Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached in the embodiment of the present invention
Figure, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only this
Invention a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art exist
The every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
A kind of telescopic bolt as shown in Figure 1 to Figure 3 adjusts tool, is mainly used for the adjustment that bolt is tightened, dismantled
Tool, the tool include the cross bar 1 being laterally arranged, vertically arranged main body outer bar 2 and main body interior bar 3 and lower part end 4.
Wherein, main body outer bar 2 is hollow cylindrical, and main body interior bar 3 is solid cylindrical, and 3 activity of main body interior bar is nested in main body outer bar 2
Portion, and whole and 3 inner transverse of main body interior bar is clamped, it cannot 2 inside of bar individually rotation outside the main body；Main body interior bar 3 can be opposite
In main body outer bar 2 in vertical direction activity, axial-movement can be done along the inside of main body outer bar 2, to realize stretching for entire tool
Long and shortening.It can know, 3 shape of main body interior bar matches with the interior shape of main body outer bar 2, main body outer bar 2 and main
The shape of internal bar 3 be not limited to it is single cylindric, during production and work, in order to meet specific standard and torque
It needs, the inside of main body outer bar 2 can be polygon-prism body.
The interior diameter of 2 bottom of main body outer bar is slightly larger than the overall diameter of main body interior bar 3, because torque transmission is by interior external key
It realizes, under normal circumstances It is not necessary to which axial restraint can be realized when contacting in contact, the two both in use.When main body interior bar
3 to minimum, at this time the 3 top contact of 2 bottom of main body outer bar and main body interior bar, 3 down position of limitation main body interior bar；It is taken using finishing
Go out mechanism, prevents main body interior bar 3 from deviating from from the lower end of main body outer bar 2.
The inner surface diameter direction of main body outer bar 2 is relatively set with two interior keys 22, corresponding, main body interior bar 3
Outer surface diameter direction is provided with the external card key 31 agreed with interior key 22.When user's turning tool, main body outer bar 2
Under the action of external force torque, it is in contact with the external card key 31 of main body interior bar 3 by interior key 22, to transmit torque, from
And realize the regulatory function of bolt.It needing to know, 31 effects of interior key 22 and external card key are to transmit torque, in order to
Meet the transmission demand of power, interior key 22 and 31 quantity of external card key change according to actual conditions.
Cross bar 1 is connected with the top of main body outer bar 2, for transmitting torque, the upper end of 2 ontology of main body outer bar, diametric(al)
On be provided through the placement hole 21 of main body outer bar 2, be straight-bar for disposing cross bar 1, cross bar 1.In use, cross bar 1 is injected
In placement hole 21, the rotation of cross bar 1 is grasped, according to lever principle, cross bar 1 can provide adjustment spiral shell by smaller power
Torque needed for bolt, and cross bar 1 can slide in placement hole 21, and torque size is adjusted convenient for user.Placement hole 21 is circle
Shape, cross bar 1 are circular pin, match with the shape of placement hole 21, are easily installed dismounting.It can know, according to wanting for torque
The shape of the custom of summation user, placement hole 21 and cross bar 1 is not fixed；Preferably, user is when in use, horizontal in order to prevent
Bar 1 is slipped out of the hand due to frictional force, and lateral, vertical or irregular anti-skid chequer can be arranged on cross bar 1；Corresponding placement hole 21 can be with
Hole wall can be threaded or sawtooth, for preventing cross bar 1 from deviating from.The outside of bar 2 is additionally provided with the machine of placement cross bar 1 outside the main body
Structure prevents the loss for causing cross bar 1 when not in use for placing cross bar 1.It could be aware that, cross bar and main body outer bar
Connection type is not unique, and in order to meet the needs of user, the shape of cross bar is not also unique.Optionally, it can also be set on cross bar
Clamping part is set, torque is transmitted for being clamped main body outer bar.
Preferably, bolt adjustment tool is also provided with the inside tune for being nested in 2 middle level of main body interior bar 3 and main body outer bar
Pole, for adjusting length in middle section tool for increasing, internal regulation bar is open column shape, similar to the shape of main body outer bar 2.
The outer surface diameter direction of portion's adjusting rod is provided with the external card key 31 agreed with interior key 22, the inner surface of internal regulation bar
It is provided with the larger bolt being in contact for some depth with the external card key 31 of main body interior bar 3, can be easily applicable in.
The quantity of internal regulation bar is more than or equal to 1, and quantity is not unique.According to specific circumstances, the depth of bolt hole also has
It is distinguished, the internal regulation bar of different number is set, can preferably adapt in the hole of different depth or be not easy the position touched
Use is set, and other structures need not be adjusted.
Lower part end 4 is fixedly installed on 3 bottom end of main body interior bar, is provided with connecting component above, can connect as needed
Screwdriver, sleeve or other mechanisms of different size, coordinate the work requirements under different occasions.
The operation principle of the present invention：Cross bar 1 can sliding in the placement hole 21 on 2 top of bar outside the main body, using lever original
Reason, the smaller power of use provide the torque needed for adjustment bolt；Main body outer bar 2 is sleeved on the outside with main body interior bar 3, main body outer bar 2
It can be moved along the direction of axis with main body interior bar 3, realize the elongation and contraction of the body of rod, the inside of main body outer bar 2 when rotation
Keyway 22 is in contact with the external card key 31 of main body interior bar 3, for transmitting torque；Lower part end 4 is fixed on the bottom of main body interior bar 3
Portion connects the mechanism of different size, is used directly to adjustment bolt as needed.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
