Description

Technical Field

[0001] This invention relates to the field of handle technology, and in particular to a tool-free, quick-release handle for avionics enclosures and its usage method. Background Technology

[0002] The chassis handle is designed for lifting and placing the chassis during transport. See [link / reference]. Figure 1 As shown, the handle 1 of a traditional avionics chassis is directly fixed to the chassis with two screws. Disassembly and assembly require tools such as screwdrivers, making quick assembly and disassembly impossible. The handle diameter is 8mm. Considering the damp heat, salt spray, and mold testing conditions and load-bearing capacity, the handle material is generally 1Cr18Ni9 stainless steel. A single handle weighs over 100g, and the handle is not removed when the chassis is installed, which is detrimental to the overall weight reduction and lightweighting of the avionics chassis. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a tool-free, quick-release handle for avionics chassis. This handle enables tool-free quick installation when lifting and placing the chassis, and tool-free quick disassembly when not lifting or placing the chassis, thereby achieving overall lightweight design of the chassis.

[0004] The first objective of this invention is to provide a tool-free, quick-release handle for an avionics enclosure, comprising a handle component and handle housings disposed at both ends of the handle component;

[0005] Each handle housing is detachably connected to the front panel of the chassis via a connecting mechanism;

[0006] Each connection mechanism includes:

[0007] The connector has one end that passes through the front panel of the chassis and is hooked to the inside of the front panel of the chassis, and the other end that passes through the handle housing and extends to the outside of the handle housing to form a free end;

[0008] A spring is fitted onto the connector and located within the handle housing.

[0009] A square handle is fitted onto the free end and is tightly attached to the handle housing by a nut screwed onto the free end.

[0010] Preferably, each connector includes a threaded end cap b, a hook rod, and a double-ended sleeve rod;

[0011] One end of the hook rod passes through the front panel of the chassis and is connected to a crossbar. The crossbar is close to the inner side of the front panel of the chassis. The other end of the hook rod passes through the threaded end cap b and is inserted into the handle housing and connected to one end of the double-headed sleeve rod. The spring is sleeved on the hook rod between the threaded end cap b and the double-headed sleeve rod. The crossbar is perpendicular to the axis of the hook rod.

[0012] The other end of the double-ended lever extends out of the handle housing to form the free end.

[0013] Preferably, the inner diameter of the threaded end cap b is provided with threads, and the outer diameter of the handle housing is provided with threads. After the threads on the threaded end cap b and the handle housing are screwed into place, the other end of the double-ended sleeve extends to the outside of the handle housing to form the free end.

[0014] Preferably, the end of the hook rod connected to the double-ended sleeve rod is provided as a square end, and the double-ended sleeve rod has a square hole for insertion into the square end;

[0015] The double-ended sleeve rod is riveted at the junction of the square end and the square hole by a horizontally penetrating rivet;

[0016] The double-headed sleeve rod is provided with a first light hole for the rivet to pass through;

[0017] The square end has a second light hole for the rivet to pass through.

[0018] Preferably, the diameter of the first section of the double-ended sleeve located inside the handle housing is greater than the diameter of the second section located outside the handle housing;

[0019] The handle housing has a through hole for the second section to pass through.

[0020] Preferably, the square handle has a first waist-shaped hole at its center, and the free end has a screw end containing two symmetrical planes for passing through the first waist-shaped hole.

[0021] Preferably, the front panel of the chassis has a second oblong hole through which the end of the hook rod and the connected crossbar pass. In use, the end of the hook rod and the connected crossbar are passed through the second oblong hole, and the crossbar is hooked onto the inside of the front panel of the chassis by rotating the hook rod.

[0022] Preferably, each of the handle housings has a specific cylindrical structure.

[0023] The second objective of this invention is to provide a chassis equipped with the aforementioned tool-free, quick-release avionics chassis handle.

[0024] The third objective of this invention is to provide a method for quickly assembling and disassembling avionics chassis handles without tools, comprising the following steps:

[0025] Align the crossbar connected to the end of the hook with the first oblong hole inserted into the front panel of the chassis. Press the square handle firmly. The square handle will move the crossbar on the hook towards the inside of the front panel of the chassis. When the moving distance exceeds the thickness of the crossbar, rotate the square handle 90 degrees. The square handle will then rotate the crossbar on the hook 90 degrees. Release the square handle.

[0026] Under the force of the spring, the crossbar on the hook will move outward to the front panel of the chassis, and the handle component will be fixedly connected to the avionics chassis on one side.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] This invention provides a tool-free, quick-release avionics chassis handle and its usage method. First, it allows the product to be installed without the handle, which is beneficial for overall weight reduction and lightweighting. Second, it enables quick installation, connection, and disassembly of the handle and avionics chassis, resulting in high operational efficiency. Third, the quick installation, connection, and disassembly of the handle and avionics chassis can be performed by hand without the need for any tools, making it convenient to operate.

