Description

Technical Field

[0001] This utility model relates to the field of grass combing machine technology, and in particular to a folding handle structure and a grass combing machine using the same. Background Technology

[0002] During the growth of a lawn, some of the grass blades at the bottom will be covered by other grass blades and will not participate in photosynthesis, which can easily lead to the entire lawn withering or even mold and rot. The blades of a lawnmower can effectively remove the dead grass layer, enhance the lawn's disease resistance, appropriately reduce lawn density, improve lawn aeration, and promote healthy lawn growth.

[0003] To facilitate the use of grass combers, most current grass combers are hand-push type. For example, Chinese patent "CN211656813U" discloses "a type of grass comber that loosens soil." The operating handle of this grass comber also includes intermediate components that are detachably connected to the front and rear components. By adding detachable intermediate components to the front and rear components, operating handles of different heights can be made to meet the needs of operators of different heights. Although the operating handle is composed of detachable segments, when the grass comber is not in use and is parked, each component needs to be disassembled one by one to reduce the area occupied by the grass comber. When the grass comber is in use, each component needs to be reassembled, which prolongs the cleaning time before and after the grass comber is in operation and reduces efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a folding handle structure and a grass comber using it. It solves the problem that in the existing technology, when the grass comber is parked, each component needs to be disassembled one by one to reduce the area occupied by the grass comber. When using the grass comber, each component needs to be installed. This prolongs the cleaning time before and after the grass comber is used and reduces efficiency.

[0005] On the one hand, according to the embodiments of this utility model, the present utility model adopts the following technical solution:

[0006] The folding handle structure, connected to the housing, includes:

[0007] A handle frame, which includes several connecting frames connected end to end in sequence;

[0008] The locking unit includes a mounting shaft passing through two adjacent connecting frames and a locking member disposed on the mounting shaft. The locking member abuts between the two adjacent connecting frames to fix the relative position of the two adjacent connecting frames.

[0009] An adjustment unit, located in the housing and connected to the first connecting frame, is used to adjust the angle between the handle bracket and the housing.

[0010] Preferably, the locking unit includes:

[0014] Preferably, a limiting block is provided at the end of the mounting shaft away from the first adjusting block. The limiting block extends along the axis of the mounting shaft to form a square block. The connecting bracket has a square hole, and the square block is engaged with the square hole.

[0015] Preferably, the extrusion plate has an arc-shaped structure, and the inner arc-shaped surface is attached to the outer side of the connecting frame.

[0016] Preferably, the adjustment unit includes:

[0017] Two limiting rings, one of which is connected to the first connecting frame and the other is located in the housing. Both limiting rings are provided with limiting teeth, and the two limiting teeth mesh with each other.

[0024] On the other hand, according to the embodiments of this utility model, the present utility model adopts the following technical solution:

[0025] A grass comber, including a folding handle design.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The handle frame of the grass comber is composed of several connecting frames. Under the action of the locking unit, the two adjacent connecting frames can be locked together. When the locking unit releases the fixation of the two adjacent connecting frames, the two adjacent connecting frames can be folded, reducing the overall space occupied by the equipment and facilitating transportation and storage. When each connecting frame is unfolded, the two adjacent connecting frames can be fixed and limited by the locking device for operation. The operator can unfold or fold the handle frame without the use of tools by using the locking device, eliminating the tedious process of disassembling and assembling each section of the traditional detachable handle.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0035] In existing technologies (such as CN211656813U), the handle mechanism of a grass comber often adopts a segmented splicing structure. When the grass comber is not in use, it is necessary to frequently turn the screws to disassemble the various parts of the handle structure in order to reduce the space occupied by the entire device. When it is used again, it is necessary to assemble each part one by one and tighten the screws to secure the connection, which is quite wasteful of preparation and storage time before and after using the grass comber.

[0036] like Figures 1 to 3 As shown, this embodiment of the utility model proposes a folding handle structure, connected to the housing 2, including:

[0037] A handle frame, comprising several connecting frames 1 connected end to end in sequence;

[0038] The locking unit includes a mounting shaft 6 passing through two adjacent connecting frames 1 and a locking member disposed on the mounting shaft 6. The locking member abuts against the two adjacent connecting frames 1 to fix the relative position of the two adjacent connecting frames 1.

[0039] An adjustment unit is located in the housing 2 and connected to the first connecting frame 1, and is used to adjust the angle between the handle frame and the housing 2.

