[0002] The tape measure is a widely used and easy-to-use measuring instrument. When using the tape measure, the ruler hook is usually hooked at the starting end of the measured position. When measuring metal parts, especially most of them contain magnetic materials such as iron, a magnet is also set on the hook of the ruler to adsorb on the measured metal part, so that the ruler hook is not easy to slip off, thereby facilitating the measurement of the size of the metal part.

[0003] When measuring a measuring object, the ruler hook is usually hooked on or pressed against the measuring object. However, when the end face is subjected to a large external force or a large vibration, especially when the ruler hook is quickly recovered with the ruler tape, the ruler hook is easy to hit other objects and generate vibration, which may cause the magnet to loosen and fall off from the hook portion of the ruler hook. In addition, when measuring a measuring object that cannot be hooked, such as the ground or wall, two people are required to cooperate, which is inconvenient for users. For this reason, we propose an anti-falling magnet ruler hook. Utility Model Content

[0024] Embodiment 1

[0025] See also Figure 1-6 The utility model provides a technical solution: an anti-drop magnet ruler hook, comprising: a ruler hook body 1, the ruler hook body 1 comprises a connecting portion 11, a hook portion 12 is fixedly arranged at the end of the connecting portion 11, the ruler hook body 1 is coated with rubber to prevent the thin tip of the ruler hook body 1 from injuring the user, the hook portion 12 is used to support or hook the measuring piece, and the connecting portion 11 is used to connect the ruler tape.

[0026] The first adsorption component 2 is arranged on the hook portion 12, and the first adsorption component 2 is used to make the ruler hook body 1 adsorb on the metal measuring piece and not easy to loosen and fall off from the ruler hook body 1;

[0027] The second adsorption component 3 is symmetrically arranged on both sides of the hook portion 12. The second adsorption component 3 is used to make the ruler hook body 1 adsorb on the ground or wall or other objects that cannot be hooked.

[0028] When measuring a metal measuring piece, the magnet 22 of the first adsorption component 2 can be adsorbed on the metal measuring piece through the first adsorption component 2, so that the ruler hook body 1 is adsorbed on the metal measuring piece, effectively preventing the ruler hook body 1 from slipping off the metal measuring piece, facilitating the user to measure the metal measuring piece, and when in use, the magnet 22 is not easy to loosen and fall off from the hook portion 12 of the ruler hook body 1 to avoid affecting the use; the second adsorption component 3 can make the ruler hook body 1 adsorbed on the ground or wall and other measuring objects that cannot be hooked, so that when measuring, there is no need for two people to cooperate with each other, and one person can complete the measurement, which is convenient for the user.

[0029] Embodiment 2

[0030] The first adsorption component 2 includes a mounting groove 21 arranged on the hook portion 12. The mounting groove 21 is formed by stamping. A rubber pad 23 is fixedly arranged on the side wall of the mounting groove 21. When the magnet 22 is embedded in the mounting groove 21 for installation, the magnet 22 will squeeze the rubber pad 23 on the side wall of the mounting groove 21, so that the rubber pad 23 is squeezed and deformed, so that the gap between the magnet 22 and the mounting groove 21 can be filled by the rubber pad 23, so as to increase the tightness of the magnet 22 after installation. The part of the rubber pad 23 protruding from the end face of the hook portion 12 after being squeezed can be cut by a blade.

[0031] A magnet 22 is fixedly arranged in the mounting groove 21 of the hook portion 12. After the magnet 22 is installed in the mounting groove 21, the outer end surface of the magnet 22 is flush with the end surface of the hook portion 12. A mounting hole 24 is arranged on one side of the mounting groove 21. The magnet 22 is fixed to the hook portion 12 of the ruler hook body 1 by screws through the mounting hole 24. In combination with the rubber pad 23, the tightness of the magnet 22 after installation can prevent the magnet 22 from loosening and falling off from the hook portion 12 of the ruler hook body 1 during use.

