Description

Profiled bolt connecting seat

Technical Field

The utility model relates to a connection structure between the body, especially a die mould bolted connection seat.

Background

The connection between the existing pipe body and the pipe body, such as the truss structure, is formed by connecting a plurality of transverse and longitudinal pipe bodies (or rod bodies), and in order to improve the structural stability, the existing truss structure usually connects the pipe bodies which are adjacently and horizontally arranged through end flanges, and the welding is directly adopted between the transverse pipe body and the longitudinal pipe body or between the inclined pipe body and the transverse and longitudinal pipe bodies. Because the end part of one pipe body is required to be connected with the pipe body of the other pipe body when the transverse pipe body and the longitudinal pipe body or the inclined pipe body and the transverse pipe body and the longitudinal pipe body are connected, if a threaded connection structure is adopted, flange connection is usually arranged, if a horizontal flange plate is adopted, the horizontal flange plate cannot be tightly attached to the pipe body, and the connection strength can be greatly reduced; if it is to set up an arc flange welding on the pipe shaft of a body, then the tip at another body sets up horizontal flange, so can't closely cooperate between horizontal flange and the flange to be connected, because one is the arc, one is the plane board, hardly laminate, it improves intensity to establish the arc flange board in addition on the pipe shaft by increasing flange plate thickness, be not to improve intensity by the structure of self, and not only with high costs, the flange board bodiness is still difficult for designing into the arc, lead to processing to waste time and energy.

Detailed Description

The invention will be described in further detail with reference to the drawings and specific examples.

As shown in fig. 1 and 2: the utility model provides a die mould bolted connection seat, connects between adjacent body 1, includes die mould spiral shell seat 2, die mould spiral shell seat 2 is connected on the shaft 11 of a body, and is connected with the laminating of shaft 11, and this body 1 carries out the thread tightening through die mould spiral shell seat 2 and the connecting piece on another body.

The scheme has the following advantages: on one hand, the profiled screw seat of the embodiment is particularly suitable for being connected with a pipe body, but not connected with the end part of the pipe body, and is attached to the pipe body, so that the contact area between the profiled screw seat and the pipe body can be greatly increased, and further the connection strength is improved, therefore, the profiled screw seat is arranged in the embodiment, the profiled screw seat is formed into a structural member through compression molding, the mechanical property of the structure is good, the thickness of the plate body of the profiled screw seat can be thinner due to tight attachment, and compared with the traditional connecting piece, the profiled screw seat of the embodiment increases the strength by the thickness, and the profiled screw seat of the embodiment can increase the strength by the structure; on the other hand, current body end and body are connected and are directly adopted the welding usually, and this kind of mode is unfavorable for reuse, and installation rate is slow, and the body of this embodiment can be installed fast and dismantle, and can used repeatedly after dismantling.

It is understood that the tubular body 1 of the present embodiment may be a tube, a rod or a column, and the sectional shape thereof may be circular, elliptical or polygonal. The connecting piece can be a flange plate or other connecting plates. The following specifically exemplifies a hollow circular tube and a flange plate.

Between adjacent body 1, the tip welding of a body has flange plate 3, and the pipe shaft of another body is equipped with die mould spiral shell seat 2, and perpendicular or be certain angle setting between the continuous body 1. When the pipe body is connected in an angle mode, the end portion of the pipe body can be designed to be welded in a mode that the inclined plane is parallel to the flange plate. The application of this embodiment is applicable to the connection between various pipes, such as a truss structure, which is generally composed of a plurality of pipes. When longitudinal and transverse body coupling, just accessible the profiled bolted connection seat of this embodiment is connected.

Specifically, the profiling screw seat 2 includes an abutting surface 21 adapted to the pipe body and a connecting surface 22 extending along the abutting surface. Wherein, binding face 21 is the arcwall face, with body of tube 11 looks adaptation, and binding face 21's area can be big or small, even a small part, also can improve area of contact. The central angle of the bonding surface 21 corresponding to the arc is preferably 15 to 60 °. The two ends of the binding surface 21 of the profiling screw seat 2 are bent to form a connecting surface 22, a connecting hole 23 is arranged on the connecting surface 22, and after the flange plate 3 on the other pipe body is matched and connected with the connecting surface, the connecting hole of the connecting surface and the connecting hole on the flange plate are oppositely arranged. The connecting surface 22 of the present embodiment is a horizontal surface formed by bending the plate body upward along the attaching surface 21 and extending to both sides. In order to further strengthen the joint strength between die mould spiral shell seat 2 and the body of pipe 11, the plate body die mould goes out binding face 21 and is connected the face 22 after, still follow the side of connecting the face and continue bending downwards, form the border 24 of bending similar to the S type, the lower part and the body of pipe 11 laminating of border 24 of bending are connected, binding face 21 and the border 24 of bending of die mould spiral shell seat 2 all with body of pipe 11 welded fastening promptly, can improve area of contact greatly like this, the atress is stable, and the die mould bolt is bent many times, improve self intensity greatly, can be with the thinner of the plate body thickness design of die mould spiral shell seat 2.
