Description

Technical Field

[0001] The utility model relates to a telescopic device, in particular to a telescopic device for a toy sword, and belongs to the technical field of toys. Background Art

[0002] Toy swords are a popular toy for children, and swords with retractable mechanisms are even more popular. The most common retractable mechanisms on toy swords currently on the market are spring-loaded. These mechanisms consist of multiple retractable plastic sections with springs installed inside. Pressing a button on the hilt or triggering a mechanism compresses or releases the spring, pushing the sections of the blade forward or backward in sequence, achieving the blade's retractable function. While this structure is relatively simple, cost-effective, and allows for rapid retraction, the spring may fatigue over time, resulting in awkward retraction or inability to fully extend or retract the blade. Furthermore, the spring's limited force can impair the retracting effect if the blade is too long or heavy. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides an electric telescopic device adopting a screw structure.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a telescopic device for a toy sword, including a driving mechanism, a nut and screw lifting structure and a multi-stage telescopic sword body, the driving mechanism drives the nut and screw lifting structure to rotate, the multi-stage telescopic sword body is connected to the nut and screw lifting structure and performs telescopic movement with the rotation of the nut and screw lifting structure.

[0005] Preferably, the driving mechanism includes a motor and a reducer, and the motor drives the nut and screw lifting structure to rotate through the reducer.

[0006] Preferably, the nut and screw lifting structure includes a threaded rod, a multi-stage nut and a limit rod. The multi-stage nut is connected to the multi-stage telescopic sword body. The multi-stage nut drives the multi-stage telescopic sword body to perform linear telescopic motion as the threaded rod rotates. The limit rod is arranged next to the threaded rod and at the lower end of the multi-stage nut.

[0007] Preferably, the multi-stage nut includes an upper nut and multiple lower nuts, the upper nut is at the upper end of the multiple lower nuts, the multiple lower nuts are provided with holes, and the limiting rod passes through the holes. When the multi-stage telescopic sword body shrinks, the lower end of the upper nut is against the limiting rod.

[0008] Preferably, the multi-stage nut is provided with an inner protrusion, a hook, and a push rod. The inner protrusion engages with the threaded rod, and the hook and push rod are connected to the multi-stage telescopic blade. The multi-stage telescopic blade is tapered, with a guide slot, an open slot, and a small hole connected to the hook at its lower end. The push rod is inserted into the open slot, and a protrusion is provided at the upper end of the push rod. The upper end of the multi-stage telescopic blade is internally provided with a slot corresponding to the guide slot and a groove corresponding to the protrusion at the upper end of the push rod.

[0009] Preferably, a lamp bead and a sound-generating device are provided at the lower end of the nut and screw lifting structure.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. Strong portability: Through the rotation and telescopic design of the nut and screw, the sword body can be retracted into the handle, greatly reducing the overall volume. 2. Stable structure: The threaded engagement of the nut and the screw is a rigid connection. Compared with the spring telescopic or snap-on structure, it is not easy to loosen during the telescopic process. After unfolding, the connection between the sword body and the handle is more stable, reducing the risk of shaking or falling off during use. 3. High adjustment accuracy: The pitch design of the screw can achieve precise control of the length of the sword body. The user can gradually adjust the extension length of the sword body by rotating the nut to meet the "simulated sword swinging" needs of different scenarios. 4. Simple structure and easy production: The nut and screw are standard mechanical parts, the mold development cost is low, and the accuracy is controllable during mass production. It is suitable for low-cost large-scale manufacturing of toys, reducing terminal sales prices and improving market competitiveness. 5. Easy maintenance: If problems such as telescopic jamming occur, it is usually only necessary to apply a small amount of lubricant or clean the dust in the thread to repair it. No complicated tools are required. Users can handle it by themselves, reducing after-sales costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1-12The figure shows a telescopic device for a toy sword, comprising a drive mechanism 3, a nut and screw lifting structure 2, and a multi-stage telescopic blade 1. The drive mechanism 3 drives the nut and screw lifting structure 2 to rotate. The drive mechanism 3 includes a motor and a reducer, which drives the nut and screw lifting structure 2 to rotate via the reducer. The nut and screw lifting structure 2 includes a threaded rod 21, a multi-stage nut, and a limiting rod 22. The multi-stage nut is connected to the multi-stage telescopic blade 1. As the threaded rod 21 rotates, the multi-stage nut drives the multi-stage telescopic blade 1 to perform linear telescopic motion. The limiting rod 22 is positioned adjacent to the threaded rod 21 and at the lower end of the multi-stage nut. The multi-stage nut includes an upper nut 23 and multiple lower nuts 24. The upper nut 23 is located at the upper end of the multiple lower nuts 24. The multiple lower nuts 24 are provided with holes 25 through which the limiting rod 22 passes. When the multi-stage telescopic blade 1 retracts, the lower end of the upper nut 23 abuts the limiting rod 22. The multi-stage nut is provided with an inner protrusion 26, a hook 27, and a push rod 28. Internal protrusion 26 engages with threaded rod 21, while hook 27 and push rod 28 connect to the multi-stage telescopic blade 1. The multi-stage telescopic blade 1 is tapered, with a guide slot 29, an opening 30, and a small hole 31 connected to hook 27 at its lower end. The push rod is inserted into the opening 30, and a protrusion is provided on the upper end of push rod 28. The upper end of the multi-stage telescopic blade 1 is internally provided with a slot 32 corresponding to the guide slot 29 and a groove 33 corresponding to the protrusion on the upper end of push rod 28. A light bulb 34 and a sound-generating device are located at the lower end of the nut and screw lifting structure 2. When the multi-stage telescopic blade 1 moves, it emits light and sound, simulating the light and sound of a laser sword, providing a more realistic experience.

[0026] like Figure 11 As shown, the multi-stage nuts are connected to the corresponding multi-stage telescopic blades according to their size: the hook is inserted into the small hole, and the push rod is inserted into the open slot, so that the nut and blade are fixed together and cannot move up and down or left and right. Then, the connected nuts and blades are threaded through the threaded rod in order of size. The hole in the lower nut should pass through the limit rod. The lower end of the uppermost lower nut will contact the upper end of the limit rod, at which point the motor will stop working. The multi-stage telescopic blades should be strung together in order of size, and the guide groove at the bottom of the previous blade should be inserted into the groove of the next blade. This ensures that the blades cannot rotate relative to each other.

[0027] like Figure 12 As shown: the motor starts and drives the threaded rod to rotate. The upper nut at the top has the smallest diameter and rises the fastest. When it reaches the top of the threaded rod, the bump on the upper end of the push rod will be stuck in the groove of the next sword body. After the upper nut is separated from the threaded rod, the sword body driven by the lower nut at the lower end will lift the sword body in front and continue to rise.
