[0001] The application belongs to the technical field of folding chairs, and particularly relates to a foldable temporary seat structure for urban public squares. BACKGROUND

[0002] Urban public squares currently play a very huge role in cities, and are places where citizens often gather and rest. However, most urban public squares have limited areas, and therefore need to use folding seats to replace traditional seats, which can be folded when not in use, effectively saving space and enabling the square to flexibly hold various activities. The foldable temporary seat structure for urban public squares realizes the foldability of the seat through ingenious structural design, is convenient to store and maintain, can be flexibly adjusted in use according to actual needs, and provides people with a convenient and comfortable resting place.

[0003] A foldable outdoor resting seat is disclosed in Publication No. CN221330716U, which comprises a seat cushion and a seat back, two side walls of the seat cushion are each provided with a first rotating shaft, and the shaft walls of the two first rotating shafts are each rotatably connected with a rotating plate, two side walls of the seat back are each fixedly provided with a second rotating shaft, and the shaft walls of the two second rotating shafts are each rotatably connected with the side wall of the same side rotating plate, the side walls of the two rotating plates are each threadedly connected with a limiting bolt at both ends, and the bottom of the seat cushion is provided with a supporting mechanism. The seat of the application can be used for people to sit and rest, and can also be changed in form to be used as a table, enriches the functionality of outdoor park seats, and reduces the limitations of seat use.

[0004] However, it is found in actual use that: since folding seats are used by many children in public places, and the folding seat mainly folds the seat back and the seat surface of the chair, but during folding, the folding process may cause the fingers of children to be pinched, so that the folding seat is complained by parents, and actual use will be inconvenient to a certain extent, and therefore a corresponding structure needs to be added to prevent pinching of the fingers of children. CONTENT OF THE UTILITY MODEL

[0005] The application aims to solve the problem of adding a corresponding structure to prevent pinching of the fingers of children, and provides a foldable temporary seat structure for urban public squares.

[0006] The technical solution adopted in this application is as follows: a foldable temporary seat structure for urban public squares, wherein a connecting shaft is inserted into the side surface of the backrest base plate, a connecting plate is inserted into one end of the connecting shaft relative to the side surface of the backrest base plate, a rotating groove is provided on the side surface of the connecting plate, a blocking shaft is slidably inserted into the rotating groove through a slot, a blocking base is connected to the side surface of the connecting plate, a reset spring plate is connected to the side surface of the blocking base, a plurality of connecting bolts are inserted into the side surface of the blocking base, an anti-drop ring is fixedly connected to the side surface of the connecting shaft, and a seat surface is fixedly connected to the side surface of the connecting plate.

[0007] By adopting the above technical solution, the operator uses the backrest base plate as the base component of the chair. The inserted shaft and connecting upright plate on it serve as connecting components to drive the backrest base plate to rotate. Then, a sliding component formed by a rotating slide groove and a blocking shaft ensures that the rotation of the backrest base plate is within a track. A blocking component formed by a blocking base, a reset spring plate, and connecting bolts then blocks the blocking shaft. An anti-drop ring serves as an anti-detachment component, and the seat surface serves as the seat of the chair. Through these components, the operator can achieve a mechanical barrier between the chair back and seat surface during folding, creating a certain gap space when they come into contact. This prevents injuries such as pinching from children during operation.

[0008] The backrest base plate, serving as the base component of the chair back, is used to drive the chair back to flip, forming a simple chair structure with the seat. The backrest base plates are connected mainly through a plug-in joint between the plug shaft and the connecting upright plate, stringing the backrest base plates together to create a certain degree of flipping effect.

[0009] Then, a sliding damping shaft on the rotating groove serves as a blocking component, its movement throughout the assembly allowing it to contact subsequent damping components. The damping component primarily utilizes a damping base, which is slotted with a U-shaped upper end. A reset plate within the base has a spring structure at its bottom for resetting. Connecting bolts are used for installation; it is installed when needed and removed when not in use. Anti-detachment rings inserted into the side surface of the plug-in shaft prevent detachment. Finally, the seat serves as the chair's seating component for the user to sit on.

