Description

Technical Field

[0001] This utility model belongs to the field of children's vehicle manufacturing technology, specifically relating to an anti-slip baby stroller. Background Technology

[0002] A stroller is a utility vehicle designed to facilitate outdoor activities for infants. To ensure safety during stroller use, a brake is usually installed on the side of the stroller to mitigate emergency situations. The stroller's braking system is directly related to the child's safety.

[0003] In existing technology, stroller brakes need to be manually activated or deactivated by parents. When the stroller is on a slope, there may be situations where parents fail to activate the stroller brakes due to negligence. As a result, the stroller will slide down the slope due to its own weight, posing a safety hazard to children riding in the stroller. Utility Model Content

[0004] This utility model provides an anti-slip stroller, which aims to improve the braking effect of the stroller on slopes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A slope-resistant stroller is provided, including a frame, wheels, and a push handle. A sliding rod is slidably mounted inside the frame, and an elastic pushing member is provided on the sliding rod. The elastic pushing member is connected to the interior of the frame and applies a downward elastic pushing force to the sliding rod so that its lower end extends out of the frame. The wheels are located at the bottom of the frame and have limiting holes that engage with the end of the sliding rod extending out of the frame. The push handle is rotatably connected to the top of the frame and has a pull rod inside. The pull rod is connected to the sliding rod, and the push handle has a braking state where it swings to a first angle under the elastic traction transmitted from the sliding rod to the pull rod, and a pushing state where it swings to a second angle under force to disengage the sliding rod from the limiting hole via the pull rod.

[0006] In one possible implementation, the frame is provided with multiple limiting plates, each with a limiting hole suitable for the slide bar to pass through, and the elastic pusher is connected to the limiting plate.

[0007] In one possible implementation, a mounting plate is provided on the slide bar, the mounting plate slides against the inner wall of the frame, and an elastic pusher is provided on the mounting plate.

[0008] In one possible implementation, the slide bar and the pull bar are connected by a first connecting rod located inside the frame, with both ends hinged to the slide bar and the pull bar, respectively.

[0009] In one possible implementation, the top of the wheels is equipped with a baffle, which is connected to the frame.

[0010] In one possible implementation, the baffle has a through hole suitable for the slide rod to pass through.

[0011] In one possible implementation, the traveling wheels include two front rollers and two rear rollers, both of which are rotatably connected to the frame, and each of the two rear rollers is provided with a limit insertion hole.

[0012] In one possible implementation, each of the two rear rollers is provided with a limiting member, which has multiple limiting holes along its circumference, and the slide rod is aligned with the limiting member along the radial direction of the rear roller.

[0013] In one possible implementation, two sliding rods are provided inside the frame and are respectively engaged with two limiting members; the two rods are connected by a second connecting rod.

[0014] In one possible implementation, a support frame is hinged to the frame to support the crib.

[0015] The beneficial effects of the anti-slip stroller provided by this utility model are as follows: Compared with the prior art, this utility model uses wheels to drive the frame to move on the road; the wheels are provided with limiting holes, and a sliding rod is slidably provided inside the frame. The sliding rod is connected to the frame through an elastic pusher. The elastic pusher can push the sliding rod with elastic force, causing the sliding rod to slide downward and engage with the limiting holes, thereby braking the frame and preventing the wheels from driving the frame to move; when the frame needs to move, the push handle is swung to the second angle by swinging the push handle. The lever is pulled upwards by the pull rod, causing the slide rod to separate from the limiting socket. The push handle is then pushed by external force, and the wheels can drive the frame to move. When the frame is on a slope, the external force of the push handle disappears, and the slide rod slides downwards under the action of the elastic pusher to insert into the limiting socket. The push handle swings to the first angle under the elastic traction transmitted from the slide rod to the pull rod, and the push handle switches to the braking state, so that the frame is braked on the slope, preventing the frame from slipping on the slope due to its own weight, thus improving safety.

[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Please refer to the following: Figures 1 to 3 The anti-slip stroller provided by this utility model will now be described. The anti-slip stroller includes a frame 10, wheels 20, and a push handle 30. A sliding rod 11 is slidably mounted inside the frame 10, and an elastic pusher 12 is mounted on the sliding rod 11. The elastic pusher 12 is connected to the inside of the frame 10 and applies a downward elastic pusher force to the sliding rod 11 so that its lower end extends out of the frame 10. The wheels 20 are located at the bottom of the frame 10 and have a limiting insertion hole 241. The limiting insertion hole 241 engages with the end of the sliding rod 11 extending out of the frame 10. The push handle 30 is rotatably connected to the top of the frame 10. A pull rod 31 is mounted inside the push handle 30 and is connected to the sliding rod 11. The push handle 30 has a braking state where it swings to a first angle under the elastic traction transmitted from the sliding rod 11 to the pull rod 31, and also has a pushing state where it swings to a second angle under force to push the sliding rod 11 out of the limiting insertion hole 241 via the pull rod 31.

