[0038] See the example. Figure 1-10 :

[0039] A telescopic push rod structure for an infant carrier includes a pusher 3, an anti-rotation component 6, a mounting component 2, and a rod body 1. The rod body 1 includes a lower end housing 10, a telescopic sleeve 12, and a handle 13. The lower end housing 10 is rotatably mounted on the mounting component 2. An outer tube 11 for accommodating the telescopic sleeve 12 extends from the upper end of the lower end housing 10. The handle 13 is connected to the upper end of the telescopic sleeve 12. The pusher 3 is arranged on the handle 13.

[0040] The push part 3 is connected to the plug 5 via the pull rope 4. The plug 5 is arranged inside the telescopic sleeve 12 of the rod body 1. The bottom of the plug 5 is provided with a V-shaped plug 50. The moving block 7 is located directly below the plug 5 and is provided with a slanted mating surface 70 corresponding to the V-shaped plug 50. A second spring 71 is arranged inside the moving block 7. When the plug 5 moves downward, the V-shaped plug 50 at the bottom of the plug 5 contacts the slanted mating surface 70, pushing the moving block 7 inward. When the moving block 7 is not pressed or blocked, the moving block 7 returns to its original position under the action of the second spring 71.

[0041] The outer surface of the mounting component 2 is provided with several limiting grooves 20 along the circumferential direction. One end of the anti-rotation component 6 is provided with a limiting block 60 corresponding to the limiting groove 20, and the other end of the anti-rotation component 6 is provided with a stop block 61. The moving block 7 is located in front of the stop block 61. The anti-rotation component 6 is rotatably mounted on the outside of the mounting component 2. A third spring 62 is provided between the anti-rotation component 6 and the mounting component 2. The limiting block 60 and the third spring 62 are respectively located on both sides of the rotation center of the anti-rotation component 6. A pressing protrusion 63 is provided on the upper part of the anti-rotation component 6, and the pressing protrusion 63 and the third spring 62 are located on the same side. Preferably, a semi-circular concave portion is provided on the inner side of the anti-rotation component 6, and the radius of the semi-circular concave portion is the sum of the radius of the mounting component 2 and the installation distance between the anti-rotation component 6 and the mounting component 2.

[0042] In one embodiment, the lower housing 10 is provided with a first rotating post 64 for mounting the anti-rotation member 6 and a second rotating post 72 for mounting the movable block 7. The anti-rotation member 6 can rotate around the second rotating post 72. A second spring 71 is sleeved on the second rotating post 72. The first rotating post 64 and the second rotating post 72 are arranged parallel to the axis of the mounting member 2. The lower housing 10 is provided with a side opening for easy pressing of the anti-rotation member 6. Preferably, the lower housing 10 includes an inner housing 14 and an outer housing 15, with a receiving cavity arranged between the inner housing 14 and the outer housing 15. The first rotating post 64 and the second rotating post 72 are arranged in the inner housing 14.

[0043] In one embodiment, the lower housing 10 includes an inner housing 14 and an outer housing 15, which are connected by screws. The first rotating column 64 and the second rotating column 72 are arranged in the inner housing 14 to facilitate the installation of the moving block 7 and the anti-rotation member 6 into the lower housing 10.

[0044] In use, the limiting block 60 of the anti-rotation member 6 is inserted into the limiting groove 20 on the outer side of the mounting member 2, locking and restricting the rotation of the lower housing 10. That is, the rod body 1 cannot rotate at this time. The stop block 61 at the other end of the anti-rotation member 6 is located in front of the moving block 7. When the pressing protrusion 63 of the anti-rotation member 6 is pressed, the limiting block 60 is dislodged from the limiting groove 20. The stop block 61 blocks the moving block 7 downward as the anti-rotation member 6 rotates. At this time, the rod body 1 can be rotated. When it is rotated to the desired position, the limiting block 60 is aligned with the other limiting groove 20. The anti-rotation member 6 is released, and the anti-rotation member 6 is reset under the elastic force of the third spring 62. The limiting block 60 is then inserted into the limiting groove 20.

[0045] In one embodiment, the mounting component 2 is arranged on the outside of the basket body 8, and a support frame is arranged at the bottom of the basket body 8, with casters at the bottom of the support frame. When the rod body 1 rotates to the rear side of the basket body 8, the user can push the basket body 8 through the rod body 1.

[0046] In one embodiment, the actuating part 3 includes a button 30 and a connecting block 33. The lower end of the button 30 is connected to the handle part 13 via a fourth spring 31. Second inclined through grooves 32 are provided on both sides of the lower end of the button 30, with the second inclined through grooves 32 tilted towards the button 30. The connecting block 33 is provided with a connecting post 34 located within the second inclined through groove 32. A pull rope 4 is connected to the rear end of the connecting block 33. It is understood that a cavity for accommodating the fourth spring 31 is provided in the middle of the lower end of the button 30. When the user manually presses the button 30, the connecting post 34 moves upward relative to the second inclined through groove 32, thereby causing the connecting block 33 to move towards the button 30.

