Abstract
The utility model discloses a kind of Anti-dismounting nut with nominal torque, including nut body portion is twisted into two parts with what is be arranged on nut body, the portion of twisting into two parts is arranged on the lateral wall of nut body, in handle-shaped, it twists into two parts that portion is smaller close to the thickness value at nut body lateral wall, it is larger far from the thickness value at nut body lateral wall to twist into two parts portion.By Simple spanner pull it is described twist into two parts portion, the anti-disassembling nut is screwed onto on pipe fitting, and after reaching certain torque, the portion of twisting into two parts is broken off, and the anti-disassembling nut fastening can not dismantle.Anti-dismounting nut with nominal torque installation described in the utility model is simple, and the anti-disassembling nut can be effectively prevent, which to be disassembled, causes air-conditioning impaired.
Description
Technical field
The utility model is related to refrigeration technology fields, and in particular to the pipe attaching nut of idle call.
Background technology
Using the nut outside air-conditioning, it is used for piping connection, easy be split to discharge and cause to leak.
Utility model content
The technical issues of the utility model is solved：Prevent the nut outside air-conditioning is split from discharging.
In order to solve the above technical problems, the utility model provides the following technical solutions：A kind of Anti-dismounting nut with nominal torque,
Portion is twisted into two parts with what is be arranged on nut body including nut body, the portion of twisting into two parts is arranged on the lateral wall of nut body, is in
Handle-shaped, twists into two parts that portion is smaller close to the thickness value at nut body lateral wall, twists into two parts portion far from the thickness at nut body lateral wall
Angle value is larger.
Wherein, portion is twisted into two parts close on the outside of nut body far from the thickness value at nut body lateral wall compared to the portion of twisting into two parts
Thickness value at wall is smaller.Compared to the portion of twisting into two parts close to the thickness value at nut body lateral wall, portion is twisted into two parts far from nut body
Thickness value at lateral wall is larger.The processing dimension for twisting into two parts portion is more stringent, excessive, it is not easy to it is broken, it is too small, and it is described anti-
Dismounting nut cannot be fastened on pipe fitting.
By Simple spanner pull it is described twist into two parts portion, the anti-disassembling nut is screwed onto on pipe fitting, reaches certain torque
Afterwards, the portion of twisting into two parts is broken off, and the anti-disassembling nut fastening can not dismantle.
Anti-dismounting nut with nominal torque installation described in the utility model is simple, can effectively prevent the nominal torque tamper
Removing nut, which is disassembled, causes air-conditioning impaired.

Specific implementation mode
A kind of Anti-dismounting nut with nominal torque, the pipe for air-conditioning connect, are located at outside air-conditioning.
As shown in Figure 1, Figure 2, the Anti-dismounting nut with nominal torque is connect with pipe fitting 30, and pipe fitting is equipped with external screw thread, end
It is tapered.
In conjunction with Fig. 3, Fig. 4, the Anti-dismounting nut with nominal torque includes nut body 10 and is arranged on nut body
Twist into two parts portion 20.
Lateral wall such as Fig. 4, nut body 10 is rounded.
If one end of Fig. 3, nut body 10 are in closing in shape.It is equipped with connecting hole in one end of the nut body 10 of closing in shape
11, the internal diameter of connecting hole is less than the internal thread hole 12 of nut body, and taper surface 13 is equipped between internal thread hole and the connecting hole.
In conjunction with Fig. 3, Fig. 4, the portion 20 of twisting into two parts is arranged on the lateral wall of nut body, is in handle-shaped, and the portion of twisting into two parts is close
Notch 21 is equipped at nut body lateral wall.
Such as Fig. 4, the quantity for twisting into two parts portion 20 is two, is symmetrical set, alternatively, setting symmetrical above and below.
Anti-disassembling nut described in the utility model is process by normal ram, and inside processing is processed with normal nut
It is identical, portion 20 is twisted into two parts by punching machine nut processing, there are easy fracture notches 21 at 10 outer circle of nut body.Pass through control
Twist into two parts 20 size of portion thickness and Notch angle A size come control the portion of twisting into two parts 20 fracture torque, such as Fig. 4.
In practical operation, with reference to figure 1, Fig. 2, certain torque, the tapered end and spiral shell of pipe fitting 30 are applied to the portion of twisting into two parts 20
Female taper surface 13 offsets, and twists into two parts the fracture of portion 20, the outer circle of nut body 10 can not stress dismantled, while nut is in tight
Solid fraction state reaches Anti-dismounting nut with nominal torque requirement.
The above content is only the better embodiment of the utility model, for those of ordinary skill in the art, according to this
The thought of utility model, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be understood
For limitations of the present invention.
