Description

Technical Field

[0001] The utility model relates to the technical field of children's products, in particular to a support foot with adjustable height and a baby walker with the support foot. Background Art

[0002] A baby walker is a means of transportation for babies before they can walk. A walker can moderately assist babies in learning to walk and is helpful in training the coordination of their limbs. Under the premise of ensuring safety and correct use, a walker provides a convenient tool for babies to learn to walk. However, due to the different heights of babies, a walker with adjustable height is needed. Currently, most of the adjustable height walkers on the market require you to press the buckle of the gear first and then pull the telescopic rod. That is, you need to press the gear and pull the telescopic rod upward at the same time to retract the gear into the telescopic rod. One hand is used to press the gear and the other hand to lift the telescopic rod. Sometimes you need to use your feet, but this process is not easy to operate and the telescopic rods on both sides need to be operated synchronously, which makes it more complicated to adjust the height of the walker. Utility Model Content

[0004] The technical solution to achieve the purpose of the utility model is: a height-adjustable support leg, characterized in that it includes a first support leg, a second support leg, and a height adjustment mechanism for adjusting the effective height between the first support leg and the second support leg, the second support leg is provided with a receiving cavity for accommodating the first support leg, the first support leg is inserted into the receiving cavity, the height adjustment mechanism includes a rack provided on the first support leg and arranged along the length direction of the first support leg, and an adjustment knob rotatably provided on the second support leg, the adjustment knob is provided with active teeth meshing with the rack.

[0005] Further optimization, the adjusting knob is radially provided with a positioning button, a button spring is provided between the positioning button and the adjusting knob, the positioning button includes a latching protrusion and a pressing portion extending outside the adjusting knob, the second leg is provided with a gear fixing seat, and the gear fixing seat is circumferentially provided with more than two slots for limiting the rotation of the adjusting knob and matching the latching protrusion.

[0006] Further optimized, the second support leg is detachably arranged in the accommodating cavity of the first support leg.

[0007] Further optimized, the first leg is provided with a long strip-shaped notch, and the rack is provided on an inner wall on one side of the notch.

[0008] Further optimization, the adjustment knob is provided with anti-slip grooves.

[0009] A baby walker comprises a top plate and a bottom plate, wherein the top plate and the bottom plate are connected via any one of the above-mentioned supporting legs.

[0010] The utility model has the following beneficial effects: it is easy to use and convenient to operate. The thumb of one hand presses the pressing part, and the other finger cooperates with the thumb to rotate the adjustment knob, driving the active gear to rotate. Both hands can rotate the adjustment knob synchronously, thereby adjusting the height of the support leg. The first support leg is limited to move relative to the second support leg through the cooperation of the clamping protrusion and the clamping groove, that is, the setting and debugging locking is realized, and the first support leg and the second support leg can be disassembled and assembled at the same time.

[0017] like Figure 1 to Figure 5 As shown, a baby walker comprises a top plate 1 and a bottom plate 2, wherein the top plate 1 is connected to the bottom plate 2 via legs 3, the legs 3 comprising a first leg 3.1, a second leg 3.2, and a height adjustment mechanism 4 for adjusting the effective debugging between the first leg 3.1 and the second leg 3.2, the second leg 3.2 being provided with a receiving cavity 3.3 for receiving the first leg 3.1, the first leg 3.1 being detachably inserted into the receiving cavity 3.3, the first leg 3.1 being provided with a long strip-shaped notch 3.4, the height adjustment mechanism 4 comprising a rack 4.1 provided on the first leg 3.1 and arranged along the length direction of the first leg 3.1, and an adjusting knob 4.2 rotatably provided on the second leg 3.2, the adjusting knob 4.2 being provided with an active tooth 4.3 meshing with the rack 4.1; the rack 4.1 being provided on an inner wall on one side of the notch 3.4. One end of the first leg 3.1 away from the second leg 3.2 is connected to the top plate 1, and one end of the second leg 3.2 away from the first leg 3.1 is connected to the bottom plate 2.

[0018] The adjusting knob 4.2 is provided with a positioning button 5 radially, and a button spring 6 is provided between the positioning button 5 and the adjusting knob 4.2. The positioning button 5 includes a pressing portion 5.1 extending outside the adjusting knob and a clamping protrusion 5.2 fixedly connected to the pressing portion 5.1 and shorter than the pressing portion 5.1. The second leg 3.2 is provided with a gear fixing seat 3.5 matching the adjusting knob 4.2. The gear fixing seat 3.5 is provided with more than two clamping grooves 3.6 for limiting the rotation of the adjusting knob 4.2 and matching the clamping protrusion 5.2. In this embodiment, there are 5 clamping grooves 3.6, which are evenly distributed on the gear fixing seat 3.5 in the circumferential direction.
