Technical Field

[0001] This utility model relates to the field of automobile repair technology, specifically to a mobile lifting device. Background Technology

[0002] Automotive repair is a general term for automobile maintenance and repair. It refers to the process of diagnosing and repairing malfunctioning vehicles using technical means, identifying the cause of the malfunction, and taking measures to eliminate the fault and restore the vehicle to a certain performance and safety standard. It includes major and minor repairs. Major repairs involve repairing or replacing any parts (including basic components) to restore the vehicle to its good technical condition and fully (or nearly fully) restore its lifespan. Minor repairs involve replacing or repairing individual parts to ensure or restore the vehicle's operational capability.

[0003] Patent No. CN214828681U discloses a mobile lift for automobile repair, including a base. The bottom of the base is symmetrically and fixedly equipped with casters. One end of the base is symmetrically and fixedly equipped with a trolley handle. A frame is fixedly installed on one side of the trolley handle at the top of the base. The frame has a lifting mechanism in its inner cavity. The lifting mechanism is fixedly connected to a lifting plate through a slide rod. The top of the lifting plate is connected to a buffer plate through a buffer and shock absorption component.

[0004] To address the problem of existing repair lifting devices being inconvenient to move, the current technology involves installing a trolley handle to facilitate pushing the mobile car repair lift and moving it to any location. However, when the lift raises the car chassis, the small contact area between the lift and the car chassis causes excessive pressure on the chassis, potentially leading to damage and secondary injury.

[0031] The present invention will be further described in detail below with reference to embodiments:

[0032] Example 1

[0033] like Figure 1-6 As shown, this utility model provides a mobile lifting device, including a support platform 1. A cross-shaped groove 11 is provided on one side of the support platform 1. A hydraulic push rod 12 is fixedly connected to the bottom wall of the cross-shaped groove 11. A lifting component 2 is slidably arranged on one side of the support platform 1. An extension component 3 is provided at the upper end of the lifting component 2. A snap-fit ​​component 4 is provided on the inner side of the lifting component 2.

[0034] The lifting component 2 includes a cross-shaped block 21 that is slidably engaged in the cross-shaped groove 11. A T-shaped support plate 22 is fixedly connected to the outside of the cross-shaped block 21. Notches 23 are provided on both sides of the upper end of the T-shaped support plate 22. A rotating block 24 is fixedly connected to the upper outside of the notch 23. A limiting member 25 is fixedly connected to the upper outside of the rotating block 24. A locking block 26 is fixedly connected to the upper outside of the rotating block 24. A through groove 27 is provided through the upper end of the locking block 26. A circular groove 28 is provided at the upper outside of the notch 23. An annular groove 281 is provided on the bottom side of the circular groove 28. A moving groove 29 is provided on the outside of the T-shaped support plate 22.

[0035] The circular groove 28 is located below the through groove 27 and is connected to the through groove 27. The movable groove 29 is connected to the annular groove 281.

[0036] In this embodiment, the extension 31 is placed through the notch 23 so that it can be stored when not in use, preventing it from taking up too much space. The locking block 26 is used to limit the turntable 32, preventing the turntable 32 from disengaging from the notch 23, and controlling the turntable 32 to only rotate in one direction. The connection between the moving groove 29 and the ring groove 281 allows the locking rod 41 inside the ring groove 281 to be moved from the outside of the T-shaped support plate 22.

[0037] Example 2

[0038] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the extension component 3 includes an extension member 31 disposed on the notch 23, a turntable 32 is fixedly connected to one side of the extension member 31, a rotating groove 33 is provided at the lower end of the turntable 32, an arc groove 34 is provided at the top of the rotating groove 33, a first positioning groove 35 and a second positioning groove 36 are provided at the top of the arc groove 34, a through hole 37 is provided at the bottom of the arc groove 34, and a limiting groove 38 is provided at the top of the rotating groove 33.

