Description
Technical field
The utility model belongs to machine tool technical field, is specifically related to a kind of scalable operation spanner.
Background technology
When carrying out the operations such as back brake in electric substation, the bolt head usually needing staff to utilize the wheel case of spanner to be enclosed within square or regular polygon carries out the dismounting of bolt, but because electric substation inner space is narrow and small, and the height of different operating personnel and brachium all different, therefore the spanner of unified specification is difficult to the action need adapting to different people, when making to operate, not only efficiency is lower, and it is also larger to the physical demands of staff, and wheel case and the handle of existing spanner are in same plane, when rotary handle because the machinery equipment of electric substation and handle are fitted close together, therefore the easy hand to staff causes scuffing, the injury such as to damage.
Utility model content
The purpose of this utility model is to provide a kind of scalable operation spanner, and the spanner solving existing unified specification is difficult to the shortcoming adapting to different people action need.
The technical scheme that the utility model adopts is: scalable operation spanner, comprise the locking bar wheel case, handle bar and the connecting rod that are connected successively, connecting rod is provided with multiple locating hole, connecting rod is sheathed with extension rod cover, extension rod puts and is provided with trepanning, and connecting rod is fixed by the fixation kit passing the corresponding locating hole in position and trepanning with extension rod cover.
Feature of the present utility model is also,
Fixation kit is made up of the bolt be equipped with, nut.
The angle of handle bar and locking bar wheel case place plane is 8 °-12 °, and handle bar and connecting rod are on same straight line.
The beneficial effects of the utility model are: the spanner that scalable operation spanner of the present utility model solves existing unified specification is difficult to the shortcoming adapting to different people action need.Scalable operation spanner structure of the present utility model is simple, it is made to be applicable to different staff operation in the region of narrow space through regulating handle length, improve operating efficiency, and between handle and wheel case plane, 8 ° of-12 ° of angles designs avoid the scuffing of staff, the generation of the industrial accident such as to damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of scalable operation spanner of the present utility model;
Fig. 2 is the side view of scalable operation spanner of the present utility model.
In figure, 1. locking bar wheel case, 2. handle bar, 3. connecting rod, 4. locating hole, 5. fixation kit, 6. trepanning, 7. extension rod cover.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
The scalable operation spanner structure that the utility model provides as depicted in figs. 1 and 2, comprise the locking bar wheel case 1, handle bar 2 and the connecting rod 3 that are connected successively, connecting rod 3 is provided with multiple locating hole 4, connecting rod 3 is sheathed with extension rod cover 7, extension rod cover 7 is provided with trepanning 6, connecting rod 3 is fixed with the fixation kit 5 of trepanning 6 by the locating hole 4 corresponding through position with extension rod cover 7, and fixation kit 5 is made up of the bolt be equipped with, nut.
Handle bar 2 is 8 °-12 ° with the angle of locking bar wheel case 1 place plane, and handle bar and connecting rod 3 are on same straight line.
During use, first according to the height of different working spaces and operating personnel, the concrete conditions such as brachium, extension rod cover 7 is linked in the correct position on connecting rod 3, bolt is utilized when locating hole 4 is corresponding with trepanning 6 position, connecting rod 3 and extension rod cover 7 are fixed by the fixation kit 5 of nut composition, then locking bar wheel case 1 is linked on bolt head that is to be removed or that install, because locking bar wheel case 1 and handle bar 2 are not in same plane, the end that handle bar 2 grips for staff is higher than locking bar wheel case 1 place plane, therefore the place making staff's hand grip and locking bar wheel case 1 and machinery equipment place plane are kept certain height distance, the scuffing to operating personnel's hand is avoided when screwing bolt, the generation of industrial accident such as to damage.Particularly, when handle bar 2 and the angle of locking bar wheel case 1 place plane are too small, the hand of staff still can touch machinery equipment surface, and when angle is excessive, then not only comparatively large to the physical demands of staff, and easily cause fractureing of handle bar 2, through experimental verification, when handle bar 2 is 8 °-12 ° with the angle of locking bar wheel case 1 place plane, the hand of staff would not touch machinery equipment, and operating efficiency is the highest.
