Description

Technical field

[0001] The invention relates to the technical field of pet strollers and, in particular, to a folding basket device for use with a pet stroller. Technical background

[0002] Pet strollers are a novel tool for traveling with pets. Pet strollers have a wide range of uses. With a stroller, users can take their senior dogs outside for some fresh air, so they don't have to stay depressed at home every day, especially when no one is home. Furthermore, pet owners know that pets are prohibited in public places like supermarkets, shopping malls, and even indoors at some tourist attractions. Although regulations prohibit pets (except for guide dogs), they are allowed to be carried in travel bags or strollers. In such cases, pet strollers come in handy. In fact, many shopping malls in China also offer pet strollers.

[0003] Due to their small size, dogs are often kicked or bumped when walking on the ground in crowded places. For anxious or sensitive dogs, a stroller can prevent the dog from direct contact with other people or pets, and prevent them from eating things on the sidewalk. The most important parts of existing pet strollers are the stroller body and the basket body for carrying the pet. However, the existing basket bodies are all fixed structures and cannot be used with the folding stroller, which affects the travel and carrying of people.

[0004] Therefore, the urgent task of professionals is to provide a folding basket device for use with a pet stroller. Subject of the utility model

[0005] Against this background, the present application provides a folding basket device for use with a pet stroller that is convenient to fold and use and can be easily carried when traveling.

[0007] The technical effect of the present application is that the down tube frame and the up tube frame cooperate with the deformation support mechanism to form a frame base for the deformation and folding of the basket body. The control mechanism is used to control the state of the locking assembly extending inward and outward from the guide portion, thereby controlling the deformation of the deformation support mechanism. It should be understood that when the locking assembly is controlled and retracted into the guide portion by the control mechanism, the deformation support mechanism can be folded, which is convenient to carry in this state.When the basket body is in use, the deformation support mechanism is extended, and the locking assembly is used to extend and position the deformation support mechanism, ensuring the normal use of the basket body. In addition, the lifting handle is designed to facilitate the carrying of the basket body, and the canopy support rod is foldable and deformable, which is used to open and fold the canopy, which is convenient for accommodating pets in public places.

[0008] It is preferable that the down tube frame and the lift tube frame are both square ring structures and the control mechanism is located in the middle of one end of the down tube frame.

[0009] The resulting technical effect is that a user can control the shape of the locking assembly to unlock the deformation assist mechanism by operating the control mechanism from one end.

[0010] It is preferred that the control mechanism comprises a fixed seat, a buckle, a guide post, and a pull rope, wherein the fixed seat is fixed to the center of one end of the down tube frame, the buckle is hinged to the fixed seat and is located on the outside of the down tube frame, the guide post is fixed to the fixed seat and is located on the inside of the down tube frame, and a side wall of the down tube frame is provided with an escape groove through which the escape rope and the guide post pass, wherein one end of the pull rope is connected to the buckle and the other end, after being passed through the guide post, is connected to the locking assembly. The resulting technical effect is that the buckle sits firmly on the fixed seat in the static state due to the tension of the pull rope.
