[0004] Therefore, the utility model aims at providing a novel metal chair frame to solve the technical problem of the long length of the metal chair frame after folding.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a novel metal chair frame, including the plate body, the bottom of plate body is provided with cavity, and the four corners in the cavity are rotatably connected with first support column through hinged seat, the tail end of first support column is rotatably connected with second support column, one side of first support column is provided with second sliding slot, and the inside of second sliding slot is slidably connected with sliding plate, one side of second support column is provided with first sliding slot in communication with second sliding slot, both ends of sliding plate are rotatably connected with stud, and sliding plate and first sliding slot are mutually matched.
[0006] The utility model further sets up, both sides of first sliding slot and second sliding slot are provided with limit slot, both sides of sliding plate are provided with limit block matched with limit slot.
[0007] The utility model further sets up, one side of second support column is provided with insertion slot, both sides in the inside of insertion slot are provided with insertion block, and one side of insertion block is fixed with connecting rod.
[0008] The utility model further sets up, the cross section of insertion slot is cross-shaped, and the cross section of insertion block is convex-shaped.
[0009] The utility model further sets up, insertion slot penetrates second support column, and one side of two insertion blocks mutually abuts and touches.
[0010] The utility model further sets up, the tail end of stud penetrates sliding plate, and stud and first sliding slot and second sliding slot mutually contact.
[0011] Summarized above, the utility model mainly has following beneficial effects:
[0012] 1. This utility model uses a second support column to rotate and open the first support column, so that the first slide groove and the second slide groove are connected. Then, the slide plate is pulled and slid inside the first slide groove, so that the slide plate is located between the first slide groove and the second slide groove. Then, the two studs are rotated to complete the connection and fixation of the first support column and the second support column. The reverse operation is performed by turning the studs in the opposite direction to rotate and overlap the first support column and the second support column, and then rotate the first support column and the second support column into the cavity, reducing the overall length and making it easy to carry.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0019] The embodiments of this utility model will be described below based on its overall structure.
[0020] A new type of metal chair frame, such as Figures 1-4 As shown, the device includes a plate body 1. A cavity 7 is provided at the bottom of the plate body 1. A first support column 2 is rotatably connected to the four corners of the cavity 7 via a hinge seat. A second support column 3 is rotatably connected to the end of the first support column 2. A second slide groove 10 is provided on one side of the first support column 2. A slide plate 8 is slidably connected inside the second slide groove 10. A first slide groove 9 is provided on one side of the second support column 3 and communicates with the second slide groove 10. Both ends of the slide plate 8 are rotatably connected to studs 11. The slide plate 8 and the first slide groove 9 cooperate with each other.
[0021] The first support column 2 and the second support column 3 are rotated out of the cavity 7, then the second support column 3 is rotated, the first support column 2 and the second support column 3 are rotated apart, the first sliding groove 9 and the second sliding groove 10 are communicated, the sliding plate 8 is pulled into the first sliding groove 9 from the second sliding groove 10, the sliding plate 8 is located in the first sliding groove 9 and the second sliding groove 10, then the two studs 11 are rotated, and the connection between the first support column 2 and the second support column 3 is completed.
[0022] Please refer to Figure 4 The two sides of the first sliding groove 9 and the second sliding groove 10 are provided with limiting grooves, the two sides of the sliding plate 8 are provided with limiting blocks matched with the limiting grooves, the ends of the studs 11 penetrate the sliding plate 8, and the studs 11 are in contact with the first sliding groove 9 and the second sliding groove 10.
[0023] It can be understood that the limiting blocks and the limiting grooves are matched, the sliding plate 8 moves more stably in the first sliding groove 9 and the second sliding groove 10, the sliding plate 8 is prevented from being separated, the studs 11 are rotated to gradually press the first sliding groove 9 and the second sliding groove 10, the sliding plate 8 is pushed to have an upward trend, and therefore the connection between the first support column 2 and the second support column 3 is completed.
