[0003] The utility model discloses a foldable stroller auxiliary wheel which overcomes the defects in the prior art.
[0004] To solve the above technical problem, the utility model discloses a foldable stroller auxiliary wheel, which comprises a shell seat, a wheel embedding groove arranged on the upper side of the shell seat and an arm rod embedding groove arranged on the lower side of the shell seat, the arm rod embedding groove is communicated with the wheel embedding groove, a main shaft with an axis extending forward and backward is arranged in the arm rod embedding groove, an arm rod capable of being hidden in the arm rod embedding groove is rotatably connected to the main shaft, a wheel capable of being hidden in the wheel embedding groove is rotatably connected to the arm rod, an auxiliary arm extending into the shell seat and rotating is arranged at the end of the arm rod away from the wheel, a locking hole is arranged on the auxiliary arm, a first spring draw pin and a second elastic draw pin capable of being inserted into the locking hole are arranged on the shell seat.
[0005] The utility model further sets up that when the wheel is unfolded to the use state, the pin shaft on the first spring draw pin is inserted into the locking hole, and when the wheel is folded to the non-use state, the pin shaft on the second elastic draw pin is inserted into the locking hole.
[0006] The utility model further sets up that when the wheel is folded to the non-use state, a brush with bristles is arranged in the wheel embedding groove to tightly abut the wheel surface of the wheel.
[0007] In summary, the utility model has the following beneficial effects:
[0008] 1. No need to disassemble and assemble, convenient to unfold and fold.
[0009] 2. The wheel in the folded state can be self-cleaned, and the cleaning effect is good. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is the overall structure schematic diagram of the utility model;
[0011] Figure 2 It is the structure schematic diagram of another state of the utility model;
[0012] Figure 3This is a partial structural schematic diagram of the present invention. Detailed Implementation
[0013] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0015] Example 1
[0016] See Figures 1 to 3 As shown, the foldable stroller auxiliary wheel involved in this embodiment includes a housing 1. The side of the housing 1 is provided with a wheel mounting groove 2 arranged at the top and an arm mounting groove 3 arranged at the bottom. The arm mounting groove 3 is connected to the wheel mounting groove 2. The arm mounting groove 3 is provided with a main shaft 4 extending back and forth. An arm 5 that can be retracted into the arm mounting groove is rotatably connected to the main shaft 4. A wheel 6 that can be retracted into the wheel mounting groove is rotatably connected to the arm 5. The end of the arm 5 facing away from the wheel is provided with an auxiliary arm 7 that extends into the housing and rotates. A locking hole 8 is provided on the auxiliary arm 7. The housing 1 is provided with a first spring pull pin 9 and a second elastic pull pin 10 that are inserted into the locking hole.
[0017] Furthermore, when the wheel 6 is unfolded to the use state, the pin on the first spring pull pin 9 is inserted into the locking hole 8; when the wheel 6 is folded to the non-use state, the pin on the second elastic pull pin 10 is inserted into the locking hole 8.
[0018] In this implementation plan, firstly, the auxiliary wheels of the stroller, such as Figure 1 To unfold the stroller from its folded state, pull out the pin on the second elastic pin 10 from the locking hole 8. Then rotate the arm 5 until it is close to the first spring pin 9. Pull the first spring pin 9 so that its upper pin moves away from the auxiliary arm 7. When the locking hole 8 and the pin on the first spring pin 9 are aligned on the same axis, release the first spring pin 9. The upper pin will then return to its original position under the action of elasticity and insert into the locking hole 8, thus limiting the rotation of the auxiliary arm 7 and the arm 5, allowing the stroller's auxiliary wheels to move from the folded state to the unfolded state. Figure 1 The state shown transforms into the state shown in the figure. Figure 2 The status function is shown.
[0019] Example 2
[0020] SeeFigures 1 to 3 As shown, the foldable stroller auxiliary wheel of the present embodiment is further provided with a bristle brush 11 in the groove of the wheel 6 when the wheel 6 is folded to the non-use state.
[0021] In the present embodiment, when the wheel 6 is folded to the non-use state, the bristles of the brush 11 are used to brush the surface of the wheel by driving the wheel 11 to rotate by external force, so as to clean and expose the original anti-skid lines, and clean the dirt in the groove between the anti-skid lines.
[0022] The foldable stroller auxiliary wheel of the present embodiment does not need to be disassembled and is convenient to fold and unfold, and the wheel in the folded state can be self-cleaning, has good cleaning effect, perfect overall function and strong practicability.
