Description

Quick lock and release nut structure

technical field

The invention relates to a fast lock and release nut structure, in particular to solve the time-consuming problem of screwing and locking of the known screw or screw tube and the nut, through the planning of different apertures of the nut sleeve holes and the lack of grooves When the sliding block is located at the starting end of the missing groove, the diameter of the hole larger than that of the screw or coil can be obtained, and when the sliding block is located at the terminal end of the missing groove, the diameter of the screw or screw can be obtained. The screwing and locking relationship of the screw tube, through the position transfer of the sliding block, can give the nut and the screw rod or the screw tube a quick lock and release nut structure with the convenient effect of quick lock and release operation.

Background technique

Generally, workpieces such as screws or coils used to connect or fix objects must be screwed and locked with nuts to achieve the effect of tightening and fixing. , the nut must be screwed in step by step from the end of the screw or the screw tube until the nut is screwed to the locked position, and then continue to rotate at a certain angle to force the lock to be fastened to achieve the purpose of connecting or fixing the object.

As far as the existing screwing operation method of the nut and the screw rod or the screw tube is concerned, the screwing can only be done step by step, which not only causes great trouble and inconvenience due to the need to constantly change gestures during the screwing process, but also The screwing operation is also quite time-consuming, especially the longer the length of the screw or the screw tube, the more inconvenience and time spent it causes, and relatively when the nut is to be removed from the screw or the screw tube, it is also difficult It is necessary to reversely unscrew the nut step by step, which also causes great inconvenience and time consumption, and is by no means an ideal design.

In addition to the aforementioned problem of time-consuming screw locking between the nut and the screw or the screw tube, if the locking operation of the nut and the screw or the screw tube involves space constraints (such as: the water supply bolt assembly operation of the washstand , the assembly of internal parts of the machine, etc.), it is more likely that due to the narrow working space, it is impossible to select any appropriate tool for the locking and unloading operation, or the tool can only be used for small turning operations in such a narrow space. As a result, the nut can only be screwed into the screw or the screw tube with bare hands, or the tool must be repeatedly pulled out and the gesture changed to barely complete the locking operation, causing inconvenience and time-consuming construction, and even affecting the quality of the locking , It is necessary to try to solve it and improve it.

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 operation 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 added to stop it, 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 even more inconvenient, causing considerable trouble and inconvenience. Therefore, how to develop a more convenient screw lock workpiece for the operation requirements of this type of space is actually the purpose of the present invention.

A preferred implementation mode of the present invention is illustrated by the assembly of water supply plugs. As shown in the figure, the present invention mainly provides a nut body 10 with a predetermined size in terms of the structural design of the nut. The nut body 10 The lower half of the nut body is set as a polygonal clamping part 11, so that it can be used for tool clamping operation and locking, and a ring surface 12 is set on the top of the nut body 10, and a hole diameter larger than The threaded rod or screw tube 31 of the water supply cock 30 that it is built on has a sleeve hole 13 in the outer diameter, and a groove 14 with a predetermined range is cut on the top ring surface 12 of the nut body 10, and the groove 14 occupies The magnitude of the groove is roughly half the circumference of the ring surface 12 of the nut body 10. One end of the grooved part 14 is defined as the starting end A, while the other end is defined as the ending end B, and the top surface of the grooved part 14 is defined by the starting end A. There is a slightly rising slope toward the terminal end B, and a ㄇ-shaped arc-shaped sliding block 20 can be sleeved on the notch 14, and the ㄇ-shaped chute 21 of the sliding block 20 can be slightly larger than the nut body The wall thickness of the missing groove part 14 of 10 provides an appropriate activity margin, and the lower end of the inner groove wall on the outside or inside of the U-shaped chute 21 of the sliding force block 20 is an elongated hook-shaped embedded buckle 22. By hooking the embedded buckle 22 on the lower edge of the nut body 10, the sliding force can be restricted from breaking away from the notch 14, and at the same time, it can be ensured that the sliding block 20 can be lifted from the notch 14. A stable reciprocating sliding adjustment is made between the starting end A and the ending end B, and the inner arc surface of the sliding block 20 is provided with a threaded surface 23 that fits the screw rod or the screw tube 31 that is assembled with it.
