Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grass combing machines, specifically relating to a flip-top structure with quick disassembly and assembly function and a grass combing machine. Background Technology
[0002] In landscaping, lawn combs are now widely used to remove dead grass and maintain the healthy growth of lawns.
[0003] Currently, the mainstream flip-top connection methods on hay combers mainly include screw fastening structures and hinge + knob lock / slide lock structures. Among them, the screw fastening structure mainly uses multiple screws to fix the flip-top to the main body. However, its biggest drawback is that each disassembly and assembly requires the use of special tools such as screwdrivers, making the operation cumbersome and time-consuming, especially in scenarios that require frequent maintenance or quick on-site replacement. The hinge + knob lock / slide lock structure has a hinge on one side of the flip-top for rotation and a manual locking device on the other side. However, due to its complex assembly process and high manufacturing cost, it does not meet the needs of mass production assembly. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a flip-top structure and a combing machine with quick disassembly and assembly functions that are simple in structure, have good stability, and extremely high disassembly and assembly efficiency.
[0005] The objective of this utility model can be achieved by addressing the following technical problem: proposing a flip-top structure with quick assembly and disassembly function, comprising a mounting frame and a flip-top cover, wherein the flip-top cover is movably connected to the mounting frame, wherein:
[0006] The inner wall of the mounting frame is provided with a connecting pin and an elastic element. The elastic element is installed on the connecting pin, and one end of the elastic element is connected to the inner wall of the mounting frame.
[0007] The inner wall of the flip cover is provided with a connecting arm that extends outward therefrom, and the end of the connecting arm is formed with a snap-fit part;
[0008] The latching part can be movably engaged with the connecting pin when the connecting arm passes through the mounting frame, and is connected to the connecting arm via the end of the elastic element away from the inner wall of the mounting frame.
[0009] In the aforementioned flip cover structure with quick assembly and disassembly function, the end of the connecting arm is formed with a first limiting block and a second limiting block. The first limiting block and the second limiting block are spaced apart, and a connecting block is provided between them to form a buckle portion for engaging with the connecting pin.
[0010] In the aforementioned flip-top structure with quick disassembly and assembly function, the flip-top is made of a transparent material.
[0011] In the aforementioned flip cover structure with quick disassembly and assembly function, both the first limiting block and the second limiting block have inner grooves, and the inner grooves are connected to the buckle portion.
[0012] In the aforementioned flip-top structure with quick assembly and disassembly function, a curved portion is also formed between the connecting arm and the second limiting block.
[0013] In the aforementioned flip-top structure with quick assembly and disassembly function, the side wall of the second limiting block is also provided with a through hole, and the end of the elastic element away from the inner wall of the mounting frame is connected in the through hole.
[0014] In the aforementioned flip cover structure with quick assembly and disassembly function, the mounting frame is further provided with interconnected mounting holes and extension holes. The overall length direction of the mounting holes and the extension holes is consistent with the rotation direction of the flip cover, so that the connecting arm can pass through the mounting holes and extend into the extension holes.
[0015] In the aforementioned flip-top structure with quick assembly and disassembly function, the inner wall of the mounting frame is further provided with a first stop and a second stop, which are spaced apart. The first stop and the second stop together form a locking groove, and the end of the elastic member extends into the locking groove.
[0016] In the aforementioned flip-top structure with quick assembly and disassembly function, the inner wall of the mounting frame further includes an anti-detachment plate and symmetrically arranged support plates and limiting plates. The support plate has a support groove, and the limiting plate has a limiting groove. The opening directions of the support groove and the limiting groove are opposite. The anti-detachment plate is provided on the side wall of any one of the limiting plates to prevent the connecting pin from disengaging from the support groove and the limiting groove.
[0017] The technical solution adopted by this utility model to solve its technical problem is to also propose a grass combing machine, including a flip-top structure with quick disassembly and assembly function as described above.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] (1) The present invention provides a flip cover structure and a combing machine with quick assembly and disassembly function. By setting connecting pins and elastic elements on the mounting frame and setting connecting arms with buckle parts on the flip cover, the flip cover can be installed by simply aligning the buckle parts and inserting them into the mounting frame, and locking the flip cover with the help of the elastic elements. That is, the elastic elements can simultaneously limit and rotate the flip cover, improving the stability and safety of the connection. No tools or additional fasteners are required, ensuring assembly and disassembly efficiency.
[0020] (2) When the flip cover is subjected to external impact during installation or use, the bending part can absorb some of the stress and prevent the connecting arm from breaking or plastically deforming due to excessive rigidity.
