However, in the practical application process of the connector, the self-sealing connecting device needs to be fixed on the skirting line type heat sink by using rivets or other methods, so as to avoid displacement, deformation and the like caused by thermal expansion and cold contraction. Undoubtedly, the use of rivets and other butt joints is fixed during field installation, and the field fixation can increase the installation difficulty because the difficult control problem of precision to influence installation effectiveness, increase installation cost, influence market competition. For this reason, a more convenient connection device is required.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a connect with the on-the-spot installation more swiftly convenient and skirting line type radiator that sealing performance is good adopt warm dedicated formula self tapping threaded connection device of inserting promptly in field.
In order to solve the technical problem, the utility model relates to a special formula self tapping threaded connection device that inserts promptly in skirting line type radiator field, including self tapping screw thread formula joint, self tapping screw thread formula joint comprises formula joint, screwed joint, fastening point and self tapping screw thread of inserting promptly, self tapping screw thread sets up the one side that is close to formula joint promptly at the fastening point, self tapping screw thread formula joint will be fixed in the pipeline of skirting line type radiator and connect through rotatory self tapping screw thread when the installation, be equipped with a plurality of seal grooves on self tapping screw thread formula joint's the outer wall, the sealing washer wrap in the seal groove.
On the basis of the technical scheme, the outer diameter of the self-tapping thread is larger than the outer diameter of the joint body and larger than the inner diameter of a pipeline installed on the heat dissipation panel.
Further, the seal groove is located near an opening end of the self-tapping screw joint.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a water pipeline uses self tapping screw thread formula to connect, and self tapping screw thread will be fixed in the pipeline on the heat dissipation panel through the rotation and connects, plays good fixed action, need not to use separately and carries out spacing fixed to the pipeline connector such as rivet, has solved the difficult technical problem who controls of the precision of on-the-spot spacing fixed betterly.
The utility model discloses need not to process the screw thread in the pipeline mouth of pipe inboard to thoroughly avoided causing the skirting line type radiator body to damage when processing the screw thread and lead to the emergence of phenomenons such as corruption, leakage, also avoided when the installation because of the damage effect of mouth of pipe screw thread to the sealing washer.
The utility model discloses not only convenient operation is swift, does benefit to the field installation, has practiced thrift the processing cost, has improved the installation effectiveness greatly, and sealing performance is good moreover, has reduced the emergence of situations such as interface seepage greatly.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural view of a dedicated plug-in self-tapping threaded connection device for a skirting line type radiator of the present invention;
fig. 2 is a schematic structural diagram of a special self-sealing wire-aligning connecting device in the field of novel skirting line type heating in the background art.
Detailed Description
As shown in fig. 1, a formula self tapping threaded connection device is inserted promptly in skirting line type radiator field special use, including self tapping screwed joint 4, self tapping screwed joint 4 comprises formula of inserting promptly joint 41, screwed joint 42, fastening point 43 and self tapping screw 45, self tapping screw 45 sets up the one side that is close to formula of inserting promptly joint 41 at fastening point 43, self tapping screwed joint 4 will be fixed in pipeline 31 on radiator panel 3 through rotatory self tapping screw 45 and connect when the installation, be equipped with a plurality of seal grooves on self tapping screwed joint 4's the outer wall, sealing washer 44 wraps up in the seal groove. The outer diameter of the tapping screw 45 is larger than the outer diameter of the body of the joint 4 and larger than the inner diameter of the pipe 31 attached to the heat radiation panel 3.
The utility model discloses pipe connection and fixed mounting are convenient, when carrying out the pipe connection, to insert formula joint 41 promptly and be fixed in the pipeline 31 on the cooling panel 3 in, sealing washer 44 supports tightly with pipeline 31 inboard, it is tight to offset screwed joint 42 and coupling hose's mouth of pipe department, through the rotatory self tapping screw thread 45 of fastening point 43, self tapping screw thread 5 produces the internal thread in 31 mouth of pipe 32 departments of pipeline, thereby self tapping screw thread formula connects 4 and carries out spacing fixed with pipeline 31, need not to use fixed pipe joints such as rivet separately, do benefit to the on-the-spot installation concatenation, and the installation cost is saved.
