Description

Technical Field

[0001] This technical solution relates to the field of shopping cart technology, specifically a folding shopping cart. Background Technology

[0002] Shopping carts are a common tool for people when shopping, especially when carrying heavy items, which can bring great convenience. For example, using a shopping cart when buying groceries can avoid carrying multiple bags by hand, and it is more friendly to the elderly.

[0003] For example, Chinese patent CN201921433480.5 discloses a shopping cart vegetable box, which includes a shopping cart body, a vegetable box and a basket. The shopping cart body is provided with a first column and a second column. However, because the first column cannot be bent and folded, the shopping cart body is large in size, occupies a lot of space, and is inconvenient to carry and store. Utility Model Content

[0004] The purpose of this technical solution is to provide a folding shopping cart. By rotating a pull rod frame one on the base and connecting a rotatable pull rod frame two to the pull rod frame one, the pull rod device can be folded and stored, thus improving the problem of inconvenient storage and carrying of existing shopping carts due to the inability to fold the pull rod.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A folding shopping cart, comprising:

[0007] Base;

[0008] A wheel assembly, which is mounted on the lower end of the base;

[0009] A pull rod device, the lower end of which is rotatably connected to the base;

[0010] The pull rod device includes:

[0011] A tie rod bracket, the lower end of which is rotatably connected to the base;

[0012] Tie rod bracket two, the lower end of which is rotatably connected to the upper end of tie rod bracket one;

[0013] A rotation limiting mechanism is movably installed between the first tie rod frame and the second tie rod frame to limit the rotation of the second tie rod frame on the first tie rod frame.

[0014] The folding of the pull rod device is achieved by rotating the second pull rod on the first pull rod, and the first pull rod rotating on the base.

[0015] Preferably, the upper end of the base is provided with a clearance groove, and the front and rear ends of the clearance groove respectively pass through the front and rear ends of the base; the lower end of the first tie rod is placed in the clearance groove and hinged to the side wall of the clearance groove.

[0016] Preferably, the rear end of the clearance groove is provided with a limited turning section;

[0017] The rotation limiting part is located above the rear end of the hinge joint between the first tie rod and the clearance groove, such that the front end of the rotation limiting part abuts against the rear end of the first tie rod.

[0018] Alternatively, the rotation limiting part is located below the front end of the hinge joint between the first tie rod and the clearance groove, such that the rear end of the rotation limiting part abuts against the front end of the first tie rod.

[0019] Preferably, when the first pull rod bracket and the second pull rod bracket are rotated and placed in the clearance groove, the second pull rod bracket does not protrude from the upper end surface of the base.

[0020] Preferably, the upper end of the first tie rod bracket has a first connecting part, and the lower end of the second tie rod bracket has a second connecting part, and the first connecting part and the second connecting part are rotatably connected.

[0021] The rotation limiting mechanism includes a rotation limiting sleeve, which is slidably sleeved on the first connecting part and the second connecting part to limit the rotation between the first connecting part and the second connecting part.

[0022] Preferably, a limiting part is provided on the first connecting part, and the limiting part movably abuts against the lower end of the limiting sleeve to restrict the movement of the limiting sleeve on the first connecting part.

[0023] Preferably, a connecting plate is rotatably provided between the first connecting part and the second connecting part, the first connecting part is provided with a first limiting part and a first arc-shaped part at one end, and the second connecting part is provided with a second limiting part and a second arc-shaped part at one end;

[0024] The first limiting part and the second limiting part are movably abutted together to limit the rotation of the first connecting part and the second connecting part; the first arc-shaped part and the second arc-shaped part enable the first connecting part and the second connecting part to rotate on the connecting plate.

[0025] Preferably, the front side wall of the clearance groove has an anti-detachment protrusion. When the first pull rod is rotated and placed in the clearance groove, the anti-detachment protrusion abuts against the first pull rod, thereby restricting the rotation of the first pull rod in the clearance groove.

[0026] Preferably, the rear end sidewall of the clearance groove has an anti-detachment protrusion 2. When the tie rod frame 2 is rotated and placed in the clearance groove, the anti-detachment protrusion 2 abuts against the tie rod frame 2, thereby restricting the rotation of the tie rod frame 2 in the clearance groove.

[0027] Preferably, it further includes: a shopping bag, which is detachably mounted on the pull rod device, and the bottom of the shopping bag is movably abutting against the base;

[0028] The shopping bag is provided with a connecting strap at the rear end, and the pull rod device is passed between the connecting strap and the shopping bag;

[0029] The pull rod device has an anti-detachment rod, and the shopping bag is provided with an anti-detachment part. The front end of the anti-detachment part is detachably connected to the shopping bag, and a fixing space is formed between the anti-detachment part and the shopping bag for fixing the anti-detachment rod.

