[0001] The utility model relates to the technical field of children's articles and appliances, and particularly relates to a children's seat pull-out and rotary base device. Background Art

[0002] To meet the travel, dining and other needs of parents and children in life, a child safety carrier is usually installed on a baby stroller as part of the baby stroller, or installed on a child safety seat as part of a safety child seat. During use, the child carrier is usually used in combination with a base. The base is used as the base of the baby stroller or child safety seat, and then the child carrier is placed on the base and fitted and locked. To ensure safety during use, the firmness of the connection between the child carrier and the base is extremely important. In the existing technology of child safety seats, it is usually achieved by the elastic force of plastic materials or tightening clamps, but the firmness is relatively low, resulting in a lack of safety.

[0003] In this regard, to solve the problems existing in the prior art, those skilled in the art have made many efforts. For example, Chinese Patent Application CN 116373706 A proposes a child car seat with a side-shifting function; the rotating seat drives the sliding seat to rotate to the required orientation, which is convenient for placing the child in the vehicle seat or picking up the child from the vehicle seat, improving the use experience, but the structure is relatively complex and the use convenience is lacking.

[0009] Further, an eaves portion is provided at the upper end of the translation side rail; side wings are provided on the left and right sides of the drawable rotary seat; the upper eaves portion and the side wings cooperate with each other to prevent the drawable rotary seat from separating from the base during translation.

[0010] Further, a limiting portion extends outward from the upper part of the side wing; when the drawable rotary seat is translated to the limit distance, the limiting portion abuts against the inner side surface of the translation side rail to prevent the drawable rotary seat from being pulled out excessively.

[0011] Further, a rotary center rail is provided on the base; a U-shaped groove is provided at the bottom of the drawable rotary seat; the radian of the U-shaped groove is the same as that of the rotary center rail; when the drawable rotary seat is retracted, the rotary center rail abuts against the U-shaped groove to prevent the drawable rotary seat from translating excessively when retracted.

[0012] Further, center wings are provided on both sides of the rotary center rail; drawable sliding grooves are provided on both sides of the U-shaped groove; the drawable sliding grooves and the center wings cooperate with each other to prevent the drawable rotary seat from turning up during translation.

[0013] Further, a hovering pin is further provided at the bottom of the drawable rotary seat; the hovering pin is connected to the drawable rotary seat through a tension structure; one side of the hovering pin cooperates with the left and right sides of the rotary center member to form damping when the drawable rotary seat rotates to the left and right sides, so as to quickly find the drawable position.

[0014] Further, the unlocking structure includes an unlocking pin and an unlocking button; the unlocking pin is arranged in a receiving cavity in the base, and one end is connected to the unlocking button through a connecting band; a torsion spring is provided on one side of the unlocking pin; one end of the torsion spring abuts against the unlocking pin; unlocking grooves are provided on both the front and rear sides of the drawable rotary seat for cooperating with the unlocking pin to achieve the locking function.

Specific embodiments

[0032] The following further describes the technical solutions of the present utility model in conjunction with the accompanying drawings, but is not limited thereto. Any modification or equivalent replacement of the technical solutions of the present utility model without departing from the spirit and scope of the technical solutions of the present utility model shall be covered within the protection scope of the present utility model.

[0033] As Figures 1-6As shown in the figure, the present utility model provides a pull-out and rotatable base device for a children's seat, which is composed of a base 1 and a pull-out and rotatable seat 2. The pull-out and rotatable seat 2 is arranged on the base 1 and fits with the base 1. A rotating side rail 11 is provided on the base 1. The pull-out and rotatable seat 2 is matched with the base 1 through the rotating side rail 11 and can rotate relative to the base 1. Openings are provided on the left and right sides of the rotating side rail 11, and translation side rails 12 are provided on both sides of the openings. The translation side rails 12 are matched with the pull-out and rotatable seat 2, so that when the pull-out and rotatable seat 2 rotates to the vertical direction, that is, when facing left and right, it can make a translation movement depending on the translation side rails 12. A unlocking structure 14 is also provided on the front side of the base 1, which is used to cooperate with the pull-out and rotatable seat 2 to lock the pull-out and rotatable seat 2 when it does not need to rotate, and unlock it when rotation is required.

