Abstract
The utility model discloses a thread connection with locking function mainly includes bolt, steel ball, holding screw. The bolt is hollow structure, and there is the threaded holes and taper hole inside, and the bolt head has radial opening, and the steel ball is installed inside the bolt, and holding screw installs inside the bolt to contact with the steel ball. The utility model has the characteristics of simple structure, locking reliable, a lot of dismantlement reduction anti -loosening performance, it uses to be fit for multiple mechanical equipment.
Description
Technical field
This utility model relates to a kind of thread connection, specifically a kind of thread connection with locking functions.
Background technology
At mechanical field, for the ease of the manufacture of machine, installation, transport, maintenance and raising labor productivity, people widely use various thread joined structure, if the connectors such as common bolt, nut are exactly typical thread joined structure.
Thread connection generally can self-locking conditions satisfied, and, after screwed tight, the frictional force between screw bolt and nut, between bolt and securing member supporting surface also can stop bolt to get loose voluntarily.But, in the occasion having shock and vibration, variations in temperature or load change, the frictional force between screw pair may reduce or pop-off, after this phenomenon repeatedly repeats, arises that the phenomenon that bolt gets loose naturally, ultimately results in the inefficacy of thread connection.Thread connection was once lose efficacy, and the lighter can affect the normal operation of machine, and serious security incident then can occur severe one.
The root problem of locking thread is in that to prevent the relative motion of screw pair.Therefore, in order to prevent getting loose of thread connection, it is ensured that couple safe and reliable, the substantial amounts of experience that people also accumulate, have found much locking method.Common anti-loose method such as spring washer, self-locking nut, double nut, split pin, stop washer or adopt bonding, riveted joint etc. to force locking measure.
Utility model content
The purpose of this utility model is just to provide a kind of thread connection with locking functions.
To achieve these goals, the technical solution of the utility model is: a kind of thread connection with locking functions, mainly includes bolt, steel ball, holding screw.Bolt is hollow structure, and there are screwed hole and taper hole in inside, and bolt head has radially gap, and steel ball is arranged on inside bolt, and holding screw is arranged on inside bolt, and contacts with steel ball.
Before use, the taper hole position within bolt put into by steel ball, and holding screw is arranged on bolt internal whorl hole site, and does not have extruding force between steel ball.
When two machine components are fastened by needs, it is first according to the occupation mode of conventional bolt, two machine components are fastened, then undertaken tightening by holding screw.
In the process tightening holding screw, holding screw promotes steel ball to travel forward in bolt taper hole, and extrude taper hole by steel ball, owing to bolt head has radially gap, therefore, bolt head actually can outwards expand slightly, thus the pressure strengthened between bolt head and connected piece, finally make to screw and mutually compress between screw thread, reach locking purpose.
This utility model has simple in construction, locking reliably, repeatedly dismantles the feature not reducing anti-loosening property, is suitable for multiple plant equipment and uses.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of thread connection sectional view with locking functions of this utility model.
Fig. 2 is a kind of thread connection bolt sectional view with locking functions of this utility model.
Fig. 3 is a kind of thread connection working state schematic representation with locking functions of this utility model.
Detailed description of the invention
Details and the working condition of the concrete equipment that foundation the utility model proposes is described in detail below in conjunction with accompanying drawing.
A kind of thread connection with locking functions, mainly includes bolt 1, steel ball 3, holding screw 2.Bolt 1 is hollow structure, and inside has screwed hole and taper hole, bolt 1 head to have radially gap, and it is internal that steel ball 3 is arranged on bolt 1, and it is internal that holding screw 2 is arranged on bolt 1, and contacts with steel ball 3.
Before use, the taper hole position within bolt 1 put into by steel ball 3, and holding screw 2 is arranged on bolt 1 internal whorl hole site, and does not have extruding force between steel ball 3.
When two machine components 4,5 are fastened by needs, it is first according to the occupation mode of conventional bolt, two machineries 04,5 are fastened, then undertaken tightening by holding screw 2.
In the process tightening holding screw 2, holding screw 2 promotes steel ball 3 to travel forward in bolt 1 taper hole, and extrude taper hole by steel ball 3, owing to bolt 1 head has radially gap, therefore, bolt 1 head actually can outwards expand slightly, thus the pressure added between king-bolt 1 head and connected piece 5, finally make to screw and mutually compress between screw thread, reach locking purpose.
Claims (2)
1. a thread connection with locking functions, mainly include bolt (1), steel ball (3), holding screw (2), it is characterized in that: bolt (1) is hollow structure, there are screwed hole and taper hole in inside, bolt (1) head has radially gap, it is internal that steel ball (3) is arranged on bolt (1), and it is internal that holding screw (2) is arranged on bolt (1), and contacts with steel ball (3).
