Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and in particular to an auxiliary hook for measuring tape. Background Technology

[0002] Measuring tapes are commonly used measuring tools in daily life. Most measuring tapes use hooks to fix the outer end of the tape strip and pull the tape strip to measure. When measuring with this type of measuring tape, the hook is easy to loosen due to the length of the distance (more than 1.5 meters), causing the outer end of the tape strip to slip off. This makes it inconvenient for a single person to measure and often requires two people to work together. Therefore, an auxiliary hook is needed to assist in the measurement work.

[0003] Existing measuring tape auxiliary hooks (measuring assistants) typically have magnetic adsorption or simple hooking functions. By fixing the end of the measuring tape to the auxiliary hook, and using the magnetic attraction of the auxiliary hook or the hook itself to fix it to the item to be measured, a single person can measure the item, saving labor costs.

[0004] However, existing auxiliary measuring tools require fixing the end of the measuring tape with screws, which is time-consuming. When the screws loosen, the measuring tape will separate from the auxiliary measuring tool, affecting the measurement. Furthermore, the fixed hook structure makes it difficult to adapt to the edges of objects of different thicknesses or shapes. Therefore, an auxiliary hook for measuring tape is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an auxiliary hook for measuring tape, which aims to improve the problems of inconvenient connection between the measuring tape and the hook, easy detachment, and unsuitability of the hook for objects of various thicknesses in the prior art.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a measuring tape auxiliary hook, including a hook body 1. The hook body 1 is integrally molded from high-strength engineering plastic through a precision injection molding process to ensure the overall structural strength and lightweight. An installation groove 3 is provided inside the hook body 1. The shape of the installation groove 3 is precisely matched with the end of the measuring tape 2 to ensure the stability of the connection. The end of the measuring tape 2 is installed inside the hook body 1 and is located inside the installation groove 3. A clamping component is provided inside the hook body 1 to further enhance the reliability of the connection and prevent the end of the measuring tape 2 from accidentally coming off due to pulling during the measurement process. A telescopic component is provided on the outside of the hook body 1. The telescopic component can expand the measurement application range and adapt to the edges of objects of different sizes or shapes. A neodymium magnet 16 is fixedly connected to the bottom of the hook body 1. The strong magnetic force of the neodymium magnet 16 is used to achieve rapid adsorption and fixation with the metal surface, which significantly improves the stability of the measurement starting point.

[0035] The clamping assembly includes a round rod 6, which is slidably connected inside the hook body 1. The round rod 6 is set in a pre-set guide hole inside the hook body 1 and can move and change position inside the hook body 1. A pressing plate 5 is fixedly connected to the bottom of the hook body 1. The pressing plate 5 can be moved by the round rod 6. The two side arms of the pressing plate 5 extend from the opening of the hook body 1 to fix the end 2 of the measuring tape. A spring 9 is sleeved on the outside of the round rod 6. The spring 9 is located between the hook body 1 and the pressing plate 5. The spring 9 presses the pressing plate 5 through the hook body 1, so that the pressing plate 5 continuously presses the measuring tape, making the measuring tape firmly fixed and preventing it from moving. The pressing plate 5 is U-shaped. The two sides of the U-shaped structure are fully enclosed with the hook body 1 to fix the measuring tape. A support groove 17 is opened inside the hook body 1. Spring 9 is located inside the support groove 17. Placing spring 9 inside the support groove 17 protects the spring and optimizes the overall appearance. A ring 7 is installed on the top of the round rod 6. Pulling the ring 7 will move the round rod 6 and lift the pressing plate 5. A limit plate 11 is fixedly connected to the outside of the hook body 1. The limit plate 11 can limit the position of the hanging plate 8. When the user pulls the ring 7 upward, the ring 7 moves the round rod 6. The round rod 6 drives the pressing plate to move upward against the elastic force of spring 9. At this time, the end of the measuring tape 2 can be taken out from the mounting groove 3. When the measuring tape needs to be put in, simply perform the above operation, lift the pressing plate 5 and put the end of the measuring tape 2 into the mounting groove 3. After releasing the pull ring 5, the restoring force of spring 9 will immediately reset the round rod 6 and the pressing plate 5, achieving locking.

[0036] Reference Figure 1 and Figure 5The telescopic assembly includes two support blocks 12, which are fixedly connected to the outside of the hook body 1. The two support blocks 12 serve as the support base for the telescopic assembly. A movable rod 10 is slidably connected to the middle of each support block 12. A through hole is opened in the middle of each support block 12, through which the movable rod 10 passes and is slidably connected. A hanging plate 8 is fixedly connected to the bottom of the two movable rods 10. The hanging plate 8 is connected by the two movable rods 10. The auxiliary hook is hung on the edge of the object being measured through the hanging plate 8. A second spring 14 is sleeved on the outside of the movable rod 10. The second spring 14 pushes the hanging plate 8 to retract. A baffle 19 is fixedly connected to the top of the movable rod 10. The second spring 14 is located between the baffle 19 and the support block 12. The second spring 14, through the limiting of the baffle 19 and the support block 12, ensures that the hanging plate 8 always has a retracting force, ensuring that the hanging plate 8 can be fixed on the object.

[0037] Reference Figures 2-4 The hook body 1 has a groove 13 on its inner side, which ensures the smooth and accurate movement of the pressing plate 5. A slider 18 is fixedly connected to the outer side of the pressing plate 5. The slider 18 is slidably connected inside the groove 13. The slider 18 forms an effective guide by embedding and sliding inside the groove 13, which facilitates the movement of the pressing plate 5. A groove 15 is provided at the bottom of the hook body 1. The neodymium magnet 16 is located inside the groove 15. The neodymium magnet 16 is precisely embedded and fixed inside the groove 15 to ensure that the magnet is flush with the bottom surface and avoids affecting the fit due to protrusion during adsorption. A rubber pad 4 is fixedly connected to the bottom of the hook body 1. The neodymium magnet 16 is located between the hook body 1 and the rubber pad 4. The rubber pad 4 not only provides additional friction and enhances the anti-slip effect on non-magnetic or smooth surfaces, but more importantly, it acts as a buffer and protective layer to effectively prevent the hard hook body 1 or magnet from directly contacting and scratching the surface of the object being tested. It is especially suitable for occasions with high requirements for surface smoothness.

[0038] Working principle: First, pull the ring 7 upwards, which will move the rod 6 and cause the pressing plate 5 at the bottom of the rod 6 to move upwards. Then, put the end of the measuring tape 2 into the mounting groove 3. After putting it in, release the ring 7, and the spring 9 will press the pressing plate 5 to fix the end of the measuring tape 2. This will help fix the hook to the end of the measuring tape 2 for easy measurement. When measuring ferrous metals, the hook body 1 can be placed directly on the surface of the object to be measured. The neodymium magnet 16 at the bottom of the hook will firmly attach it to the object to be measured for length measurement. The rubber pad 4 at the bottom of the hook will protect the metal surface during measurement and prevent damage to the object.

[0039] Secondly, when measuring other items, pull the hanging plate 8. The hanging plate 8 moves inside the support block 12 via the top moving rod 10. At this time, the moving rod 10 will squeeze the spring 14 through the top baffle 19, pulling the hanging plate 8 open and hanging it on the object to be measured. The baffle 19 is squeezed by the pressure of the spring 14 to fix the hook. At this time, the distance measurement can begin.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
