Abstract
The open a kind of back-up ring extracting tool of this utility model.The technical scheme used includes handle, it is characterized in that: described handle front end connects disassembly mechanism, described disassembly mechanism includes " L " shape removal rod and is arranged on the Tool for detaching of " L " shape removal rod front end, described Tool for detaching offers square dismounting mouth, and this square dismounting mouth adapts with the crescent dismounting end of back-up ring.Back-up ring extracting tool advantage of the present utility model is as follows: during dismounting, if the square dismounting mouth of instrument is penetrated back-up ring crescent dismounting end in, then pull-out back-up ring, dismantle very convenient quickly.
Description
Technical field
This utility model relates to a kind of extracting tool, specifically a kind of back-up ring extracting tool.
Background technology
Common cassette back-up ring because there is ear in its structure, cause with interior feature contacts and interfere, as being not provided with ear
Its dismounting of portion bothers the most very much.And for the highest aerospace field of exact requirements, common cassette back-up ring cannot meet it
Requirement.
For the problems referred to above, applicant proposed a kind of Aero-Space back-up ring, its structure includes by flat tinsel
The annular retaining ring body of coiling, the two ends of annular retaining ring body are provided with substantially in meniscate breach.The gear of this structure
Circle, it cannot be dismantled by the extracting tool of common cassette back-up ring, it is therefore desirable to a kind of special back-up ring extracting tool, to improve it
The convenience of dismounting.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of back-up ring dismounting work being applicable to Aero-Space back-up ring
Tool.
For solving the problems referred to above, the technical solution adopted in the utility model includes handle, it is characterised in that: before described handle
End connection has disassembly mechanism, described disassembly mechanism include " L " shape removal rod and are arranged on the dismounting of " L " shape removal rod front end
Head, described Tool for detaching offers square dismounting mouth, and this square dismounting mouth adapts with the crescent dismounting end of back-up ring.
Described back-up ring extracting tool, it is characterised in that: the retaining mechanism that described handle is arranged by front end is torn open with described
" L " shape removal rod locking of release mechanism connects.
Described back-up ring extracting tool, it is characterised in that: described retaining mechanism includes at least two clamping of handle front end
Portion, described clamping part is provided with locking nut, and described locking nut jam-packed can make clamping part draw in, and clamp described disassembly mechanism
" L " shape removal rod.
Back-up ring extracting tool advantage of the present utility model is as follows: during dismounting, as long as the square dismounting mouth of instrument is penetrated gear
Circle crescent dismounting end in, then pull-out back-up ring, dismantle very convenient quickly.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model back-up ring extracting tool；
Fig. 2 is the use state reference map of this utility model back-up ring extracting tool.
Detailed description of the invention
As shown in Figure 1 to Figure 2, back-up ring extracting tool of the present utility model, including the handle of cylindricality, described handle 1 front end
Connecting has disassembly mechanism, described disassembly mechanism include " L " shape removal rod 2 and are arranged on the dismounting of " L " shape removal rod 2 front end
3, described Tool for detaching 3 offers square dismounting mouth 4, and the crescent of this square dismounting mouth 4 and back-up ring 5 is dismantled end 6 and adapted.
For optimizing such scheme further, the retaining mechanism that described handle 1 is arranged by front end and described disassembly mechanism
The locking of " L " shape removal rod 2 connects.Described retaining mechanism includes two clamping parts 7 of handle 1 front end, and described clamping part 7 is provided with
Locking nut 8, described locking nut 8 jam-packed can make clamping part 7 draw in, and clamps " L " shape removal rod 2 of described disassembly mechanism.
By arranging retaining mechanism, described disassembly mechanism can arbitrarily be changed, and can change relative according to the back-up ring of different size
Disassembly mechanism.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any amendment, equivalent and the improvement etc. made within novel spirit and principle, are all contained in protection of the present utility model
Within the scope of.
