Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

Embodiment one

As shown in Figure 1, a ceiling installation structure mainly includes a hanging plate 1, a hook 2, an electrical connecting female end 3 and an electrical connecting male end 4, the electrical connecting female end 3 is fixedly connected to the hanging plate 1 and used for Connected to an external power supply cable, the hook 2 and the electrical connection male end 4 are fixedly connected to the component to be assembled 5, the electrical connection male end 4 is electrically connected to the device in the component to be assembled 5, and the electrical connection female end 3 is connected to the The electrical connection male end 4 is plugged and connected along the first direction. When the electrical connection female end 3 and the electrical connection male end 4 are plugged together, the power supply to the assembly part 5 is realized. The clamping part 11 has a movable area for the hook 2 to move along the second direction to adjust the part 5 to be assembled, and the two ends of the clamping part 11 along the second direction are respectively provided with limiting parts 12, The limiting part 12 plays a limiting role on the hook 2, prevents the hook 2 from coming out of the clamping part 11, and maintains the mating connection state between the hook 2 and the clamping part 11, that is, always keeps the hook 2 and the hanging plate 1 assembled In the state in place, the second direction is perpendicular to the first direction, and the electrical connection female end 3 and the electrical connection male end 4 can move relatively in the second direction and maintain electrical connection, because the hook 2 and the electrical connection male end Both ends 4 are fixedly connected to the parts to be assembled 5, and when the hook 2 moves along the second direction relative to the clamping part 11 on the hanging plate 1, the electrical connection male end 4 will also move along the second direction relative to the electrical connection female end 3. Since the second direction is perpendicular to the first direction, no matter how the hook 2 moves along the second direction in the clamping part 11, no amount of activity in the first direction will be generated, so as to electrically connect the female end and the electrical connection. The connection male end maintains a stable plugging state, and there will be no further mating or separation between the electrical connection female end and the electrical connection male end, maintaining a reliable electrical connection state and ensuring stable power supply.

In order to realize that the electrical connection female end 3 and the electrical connection male end 4 can also move relatively in the second direction and maintain electrical connection when the hook 2 moves in the second direction relative to the clamping part 11, it is necessary to electrically connect the female end 3 and the electrical connection male end 4. At least one of the electrical connection male terminals 4 has a conductive portion extending along the second direction. Assuming that the second direction is a straight line direction, the electrical connection female end 3 is provided with a conductive part extending along the second direction, that is, the electrical connection female end 3 is provided with a strip-shaped conductive part along the second direction, and the electrical connection The male end 4 is provided with a conductive shrapnel elastically abutting against the wall surface of the conductive part of the electrical connection female end 3. When the electrical connection male end 4 moves in the second direction relative to the electrical connection female end 3, the electrical connection male end 4 The conductive shrapnel slides along the wall surface of the conductive part electrically connected to the female terminal 3, and always maintains a stable electrical connection state without interruption of power supply.

In this embodiment, the described parts 5 to be assembled can be electronic devices such as projectors and audio equipment. When these electronic devices are installed, they have certain requirements for the direction of installation. Taking a projector as an example, when installing What needs to be adjusted is the projection orientation angle. In other words, the to-be-assembled part 5 needs a rotational degree of freedom in the circumferential direction to adjust the lens orientation of the projector, so that the lens of the projector is facing the projection screen, thereby ensuring the projection effect, so that the second direction It is a circular direction, and the hook 2 moves in the second direction relative to the clamping part 11, that is, the to-be-assembled part 5 rotates relative to the hanging plate 1, so as to realize the function of adjusting the direction of the to-be-assembled part 5. Specifically, the The first direction is vertical, and the second direction is a circular direction along the horizontal plane; or, for some audio equipment, it is necessary to adjust the sound direction during installation, so that the audio equipment will appear in a specified direction. sound, so that users can obtain a better hearing experience. Then, it is also possible to rotate and adjust the to-be-assembled part 5 to adjust the sound output direction of the audio equipment in the same manner as the projector above.