[0030] The base end face is provided with a number of anti-slip grooves; when the pull rod device is in the folded state, the anti-detachment rod is placed in the anti-slip groove.

[0031] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0032] 1. This technical solution rotatably mounts a pull rod frame one on the base, and rotatably mounts a pull rod frame two on the pull rod frame one, thereby realizing the folding and storage of the pull rod device, reducing storage space, and facilitating storage and carrying; at the same time, by adjusting the rotation limiting mechanism, the pull rod frame one and the pull rod frame two are kept in the unfolded state, which is simple in structure and easy to operate.

[0033] 2. This technical solution has a clearance groove on the base. When the first and second pull rods are rotated to the folded state, the first and second pull rods can be placed in the clearance groove, which prevents the first and second pull rods from protruding from the top of the base and occupying extra space, making it convenient for storage and placement.

[0047] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-9 .

[0048] Example 1:

[0049] Combination Figures 1-3 A folding shopping cart, comprising:

[0050] Base 1;

[0051] The wheel assembly 2 is rotatably mounted at the lower end of the base 1;

[0052] The lower end of the pull rod device 3 is rotatably connected to the base 1 for the user to pull.

[0053] The tie rod device 3 includes:

[0054] Tie rod bracket 31, the lower end of which is rotatably connected to base 1;

[0055] Tie rod bracket 2 32, the lower end of which is rotatably connected to the upper end of tie rod bracket 1 31;

[0056] The rotation limiting mechanism 33 is movably installed between the first tie rod frame 31 and the second tie rod frame 32 to limit the rotation of the second tie rod frame 32 on the first tie rod frame 31;

[0057] By rotating the second pull rod bracket 32 ​​on the first pull rod bracket 31, and the first pull rod bracket 31 rotating on the base 1, the first pull rod bracket 31 rotates towards the upper end face of the base 1, so that the pull rod device 3 is in a folded state, which makes it convenient to store and carry.

[0058] When needed, by rotating the first pull rod bracket 31 and the second pull rod bracket 32, the first pull rod bracket 31 rotates in a direction away from the upper end face of the base 1, and the position of the first pull rod bracket 31 and the second pull rod bracket 32 ​​is restricted by the rotation limiting mechanism 33, thereby realizing that the pull rod device 3 is in the unfolded state.

[0059] An clearance groove 11 is provided on the upper surface of the base 1. The front end of the clearance groove 11 passes through the front end of the base 1, and the rear end of the clearance groove 11 passes through the rear end of the base 1. The opening of the clearance groove 11 is set towards the upper end of the base 1. The lower end of the pull rod bracket 31 is placed in the clearance groove 11, and the lower end of the pull rod bracket 31 is hinged to the side wall of the clearance groove 11, so as to realize the rotational connection of the pull rod bracket 31 on the base 1.

[0060] Combination Figures 4-6 When the pull rod device 3 is in the folded state, that is, when both pull rod bracket 1 31 and pull rod bracket 2 32 are rotated into the clearance groove 11, that is, when pull rod bracket 1 31 rotates toward the front end of the base 1 and pull rod bracket 2 32 rotates toward the rear end of pull rod bracket 1 31, at this time, the front end of pull rod bracket 2 32 does not protrude from the upper surface of the base 1, so that the upper surface of the base 1 remains flat and is easy to store.

[0061] Combination Figure 3 and Figure 6 The upper end of the first tie rod bracket 31 has a connecting part 311, and the lower end of the second tie rod bracket 32 ​​has a connecting part 321. The first connecting part 311 and the second connecting part 321 are rotatably connected.

[0062] The rotation limiting mechanism 33 is a rotation limiting sleeve 331, which is slidably sleeved on the first connecting part 311 and the second connecting part 321, and the rotation limiting sleeve 331 is placed at the connection between the first connecting part 311 and the second connecting part 321 to limit the relative rotation between the first connecting part 311 and the second connecting part 321.

[0063] The tie rod bracket 31 in this technical solution has two connecting parts 311, and the tie rod bracket 32 ​​also has two corresponding connecting parts 321, and the connecting parts 311 and 321 are rod-shaped structures.

[0064] A limiting part 312 is provided on the connecting part 311. The limiting part 312 movably abuts against the lower end of the limiting sleeve 331 to restrict the movement of the limiting sleeve 331 on the connecting part 311, so as to prevent the limiting sleeve 331 from failing to maintain its position at the connection between the connecting part 311 and the connecting part 321 due to its own weight. In this design, the limiting part 312 is a horizontal bar, which is located between the two connecting parts 311, that is, each end of the horizontal bar is connected to a connecting part 311.

