Description

Quick change water treatment membrane test unit nut

Technical Field

The utility model relates to the field of locking nuts, in particular to a quick-change water treatment membrane test unit nut.

Background

The nut is a common fixed part in mechanical equipment, and is often used with a screw rod in a matching way. At present, the thread locking structure is mostly of an integral nut and screw rod screwing structure, when the thread locking structure is used, the nut is detached from the screw rod, the nut is required to be screwed off along the screw rod, time and labor are wasted, the situation requiring quick disassembly and quick assembly is inconvenient, and a large amount of labor and time are wasted.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a quick-change water treatment membrane test unit nut which has the advantages of realizing the functions of quick unscrewing and quick locking and saving labor and time.

The technical purpose of the utility model is realized by the following technical scheme:

the utility model provides a quick change water treatment membrane test unit nut, includes the nut body, it has the locking hole that is the slope setting to open in the nut body, set up screw thread section and lower screw thread section on the inner wall in locking hole, it sets up on relative side to go up screw thread section and lower screw thread section.

Furthermore, a first inclined section with a smooth surface is arranged below the upper thread section, and the first inclined section and the lower thread section are equal in height; and a second inclined section with a smooth surface is arranged below the upper thread section, and the second inclined section has the same height as the upper thread section.

Further, the surface roughness of the first inclined section and the second inclined section is Ra6.3.

Furthermore, a plurality of arc-shaped finger grooves are formed in the outer side of the nut body.

Furthermore, the number of the finger grooves is four, and the four finger grooves are distributed in an even cross shape.

In conclusion, the utility model has the following beneficial effects:

1. when the nut is fixed, the nut can be quickly placed at the bottom end of the screw rod through the locking hole, two sides of the screw rod which are just symmetrical when the nut is rotated by hands are locked through the first thread section and the second thread section, the nut can be quickly assembled by rotating the nut by half a circle, and quick disassembly can be realized by rotating the nut by half a circle in the opposite direction;

2. when the diaphragm is replaced, the nut can be quickly disassembled and assembled, labor and time are saved, and the working efficiency is improved.

Drawings

FIG. 1 is a schematic structural diagram of a nut of a quick-change water treatment membrane test unit;

fig. 2 is a schematic cross-sectional view of a quick-change water treatment membrane test unit nut.

In the figure, 1, a nut body; 11. a finger groove; 2. a locking hole; 21. an upper thread section; 22. a lower thread section; 23. a first inclined section; 24. a second inclined section.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example (b): a quick change water treatment membrane test unit nut, as shown in figure 1, includes nut body 1, and the outside of nut body 1 is opened has curved finger groove 11, and the quantity of finger groove 11 is four, and four finger grooves 11 are even cross distribution. When the nut is rotated, the finger groove 11 is mainly used for accommodating fingers, so that a worker can rotate the nut by force conveniently.

Referring to fig. 1 and 2, a nut body 1 is provided with a locking hole 2 which is obliquely arranged, and the locking hole 2 is located in the middle of the nut body 1. The locking hole 2 and the central axis of the nut body 1 form an included angle of 16 degrees. The inner wall of the locking hole 2 is provided with an upper thread section 21 and a lower thread section 22, and the upper thread section 21 and the lower thread section 22 are arranged on opposite side surfaces. When the nut is locked, two surfaces of the screw are respectively in threaded fit with the upper thread section 21 and the lower thread section 22, and the screw is locked.

As shown in fig. 1 and 2, a first inclined section 23 with a smooth surface is arranged below the upper thread section 21, and the first inclined section 23 is as high as the lower thread section 22; a second inclined section 24 with a smooth surface is arranged below the upper thread section 21, and the second inclined section 24 is equal to the upper thread section 21 in height. Through setting up first slope section 23 and second slope section 24, in order to increase the sectional area of upper and lower opening, conveniently embolia the nut fast. Wherein the surface roughness of the first 23 and second 24 slanted segments is ra 6.3. The first inclined section 23 and the second inclined section 24 are smooth, friction resistance between the screw and the locking hole 2 is reduced, and the nut is conveniently sleeved on the screw.

The specific implementation process comprises the following steps: in the process of mounting the quick-change nut, the quick-change nut can be quickly placed at the bottom end of the screw through the locking hole 2, then a worker holds the nut through the finger groove 11, then the worker rotates the nut with hands, and after half a turn, the nut and the screw are locked; when the nut is disassembled, the nut is rotated in the opposite direction for half a turn, so that the quick assembling and disassembling functions of the nut are realized, the labor and the time are saved, and the working efficiency is improved.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
