The two movable cross rods 5 are respectively installed between the upper frame 1 and the lower frame 2 and are arranged corresponding to each other. The four ends of the two movable cross rods 5 are respectively pivotally assembled on the fixed seat 3 and the movable seat 4 of the upper frame 1 and the lower frame 2 on the same side; two positioning springs 6, at least one end of which is spherical and elastic, and each positioning spring 6 is respectively arranged in a pipe in the upper frame 1, and the parts of the two positioning springs 6 are elastically protruding from the two through holes 11 of the upper frame 1, and the two movable seats 4 located on the upper frame 1 are provided with a positioning hole 41, and the two When the movable seat 4 moves along the upper frame 1, each positioning spring 6 protrudes from the upper frame 1 to engage and disengage from the positioning hole 41; and two control plates 7, each control plate 7 is spoon-shaped, and is pivotally assembled on one side of each movable seat 4 of the upper frame 1 with a positioning hole 41, one end of each control plate 7 is pivotally assembled on the corresponding peripheral side of the movable seat 4, and the other end of each control plate 7 is movably attached to and away from the peripheral side of the movable seat 4, and each control plate 7 is further protruded with a push control corresponding to the positioning hole 41 of each movable seat 4. The push-control protrusion 71 is provided with two elastic members 72 respectively installed between each control sheet 7 and the corresponding movable seat 4. Each elastic member 72 pushes one end of each control sheet 7 with the push-control protrusion 71 away from the movable seat 4. When one end of each control sheet 7 with the push-control protrusion 71 approaches the movable seat, each push-control protrusion 71 pushes each positioning spring member 6 to be elastically compressed inward and release the engagement with each positioning hole 41. The release of each positioning spring member 6 from each positioning hole 41 allows each movable seat 4 to be movable and displaced along the upper frame 1.
[0037] According to the main technology described above for the utility model, the utility model can be applied to a general basket, a storage basket or a cart (such as Figures 14 to 16As shown in the figure, when the user does not need to store, load or use, he only needs to operate each control piece 7, move one end of each control piece 7 with a push-control protrusion 71 toward each movable seat 4 located on the upper frame 1, and push the corresponding positioning springs 6 with each push-control protrusion 71, so that each positioning spring 6 is elastically compressed toward the inside of the upper frame 1 and disengaged from the clamping connection with the positioning hole 41 on each movable seat 4, so that each movable seat 4 of the upper frame 1 and the lower frame 2 can move toward the fixed seat 3, and at the same time, each movable cross rod 5 will also be folded along with the pivot swing, so that the upper frame 1 gradually approaches the lower frame 2. This state is the folding mode.
[0038] When the user needs to load or remove the items, the upper frame 1 is simply lifted upward in the direction away from the lower frame 2. At this time, the movable cross bars 5 will be pivoted and unfolded, and at the same time, the movable seats 4 located on the upper frame 1 and the lower frame 2 will gradually move away from the fixed seats 3. The movement of the movable seats 4 located on the upper frame 1 is to move toward the position of the positioning springs 6. When the positioning springs 6 encounter the movable seats 4, they will be pushed and compressed by the inside of the movable seats 4. After the continuous movement of the movable seats 4, after the positioning springs 6 correspond to the positioning holes 41 of the movable seats 4, the positioning springs 6 will be released and pop out of the positioning holes 41. In this way, the movable seats 4 will be positioned and cannot move anymore. At this time, the distance between the upper frame 1 and the lower frame 2 is the farthest, forming a use mode that can be loaded and removed. The positioning of the movable seats 4 can be quickly released under the simple control of the control sheets 7, and the movable seats 4 can be moved and connected with the positioning springs 6 by simply lifting the upper frame 1. This is a simple and convenient operation for the user. Please refer to Figures 7 to 11 shown.
[0039] Based on the above description, other features are further described below. First, please refer to Figures 2 to 4 , Fig.10 , Fig.11As shown, during the transition from the folded mode in which the upper frame 1 is close to the lower frame 2 to the use mode in which the upper frame 1 is away from the lower frame 2, in order to allow each positioning spring 6 to be pressed and retracted by the movable seat 4, two avoidance blocks 42 are further protruded outward at both ends of each movable seat 4 of the upper frame 1, and each movable seat 4 is respectively formed with a channel 43 sleeved on the upper frame 1, and the channel 43 of each movable seat 4 extends to form a avoidance groove 44 corresponding to each avoidance block 42, and each avoidance groove 44 is connected to the channel 43, so the orifice diameter of the channel 43 is relatively large, and when each movable seat 4 moves toward each positioning spring 6, each positioning spring 6 enters through the corresponding avoidance groove 44 because it is not compressed, until each positioning spring 6 is After the protruding part of the elastic member 6 hits the inner wall of the channel 43, each positioning elastic member 6 is pushed by the wall of the channel 43 of each movable seat 4 to compress and store force, and each positioning elastic member 6 is elastically reset and stuck in each positioning hole 41 until it corresponds to each positioning hole 41. Therefore, the design of each avoidance groove 44 is mainly to prevent each positioning elastic member 6 from being stuck at the hole mouth of the channel 43 and making it impossible for the movable seat 4 to continue to move. Therefore, the design of each avoidance groove 44 is used to first allow each positioning elastic member 6 to smoothly enter the movable seat 4, and then use the connection between the avoidance groove 44 and the inner wall of the channel 43 to guide and push the protruding part of each positioning elastic member 6 to be compressed inward, so that each positioning elastic member 6 can be elastically stuck in each positioning hole 41 smoothly, and each movable seat 4 can be fixed in position.
