A kind of triangle device and circular knitting machine being switched fast track
Technical field
The utility model relates to a kind of triangle devices.
Background technique
Well known, triangle device is made of triangular mounting seat and corner block, and corner block is fixed on triangular mounting seat, triangle
Triangle track is formed on block, which is that fixed structure then needs replacing entire three when needing replacing triangle track
There is the problems such as dismounting is inconvenient in hornblock.
Summary of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of triangle device that can be switched fast track
And circular knitting machine.
The purpose of this utility model is realized by following technical solution:
A kind of triangle device being switched fast track, including triangular mounting seat, it is characterised in that: further include fixing three
Angle, bolt cam and retaining mechanism, triangular mounting seat are formed with up and down for placing the mounting hole of bolt cam, activity three
Angle includes main body and two triangular parts, and main body is adapted with mounting hole size, and two triangular portions are located at the both ends of main body, fixed triangle
It is fixed at triangular mounting seat bottom surface, fixed triangle is formed with the relief hole for protruding into for triangular part up and down, locking
For fixing bolt cam, the triangular part and fixed triangle cooperation for protruding into relief hole constitute triangle track, two triangular parts tool for mechanism
There is different structures to constitute different triangle tracks.
Further, the relief hole makes the main body can not be by moving down to limit the bolt cam.
Further, the retaining mechanism is the pressing plate that the triangular mounting seat top surface is detachably arranged at by bolt,
The pressing plate pushes down the top surface of the bolt cam with the fixation bolt cam.
A kind of circular knitting machine, it is characterised in that: including the triangle device.
The utility model has the following beneficial effects:
When needing replacing triangle track, the retaining mechanism that need to only dismantle takes out bolt cam from mounting hole, and turns round
Direction is reloaded into mounting hole, is locked again, easy to operate.
Relief hole limitation main body passes through, and retaining mechanism uses pressing plate and bolt, and simple, convenient for disassembly and assembly with structure is excellent
Point.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Shown in referring to Fig.1, a kind of triangle device being switched fast track, including triangular mounting seat 1, fixed triangle 2, work
Dynamic triangle 3 and retaining mechanism, triangular mounting seat 1 are formed with up and down for placing the mounting hole 11 of bolt cam 3, activity three
Angle 3 includes main body 31 and two triangular parts 32,33, and main body 31 is adapted with 11 size of mounting hole, and two triangular parts 32,33 set up separately in master
The both ends of body 31, fixed triangle 2 are fixed at 1 bottom surface of triangular mounting seat, and fixed triangle 2 is formed with up and down for for three
The relief hole 21 that corner 32,33 is protruded into, the triangular part 32,33 and the cooperation of fixed triangle 2 for protruding into relief hole 21 constitute triangle track,
Two triangular parts 32,33 have different structures to constitute different triangle tracks.
Relief hole 21 makes main body 31 can not be by moving down to limit bolt cam 3, and retaining mechanism is to pass through bolt 41
It is detachably arranged at the pressing plate 4 of 1 top surface of triangular mounting seat, which pushes down the top surface of bolt cam 3 to fix bolt cam
3。
When needing replacing triangle track, the retaining mechanism that need to only dismantle takes out bolt cam 3 from mounting hole 11, and falls
Turn direction to be reloaded into mounting hole 11, lock again, it is easy to operate.
The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this
Range should still belong to this that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of utility model patent is covered.