[0029] It should be noted that the frame 10 is equipped with a traveling wheel 20 at the bottom, which drives the frame 10 to move on the ground. When the frame 10 moves on the ground, the operating push handle 30 swings to the second angle and pulls the slide rod 11 upward inside the frame 10 through the pull rod 31, keeping the slide rod 11 separated from the limiting insertion hole 241, so that the frame 10 can move on the ground. The elastic push member 12 can be a spring. When the external force of the operating push handle 30 disappears, the elastic push member 12 pushes the slide rod 11 downward through the elastic force, so that the slide rod 11 is inserted into the limiting insertion hole 241. The push handle 30 swings to the first angle under the elastic traction transmitted from the slide rod 11 to the pull rod 31 and switches to the braking state, which can restrict the movement of the frame 10 on the ground.

[0030] The beneficial effects of the anti-slip stroller provided by this utility model are as follows: Compared with the prior art, this utility model uses the walking wheels 20 to drive the frame 10 to walk on the road surface; the walking wheels 20 are provided with a limiting insertion hole 241, and a sliding rod 11 is slidably provided inside the frame 10, and the sliding rod 11 is connected to the frame 10 through an elastic pushing member 12. The elastic pushing member 12 can push the sliding rod 11 with elastic force, so that the sliding rod 11 slides downward and engages with the limiting insertion hole 241, thereby braking the frame 10 and preventing the walking wheels 20 from driving the frame 10 to move; when the frame 10 needs to move, the push handle 30 is swung to the second position by swinging the push handle 30. The angle is adjusted and the sliding rod 11 is pulled upward by the pull rod 31, so that the sliding rod 11 is separated from the limiting insertion hole 241. The push handle 30 is in the pushing state under the external force, and the walking wheel 20 can drive the frame 10 to move. When the frame 10 is on the slope, the external force of operating the push handle 30 disappears, and the sliding rod 11 slides downward under the action of the elastic push member 12 to insert into the limiting insertion hole 241. The push handle 30 swings to the first angle under the elastic traction transmitted from the sliding rod 11 to the pull rod 31. The push handle 30 switches to the braking state, so that the frame 10 is braked on the slope, so as to avoid the frame 10 from slipping on the slope due to its own weight, thereby improving safety.

[0031] In one possible implementation, please refer to Figure 4 and Figure 5 The frame 10 has multiple limiting plates 13 inside, and each limiting plate 13 has a limiting hole suitable for the slide rod 11 to pass through. The elastic pusher 12 is connected to the limiting plate 13.

[0032] It should be noted that the frame 10 has multiple limiting plates 13 inside, and each limiting plate 13 has a limiting hole; the slide rod 11 slides against the inner wall of each limiting hole, and each limiting hole cooperates to limit the position of the slide rod 11 in the frame 10, so that the slide rod 11 can always slide vertically inside the frame 10, which can prevent the slide rod 11 from deviating inside the frame 10, and allow the slide rod 11 to slide down vertically and insert into the limiting hole 241 to stop the frame 10.

[0033] In one possible implementation, please refer to Figure 6 and Figure 7 The slide bar 11 is provided with a mounting plate 111, which slides against the inner wall of the frame 10. The elastic pusher 12 is provided on the mounting plate 111.

[0034] It should be noted that the slide bar 11 is provided with a mounting plate 111, which is circumferentially mounted on the side wall of the slide bar 11 and slides against the inner wall of the frame 10. The mounting plate 111 can be located below each limiting plate 13. The mounting plate 111 can prevent the slide bar 11 from sliding upward and disengaging from the limiting plate 13. After sliding upward to a certain distance, the mounting plate 111 is limited by the lowest limiting plate 13, preventing the slide bar 11 from sliding further upward. The mounting plate 111 is provided with an elastic pusher 12, which can push the mounting plate 111 downward through elastic force when the external force of the operating push handle 30 disappears, so that the slide bar 11 can be inserted and engaged with the limiting insertion hole 241. When the push handle 30 is swung and swung to the second angle, the mounting plate 111 slides upward with the slide bar 11 and compresses the elastic pusher 12. Mounting plate 111 can also be located above each limiting plate 13, so that elastic push member 12 is located above the limiting plate 13. When push handle 30 swings to the first angle, slide rod 11 is engaged with limiting insertion hole 241. When push handle 30 swings to the second angle, pull rod 31 pulls slide rod 11 upward and pulls elastic push member 12 to extend, so that elastic push member 12 has elastic force to reset slide rod 11 and engage with limiting insertion hole 241. When the external force of operating push handle 30 disappears, slide rod 11 can automatically slide down and engage with limiting insertion hole 241, so that frame 10 is braked on the ground.

[0035] In one possible implementation, please refer to Figure 4 and Figure 5 The slide rod 11 and the pull rod 31 are connected by a first connecting rod 14, which is located inside the frame 10 and is hinged at both ends to the slide rod 11 and the pull rod 31 respectively.