[0040] See also Figure 3 , Figure 4 , Fig.12 , Fig.13 As shown, in order to make the upper frame 1 and the lower frame 2 stable and not to rise and fall arbitrarily in the folded mode, the utility model further extends a rib 45 downward on one side of each movable seat 4 corresponding to each control sheet 7, and each control sheet 7 is pivotally connected to each rib 45, and each control sheet 7 is pivotally connected to each movable seat 4. One end of the further downward extension forms a control handle 73, and each control handle 73 is based on the pivotal connection between each control sheet 7 and the movable seat 4 as the central force point to control each push control protrusion 71 to push each positioning spring 6 out of the positioning hole 41, and each movable seat 4 located on the lower frame 2 is further provided with a card block 46 on the inner side, and each control handle 73 is provided with a locking hole 7 at the end thereof. 31, so when the movable seats 4 located on the upper frame 1 are in a movable state, the upper frame 1 approaches the lower frame 2, and the locking holes 731 of the control handles 73 are aligned with the clamping blocks 46, and the clamping blocks 46 are inserted into the locking holes 731 to limit the pivoting of the two movable cross rods 5 and the distance between the upper frame 1 and the lower frame 2. When the user wants to store the utility model, as long as the locking holes 731 of the control handles 73 are connected to the clamping blocks of the movable seats of the lower frame 2, no matter how the user places the utility model, the upper frame 1 will not automatically move away from the lower frame, and the movable cross rods 5 will not automatically pivot and unfold.
[0041] The main feature of the present invention is that both sides of the movable seats 4 of the upper frame 1 are provided with controllable mechanisms, which are mainly used to allow users to operate more accurately, so please refer to Figures 1 to 11 As shown, two external control plates 8 are further provided, which are pivotally assembled on the outer side of each movable seat 4 located on the upper frame 1. The structure of each external control plate 8 is similar to that of each control plate 7, and each movable seat 4 extends a mounting rib 47 downwardly corresponding to the pivot group of each external control plate 8. One end of each external control plate 8 is pivotally connected to each mounting rib 47, and the other end of each external control plate 8 is movable close to and away from the movable seat 4. The through holes 11 of the upper frame 1 are set to penetrate laterally, and the part of each positioning spring 6 is movably protruded from the two end openings of each through hole 11, and each movable seat 4 located on the upper frame 1 corresponds to the protrusions at both ends of each positioning spring 6. The number of positioning holes 41 of each movable seat 4 of the upper frame 1 It corresponds to the protruding part of each positioning spring 6; and each external control piece 8 is further provided with a push block 81 on one side corresponding to the protruding part of each positioning spring 6. The function of each push block 81 is the same as that of each push control protrusion 71. Each push block 81 pushes the positioning spring 6 inward to compress and accumulate force and disengage from the engagement with the positioning hole 41 when each external control piece 8 approaches the movable seat 4. Therefore, according to the above description, when the user operates, he must press the parts of each control piece 7 with the push control protrusion 71 and the parts of each external control piece 8 with the push block 81 with two fingers of both hands, so that the parts of each positioning spring 6 protruding from the movable seat 4 are pushed inward, thereby releasing the fixation of each movable seat 4.
[0042] Finally, in order to prevent the user from slipping when pressing the parts of each control sheet 7 provided with the push-control protrusion 71 and each outer control sheet 8 provided with the push-detent block 81, the utility model further convexly provides a plurality of anti-slip convex ribs 9 on the outer peripheral surface of one end of each control sheet 7 provided with the push-control protrusion 71, and also convexly provides a plurality of anti-slip convex ribs 9 on the opposite side of each outer control sheet 8 provided with the push-detent block 81. The main purpose is to use the arrangement of each anti-slip convex rib 9 to provide friction when the user contacts and presses, thereby achieving a reliable pressing operation. Please refer to Fig.17 shown.
