DETAILED DESCRIPTION

[0035] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described. Example 1

[0036] like Figures 1 to 5 As shown, the retractable door stopper disclosed in this embodiment comprises two partition pieces 1, a connecting component and a ratchet mechanism, wherein the connecting component slidably connects one partition piece 1 to the other partition piece 1, at least one rack 2 is provided on the surface of one partition piece 1, and a through groove 3 is provided on the surface of the other partition piece 1, a gear 4 is rotatably connected in the through groove 3, the gear 4 is meshed with the rack 2, the ratchet mechanism is arranged in the through groove 3 and connected to the gear 4, and is used to drive the gear 4 to move in a first direction, when the ratchet mechanism rotates counterclockwise to a preset angle, the ratchet mechanism disengages from the gear 4, and the gear 4 moves in a second direction, under the drive of the ratchet mechanism, the gear 4 moves in the first direction, driving one partition piece 1 to move in the first direction, so that the door stopper is extended; the ratchet mechanism is rotated counterclockwise to a preset angle, so that the ratchet mechanism disengages from the gear 4, and the gear 4 can move in the second direction, and the user can push one partition piece 1 to move in the second direction, so that the door stopper is shortened, so that the door stopper can be suitable for door openings and aisles of different widths.

[0037] like Figures 1 to 5As shown, the ratchet mechanism includes a ratchet 5, a first pawl 6, a paddle 7, and a braking component. The ratchet 5 is arranged in the through slot 3 and is coaxially connected between the gears 4. The paddle 7 is rotatably connected in the through slot 3. The first pawl 6 is rotatably connected to the back of the paddle 7 and meshes with the ratchet 5. The braking component is rotatably connected in the through slot 3 and is used to limit the counterclockwise rotation of the gear 4. The paddle 7 is rotated counterclockwise to drive the first pawl 6 to slide over the back of the ratchet 5 teeth. Under the action of the braking component, the ratchet 5 is stationary at this time. Then the paddle 7 is rotated clockwise to make the first pawl 6 push the ratchet 5 to rotate clockwise, and the driving gear 4 drives a partition piece 1 to move in the first direction to extend the door stop.

[0038] like Figures 1 to 5 As shown, the braking component includes a second pawl 8, which is rotatably connected to the through slot 3, and is meshed with the ratchet 5. The second pawl 8 is arranged opposite to the first pawl 6. When the first pawl 6 slides over the back of the teeth of the ratchet 5, the second pawl 8 remains meshed with the ratchet 5, so that the ratchet 5 remains stationary. When the first pawl 6 pushes the ratchet 5 to rotate clockwise, the second pawl 8 slides over the back of the teeth of the ratchet 5, so that the door stopper can be stably extended.

[0039] In addition, through the cooperation between the first pawl 6 and the second pawl 8, the ratchet 5 can be stationary without the action of external force, that is, the gear 4 can be positioned on the rack 2, so that the door stop has a self-locking function, which is convenient for users to use.

[0040] The first pawl 6 and the second pawl 8 are meshed with the ratchet wheel 5 through the torsion force of the torsion spring.

[0041] like Figures 1 to 5 As shown, an opening 10 is provided on the paddle 7, a top block 11 is provided in the opening 10, and limiting grooves 9 are provided on both sides of the second pawl 8. When the paddle 7 is rotated counterclockwise to a preset angle, the top block 11 is connected to the limiting groove 9, and the paddle 7 is rotated counterclockwise to a preset angle, so that the top block 11 is stuck in the bottom of the limiting groove 9, and the second pawl 8 is pushed away from the ratchet 5. At this time, the first pawl 6 is disengaged from the ratchet 5, and the gear 4 can move in the second direction, that is, the user can push a partition piece 1 to move in the second direction to shorten the door stop.

[0042] The preset angle of the paddle 7 rotating counterclockwise is 90°.

[0043] like Figures 1 to 5 As shown, an arc is set in the direction from the notch of the limit groove 9 to the bottom of the groove. When the top block 11 is inserted into the bottom of the limit groove 9, the top block 11 can be positioned at the bottom of the limit groove 9 to prevent the top block 11 from automatically resetting, making it convenient for the user to push a partition piece 1 to move in the second direction.

[0044] like Figures 1 to 3As shown, the connecting component includes a first connecting rod 12 and a connecting plate 13. A partition plate 1 is connected to one end of the first connecting rod 12. The other partition plate 1 is provided with a first slide groove 14. The other end of the first connecting rod 12 passes through the first slide groove 14 and is connected to the connecting plate 13. The connecting plate 13 is slidably connected in the first slide groove 14 so that one partition plate 1 can be slidably connected to the other partition plate 1.

[0045] like Figure 1 As shown, a cushion block 17 is provided on one side of the partition plate 1 close to the door frame to prevent the partition plate 1 from directly contacting and colliding with the door opening or the aisle. Example 2

[0046] like Figures 1 to 3 As shown, the difference from Example 1 is that the retractable door stop disclosed in this embodiment has a second slide groove 15 on the surface of one partition piece 1, and the second slide groove 15 is placed between the racks 2. A second connecting rod 16 is provided on the surface of the other partition piece 1, and one end of the second connecting rod 16 is slidably connected to the second slide groove 15 to ensure the tightness of the connection between the middle parts of the two partition pieces 1, prevent the gear 4 from detaching from the rack 2, and improve the stability of the door stop when used.

[0047] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