[0021] (3) The extension direction of the mounting hole and the extension hole is consistent with the rotation direction of the flip cover, so that the connecting arm can move smoothly along the channel during the flipping process, avoiding jamming or interference problems. At the same time, it provides guiding space for the displacement of the flip cover during the flipping process, ensuring smooth flipping action. Attached Figure Description

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0030] like Figure 1 As shown in the figure, this solution mainly describes a flip-top structure with quick disassembly and assembly function on a hay comber. However, this flip-top structure with quick disassembly and assembly function is not limited to hay combers, but can also be applied to other equipment that requires the installation of flip-top covers.
[0031] like Figures 1 to 4 As shown, a flip cover structure with quick assembly and disassembly function includes a mounting frame 1 and a flip cover 2. The flip cover 2 is movably connected to the mounting frame 1. The inner wall of the mounting frame 1 is provided with a connecting pin 10 and an elastic element 11. The elastic element 11 is mounted on the connecting pin 10, and one end of the elastic element 11 is connected to the inner wall of the mounting frame 1. The inner wall of the flip cover 2 is provided with a connecting arm 20 extending outward. The end of the connecting arm 20 forms a latching part 204. The latching part 204 can be movably latched onto the connecting pin 10 when the connecting arm 20 passes through the mounting frame 1, and is connected to the connecting arm 20 via the end of the elastic element 11 away from the inner wall of the mounting frame 1.
[0032] like Figures 1 to 4 As shown, before the assembly operation begins, the worker can pre-assemble the elastic element 11 onto the connecting pin 10. With the connecting pin 10 fixed to the inner wall of the mounting frame 1, one end of the elastic element 11 can be pre-connected to the mounting frame 1. Then, after the flip cover 2 is aligned with the mounting frame 1, the connecting arm 20 on the flip cover 2 can be passed through the mounting frame 1 (see reference). Figure 2 (Extending from one side wall where the flip cover 2 is located to the other side wall of the mounting frame 1), as the latching part 204 on the connecting arm 20 engages with the connecting pin 10, the end of the elastic element 11 away from the mounting frame 1 can be connected to the connecting arm 20, thereby realizing the rotational connection between the flip cover 2 and the mounting frame 1. It can be seen that the elastic element 11 provides elastic preload to the connecting arm 20, so that the latching part 204 is stably locked on the connecting pin 10, and the installation can be completed without additional screws or tools, simplifying the assembly process and significantly improving the disassembly and assembly efficiency; at the same time, relying on the elastic deformation function of the elastic element 11, it provides a rotational reset function when the flip cover 2 rotates relative to the mounting frame 1, thereby improving the stability and safety of the connection.
[0033] The end of the connecting arm 20 is provided with a first limiting block 200 and a second limiting block 201. The first limiting block 200 and the second limiting block 201 are spaced apart, and a connecting block 203 is provided between them to form a snap-fit portion 204 for engaging with the connecting pin 10.
[0034] like Figure 2 and Figure 3As shown, this embodiment forms a stable U-shaped slot structure by setting a buckle structure consisting of a first limiting block 200, a second limiting block 201, and a connecting block 203 at the end of the connecting arm 20. This structure can more accurately and firmly engage with the connecting pin 10. This structure enhances the stability of the engagement between the buckle part 204 and the connecting pin 10, prevents accidental disengagement due to vibration or external force, improves the reliability and safety of the flip cover structure, and facilitates quick release by pressing the limiting block during disassembly, thus balancing the convenience of installation and the safety of use.
[0035] Preferably, in this embodiment, the flip cover 2 is made of transparent material, allowing users to observe the internal operating status or component working conditions of the equipment without opening the cover, such as the operation of the brush comb blades or dust accumulation, thus improving the visibility and ease of use of the equipment. At the same time, this design helps to promptly identify faults or maintenance needs, reduces unnecessary frequent opening of the cover, and extends the service life of the structure, making it particularly suitable for electromechanical equipment that requires regular inspection but not frequent maintenance.
[0036] Both the first limiting block 200 and the second limiting block 201 have an inner groove 202a, which is connected to the buckle part 204.
[0037] like Figure 3 As shown, in this embodiment, an inner groove 202a communicating with the latching part 204 is provided inside the first limiting block 200 and the second limiting block 201. On the one hand, this can reduce the overall weight of the connecting arm 20 and reduce material costs; on the other hand, the inner groove 202a structure enhances the elastic deformation capability of the limiting block, allowing the latching part 204 to undergo moderate elastic expansion during the latching process, which facilitates the smooth insertion of the connecting pin 10 and reduces assembly resistance; at the same time, during disassembly, the first / second limiting block 201 can be contracted by squeezing the inner groove 202a, thereby quickly releasing the latch lock, further improving the smoothness of disassembly and assembly and the user experience.
