The specific embodiment
Be further described below in conjunction with the technical solution of the utility model of embodiment.
Embodiment 1
Referring to Fig. 1, Fig. 2, a kind of fastening devices comprises first claw 1, second claw 2 and the connecting portion 3 that is used for being connected first claw and second claw, also comprises the free-ended fixed part be used to the free end of fixing first claw 1 and second claw 2.During use, supporting frame 11 (being generally steel pipe) is blocked in the hole that first claw 1 and second claw 2 pass on the frame plate 12, connecting portion 3 is blocked by the edge in hole on the frame plate, thereby play the effect that frame plate 12 and supporting frame 11 are fixed together, owing to be provided with fixed part, can prevent that first claw 1 and second claw 2 from deviating from from supporting frame 11, further improve safety, and installation and convenient disassembly.
The free end of described first claw 1 is that first claw 1 is away from an end of connecting portion 3; The free end of described second claw 2 is that second claw 2 is away from an end of connecting portion 3.
In the present embodiment, optional, described fixed part is snap part.So arrange, can be the free end of the free end of first claw 1 and second claw 2 is safer, firmly fixing, prevent that better first claw 1 and second claw 2 from deviating from from supporting frame 11, further improved safety, and install and dismounting also convenient.
In the present embodiment, optional, described snap part comprises dop 4 and the snap ring 5 that is clasped mutually, and described dop 4 is arranged on the free end of first claw 1, and described snap ring 5 is connected with the free end of second claw 2.So arrange, after being stuck in first claw 1 and second claw 2 on the supporting frame 11, snap ring 5 engaged with dop 4 can preventing that first claw 1 and second claw 2 are from supporting frame 11 disengagings.
In the present embodiment, optional, described first claw 1, second claw 2 and connecting portion 3 are wholely set.Namely first claw 1, second claw 2 and connecting portion 3 can be formed by the moulding process bending by the thick steel of 1-3mm.So arrange, have and make simply the advantage that cost of production is low.
In the present embodiment, optional, the outwardly-bent formation dop 4 of the free end of described first claw 1.During use, directly snap ring 5 is stuck on the dop 4 and gets final product.So arrange, make dop 4, first claw 1, second claw 2 and connecting portion 3 all be structure as a whole, not only convenient formation, and safety factor is also higher.
In the present embodiment, optional, the cross section of described first claw 1, second claw 2 is circular arc, and the arc radius of first claw 1, second claw 2 is identical.So arrange, make and form the circular ccontaining cavity of supporting frame between the claw 1 of winning, second claw 2, first claw 1, second claw 2 can be better and supporting frame 11 applyings, and what supporting frame 11 can be engaged is tighter.
In the present embodiment, optional, the width of described connecting portion 3 is greater than the width of first claw 1, and the width of connecting portion 3 is greater than the width of second claw 2.This described width is the horizontal span among Fig. 2.Because the width of connecting portion 3 is bigger, therefore, first claw 1, second claw 2 and fixed part can pass the hole on the frame plate 12, and connecting portion 3 width are bigger, are stuck in above the frame plate 12.
In the present embodiment, optional, described snap ring 5 is rotationally connected by the free end of draw ring 6 and second claw 2.So arrange, just can realize the folding of snap ring 5 and dop 4 by pulling draw ring 6, pull draw ring 6 when downwards, just snap ring 5 can be stuck on the dop 4, upwards pull draw ring 6 then with snap ring 5 chuckings, when dismounting, pull draw ring 6 downwards, just snap ring 5 can be broken away from from dop 4.
In the present embodiment, optional, described draw ring 6 is provided with the draw ring retainer plate, and draw ring retainer plate one end is connected with rotating shaft, and the other end is connected with handle 10; One end of described snap ring 5 is fixed in the described draw ring retainer plate; The free end of described second claw 2 is provided with shaft hole, and described rotating shaft is arranged in the described shaft hole.Described draw ring retainer plate, rotating shaft, handle can be formed by a steel bar bending.So arrange, by pulling handle 10 rotating shaft is rotated, thus drive snap ring 5 away from or near the free end of first claw 1.
In the present embodiment, optionally, described shaft hole comprises first shaft hole 801 and second shaft hole 802, and be separately positioned on the both sides of the free end outside of second claw 2, described rotating shaft comprises first rotating shaft 901 and second rotating shaft 902, and described draw ring retainer plate comprises the first draw ring retainer plate 701 and the second draw ring retainer plate 702; One end of described first rotating shaft 901 is arranged in first shaft hole 801, and the other end is connected with the first draw ring retainer plate 701; One end of described second rotating shaft 902 is arranged in second shaft hole 802, and the other end is connected with the second draw ring retainer plate 702; Described handle 6 is connected with the first draw ring retainer plate 701 and the second draw ring retainer plate 702 respectively.So arrange, can make fastening power moderate, and fastening is more solid firm.
