Type of sliding door railing

A sliding door railing, including a door railing body, a first connecting mechanism, and a second connecting mechanism, the first connecting mechanism and the second connecting mechanism are fixed at intervals in opposite in an installation position, one side of the door railing body is detachably and pivotally connected to the first connecting mechanism, and one side of the door railing body far away from the first connecting mechanism is detachably and pivotally connected to the second connecting mechanism;

• wherein an upper left end and a lower left end of the door railing body are detachably and pivotally connected to an upper end and a lower end of the first connecting mechanism, and an upper right end and a lower right end of the door railing body are detachably and pivotally connected to an upper end and a lower end of the second connecting mechanism, respectively;
• wherein the first connecting mechanism comprises a first upper seat and a first lower seat that have a first push button, a bottom of the first upper seat and a top of the first lower seat are respectively provided with a first socket and a second socket;
• and a first expansion member is movably provided at a position where the door railing body is assembled with the first upper seat, the first expansion member can, relative to the door railing body, move between a position where it partially extends into the first socket and a position where it exits the first socket, and a first top spring is further provided to apply elastic force to cause the first expansion member move in a direction in which the first expansion member can partially extend into the first socket;
• a second expansion member is movably installed at a position where the first lower seat is assembled with the door railing body, the second expansion member can, relative to the door railing body, move between a position where it partially extends into the second socket and a position where it exits the second socket, and a second top spring is further provided to apply elastic force to cause the second expansion member move in a direction in which the second expansion member can partially extend into the second socket;
• the first socket extends to a top of the first upper seat that runs through the first upper seat, and a first pressure piece is movably installed on an upper end of the first socket, the first pressure piece can perform vertical reciprocating motion along the first socket to force the first expansion member to exit the first socket or move away from the first expansion member, the first push button can move, relative to the first upper seat, between a position where it locks the first pressure piece and a position where it unlocks the first pressure piece;
• the second connecting mechanism includes a second upper seat and a second lower seat that have a second push button, a bottom of the second upper seat and a top of the second lower seat are respectively provided with a third socket and a fourth socket, a third expansion member is movably installed at a position where the second upper seat is assembled with the door railing body, the third expansion member can, relative to the door railing body, move between a position where it partially extends into the third socket and a position where it exits the third socket, and a sixth top spring is further provided to apply elastic force to cause the third expansion member move in a direction in which the third expansion member can partially extend into the third socket;
• a fourth expansion member is movably installed at a position where the second lower seat is assembled with the door railing body, the fourth expansion member can, relative to the door railing body, move between a position where it partially extends into the fourth socket and a position where it exits the fourth socket, and a seventh top spring is further provided to apply elastic force to cause the fourth expansion member move in a direction in which the fourth expansion member can partially extend into the fourth socket;
• the third socket extends to a top of the second upper seat, and a second pressure piece is movably installed on an upper end of the third socket, the second pressure piece can perform vertical reciprocating motion along the third socket to force the third expansion member to exit the third socket or move away from the third expansion member, the second push button can, relative to the second upper seat, move between a position where it locks the second pressure piece and a position where it unlocks the second pressure piece.
