Abstract
The utility model discloses a shearing resistant lead core rubber support, which belongs to the technical field of lead core rubber supports. The shearing resistant lead core rubber support is mainlycharacterized by the inclusion of a bottom plate, a core body, a closing plate and a connecting plate, which are arranged from top to bottom, wherein the core body, the closing plate and the connecting plate are all provided with shear key holes, a bearing hole is arranged in the position where the bottom plate is opposite to the shear key hole, and a shear key is arranged inside both the shear key hole and the bearing hole. The shearing resistant lead core rubber support adopts the shear key to bear the horizontal force, and the shearing force born by the support is definite, so that the riskof the damage of multiple bolts arising from non-uniform force bearing due to the bolt-hole gap is eliminated. The shearing resistant lead core rubber support has the advantages of simple structure,low production cost, and high shearing resistance.
Description
Technical field
The utility model belongs to the lead core rubber support technical field, relates in particular to a kind of shearing resistance lead core rubber support.
Background technology
At present, lead core rubber support adopts a plurality of bolts that various piece is fixed, and mostly has the gap between bolt and the bolt hole, under the effect of horizontal force, each is bolt strained not of uniform size, like this, cause stressed big bolt crooked or fracture easily, and other bolts are not stressed.Under the effect of horizontal force, can cause remaining bolt failure again again.Thereby cause lead core rubber support to damage.
The utility model content
The technical problems to be solved in the utility model just provides a kind of simple in structure, cost of production is low, shearing resistance is strong shearing resistance lead core rubber support.
For addressing the above problem, the technical solution adopted in the utility model is: comprise base plate, core body, shrouding and the junction plate arranged from bottom to top, be provided with the shearing keyhole at described core body, shrouding and junction plate, the position relative with described shearing keyhole at described base plate is provided with receiving hole, is provided with shear connector in described shearing keyhole and receiving hole.
Its additional technical feature is:
Adopt between described shear connector and the described shrouding and be threaded;
Between described base plate, core body, shrouding and junction plate, be connected with set bolt;
The quantity of described shearing keyhole, receiving hole and shear connector is more than one.
Shearing resistance lead core rubber support provided by the utility model compared with prior art, have the following advantages: owing to comprise the base plate of arranging from bottom to top, core body, shrouding and junction plate, at described core body, shrouding and junction plate are provided with the shearing keyhole, the position relative with described shearing keyhole at described base plate is provided with receiving hole, in described shearing keyhole and receiving hole, be provided with shear connector, adopt shear connector to bear the horizontal force of lead core rubber support, the shearing that bearing bears is clear and definite, thereby has overcome the danger that a plurality of bolts are defeated in detail owing to the bolt hole gap causes discontinuity to cause; Its two be threaded owing to adopts between described shear connector and the described shrouding, by tightening shear connector, can apply prestressing force to the lead for retractable pencil of bearing, it is tightr that core body is contacted with peripheral rubber, the plumpness of raising lead core rubber support hysteresis loop; They are three years old, owing to be connected with set bolt between described base plate, core body, shrouding and junction plate, set bolt only plays the role of positioning in the lead core rubber support that does not bear pulling force, can determine the quantity and the diameter of set bolt by structure, and the corresponding thickness that reduces shrouding.To bearing the lead core rubber support of pulling force, set bolt can determine that the pulling force and the shearing of bearing are born by set bolt and shear connector respectively at this moment according to suffered pulling force size, and is stressed clear and definite, safe and reliable; Its four because the quantity of described shearing keyhole, receiving hole and shear connector is more than one,, a plurality of shear connectors can be set, to increase the tight ness rating that core body contacts with peripheral rubber to the bearing of a plurality of lead for retractable pencils.
Description of drawings
Accompanying drawing is the structural representation of the utility model shearing resistance lead core rubber support.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model shearing resistance lead core rubber support.
As shown in drawings, the utility model shearing resistance lead core rubber support comprises base plate 1, core body 2, shrouding 3 and the junction plate of arranging 4 from bottom to top, core body 2, shrouding 3 and junction plate 4 are provided with shearing keyhole 5, base plate 1 is provided with the receiving hole 6 corresponding with shearing keyhole 5, is provided with shear connector 7 in shearing keyhole 5 and receiving hole 6.Adopt shear connector 7 to bear the horizontal force of lead core rubber support, the shearing that bearing bears is clear and definite, thereby has overcome the danger that a plurality of bolts are defeated in detail owing to the bolt hole gap causes discontinuity to cause.
Adopt engage thread to be connected between shear connector 7 and the shrouding 3, promptly be provided with internal thread in the shearing keyhole 5 on shrouding 3, be provided with external screw thread in shear connector 7 and this internal thread corresponding position, by tightening shear connector 7, can apply prestressing force to the core body 2 of bearing, it is tightr that core body is contacted with the rubber of periphery, improves the plumpness of lead core rubber support hysteresis loop.
Be connected with set bolt 8 between base plate 1, core body 2, shrouding 3 and junction plate 4, set bolt 8 only plays the role of positioning in the lead core rubber support that does not bear pulling force, can determine the quantity and the diameter of set bolt by structure, and the corresponding thickness that reduces shrouding 3.To bearing the lead core rubber support of pulling force, set bolt 8 can determine that the pulling force and the shearing of bearing are born by set bolt 8 and shear connector 7 respectively at this moment according to suffered pulling force size, and is stressed clear and definite, safe and reliable.
In order to increase the tight ness rating that core body 2 contacts with peripheral rubber, the quantity of shearing keyhole 5, receiving hole 6 and shear connector 7 is more than one, to the bearing of a plurality of core bodys 2, a plurality of shear connectors 7 can be set.
The foregoing description is just to explanation of the present utility model, and therefore, protection domain of the present utility model not only is confined to the foregoing description, as long as structure is identical with the utility model shearing resistance lead core rubber support, just drops on the scope of the utility model protection.
