Description
Technical field
This utility model relates to pivoted arm assembly, has particularly related to exhaust brake valve pivoted arm fixed structure.
Background technology
In the market for the exhaust brake valve of electromotor auxiliary braking, pivoted arm assembly structure is frequently with welding or locking
Nut check is locking or spring washer is locking, and in product is actually used, these several structures often cause pivoted arm to come off or nut
Loosen phenomenon, thus cause exhaust brake defective valve.For Welding Structure, cause pivoted arm to come off, be owing to rotating shaft material is often adopted
With high strength alloy steel, higher to welding process requirement, need weld preheating to process, supplier's actual production inconvenient operation with
And cost reason, Chang Hui saves this operation, causes rotating shaft scaling loss, and pivoted arm comes off；Nut is connected, uses spring washer locking, due to
Operating mode is severe, and shock and vibration are bigger, it is easy to cause nut loosening, and then it is big to affect valve clearance change, causes exhaust brake
Defective valve.
Summary of the invention
The shortcoming that this utility model easily departs from rotating shaft for pivoted arm in prior art, it is provided that exhaust brake valve pivoted arm is fixed
Structure.
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals: exhaust brake valve turns
Arm fixed structure, including rotating shaft and the pivoted arm that is fixed in rotating shaft, one end of rotating shaft is provided with mounting post, and the diameter of mounting post is less than
The diameter of rotating shaft, mounting post is provided with screw thread, and pivoted arm is arranged in mounting post and is fixed by the nut with threaded engagement, installs
Post is provided with the hole vertical with the axis direction of mounting post, is provided with straight-bar in hole, and it is external part that straight-bar stretches out the one end outside hole,
The external part of straight-bar is provided with the gag lever post parallel with mounting post, and pivoted arm is provided with the spacing hole coordinated with gag lever post, gag lever post
By pivoted arm being positioned with coordinating of spacing hole.By straight-bar and the design of gag lever post, make pivoted arm solid not only by nut
Fixed, carry out secondary also by the cooperation of gag lever post and spacing hole spacing, be prevented effectively from nut and get loose during vibrations and make
The infringement become, it is ensured that the reliability that pivoted arm and rotating shaft connect.
As preferably, gag lever post includes the fixing bar being fixed on straight-bar and the expansion link being connected with fixing bar, fixing bar
And spring is installed between expansion link and realizes the flexible of gag lever post by spring.Pacified by the design convenient construction personnel of spring
Assembly and disassembly.
As preferably, the upper end open of expansion link, the opening of expansion link is set in the lower end of fixing bar, one end of spring
Being connected with the lower surface of fixing bar, the other end of spring is connected with the inner surface of expansion link.
As preferably, pad is installed between nut and pivoted arm.By the setting of pad make that nut installs more firm,
Ensure stablizing of structure.
This utility model, owing to have employed above technical scheme, has significant technique effect: by straight-bar and gag lever post
Design, make pivoted arm fix not only by nut, carry out secondary also by the cooperation of gag lever post and spacing hole spacing, be prevented effectively from
The infringement that nut gets loose during vibrations and causes, it is ensured that the reliability that pivoted arm and rotating shaft connect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the gag lever post of Fig. 1.
The toponym that in accompanying drawing, each number designation is referred to is as follows: 1 rotating shaft, 2 pivoted arms, 3 mounting posts, 4 straight
Bar, 5 gag lever posts, 6 springs, 7 nuts, 8 pads, 21 spacing holes, 31 holes, 32 screw threads, 51 fix bar,
52 expansion links.
Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
Exhaust brake valve pivoted arm fixed structure, as it can be seen, include rotating shaft 1 and the pivoted arm 2 being fixed in rotating shaft 1, rotating shaft 1
One end be provided with mounting post 3, the diameter of mounting post 3 is less than the diameter of rotating shaft 1, and mounting post 3 is provided with screw thread 32, and pivoted arm 2 is installed
Fixing in mounting post 3 and by the nut 7 coordinated with screw thread 32, mounting post 3 is provided with vertical with the axis direction of mounting post 3
Hole 31, straight-bar 4 is installed in hole 31, it is external part that straight-bar 4 stretches out the one end outside hole 31, the external part of straight-bar 4 be provided with
The gag lever post 5 that mounting post 3 is parallel, pivoted arm 2 is provided with the spacing hole 21 coordinated with gag lever post 5, and gag lever post 5 inserts in spacing hole 21
And pivoted arm 2 is positioned.
Gag lever post 5 includes the fixing bar 51 being fixed on straight-bar 4 and the expansion link 52 being connected with fixing bar 51, fixing bar 51
