Description

Technical Field

[0001] The utility model relates to the technical field of baby carriages, in particular to a sliding folding frame and a baby carriage. Background Art

[0002] Baby strollers are generally configured to be foldable so that they can be folded up when not in use to relatively reduce the space occupied.

[0003] A baby stroller generally has a frame that can be converted between an unfolded state and a folded state, and a seat arranged on the frame. The child sits on the seat, and the parents push the stroller to move; when it is not needed, the child is taken out and the stroller is folded. Because the folded baby stroller is not easy to carry, it often needs to be placed in the trunk of a car or a storage place. For example, the patent number is CN213566084U, and the name is a baby stroller frame structure. Although the baby stroller frame can be folded, the entire frame structure is relatively complex, and because the folding is achieved by rotating the pin shaft, the folded frame occupies a large space and is not easy to carry; for example, the patent number is CN118163850A, and the name is a baby stroller folding frame. After folding, although it is easy to store, it is not easy to carry. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a sliding folding frame and a baby stroller.

[0005] According to the technical solution provided in the embodiment of the present application, a sliding folding frame and a baby carriage include a frame body, both side end faces of the frame body are provided with sliding holes, and a limiting shaft rod is slidably arranged in the sliding hole. A first sliding rod and a second sliding rod that are hinged to each other are movably sleeved on the limiting shaft rod, and the first sliding rod and the second sliding rod are hinged by a connecting rod A and a connecting rod B that are hinged to each other. When the limiting shaft rod slides to the upper end of the frame body, the first sliding rod and the second sliding rod are folded in parallel by the connecting rod A and the connecting rod B and folded in the frame body; when the limiting shaft rod slides to the lower end of the frame body, the angle between the first sliding rod and the second sliding rod increases with the increase of the hinge angle of the connecting rod A and the connecting rod B, so that the roller A at one end of the first sliding rod and the roller B at one end of the second sliding rod are placed on the ground on the same horizontal plane, thereby realizing the movement of the frame body.

[0006] Furthermore, the skeleton body is a trapezoidal frame structure which is narrow at the top and wide at the bottom. A limiting insertion hole for a limiting shaft rod is provided on the cross bar at the lower end of the skeleton body to prevent the limiting shaft rod from sliding in the sliding hole.

[0007] Furthermore, a protective plate is provided in the middle portion of the skeleton body, and two protective plates are respectively fixed on the left end surface and the right end surface of the skeleton body to improve the stability of the skeleton body.

[0008] Furthermore, the first sliding rod is hinged to one end of the connecting rod A, the other end of the connecting rod A is hinged to one end of the connecting rod B, and the other end of the connecting rod B is hinged to the second sliding rod, so that the first sliding rod and the second sliding rod can be flexibly folded and unfolded.

[0009] Furthermore, a pull rod is provided on the skeleton body, and the pull rod slides through the cross bar at the upper end of the skeleton body to facilitate the pushing and pulling of the skeleton body.

[0010] Furthermore, a protective shell is fixedly sleeved outside the skeleton body, a folding cushion is provided on one end face of the protective shell, and a storage bag is provided on the other end face through a zipper, so that the baby stroller can be folded and stored at the same time.

[0011] Furthermore, one end of the foldable seat cushion is connected to the protective shell, and the other end can be folded onto the end surface of the protective shell by a drawstring. The presence of the drawstring improves the load-bearing capacity of the foldable seat cushion.

[0012] In summary, the beneficial effects of the present application are as follows: the present application device utilizes the sliding hole design on the frame body to fold the first sliding rod and the second sliding rod in contact with the ground into the frame-type frame body, so that the entire sliding folding frame occupies a small volume and is easy to carry;

[0013] The baby stroller with the folding frame is convenient for people to easily change the use of the baby stroller during travel. When the baby stroller needs to be used, the folding frame is unfolded, the folding seat cushion is put down, and the folding frame is pushed by the pull rod to move it; when it is not needed, the folding frame is folded and placed on the end surface of the storage bag for easy carrying.

[0014] A zippered storage bag is provided on the stroller for easy storage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] A sliding folding frame, such as Figure 1 and Figure 2 As shown, the skeleton body 1 is a trapezoidal shape that is narrow at the top and wide at the bottom, and the inclined rods at the front and rear surfaces of the skeleton body 1 are provided with slides 101, and the horizontally placed limit shaft rod 2 passes through the slide hole 101. One end of the limit shaft rod 2 is fixed with a polygonal nut, and the other end is movably sleeved with the first slide rod 3 and the second slide rod 4. The first slide rod 3 and the second slide rod 4 can rotate relative to the limit shaft rod 2. The first slide rod 3 and the second slide rod 4 are hinged by a connecting rod A5 and a connecting rod B6 that are hinged to each other. The suspended ends of the first slide rod 3 and the second slide rod 4 are respectively provided with rollers A7 and rollers B8.

