Description

Technical field

[0001] The utility model relates to a strap structure for a baby carriage. [Background Technology]

[0002] A child stroller generally comprises a stroller frame and a seat assembly arranged on the stroller frame. To facilitate carrying the child stroller, most child strollers are foldable.

[0003] Existing strollers are often equipped with shoulder straps for easy carrying after folding. However, when unfolded, the shoulder straps are loose and may get stuck in the stroller, affecting its normal use. In addition, the shoulder straps are long and can easily drag on the ground and get dirty when pushed.

[0004] In some strollers, the shoulder straps are arranged toward one side of the stroller frame, which can easily cause the stroller to swing when the stroller is carried on the shoulder, thereby affecting the carrying effect.

[0005] For this reason, the present invention is studied and proposed in view of the above problems. [Utility Model Content]

[0006] The utility model aims to overcome the deficiencies of the prior art and provides a strap structure for a children's stroller, wherein the strap is located between a front leg assembly, a rear leg assembly and a seat frame; when the frame is unfolded, the strap is in a tensioned state, thereby preventing the strap from getting stuck on the frame during use and affecting normal pushing and use, and also preventing the strap from being dragged on the ground and getting dirty; when the frame is folded, the strap is in a relaxed state and can be pulled out of the frame to form a carrying portion, thereby facilitating use.

[0007] The utility model is realized through the following technical solutions:

[0008] A harness structure for a children's stroller includes a frame 1 with an expanded state and a folded state, the frame 1 including a seat frame 4 that can be folded and expanded accordingly, a front foot assembly 2 with two front foot rods, a rear foot assembly 3 with two rear foot rods, and a harness 5 with a first connecting end 51 and a second connecting end 52 that is integrally formed, the first connecting end 51 of the harness 5 being connected to one front foot rod, the portion of the harness 5 near the first connecting end 51 being movably connected to one rear foot rod, the second connecting end 52 of the harness 5 being connected to the other front foot rod, and the portion of the harness 5 near the second connecting end 52 being movably connected to the other rear foot rod; the middle portion of the harness 5 is wrapped around the seat frame 4; when the frame 1 is in the expanded state, the front foot assembly 2 and the rear foot assembly 3 are relatively spread apart, so that the harness 5 is in a tensioned state; when the frame 1 is in the folded state, the front foot assembly 2 and the rear foot assembly 3 are relatively closed, so that the harness 5 is in a relaxed state so that it can be pulled out of the frame 1 to form a carrying portion 53.

[0009] In the above-mentioned baby stroller strap structure, the corresponding portion of the strap 5 is slidably connected to the rear leg rod.

[0010] In the above-mentioned baby stroller strap structure, each of the rear leg rods is provided with a sliding connector 31 for slidably connecting a corresponding portion of the strap 5 .

[0011] In the above-mentioned baby stroller strap structure, the sliding connector 31 is relatively fixedly arranged at the lower part of the rear leg assembly 3 , and the sliding connector 31 has a guide hole 311 for the strap 5 to pass through.

[0012] In the above-mentioned baby stroller strap structure, at least the middle portion of the strap 5 is flat.

[0013] In the above-mentioned baby stroller strap structure, the strap 5 is a flexible braided strap.

[0014] As described above, in a baby stroller strap structure, sliding guide grooves 41 are provided on both sides of the seat frame 4 for limiting and guiding the corresponding parts of the strap 5 to pass through. When the frame 1 is in the unfolded state, the middle part of the strap 5 is tightly attached to the upper surface of the seat frame 4; when the frame 1 is in the folded state, the middle part of the strap 5 can be pulled away from the upper surface of the seat frame 4 to form a carrying portion 53.

[0015] In the baby stroller's strap structure, a fixing connector 21 for connecting to the end of the strap 5 is provided at the lower portion of each front leg rod.

[0016] In the strap structure of the baby stroller, the front end of the strap 5 is riveted, buckled or clamped to the lower part of the front leg rod through a fixed connector 21.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. The utility model connects and winds the shoulder straps between the front foot assembly, the rear foot assembly and the seat frame, and accordingly tightens or relaxes the shoulder straps when the frame is unfolded or folded. That is, when the frame is unfolded, the shoulder straps are in a tensioned state, which prevents the shoulder straps from getting stuck on the frame during use and affecting normal use, and also prevents the shoulder straps from being dragged on the ground and getting dirty. When the frame is folded, the shoulder straps are in a relaxed state, and the shoulder straps on the seat frame can be easily pulled out of the frame to form a carrying portion, which is convenient for use.

[0019] 2. In order to facilitate the smooth sliding of the shoulder strap, a sliding connector is provided on the rear foot rod for slidably connecting the corresponding parts of the shoulder strap.

[0020] 3. In order to facilitate lifting or shoulder carrying, at least the middle part of the shoulder strap is flat.

[0021] 4. The part of the shoulder strap wrapped around the seat frame is exactly the middle part of the shoulder strap. When the entire frame is folded, the user pulls it out from the rear of the seat frame to form a carrying part, which is convenient to use. Since the carrying part is the middle part of the shoulder strap, when the user lifts it vertically or carries it on the shoulder, the center of gravity of the folded frame is located on the vertical line passing through the midpoint of the carrying part, which has the characteristic of stable left and right force and avoids swinging. At the same time, the two ends of the shoulder strap keep pulling the front leg rod, so that the frame remains in a folded state and the front leg rod is prevented from spreading out.

