Description

Technical Field

[0001] This utility model relates to the field of children's climbing frame technology, and in particular to a children's training climbing frame that is easy to replace. Background Technology

[0002] In the field of children's climbing training, the design of traditional climbing frames often suffers from several unresolved problems. First, the frame structure of many climbing frames is not well-designed, failing to provide a stable and safe climbing environment. These frames often employ simple rectangular or square structures, which are not only visually uncoordinated but also fail to meet children's needs for balanced support and a good climbing experience at different heights and angles. Furthermore, traditional climbing frames typically use fixed installations, which not only occupy a significant amount of space but also make changing the climbing frames extremely inconvenient. Parents or coaches cannot quickly and easily change the climbing frames to different heights or angles according to the child's training needs, thus limiting the training effectiveness and the child's climbing experience.

[0003] Meanwhile, the traditional methods of fixing training ladders also pose certain safety hazards. Many ladders are fixed with fasteners such as screws or bolts. This method is not only cumbersome to install and disassemble, but also prone to loosening or falling off during use, posing a potential risk to children's safety. In addition, although some training ladders use a snap-fit ​​method, the design of the snap-fit ​​structure is not reasonable enough, which can easily cause the ladder to sway or fall off during climbing, further increasing the safety hazards. Utility Model Content

[0004] This utility model relates to an easily replaceable children's training climbing frame, aiming to solve the problems existing in traditional training climbing frames in terms of structural design, functional implementation, and safety performance. It achieves this through the adoption of an isosceles trapezoidal frame structure, a clever snap-fit ​​method, a stable quick-lock design, and a self-locking frame structure.

[0005] In a first aspect, this utility model provides a children's training climbing frame that is easy to replace, specifically comprising: a training climbing frame frame; the training climbing frame frame is an isosceles trapezoidal frame structure, with training climbing ladders respectively installed in the two inclined surfaces of the training climbing frame frame; quick-lock sleeves are vertically provided at the middle positions of the two inclined outer side walls of the training climbing frame frame, with quick-lock cores inserted into the quick-lock sleeves, and the inner ends of the quick-lock cores being inserted into the side walls of the training climbing ladders; a self-locking frame is vertically provided at the middle position of the upper back side wall of the training climbing ladder.

[0006] Optionally, columnar connecting rods are fixed at the two inclined upper and lower ends of the training climbing frame.

[0007] Optionally, the upper and lower ends of the back of the training ladder are respectively provided with L-shaped slots. When the training ladder is tilted and installed on the training frame, the slots are in a vertical state and the slots are engaged with the connecting rods. When the training ladder is installed, it is first pushed inward and then moved downward. The connecting rod is inserted from the lower end of the slot to the top of the vertical section of the slot. The training ladder is in a fixed state in the left, right and down directions.

[0008] Optionally, the quick-lock sleeve is provided with a quick-lock guide screw hole with a spiral of 316 degrees, and a lever is vertically fixed on the outer end side wall of the quick-lock core. The lever is placed in the quick-lock guide screw hole, and both ends of the quick-lock guide screw hole are at the bottom of the quick-lock sleeve. When the lever rotates from the inner end to the outer end along the quick-lock guide screw hole, the quick-lock core moves from the inside to the outside, and the inner end of the quick-lock core separates from the training ladder.

[0009] Optionally, a self-locking rod is vertically provided on the self-locking frame. The inner end of the self-locking rod is slidably placed in the slot, and the outer end of the self-locking rod is a ball head. A retaining ring is fixedly installed on the self-locking rod on the outer wall of the slot. A spring is fitted on the self-locking rod between the retaining ring and the self-locking frame. When the connecting rod is inserted from below the slot, the connecting rod squeezes the self-locking rod outward and the connecting rod passes through. Under the action of the spring, the connecting rod is locked below the connecting rod.

[0010] This utility model provides a children's training climbing frame that is easy to replace, and has the following beneficial effects:

[0011] First, the training climbing frame adopts an isosceles trapezoidal frame structure. This design not only provides children with a stable and safe climbing environment, but also ensures that children receive balanced support and a good climbing experience at different heights and angles. The isosceles trapezoidal structure makes the entire climbing frame more visually harmonious and also conforms to ergonomic principles, allowing children to move more comfortably and naturally during climbing.

[0012] Training ladders are cleverly fitted onto the two sloping surfaces of the training frame. This design not only saves space but also makes changing the ladders extremely convenient. The sloping, snap-fit ​​mechanism securely fixes the ladders to the frame, avoiding the safety hazards associated with traditional fixing methods. Furthermore, this snap-fit ​​method allows parents or instructors to quickly and easily adjust the ladders to different heights or angles to meet the child's training needs.

[0013] To further enhance the stability of the training ladder, this invention also incorporates a combination of a quick-lock sleeve and a quick-lock cylinder. This design not only improves the ladder's secure hold but also simplifies and speeds up disassembly and replacement. By rotating the lever, the quick-lock cylinder can be easily moved inwards and outwards, thus unlocking and securing the training ladder. This quick-lock design not only improves operational efficiency but also ensures the safety and stability of the training ladder during use.

[0014] Furthermore, the design of the self-locking frame and its components, including the self-locking bar, retaining ring, and spring, further enhances the stability of the training ladder. When the connecting rod engages from below the slot, the self-locking bar is compressed and springs outward, allowing the connecting rod to pass smoothly. After the connecting rod has passed, the spring forces the self-locking bar to quickly rebound and lock underneath the connecting rod, effectively preventing the training ladder from wobbling or falling off during use. This design not only improves the stability of the training ladder but also provides children with a safer and more reliable climbing environment.

