Abstract

The utility model relates to a connector with an arc convex used in a composite supporter. Presently people often sleeve or connect supporting tubes into a composite supporter, and mostly connecting parts with thread at both ends or connecting elements provided with ring-slot spacers are adopted in the connecting points, for the sake of short length and poor rotating connecting elements of connecting elements, the composite supporter tends to deform and impact the service life. The utility model is a pipe shaped metal or other material, the middle part is provided with two convexes, which have an outer diameter with the same size as that of the supporting pipe of the supporter. The middle parts of both ends are provided with thread to connect the thread of the inner walls of the supporting pipes of the supporter. A cut is respectively opened at the top parts of both ends to facilitate an object such as a metal rod to insert thereto and firmly screw the connecting points. The utility model has the advantages of being convenient and labor saving to use, not impairing the whole appearance of the connecting points, good combining strength, firmness, precision and low production cost, being easy to be assembled and dismantled. Furthermore, the utility model can also be used in the connecting of assembling furniture or other pipes, which is universally used and of good practicality and be convenient to be popularized.

Description

A kind of assembled shelf connector that has arc-shaped convex

Technical field

The utility model relates to a kind of assembled shelf connector.

Background technique

The present employed assembled shelf of people, assemble by support tube and glove net etc., connection between the support tube, usually the link mode that adopts two ends to be designed to the link of screw thread or the annular groove partition is set spins, connector is shorter, the intensity that spins is relatively poor, makes the assembled shelf distortion easily, influences working life greatly.

The model utility content

The purpose of this utility model be to provide a kind of easy to assembly, adhesive strength is high, firmly accurately, the assembled shelf connector of long service life.

The utility model is metal or other material tubulose, its middle part is provided with arc-shaped convex, external diameter is identical with the rack support tube external diameter that is connected, the middle part, two ends respectively is provided with screw thread, with the rack support tube internal whorl that the is connected coupling that spins mutually, at the top, two ends, be provided with gap, can be symmetrical arranged, also can be set to 1 to several, when spinning, can insert instrument such as metallic rod at opening position and help to spin with the rack support tube, with enhancing spin intensity and tightness, and screw in, screw out when helping dismounting.

Advantage of the present utility model is, and is convenient, laborsaving during use, do not influence the overall appearance of connection part, adhesive strength height, firmly accurately, and cost of production is low, is convenient to the dismounting and the transportation of assembled shelf, also can apply to sectional furniture etc. simultaneously, is beneficial to popularization.

Fig. 1 is an overall structure schematic representation of the present utility model;

Fig. 2 is a generalized section of the present utility model.

1 is connector among the figure, the 2nd, and arc-shaped convex, the 3rd, screw thread, the 4th, gap.

Specific embodiment

The utility model is described in further details with most preferred embodiment below in conjunction with accompanying drawing:

The utility model is a tubular metal, its middle part is provided with the external diameter arc-shaped convex (2) identical with the rack support tube external diameter that is connected, the middle part, two ends respectively is provided with screw thread (3), be complementary with the screw thread in the rack support tube port of institute's socket, at the top, two ends, can have the gap (4) of two symmetries.During use, the end of this connector (1) is spun mutually with rack support tube one end that needs to connect, can locate to insert metallic rod in gap (4) and help to screw, another root rack support tube is spun mutually with the other end of connector (1) gets final product then.
