Quick locking-and-unlocking nut structure

Abstract

The invention provides a quick locking-and-unlocking nut structure. The technical scheme is that a trepan boring which is larger than a screw in bore diameter is formed in a nut, a notch portion with a preset range is arranged at the top edge of the nut, and an embedded guide groove is formed in the outer circumferential surface corresponding to the range of the notch portion; a forced slider nested in the notch portion is enabled to slide stably by the embedded guide groove, and a threaded surface matching with the screw is manufactured at the inner edge of the forced slider; a hole-expansion arc groove is formed in a position, opposite to the trepan boring, at the starting end of the notch portion, while a hole-shrinkage threaded portion is arranged in a position, opposite to the trepan boring, at the stopping end of the notch portion; when the forced slider is positioned at the starting end of the notch portion, the nut is directly sleeved into a threaded and locked position, the forced slider is pushed towards the stopping end of the notch portion so as to allow the threaded surface of the forced slider to match with the hole-shrinkage threaded portion to be fastened and threaded with the screw, and then the nut is easily rotated to be further fastened and locked. By the quick locking-and-unlocking nut structure, threading operation of the nut and the screw can be conveniently and rapidly implemented without being restricted by space.

Description

technical field [0001] The present invention relates to a fast lock-and-release nut structure, mainly to solve the problem that the conventional screw (or screw tube) and nut screw lock-and-release operation is too time-consuming. Background technique [0002] At present, workpieces such as screws (or screw tubes) that are generally used to connect or fix objects usually must be screwed and locked with nuts to achieve the effect of tightening and fixing. In the screw locking and unloading operation, the nut must be screwed in step by step from the end of the screw (or screw tube) until the nut is screwed to the locked position, and then continue to rotate at a certain angle to tighten the forced lock to achieve a connection or The purpose of the fixed object. [0003] As far as the existing screwing operation method of the nut and the screw rod (or screw tube) is concerned, it can only be screwed in a step-by-step manner. Simultaneously, its screw setting operation is also...

Problems solved by technology

[0003] As far as the existing screwing operation method of the nut and the screw rod (or screw tube) is concerned, it can only be screwed in a step-by-step manner. Simultaneously, its screw setting operation is also quite time-consuming, especially the longer the length of the screw (or screw tube), then the inconvenience and time it causes are more significant, and relatively when you want to remove the nut from the screw rod (or screw tube) When removing it, it is also necessary to unscrew the nut step by step in the reverse direction, which also causes great inconvenience and time consumption, and it is difficult to call it an ideal design.

[0004] In addition to the time-consuming problem of screwing and locking the aforementioned nut and screw (or screw), if the locking operation of this type of nut and screw (or screw) involves space constraints (such as: the water supply of the washstand Bolt assembly operations, assembly of internal parts of the machine, etc.), it is more likely that due to the narrow working space, it is impossible to select appropriate tools for locking and unloading operations, or the tools can only be used for small pulls in such narrow spaces. As a result, it can only screw the nut into the screw (or screw tube) with bare hands, or it is necessary to constantly pull out tools and change gestures to barely complete the locking operation, causing inconvenience and time-consuming construction, and even Affects the quality of its lock setting, and it is necessary to try to solve it and improve it

[0005] Generally, the water supply plug of the washstand is assembled in such a way that the water inlet pipe of the water supply plug is usually set as a coil section, and the screw section is inserted under the countertop in accordance with the preset assembly holes on the countertop of the washstand, and then the water supply plug is placed under the countertop. The attached forced lock nut is screwed in from the end of the screw tube section, and then screw the forced lock nut into the inner end of the screw tube section sequentially until the forced lock nut touches the bottom of the washstand, forming a forced lock clamping device for the washstand And the water supply plug is fastened and assembled on the washstand, and its assembly is completed in this way. During its operation, due to the limited space under the washstand, if the drainage pipe or its supporting column is blocked, the other The work space will be narrower, and the plumbers or practitioners who are generally engaged in the assembly of this type of water supply system rarely have thin women, and the general men are relatively tall, so they operate the forced lock in such a narrow space The lock setting of the nut is more in the way, causing considerable trouble and inconvenience. Therefore, how to develop a more convenient screw lock workpiece according to the operation requirements of this type of space is actually the goal of this invention.
