Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, specifically to a foldable dual-purpose handcart. Background Technology

[0002] In the medical environment, trolleys are an important tool for transporting and delivering medical supplies. For example, pharmacy staff use trolleys to deliver prepared medicines to various wards or treatment areas. For medical equipment that needs to be moved, such as electrocardiographs and ultrasound equipment, trolleys are also used to facilitate the handling, collection and transportation of medical waste, ensuring environmental cleanliness and avoiding cross-infection.

[0003] The existing handcarts are generally flatbed carts. Although such carts can meet daily loading needs, if too many materials are loaded or the materials are not easy to stabilize, the loading capacity and stability of the cart will be insufficient. This will require personnel to manually assist and support the materials on the cart during transportation, increasing the limitations during operation. At the same time, when not in operation, the carts can only be arranged and placed. However, since there are a certain number of carts, this placement method will cause the carts to occupy too much space, which is not conducive to the storage and placement of the carts.

[0004] Therefore, this application proposes a foldable dual-purpose handcart. Utility Model Content

[0024] Example 1

[0025] To address the technical problems in the background section, the following foldable dual-use handcart is provided:

[0026] Combination Figures 1-5 As shown, the present invention provides a foldable dual-purpose handcart, including a carrier plate 1. Two sets of flipping components 4 are fixedly installed on one side of the top of the carrier plate 1. A push-pull handle 2 is connected to the top of the flipping components 4. Four wheels 3 are fixedly installed at the four corners of the bottom of the carrier plate 1. Three sets of enclosure components 5 are connected to the bottom of the carrier plate 1. Limiting paddles 6 are fixedly installed on three sides of the carrier plate 1, and the limiting paddles 6 limit the enclosure components 5.

[0027] During this process, the trolley is loaded onto the carrier plate 1. Personnel place the materials to be transported on the carrier plate 1. The flipping component 4 and the push-pull handle 2 are installed and cooperated to achieve the folding effect of the push-pull handle 2. The operation can be switched according to the actual operation situation. During non-operation periods, the trolley can be stacked to save operating space. The enclosure component 5 on the carrier plate 1 allows the trolley to switch its own operating state according to the actual operation needs. The trolley can meet the daily transportation operation and increase its own limiting effect and loading capacity when there are too many materials, realizing the multi-purpose operation of the trolley.

[0028] The flipping component 4 includes a docking component 41 and a plugging component 42. The docking component 41 is fixedly installed on one side of the top of the carrier plate 1, and the plugging component 42 is fitted on one side of the docking component 41 for positioning and matching. The enclosure component 5 includes a transmission component 51 and an enclosure component 52. Three sets of transmission components 51 are fitted on the bottom of the carrier plate 1, and the movable end of the transmission component 51 is docked with the enclosure component 52. The limiting piece 6 limits and matches the enclosure component 52.

[0029] During use, the plug-in component 42 cooperates with the docking component 41 to limit and fix the docking component 41. After the work is completed, the personnel can release the restriction on the docking component 41 through the plug-in component 42, and drive the push-pull handle 2 to fold down through the docking component 41 to store the cart. If there are many materials being transported, the cart can be switched to the working state. This is accomplished by driving and adjusting the enclosure component 52 through the transmission component 51, thereby expanding the working range of the cart.

[0030] Example 2

[0031] like Figure 1 and Figure 5 As shown, based on the above embodiments, this embodiment further provides the following:

[0032] In this embodiment, the docking component 41 includes a docking seat 411, a second rotating shaft 412, a docking hole 413, and a mounting seat 414. The docking seat 411 is fixedly installed on one side of the top of the carrier plate 1. The mounting seat 414 is movably installed inside the docking seat 411 through the second rotating shaft 412. The mounting seat 414 and the docking seat 411 are provided with corresponding docking holes 413.

[0033] The insertion component 42 cooperates with the docking component 41 to limit and fix the docking component 41;

[0034] During this period, the mounting base 414 rotates within the docking base 411 via the second pivot 412, thus enabling the push-pull handle 2 to rotate itself. This allows the trolley to be positioned and erected during use, and to be rotated and lowered when not in use.