[0024] A protection plate 10 is provided in the middle of the skeleton body 1. The two protection plates 10 are respectively located at the front end and the rear end of the skeleton body 1, and the protection plates 10 are located in the middle between the upper end surface and the lower end surface of the skeleton body 1.

[0025] The skeleton body 1 is provided with a pull rod 11 that movably passes through the cross bar at the upper end thereof, and the cross bar at the lower end of the skeleton body 1 is provided with a limit hole 9 corresponding to the limit shaft rod 2. When the limit shaft rod 2 moves to the same horizontal plane as the limit hole 9, the limit shaft rod 2 can be inserted into the limit hole 9. Figure 2 As shown, a limit cylinder for limiting the position of the pull rod 11 is also provided on the cross bar at the lower end of the skeleton body 1;

[0026] like Figure 3As shown, the upper end of the first sliding rod 3 is hinged to the connecting rod A5 through a pin, the other end of the connecting rod A5 is hinged to one end of the connecting rod B6 through a pin, the other end of the connecting rod B6 is hinged to one end of the second sliding rod 4 through a pin, and the first sliding rod 3 and the second sliding rod 4 are not located on the same plane;

[0027] like Figure 1 and Figure 4 As shown, the protective shell 12 is fixedly sleeved on the skeleton body 1, a folding cushion 13 is provided on the rear end surface of the protective shell 12, and a storage bag 14 that is easy to disassemble is provided on the front end surface of the protective shell 12 through a zipper.

[0028] The protective shell 12 is made of nylon fabric fixed to the skeleton body 1 by screws, and a buffer pad is provided between the protective shell 12 and the skeleton body 1;

[0029] The folding cushion 13 is in a rectangular shape and can be made of rectangular nylon fabric. One end is fixedly connected to the protective shell 12, and the other suspended end is fixedly connected to the protective shell 12 through a drawstring. The other end of the drawstring is fixedly connected to the other end surface of the protective shell 12. When the folding cushion 13 is in use, the drawstring serves to realize that the folding cushion 13 is horizontal and has a certain load-bearing capacity.

[0030] In order to ensure that the folding seat cushion 13 does not appear to be unfolded when the stroller is carried, two permanent magnets with opposite magnetic properties can be placed inside the folding seat cushion 13 and at corresponding positions after being folded and overlapped with the protective shell 12, so that the folding seat cushion 13 can be adsorbed on the protective shell 12.

[0031] When using, Figure 1 and Figure 2 As shown, the limiting shaft rod 2 in the sliding holes 101 at the front and rear ends of the skeleton body 1 is slid in the sliding holes 101, so that the limiting shaft rod 2 moves down with the first sliding rod 3 and the second sliding rod 4 to a position at the same horizontal plane as the limiting insertion hole 9, and then the suspended end of the limiting shaft rod 2 is inserted into the limiting insertion hole 9, so that the limiting shaft rod 2 will not move up when bearing weight;

[0032] At this time, the first sliding rod 3 is rotated to the left relative to the limiting shaft rod 2, and the second sliding rod 4 is rotated to the right relative to the limiting shaft rod 2. Since the front end surface of the cross bar at the lower end of the skeleton body 1 is provided with a limiting hole, such as Figure 1 As shown, it is mainly used to limit the rotation angle of the first sliding rod 3. Similarly, when the second sliding rod 4 rotates, a limit block is also set on the skeleton body 1 - as shown in FIG. Figure 2As shown, the limit block is fixed on the frame rod and the limit insertion hole 9 at the side end of the skeleton body 1, so that the first sliding rod 3 and the second sliding rod 4 rotate an effective angle, so that the roller A7 and the roller B8 set at their suspended ends can be on the same horizontal plane, that is, they can be placed on the ground and roll at the same time to realize the movement of the skeleton body 1;

[0033] Therefore, when the outer end surface of the skeleton body 1 is provided with a protective shell 12, and the two end surfaces of the protective shell 12 are respectively provided with a folding cushion 13 and a storage bag 14, when the folding cushion 13 is needed to be used, the folding cushion 13 is rotated to 90 degrees with the protective shell 12, such as Figure 4 As shown, the drawstring is tightened at this time, and the child can directly sit on the folding cushion 13 which is 90 degrees to the protective shell 12, and the storage bag 14 can be used to store items;

[0034] When it is necessary to carry it, the first sliding rod 3 and the second sliding rod 4 are moved upward through the limiting shaft rod 2 and folded in the skeleton body 1, and then the folding cushion 13 is turned to be parallel to the end face of the protective shell 12, so that the folding cushion 13 is folded. After the first sliding rod 3, the second sliding rod 4 and the folding cushion 13 are folded and folded, the whole device is placed on the back of the storage bag 14. The appearance of the whole device is like a backpack, which is very small and easy to carry.

[0035] In this solution, a shoulder strap can be provided on the end surface of the protective shell 12 where the folding cushion 13 is provided, so that the entire device can be carried on the shoulder after being folded, which is more convenient to carry.

[0036] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
