Description
Technical Field
The invention relates to the technical field of sliding rails, in particular to a locking structure of a sliding rail.
Background
The slide rail is used for connecting two objects which can move relatively. The sliding rail structure is widely applied to server erection, at present, the structure of the existing sliding rail is generally formed by connecting an inner rail, a middle rail and an outer rail, the inner rail, the middle rail and the outer rail are mutually coupled by virtue of a ball retainer, so that the middle rail can linearly displace relative to the outer rail along the axis direction, and meanwhile, the inner rail can linearly slide relative to the middle rail along the axis direction.
The Chinese invention with the bulletin number of 205052031U discloses a sliding rail structure, which is characterized in that an inner frame front lock is axially connected with an inner rail, one end of the inner frame front lock is hinged on the inner rail, the other end of the inner frame front lock is a sliding block arranged in a first sliding groove of the inner rail, the lower edge of the inner frame front lock is provided with a locking notch, one side of the locking notch is a bevel edge, the other side of the locking notch is a vertical edge, an arc chamfer is arranged between the locking notch and the bevel edge, a spring is connected between the inner frame front lock and the inner rail, the inner frame front lock plays a role of limiting excessive opening of the inner rail, however, the spring is a bent metal strip, two ends of the spring are bent into connectors, one end of the connector is clamped in a connecting hole of the inner rail, and the other end of the connector is clamped in a connecting hole of the inner frame front lock, so that the sliding rail has some problems: although the occupied volume is smaller, the inner frame front lock still occupies a certain volume, and the inner frame front lock needs to be bent for a certain angle to avoid the spring as seen in the attached drawing of the specification, and meanwhile, the inner frame front lock can only be processed to a thinner thickness, so that the inner frame front lock is easy to deform and has poor reliability; in addition, the spring that it adopted actually is a both ends and bend into the crooked metal strip of connector, and the connector is established in the connecting hole of lock before interior rail and inside casing respectively card, however when interior rail and well rail take place the relative slip, the connector of spring is deviate from the connecting hole easily, causes the spring inefficacy, and the reliability of slide rail locking is relatively poor.
In addition, the sliding block and the first sliding groove are not in a limiting relation in the transverse direction, so that when the inner rail and the middle rail slide relatively, the front lock of the inner frame swings, one end, provided with the sliding block, of the front lock of the inner frame is easy to tilt, the sliding block is easy to separate from the first sliding groove, the front lock of the inner frame is invalid, and the reliability of the sliding rail is poor.
