[0031] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0032] Please refer to Figures 1 to 3 A foldable pet stroller includes a frame, the frame including a telescopic push rod, a front leg bar 3, a rear leg bar 4, a support bar 41, and a platform frame 5.

[0033] The push rod includes an upper push rod 1 and a lower push rod 2. The upper push rod 1 can slide into the lower push rod 2, and the upper push rod 1 is provided with a push rod locking pin 12, a push rod spring 13, a retraction button 14 and a traction line 15.

[0034] Please refer to Figure 4 Specifically, the upper push rod 1 has a push handle 11 at one end, the retraction button 14 has a bent structure, and the bent part of the retraction button 14 is hinged to the push handle 11. One end of the traction line 15 extends from the end of the retraction button 14 away from the bent part and is fixed to the retraction button 14. The other end of the traction line 15 is fixed to the push rod latch 12.

[0035] The upper push rod 1 has a first slot, and the lower push rod 2 has a second slot corresponding to the first slot. One end of the push rod pin 12 extends out of the first slot and into the third slot. At this time, the upper push rod 1 and the lower push rod 2 are relatively fixed in position. The push rod spring 13 is used to provide the force to keep the push rod pin 12 extended into the second slot.

[0036] When the retraction button 14 is pressed, the traction line 15 is forced to rise, causing the push rod latch 12 to disengage from the first slot. At this time, the upper push rod 1 and the lower push rod 2 can slide freely up and down to achieve the effect of extension and retraction. In addition, a return spring 17 is provided on the side of the retraction button 14 away from the traction line 15, which is used to keep the retraction button 14 in the reset state when no external force is received, so that the traction line 15 is not lifted by the retraction button 14, and the push rod latch 12 is locked in place.

[0037] The lower end of the push rod is provided with a first fixed seat 21, and the upper end of the front foot rod 3 is provided with a second fixed seat 31. The push rod and the first fixed seat 21 can slide relative to the second fixed seat 31 along the axial direction of the front foot rod 3. The lower end of the push rod is provided with a locking member, which is used to limit the relative position of the front foot rod 3 and the push rod.

[0038] Specifically, the locking mechanism includes a front foot latch 32 and a locking spring 33. Both the front foot latch 32 and the locking spring 33 are located inside the upper end of the front foot rod 3. A third slot is provided on the lower push rod 2, and a fourth slot is provided on the front foot rod 3. One end of the front foot latch 32 extends out from the third slot and into the fourth slot. The locking spring 33 is used to provide a force to keep the front foot latch 32 inserted into the third slot. A collision plug 16 is provided at one end of the upper push rod 1 that extends into the lower push rod 2. The collision plug 16 is used to push the front foot latch 32 out of the third slot.

[0039] The locking spring 33, in conjunction with the front foot latch 32, secures the lower push rod 2 and the front foot lever 3 for normal use. When folding is required, the upper push rod 1 and the lower push rod 2 are unlocked, allowing the upper push rod 1 to slide down the interior of the lower push rod 2. At this time, the impact plug 16 at one end of the upper push rod 1 strikes the front foot latch 32, causing the front foot latch 32 to compress the locking spring 33 and retract into the front foot lever 3. This allows the lower push rod 2 to slide along the front foot lever 3, achieving the retraction of the front foot lever 3 and the lower push rod 2. When normal use is required, the lower push rod 2 is slid and extended along the front foot lever 3, causing the front foot latch 32 to pop out under the force of the locking spring 33 after being unrestricted by the lower push rod 2, thus achieving the locking purpose.

[0040] The above structure enables the upper push rod 1 and the lower push rod 2, as well as the lower push rod 2 and the front foot rod 3 to be stored in two sections, and achieves the purpose of linkage between the three, making it more convenient for people to use.

[0041] The rear support bar 4 includes a bent bar and a crossbar. The bent bar includes two support segments arranged in a V-shape. The crossbar is fixedly connected to the two support segments. The upper end of the bent bar is hinged to the first fixed seat 21. One end of the support bar 41 is hinged to the second fixed seat 31, and the other end is hinged to the crossbar.

[0042] The platform frame 5 is fixed with a front connecting block 51 and a rear connecting block 52 on both sides respectively. The front connecting block 51 is hinged to one end of the support member 53, and the other end of the support member 53 is hinged to the first fixed seat 21. The rear connecting block 52 is hinged to the second fixed seat 31.

[0043] In the above structure, the hinge point between the support rod 41 and the second fixed seat 31 is A, the hinge point between the support rod 41 and the crossbar is B, the hinge point between the rear foot rod 4 and the first fixed seat 21 is C, the hinge point between the first fixed seat 21 and the support member 53 is D, the hinge point between the support member 53 and the front connecting block 51 is E, and the hinge point between the rear connecting block 52 and the second fixed seat 31 is F.

