The specific embodiment is as follows:

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the present utility model provides a lifting hook technical scheme for convenient lifting:

The lifting hook convenient to hoist comprises a cabin cover 1, and further comprises an internally threaded steel pipe 2, a steel pipe 3, a steel ball 4, a limit rod 5, a grip 6, a connecting piece 7 and a hook 8; a plurality of through holes 1.1 have been seted up on the top surface of cabin cover 1, make things convenient for the lifting hook to install at the different positions in top of cabin cover 1, and internal thread steel pipe 2 cross-section is "T" shape, and internal thread steel pipe 2 vertically sets up its top and inserts in through hole 1.1, and the coaxial one end of fixing at the top of internal thread steel pipe 2 of one end of steel pipe 3, and wherein, the internal diameter of internal thread steel pipe 2 is greater than the internal diameter of steel pipe 3, makes things convenient for the insertion of round bar 5.2. Four guide grooves 3.1 which are obliquely upwards from inside to outside are formed in the top of the steel pipe 3 at equal intervals, and steel balls 4 are arranged in the guide grooves 3.1 in a sliding mode. The lower half part of the limiting rod 5 is vertically provided with a threaded rod 5.1, the upper half part of the limiting rod is provided with a round rod 5.2, the threaded rod 5.1 is arranged in the internally threaded steel pipe 2 through threaded connection, the round rod 5.2 slides in the steel pipe 3 because the outer diameter of the round rod 5.2 is equal to the inner diameter of the steel pipe 3, the middle part of the round rod 5.2 is provided with an annular groove 5.21, and the upper outer edge of the annular groove 5.21 is provided with a chamfer angle, so that the steel ball 4 is partially movably arranged in the annular groove 5.21. The bottom edge of the threaded rod 5.1 is fixed with an annular check ring 5.11, and the upper surface of the annular check ring 5.11 is movably abutted with the lower surface of the internally threaded steel pipe 2 for limiting the insertion depth of the limit rod 5. The bottom end of the threaded rod 5.1 is fixed with a handle 6, the bottom end of the handle 6 is fixed with a connecting piece 7, and the bottom of the connecting piece 7 is rotatably provided with a hook 8.

The working principle is as follows: during installation, the internally threaded steel pipe 2 and the steel pipe 3 are inserted into the through hole 1.1 on the cabin cover 1 together through the handheld grip 6, and the top of the steel pipe 3 penetrates through the outer surface of the cabin cover 1, so that the outlet of the guide groove 3.1 leaks out; the threaded rod 5.1 is driven to rotate by rotating the handle 6, so that the round rod 5.2 moves downwards, the surface of the round rod 5.2 is abutted against the surface of the steel ball 4, the steel ball 4 is pushed out of the outlet part of the guide groove 3.1, the steel ball 4 is clamped on the outer side of the through hole 1.1 on the cabin cover 1, and the lifting hook cannot fall off.

When the steel ball is disassembled, the threaded rod 5.1 is driven to rotate by rotating the handle 6, so that the round rod 5.2 moves upwards, and the steel ball 4 freely slides down from the outlet of the guide groove 3.1 to the annular groove 5.21, so that the internally threaded steel pipe 2 and the steel pipe 3 are taken down from the through hole 1.1 on the cabin cover 1 together.

The device dismantles firm and the safety of installation, conveniently hangs the saddlebag on hook 8, need not at the maintenance in-process, carries the saddlebag on one's back, increases the health burden, improves work efficiency.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
