Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive hood painting technology, and specifically relates to a hood painting lifting tool. Background Technology
[0002] In automotive painting, the painting of the inner surface of the hood is crucial. Currently, when painting the inner surface of the hood manually, lifting the hood mainly relies on simple tools or direct manual operation. These methods have many drawbacks: Firstly, the lack of specialized tooling to secure the hood results in poor stability during lifting, making it prone to wobbling. This not only affects the uniformity and quality of the paint application but also increases the difficulty of operation for painters and reduces work efficiency. Secondly, existing tools lack safety; the hood may accidentally fall off during lifting due to insecure securing, posing a serious threat to the personal safety of workers.
[0003] Currently, there are existing hood painting fixtures, but their structures are quite complex and inconvenient to operate. Utility Model Content

[0005] A hood painting lifting fixture includes a limiting box body for limiting and positioning the hood U-shaped locking hook. A movable lifting handle is connected to the limiting box body, and a pin assembly is slidably connected to the limiting box body. The pin assembly reciprocates under the drive of a driving component to lock and release the hood U-shaped locking hook.
[0006] Preferably, the limiting box body includes a limiting upper plate and a limiting lower plate on both sides in the thickness direction, a width limiting side plate in the width direction and a length limiting side plate in the length direction, wherein the width limiting side plate and the length limiting side plate form a limiting mechanism.
[0007] Preferably, the pin assembly includes a connecting plate and a pin post, the upper limiting plate and the lower limiting plate are respectively provided with sliding limiting holes that slide with the pin post, the connecting plate is located above the upper limiting plate, and the driving assembly is used to drive the connecting plate.
[0008] Preferably, the drive assembly includes a drive handle and a drive slide rod. The drive slide rod is slidably connected to a slide rod sliding limiter. The upper end of the drive slide rod is connected to the drive handle, and the lower end is connected to the pin assembly. A slide rod limiter is connected to the drive slide rod, and the slide rod limiter is used to limit the position of the drive slide rod, so that the pin is in a stable locked state.
[0009] Preferably, the sliding limit member is an inverted U-shaped limit member, with its lower ends fixed on both sides of the upper limit plate of the limit box. The sliding limit member is a limit compression spring, which is fitted onto the driving slide rod and located between the U-shaped limit member and the limit end of the driving slide rod. The limit end is located at the lower end of the driving slide rod and is connected to the connecting plate.

Detailed Implementation
[0015] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0016] Example 1:
[0017] like Figure 1 As shown in the figure, the present invention provides a hood painting lifting fixture, including a limiting box 1, which is used for limiting and positioning the hood U-shaped locking hook. A movable lifting handle 2 is connected to the limiting box 1, and a pin assembly is slidably connected to the limiting box 1. The pin assembly reciprocates under the drive of the driving assembly to lock and release the hood U-shaped locking hook.
[0018] Specifically, the limiting box 1 includes a limiting upper plate 11 and a limiting lower plate 12 on both sides in the thickness direction, a width limiting side plate 13 in the width direction and a length limiting side plate 14 in the length direction, and the width limiting side plate 13 and the length limiting side plate 14 form a limit.
[0019] Specifically, the pin assembly includes a connecting plate 31 and a pin post 32. The upper limiting plate 11 and the lower limiting plate 12 are respectively provided with sliding limiting holes that slide with the pin post 32. The connecting plate 31 is located above the upper limiting plate 11, and the driving assembly is used to drive the connecting plate 31.
[0020] Specifically, the drive assembly includes a drive handle 41 and a drive slide rod 42. The drive slide rod 42 is slidably connected to the slide rod sliding limit member 43. The upper end of the drive slide rod 42 is connected to the drive handle 41, and the lower end is connected to the pin assembly. The drive slide rod 42 is connected to the slide rod limit member 44, which is used to limit the position of the drive slide rod 42, so that the pin post 32 is in a stable locked state.
[0021] Specifically, the sliding limit member 43 is an inverted U-shaped limit member, with its lower ends fixed on both sides of the upper limit plate 11 of the limit box 1. The sliding limit member 44 is a limit compression spring, which is fitted on the drive slide rod 42 and located between the U-shaped limit member and the limit end 45 of the drive slide rod 42. The limit end 45 is located at the lower end of the drive slide rod 42 and is connected to the connecting plate 31.
[0022] Specifically, the movable lifting handle 2 is slidably connected to the limiting box 1 via the rotating shaft 5, and is rotatably connected to the upper limiting plate 11 and the lower limiting plate 12 via the rotating shaft 5.
[0023] The working principle or operation method of this utility model is as follows: when the drive handle 41 is lifted, the U-shaped locking hook of the cover is inserted into the limiting box 1, and the limiting box 1 is used for initial positioning and limiting. When the drive handle 41 is released, the pin 32 returns to its original position under the action of the compression spring, locking the U-shaped locking hook of the cover.
[0024] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
