Problems solved by technology

[0002] With the increase of the number of vehicles and the increase of the application scenarios of the existing car storage box, the demand for the car storage box is greatly increased, but it is generally only used for storing and organizing items, without other functions, and it is used outdoors When there are a lot of items to be moved, moving the whole box out or moving it into the trunk of the car is relatively heavy, which is even more of a challenge for the weak, and even requires the cooperation of two people to complete
[0003] When going to the supermarket to shop, especially during the holidays, the shopping volume is relatively large. After transporting the items to the trunk of the car through the shopping cart provided by the supermarket, you need to put them in the trunk of the car one by one, and when you get home, Regardless of whether there is a parking space in the community (most of the cars are parked on the side of the road outside the community), you need to take out the items in the trunk again, and bring the big bags and small bags home, which is quite a hard physical work. And the test of endurance, especially for those with children, it is very uncomfortable to take care of children and carry items, and sometimes it will cause noise between young couples

Embodiment 1

[0041] Such as figure 1 As shown, in order to achieve the purpose of directly pushing items to the car trunk or easily pulling them out from the car trunk, this embodiment provides a foldable trolley, including a support platform 1 and a support installed at the bottom of the support platform 1 Leg 2, the top section of the supporting leg 2 is movably connected with the mounting block 3 installed at the bottom of the supporting platform 1 .

[0042] pass figure 2 It can be seen that a fixed pin 4 and a limiting hole 5 are sequentially arranged on the inner surface of the top section of the supporting leg 2 from top to bottom, and image 3 The shown mounting block 3 is provided with a fixing hole 7 for inserting the fixing pin 4, so that the supporting leg 2 can rotate around the fixing pin 4 as a rotating shaft or rotate around the fixing hole 7 with the fixing pin 4, for example, it can Bearings are installed in the fixing holes 7, and then connected with the fixing pins 4...

Embodiment 2

[0045] In order to facilitate a better understanding that the aforementioned foldable trolley can be folded by retracting the supporting legs 2, this embodiment provides Figure 4 The shown self-resetting limit ejector mechanism includes a limit ejector pin 9, a return spring 10 with one end clamp at the tail end of the limit ejector pin 9, and a return spring 10 whose two ends are fixed on the inner side of the installation block 3 through connecting round pipes 11. The spring supporting member 12 and the drawing member 13 fixedly connected with the tail end of the limit push pin 9 pass through the perforation on the return spring supporting member 12 .

[0046] A limit tube 14 is arranged on the side of the tail end of the return spring support member 12 facing the limit push pin 9 to be sleeved on the return spring 10 to ensure that the return spring 10 is compressed after the limit push pin 9 is pulled out. In the process or in the process of the reset spring 10 pressing t...

Embodiment 3

[0054] and Image 6 A self-resetting limit pin ejector mechanism of another structure is provided, including a housing 19, a ejector pin 20 that can pass through the lower positioning hole 8, a compression spring 21 and a booster assembly, a ejector 22 and a ejector rod 23; wherein, the ejector pin 20 and the compression spring 21 are installed in the blind hole 24 on one side of the housing 19, and the compression spring 21 is placed between the bottom of the blind hole 24 and the ejector pin tail end 25 of the ejector pin 20, The front end of the ejector pin 20 extends outside the blind hole 24; Figure 7 It can be seen that an inclined boosting surface 26 is arranged on the boosting side 30 parallel to the jacking pin 20 of the jacking pin tail end 25, and the tilting boosting surface 26 is from the front end of the jacking pin tail end 25 to the bottom of the jacking pin tail end 25. The direction of the rear end is inclined, and the inclined pushing surface 26 is arrange...

Abstract

The foldable trolley provided by the present invention comprises a support platform and a support leg installed at the bottom of the support platform, the top section of the support leg is movably connected with the support platform; pin and limit hole; the support platform is provided with a fixed hole for the fixed pin to insert, and the support leg can rotate around the fixed pin as a rotating shaft or rotate around the fixed hole with the fixed pin; the support platform is provided with a Lower positioning hole; when the supporting leg is at a position perpendicular to the supporting platform, the lower positioning hole is directly opposite to the limiting hole; a self-resetting limit pin mechanism is installed on the inner side of the supporting platform to pass through the lower positioning hole Then insert it into the limiting hole to prevent the supporting legs from swinging. Through the foldable trolley, it is possible to push the articles into the trunk of the car together with the car or pull them out from the trunk of the car without unloading, which is simple and easy.
