Description

[Technical Field]

[0001] This utility model relates to a basket frame. [Background Technology]

[0002] Carrying baskets are common products used in daily life for holding items, such as pet carriers for carrying pets. A carrying basket generally consists of a basket frame and a fabric cover that fits over the frame. Current carrying basket frames are generally capable of unfolding or folding. For example, Chinese Patent Publication No. (CN221864070U) filed by the applicant in March 2024 discloses a carrying basket frame including a bottom support frame and an upper support frame. The upper and bottom support frames can be unfolded or folded via a transmission mechanism between them. The transmission mechanism includes a first transmission rod and a second transmission rod that cross and are hinged to each other. The lower end of the first transmission rod is hinged to the bottom support frame, and the upper end of the first transmission rod is hinged to a second sliding member on the upper support frame. The lower end of the second transmission rod is hinged to the first sliding member on the bottom support frame, and the upper end of the second transmission rod is hinged to the upper support frame. Therefore, during unfolding or folding, both the first and second sliding members need to slide simultaneously. However, in actual use, there is still a problem of uneven sliding, resulting in the entire carrying basket frame being inflexible in its unfolding or folding.

[0003] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a basket frame with a simple structure and convenient and smooth folding or unfolding operation.

[0005] This utility model is achieved through the following technical solution:

[0006] A basket frame, which can move from an unfolded position to a folded position after the locking device is unlocked, includes a bottom support frame and an upper support frame. A transmission mechanism is provided between the upper support frame and the bottom support frame, which can drive the bottom support frame to move closer to or away from the upper support frame. The transmission mechanism includes a first transmission rod and a second transmission rod that cross each other and are hinged at the intersection. The upper support frame is provided with a sliding member that can slide relative to it. The lower end of the first transmission rod is hinged to the bottom support frame, and the upper end of the first transmission rod is hinged to the sliding member. The upper end of the second transmission rod is hinged to the upper support frame, and a third transmission rod is provided between the lower end of the second transmission rod and the bottom support frame, which is hinged to both.

[0007] The transmission mechanism consists of two sets, located on the left and right sides of the upper support frame and the bottom support frame.

[0008] The bottom support frame includes a support base plate, on which a connecting rod is provided along its length. The lower end of the first transmission rod is hinged to the connecting rod, and the lower end of the third transmission rod is hinged to the connecting rod.

[0009] The upper support frame includes an annular frame, with a slide rail on the lower side of the annular frame. The upper end of the second transmission rod is hinged to the slide rail. The sliding member is a sliding sleeve fitted on the slide rail. The upper end of the first transmission rod is hinged to the sliding sleeve.

[0010] The locking device is located between the sliding sleeve and the slide rail. The locking device includes a locking hole on the sliding sleeve. The slide rail contains a deformable spring sheet. The spring sheet has a locking protrusion that can engage or disengage with the locking hole. The slide rail is provided with a fixed seat. The fixed seat has an operating block that can move relative to it and push the spring sheet to disengage the locking protrusion from the locking hole.

[0011] The spring sheet has a protruding post that passes through the side wall of the slide rail and enters the fixed seat. The operating block is rotatably connected to the fixed seat. The operating block has a pushing part that can push the protruding post when it is pressed, so that the locking protrusion disengages from the locking hole.

[0012] The annular frame is provided with a joint seat in the middle, and a first top rod and a second top rod that can rotate relative to it are provided on the joint seat. A first locking member that can lock the first top rod and one end of the annular frame is provided, and a second locking member that can lock the second top rod and the other end of the annular frame is provided.

[0013] The joint seat, located between the first and second canopy rods, is also rotatably connected to a handle for lifting the basket frame.

[0014] The bottom support frame is also equipped with multiple support seats that can support the basket frame on the ground.

[0015] There are four support seats, two of which are arranged side by side on the front side of the support base plate, and the other two are arranged on the rear side of the support base plate. The support base plate is provided with a locking mechanism that can install the basket frame onto the trolley frame. The locking mechanism includes a sliding block that can slide within each support seat. A latch is formed between the sliding block and the support base plate that can engage the basket frame with the trolley frame. The two sliding blocks located on the same side of the support base plate are provided with operating rods that can pull the two blocks to slide simultaneously. A spring is also provided between the support seat and the sliding block that can push the sliding block to slide back to its original position.

