The application relates to the field of stainless steel pipe connection, and discloses a stainless steel pipe connection sealing mechanism, which comprises two stainless steel pipes and a connecting head arranged between the two stainless steel pipes. Inner thread assembly grooves are arranged on the left and right sides of the connecting head. A same communication hole is arranged on the inner wall of the side, where the two inner thread assembly grooves are close to each other. The ends, where the two stainless steel pipes are close to each other, respectively penetrate through the corresponding inner thread assembly grooves and extend into the communication hole. Bearings are fixedly sleeved on the two stainless steel pipes. The outer rings of the two bearings are fixedly sleeved with outer thread sleeves. The application has the following advantages and effects: multiple sealing between the two stainless steel pipes and the connecting head can be realized, the sealing performance of the connection part of the two stainless steel pipes can be ensured through the synergistic effect of multiple sealing, the omnibearing sealing effect is realized, and the application is suitable for fluid conveying scenes with strict sealing requirements.

This application relates to the field of equipment assembly components technology, and discloses a quick-release assembly and electronic device. The quick-release assembly includes a first connecting seat fixedly connected to a first assembly and a second connecting seat fixedly connected to a second assembly. A connecting block on the second connecting seat is inserted into a connecting hole on the first connecting seat. A locking member is slidably disposed on the first connecting seat, and an elastic member abuts against the locking member and the first connecting seat. Under the elastic force of the elastic member, the locking member clamps the connecting block in the connecting hole, thereby fixing the first assembly and the second assembly. An unlocking member is disposed on the first connecting seat, and the unlocking member is kinetically connected to the locking member. The unlocking member provides a first force to the locking member, causing the locking member to release the clamping of the connecting block, thereby allowing the first assembly and the second assembly to be detachably separated. Through the above method, rapid assembly and disassembly between the two assemblies are achieved, and the connecting block can be stably clamped and fixed in the connecting hole.

The utility model relates to the technical field of optical fiber coupler, especially a kind of easily connected coupler, including connecting end, the connecting end includes two-way shell and connecting inner shell, the connecting inner shell is symmetrically installed in two-way shell both ends inner side, and connecting inner shell is fixedly connected with two-way shell, the both ends of two-way shell are equipped with the plug connector of cooperation, the outside surface of plug connector is provided with several snap fittings with two-way shell cooperation, and still be equipped with the push plate piece of cooperation with snap fitting on plug connector. The coupler of the application is matched by snap fitting and push plate piece, realizes simple and convenient connection and disassembly operation, does not need additional tool, greatly improves the efficiency of installation and maintenance. The reasonable design of two-way shell and plug connector and the close cooperation of snap fitting and longitudinal slot ensure the stability of coupler connection, which can effectively prevent loosening phenomenon in use.
