Description
Technical field
The present invention relates to a kind of easy-to-dismount thread locking structures more particularly to a kind of locking thread to move structure.
Background technique
It is all provided with corresponding connection component in the end of engineering field, many cables (such as signal transmssion line), so as to
It concatenates, disconnect in cable and the plug of device and more cables are mutual, in order to guarantee connective stability when connection,
Threaded connection is generallyd use between connection component and corresponding connecting element, in order to prevent thread looseness, it is necessary in screw thread week
Corresponding anti-loose structure is set on the structural body enclosed, and structure is complicated mostly for existing anti-loose structure, leads to connection component
Higher cost.
Summary of the invention
For the problems in background technique, the invention proposes a kind of locking threads to move structure, and innovation is: the spiral shell
Line anti-loose structure is made of connector one, connector sleeve, connector two and elastic ring；Right section of the connector one is denoted as connection
End, connecting pin are cylindrical structure body, are provided with external screw thread on the outer peripheral surface of the connecting pin, set on the end face of the connecting pin
It is equipped with annular groove, in a ring groove, the outer end face of elastic ring is raised from the end face of connecting pin for the elastic ring setting；The company
It is provided with variable cross-section through-hole in female connector, left section of formation thread segment of the variable cross-section through-hole is arranged on the inner wall of the thread segment
Have and is arranged on the inner wall of linkage section with the matched internal screw thread of the external screw thread, right section of formation linkage section of the variable cross-section through-hole
Restraining position ring block, the internal diameter of stop collar are less than the internal diameter of thread segment；The middle part of the connector two is provided with matched with stop collar
Limiting slot, the axial length of the limiting slot are greater than the axial length of stop collar, the section shape on the left of two upper limit position groove of connector
At connector, the axial length of connector is less than the axial length of the thread segment, and the diameter of connector is less than thread segment internal diameter,
The diameter of connector is greater than stop collar internal diameter；The connector is socketed in connector sleeve, and the stop collar is located in limiting slot, even
Connector is located in thread segment, and the connecting pin of connector one is threadedly coupled with the thread segment of connector sleeve；End face and company when connecting pin
When the end face of connector contacts and the left side wall of limiting slot is pushed against on the left side of stop collar, connector one and connector two are locked
Tightly.
In use, first independent rotation connector sleeve, makes connector one gradually in precession connector sleeve, connector is also in stop collar
It is moved under promotion to the direction close to connecting pin, after connecting end surface and elastic ring contacts, continues to rotate with connector sleeve,
Elastic ring is gradually connected end surface and squeezes, under the restoring force effect of elastic ring, thread left side on external screw thread with it is interior
Face contact (contact portion of two kinds of threads is denoted as contact surface) on the right side of thread on screw thread, meanwhile, the left side wall of limiting slot
It is pushed against on the left side of stop collar (as shown in Figure 1), continues to rotate with connector sleeve, the restoring force of elastic ring also gradually increases
Greatly, so that the stress acted on the contact surface be made also to be gradually increased, manpower just needs that connection can just be made to pack into one with bigger power
Step rotation, when elastic ring restoring force increase to a certain extent after, manpower just can not turn connector sleeve, at this point, to connector
Two apply stress (as shown in Figure 2) to the left, make connector elasticity of compression circle to the left, so that the restoring force of elastic ring be made not remake
With on the contact surface, the thread on thread and internal screw thread on external screw thread can just relatively rotate again, at this point, being further continued for turn
Connector sleeve is pushed against the left side wall of limiting slot again on the left side of stop collar, then looses one's grip, and at this moment, elastic ring will incite somebody to action
Bigger restoring force is applied on contact surface, thus make connector one and connector two be firmly locked in together, not to
In the case that connector two applies stress to the left, connector one and connector two can not loosen；It, only need to be when disassembly
While applying stress to the left to connector two, connector sleeve is reversely rotated, connector sleeve can be screwed off from connector one, be torn open
It unloads easy to operate；
It is integrated to practical application, one kind can be obtained by following scheme and have the dynamic function of locking thread and disassembly very easily
Cable connecting component: being provided with first axis through-hole on the connector one, the internal diameter of the annular groove is logical greater than first axis
The diameter in hole, annular groove and first axis through-hole are coaxial；The second axially extending bore, one He of connector are provided on the connector two
When connector two is locked, first axis through-hole and the connection of the second axially extending bore.
The method have the benefit that: a kind of dynamic structure of locking thread is provided, which moves the lock of structure
Tight operation and disassembling section are quite convenient to, and structure is simple, is used on cable connecting component, when both can guarantee connection
Connectivity robustness, and can very easily dismantle.
Detailed description of the invention
Fig. 1, structural schematic diagram one of the invention；
Fig. 2, structural schematic diagram two of the invention (arrow as shown in the figure is the stress to the left applied to connector two)；
Title corresponding to each label is respectively as follows: one A of connector, connector sleeve B, two C of connector, elastic ring D in figure.
Specific embodiment
A kind of locking thread moves structure, and innovation is: the locking thread move structure by one A of connector, connector sleeve B,
