Description

Technical Field

[0001] The invention relates to a front-mounted quick-installation structure that eliminates cable installation stress. Background Art

[0002] At present, the installation methods of the components (such as switches, sensors, etc.) on the aircraft control panel are relatively complicated. It is necessary to disassemble the installation structure of the device, install one part from the front of the installation panel, and install the other part from the back of the installation panel, and then combine them. This operation cannot meet the requirements of maintenance accessibility. In addition, after installation, the rear cable (wire or cable) of the installed component generates torque due to rotation during the process, which generates installation stress. Summary of the invention

[0003] The primary technical problem that the present invention solves is the complex panel installation operation and poor accessibility. A further technical problem that the present invention solves is the torque generated on the rear end wires or cables of the installed component after installation. A further technical problem that the present invention solves is to achieve panel sealing, thereby providing a new front-mounted quick installation structure that eliminates cable installation stress.

[0004] In order to achieve this purpose, the technical solution of the present invention is as follows: a front-mounted quick installation structure for eliminating cable installation stress, comprising:

[0005] An installation panel is formed with a square installation hole having a square structure and extending downward from the top surface of the installation panel to the bottom surface of the installation panel;

[0006] The mounting sleeve comprises an upper sleeve portion and a lower sleeve portion, wherein the upper sleeve portion is placed above the mounting panel and the bottom surface of the upper sleeve portion is in surface contact with the top surface of the mounting panel, a limited step is formed on the inner circumference of the upper sleeve portion, and a limited riveting edge is also formed on the upper sleeve portion, and the lower sleeve portion extends downward from the bottom surface of the upper sleeve portion;

[0007] The installation gasket comprises an upper gasket portion and a lower gasket portion, wherein the lower gasket portion is placed below the installation panel, the lower gasket portion is a square structure corresponding to the installation square hole, the lower gasket portion is coaxial with the installation square hole and is horizontally cross-arranged at 45 degrees, the top surface of the lower gasket portion is in surface contact with the bottom surface of the installation panel, the upper gasket portion extends upward from the top surface of the lower gasket portion to the inside of the installation square hole, the upper gasket portion is enclosed by four identical upper side walls connected end to end, and the upper side wall has a broken line segment, a tangent segment, and a transition connecting the broken line segment and the tangent segment. The four fold line segments are respectively in surface contact with the four inner surfaces of the installation square hole, and the four tangent segments are respectively overlapped with the four outer surfaces of the lower part of the gasket in the vertical direction, so that when the installation gasket is horizontally rotated 45°, the four tangent segments can respectively be in surface contact with the four inner surfaces of the installation square hole; the installation gasket has a gasket through hole that starts from the top surface of the upper part of the gasket and penetrates downward to the bottom surface of the lower part of the gasket, and the lower part of the sleeve extends downward to the inside of the gasket through hole and is threadedly matched with it, so that the installation sleeve is fixedly combined with the installation gasket; and,

[0008] The mounted part is placed inside the mounting sleeve, and a limiting protrusion is formed on the outer circumferential surface of the mounted part. The bottom surface of the limiting protrusion is in surface contact with the top surface of the limiting step, and the top surface of the limiting protrusion is in surface contact with the bottom surface of the limiting rivet edge, so that the mounted part is limited vertically but not circumferentially.

[0009] As a preferred solution for a front-mounted quick installation structure that eliminates cable installation stress, a sleeve bottom groove is formed on the bottom surface of the upper portion of the sleeve, and the sleeve bottom groove and the installation gasket together define an annular space, and a silicone rubber filler is provided in the annular space.

[0010] As a preferred solution of a front-mounted quick installation structure for eliminating cable installation stress, the transition section is an arc.

[0011] As a preferred solution for a front-mounted quick installation structure that eliminates cable installation stress, the lower portion of the sleeve is a cylindrical structure, an external thread is formed on the outer circumferential surface of the lower portion of the sleeve, and an internal thread corresponding to the external thread is formed on the inner circumferential surface of the gasket through hole. The external thread cooperates with the internal thread to achieve threaded cooperation between the lower portion of the sleeve and the gasket through hole.

[0012] As a preferred solution of a front-mounted quick installation structure for eliminating cable installation stress, the installed component is a sensor or a switch.

[0013] Compared with the prior art, the beneficial effects of the present invention are at least as follows: (1) the overall installation structure is simple and easy to process, and can be quickly disassembled and easily maintained; (2) the installation sleeve and the installation gasket can be directly installed through the installation square hole without disassembly; (3) the installed component can generate relative circumferential rotational motion with the installation sleeve, eliminating the torque generated on the rear end cable of the installed component during the installation process; and (4) the silicone rubber filler can be used to achieve sealing between the installation sleeve and the installation panel.

[0023] The present invention is further described in detail below by means of specific embodiments in combination with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] See also Figures 1 to 4The figure shows a front-mounted quick installation structure for eliminating cable installation stress. The front-mounted quick installation structure is mainly composed of a mounting panel 1, a mounting gasket 2, a mounting sleeve 3, a mounted part 4 and a silicone rubber filler 5.

[0025] The installation panel 1 is provided with a square installation hole 10 extending from the top surface of the installation panel 1 downward to the bottom surface of the installation panel 1. The inner circumference of the installation square hole 10 has four square hole side surfaces. Furthermore, two adjacent square hole side surfaces are smoothly transitioned with rounded corners.