[0035] In this embodiment, the plug-in component 42 includes a first mounting block 421, a slide rail 422, a second mounting block 423, a spring 424, a lever 425, and a plug pin 426. The first mounting block 421 is fixedly mounted on the carrier plate 1 inside the docking seat 411. The second mounting block 423 is slidably mounted on the carrier plate 1 on one side of the first mounting block 421. The second mounting block 423 is slidably connected to the carrier plate 1 through the slide rail 422. The spring 424 is fixedly mounted between the first mounting block 421 and the second mounting block 423. The lever 425 is fixedly mounted on the top of the second mounting block 423. The plug pin 426 is fixedly mounted on the inner side of the second mounting block 423. The plug pin 426 passes through the docking hole 413 and positions the mounting seat 414 inside the docking seat 411.

[0036] By combining the above, when the trolley is not in use, the lever 425 can be manually moved. The bottom of the lever 425 slides on the slide rail 422 and compresses the spring 424. At that time, the insertion pin 426 inside the lever 425 will be pulled out from the docking hole 413 in the mounting base 414 and the docking base 411. After the mounting base 414 in the docking base 411 is unrestrained, the person can push and pull the handle 2 to flip down through the cooperation of the mounting base 414 and the second rotating shaft 412.

[0037] When using it, you can operate it in the manner described above.

[0038] Example 3

[0039] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0040] In this embodiment, the conductive component 51 includes a mounting sleeve 511, a guide plate 512, a first rotating shaft 513, a push plate 514, a snap-fit ​​groove 515, and a guide block 516. Three sets of mounting sleeves 511 are fixedly installed on the bottom of the carrier plate 1. Three sets of guide grooves 12 are provided on the bottom of the carrier plate 1. The guide plate 512 is slidably installed inside the guide groove 12 through the guide block 516. The push plate 514, which penetrates the mounting sleeve 511, is fixedly installed on the inner side of the guide plate 512. The first rotating shaft 513, which is movably connected to the support sleeve 521, is mated and installed on the push plate 514. The snap-fit ​​groove 515 is provided on the outer side of the mounting sleeve 511.

[0041] When in use, if there are a lot of materials being transported, the trolley can be switched to the working state; this is accomplished by driving and adjusting the enclosure component 52 through the transmission component 51.

[0042] During this process, when personnel pull the enclosure component 52, the enclosure component 52 will pull the push plate 514 through the first rotating shaft 513, causing the push plate 514 to be guided outward within the mounting sleeve 511. During the guiding process, with the cooperation of the snap-fit ​​groove 515 and the guide block 516, the push plate 514 is linearly pushed, causing the enclosure component 52 to be pulled out until the guide plate 512 on the push plate 514 is pushed to the front end. Then, with the cooperation of the first rotating shaft 513, the enclosure component 52 is flipped, causing the enclosure component 52 to be flipped and erected, entering the working state.

[0043] In this embodiment, the enclosure component 52 includes a support sleeve 521, a positioning knob 522, a mesh panel 523, an inner frame 524, a snap-fit ​​block 525, and an operation port 526. The push plate 514 is movably mounted with the support sleeve 521 via a first rotating shaft 513. The inner frame 524 is installed inside the support sleeve 521, and the mesh panel 523 is fixedly installed inside the inner frame 524. The snap-fit ​​block 525 is fixedly installed on the outer side of the support sleeve 521, and the snap-fit ​​block 525 engages with the snap-fit ​​groove 515. Both sides of the support sleeve 521 are provided with operation ports 526, and the positioning knob 522 is installed inside the operation port 526. The positioning knob 522 positions the inner frame 524.

[0044] By combining the above, once the enclosure component 52 enters the upright state, it can cooperate with the other two sets to enter the enclosure state, so as to realize the loading capacity of the trolley and the limiting effect on the loaded materials.

[0045] If the current enclosure status is insufficient, personnel can pull out the built-in frame 524 inside the support sleeve 21 until a suitable height is reached. Then, personnel can rotate the positioning knob 522 inside the operation port 526 to position the built-in frame 524. In this way, with the cooperation of the built-in frame 524 and the mesh plate 523, the height of the support sleeve 21 is extended, increasing the enclosure range of the trolley.

[0046] In this embodiment, mounting ports 11 are provided on both sides and the front side of the carrier plate 1, and the mounting ports 11 are mated and cooperate with the support sleeve plate 521.

[0047] During this period, when the support sleeve 21 is in the upright position, it is necessary to ensure that the support sleeve 21 is placed in the assembly port 11 so that the limit piece 6 can complete the limit of the support sleeve 21.
