The technical solution of the utility model is: a kind of multifunctional nut locking device, the increasing of the conversion head that this device is connected successively by coaxial, zone axis through hole keep away a ring, zone axis through hole connecting plate and pulloverly to form, described conversion head is provided with the conversion connecting hole for connecting torsion member, described pullover on form the nut trepan matched with nut outer wall face.
The utility model, on the basis of technique scheme, also comprises following preferred version:
Described nut trepan is regular polygon hole, more preferably regular hexagon hole.
Described conversion head, increase and keep away a ring, connecting plate and be pulloverly above all shaped with tapped through hole, and change head, increase keep away a ring, connecting plate and pullover be fixed together by wearing the screw rod be connected in these tapped through holes.
Described conversion head is circular plate type structure, described in increase that to keep away a ring be columnar structured, described connecting plate is regular hexagon structure, the cirque structure of described pullover to be its central shaft hole be described nut trepan.
The cross section of described conversion connecting hole is square.
Described nut trepan, conversion connecting hole and described in increase and keep away axis through bore coaxial line on a ring and connecting plate and arrange.
The utility model has the advantages that:
1) this device is formed by connecting by screw rod mate with threaded holes by four parts of split-type structural, the dismounting in each portion and change very convenient.
2) this device is simple to operate, and clamping is easy, and efficiency is high.
3) each parts of this device have all carried out surface treatment, thus can not scratch nut surface when ensureing assembling.
4) this device is formed by four split type assembling parts, but not a monolithic construction, during production, four parts are independently processed, but not whole locking device time processing is shaping, there is not the one-time formed difficulty problem of machined.
5) when assembling nut, the outboard end of threaded sleeve (or screw rod) connecting plate can be penetrated and increase keep away a ring axis through bore in, thus efficiently solve threaded sleeve outboard end keep away a problem.Meet the requirement keeping away position and torque value simultaneously, only need removable parts parts (be generally pullover or increase and keep away a ring) that the different part locking required can be met.The function of torque screwdriver is magnified by this device, for research one, torque screwdriver is met multiple irregular part torque requiremnt simultaneously and plays a vital step.

Fig. 2 is the exploded view of this multifunctional nut locking device of the utility model embodiment;
Fig. 3 is the stereogram of this multifunctional nut locking device of the utility model embodiment;
Fig. 4 is the front view of this multifunctional nut locking device of the utility model embodiment;
Wherein: 1-conversion head, 1a-changes connecting hole, and 2-increases and keeps away a ring, 3-connecting plate, and 4-is pullover, 4a-nut trepan, 5-tapped through hole, 6-nut, 7-threaded sleeve.
Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
With reference to shown in Fig. 2, Fig. 3 and Fig. 4, this multifunctional nut locking device that the present embodiment provides, be connected successively by coaxial conversion head 1, zone axis through hole increase keep away a ring 2, the connecting plate 3 and pullover 4 of zone axis through hole forms.Wherein, conversion head 1 being provided with the conversion connecting hole 1a for connecting torsion member (being generally torque screwdriver), on pullover 4, forming the nut trepan 4a matched with the outside wall surface of nut 6.
With reference to shown in Fig. 1, now the method that the cable seal be made up of nut 6 and threaded sleeve 7 is locked on regulator cubicle is simply described below by this multifunctional nut locking device of use the utility model:
The end of thread of threaded sleeve 7 is outwards passed from cabinet inside, again nut 6 is aimed at the end of thread of threaded sleeve 7, nut trepan 4a on pullover 4 to be enclosed within nut 6 thus to make the two relatively fixing at circumferencial direction, afterwards the connector of torque screwdriver to be inserted in the conversion connecting hole 1a of conversion head 1 thus to make that the two is also relatively fixing at circumferencial direction, pull torsion member make this nut locking device drive nut 6 around threaded sleeve 7 rotate (outboard end of threaded sleeve 7 penetrate connecting plate 3 and increase keep away a ring 2 axis through bore in, thus efficiently solve threaded sleeve 7 outboard end keep away a problem), until the medial extremity of threaded sleeve 7 presses regulator cubicle inwall, and nut 6 tightly suppresses regulator cubicle outer wall, just complete cable seal in Fig. 1 and be locked at being locked on regulator cubicle.Lock and backwardly outer extracted this locking device.
But in practical operation, people adopt the method for free-hand locking to be fixed on regulator cubicle by cable seal usually, the mode of this free-hand locking cannot ensure torsion.If the locking sleeve by existing routine completes being locked of cable seal, torsion and the requirement keeping away position can not be met simultaneously.
Consider that the outside wall surface of nut 6 mostly is regular polygon, therefore the 4a of nut trepan described in the present embodiment adopts regular polygon pore structure.And wherein positive hex nut is the most common, therefore in this example, nut trepan 4a is regular hexagon hole.
Consider that the connector of most of torque screwdriver is that very cross section is foursquare rod-like structure, thus change described in the present embodiment connecting hole 1a adopt cross section be foursquare square opening structure.
And the axis through bore coaxial line that described nut trepan 4a, conversion connecting hole 1a and increasing keep away on a ring 2 and connecting plate 3 is arranged, to make this device more convenient to use.
In the present embodiment, described conversion head 1, increase keep away a ring 2, concrete connected mode between connecting plate 3 and pullover 4 can refer to shown in Fig. 2: conversion head 1, increase to keep away on a ring 2, connecting plate 3 and pullover 4 and be all shaped with tapped through hole 5, described change 1, increase keep away a ring 2, connecting plate 3 and pullover 4 is fixed together by wearing the screw rod be connected in these tapped through holes 5.The locking device of this structure is very facilitate in dismounting and replacing parts.
Described conversion head 1, increase keep away a ring 2, connecting plate 3 and pullover 4 adopts split-type structurals, a but not monolithic construction, during making, four independently process, but not whole locking device time processing is shaping, solve the one-time formed difficulty problem of machined.
Described conversion head 1, increase keep away a ring 2, connecting plate 3 and pullover 4 concrete shape do not limit.Consider stress performance and the difficulty of processing problem of each parts, in this example, each parts have employed following shape, and conversion head 1 is circular plate type structure, increase and keep away a ring 2 for columnar structured, connecting plate 3 is regular hexagon structure, and pullover 4 is its central shaft holes is the cirque structure of described nut trepan 4a.As Fig. 2.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
