Description

Technical Field

[0001] This invention relates to the field of production technology of lawnmower lifting frames, and more specifically, to a single-column lawnmower lifting frame. Background Technology

[0002] Lawn mower lifts are primarily used for lawn mower maintenance. Their main structure typically comprises five modules: a chassis for movement, a lifting bracket, a hydraulic pump, and wheel supports. The chassis is characterized by its large length and width to support the lifting bracket, hydraulic pump, and wheel supports. The lifting bracket is characterized by its considerable height to accommodate the height adjustment of the lawn mower lift. Therefore, the lawn mower lift has a relatively large overall length, width, and height. This structural feature results in a significant space requirement for the lawn mower lift, needing both a large base area and sufficient height space to accommodate its placement. When the lawn mower is in normal operation, the lawn mower lift... When not in use, the lawnmower lift requires a significant amount of space from the user. Furthermore, when shipping the lawnmower lift, the manufacturer needs a large container to hold it, consuming considerable logistical resources and increasing costs. Currently, some manufacturers are making the lawnmower lift structure detachable. However, the lawnmower lift has five main modules, and making these modules detachable results in numerous parts, making assembly difficult and inconvenient for users. Secondly, disassembling the hydraulic pump separately requires considerable effort from the manufacturer to load it; otherwise, it is easily damaged during transport should any impact occur. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a single-column lawnmower lifting frame.

[0004] To achieve the above objectives, the innovative aspects of this invention are as follows: its structure has: The base frame is movable, and the center of the base frame has a hollowed-out storage slot; A single-tube column has a hinged sleeve on the base frame. The hinge of the sleeve moves towards the storage slot. The single-tube column is adjustable up and down and is set inside the sleeve. The base frame has a fixing slot to hold the single-tube column. A support frame is hingedly mounted on the top of a single-tube column. The support frame has a clearance groove. When the support frame moves freely on the single-tube column, the single-tube column can pass through the clearance groove. A hydraulic pump is fixed at the bottom of the single-tube column. A detachable ear plate is provided on the clearance groove. The ear plate has a hinge groove. A hinge shaft is provided at the connection between the output end of the hydraulic pump and the hinge groove. The hinge shaft is detachably located inside the hinge groove. The fixed tube is detachably connected to the end of the support frame, and symmetrical wheel supports are provided at both ends of the fixed tube.

[0005] Furthermore, the aforementioned sleeve has several adjustment holes from top to bottom, and the bottom of the single-tube column has a fixing hole. The fixing hole and the adjustment hole are connected by a first pin.

[0006] Furthermore, the bottom of the aforementioned storage slot is sealed with a fixing plate, and the fixing plate has a downward-recessed arc-shaped groove, with symmetrical placement plates at both ends of the arc-shaped groove.

[0007] Furthermore, the end of the aforementioned fixing plate is provided with a detachable U-shaped hoop. When the single-tube column hinge is placed inside the storage groove, the hydraulic pump is placed inside the arc-shaped groove and the U-shaped hoop is correspondingly locked on the top of the single-tube column. The placement plate is used to restrict the hinge movement of the support frame.

[0008] Furthermore, the aforementioned support frame includes two parallel connecting pipes and a rotating rod. The rotating rod is rotatably mounted on the top of the single-tube column and extends to both sides of the single-tube column. The two connecting pipes are symmetrically fixed at both ends of the rotating rod, and a clearance groove is formed between the two connecting pipes. The top of the ear plate is provided with a U-shaped plate, and both ends of the U-shaped plate are provided with fastening bolts. The connecting pipe is provided with threaded holes. The U-shaped plate and the connecting pipe are connected by fastening bolts and threaded holes. The end of the connecting pipe is provided with a through groove, and the through groove is provided with a connecting hole. The fixing pipe is provided with a pin hole, and the connecting hole and the pin hole are connected by a second pin.

[0009] Furthermore, each of the four sides of the aforementioned single-tube column is provided with a triangular plate whose edge is perpendicular to the horizontal plane, and each of the four sides of the fixing groove is provided with a slot. When the single-tube column is inserted into the fixing groove, the three triangular plates are inserted into the slots one by one.

[0010] Furthermore, the hinge groove is provided with symmetrical bearings inside, and a fixed shaft extends outward from the bearings. A connecting groove is provided on the fixed shaft, and a locking block is provided at the end of the hinge shaft. The locking block is locked inside the connecting groove, and the locking block and the connecting groove are connected by a fixing bolt.

