Description

Technical Field

[0001] This utility model relates to the field of baby strollers, and more particularly to a front wheel orientation and fixing mechanism for a baby stroller. Background Technology

[0002] Strollers are a common mode of transportation for infants when going out. Most current strollers feature front wheels designed with a 306-degree free-rotation structure, allowing for flexible adjustment of the stroller's forward movement via the front wheels. In certain situations, such as pushing the stroller down a smooth downhill slope, it's necessary to restrict the front wheels, ideally locking them to only roll forward. This requires a front wheel steering mechanism. Currently, most front wheel steering mechanisms are button-type. While they do provide steering and locking, the indicator is not clear enough to visually determine whether steering is engaged. Therefore, we have designed a new front wheel steering and locking mechanism for strollers. Utility Model Content

[0003] To solve the technical problem of rapid front wheel orientation, this utility model provides a front wheel orientation and fixing mechanism for a baby stroller.

[0004] This utility model is achieved by the following technical solution: a front wheel orientation and fixing mechanism for a baby stroller, including a connecting frame, a front wheel component rotatably mounted below the connecting frame, a mounting frame mounted above the connecting frame, and a connecting shaft mounted at the center of the top of the mounting frame;

[0005] A front wheel inner plug is rotatably mounted on the top of the mounting bracket. A directional component is slidably arranged on the left side of the front wheel inner plug, and a front wheel fixing plate is slidably arranged inside it. The front wheel inner plug passes through the top and bottom to form a front wheel mounting hole. The connecting shaft is rotatably placed in the front wheel mounting hole. The directional component is inserted into the mounting bracket, and the front wheel fixing plate is rotatably connected to the connecting shaft.

[0006] A front wheel connector is screwed on the upper part of the front wheel inner plug. A directional button is rotatably pressed between the front wheel connector and the front wheel inner plug. The inner ring of the directional button is provided with a groove with a convex structure. It is sleeved on the front wheel inner plug through the groove. The upper surface of the directional button is in sliding contact with the directional component.

[0007] As a further improvement to the above solution, a directional groove is provided on the front side of the outer surface of the inner plug of the front wheel. A directional component is slidably arranged in the directional groove. A return spring is provided at the upper end of the directional component, and the upper end of the return spring abuts against the top of the inner part of the front wheel joint. The return spring causes the directional component to have a downward tendency, thereby enabling the directional component to move downward and connect with the mounting bracket, thereby fixing and oriented it so that it will not deflect.

[0008] The bottom end of the directional groove passes through the upper and lower sides of the front wheel inner plug, and a directional hole is provided above the mounting bracket. The lower end of the directional component is inserted into the directional hole, so that the front wheel inner plug and the mounting bracket are integrated, thereby preventing it from rotating and thus oriented.

[0009] As a further improvement to the above solution, an unlocking block is provided on the upper left side of the directional button. A locking groove is provided on the upper part of the unlocking block, and an arc-shaped surface is provided between the left and right sides of the locking groove and the upper part of the unlocking block. A slope is provided on one side surface of the unlocking block. Both the slope and the arc-shaped surface have a certain inclination angle, which allows the sliding slope of the directional component to slide along the slope and the arc-shaped surface, thereby facilitating the orientation or deflection of the mounting bracket and the front wheel component.

[0010] The outer surface of the directional component protrudes outward to form a protrusion, and the bottom end of the protrusion is provided with a sliding slope. The sliding slope allows it to move along the slope or arc surface, thereby enabling the directional component to slide up and down along the directional groove.

[0011] As a further improvement to the above solution, a protruding ring is provided at the bottom outer end of the front wheel inner plug, and a limiting block is provided above the protruding ring. A limiting arc is provided through the upper and lower right side of the inner ring of the directional button. The limiting block is placed in the limiting arc, which can limit the deflection angle of the directional button, thereby facilitating the up and down sliding of the directional component.

[0012] The outer right side of the directional button is integrally provided with a lever to facilitate rotation of the directional button.

[0013] As a further improvement to the above solution, a disassembly and installation port is formed through the upper left and right sides of the inner plug of the front wheel. The disassembly and installation port is connected to the front wheel mounting hole. The front wheel fixing plate is slidably inserted into the disassembly and installation port. An installation port is opened on the front wheel fixing plate. The connecting shaft passes through the disassembly and installation port and is placed above it.

[0014] A groove is provided on the right side of the disassembly and installation port, wherein the groove is not connected to the front wheel mounting hole. A front wheel disassembly spring is provided in the groove, and the other end of the front wheel disassembly spring abuts against the disassembly and installation port. A notch is also provided on the front wheel connector, and the front wheel fixing plate is placed on the outside through the notch. The front wheel disassembly spring causes the front wheel fixing plate to have a tendency to move outward, thereby fixing the front wheel to the connection with the connecting shaft.

