Bolt head, bolt head use special cylindrical bolt head, the installation of all size size can be adapted to coordinate.Such bolt
Although head shapes compared with prior art in square bolt head have a larger improvement, cylindrical bolt head is outstanding when mounted
It is inconvenient, it is necessary to is installed using special installation tool.According to the mode being manually mounted directly, because finger is touched
The lifting surface area of cylindrical side is smaller so that adds difficulty to installment work, has much room for improvement.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of T-bolt of convenient disassembly,
The T-bolt of this convenient disassembly can not only be installed using installation tool, manually be mounted directly also more convenient.
To achieve the above object, the utility model provides following technical scheme：
A kind of T-bolt of convenient disassembly, including bolt head and shank of bolt, the bolt head radially protruding is in the bolt
Bar one end, the bolt head include cylinder and the projection in the cylindrical sides radially protruding, and described two projections are in institute
State cylindrical sides radial symmetric, one end of the shank of bolt and the bolt head homonymy is axially projecting adapter.
By using above-mentioned technical proposal, sunk part that cylinder is formed with projection is just being used on putting for forefinger and middle finger
Put, be easy to human hand bolt head to exerting a force and controlling shank of bolt, to bad control bolt head when effectively avoiding manual operation
Problem.The setting of adapter, it can be connected with other instruments such as electric drills, improve the practicality of the T-bolt of convenient disassembly.
Further, the shank of bolt includes threaded portion and polished rod portion, and the bolt head is located at the polished rod portion away from spiral shell
The one end in line portion.
Further, 1.5 times of the flighted length more than the polished rod minister degree.
By using above-mentioned technical proposal, the mechanical strength for being designed to improve bolt of partial threads, bear bolt
Bigger moment of torsion.
Further, the polished rod portion and the junction of the bolt head are provided with chamfering.
By using above-mentioned technical proposal, the work being subject in polished rod portion and the dispersible junction of chamfering of bolt head junction
Firmly, the structural strength of junction is improved.
Further, the bottom surface of the threaded portion is provided with flat recess.
By using above-mentioned technical proposal, after the T-bolt of convenient disassembly is threadedly coupled with other workpiece, if wanting to remove
The T-bolt of convenient disassembly, it can not only be removed by way of rotating bolt, also can be by straight screwdriver from tearing open
The bottom for filling convenient T-bolt is removed, and improves the detachability of the T-bolt of convenient disassembly, easily facilitates assembling.
Further, the adapter is cylindrical.
By using above-mentioned technical proposal, it can be connected by adapter with other instruments such as electric drills, improve dismounting side
Just the practicality of T-bolt.
In summary, the sunk part that cylinder is formed with projection is just being used on the placement of forefinger and middle finger, is easy to human hand
Bolt head is to exerting a force and controlling shank of bolt, to bad the problem of controlling bolt head when effectively avoiding manual operation；Adapter
Setting, can be connected with other instruments such as electric drills, improve the practicality of the T-bolt of convenient disassembly；If the T of convenient disassembly
When type bolt thread is connected on through hole, it can be dismantled by the flat recess of straight screwdriver rotating threaded rod, improve and tear open
The detachability of convenient T-bolt is filled, is easy to dismount.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, a kind of T-bolt of convenient disassembly, including bolt head 1 and shank of bolt 2.Shank of bolt 2 is in cylinder,
It can install and coordinate from a variety of different workpiece.Shank of bolt 2 includes polished rod portion 21 and threaded portion 22, and the length of threaded portion 22 is big
In 1.5 times of the length in polished rod portion 21.The mechanical strength for being designed to improve bolt of partial threads, bears bolt bigger
Moment of torsion.
As shown in Fig. 2 bolt head 1 is composite unit structure, it is to be set by cylinder 11 and in cylindrical sides radial symmetric
The three-dimensional shape that combines of two projections 12.One bottom surface of cylinder 11 is fixedly connected with polished rod portion 21, and cylinder
11 center of circle overlaps with the center of circle in polished rod portion 21.Chamfering 3 is provided between cylinder 11 and polished rod portion 21, such connection can carry
The structural strength of high product.When being manually mounted directly the T-bolt of convenient disassembly, generally use thumb fixing bolt is first
Side, forefinger and middle finger are connected to opposite side, if bolt head is circular or regular polygon, hold such bolt head, shank of bolt holds
Easily tilted on the internal thread of workpiece, shank of bolt external screw thread easily misplaces with internal thread, causes bolt installation to shift.And this
The T-bolt of convenient disassembly in embodiment, need not specially find forced position accurately in artificial be mounted directly, cylinder 11 with it is convex
The sunk part that block 12 is formed just is being used on the placement of forefinger and middle finger, is easy to human hand bolt head 1 to exerting a force and controlling shank of bolt
2, to bad the problem of controlling bolt head 1 when effectively avoiding manual operation.The both sides of projection 12 are provided with the circular arc of indent
Face.
As shown in figure 1, side of the bolt head 1 away from shank of bolt 2 is fixedly connected with adapter 4.Adapter 4 is cylindrical.
Shank of bolt 2 is threadedly coupled with other workpiece, now adapter 4 is located at outer workpiece, by adapter 4 can with electric drill etc. its
He connects instrument, improves the practicality of the T-bolt of convenient disassembly.
As shown in Fig. 2 the one end of threaded portion 22 away from polished rod portion 21 is provided with flat recess 5.In the T-bolt of convenient disassembly
, can not only be by way of rotating bolt first 1 if wanting to remove the T-bolt of convenient disassembly after being threadedly coupled with other workpiece
Removed, can also be removed by straight screwdriver from the bottom of the T-bolt of convenient disassembly, improve convenient disassembly
T-bolt detachability, easily facilitate dismounting.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, it is all in this practicality
Within new design concept, any modification, equivalent substitution and improvements made etc., protection of the present utility model should be included in
