Abstract

The invention discloses a plug-in self-tapping threaded connecting device special for skirting type radiator field. The device comprises a self-tapping threaded joint, wherein the self-tapping threaded joint consists of a plug-in joint, a threaded joint, a fastening point and a self-tapping thread; the self-tapping thread is arranged on one side, close to the plug-in joint, of the fastening point;the self-tapping threaded joint is used for connecting a pipeline fixed on a radiating panel by rotating the self-tapping thread during installation; a plurality of sealing grooves are formed in theouter wall of the self-tapping threaded joint; and sealing rings are wrapped with the sealing grooves. According to the device, the self-tapping threaded joint is used for connection, so that the technical problem that the precision of on-site limiting and fixing is difficult to control is well solved, and the phenomena of corrosion and leakage caused by damage to a skirting type radiator body caused by thread machining are thoroughly avoided.

Description

technical field [0001] The invention belongs to the technical field of baseboard ring heating, and relates to a plug-in self-tapping screw connection device used in the technical field. Background technique [0002] Most of the water pipes between baseboard radiators are connected by threads, that is, the water pipes of baseboard radiators are internal threads, which are connected with special parts of external threads in a rotating and sealed manner. The internal thread of the pipeline needs to be pre-processed, so the processing cost and processing difficulty are increased, and it is not convenient for on-site installation. [0003] In order to overcome technical defects such as the need to process internal threads on the water pipes, which is not conducive to on-site installation, affects installation efficiency, and affects sealing performance, the applicant submitted the application in the previous period (a new type of baseboard-type self- Sealed wire connection devic...