[0015] As a further improvement to the above solution, a connecting ring groove is provided above the outer ring of the connecting shaft. The protruding part on the left end of the disassembly and installation port of the front wheel fixing plate forms an installation protrusion. The installation protrusion is engaged in the connecting ring groove. After the connecting shaft passes through the disassembly and installation port, the front wheel fixing plate will move outward under the action of the front wheel disassembly spring, thereby causing the installation protrusion to be engaged in the connecting ring groove, so that the connecting shaft cannot move downward and disengage.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model has a directional component that slides up and down on the left side of the outer side of the front wheel inner plug. With the directional button, the directional component can be inserted into or disconnected from the front wheel assembly, which facilitates the quick orientation or rotation of the front wheel assembly. The directional button requires a certain angle of deflection to use, and the orientation of the front wheel assembly can be quickly determined by whether it is deflected, which improves convenience.

[0018] 2. By sliding the front wheel fixing plate left and right inside the front wheel inner plug, and with the installation protrusion and the front wheel removal spring, the connecting shaft in the front wheel assembly can be quickly installed in the front wheel inner plug and is also easy to remove. The front wheel fixing plate and the connecting shaft are rotatably connected without interfering with the rotation of the front wheel assembly. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-Figure 5 The front wheel orientation and fixing mechanism of a baby stroller according to this embodiment includes a connecting frame 2, a front wheel component 1 rotatably mounted below the connecting frame 2, a mounting frame 3 mounted above the connecting frame 2, and a connecting shaft 31 mounted at the center of the top of the mounting frame 3;

[0029] The front wheel inner plug 7 is rotatably mounted on the top of the mounting bracket 3. The front wheel inner plug 7 has a directional component 8 that slides up and down on the left side, and a front wheel fixing piece 6 that slides left and right inside it. The front wheel inner plug 7 passes through to form a front wheel mounting hole 72. The connecting shaft 31 is rotatably placed in the front wheel mounting hole 72. The directional component 8 is inserted into the mounting bracket 3, and the front wheel fixing piece 6 is rotatably connected to the connecting shaft 31.

[0030] A front wheel connector 4 is screwed on the upper part of the front wheel inner plug 7. A directional button 5 is rotated and pressed between the front wheel connector 4 and the front wheel inner plug 7. The inner ring of the directional button 5 is provided with a groove with a convex structure. It is sleeved on the front wheel inner plug 7 through the groove. The upper surface of the directional button 5 is in sliding contact with the directional part 8.

[0031] The front wheel inner plug 7 has a directional groove 71 on the front side of its outer surface. A directional member 8 is slidably arranged in the directional groove 71. A return spring 81 is provided at the upper end of the directional member 8. The upper end of the return spring 81 abuts against the top of the front wheel joint 4. The return spring 81 causes the directional member 8 to have a downward tendency, which in turn allows the directional member 8 to move downward and connect with the mounting bracket 3, thereby fixing and oriented it so that it will not deflect.

[0032] The bottom end of the directional groove 71 passes through the upper and lower sides of the front wheel inner plug 7, and a directional hole is provided above the mounting bracket 3. The lower end of the directional component 8 is inserted into the directional hole, so that the front wheel inner plug 7 and the mounting bracket 3 are connected as one unit, thereby preventing it from rotating and thus directionalizing it.

[0033] An unlocking block 52 is provided on the upper left side of the directional button 5. A locking groove 53 is provided on the upper part of the unlocking block 52. An arc-shaped surface is provided between the left and right sides of the locking groove 53 and the upper part of the unlocking block 52. An inclined surface is provided on one side of the unlocking block 52. Both the inclined surface and the arc-shaped surface have a certain tilt angle, which allows the sliding inclined surface 82 of the directional component 8 to slide along the inclined surface and the arc-shaped surface, thereby facilitating the orientation or deflection of the mounting bracket 3 and the front wheel component 1.

[0034] The outer surface of the directional member 8 protrudes outward to form a protrusion, and the bottom end of the protrusion is provided with a sliding inclined surface 82. The sliding inclined surface 82 allows it to move along the inclined surface or the arc surface, thereby allowing the directional member 8 to slide up and down along the directional groove 71.

[0035] The bottom of the front wheel inner plug 7 is provided with a protruding ring, and a limit block is provided above the protruding ring. The right side of the inner ring of the directional button 5 is provided with a limit arc 54 running vertically through it. The limit block is placed inside the limit arc 54, which can limit the deflection angle of the directional button 5, thereby facilitating the vertical sliding of the directional part 8.