[0010] In a preferred embodiment, a plurality of support rods are fixedly connected to one end of the chair surface opposite to the connecting upright plate, and support columns are inserted into the side surfaces of the support rods.

[0011] By adopting the above technical solution, the chair can be used at different heights by utilizing the synergistic effect between the support rod and the support column.

[0012] In a preferred embodiment, a connecting bolt is inserted into the side surface of the support column, and a connecting base is fixedly connected to the side surface of the backrest base plate.

[0013] By adopting the above technical solution, the support rod and support column are connected together by connecting bolts, and then the connecting base is used to connect the backrest of the chair.

[0014] In a preferred embodiment, a connecting shaft is inserted into the side surface of the connecting base, and a connecting clamp is rotatably inserted into the connecting shaft relative to one end side surface of the connecting base.

[0015] By adopting the above technical solution, using the connecting shaft as a connecting component, the connecting clamp and the connecting base are inserted together and a certain degree of rotatability is formed, so that the backrest component of the chair can be adjusted in angle.

[0016] In a preferred embodiment, a chair back is fixedly connected to the side surface of the connecting clamp, and a lumbar support pad is fixedly connected to the side surface of the chair back.

[0017] By adopting the above technical solution, the chair back is used as the backrest component of the chair, and the lumbar support pad is used to support the waist, thereby enhancing the user experience.

[0018] In a preferred embodiment, a rotation limiting nut is rotatably inserted into one end side surface of the connecting shaft relative to the connecting clamp, and a handle is fixedly inserted into the side surface of the rotation limiting nut.

[0019] By adopting the above technical solution, a rotating limit nut is used as a limiting component, and it is tightened to fix the flip angle of the chair back.

[0020] In a preferred embodiment, an auxiliary limiting block is fixedly connected to the upper surface of the connecting base.

[0021] By adopting the above technical solution, auxiliary limit blocks are used to connect with auxiliary limit screws.

[0022] In a preferred embodiment, an auxiliary limiting screw is rotatably inserted into the side surface of the auxiliary limiting block.

[0023] By adopting the above technical solution, the auxiliary limiting screw rotates inward to contact the tandem shaft and form a fixed angle, thus providing an auxiliary function.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0025] In this application, the backrest substrate serves as the substrate component of the chair back, used to drive the chair back to flip, forming a simple chair structure with the seat. The backrest substrates are connected mainly through a plug-in connection between the plug shaft and the connecting upright plate, connecting the backrest substrates in series, thus creating a certain degree of flipping effect.

[0026] Then, a sliding damping shaft on the rotating groove serves as a blocking component, its movement throughout the assembly allowing it to contact subsequent damping components. The damping component primarily utilizes a damping base, which is slotted with a U-shaped upper end. A reset plate within the base has a spring structure at its bottom for resetting. Connecting bolts are used for installation; it is installed when needed and removed when not in use. Anti-detachment rings inserted into the side surface of the plug-in shaft prevent detachment. Finally, the seat serves as the chair's seating component for the user to sit on. Attached Figure Description

The backrest base plate 1 is connected mainly through the insertion of the insertion shaft 2 and the connecting upright plate 3, which connects the backrest base plates 1 together, creating a certain degree of flipping effect.

[0037] Then, the sliding damping shaft 5 on the rotating slide 4 serves as a blocking component, using its movement throughout the assembly to contact subsequent damping components. The damping component primarily utilizes a damping base 6, which is slotted with a U-shaped upper end. A reset spring plate 7 is installed inside, with a spring structure at its bottom for reset. Connecting bolts 8 are used for installation; it is installed when needed and removed when not in use. An anti-detachment ring 9, inserted into the side surface of the plug shaft 2, serves as a component to prevent detachment. Finally, the seat 10 serves as the chair's seat for the user to sit on.
