[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] Please see Figure 1-4As shown, a martial arts performance prop includes two sticks 1, a connecting ring 101, and a metal chain 102. Each stick 1 has a threaded hole at one end, and a connecting post 2 is threadedly connected to the inner cavity of the threaded hole. Two rotating plates 201 are symmetrically arranged radially in the inner cavity of the connecting post 2. The rotating plates 201 are rotatably connected to the connecting post 2 via pins. A locking block 202 is fixedly connected to one side of each rotating plate 201. An annular groove 203 matching the locking block 202 is opened on the inner wall of the threaded hole. A return spring 204 is provided between each rotating plate 201 and the connecting post 2. One end of the return spring 204 abuts against the rotating plate 201, and the other end is fixed to the inner wall of the connecting post 2. Two clearance grooves 205 are opened at one end of the connecting post 2. The free end of the rotating plate 201 extends into the clearance groove 205 and slides with the clearance groove 205. A rectangular groove 206 is opened on the top of each rotating plate 201.
[0022] Through the threaded connection between the threaded hole and the connecting column 2, combined with the cooperation of the locking block 202 and the annular groove 203 of the rotating plate 201, the quick assembly and disassembly of the rod body and the connecting column can be realized. The threaded connection provides initial positioning, and the structure of the locking block 201 and the annular groove 203 prevents axial loosening, thus meeting the requirements of "detachable storage and quick assembly" for performance props.
[0023] The reset spring 204 keeps the rotating plate 201 in the state where the locking block 202 is embedded in the annular slot 203, thus avoiding connection failure due to vibration or collision during the performance and improving structural reliability.
[0024] The clearance groove 205 provides guidance for the sliding of the rotating plate 201, and the rectangular groove 206 provides a force application point for tools (such as pliers), making it easy for users to drive the rotating plate 201 to rotate with external tools, thereby unlocking the locking block 201 (compressing the return spring 204 causes the locking block 201 to disengage from the annular locking groove 203), simplifying the maintenance and disassembly process.
[0025] Each rod body 1 has a battery 3 fixedly installed in its inner cavity. An LED light ring 301 is embedded in the circumferential direction on the surface of the rod body 1. The LED light ring 301 is electrically connected to the battery 3. The other end of the rod body 1 is provided with a charging interface 302 and a sliding switch 303. The charging interface 302 is electrically connected to the battery 3, and the sliding switch 303 is connected in series between the battery 3 and the LED light ring 301.
[0026] The LED light ring 301 provides surround lighting, which can enhance the visual impact in martial arts performances through flashing and color changing, making it especially suitable for nighttime or stage performances.
[0027] The built-in battery 3 supports operation without an external power source. The charging port 302 and the sliding switch 303 enable complete circuit control of "charging-switching-lighting", enhancing the independence and ease of use of the prop.
[0028] The charging port 302 is a Type-C interface, and the battery (3) is a rechargeable lithium battery with a capacity of 1000-2000mAh, supporting 5V / 1A fast charging;
[0029] Each rod body 1 is covered with four equidistant anti-slip sleeves 4. The anti-slip sleeves 4 are located between adjacent LED light rings 301. The anti-slip sleeves 4 are foam anti-slip sleeves. The anti-slip sleeves 4 are fixedly connected to the rod body 1 by strong adhesive, and the two ends of the anti-slip sleeves 4 are chamfered.
[0030] The foam material provides a soft, non-slip feel, reducing hand fatigue during prolonged holding; four equidistant anti-slip sleeves adapt to different grip postures and prevent the stick from slipping during high-speed swinging.
[0031] The chamfer fits snugly against the surface of the rod body 1 to prevent the edge of the anti-slip sleeve 4 from lifting up;
[0032] The anti-slip sleeve 4 is located between the LED light rings 301 to avoid obstructing the light display, thus balancing functionality and aesthetics.
[0033] The connecting ring 101 is fixedly connected to the end of the connecting post 2 away from the rod body 1. The metal chain 102 is a stainless steel chain, and its two ends are respectively sleeved in the inner cavity of the two connecting rings 101.
[0034] The inner wall of the rectangular groove 206 is provided with anti-slip texture, which is a cross-grid structure.
[0035] The cross-grid anti-slip texture increases the friction between the tool and the inner wall of the rectangular groove 206, preventing the tool from slipping when inserted. This improves operational stability, especially when precise force is required (such as fine-tuning the angle of the rotating plate), and avoids structural damage caused by tool slippage.
[0036] LED light ring 301 is an RGB full-color light ring, and the sliding switch 303 has three adjustment positions;
[0037] The RGB full-color light ring supports multiple color changes and has three adjustable levels (off, single color constant light, multi-color gradient flashing) to meet the lighting needs of different performance scenarios (such as single color atmosphere, dynamic effects) and improve the applicability of the prop.
[0038] When it is necessary to replace rod body 1, the specific operating procedure is as follows:
[0039] Disassembly steps
[0040] Unlocking the locking structure: Take a tool such as pliers or a special wrench and insert both ends of the tool into the rectangular grooves 206 on the top of the two rotating plates 201 respectively (the cross-grid anti-slip texture on the inner wall of the rectangular groove 206 can increase the friction between the tool and the groove wall and prevent slippage).
[0041] Compression of the return spring: The operating tool applies force inward, driving the two rotating plates 201 to rotate around the center of the connecting column 2 (the free end of the rotating plate slides along the relief groove 205). At this time, the rotating plate 201 squeezes the return spring 204 to compress it, and at the same time drives the outer locking block 202 to retract towards the center of the connecting column 2 until the locking block 202 completely disengages from the annular locking groove 203 on the inner wall of the threaded hole of the rod body 1.
[0042] Separating the connecting post from the rod: While maintaining the force applied to the rotating plate 201 by the tool (the locking block 202 continues to disengage from the annular groove 203), rotate the connecting post 2 by the tool to make the connecting post 2 rotate outward along the threaded hole of the rod 1 until the connecting post 2 is completely separated from the original rod 1.
[0043] Installation steps
[0044] Pre-positioning connecting post: Take the new rod body 1, align the connecting post 2 with its threaded hole, and screw it in initially along the thread direction (the threaded connection provides initial positioning).
[0045] Locking: Insert the tool into the rectangular slot 206 of the rotating plate 201 again, drive the rotating plate 201 to rotate towards the center to compress the return spring 204, so that the locking block 202 remains in the retracted state; continue to rotate the connecting post 2 to the bottom of the threaded hole (fully screwed in).
[0046] Automatic reset locking: Release the external force of the tool on the rotating plate 201, the reset spring 204 elastically restores and pushes the rotating plate 201 to rotate outward around the pin axis (the free end slides back along the relief groove 205), causing the locking block 202 to pop outward and fully embed into the annular locking groove 203 of the threaded hole of the new roller body 1, forming an axial limit.
[0047] The dual fixing structure of "threaded pre-tightening + axial locking of the locking block 202 and the annular groove 203" not only ensures the quick assembly and disassembly of the connecting column 2 and the stick 1, but also effectively prevents the connecting column 2 from loosening due to vibration during the performance (especially when the stick rotates at high speed or collides), ensuring the safety and stability of the prop. The combination of the rectangular groove 206 and the anti-slip texture, as well as the guiding effect of the clearance groove 205, further enhances the convenience and reliability of operation.
