Technical Field
[0001] This utility model belongs to the field of trolley technology, and specifically relates to a folding stool structure for trolleys. Background Technology
[0002] A trolley is a common mode of transport, mostly used for short-distance transport. Users can use a trolley to transport goods to places that are inconvenient for cars to access.
[0003] Most trolleys on the market consist of a handle and a bracket. Wheels are mounted on the bracket, allowing the user to move it by pulling on the handle. For user convenience, some trolleys include a seat. For example, a shopping cart disclosed in Chinese utility model patent application CN201821114569.0 includes a frame, a telescopic handle, a U-shaped seat frame, two hinged sleeves (first, second, and third), a support frame (first and second). The telescopic handle is telescopically connected to the frame. The two hinged sleeves (first and second) are respectively fitted onto the side bars on both sides of the frame. The two hinged sleeves (third) are mounted on the telescopic handle. A [missing information - likely a design element] is provided between the two hinged sleeves (first, second, and third). The vehicle is equipped with connecting rods that are fixedly connected to the frame and the telescopic handle. Hinge sleeve one and hinge sleeve three are respectively positioned opposite to hinge sleeve two. A flat frame is hinged to hinge sleeve one, and a soft bag is placed on the flat frame. A rain shield is hinged to hinge sleeve three, and the rain shield is covered with sun-protective black rubber sheet. The rain shield is convex in shape and has a rainwater trough for collecting rainwater. The rainwater trough has a through hole inside, and a flexible hose is connected to the through hole. The U-shaped seat cushion frame is horizontally positioned, and both ends of the U-shaped seat cushion frame are hinged to hinge sleeve two. Support frame one and support frame two are cross-shaped at their middle sections to form a cross frame, which supports the U-shaped seat cushion frame.
[0004] Although the U-shaped seat frame in the above structure can be flipped and folded towards the cart frame, the relative position of the U-shaped seat frame and the cart frame is fixed when in use. If the ground is uneven and the user sits on the U-shaped seat frame, it is easy to cause the shopping cart to tilt, affecting the normal use of the shopping cart. Summary of the Invention

[0018] The advantages of this utility model compared to the prior art are:
[0019] 1. In this utility model, since the first bracket and the second bracket are connected to the mounting frame through the first slide and the second slide respectively, the structure is simple and easy to manufacture. When the ground is uneven or there are steps, the stool body can slide relative to the mounting frame, thereby raising and lowering the height of the stool body, which is convenient for users. The retractable base rod and extension rod can reduce the volume of the folding stool structure after folding, making it easier to store and transport the folding stool structure. The setting of the limiting component can prevent the first slide and the second slide from sliding onto the extension rod, which can facilitate the stable sliding of the first slide and the second slide and prevent the first slide and the second slide from affecting the relative contraction of the base rod and the extension rod.
[0020] 2. The connection part or connector in this utility model facilitates the stable unfolding or folding of the first and second supports, making it convenient for the use, storage, and transportation of the trolley. Since one end of the stool surface is provided with a sleeve for mounting the crossbar, and the other end of the stool surface is detachably connected to the first slide, it is convenient for the disassembly and installation of the stool surface. In addition, no additional mounting rod is required on the first support in this structure, which helps to simplify the structure of the folding stool for the trolley. Since the mounting crossbar can be flipped up to the top of the first slide, it is convenient to reduce the volume of the stool after folding, making it convenient for the folding, storage, and transportation of the folding stool.
[0021] 3. The flexible material of the stool surface in this utility model facilitates the flexible rotation of the first and second supports, making it convenient for users. The setting of the pressure plate is conducive to the stable installation of the stool surface and the first slide. The pressure plate presses the stool surface against the side of the first slide away from the first support, which helps to reduce the stress on the pressure plate during use, avoid deformation or damage to the pressure plate, and help to extend the service life of the folding stool structure. The perforation setting can prevent the stool surface from affecting the connection between the first slide and the mounting frame, which is conducive to the stable installation of the stool surface.
