DETAILED DESCRIPTION

[0023] In the following, the present application will be further described in conjunction with specific embodiments, and it should be noted that the embodiments described below or the technical features between the embodiments can be combined in any manner to form new embodiments without conflict.

[0024] In the description of the present application, it should be noted that for orientation words, such as the terms “center”, “transverse”, “longitudinal”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, “clockwise”, “counterclockwise”, etc. The orientation and positional relationship shown in the drawing is based on the orientation or positional relationship shown in the drawing, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] like Figures 1-7 The baby stroller seat shown includes a rectangular box 1. The bottom of the box 1 is equipped with casters 101. The number of casters 101 is equal to the number of corners at the bottom of the box 1, which is four. Each corner of the box 1 at the bottom is equipped with a caster 101, which can stably support the box 1 and allow the box 1 to move smoothly on the ground.

[0028] A first guide sleeve 3 made of plastic is fixedly connected to one side of the box body 1. An aluminum alloy handrail 4 is inserted into the first guide sleeve 3. The handrail 4 is held at a stable height by the first guide sleeve 3. The specific structure of the first guide sleeve 3 includes a pair of parallel connecting plates 302. Both connecting plates 302 are fixedly connected to the box body 1, and a limiting plate 301 is located between the sides of the two connecting plates 302 away from the box body 1. The limiting plate 301 is parallel to the side of the box body 1. When the box body 1 is in an upright position, the extension directions of the limiting plate 301 and the connecting plates 302 are both vertical. This allows the box body 1 to lean against the wall and maintain stability. Simultaneously, the regular shape of the box body 1 occupies less space and makes fuller use of the internal space. 301 has a first sliding groove 303 that runs through the inner and outer sides. The first sliding groove 303 extends along the length of the limiting plate 301. The inner wall of the first sliding groove 303 has first locking ribs 304 arranged at equal intervals. The first locking ribs 304 are not distributed near the upper and lower ends of the first sliding groove 303. The handrail 4 includes a hollow telescopic rod 401. The bottom side of the telescopic rod 401 has a sliding handle 403, which is used to cooperate with the first sliding groove 303 to form a sliding pair. It can be perfectly locked between adjacent first locking ribs 304, or between the first locking ribs 304 and the inner top wall or inner bottom wall of the first sliding groove 303. The upper end of the telescopic rod 401 is located outside the first guide sleeve 3 and is fixedly connected to a handle 402 for infants and young children to grasp.

[0029] The box body 1 is also fixedly connected with a second guide sleeve 5 made of plastic on the other side opposite to the first guide sleeve 3, and the second guide sleeve 5 is also inserted with a handle rod 6 made of aluminum alloy, the handle rod 6 can also be limited at a stable height by the second guide sleeve 5, and the handle rod 6 can rotate relative to the second guide sleeve 5 when reaching the upper limit position, specifically: the second guide sleeve 5 comprises a fixed plate 501 fixedly connected with the box body 1, the side surface of the fixed plate 501 is provided with a pair of parallel guide side plates 502, each guide side plate 502 is provided with a second sliding groove 503 penetrating the inner and outer walls, the inner wall of the second sliding groove 503 is provided with second clamping beads 504 arranged at equal distances, the second clamping beads 504 are also distributed at the positions of the two ends of the second sliding groove 503, and the specific structure of the handle rod 6 comprises a swing insertion rod 601, the bottom side surface of the swing insertion rod 601 is provided with a rotating sliding handle 603, which is used to form a sliding pair and a rotating pair with the second sliding groove 503, and can be perfectly clamped between adjacent second clamping beads 504 or between the second clamping beads 504 and the inner top arm or inner bottom wall of the second sliding groove 503, and the upper end of the swing insertion rod 601 is located outside the second guide sleeve 5 and is fixedly connected with a handle 602, which is mainly used for adults to hold, and of course can also be used for infants to hold.

[0030] In order to make the swing insertion rod 601 rotate more smoothly, the inner top wall of the second sliding groove 503 is semicircular, and the side edges of the two guide side plates 502 away from the fixed plate 501 are also provided with a blocking plate 505 for keeping the relative distance between the two guide side plates 502 stable, and the top surface of the blocking plate 505 and the inner walls of the two guide side plates 502 form a gap 506, the inner bottom surface of the gap 506 is lower than the axis height of the inner top wall of the second sliding groove 503, so that the swing insertion rod 601 is less hindered by the blocking plate 505 and can rotate in a larger range, the blocking plate 505 is parallel to the fixed plate 501, and when the box body 1 is placed vertically, the extension directions of the fixed plate 501, the guide side plates 502 and the blocking plate 505 are all vertical, and the top of the guide side plate 502 is also provided with a groove structure which is matched with the handle 602 lowered to the lower limit position, so as to hold the handle 602 and keep it stable.

[0031] The box body 1 can be opened from the side surface where the first guide sleeve 3 and the second guide sleeve 5 are not arranged, and a C-shaped extending zipper structure is usually arranged to facilitate the opening and closing of the box body 1, and the top surface of the box body 1 is provided with a cushion 2 made of soft and elastic foaming material, which is also wrapped with waterproof fabric, so that the infant sitting on it will be more comfortable.

[0032] Working principle: the baby stroller seat is not very suitable for very small babies, and is usually suitable for babies over one year old who can sit up. When in use, the box 1 can be opened, and various baby supplies can be placed inside. After closing the box 1, the universal wheels 101 are directed downward, the armrest rod 4 is pulled out, the baby is placed on the cushion 2, and the handle 402 is grasped. Since the lower end of the telescopic rod 401 is limited by the first clamping 304 in the first sliding groove 303, even if the baby exerts downward pressure on the handle 402, the height of the handle 402 will not easily decrease. Only when the parents use relatively large force can the first clamping 304 be deformed, thereby changing the height of the armrest rod 4. During the installation of the armrest rod 4 and the pull rod 6, the relatively inconspicuous translation slide handle 403 and the rotating slide handle 603 are embedded in the corresponding sliding grooves by extruding the plastic. When the box 1 needs to be moved, the parents can pull out the pull rod 6 until the rotating slide handle 603 slides to the upper limit of the second sliding groove 503, and then the swing rod 601 can be rotated. The parents can hold the handle 602 to move the baby sitting on the box 1 at a relatively low speed. Since the box 1 is not very high, and when the box 1 is moving, the baby will instinctively clench the box 1 with both legs and tightly hold the handle 402 with both hands, the baby can be well stabilized on the box 1, so the box 1 does not need to be additionally provided with a protective structure. The top of the box 1 is more spacious, which can facilitate the parents to change diapers and other operations for the baby on the box 1. When going out, the parents can to some extent free one hand.