[0034] As shown in the figure, the pull-out and rotatable seat 2 is composed of a pull-out steel frame and a pull-out cover plate. The pull-out cover plate covers the pull-out steel frame and is fixed to the pull-out steel frame through a snap structure or bolts. Flanks 212 are provided on the left and right sides of the pull-out cover plate, and a limiting part 2121 extends outward from the front part of the flanks 212. The pull-out steel frame is composed of two side plates and a bottom plate. A U-shaped groove 224 is provided on the bottom plate, and pull-out sliding grooves 2241 are provided on both sides of the U-shaped groove 224. Second clamping parts 223 are fixedly connected to the front end and the rear end of the bottom plate. The second clamping parts are arc-shaped, and their arcs are consistent with the rotating side rail 11, and are used to cooperate with the rotating side rail 11.

[0035] First clamping parts 111 are provided on the front and rear sides of the rotating side rail 11. The first clamping parts 111 are fitted with the second clamping parts 223. By making the first clamping parts 111 and the second clamping parts 223 bite each other, the pull-out and rotatable seat 2 will not be separated from the base 1 during the rotation process, ensuring the stability and safety during its operation. The translation side rail 12 is concave, and an eaves part 121 is formed above. The eaves part 121 cooperates with the flanks 212 on the left and right sides of the pull-out cover plate, so that when the rotating pull-out base 1 makes a translation movement, the pull-out and rotatable seat 2 can be ensured not to turn up and other phenomena through the cooperation between the eaves part 121 and the flanks 212, ensuring the stability and safety during the translation process of the pull-out and rotatable seat 2. At the same time, during the process of the pull-out and rotatable seat 2 translating outward, the limiting part 2121 provided on the flanks 212 translates synchronously. When the cross section of the limiting part 2121 abuts against the inner end face of the translation side rail 12, it can block the translation movement of the pull-out and rotatable seat 2, thereby limiting the maximum translation distance of the pull-out and rotatable seat 2, and thus avoiding the pull-out and rotatable seat 2 from being pulled out excessively.

[0036] Preferably, a rotation center rail 13 is further provided on the base 1. The rotation center rail 13 is located at the center position of the rotation side rail 11 and is on the same straight line as the translation side rail 12. The rotation center rail 13 is circular in shape, and its radian is the same as that of the arc side of the U-shaped groove 224. The top of the rotation center rail 13 is in the shape of a counterbore, and there are break openings on both the left and right sides. A vertical baffle is provided on the front side of the break opening, and both ends of the vertical baffle are connected to the end faces of the break openings on both the left and right sides. Center wings 131 are provided on both the front and rear sides of the rotation center rail 13. The left and right sides of the center wings 131 are arc-shaped, and the front and rear sides are straight. There is a spacing between the two center wings 131, and the orientations of the two center wings 131 are the same as the opening orientation of the rotation side rail 11. When the pull-out rotating seat 2 makes a translation movement, the two center wings 131 respectively cooperate with the pull-out sliding grooves 2241 on both sides of the U-shaped groove 224, and together with the translation side rail 12, a double sliding track is formed, which can increase the smoothness of the pull-out rotating seat 2 during sliding. At the same time, it can form a pressing effect on the pull-out rotating seat 2, thereby further avoiding the phenomenon of the pull-out rotating seat 2 turning up, and further improving the stability and safety during the sliding process.

[0037] Preferably, a hovering plug pin 221 is further provided on the bottom plate of the pull-out steel frame. The hovering plug pin 221 is arranged at the front side of the U-shaped groove 224 and includes a hovering slider and a tension spring. The width of the hovering slider is adapted to the spacing between the two center wings 131, and the rear end is arc-shaped, and inclined surfaces are connected to both ends of the arc. Two hovering long grooves are provided at the front part of the hovering slider, and two hooks are provided at the rear part. There is a boss on the bottom plate, and two hooks are fixedly provided on the boss. The hovering slider is arranged on the boss and is slidably connected to the bottom plate, and the hooks on the bottom plate correspond to the positions of the hovering long grooves and extend out from the hovering long grooves. One end of the tension spring is connected to the hook on the hovering slider, and the other end is connected to the hook on the bottom plate. In the initial state, the pull-out rotating seat 2 is arranged in the front-rear direction. At this time, the tension spring is in a relaxed state, and the hook on the bottom plate is located at the front end of the hovering long groove. When the pull-out rotating seat 2 rotates to the arc side of the center wing 131, the center wing 131 will form a blocking effect on the hovering plug pin 221, thereby pushing the hovering plug pin 221 to move forward, causing the spring to be stretched and form a pulling force, and the hook on the bottom plate is located at the rear end of the hovering long groove. When the pull-out rotating seat 2 continues to rotate to the vertical direction, the hovering slider moves to the position between the two center wings 131, so that the hovering slider moves towards the direction close to the rotation center rail 13 under the pulling force of the tension spring, so that the end faces of the two center wings 131 respectively abut against the two inclined surfaces of the end face of the hovering slider, thereby forming a blocking effect, so that the pull-out rotating seat 2 can generate damping when rotating to the pull-out position, and quickly position to the pull-out position. When it is necessary to continue rotating the pull-out rotating seat 2, only an external force needs to be applied to the pull-out rotating seat 2 to push the pull-out rotating seat 2, so that the hovering slider slides in the direction away from the rotation center rail 13 under the thrust.

