Description

Technical Field

[0001] This invention relates to a housing for an electrical device, and more particularly to a quick-release fixing structure that can be quickly locked or opened, and a receiving box having a quick-release fixing structure. Background Technology

[0002] The most common way to secure electrical equipment enclosures is by fastening the top cover to the enclosure with screws. However, using screws requires additional tools for disassembly and assembly, and the process is quite time-consuming. Furthermore, screws are small and easily lost during disassembly and assembly, and repeated disassembly and assembly can easily wear down the screws, causing them to strip.

[0003] Another method of securing the structure involves adding a bridging structure to the shell and a sliding hook structure between the bridging structure and the top cover. Since the hook structure needs to slide laterally to hold the bridging structure in place, a reserved space is required. However, this also means the structure will be somewhat loose after the top cover is closed, and the reserved space will be visible on the exterior.

[0004] Therefore, there is a need for a quick-release fixing structure and a housing with a quick-release fixing structure, which can quickly open and lock the top cover covering the housing, and can avoid gaps between the top cover and the housing caused by the reserved space for the lock head installation. Summary of the Invention

[0005] The main objective of this invention is to provide a quick-release fixing structure and a housing with a quick-release fixing structure, which can quickly open and lock the top cover covering the shell. Furthermore, the design of the quick-release fixing structure of this invention eliminates the gap between the top cover and the shell created to accommodate the pre-installed lock head.

[0006] This invention provides a quick-release fixing structure, disposed on the first side wall of a housing, to fix a top cover to the housing. The top of the housing also has a fastening portion, and the top cover has a protrusion that embeds into the fastening portion. The quick-release fixing structure includes a limiting member mounted on the first side wall, the limiting member having a mounting groove. A drive plate is movably disposed within the mounting groove, the drive plate having a drive slide rail and a recess. When the top cover is closed on the housing, the recess corresponds to the position of the fastening portion, causing the protrusion to embed within the recess. An elastic member is disposed within the mounting groove, and the elastic member abuts against the second side wall of the mounting groove and the drive plate. A knob is disposed on the first side wall, one side of the knob having a protrusion located in the drive slide rail. When the knob is rotated, the protrusion drives the drive plate, and the recess moves accordingly to press the protrusion away from the fastening portion, thereby opening the top cover relative to the housing.

[0007] The limiting member is characterized in that it further includes a guide and a stop. The guide is disposed on the top of the limiting member along a first axial direction to guide the drive plate to press the protrusion away from the fastening portion. The stop is disposed on the top of the limiting member along a second axial direction and adjacent to the guide to restrict the movement of the drive plate.

[0008] The knob is characterized in that a torsion part is provided on the other side opposite to the protruding rod, and the torsion part is exposed outside the first side wall.

[0009] The limiting member is characterized in that it further includes an adjacent mounting groove on the mounting plate, and the limiting member is mounted on the first side wall via the mounting plate.

[0010] The characteristic feature is that the drive slide rail further includes a first protruding rod space, disposed along a first axial direction. A second protruding rod space is adjacent to the first protruding rod space and disposed along a second axial direction. A moving space is located between the first protruding rod space and the second protruding rod space.

[0011] The present invention also provides a receiving box with a quick-release fixing structure, including a shell, a top cover, and a quick-release fixing structure. One first sidewall of the shell has a mounting hole, and the top of the first sidewall also has a fastening portion. The top cover covers the shell and has a protruding post; when the top cover is closed on the shell, the protruding post is located within the fastening portion. The quick-release fixing structure, installed on the first sidewall of the shell, includes a limiting member installed on the first sidewall, the limiting member having a mounting groove corresponding to the position of the mounting hole. A drive plate is movably disposed within the mounting groove, the drive plate having a drive slide rail, and the top of the drive plate having a recessed buckle; when the top cover is closed on the shell, the buckle corresponds to the position of the fastening portion, causing the protruding post to be located within the recessed buckle. An elastic member is disposed in the mounting groove, and the elastic member abuts against the second sidewall of the mounting groove and the drive plate. A knob is disposed within the mounting hole, and one side of the knob has a protruding rod that passes through the drive slide rail. When the knob is turned, the protruding rod drives the drive plate, and the corresponding buckle moves to press the protruding post away from the fastening part, thereby opening the top cover relative to the housing.

Detailed Implementation

[0018] To facilitate understanding and implementation of the present invention by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] The present invention is a quick-release fixing structure and a housing box with a quick-release fixing structure, which can quickly open and lock the top cover covering the shell, and can avoid the gap between the top cover and the shell in order to reserve the lock head.

[0020] Please refer to Figure 1 and Figure 2The receiving box 1 with a quick-release fixing structure includes a housing 10, a top cover 20, and a quick-release fixing structure 30. The quick-release fixing structure 30 is mounted on the housing 10. When the top cover 20 covers the housing 10, the quick-release fixing structure 30 can lock the top cover 20 onto the housing 10. Operating the quick-release fixing structure 30 allows for quick and easy unlocking to open the top cover 20, and the design of the quick-release fixing structure 30 also prevents gaps from forming between the top cover 20 and the housing 10.

