The tongue portion 152 is extended downwardly from the cover body 13 and a latching flange 丨 54 is protruded outwardly from the tongue portion 152. It extends radially from the pivot axis γ. The first coupling member ΐΐ7 ΐΐ 156 ° because the tongue portion 152 extends downwardly from the cover body 132 into a cantilever structure. Therefore, the cantilever structure passing through the tongue portion 152 has a spring force of 201221090 at the pivot axis γ, and the engaging flange 154 is slidable. Closing or disengaging the opening 156 (see Figure 7). When the latching member 150 is engaged with the hole 156, the engaging flange 154 can abut against the edge of the hole 156 such that the first coupling member 117 is lockedly coupled to the second coupling member 124. As shown in Fig. 5, the sleeve 130 has a lower end portion 13 and a lower end portion 130C and an upper end portion 130A are respectively located on opposite sides of the sleeve 130, and the lower end portion 130C is provided with two opposite and spaced apart sleeves. The barrel flange 158 (only one of which is shown in Figure 5)' and the two sleeve flanges 158 are in different radial positions, respectively. When the seat frame 1〇4 connected to the base 1〇2 rotates and drives the sleeve 13〇, the any-sleeve flange 158 can abut against the anchoring member in the groove 112 (as shown in FIG. 6). 'To limit the maximum angle of rotation of the seat frame 104. Fig. 6 is an enlarged schematic view showing the internal structure of the recess 112 in the green base. The side wall ιι of the groove 112 is approximately cylindrical. A bump 162 that can be coupled to the lock 134 and prevents the rotation of the lock is splayed by the bottom surface ία P of the recess 112. A cushion 164 is fixed to the bottom surface 112A, and the cushion is located in the opposite position in the recess 112. The cushion (6) is between the flanges 158. When the sleeve flange 158 abuts against the elasticity of the material of the cushioning buffer 164, the two sets can be buffered (when the first side is slow, the buffer 塾16: will:] J== The chair frame 104 can be used for generating a magazine relative to the buffer (4) 4, and performing a reciprocating rotation action, thereby enabling the child to perform a demonstration operation of the seat structure 100, and then refer to FIG. 7 for description. Will be the first to engage the second member of the m-parts 124, so that the chair frame loses the connection to the bottom of the money f = 7 figure does not, with the first - engages the piece 117 sliding sleeve on the second face 124, the flash card can be engaged with the hole 156 of the first face piece 117 to lock the first coupling member 117 and the coupling member 124 to each other, so that the seat frame 1〇4 and the bottom=fixed. The handle 148 is inserted into the slot 119 of the first cover member 117_, and the sleeve 140 is combined with the slot 119. The member 117 and the second engaging member 124 can further interact with each other. If the user needs to rotate the seat frame 1〇4, the rotation lock 134 should be moved along the direction away from the base 1〇2 until the hook portion 146 of the rotation lock 134 passes through itself. a spring hook, the second _24 is fixed at a higher position from the rib 147 of the sleeve 130 (e.g., the second position indicated by the solid line in Fig. 7). When the brake lock 134 is in this position The restricting flange 142 of the turn lock 134 is located in the gap above the bump 162 so as to be disengaged from the limitation of the bump 162. The person 104 rotates relative to the base 102 so that the locking member 124 can be pivoted The shaft 122 rotates in the same direction. The handle 148 is in contact with the slot 119 of the first coupling member ι17, and the engaging flange 154 abuts against the hole 156, so that the first coupling member 117 124 'The rotation of the seat frame 1〇4 relative to the base can be transmitted from the first coupling member 117 to the second coupling member 124. If the user wants to lock the seat frame 1 (10) to the base 1〇2, the chair frame 1〇 first 4 must be in a position that allows the handle 148 to be aligned with the projection 162. The user pulls the handle 148 down so that the hook 146 is disengaged from the rib 147, causing the tactile lock 134 to slide down to a lower position. Position (eg, item 7, above I position), and the bump 162 snaps to the limiting flange = , = 144: when the shackle 134 is here In time, the position π of the two limiting flanges 142 is close to the two opposite side walls of the bump 162. Therefore, as long as any one of the limiting flanges 142 abuts the bumps 162, the second coupling member, the younger one - The turning member 117' and the seat frame locked with the first engaging member 117 are rotated, and the method 201221090 rotates relative to the pivot axis γ. § When the user does not use the seat structure 100, the user can push the flash lock 150 The snap flange 154 causes the tongue 152 to flex inwardly to disassemble the seat structure 1〇〇. Therefore, when the engaging flange 154 moves in the radial direction of the pivot 122 and disengages from the hole 156', the first coupling member 117 and the second coupling member 124 release the locking connection with each other. Then, the seat frame and the second fitting 117 fixed to the seat frame can be pulled up to disengage the seat frame 1〇4 and the first facing member 117 from the base 1〇2 and the splicing assembly 106. Thereby, the seat frame 1〇4 and the base 1〇2 can be separately stored. The seat structure and the assembling method thereof provided by the invention have at least the following advantages: The seat frame can be conveniently assembled to the base or removed from the base. In this way, the chair frame can be closely packed, thus reducing the space for the seat structure. In addition, when the seat frame is connected to the base, the specific structural design can drive the rotation of the frame and prevent the rotation of the frame, so that the seat is safer to use.
