Technical Field
[0001] The utility model relates to the technical field of explosion-proof oil measuring tape equipment, in particular to an explosion-proof oil measuring tape. Background Art
[0002] An explosion-proof oil measuring tape is a special measuring tool, mainly used to measure the depth of oil or water level in containers such as oil tankers and oil storage tanks. Its design takes explosion-proof functions into consideration to adapt to possible flammable and explosive environments. When using an explosion-proof oil measuring tape, it is generally necessary to apply water testing paste or oil measuring paste on the tape to assist in measurement. After the measurement, the tape needs to be fully retracted to avoid damage. At the same time, before measurement, it is necessary to confirm the object and environment to be measured, select the appropriate measurement method and measurement position, ensure that the tape is parallel to the surface of the object to be measured, and avoid placing it on sharp objects to avoid scratching the surface of the tape or damaging the measurement accuracy.
[0003] The explosion-proof oil measuring tape has explosion-proof characteristics in structure, which is usually reflected in its material selection and manufacturing process. This kind of tape is made of materials that are not easy to generate static electricity or sparks to reduce the risk of fire sources that may be caused during the measurement process. At the same time, its design also takes into account the safety of use in flammable and explosive environments. For example, its surface may adopt an anti-slip design to ensure stable operation during use. When in use, the explosion-proof oil measuring tape uses its tape measure mechanism to adjust and measure the length. The user can manually pull out the tape measure and insert it into the oil or water to be tested until the tape body touches the bottom. At this time, the user can determine the depth of the oil or water by reading the scale on the tape measure. In order to increase the accuracy of the measurement, the explosion-proof oil measuring tape is usually also equipped with water testing paste or oil measuring paste. These pastes can be applied to the tape body. When the tape body comes into contact with the liquid, the paste will form a clear boundary on the liquid surface, thereby helping the user to read the measurement value more accurately.
[0004] However, during the winding process, the tape may twist or curl. This may be caused by uneven tape material, improper winding tension or incorrect winding method. A twisted or curled tape not only affects the appearance, but may also affect the accuracy of the measurement. Improper winding or poor tape quality may cause the tape to be damaged such as wear, breakage or deformation. Damage to the tape will directly affect the service life and measurement accuracy of the tape. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide an explosion-proof oil measuring tape to solve the problem that the tape may be twisted or curled during the winding process. This may be caused by uneven tape material, improper winding tension or incorrect winding method. The twisted or curled tape not only affects the appearance, but also may affect the measurement accuracy. If the winding operation is improper or the tape quality is poor, the tape may be damaged by wear, breakage or deformation. The damage of the tape will directly affect the service life of the tape and the technical problem of measurement accuracy.

[0019] By adopting the above technical solution, the rocker and the handle cooperate with each other so that the winding disc can rotate in the fixed frame, so that the measuring tape body can be better retracted and released on the winding disc.
[0020] In summary, the utility model mainly has the following beneficial effects:
[0021] The utility model clamps the tape measure body between the pulleys through the cooperation between the fixed block, the movable block and the first spring, which can limit the tape measure body and assist the tape measure body in being retracted and released. The performance of the spring itself can make the pulley and the movable block move in the fixed block. With this structure, the tape measure body can always be kept in a flat state for being retracted and released, thereby solving the problem that the tape may be twisted or curled during the rewinding process. This may be caused by uneven tape material, improper rewinding tension or incorrect rewinding method. The twisted or curled tape not only affects the appearance, but also may affect the accuracy of measurement. If the rewinding operation is improper or the tape measure quality is poor, the tape may be damaged by wear, breakage or deformation.

[0034] When in use, the tape measure body 5 is clamped between the pulleys 20 through the cooperation between the fixed block 16, the movable block 17 and the first spring 18, which can limit the tape measure body 5 and assist the tape measure body 5 to be retracted and released. Through the performance of the first spring 18 itself, the pulley 20 and the movable block 17 can be moved in the fixed block 16. With this structure, the tape measure body 5 can always maintain a flat state for retraction and release, thereby solving the problem that the tape may be twisted or curled during the rewinding process.
