Description

Technical Field

[0001] This utility model relates to the field of pet stroller technology, and in particular to a folding pet stroller frame. Background Technology

[0002] A pet stroller is a handcart used to transport pets. Existing pet strollers consist of a frame and a pet basket. The pet basket is mounted on the frame and has a cavity for the pet to sit in. The frame includes a bracket and a push frame. The push frame is located at one axial end of the bracket and can be folded down onto the bracket or unfolded upwards relative to it. The bracket holds the pet basket. Because the bracket holds the pet basket, it is relatively long, resulting in a large packaging size and high transportation costs when the push frame is folded onto the bracket. Utility Model Content

[0003] The purpose of this invention is to provide a folding pet stroller frame to solve the problems of large packaging size and high transportation costs of existing pet stroller frames.

[0004] This utility model is achieved through the following technical solution:

[0005] A pet stroller folding frame includes a push frame, front legs, rear legs, a front bracket, a rear bracket, a linkage rod, and a connecting rod. The rear bracket is rotatably connected to the rear legs and the linkage rod, the front bracket is rotatably connected to the front legs and the rear bracket, the connecting rod is rotatably connected to the front legs and the rear legs, and the push frame is rotatably connected to the rear legs and the linkage rod. When the push frame rotates relative to the rear legs, it causes the front legs, the rear legs, the front bracket, and the rear bracket to fold closer together or unfold further apart.

[0006] Furthermore, the push frame has a connector that is rotatably connected to the rear leg and the linkage rod respectively. The connector has a receiving groove and a clearance hole. The receiving groove is for the rear leg to be inserted when the push frame is unfolded upwards. The clearance hole communicates with the receiving groove and is for the rear leg to pass through when the push frame is folded downwards.

[0007] Furthermore, the connector has a connecting arm that extends outward from the accommodating groove and is rotatably connected to the linkage rod.

[0008] Furthermore, the pusher also has an upper push rod and a lower push rod. The lower end of the lower push rod is provided with the connector head and the upper end is provided with the upper push rod. The upper push rod can be folded down on the lower push rod or unfolded up relative to the lower push rod.

[0009] Furthermore, the front bracket has two opposing front legs that are rotatably connected to the front support, and each front leg has a front wheel at its lower end. The rear bracket has two opposing rear legs that are rotatably connected to the rear support, and each rear leg has a rear wheel at its lower end. There are two connecting rods, which are opposing each other and rotatably connected to the front and rear legs respectively. There are two upper push rods and two lower push rods that correspond one-to-one. The two lower push rods are opposing each other and each has a connecting head at its lower end. There are two linkage rods, which are opposing each other and rotatably connected to the connecting head and the rear support respectively. The front and rear supports are arranged front and rear to form a ring frame.

[0010] Furthermore, a support rod is provided between the two rear leg rods.

[0011] Furthermore, the front wheel is detachably and fixedly connected to the front support rod, and the rear wheel is detachably and fixedly connected to the rear support rod.

[0012] Furthermore, a crossbar is detachably fixedly connected between the two upper push rods, and the crossbar is connected to the upper end of each of the two upper push rods.

[0013] Furthermore, the top of the connecting rod is provided with a socket, and an upper fastener is provided in the socket.

[0014] The advantages of this technical solution are that by configuring the pet stroller folding frame into a push frame, front legs, rear legs, front bracket, rear bracket, linkage rod, and connecting rod, when the push frame rotates relative to the rear legs, it causes the front legs, rear legs, front bracket, and rear bracket to fold closer to each other or unfold further apart. Since the front legs, rear legs, front bracket, and rear bracket fold together in the folded state, the pet stroller folding frame has a small packaging volume and low transportation cost. At the same time, since the front legs, rear legs, front bracket, and rear bracket unfold together to form a cavity for inserting the matching pet basket in the unfolded state, and the front bracket and rear bracket jointly support the pet basket, the pet stroller folding frame has good load-bearing capacity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-7 As shown, the pet stroller folding frame has a folded state and an unfolded state. It includes a push frame 1, a front leg 2, a rear leg 3, a front bracket 4, a rear bracket 5, a linkage rod 6, and a connecting rod 7. The rear bracket 5 is rotatably connected to the rear leg 3 and the linkage rod 6. The front bracket 4 is rotatably connected to the front leg 2 and the rear bracket 5. The connecting rod 7 is rotatably connected to the front leg 2 and the rear leg 3. The push frame 1 is rotatably connected to the rear leg 3 and the linkage rod 6. When the push frame 1 rotates relative to the rear leg 3, it causes the front leg 2, the rear leg 3, the front bracket 4, and the rear bracket 5 to fold closer to each other or unfold further apart.

[0026] When the push frame 1 is folded down onto the rear leg frame 3, it causes the front leg frame 2, rear leg frame 3, front bracket 4 and rear bracket 5 to fold inward simultaneously, so that the front leg frame 2, rear leg frame 3, front bracket 4 and rear bracket 5 fold closer to each other, thus switching the pet stroller folding frame to the folding state.

[0027] When the push frame 1 flips up and unfolds, it causes the front leg frame 2, rear leg frame 3, front bracket 4 and rear bracket 5 to flip outward simultaneously, so that the front leg frame 2, rear leg frame 3, front bracket 4 and rear bracket 5 unfold away from each other, and the pet stroller folding frame switches to the unfolded state.

[0028] In the unfolded state, the front leg 2, rear leg 3, front bracket 4, and rear bracket 5 together form an upward-opening cavity for inserting the matching pet basket (not shown in the figure), and the pet basket is supported by the front bracket 4 and the rear bracket 5.

