Description
Technical field
It the utility model is related to a kind of sleeve, more particularly to a kind of magnetic sleeve.
Background technology
Sleeve is the instrument that can be all commonly used in people's routine work life, either in common flight-line maintenance also
Be building build installation process middle sleeve be all essential, ordinary cartridge is only equipped with the sleeve driver head of a model,
When in use, sometimes because sleeve size issue, after nut is turned on, nut can drop, and be not easy to staff's collection
Nut.
In the service work of power industry electrical equipment, for product such as transformer with large sealing class,
Dismounted sometimes for internal screw, for example change the low-pressure side sleeve pipe of transformer, it is necessary to it is low to open hand hole cover dismounting
Voltage lead wires terminal plate.During dismounting, nut is easy to fall into body interior, causes the consequences such as internal winding leads short circuit, ground connection, very
To whole transformer is burnt, so the nut to drop must be found, the work that cover etc. takes time and effort of draining the oil, hang thus is needed,
Generally require to be completed with more than ten people work of four or five days, waste huge manpower and materials.
In Chinese patent literature disclosed " a kind of sleeve for preventing that nut from coming off ", its notification number is
CN203210292U, the day for announcing are on 09 25th, 2013, and this application case discloses a kind of sleeve for preventing nut from coming off, including
Sleeve, the screw and its jackscrew run through is transversely provided with sleeve lateral wall；Screw and jackscrew are located at the middle and upper part of sleeve；Sleeve is six
Interior angle sleeve.This anti-nut comes off the use of specific purpose tool, has effectively prevented nut in upkeep operation and has dropped to transformer device
Hidden danger in body, improves operating efficiency, prevents the input unnecessary for repeating operation, reducing a large amount of manpower and materials, ensures inspection
Quality is repaiied, improves main transformer operational reliability, site examining and repairing uses the instrument, have received good effect.The practicality is new
The weak point of type is to need to tighten jackscrew manually, inconvenient for operation.
Utility model content
The utility model is in order to overcome deficiency of the prior art, there is provided a kind of magnetic sleeve for preventing that nut from coming off.
To achieve these goals, the utility model uses following technical scheme：
A kind of magnetic sleeve, including sleeve body and magnetic piece, sleeve body include nut end and and handle end, sleeve sheet
Body is provided with the cavity for being available for nut to be moved axially along sleeve body between nut end and handle end, and magnetic piece is arranged on institute
State in cavity, the through hole passed through for bolt is provided with magnetic piece, magnetic piece is connected by a spring with handle end, at spring
Magnetic piece is located at nut end when natural retracted position.Sleeve is directed at nut during use, nut is entered nut end, now spiral shell
Female magnetic force by magnetic piece attracts, and can avoiding sleeve, nut comes off in use, and nut progressively screws in the process of bolt
In, spring constantly compresses, and is finally completed the fastening work of nut, improves operating efficiency.
Preferably, the diameter of spring is more than the diameter of through hole on magnetic piece, i.e., when bolt passes through the through hole on magnetic piece
Spring housing is in the outside of bolt.
Preferably, being cased with accommodating member outside magnetic piece, the shape of the shape of accommodating member and the cavity is corresponding.Due to magnetic
Property plate shape processing difficulties, accommodating member and cavity are arranged outside magnetic piece to be coordinated, and facilitates the production of sleeve.
Preferably, the thickness of accommodating member is not less than 0.4mm.Due to space be present between nut and sleeve body cavity,
Nut when screwing in bolt, nut can tilt fill it is askew result in the need for by nut screw out reinstall.When the thickness foot of accommodating member
When enough big, although because space between accommodating member and sleeve body cavity be present, accommodating member axially also can only produce along sleeve pipe
Raw small inclination, therefore the plane that accommodating member and nut are contacted also only produces small inclination, because nut is by magnetic
Piece, which adsorbs, is close to accommodating member, so nut only produces small skew, and this small inclination will not cause filling for nut askew.
Therefore, the utility model has the advantages that：（1）Prevent nut from coming off；（2）It is askew to prevent that nut from filling.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of the utility model A-A sections.
In figure：1st, sleeve body, 2, nut end, 3, handle end, 4, magnetic piece, 5, spring, 6, accommodating member.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made more specifically
It is bright.
As shown in Figure 1 and Figure 2, a kind of magnetic sleeve, including sleeve body 1 and magnetic piece 4, sleeve body 1 include nut end
2 and with handle end 3, sleeve body 1 is provided between nut end 2 and handle end 3 is available for nut axially to be moved along sleeve body 1
Dynamic cavity, cavity cross section are shaped as regular hexagon, and magnetic piece 4 is arranged in cavity, is provided with magnetic piece 4 for bolt
The through hole passed through, magnetic piece 4 are connected by a spring 5 and handle end 3, magnetic piece 4 when spring 5 is in nature retracted position
In nut end 1.The diameter of spring 5 is more than the diameter of through hole on magnetic piece 2, i.e., bolt is through described in during through hole on magnetic piece 4
Spring 5 is enclosed on the outside of bolt.Accommodating member 6 is cased with outside magnetic piece 4, the shape of accommodating member 6 and the shape of cavity are corresponding.It is accommodating
The thickness of part 6 is 0.5mm.
