Detailed Description
The drawings illustrate the structure of the present invention, and details thereof are further described below with reference to the drawings. This child safety seat's landing leg prevents tong mechanism, including landing leg 1 and base, the base is including base lower cover 7 and base upper cover 9, base upper cover 9 sets up on base lower cover 7, be equipped with left and right sides base owner side pipe 61, 62 in the base lower cover 7, be equipped with landing leg support 5 between the left and right sides base owner side pipe front end, landing leg 1 top is equipped with landing leg mounting 2, and landing leg mounting 2 rotates and installs on landing leg support 5, be equipped with on the rotation gap of landing leg 1 and base and prevent tong 4, rotate the installation mouth that the gap corresponds for the adjacent angular position of landing leg and base rotation contained angle, prevent tong 4 rotatable business turn over base, and prevent being equipped with limit structure between tong 4 upper end and the base, prevent tong 4 by landing leg drive rotation.
The anti-pinch member 4 comprises an arc-shaped shell with a U-shaped cross section, inner flanges 41 are arranged on two side walls of the shell, driving grooves 42 are formed in the inner flanges 41, left and right guide members 31 and 32 are arranged on two sides of the supporting leg 1, sliding grooves 312 and 322 and driving blocks 33 are formed in the guide members, the inner flanges 41 are arranged in the sliding grooves in a sliding mode, and the driving blocks 33 are limited to move in the driving grooves 42. The limit structure is a bulge 43 arranged at the upper end of the side wall of the anti-pinch piece 4, and the bulge 43 is matched with the base mounting opening in a clamping way.
In the invention, the top of the supporting leg 1 is propped against the fixing plate 21 of the supporting leg fixing piece 2 to be welded, the supporting leg supporting piece 5 is connected with the through hole 611 of the left base main square tube 61 through the hole 511 on the left side by bolts, and the hole 521 on the right side of the supporting leg supporting piece 5 is connected with the through hole 621 of the right base main square tube 62 by bolts, as shown in figure 3. The left and right guide members 31, 32 are fixed to the leg fixing member 2 by the protruding points 311 in cooperation with the fixing holes 22 of the leg fixing member 2. The inner flanges 41 of the two side walls of the anti-pinch member 4 are inserted into the sliding grooves 312 and 322 of the guide member, the driving blocks 33 of the guide member are arranged in the driving grooves 42 formed by the inner flange notches of the anti-pinch member 4, and the anti-pinch member 4 can rotate along the driving grooves 42 to a certain extent as shown in figure 5. The through holes 23 in the leg fixing member 2 are aligned with the through holes 53 in the leg support member 5, and by penetrating the leg fixing pin 8, the two can perform relative rotational movement. After all the parts are assembled, the whole assembly is assembled to the base lower cover 7, and the two outer side walls of the left base main square tube and the right base main square tube respectively prop against the left limiting wall 71 and the right limiting wall 72 of the base lower cover; the left and right side walls of the anti-pinch member 4 respectively prop against two limiting posts 73, 74 of the base lower cover 7, as shown in fig. 4, and finally the base upper cover 9 is mounted on the base lower cover 7 according to the hole positions.
The working principle is that when the supporting leg is folded, the supporting leg 1 drives the guide piece to rotate downwards through the supporting leg fixing piece 2, when the lower end of the driving block 33 of the guide piece props against the lower end of the driving groove 42 of the anti-pinch piece 4, the anti-pinch piece 4 is driven to rotate downwards to the angle shown in fig. 6, the protrusions at the upper end of the side wall of the anti-pinch piece limit the anti-pinch piece to drop out of the base, and therefore the rotating gap between the supporting leg 1 and the lower cover 7 of the base is eliminated, and the whole attractiveness of a product is maintained. The driving block 33 on the guide piece limits the anti-pinch piece 4 to rotate in a reasonable range in the opening and closing process of the supporting leg 1, so that the gap between the anti-pinch piece and the guide piece is kept in a small range all the time, and the pinch is avoided as shown in fig. 7; when the product is used correctly, the supporting leg 1 is opened to the maximum angle, the supporting leg 1 drives the supporting leg fixing piece 2 to rotate upwards, the upper edge of the driving block 33 of the guide piece props against the upper edge of the driving groove 42 of the anti-pinch piece 4 to drive the anti-pinch piece to rotate upwards together until the upper top surface of the driving block props against the supporting surface 54 of the supporting leg supporting piece 5 as shown in fig. 8, and the anti-pinch piece 4 is hidden in the base lower cover 7, so that the attractive appearance of the product is maintained.
In summary, the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