[0021] The housing 10 includes a base plate 12 and a plurality of first sidewalls 14. In this embodiment, two first sidewalls 14 are arranged perpendicular to the base plate 12 and are parallel to each other. At least one of the first sidewalls 14 is provided with a mounting hole 120, and the top of the first sidewall 14 is also provided with a fastening part 122. In this embodiment, the fastening part 122 is an L-shaped groove design.

[0022] The upper cover 20 covers the housing 10 and includes a first base plate 21, protrusions 22, and fixing plates 24. The protrusions 22 are embedded in the fastening part 122. This embodiment has two fixing plates 24, which are respectively vertically arranged on both sides of the upper cover 20. The protrusions 22 can be arranged perpendicularly to the fixing plates 24 and extend parallel to the first base plate 21 of the upper cover 20.

[0023] Please refer to Figures 1 to 3 A quick-release fixing structure 30 is mounted on the first sidewall 14. The quick-release fixing structure 30 includes a limiting member 32, a drive plate 34, an elastic member 36, and a knob 38. The limiting member 32 is mounted on the first sidewall 14. In this embodiment, the limiting member 32 includes a second base plate 31, a plurality of second sidewalls 320a, a guide member 322, a stop piece 324, and a mounting plate 326. The second base plate 31 and the plurality of second sidewalls 320a form a mounting groove 320.

[0024] The mounting groove 320 is positioned corresponding to the mounting hole 120. The guide 322 is disposed on top of the limiting member 32, located on the second substrate 31, and extends along a first axial direction, which in this embodiment is the Z-axis direction.

[0025] The stop plate 324 is positioned on the top of the limiting member 32, located on the second substrate 31, and adjacent to the guide member 322 along the second axial direction. In this embodiment, the second axial direction is the X-axis direction. The first axial direction is perpendicular to the second axial direction, and the X-axis direction is perpendicular to the Z-axis direction. The mounting plate 326 is connected to the second sidewall 320a and adjacent to the mounting groove 320. The mounting plate 326 extends substantially perpendicular to the second sidewall 320a. In this embodiment, multiple mounting plates 326 surround the mounting groove 320, and the limiting member 32 can be mounted on the first sidewall 14 through the mounting plates 326. This embodiment also includes multiple locking components 40 passing through the mounting plates 326, thereby fixing the limiting member 32 to the first sidewall 14.

[0026] A drive plate 34 is disposed within a mounting groove 320, and the drive plate 34 is provided with a drive slide rail 340 and a recess 342. In this embodiment, the drive slide rail 340 is located at the center of the drive plate 34, and the shape of the drive slide rail 340 can be triangular, such as a right triangle. The drive slide rail 340 includes a first protruding rod space 340a, a second protruding rod space 340b, and a moving space 340c. The first protruding rod space 340a is arranged along a first axial direction, such as the Z-axis direction. The second protruding rod space 340b is adjacent to the first protruding rod space 340a and is arranged along a second axial direction, such as the X-axis direction. The moving space 340c is located between the first protruding rod space 340a and the second protruding rod space 340b, and the first protruding rod space 340a, the second protruding rod space 340b, and the moving space 340c are connected to form a triangular drive slide rail 340.

[0027] The recess 342 is located on the top of the drive plate 34. When the top cover 20 covers the housing 10, the recess 342 corresponds to the position of the fastening part 122, so that the protrusion 22 of the top cover 20 will be embedded in the recess 342 and the fastening part 122.

[0028] The elastic element 36 is disposed within the mounting groove 320 and abuts against the second sidewall 320a of the mounting groove 320 and the drive plate 34. Furthermore, the elastic element 36 is located between the second sidewall 320a of the mounting groove 320 and the drive plate 34. There may be one or more elastic elements 36. In this embodiment, the elastic element 36 includes a first Z-shaped spring piece 362 and a second Z-shaped spring piece 364 perpendicularly connected to each other. The first Z-shaped spring piece 362 is disposed along the Z-axis, and the second Z-shaped spring piece 364 is disposed along the X-axis. The first Z-shaped spring piece 362 applies a force in a first direction D1 to the drive plate 34, and the second Z-shaped spring piece 364 applies a force in a second direction D2 to the drive plate 34. The first direction D1 is perpendicular to the second direction D2.

[0029] The knob 38 is rotatably disposed within the mounting hole 120 of the housing 10. A protrusion 382 is provided on one side of the knob 38, located in the drive slide rail 340. The shape of the protrusion 382 perfectly matches the first protrusion space 340a and the second protrusion space 340b. When the knob 38 is rotated, the protrusion 382 moves the drive plate 34, pressing the protrusion 22 of the upper cover 20 away from the fastening part 122, allowing the upper cover 20 to open relative to the housing 10. In this embodiment, a torsion part 384 is also provided on the other side of the knob 38 opposite to the protrusion 382, ​​and the torsion part 384 protrudes outside the first sidewall 14, providing the user with the ability to apply force to torsion the knob 38.