[0039] The through hole 37 is connected to the first positioning groove 35, the inner wall of the arc groove 34 is rotatably engaged with the locking block 26, the limiting groove 38 is rotatably engaged with the limiting member 25, the rotating groove 33 is rotatably connected with the rotating block 24, the through hole 37 is located at the upper end of the circular groove 28, and the through hole 37 is connected to the circular groove 28.

[0040] In this embodiment, the contact area between the car chassis and the equipment is increased by the extension member 31, thereby reducing the impact force on the car chassis. The first positioning groove 35 is the hole for the extension member 31 in the retracted state, and the second positioning groove 36 is the hole for the extension member 31 in the open state. The through hole 37 allows the upper end of the locking rod 41 to pass freely. The mutual cooperation between the limiting groove 38 and the limiting member 25 prevents the rotating block 24 from disengaging from the rotating groove 33, that is, prevents the extension member 31 from disengaging from the notch 23. The arc groove 34 is used to limit the locking block 26 so that the extension member 31 can only rotate in a specific direction.

[0041] Example 3

[0042] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the snap-fit ​​assembly 4 includes a snap-fit ​​rod 41 that is slidably connected inside the circular groove 28, a baffle 42 that is fixedly connected to the outer surface of the snap-fit ​​rod 41, a spring 43 that is fixedly connected to the lower end of the baffle 42, and a pull rod 44 that is fixedly connected to the lower outer surface of the snap-fit ​​rod 41.

[0043] The baffle 42 is slidably engaged with the annular groove 281, the lower end of the spring 43 is fixedly engaged with the bottom wall of the annular groove 281, the pull rod 44 passes through the interior of the moving groove 29 and is slidably engaged with the moving groove 29, the upper end of the locking rod 41 passes through the interior of the circular groove 28, the through hole 37 and the through groove 27 and is slidably engaged with the first positioning groove 35, and the upper end of the locking rod 41 also passes through the interior of the circular groove 28, the through hole 37 and the through groove 27 and is slidably engaged with the second positioning groove 36.

[0044] In this embodiment, the baffle 42 limits the locking rod 41 to prevent it from dislodging from the circular groove 28 and being placed outside. The spring 43 is used to push the baffle 42 upward so that the upper end of the locking rod 41 can always be placed inside the through groove 27. The locking rod 41 enters the first positioning groove 35 to place the extension 31 in the storage state, and the locking rod 41 enters the second positioning groove 36 to place the extension 31 in the open state.

[0045] The working principle of this mobile lifting device will be explained in detail below.

[0046] like Figure 1-5 As shown, when the extension 31 needs to be opened to support and lift the car chassis, first pull down the lever 44 to move the baffle 42 down along the annular groove 281, compressing the spring 43. At this time, the top of the locking rod 41 can be disengaged from the first positioning groove 35, and then enter the circular groove 28 through the through groove 27 and through hole 37. At this time, the block 24 is no longer blocked by the locking rod 41. Then, the extension 31 can be moved. With the T-shaped support plate 22 remaining stationary, the turntable 32 will rotate around the limiting member 25 until the second positioning groove 36 in the arc groove 34 is rotated to the upper end of the locking block 26. At this time, the extension 31 is flush with the outer end of the T-shaped support plate 22, and the closed extension 31 is transferred to the open state. At this time, the lever 44 can be released. This causes the compressive force on spring 43 to disappear. Under the rebound action of spring 43, it will push the baffle 42 to move upward along the annular groove 281 until the upper end of the baffle 42 moves up to the top wall of the annular groove 281, so that spring 43 can return to its initial state. During the upward movement of baffle 42, baffle 42 will simultaneously drive the locking rod 41 to move upward, so that the upper end of locking rod 41 passes through the through hole 37 and the interior of the circular groove 28 and enters the second positioning groove 36. At this time, under the mutual cooperation of locking rod 41 and second positioning groove 36, the extension part 31 can be prevented from rotating again, thereby keeping the extension part 31 in the open state. Thus, under the joint action of extension part 31 and the outer side of T-shaped support plate 22, the support area of ​​the car chassis is expanded, preventing the support force points of the car chassis from being too concentrated.

[0047] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
