Description
Technical field
The utility model is related to a kind of anti-loose structures of fast cylinder locking nut.
Background technology
Fast cylinder is used widely in injection molding machine, and the piston rod of fast cylinder is fastened by locking nut, due to piston
Bar frequently moves back and forth, and especially in high speed impact, can cause larger moment impact, can inevitably cause locking screw
Female loosening, directly affects the normal work of fast cylinder.Therefore, generally can all be arranged when designing the locking nut of fast cylinder anti-
Loose structure, still, the anti-loosing effect of anti-loose structure is general in the prior art, and after long-term use, locking nut still can occur
Loose phenomenon not only affects production efficiency, and reduces the service life of fast cylinder.
Utility model content
It is reasonable for structure the purpose of this utility model is to provide a kind of anti-loose structure of fast cylinder locking nut, effectively
It avoids locking nut and loose phenomenon occurs.
To achieve the above object, the technical solution of the utility model is to design a kind of anti-untwisting of fast cylinder locking nut
Structure, including with externally threaded piston rod, and respectively by screw-thread fit connection locking nut on the piston rod and locking
Nut;The locking nut is equipped with several threaded holes on the end face towards stop nut, and several threaded holes are around locking nut
Center pore size distribution;There are deformation gaps, the stop nut to be equipped with and several spiral shells between the stop nut and locking nut
Several through-holes, each through-hole are equipped with screw to pit with corresponding threaded hole correspondingly, keep stop nut and locking nut solid
Fixed connection;It is radially provided with groove in the outside wall surface of the stop nut, which communicates with the centre bore of stop nut, described anti-
It is additionally provided with the screw hole of through-going recess on loose nut, screw is installed in the screw hole.
Preferably, the quantity of the threaded hole is 3, corresponding, and the quantity of through-hole is 3.
Preferably, the quantity of the screw hole is 1, and 1 screw hole and 3 through-holes are equal around the centre bore of stop nut
Even distribution.
Preferably, the shape of the locking nut is rectangle, and the shape of the stop nut is circle.
The advantages of the utility model and advantageous effect are:Since there are deformation joints between stop nut and locking nut
Gap, when tightening through-hole with the screw in corresponding threaded hole, stop nut and locking nut are drawn close slightly, make stop nut and lock
The screw thread of tight nut is pressed on the correspondence screw thread of piston rod, considerably increases the frictional force between screw thread, you can reach locking
Purpose.In addition, being also provided with the screw hole of through-going recess on stop nut, when being screwed into screw in screw hole, groove becomes
Shape makes the screw thread of stop nut be pressed on again on the correspondence screw thread of piston rod, further improves the locking property of stop nut
Can, in this way by the different thread segments of clamping piston bar, improve locking reliability.Because the anti-loosening property of stop nut is high,
And stop nut is fixedly connected with locking nut, this prevents locking nuts to rotate, to avoid locking nut that pine occurs
Dynamic phenomenon.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of locking nut in the utility model.
Fig. 3 is the schematic diagram of stop nut in the utility model.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
The utility model specific implementation technical solution be:
As shown in Figure 1, Figure 2 and Figure 3, a kind of anti-loose structure of fast cylinder locking nut, including with externally threaded piston
Bar 1, and the locking nut 2 and stop nut 3 that are connected to respectively by screw-thread fit on piston rod 1;The locking nut 2 exists
End face towards stop nut 3 is equipped with several threaded holes 4, which is distributed around the centre bore 5 of locking nut 2;Institute
It states there are deformation gap 6 between stop nut 3 and locking nut 2, which is equipped with a pair of with several threaded holes 4 one
Several through-holes 7 answered, each through-hole 7 with screw 8 is installed in corresponding threaded hole 4, so that stop nut 3 and locking nut 2 is fixed and connect
It connects;Groove 9 is radially provided in the outside wall surface of the stop nut 3, which communicates with the centre bore 10 of stop nut 3, described
It is additionally provided with the screw hole 11 of through-going recess 9 on stop nut 3, screw 12 is installed in the screw hole 11.
Also, the quantity of above-mentioned threaded hole 4 is 3, corresponding, and the quantity of through-hole 7 is 3;The quantity of above-mentioned screw hole 11
It it is 1,1 screw hole 11 and 3 through-holes 7 are uniformly distributed around the centre bore 10 of stop nut 3.
In addition, the shape of above-mentioned locking nut 2 is rectangle, the shape of above-mentioned stop nut 3 is circle.
When installation, screw 8 is passed through and through-hole 7 and is screwed into corresponding threaded hole 4, due to stop nut 3 and locking nut 2 it
Between there are deformation gap 6, therefore stop nut 3 and locking nut 2 will be drawn close slightly when tightening screw 8, are made stop nut 3 and locked
The screw thread of tight nut 2 is pressed on the correspondence screw thread of piston rod 1, considerably increases the frictional force between screw thread, you can reach anti-
The purpose of pine.Then screw 12 is screwed into screw hole 11, groove 9 deforms when tightening screw 12, makes the screw thread of stop nut 3
It is pressed on again on the correspondence screw thread of piston rod 1, further improves the anti-loosening property of stop nut 3, lived in this way by compressing
The different thread segments of stopper rod 1, improve locking reliability.Because the anti-loosening property of stop nut 3 is high, and stop nut 3 and lock
Tight nut 2 is fixedly connected, and this prevents locking nuts 2 to rotate, to avoid locking nut 2 that loose phenomenon occurs.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
