Detailed ways

The features of the utility model can be clearly understood with reference to the detailed descriptions of the drawings and the embodiments.

Referring to Fig. 1, the utility model is a one-handed back adjustment structure of a rocking chair, including:

An underframe 1, the bottom of which is arc-shaped rather than horizontal, so the utility model can be shaken back and forth in situ, and a front support frame 11 and a rear support frame 12 are additionally provided front and rear; on the bottom frame 1 , and combine the fixed frame on the bottom frame 1 with a rivet 13 . Referring to Fig. 2, the fixed frame 2 is composed of a fixed frame base 21 and a fixed cover 22, the fixed frame base 21 has a plurality of fixed slots 211, the fixed cover 22 has an opening 221, and the opening The profile shape of 221 is identical with the shape of fixing slot 211; A back support 3, shape is a U font, offers a long slot 31 (with reference to Fig. 3) respectively at the two ends of U word opening top, and this back support 3 A moving part 32 with an opening 321 and a spring 322 (refer to FIG. 4A ) are respectively arranged inside both ends; an adjustment bracket 4 (refer to FIGS. 1 , 3 and 4A ), and an adjustment cross bar 41 is formed at its two ends After passing through the elongated slot 31 of the rear bracket 3, the opening 321 of the moving part 32, and the opening 221 of the fixed cover 22, the adjusting cross bar 41 is engaged with the fixing slot 211 in the fixing frame seat 21, and the adjusting The cross bar 41 is against one end of the spring 322 inside the moving part 32; a fixing clip 5 (referring to Fig. 3 and Fig. 4A), after the fixing clip 5 clamps the rear bracket 3 and the adjusting bracket 4, at this time The adjusting bracket 4 can radially move inside the fixing clip 5 , and then a fixing rivet 51 passes through the rear bracket 3 and abuts against the other end of the spring 322 inside the rear bracket 3 (refer to FIG. 4A ).

Next, the actuation situation when the utility model is used is described. First referring to Fig. 1, it is a state diagram when the rear support 3 of the present invention is horizontal, at this moment, the adjusting cross bar 41 of the adjusting support 4 is engaged with the first fixing groove 2111 of the fixing frame seat 21 in Fig. 2 , That is position A. When the user wants to stand up the rear bracket 3, the user only needs to hold the U-shaped bottom of the rear bracket 3 and lift it upwards, then the first fixing slot 2111 to the second fixing slot 2112 The outline of the boundary is a relatively circular shape, so the adjustment cross bar 41 will move along the boundary outline of the first fixing slot 2111 to the second fixing slot 2112, that is, it will move from position A to position B, and finally move to Position C is engaged with the second fixing slot 2112, and at the same time, the adjustment bar 41 will gradually move upward from the state shown in Figure 4A to the state shown in Figure 4B until it moves from position B to position C, and the adjustment The crossbar 41 will return to the state shown in FIG. 4A due to the rebounding force of the spring 322 , and the adjustment crossbar 41 will engage with the second fixing slot 2112 . In the present invention, the number of the plurality of fixing slots 211 is four, so the user can make the rear bracket 3 have four different height changes, which means that the adjusting crossbar 41 is respectively engaged with the first fixing slots 2111 , the second fixing slot 2112 , the third fixing slot 2113 and the fourth fixing slot 2114 , the actuation methods are the same as the aforesaid actuation methods. Referring to FIG. 5 , it is a state diagram when the adjusting crossbar 41 is engaged with the fourth fixing slot 2114 , it is located at position D, and the rear support 3 is at the highest height.

Conversely, when the utility model is in the state of Fig. 5, and the user wants to return the rear bracket 3 to a lower state, the user can pull the adjustment bracket 4 in Fig. 5 toward the direction of the rear bracket 3 with one hand, Then the adjustment crossbar 41 is changed from the state of FIG. 4A to the state of FIG. 4B in the same way. At this time, the adjustment crossbar 41 will move from the position D in FIG. Pulling in the direction of the ground, the adjusting cross bar 41 will move from position E to position F, and then after the user releases the previously pulled adjusting bracket 4, the adjusting cross bar 41 will change from the state of Fig. 4B to the state of Fig. 4A, and At the same time, it will move from the position F in FIG. 2 to the position G, which means that the adjusting cross bar 41 will move from the fourth fixing slot 2114 to engage with the third fixing slot 2113 . In the same way, when the rear bracket 3 is to be returned to the state shown in Fig. 1, the operation steps are the same as those described above, as long as the adjustment crossbar 41 is moved from position D to position E, and then the rear bracket 3 is pulled toward the ground direction by a large margin, so that Adjust the crossbar 41 to move from position E to position H, and finally return to position A.

The above-mentioned are only used to explain the preferred embodiments of the present utility model, and are not intended to limit the utility model in any form. Modifications or changes should still be included in the intended protection category of the utility model.
