A retracting device is respectively installed between the upper ends of the left foot bar and the upper end of the right foot bar of the rear leg;

Each folding device includes a rear case cover, the rear case cover includes a base plate, the periphery of the base plate extends vertically to form a surrounding plate, and the surrounding plate is provided with an unfolding through hole and a folding through hole that are staggered from each other, and the base plate extends with A sleeve that can be fixed to the corresponding leg of the rear leg;

The rear cover is nested and pivotally connected with a front cover that can rotate relative to the rear cover. The front cover includes a base plate, and the periphery of the base plate extends vertically to form an end plate near the inner side of the rear cover. There is a through hole on the top, and the base plate is extended with a sleeve that can be fixed to the corresponding leg of the front leg;

A switch button is installed on the front cover. The switch button includes a pressing part and a stop part extending from the pressing part and extending into the inside of the front cover. The pressing part can extend out of the through hole of the front cover and the back cover One of the through holes; the front case cover is equipped with an elastic element that can make the stop part of the switch button lean against the inner side of the end plate of the front case cover.

Wherein: the end plate of the front cover extends vertically to the inside of the front cover with two parallel side plates, the side plates and the base plate are enclosed to form an accommodating space for the stop portion of the switch button, and the space between the side plates is A baffle is further embedded, and the elastic element is placed between the baffle and the stop portion of the switch button.

In conjunction with accompanying drawing and embodiment, structural feature of the present utility model is described in detail as follows:

Brief description of the drawings:

Fig. 4 is a side view of the folded state of the embodiment of the utility model installed on the children's dining chair.

As shown in Figure 1, the present embodiment is a foot frame folding device of a children's dining chair. The children's dining chair 1 includes a front foot frame 11 and a rear foot frame 12, the front foot frame 11 is fixedly provided with a seat 13, and the front foot frame 11 has an upright left foot bar 111 and an upright right foot bar 112 that are spaced apart from each other. A slightly U-shaped base 113 is connected between the left and right foot bars 111 and 112, and the left and right sides below the base 113 are respectively A runner 114 is housed, and the structure of rear foot frame 12 is identical with front foot frame 11, also comprises a left foot bar 121, a right foot bar 122, a base 123 and two runners 124, front and rear foot frame 11,12 A folding device 20 is installed between the two rod ends above the left foot rods 111, 121, and between the two rod ends above the two right foot rods 112, 122, because the two folding devices 20 have the same structure and are arranged symmetrically. Therefore, only the folding device 20 on the left side will be described in detail below.

As shown in Figure 2, the folding device 20 on the left side includes a rear case cover 3, a front case cover 4, a switch button 5 and an elastic element 6; wherein: the rear case cover 3 includes a circular base plate 31, the base plate The center of 31 is provided with a shaft hole 311, and the outer peripheral edge of the board of the base plate 31 extends vertically to form an arc-shaped enclosure 32, and the enclosure 32 is provided with a mutually staggered expansion through-hole 321 and a collection through-hole 322, and the enclosure The plate body of 32 has a hollow sleeve 33 that can be socketed and fixed with the left foot bar 121 of the rear foot frame 12 and extends obliquely to the rear and downward.

The front case cover 4 can be covered with the rear case cover 3 correspondingly, and it includes a circular base plate 41, and a shaft hole 411 is provided in the center of the base plate 41. A groove 42 is formed at the top with an opening facing upward and below the enclosure plate 32 of the rear case cover 3. The bottom side of the groove 42 is an arc-shaped end plate 43, and the center of the end plate 43 is provided with a through hole 431. The bottom end of 43 extends vertically downwards with two parallel side plates 44, and these side plates 44 and the base plate 41 enclose an accommodation space 45, and a horizontal baffle plate 46 is embedded near the bottom of the accommodation space 45, the baffle plate A stud 461 protrudes upward from the center of 46; the base plate 41 extends obliquely forward and downward, and has a hollow sleeve 47 that can be socketed and fixed with the left foot bar 111 of the front leg 11, between the front cover 4 and the rear cover 3 A hollow pivot 48 is used to connect the shaft holes 411, 311 of the front and rear case covers 4 and 3 at the same time, and then a rivet 49 is used to penetrate the pivot 48 and be riveted and pivotally connected to each other, so that the front case cover 4 can be pivoted by the pivot 48. The fulcrum rotates relative to the rear case cover 3 .

The switch button 5 is installed on the front case cover 4, and it includes a cylindrical pressing part 51 that can extend out of the through hole 431 of the front case cover 4 at the same time, and a cylindrical pressing part 51 that extends downward from the pressing part 51 and extends into the front case cover 4. The square stop portion 52 of the accommodating space 45, the stop portion 52 is larger than the through hole 431 of the front cover 4, and its bottom is recessed to form a receiving groove 521, and the top of the pressing portion 51 is arc-shaped; the front and rear legs 11, 12 When unfolding and standing, the above-mentioned pressing part 51 will pass through the unfolding through hole 321 of the rear case cover 3; Hole 322.

The elastic element 6 is a compression spring, one end of which is sleeved on the stud 461 of the baffle plate 46, and the other end extends into the cavity 521 against the switch button 5, and can make the top of the stopper 52 of the switch button 5 butt against the bottom side of the end plate 43 of the front case cover 4 .

As shown in FIGS. 3 and 4 , since the folding devices 20 on the left and right sides have the same structure and are operated separately by both hands at the same time, the following operation description only describes the folding device 20 on the left side. When the switch button 5 stretches out from the expansion through hole 321 of the rear case cover 3 to stop the relative rotation of the front and rear case covers 4 and 3, the lower ends of the front and rear legs 11 and 12 will be opened and erected. It is the normal use state of the children's dining chair 1; when the lower ends of the front and rear legs 11 and 12 are to be closed together after use, the pressing part 51 of the switch button 5 can be pressed away from the rear shell by overcoming the elastic force of the elastic element 6 Expand the through hole 321 of the cover 3, then lift the front leg 11 slightly backward, and use the gravity of the front leg 11 to make the front cover 4 and the front leg 11 rotate with the pivot 48 as the fulcrum, that is, the front leg 11 swings Rear stand 12, during the process, the top end of the pressing part 51 has been against the inner side of the panel 32 of the rear case cover 3, and when the pressing part 51 swings to correspond to the retractable through hole 322 of the rear case cover 3, the pressing part 51 immediately The elastic force of the elastic element 6 pops out through the retractable through hole 322 to stop the relative rotation of the front and rear shell covers 4 and 3. At this time, the front and rear legs 11 and 12 are close to each other and the folding is completed; , 12 When in use, as long as the hand presses the pressing part 51 and then reverses the operation, it can be completed.

If it is necessary to increase the expansion angles of the front and rear legs 11, 12, more than one through hole for the pressing part 51 to protrude can be added between the expansion through hole 321 and the retraction through hole 322, so that The deployment angles of the front and rear legs 11, 12 are adjusted in a multistage manner.

Compared with the prior art, the utility model has the following effects:

As can be seen from the above description, the utility model allows the user to easily close and close the opened legs with both hands after the children's dining chair is used up, which is convenient for operation, storage and carrying out .
