DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A novel double-layer pet stroller in this embodiment includes a mobile base 1. Two push rods 2 are arranged on the front side of the top of the mobile base 1. A bottom frame 3 is arranged on the top of the mobile base 1. A top frame 4 is arranged on the upper side of the bottom frame 3. An adjustment mechanism 5 is arranged at the bottom of the top frame 4. Space expansion mechanisms 6 are arranged on both the bottom frame 3 and the top frame 4.

[0022] The adjustment mechanism 5 includes a bidirectional screw rod 501 rotatably installed inside the mobile base 1, and the two ends of the outer surface of the bidirectional screw rod 501 are respectively threadedly connected with a movable sleeve 502, and the top of the two movable sleeves 502 are hinged with a connecting rod 503. A sliding groove 504 is provided at the bottom of the top frame 4, and a slider 505 connected to the top of the connecting rod 503 is slidably installed at the two ends of the inner part of the sliding groove 504.

[0023] Specifically, an anti-slip knob is fixedly installed on the right end of the bidirectional screw rod 501, and a circular hole is opened on the right side of the movable base 1 on the outer surface of the bidirectional screw rod 501. The right end of the bidirectional screw rod 501 passes through the circular hole and is connected to the anti-slip knob. The anti-slip knob is used to drive the bidirectional screw rod 501 to rotate to adjust the height of the top frame 4.

[0024] Specifically, the two connecting rods 503 are cross-distributed in a scissor-like manner, the bottom ends of the two connecting rods 503 are respectively hinged to the movable sleeves 502, and the top ends are respectively hinged to the sliders 505. Through the rotation of the bidirectional screw rod 501 and the rotation of the two connecting rods 503, the sliders 505 connected thereto are driven to slide in the slide grooves 504, thereby realizing the height adjustment of the top frame 4. It should be noted that in order to improve the stability of the top frame 4, a telescopic rod is arranged between the top of the bottom frame 3 and the bottom of the top frame 4, and the telescopic rod and the adjustment mechanism 5 are distributed between the bottom frame 3 and the top frame 4, one after the other.

[0025] The space expansion mechanism 6 includes an expansion frame 601 slidably installed on the left and right sides of the bottom frame 3 and the top frame 4, and two positioning holes 602 are respectively opened on the two expansion frames 601. The left and right ends of the front side of the bottom frame 3 and the top frame 4 are provided with positioning parts 603 corresponding to the two expansion frames 601.

[0026] The positioning member 603 includes a positioning rod 701 inserted into one of the positioning holes 602, a pull tab 702 is fixedly installed on one end of the positioning rod 701 away from the positioning hole 602, a limiting plate 703 is fixedly installed on the outer surface of the positioning rod 701, and a spring 704 is sleeved on the outer surface of the positioning rod 701.

[0027] Specifically, taking the bottom frame 3 as an example, the two expansion frames 601 can move left and right inside the bottom frame 3, and the position of the expansion frames 601 is locked by the positioning piece 603. When it is necessary to expand the internal storage space of the bottom frame 3, the two expansion frames 601 are pulled outward, and then the positioning rods 701 are inserted into the corresponding positioning holes 602 to fix the position of the expansion frames 601, thereby achieving the purpose of adjusting the internal storage space of the bottom frame 3, so that it is suitable for pets of different sizes.

[0028] When implementing, follow these steps:

[0029] 1) When adjusting the internal accommodation space of the bottom frame 3 or the top frame 4, first pull the two pull tabs 702 outward, the two pull tabs 702 drive the positioning rods 701 to move outward, and the two positioning rods 701 drive the two limiting plates 703 to be used synchronously, so that the spring 704 is compressed between the pull tabs 702 and the limiting plates 703. At this time, the two positioning rods 701 withdraw from the interior of the positioning holes 602 and contact the lock of the expansion frame 601;

[0030] 2) Then slide the two expansion frames 601 outward from the inside of the bottom frame 3 and the top frame 4, then release the two pull tabs 702, the spring 704 expands, and the two positioning rods 701 are inserted into the corresponding positioning holes 602, completing the adjustment of the internal space;

[0031] 3) When adjusting the distance between the bottom frame 3 and the top frame 4, firstly, the anti-slip knob is turned to drive the bidirectional screw rod 501 to rotate, and the bidirectional screw rod 501 drives the two movable sleeves 502 to move relative to each other, and the two movable sleeves 502 drive the two connecting rods 503 to rotate, and the two connecting rods 503 drive the two sliders 505 to slide relative to each other in the slide groove 504;

[0032] 4) Finally, adjust the top frame 4 to the required height.

[0033] In summary, the novel double-layer pet stroller can adjust the top frame 4 along the height direction of the bottom frame 3 by setting the adjustment mechanism 5, so as to change the distance between the top frame 4 and the bottom frame 3, thereby providing a more comfortable and suitable environment for the pet, and also meeting the different requirements of the pet owner for the use function of the stroller.

[0034] Furthermore, by providing the space expansion mechanism 6, the internal accommodation space of the bottom frame 3 and the top frame 4 can be adjusted, so that the stroller can adapt to pets of different sizes, thereby improving the flexibility and practicality of use.