[0011] The technical effects and advantages of this invention are as follows: The main components of the lawnmower lifting frame of this invention, including the single-tube column, hydraulic pump, and support frame, can all be folded into the storage slot, saving space. This not only facilitates transportation and reduces the consumption of logistics resources, but also saves users a lot of space when the lawnmower lifting frame is not in use. Furthermore, the folded lawnmower lifting frame only needs to be installed with the ear plate and fixing tube during installation, reducing the assembly difficulty for customers.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1 to 4 In one specific embodiment of the present invention, the structure has the following features: A movable base frame 1, with a storage slot 101 cut out at the center of the base frame 1; The single-tube column 2 has a hinged sleeve 11 on the base frame 1. The hinge movement direction of the sleeve 11 is towards the storage groove 101. The single-tube column 2 is adjustable up and down and is set inside the sleeve 11. The base frame 1 has a fixing groove 12 that holds the single-tube column 2. Support frame 3 is hingedly mounted on top of single-tube column 2. Support frame 3 is provided with clearance groove 13. When support frame 3 moves freely on single-tube column 2, single-tube column 2 can pass through clearance groove 13. Hydraulic pump 14 is fixed at the bottom of single-tube column 2. Removable ear plate 15 is provided on clearance groove 13. Hinge groove 16 is provided on ear plate 15. Hinge shaft 17 is provided at the connection between output end of hydraulic pump 14 and hinge groove 16. Hinge shaft 17 is detachably mounted inside hinge groove 16. The fixing tube 4 is detachably connected to the end of the support frame 3, and the two ends of the fixing tube 4 are provided with symmetrical wheel support members 18.

[0018] In this invention, the principle of disassembling the lawnmower lifting frame is as follows: First, disconnect the output end of the hydraulic pump 14 and the hinge shaft 17. Then, remove the ear plate 15 from the clearance groove 13 and remove the fixing tube 4 from the end of the support frame 3. Lift the single-tube column 2 upwards so that the bottom of the single-tube column 2 leaves the fixing groove 12. Hinge the single-tube column 2 towards the inside of the storage groove 101 so that the single-tube column 2 is placed inside the storage groove 101. Then, hinge the support frame 3 downwards so that the single-tube column 2 passes through the clearance groove 13, allowing the support frame 3 to also be placed inside the storage groove 101. Finally, the lawnmower lift is folded to the size of the base frame 1. All other parts are located inside the storage groove 101, and the fixing tube 4 and ear plate 15 can be placed flat in the packaging box, reducing the packaging volume of the lawnmower lift. The specific assembly process for subsequent customer assembly is as follows: First, hinge the single-tube column 2 upwards so that the bottom of the single-tube column 2 is aligned and placed into the inside of the fixing groove 12, thereby fixing the single-tube column 2 on the base frame 1. Then, hinge the support frame 3 to the top of the base frame 1, install the ear plate 15 inside the clearance groove 13, and install the output end of the hydraulic pump 14 into the inside of the hinge groove 16 through the hinge shaft 17 so that the output end of the hydraulic pump 14 presses against the support frame 3. Finally, fix the fixing tube 4 to the end of the support tube. The whole process completes the assembly of the lawnmower lifting frame.

[0019] When using the lawnmower lift, the customer places the two wheels of the lawnmower on the two wheel support members 18, and then presses down the hydraulic pump 14. The hydraulic pump 14 pushes the support frame 3 to move upward on the single tube column 2, thereby driving the two wheel support members 18 on the fixed tube 4 to move upward, thus lifting one side of the lawnmower upward.

[0020] In this invention, the main components of the lawnmower lifting frame, namely the single-tube column 2, the hydraulic pump 14, and the support frame 3, can all be folded into the storage slot 101, saving space. This not only facilitates transportation and reduces the consumption of logistics resources, but also saves users a lot of space when the lawnmower lifting frame is idle. Furthermore, the folded lawnmower lifting frame only needs to be installed with the ear plate 15 and the fixing tube 4, reducing the assembly difficulty for customers.

[0021] In this invention, as a preferred embodiment, the sleeve 11 is provided with a plurality of adjustment holes 5 from top to bottom, and the bottom of the single tube column 2 is provided with a fixing hole 51. The fixing hole 51 and the adjustment hole 5 are connected by a first pin 52.

[0022] In this invention, when the single-tube column 2 is lifted upwards, the first pin 52 is inserted into the corresponding adjustment hole 5 and fixing hole 51 to fix the single-tube column 2 and sleeve 11. This prevents the single-tube column 2 from moving arbitrarily during the folding process of the lawnmower lifting frame, which would affect the folding and assembly of the lawnmower lifting frame. At the same time, when the single-tube column 2 is inserted into the fixing groove 12, the first pin 52 is also inserted into the corresponding adjustment hole 5 and fixing hole 51 to fix the single-tube column 2 and sleeve 11. This prevents the single-tube column 2 from coming off the fixing groove 12 during the use of the lawnmower lifting frame, which would affect the normal use of the lawnmower lifting frame.

[0023] In this invention, as a preferred embodiment, the bottom of the storage slot 101 is closed with a fixing plate 53, and the fixing plate 53 has a downwardly recessed arc-shaped groove 54, with symmetrical placement plates 55 at both ends of the arc-shaped groove 54.

