Description
Technical field
The utility model relates to the mechanical designing technique field, is specifically related to a kind of screw-threaded coupling mechanism with anti-error plug-in mounting.
Background technique
In mechanical processing industry, being threaded is one of Placement of using always.Especially in the communication apparatus of the communications field, be threaded and adopted widely especially.
Yet existing be threaded normally is meshing with each other and reaches interconnective purpose by being arranged on internal thread on the connected element and outside thread.Though this Placement is with low cost, its reliability is poor, the situation that screw thread comes off occurs through regular meeting.
In addition, in many instances, do not allow between the connected element to misplug.And existing linkage structure does not obviously possess and prevents to misplug the function that connects.
For solving the aforementioned problems in the prior, the utility model provides a kind of new solution.
Summary of the invention
The technical problems to be solved in the utility model is: the deficiency that overcomes common screw connection structure, a kind of screw-threaded coupling mechanism with anti-error plug-in mounting is provided, this screw-threaded coupling mechanism with anti-error plug-in mounting has advantages such as simple in structure, with low cost, easy to use, not only can effectively prevent to be threaded comes off, and can also prevent the dress that misplugs between the connected element simultaneously effectively.
To achieve the above object of the invention, the technological scheme that the utility model adopted is: a kind of screw-threaded coupling mechanism with anti-error plug-in mounting is provided, it is characterized in that: comprise
One encoding block is arranged on the connected element of below; Described encoding block is a hollow structure, and upper half part is hexagonal structure, the rounded structure of lower half portion; Some limits are provided with a breach in the Hexagon of upper half part of described encoding block; Described encoding block is provided with the flexible clamping ring that is made of at least three lobe elastic claws bottom;
One sleeve, sleeve turn over riveting below connected element on; Described sleeve is hollow cylindrical structures, and upper cartridge is provided with a contraction flow region that is used for the mutual clamping of clamping ring of encoding block;
One block or outlet box ear, described block or outlet box ear are arranged on the sleeve below, are used for the sleeve encapsulation fixing; Be provided with a tapped hole with corresponding position, the medial axis of sleeve and encoding block in described block or the outlet box ear;
The tapped hole that one lock screw, described lock screw pass in block or the outlet box ear is screwed in the encoding block;
One guide pin is arranged on the connected element of top, described guide pin front end hollow, in be provided with the interior threaded hole that is threaded with lock screw, the sidewall of guide pin be provided with one with encoding block on the projection that mates mutually of breach.
In sum, the screw-threaded coupling mechanism with anti-error plug-in mounting provided by the utility model has following advantage:
1, simple in structure, with low cost, easy to use;
2, can effectively prevent to be threaded and come off;
3, can prevent the dress that misplugs between the connected element effectively.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be described in detail:
As shown in the figure, this is characterized in that with the screw-threaded coupling mechanism of anti-error plug-in mounting: comprise an encoding block 1, be arranged on the connected element of below; Described encoding block 1 is a hollow structure, and upper half part is hexagonal structure, the rounded structure of lower half portion; Some limits are provided with a breach 6 in the Hexagon of upper half part of described encoding block 1; Described encoding block 1 is provided with the flexible clamping ring that is made of at least three lobe elastic claws bottom; One sleeve 2, sleeve 2 turn over riveting below connected element on; Described sleeve 2 is hollow cylindrical structures, and sleeve 2 tops are provided with a contraction flow region that is used for the mutual clamping of clamping ring of encoding block 1; One block 4 or outlet box ear 8, described block 4 or outlet box ear 8 are arranged on sleeve 2 belows, are used for sleeve 2 encapsulation fixing; Corresponding position, medial axis with sleeve 2 and encoding block 1 in described block 4 or the outlet box ear 8 is provided with a tapped hole; The tapped hole that one lock screw 3, described lock screw 3 pass in block 4 or the outlet box ear 8 is screwed in the encoding block 1; One guide pin 5 is arranged on the connected element of top, described guide pin 5 front end hollows, in be provided with the interior threaded hole that is threaded with lock screw 3, the sidewall of guide pin 5 be provided with one with encoding block 1 on the projection 7 that mates mutually of breach.
As shown in Figure 3 and Figure 4, the outer edge of described outlet box ear 8 is provided with a portion that is bent upwards that is used for further fixed muffle 2 and encoding block 1.
The shell of connector is provided with sector that the hexagonal structure with encoding block mates mutually or the Hexagon groove location with control encoding block direction of index.By being set, the Hexagon groove can realize that 36 kinds cooperate the location.Certainly, also can adopt quadrilateral, pentagon, Heptagon to wait and realize anti-error plug-in mounting function.
When needs are pulled down encoding block, lock screw can be screwed off, this moment, the elastic claw of encoding block lower end did not shrink automatically owing to there is the filling tensioning of lock screw, so encoding block directly can be extracted out from sleeve.
