Modes for Carrying Out the Invention
[0016] The following clearly and completely describes the technical solutions of the present invention, including the figures based on the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention and do not cover all embodiments. Based on the embodiments of the present invention, all other embodiments that can be obtained by those of ordinary skill in the art without creative labor are also included in the protection scope of the present invention.
[0017] Please refer to Embodiment 1. Shown in FIGS. 1-11 is a quick removal device. This device includes a device body 1 and a rotating tray 2 provided at the bottom of the device body 1. The rotating tray 2 is used to connect to a terminal holder. Also, inside the device body 1, a rotating latch 12 extending to the bottom and fixedly connected to the rotating tray 2 is provided. The device body 1 can rotate 360 degrees with respect to the rotating latch 12 and the rotating tray 2.
[0018] Inside the device body 1, there are two symmetrically arranged lock buckle bars 13, and two shaft levers 14 are commonly arranged inside the two lock buckle bars 13. Lock buckles 1 1301 are installed on the opposite surfaces of the two lock buckle bars 13, and lock buckles 2 1302 are installed on the upper parts of the lock buckle bars 13. A lock spring 1401 arranged between the two lock buckle bars 13 is mounted on the shaft lever 14.
[0019] Inside the device body 1, a lever 1 15 extending from the side surface of one lock buckle bar 13 and a lever 2 16 extending from the side surface of the other lock buckle bar 13 are installed. The lever 2 16 extends onto the lever 1 15 to the end away from the lock buckle bar 13, and the lever 1 15 extends to the outside of the device body 1 to the end away from the lock buckle bar 13.
[0020] Inside the device body 1, a reset switch 17 is installed between two lock buckle bars 13. On the upper part of the reset switch 17, a button 1701 extending outside the device body 1 and position slots 1702 arranged on both sides of the button 1701 are provided. The two lock buckles 1301 are respectively fitted into the two position slots 1702. During actual use, a magnet can be attached to the upper part of the device body 1 to magnetically adsorb it to the external case of the product, making the process of triggering the button 1701 more flexible.
[0021] As a specific technical solution of this embodiment, the lever 115 is composed of an operation lever 1501, a drive lever 1502 arranged at one end of the operation lever 1501, and a lever body 11503. The lever body 11503 is rotatably installed inside the device body 1 via a rotating shaft 11504. Also, the lever 216 is composed of a lever body 21601 and a transmission lever 1602 arranged at one end of the lever body 21601. The lever body 21601 is rotatably installed inside the device body 1 via a rotating shaft 21603. One ends of the lever body 11503 and the lever body 21601 extend to the opposite sides of the two lock buckle bars 13 respectively. Please refer to FIGS. 7 - 9. When the user operates the operation lever 1501, the operation lever 1501 rotates the lever body 11503, and the end of the lever body 11503 contacts the lock buckle bar 13. At the same time, the drive lever 1502 moves together with the operation lever 1501 and contacts the transmission lever 1602. The transmission lever 1602 rotates the lever body 21601, and the end of the lever body 21601 contacts the other lock buckle bar 13. Therefore, when the operation lever 1501 is operated, the lever body 11503 and the lever body 21601 can simultaneously move the two lock buckle bars 13 relatively. This structure is simple, ingenious, and flexible in operation.
[0022] As a specific technical solution of this embodiment, for the driving lever 1502, the end away from the operating lever 1501 extends to one side of a shaft lever 14, and for the transmission lever 1602, the end away from the lever body 2 1601 extends to one side of the driving lever 1502. A reset spring 1605 is installed on one side of the transmission lever 1602 via a spring post 1604. For the operating lever 1501, the end away from the driving lever 1502 extends to the outside of the device body 1. The transmission lever 1602 is compressed by the operation of the driving lever 1502 and pushed by the reset spring 1605. Due to the installation of the reset spring 1605, when the transmission lever 1602 is no longer affected by the operating force of the driving lever 1502, the reset spring 1605 rebounds and the transmission lever 1602 is quickly reset. When the transmission lever 1602 is reset, the lever body 1 1503 and the lever body 2 1601 release contact with the two lock buckle levers 13, and the two lock buckle levers 13 move relatively and slide on the shaft lever 14. At the same time, the two lock buckle levers 13 compress the lock spring 1401. Due to the installation of the lock spring 1401, when the lock buckle 1 1301 releases engagement with the position slot 1702, the lock spring 1401 rebounds and the two lock buckle levers 13 are reset.
