[0018] Among them, 1 base, 11 longitudinal rod, 111 extension support leg, 12 cross rod, 121 support pad, 13 pad, 2 support frame, 21 front limit surface, 22 rear limit surface, 3 front swing rod, 31 front limit part, 4 rear swing rod, 41 rear limit part, 5 seat mounting plate, 6 front connecting rod, 7 rear connecting rod. DETAILED DESCRIPTION

[0019] The present invention is further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0020] like Figure 1-3The bottom surface of the support pad is flush with the bottom surface of the extension support leg, which increases the supporting force of the base and prevents the swing chair from collapsing when in use, especially when used by multiple people, thereby improving the safety of the swing chair. Pads 13 are welded on the left and right sides of the top of the cross bar, and the cross bar is located at the front and rear sides of the bottom of the pad to ensure that the pad is evenly stressed. A support frame 2 is installed on the top surface of the pad. The support frame is a bent part, and the pad can reduce the height of the bent part so that the bent part has sufficient strength. The support frame is connected to the seat mounting plate 5 through the front swing bar 3 and the rear swing bar 4. The spacing between the two seat mounting plates is 1720mm, which can accommodate four people. The top of the front swing arm is pivotally connected to the top front side of the support frame, the bottom of the front swing arm is pivotally connected to the bottom front side of the seat mounting plate, the top of the rear swing arm is pivotally connected to the top rear side of the support frame, the bottom of the rear swing arm is pivotally connected to the bottom rear side of the seat mounting plate, the middle part of the front swing arm is bent to form a front limit piece 31, the support frame is provided with a front limit surface 21 that matches the front limit piece, the middle part of the rear swing arm is bent to form a rear limit piece 41, the support frame is provided with a rear limit surface 22 that matches the rear limit piece, and the front limit piece matches the front limit surface The rear limiter cooperates with the rear limit surface to limit the forward swing angle of the seat mounting plate to improve the safety of the swing chair when it swings. A front connecting rod 6 is arranged between the front swing rods on both sides, and the two ends of the front connecting rod are fixedly connected to the front limiter. A rear connecting rod 7 is arranged between the rear swing rods on both sides, and the two ends of the rear connecting rod are fixedly connected to the rear limiter. The front connecting rod connects the front swing rods on both sides into a whole, and the rear connecting rod connects the rear swing rods on both sides into a whole, thereby improving the synchronization of the movements of the seat mounting plates on both sides.

[0021] The specific working process and principle of the present invention are as follows: when the outdoor large swing chair iron frame is installed on the base 50, the anti-error groove corresponds to the anti-error boss 501 provided on the base to ensure that the second rolling element faces the reel, and the positioning groove corresponds to the positioning boss 502 on the base to ensure the installation accuracy of the outdoor large swing chair iron frame. Bolts are then used to fix the tube body in the vertical and horizontal directions respectively, thereby improving the firmness of the installation of the outdoor large swing chair iron frame. The present invention provides positioning grooves on the outer peripheral surface of the tube body, which can achieve precise positioning of the outdoor large swing chair iron frame when it is installed, thereby facilitating installation and production. At the same time, a height difference is set between the rollers on both sides as a wear compensation amount for the rollers with more wear, thereby improving the service life of the outdoor large swing chair iron frame and providing basic conditions for reducing the volume of the swing drive device.
