Description

Technical Field

[0001] The utility model relates to the field of a hanger for a hand chain hoist, in particular to a hanger for a hand chain hoist. Background Art

[0002] A hand chain hoist is a manual lifting machine that is easy to use and carry. Before using the hand chain hoist, the hook needs to be hung on a suitable load-bearing frame according to the weight and height of the hoisted object. For a load-bearing frame with a higher height, the hand chain hoist hook needs to be hung on it by other means. For this purpose, a hand chain hoist hanger is specifically designed to facilitate the hand chain hoist to be quickly hung on load-bearing frames at different heights.

[0003] For example, a hanger for a hand chain hoist disclosed in the utility model with authorization announcement number CN220182635U belongs to the technical field of hand chain hoist auxiliary tools. One end of the hand chain hoist is rotatably connected to a hook, and the other end of the hand chain hoist is fastened with a hook through a chain. A hanging box is sleeved on the surface of the hand chain hoist, and an opening is provided on the side of the hanging box. One end of the opening is connected to a placement groove, and the bottom of the placement groove is rotatably connected to a bottom plate. The hanger for the hand chain hoist can store and fix the chain and hook of the hand chain hoist through the arranged hanging box and the placement groove and baffle arranged on the hanging box. The device is suspended by a support rod. When the support rod is used to lift the hoist, the clamping head and the shaft rod will rotate relative to each other, so that the hoist is close to the support rod or shakes repeatedly, which has poor stability and may also block the operator's line of sight, making it inconvenient for the operator below to observe the position of the hoist, affecting the hanging efficiency. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a hanger for a hand chain hoist. Screws are designed at both ends of a threaded tube.

The plug-in tube is positioned according to actual conditions to prevent the operator from being obstructed when hanging the hand chain hoist, thereby affecting the assembly efficiency.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a hanger for a hand chain hoist, comprising a hoist body, a fixed plate formed at the upper position of the front side of the hoist body, a rotatable plug-in tube is installed on the upper end of the fixed plate, a rectangular plug-in hole is opened inside the plug-in tube, a first connecting frame is formed on the lower surface of the plug-in tube, a rotatable screw rod is connected to the first connecting frame through a connecting block, a threaded tube is screwed to the lower end of the screw rod, a second connecting frame is formed at the lower end of the fixed plate, another screw rod is connected to the second connecting frame through a connecting block, and the upper end of the screw rod is screwed to the threaded tube.

[0006] As a preferred technical solution of the utility model, the first connecting frame and the second connecting frame have the same structure, both of which are composed of two plates and a fixed shaft, and the fixed shaft passes through the connecting block at the end of the screw rod.

[0007] As a preferred technical solution of the utility model, the two screws are both screwed together with the threaded tube and the two screws are moved closer to or away from each other when screwed together.

[0008] As an optimal technical solution of the utility model, a hook is installed on the upper end of the hoist body, a movable frame is arranged above the hook, a horizontal axis is arranged on the inner side of the movable frame, the hook can be hung on the horizontal axis, and a symmetrical fixed vertical plate is formed on the upper surface of the movable frame, and forward and backward rollers are arranged on the fixed vertical plate.

[0009] As a preferred technical solution of the utility model, a crossbeam is provided between the roller and the movable frame, and a baffle is connected to the end of the crossbeam via fixing bolts.

[0010] As a preferred technical solution of the utility model, a hook is connected to the bottom of the gourd body through a chain.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] By designing the screws at both ends of the threaded tube, when the threaded tube is rotated, the two screws move closer to or farther away from each other, so that the two screws rotate along the fixed axis, thereby changing the angle of the plug-in tube. The plug-in tube is positioned according to actual conditions to prevent the operator from being obstructed when hanging the hand winch, thereby affecting the assembly efficiency.
