Abstract

This invention relates to a positioning device structure, which includes a fixing device disposed on a plate. The fixing device includes a positioning base, a positioning member, and a sleeve. The positioning base has an extension and a fixing groove. The positioning member passes through the extension and the sleeve is sleeved on the outside. After assembly, the fixing protrusion inside the sleeve impacts the surface of the base and deforms to be tightly embedded into the fixing groove by stamping, forming a stable connection. This ensures that the sleeve does not make recessed contact with the surface of the plate during the stamping deformation process. Furthermore, the plate is provided with limiting protrusions to form a buffer space to prevent damage to the coating. This provides a positioning assembly solution with high stability and no damage to the appearance coating.

Claims

1. A positioning device structure, comprising a fixing device disposed on a plate, wherein: The plate is provided with assembly holes for assembling the fixing device; the fixing device includes a positioning base, a positioning member and a sleeve. The base of the positioning base extends to the top of the plate through the assembly hole, and the extension has a longitudinally penetrating receiving space. A fixing groove is recessed inward between the base and the extension. The positioning member has a rod extending downward to a fixing head that passes through the receiving space. A cover is provided at the top of the rod. The sleeve is fitted around the positioning base and forms an internal storage space. An inner wall is provided around the side of the sleeve facing the positioning base. The inner wall of the sleeve is formed by pressing the upper and lower parts of the sleeve through a preset process and impacting the surface of the base to form a fixing protrusion that is fixed in the fixing groove.

2. The positioning device structure as described in claim 1, wherein a protruding limiting protrusion is provided around the assembly hole of the plate, thereby forming a reserved distance between the protrusion and the plate, and a positioning plate is formed at the periphery of the assembly hole adjacent to the limiting protrusion, and a positioning surface is provided at the periphery of the base of the fixing device, which supports the positioning plate below.

3. The positioning device structure as described in claim 1, wherein a limiting protrusion is provided on the wall near the lower part of the receiving space of the extension of the fixing device, located above the fixing head.

4. The positioning device structure as described in claim 1, wherein the accommodating space of the fixing device is provided with a stepped abutment section with the upper inner diameter being larger than the lower inner diameter, and an elastic member is further sleeved on the rod of the positioning member of the fixing device, wherein the top of the elastic member abuts against the bottom surface of the cover of the positioning member, and the bottom of the elastic member abuts against the surface of the abutment section in the positioning seat.

5. The positioning device structure as described in claim 1, wherein the top of the cover surface of the rod of the fixing device is provided with an engaging portion having an engaging groove.

6. The positioning device structure as described in claim 2, wherein the diameter of the positioning surface of the base of the fixing device is larger than the diameter of the assembly hole, and the diameter of the assembly hole is larger than the diameter of the extension.

7. The positioning device structure as described in claim 1, wherein the sleeve of the fixing device is made of a soft metal material with good plasticity.
