Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 4, a hook structure of a steel tape includes a connecting member 1 for connecting with a tape and a hook body 2 fixed to the connecting member 1, where the connecting member 1 includes a vertical portion 10 and a bending portion 11 at one end of the vertical portion 10, the hook body 2 is made of a flexible material, the hook body 2 includes a rear end surface 2b opposite to the tape body and a front end surface 2a opposite to the rear end surface 2b, a magnet seat 3 for accommodating a magnet is disposed on the front end surface 2a of the hook body 2, a slot 4 is disposed on one side surface of the hook body 2, and the bending portion 11 is inserted and fixed in the slot 4, and a magnet 5 is disposed in the magnet seat 3 and fixed to the bending portion 11. A fin 12 is formed at both sides of the junction of the bent portion 11 and the vertical portion 10.

In the above structure, the magnet is directly fixed with the bent part 11 of the connecting piece 1, and when the ruler hook main body 2 is matched with the bent part 11, the ruler hook main body is covered outside the magnet, so that the magnet can be further positioned. The structure can effectively prevent the magnet from being separated. And because the setting of magnet for can be fixed at the measurement initial position through the mode that the magnet adsorbs when the ruler hook main part 2 can't be hooked at the measurement initial position, in addition, can adsorb some small-size metal article through the magnet. When the tape of the tape measure is retracted into the tape measure, the tape hook main body 2 made of flexible materials collides with the tape measure main body, so that most of impact can be absorbed, and damage caused by the impact is reduced.

Referring to fig. 1 to 2, specifically, as an embodiment of the present application: the magnet base 3 comprises a first through hole 101 arranged on the hook body 2, a second through hole 102 aligned with the first through hole is correspondingly arranged on the bending part 11, and the magnet 5 is provided with two groups of cylindrical magnets 5a which are inserted and fixed in the second through hole 102.

The cylindrical magnet 5a comprises a first part positioned in the first through hole 101 on the front end surface 2a of the ruler hook main body 2 and a second part positioned in the first through hole 101 on the rear end surface 2b of the ruler hook main body 2, wherein the first part extends out of the first through hole of the front end surface or is flush with the first through hole end surface of the front end surface, so that the cylindrical magnet 5a can be attached to the metal surface when the ruler hook main body 2 is adsorbed on the metal surface; the second part is positioned in the first through hole on the rear end face, so that when the tape of the tape measure main body is completely retracted, the cylindrical magnet 5a on the tape hook main body 2 and the metal part on the tape measure main body 2 are adsorbed and not attached, and the adsorption state can be relieved without large force while the tape hook main body 2 is limited.

Referring to fig. 3 to 4, as another embodiment of the present application: the magnet seat 3 comprises a limiting groove 200 arranged on the front end face 2a of the hook body 2, the magnet 5 is a bar-shaped magnet 5b, the bar-shaped magnet 5b is arranged in the limiting groove 200, and a key groove 11a matched with the shape of the end face of the lower end of the bar-shaped magnet 5b is arranged on the end face of the bending part 11. A stop hole 11b is arranged in the key groove 11a, and a stop rib 11c matched with the stop hole 11b in shape is arranged in the slot 4 of the hook body 2. In embodiment 2, the covering area of the covering member of the hook body 2 for the magnet is increased, and the fixing firmness of the magnet can be further increased. And the structure is simple, and the assembly is easier.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The foregoing embodiments and description of the invention have been provided in the present application for the purpose of illustrating the principles of the invention and is subject to various changes and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be within the scope of the claimed invention.
