Technical Field
[0001] The utility model relates to the technical field of lawn mower components, in particular to a wire body protection structure of a lawn mower. Background Art
[0002] A lawn mower is also called a weed cutter, lawn mower, lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It consists of a cutter disc, an engine, running wheels, a walking mechanism, a blade, an armrest, and a control part.
[0003] With the development of lawn mowers, a type of string mower has emerged, which uses a high-speed rotating wire to replace the original blade to cut the grass. Since the cutting medium used is a wire, it will not have the problem of entanglement, but it also has the problem of being unable to cut harder materials, that is, its scope of use is limited.
[0004] For string mowers, there is a problem that the installed string body may fall out, which makes the string body unable to provide stable cutting or directly causes irreparable damage to the string body. For this reason, we propose a string body protection structure for the mower. Utility Model Content

[0007] By adopting the above technical solution, the wire body can be protected by limiting the position and locking, thereby preventing the wire body from escaping from the cavity and effectively preventing the wire body from being damaged.
[0008] The present invention is further configured such that the limiting structure can be a protrusion fixedly arranged on the inner wall of the cavity, and there are two groups of protrusions, and the two groups of protrusions are symmetrically distributed on the inner wall of the cavity.
[0009] By adopting the above technical solution, a driving effect on the line body is achieved.
[0010] The present invention is further configured such that the limiting structure can also be a limiting plate installed on the outer wall of the protrusion, and there are two groups of limiting plates which are correspondingly installed on each group of the outer wall of the protrusion, and each group of the limiting plates is connected to the outer wall of the protrusion through a torsion spring shaft.
[0011] By adopting the above technical solution, a limiting effect on the line body is achieved.
[0012] The utility model is further configured such that a slider which is limitedly slidably connected to the inside of the installation card is fixedly connected to the outer side of the protrusion, and a screw rod which is adapted to the slider is provided on the inner side of the slider.
[0013] By adopting the above technical solution, the slider is driven.
[0014] The present invention is further configured such that the end of the screw rod is fixedly connected to a first bevel gear, and one side of the first bevel gear is fixedly connected to a second bevel gear meshing with the first bevel gear.
[0015] By adopting the above technical solution, a driving effect on the screw rod is achieved.
[0016] The present invention is further configured such that a rotating shaft is fixedly connected to an outer wall of one side of the second bevel gear, and a thumbwheel extending to the outside of the mounting card is fixedly sleeved on the outer wall of the rotating shaft.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0027] The following describes an embodiment of the present invention based on its overall structure.
[0028] Example 1
[0029] A wire protection structure for a lawn mower, such as Figure 1-2 As shown, it includes a rotating disk 1, with mounting parts 2 provided on both sides of the rotating disk 1, and mounting cards 3 installed inside the mounting parts 2, and a cavity 4 is opened inside the mounting cards 3.
[0030] See also Figure 2 , bumps 5 are fixedly provided on the inner wall of the cavity 2 , there are two groups of bumps 5 , and the two groups of bumps 5 are symmetrically distributed on the inner wall of the cavity 4 .
[0031] Example 2
[0032] like Figure 3-4 FIG. 1 is a second embodiment of the present invention, wherein the figure shows a replacement scheme for the bump 5 in the first embodiment;
[0033] For details, please refer to Figure 3-4 A limit plate 6 is installed on the outer wall of the protrusion 5, and there are two groups of limit plates 6 and they are correspondingly installed on the outer wall of each group of protrusions 5. Each group of limit plates 6 is connected to the outer wall of the protrusion 5 through a torsion spring shaft. The outer side of the protrusion 5 is fixedly connected with a slider 7 that is slidingly connected to the internal limit of the mounting card 3, and the inner side of the slider 7 is provided with a screw rod 8 adapted to the slider 7. The end of the screw rod 8 is fixedly connected with a first bevel gear 9, and one side of the first bevel gear 9 is fixedly connected with a second bevel gear 10 that is meshed with the first bevel gear 9. The outer wall of one side of the second bevel gear 10 is fixedly connected with a rotating shaft 11, and the outer wall of the rotating shaft 11 is fixedly sleeved with a dial wheel 12 extending to the outside of the mounting card 3.
[0034] The working principle of the present invention is as follows: when installing the wire body, the wire body is inserted into the installation card 3, and the limiting structure is used to clamp and limit the wire body, thereby ensuring that the wire body is fixed and protected.
[0035] The working principle of the first embodiment of the present invention is as follows: the wire body is clamped into the cavity 4, and the convex block 5 is used to prevent the wire body from escaping from the cavity, thereby playing a role in limiting and protecting the wire body.
[0036] The working principle of the second embodiment of the present utility model is as follows: after the wire body is inserted into the cavity 4, the dial wheel 12 is dialed, so that the dial wheel 12 drives the rotating shaft 11 to rotate, and then the rotating shaft 11 drives the second bevel gear 10 to rotate, thereby driving the first bevel gear 9. After the first bevel gear 9 rotates, it drives the screw rod 8 to rotate, thereby moving the slider 7 located on the outer wall of the screw rod 8. The movement of the slider 7 drives the protrusion 5 to move, so that the limiting plate 6 can further limit the wire body, thereby improving the quality of the limit, that is, the quality of protection.
