Now, a pet stroller bracket and a pet stroller thereof are provided.
[0004] The technical solution adopted by the utility model to solve its technical problem is: a pet stroller bracket includes a front frame, a rear frame, a first bracket, a second bracket, a first connecting rod and a second connecting rod. The front frame and the rear frame are arranged opposite to each other. One end of the first connecting rod and one end of the first bracket are both hinged to the front frame. The first connecting rod and the first bracket are respectively arranged opposite to each other at the upper end and the lower end of the front frame. One end of the second connecting rod and one end of the second bracket are both hinged to the rear frame. The second connecting rod and the second bracket are respectively arranged opposite to each other at the upper end and the lower end of the rear frame. The first bracket and the second bracket are arranged opposite to each other. The end of the first bracket away from the front frame is hinged to the end of the second bracket away from the rear frame. The first connecting rod and the second connecting rod are arranged opposite to each other. A radial locking mechanism for radially limiting the two to each other is arranged between the first connecting rod and the second connecting rod. A first limiting mechanism is arranged between the front frame and the rear frame. The first limiting mechanism is used to limit the displacement direction of the front frame approaching or departing from the rear frame. Compared with the prior art, in the storage process of this solution, first unlock the radial locking mechanisms of the first connecting rod and the second connecting rod and separate them from each other, and then control the relative rotation of the first bracket and the second bracket, and under the limiting action of the first limiting mechanism, the front frame and the rear frame approach each other relatively. The operation is simple and it is convenient to store the stroller.
[0005] To implement the first limiting mechanism, in some preferred embodiments, the first limiting mechanism includes a first limiting rod and a second limiting rod.
