Description

Technical Field

[0001] The present application relates to the field of communication equipment, and in particular to a foldable 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 foldable handle, including a base, a handle and a double-link mechanism, wherein two bases are provided and the bases are provided on the device panel, the two bases are provided at both ends of the handle, and each base is connected to one end of the handle through a double-link mechanism.

[0006] Furthermore, a positioning pin is fixedly provided at a portion of the handle close to the device panel, and a positioning hole for clamping the positioning pin is provided at a position of the base corresponding to the positioning pin.

[0007] Furthermore, a rubber plug is inserted into the positioning hole, and a positioning pin is inserted into the rubber plug.

[0008] Furthermore, two double-link mechanisms are provided at each base, and the double-link mechanisms are respectively located above and below the end of the handle, one end of the double-link mechanism is connected to the end of the handle through a rivet, the handle and the rivet are rotationally connected, the double-link mechanism and the rivet are rotationally connected, and the other end of the double-link mechanism is connected to the base through a rivet, and the base and the rivet are rotationally connected.

[0009] By adopting the above technical solution, when the handle is not needed, the handle can be folded through the double-link mechanism to reduce the occupied space and the protrusion, which is convenient for plugging and unplugging the panel connector and tightening the equipment installation screws.

[0013] 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.

[0014] Reference Figure 1 and Figure 2 The embodiment of the present application provides a foldable handle, including a base 1, a handle 2 and a double-link mechanism 3, wherein two bases 1 are provided and the bases 1 are provided on the device panel, and the bases 1 are connected to the device panel by bolts; two bases 1 are provided at both ends of the handle 2, and each base 1 is connected to one end of the handle 2 by a double-link mechanism 3, wherein two double-link mechanisms 3 are provided at each base 1, and the double-link mechanisms 3 are respectively located above the end of the handle 2 and below the end of the handle 2, one end of the double-link mechanism 3 is connected to the end of the handle 2 by a rivet, the handle 2 is rotationally connected to the rivet, the double-link mechanism 3 is rotationally connected to the rivet, and the other end of the double-link mechanism 3 is connected to the base 1 by a rivet, and the base 1 is rotationally connected to the rivet. Among them, the two connecting rods in the double-link mechanism 3 are also connected by rivets, and the rivets are both rotationally connected to the connecting rods, and the pan heads of the rivets are installed on the side of the connecting rod away from the surface of the handle 2.

[0015] Reference Figure 3 , Figure 4 and Figure 5 A locating pin 4 is fixedly provided at the part of the handle 2 close to the device panel. A locating hole for clamping the locating pin 4 is opened at the position of the base 1 corresponding to the locating pin 4. A rubber plug 5 is inserted into the locating hole. The rubber plug 5 has an opening. The outer diameter of the rubber plug 5 is slightly larger than the diameter of the locating hole. The rubber plug 5 is fixed by interference fit.

[0016] As mentioned above, when the handle 2 is needed, the double link mechanism 3 is straightened. When the handle 2 is used, the double folding mechanism is folded along the push handle 2 close to the surface of the device panel, and the positioning pin 4 is inserted into the rubber plug 5. The friction of the rubber plug 5 forms a limit for the positioning pin 4, reducing the situation where the positioning pin 4 is separated from the positioning hole. At this time, when the connector needs to be operated, or a screwdriver is used to operate other parts on the device panel, the handle 2 will not affect the operation. The handle 2 is folded by the double link mechanism 3 to reduce the occupied space and the protrusion, which is convenient for the panel connector to be plugged in and out and the tightening of the device installation screws. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it; although the present application is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
