Abstract
Description
Technical Field
[0001] This utility model relates to the field of child car seat technology, specifically an anti-tipping child car seat. Background Technology
[0002] Hospital child chairs are medical furniture specifically designed for children's medical settings, combining practicality with humanistic care. Their core function focuses on improving children's experience during IV infusions and waiting times. For example, they employ ergonomic design and feature height-adjustable IV poles to accommodate children of different ages. In terms of materials, the main frame typically uses a metal skeleton with high-density foam filling, and the surface is covered with soft leather or fabric, ensuring both long-term comfort and ease of disinfection and cleaning.
[0003] Utility model CN216220968U discloses a child seat with anti-tipping function, including a base. Fixing holes are provided at the front and rear ends of the left side of the top of the base. Fixing cavities are provided on the front and rear sides of the inner cavity of the base. Each fixing cavity has a sliding component, the top of which extends to the top of the base. A movable plate is provided at the top of each sliding component, and a seat is positioned at the top of the two movable plates. A fixing box is located at the center of the top of the base. A fixing component is provided inside the fixing box, with its bottom end extending to the front and rear sides of the fixing cavity and connecting to the two sliding components respectively. This child seat with anti-tipping function solves the problem of child seats frequently tipping over during actual use, leading to falls and injuries to children.
[0004] Because children encompass a wide age range, including older children who can behave normally and cooperate while sitting in a chair to perform medical procedures, as well as younger children who have difficulty acting independently, anti-tipping measures are usually required for younger children. Although the aforementioned utility model can prevent tipping, its structure is relatively complex and occupies a large area, making it unsuitable for medical settings with limited space. Furthermore, for older children, the seat cannot be quickly and freely adjusted during use, causing inconvenience. In addition, since the seat in the prior art does not have an anti-tipping structure, some younger children may fall off the seat due to instability and tilting. Therefore, to address the above issues, an anti-tipping child seat is proposed. Utility Model Content
[0005] To address the technical problems of child car seats in comparative technologies, such as complex structures, large footprints, unsuitability for medical settings, unsuitability for older children, and lack of lateral support, which could lead to younger children easily falling off and getting injured, this utility model provides an anti-tipping child car seat.
[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0007] An anti-tipping child seat includes a seat body with four symmetrically arranged inclined support legs fixedly connected to its lower end surface. The two front inclined support legs extend forward, and the two rear inclined support legs extend backward. A lateral support member is installed at the bottom of the inclined support legs to provide lateral support, preventing the seat body from tilting. A fall arrestor is rotatably mounted on the seat body and provides lateral support to a child sitting on the seat body when it is rotated down. The lateral support member includes a corner restraint frame fixedly connected to the inclined support legs and a rotating support rod rotatably connected to the inclined support legs. The corner restraint frame and the rotating support rod are connected by a locking mechanism.
[0008] In one possible implementation, the inclined support leg includes a support body with a vertically arranged support shaft fixedly connected to its bottom end, and a support foot threadedly connected to the bottom end of the support shaft.
[0009] In one possible implementation, the rotating support rod includes a rotating cylinder rotatably connected to a support shaft, on which a support rod body is fixedly connected, and the end of the support rod body is machined to form a ground-contacting round head.
[0010] In one possible implementation, the corner constraint frame includes a sector-shaped frame fixedly connected to the support shaft, on which a through constraint groove is formed; the locking mechanism includes a mating rod fixedly connected to the rotating cylinder, on which a sliding shaft that slides in the constraint groove is fixedly connected, and a locking wheel is threadedly connected to the top of the sliding shaft.
[0011] In one possible implementation, the sector angle of the sector frame is 100 degrees, and when the sliding shaft slides from the beginning end of the constraint groove to the end end, the rotating cylinder rotates by an angle of 100 degrees.
[0012] In one possible implementation, the fall arrestor includes two symmetrically arranged armrests that are rotatably connected to the seat body. The ends of the armrests are connected as one unit by a front baffle, and a centrally arranged support rod is fixedly provided on the lower end face of the front baffle, with its bottom end contacting the seat body.