[0036] It should be noted that the pull rod 31 is located above the slide rod 11 and is offset from the slide rod 11 in the vertical direction. The pull rod 31 and the push handle 30 are hinged through the first connecting rod 14. When an external force is applied to make the push handle 30 swing to the second angle, the pull rod 31 drives the first connecting rod 14 to move upward and pulls the slide rod 11 to slide upward, so that the slide rod 11 separates from the limiting insertion hole 241, allowing the frame 10 to move on the ground. When the external force applied to the push handle 30 disappears, the elastic force of the elastic push member 12 pulls the slide rod 11 to slide downward. The slide rod 11 pulls the first connecting member and pulls the pull rod 31 to swing, so that the push handle 30 swings to the first angle. At this time, the slide rod 11 slides downward inside the frame 10 and engages with the limiting insertion hole 241, so that the frame 10 can be braked on the ground.

[0037] In one possible implementation, please refer to Figure 2 and Figure 3 The top of the walking wheel 20 is provided with a baffle 21, and the baffle 21 is connected to the frame 10.

[0038] It should be noted that the baffle 21 can be a rubber mudguard, which can block mud and sand from splashing onto the road surface when the frame 10 is in motion, thus ensuring the cleanliness of the frame 10.

[0039] In one possible implementation, please refer to Figure 8 The baffle 21 is provided with a through hole 211 suitable for the slide rod 11 to pass through.

[0040] It should be noted that the top of the baffle 21 is provided with a through hole 211, and the through hole 211 is located above the limiting insertion hole 241. The slide rod 11 can slide down along the frame 10 under the pushing action of the elastic pushing member 12 and pass through the through hole 211 to engage with the limiting insertion hole 241, so that the frame 10 can be braked on the ground. Even when the frame 10 is on a slope, it can still brake, improving the safety of use.

[0041] In one possible implementation, please refer to Figure 2 and Figure 3 The traveling wheel 20 includes two front rollers 22 and two rear rollers 23. Both the front rollers 22 and the rear rollers 23 are rotatably connected to the frame 10, and each of the two rear rollers 23 is provided with a limiting insertion hole 241.

[0042] It should be noted that the front roller 22 is located at the front of the frame 10, and the rear roller 23 is located at the rear of the frame 10. External force is applied to the push handle 30 and acts on the rear of the frame 10. When the frame 10 swings to the second angle of the push handle 30 during movement, the center of gravity of the frame 10 shifts rearward, making operation more flexible and preventing the frame 10 from tilting forward during movement, thus improving safety. The rear roller 23 has a limiting hole 241. When the slide rod 11 slides downward under the pushing force of the elastic pusher 12, the rear roller 23 is braked, causing the frame 10 to brake and come to a stop. The frame 10 remains stationary on slopes, preventing it from slipping due to its own weight and further improving safety.

[0043] In one possible implementation, please refer to Figures 6 to 8 Each of the two rear rollers 23 is provided with a limiting member 24. The limiting member 24 is provided with multiple limiting holes 241 along its circumference. The slide rod 11 is aligned with the limiting member 24 along the radial direction of the rear roller 23.

[0044] It should be noted that the limiting member 24 is fixedly connected to the rear roller 23. When the slide rod 11 is inserted into the limiting socket 241, the rear roller 23 stops rolling, causing the frame 10 to brake to the ground and achieve the braking of the frame 10. The limiting member 24 is provided with multiple limiting sockets 241 at intervals along its circumference, and each limiting socket 241 can be inserted and cooperate with the slide rod 11. The limiting member 24 and the slide rod 11 are radially aligned, which can ensure that the slide rod 11 can effectively insert and cooperate with the limiting socket 241 when it slides downward under the pushing force of the elastic pushing member 12, avoiding radial offset between the two and causing misalignment, which would affect the braking of the frame 10. When the frame 10 is on a slope, the external force of the operating handle 30 disappears, and the frame 10 moves down the slope under its own weight. The rear roller 23 rolls along the slope, and the slide bar 11 slides down under the pushing force of the elastic pusher 12 and inserts into the nearest limiting socket 241, thus braking the frame 10 on the slope. Providing multiple limiting sockets 241 reduces the sliding distance of the frame 10 on the slope when the external force of the operating handle 30 disappears, enabling rapid braking of the frame 10 and improving safety.

[0045] In one possible implementation, please refer to Figure 9 The frame 10 has two sliding rods 11 inside, which are respectively engaged with two limiting members 24; the two pull rods 31 are connected by the second connecting rod 32.

[0046] It should be noted that the two pull rods 31 are connected by the second connecting rod 32, so that the two pull rods 31 form a whole and pull the slide rod 11 above the two rear rollers 23 together to achieve synchronous braking of the two rear rollers 23. This prevents one of the rear rollers 23 from not braking when the frame 10 stops on the ground, thereby improving safety and reducing risk.

[0047] In one possible implementation, please refer to Figure 1 A support frame 40 is hinged to the frame 10, and the support frame 40 is used to support the crib.

[0048] It should be noted that two support frames 40 are hinged to the frame 10. When the stroller is in use, the two support frames 40 rotate around the hinge point and move away from each other, forming a space for holding the crib between the two support frames 40. When the stroller is stored, the crib is separated from the frame 10, and the two support frames 40 are rotated to bring them closer together, reducing the storage space.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