[0030] Please refer to Figure 4 and Figure 5 This is to illustrate the usage state of the upper cover 20 to be opened in this embodiment. For example... Figure 4As shown, when the upper cover 20 is closed to the housing 10, the recess 342 corresponds to the position of the fastening part 122, causing the protrusion 22 of the upper cover 20 to engage with the fastening part 122 of the housing 10 and the recess 342 of the drive plate 34. Because the elastic member 36 applies pressure in the first direction D1 and the second direction D2 to the drive plate 34, the drive plate 34 abuts against the stop plate 324 and the mounting groove 320, and abuts against the second sidewall 320a of the mounting groove 320. In other words, the stop plate 324 prevents the drive plate 34 from moving in the second direction D2, and the second sidewall 320a of the groove 320 prevents the drive plate 34 from moving in the first direction D1. Therefore, the drive plate 34 can be restricted to the first position. In addition, the protrusion 382 of the knob 38 is located in the first protrusion space 340a along the Z-axis direction, and the shape of the protrusion 382 matches the first protrusion space 340a, also providing a restricting force for the drive plate 34 in the first position. The first direction D1 is perpendicular to the second direction D2. In addition, the first direction D1 can be parallel to the X-axis direction, and the second direction D2 can be parallel to the Y-axis direction.

[0031] Please refer to Figure 5 To open the top cover 20 of the housing 10, the knob 38 is rotated in the third direction D3. When the knob 38 is rotated, the protrusion 382 rotates in the third direction D3, simultaneously pushing the drive plate 34 to move in the fourth direction D4. At the same time, the recess 342 of the drive plate 34 moves accordingly to push the protrusion 22 to move in the fourth direction D4. As the drive plate 34 moves, the rotating protrusion 382 enters the moving space 340c of the drive slide rail 340, and then the drive plate 34 moves, causing the protrusion 382 to enter the second protrusion space 340b. The fourth direction D4 is parallel to the first direction D1 but opposite in direction. When the top of the drive plate 34 moves away from the restrained position of the stop plate 324 along the fourth direction D4, the drive plate 34 moves in the second direction D2 to reach the second position due to the force provided by the elastic member 36, thus pressing the protrusion 22 away from the latching part 122 to open the top cover 20. Figure 5 In the middle, guide member 322 can prevent drive plate 34 from moving in the fourth direction D4, guiding drive plate 34 to press protrusion 22 away from fastening part 122. Stop plate 324 can prevent drive plate 34 from moving in the fourth direction D4. Figure 4 The drive plate 34 moves in the first direction D1. In addition, the shape of the protrusion 382 also matches the second protrusion space 340b, providing a force to restrict the drive plate 34. Therefore, the drive plate 34 can be restricted to the second position.

[0032] Please refer to Figure 6 and Figure 7 This illustrates the closed state of the top cover 20 in this embodiment. For example... Figure 6As shown, when the top cover 20 is relative to the open housing 10, the drive plate 34 is in the second position. When the user wants to close the top cover 20, a force in the fifth direction D5 is applied to the top cover 20. At this time, the protrusion 22 also presses the drive plate 34 to move in the fifth direction D5. The fifth direction D5 is parallel to the second direction D2 but opposite in direction. The movement of the drive plate 34 causes the protrusion 382 to move along... Figure 5 The third party rotates towards D3, and the movement of the drive plate 34 causes the protrusion 382 to rotate from the second protrusion space 340b to the moving space 340c.

[0033] Please refer to Figure 7 After the drive plate 34 moves along the fifth direction D5 to a position away from the restriction position of the guide 322, the force provided by the elastic member 36 in the first direction D1 will be applied, moving the drive plate 34 in the first direction D1. The protrusion 382 will then rotate from the moving space 340c to the first protrusion space 340a. Simultaneously, because the buckle 342 still holds the protrusion 22, the protrusion 22 can slide into the fastening part 122, and the drive plate 34 will also slide into the position of the stop plate 324. The stop plate 324 restricts the force of the elastic member 36 in the second direction D2, thus restricting the drive plate 34 to the first position, allowing the upper cover 20 to close within the housing 10. Furthermore, the protrusion 382 of the knob 38 is positioned along the Z-axis in the first protrusion space 340a, and the shape of the protrusion 382 also matches the shape of the first protrusion space 340a, thus providing a restrictive force for the drive plate 34 in the first position.

[0034] As described above, the present invention can quickly open and lock the top cover covering the housing, and can avoid creating a gap between the top cover and the housing in order to reserve the lock head.

[0035] In summary, this invention meets the requirements for an invention patent, and therefore a patent application is filed in accordance with the law. However, the above description is merely a preferred embodiment of the invention, and the scope of the invention is not limited to the described embodiments.
