Description

Technical Field

[0001] The present application relates to the field of communication equipment, and in particular to a retractable handle. Background Art

[0002] The development trend of airborne communication equipment is mainly digitization (implementing digital communication centered on airborne electronic computers) and integration (integrating single-function radio stations into multi-function radio stations, thereby combining aircraft radio stations with other airborne electronic equipment to form a multi-function integrated electronic system), further reducing the size, weight and power consumption of airborne communication equipment, and improving its reliability, confidentiality and anti-interference capabilities.

[0003] Airborne equipment often has limited installation space, and miniaturization of communication equipment has become a new trend. It is particularly important that airborne equipment is easy to install and operate in a small space. Protrusions on the panel of communication equipment, such as handles, sometimes affect the operation and installation of the equipment.

[0004] At present, the handles on communication equipment are mostly fixed on the panel, with large protrusions and large space occupation. When the panel area is limited and the connector layout is compact, the handle may affect the connection of the connector cable on the equipment panel and even affect the tightening of the equipment installation screws. Summary of the invention

[0005] To achieve the above-mentioned purpose and other related purposes, the present application discloses a retractable handle, including a handle, the handle is inserted into the device panel and is slidingly connected to the device panel, and also includes a bolt, a nut and a compression spring. The bolt passes through the handle and the device panel, and the nut is threadedly connected to one end of the bolt passing through the device panel. The interior of the connection between the handle and the bolt is hollow, and the compression spring is sleeved on the part of the bolt located on the handle, and one end of the compression spring is fixedly connected to the inside of the handle, and the other end of the compression spring abuts against the nut of the bolt.

[0006] Furthermore, a guide sleeve is provided between the compression spring and the bolt, the guide sleeve is threadedly connected to the bolt, the compression spring and the guide sleeve are slidingly connected, a limiting ring is fixedly provided at the end of the guide sleeve close to the nut, and the limiting ring is fixedly connected to one end of the compression spring close to the nut.

[0007] Furthermore, a small washer is provided between the nut of the bolt and the limiting ring.

[0008] Furthermore, a spring washer is provided between the nut of the bolt and the limiting ring.

[0009] Furthermore, a blocking piece is detachably connected to the surface of the device panel, and a protruding structure is fixedly provided on the part of the handle located inside the device panel. When the handle is pulled in a direction away from the device panel to a preset distance, the blocking piece is engaged with the protruding structure.

[0010] By adopting the above technical solution, when in a normal state, the compression spring is in a normal state, and the handle is located inside the device panel under the elastic force of the compression spring. When the handle is pulled, the handle moves in a direction away from the surface of the device panel, and the compression spring is compressed. After use, the elastic force of the compression spring causes the handle to automatically return to its original position, and the handle is placed. In a normal state, the handle does not occupy a position, so as to reduce the occupied space and the protrusion, and facilitate the plugging and unplugging of the panel connector and the tightening of the device mounting screws.

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0015] Reference Figure 1 and Figure 2 The embodiment of the present application provides a retractable handle, in which the handle 1 is inserted into the device panel 10 and is slidably connected to the device panel 10, and the direction of the sliding connection of the handle 1 is perpendicular to the surface of the device panel 10. The device panel 10 is provided with a cavity for placing the two ends of the handle 1, and the two ends of the handle 1 are inserted into the cavity.

[0016] Bolts 2, nuts 3 and compression springs 4 are provided at both ends of the handle 1, and a cavity is provided inside the handle 1 for placing the bolts 2 and compression springs 4. The bolt 2 passes through the handle 1 and the device panel 10, and the nut 3 is threadedly connected to one end of the bolt 2 passing through the device panel 10, and the nut 3 abuts against the device panel 10.

[0017] Reference Figure 3 and Figure 4 , a guide sleeve 5 is sleeved on the side of the bolt 2, the guide sleeve 5 is threadedly connected to the bolt 2, a compression spring 4 is sleeved on the outside of the guide sleeve 5, one end of the compression spring 4 is fixedly connected to the part of the handle 1 near the nut 3; a limit ring 51 is fixedly provided at one end of the guide sleeve 5 near the nut, and the other end of the compression spring 4 is fixedly connected to the guide sleeve 5. When in a normal state, the compression spring 4 is in a normal state, at which time the handle 1 is subjected to the elastic force of the compression spring 4 and is located inside the device panel 10. When the handle 1 is pulled, the handle 1 moves in a direction away from the surface of the device panel 10, and the compression spring 4 is compressed. After use, the elastic force of the compression spring 4 causes the handle 1 to automatically return to its original position and complete the placement, so as to reduce the occupied space, reduce the protrusion, and facilitate the plugging and unplugging of the panel connector and the tightening of the device mounting screws.

[0018] A small washer 6 and a spring washer 7 are provided between the limiting ring 51 and the bolt 2 to protect the limiting ring 51 and the bolt 2 .

[0019] The surface of the device panel 10 is detachably connected with a baffle 8, which is connected to the device panel 10 via a bolt 2. The portion of the handle 1 located inside the device panel 10 is fixedly provided with a protruding structure 9. When the handle 1 is pulled away from the device panel 10 to a preset distance, the baffle 8 is engaged with the protruding structure 9. When the handle 1 is pulled out to a certain length, the protruding structure 9 of the handle 1 can be limited by the baffle 8. At this time, the handle 1 cannot be further extended, which well protects the compression spring 4 and prolongs its service life.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