[0015] In summary, the easily replaceable children's training climbing frame proposed in this invention demonstrates significant beneficial technical effects in terms of structural design, functional implementation, and safety performance. It not only provides children with a stable, safe, and easily replaceable climbing environment but also greatly improves training efficiency and ease of operation, making it an ideal choice for children's climbing training.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 4 :

[0030] This utility model proposes a children's training climbing frame that is easy to replace, including: a training climbing frame frame 1; the training climbing frame frame 1 is an isosceles trapezoidal frame structure, and training climbing ladders 2 are respectively installed in the two inclined surfaces of the training climbing frame frame 1; quick-lock sleeves 3 are respectively vertically provided at the middle position of the two inclined outer side walls of the training climbing frame frame 1, and quick-lock core pins 302 are inserted into the quick-lock sleeves 3, with the inner end of the quick-lock core pins 302 inserted into the side wall of the training climbing ladder 2; a self-locking frame 4 is vertically provided at the middle position of the upper back side wall of the training climbing ladder 2.

[0031] Among them, columnar connecting rods 101 are fixed at the two inclined upper and lower ends of the training climbing frame 1.

[0032] The training ladder 2 has L-shaped slots 201 at both the top and bottom ends of its back. When the training ladder 2 is tilted and installed on the training frame 1, the slots 201 are in a vertical position and are engaged with the connecting rod 101. When the training ladder 2 is installed, it is first pushed inward and then moved downward. The connecting rod 101 is inserted from the lower end of the slot 201 to the top of the vertical section of the slot 201. The training ladder 2 is locked in place in the left, right and down directions.

[0033] The quick-lock sleeve 3 is provided with a quick-lock guide screw hole 301 with a spiral of 316 degrees. A lever 3021 is vertically fixed on the outer side wall of the quick-lock core 302. The lever 3021 is placed in the quick-lock guide screw hole 301. Both ends of the quick-lock guide screw hole 301 are at the bottom of the quick-lock sleeve 3. When the lever 3021 rotates from the inner end to the outer end along the quick-lock guide screw hole 301, the quick-lock core 302 moves from the inside to the outside. The inner end of the quick-lock core 302 separates from the training ladder 2.

[0034] In Example 2, based on Example 1, a self-locking rod 401 is vertically provided on the self-locking frame 4. The inner end of the self-locking rod 401 is slidably placed in the slot 201, and the outer end of the self-locking rod 401 is a ball head. A retaining ring 402 is fixedly installed on the self-locking rod 401 on the outer wall of the slot 201. A spring 403 is fitted on the self-locking rod 401 between the retaining ring 402 and the self-locking frame 4. When the connecting rod 101 is inserted from below the slot 201, the connecting rod 101 squeezes the self-locking rod 401 outward and the connecting rod 101 passes through. Under the action of the spring 403, the connecting rod 101 is locked below the connecting rod 101.

[0035] The working principle of this embodiment:

[0036] The training climbing frame 1 is designed as an isosceles trapezoidal frame structure, providing children with a stable and safe climbing environment. Training ladders 2 are cleverly installed on the two sloping surfaces of the training climbing frame 1, allowing children to practice climbing at different heights and angles.

[0037] The training ladder 2 has L-shaped slots 201 at both the top and bottom of its back. These slots 201 are in a vertical position when the training ladder 2 is tilted and fitted onto the training frame 1. When installing the training ladder 2, it is first pushed inward and then moved downward. At this time, the connecting rod 101 (fixed at both ends of the two inclined surfaces of the training frame 1) will engage from the slot at the bottom of the slot 201 to the top of the vertical section of the slot 201. This design ensures that the training ladder 2 is locked in place in the left, right, and down directions, thus ensuring its stability during use.

[0038] To further enhance the stability of the training ladder 2, a combination of a quick-lock sleeve 3 and a quick-lock core 302 is designed. The quick-lock sleeve 3 is vertically positioned at the midpoint of the outer side walls of the two inclined sides of the training ladder frame 1, while the quick-lock core 302 is inserted into the quick-lock sleeve 3, with its inner end fitting into the side wall of the training ladder 2. The quick-lock sleeve 3 has a quick-lock guide screw hole 301 with a 316-degree spiral, and a lever 3021 is vertically fixed to the outer side wall of the quick-lock core 302. When it is necessary to disassemble the training ladder 2, the lever 3021 can be rotated from the inner end to the outer end along the quick-lock guide screw hole 301. At this time, the quick-lock core 302 will move from the inside to the outside, thereby separating its inner end from the training ladder 2, thus realizing the function of quick unlocking and replacement.

[0039] Furthermore, the design of the self-locking frame 4 further enhances the stability of the training ladder 2. A self-locking rod 401 is vertically mounted on the self-locking frame 4. The inner end of the self-locking rod 401 slides into the slot 201, while the outer end has a ball-head design. A retaining ring 402 is fixedly installed on the self-locking rod 401 on the outer wall of the slot 201, and a spring 403 is fitted onto the self-locking rod 401 between the retaining ring 402 and the self-locking frame 4. When the connecting rod 101 is engaged from below the slot 201, it compresses the self-locking rod 401, allowing it to pass smoothly. After the connecting rod 101 has passed, the spring 403 causes the self-locking rod 401 to re-lock below the connecting rod 101, further securing the position of the training ladder 2 and preventing it from shaking or falling off during use.
