Problems solved by technology

Most of the connecting mechanisms used in the existing assembly are screw connections, but for the sake of beautiful appearance, the screws must not be exposed during installation. At the same time, due to the limitation of the processing mold, threaded holes cannot be set on the connection parts of the sofa. Therefore, the existing technology It is to open a through hole at the connection part of the product first, and then set up a spacer with a threaded hole. There are undercuts on both sides of the spacer, and the undercut is stuck on the connection part of the product. The threaded hole corresponds to the passage. Insert the screw into the through hole and tighten the threaded hole, the installation is very troublesome
Especially when inserting, it is easy to break the undercut on the pad, resulting in the scrapping of the entire pad

Embodiment Construction

[0017] The invention relates to an integrated thread connection mechanism for a combined sofa, such as figure 1 — Figure 4 As shown, it includes a seat board 1, a back board 2, a front board 3, a rear board 4, a left board 5, a right board 6, and a left board 5, a right board 6 and a seat board by injection molding of plastic materials. 1. The backboard 2, the front baffle 3, and the rear baffle 4 are assembled and connected by a connecting mechanism. The connecting mechanism includes setting hollow columns 7 on both sides of the left buttress 5 and the right buttress 6. A connecting column 8 is arranged on the inner side wall of the column, and a connecting hole 10 is opened in the connecting column. An integrally formed thread 11 is arranged in the connecting hole. The thread 11 has only one spiral, and there is a fracture between the beginning and the end of the spiral. 12. A hollow groove 13 is provided on the rear side wall of the left buttress 5 and the right buttress ...

Abstract

A combination sofa integrated threaded connection mechanism comprises a seat plate, a back plate, a front retainer, a rear retainer, a left armrest plate, and a right armrest plate which are made witha plastic material by injection molding. The left armrest plate, the right armrest plate, the seat plate, the back plate, the front retainer and the rear retainer are fixedly assembled and fixed through a connection mechanism. The connection mechanism includes hollow pillars arranged on the two sides of the left armrest plate and right armrest plate respectively; a connection post is arranged onthe inner wall of each hollow pillar; a connection hole is arranged in each connection post; a screw threaded is integrally formed in each connection hole; a gap is arranged between the start and stopof each screw thread; the rear walls of the left and right armrest plates, corresponding to the screw threads, are provided with through channels; the assembly connections of the seat plate, the backplate, the front retainer, the rear retainer, the left armrest plate and the right armrest plate are provided with corresponding through holes; the through holes are fixedly connected with the connection holes having the screw thread through plastic screws.

Description

technical field [0001] The invention relates to a combined sofa integral thread connection mechanism and a processing mold for processing the integral thread. Background technique [0002] At present, there are many combined sofas on the market. The advantage is that they are molded by separate injection molding of plastic materials, and then assembled together by connecting mechanisms. The cost is low and the processing speed is fast. They can be placed on balconies, outdoors, parks, beaches and other places. , was welcomed. Most of the connecting mechanisms used in the existing assembly are screw connections, but for the sake of beautiful appearance, the screws must not be exposed during installation. At the same time, due to the limitation of the processing mold, threaded holes cannot be set on the connection parts of the sofa. Therefore, the existing technology It is to open a through hole at the connection part of the product first, and then set up a spacer with a thre...
