Description

Technical Field

[0001] This utility model relates to the field of kite pole technology, specifically a retractable and foldable kite pole. Background Technology

[0002] Flying kites is a popular parent-child leisure activity, which places special demands on the safety, portability, and durability of kite poles. Currently, most kite poles designed for children on the market adopt a simple pull-out structure, lacking standardized positioning and locking devices. This results in the inability to fold compactly when storing them, often requiring a large amount of space and causing inconvenience for children to carry and parents to store them.

[0003] Furthermore, the stability of these pull-out rod structures is generally poor, and the fit between the inner and outer rods is not precise enough. During transportation, they are prone to deformation due to collisions, and may even break when used by children due to improper force. A broken rod may create a sharp edge, posing a risk of cuts to children and seriously affecting safety. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing children's kite poles generally have poor structural stability, making them inconvenient to store, carry, and precisely adjust.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The present invention proposes a retractable kite pole, including an outer shell, the outer shell being a rod-shaped structure with a hand crank wheel in the middle, the outer shell also having a positioning component matched with the hand crank wheel, and a telescopic component inside the outer shell;

[0006] The telescopic assembly includes an outer rod with one end slidably disposed inside the outer shell and the other end penetrating and extending to the outside of the other end of the outer shell. An inner rod is slidably disposed inside the outer rod. A first limiting plate and a second limiting plate are disposed inside the gripping end of the outer shell. A first limiting groove is disposed on the outer wall of the outer rod near the first limiting plate. A second limiting groove is disposed at the end of the inner rod. The other end extends out of the end of the outer rod for connecting a kite string.

[0007] Preferred technical solution 1: The positioning component includes a limiting member rotatably mounted on the outer shell in the middle. One end of the limiting member is provided with a positioning protrusion. Multiple sets of positioning grooves are evenly distributed on the hand crank with its rotation axis as the center. A limiting post is provided on the outer shell at the position of the limiting member, and a support spring is sleeved on the limiting post. The other end of the support spring is connected to the bottom of the pressing end of the limiting member.

[0008] Preferred technical solution 2: The outer shell is designed in the shape of a sword.

[0009] Preferred technical solution three: The outer shell is assembled from two sets of half shells, and multiple sets of internally threaded posts are set in the length direction. The internally threaded posts are used in conjunction with screws to achieve fastening and locking. It also includes a locking cap that is connected to the head of the two sets of half shells by internal threads, so as to achieve overall stability and sturdiness of the shell. The locking cap has a taper inside, so that when the outer rod is pulled to a certain position, it cannot be pulled out, thus fixing it. Similarly, the cavity inside the outer rod for the inner rod to slide also has a certain taper, and the inner rod is pulled out to a certain length to complete the fastening.

[0010] Preferred technical solution four: The outer shell, telescopic component and positioning component are all made of ABS engineering plastic.

[0011] Preferred technical solution five: The size of the rocker wheel is reduced to a diameter of 6cm, and the surface is rounded; the extension stroke of the telescopic rod is limited to 29-66cm.

[0012] The retractable kite pole proposed in this utility model has the following beneficial effects achieved by adopting the above structure:

[0013] (1) Through the cooperation of the first limiting plate and the first limiting groove, the second limiting plate and the second limiting groove, and the precise engagement of the positioning protrusion and the positioning groove in the positioning component, the stability of the overall structure of the kite pole is effectively enhanced, and the precise control of the length of the line can be achieved, making it easy for children to operate.

[0014] (2) The outer and inner rods of the telescopic assembly can slide and retract into the outer shell. Combined with the rod-shaped structure and sword-shaped design of the outer shell, the storage volume of the kite pole is greatly reduced, making it convenient for children to carry with one hand and saving carrying space.

