Abstract
The invention discloses a combined frame expansion connecting device, which includes an upper expansion sheet provided with an arc cavity at an tail end, and a lower expansion sheet provided with an arc tail end, wherein the arc tail end of the lower expansion sheet is inlaid in the arc cavity at the tail end of the upper expansion sheet, and moving intervals are reserved between upper and lower sides of the arc tail end of the lower expansion and the arc cavity at the tail end of the upper expansion sheet; a threaded hole is arranged on the upper expansion sheet, and a bolt capable of being contacted with the upper surface of the lower expansion sheet is arranged in the threaded hole; guide clamp grooves with the same shape are arranged in both the head part of the upper surface of the upper expansion sheet and the head part of the lower surface of the lower expansion sheet; stress grooves are arranged at mutually symmetrical parts at the middles of the upper expansion sheet lower surface and the lower expansion sheet upper surface; and an inner hexagonal countersink is arranged on the upper surface of the bolt. The combined frame expansion connecting device is provided with a simple structure, a structural section provided with a C-shaped groove in a side surface can be connected more firmly, a fixing device is not required to be additionally mounted, the mounting and dismounting as well as transportation are more convenient, and the product repeated utilization rate is also improved.
Description
Technical field
The present invention relates to a kind of expanded-connecting apparatus, relate in particular to a kind of combined type frame expanded-connecting apparatus.
Background technique
Support is widely used in various fields as a kind of support device for carrying object, as production line, lightly constructed and simply equipped building, device support etc.Existing support is to be combined in the mode of welding or riveted joint by section bar mostly, this assembling mode is cumbersome aspect transport in earlier stage and the dismounting in later stage, particularly welded structure, is just difficult to again combine utilization after dismounting, and early stage is also cumbersome while installing.
At present, also there is on the market a kind of easy-to-dismount combination frame, this combination frame is provided with through hole by centre, the section bar that C type groove is arranged in both sides forms, and when installation, by special can being connected with the contiguous block that C type groove coordinates, still this contiguous block still can produce certain gap after coordinating with C type groove, affect the stability of framework, therefore in order to prevent that framework from rocking, also need to be again fixed by bolt or other fastening piece, thereby cause installation procedure more complicated.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of side that can connect to be provided with C type channel section and the firm combined type frame expanded-connecting apparatus of linkage structure.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of combined type frame expanded-connecting apparatus, comprise that end is provided with upper swollen of circular arc chamber and end and is arranged to circular-arc lower swollen, described lower swollen circular-arc end is embedded in the circular arc chamber of described swollen end, and is provided with active interval between the described lower swollen upper and lower both sides of circular-arc end and the circular arc chamber of described swollen end; On described swollen, be provided with tapped hole, in tapped hole, be provided with can with the lower swollen bolt that upper surface contacts.
In order to coordinate with the section bar that is provided with C type groove, further, described swollen upper surface head is provided with lower swollen lower surface head the guiding draw-in groove that shape is identical.
In order to disperse the stress on expanded-connecting apparatus, more further, in the middle of described swollen lower surface and lower swollen upper surface, symmetrical position is provided with stress groove.
In order to make expanded-connecting apparatus distending, further, described bolt upper surface is provided with interior hexagonal counterbore.
Compared with prior art, usefulness of the present invention is: this combined type frame expanded-connecting apparatus is simple in structure, and the section bar that makes side be provided with C type groove connects more firm, without installing fixing device additional, installing/dismounting and transport more conveniently, has also improved Product repeat using rate.

embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of combined type frame expanded-connecting apparatus shown in Fig. 1, Fig. 2 and Fig. 3, comprise that end is provided with upper swollen 1 of circular arc chamber and end and is arranged to circular-arc lower swollen 2, described lower swollen 2 circular-arc ends are embedded in the circular arc chamber of described swollen 1 end, and are provided with active interval 6 between the described lower swollen 2 upper and lower both sides of circular-arc end and the circular arc chamber of described swollen 1 end; On described swollen 1, be provided with tapped hole, in tapped hole, be provided with the bolt 3 that can contact with lower swollen 2 upper surfaces; In order to make this expanded-connecting apparatus coordinate with the section bar that is provided with C type groove, described swollen 1 upper surface head is provided with lower swollen 2 lower surface heads the guiding draw-in groove 4 that shape is identical; In the middle of described swollen 1 lower surface and lower swollen 2 upper surfaces, symmetrical position is provided with stress groove 5, can make to act on the stress dispersion on this expanded-connecting apparatus; In order to make this expanded-connecting apparatus distending, described bolt 3 upper surfaces are provided with interior hexagonal counterbore.
As shown in Figure 4, its concrete assembling mode is as follows: the Surface of profile that is first provided with C type groove at side is offered circular hole, aperture is identical with the tapped hole aperture on upper swollen 1, then upper swollen 1 and lower swollen 2 of having inlayed put into section bar intermediate hole, make the tapped hole on swollen 1 aim at the circular hole on section bar, then the guiding draw-in groove 4 of upper swollen 1 and lower swollen 2 heads is coordinated with the C type groove on another part section bar, bolt 3 is coordinated with the tapped hole on upper swollen 1 through the circular hole on section bar, then screw by hex wrench, bolt 3 bottoms outwards eject lower swollen 2 simultaneously, draw-in groove 4 distending in C type groove makes to lead, block C type groove, be connected firmly.
This combined type frame expanded-connecting apparatus is simple in structure, and the section bar that makes side be provided with C type groove connects more firm, and without installing fixing device additional, installing/dismounting and transport more conveniently, has also improved Product repeat using rate.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
