Description

Technical Field This invention relates to the field of child safety seat technology, specifically to a support leg anti-pinch structure and child safety seat. Background Technology Child safety seats are essential items for infants and children traveling in vehicles. To prevent the child safety seat from moving due to inertia during sudden braking and other situations, a support leg is generally set at the front end of the support leg cover, which can also be retracted when not in use. However, in existing support legs, there is a gap between the support leg and the support leg cover during use. When fingers are placed in this gap, they can easily be pinched by the support leg, causing injury. CN 114425974 discloses a child safety seat with a support leg. Disclosure Content To solve at least one aspect of the above problems, this invention first provides a support leg anti-pinch structure, including a support leg and support leg cover rotatably connected to each other, with a sliding piece movably connected between the support leg cover and the support leg. When the support leg rotates relative to the support leg cover, the sliding piece moves in the front-back direction to cover the rotational gap between the support leg and the support leg cover. Optionally, the support leg cover is provided with a torsion spring, the two ends of the torsion spring are connected to the support leg cover and the sliding piece respectively, and the sliding piece slides relative to the support leg cover under the pressure of the torsion spring and the support leg. Optionally, the sliding piece is provided with a support column, the support leg cover is provided with a sliding groove that slidably matches with the support column, and the torsion spring abuts against the side of the support column facing away from the support leg. Optionally, when the support leg switches from the extended state to the retracted state, the sliding piece separates from the front side of the support leg cover under the action of the torsion spring; when the support leg is in the extended state, the sliding piece abuts against the front side of the support leg cover under the pressure of the support leg. Optionally, the sliding piece is provided with a locking block, the support leg cover is provided with a locking slot, and the locking block is slidably engaged in the locking slot. Optionally, the support leg cover includes a top cover and a bottom cover, one end of the support leg is embedded inside the bottom cover, the sliding piece is installed at the front end of the bottom cover, and the top cover is covered on top of the bottom cover. Optionally, the sliding piece is provided with a first guide surface and a second guide surface, the first guide surface matches with the support leg, and the second guide surface matches with the support leg cover. Optionally, the first guide surface is an arc surface. Optionally, the sliding piece is embedded inside the support leg cover. Compared to existing technology, the support leg anti-pinch structure of this disclosure prevents users' fingers from being pinched in the gap during rotation due to the presence of a rotational gap between the support leg and support leg cover. The sliding piece covering this gap eliminates the risk of hand pinching during support leg rotation, with a simple structure and low cost. Moreover, the entire structure has the sliding piece placed inside the support leg cover, making it concealed, without affecting the movement of the support leg or the overall external dimensions, providing users with a good product experience. Additionally, this invention provides a child safety seat that includes the aforementioned support leg anti-pinch structure. Compared to existing technology, the child safety seat of this invention has the same advantages as the aforementioned support leg anti-pinch structure relative to existing technology, which will not be repeated here.