[0029] In summary, this embodiment provides a folding pet stroller frame to solve the problems of large packaging size and high transportation costs of existing pet stroller frames. The folding frame is mainly configured as a push frame 1, front legs 2, rear legs 3, front support 4, rear support 5, linkage 6, and connecting rod 7. When the push frame 1 rotates relative to the rear legs 3, it causes the front legs 2, rear legs 3, front support 4, and rear support 5 to fold closer together or unfold further apart. Because the front legs 2, rear legs 3, front support 4, and rear support 5 fold together in the folded state, the packaging volume of the folding pet stroller frame is small and the transportation cost is low. Simultaneously, because the front legs 2, rear legs 3, front support 4, and rear support 5 unfold together in the unfolded state to form a cavity for inserting a matching pet basket, and the front support 4 and rear support 5 jointly support the pet basket, the folding pet stroller frame has good load-bearing capacity.

[0030] In this embodiment of the invention, the push frame 1 has a connector 101 that is rotatably connected to the rear leg 3 and the linkage rod 6 respectively. The connector 101 has a receiving groove 102 and a clearance hole 103. The receiving groove 102 is used to insert the rear leg 3 when the push frame 1 is unfolded, and the clearance hole 103 communicates with the receiving groove 102 and allows the rear leg 3 to pass through when the push frame 1 is folded down. By configuring the receiving groove 102 and the clearance hole 103 on the connector 101, the receiving groove 102 is used to insert the rear leg 3 when the push frame 1 is unfolded, and allows the rear leg 3 to pass through when the push frame 1 is folded down. Therefore, the front leg 2, rear leg 3, front bracket 4 and rear bracket 5 are tightly close together when folded together, and the front leg 2, rear leg 3, front bracket 4 and rear bracket 5 are compact and stable when unfolded together.

[0031] In this embodiment of the invention, the connector 101 has a connecting arm 104, which extends outward from the opening of the self-accommodating groove 102 and is rotatably connected to the linkage rod 6. This arrangement, by configuring the connecting arm 104 on the connector 101, which extends outward from the opening of the self-accommodating groove 102 and is rotatably connected to the linkage rod 6, ensures a tight connection and smooth rotation between the linkage rod 6 and the connector 101.

[0032] In this embodiment of the invention, the push frame 1 further includes an upper push rod 105 and a lower push rod 106. The lower end of the lower push rod 106 is provided with a connector 101, and the upper end is provided with the upper push rod 105. The upper push rod 105 can be folded down onto the lower push rod 106 or unfolded upwards relative to the lower push rod 106. By configuring the push frame 1 with an upper push rod 105 and a lower push rod 106, and the upper push rod 105 can be folded down onto the lower push rod 106 or unfolded upwards, the above configuration results in a small packaging volume and low transportation cost for the pet stroller folding frame in the folded state.

[0033] In this embodiment of the invention, the front frame 2 has two opposing front legs 201 that are rotatably connected to the front bracket 4. Each front leg 201 has a front wheel 8 at its lower end. The rear frame 3 has two opposing rear legs 301 that are rotatably connected to the rear bracket 5. Each rear leg 301 has a rear wheel 9 at its lower end. There are two connecting rods 7, which are opposing each other and rotatably connected to the front legs 201 and the rear legs 301 respectively. There are two upper push rods 105 and two lower push rods 106, which are one-to-one. The two lower push rods 106 are opposing each other and have connectors 101 at their lower ends respectively. There are two linkage rods 6, which are opposing each other and rotatably connected to the connectors 101 and the rear bracket 5 respectively. The front bracket 4 and the rear bracket 5 are semi-circular, and the front bracket 4 and the rear bracket 5 are arranged front and rear to form a ring frame. The above configuration gives the pet stroller folding frame good load-bearing capacity and stable and smooth folding / unfolding.

[0034] In this embodiment of the invention, a support rod 302 is provided between the two rear leg posts 301. This arrangement, by placing the support rod 302 between the two rear leg posts 301, gives the pet stroller folding frame good load-bearing capacity.

[0035] In this embodiment of the invention, the front wheel 8 is detachably and fixedly connected to the front leg rod 201, the rear wheel 9 is detachably and fixedly connected to the rear leg rod 301, and a crossbar 100 is detachably and fixedly connected between the two upper push rods 105, with the crossbar 100 connected to the upper ends of the two upper push rods 105 respectively. This arrangement, by configuring the crossbar 100 between the two upper push rods 105, gives the pet stroller folding frame good load-bearing capacity. Simultaneously, by configuring the front wheel 8 to be detachably and fixedly connected to the front leg rod 201, the rear wheel 9 to be detachably and fixedly connected to the rear leg rod 301, and the crossbar 100 to be detachably and fixedly connected to the two upper push rods 105, the pet stroller folding frame has a small packaging volume and low transportation cost when folded.

[0036] In this embodiment of the invention, the connecting rod 7 has a downward-opening relief groove (not shown in the figure). The upper ends of the front leg 2 and the rear leg 3 are inserted into the relief groove and are rotatably connected to the connecting rod 7 through the relief groove. The above arrangement ensures stable assembly of the front leg 2 and the rear leg 3 with the connecting rod 7 by configuring the relief groove on the connecting rod 7 for the insertion of the front leg 2 and the rear leg 3.

[0037] Furthermore, the top of the connecting rod 7 is provided with a socket 701, and an upper fastener (not shown in the figure) is provided inside the socket 701. The socket 701 is for inserting the plug on the matching pet basket, and the upper fastener is used to abut against the plug on the matching pet basket to prevent the plug from moving away from the socket 701.