[0040] In the embodiments of this utility model, each connecting frame 1 is spliced ​​together one by one along its axial direction. For ease of use, three connecting frames 1 are preferably used. The connecting frame 1 connected to the housing 2 is the first connecting frame 1, and the farthest connecting frame 1 is the tail connecting frame 1. All three connecting frames 1 can adopt a U-shaped frame structure. In order to more compactly store the handle structure at the top of the housing 2, such as Figure 1 As shown, the first connecting frame 1 can cut off the middle section of the U-shaped frame structure, forming a two-section tubular structure. At the same time, the locking unit is connected to one of the two adjacent connecting frames 1, used to fasten or release the connection between the two adjacent connecting frames 1. When three connecting frames 1 are used, preferably, two locking units are installed at the end of the tail connecting frame 1 and the end of the first connecting frame 1, respectively, to connect the two ends of the middle connecting frame 1.

[0041] Under the action of the locking unit, two adjacent connecting frames 1 can be rotatably connected via the mounting shaft 6, allowing the two connecting frames 1 to rotate around the mounting shaft 6 as the axis, thereby changing the angle between the two connecting frames 1. When the combing machine is in use, the two connecting frames 1 are in a horizontal state, that is, 180°. Figure 2As shown, when folded, the two connecting frames 1 form an acute angle of 15°. Simultaneously, with the cooperation of the locking mechanism, after two adjacent connecting frames 1 are folded, they can be fixed by the locking mechanism. The folded handle structure is generally "Z" shaped, effectively reducing the overall space occupied by the equipment and facilitating transportation and storage. When each connecting frame 1 is unfolded, the locking mechanism can fix and limit the movement of two adjacent connecting frames 1 for operation. Throughout the process, the operator can unfold or fold the handle structure using the locking mechanism without the need for tools, eliminating the tedious process of disassembling and assembling sections of the traditional detachable handle. This significantly shortens the preparation and storage time before and after using the comb, and also avoids the problem of lost or confused parts after disassembly. The aforementioned locking mechanism can be a threaded structure installed on the mounting shaft 6.

[0042] Based on the above scheme, the structure of the locking unit is optimized, such as... Figure 3 and Figure 5 As shown, the locking unit includes:

[0043] An extrusion plate 5 is disposed at the end of the connecting frame 1 and abuts against the outer side of the adjacent connecting frame 1, and a mounting shaft 6 passes through the extrusion plate 5 and the adjacent connecting frame 1.

[0044] The first adjusting block 7 is rotatably disposed at the end of the mounting shaft 6, and the first adjusting block 7 extends along the first direction to form a first eccentric pressing part 701;

[0045] The first flexible member 602 is sleeved on the mounting shaft 6 and located between the first adjusting block 7 and the extrusion plate 5, and the first eccentric extrusion part 701 abuts against the first flexible member 602.

[0046] The overall length of the mounting shaft 6 remains unchanged in the initial state, i.e. Figure 5 As shown, when the extrusion plate 5 and connecting frame 1 are not compressed, the first eccentric extrusion part 701 does not abut against the first flexible member 602. The extrusion plate 5, connecting frame 1, and first flexible member 602 can all move on the mounting shaft 6, allowing sufficient clearance on the mounting shaft 6 for the extrusion plate 5 and connecting frame 1 to separate, thus enabling the extrusion plate 5 and connecting frame 1 to be folded. When the handle structure is unfolded for use, when two adjacent connecting frames 1 are adjusted to have collinear axes, rotating the first adjusting block 7 causes the first eccentric extrusion part 701 formed by the first adjusting block 7 to rotate around the rotation connection point of the first adjusting block 7. This causes the first eccentric extrusion part 701 to compress the first flexible member 602 and occupy the clearance on the mounting shaft 6, thereby causing the extrusion plate 5 and connecting frame 1 to abut against each other, thus fixing the two connecting frames 1 together. The first flexible member 602 can be an elastic structure, such as highly elastic rubber, or a rigid elastic sheet, such as a hollow elastic sheet.

[0047] Specifically, such as Figure 3 As shown, a limiting block 601 is provided at the end of the mounting shaft 6 away from the first adjusting block 7. The limiting block 601 extends along the axis of the mounting shaft 6 to form a square block 604. The connecting frame 1 has a square hole 102. The square block 604 is engaged with the square hole 102. Through the cooperation of the square block 604 and the square hole 102, the locking element can be limited on the connecting frame 1 to prevent it from rotating, which facilitates subsequent adjustments.

