Technical Field
[0001] This utility model belongs to the field of pet supplies handle technology, and specifically relates to a stroller in which the basket and frame can be folded and closed in conjunction. Background Technology
[0002] The original design purpose of this product was to solve the safety problem of taking pets out. With the rising living standards of people, more and more people are keeping pets for emotional support and taking them out with them. However, using a pet leash to control and lead pets when traveling presents several safety risks, affecting not only the safety of the pet but also the safety of people around the pet. Strollers with pet carriers can effectively solve the problem of taking pets out. Pet carriers are usually used together with the stroller frame. The pet is placed in the carrier and then the carrier is fixed to the frame, making it convenient for people to push the stroller.
[0003] In existing technology, the pet carrier of a pet stroller is usually detachable from the stroller frame. The stroller can only be folded up by disassembling the pet carrier and folding up the stroller frame separately. It cannot be folded up when the pet carrier is fixed to the stroller frame. This results in many steps to folding up the stroller, complicated operation buttons, and inconvenience when storing and carrying it out, which is not conducive to the promotion of the stroller. Utility Model Content
[0004] The main objective of this invention is to provide a trolley in which the basket and frame can be folded and closed in conjunction. The push rod assembly includes: a push rod body, a support drive rod with one end rotatably connected to the push rod body and the other end connected to the rear of a fixed joint, and a base plate drive rod with one end rotatably connected to the push rod body and the other end rotatably connected to the bottom of the fixed joint. One end of the upper part of the basket is rotatably mounted on the push rod body, and one end of the bottom of the basket base is slidably mounted on the base plate drive rod, with the other end rotatably mounted on the front wheel bracket. During folding, the push rod body drives the support drive rod and the base plate drive rod to press down and fit against the rear wheel bracket. Simultaneously, the push rod body drives one end of the upper part of the basket to press down, the support drive rod drives the folding bracket to fold, causing the other end of the upper part of the basket to fold closer to the basket base. The base plate drive rod drives one end of the basket base to press down while simultaneously causing one end of the basket base to rotate relative to the front wheel bracket. The above solution overcomes the drawback of traditional strollers where the stroller frame and pet carrier need to be folded and folded separately to complete the stroller's folding and folding. It allows the carrier to be folded and folded at the same time as the stroller, reducing the number of steps and making the operation simple and quick. This is beneficial for users to store and carry the stroller when going out, and promotes the widespread adoption of strollers.

[0025] The original design purpose of this product was to solve the safety problem of taking pets out. With the rising living standards of people, more and more people are keeping pets for emotional support and taking them out with them. However, using a pet leash to control and lead pets when traveling presents several safety risks, affecting not only the safety of the pet but also the safety of people around the pet. Strollers with pet carriers can effectively solve the problem of taking pets out. Pet carriers are usually used together with the stroller frame. The pet is placed in the carrier and then the carrier is fixed to the frame, making it convenient for people to push the stroller.
[0026] In existing technology, the pet carrier of a pet stroller is usually detachable from the stroller frame. The stroller can only be folded up by disassembling the pet carrier and folding up the stroller frame separately. It cannot be folded up when the pet carrier is fixed to the stroller frame. This results in many steps to folding up the stroller, complicated operation buttons, and inconvenience when storing and carrying it out, which is not conducive to the promotion of the stroller.
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model embodiment provides a trolley in which the basket and frame can be linked and folded together. It includes: a trolley frame 10 and a basket assembly 20 installed on the trolley frame 10. The trolley frame 10 includes: a fixed joint 11, a rear wheel bracket 12 installed at the bottom of the fixed joint 11, a front wheel bracket 13 rotatably installed at the front of the fixed joint 11, a push rod assembly 14 rotatably installed at the upper part of the fixed joint 11, and a front wheel drive bracket 15 rotatably connected to the front wheel bracket 13, the rear wheel bracket 12 and the push rod assembly 14 respectively. The basket assembly 20 includes: a basket upper part 21, a basket bottom plate 22, and a folding bracket 23 rotatably connected to the basket upper part 21, the fixed joint 11 and the push rod assembly 14 respectively.
[0028] The push rod assembly 14 includes: a push rod body 141, a bracket drive rod 142 with one end rotatably connected to the push rod body 141 and the other end connected to the rear of the fixed joint 11, and a base plate drive rod 143 with one end rotatably connected to the push rod body 141 and the other end rotatably connected to the bottom of the fixed joint 11. One end of the upper part 21 of the basket is rotatably mounted on the push rod body 141. One end of the bottom of the basket base plate 22 is slidably mounted on the base plate drive rod 143 and the other end is rotatably mounted on the front wheel bracket 13. The front wheel drive bracket 15 is rotatably connected to the front wheel bracket 13, the rear wheel bracket 12 and the bracket drive rod 142 respectively.
[0029] During the folding process, while the push rod body 141 drives the bracket drive rod 142 and the base plate drive rod 143 to press down and fit against the rear wheel bracket 12, the push rod body 141 drives one end of the upper part 21 of the basket to press down, and the bracket drive rod 142 drives the folding bracket 23 to fold, causing the other end of the upper part 21 of the basket to move closer to the bottom plate 22 of the basket. At the same time, the bracket drive rod 142 drives the front wheel drive bracket 15 to rotate and fit against the rear wheel bracket 12, and the base plate drive rod 143 drives one end of the bottom plate 22 of the basket to press down, causing one end of the bottom plate 22 of the basket to rotate relative to the front wheel bracket 13, thereby completing the folding and closing of the trolley.
[0030] During the unfolding process, the push rod body 141 is driven to move in the opposite direction, causing the bracket drive rod 142 and the base plate drive rod 143 to unfold away from the rear wheel bracket 12. The push rod body 141 drives one end of the upper part 21 of the basket to rise. The bracket drive rod 142 drives the folding bracket 23 to fold, causing the other end of the upper part 21 of the basket to unfold away from the bottom plate 22 of the basket. At the same time, the bracket drive rod 142 drives the front wheel drive bracket 15 to rotate and unfold the front wheel bracket 13 away from the rear wheel bracket 12. The base plate drive rod 143 drives one end of the bottom plate 22 of the basket to rise away from the bottom plate 22, while simultaneously causing the other end of the bottom plate 22 of the basket to rotate relative to the front wheel bracket 13, thereby completing the unfolding of the trolley.
[0031] In this utility model, the above solution overcomes the disadvantage that the traditional stroller frame 10 and pet carrier need to be folded and folded separately to complete the folding and folding of the stroller. When the stroller frame 10 is folded and folded, the carrier assembly 20 can also be folded and folded at the same time, which reduces the folding and folding steps of the stroller, makes the operation simple and quick, and is conducive to the user's storage and carrying when going out. It is also conducive to the promotion of strollers.