[0016] Compared with the prior art, this utility model has the following advantages: When the basket frame of this utility model needs to be folded, the locking device is first unlocked, allowing the sliding member on the upper support frame to slide along it. During the sliding process, the sliding member drives the intersecting first and second transmission rods to rotate relative to each other. The first transmission rod rotates relative to the sliding member and the bottom support frame, the second transmission rod rotates relative to the third transmission rod, and the lower end of the third transmission rod rotates relative to the bottom support frame. This allows the first and second transmission rods to pull the bottom support frame upwards towards the upper support frame, thus achieving the folding of the basket frame. When the basket frame needs to be unfolded, simply lift the upper support frame upwards and slide the sliding member in the opposite direction to allow the folded first and second transmission rods to rotate relative to each other and open up. During this process, the second and third transmission rods rotate relative to each other, and the third transmission rod also rotates relative to the bottom support frame, opening up the bottom support frame and realizing the unfolding of the basket frame. The entire basket frame has a simple structure, supported by a cross first and second transmission rod, which has a strong load-bearing capacity. Furthermore, a third transmission rod is set between the second transmission rod and the bottom support frame, which are hinged to each other. Only the sliding parts on the upper support frame are allowed to slide, so that the basket frame can be folded or unfolded by simply sliding the sliding parts on the upper support frame. The folding or unfolding operation is convenient and smooth, and the unfolding or closing action is flexible and without jamming. [Attached Image Description]

Detailed Implementation Methods

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 5 As shown, a basket frame can be moved from an unfolded position to a folded position after the locking device is unlocked. A fabric cover is attached to the outside of the basket frame to form a basket capable of holding items, such as a pet carrier. In the unfolded position, a pet can be carried, while in the folded position, it is convenient for carrying or storage.

[0028] like Figures 1 to 5 As shown, the basket frame includes a bottom support frame 1 and an upper support frame 2. A transmission mechanism 3 is provided between the upper support frame 2 and the bottom support frame 1, which can drive the bottom support frame 1 to move closer to or away from the upper support frame 2. There are two sets of transmission mechanisms 3, located on the left and right sides of the upper support frame 2 and the bottom support frame 1. The transmission mechanism 3 includes a first transmission rod 31 and a second transmission rod 32 that cross each other and are hinged at the intersection. The upper support frame 2 is provided with a sliding member 34 that can slide relative to it. The lower end of the first transmission rod 31 is hinged to the bottom support frame 1, and the upper end of the first transmission rod 31 is hinged to the sliding member 34. The upper end of the second transmission rod 32 is hinged to the upper support frame 2. A third transmission rod 33 is provided between the lower end of the second transmission rod 32 and the bottom support frame 1, and is hinged to both.

[0029] like Figures 1 to 5 As shown, when the basket frame needs to be folded, the locking device is first unlocked, allowing the sliding member 34 on the upper support frame 2 to slide along it. During the sliding process, the sliding member 34 drives the intersecting first transmission rod 31 and second transmission rod 32 to rotate relative to each other. The first transmission rod 31 rotates relative to the sliding member 34 and the bottom support frame 1, while the second transmission rod 32 rotates relative to the third transmission rod 33. The lower end of the third transmission rod 33 rotates relative to the bottom support frame 1, thus enabling the first transmission rod 31, the second transmission rod 32, and the third transmission rod 33 to pull the bottom support frame 1 upwards towards the upper support frame 2, thereby achieving the folding of the basket frame. When the basket frame needs to be unfolded, simply lift the upper support frame 2 upwards and slide the sliding member 34 in the opposite direction to allow the folded first transmission rod 31 and second transmission rod 32 to rotate relative to each other and open up. During this process, the second transmission rod 32 rotates relative to the third transmission rod 33, and the third transmission rod 33 also rotates relative to the bottom support frame 1, thus opening up the bottom support frame 1 and achieving the unfolding of the basket frame. The entire basket frame has a simple structure, with only the sliding part 34 on the upper support frame 2 remaining. This allows the basket frame to be folded or unfolded by simply sliding the sliding part 34 on the upper support frame 2. The folding or unfolding operation is convenient and smooth, and the unfolding or closing action is flexible and without jamming.

[0030] like Figures 1 to 5As shown, the bottom support frame 1 includes a support base plate 11, on which a connecting rod 12 is provided along its length. The lower end of the first transmission rod 31 is hinged to the connecting rod 12, and the lower end of the third transmission rod 33 is hinged to the connecting rod 12. The support base plate 11 is a plate-shaped structure and is located at the bottom of the fabric cover, providing sufficient bottom support for the basket.

[0031] like Figure 1 As shown, the upper support frame 2 includes an annular frame 21, the lower side of the annular frame 21 is provided with a slide rail 22, the upper end of the second transmission rod 32 is hinged to the slide rail 22, the sliding member 34 is a sliding sleeve sleeved on the slide rail 22, and the upper end of the first transmission rod 31 is hinged to the sliding sleeve.