[0044] Please refer to Figure 5 When the push rod 2 slides along the front foot rod 3, the distance between the first fixed seat 21 and the second fixed seat 31 increases, thereby causing the hinge points A, B, C, D, E, and F to rotate synchronously, so that the rear foot rod 4, the support member 53, and the platform frame 5 fit against the front foot rod 3, thereby achieving the folding effect.

[0045] Please refer to Figure 6 Basket 6, with a fixing component at the bottom, is detachably connected to platform frame 5.

[0046] Specifically, the fasteners include a hook 61 and a buckle seat 62. The hook 61 has an open hanging platform, and the buckle seat 62 is equipped with a buckle 63 and a buckle spring 64. The buckle 63 can slide on the buckle seat 62, and the buckle 63 is snapped back and locked by the buckle spring 64. The wrapping opening space formed by the hook 61 and the buckle 63 is the same size as the platform frame 5.

[0047] During installation, the buckle 63 is first slid on the buckle seat 62, creating space between the buckle 63 and the buckle seat 62 for one end of the platform frame 5 to be engaged. When the buckle 63 is released, the buckle 63, together with the buckle seat 62, tightens and fixes one side of the platform frame 5, while the other end of the platform frame 5 is engaged in the open hanging platform of the hook 61.

[0048] Please refer to Figure 7 , Figure 8 and Figure 9 The upper edge of the basket 6 is wrapped with a basket tube 65, and a handle tube 71 is hinged to the middle of the basket tube 65 through a combination seat 7. The combination seat 7 can lock the handle tube 71 to a set angle.

[0049] Specifically: A handle seat 72 is rotatably provided on the outer side of the combination seat 7. The handle seat 72 is fixedly connected to the handle tube 71. The handle seat 72 has a handle top hole 721 and a handle seat groove 722. A handle locking pin 73 and a handle spring 74 are also provided between the handle seat 72 and the combination seat 7. The handle locking pin 73 is slidably arranged along the axial direction of the combination seat 7, and part of the handle locking pin 73 is arranged in the handle seat groove 722. The handle spring 74 is used to push the handle locking pin 73 into the handle seat groove 722. A button 75 is provided on the outer side of the combination seat 7 and is slidably connected along the axial direction. The button 75 has a button top post 751, which is set corresponding to the handle top hole 721.

[0050] When button 75 is pressed down, button top post 751 presses handle locking pin 73 through handle top hole 721, causing handle locking pin 73 to be completely pushed out of handle seat slot 722. Thus, handle seat 72 can rotate without being restricted by the locking position, realizing the lowering or raising of handle tube 71. After the rotation is completed, the force of pressing button 75 is removed, and handle locking pin 73 is pushed out again and locked into handle seat slot under the action of handle spring 74, realizing the limiting and fixing of handle tube 71.

[0051] Furthermore, a sail seat 76 is provided on the inner side of the combination seat 7. The sail seat 76 is rotatably connected to the combination seat 7. The outer side of the sail seat 76 is fixed to the sail 77. The sail 77 is set above the basket 6. The sail 77 is used to drive the rotation of the covering cloth to achieve the covering and protection of the basket 6.

[0052] A sail retainer 78 and a sail spring 79 are provided between the sail holder 76 and the combination seat 7. The combination seat 7 has a combination seat groove for the sail retainer 78, and the sail retainer 78 is partially set in the combination seat groove. The sail holder 76 has a sail holder groove. The sail spring 79 is used to push the sail retainer 78. The handle retainer 73 has a retainer top post 731 on the side near the combination seat 7. The retainer top post 731 can pass through the combination seat 7 and press against the sail retainer 78.

[0053] Similarly, when button 75 is pressed, the handle latch 73 will slide towards the inside of the combination seat 7. The latch pin top post 731 will press it to push it completely out of the combination seat slot and into the sail seat slot, so that the sail seat 76 can rotate and drive the sail 77 to adjust the opening and closing angle.

[0054] The sail support 76 also has a spring fixing position 761 on its outer side, and a V-shaped spring 762 is installed inside the spring fixing position 761. One end of the V-shaped spring 762 has a protrusion, which abuts against the surface of one side of the assembly seat 7 to form a preload. After the V-shaped spring 762 inside the sail support 76 abuts against the assembly seat 7, the sail support 76 will spring up, achieving the purpose of unlocking. The sail support 76 can be rotated to various opening angles by moving it.

[0055] This invention provides a foldable pet stroller. When folded, the push rod retracts to shorten its length, and the locking mechanism releases the restriction on the relative position of the front leg and the push rod. Both the push rod and the first fixed seat move downward along the axial direction of the front leg, thereby causing the first fixed seat to drive the rear leg to rotate and fold towards the push rod and the front leg. At the same time, the distance between the first and second fixed seats increases, allowing the support member and the platform frame to rotate and extend towards the front leg, achieving the purpose of folding multiple parts close together. The basket can also be detached from the platform frame for better storage. People can also use the basket alone to carry small pets when going out, providing better functionality. Therefore, through the above structure, multiple parts can be unlocked and folded quickly and easily, making it more convenient for users to store or carry during use, while also providing different usage methods.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
