Description

Technical Field

[0001] The invention belongs to the technical field of airborne electronic equipment structure design, and in particular relates to a novel guide screw type positioning pin. Background Art

[0002] When the storage disk of a certain type of airborne recording equipment was being designed and demonstrated on the equipment, it was found that the current fixing structure of the storage disk only had positioning pins but no guide pins. The positioning pins could not guide the storage disk, which could easily cause the storage disk to be inserted crookedly and slanted, thereby causing damage to the connector. In addition, due to the small installation space, ordinary positioning pins could not be installed. At the same time, the machining tolerance of the cone surface of the commonly used 28° conical positioning pin would cause a large displacement of the front and rear position of the module, so the positioning pins of the storage disk needed to be optimized. Summary of the invention

[0003] In view of this, the present invention provides a novel guide screw type positioning pin, which realizes the guiding, positioning and precise installation of airborne electronic equipment and its modules during installation, and can solve the problem of installing the positioning pin when the space is narrow.

[0004] The technical solution of the present invention is:

[0005] A novel guide screw type positioning pin is used for guiding installation when installing a module on an airborne electronic device. The positioning pin comprises:

[0006] head;

[0007] A threaded portion, connected to one end of the head, provided with an external thread;

[0008] A positioning portion, coaxially connected to an end of the threaded portion away from the head, and provided with a positioning inclined surface;

[0009] A guide portion, coaxially connected to an end of the positioning portion away from the threaded portion;

[0010] Wherein: when the module is installed inside the device based on the positioning pin guide, a positioning sleeve is provided on the module, the guiding part is sleeved in the positioning sleeve, and the positioning part acts on the end opening of the positioning sleeve.

[0011] Furthermore, the outer ring of the positioning portion is a conical slope.

[0012] Furthermore, the conical slope is a 45° slope.

[0013] Further, the positioning pin is connected to the device based on the threaded portion.

[0014] Furthermore, a gap is set between the device and the module.

[0015] Furthermore, the diameter of the guide portion is smaller than the inner diameter of the positioning sleeve.

[0016] The beneficial effects of the present invention are:

[0017] The present invention proposes a novel guide screw type locating pin structure, which realizes the guiding, positioning, precise installation of airborne electronic equipment and its modules during installation, and the installation of locating pins when the space is narrow, thereby solving the problems that ordinary guide pins cannot be positioned, ordinary locating pins cannot be guided, locating pins cannot be installed when the space is narrow, and the problem that airborne electronic equipment and its modules cannot be precisely installed.
