Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.The description only actually at least one exemplary embodiment is illustrative to be never used as to this practicality below
New and its application or any restrictions used.Based on the embodiment in the utility model, those of ordinary skill in the art are not having
All other embodiments obtained under the premise of creative work are made, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model embodiment provides a kind of latch assembly.The latch assembly includes:Nut 10 and tight
Admittedly cover 20.Wherein, nut 10 has the first threaded hole, and the first threaded hole is used to be threadedly coupled with connector, the appearance of nut 10
Face is additionally provided with screw thread.There is adapter sleeve 20 ladder to be configured the second threaded hole and the 3rd threaded hole, and the second threaded hole is close to spiral shell
Mother 10 is set, and the second threaded hole and the threaded connection of 10 outer surface of nut, the 3rd threaded hole are threadedly coupled with connector.Cause
This, it can be seen that the processing technology of the latch assembly is simple, and effectively reduces production cost.
In the present embodiment, nut 10 is made to process screw thread on existing locking nut portlet outer surface, and
Nut 10 is played the role of being the same with locking nut of the prior art.Since locking nut in the prior art is in equipment
Easy loose or dislocation in longtime running, therefore increased adapter sleeve 20 plays locking locking screw in the prior art in the present embodiment
Female effect.By the structure design of adapter sleeve 20 it is recognised that adapter sleeve 20 is carried out by the 3rd threaded hole and equipment connector
It is threadedly coupled, meanwhile, adapter sleeve 20 is threadedly coupled further through the second threaded hole with nut 10.Through such a connection manner
So that adapter sleeve 20 plays the technique effect of locking nut 10, so as to prevent nut 10 from coming off and damaging in equipment longtime running
It is bad.Therefore, the latch assembly in the present embodiment be not only simple in structure, cost it is low, and can efficiently solve and lock in the prior art
The problem of tight nut loosening.
Specifically, in order to make adapter sleeve 20 preferably reach the effect of locking, preferably adapter sleeve 20 is arranged in band
The inside tapered thread set of cone, can so make the engagement central diameter of the tight nut of lock piston and connector screw thread change, so as to make
Locking nut locking on the piston rod, has achieveed the purpose that locking, so as to extend the service life of nut.
When the angle too small of inside tapered thread set, locking effect will be caused not ideal enough;When the angle mistake of inside tapered thread set
When big, it will lead to not smoothly be connected with connector.Therefore, when the angle of inside tapered thread set changes, locking can be caused to imitate
Fruit is different.Therefore, after can be by development test repeatedly, inside tapered thread angle value can be arranged in a zone of reasonableness,
So that the locking effect of the latch assembly reaches optimal.In the present embodiment, when processing adapter sleeve 20, by the 3rd screw thread
The diameter in hole is locked so as to adapter sleeve 20 and connected by being become larger close to the second threaded hole to the direction away from the second threaded hole
Part.
Specifically, in order to make latch assembly reach more preferable locking effect, the loosening of adapter sleeve 20 is prevented, in the locking group
Anti-looseness mechanism is additionally provided with the adapter sleeve 20 of part.Anti-looseness mechanism in the present embodiment includes limit hole and locating part
30.Wherein, limit hole is arranged at the side of adapter sleeve 20.Locating part 30 is arranged on limit hole with the connection mode of threaded connection
It is interior, it can be limited between adapter sleeve 20 and nut 10 by the connection between locating part 30 and limit hole or adapter sleeve 20 is with being connected
Relative position between part, so as to be better protected from the loosening of latch assembly and come off.
In this embodiment, it is preferred that locating part 30 is designed as jackscrew, and jackscrew is arranged in limit hole.Pass through top
The connection of silk and limit hole screw thread, can fix the relative position between adapter sleeve 20 and nut 10.Further, it is also possible to by changing
Become position of the locating part 30 on adapter sleeve 20 so that locating part 30 is used for fixing the opposite position between adapter sleeve 20 and connector
Put.
Specifically, adapter sleeve 20 has multiple side walls, and multiple side walls are with the center symmetric setting of adapter sleeve 20.In this implementation
Adapter sleeve 20 in example may be configured as hex bolts, thus limit hole can be arbitrarily arranged on to any one side of adapter sleeve 20
On face, it may also be arranged on multiple sides, to strengthen anti-loosening effect.
Correspondingly, nut 10 is disposed with the first nut segment and the second nut segment in the axial direction, the second nut segment
Screw thread is provided with outer surface, adapter sleeve 20 is connected with the second nut segment.Nut 10 in the present embodiment is improved locking
Nut, and in order to preferably reach fastening effect, the present embodiment also add adapter sleeve 20.Adapter sleeve 20 and the second of nut 10
Nut segment is threadedly coupled, and plays fastening effect.
Specifically, set and have the gap in the second nut segment of nut 10, the axis of the setting direction in gap and the second nut segment
Line direction is parallel.By setting gap in the axial direction in the second nut segment, can 20 and second nut segment of adapter sleeve into
During row thread fitting so that engagement central diameter changes with actual conditions, ensures the engagement effect of screw thread, so as to prevent nut
10 loosen, and then are more advantageous to locking effect.
Specifically, in order to preferably make 20 locking nut 10 of adapter sleeve, preferably it is provided with the second nut segment a plurality of
Gap, and a plurality of gap is set with the axisymmetrical of the second nut segment, to ensure overall engagement effect.
Specifically, nut 10 is made of chromansil material.Locking nut of the prior art uses chromansil material more
Material, chromansil material have very high intensity and toughness, it may have stronger impact resistance.Therefore, above-mentioned implementation is being used
In example after the latch assembly with adapter sleeve 20 and locating part 30 that provides, it can ensure that nut 10 is hardly damaged and locking effect
It is good.
As shown in Fig. 2, in another embodiment of the utility model, there is provided a kind of compressor, including piston 40, piston rod
50 and latch assembly, it is characterised in that latch assembly is the latch assembly provided in above-described embodiment.In the work of the compressor
During work, piston rod 50 is threaded through on piston 40, and the nut 10 of latch assembly is carried out by the first threaded hole and piston rod 50
It is threadedly coupled, the 3rd threaded hole of adapter sleeve 20 is threadedly coupled with piston rod 50, and further limits nut by locating part 30
10 change in location, so as to reach lasting anti-loosening effect.
Found by repetition test, using latch assembly compressor loads operation 16000 it is small when after, the latch assembly is still
Good locking property is so kept, nut 10 is not also loosened or damaged.Therefore, using the latch assembly in the present embodiment not only
The scene actual use performance of locking nut is met, and extends the service life of a whole set of compressor set.Therefore, this implementation
Latch assembly in example has wide practical use in the maintenance of Large Piston compressor and installation process.
