Abstract

The utility model relates to an extension pipe connecting piece, which comprises a connecting piece body. The interior sidewall of the connecting piece body is provided with clamping rings with a plurality of projections. The fixed end handle of the connecting piece body is provided with a plurality of fixed holes. The connecting piece body adopts a cylindrical structure and the two ends of the connecting piece body are provided with openings. According to the utility model, when the lengths of members, such as a scaffold tube, a support top, a support column and the like, need to be prolonged, two pipes are respectively arranged on the extension pipe connecting piece and then are fastened through screws. The periphery of each pipe is provided with a plurality of channel sections and the connecting piece is provided with three clamping rings. Therefore, the two pipes and the connecting piece are respectively and correspondingly installed. After the two pipes are connected with the connecting piece, the pipes are not easy to loose and are fastened more tightly.

Description

A kind of extension connector

Technical field

The utility model relates to building materials field, relates in particular to a kind of extension connector.

Background technology

At building materials field; A lot of construction brackets all need extend lengthening according to the different demands under the different situations; For example; Scaffold is meant the job site for workman operation and solve the vertical various supports that transportation is set up with level, is mainly that the constructor works up and down or maintenance of peripheral safety net and high-altitude installation component etc., must satisfy the performance of aspects such as under various conditions intensity of building structure and member, rigidity, stability; It is pointed out that when the length of members such as scaffold tube, a top, support column need prolong, then need extra assembly to accomplish; Present existing extension assembly when mounted, two bodys are easy to generate loosening phenomenon after connection, integral body is fastening inadequately, therefore, need reasonably improve prior art.

The utility model content

To above defective, the utility model provides a kind of and has card muscle structure, connects extension connector firm, easy accessibility, to solve many deficiencies of prior art.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of extension connector comprises the connector body, and the inboard wall of said connector body is offered the card muscle of some convexities, offers the plurality of fixed hole on the said connector body-fixed end handle; Said connector body is the cylindrical structure of both ends open.

The beneficial effect of the described extension connector of the utility model is: when the length of members such as scaffold tube, top, support column needs overtime, can respectively two pipes be installed on the extension connector, and then carry out fastening with screw; Have some draw-in grooves around the body, and have three card muscle on the extension connector, therefore can distinguish corresponding the installation, after two pipes connect, be not easy to become flexible, more fastening.

Description of drawings

According to accompanying drawing the utility model is done further explain below.

Fig. 1 is the application state sketch map of the said extension connector of the utility model embodiment;

Fig. 2 is the lateral view of the said extension connector of the utility model embodiment;

Fig. 3 is the sketch map of the band vertical setting of types fixing hole of the said extension connector of the utility model embodiment;
