Description

baby stroller with reversible push handle

technical field

The utility model relates to a baby stroller with a reversible push handle.

Background technique

In the prior art, in order to realize the reversing of the push handle of the baby stroller, generally the front and rear ends of the side armrests are provided with raised blocks, and the push handle is provided with a slot matching the blocks. The locking of the push handle at different working positions can be realized by snapping the above-mentioned block into the slot, the structure is simple, and the direction of rotation is convenient. Its disadvantage is that since the front and rear ends of the side armrests are provided with protruding blocks, only one block can be matched with the slot on the push handle during work, so there will always be a block exposed to the outside. A raised part is formed, which affects the overall appearance, and easily causes children to be bumped and injured, thus posing a potential safety hazard.

Contents of the invention

The purpose of the utility model is to provide a baby stroller with reversible push handle, which is more beautiful and safer as a whole.

In order to achieve the above object, the technical solution adopted in the utility model is:

The sleeve is arranged between the rotating shaft and the side armrest.

A compression spring is arranged between the rotating shaft and the sleeve on the push handle.

The push handle is provided with an operating mechanism for converting the protrusion from the first working state to the third working state or converting the protrusion from the second working state to the third working state.

The operating mechanism includes a traction cable arranged on the push handle, the traction cable has a fixed end connected to the sleeve, the free end of the traction cable extends downward from the fixed end along the push handle, And walk around a reversing mechanism that makes the pulling rope change direction and then extend upwards.

The push handle is provided with a traction cable, the traction cable has a fixed end connected to the sleeve, the free end of the traction cable extends downward from the fixed end along the push handle, and bypasses a The reversing mechanism of cable reversing extends upwards again.

A ring is arranged on the sleeve, and the fixed end of the pulling rope is fixedly connected with the ring.

The reversing mechanism is a cylindrical protrusion arranged on the push handle, and the traction cable goes around the protrusion.

Due to the adoption of the above technical scheme, the utility model has the following advantages: because a sleeve is slidingly sleeved on the push handle, the sleeve has a protrusion, and the front end and the rear end of the side armrest are provided with The protrusion is matched with the card slot, and the above-mentioned protrusions are all stuck in the card slot in the forward and backward states of the push handle, and no protruding part will be formed on the vehicle body, so the whole is more beautiful and avoids the Children are bumped by bumps, which eliminates potential safety hazards.

Detailed ways

As shown in accompanying drawing 1, a kind of baby stroller with reversible push handle comprises a vehicle frame 1, a front wheel 13 arranged at the front of the vehicle frame 1, a rear wheel 14 arranged at the rear of the vehicle frame 1, The side armrests 2 arranged on both sides of the vehicle frame 1, the push handle 3 pivotally connected to the vehicle frame 1 through the rotating shaft 12, the sleeve 4 is slidably sleeved on the push handle 3, the front end and the rear end of the side armrest 2 Each is provided with a front card slot 7 and a rear card slot 6, and the sleeve 4 has a protrusion 5 matched with the front card slot 7 and the rear card slot 6, and the protrusion 5 is compatible with the front card slot 7 and the rear card slot 6. The cooperation has at least three working states: in the first working state, the protrusion 5 is locked in the rear card slot 6, and the push handle 3 is locked in the backward state; in the second working state, the protrusion 5 is locked Clamped in the front card slot 7, the push handle 3 is locked in the forward state; in the third working state, the protrusion 5 is separated from the front card slot 7 and the rear card slot 6, and the push handle 3 can be Rotate relative to the shaft 12.

The sleeve 4 in this embodiment is arranged between the rotating shaft 12 and the side armrest 2, and the push handle 3 is provided with a compression spring 8 between the rotating shaft 12 and the sleeve 4, and one end of the compression spring 8 is against the rotating shaft 12, The other end is against the sleeve 4. The restoring force of the compression spring 8 makes the sleeve 4 have a tendency to slide upward along the push handle 3, so that the protrusion 5 is stably in the first working state or the second working state.

As shown in Figure 5, in order to facilitate the operation, in this embodiment, the push handle 3 is provided with a function for converting the protrusion 5 from the first working state to the third working state or converting the protrusion 5 from the second working state to the second working state. The operating mechanism of the three working states, the operating mechanism is the traction cable 11 arranged on the push handle 3, the traction cable 11 has a fixed end 111 connected with the sleeve 4, and its free end 112 is along the push handle 3 from the fixed end 111. Extend downwards, and extend upwards again after walking around a reversing mechanism that makes the pulling rope 11 change direction. In this embodiment, the sleeve 4 is provided with a ring 9, and the fixed end 111 of the traction cable 11 is fixedly connected with the ring 9. The above-mentioned reversing mechanism is a cylindrical protrusion 10 arranged on the push handle 6, and the traction cable 11 The protrusion 10 is bypassed (in order to make the key structure more clear, the content of this part is not reflected in the previous drawings). When the push handle 3 changes direction, it is only necessary to pull the free end 112 of the traction cable 11, and the traction cable 11 can pull the sleeve 4 to slide down along the push handle 3 through the fixed end 111, so that the protrusion 5 can be disengaged from the slot , the push handle 3 can be rotated around the rotating shaft 12 for reversing operation. The traction cable 11 can also be fixed with the sleeve 4 in other ways, such as a column is arranged on the sleeve 4, and the fixed end 111 of the traction cable 11 is fixedly connected to the column, and the reversing mechanism can also be in other forms.

In the utility model, the protrusion 5 is arranged on the sleeve 4, and the sleeve 4 can slide along the push handle 3, and the front and rear ends of the side armrest 2 are provided with a front draw-in groove 7 and a rear draw-in groove 6. Therefore, when the push handle 3 is forward, the protrusions 5 are all stuck in the front card slot 7; when the push handle 3 is backward, the protrusions 5 are all stuck in the rear card slot 6. The protruding part is formed on the vehicle body, which makes the whole body more beautiful, and prevents children from being bumped by the protrusion 5, thereby eliminating potential safety hazards.