[0024] In this invention, as a preferred embodiment, the end of the fixing plate 53 is provided with a detachable U-shaped hoop 56. When the hinge of the single tube column 2 is placed inside the storage groove 101, the hydraulic pump 14 is placed inside the arc groove 54 and the U-shaped hoop 56 is correspondingly locked on the top of the single tube column 2. The placement plate 55 is used to restrict the hinge movement of the support frame 3.

[0025] In this invention, the positions of the support frame 3, hydraulic pump 14, and single-tube column 2 in the storage slot 101 are as follows: the single-tube column 2 is folded into the storage slot 101, and the end of the single-tube column 2 is placed flat on the fixing plate 53. At the same time, the U-shaped hoop 56 fixes the single-tube column 2 and the fixing plate 53 to prevent the single-tube column 2 from shaking arbitrarily in the storage slot 101 and to ensure the stability of the single-tube column 2 in the storage slot 101. Secondly, the hydraulic pump 14 protrudes from the outside of the single-tube column 2. When the single-tube column 2 is folded into the storage slot 101, the hydraulic pump 14 will enter the interior of the arc-shaped groove 54 to prevent the fixing plate 53 from pressing against the hydraulic pump 14 and causing damage to the hydraulic pump 14. Finally, the support frame 3 hinges downward. The position of the placement plate 55 can restrict the hinge movement of the support frame 3. This restriction allows the support frame 3 to be placed on the placement plate 55.

[0026] In this invention, as a preferred embodiment, the support frame 3 includes two parallel connecting pipes 31 and a rotating rod 32. The rotating rod 32 is rotatably mounted on the top of the single-tube column 2 and its two ends extend to the two sides of the single-tube column 2 respectively. The two connecting pipes 31 are symmetrically fixed at both ends of the rotating rod 32, and a clearance groove 13 is formed between the two connecting pipes 31. The top of the ear plate 15 is provided with a U-shaped plate 6, and both ends of the U-shaped plate 6 are provided with fastening bolts 61. The connecting pipe 31 is provided with threaded holes 62. The U-shaped plate 6 and the connecting pipe 31 are connected by fastening bolts 61 and threaded holes 62. The end of the connecting pipe 31 is provided with a through groove 63, the through groove 63 is provided with a connecting hole 64, the fixing pipe 4 is provided with a pin hole 65, and the connecting hole 64 and the pin hole 65 are connected by a second pin 66.

[0027] In this invention, the setting of the rotating rod 32 allows the two connecting pipes 31 to hinge on both sides of the single-pipe column 2. The position of the placement plate 55 is located on both sides of the arc groove 54, which corresponds exactly to the position of the two connecting pipes 31. Therefore, when the two connecting pipes 31 hinge downward on both sides of the single-pipe column 2 and pass through the clearance groove 13 to enter the interior of the storage groove 101, the position of the two connecting pipes 31 entering the storage groove 101 corresponds to the position of the placement plate 55, and the two connecting pipes 31 can be directly placed on the placement plate 55.

[0028] In this invention, the U-shaped plate 6 is designed to fix the ear plate 15 and the relief groove 13. That is, the opening width of the U-shaped plate 6 and the width of the relief groove 13 are the same, so that the two ends of the U-shaped plate 6 can be connected and fixed by fastening bolts 61 and threaded holes 62 respectively.

[0029] In this invention, the through groove 63 facilitates the pre-fixing of the ends of the fixing tube 4 and the connecting tube 31, and finally the pin hole 65 and the connecting hole 64 are connected and fixed by the second pin 66.

[0030] In this invention, as a preferred embodiment, each of the four sides of the single-tube column 2 is provided with a triangular plate 7 whose edge is perpendicular to the horizontal plane, and each of the four sides of the fixing groove 12 is provided with a slot 71. When the single-tube column 2 is inserted into the fixing groove 12, the three triangular plates 7 are inserted into the slots 71 one by one.

[0031] In this invention, when the single-tube column 2 is locked inside the fixing groove 12, the four triangular plates 7 are respectively locked inside the slots 71, which stabilize the single-tube column 2 from four directions.

[0032] In this invention, as a preferred embodiment, the hinge groove 16 is provided with symmetrical bearings 72 inside, the bearings 72 extend outward to a fixed shaft 73, the fixed shaft 73 is provided with a connecting groove 74, the end of the hinge shaft 17 is provided with a locking block 75, the locking block 75 is locked inside the connecting groove 74, and the locking block 75 and the connecting groove 74 are connected by a fixing bolt 76.

[0033] In this invention, the process of installing the hinge shaft 17 inside the hinge groove 16 is as follows: the locking block 75 is inserted into the connecting groove 74, and the locking block 75 and the connecting groove 74 are connected by the fixing bolt 76. The setting of the bearing 72 allows the hinge shaft 17 to rotate freely inside the hinge groove 16.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