[0032] like Figure 5 and Figure 6 As shown, the locking device is located between the sliding sleeve and the slide rail 22. The locking device includes a locking hole 41 on the sliding sleeve. The slide rail 22 is provided with a deformable spring plate 42. The spring plate 42 is provided with a locking protrusion 43 that can engage or disengage from the locking hole 41. The slide rail 22 is provided with a fixed seat 23. The fixed seat 23 is provided with an operating block 44 that can move relative to it and push the spring plate 42 to disengage the locking protrusion 43 from the locking hole 41. The spring plate 42 is provided with a protruding post 45 that passes through the side wall of the slide rail 22 and enters the fixed seat 23. The operating block 44 is rotatably connected to the fixed seat 23. The operating block 44 is provided with a pushing part 46 that can push the protruding post 45 to disengage the locking protrusion 43 from the locking hole 41 when it is pressed. When the basket frame needs to be folded, press the operating block 44. The pushing part 46 on the operating block 44 pushes the protruding post 45 on the spring plate 42, causing the spring plate 42 to deform. The locking protrusion 43 on the spring plate 42 then disengages from the locking hole 41 on the sliding sleeve, unlocking the locking device. The sliding sleeve can then slide relative to the slide rail 22. During the sliding process, the sliding sleeve drives the first transmission rod 31 and the second transmission rod 32 to rotate relative to each other. The second transmission rod 32 then drives the third transmission rod 33 to rotate, thereby causing the upper support frame 2 and the bottom support frame 1 to fold together. When the basket frame is unfolded, as long as the sliding sleeve slides to the position where the locking hole 41 and the locking protrusion 43 are aligned, the locking protrusion 43 engages in the locking hole 41, thus maintaining the unfolded state of the basket frame.

[0033] like Figure 1As shown, the annular frame 21 has a joint seat 24 in the middle. The joint seat 24 has a first canopy rod 51 and a second canopy rod 52 that can rotate relative to it. A handle 8 for lifting the basket frame is rotatably connected to the joint seat 24, located between the first canopy rod 51 and the second canopy rod 6. A first locking element 71 is provided between the first canopy rod 51 and one end of the annular frame 21, and a second locking element 72 is provided between the second canopy rod 52 and the other end of the annular frame 21, also capable of locking them. The first canopy rod 51 and the second canopy rod 52 can support a flexible canopy that can block sunlight or wind. When both the first locking element 71 and the second locking element 72 are locked, the opening of the basket is completely closed. When either the first locking element 71 or the second locking element 72 is unlocked, the opening of the basket can be opened by lifting either the first canopy rod 51 or the second canopy rod 52, facilitating the loading and unloading of items. The first locking component 71 and the second locking component 72 can adopt a traditional locking structure with a latch and a hole, which will not be described in detail here.

[0034] like Figure 3 as well as Figures 7 to 9As shown, the bottom support frame 1 is also equipped with multiple support seats 10 to support the basket frame on the ground, making it convenient for users to place the basket on the ground. There are four support seats 10, two of which are arranged side by side on the front side of the support base plate 11, and the other two are arranged on the rear side of the support base plate 11. The support base plate 11 is equipped with a locking mechanism for installing the basket frame onto the trolley frame. The locking mechanism includes a sliding block 61 that can slide within each support seat 10. A latch 62 is formed between the sliding block 61 and the support base plate 11 to engage the basket frame onto the trolley frame. The two sliding blocks 61 located on the same side of the support base plate 11 are equipped with operating rods 63 that can pull them to slide simultaneously. A spring 64 is also provided between the support seat 10 and the sliding block 61 to push the sliding block 61 to slide back to its original position. When the latch 62 between the sliding block 61 and the support base plate 11 is engaged with the rod on the trolley frame, the basket can be installed and fixed onto the trolley frame, and the user can move the basket by pushing the trolley. When it is necessary to remove the basket, simply pull the operating lever 63 to slide the two sliding blocks 61 on the same side backward. At this time, the sliding block 61 on that side will no longer be caught on the rod of the trolley frame, and the basket on that side can rotate upward and disengage from the rod. Once disengaged, the basket can be pushed to disengage the latch 62 on the other side from the rod on the trolley frame, and the entire basket can be removed. Therefore, the basket can be easily removed regardless of whether the operating lever 63 on the front or rear side of the support base plate 11 is pulled. Of course, in order to make it convenient and quick to install the basket onto the trolley frame, an inclined surface 65 is provided on the lower side of the sliding block 61. Therefore, when installing the basket onto the trolley frame, simply press the basket down, and the inclined surface 65 will contact the rod on the trolley frame to push the sliding block 61 to slide. Once the basket is pressed down to the set position, the spring 64 pushes the sliding block 61 to slide back to its original position, forming the latch 62 again to lock the rod on the trolley frame, thus locking the basket onto the trolley frame.

[0035] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
