Description

Technical Field

[0001] The utility model relates to the technical field of spiral locking nails, in particular to a spiral locking nail. Background Art

[0002] At present, a spiral locking nail is often used in the panel structure of airborne electronic equipment in the fields of aviation, aerospace, etc.

[0003] The utility model patent application document with the publication number "CN206608412U" discloses a 90° spiral quick-release locking device, which is mainly composed of a spiral lock pin, a spring and a bushing. The technical solution is to insert a flat screwdriver into the flat groove of the spiral lock pin, apply pressure along the axis of the spiral lock pin and rotate the screwdriver clockwise, so that the spiral surface of the spiral lock pin slides along the surface of the steel wire in the lock seat until it rotates 90° to reach the stop position, and the spring is in a compressed state, so that the spiral lock pin cannot be automatically disengaged from the steel wire of the lock seat, and the locking is completed. When unlocking, the quick-release locks around the instrument panel are opened respectively. Unlocking is to rotate the spiral lock pin 90° counterclockwise with a screwdriver. The lock pin overcomes the elastic force of the spring, slides out along the spiral surface and disengages from the steel wire. After all the quick-release locks are opened, the instrument panel can be opened.

[0004] The spiral quick-release locking device disclosed in the above document has the following defects: the connection between the sleeve and the instrument panel of the spiral quick-release locking device may be deformed during long-term use, causing the sleeve to be detached from the mounting hole of the instrument panel and lose its use effect.

[0005] It can be seen from this that the bushing of the existing spiral quick-release locking device does not have a good fixing structure, and it is necessary to improve the existing shortcomings and provide a spiral locking nail. Utility Model Content

[0006] The purpose of the utility model is to provide a spiral locking nail to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses a spiral locking nail, comprising a spiral locking nail, a first spring and a bushing, wherein a through hole is formed on the outer surface of the bushing, a fixing structure is arranged inside the through hole, the fixing structure comprises a connecting plate, a supporting plate, an abutting plate, a sleeve, a threaded rod, a disc body, a turning handle and a suction cup, a supporting plate is arranged at one end of the connecting plate, an abutting plate is arranged on the lower surface of the supporting plate, a sleeve is arranged at the middle part of the connecting plate, a threaded rod is connected to the inner thread of the sleeve, a disc body is installed at one end of the threaded rod, a suction cup is installed at the other end of the threaded rod, a turning handle is arranged at one end of the disc body away from the threaded rod, and the connecting plate is installed inside the through hole.

[0009] Furthermore, the lower surface of the abutment plate is provided with anti-slip stripes.

[0010] Furthermore, a spiral lock pin is installed inside the bushing, one end of the spiral lock pin passes through the bushing and extends downward, a first spring is sleeved on the outer surface of the spiral lock pin, and a straight groove is provided on the upper surface of the spiral lock pin.

[0011] Furthermore, a cavity is provided inside the connecting plate, through openings are provided at both ends of the connecting plate, one end of the through opening extends to the inside of the cavity, and a quick-release assembly is provided inside the cavity.

[0012] Furthermore, the quick-release assembly includes a limit block, a slider and a second spring. The slider is slidably connected inside the cavity. The slider is fixed in two and symmetrically arranged. A second spring is installed between the two sliders. A limit block is installed on one end of the slider away from the second spring. The limit block is slidably connected inside the through opening, and the outer surface of the limit block abuts against the inner surface of the bushing.

[0013] Furthermore, an outer surface of the limit block is provided with an inclined surface.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model can increase the tightness between the bushing and the instrument panel by setting a fixing structure, so that the bushing is not easy to separate from the instrument panel during long-term use, which has a good fixing effect and prolongs the service life of the bushing.

[0016] (2) The utility model squeezes the limit block so that the limit block pushes the slider to move inside the cavity, and at the same time the second spring gradually contracts. When the limit block is flush with the outer surface of the connecting plate, the connecting plate is pulled outward so that the connecting plate is detached from the inside of the through hole, completing the separation of the fixed structure and the bushing. Then, the bushing or the fixed structure can be replaced, saving material loss and achieving a better environmental protection effect.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