[0027] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0028] like Figure 1-4As shown, the utility model is a baby stroller strap structure, comprising a frame 1 with an expanded state and a folded state, the frame 1 comprising a seat frame 4 that can be folded and expanded accordingly, a front foot assembly 2 with two front foot rods, a rear foot assembly 3 with two rear foot rods, and a shoulder strap 5 having a first connecting end 51 and a second connecting end 52 and being integrally formed. The first connecting end 51 of the shoulder strap 5 is connected to a front foot rod, and the portion of the shoulder strap 5 near the first connecting end 51 is movably connected to a rear foot rod. The second connection end 52 of 5 is connected to the other front foot rod, and the part of the shoulder strap 5 close to the second connection end 52 is movably connected to the other rear foot rod; the middle part of the shoulder strap 5 is wrapped around the rear side of the seat frame 4; when the frame 1 is in the expanded state, the front foot assembly 2 and the rear foot assembly 3 are relatively opened, so that the shoulder strap 5 is in a tensioned state; when the frame 1 is in the folded state, the front foot assembly 2 and the rear foot assembly 3 are relatively closed, so that the shoulder strap 5 is in a relaxed state so that it can be pulled out of the frame 1 to form a back portion 53. The utility model connects and wraps the shoulder strap between the front foot assembly, the rear foot assembly and the seat frame, and uses the expansion or folding of the frame to tension or relax the shoulder strap accordingly, that is, when the frame is expanded, the shoulder strap is in a tensioned state, which prevents the shoulder strap from getting stuck on the frame during use and affecting normal use, and also prevents the shoulder strap from being dragged to the ground and getting dirty, such as Figure 2 When the frame is folded, the straps are in a relaxed state, and the straps on the seat frame can be easily pulled out of the frame to form a back portion, such as Figure 3 、 4 As shown, easy to use.

[0029] In addition, since the part of the shoulder strap wrapped around the seat frame is exactly the middle part of the shoulder strap, when the entire frame is folded, the rear part of the seat frame is exposed upward, so the user can easily pull out the middle part of the shoulder strap to form a carrying part, which is convenient to use; and the carrying part is the middle part of the shoulder strap, so when the user lifts it vertically or carries it on the shoulder, the center of gravity of the folded frame is located on the vertical straight line passing through the midpoint of the carrying part, and when the user lifts it vertically or carries it on the shoulder, the force on the left and right is stable and the deviation is avoided; at the same time, the two ends of the shoulder strap keep pulling the front leg rod, so that the frame remains in a folded state and the front leg rod is prevented from spreading out.

[0030] like Figure 1-4 As shown, the upper end of the front foot assembly 2 is rotatably connected to the upper end of the rear foot assembly 3, the lower end of the push rod assembly is rotatably connected to the upper end of the front foot assembly 2 or the upper end of the rear foot assembly 3, and the rear side of the seat frame 4 is rotatably connected to the upper end of the front foot assembly. When the push rod assembly is tilted downward relative to the rear foot assembly and folded, it can drive the front foot assembly to rotate and move closer to the rear foot assembly, or it can drive the seat frame to rotate and move closer to the front foot assembly.

[0031] like Figure 1-4 As shown, in order to facilitate smooth sliding of the shoulder strap, the corresponding portion of the shoulder strap 5 is slidably connected to the rear foot rod.

[0032] like Figure 1-4 As shown, in order to facilitate the smooth sliding of the shoulder strap, each of the rear foot rods is provided with a sliding connector 31 for slidably connecting the corresponding part of the shoulder strap 5. The sliding connector 31 is relatively fixedly arranged at the lower part of the rear foot assembly 3, and the sliding connector 31 has a guide hole 311 for the shoulder strap 5 to pass through. In this embodiment, the guide hole 311 can guide and limit the sliding path of the shoulder strap 5, ensuring that the shoulder strap slides smoothly along the set direction and ensures normal use. Among them, as Figure 1-4 As shown, the guide hole 311 is a long hole, which can limit the strap from turning over and changing direction during use, ensuring smooth sliding of the strap.

[0033] like Figure 1 、 3 As shown, at least the middle portion of the shoulder strap 5 is flat, which effectively increases the contact area between the shoulder strap and the human body during lifting or shoulder carrying, thereby avoiding being strangled and improving the comfort of the user when lifting or shoulder carrying.

[0034] In order to improve the connection stability and grip comfort of the shoulder strap, the shoulder strap 5 is a flexible braided strap.

[0035] like Figure 1-4 As shown, in order to facilitate the smooth sliding of the shoulder strap, sliding guide grooves 41 are provided on both sides of the seat frame 4 for limiting and guiding the corresponding parts of the shoulder strap 5 to pass through. When the frame 1 is in the unfolded state, the middle part of the shoulder strap 5 is tightly attached to the upper surface of the seat frame 4; when the frame 1 is in the folded state, the middle part of the shoulder strap 5 can be pulled away from the upper surface of the seat frame 4 to form a back-mounted portion 53.

[0036] like Figure 1-3 As shown, in order to facilitate the convenient and reliable connection between the front end of the strap 5 and the front foot rod, the lower part of each front foot rod is provided with a fixing connector 21 for connecting to the end of the strap 5. The front end of the strap 5 is riveted, buckled or clamped to the lower part of the front foot rod through the fixing connector 21.
