DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0024] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0025] Embodiment one: a convenient storage handcart, including first placement plate 1 and second placement plate 2, the inner side wall of second placement plate 2 is fixedly connected with a plurality of inner rods 3, and the other end of each inner rod 3 is fixedly connected with fixed column 4 at both ends, and the other end of each fixed column 4 is fixedly connected with first spring 5, and the other end of first spring 5 is fixedly connected with plug rod 6, and first placement plate 1 is fixedly connected with a plurality of rod sleeves 7 inside, and inner rod 3 is slidingly connected inside rod sleeve 7, and a plurality of insertion holes 8 are formed in the inside of rod sleeve 7, and insertion hole 8 corresponds to plug rod 6, and plug rod 6 is slidingly connected in insertion hole 8, and second placement plate 2 is fixedly connected with a plurality of support rods 9 on the outer side wall, and a plurality of sliding grooves 10 are formed in the inside of first placement plate 1, and sliding groove 10 corresponds to support rod 9, and support rod 9 is slidingly connected in sliding groove 10, and placement slot 17 is formed in the top of first placement plate 1 and second placement plate 2, and pull rod 11 is rotatably connected at one end of first placement plate 1, and pull rod 11 corresponds to placement slot 17, and pull rod 11 is inserted in placement slot 17, and handle 12 is fixedly connected on the outer side wall of second placement plate 2.

[0026] The operator holds the handle 12 with his hand and then applies an outward pulling force, under the action of the pulling force, the second placing plate 2 starts to move outward, since the second placing plate 2 is connected with the inner rod 3, so the inner rod 3 will move outward in the rod sleeve 7 synchronously with the movement of the second placing plate 2. At this time, the plug rod 6 located at the other end of the inner rod 3 and connected with the first spring 5 will also move outward, in this outward movement process, the plug rod 6 will be extruded by the rod sleeve 7, thereby compressing the first spring 5, and making the plug rod 6 gradually shrink into the inner rod 3, according to the actual size of the goods to be placed, the second placing plate 2 is pulled to the appropriate position, the plug rod 6 corresponds to the insertion hole 8 in the rod sleeve 7, under the elastic restoring force of the first spring 5, the plug rod 6 will pop out and smoothly slide into the insertion hole 8, thereby realizing the fixation of the relative position of the second placing plate 2 and the first placing plate 1. Through the coordinated cooperation of a series of components, the second placing plate 2 can be quickly pulled out from the inside of the first placing plate 1 and separated to the outside, effectively increasing the placing area of the whole device, solving the problem of difficult to accommodate large goods due to limited placing area, improving the practicability and flexibility of the device, facilitating the storage and transportation of goods of different sizes, and the support rod 9 gradually pulls out from the sliding groove 10 for auxiliary support.

[0027] Embodiment two: the difference between this embodiment and embodiment one is that the second placing plate 2 is fixedly connected with a fixed block 13 on the outer side wall, the fixed block 13 is rotatably connected with a rotating rod 14 inside, the rotating rod 14 is rotatably connected with a screw rod 15 at the other end, the second placing plate 2 is provided with a threaded hole 16 on the top, and the screw rod 15 is rotatably connected in the threaded hole 16, a pair of support legs 18 are fixedly connected on the outer side wall of the first placing plate 1, two pairs of second springs 22 are fixedly connected on the top of the first placing plate 1, a buffer pad 19 is fixedly connected on the top of the second spring 22, a plurality of limiting grooves 21 are formed in the first placing plate 1, and the buffer pad 19 is fixedly connected with a limiting block 20 on both side walls, and the limiting block 20 is slidably connected in the limiting groove 21.

[0028] When the staff enables the device, the first step is to rotate the rotating screw 15 until it is rotated out of the threaded hole 16, and the two are disconnected. Then, pull the rotating rod 14 outward, and the rotating rod 14 can only rotate within a specific track and range due to the limitation of the fixed block 13, and continue to rotate until it is rotated to the outer area of the second placement plate 2, the pull rod 11 is pulled out of the placement slot 17, and it is rotated to one end of the first placement plate 1. When the pull rod 11 is rotated to the rear end position of the first placement plate 1, it will collide with the buffer pad 19. At this moment, the buffer pad 19 starts to move downward under the impact force, and its movement is guided and limited by the limiting block 20 in the limiting slot 21. In the process of moving downward, the elastic material inside the buffer pad 19 will be extruded, and the impact energy brought by the pull rod 11 will be absorbed and resolved by the elastic deformation, thereby effectively preventing the pull rod 11 from being damaged due to direct and violent impact on the first placement plate 1. The staff pushes the entire device together with the goods to realize the convenient transfer of the goods by holding the pull rod 11 with his hand and combining the universal wheel at the bottom of the device. This design effectively solves the problems of component collision and damage during operation conversion and inconvenient movement, improves the safety and convenience of the device, and guarantees the efficiency and stability of the goods handling.

[0029] The working principle is that when the staff uses the device, first rotate the rotating screw 15 so that the screw 15 is separated from the threaded hole 16, then rotate the rotating rod 14 outward, and the rotating rod 14 is limited in the fixed block 13, and when the rotating rod 14 is rotated to the outside of the second placement plate 2, the pull rod 11 is taken out of the placement slot 17 and rotated to one end of the first placement plate 1. When the pull rod 11 is rotated to the rear end of the first placement plate 1, it will hit the buffer pad 19, and the buffer pad 19 will move downward and be limited in the limiting slot 21 by the limiting block 20. When the buffer pad 19 moves downward, it will extrude the buffer pad 19, and the elasticity of the buffer pad 19 will buffer the pull rod 11 to avoid direct impact of the pull rod 11 on the first placement plate 1. After taking out, hold the pull handle 12 and pull it outward to drive the second placement plate 2 to move outward, and when the second placement plate 2 moves, the inner rod 3 will move outward in the rod sleeve 7, and at this time the plug rod 6 on the other end of the inner rod 3 will move outward together, and will compress the first spring 5 and the plug rod 6 into the inner rod 3 when moving. According to the size of the goods, pull it to the appropriate position, and the plug rod 6 and the plug hole 8 in the rod sleeve 7 correspond exactly. At this time, the elasticity of the first spring 5 will drive the plug rod 6 to move outward and slide into the plug hole 8 for fixation. Through their cooperation, the second placement plate 2 can be quickly separated to the outside of the first placement plate 1, thereby increasing the placement area, and the support rod 9 is gradually pulled out of the sliding slot 10 for auxiliary support.

[0030] It is to be understood that the terminology "first" and "second" and the like used herein is merely intended to differentiate one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between such entities or operations.