[0023] As a specific technical solution of this embodiment, a fixed detent bolt 201 is provided at the bottom of the rotating tray 2, and a fixing hole 202 arranged inside the fixed detent bolt 201 is provided. On the upper part of the rotating tray 2, a ball groove 203 formed by a plurality of annular combinations is provided. At the bottom of the device body 1, a spring ball 11 with one end extending into the ball groove 203 is fitted. The number of the spring balls 11 is one or more, and at the bottom of the rotating latch 12, a lock body 1201 formed by a plurality of annular combinations is provided. The lock body 1201 engages with the bottom of the bottom cover 101. At the bottom of the rotating latch 12, a tap nut 1202 arranged coaxially with the fixing hole 202 is provided. The rotating latch 12 is circular, and a plurality of trays 1203 are arranged around it. The bottom of the tray 1203 is slidably connected to the upper part of the bottom cover 101. The fixed detent bolt 201 is used to connect to a terminal holder. The terminal holder includes a bicycle holder, a vehicle-mounted holder, a camera holder, and holders for other sports and electronic devices. During use, the bolt is passed through the fixing hole 202 and screwed into the tap nut 1202 to fix the rotating tray 2 and the rotating latch 12. Then, the fixed detent bolt 201 is used to connect the rotating tray 2 and the terminal holder. When the device body 1 is rotated, the spring ball 11 contacts the ball groove 203, and the ball groove is compressed. As the device body 1 rotates, it contacts different ball grooves 203. Thereby, 360-degree rotation and positioning of the device body 1 are realized. Please refer to FIG. 4. There are four spring balls 11, which ensures the stability of the relative position between the device body 1 and the rotating tray 2, preventing the device body 1 from rotating unrestrictedly under the influence of external forces.
[0024] As a specific technical solution of this embodiment, guide slopes 1703 are symmetrically arranged at both upper ends of the reset switch 17. The two guide slopes 1703 are respectively arranged on one side of the two position slots 1702. At the bottom of the reset switch 17, a switch spring 1704 that contacts the upper part of the rotary latch 12 is fitted. Please refer to FIGS. 8 and 9. Due to the installation of the guide slope 1703, when the lock buckle 1 1301 is not engaged with the position slot 1702, when the operation lever 1501 is moved, the lever body 1 1503 and the lever body 2 1601 cause relative movement with the two lock buckle bars 13. When the two lock buckle bars 13 move relatively, the lock buckle bar 13 compresses the lock spring 1401, and at the same time the lock buckle 1 1301 contacts the guide slope 1703. Due to the inclined surface design of the guide slope 1703, the contact between the lock buckle 1 1301 and the guide slope 1703 is smooth and no jamming occurs. When the guide slope 1703 is contacted, it descends and compresses the switch spring 1704. At the same time, the button 1701 retracts inward from the bottom of the device body 1. When the lock buckle 1 1301 moves further and faces the position slot 1702, the switch spring 1704 rebounds and the reset switch 17 rises, and the position slot 1702 and the lock buckle 1 1301 are engaged, and the lock buckle 1 1301 is fixed. When the user releases the operation lever 1501, the reset spring 1605 resets the operation lever 1501, and the lock buckle 1 1301 is fixed by the reset switch 17, so the lock buckle bar 13 holds its position without rotating due to the rebound of the lock spring 1401. However, the lock spring 1401 continues to rebound against the lock buckle bar 13 and connects the protrusion rest 18 and the lock buckle 2 1302 to the external case of the product. The external case of the product is a mobile phone case with slots, a tablet case, etc., and the lock buckle 2 1302 coincides with the protrusion rest 18. Since the lock buckle 1 1301 is fixed by the reset switch 17, the lock buckle 2 1302 is hidden inside the storage groove 1801.When the protrusion rest 18 is attached to the external case of the product, the protrusion rest 18 fits into the interior of the product, and at the same time, the button 1701 touches the external case of the product to lower the reset switch 17. When the reset switch 17 is lowered, the position slot 1702 releases the engagement with the lock buckle 1 1301, and the lock spring 1401 abuts against the two lock buckle bars 13 and separates from each other. When the lock buckle bar 13 is reset, at the same time, the lock buckle 2 1302 fits into the external case of the product from the inside of the storage groove 1801, and the device body 1 is connected to the external case of the product. Also, by using the button 1701 to trigger the lock buckle 2 1302, the connection process to the external case of the product can be performed more easily and quickly.
