Abstract
The utility model belongs to the technical field of diesel locomotive accessory technique and specifically relates to a three brails with adjustable rigidity. This rigidity includes regulating plate no. 1 and regulating plate no. 2, both ends are equipped with the locating hole about the regulating plate, two locating hole amalgamations on regulating plate top, the regulating plate bottom is equipped with the location strip, the location strip below of regulating plate no. 1 is equipped with the dogtooth, the location strip top of regulating plate no. 2 is equipped with concave tooth, dogtooth and concave tooth intermeshing, location strip middle part is equipped with the location dead slot, the location strip is through the three adjustable brails of fastening bolt fixed connection at location dead slot both ends, be equipped with the elasticity node in the locating hole, the elasticity node passes through the jump ring on top to be fixed in the locating hole. Three brails with adjustable rigidity simple structure after the improvement is reliable, and the manufacturability is good, has effectively improved the application scope of pull rod, and same pull rod is applicable to the occasion of different rigidity demands, has greatly improved the utilization ratio of pull rod, saves the cost.
Description
Technical field
The utility model relates to internal combustion locomotive accessory technical field, especially a kind of stiffness-adjustable triangular draw bar.
Background technique
Existing triangular draw bar is fixed structure, once sizing cannot match different pull bar integral rigidities by varying sized, therefore different rigidity requirement occasions needs the pull bar of different structure, and often kind of pull bar needs to develop different moulds, and cost is higher.
Model utility content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of stiffness-adjustable triangular draw bar.
The utility model solves the technological scheme that its technical problem adopts: a kind of stiffness-adjustable triangular draw bar, comprise regulator plate one and regulator plate two, the upper and lower two ends of regulator plate are provided with positioning hole, two positioning hole splits on regulator plate top, positioning strip is provided with bottom regulator plate, double wedge is provided with below the positioning strip of regulator plate one, recessed tooth is provided with above the positioning strip of regulator plate two, double wedge and recessed tooth engage each other, be provided with location dead slot in the middle part of positioning strip, positioning strip is fixedly connected with by the clamping bolt of locating dead slot two ends.
According to another embodiment of the present utility model, comprise in positioning hole further and be provided with elastic panel nodes, elastic panel nodes is fixed in positioning hole by the jump ring on top.
The beneficial effects of the utility model are, simple and reliable for structure, and manufacturability is good, and effectively improve the Applicable scope of pull bar, same pull bar is applicable to the occasion of different-stiffness demand, greatly improves the utilization ratio of pull bar, save cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is decomposition view of the present utility model.
1. jump rings, 2. elastic panel nodes in figure, 3. regulator plate one, 4. regulator plate two, 5. clamping bolt, 6. positioning hole, 7. double wedge, 8. recessed tooth, 9. locate dead slot, 10. positioning strip.
Embodiment
As Fig. 1, shown in 2, a kind of stiffness-adjustable triangular draw bar, comprise regulator plate 1 and regulator plate 24, the upper and lower two ends of regulator plate are provided with positioning hole 6, two positioning holes 6 split on regulator plate top, positioning strip 10 is provided with bottom regulator plate, double wedge 7 is provided with below the positioning strip 10 of regulator plate 1, recessed tooth 8 is provided with above the positioning strip 10 of regulator plate 24, double wedge 7 and recessed tooth 8 engage each other, location dead slot 9 is provided with in the middle part of positioning strip 10, positioning strip 10 is fixedly connected with by the clamping bolt 5 at dead slot 9 two ends, location, elastic panel nodes 2 is provided with in positioning hole 6, elastic panel nodes 2 is fixed in positioning hole 6 by the jump ring 1 on top.
During use, three elastic panel nodes 2 of this pull bar rely on regulator plate 1 and regulator plate 24 to be connected into one, the double wedge 7 that regulator plate 1 and regulator plate 24 are arranged and recessed tooth 8 engage each other, the relative position of three elastic panel nodes 2 is regulated by changing total number of teeth in engagement, and then the pull bar integral rigidity required for obtaining, adjustment process simple and fast, possesses the reliable feature of flexible structure, and substantially increase the Applicable scope of pull bar, utilize clamping bolt 5 secured adjusted plate, simple and reliable for structure, be easy to processing and assembling, elastic panel nodes 2 is located by jump ring 1, facilitate the external interface on adjustable elastic node 2, all the time ensure that it coordinates closely with the junction plane of external component, ensure adhesive strength.
Stiffness-adjustable triangular draw bar after improvement is simple and reliable for structure, and manufacturability is good, and effectively improve the Applicable scope of pull bar, same pull bar is applicable to the occasion of different-stiffness demand, greatly improves the utilization ratio of pull bar, saves cost.
