Abstract

The utility model discloses a fixing device for crossed connection of rod pieces. A positioning rack is fixed on one rod piece, and an installing rack is fixed on the other rod piece. Positioning surfaces, installing surfaces, and positioning inclined surfaces are respectively arranged on the positioning rack and on the installing rack, and the positioning surfaces and the positioning inclined surfaces are opposite. Matched lug bosses with an inclined edge are respectively arranged on the two positioning surfaces. When the positioning rack and the installing rack are connected through screw bolts and screw nuts, the positioning inclined surfaces are matched, and the inclined edges on the two lug bosses are matched, and therefore, the two rod pieces are mutually positioned in the three directions of space for guaranteeing installation precision.

Description

The cross-coupled fixing device of a kind of rod member

The utility model relates to a kind of cross-coupled fixing device of rod member that is used to set up canopy, frame etc.

At present people have the mode of tying up that adopts when setting up canopy, frame etc., have to adopt joint style, have to adopt welding manner, or the like.The always each have their own deficiency of above-mentioned variety of way.Bundling type is firm inadequately; Joint style needs links such as more bolt, nut; Welding manner causes rod member to get rusty easily and can not dismantle.And the common shortcoming of these modes is difficult to accurate location exactly, that is to say be difficult to guarantee to install after, accurate relative position is arranged between the rod member, can not satisfy requirement when setting up the highi degree of accuracy framework.

The purpose of this utility model is a kind of simple in structure, firm in order to provide, and is convenient to dismounting and the cross-coupled fixing device of the pinpoint rod member of energy.

Structural feature of the present utility model is: be fixed with position shelf on the rod member, be fixed with scaffold on another rod member, locating face is arranged on the position shelf, attachment face, the inclined-plane, location, locating face is relative with the inclined-plane, location, confined planes is vertical with aforementioned three faces, the boss that one band hypotenuse is arranged on the locating face, on attachment face and the inclined-plane, location a mounting hole is arranged respectively, have on the scaffold and the corresponding locating face of position shelf, attachment face, the inclined-plane, location, one boss that matches with above-mentioned boss is also arranged on the locating face of scaffold, hypotenuse direction on this boss is identical with aforementioned hypotenuse, at the attachment face of scaffold, each fixes a nut on the inclined-plane, location, and is corresponding with two mounting holes respectively, when mounted, scaffold inserts in the position shelf, has two bolts to pass mounting hole respectively and cooperates with nut, and two rod members are connected.

Have the location that cooperatively interacts, two pairs of inclined-planes on the utility model.When bolts and nuts connected position shelf and scaffold together, inclined-plane, two location cooperatively interacted, and the true dip direction of rod member to the inclined-plane, location that has scaffold is close to; And two hypotenuses cooperatively interact, the rod member of band scaffold is close to the true dip direction of hypotenuse, add the positioning action of confined planes, so accurately locate in the space between rod member when the utility model has been realized the rod member interconnection, can be in order to set up out similar structure such as accurate framework in position or canopy.The utility model is simple in structure in addition, firm, characteristics such as easy accessibility.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, be fixed with position shelf 3 in the utility model on the rod member 1, be fixed with scaffold 4 on another rod member 2, locating face 5 is arranged on the position shelf 3, attachment face 6, inclined-plane 7, location, locating face 5 is relative with inclined-plane 7, location, confined planes 9 is vertical with aforementioned three faces, the boss 51 that one band hypotenuse 52 is arranged on the locating face 5, on attachment face 6 and the inclined-plane 7, location a mounting hole 61 is arranged respectively, 71, have on the scaffold 4 and position shelf 3 corresponding locating faces 5 ', attachment face 6 ', inclined-plane 7 ', location, one boss 51 ' that matches with above-mentioned boss 51 is also arranged on the locating face 5 ' of scaffold, hypotenuse 52 ' direction on this boss 51 ' is identical with aforementioned hypotenuse 52, attachment face 6 ' at scaffold, inclined-plane, location 7 ' is gone up each and is fixed a nut 61 ', 71 ' respectively with

mounting hole

61,71 correspondences, when mounted, scaffold 4 inserts in the position shelf 3, and two bolts 8 are arranged, 8 ' passes mounting hole 61 respectively, 71 with nut 61 ', 71 ' cooperates, and makes two rod members 1,2 connect.For the ease of making and installing, attachment face 6 in the utility model on the position shelf 3 is vertical with locating face 5, correspondingly there is attachment face 6 ' vertical on the scaffold 4 with locating face 5 ', and above-mentioned two boss 51,51 ' are all at right angles trapezoidal, and wherein trapezoidal hypotenuse 52,52 ' tilts to confined planes 9 directions.
