[0002] In recent years, consumers have tended to choose child safety seats with support legs to provide extra stability and support, reducing the risk of injury to children in accidental collisions. However, the support legs sometimes accidentally open during use or transport, leading to hand trapping incidents and potentially causing injury and inconvenience to children and parents. Summary of the Invention
[0003] To address at least one of the aforementioned problems, the present invention first provides a support leg with an anti-pinch function, comprising a support leg body and a fixed base hinged together, wherein an anti-pinch assembly is movably connected between the support leg body and the fixed base, the anti-pinch assembly comprising an anti-pinch plate and an elastic element connected together, wherein both ends of the elastic element are respectively connected to the anti-pinch plate and the fixed base; the support leg body is in a folded state, and when in the folded state, a gap is formed between the support leg body and the fixed base, and the anti-pinch plate blocks the gap under the elastic force of the elastic element.
[0004] Optionally, the support leg body also has a supporting state, in which the anti-pinch plate is hidden inside the fixing seat when it is in the supporting state.
[0005] Optionally, the elastic element is a pull rope, the fixed base is connected to a rotating shaft, the support leg body is hinged to the fixed base through the rotating shaft, and the two ends of the pull rope are respectively connected to the anti-pinch plate and the rotating shaft.
[0006] Optionally, the anti-pinch piece includes a connecting portion and a blocking portion that are connected to each other. The connecting portion is connected to the elastic member, and when in the folded state, the blocking portion covers the outside of the notch.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0026] In the description of this invention, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.
[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0028] This invention provides a support leg with anti-pinch function, combined with Figures 1 to 8 As shown, the device includes a support leg body 1 and a fixed base 2 that are hinged together. An anti-pinch assembly 3 is movably connected between the support leg body 1 and the fixed base 2. The anti-pinch assembly 3 includes an anti-pinch plate 31 and an elastic element 32 that are connected together. The two ends of the elastic element 32 are respectively connected to the anti-pinch plate 31 and the fixed base 2. The support leg body 1 is in a folded state. When it is in the folded state, a gap 4 is formed between the support leg body 1 and the fixed base 2. The anti-pinch plate 31 blocks the gap 4 under the elastic force of the elastic element 32.
[0029] Among them, the elastic element 32 can be an elastic rope, a tension spring, or a compression spring, which has a certain elastic force to help keep the anti-pinch plate 31 tightly fitted when folded, thereby completely covering the notch 4. The elastic element 32 can also provide a certain degree of flexibility and stability when the support leg body 1 changes state. The design of the anti-pinch plate 31 covering the notch 4 can be either to cover the notch 4 or to abut against the edge of the notch 4. The anti-pinch plate 31 can effectively prevent the user's fingers or other objects from entering the notch 4, reducing the risk of pinching. The support leg body 1 can rotate around the fixed base 2 to change state, that is, switch between the folded state and the support state to adapt to different usage scenarios.
[0030] When the seat is in use, the support leg body 1 can be unfolded to support the seat. The anti-pinch plate 31 of the anti-pinch component 3 will move as the support leg body 1 unfolds, keeping the notch 4 covered. When the seat needs to be folded or moved, the support leg body 1 is in a folded state. The anti-pinch plate 31 will be acted upon by the elastic element 32, tightly fitting and covering the notch 4, thereby preventing children's fingers or other objects from being pinched.
[0031] In this embodiment, the support leg with anti-pinch function has an anti-pinch component 3 between the support leg body 1 and the fixed seat 2. The anti-pinch piece 31 can fit tightly against and cover the notch 4 under the action of the elastic member 32, so that the user's hand has no chance to put into the notch 4. Even if the support leg body 1 is accidentally opened during the use and transportation of the seat, the user will not accidentally pinch their hand. This effectively prevents the occurrence of hand pinching incidents. The structure is simple and reliable, and can provide a safer and more reliable child safety seat experience while maintaining the stability of the seat.