[0048] Meanwhile, the extrusion plate 5 has an arc-shaped structure, and its inner arc-shaped surface is attached to the outer side of the connecting frame 1. The connecting frame 1 adopts a tubular structure, which is inexpensive and easy to process. The extrusion plate 5 with an arc-shaped structure increases its contact area when it abuts against the connecting frame 1, ensuring the structural stability of the handle structure after it is unfolded.

[0049] Based on the above scheme, the structure of the adjustment unit is optimized, such as... Figure 4 As shown, the adjustment unit includes:

[0050] Two limiting rings 4, one of which is connected to the first connecting frame 1, and the other limiting ring 4 is located in the housing 2. Both limiting rings 4 are provided with limiting tooth surfaces 401, and the two limiting tooth surfaces 401 mesh with each other.

[0051] The second adjusting block 9 is rotatably provided with a mounting pin 8. The mounting pin 8 passes through the first connecting frame 1 and two limiting rings 4 and is connected to the housing 2. The second adjusting block 9 extends along the first direction to form a second eccentric extrusion part 901.

[0052] The second flexible member 801 is sleeved on the mounting pin 8 and positioned between the second adjusting block 9 and the first connecting frame 1, and the second eccentric pressing part 901 abuts against the second flexible member 801.

[0053] The tail section connecting bracket 1 is generally the part held by the operator. The height of the tail section connecting bracket 1 usually changes depending on the operator's height. Figure 1 or Figure 2 For example, the right limiting ring 4 is fixedly mounted on the housing 2, and the left limiting ring 4 is installed on the first connecting frame 1. When the height of the tail connecting frame 1 is adjusted, the following applies: Figure 4For example, by rotating the second adjusting block 9, the second adjusting block 9 drives the second eccentric pressing part 901 to rotate counterclockwise, thereby releasing the second eccentric pressing part 901 from pressing the second flexible part 801. This allows the second flexible part 801 and the left limiting ring 4 to move to the left on the mounting pin 8, thereby separating the limiting tooth surface 401 of the left limiting ring 4 from the limiting tooth surface 401 of the right limiting ring 4. This releases the limitation on the entire handle structure. The mounting pin 8 is rotatably mounted on the housing 2, allowing the entire handle structure to rotate around the mounting pin 8 as the axis, thereby changing the overall... The angle between the handle structure and the housing 2 changes the height of the tail section connecting frame 1, making it convenient for different users. Furthermore, during storage, to further reduce the overall footprint, the handle structure can be moved closer to the housing 2 to minimize space usage and facilitate storage. After the height of the tail section connecting frame 1 is adjusted, the second adjusting block 9 is rotated in the opposite direction, causing the second eccentric pressing part 901 to press against the second flexible part 801. This causes the two limiting rings 4 to re-engage through the limiting tooth surface 401, completing the fixation. The second flexible part 801 can be an elastic structure, such as highly elastic rubber, or a rigid elastic sheet, such as a hollow elastic sheet.

[0054] Specifically, such as Figure 4 As shown, one of the limiting rings 4 is provided with a connecting sleeve 3, and the first connecting frame 1 passes through the connecting sleeve 3. Under the action of the connecting sleeve 3, it is convenient to quickly connect the handle structure and the housing 2.

[0055] Specifically, such as Figure 5 As shown, both the first adjusting block 7 and the second adjusting block 9 extend along the second direction to form an adjusting part 702. The second direction is perpendicular to the first direction, which increases the manual adjustment part of the first adjusting block 7 and the second adjusting block 9, making it convenient for the operator to adjust and use.

[0056] Meanwhile, both the second flexible component 801 and the first flexible component 602 are provided with an arc-shaped limiting layer 603, which increases the contact area between the second flexible component 801, the first flexible component 602 and the extrusion plate 5 and the first connecting frame 1, ensuring the stability of the fastening.

[0057] Specifically, such as Figure 1 As shown, the tail section connecting frame 1 is equipped with an anti-slip sleeve 101, which increases the friction between the operator's palm and the tail section connecting frame 1, making it convenient to use.

[0058] like Figure 1 As shown in the figure, this utility model embodiment also proposes a grass comber, including the above-mentioned folding handle structure. The specific structure of the folding handle structure is as described in the above embodiment. Since this grass comber adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought about by the technical solutions of the above embodiment, which will not be described in detail here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
