The utility model relates to the technical field of luggage articles, specifically a kind of folding shopping trailer.

Background technique

The elderly likes when doing shopping using trailer containment and transport of objects, in order to save physical strength.But common trailer volume is larger, It is not foldable, it is inconvenient to carry.The shopping bag being convenient for carrying is since without traveling wheel, filling cargo can only carry later, slightly The physical strength of micro- more thing the elderly is with regard to unbearable.

Summary of the invention

The purpose of the utility model is to provide it is a kind of it is structurally reasonable, easy to use, to be suitble to the elderly to use folding Traveling wheel can be folded up when carrying and reduce volume, is convenient for carrying by shopping trailer, and filling cargo later can be by row It walks wheel to decontrol, convenient for walking in tow, mitigates physical load.

Used technical solution is as follows in order to solve the technical problem for the utility model:

Folding shopping trailer described in the utility model includes bottom plate and the traveling wheel that is arranged in below bottom plate, the bottom The upper surface of plate is connected with shopping bag, and handle is provided on shopping bag, and the lower surface of the bottom plate is fixedly installed with the upward U of notch Shape slot is slidably fitted with slide bar in the U-lag, and the both ends of slide bar each extend to the outside of U-lag, and the front end of slide bar is fixed to be connected Be connected to front rod, the rear end of slide bar is fixedly connected with back link, the front rod and back link it is arranged in parallel and hang down Directly in slide bar, the upper end of front rod is fixedly connected with the front end of slide bar, and traveling wheel is installed by wheel shaft in the lower end of front rod；It constitutes The front end of the left side plate of U-lag has forwardly convex convex block.

It is fixedly installed spring base of the sliding sleeve on slide bar on the inner wall of the U-lag, is set with spring on slide bar, The front end of the spring is connected on spring base, rear end is fixedly connected on slide bar.

Card slot of the front end of the convex block with matching front rod.

The upper end of the back link is fixedly connected with the rear end of slide bar, and the lower end of back link is fixedly connected with stabilizer blade.

The shopping trailer is structurally reasonable due to the above structure, production cost is low, easy to use, is suitble to the elderly It uses, traveling wheel can be folded up when carrying and reduce volume, be convenient for carrying, filling cargo later can be by traveling wheel It decontrols, convenient for walking in tow, mitigates physical load.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model one embodiment.

Fig. 2 is the bottom view of Fig. 1 embodiment traveling wheel folded state.

Specific embodiment

As shown in Figure 1, folding shopping trailer described in the utility model includes bottom plate 1 and is arranged in below bottom plate 1 Traveling wheel 2, the upper surface of described bottom plate 1 are connected with shopping bag 3, and handle, shopping bag 3 and handle are provided on shopping bag 3 using soft Soft textile material or non-woven fabrics, plastic film and other material are made, shopping bag 3 be barrel-like structure, fill it is natural after article In vertical.Bottom plate 1 is made of rigid, corrosion-resistant, light-weight plastic plate or aluminium alloy plate.The following table of the bottom plate 1 Face is fixedly installed with the upward U-lag 4 of notch, and slide bar 5 is slidably fitted in the U-lag 4, and slide bar 5 can be in U-lag 4 It slides axially, can also rotate, the both ends of slide bar 5 each extend to the outside of U-lag 4, and the front end of slide bar 5 connects before being fixedly connected with Bar 6, slide bar 5 rear end be fixedly connected with back link 7, the front rod 6 and back link 7 are arranged in parallel and be each perpendicular to Slide bar 5.As a preferred embodiment of the present invention, the slide bar 5, front rod 6 and back link 7 are integrated, using same A piece iron pipe or metallic rod are bent；It is of course also possible to use split type structure, by front rod 6 and back link 7 and slide bar 5 weld together.The upper end of front rod 6 is fixedly connected with the front end of slide bar 5, and the lower end of front rod 6 is installed by wheel shaft walks Wheel 2, the wheel shaft of 6 lower end of front rod is at right angles connect with front rod 6, and traveling wheel 2 is made to be located at side and and the front rod of front rod 6 6 is parallel with 7 place plane of back link；

As shown in Figure 1 and Figure 2, left side plate 82 of the U-lag 4 by being fixedly connected on bottom plate 1, positioned at 5 two sides of slide bar And it is connected between left side plate 82, the trough floor composition positioned at 5 lower section of slide bar, certain left side plate 82 and trough floor Be integrated, section it is u-shaped, with the hangers 83 that extends outward on left side plate 82, in order to pass through hangers 83 On screw left side plate 82 is connected on bottom plate 1, certainly, left side plate 82 can also by welding etc. modes be connected to bottom On plate 1.The front end for constituting the left side plate of U-lag 4 has forwardly convex convex block 8.As shown in Figure 1, current connecting rods 6 are around cunning When the axis of bar 5 rotates to front rod 6 and is in lengthwise position, front rod 6 and slide bar 5 can rearward move one section away from From, stick into front rod 6 between left side plate 82, left side plate 82 clamps front rod 6 from two sides at this time, prevents it to two sides It swings.At this point, the traveling wheel 2 and back link 7 of 6 lower end of front rod play the role of support baseboard 1 jointly, as shown in Fig. 2, two U-lag 4 is arranged in parallel on bottom plate 1, four-point supporting is collectively formed in two groups of traveling wheels 2 and back link 7.Drag 3 upper end of shopping bag Handle when, 3 upper end center of gravity of shopping bag Forward, make the rear end of bottom plate 1 tilts, back link 7 leaves ground, traveling wheel 2 still So contact ground, traveling wheel 2 plays support and slides forward effect when dragging shopping bag 3 moves forward, and drags in this way The walking of shopping bag 3 can substantially mitigate physical load.

As shown in Fig. 2, front rod 6 and slide bar 5 can be moved a distance forwards, make front rod 6 when folding The front of left side plate 82 is slided into, front rod 6 gets rid of the limitation of left side plate 82 at this time, can rotate around the axis of slide bar 5 90 degree, traveling wheel 2 and back link 7 are attached to bottom plate 1, achievees the purpose that reduce volume, facilitate the storage.

As shown in Figure 1, being fixedly installed spring base 9 of the sliding sleeve on slide bar 5, slide bar on the inner wall of the U-lag 4 Spring 10 is set on 5, the front end of the spring 10 is connected on spring base 9, rear end is fixedly connected on slide bar 5.Spring 10 Elastic force slide bar 5 is rearward pushed away, make front rod 6 be unfolded after can stick into automatically in left side plate 82, and can prevent because Road bump causes front rod 6 surprisingly to loosen.Overcome the elastic force of spring 10 by front rod 6 when as long as packing up front rod 6 or Person's slide bar 5 is to being pushed forward.

In addition, card slot 81 of the front end of the convex block 8 with matching front rod 6.Card slot 81 makes semicircular arc, front rod 6 It is sticked into card slot 81 just when packing up, plays the role of locking front rod 6, the unexpected exhibition of the front rod 6 packed up can be prevented It opens, convenient for collecting and carrying.

The upper end of the back link 7 is fixedly connected with the rear end of slide bar 5 as a further improvement of the utility model, after The lower end of connecting rod 7 is fixedly connected with stabilizer blade 11.Stabilizer blade 11 is formed by 90 degree of extension forward fold of back link 7, and stabilizer blade 11 can be with The contact area for expanding back link 7 and ground keeps the support of 1 rear end of bottom plate more firm.