Since the second direction is an annular direction, the electrical connection female end 3 and the electrical connection male end 4 are a mating structure that can rotate relative to the second direction. Specifically, the electrical connection male end 4 is provided with a The two directions are concentric circular conductive parts, and the electrical connection female end 3 is provided with a conductive shrapnel abutting against the wall surface of the circular conductive part. When the electrical connection male end 4 is opposite to the electrical connection female end 3 along the second When the direction is turned, the conductive shrapnel slides along the wall of the circular conductive part, and always maintains a stable electrical connection state to ensure stable power supply; more specifically, the electrical connection female end 3 is provided with a circular slot to Cooperate with the annular conductive part on the electrical connection male end 4, and set a conductive shrapnel in the annular slot, and the conductive shrapnel elastically abuts against the wall surface of the annular conductive part to ensure the stability of the electrical connection , The conductive shrapnel can be arranged only one in the annular slot, or several can be arranged at intervals along the circumferential direction in the annular slot, so as to further improve the stability of the electrical connection. The electrical connection male terminal 4 specifically includes a live wire conductive part and a neutral wire conductive part, the live wire conductive part and the neutral wire conductive part are arranged in a concentric ring structure, and the corresponding electrical connection female end 3 is also provided with a live wire slot and a neutral wire. The wire slot, the live wire slot and the neutral wire slot form a concentric circular groove structure, the live wire conductive shrapnel is set in the live wire slot, and the neutral wire conductive shrapnel is set in the neutral wire slot, so as to electrically connect the female end 3 and the electrical connection When the male terminal 4 is docked, the electrical connection between the conductive part of the live wire and the conductive shrapnel of the live wire and the electrical connection of the conductive part of the neutral wire and the conductive shrapnel of the neutral wire are realized at the same time. The electrical connection male ends 4 can be rotated relative to each other, so that the orientation of the component to be assembled 5 can be adjusted and a stable power supply can be maintained.

In this embodiment, the hanging plate 1 and the hook 2 are made of sheet metal parts, which are simple in structure and high in strength, and can meet the requirements of high load-bearing capacity. The installation hole connected to the ceiling and the assembly hole for fixing the electrical connection female end 3, the peripheral edge of the hanging tray 1 is flanged to form the clamping part 11, specifically, the outer peripheral edge of the hanging tray 1 is radially Flanging processing is carried out on the inner side. The clamping portion 11 is specifically an L-shaped flange, which has a simple structure, high strength, and takes up little space. The clamping portion 11 is specifically arranged with three sections in the circumferential direction, and adjacent clamping portions Between 11 is a gap without a flanging structure, so that the hook 2 can pass through the gap to enter and exit the clamping part 11. Each clamping part 11 covers an arc segment along the second direction. In this embodiment, each clamping part 11 The angle range of the arc section covered by the part 11 is 50-60°, that is to say, when the hook 2 moves along the second direction on the clamping part 11, the part 5 to be assembled can be rotated by 50-60° in the circumferential direction. The adjustment range is large, which can flexibly meet various needs; the hook 2 is L-shaped, simple in structure, high in strength, and takes up little space. The three hooks 2 are distributed at intervals along the second direction, and the three hooks 2 are connected as a whole and processed by a sheet metal part, which further improves the structural strength, can increase the bearing capacity, and meets the demand for high load.

The limiting parts 12 at both ends of the clamping part 11 along the second direction are folded edges processed by sheet metal, which are easy to process and have good structural stability. They effectively limit the hook 2 and prevent the hook 2 from Breaking out of the clamping part 11 ensures a stable relationship between the hook 2 and the clamping part 11, that is, ensures a stable connection between the hanging plate 1 and the hook 2, and avoids the dangerous situation of loosening and falling of the part 5 to be assembled. Further, at least one of the limiting parts 12 at both ends of the clamping part 11 is provided with an opening 13 for the hook 2 to enter and exit the clamping part 11, and the position of the opening 13 is higher than that of the clamping part 11. In other words, there is a distance along the first direction between the opening 13 and the engaging portion 11, so that if the hook 2 is to withdraw from the engaging portion 11, it is necessary to lift the part 5 to be assembled upwards so that the hook 2 reaches the opening 13. position, and then turn it to separate the hook 2 from the hanging plate 1, and in the natural state after assembly, due to gravity, the hook 2 is always attached to the clamping part 11, and then just rotate the part 5 to be assembled If it is impossible to make the hook 2 withdraw from the clamping part 11, the hook 2 will be effectively restricted by the limit part 12, so as to ensure the stability of the connection, and there will be no dangerous situation that the assembly part 5 will fall off;

It is also possible not to set an opening at the limit part, for example, the hook is an elastic structure (the hook itself is elastic, or the hook is driven by an elastic member), and it is directly snapped into the limit part through the elastic activity of the hook, so that there is no need to set up for the hook to enter and exit The opening of the clamping part; the hook 2 of this embodiment adopts a rigid structure, which has good structural stability, strong bearing capacity, can carry heavier parts to be assembled, and has higher reliability and safety. Therefore, the opening 13 is adopted. A way for the hook 2 to enter and exit the engaging portion 11 .

