[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] First embodiment

[0023] Please refer to Figure 1-Figure 3 In the first embodiment of the present invention, the height adjustment structure of the baby stroller handle includes: a handle 1, two upper joints 2 and two lower joints 3, wherein the two upper joints 2 are fixedly mounted on the two ends of the handle 1, and the two upper joints 2 are respectively buckled with the two lower joints 3, and the two upper joints 2 are inlaid with upper joint reinforcement iron plates 4, and the two lower joints 3 are inlaid with lower joint reinforcement iron plates 5, one end of the two upper joint reinforcement iron plates 4 is respectively buckled on the two lower joint reinforcement iron plates 5, and the corresponding upper joints 2, lower joints 3, upper joint reinforcement iron plates 4 and lower joint reinforcement iron plates 5 are riveted by rivets 18, and a protective cover is buckled on one side of the two upper joints 2.

[0024] The working principle of the height adjustment structure of the baby stroller handle provided by the utility model is as follows:

[0025] During assembly, first embed the two upper joint reinforcement iron plates 4 into the two upper joints 2 respectively, and then embed the two lower joint reinforcement iron plates 5 into the two lower joints 3 respectively. Subsequently, the upper joints 2 and the lower joints 3 are riveted together by rivets 18. In this way, a stable connection joint can be formed without looseness.

[0026] Compared with the related art, the baby stroller handle height adjustment structure provided by the present invention has the following beneficial effects:

[0027] This device makes the connection between the upper joint 2 and the lower joint 3 tighter and more stable by setting the upper joint reinforcement iron plate 4 and the lower joint reinforcement iron plate 5, so that looseness will not occur, thereby ensuring the stability of the baby carriage during the pushing process.

[0028] Second embodiment:

[0029] Based on the baby stroller handle height adjustment structure provided in the first embodiment of the present application, the second embodiment of the present application provides another baby stroller handle height adjustment structure. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0030] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and implementation methods.

[0031] Please refer to Figure 4 The height adjustment structure of the baby stroller handle also includes two load-bearing main beams 6, each of which is provided with an active cavity 7, and each of which is provided with a telescopic arm 8. The tops of the two telescopic arms 8 extend above the two load-bearing main beams 6 and are fixedly connected to the corresponding lower joints 3, and the two telescopic arms 8 are respectively slidably connected to the tops of the two load-bearing main beams 6. The sliding connection is achieved by providing through-holes on the tops of the two load-bearing main beams 6, and the two through-holes are respectively communicated with the two active cavities 7. The two telescopic arms 8 pass through the two through-holes and contact the inner walls of the through-holes. In addition, a limiting card plate is fixed at the bottom of the two telescopic arms 8, and the outer dimensions of the limiting card plate are larger than the diameter of the through-opening, thereby preventing the telescopic arm 8 from separating from the load-bearing main beam 6. A plurality of transverse slots 9 are provided on the side where the two telescopic arms 8 are close to each other. The same reinforcing beam 10 is fixedly installed on the outer wall of the side where the two load-bearing main beams 6 are close to each other. A vertical plate 11 is fixedly installed on the top of the reinforcing beam 10, and a locking rod 12 is slidably installed on the two vertical plates 11. The ends of the two locking rods 12 that are away from each other extend into the corresponding transverse slot 9, thereby forming a locking effect on the telescopic arm 8.

[0032] In the above manner, in order to ensure that the embedded rod 12 is tightly inserted into the transverse slot 9, a linkage folding strip 13 is fixedly installed at the end of the two embedded rods 12 close to each other, and a compression spring 14 is sleeved on the two embedded rods 12. The ends of the two compression springs 14 close to each other are fixedly connected to the two linkage folding strips 13, and the ends away from each other are fixedly connected to the two vertical plates 11. A threaded column 15 is threadedly installed on the reinforcing beam 10, and a trapezoidal plate 16 is rotatably installed on the top of the threaded column 15. The trapezoidal plate 16 is rotatably installed on the trapezoidal plate 1 6 are respectively in conflict with the two linkage folding strips 13, and two movable holes are opened on the reinforcing beam 10. Two elastic clips 17 are fixedly installed on the bottom of the trapezoidal plate 16. The two elastic clips 17 respectively pass through the two movable holes, and the two elastic clips 17 are buckled with the bottom of the reinforcing beam 10. The elastic clip 17 is a common elastic holding component on the market, with a wedge-shaped protrusion, so that it can form a mutual card position with the bottom of the reinforcing beam 10, thereby preventing the threaded column 15 from rotating under normal conditions.

[0033] In this embodiment, in order to ensure that the locking rod 12 can only move linearly, transverse limiting rods are slidably installed on both vertical plates 11 , and the ends of the two transverse limiting rods close to each other are fixedly connected to the two linkage folding strips 13 respectively.

[0034] In this embodiment, in order to ensure that the trapezoidal plate 16 can only move in a vertical direction when the threaded column 15 rotates, a vertical limit rod is fixedly installed at the bottom of the trapezoidal plate 16. The vertical limit rod is located at the rear bottom of the trapezoidal plate 16. Figure 4 As shown, it is blocked by the threaded column 15, and the vertical limiting rod passes through the reinforcing beam 10 and is slidably connected to the reinforcing beam 10. This limiting method is a common operation and will not be described in detail here.

[0035] In this embodiment, in the initial state, the two compression springs 14 are in a compressed state;

[0036] When the height of the push handle 1 needs to be adjusted, first pinch the two elastic clips 17 in the direction of approaching each other to separate the two elastic clips 17 from the bottom of the reinforcing beam 10, and then directly turn the threaded column 15 clockwise. Under the action of the vertical limit rod, the threaded column 15 will rise with the trapezoidal plate 16, and the two elastic clips 17 will enter the corresponding movable holes. At this time, the trapezoidal plate 16 gradually removes the pushing force on the two linked folding strips 13. At the same time, the two linked folding strips 13 approach each other under the rebound of the tightening spring 14, and finally the two embedded rods 12 are moved out of the corresponding horizontal slots 9, and then the push handle 1 is pulled upward to move the telescopic arm 8 out of the movable cavity 7 until it is pulled out. After the specified length, the threaded column 15 is rotated counterclockwise, and the trapezoidal plate 16 begins to descend. When its two sides contact the two linkage folding strips 13 respectively, it will push the two linkage folding strips 13, so that the two embedded rods 12 move away from each other and finally insert into the corresponding transverse slots 9, thereby realizing the positioning restriction of the telescopic arm 8. At the same time, in the process of the trapezoidal plate 16 descending, the elastic clip 17 will contact the top edge of the movable hole, so that it can automatically deform and enter the movable hole, until the embedded rod 12 is inserted into the transverse slot 9, the elastic clip 17 automatically returns to its original state and mutually constrains with the bottom of the reinforcing beam 10 to form a clamping effect, effectively preventing the threaded column 15 from rotating.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
