Description

Anti-coupling shaft device

Technical field

The utility model relates to a kind of shaft device that connects, and more specifically says, it relates to a kind of anti-coupling shaft device.

Background technique

Power connects in the equipment operation often with suddenly stopping or reversing.At present prior art connect shaft device, if forward rotation, the joint can be maintained fixed, if but counter-rotating often get loose easily, rotating shaft is come off, cause equipment badly damaged, make production line be subjected to the influence of stopping.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple in structure, be easy to make, save cost, the convenient connection, can keep the fastening anti-coupling shaft device that becomes flexible of preventing.

The utility model is realized the technological scheme that purpose adopted.This anti-coupling shaft device, mainly comprise first and second, wherein first and second are by being threaded, joint first and second is provided with anchor ear, on first of close joint, be provided with first groove, be provided with second groove near on second of joint, the inwall of anchor ear is provided with first groove and is first boss that clamping cooperates, is second boss that clamping cooperates with second groove.

Described first is provided with first bevel phase, and second is provided with first bevel phase and is second bevel phase that cone match is connected.

First be provided with external thread section foremost, between the external thread section and first groove, be provided with first bevel phase, be provided with the internal thread segment that cooperates with external thread section at the end of second inner chamber.

Described anchor ear is provided with the fixed hole that is used for fixing connection.

Because adopt technique scheme, the anti-coupling shaft device that the utility model provides has following beneficial effect, and is simple in structure, reasonable in design, can effectively prevent to connect the loosening of axle, keep fastening.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified model and the equivalent in the scope of the present utility model that can be included in attached claims qualification.

Referring to Fig. 1-5, the anti-coupling shaft device of Jie Shaoing generally is used for the connection of rotatingshaft here, yet should know, the utility model also can be used for the connection of other device.Anti-coupling shaft device described herein mainly comprises first 1 and second 2, and wherein first 1 and second 2 is provided with anchor ear 3 by being threaded first 1 and second 2 joint, and anchor ear 3 is provided with the fixed hole 3-1 that is used for fixing connection.On first 1 of close joint, be provided with the first groove 1-3, be provided with the second groove 2-3 near on second 2 of joint, the inwall of anchor ear 3 is provided with the first groove 1-3 and is first boss 4 that clamping cooperates, is second boss 5 that clamping cooperates with the second groove 2-3.

First 1 be provided with external thread section 1-1 foremost, between the external thread section 1-1 and the first groove 1-3, be provided with first bevel phase 1-2, end at second 2 inner chamber is provided with the internal thread segment 2-1 that cooperates with external thread section 1-1, and second 2 is provided with first bevel phase 1-2 and is second bevel phase 2-2 that cone match is connected.

The utility model basic principle: screw in second 2 when first 1, after putting in place, put anchor ear 3 again, first boss 4 on the anchor ear 3 and second boss 5 are when mounted respectively over against going into the first groove 1-3 and the second groove 2-3,1 and second 2 on the axle of winning is fixed in the axial direction, again anchor ear 3 usefulness bolt are lived, so no matter how to rotatablely move, motion between first 1 and second 2 is always consistent, not can radially with axially on produce relative movement.