[0025] As a specific technical solution of this embodiment, the device body 1 is circular and composed of a bottom cover 101 and an upper case 102 disposed above the bottom cover 101. A lever groove 1021 for fitting with an operation lever 1501 is provided on the outer periphery of the upper case 102. A push button 1011 with one end fitted into the inside of the lever groove 1021 is disposed on the outer periphery of the bottom cover 101. A card slot 1022 with one end engaged with a reset spring 1605 is provided on the inner periphery of the upper case 102. A non-slip pad 1023 is fitted on the upper part of the upper case 102. Inside the upper case 102, positioning pins 1024 with one end extending into the inside of a reset switch 17 and a number of one or more are disposed. A screw pin 1025 is provided inside the upper case 102, and a screw hole 1012 coaxially disposed is provided inside the bottom cover 101. The number of the screw pin 1025 and the screw hole 1012 is one or more. Please refer to FIG. 1. The device body 1 is circular, has a beautiful appearance, the lever groove 1021 is in a waist shape and conforms to the operating range of the operation lever 1501. The push button 1011 fits into the lever groove 1021. By installing the positioning pins 1024, the stability of the reset switch 17 when rising and falling is ensured. When attaching the upper case 102 to the bottom cover 101, the upper case 102 and the bottom cover 101 can be fixed by passing a bolt through the screw hole 1012 and attaching it to the screw pin 1025.
[0026] As a specific technical solution of this embodiment, a protruding rest 18 is provided on the upper part of the upper case 102, and two storage grooves 1801 are symmetrically arranged at both ends of the protruding rest 18. The end of the lock buckle 2 1302 away from the lock buckle bar 13 extends into the storage groove 1801. A lock buckle display mark 19 located on one side of the protruding rest 18 is engraved on the upper part of the upper case 102. By observing the lock buckle display mark 19 and moving the operation lever 1501, the user can complete the locking and unlocking operations of the lock buckle 2 1302 and the external case of the product. Also, since the operation lever 1501 can be operated with one hand only, the operation process becomes smoother.
[0027] As a specific technical solution of this embodiment, a reinforcing rib 1303 fixedly connected to one side of the lock buckle 2 1302 is provided on the upper part of the lock buckle 1 1301. A bearing 1026 fitted to the end of the shaft lever 14 is arranged inside the upper case 102. Circlips 1402 are attached to both ends of the shaft lever 14. By installing the reinforcing rib 1303, the structural strength of the lock buckle 1 1301 and the lock buckle 2 1302 is ensured, and the bearing 1026 supports the end of the shaft lever 14 to ensure the stability of the shaft lever 14.
