Slide rail structure

A slide rail structure, comprising:

• a slide rail body, comprising a fixed rail, an extension rail sliding along the fixed rail, and a telescopic rail sliding along the extension rail;
• an end of the fixed rail is provided with a blocking part, and a combination part is provided in a non-end position of the fixed rail;
• both sides of the fixed rail are provided with two insertion holes corresponding to the combination part;
• a groove is recessively formed on a bottom surface of the extension rail along a forming direction;
• the groove is provided with an inward-pushing protrusion relative to the combination part of the fixed rail, and a through hole is provided adjacent to the inward-pushing protrusion;
• and
• a locking unit, comprising a locking seat, a latch, at least one locking plate, and a locking spring;
• the locking seat is installed on the combination part of the fixed rail, and a thickness of the locking seat is smaller than a depth of the groove, so as to allow the extension rail to slide and displace along the fixed rail;
• the locking seat has a guide groove for slidingly installing the latch;
• the locking seat forms a stop toward the front end of the fixed rail and forms an opening toward the other end of the fixed rail;
• the opening has a guide slope, and an upper surface of the locking seat is provided with a hollow portion from the opening to a middle position, and two lock sockets are provided on both sides of the locking seat corresponding to the two insertion holes connecting with the guide groove;
• an outer push portion and an inner push portion are protruding from a surface of the latch, and both the inner push portion and the outer push portion are introduced into the hollow portion and are lower than the upper surface of the locking seat;
• the locking plate is inserted between the two insertion holes of the slide rail body;
• both ends of the locking plate are formed a guide inclined end, the guide inclined end is inserted into the lock socket of the locking seat and connected with the latch to form the locked/unlocked states of the slide rail body;
• the locking spring is installed in the groove of the extension rail, the locking spring has a raised slope facing the through hole, and the end of the raised slope is bent downward to form a leading end, and a center of the leading end is concave to form an extrapolated top.