[0026] See also Figure 5 The mounting sleeve 3 has a sleeve upper portion 31 and a sleeve lower portion 32. The sleeve upper portion 31 is a hexagonal head. The sleeve upper portion 31 is placed above the mounting panel 1. The outer diameter of the sleeve upper portion 31 is greater than the side length of the mounting square hole 10. The bottom surface of the sleeve upper portion 31 is in surface contact with the top surface of the mounting panel 1 to prevent the mounting sleeve 3 from falling into the mounting square hole 10. A limiting step 311 is formed on the inner circumferential surface of the sleeve upper portion 31, and the limiting step 311 extends inward. The sleeve upper portion 31 also forms a limiting riveting edge 310. The number of the limiting riveting edges 310 is 3-8 petals. The sleeve lower portion 32 extends downward from the bottom surface of the sleeve upper portion 31. The sleeve lower portion 32 is a circular cylinder. An external thread is formed on the outer circumferential surface of the sleeve lower portion 32.

[0027] See also Figure 7 and 8The mounting gasket 2 has a gasket upper part 21 and a gasket lower part 22. The gasket lower part 22 is placed below the mounting panel 1. The gasket lower part 22 is a square structure corresponding to the mounting square hole 10, so that during the front installation process, the gasket lower part 22 can enter the bottom of the mounting panel 1 from the top of the mounting panel 1, just passing through the mounting square hole 10. After entering the mounting panel 1, the gasket lower part 22 is coaxial with the mounting square hole 10 and horizontally cross-arranged at 45° (when the mounting gasket 2 is horizontally rotated 45°, the gasket lower part 22 can overlap with the mounting square hole 10 in the vertical direction), and the top surface of the gasket lower part 22 is in surface contact with the bottom surface of the mounting panel 1 to prevent the mounting gasket 2 from being pulled out upward. The gasket upper part 21 extends upward from the top surface of the gasket lower part 22 to the inside of the mounting square hole 10. The gasket upper portion 21 is confined within the area defined by the outer circumference of the gasket lower portion 22. The gasket upper portion 21 is formed by four identical upper side walls connected end to end and enclosed, and the upper side walls have a fold line segment 213, a tangent segment 212, and a transition segment 211 (circular arc) connecting the fold line segment 213 and the tangent segment 212. The four fold line segments are in surface contact with the four inner surfaces of the installation square hole 10, respectively, and the four tangent segments are overlapped with the four outer surfaces of the gasket lower portion 22 in the vertical direction, respectively, so that when the installation gasket 2 is horizontally rotated 45°, the four tangent segments can be in surface contact with the four inner surfaces of the installation square hole 10, respectively.

[0028] The mounting gasket 2 has a gasket through hole extending downward from the top surface of the gasket upper portion 21 to the bottom surface of the gasket lower portion 22. The sleeve lower portion 32 extends downward to the interior of the gasket through hole and is threadedly engaged with the gasket, so that the mounting sleeve 3 is fixedly combined with the mounting gasket 2. In this embodiment, the sleeve lower portion 32 is a cylindrical structure, an external thread is formed on the outer circumferential surface of the sleeve lower portion 32, and an internal thread corresponding to the external thread is formed on the inner circumferential surface of the gasket through hole. The threaded engagement of the sleeve lower portion 32 and the gasket through hole is achieved by the engagement of the external thread and the internal thread.

[0029] The mounted component 4 may be a sensor or a switch. Figure 4 The mounted part 4 is placed inside the mounting sleeve 3. A limiting protrusion 40 is formed on the outer circumference of the mounted part 4, and the limiting protrusion 40 extends outward. The bottom surface of the limiting protrusion 40 is in surface contact with the top surface of the limiting step. Figure 6The top surface of the limiting protrusion 40 is in surface contact with the bottom surface of the limiting riveted edge 310, so that the installed component 4 is vertically limited but not circumferentially limited. After installation, the installed component can generate relative circumferential rotational motion with the installation sleeve 3, eliminating the torque generated on the rear cable of the installed component during the installation process.

[0030] A sleeve bottom groove is formed on the bottom surface of the sleeve upper part 31. The sleeve bottom groove and the mounting gasket 2 define an annular space together. A silicone rubber filler 5 is provided in the annular space. The silicone rubber filler 5 can be used to achieve sealing between the mounting sleeve 3 and the mounting panel 1.

[0031] Installation method: Provide the installation panel 1, the installation sleeve 3, the installation gasket 2, the installed part 4 and the silicone rubber filler 5. Assemble the installation sleeve 3 and the installation gasket 2 to form an integral component. Align the installation gasket 2 with the installation square hole 10 of the installation panel 1 (at this time, the four tangent segments of the upper part 21 of the gasket correspond to the installation square hole 10 respectively). The lower part 22 of the gasket passes through the installation square hole 10 from above the installation square hole 10 downward until the top surface of the lower part 22 of the gasket is flush with the bottom surface of the installation panel 1. Rotate the installation gasket 2 clockwise, and after rotating 45°, the four folded line segments of the upper part 21 of the gasket correspond to the installation square hole 10 respectively. Use the upper part 31 of the sleeve to position the overall component upward. Use the lower part 22 of the gasket to position the overall component downward. Complete the installation of the overall component. Finally, the installed component 4 is installed, and the limiting riveting edge 310 is used to limit the position.

[0032] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
