[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships that are based on the positions or location relationships when the product is in normal use.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0029] The utility model embodiment provides a support leg anti-pinch structure, combined with Figures 1 to 9 The structure and direction shown in the figure include a support leg 1 and a support leg cover 2 which are rotatably connected to each other. A slide plate 3 is movably connected between the support leg cover 2 and the support leg 1. When the support leg 1 rotates relative to the support leg cover 2, the slide plate 3 moves in the front-to-back direction to cover the rotation gap between the support leg 1 and the support leg cover 2. The initial state of the support leg 1 is the retracted state, and the working state of the support leg 1 is the expanded state. Figure 2 and Figure 4 As shown, when in the retracted state, the rotation angle between the support leg 1 and the support leg cover 2 is nearly 0 degrees, and when in the working state, the rotation angle between the support leg 1 and the support leg cover 2 is nearly 90 degrees. The support leg 1 rotates between 0-90 degrees when switching between the retracted state and the expanded state. Since there is a rotation gap between the support leg 1 and the support leg cover 2 when they rotate relative to each other, there is a risk of the user's fingers being caught in the rotation gap and getting injured. In addition, when used in a child safety seat, children are lively and active, and are more likely to put their hands into the rotation gap and get caught. Providing the slide 3 to cover the rotation gap can prevent the user's fingers from being caught in the gap and getting injured, eliminates the risk of the hand being caught when the support leg 1 rotates, has a simple structure, and is relatively low in cost.

[0030] like Figure 1As shown, the support leg cover 2 is provided with a torsion spring 4, and the two ends of the torsion spring 4 are connected to the support leg cover 2 and the slide 3 respectively. The slide 3 slides relative to the support leg cover 2 under the pressure of the torsion spring 4 and the support leg 1. The support leg cover 2 is provided with a fixed shaft, and the torsion spring 4 is sleeved on the fixed shaft. One end of the torsion spring 4 protrudes outward and abuts on the slide 3. When the support leg 1 switches from the unfolded state to the retracted state, the slide 3 is separated from the front side of the support leg cover 2 under the action of the torsion spring 4; when the support leg 1 is in the unfolded state, the slide 3 abuts against the front side of the support leg cover 2 under the pressure of the support leg 1. Under the action of the torsion spring 4, the slide 3 always follows the support leg 1. When the support leg 1 rotates back and forth, the slide 3 slides back and forth relative to the support leg cover 2. The force of the torsion spring 4 acting on the slide 3 is opposite to the force of the support leg 1 acting on the slide 3.

[0031] like Figures 6 to 8 As shown, a support column 31 is provided on the slide plate 3 , a slide groove 23 slidably matched with the support column 31 is provided on the support leg cover 2 , and the torsion spring 4 abuts against a side of the support column 31 away from the support leg 1 .

[0032] like Figure 7 As shown, taking the torsion spring 4 on the left side as an example, at this time, the support leg 1 is in a contracted state, and the torsion spring 4 is in a compressed state, with a tendency to rotate counterclockwise, so that the support column 31 is subjected to an upward elastic force and is abutted against the top of the slide slot 23, thereby covering the rotation gap of the support leg 1. The length direction of the slide slot 23 is consistent with the front-to-back direction, so that the support column 31 can move forward and backward in the slide slot 23, and the slide plate 3 can move forward and backward relative to the support leg cover 2, which has a simple structure and is stable and reliable.

[0033] like Figure 8 As shown, taking the torsion spring 4 on the left side as an example, at this time, the support leg 1 is in the expanded state, and the slide 3 is pushed to the bottom of the slide slot 23 by the support leg 1, fixing the slide 3 at the front end position of the support leg cover 2, and fitting closely with the front end of the support leg cover 2. At this time, one end of the torsion spring 4 is compressed to the bottom together with the slide 3. When the support leg 1 is retracted to the contracted state, the torsion spring 4 provides power for the slide 3 to return to its original state, and the slide 3 moves upward under the elastic force of the torsion spring 4 and returns to its original state.