[0022] 4. In this utility model, multiple uprights facilitate the stable installation of the folding stool structure. Since the first slide and / or the second slide are respectively connected to two uprights, it is beneficial to the stable installation of the folding stool structure, preventing the two uprights from moving closer together due to the force on the stool surface, avoiding deformation or damage to the uprights, and helping to extend the service life of the folding stool structure. The retractable base rod and extension rod make it easy for the user to control the movement of the trolley. Since the first slide and the second slide are both slidably mounted on the base rod, and the setting of the limiting parts and the base plate can prevent the first slide and the second slide from detaching from the base rod, the relative sliding of the base rod and the extension rod does not affect the normal use of the stool, making it convenient for the user.
[0023] 5. In this utility model, since the limiting components are fixedly connected to the two uprights respectively, and the lower ends of the two uprights are respectively installed in the two mounting grooves, it is conducive to the stable installation of the uprights, avoids the two uprights from moving closer together due to the force on the stool surface, avoids deformation or damage to the uprights, and helps to extend the service life of the folding stool structure; the setting of the rod body and the groove facilitates the first and second supports to fully flip and fold towards the uprights, reduces the volume of the trolley during the folding process, and facilitates the storage and transportation of the trolley.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0034] See Figures 1 to 6 As shown, a folding stool structure for a trolley includes a stool body and a mounting frame for mounting the stool body. A first slide 6 and a second slide 7 are slidably mounted on the mounting frame. The stool body includes a stool surface 5, a first support 3, and a second support 4. The first support 3 and the second support 4 are rotatably connected and can be unfolded or brought closer together. The first support 3 and the second support 4 can combine with the stool surface 5 to form a triangular structure. The first support 3 and the second support 4 are rotatably connected to the first slide 6 and the second slide 7, respectively, allowing the stool body to slide relative to each other along the mounting frame. The first slide 6 and the second slide 7 can move relative to each other, allowing the first support 3 and the second support 4 to unfold or fold relative to each other. Because the first support 3 and the second support 4 are connected to the mounting frame via the first slide 6 and the second slide 7, the structure is simple and easy to manufacture. When the ground is uneven or there are steps, the stool body can slide relative to the mounting frame, thereby raising and lowering the height of the stool body for user convenience.
[0035] The mounting frame includes a retractable base rod 11 and an extension rod 12. The first slide 6 and the second slide 7 are both slidably mounted on the base rod 11, and a limiting member 13 is provided on the base rod 11. The limiting member 13 can prevent the first slide 6 and the second slide 7 from detaching from the base rod 11 and moving onto the limiting member 13. The retractable base rod 11 and the extension rod 12 facilitate the reduction of the volume of the folding stool structure after folding, making it easier to store and transport the folding stool structure. The limiting member 13 can prevent the first slide 6 and the second slide 7 from sliding onto the extension rod 12, facilitating the stable sliding of the first slide 6 and the second slide 7, and preventing the first slide 6 and the second slide 7 from affecting the relative contraction of the base rod 11 and the extension rod 12.
[0036] The mounting bracket described in this utility model is provided with a connecting part or connector, which can be detachably connected to the first bracket 3 or the second bracket 4, thereby restricting the relative rotation of the first bracket 3 and the second bracket 4. The connection part or connector facilitates the stable unfolding or folding of the first bracket 3 and the second bracket 4, making it convenient for the use, storage and transportation of the trolley. Although the connecting part or connector is not shown in the accompanying drawings of this utility model, those skilled in the art can implement this technical solution according to their own needs.
[0037] The upper part of the first bracket 3 is rotatably connected to the first slide 6. The upper part of the second bracket 4 is provided with a mounting crossbar 41. The mounting crossbar 41 and the first slide 6 are respectively connected to the stool surface 5 and support the stool surface 5. One end of the stool surface 5 is provided with a sleeve 51 that connects to the mounting crossbar 41. The other end of the stool surface 5 is detachably connected to the first slide 6. This structure facilitates the disassembly and installation of the stool surface 5. In addition, no additional mounting rod is required on the first bracket 3 in this structure, which helps to simplify the structure of the folding stool for the trolley.
[0038] In this embodiment, the first bracket 3 and the second bracket 4 are rotatably connected by the first hinge shaft 8. The distance between the first hinge shaft 8 and the mounting crossbar 41 is greater than the distance between the first hinge shaft 8 and the first slide block 6 bracket. Controlling the first bracket 3 and the second bracket 4 to move closer together can make the mounting crossbar 41 flip up to the top of the first slide block 6. This structure makes it easier to reduce the volume of the folded stool and facilitates the folding, storage, and transportation of the folding stool.
