Description

Technical Field

[0001] This utility model belongs to the field of single-side lifting of lawnmowers, and specifically relates to a single-side lifting device for lawnmowers. Background Technology

[0002] Currently, lawnmowers are also known as lawn trimmers, lawn mowers, and lawn mowers. A lawnmower is a mechanical tool used for trimming lawns, vegetation, etc. It consists of a blade disc, engine, wheels, walking mechanism, blades, handle, and control unit. For example, in the small lawnmower shown in the design patent CN202130184413.0, a large amount of mud and grass clippings inevitably adhere to its walking wheels and other parts during use. The mud adhesion affects the normal movement of the lawnmower, so a corresponding lifting device is needed to lift the lawnmower on one side for subsequent cleaning.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a single-side lifting device for lawnmowers to solve the problem that when existing small lawnmowers are in use, a large amount of mud and grass clippings inevitably adhere to their driving wheels and other parts. The mud adhesion affects the normal movement of the lawnmower, so a corresponding lifting device is needed to lift the lawnmower on one side for subsequent cleaning. Utility Model Content

[0004] This utility model proposes a single-sided lifting device for lawnmowers, which solves the problem that in the prior art, small lawnmowers inevitably accumulate a large amount of mud and grass clippings on their wheels and other parts during use. The mud and grass clippings affect the normal movement of the lawnmower, so a corresponding lifting device is needed to lift the lawnmower on one side for easy cleaning later.

[0005] The technical solution of this utility model is implemented as follows: A single-sided lifting device for a lawnmower includes a connecting rod, wherein a first sleeve is fixedly connected to the center position of the right end face of the connecting rod. The first sleeve has an internal hollow structure, and a first extension tube is inserted into the inside of the first sleeve. A branch tube is fixedly connected to the side of the first extension tube away from the first sleeve, and the structure of the branch tube is consistent with the structure of the connecting rod.

[0006] In one preferred embodiment, a fixing pin is installed between the first sleeve and the first extension tube, and a second sleeve is hinged to the right side of the connecting rod. The second sleeve has two locations.

[0007] In a preferred embodiment, the top ends of the two second sleeves are also hinged with support frames. The main body of the support frame is a U-shaped structure with a one-way opening at the bottom, and positioning holes are provided inside the two second sleeves.

[0008] In a preferred embodiment, a second extension tube is inserted into the interior of the second sleeve. The interior of the second extension tube has through holes arranged in a linear array, which match the positioning holes in the second sleeve.

[0009] In a preferred embodiment, brackets are fixedly connected to the top surfaces of the two second extension tubes. The main body of the bracket is a U-shaped structure with a one-way opening at the bottom. A connecting frame is fixedly connected to the top surface of the bracket, and a threaded sleeve is fixedly connected inside the connecting frame.

[0010] In a preferred embodiment, a screw is screwed into the inside of the threaded sleeve, a limit plate is screwed into the outside of the screw, and an L-shaped handle is fixedly connected to the top surface of the screw. The handle and the screw together form a rotation adjustment structure. A connecting plate is hinged to the right side of the branch pipe. A through hole is opened inside the connecting plate, and a bearing is embedded inside the through hole. A bracket is fixedly connected to the bottom surface of the connecting plate. The main body of the bracket is a U-shaped structure with a one-way opening at the top. An ejector bolt is screwed into the inside of the bracket. There are two ejector bolts, which are screwed in a straight array on the left and right sides of the bottom surface of the bracket. The bracket and the ejector bolts together form an ejection structure for the bearing.

[0011] After using the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by providing a screw sleeve fixedly connected in the connecting frame, when in use, the lawnmower can be lifted on one side by gripping the handle and rotating the screw, and the single-sided lifting operation of the lawnmower can be achieved through the meshing transmission between the screw and the screw sleeve installed in the connecting frame, thereby achieving a more practical purpose.

[0013] 2. In this utility model, a first sleeve is fixedly connected to the right end face of the connecting rod, and a first extension tube is inserted inside the first sleeve. Therefore, when the device is not in use, it can be quickly adjusted. When the bearing is damaged and needs to be replaced, the ejector bolt can be rotated and the ejector bolt can be used to push the bearing out, thereby achieving the purpose of quick replacement.
