Description

Novel connecting joint

Technical Field

The utility model relates to a body installation field to more specifically relates to a novel attach fitting.

Background

In our daily life, for example, guard rails, display shelves, bookshelves, shoe shelves, and the like, such as those made of tubular bodies that are overlapped, a connection joint for connecting more than two tubular bodies is generally used.

application number is CN201220450192.2, and the patent name is attach fitting's an attach fitting, a serial communication port, including a bearing body, be provided with two at least screws on the bearing body, be provided with the bolt in the screw, the cover is equipped with the cuff that expands gradually after the extrusion on the screw rod section that the bolt stretches out the screw, the cuff presss from both sides between the nut of bearing body and bolt, beneficial effect: (1) the utility model discloses it is very convenient to install, only need with the connecting pipe cover at the cuff periphery, rotatory screw, extrusion cuff for the cuff inflation, thereby with connecting pipe inner wall interference fit. (2) The utility model discloses the suitability is also very extensive, no matter be the elbow connect, directly, still three pipe joints, four-pipe joint, only need select the screw of corresponding angle on the supporting body to install just. This connection has the following drawbacks: (1) the connector is formed by splicing two cuffs, the installation is troublesome, the production cost is high (2), after the bolt and the cuffs are installed without the gasket (3), the expansion of the cuffs is close to the limit, and if the cuffs expand due to high temperature and other reasons, the cuffs are easy to break.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel attach fitting, low in production cost, it is simple convenient to install, and is safer moreover.

In order to solve the technical problem, the utility model relates to the field of pipe body installation, in particular to a novel connecting joint, which comprises a bearing body, a connecting hoop, a supporting sleeve and a bolt, wherein the connecting hoop is provided with a sleeve piece I, a sleeve piece II and a notch; the supporting sleeve is provided with a through hole, a gasket cover and a sleeve body; the connecting hoop is connected with the supporting sleeve in a sliding mode, the inner wall of the connecting hoop is in contact with the sleeve body on the supporting sleeve, the bolt is inserted into the through hole of the supporting sleeve and is connected with the supporting sleeve in a sliding mode, and the bolt is in threaded connection with the bearing body.

As the further technical optimization of the technical proposal, the utility model relates to a novel connection joint the inner wall diameter of the connection hoop and the diameter of the sleeve body on the supporting sleeve are equal.

As the further technical optimization of this technical scheme, the utility model relates to a novel attach fitting external member I and external member II on be equipped with the fin that rises.

As the further technical optimization of this technical scheme, the utility model relates to a novel attach fitting II on the rise piece on be equipped with the shrinkage joint.

Further technical optimization as this technical scheme, the utility model relates to a novel attach fitting the threaded diameter of bolt and the through-hole inner wall diameter of supporting the cover equal.

The utility model relates to a novel attach fitting's technique compares with prior art, has following beneficial effect: (1) the hoop is a whole, the installation is simple and convenient, and the production cost is low. (2) The sleeve hoop is provided with the contraction joint, so that the expansion coefficient of the sleeve hoop is improved, and the sleeve hoop is safer. (3) The support sleeve acts as a washer between the threads and the ferrule.
