Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, implement below in conjunction with the utility model
Attached drawing in example, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality
Applying example is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this reality
With novel protected range.
The telescopic bolt of one kind 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 transmitting 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, contacts at the top of 2 bottom of main body outer bar and main body interior bar 3 at this time, limits 3 down position of main body interior bar；It is taken using finishing
Mechanism out 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 by interior key 22 with the external card key 31 of main body interior bar 3, 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 transmitting torques, in order to
Meet the transmitting demand of power, interior key 22 and 31 quantity of external card key change according to the actual situation.
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, diametrical direction
On be provided with placement hole 21 through main body outer bar 2, for disposing cross bar 1, cross bar 1 is straight-bar.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 lesser power
Torque needed for bolt, and cross bar 1 can slide in placement hole 21, adjust torque size 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 disassembly.It can know, according to wanting for torque
The shape of the habit 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, settable lateral, vertical or irregular anti-skid chequer on cross bar 1；Corresponding placement hole 21 can be with
The settable screw thread of hole wall 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, transmits torque for being clamped main body outer bar.
Preferably, bolt adjustment tool is also provided with the inside tune for being nested in 2 middle layer 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 biggish bolt being in contact with the external card key 31 of main body interior bar 3 for some depth, 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 does not need adjustment other structures.
Lower part end 4 is fixedly installed on 3 bottom end of main body interior bar, is provided with connecting component above, can according to need connection
Screwdriver, sleeve or other mechanisms of different size, cooperate the work requirements under different occasions.
The working principle of the utility model：Cross bar 1 can sliding in the placement hole 21 on 2 top of bar outside the main body, using thick stick
Rod principle, torque needed for providing adjustment bolt with lesser power；2 sets of main body outer bar outside the outside with main body interior bar 3, main body
Bar 2 can be moved with main body interior bar 3 along the direction of axis, realize the elongation and contraction of the body of rod, and main body outer bar 2 is interior when rotation
Portion's 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 main body interior bar 3
Bottom connects the mechanism of different size as needed, is used directly to adjustment bolt.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
