Technical Field

[0001] The utility model relates to the technical field of manual hoists, in particular to a manual hoist which can be quickly installed. Background Art

[0002] A manual hoist, also known as a hand chain hoist or a chain hoist, is a lightweight, easy-to-carry manual lifting tool. It uses the principle of gear transmission to pull the chain by manpower to achieve the lifting or translation of heavy objects. The manual hoist that can be quickly installed emphasizes the convenience of its design, which is convenient for quick installation and disassembly in a variety of scenarios, thereby improving work efficiency. This type of manual hoist is usually designed with quick connection devices, such as buckles, hooks, etc., which can be quickly connected to the lifting point to reduce installation time. The manual hoist that can be quickly installed is widely used in lifting operations in construction, bridges, ships, machinery, electric power, mining and other industries, especially in scenarios where space is limited and frequent movement or installation is required. Its convenience is particularly prominent.

[0003] The manual hoist can lift the goods by rotating the sprocket, which drives the chain to move, thereby driving the hook at the bottom of the chain to move. After long-term use or short-term high-frequency use of the manual hoist, if it is not cleaned and maintained in time, the dirt and moisture on the chain will accelerate the rust process. During the maintenance process, if the lubricating oil is not evenly applied, it may also lead to poor anti-rust effect of the chain, and then rust. Therefore, a manual hoist that can be quickly installed is proposed to address the above problems. Utility Model Content

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0022] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0023] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0024] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