[0028] In Example 2, please refer to FIGS. 12-13. This includes a transmitting end positioning neodymium magnet 3, an external product case tray 4, and a receiving end positioning neodymium magnet 41 (corresponding to the wireless charging function). The transmitting end positioning neodymium magnet 3 is mounted inside the upper case 102, and the external product case tray 4 is mounted on the external case of the product. The external product case tray 4 is provided with a slot corresponding to the lock buckle 21302. The receiving end positioning neodymium magnet 41 is mounted inside the external product case tray 4. Four neodymium magnet protrusions 5 are provided on each of the transmitting end positioning neodymium magnet 3 and the receiving end positioning neodymium magnet 41. The four neodymium magnet protrusions 5 of the transmitting end positioning neodymium magnet 3 are arranged such that their polarities match those of the four neodymium magnet protrusions 5 of the receiving end positioning neodymium magnet 41. When assembling the upper case 102 and the external product case tray 4, the transmitting end positioning neodymium magnet 3 automatically rotates the upper case 102 and adjusts the coupling position between the protrusion rest 18 and the external product case tray 4. As a result, the assembly process is carried out quickly.
[0029] In use, the upper case 102 and the bottom cover 101 are fixed by passing a bolt through the screw hole 1012 and attaching it to the screw pin 1025. Next, the rotating tray 2 and the rotating latch 12 are fixed by passing a bolt through the fixing hole 202 and attaching it inside the tap nut 1202. Finally, the fixing deadbolt 201 is used to connect the rotating tray 2 and the terminal holder. When the device body 1 is rotated, the spring ball 11 contacts the ball groove 203, the ball groove is compressed, and as the device body 1 rotates, it contacts a different ball groove 203. This realizes 360-degree rotation and positioning of the device body 1. At this time, the lock buckle 1 1301 is engaged with the reset switch 17. In this state, the external case of the product can be connected. When the protrusion rest 18 and the lock buckle 2 1302 are connected to the external case of the product, the protrusion rest 18 fits into the internal case of the product, and at the same time, the button 1701 touches the external case of the product to lower the reset switch 17. When the reset switch 17 is lowered, the position slot 1702 releases the engagement with the lock buckle 1 1301, and the lock spring 1401 hits the two lock buckle bars 13 to separate them from each other. At the same time that the lock buckle bars 13 are reset, the lock buckle 2 1302 fits into the outer case of the product from inside the storage groove 1801, and the device main body 1 and the outer case of the product are connected.
[0030] When removing the external case of the product, the user holds the external case of the product with one hand and moves the operating lever 1501 with a finger referring to the lock buckle display mark 19, so that the lever body 1 1503 rotates and the end of the lever body 1 1503 contacts the lock buckle bar 13. At the same time, the drive lever 1502 moves together with the operating lever 1501 and contacts the transmission lever 1602. The transmission lever 1602 rotates the lever body 2 1601, and the end of the lever body 2 1601 contacts another lock buckle bar 13. Thus, when the operating lever 1501 is moved, the lever body 1 1503 and the lever body 2 1601 can relatively move the two lock buckle bars 13 at the same time. The transmission lever 1602 is compressed by the movement of the drive lever 1502. When the two lock buckle bars 13 relatively move, the lock spring 1401 is compressed. At the same time, the lock buckle bar 13 separates the lock buckle 2 1302 from the external case of the product. Thereby, the external case of the product and the device body 1 are separated.
[0031] When the external case of the product is separated from the device body 1, the button 1701 loses contact with the external case of the product, the switch spring 1704 rebounds and the reset switch 17 rises. Due to the rise of the reset switch 17, the position slot 1702 engages with the lock buckle 1 1301, and the lock buckle 1 1301 is positioned. Thereby, the lock buckle 2 1302 maintains the connection with the external case of the product, which is convenient for the next use.
[0032] Based on the above, this quick removal device can rotate and position the device body 1 360 degrees via the spring ball 11, meeting the user's usage needs. Also, when removing the external case of the product, it can be easily done by simply holding the external case of the product with one hand and moving the operation lever 1501. The operation is simple and the convenience of outdoor sports activities is improved. Additionally, by using the automatic trigger-type button 1701 to control the lock buckle 2 1302 and the external case of the product, the assembly process of the external case of the product is further simplified. The lock spring 1401 continuously abuts against the lock buckle bar 13, ensuring the stability of the connection between the lock buckle 2 1302 and the external case of the product, and improving the stability during the use of the product.
