Description

Technical Field

[0001] This utility model relates to the technical field of column locking structures, specifically a locking structure for cabinet columns. Background Technology

[0002] After assembly, servers need to house server and hard drive components. This requires rack rails or slide rails to connect to the uprights on the same side, thus supporting the corresponding server, hard drive, and other cabinet components. Existing rack rails or slide rails require locking structures at both ends of the outer rail or rack rail's length. These existing locking structures, which use elastic protrusions inserted into the corresponding mounting holes on the uprights, are prone to derailment, potentially causing components to fall. Therefore, there is an urgent need to develop a versatile and stable rack upright locking structure. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a locking structure for cabinet uprights, which reliably locks the uprights at the corresponding height position, ensuring good versatility and stable and reliable locking.

[0007] The sliding seat includes a guide base plate and a vertical plate. The vertical plate has protruding positioning protrusions at both ends along its length. The protruding positioning protrusions are shaped to the three sides of the square positioning hole of the corresponding column. The guide base plate has a vertical plate on one side. The guide base plate has a notch and a guide hole. The inner end face of the middle part of the vertical plate along its length is concave to form a bending reinforcement area.

[0008] A fixed base includes a base plate and a vertical plate. The vertical plate has protruding positioning cylinders at both ends along its length. The base plate has a vertical plate on one side and an elastic mechanism mounting protrusion at the end of the base plate away from the vertical plate.

[0009] And flexible mechanisms;

The upright plate of the fixing seat is exposed at the outer end of the base. The guide base plate is pressed onto the front of the base plate. A guide pin seat is provided between the guide base plate and the base. The guide pin seat is positioned opposite the guide hole. The upright plate is located at the inner end of the upright plate. The outwardly protruding positioning protrusion surrounds the outer side of the outwardly protruding positioning cylinder. The elastic mechanism is provided between the inner surface of the bending reinforcement area of ​​the upright plate and the elastic mechanism mounting protrusion.

[0011] Its further features are:

[0012] The base plate is fixed to the front of the base by a pair of small-diameter rivets, and the protruding part of the rivets corresponds to the position of the guide hole.

[0013] The guide hole includes an inner small-diameter waist hole and an outer large-diameter waist hole. The base plate is also fixed to the front of the base by a pair of large-diameter rivets. The upper convex head of the large-diameter rivet is embedded in the outer large-diameter waist hole and presses against the inner small-diameter waist hole, which makes the installation of the upright plate and guide base plate stable and reliable. The large-diameter rivet is the guide pin seat.

[0014] The inner surface of the bending reinforcement area is provided with a positioning protrusion, and the elastic mechanism is a linear spring. The two ends of the linear spring are respectively located opposite the installation protrusion and the positioning protrusion of the elastic mechanism.

[0015] The notch is positioned to correspond to the location of the mounting protrusion of the elastic mechanism, ensuring reliable linear movement of the sliding seat;

[0016] The bending avoidance section includes a bending reinforcement section and a straight arm plate end. The bending reinforcement section improves the elastic strength of the straight arm plate end. The end of the bending reinforcement section passes through the guide notch of the base and connects to the inner end of the straight arm plate end located on the back of the base. The outer end of the straight arm plate end is connected to the locking hook.

[0017] The bending reinforcement section includes an outer bending transition section and an inner reinforcement section, which is a double-layer structure to further ensure elastic strength. The straight arm plate end is provided with at least two parallel reinforcing ribs along the width area.