[0038] The side wall of the second limiting block 201 is also provided with a through hole 201a, and the end of the elastic element 11 away from the inner wall of the mounting frame 1 is connected in the through hole 201a.
[0039] like Figure 2 and Figure 3 As shown, with the snap-fit part 204 engaging with the connecting pin 10, the free end of the elastic element 11 (i.e., the end of the elastic element 11 away from the mounting frame 1) is fixed in the through hole 201a on the side wall of the second limiting block 201, realizing direct linkage between the elastic element 11 and the connecting arm 20. The elastic element 11 is preferably a torsion spring structure, which can both realize the rotational connection between the flip cover 2 and the mounting frame 1 and provide rotational support force for the rotational operation of the flip cover 2, achieving the effect of "one component, two functions" and improving the reliability of the overall structure.
[0040] Preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, a bending portion 205 is provided between the connecting arm 20 and the second limiting block 201, which increases the flexibility and buffering performance of this part. When the flip cover 2 is subjected to external force impact during installation or use, the bending portion 205 can absorb some stress and prevent the connecting arm 20 from breaking or plastically deforming due to excessive rigidity.
[0041] The mounting frame 1 is also provided with an interconnected mounting hole 12 and an extension hole 13. The overall length direction of the mounting hole 12 and the extension hole 13 is consistent with the rotation direction of the flip cover 2, so that the connecting arm 20 can pass through the mounting hole 12 and extend into the extension hole 13.
[0042] like Figure 3 and Figure 4 As shown, during installation, the latching part 204 can be latched onto the connecting pin 10 by passing the connecting arm 20 through the mounting hole 12. Furthermore, because this embodiment adds an extension hole 13 that communicates with the mounting hole 12, it helps guide the latching part 204 to slide smoothly into the position of the connecting pin 10, improving the assembly error tolerance and structural durability. In addition, the extension hole 13 provides a guiding and limiting function for the connecting arm 20 when the flip cover 2 rotates relative to the mounting frame 1, ensuring that the flip cover 2 can be accurately latched and sealed on the mounting frame 1, avoiding the phenomenon of jamming between the flip cover 2 and the mounting frame 1 due to displacement during the rotation of the flip cover 2, thus extending the service life of the overall structure.
[0043] Preferably, such as Figure 3 As shown, this embodiment also provides a stepped groove on the inner wall of the periphery of the flip cover 2. The stepped groove can help the flip cover 2 and the mounting frame 1 to be accurately aligned and sealed, ensuring the tightness of the fit between the two. Of course, in this embodiment, the fastening between the flip cover 2 and the mounting frame 1 can also adopt a magnetic structure (not shown in the figure) to further enhance the overall stability and reliability of the structure.
[0044] The inner wall of the mounting frame 1 is also formed with a first stop 14 and a second stop 15 spaced apart. The first stop 14 and the second stop 15 together form a locking groove 160, and the end of the elastic member 11 extends into the locking groove 160.
[0045] like Figure 4As shown, the locking groove 160 formed by the first stop 14 and the second stop 15 is used to limit the free end of the elastic element 11, preventing it from shifting or coming out during operation, and ensuring that the elastic element 11 is always in the correct pre-tightened position. This ensures a stable locking force between the other end of the elastic element 11 and the buckle 204. This structure improves the reliability of the installation of the elastic element 11, avoids locking failure caused by the loosening of the elastic element 11, and enhances the durability and safety of the overall structure. It is especially suitable for equipment in environments with strong vibration.
[0046] The inner wall of the mounting frame 1 also includes an anti-detachment plate 17 and symmetrically arranged support plates 18 and limiting plates 19. The support plate 18 has a support groove 180, and the limiting plate 19 has a limiting groove 190. The opening directions of the support groove 180 and the limiting groove 190 are opposite. The anti-detachment plate 17 is provided on the side wall of any one of the limiting plates 19 to prevent the connecting pin 10 from disengaging from the support groove 180 and the limiting groove 190.
[0047] like Figure 4 As shown, in this embodiment, the support plate 18 and the limiting plate 19 are symmetrically arranged, and the connecting pin 10 is dually positioned by the support groove 180 and the limiting groove 190 with opposite directions, which effectively prevents the connecting pin 10 from radially displacing during use (radial movement is limited by tightening screws at the end of the connecting pin 10 in conjunction with the anti-detachment plate 17, not shown in the figure); the setting of the anti-detachment plate 17 further limits the possibility of the connecting pin 10 coming out of the groove, which greatly improves the stability of the connecting pin 10 installation; this multi-limiting structure significantly enhances the structural strength and reliability of the mounting frame 1, avoids the failure of the entire buckling mechanism due to the loosening of the connecting pin 10, and ensures the safety and stability of the flip structure for long-term use.
