Description

Quick lock nut structure (2)

The invention relates to a quick-locking nut structure (2), which is mainly for solving the problem that the screwing and unloading operation of the conventional screw (tube) and the nut is too time-consuming, and the different apertures are planned and lacked through the nut sleeve hole. The sliding block sleeved by the groove portion cooperates to make the sliding block larger than the diameter of the screw (tube) when the sliding block is located at the starting end of the notch portion, and obtain the pair of screw when the sliding block is located at the terminating end of the notch portion The screw-locking relationship of (tube), so that by the positional transfer of the sliding block, it can be given a convenient function for quick locking operation of the nut and the screw (tube).

According to the screw (or screw), which is generally used to connect or fix objects, it must be screwed with a nut to achieve the effect of tightening and fixing, and the screw and the screw (tube) are screwed together. In the lock-unloading operation, the nut must be screwed in step by step from the end of the screw (tube) until the nut is screwed to the locked position, and then rotated at a certain angle to lock and fasten, to achieve the purpose of connecting or fixing the object. .

In terms of the screwing operation mode of the existing nut and the screw (tube), since the screwing can be performed only in a step-by-step manner, not only the gesture must be constantly changed during the screwing process, but also great trouble and inconvenience, and the screwing is provided. The operation is also quite time consuming. In particular, the longer the length of the screw (tube), the more inconvenient and time-consuming it is, and the relative need to gradually remove the nut from the screw (tube). The reverse rotation of the nut, which also causes great inconvenience and time consumption, is hardly called the ideal designer.

In addition to the time-consuming problem of screwing the screw and the screw (tube), if the locking operation of such a nut and the screw (tube) involves space limitation (such as the water supply plug assembly operation of the washstand) , the internal mechanical parts of the machine ‧ ‧ ‧, etc., more likely due to the narrow working space, can not use the appropriate tools for locking operations, or the tools in these narrow spaces, can only be a small amount of rotation The operation causes the nut to be screwed into the screw (tube) by hand, or the tool must be continuously re-drawn and the gesture changed, so that the locking operation can be reluctantly completed, resulting in inconvenience and time consuming of the construction, and even affecting the lock.
