Abstract

The utility model provides a connection structure for sectional materials, which includes at least two sectional materials and a connection piece for connecting the sectional materials. An opening groove is formed on each sectional material, two symmetrical convex ribs are protruded out from side walls of each opening groove and extend downwards to form clamping edges, and the convex ribs, the clamping edges and the side walls and the bottom surface of each opening groove form a positioning groove; and the connection piece is sleeved in the positioning groove, the shape of the section of the connection piece is matched with the shape of the positioning groove, the positions corresponding to the clamping edges on the two sides are sunk into a groove, and locking holes are arranged in preset positions on the connection piece. During the connection, the connection piece is sleeved into the two to-be-connected sectional materials along the positioning groove, screwing parts are screwed into the locking holes of the connection piece from the opening of the opening groove, and the connection piece is tightly pressed onto the bottom surface of the opening groove, therefore, the two sectional materials are connected into a whole, and the installation is convenient and rapid.

Description

A kind of linkage structure of section bar

Technical field

The utility model relates to a kind of linkage structure, is meant a kind of linkage structure of section bar especially.

Background technique

Present solar electrical energy generation engineering rack, product housings such as battery panel components are installed a kind of section bar of common use, by section bar product is carried out fastening location, and being connected with between section bar adopted welding, but have only employing destructive sawed-off in case need dismounting after the welding, and to use welding machine or saw in the operation, operation inconvenience, another kind is the movable connection method that adopts link, can repeat dismounting, as shown in Figure 1, on this section bar except being formed with chute, other be shaped elongated slot of a rectangle, link is arranged in the elongated slot of two section bars, the two ends of this link are provided with perforation, and each section bar offers lockhole on the position of corresponding link perforation, make screw pass lockhole and perforation in proper order, link is realized being connected of two section bars with section bar packing locking, but this Placement mainly contains following 2 deficiencies: the one, if section bar when splicing its lockhole of standard piece can offer in advance, as if not standard piece then lockhole must get the hole at the scene temporarily, operation is comparatively cumbersome; The 2nd, after screw passed lockhole and perforation locking, the one end still was exposed to the section bar outside, thereby influenced the aesthetic of section bar integral body.

The model utility content

Therefore, at above-mentioned deficiency, the utility model provides a kind of linkage structure of section bar, can make the connection between section bar more stable, and simple to operate, quick, and can keep section bar external form neat appearance.

For reaching above-mentioned purpose, the technical solution of the utility model is:

A kind of linkage structure of section bar, it comprises the link of at least two section bars and connection profile, forms an opening groove on each section bar, and the sidewall of this opening groove protrudes the fin of two symmetries, and fin extends to form the card edge downwards, by this fin, card along forming a locating slot with the sidewall and the bottom surface of opening groove; Described link is placed in this locating slot, and the shape in its cross section matches with the shape of this locating slot, and the position on corresponding card edge, its both sides is absorbed in a groove, and the pre-position is provided with lockhole on the link.

The utility model adopts said structure, during connection link is inserted in two section bars that need to connect along locating slot, utilize screw tightening to be screwed into the lockhole of link by the opening of opening groove, link is packed in the bottom surface of opening groove, two section bars can be connected as one like this, easy for installation, quick, it is good to connect rear stability simultaneously, and screw tightening does not expose and then can keep the neat appearance of section bar external form simultaneously.

Fig. 1 is a linkage structure of commonly using section bar;

Fig. 2 is the linkage structure stereogram of the utility model section bar;

Fig. 3 is the part exploded view of the linkage structure of the utility model section bar;

Fig. 4 is the linkage structure assembled sectional view of the utility model section bar.

Embodiment

Below in conjunction with drawings and the specific embodiments structure of the present utility model is explained.

Shown in Fig. 2,3,4, the linkage structure of a kind of section bar of the utility model, comprise two section bars 1 and connect the link 2 of two section bars 1, form the opening groove 11 that without exception is the U type on each section bar 1, bottom surface 14 with an opening 12, two side 13 and relative opening, the fin 15 of two symmetries is protruded near bottom surfaces 14 in the two side 13 of this opening groove, and fin 15 extends to form card downwards along 16, forms a locating slot along 16 with two side 13 and bottom surface 14 by this fin 15, card; Described link 2 can correspondence be placed in this locating slot, and the shape in its cross section matches with the shape of this locating slot, and the corresponding card in its both sides is absorbed in a groove 21 along 16 position, and the pre-position is provided with two lockholes 22 that connect on the link 2;

During connection, link 2 is inserted in two section bars 1 that need to connect along locating slot 17, utilizes screw tightening to be screwed into the lockhole of link 2, link is packed in the bottom surface 14 of opening groove, two section bars can be connected as one like this by the opening 12 of opening groove 11.After the connection,, further improve the stability after the section bar connection because the card of the groove 21 of link 2 and section bar can effectively prevent link and the play of section bar on level and longitudinal direction along 16 corresponding concavo-convex cooperations.

Adopt the obtainable beneficial effect of said structure to be: the utility model need not to offer at section bar the screw of the part 2 that is connected, make and connection is installed or dismantles more convenient, quick, it is good to connect simultaneously rear stability, and from the appearance, after the utility model locking, screw tightening is to be positioned at opening groove 11, and the section bar outside does not have exposed screw, can keep the neat appearance of section bar external form.

Claims

1. the linkage structure of a section bar, it is characterized in that: the link that comprises at least two section bars and connection profile, form an opening groove on each section bar, the sidewall of this opening groove protrudes the fin of two symmetries, and fin extends to form the card edge downwards, by this fin, card along forming a locating slot with the sidewall and the bottom surface of opening groove; Described link is placed in this locating slot, and the shape in its cross section matches with the shape of this locating slot, and the position on corresponding card edge, its both sides is absorbed in a groove, and the pre-position is provided with lockhole on the link.