[0013] In one possible implementation, the bottom end of the support rod is fixedly provided with an adsorption end; the seat body is provided with an end slot corresponding to the adsorption end, wherein a fixing magnetic sheet for adsorbing and fixing the adsorption end is embedded.
[0014] In one possible implementation, the seat body includes a seat frame on which a seat cushion and a backrest are laid. The seat frame has mounting holes, and the seat cushion and backrest are provided with insertion shafts corresponding to the mounting holes. The seat cushion and backrest have the same structure, both including a base plate on which a flexible pad is adhered.
[0015] In summary, this utility model has the following beneficial technical effects:
[0016] Because the two sets of inclined support legs are angled forward and backward respectively, the main body of the seat has a strong anti-tipping ability in the front and back directions. In the left and right directions, there are rotatable lateral support members at the bottom of the inclined support legs. When the main body of the seat needs lateral support, the support rod is rotated to open and extend to the side, and is fixed at the maximum opening angle by the corner constraint frame and locking mechanism to achieve the best anti-tipping effect. When lateral support is not needed, the support rod can be rotated inward to avoid taking up too much space, and the main body of the seat can be used as a normal chair.
[0017] In addition, the main body of the seat is equipped with a rotatable anti-fall restraint frame. When a young child sits on the main body of the seat, the anti-fall restraint frame can be lowered to integrate with the main body of the seat, forming a stable support frame that provides lateral support for the young child and prevents the child from falling and getting injured due to instability in the center of gravity.

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0026] like Figure 1 - Figure 3 As shown, this embodiment provides an anti-tipping child seat, including a seat body 1, with four symmetrically arranged inclined support legs 2 fixedly connected to its lower end surface. The two front inclined support legs 2 extend forward, and the two rear inclined support legs 2 extend backward. A lateral support member 3 is installed at the bottom of the inclined support legs 2 to provide lateral support, preventing the seat body 1 from tilting to the side. An anti-fall restraint frame 4 is rotatably installed on the seat body 1. When it rotates down, it becomes integrated with the seat body 1 to form a stable support frame, providing lateral support for young children and preventing them from falling and getting injured due to instability and tilting on the seat body 1.
[0027] The lateral support 3 includes a corner constraint frame 31 fixedly connected to the inclined support leg 2, and a rotating support rod 32 rotatably connected to the inclined support leg 2. The corner constraint frame 31 and the rotating support rod 32 are connected by a locking mechanism 33. When the seat body 1 needs lateral support, the rotating support rod 32 is rotated to open and extend to the side, and is fixed at the maximum opening angle by the corner constraint frame 31 and the locking mechanism 33, so as to achieve the best anti-tilting effect. When lateral support is not needed, the rotating support rod 32 can be rotated inward without taking up too much space, and the seat body 1 can be used as a normal chair.
[0028] The inclined support leg 2 includes a support body 21, the bottom end of which is fixedly connected to a vertically arranged support shaft 22. A support foot 23 is threadedly connected to the bottom end of the support shaft 22. Figure 3 As shown, the above-mentioned structural form provides the necessary structural foundation for the overall installation and operation of the lateral support 3.
[0029] Based on the aforementioned structural form of the inclined support leg 2, the rotating support rod 32 includes a rotating cylinder 321 rotatably connected to the support shaft 22, on which a support rod body 322 is fixedly connected. The end of the support rod body 322 is machined to form a ground-contacting round head. Figure 3 As shown; since the rotating cylinder 321 can rotate freely, the support rod body 322 can be contracted and expanded by rotation to meet different usage needs. When tilting occurs, the ground-contacting round head of the support rod body 322 will directly contact the ground to provide support force and prevent the seat body 1 from tilting further.