[0039] The following describes several specific embodiments of the present invention in detail, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0040] The first aspect of this invention provides a tool-free, quick-release handle for an avionics chassis, see [link / reference]. Figures 2-10 As shown, it includes a handle component 3 and handle housings 7 disposed at both ends of the handle component 3;

[0041] Each handle housing 7 is detachably connected to the front panel 4 of the chassis via a connecting mechanism;

[0042] Each connecting mechanism includes a connector and a square handle 10; one end of the connector passes through the front panel 4 of the chassis and is hooked to the inside of the front panel 4 of the chassis, and the other end passes through the handle housing 7 and extends to the outside of the handle housing 7 to form a free end; a spring 12 is sleeved on the part of the connector located inside the handle housing 7; the square handle 10 is sleeved on the free end and is tightly attached to the handle housing 7 by a nut 11 screwed to the free end.

[0043] This invention uses a connecting mechanism to detachably connect the handle housing to the front panel of the chassis, enabling the handle to be installed during use and removed when not in use. In normal assembly, the product can be handle-less, achieving overall weight reduction and lightweighting. It allows for quick installation, connection, and disassembly of the handle and avionics chassis, resulting in high operational efficiency.

[0044] Specifically, each connector includes a threaded end cap b6, a hook rod 13, and a double-ended sleeve rod 9;

[0045] One end of the hook rod 13 passes through the front panel 4 of the chassis and is connected to a crossbar 14. The crossbar 14 is close to the inside of the front panel 4 of the chassis. The other end of the hook rod 13 passes through the threaded end cap b6 and is inserted into the handle housing 7, connecting to one end of the double-ended sleeve rod 9. A spring 12 is fitted between the threaded end cap b6 and the double-ended sleeve rod 9. The crossbar 14 is perpendicular to the axis of the hook rod 13. The other end of the double-ended sleeve rod 9 extends to the outside of the handle housing 7 to form a free end. Therefore, the hook head formed by the crossbar 14 connected to the end of the hook rod 13 is used to hook the inside of the front panel 4 of the chassis, thereby fixing the handle component to the chassis panel.

[0046] By providing a second oblong hole 20 for the end of the hook rod 13 and the connected crossbar 14 to pass through in the front panel 4 of the chassis, when in use, the end of the hook rod 13 and the connected crossbar 14 are passed through the second oblong hole 20, and the crossbar 14 is hooked onto the inside of the front panel 4 of the chassis by rotating the hook rod 13.

[0047] Specifically, the threaded end cap b6 has threads on its inner diameter, and the handle housing 7 has threads on its outer diameter. After the threads on the threaded end cap b6 and the handle housing 7 are screwed into place, the other end of the double-ended sleeve 9 extends out of the handle housing 7 to form a free end. It should be noted that one end of the spring 12 is connected to the threaded end cap b6, and the other end is connected to the connection between the hook rod 13 and the double-ended sleeve 9; thus, under the action of the spring, the hook rod 13 is pushed to move outward of the chassis.

[0048] One end of the hook rod 13 connected to the double-ended sleeve rod 9 is designated as a square end 16. The double-ended sleeve rod 9 has a square hole 17 for insertion into the square end 16. At the insertion point between the square end 16 and the square hole 17, a transversely penetrating rivet 8 is used for riveting on the double-ended sleeve rod 9. A first clear hole 18 for the rivet 8 to pass through is provided on the double-ended sleeve rod 9. A second clear hole 15 for the rivet 8 to pass through is provided on the square end 16. This achieves a fixed connection between the hook rod 13 and the double-ended sleeve rod 9.

[0049] The diameter of the first section of the double-ended lever 9 located inside the handle housing 7 is larger than the diameter of the second section located outside the handle housing 7; a through hole is provided on the handle housing 7 for the second section to pass through. This facilitates the action of the spring on the hook lever, so that the crossbar 14 at the end of the hook lever is tightly against the inner side of the front panel 14.

[0050] A first oblong hole is provided in the center of the square handle 10, and a screw end 19 containing two symmetrical planes is provided at the free end for passing through the first oblong hole. Therefore, when the first oblong hole on the square handle 10 is fitted onto the screw end 19 containing two symmetrical planes, rotating the square handle 10 can drive the double-headed sleeve 9 to rotate, thus preventing rotation between the square handle and the double-headed sleeve.

[0051] In one embodiment, each handle housing 7 has a specific cylindrical structure.

[0052] A second aspect of the present invention provides a chassis, which is provided with the above-mentioned tool-free avionics chassis handle for quick assembly and disassembly.

