It is circular -arc with all setting to on the conflict face that first activity connects and the second activity connects, can do all can by effectual dispersion interact between the two in convenient rotatory, avoided the serious circumstances of local atress, can not result in deformation.
Description
Technical field
This utility model relates to connecting device, particularly to a kind of adaptor for handrail.
Background technology
The stair of buildings in general, aisle are both provided with greatly hand banisters, with secondary row people walk, and normally used be metal tube handrail, when this handrail is arranged, its metal handrail typically requires to turn along stair or aisle and splices, and is now accomplished by the constructional device of turning joint.
At present, the Chinese patent that notification number is CN203441023U discloses a kind of turning joint for staircase handrail device, it includes the first active joint and the second active joint, first active joint and the second active joint are all pivotally connect by middle, can there is relative rotation in both, but it is bonded to each other with right angle under extreme angles inside between both, the contact surface local pressure that the hard contact of this plane goes down to easily cause active joint for a long time is serious, causes expendable deformation.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that the adaptor for handrail providing a kind of two active joint binding face holding capacity stable.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of adaptor for handrail, including rotating shaft, by the first active joint that rotating shaft plugs together, second active joint, first active joint is integrally formed with clamping block, described second active joint is provided with a pair fixed block, the cavity plugged together for clamping block is formed between described fixed block, the outside of two described fixed blocks is arc surface, and it is consistent with fixed block shape with the face of fixed block laminating on described first active joint, described fixed block and described clamping block are provided with mean for the through hole that rotating shaft runs through.
Pass through technique scheme, after its outward flange of fixed block being used for connecting clamping block is arranged to arc surface, it is also combined closely by arc surface and the first active joint, the way of contact of this circular arc, making both when extruding mutually, the strength of end face aspect can spread out uniformly, it is ensured that avoids the serious situation of local pressure and occurs, stress can be spread out uniformly, nor the situation of deformation easily occurs.
Preferably, described clamping block is cylindrical.
Preferably, described fixed block is hemispherical, and diameter is consistent with the diameter of described clamping block.
Pass through technique scheme, the structure that cylindrical clamping block combines with semicircle fixed block can allow the first active joint and the second active joint keep certain integraty in attachment structure, clamping block and the round structure of fixed block can be easy to both mutual motions, and this structure is when rotating shaft traverse, above its rotating shaft, bearing capacity also is able to dispersed, it is ensured that stablizing in overall structure.
Preferably, described first active joint and described second active joint are hollow structure.
By technique scheme, the structure of hollow structurally reduces the structural material consumption of entirety as far as possible, is so installing, the armrest straight on both sides patch be combined on the first active joint and the second active joint just can, very simple and convenient.
In sum, what this utility model in contrast to prior art has the beneficial effect that in the resistance surface by the first active joint and the second active joint to be all provided with being set to arc-shaped, interaction force between the two can be effectively disperseed while convenient rotation, avoid the situation that local pressure is serious, it is not result in deformation, and the first active joint and the second active joint card each other under this structure is right higher, globality is stronger, in the process rotated, clamping is stable each other, the ability met with stresses will not be caused different because folding angle is different.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in the figures 1 and 2, a kind of adaptor for handrail, including rotating shaft 3, first active joint the 1, second active joint 2 of being plugged together by rotating shaft 3, first active joint 1 and the second active joint 2 are all made of aluminum, the structure of the first active joint 1 and the second active joint 2 inner homogeneous hollow, the shape of two active joints is basically identical, difference be, first active joint 1 is integrally formed with clamping block 11, second active joint 2 is provided with a pair fixed block 21 plugged together for clamping block 11, forms the cavity plugged together for clamping block 11 between fixed block 21.Rotating shaft 3 is through and two fixed blocks 21 and clamping block 11, it it is all the structure of hollow owing to fixed block 21 and clamping block 11 are internal, in order to facilitate plugging together of rotating shaft 3, it is designed with and the passage of rotating shaft 3 laminating in fixed block 21 and clamping block 11, it is ensured that rotating shaft 3 can conveniently be stablized when inserting.
First active joint 1 and the second active joint 2 two are all plug together the corner at handrail, it is ensured that the bending place stable connection of handrail.
As shown in Figure 3, second active joint 2 is arranged above with two fixed blocks 21, the outer shape of two fixed blocks 21 is arc surface 4, in figure 4 indicate indicated, the shape of so whole fixed block 21 is just hemispherical, and two fixed blocks 21 are symmetrical, one cavity of fixed block 21 intermediate formation, clamping block 11 is just fastened between fixed block 21, it is ensured that clamping block 11 can be clamped by fixed block 21 so that clamping block 11 can engage by stable carrying out.Wherein, the bottom surface of the second active joint 2 is arc surface 4, it is possible to facilitate the rotation of clamping block 11.
As shown in Figure 4, first active joint 1 is arranged above with the clamping block 11 of a cylindrical shape, the diameter of clamping block 11 is consistent with the diameter of fixed block 21, such first active joint 1 and the second active joint 2 keep certain integraty in attachment structure, clamping block 11 and the round structure of fixed block 21 can be easy to both mutual motions, and this structure is when rotating shaft 3 traverse, its rotating shaft 3 bearing capacity above also is able to dispersed, it is ensured that stablizing in overall structure.On first active joint 1 consistent with face and fixed block 21 shape of fixed block 21 laminating, figure indicates indicated by 4, after its outward flange of fixed block 21 being used for connecting clamping block 11 is arranged to arc surface 4, it is also combined closely by arc surface 4 and the first active joint 1, the way of contact of this circular arc, make both when extruding mutually, the strength of end face aspect can spread out uniformly, guarantee that avoiding the serious situation of local pressure occurs, stress can be spread out uniformly, nor the situation of deformation easily occurs.
The above is only exemplary embodiment of the present utility model, and not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