[0032] Optionally, combined Figure 8 As shown, the support leg body 1 also has a supporting state. When in the supporting state, the anti-pinch plate 31 is hidden inside the fixed base 2, so that the anti-pinch plate 31 will not affect the appearance of the support leg body 1 when it is in the supporting state, thereby achieving non-destructive operation. The end of the anti-pinch plate 31 away from the connecting part 311 abuts against the inner wall of the fixed base 2 under the elastic force of the elastic member 32. When it is necessary to support the support leg body 1, the anti-pinch plate 31 will be slowly stored in the fixed base 2 as the support leg body 1 is rotated and opened, ensuring the stable storage of the anti-pinch plate 31, and at the same time, it will not have any adverse effects on the overall appearance or use of the support leg.
[0033] Optionally, combined Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the elastic element 32 is a pull rope, the fixed base 2 is connected to a rotating shaft 5, the support leg body 1 is hinged to the fixed base 2 through the rotating shaft 5, and the two ends of the pull rope are respectively connected to the anti-pinch plate 31 and the rotating shaft 5.
[0034] The pull rope is preferably made of rubber, which has good elasticity and resistance to breakage. When the pull rope is under tension, it can achieve adaptive adjustment of the support leg body 1 and the anti-pinch plate 31 through elastic deformation. The pull rope is connected to the rotating shaft 5. When the state of the support leg body 1 changes, the pull rope will adjust its shape according to the change of tension, thereby avoiding the anti-pinch plate 31 from getting stuck and maintaining the normal state of the support leg body 1. The elastic element 32 adopts a pull rope design, which is simple and reliable in structure. The anti-pinch plate 31 can always be in contact with the fixed seat 2 through the pull force of the pull rope to cover the notch 4. The two ends of the elastic element 32 are respectively sleeved and connected to the anti-pinch plate 31 and the rotating shaft 5, and the connection is firm and reliable.
[0035] In this embodiment, the support leg body 1 is hinged to the fixed base 2 through the rotating shaft 5, which makes the support leg body 1 more stable when unfolding and folding, and ensures that the tension of the pull rope is transmitted to the anti-pinch plate 31, thereby realizing the position adjustment of the anti-pinch plate 31.
[0036] Optionally, combined Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, the anti-pinch plate 31 includes a connecting portion 311 and a blocking portion 312 connected to each other. The connecting portion 311 is connected to the elastic member 32. When in the folded state, the blocking portion 312 covers the outside of the notch 4. The connecting portion 311 and the elastic member 32 work together to ensure that the anti-pinch plate 31 fits tightly against the notch 4, preventing external objects from entering and thus reducing the risk of pinching. The area of the blocking portion 312 of the anti-pinch plate 31 is not less than the area of the notch 4, that is, the edge of the blocking portion 312 can extend beyond and cover the edge of the notch 4, so that the blocking portion 312 can completely cover the notch 4, effectively preventing objects from entering the notch 4 and further improving safety.
[0037] Optionally, combined Figure 4 , Figure 5 , Figure 6 As shown, the end of the shielding part 312 away from the connecting part 311 is provided with a limiting guide block 3121, which is adapted to abut against the inner wall of the notch 4.
[0038] The limiting guide block 3121 is designed to protrude inward toward the inside of the fixed base 2, further ensuring that the blocking part 312 always fits tightly against the notch 4 when the support leg body 1 is folded. The limiting guide block 3121 also has a guide surface, which guides the anti-pinch plate 31 to smoothly enter the fixed base 2 during the opening of the support leg body 1. Generally, the internal space of the fixed base 2 is small. After the anti-pinch plate 31 enters the fixed base 2, the end of the blocking part 312 away from the connecting part 311 will abut against the inner wall of the fixed base 2. The abutment force overcomes the elastic force of the elastic member 32, causing the anti-pinch plate 31 to move relative to the tube plug 6. The elastic member 32 is stretched to store force, so that when the support leg body 1 is switched to the folded state, the anti-pinch plate 31 can move and reset under the pulling force of the elastic member 32 to ensure that the notch 4 is blocked.