[0038] Preferably, as Figure 8 and 9 shown, the unlocking structure 14 includes an unlocking bolt 141 and an unlocking button 143. The unlocking bolt 141 is arranged in a receiving cavity inside the front side of the base 1 and can slide in the receiving cavity. The front end of the unlocking bolt 141 is connected to the unlocking button 143 through a connecting belt 144. A torsion spring 142 is arranged on one side of the unlocking bolt 141, and one end of the torsion spring 142 abuts against the unlocking bolt 141. During use, under the pressure of the torsion spring 142, the bolt extends towards the direction of the pull-out rotary seat 2 and reaches an unlocking groove provided on the pull-out rotary seat 2, thereby restricting the rotational movement of the pull-out rotary seat 2. When unlocking is required, the unlocking button 143 is pulled, and the bolt is driven to move forward through the connecting belt 144, so that it disengages from the unlocking groove, and at the same time, the torsion spring 142 accumulates elastic potential energy. At this time, the restriction on the rotational movement of the pull-out rotary seat 2 can be released; when locking again is required, only the unlocking button 143 needs to be released, and the unlocking bolt 141 extends out of the surface of the base 1 to the unlocking groove under the action of the torsion spring 142, and automatic locking can be achieved.

[0039] Preferably, as Figure 7As shown, a reverse limit assembly 23 is also provided on the pull-out rotating seat 2, and the reverse limit assembly 23 includes a reverse limit button 233 and a reverse limit latch 232; the reverse limit button 233 is arranged at a position corresponding to the rotating center rail 13 on the pull-out cover 2, and is slidably connected to the pull-out cover 2 through a slide, and a stopper is provided at the front and rear ends of the slide to limit the sliding distance of the reverse limit button 233, and both sides of the reverse limit button 233 extend forward with an extrusion portion 2331, and the extrusion portion 2331 is an inclined surface; the reverse limit pin 232 is located at the front end of the reverse limit button 233, and includes a limit column 2321 and a limit body 2322, the limit column 2321 is arranged on both sides of the limit body 2322, and is against the extrusion portion 2331; the limit body 2322 is a cube, and an accommodating groove 2323 is provided at the upper end, and a spring is provided in the accommodating groove 2323, one end face of the spring is against the bottom surface of the accommodating groove 2323, and the other end face is against the bottom surface of the pull-out cover. In the initial state, the limit column 2321 is located at the highest point of the inclined surface, and under the extrusion of the extrusion part 2331, the spring on the limit body 2322 is in a compressed state; when in use, when the rotation angle of the pull-out rotating seat is 0°-90° and 270°-360°, the reverse limit pin 232 is located above the rib position of the half side of the rotating center rail 13, and is restricted by the rib position and cannot move downward; when the rotation angle of the pull-out rotating seat 2 is 90°-279°, the reverse limit pin 232 is no longer below There is a raised rib position restriction. At this time, by toggling the reverse limit button 233, the limit column 2321 is at the lowest point of the inclined surface, so that the limit body 2322 can move downward under the elastic force of the spring, thereby causing the reverse limit pin 232 to move downward to the settled position of the rotating center rail 13, so that the vertical edge of the rib position, that is, the above-mentioned vertical plate, forms a block to the reverse limit pin 232, so that the pull-out rotating seat 2 cannot rotate in the reverse direction, thereby forming a reverse limit on it; conversely, the same applies to removing the restriction.

[0040] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
