Description

Technical Field

[0001] The utility model relates to the field of children's dining chair structures. Background Art

[0002] With the enrichment of lifestyles, in addition to home life, outdoor activities and holiday travel have also become important parts of family life. Families with young children especially need multi-purpose dining chairs to provide dining conditions for children. The market needs children's dining chairs that can be suitable for both home use and outdoor use, and have good storage functions, so as to avoid waste caused by repeated purchases. Content of the Utility Model

[0003] In order to meet market demands, the utility model provides a children's dining chair structure, which has a simple structure, good storage performance, and strong versatility. It can be used at home and can also be carried outdoors, avoiding waste caused by repeated purchases.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a children's dining chair structure, including a chair body that can be opened or folded, a support rod group that constitutes the chair body, and a connecting rod connected to the support rod group. It is characterized in that: the support rod group has a meal board rod and a seat rod, the chair body is provided with at least one meal board rod and at least one seat rod, the seat rod is connected with a sliding seat, one end of the connecting rod is hinged to the meal board rod, the other end of the connecting rod is hinged to the sliding seat of the seat rod, the sliding seat slides along the seat rod, and the chair body is provided with a locking device that restricts or does not restrict the sliding of the sliding seat;

[0005] When the chair body is opened, the locking device restricts the sliding of the sliding seat, and the meal board rod and the seat rod move away from each other; when the chair body is folded, the locking device does not restrict the sliding of the sliding seat, and the meal board rod and the seat rod move closer to each other.

[0006] Its technical effects are as follows:

[0007] 1. When the chair body is in use, the seat rod and the meal board rod move away from each other, and the chair body as a whole opens. In order to keep the chair body as a whole stable, the locking device restricts the sliding of the sliding seat.

[0008] 2. When the chair body is not in use, the locking device does not restrict the sliding of the sliding seat, the seat rod and the meal board rod move closer to each other, and the chair body as a whole folds, which can be stored to save space.

[0009] 3. The chair body has good stability and storage performance, is suitable for home or outdoor use, has strong versatility, and avoids waste caused by repeated purchases.

[0010] Furthermore, the meal board rod and the seat rod are arranged vertically opposite to each other. The meal board rod has a first meal board rod and a second meal board rod, and the seat rod has a first seat rod and a second seat rod.

[0011] Its technical effect: By providing two dining board rods and two seat rods on the chair body, the overall stability of the chair body can be improved.

[0012] Further, the connecting rods include longitudinal connecting rods and transverse connecting rods. There are two intersecting transverse connecting rods at the front and rear of the chair body, and two intersecting longitudinal connecting rods at the left and right sides of the chair body. The joints at both ends of the connecting rods are all connected by hinges, and the intersection points of the two connecting rods are also connected by hinges.

[0013] Its technical effect: By using hinges for connection at multiple places of the connecting rods, the chair body can achieve opening or closing movement.

[0014] Further, the support rod group is a straight rod. The sliding seat is placed in the middle section of the seat rod and can slide up or down. A fixed seat is provided in the middle section of the dining board rod, and a base is installed at the lower end of the support rod group.

[0015] Its technical effect:

[0016] 1. Since the support rod group is a straight rod, the overall stability is maintained when the sliding seat slides along the seat rod.

[0017] 2. The base can enhance the stability of the support rod group.

[0018] Further, when the chair body opens, the sliding seat moves downward along the seat rod; when the chair body closes, the sliding seat moves upward along the seat rod.

[0019] Further, the first dining board rod is placed at the front side of the left part of the chair body, and the first seat rod is placed at the rear side of the left part of the chair body;

[0020] The fixed seat of the first dining board rod and the base of the first seat rod are connected by a longitudinal connecting rod on the left part of the chair body;

[0021] The base of the first dining board rod and the sliding seat of the first seat rod are connected by another longitudinal connecting rod on the left part of the chair body.

[0022] Further, the second dining board rod is placed at the front side of the right part of the chair body, and the second seat rod is placed at the rear side of the right part of the chair body;

[0023] The fixed seat of the second dining board rod and the base of the second seat rod are connected by a longitudinal connecting rod on the right part of the chair body;

[0024] The base of the second dining board rod and the sliding seat of the second seat rod are connected by another longitudinal connecting rod on the right part of the chair body.

[0025] Its technical effect: The dining board rods and seat rods on the left and right parts of the chair body are connected by longitudinal connecting rods on both sides, which is an important part for the overall synchronous movement of the chair body.

[0026] Further, the fixing seat of the first meal plate rod and the base of the second meal plate rod are connected by a horizontal connecting rod at the front of the chair body;

[0027] The base of the first meal plate rod and the fixing seat of the second meal plate rod are connected by another horizontal connecting rod at the front of the chair body.

[0028] Further, the sliding seat of the first seating rod and the base of the second seating rod are connected by a horizontal connecting rod at the rear of the chair body;

[0029] The base of the first seating rod and the sliding seat of the second seating rod are connected by another horizontal connecting rod at the rear of the chair body.

[0030] Its technical effect: The sliding seats of the two seating rods cooperate with the horizontal connecting rod to connect the two meal plate rods and the two seating rods to each other, and the whole chair body can move synchronously.

[0031] Further, the locking device is placed at the rear of the sliding seat of the seating rod. There is a locking end on the upper side of the locking device. The locking end faces the rear wall surface of the seating rod. The rear wall surface of the seating rod is provided with a locking hole. The lower side of the locking device is a button. The button tilts backward along the main body of the locking device. There is a fulcrum end in the middle of the locking device. The locking device is installed and connected to the sliding seat through the fulcrum end. The locking end and the button make a seesaw-like movement with the fulcrum end as the fulcrum, and the locking end of the locking device enters or disengages from the locking hole.

[0032] Its technical effect: When the locking end enters the locking hole, the sliding seat of the seating rod cannot slide. Under the linkage effect, the sliding seat of the meal plate rod cannot slide either; when the locking end disengages from the locking hole, the sliding seat can slide.

[0033] Further, the chair body is provided with a meal plate and a seating cover. The upper end of the meal plate rod is installed with or without a meal plate; the seating cover is installed with or without between the meal plate rod and the seating rod.

[0034] Its technical effect: The meal plate and the seating cover can be assembled or disassembled from the chair body at any time, which is convenient for daily storage and cleaning.

[0035] Each of the above further is an example. Each example can be used as an independent embodiment alone, or on the premise of ensuring no contradiction, any combination of each example can form a combined embodiment. BRIEF DESCRIPTION OF THE DRAWINGS