[0053] A third aspect of the present invention provides a method for using a tool-free, quick-release avionics chassis handle, comprising the following steps:

[0054] Align the crossbar 14 connected to the end of the hook rod 13 with the first oblong hole 20 on the front panel 4 of the chassis, press the square handle 10 firmly, and the square handle 10 will drive the crossbar 14 on the hook rod 13 to move inward to the front panel 4 of the chassis. When the moving distance exceeds the thickness of the crossbar 14, the square handle 10 can be rotated 90 degrees, and the square handle 10 will drive the crossbar 14 on the hook rod 13 to rotate 90 degrees. Release the square handle 10.

[0055] Under the force of spring 12, the crossbar 14 on hook 13 will move outward to the front panel 4 of the chassis, and the handle component 3 will be fixedly connected to the avionics chassis on one side.

[0056] To illustrate the present invention, the accompanying drawings are provided. Figures 2-9 To further explain, this invention proposes a tool-free, quick-release handle for avionics enclosures.

[0057] The tool-free, quick-assembly and disassembly new handle component 3 consists of a threaded end cap b6, a handle housing 7, a rivet 8, a double-ended sleeve 9, a square handle 10, a nut 11, a spring 12, and a hook 13.

[0058] The tool-free, quick-assembly and disassembly new handle component 3 consists of a threaded end cap b6, a handle housing 7, a rivet 8, a double-ended sleeve 9, a square handle 10, a nut 11, a spring 12, and a hook 13. Except for the handle housing 7, each of the other parts requires two units. The following description only covers one side of the assembly: the hook 13 passes through the threaded end cap b6 and the spring 12 in sequence. The square end 16 on the hook 13 is inserted into the square hole 17 on the double-ended sleeve 9. Then, the rivet 8 passes through the first clear hole 18 on the double-ended sleeve 9 and the second clear hole 15 on the hook 13, and is then riveted. After riveting, the assembly is inserted into the handle housing 7. The inner diameter of the threaded end cap b6 is threaded, and the outer diameter of the handle housing 7 is threaded. After the threads on the threaded end cap b6 and the handle housing 7 are screwed into place, the screw end 19 with two symmetrical planes on the double-ended sleeve 9 will protrude from the handle housing 7. The oblong hole on the square handle 10 is fitted into the screw end 19 on the double-ended sleeve 9. Then, the nut 11 is screwed into the screw end 19 on the double-ended sleeve 9 that protrudes from the square handle 10. This completes the assembly of one side of the tool-free, quick-disassembly and assembly of the new handle component 3.

[0059] The front panel 4 of the chassis has a second oblong hole 20 at the front and a slot 21 on the inside. In order to prevent corrosion of the internal functional circuits of the aviation electronic chassis by salt spray, humid heat and mold, a threaded plug a5 is screwed into the threaded boss 22 on the front panel 4 of the chassis for sealing and isolation.

[0060] When using the tool-free, quick-release handle component 3, align the crossbar 14 on the hook 13 with the second oblong hole 20 on the front panel 4 of the chassis. Press the square handle 10 inwards towards the chassis. The square handle 10 will move the crossbar 14 on the hook 13 inwards towards the chassis. When the movement distance exceeds the thickness of the crossbar 14, rotate the square handle 10 90 degrees. The square handle 10 will then rotate the crossbar 14 on the hook 13 90 degrees. Slowly release the square handle 10. Under the force of the spring 12, the crossbar 14 on the hook 13 will move outwards towards the chassis until it is locked in the slot 21 on the front panel 4. At this point, one side of the tool-free, quick-release handle component 3 is fixedly connected to the avionics chassis. Similarly, after the other side is fixedly connected to the avionics chassis, the tool-free, quick-release handle component 3 and the avionics chassis can be reliably connected. Lifting and lowering the tool-free, quick-release handle component 3 will allow the avionics chassis to be lifted and lowered.

[0061] To disassemble the tool-free, quick-release handle component 3, press the square handle 10 firmly to the left. The square handle 10 will move the crossbar 14 on the hook 13 inwards towards the chassis. When the movement distance exceeds the thickness of the crossbar 14, rotate the square handle 10 90 degrees. The square handle 10 will then rotate the crossbar 14 on the hook 13 90 degrees. Slowly release the square handle 10. Under the force of the spring 12, the crossbar 14 on the hook 13 will move outwards towards the chassis and fall back into the second oblong hole 20 on the front panel 4 of the chassis. At this point, one side of the tool-free, quick-release handle component 3 is disconnected from the avionics chassis. Similarly, after the other side is fixedly connected to the avionics chassis, moving the entire component to the right will completely detach the tool-free, quick-release handle component 3 from the avionics chassis. In normal assembly, this eliminates the need for a handle, achieving overall weight reduction and lightweighting of the product.