[0032] Embodiment 3

[0033] The second adsorption assembly 3 includes fixed blocks 31 symmetrically fixedly arranged on both sides of the hook portion 12 , a rotating block 32 is rotatably arranged on one side of the fixed block 31 away from the hook portion 12 via a rotating shaft, and a sliding sleeve 33 is fixedly arranged on the other end of the rotating block 32 .

[0034] A sleeve 314 is fixedly provided at the lower end of the sliding sleeve 33, and a support rod 34 is slidably provided in the sleeve 314. A guide block is symmetrically fixed on the upper side of the support rod 34, and a guide groove is symmetrically provided on the inner wall of the sleeve 314. The guide block slides in the guide groove to guide the support rod 34 to slide up and down in the sleeve 314. A cavity 310 is provided inside the lower side of the support rod 34, and a suction cup 35 is fixedly provided at the lower end of the support rod 34.

[0035] A conical plate 311 is fixedly arranged in the cavity 310 of the support rod 34, and the conical plate 311 is a circular ring that matches the inner wall of the cavity 310. A flow port 315 is penetrated through the lower end of the conical plate 311, and a ball 312 is clamped in the flow port 315. A sealing gasket is fixed on the lower side of the ball 312 so that the ball 312 can effectively seal the flow port 315 to ensure the adsorption of the suction cup 35. A spring 313 fixedly connected to the upper end of the cavity 310 is fixedly arranged on the upper end of the ball 312. The cavity 310 is located on the upper side of the conical plate 311 and is symmetrically connected to the through hole 36.

[0036] When measuring an object that cannot be hooked on the ground or wall, the support rod 34 is pressed down to move down along the sleeve 314, so that the suction cup 35 can be pressed down and fit on the object that cannot be hooked on the ground or wall. When the suction cup 35 fits and presses on the ground or wall, the gas in the suction cup 35 will flow upward into the cavity 310 and exert a certain impact force on the ball 312, so that the ball 312 moves upward out of the flow port 315. The spring 313 is compressed so that the gas can pass through the flow port 315 and be discharged to the outside through the through hole 36. After the gas is discharged, the ball 312 moves down into the flow port 315 under the elastic force of the spring 313, so that the external gas is prevented from entering the suction cup 35 through the flow port 315, so that the suction cup 35 is adsorbed on the object that cannot be hooked on the ground or wall, and the ruler hook body 1 is adsorbed and fixed, so as to facilitate the use of the user.

[0037] A slide bar 37 that is magnetically attracted to the magnet 22 is slidably arranged in the slide sleeve 33. The slide bar 37 slides in the slide sleeve 33 to abut against the outer end surface of the magnet 22 or the rear end of the hook 12 located in the mounting groove 21. The slide bar 37 is adsorbed and fixed by the magnet 22, thereby further preventing the hook 12 from rotating around the rotating block 32 during measurement, thereby increasing the adsorption effect of the suction cup 35 and ensuring the measurement result; and when measuring, when the front end of the hook 12 is pressed against the measuring piece, the rotating block 32 and the fixed The block 31 rotates to rotate the slide bar 37 to the rear side of the hook 12, and the magnet 22 adsorbs the slide bar 37 to keep the second adsorption component 3 from causing any obstruction to the hook 12 pressing against the measuring piece. When the hook 12 is hooked on the measuring piece, the slide bar 37 is rotated to the front end of the hook 12, and the slide bar 37 is slid to abut against the outer end surface of the magnet 22, so that the magnet 22 adsorbs the slide bar 37 to avoid causing any obstruction to the hook 12 hooking on the measuring piece. When the tape is retracted, the slide bar 37 can be rotated to the front side of the hook 12.

[0038] Limit blocks 39 are symmetrically fixed on the upper and lower sides of the inner wall of the sliding sleeve 33, and limit grooves 38 matched with the limit blocks 39 are symmetrically opened at the upper and lower ends of the sliding rod 37. The limit blocks 39 slide in the limit grooves 38, and the limit grooves 38 do not pass through the two side ends of the sliding rod 37 to prevent the sliding rod 37 from slipping off the sliding sleeve 33. The setting of the limit grooves 38 of the limit blocks 39 can guide and limit the sliding of the sliding rod 37 in the sliding sleeve 33.
