Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for manufacturing child safety seats, and more specifically, to a foot pedal assembly fixture for child safety seats. Background Technology

[0002] The assembly of the footrest is a crucial step in the production of child safety seats. However, traditional methods of assembling the footrest for child safety seats have many shortcomings.

[0003] First, assembly efficiency is low. In the past, manual assembly was used, requiring operators to rely on experience and manual tools to install and position each component. This process was tedious and time-consuming. For example, when installing components such as slide rails, valve bodies, foot pedals, and back plates, repeated adjustments to the position and finding the appropriate installation angle were necessary, which greatly affected the overall assembly speed and made it difficult to meet the needs of large-scale production.

[0004] Secondly, assembly quality is difficult to guarantee, as manual assembly is greatly affected by the skill level and working condition of the operators. Different operators have different assembly techniques and force, which can easily lead to low assembly accuracy and insufficient fit between components. For example, the connection between the slide rail and other components may become loose, or the foot pedal may be installed at an inaccurate angle. This not only affects the appearance of the child safety seat, but may also pose a potential threat to its safety.

[0005] In addition, traditional assembly methods lack effective positioning and support structures. During the assembly process, it is difficult for each component to be stably positioned and supported, which can easily lead to displacement or shaking, further increasing the difficulty of assembly and reducing assembly efficiency and quality. Utility Model Content

[0006] Based on the aforementioned technical problems, this utility model proposes a child safety seat footrest assembly tool, which achieves rapid and precise assembly of the child safety seat footrest by rationally designing the structure and combination of each component.

[0007] A tooling for assembling a child safety seat footrest includes: The base has a front support limit block, a valve body support limit block, a foot pedal support block, and a rear support limit block arranged sequentially from front to back. The front support limiting block is provided with a front guide rail on each of its two sides at the top, and a front vertical groove is provided on the outer side of the front guide rail. The valve body support limiting block is a U-shaped structure with a concave center, and limiting slots are provided on the side platforms on both sides. The upper part of the rear support limiting block is provided with a recessed platform on each side, and a rear guide rail is provided on the recessed platform. The front guide rail is directly opposite the rear guide rail on the same side. A rear vertical groove is provided on the outer side of the recessed platform, and the rear vertical groove is directly opposite the front vertical groove. There are two foot pedal support blocks, symmetrically arranged between the valve body support limit block and the rear support limit block.

[0008] Furthermore, a locking block is provided at the outer end of the limiting slot, and the width of the locking block is smaller than the width of the limiting slot.

[0009] Furthermore, a boss is provided on the front side of the front support limiting block.

[0010] Furthermore, a front limiting platform is provided on the rear side of the upper end of the front support limiting block, and a rear limiting platform is provided on the front side of the upper end of the rear support limiting block. The surfaces of the two limiting platforms are on the same horizontal plane, and the limiting platforms are lower than the upper surface of their respective support limiting blocks.