[0039] Preferably, the stool surface 5 is made of a flexible material. The first slide 6 is fitted onto the mounting frame. The stool surface 5 extends from above the first slide 6 to the side of the first slide 6 away from the first support 3. A pressure plate 9 is detachably installed on the first slide 6. The pressure plate 9 presses the stool surface 5 against the side of the first slide 6 away from the first support 3. The stool surface 5, made of flexible material, facilitates the flexible rotation of the first support 3 and the second support 4, making it convenient for the user. The installation of the pressure plate 9 is conducive to the stable installation of the stool surface 5 and the first slide 6. Since the pressure plate 9 presses the stool surface 5 against the side of the first slide 6 away from the first support 3, it helps to reduce the force on the pressure plate 9 during use, avoid deformation or damage to the pressure plate 9, and help to extend the service life of the folding stool structure. In this embodiment, the stool surface 5 is bent towards the side of the first slide 6 to form a bent part 53, and the pressure plate 9 presses the bent part 53 against the first slide 6.
[0040] In this embodiment, the stool surface 5 is provided with a through hole 52. The mounting bracket passes through the first slide 6 and the through hole 52 and extends to the upper and lower sides of the stool surface 5. The through hole 52 can prevent the stool surface 5 from affecting the connection between the first slide 6 and the mounting bracket, which is conducive to the stable installation of the stool surface 5.
[0041] A trolley includes a folding stool structure for the trolley. A base plate 2 is connected to the mounting frame, and wheels 23 are rotatably mounted on the base plate 2. At least two uprights 1 are provided on the mounting frame. A first slide 6 and / or a second slide 7 are slidably connected to the two uprights. The multiple uprights 1 facilitate the stable installation of the folding stool structure. Since the first slide 6 and / or the second slide 7 are respectively connected to the two uprights 1, it is beneficial to the stable installation of the folding stool structure, avoids the two uprights from moving closer together due to the force on the stool surface 5, avoids deformation or damage to the uprights, and helps to extend the service life of the folding stool structure.
[0042] The upright 1 described in this utility model includes a retractable base rod 11 and an extension rod 12. The base rod 11 is detachably connected to the base plate 2. The first slide 6 and the second slide 7 are both slidably mounted on the base rod 11, and a limiting member 13 is provided on the base rod 11. The first slide 6 and the second slide 7 are both located between the limiting member 13 and the base plate 2, thereby limiting the relative position of the stool on the mounting frame. The retractable base rod 11 and the extension rod 12 facilitate the user's control of the trolley movement. Since the first slide 6 and the second slide 7 are both slidably mounted on the base rod 11, and the limiting member 13 and the base plate 2 are provided, the first slide 6 and the second slide 7 can be prevented from detaching from the base rod 11. The relative sliding of the base rod 11 and the extension rod 12 does not affect the normal use of the stool, making it convenient for the user.
[0043] The limiting member 13 is fixedly connected to the two uprights 1 respectively, and the base plate 2 is provided with two mounting grooves 22. The lower ends of the two uprights 1 are respectively installed in the two mounting grooves 22. This structure is conducive to the stable installation of the uprights 1, avoids the two uprights from coming close together due to the force on the stool surface 5, avoids deformation or damage of the uprights, and helps to extend the service life of the folding stool structure.
[0044] In this utility model, the wheel 23 is rotatably mounted on the base plate 2 via a rotating shaft 24, and the rotating shaft 24 passes through the mounting groove and rotatably connects the upright 1 to the base plate 2.
[0045] In this embodiment, the first support 3 includes several vertically extending rods 31. The side of the base plate 2 is provided with a groove 21 that is adapted to the rods 31. By controlling the first support 3 and the second support 4 to move closer to each other, the rods 31 can be flipped into the grooves 21. The arrangement of the rods 31 and the grooves 21 is conducive to the first support 3 and the second support 4 being fully flipped and folded toward the upright 1, reducing the volume of the trolley during the folding process and facilitating the storage and transportation of the trolley.
[0046] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