[0047] In one embodiment, the insert block 5 has a limiting protrusion 51 on its side, and the telescopic sleeve 12 has a limiting hole 17 corresponding to the limiting protrusion 51. A cavity is recessed on one side of the insert block 5, and a sliding member 53 is movably installed within the cavity. The top of the sliding member 53 is connected to the inner top surface of the cavity via a first spring 54. The lower end of the pull rope 4 is connected to the sliding member 53. A limiting post 55 is provided inside the sliding member 53. A locking plate 56 is provided between the sliding member 53 and the insert block 5. The locking plate 56 has a first inclined through groove 57, and the sliding member 53 is placed within the first inclined through groove 57. The insert block 5 and the telescopic sleeve 12 have inner openings 58 corresponding to the locking plate 56. The first inclined through groove 57 is inclined towards the inner opening 58. The outer tube 11 of the lower housing 10 has several limiting slots 16 corresponding to the inner opening 58.

[0048] In one embodiment, the top of the sliding member 53 and the inner top surface of the cavity are respectively provided with a placement post 59 for placing the first spring 54.

[0049] In one embodiment, the upper end of the limiting protrusion 51 is provided with a mating inclined surface, and the side wall of the insertion block 5 is recessed with a U-shaped through groove 52. The limiting protrusion 51 is arranged on the side wall inside the U-shaped opening of the U-shaped through groove 52, which facilitates the installation of the insertion block 5 inside the telescopic sleeve 12.

[0050] When the pull rope 4 drives the sliding member 53 to rise, the limiting post 55 on the inner side of the sliding member 53 moves upward relative to the locking plate 56. The limiting post 55 moves to the inclined top of the first inclined through groove 57, causing the locking plate 56 to move away from the inner opening 58. As the locking plate 56 moves inward and disengages from the limiting slot 16, the limitation between the telescopic sleeve 12 and the lower housing 10 is released. Then, the user pulls the handle 13 outward, extending the telescopic sleeve 12 out of the outer tube 11. As the limiting slot 16 of the telescopic sleeve 12 aligns with the other limiting slot 16, the upward pulling force of the pull rope 4 on the sliding member 53 is eliminated. The sliding member 53 resets downward under the action of the first spring 54, causing the limiting post 55 to move downward from the inclined top of the first inclined through groove 57, driving the locking plate 56 to move towards the inner opening 58, causing the locking plate 56 to move outward and insert into the limiting slot 16.

[0051] In one embodiment, the pull rope 4 includes a rope sleeve 40, within which a rope body 41 is installed. The rope body 41 has fixed ends 42 at both ends. The sliding member 53 and the connecting block 33 of the pressing part 3 are respectively provided with placement grooves corresponding to the fixed ends 42. The cavities of the handle part 13 and the insert block 5 are respectively provided with sleeve placement parts 43, which are used to place the ends of the rope sleeve 40. It can be understood that the pull rope 4 is connected to the sliding member 53 after passing through the handle part 13 and the telescopic sleeve 12.

[0052] In one embodiment, the rope sleeve 40 is a rigid rope sleeve.

[0053] In one embodiment, the handle 13 is further provided with a push-to-place portion 18 for accommodating the button 30 and a second placement portion for accommodating the connecting block 33, wherein the push-to-place portion 18 is connected to the second placement portion.

[0054] The working principle of this embodiment:

[0055] The limiting block 60 of the anti-rotation component 6 is inserted into the limiting groove 20 on the outer side of the mounting component 2, locking and limiting the rotation of the rod body 1. The stop block 61 at the other end of the anti-rotation component 6 is located in front of the moving block 7 and does not affect the forward and backward movement of the moving block 7. At this time, when the user manually presses the button 30, the connecting column 34 moves towards the top of the second inclined through groove 32, thereby causing the connecting block 33 to move towards the button 30 side. The rope body 41 of the pull rope 4 pulls the sliding component 53 upward, and the inner side of the sliding component 53... The limiting post 55 moves upward relative to the locking plate 56. The limiting post 55 moves to the inclined top of the first inclined through groove 57. The locking plate 56 moves inward and disengages from the limiting slot 16, releasing the limitation between the telescopic sleeve 12 and the outer tube 11. Then, the user pulls the handle 13 outward to extend the telescopic sleeve 12 out of the outer tube 11. As the limiting slot 16 of the telescopic sleeve 12 aligns with another limiting slot 16, the button 30 is manually released. The sliding member 53 moves downward, causing the locking plate 56 to move outward and lock in the limiting slot 16.

[0056] If the user manually releases button 30, the slider 53 returns to its original position under the action of the first spring 54, causing the limiting post 55 to move down from the inclined top of the first inclined through groove 57, which in turn moves the locking plate 56 toward the inner opening 58, causing the locking plate 56 to move outward and insert into the limiting slot 16; if the user pushes the handle 13 back inward, the telescopic sleeve 12 retracts into the outer tube 11, and the plug 5 moves downward through the rope tube sleeve 40 of the pull rope 4, and the V-shaped plug 50 at the bottom of the plug 5 contacts the inclined mating surface 70, pushing the moving block 7 toward its inward.

[0057] Understandably, when the insert 5 moves upward, that is, when the telescopic sleeve 12 extends out of the outer tube 11, the moving block 7 blocks the front end of the stop block 61 of the anti-rotation member 6, making it impossible for the user to press the pressing protrusion 63 of the anti-rotation member 6. As a result, the limiting block 60 of the anti-rotation member 6 cannot disengage from the limiting groove 20 on the outer side of the mounting member 2. At this time, the rod body 1 cannot be rotated.

[0058] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
