Football door doorframe

Abstract

The invention discloses a football door doorframe. The doorframe comprises two columns, a beam is arranged between the columns, each of the two ends of the beam are connected with each of the tops of the columns through a joint respectively, both of the end surfaces of the ends of the beam are vertical flat surfaces which are perpendicular to the axis of the beam, and each of the top end surfaces of the columns is a horizontal flat surface which is perpendicular to the axis of the corresponding column; the joints comprise joint bodies, horizontal connecting joints and vertical connecting joints are arranged on the joint bodies, each of the horizontal connecting joints is perpendicular to each of the vertical connecting joints, so that the joints are L-shaped, the horizontal connecting joints are arranged in connecting cavities on the end portions of the beam in an embedded mode and connected with the beam through bolts, and the vertical connecting joints are arranged in the connecting cavities on the tops of the columns in an embedded mode and connected with the columns through the bolts. The football door doorframe has the advantages that the connecting performance is good, processing is simple, the cost is low, space usage is low, and logistic transportation is convenient.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a door frame structure on a football goal. Background technique [0002] Soccer goal is an indispensable kind of sports equipment in football. The structure of the football goal frame currently used is as follows: it includes two columns, and a beam is arranged between the two columns. connected at the top. The Chinese invention patent application with the patent number of 200710131717X discloses a mounting structure for the beam and the column in the football goal. Connection, the joint is composed of a horizontal plug-in and a vertical plug-in, the horizontal plug-in and the vertical plug-in are perpendicular to each other, the horizontal plug-in is embedded in the connection cavity at the end of the beam and connected to the beam through bolts, and the vertical plug-in is embedded in the connection cavity at the top of the column and connected with the column by bolts. The b...

AI Technical Summary

Problems solved by technology

The beams and columns of this structure take up a lot of space, which is not conducive to logistics transportation. In the actual processing process, there will inevitably be machining errors, so it is difficult to ensure that the end faces of both ends of the beam and the top end of the column are 45° inclined. , the processing precision of both end faces of the beam and the end face of the column top is very high, the processing is cumbersome and consumes materials, which greatly increases the cost. Some joints are exposed outside and cannot be completely wrapped in the connection cavity between the beam and the column, the connection is unreliable, and there are potential safety hazards