[0065] A connecting plate 34 is rotatably disposed between connecting part 1 311 and connecting part 2 321. One end of the connecting plate 34 is hinged to connecting part 1 311 by a hinge pin, and the other end of the connecting plate 34 is hinged to connecting part 2 321 by another hinge pin. Connecting part 1 311 is provided with a limiting part 313 and an arc-shaped part 314 at its end, and connecting part 2 321 is provided with a limiting part 322 and an arc-shaped part 323 at its end. The limiting part 313 corresponds to the limiting part 322, and the arc-shaped part 314 corresponds to the arc-shaped part 323.

[0066] The first limiting part 313 and the second limiting part 322 are in contact to limit the rotation of the first connecting part 311 and the second connecting part 321; the first arc-shaped part 314 and the second arc-shaped part 323 cooperate to enable the first connecting part 311 and the second connecting part 321 to rotate on the connecting plate 34, and the first limiting part 313 and the second limiting part 322 are close to the front end of the base 1, and the first arc-shaped part 314 and the second arc-shaped part 323 are close to the rear end of the base 1, so that the second pull rod bracket 32 ​​can rotate and fold towards the rear side close to the base 1.

[0067] In this technical solution, both the ends of the first connecting part 311 and the second connecting part 321 are provided with a connector, and the connector of the first connecting part 311 has a first limiting part 313 and a first arc-shaped part 314, and the connector of the second connecting part 321 has a second limiting part 322 and a second arc-shaped part 323.

[0068] The front side wall of the clearance groove 11 has an anti-detachment protrusion 111. When the tie rod bracket 31 rotates and is placed in the clearance groove 11 under the action of external force, the anti-detachment protrusion 111 abuts against the rear end of the tie rod bracket 31, thereby restricting the rotation of the tie rod bracket 31 in the clearance groove 11 and preventing the tie rod bracket 31 from leaving the clearance groove 11.

[0069] Combination Figure 2 , Figure 4 , Figure 7 and Figure 8The rear side wall of the clearance groove 11 has an anti-detachment protrusion 112. When the tie rod bracket 32 ​​rotates and is placed in the clearance groove 11 under the action of external force, the anti-detachment protrusion 112 abuts against the front end of the tie rod bracket 32, thereby restricting the rotation of the tie rod bracket 32 ​​in the clearance groove 11, preventing the tie rod bracket 32 ​​from leaving the clearance groove 11, and ensuring the stability of the tie rod device 3 in the folded state.

[0070] Combination Figures 1-3 This design scheme also includes:

[0071] Shopping bag 4, which is a cloth bag or mesh bag, can be deformed and folded. Shopping bag 4 is detachably installed on pull rod device 3, and the bottom of shopping bag 4 is movably abutted against base 1. Base 1 is used to support shopping bag 4.

[0072] The shopping bag 4 has an elastically deformable connecting strap 41 at its rear end. The connecting strap 41 and the shopping bag 4 are connected by a pull rod device 3. The pull rod device 3 is inserted between the connecting strap 41 and the shopping bag 4. Under its own elastic deformation, the connecting strap 41 restricts the shopping bag 4 to the pull rod device 3, thereby ensuring the stability of the shopping bag 4.

[0073] When storage is needed, the pull rod device 3 can be folded down so that the base 1, pull rod device 3, and wheel device 2 can be placed into the shopping bag 4 for easy storage and movement.

[0074] Combination Figures 2-4 The pull rod device 3 has an anti-detachment rod 35, and the shopping bag 4 is provided with an anti-detachment part 42. The anti-detachment part 42 is made of fabric. The rear end of the anti-detachment part 42 is connected to the shopping bag 4 by sewing, integral molding, Velcro, or magnetic adsorption. The front end of the anti-detachment part 42 is detachably connected to the shopping bag 4. The front end of the anti-detachment part 42 is connected to the shopping bag 4 by Velcro or magnetic adsorption, so that a fixed space 43 for fixing the anti-detachment rod 35 is formed between the anti-detachment part 42 and the shopping bag 4. That is, the anti-detachment part 42 can cover and wrap the anti-detachment rod 35, thereby restricting the anti-detachment rod 35 within the fixed space 43 between the anti-detachment part 42 and the shopping bag 4, thus ensuring the stability of the shopping bag 4.

[0075] Combination Figure 4 The base 1 has several anti-slip grooves 12 on its end face. The two side walls of the anti-slip grooves 12 are connected to the side walls of the clearance grooves 11. When the pull rod device 3 is in the folded state, the anti-detachment rod 35 is placed in the anti-slip groove 12, thereby ensuring the flatness of the upper end face of the base 1 and preventing the anti-detachment rod 35 from protruding from the upper end of the base 1 and increasing the storage space.

