Abstract

The utility model belongs to stationary members, which realizes an anchor ear for connection between pipes, and thus the field installation, connecting and fixation of a pipe class can be conveniently operated. The utility model is composed of at least three clamping bands (1) and detachable connecting pins (2), wherein, both ends of each clamping band (1) are provided with connecting heads (3) on which connecting pin holes (5) are arranged; the detachable connecting pins (2) can penetrate the connecting pin holes (5) to fix the connecting heads which are butted with the clamping bands (1), and thus at least three clamping bands (1) are connected into anchor ear integration with a belt and a buckle. One of the detachable connecting pins (2) is detached or assembled, and thus the periphery of the anchor ear integration with a belt and a buckle can be conveniently opened and closed; pipes can be connected and fixed rapidly in very narrow space; the utility model has easy installation and high efficiency.

Description

Bracelet formula anchor ear

The utility model belongs to the member that is connected and fixed between pipe.

Being connected and fixed between the tubing often realized by the fixed tube joint edges.Especially be fixed with gas, the liquid pipe of seal request, assemble earlier the frame in a plurality of housing screws hole often, during installation interface tube is docked, pass the screw hole of interface tube two frames with screw at the interface tube place, tighten nut again so that between pipe connection solid.Because of accumulated error behind the pipeline spreading is big, cause pipeline docking port frame screw hole mutual dislocation serious; And piping erection is on-the-spot, and the space is narrow and small mostly, situation is complicated, and the scene is adjusted or punched in place very difficult.The inconvenience of the solid construction of connection is usually incured loss through delay the duration between piping erection, pipe, and installation quality is also influenced.

The purpose of this utility model is, realizes connecting firmware between a kind of bracelet formula pipe, makes the scene installation connection of tubing solid easy to operate.

The utility model is made up of clip and detachable attachment pegs, said clip has three at least, the two ends of each clip are coupling heads, connecting hole is arranged in the coupling head, said detachable attachment pegs can penetrate the coupling head that connects the fixing butt joint of pin-and-hole clip, make at least three clips be unified into bracelet formula anchor ear, also can pull down from connecting pin-and-hole.

The said detachable attachment pegs of the utility model, can the part or by all forming by screw (bolt) and nut, the interior cross section of said clip is " U " shape, its opening is towards the interior sky of described anchor ear, forming clip inner edge empty in the anchor ear can be lineal shape, also can be camber line shape, week can be a polygonal in the promptly said bracelet formula anchor ear, also can be circular arc.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the opening and closing schematic representation of rectangular band button anchor ear;

Fig. 2 is the opening and closing schematic representation of circular bracelet formula anchor ear;

Fig. 3 is the A-A view of Fig. 1, Fig. 2.

Among Fig. 1,1-clip, 2-detachable attachment pegs, 3-coupling head, 5-connection pin-and-hole;

Among Fig. 2,1-clip, 2-detachable attachment pegs, 3-coupling head, 5-connection pin-and-hole;

Among Fig. 3,1-clip, 4-" U " shape grooves.

Embodiment 1: embodiment 1 is made of Fig. 1 and Fig. 3.

As Fig. 1, shown in Figure 3, rectangular band button anchor ear has four clips (1) and four detachable attachment pegs (2), and the inner edge of clip (1) is a lineal shape, and interior cross section is " U " shape; Detachable attachment pegs (2) is made up of screw, nut, and it can penetrate the coupling head (3) that connects pin-and-hole (5) fixing butt joint clip (1).During on-the-spot the installation, it is big to butt joint to join two solid rectangular tube interfaces earlier, look field condition and pull down a certain detachable attachment pegs (2) of rectangular band button anchor ear, open corresponding one or two clips (1), load onto anchor ear as " wearing a girdle " along the interface tube edge, the clip that returning is opened (1), allow the interface tube edge all embed in clip (1) inner edge " U " the shape groove (4), detachable attachment pegs (2) is reinstalled connection pin-and-hole (5), tighten up fourth officer joint bolt, nut (2), installation.From the utility model periphery arbitrary detachable attachment pegs (2) opening and closing clip (1), just can easily anchor ear " button " be gone into and fastening two butt joint mouth of pipe edges, also be easy to operation, installation efficiency height at utmost point narrow space; And the interface tube edge embed in " U " shape groove (4) of clip (1) inner edge fastened after, sealing and vibration resistance are fabulous, also need not when adding the interface tube frame to hole.

Embodiment 2: embodiment 2 is made of Fig. 2 and Fig. 3.

As Fig. 2, shown in Figure 3, circular bracelet formula anchor ear has three clips (1) and three detachable attachment pegs (2), and the inner edge of clip (1) is a circular arc, and interior cross section is " U " shape; Detachable attachment pegs (2) is made up of screw, nut, and it can penetrate the coupling head (3) that connects pin-and-hole (5) fixing butt joint clip (1), makes three clips (1) be connected into circular bracelet formula anchor ear integral body.
