DETAILED DESCRIPTION

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] Embodiment 1

[0028] like Figure 1-Figure 4 As shown, a foldable garden rake proposed by the utility model comprises a connecting frame 1, a rotating assembly and a synchronous driving mechanism. The connecting frame 1 is arranged in an arc-shaped structure, and a mounting groove 2 is provided on the outer side thereof. A plurality of groups of spike rakes 3 are evenly connected in the mounting groove 2. The spike rakes 3 on both sides of the connecting frame are provided with rotating assemblies, which have a folding position and an unfolding position. In the folding position, the garden rake is in a convergent state, and in the unfolding position, the garden rake is in an unfolding state. A synchronous driving mechanism for driving the plurality of groups of spike rakes 3 to switch from the folding position to the unfolding position is further provided in the mounting groove 2, and the synchronous driving mechanism has a limiting member for limiting the rotating assembly.

[0029] like Figure 2 As shown, the rotating assembly includes a rotating shaft 6 and a connecting ring 7. Both ends of the rotating shaft 6 are rotatably connected to the mounting groove 2 through bearings. The rotating shaft 6 is connected to the connecting ring 7, and the connecting ring 7 is connected to one end of the spike rake 3.

[0030] The rotating shaft 6 connected to the spike rake 3 located in the middle is fixedly arranged with the groove wall of the mounting groove 2. During use, it is in a fixed state and will not be affected by the synchronous driving mechanism.

[0031] like Figure 2 As shown, the synchronous drive mechanism includes gears 8, arc plates 9 and guide members. There are multiple groups of gears 8, which are respectively installed on the rotating shaft 6. There are two groups of arc plates 9, which are respectively located on both sides of the mounting groove 2. The outer side of the arc plate 9 is provided with a row of teeth 10 that mesh synchronously with the multiple groups of gears 8. The arc plate 9 is also provided with a guide member for guiding its movement.

[0032] like Figure 2As shown, the guide member includes a guide block 12 and a guide column 14. A guide groove 11 communicating with the mounting groove 2 is provided on the connecting frame 1. The guide block 12 is slidably arranged in the guide groove 11. A through hole 13 is provided on the guide block 12. A guide column 14 is penetrated through the through hole 13. Both ends of the guide column 14 are connected to the groove wall of the guide groove 11. By utilizing the action of the guide column 14 and the guide block 12, when a force is applied to the arc plate 9, it will move along the direction of the guide groove 11 and the guide column 14, ensuring that the row of teeth 10 on the arc plate 9 is always engaged with the multiple sets of gears 8 to prevent it from being out of the engagement range.

[0033] like Figure 1 As shown, a handle 4 is provided on the side of the connecting frame 1, and a flexible pad 5 is provided on the handle 4 for preventing the hand from slipping.

[0034] Embodiment 2

[0035] like Figure 1-Figure 4 As shown, the foldable garden rake proposed by the utility model, based on the above embodiment, this embodiment also records in detail the specific components of the limiting member and the specific connection method between the limiting member and the guide member.

[0036] like Figure 4 As shown, the limiting member includes a connecting block 15, a tension spring 16, a slide plate 17 and a clamping column 18. The connecting block 15 is connected to the guide block 12, and a slide groove 19 is provided on the connecting block 15. A tension spring 16 is arranged in the slide groove 19. One end of the tension spring 16 is connected to the slide plate 17. The slide plate 17 is slidably connected to the slide groove 19. The slide plate 17 is connected to a clamping column 18 that passes through the slide groove 19.

[0037] like Figure 3 As shown, the connecting frame 1 is provided with corresponding openings 20 for engaging with the engaging posts 18 , and four groups of openings 20 are provided for engaging with the engaging posts 18 in different states of the gardening rake.

[0038] In summary, when the utility model is in use, when it is necessary to switch the working area of ​​the garden rake, that is, it is necessary to adjust the rotation angle of the spike rake 3, firstly, manually apply an outward force to the clamping column 18, the top end of the clamping column 18 is separated from the bayonet 20, and the bottom end of the clamping column 18 pulls the tension spring 16 through the slide plate 17, so that the tension spring 16 is elastically deformed, and then the connecting block 15 is pulled along the direction of the guide groove 11, so that the connecting block 15 drives the arc plate 9 to move along the set trajectory of the guide column 14 through the guide block 12. During the movement, the row of teeth 10 on its side is meshed with the gear 8, and the meshing force drives the spike rake 3 to adjust the angle through the rotating shaft 6 until it moves to the clamping column 18 and is aligned with the other bayonet 20. At this time, the external pulling force applied to the clamping column 18 is released, and under the action of the restoring force of the tension spring 16, the slide plate 17 drives the clamping column 18 to reset and re-engage with the corresponding bayonet 20. The overall adjustment method is simple and has strong operability.

[0039] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