[0076] Combination Figure 3 and Figure 5The wheel device 2 includes a connecting rod 22 and two wheels 21. The connecting rod 22 passes through the rear end of the base 1, and each end of the connecting rod 22 is connected to a wheel 21. The lower end of the tie rod bracket 31 passes through the lower end of the clearance groove 11 and is hinged to the connecting rod 22.

[0077] Combination Figure 7 and Figure 8 The bottom of the clearance groove 11 is connected to the lower end of the base 1, so as to realize the rotation of the tie rod bracket 31 within the clearance groove 11;

[0078] In this technical solution, a connecting rod 22 is used to connect the tie rod frame 31 and the wheel 21, so that the tie rod frame 31 is hinged to the base 1. Alternatively, a separate hinge pin can be used to achieve the hinge between the tie rod frame 31 and the base 1.

[0079] like Figure 7 A limited rotation section 113 is formed at the rear end of the clearance groove 11. The limited rotation section 113 is located above the rear end of the hinge point (i.e., the connecting rod 22) between the tie rod frame 31 and the clearance groove 11. When the tie rod device 3 is in the extended state, that is, when the tie rod frame 31 is in... Figure 7 After being rotated clockwise and unfolded, the rotation limiting part 113 abuts against the rear side of the lower end of the pull rod frame 31 to limit the pull rod frame 31 from rotating toward the rear of the base 1, ensuring that the pull rod device 3 can pull the base 1 to move. The lower end of the rotation limiting part 113 is higher than the upper end of the hinge point (i.e., the connecting rod 22) between the pull rod frame 31 and the clearance groove 11, so that the pull rod frame 31 can be rotated and folded.

[0080] The shopping bag 4 is placed on the base 1, and the shopping bag 4 is located at the front end of the pull rod frame 31 and the pull rod frame 32. With the help of the rotation limiting part 113, the rotation of the pull rod frame 31 can be limited, so that the pull rod frame 31 can be kept in the unfolded state. There is no need to set up additional limiting parts, saving costs and improving production efficiency.

[0081] Combination Figures 1-3 A support foot 13 is provided on the lower front side of the base 1 to support the front end of the base 1. The support foot 13, together with the wheel 21, makes the base 1 stable when placed on the ground.

[0082] Combination Figures 1-3 The shopping bag 4 has a cover 44 and a drawstring 45 at the opening. The drawstring 45 is equipped with an adjustment buckle. The adjustment buckle is prior art. Please refer to Chinese Patent CN201921674229.8. It will not be described in detail here.

[0083] The specific work process of this plan is as follows:

[0084] When folding is required, remove the shopping bag 4, and then move the limiting sleeve 331 onto the pull rod bracket 32, so that the limiting sleeve 331 leaves the connecting part 311. At this time, rotate the pull rod bracket 32 ​​so that the rear end of the pull rod bracket 32 ​​is close to the rear end of the pull rod bracket 31, thereby folding the pull rod bracket 31 and the pull rod bracket 32. Then, rotate the front end of the pull rod bracket 31 toward the front end of the base 1 so that the pull rod bracket 31 is placed in the clearance groove 11, thereby putting the pull rod device 3 in a folded state. At this time, the anti-detachment protrusion 111 and the anti-detachment protrusion 112 can restrict the pull rod bracket 31 and the pull rod bracket 32 ​​within the clearance groove 11.

[0085] When it needs to be unfolded, external force causes the first pull rod bracket 31 and the second pull rod bracket 32 ​​to leave the clearance groove 11. The first pull rod bracket 31 rotates toward the rear end of the base 1, so that the rotation limiting part 113 abuts against the rear end of the first pull rod bracket 31. The second pull rod bracket 32 ​​rotates on the first pull rod bracket 31, so that the second limiting part 322 abuts against the first limiting part 313. At this time, the rotation limiting sleeve 331 is moved toward the first pull rod bracket 31, so that the lower end of the rotation limiting sleeve 331 is fitted onto the first connecting part 311. At this time, the limiting part 312 restricts the downward movement of the rotation limiting sleeve 331, so that the pull rod device 3 is in the unfolded state.

[0086] Example 2:

[0087] The design scheme of this embodiment is basically the same as that of Embodiment 1, except that:

[0088] See Figure 9 The rotation limiting part 113 is located below the front end of the hinge point (i.e., the connecting rod 22) between the tie rod bracket 31 and the clearance groove 11. When the tie rod device 3 is in the extended state, that is, when the tie rod bracket 31 is in... Figure 9 After being rotated clockwise and unfolded, the rear end of the rotation limiting part 113 abuts against the front end of the tie rod frame 31, thereby limiting the rotation of the tie rod frame 31.
