Connecting rod type folding support

Abstract

The utility model discloses a connecting rod type folding support which comprises a middle rod, two sides of the middle rod are respectively hinged with a four-connecting-rod folding frame, after being unfolded, each four-connecting-rod folding frame comprises an upper-layer frame hinged to the upper end of the middle rod, a lower-layer frame hinged to the lower end of the middle rod and supporting legs hinged to the upper-layer frame and the lower-layer frame, and a sliding sleeve is installed on the middle rod in a sliding mode. A supporting rod is hinged between the sliding sleeve and the upper-layer frame, and a locking device is installed between the sliding sleeve and the middle rod. Due to the fact that the four-connecting-rod folding frame is adopted, the four-connecting-rod folding frame is stable in structure, a round rod can be adopted as a main frame rod piece, the thickness of a folded frame body can be reduced, the occupied space is small, and therefore the packaging, storing and transporting cost is reduced.

Description

Technical Field

[0001] This utility model relates to the technical field of folding brackets for laying out items, specifically to folding brackets that employ a linkage-type folding mechanism. Background Technology

[0002] Currently, most folding racks used for displaying items, such as clothes drying racks, are cross-shaped folding racks. The main frame members of these cross-shaped folding racks are generally made of square tubing, and the folded rack is still too thick, taking up a lot of space and resulting in high packaging, storage, and transportation costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a linkage-type folding bracket with a small folding space.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a linkage-type folding bracket, characterized in that: it includes a central rod, and a four-link folding frame is hinged to each side of the central rod. After the four-link folding frame is unfolded, it includes an upper frame hinged to the upper end of the central rod, a lower frame hinged to the lower end of the central rod, and support legs hinged to the upper and lower frames. A sliding sleeve is installed on the central rod, and a support rod is hinged between the sliding sleeve and the upper frame. A locking device is installed between the sliding sleeve and the central rod.

[0005] Based on the above, the locking device includes a hook with a hinged sliding sleeve and a pin fixed to the center rod.

[0006] The beneficial effects of this utility model are as follows: Since the folding bracket of this utility model adopts a four-link folding frame, the four-link folding frame has a stable structure and can use round rods as the main frame members, which can reduce the thickness of the frame after folding and occupy less space, thereby reducing packaging and storage costs. Attached Figure Description

[0009] like Figure 1 , 2As shown, a linkage-type folding bracket includes a central rod 1, with a four-bar linkage folding frame hinged to each side of the central rod 1. When unfolded, the four-bar linkage folding frame includes an upper frame 2 hinged to the upper end of the central rod 1, a lower frame 3 hinged to the lower end of the central rod 1, and support legs 4 hinged to the upper frame 2 and the lower frame 3. A sliding sleeve 5 is installed on the central rod 1, and a support rod 6 is hinged between the sliding sleeve 5 and the upper frame 2. A locking device is installed between the sliding sleeve 5 and the central rod 1. The locking device is a conventional locking device that prevents the sliding sleeve 5 from sliding.

[0010] When unfolded, the sliding sleeve 5 slides upward until the upper shelves 2 on both sides are in a flat, unfolded state. Then, the locking device locks the sliding sleeve 6, and the support rod 6 fixes the bracket in a fully unfolded state. After the linkage-type folding bracket is fully unfolded, the upper shelf 2 and the lower shelf 3 can be used to lay out items. When laying out clothes for drying, in order to facilitate the drying of clothes on the lower shelf 3, the lower shelf 3 can be set to tilt slightly downward from the inside out. When folding, the locking device is released, and the four-link folding bracket on both sides folds downward. At this time, the sliding sleeve 5 will slide downward along the middle rod 1 until the bracket is fully folded.

[0011] In this embodiment, the locking device includes a hook 7 of a hinged sliding sleeve 5 and a pin 8 fixed to the central rod 1. Since the central rod 1 is hinged to the upper frame 2 through a T-shaped hinge seat 9, the pin 8 is fixed to the T-shaped hinge seat. After the hook 7 hooks the pin 8, the bracket can be fixed in a fully extended state.

Claims

1. A linkage-type folding bracket, characterized in that: It includes a central pole, with a four-bar folding frame hinged to each side of the central pole. When unfolded, the four-bar folding frame includes an upper frame hinged to the upper end of the central pole, a lower frame hinged to the lower end of the central pole, and support legs hinged to the upper and lower frames. A sliding sleeve is installed on the central pole, and a support rod is hinged between the sliding sleeve and the upper frame. A locking device is installed between the sliding sleeve and the central pole.

2. The linkage-type folding bracket according to claim 1, characterized in that: The locking device includes a hook with a hinged sliding sleeve and a pin fixed to the center rod.
