Technical Field

[0001] This utility model relates to the technical field of lawnmower rear cover shafts, and in particular to a lawnmower rear cover shaft with quick-release maintenance function. Background Technology

[0002] The rear cover shaft of a lawnmower (usually referring to the drive shaft or transmission shaft) is the core component connecting the power source and the cutting device, and its design must take into account strength, wear resistance and flexibility.

[0003] After long-term use, the rear cover shaft needs regular maintenance. During use, the aging of the shaft end seal may cause lubricating oil leakage, requiring the replacement of the seal. Oil-impregnated bearings or bushings are prone to wear after long-term use and need to be inspected and replaced. Therefore, it is necessary to design a lawnmower rear cover shaft with quick-release maintenance function. Utility Model Content

[0004] The purpose of this application is to provide a lawnmower rear cover shaft with quick-release maintenance function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: A lawnmower rear cover shaft with quick-release maintenance function includes a mounting tube and a quick-release assembly mounted on the mounting tube. The quick-release assembly includes a shaft tube, a mounting plate, and a mounting groove. Two mounting grooves are formed on the bottom outer wall of the shaft tube. Two mounting plates are fixedly installed on the top of the mounting tube. The two mounting grooves are centrally symmetrical. The shape and installation position of the mounting plates correspond to the mounting grooves. A connecting tube is installed at the center of the shaft tube through a bearing. One end of the connecting tube is threaded and the threaded end is connected to the rotating end of the external lawnmower. The other end of the connecting tube extends into the center of the mounting tube.

[0006] Preferably, a fitting plate is fixedly installed on the inner wall of each of the two mounting slots, and a limiting block is fixedly installed at one end of each of the two fitting plates. The limiting block is made of magnet, and the two fitting plates and the limiting block are arranged symmetrically at the center. A disassembly hole is provided through the outer wall of the mounting tube, and both the mounting tube and the mounting plate are made of ferrous metal.

[0007] Preferably, both mounting plates are curved plates, the mounting groove is an annular groove, a bonding plate is fixedly installed on the top edge of the mounting tube, and a guide plate is fixedly installed on the bottom edge of the shaft tube. Both the bonding plate and the guide plate are annular plates, and the installation positions of the guide plates on the bonding plate and the guide plates are corresponding. Two guide grooves are formed on the outer wall of the guide plate, and two fitting tubes are fixedly installed on the outer wall of the bonding plate. The two guide grooves and the fitting tubes are centrally symmetrically arranged, and the inner wall of the fitting tube is threaded.

[0008] The beneficial effects of this utility model are: by providing a quick-release component, a pry bar is inserted into the disassembly hole, driving the mounting tube to rotate, so that the mounting plate is separated from the fitting plate and the limiting block, and the mounting tube and blade are removed, simplifying the disassembly and assembly steps and improving maintenance efficiency.

[0011] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0012] like Figure 1-3 The lawnmower rear cover shaft with quick-release maintenance function shown includes a mounting tube 1 and a quick-release assembly mounted on the mounting tube 1. The quick-release assembly includes a shaft tube 2, a mounting plate 9, and a mounting groove 10. Two mounting grooves 10 are opened on the bottom outer wall of the shaft tube 2. Two mounting plates 9 are fixedly installed on the top of the mounting tube 1. The two mounting grooves 10 are centrally symmetrical. The shape and installation position of the mounting plate 9 correspond to the mounting grooves 10. A connecting tube 8 is installed at the center of the shaft tube 2 through a bearing. One end of the connecting tube 8 is threaded and the threaded end is connected to the rotating end of the external lawnmower. The other end of the connecting tube 8 extends into the center of the mounting tube 1.

[0013] A fitting plate 11 is fixedly installed on the inner wall of each of the two mounting slots 10. A limiting block 12 is fixedly installed at one end of each of the two fitting plates 11. The limiting block 12 is made of magnet. The two fitting plates 11 and the limiting block 12 are arranged symmetrically at the center. A disassembly hole 7 is opened through the outer wall of the mounting tube 1. Both the mounting tube 1 and the mounting plate 9 are made of iron metal.

[0014] Both mounting plates 9 are curved plates, the mounting groove 10 is an annular groove, the top edge of the mounting tube 1 is fixedly mounted with a bonding plate 3, and the bottom edge of the shaft tube 2 is fixedly mounted with a guide plate 4. The bonding plate 3 and the guide plate 4 are both annular plates, and the installation positions of the bonding plate 3 and the guide plate 4 are corresponding. Two guide grooves 5 are opened on the outer wall of the guide plate 4, and two fitting tubes 6 are fixedly mounted on the outer wall of the bonding plate 3. The two guide grooves 5 and the fitting tubes 6 are centrally symmetrical, and the inner wall of the fitting tubes 6 is threaded.

[0015] Example: The mounting plate 9 on the mounting tube 1 is fitted into the mounting groove 10 of the shaft tube 2, and the fitting tube 6 on the fitting plate 3 is fitted into the guide groove 5 of the guide plate 4. Then, the mounting tube 1 is rotated, the fitting tube 6 slides in the guide groove 5, and the mounting plate 9 slides in the mounting groove 10. The mounting plate 9 and the fitting plate 11 are engaged. The operator uses bolts to fix the fitting plate 3 and the guide plate 4 through the fitting tube 6.