[0030] In the above technical solution, since the rotating cylinder 321 cannot be constrained and fixed, even if the main body 322 of the support rod is in the open state, it is easy to rotate and retract under the action of external force and lose the anti-tilting function. Therefore, the corner constraint frame 31 and the locking mechanism 33 need to work together. The corner constraint frame 31 includes a fan-shaped frame 311 fixedly connected to the support shaft 22, which has a through constraint groove 312. The locking mechanism 33 includes a mating rod 331 fixedly connected to the rotating cylinder 321, which has a sliding shaft 332 fixedly connected to it and sliding in the constraint groove 312. The top of the sliding shaft 332 is threaded with a locking wheel 333. When the locking wheel 333 is tightened, it can fix the mating rod 331 through the friction between it and the fan-shaped frame 311, so that the rotating cylinder 321 cannot rotate freely. Thus, it can be fixed when the main body of the support rod 322 is fully retracted or fully opened, which is convenient for use.
[0031] The sector angle of the sector frame 311 is 100 degrees. When the sliding shaft 332 slides from the starting end to the ending end of the constraint groove 312, the rotating cylinder 321 rotates by an angle of 100 degrees. Figure 3 As shown; if the rotatable angle of the rotating cylinder 321 is 90 degrees, when the main body of the support rod 322 is fully open, it will be completely perpendicular to the side. Under the action of force in this state, the main body of the support rod 322 may have a tendency to rotate back and retract due to the eccentricity of the force, and may even overcome the locking effect of the locking wheel 333 and retract, causing its anti-tipping function to fail. However, when the rotation angle of the rotating cylinder 321 is 100 degrees, when the main body of the support rod 322 is fully open, it will present an oblique forward or oblique backward posture. Under the action of force, the main body of the support rod 322 will not have a tendency to rotate back, but will only fit tightly with the end of the constraint groove 312, and will not cause the anti-tipping function to fail.
[0032] like Figure 4As shown, the fall arrestor 4 includes two symmetrically arranged armrests 41 that are rotatably connected to the seat body 1. The ends of the armrests 41 are connected as one unit by a front baffle 42. A centrally arranged support rod 43 is fixedly installed on the lower end face of the front baffle 42, and its bottom end contacts the seat body 1, making it integrated with the seat body 1 to form a stable support frame. This provides lateral support for young children and prevents them from falling and getting injured due to instability on the seat body 1. The bottom end of the support rod 43 is fixedly provided with an adsorption end 46. The seat body 1 has an end slot 44 corresponding to the adsorption end 46, in which a fixing magnetic sheet 45 is embedded for adsorbing and fixing the adsorption end 46. Based on the above technical solution, after the bottom end of the support rod 43 contacts the seat body 1, the adsorption end 46 can be adsorbed by the fixing magnetic sheet 45 to achieve a fixed connection between the support rod 43 and the seat body 1.
[0033] like Figure 5 As shown, the main body of the seat 1 includes a chair frame 11, on which a seat cushion and a backrest are laid. The chair frame 11 has mounting holes 12, and the seat cushion and backrest are provided with insertion shafts 13 corresponding to the mounting holes 12. The seat cushion and backrest have the same structure, both including a base plate 14 on which a flexible pad 15 is glued. The above technical solution can realize the quick connection between the seat cushion and the backrest and the chair frame 11, which is convenient for cleaning and replacing the seat cushion and backrest.
[0034] The working principle and usage process of this utility model:
[0035] When the seat body 1 needs lateral support, the rotating support rod 32 is rotated to open and extend to the side, and is fixed at the maximum opening angle through the corner constraint bracket 31 and the locking mechanism 33, achieving the best anti-tilting effect. When lateral support is not needed, the rotating support rod 32 can be rotated inward to avoid taking up too much space, and the seat body 1 can be used as a normal chair.
[0036] Since the rotating cylinder 321 has a rotation angle of 100 degrees, when the support rod body 322 is fully opened, it will be in a forward or backward position. When subjected to force, the support rod body 322 will not rotate back, but will only fit tightly with the end of the constraint groove 312, and will not cause the anti-tipping function to fail.
[0037] In addition, when a young child sits on the seat body 1, the fall arrestor 4 can be lowered to connect with the seat body 1 to form a stable support frame, which provides lateral support for the young child and prevents the young child from falling and getting injured due to instability and tilting on the seat body 1.
[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