The hanging plate 1 is provided with an indicating arrow of the installation direction. When the hanging plate 1 is installed on the ceiling, the indicating arrow is directed to the direction where the projection screen is located, so as to ensure that the hook 2 moves along the second direction on the clamping part 11 It can make the lens of the projector face the projection screen. Because the adjustment range is limited, it cannot be rotated 360° arbitrarily. If the hanging plate 1 is not installed correctly, it may happen that no matter how you adjust it, the lens of the projector will not be able to face directly. projection screen.

In this embodiment, the hanging plate 1 is further provided with a guide part 61, and the fitting part 5 is provided with a matching part 62, and the guide part 61 and the matching part 62 guide and cooperate along the first direction, and through the guide part The cooperation between the 61 and the mating part 62 enables the electrical connection female end 3 and the electrical connection male end 4 to be plugged in more accurately and conveniently, avoiding that the electrical connection female end and the electrical connection male end are difficult to align and affect the installation efficiency. Specifically, The guide part 61 is a convex structure, while the matching part 62 is a groove structure, the groove structure has an inclination angle, the mouth is wide and the bottom is narrow to play a guiding and positioning role, because the parts to be assembled are adjusted in the second direction relative to the hanging plate degree of freedom, and the second direction is circular, so that the guide part 61 and the matching part 62 need to be able to rotate relative to each other along the second direction, so the matching part 62 has a circular groove, and the guide The part 61 is a cylindrical protrusion or a part of a cylindrical protrusion. The guide part 61 and the matching part 62 should not only play the role of positioning and guiding, but also need to be able to rotate relatively. When installing, the guide part 61 should be inserted into the matching part 62 first. , so that the electrical connection female end 3 and the electrical connection male end 4 are facing each other, the guide portion 61 continues to penetrate into the matching portion 62 , and the electrical connection female end 3 and the electrical connection male end 4 are plugged together again.

The hanging plate 1 is also connected with a wire harness cover 7, and the wire harness cover 7 is used to cover the external cables connected to the electrical connection female end 3, so as to protect the external cables and ensure the rotation of the parts to be assembled The external cable will not be scratched during operation, ensuring the safety and reliability of power supply.

Further, the hanging plate 1 is also connected with an alignment member 8, and the alignment member 8 cooperates with the peripheral edge of the to-be-assembled part 5 for positioning, so as to realize visual alignment installation and avoid repeated debugging due to blind operation , to improve installation efficiency, the alignment member 8 mainly plays the role of aligning the electrical connection female end 3 and the electrical connection male end 4, and when the peripheral edge of the to-be-assembled member 5 reaches a mating state with the alignment member 8, it only needs to be connected again Pushing up the part 5 to be assembled can make the electrical connection female end 3 and the male end 4 plugged together. Specifically, the alignment part 8 is provided with a first positioning part 81 located on the outside of the part to be assembled 5, and the part to be assembled The peripheral edge of 5 is positioned against the first positioning part 81 for positioning. The part 5 to be assembled is specifically a projector, and the projector is in the shape of a round cake as a whole. The portion 81 is arc-shaped, and the peripheral edge of the projector abuts against the radial inner side of the first positioning portion 81, which means that the electrical connection female end 3 and the electrical connection male end 4 are aligned;

The alignment member 8 is also provided with a second positioning portion 82 for positioning in the second direction. After the electrical connection female end 3 and the electrical connection male end 4 are aligned, the position of the hook 2 relative to the hanging plate 1 needs to be adjusted. Otherwise, the hook 2 cannot enter the clamping part 11, and the second positioning part 82 is used to position the component 5 to be assembled in the circumferential direction, so that the hook 2 on the component 5 to be assembled is just in between the adjacent clamping parts 11 The gap between them, and then push up the assembly part 5 and then rotate it to make the hook 2 enter into the clamping part 11 to achieve a reliable connection. Specifically, the second positioning portion 82 may be a structure such as a protrusion or a notch, or may be a mark, a scale, or the like.