[0034] The torsion spring 4 is cleverly designed, and cooperates with the supporting leg 1 inside the supporting leg cover 2 to push the slide 3, thereby adjusting the position of the slide 3, so that the slide 3 in the entire structure is placed inside the supporting leg cover 2, which is a hidden type and will not affect the movement of the supporting leg 1 or the overall appearance, thereby providing users with a good product experience.

[0035] like Figures 6 to 8 As shown, the slide 3 is provided with a block 32, and the support leg cover 2 is provided with a slot 24, and the block 32 is slidably engaged in the slot 24. The block 32 is provided with a guide surface, and when the slide 3 is installed, the guide surface provides a guiding function so that the block 32 can be smoothly engaged in the slot 24. When the support column 31 slides in the slide slot 23, the block 32 also slides synchronously in the slot 24.

[0036] like Figure 1 As shown, the support leg cover 2 includes a top cover 21 and a bottom cover 22, one end of the support leg 1 is built into the inner side of the bottom cover 22, the slide 3 is installed at the front end of the bottom cover 22, and the top cover 21 is arranged above the bottom cover 22. The slide slot 23 and the clamping slot 24 are both arranged at the front end of the bottom cover 22. When the support leg 1 is in the retracted state, it is almost parallel to the bottom cover 22, and when the support leg 1 is in the extended state, it is almost perpendicular to the bottom cover 22. When the support leg 1 turns from the retracted state to the extended state, the support leg 1 rotates in the direction away from the top cover 21; when the support leg 1 turns from the extended state to the retracted state, the support leg 1 rotates in the direction close to the top cover 21. When the support leg 1 is extended, the support leg 1 will squeeze the slide 3 to the front end of the bottom cover 22 and fit tightly with the inner wall of the bottom cover 22. The top cover 21 is covered on the bottom cover 22 to hide the internal parts and the rotating structure between the support leg covers 2, making it more dustproof and beautiful, and further preventing fingers from being pinched.

[0037] like Figure 3 and Figure 5 As shown, the slide 3 is provided with a first guide surface and a second guide surface, the first guide surface is matched with the support leg 1, and the second guide surface is matched with the support leg cover 2. The first guide surface and the second guide surface are respectively located at the two ends of the slide 3. When the support leg 1 rotates to the unfolded state, one end of the slide 3 abuts against the side wall of the support leg 1, and the first guide surface is matched with the shape of the side wall of the support leg 1. When the support leg 1 rotates to the unfolded state, the other end of the slide 3 abuts against the inner wall of the bottom cover 22, and the second guide surface is matched with the shape of the inner wall of the bottom cover 22.

[0038] like Figure 3and Figure 5 As shown, the first guide surface is an arc surface. In this embodiment, the side wall of the support leg 1 is in an arc shape, so the first guide surface is an arc surface. This arrangement allows the slide 3 to be pushed more smoothly when the support leg 1 rotates, avoiding jamming. At the same time, when the support leg 1 is in the unfolded state, the front side of the support leg 1 is completely in contact with the first guide surface, which can prevent the user from getting his hands caught.

[0039] like Figure 3 As shown, the slide 3 is built into the cover of the support leg 1. This built-in design allows the slide 3 to be hidden, does not affect the movement of the support leg 1, and does not affect the size of the anti-pinch structure 100 of the support leg 1, which can give users a good product experience.

[0040] like Figure 6 As shown, the slide 3 is a symmetrical structure. Two support columns 31 and two clamping blocks 32 are symmetrically arranged on the slide 3. Two slide slots 23 and two clamping slots 24 are correspondingly arranged on the support leg cover 2. The two torsion springs 4 are respectively abutted against the lower sides of the two support columns 31.

[0041] Another embodiment of the present invention provides a child safety seat, comprising the anti-pinch structure 100 of the support leg 1 as described above. Fig. 9 As shown, the child safety seat comprises a base, and the anti-pinch structure 100 of the support leg 1 is installed on the base.

[0042] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
