Description
Technical field
Of the invention is related to a kind of anti-disassembling nut, belongs to fastener areas.
Background technique
Since traditional nut does not have anti-disassembling function, after locking, can easily be torn open using general utility tool
It unloads；Therefore, to prevent layman to be destroyed, steal to equipment, facility or technology, it will usually use tamper in key position
Removing nut is locked, in bridge fastening, the fastening of communication equipment, the fastening of privacy mechanism；But under special circumstances, specially
When industry personnel carry out such as maintenance, the operation of more exchange device, anti-disassembling nut will also meet profession disassembly and require.
Traditional anti-disassembling nut is generally divided into two kinds of forms:
A kind of form is using twisted off type anti-dismounting structure, and specially nut body has one section of cylindrical section and and turret head
Twist into two parts portion, cylindrical section inner hole is threaded hole, for be threadedly engaged, turret head inner hole is the through-hole bigger than screw thread, cylindrical section with
Be provided with groove between turret head, when use by nut in place after, continue to power, turret head can be twisted into two parts, remaining cylindrical section
Part can not be backed out by traditional extracting tool, but the nut appearance after twisting into two parts is different from conventional nut, and it is irregular to twist into two parts face,
The problem of influencing part overall appearance.
Another form is ball-type anti-dismounting structure, and nut interior is provided with two height slots, and section is arc-shaped, radial direction
Depth minus thread turns to and increases, and two balls are equipped in two height slots and are furnished with dedicated plastic inner lining and plastic washer, to protect
Demonstrate,prove ball activity freely, when screwing clockwise, ball is rolled along arc shaped groove, when loosening nut counterclockwise, due to radial dimension
Gradually become smaller, ball is stuck in screw thread, can not loosening nut, to play the role of Anti-dismantling.Such anti-disassembling nut makes
With rear, repair if necessary, more exchange device it is special when, the mode for destroying nut can only be taken to be removed, it is difficult to destroy
It spends larger.
Summary of the invention
The purpose of the present invention is to solve in the case of there are design of part irregular, the profession disassembly of traditional anti-disassembling nut
The problems such as difficulty is larger is removed, and a kind of pair of layman's tamper, the anti-disassembling nut easy to dismantle to professional are provided.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of anti-disassembling nut of the invention, including basal body of nut and nut；
Basal body of nut is the cylindrical part of both ends open, and the inner and outer wall of basal body of nut is threaded rotation direction phase respectively
With internal screw thread and external screw thread, the end of basal body of nut locking end is outward extended with annular stop platform, adds in the outer wall of basal body of nut
Work has spanner slot；
Nut is the annular element that length and basal body of nut length match, and the inwall processing of nut has and basal body of nut outer wall
The internal screw thread that external screw thread matches, the outer wall of nut are multi-prismatic surface；Nut is threaded into basal body of nut outer wall, until nut
Front end face press closer the annular stop platform of basal body of nut locking end end；The tightness that nut is threadedly coupled with basal body of nut is less than
The tightness that basal body of nut is connect with bolt thread.
When anti-disassembling nut is installed, the locking end of anti-disassembling nut is directed at bolt, nut is rotated forward by spanner, by
It is limited in the front end face of nut by the annular stop platform of basal body of nut locking end end, it is same that when cap rotation will drive basal body of nut
Step rotation, so that anti-disassembling nut and bolt be made to tighten；When removing anti-disassembling nut, since nut and basal body of nut screw thread connect
The tightness connect is less than the tightness that basal body of nut is connect with bolt thread, only can be by spiral shell when rotating backward nut by spanner
Cap is unloaded from basal body of nut, and basal body of nut remains attached on bolt, plays the role of Anti-dismantling.To meet maintenance, replacement
The special disassembly demand such as equipment when profession removes anti-disassembling nut, is first unloaded nut by common wrench from basal body of nut
Under, then the special spanner by matching with nut outer wall spanner slot unloads basal body of nut from bolt, realizes to Anti-dismantling
The profession of nut is removed.
Beneficial effect
Anti-disassembling nut structure of the invention is simple, easy to use, and Anti-dismantling effect is reliable, the appearance of anti-disassembling nut and
Make-up process and conventional nut indistinction, can substitute completely conventional nut carry out using.In special dismounting demand, spy can be passed through
Kind spanner removes anti-disassembling nut, meets the special disassembly demands such as maintenance, more exchange device.
Detailed description of the invention
Fig. 1 is the overall radial cross-sectional view of anti-disassembling nut of the present invention；
Fig. 2 is the axial sectional view of basal body of nut in anti-disassembling nut of the present invention；
In figure, 1- basal body of nut；2- nut.
Specific embodiment
The content of the present invention will be further explained with reference to the accompanying drawings and examples:
Embodiment
A kind of anti-disassembling nut of the invention, as shown in Figure 1, including basal body of nut 1 and nut 2；
As shown in Fig. 2, basal body of nut 1 is the cylindrical part of both ends open, the inner and outer wall of basal body of nut 1 is processed respectively
There are the identical internal screw thread of thread rotary orientation and external screw thread, the end of 1 locking end of basal body of nut is outward extended with annular stop platform, in nut
The outer wall of matrix 1 is machined with spanner slot；
Nut 2 is the annular element that length and 1 length of basal body of nut match, and the inwall processing of nut 2 has and basal body of nut 1
The internal screw thread that outer wall external screw thread matches, the outer wall of nut 2 are hexagonal prisms face；Nut 2 is threaded into 1 outer wall of basal body of nut,
Until the front end face of nut 2 presses closer the annular stop platform of 1 locking end end of basal body of nut；Nut 2 is threadedly coupled with basal body of nut 1
Tightness be less than the tightness that connect with bolt thread of basal body of nut 1.
When anti-disassembling nut is installed, the locking end of anti-disassembling nut is directed at bolt, nut 2 is rotated forward by spanner,
Since the front end face of nut 2 is limited by the annular stop platform of 1 locking end end of basal body of nut, nut 2 will drive nut when rotating
Matrix 1 rotates synchronously, so that anti-disassembling nut and bolt be made to tighten；When removing anti-disassembling nut, due to nut 2 and nut base
The tightness that body 1 is threadedly coupled is less than the tightness that basal body of nut 1 is connect with bolt thread, rotates backward nut 2 by spanner
When, nut 2 can only be unloaded from basal body of nut 1, basal body of nut 1 remains attached on bolt, plays the role of Anti-dismantling.
To meet the special disassembly demands such as maintenance, more exchange device, when profession removes anti-disassembling nut, first by commonly pulling
Hand unloads nut 2 from basal body of nut 1, then the special spanner by matching with 2 outer wall spanner slot of nut is by basal body of nut 1
It is unloaded from bolt, realizes and the profession of anti-disassembling nut is removed.
