed on the top of the round blocks 23.

[0026] Connect the circular groove 16 on the top shell 12 to the iron rod 21 on the top of the bottom shell 11. Then, hold the handle 25 and drive the four sets of bar rods 24 through the circular block 23, so that the four sets of annular magnet blocks 22 are inserted into the circular groove 14, and the magnet blocks 22 are magnetically connected to the iron rod 21, thereby restricting the bottom shell 11 and the top shell 12.

[0027] The limiting component 3 includes a groove 31. Four sets of grooves 31 are evenly opened on the top of four sets of iron rods 21. The grooves 31 penetrate the side wall of the iron rods 21. Each set of grooves 31 has a limiting block 32 rotatably connected to the inner wall of the inner wall.

[0028] The friction between the limiting block 32 and the inner wall of the groove 31 is relatively large, so the limiting block 32 will not rotate easily. When the top of the iron rod 21 penetrates the top of the circular groove 16, the limiting block 32 is flipped so that its bottom is in contact with the top of the top shell 12 and the top of the magnet block 22 respectively, thereby restricting the upward movement of the magnet block 22.

[0029] Each of the circular grooves 16 has a shielding layer 5 on its inner wall. The shielding layer 5 is a thick permalloy shielding layer. By coating the inner wall of the circular groove 16 with a thick permalloy shielding layer 5, the leakage of magnetic field can be prevented.

[0030] Several sets of buffer pads 4 are evenly installed on the top of the bottom shell 11 outside the iron rod 21 and on the outside of the circular groove 16 at the bottom of the top shell 12. The buffer pads 4 are made of rubber and can reduce the damage caused by compression when the bottom shell 11 and the top shell 12 are connected.

[0031] The working principle of the magnetic quick-release fastener for electronic devices provided by this utility model is as follows: After the electronic device 1 to be repaired is repaired, the electronic device 1 is assembled and restrained by the fastening component 2. Then, the fastening component 2 is locked by the limiting component 3 to further strengthen the restraint of the electronic device 1. At the same time, the above process can be reversed to quickly disassemble the electronic device 1.

[0032] Compared with related technologies, the magnetic quick-release fastener for electronic devices provided by this utility model has the following advantages:

[0033] Connect the circular groove 16 on the top shell 12 to the iron rod 21 on the top of the bottom shell 11. Then, hold the handle 25 and drive the four sets of bar rods 24 through the circular block 23, so that the four sets of annular magnet blocks 22 are inserted into the circular groove 14. The magnet blocks 22 are magnetically connected to the iron rod 21, thereby restricting the bottom shell 11 and the top shell 12. When disassembly is required, simply hold the handle 25 and pull out the magnet blocks 22. Through the interaction of the above components, the bottom shell 11 and the top shell 12 can be effectively prevented from moving left and right or up and down.

[0034] When the top of the iron rod 21 penetrates the top of the circular groove 16, the limiting block 32 is flipped so that its bottom is in contact with the top of the top shell 12 and the top of the magnet block 22 respectively, thereby restricting the upward movement of the magnet block 22 and further reinforcing the mutual locking between the bottom shell 11 and the top shell 12.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
