[0025] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0026] like Figure 1-3 As shown, this utility model provides a convenient pet stroller, including a stroller frame 1. Four movable wheels 2 are movably connected to the bottom corners of the stroller frame 1. A pet carrier 3 is provided on the inner surface of the stroller frame 1. A large cloth cover 4 is provided on the top of the pet carrier 3, which is closed by a zipper. A ventilation hole 5 is provided on the right side of the top of the large cloth cover 4, and a small cloth cover 6 is provided on the left side of the top of the large cloth cover 4, which is closed by Velcro to the ventilation hole 5. The stroller frame 1 includes two support frames 11, with four telescopic sliding pillars 12 slidably inserted at the opposite ends of the two support frames 11. Two positioning mechanisms 13 are provided on the front and rear sides of the outer surface of the support frames 11. Several support columns 14 are fixedly connected to the bottom of the opposite sides of the two support frames 11, and the support columns 14 are staggered left and right, with several on the same side... A connecting slide plate 15 is fixedly connected to one end of a support column 14 away from the support frame 11. The middle part of the connecting slide plate 15 is slidably connected to the outer surface of the support column 14 on the same side. A push frame 16 is fixedly connected to the top of the support frame 11 on the left side. The positioning mechanism 13 includes a knob 131, which is movably connected to the outside of the support frame 11. A threaded column 132 is fixedly connected to the side of the knob 131 near the support frame 11. Two threaded holes are opened on both the front and rear sides of the support frame 11. The outer surface of the threaded column 132 is threadedly connected to the inner surface of the threaded hole. A positioning insert 133 is fixedly connected to one end of the threaded column 132 away from the knob 131. Several positioning slots 121 are opened on the side of the telescopic slide column 12 away from the pet box 3. The ends of the positioning inserts 133 away from the threaded column 132 all penetrate into the interior of the positioning slots 121.

[0027] When using the pet stroller, the pet is placed in the pet carrier 3, which is then placed in the stroller frame 1. The pet carrier 3 can be closed using the large cover 4, and the head can be easily extended through the ventilation hole 5. The ventilation hole 5 can be closed using the small cover 6. The stroller frame 1 can then be moved by pushing the push frame 16, which moves the stroller frame 1 via the moving wheels 2, making it convenient to take the pet out. The distance between the two support frames 11 can be adjusted by sliding between the support column 14 and the connecting slide plate 15, and the telescopic slide column 12 can extend and retract between the two support frames 11. At the same time, by turning the knob 131, the threaded column 132 can be screwed into the threaded hole, so that the positioning column 133 can be inserted into the positioning slot 121, which can fix the support frame 11 and the telescopic slide column 12, thus fixing the size of the stroller frame 1 after adjustment. This makes it convenient to place and support pet carriers 3 of different sizes, making it easier to carry pets of different sizes and making the pet stroller more convenient to use.

[0028] like Figure 4-5As shown, this utility model provides a convenient pet stroller. The push frame 16 includes a push column 161, which is fixedly connected to the top of the left support frame 11. Connecting grooves are provided on both the front and rear sides of the bottom of the outer surface of the push column 161. A pull plate 162 is slidably connected inside the connecting grooves. One end of the pull plate 162 near the support frame 11 extends into the interior of the support frame 11 and is fixedly connected to a pull column 163. A sliding groove is provided on the bottom of both the front and rear sides of the support frame 11. The bottom end of the pull column 163 extends into the sliding groove and is fixedly connected to a sliding pull plate 164. The side of the sliding pull plate 164 away from the pull column 163 is slidably connected to the side of the moving wheel 2 near the support frame 11. Positioning blocks 21 are arranged in a circular array on the side of the moving wheel 2 near the support frame 11. A locking block 165 is fixedly connected above the side of the sliding pull plate 164 near the moving wheel 2. A top plate is fixedly connected to the top of the sliding pull plate 164. A tension spring 166 is provided on the outer surface of the pull column 163. The pull plate 162 includes a connecting slider 1621, which is slidably connected to the inside of the first sliding groove. The inside of the connecting slider 1621 is provided with a second sliding groove. The inside of the second sliding groove is slidably connected with a limiting slide plate 1623. A trapezoidal block 1622 is fixedly connected to the side of the limiting slide plate 1623 away from the support frame 11. Two positioning slots are provided on the inner wall of the first sliding groove away from the support frame 11. One end of the trapezoidal block 1622 away from the limiting slide plate 1623 extends into the inside of the positioning slot. A push spring 1624 is fixedly connected to the side of the limiting slide plate 1623 away from the trapezoidal block 1622. A push plate 1625 is movably connected to the bottom of the trapezoidal block 1622. A pressing column 1626 is movably connected to the bottom end of the push plate 1625. The bottom end of the pressing column 1626 extends to the bottom outer side of the connecting slider 1621.

[0029] When the pet stroller is in use, pulling the pull plate 162 causes the pull column 163 to slide, allowing the sliding pull plate 164 to slide inside the sliding groove. This allows the locking block 165 to lock the positioning block 21, restricting the rotation of the moving wheel 2 and braking the pet stroller. Under the push of the push spring 1624, the limiting slide plate 1623 pushes the trapezoidal locking block 1622 into the positioning slot, fixing the position of the pull plate 162 and effectively positioning the pet stroller, preventing it from sliding automatically. Then, pressing the pressing column 1626 causes the push plate 1625 to push the trapezoidal locking block 1622 back, facilitating the reset of the sliding pull plate 164 and the locking block 165 under the push of the tightening spring 166. This makes it easier to push the pet stroller again, making it more convenient to use.

[0030] The working principle of this portable pet stroller will be explained in detail below.

[0031] like Figure 1-5 As shown, when the pet stroller is in use, the distance between the left and right support frames 11 can be adjusted by sliding the support column 14 and the connecting slide plate 15, and the telescopic slide column 12 can extend and retract between the two support frames 11. At the same time, by rotating the knob 131, the threaded column 132 can be screwed into the threaded hole, thereby allowing the positioning insert 133 to be inserted into the positioning slot 121, which can fix the telescopic slide column 12 and fix the size of the stroller bracket 1 after adjustment. This facilitates the placement and support of pet carriers 3 of different sizes. Afterwards, the pet is placed in the pet carrier 3 and covered by the large cloth cover 4. The pet carrier 3 can be closed, and the head can be easily extended through the ventilation hole 5. The ventilation hole 5 can be closed through the small cloth cover 6. Then, by pushing the push frame 16, the stroller bracket 1 can be moved through the moving wheels 2, which is convenient for taking the pet out. At the same time, by pulling the pull plate 162, the pull column 163 can be driven to slide the sliding pull plate 164, so that the locking block 165 can lock the positioning block 21, thereby restricting the rotation of the moving wheels 2, realizing the braking of the pet stroller, effectively positioning the pet stroller, preventing the pet stroller from automatically sliding, and making the pet stroller more convenient to use.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
