[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, the embodiment of the present invention provides a baby carriage fence device 1, comprising two railings 10 and a first connecting component 12 and a second connecting component 14 respectively fixed to opposite ends of a frame 3 and connected and fixed to the corresponding ends of the two railings 10. The first connecting component 12 comprises a first base 120 fixed relative to the frame 3 and a pivot shaft 122 fixed to the railing 10. The first base 120 is provided with a pivot hole 121, and the inner wall of one side of the pivot hole 121 is further recessed to form a storage cavity 1210. The storage cavity 1210 is provided with a first base 120 fixed relative to the frame 3 and a pivot shaft 122 fixed to the railing 10. A pressing block 124 and an elastic element 126 for pushing the pressing block 124 toward the middle of the pivot hole 121 are assembled in the cavity 1210; the pivot shaft 122 is fixed to the first end 10 of one of the railings 10 and is inserted into the pivot hole 121 from one end of the pivot hole 121 and is fixedly connected to the first end 10 of the other railing 10; the pressing block 124 is elastically pressed against the outer side of the pivot shaft 122 under the push of the elastic element 126 to limit the rotation of the pivot shaft 122.

[0027] In the embodiment, the first end of the rail 10 is assembled with the pivot shaft 122, a pivot hole 121 is formed on the first base 120 of the first connecting assembly 12 to correspond to the pivot shaft 122, and a receiving cavity 1210 is formed on one side of the pivot hole 121 to assemble the pressing block 124 and the elastic element 126. Under the action of the elastic element 126, the pressing block 124 is elastically pressed against the side surface of the pivot shaft 122, thereby playing a role of limiting the rotation of the pivot shaft 122 like a brake pad. When the rail 10 needs to be rotated, appropriate force needs to be applied to drive the pivot shaft 122 to slide relative to the pressing block 124 to realize rotation. Thus, when the overall height of the fence device 1 is adjusted, the one end of the rail is lifted and moved, and the other end can be correspondingly rotated within a certain range, thereby facilitating the step-by-step adjustment of the height of the stroller fence device 1. Moreover, when the corresponding end of the rail 10 is completely separated from the second connecting assembly 14, the rail 10 can also be conveniently rotated to the vertical position, thereby facilitating the entry and exit of children from the stroller.

[0028] In the specific implementation, the rail 10 is usually designed in a U shape and is symmetrically assembled on the left and right sides of the stroller.

[0029] In another optional embodiment of the utility model, as shown in Figure 4 the outer side surface of the pivot shaft 122 is provided with the first tooth pattern 1220 which is uniformly distributed in the circumferential direction and extends in the axial direction, and the side surface of the pressing block 124 facing the pivot shaft 122 is correspondingly provided with the second tooth pattern 1240 which is engaged with the first tooth pattern 124 (as shown in Figure 5 In the embodiment, the corresponding tooth patterns are designed between the pressing block 124 and the pivot shaft 122 to be engaged, which is beneficial to prevent the rotation of the pivot shaft 122 and to facilitate the rotation of the rail 10 by applying more force, thereby further improving the safety.

[0030] In an optional embodiment of the utility model, as shown in Figure 5 the side surface of the pressing block 124 facing the pivot shaft 122 is a concave arc surface, and the second tooth pattern 1240 is formed in the concave arc surface. In the embodiment, the side surface of the pressing block 124 facing the pivot shaft 122 is designed as a concave arc surface, and the second tooth pattern 1240 is formed in the concave arc surface, which can better match the outer side surface of the cylindrical pivot shaft 122, the contact surface is large, and it is beneficial to prevent the rotation of the pivot shaft 122 and to further improve the safety.

[0031] In an optional embodiment of the utility model, as shown in Figures 1 to 3As shown, the first end and the second end of the guardrail 10 are both provided with an adapter 100, the end of the adapter 100 forms a plug column 101, the plug column 101 is further provided with an elastic latch 102 protruding outward from the side surface of the plug column 101, the end surface of the pivot shaft 122 is provided with a plug hole 1222 and the corresponding side wall of the plug hole 1222 is provided with a latch hole 1224, the plug hole 1222 at the end of the pivot shaft 122 is plugged into the plug column 101 of the adapter 100 on the first end of one of the guardrails 10, and the elastic latch 102 on the plug column 101 is latched into the latch hole 1224 for positioning. In the embodiment, the adapters 100 are mounted on the two ends of the guardrail 10, and the end of the adapter forms the plug column 101 with the elastic latch 102, which is beneficial to improve the compatibility of the two ends of the guardrail 10 with other related components, and the pivot shaft 122 provided with the plug hole 1222 and the latch hole 1242 on the end surface can be plugged and fixed to the end of the plug column 101, which is convenient for assembling the related components.

[0032] In an optional embodiment of the utility model, the first connecting assembly 12 further includes the plug seat 128 corresponding to the plug column 101 end of the adapter 100 on the first end of another guardrail 10, the plug seat 128 is also provided with the plug hole 1280 for the plug column 101 to be inserted and the latch hole 1282 for the elastic latch 102 to be latched, the end surface of the plug seat 128 is also provided with the positioning hole 1284, the end of the pivot shaft 122 is provided with the positioning plug 1226 for being inserted into the positioning hole 1284, and the cross sections of the positioning hole 1284 and the positioning plug 1226 are matched and are both non-circular. In the embodiment, the plug seat 128 with the positioning hole 1284 is assembled on the plug column 101 end of the first end of another guardrail 10, and the positioning plug 1226 is arranged on the end of the pivot shaft 122 to be inserted into the positioning hole 1284, the cross sections of the positioning plug 1226 and the positioning hole 1284 are both designed as non-circular and matched, thereby achieving the coaxial fixed butt joint of the pivot shaft 122 and the plug seat 128, and the butt joint of the two guardrails 10, so that the synchronous rotation of the two guardrails 10 can be realized. It can be understood that, in the implementation and application process, when the guardrail 10 is adjusted, the guardrail 10 only needs to rotate in a small angle range, and the guardrail 10 does not need to be disassembled and assembled, which is beneficial to quickly adjust the guardrail 10.

[0033] In an optional embodiment of the present invention, a pivoting shaft 122 is sleeved and fixed to the end of each of the posts 101 of the adapter 100 at the first ends of the two railings 10. The ends of the pivoting shafts 122, respectively fixed to the first ends of the two railings 10, are inserted into the pivot holes 121 from opposite ends of the pivot holes 121. The ends of the two pivoting shafts 122 are respectively provided with positioning plugs 1226 and positioning holes (not shown) for mutual insertion. The cross-sections of the positioning plugs 1226 and the positioning holes are compatible and non-circular. In this embodiment, by sleeve-fixing a pivoting shaft 122 to the post 101 at the first end of the other railing 10, and providing the ends of the two pivoting shafts 122 with matching, non-circular positioning plugs 1226 and positioning holes, respectively, the two pivoting shafts 122 can be coaxially connected, thereby achieving the connection, fixation, and synchronous rotation of the two railings 10.