[0036] A lever 51 is integrated on the right side of the outer surface of the directional button 5 to facilitate rotation of the directional button 5.

[0037] A disassembly and installation port 73 is formed by passing through the upper left and right sides of the inner plug 7 of the front wheel. The disassembly and installation port 73 is connected to the front wheel mounting hole 72. The front wheel fixing plate 6 is slidably inserted into the disassembly and installation port 73. The front wheel fixing plate 6 has an installation port 62. The connecting shaft 31 passes through the disassembly and installation port 73 and is placed above it.

[0038] A groove is provided on the right side of the disassembly and installation port 73. The groove is not connected to the front wheel mounting hole 72. A front wheel disassembly spring 61 is provided in the groove. The other end of the front wheel disassembly spring 61 abuts against the disassembly and installation port 73. A notch is also provided on the front wheel connector 4. The front wheel fixing plate 6 is placed on the outside through the notch. The front wheel disassembly spring 61 makes the front wheel fixing plate 6 tend to move outward, thereby fixing the front wheel to the connection with the connecting shaft 31.

[0039] A connecting ring groove 32 is provided above the outer ring of the connecting shaft 31. The left end of the disassembly and installation port 73 of the front wheel fixing plate 6 has a protruding part forming an installation protrusion 63. The installation protrusion 63 is engaged in the connecting ring groove 32. After the connecting shaft 31 passes through the disassembly and installation port 73, the front wheel fixing plate 6 will move outward under the action of the front wheel disassembly spring 61, thereby causing the installation protrusion 63 to be engaged in the connecting ring groove 32, so that the connecting shaft 31 cannot move downward and disengage.

[0040] The implementation principle of the front wheel orientation and fixing mechanism of a baby stroller in this embodiment is as follows: the front wheel component 1, the connecting frame 2, the mounting frame 3, and the connecting shaft 31 are connected together to form a front wheel assembly. During installation, the front wheel fixing plate 6 is first pressed inward. At this time, the mounting protrusion 63 in the front wheel fixing plate 6 will move to the left a certain distance. Then, the connecting shaft 31 in the front wheel assembly can be inserted from bottom to top into the front wheel mounting hole 72 of the front wheel inner plug 7. After the insertion is completed, the front wheel fixing plate 6 is released. Under the action of the front wheel disassembly spring 61, the front wheel fixing plate 6 will move outward, thereby causing the mounting protrusion 63 to be engaged in the connecting ring groove 32, so that the connecting shaft 31 cannot move downward and disengage.

[0041] When disassembling, press the front wheel retaining plate 6 inward to disengage the mounting protrusion 63 from the connecting ring groove 32, and then pull the front wheel assembly out downward for disassembly.

[0042] When the front wheel assembly needs to be oriented, the oriented button 5 is rotated clockwise using the paddle 51. At this time, the unlocking block on the oriented button 5 will also rotate clockwise, allowing the sliding ramp 82 of the oriented component 8 to slide along the arc groove and disengage from the unlocking block 52. At this time, the oriented component 8 has a downward tendency under the action of the return spring 81. Then, when the front wheel assembly is rotated and the oriented hole on the front wheel assembly is aligned with the oriented component 8, the oriented component 8 is inserted into the oriented hole under the action of the return spring 81, and at this time, it can be oriented and locked.

[0043] When it is necessary to deflect the front wheel assembly, turn the directional button 5 counterclockwise, and the directional part 8 will move upward and disengage from the front wheel assembly. The directional part 8 will then be placed in the locking groove 53 of the unlocking block 52, at which point the front wheel assembly can rotate in any direction.

[0044] By sliding the directional component 8 up and down on the left side of the front wheel inner plug 7, and cooperating with the directional button 5, the directional component 8 can be inserted into or disconnected from the front wheel assembly, which facilitates the quick orientation or rotation of the front wheel assembly. In addition, the directional button 5 requires a certain angle of deflection to use, and whether the front wheel assembly is oriented can be quickly determined by whether it is deflected, which improves convenience.

[0045] By sliding the front wheel fixing plate 6 left and right inside the front wheel inner plug 7, and cooperating with the mounting protrusion 63 and the front wheel removal spring 61, the connecting shaft 31 in the front wheel assembly can be quickly installed in the front wheel inner plug 7 and is also easy to disassemble. Furthermore, the front wheel fixing plate 6 and the connecting shaft 31 are rotatably connected without interfering with the rotation of the front wheel assembly.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
