[0022] The following further describes the present utility model in detail in conjunction with the embodiments and the attached drawings.

[0023] This embodiment provides a portable child safety seat, which includes a base 1. Refer to Figure 1 、 2 As shown, two or three sets of pulley assemblies 2 are connected to the bottom of the base 1. A storage groove 11 capable of storing the pulley assemblies 2 is provided at the bottom of the base 1. Each set of pulley assemblies 2 corresponds to a storage groove 11. Each set of pulley assemblies 2 is rotatably connected to the base 1 and has a retracted position where it is completely embedded in the corresponding storage groove 11 of the base and an extended position where it protrudes from the bottom plane of the base 1 after extending from the corresponding storage groove 11 of the base. Each set of pulley assemblies 2 is positioned at the extended position and the retracted position through a positioning mechanism.

[0024] In this embodiment, the structure of each set of pulley assemblies 2 is the same and each includes:

[0025] An installation bracket 21, which is fixed at the storage groove 11 of the base; the installation bracket 21 includes a U-shaped frame body 211. The U-shaped body in the middle of the frame body 211 is located inside the storage groove 11. The two sides of the frame body 211 extend outward to form installation lugs 212. The two installation lugs 212 on both sides are attached to and fixed to the base at the edge of the storage groove 11 opening. Symmetrically arranged arc-shaped sliding holes 213 are provided on the arms on both sides of the frame body 211. The arc-shaped sliding holes 213 are circular arcs, and the central angle of the arc is 90 degrees;

[0026] A pulley bracket 22, one end of the pulley bracket 22 is provided with a pulley installation groove, and the other end of the pulley bracket 22 is rotatably connected to the installation bracket 21 through a first rotating shaft 24; in this embodiment, the two ends of the first rotating shaft 24 are respectively movably inserted into the arc-shaped sliding holes 213 on the arms on both sides of the frame body;

[0027] A pulley 23, which is rotatably connected to the pulley installation groove of the pulley bracket through a second rotating shaft 25.

[0028] The positioning mechanism includes: a first positioning hole 214 provided on the arms on both sides of the frame body and communicating with the first end of the arc-shaped sliding hole 213, and a second positioning hole 215 provided on the arms on both sides of the frame body and communicating with the second end of the arc-shaped sliding hole. The first positioning hole 214 is vertically arranged, and the second positioning hole 215 is horizontally arranged; when the two ends of the first rotating shaft 24 are respectively stuck into the first positioning holes 214, the pulley assembly is positioned at the extended position. Refer to Figure 3 、 5 , and when the two ends of the first rotating shaft 24 are respectively stuck into the second positioning holes 215, the pulley assembly is positioned at the retracted position. Refer to Figure 4 、 5 As shown.

[0029] In this embodiment, a chute 221 is formed in the pulley bracket 22. A slider 26 is movably arranged in the chute 221. The first rotating shaft 24 is fixedly connected to the slider 26. Slide holes 222 for both ends of the first rotating shaft 24 to pass through are formed in the side wall of the chute 221. A return spring 27 acting on the slider 26 is further arranged in the chute 221. An opening groove 261 is formed in the outer side surface of the slider 26. During use, a finger is inserted into the opening groove 261 of the slider 26 to move the slider 26 along the chute 221 on the pulley bracket 22. The first rotating shaft 24 moves in the arc-shaped sliding hole 213 along with the slider 26. When both ends of the first rotating shaft 24 are respectively clamped into the first positioning holes 214, the pulley assembly 2 is positioned at the deployed position. By continuously moving the slider 26 to make the first rotating shaft 24 disengage from the first positioning holes 214 along with the slider 26 and then applying a force on the pulley assembly, the first rotating shaft 24 moves in the arc-shaped sliding hole 213. When both ends of the first rotating shaft 24 are respectively clamped into the second positioning holes 215, the pulley assembly is positioned at the retracted position. The return spring 27 acts on the slider 26, enabling the slider 26 and the pulley assembly 2 to maintain the positioned state when positioned at the deployed position and the retracted position.