[0015] (3) Made of ABS engineering plastic, with a rocker wheel with a diameter reduced to 6cm and rounded corners, and a telescopic rod with a travel limit of 29-66cm, it avoids the sharp edge hazards of traditional metal parts, while also being suitable for the needs of flying small kites, preventing children from overstretching and causing structural damage, thus improving the safety and applicability of the product.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] Example 1

[0024] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: A retractable kite pole includes a shell 1, which is a rod-shaped structure with a hand crank 2 in the middle. To increase the stability of reeling in and out, a positioning component matching the hand crank 2 is also provided on the shell 1. A telescopic component is provided inside the shell 1. The telescopic component includes an outer rod 3, one end of which is slidably disposed inside the shell 1 and the other end of which passes through and extends to the outside of the other end of the shell 1. An inner rod 4 is slidably disposed inside the outer rod 3. A first limiting plate 5 and a second limiting plate 6 are provided inside the gripping end of the shell 1. The outer rod 3 rests against... A first limiting groove 7 is provided on the outer wall near one end of the first limiting plate 5, and a second limiting groove 8 is provided on the end of the inner rod 4. The other end extends out to the end of the outer rod 3 for connecting the kite string. By squeezing, the first limiting plate 5 and the first limiting groove 7 are engaged to fix the outer rod 3. The inner rod 4 is fixed by the engagement of the second limiting plate 6 and the second limiting groove 8. It is easy to store and avoids taking up a lot of carrying space. The outer shell 1 is designed in the shape of a sword. The outer shell 1 with the shape of a sword is used as the storage carrier for the kite rod. This design is in line with children's interests and preferences and is convenient for children to carry with one hand.

[0025] like Figure 3As shown, the positioning component includes a limiting member 9 rotatably mounted on the outer shell 1 in the middle. One end of the limiting member 9 is provided with a positioning protrusion 10. Multiple sets of positioning grooves 11 are evenly distributed on the hand crank 2 with its rotation axis as the center. The positioning grooves 11 cooperate with the positioning protrusions 10 to achieve precise positioning of the hand crank 2, making it easier to control the length of the line and making it easier for children to operate. A limiting post 12 is provided on the outer shell 1 at the position of the limiting member 9, and a support spring 13 is sleeved on the limiting post 12. The other end of the support spring 13 is connected to the bottom of the pressing end of the limiting member 9, so that after pressing, the positioning protrusion 10 disengages from the positioning groove 11, and after being released, it springs back into the corresponding limiting groove.

[0026] Example 2

[0027] Based on Example 1, such as Figure 2 As shown, to increase the overall stability of the outer shell 1, it is assembled from two sets of half-shells 14, with multiple sets of internally threaded posts along its length. These posts, in conjunction with screws, achieve a secure fastening. The outer shell also includes a locking cap 15, which is connected to the heads of the two sets of half-shells 14 via internal threads. This ensures the overall stability and robustness of the shell. The locking cap 15 has an internal taper, preventing further movement of the outer rod 3 once it is pulled to a certain position, thus securing it. Similarly, the cavity inside the outer rod 3 for the sliding of the inner rod 4 also has a taper, allowing the inner rod 4 to be pulled out a certain length for fastening. The outer shell 1, the telescopic assembly, and the positioning assembly are all made of ABS engineering plastic.

[0028] The size of the rocking wheel has been reduced to 6cm in diameter, and the surface is rounded to avoid the sharp edges of traditional metal rocking wheels; the extension stroke of the telescopic rod is limited to 29-66cm, which not only meets the needs of flying small kites, but also prevents children from overstretching and causing structural damage.

[0029] Specific usage instructions:

[0030] Adjust the length of the telescopic component to extend the outer rod 3. Hold the gripping end of the outer shell 1 and pull the outer rod 3 outward. One end of the outer rod 3 slides inside the outer shell 1, while the other end passes through and extends to the outside of the other end of the outer shell 1. During the pulling process, when the outer rod 3 is pulled to a certain position, due to the tapered design inside the locking cap 15, the outer rod 3 will be unable to continue pulling, thus achieving initial fixation of the outer rod 3. Similarly, the inner rod 4 is fixed.

[0031] Fold and store the outer rod 3. Push the outer rod 3 towards the first limiting plate 5 so that the first limiting plate 5 is engaged in the first limiting groove 7. Similarly, push the inner rod 4 inward so that it is engaged in the second limiting groove 8 by the second limiting plate 6 to complete the fixation.

[0032] When it is necessary to rewind or unwind the line, press the pressing end of the limiting piece 9. At this time, the support spring 13 sleeved on the upper limit post 12 of the outer shell 1 is compressed, the positioning protrusion 10 disengages from the positioning groove 11, releases the positioning of the hand crank 2, and the hand crank 2 is turned to rewind or unwind the line.
