[0003] According to the Chinese patent publication number: CN210338030U, a safety fence for a baby stroller includes a left fence and a right fence rotatably connected to the baby stroller, and also includes a clamping structure fixed to the baby stroller, the clamping structure includes a mounting sleeve that is sleeved with the baby stroller and reinforced with bolts, and a connecting sleeve integrally formed with the mounting sleeve, the connecting sleeve is provided with a pressing through hole, the pressing through hole is slidably connected with a pressing piece, the connecting sleeve is provided with an elastic piece for applying an external thrust to the pressing piece, the pressing piece is provided with two wing plates at the inner end of the connecting sleeve, the two wing plates are provided with embedding blocks, the left fence and the right fence are both provided with a plug-in sleeve that is plug-matched with the connecting sleeve, and the inner surface of the plug-in sleeve is provided with an embedding groove for embedding the embedding block.

[0004] In the above scheme, the fence is opened and closed by horizontally rotating left and right fences, which still has the following disadvantages: the horizontally rotating left and right fences will be unfolded to two sides respectively when opened, which increases the space occupied by the three-wheeled baby carriage. When children sit on the three-wheeled baby carriage, they need to go around the unfolded fences, which reduces the convenience of the three-wheeled baby carriage when in use. Utility Model Content

[0005] The utility model aims to provide a safety fence for a three-wheeled baby carriage, so as to solve the problem that when a child sits on the three-wheeled baby carriage, the child needs to go around the unfolded fence, which reduces the convenience of the three-wheeled baby carriage when in use.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a safety fence for a three-wheeled baby carriage, including a seat cushion, a backrest slidably arranged above the seat cushion, fixed columns are respectively fixed on both sides of the backrest, a rotating cylinder is rotatably inserted on the fixed column, a blocking plate is fixed to one end of the fixed column, a fence is fixed to the surface of the rotating cylinder, a mounting plate is fixed to the top surface of the backrest, and an elastic headrest is fixed at the connection between the backrest and the mounting plate.

[0007] Preferably, a storage groove is provided on the top surface of the fence, a sliding plate is slidably provided inside the storage groove, and a push bar is fixed on the top surface of the sliding plate.

[0008] Preferably, sliding grooves are respectively provided on both sides of the storage groove, sliding bars are respectively fixed on both sides of the sliding plate, and the sliding grooves and the sliding bars are slidably arranged.

[0009] Preferably, a support column is fixed to the top surface of the seat cushion, a limit folding plate is fixed to the top end of the support column, and the limit folding plate and the fence are slidably arranged.

[0010] Preferably, a support plate is fixed on one side of the seat cushion, a mounting groove is provided on one side of the backrest, an insertion plate is fixed on the inner top surface of the mounting groove, a plurality of through holes are provided on one side of the insertion plate, an adjustment groove is provided on the top surface of the support plate, and the adjustment groove and the insertion plate are slidably inserted.

[0011] Preferably, a plurality of through holes are opened on one side of the insertion plate, a plurality of fixing holes are opened on both sides of the inside of the adjustment slot, a fixing pin is slidably inserted into the inside of the fixing hole, and one end of the fixing pin passes through the fixing hole and is slidably inserted with the through hole.

[0012] Compared with the prior art, a three-wheeled baby carriage safety fence adopting the above technical solution has the following advantages:

[0013] Beneficial effects:

[0014] 1. When a child is riding on a three-wheeled stroller, the parent will first push the fence upwards to rotate the fence around the fixed column, so that the fence can overlap with the backrest and be placed vertically. Since the fence is in a vertical state, it will not occupy any additional space other than that of the three-wheeled stroller when it is unfolded, thus preventing the child from having to take a detour due to the extra space occupied. This makes it easier for the child to climb onto the seat cushion, thereby increasing the convenience of the child when using the three-wheeled stroller.

[0015] Second, the fence in the horizontal state is inside the limit folding plate, and the support column can be used to support the fence in the current position. In order to keep the two fences moving synchronously, the staff will push the sliding plate to slide inside the storage slot, and the two ends of the sliding plate can be slid into the inside of the two storage slots respectively, so that the two fences can be connected, so that the two fences can move synchronously, which is convenient for pushing the two fences to move at the same time;

[0016] 3. Before using the three-wheeled stroller, parents will first adjust the height of the backrest according to the height of the child. The staff will first pull out the fixing pin from the fixing hole, and then push the backrest upward. The upward moving backrest will drive the plug-in plate to move upward inside the adjustment slot to adjust the height of the backrest. After determining the height of the backrest, the staff will re-fix the fixing pin inside the penetration hole, which increases the comfort of the child when using the three-wheeled stroller.