[0039] Optionally, combined Figure 2 , Figure 3 , Figure 5 As shown, the support leg body 1 is connected to a pipe plug 6, and the pipe plug 6 is provided with a mounting hole 61 suitable for cooperating with the limiting guide block 3121. When switching from the folded state to the supported state, the mounting hole 61 will cooperate with the limiting guide block 3121 to prevent the anti-pinch piece 31 from deflecting during movement, making the structure more stable and reliable. There are two limiting guide blocks 3121, so there are also two mounting holes 61. The limiting guide blocks 3121 and the mounting holes 61 are set one-to-one to ensure the stability of the movement of the anti-pinch piece 31 relative to the pipe plug 6.
[0040] Optionally, combined Figures 2 to 8 As shown, the support leg body 1 is connected to a pipe plug 6, the pipe plug 6 is provided with a through hole track 62 that is slidably connected to the shielding part 312; the connecting part 311 is provided with a limiting protrusion 3111 that is suitable for abutting against the edge of the through hole track 62.
[0041] The shielding part 312 is a sheet-like structure, and the through-hole track 62 is an elongated hole. The shielding part 312 can move freely up and down within the through-hole track 62 to ensure that the shielding part 312 maintains a stable movement trajectory during the folding and unfolding of the support leg body 1. When in the folded state, the limiting protrusion 3111 abuts against the edge of the through-hole track 62 to prevent the anti-pinch piece 31 from disengaging from the through-hole track 62. The tube plug 6 is connected to one end of the support leg body 1, and the anti-pinch piece 31 is movably connected to the support leg body 1 through the tube plug 6.
[0042] In this embodiment, the tube plug 6 is provided with a through-hole track 62 for the anti-pinch plate 31 to slide up and down, the anti-pinch plate 31 is provided with a limiting guide block 3121, and the tube plug 6 is provided with a mounting hole 61 that cooperates with the limiting guide block 3121. This cooperation mainly sets the stroke of the anti-pinch plate 31 when it slides on the through-hole track 62 of the tube plug 6. The connecting part 311 of the anti-pinch plate 31 is connected to the elastic member 32. The other end of the elastic member 32 is fixed on the rotating shaft 5. The support leg body 1 is fixed on the fixed base 2 through the rotating shaft 5. The support leg body 1 can be rotated, folded and stored and opened through the rotating shaft 5. At the same time, the anti-pinch plate 31 can adjust its state in real time according to the state change of the support leg body 1 to maintain a stable anti-pinch function.
[0043] Optionally, combined Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the tube plug 6 is also provided with an installation groove 63 for mounting the elastic element 32. The design of the installation groove 63 can prevent the elastic element 32 from deviating and maintain the stability and reliability of the anti-clamping plate 31.
[0044] Optionally, combined Figure 1 , Figure 4 As shown, the connecting part 311 is provided with a connecting hole 3112 for connecting with the elastic member 32, which facilitates a firm connection between one end of the elastic member 32 and the connecting part 311, and the structure is simple and reliable.
[0045] Another embodiment of the present invention provides a child safety seat, including a support leg with anti-pinch function as described above.
[0046] In this embodiment of the child safety seat, an anti-pinch component 3 is provided between the support leg body 1 and the fixed seat 2, so that the anti-pinch plate 31 can fit tightly and cover the notch 4 under the action of the elastic member 32. In this way, the user's hand will not have the opportunity to put into the notch 4, so that the user will not accidentally pinch their hand if the support leg body 1 is accidentally opened during use and transportation of the seat. This effectively prevents the occurrence of hand pinching incidents. The structure is simple and reliable, and can provide a safer and more reliable child safety seat user experience while maintaining the stability of the seat.
[0047] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
