Description

Technical Field

[0001] The invention relates to the technical field of downlight installation, in particular to an embedded concealed downlight wire box. Background Art

[0002] Downlights are a kind of lighting equipment with exquisite design, which are famous for their evenly distributed light and wide beam angle. The installation forms are mainly divided into open installation and concealed installation. At present, conventional concealed downlights are combined with ceilings and fixed to the ceilings by spring clips, which can form a warm and soft atmosphere in combination with the design scheme.

[0003] However, since the downlight is fixed by spring clips on both sides, after long-term use, the elasticity is reduced and it is easy to cause the downlight to loosen, which will not only leave a gap between the downlight and the ceiling, affecting the appearance, but may even cause the downlight to fall. Summary of the invention

[0004] The present invention aims to provide an embedded concealed downlight wire box which improves the installation stability of the downlight and avoids loosening or falling.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows.

[0006] An embedded concealed downlight wire box includes a box body and a bottom cover, wherein the outer surfaces of the four sides of the box body are provided with two wiring holes, and the four corners of the bottom of the box body are provided with screw holes. Through holes are provided at the four corners of the bottom cover surface, and the surface of the bottom cover is provided with mounting holes. Limiting blocks are installed on both sides of the upper surface of the bottom cover through a first elastic mechanism, and a card slot is provided on the lower surface of the limiting block, and a second elastic mechanism capable of plugging and cooperating with the card slot is provided inside the bottom cover.

[0007] It can be seen that after the downlight is installed in the mounting hole, the spring clips on both sides of the downlight are respectively pressed against the upper surface of the bottom cover, and the limit block is pushed to resist the spring clip through the first elastic mechanism, and the limit block is fixed by the plug-in cooperation with the card slot, so that the limit blocks on both sides can limit the spring clips on both sides of the downlight respectively, thereby preventing the spring clips from being unable to support the downlight due to reduced elasticity and being stretched to both sides, causing the downlight to loosen, and avoiding a gap between the downlight and the ceiling that affects the appearance and causes it to fall, and the entire wire box can be pre-buried in the floor in advance, and the downlight can be installed in the wire box after the pipeline is connected according to the secondary electromechanical detailed drawing, thereby eliminating the suspended ceiling, increasing the net height of the space, saving the cost of the suspended ceiling, and since the wire box is pre-buried in advance and installed on-site, there is no need to consider the installation effect error caused by the workers' craftsmanship.

[0008] Furthermore, the first elastic mechanism includes a fixed block installed on the upper surface of the bottom cover, a first telescopic rod is installed on the outer surface of the fixed block, an end of the first telescopic rod is connected to the limit block, a first spring is sleeved on the outer surface of the first telescopic rod, and both ends of the first spring are respectively abutted against the fixed block and the limit block.

[0009] The first telescopic rod provides a supporting effect for the limit block, and an elastic force is applied to it through the first spring. When installing the downlight, first straighten the spring clips on both sides of the downlight upwards, and then push the downlight upward from the mounting hole. After being pushed up, the spring clip automatically flips downward and pushes the limit block away, so that the end of the spring clip abuts against the upper surface of the bottom cover, and the limit block abuts against the spring clip under the elastic force of the first spring.

[0010] Furthermore, the second elastic mechanism includes an inner groove opened inside the bottom cover, a guide rod is arranged inside the inner groove, a clamping block is installed on the upper surface of the guide rod, a side groove is opened on the inner wall of the inner groove, a shoulder is installed on the outer surface of the guide rod, and a second spring is sleeved on the outer surface of the guide rod, and both ends of the second spring are respectively abutted against the shoulder and the inner wall of the side groove.

[0011] When the limit block abuts against the spring clip, the slot is just above the block. At this time, the elastic force of the second spring can be used to drive the guide rod to move upward and insert the block into the slot, thereby fixing the limit block and enabling it to limit the spring clip.

[0012] Furthermore, an iron block is installed at the bottom of the guide rod.

[0013] Before installing or removing the downlight, it is necessary to first pull the card block out of the card slot and cancel the fixation of the limit block. Therefore, a magnet can be placed on the lower surface of the bottom cover and adsorb the iron block. The iron block moves downward under the action of the magnet, so it can drive the card block to be pulled out of the card slot. When the magnet is removed, the card block can be reset under the elastic force of the second spring.

[0014] Furthermore, a groove is provided on the lower surface of the bottom cover, and the groove is coaxially arranged with the mounting hole. A plurality of second telescopic rods are installed inside the groove, and an annular plate is commonly installed at the ends of the plurality of second telescopic rods. A third spring is sleeved on the outer surface of the second telescopic rod, and the two ends of the third spring are respectively abutted against the inner wall of the groove and the annular plate.

[0015] At present, when the downlight is installed, its bottom shell is located on the outside of the ceiling, which is used to cooperate with the spring clip to complete the installation of the downlight. Through the setting of the groove, the bottom shell of the downlight can be stored in the groove, so that the downlight can be installed without protruding parts, the flatness of the entire ceiling is improved, and it is more tidy and beautiful. Through the setting of the second telescopic rod and the third spring, the downlight can have a certain upward activity space after installation. Since the limit block is subjected to the force of the spring clip, the limit block will abut against the inner wall of the slot, and there is a certain friction between the two, which will make it difficult for the iron block to fall under the action of the magnet. Therefore, the downlight can be pushed upward to drive the spring clip to rotate slightly and separate from the limit block. At this time, the limit block moves slightly under the push of the first spring, and the card block is separated from the inner wall of the slot, so that the iron block can be easily sucked down by the magnet.

[0016] Furthermore, four corners of the lower surface of the bottom cover are provided with clearance grooves, and the clearance grooves are coaxially arranged with the through hole.

[0017] By setting the clearance groove, the bolts can be hidden to avoid affecting the subsequent puttying.

[0018] Furthermore, the dimensions of the box body are 120×120×90 mm, and the dimensions of the bottom cover are 120×120×10 mm.

[0019] Compared with the prior art, the space around the wire box has been expanded by 20mm, thereby improving the heat dissipation effect of the downlight.

[0020] Furthermore, the number of the second telescopic rods is four, and the four second telescopic rods are distributed in a coaxial array.

[0021] By providing the four second telescopic rods, a uniform elastic force can be provided to the annular plate, resulting in a better use effect.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the present invention; The second elastic mechanism is plugged into the card slot to fix the limit block, so that the limit blocks on both sides can limit the spring clips on both sides of the downlight respectively, thereby preventing the spring clips from being unable to support the downlight due to reduced elasticity and being stretched to both sides, causing the downlight to loosen, and preventing a gap between the downlight and the ceiling from affecting the appearance, and preventing the downlight from falling; By setting the groove, the bottom shell of the downlight can be stored in the groove, so that the downlight can be installed without protruding parts, thereby improving the flatness of the entire ceiling and making it more neat and beautiful.

Limiting blocks 106 are installed on both sides of the upper surface of the bottom cover 103 through a first elastic mechanism 200, and a card slot 107 is provided on the lower surface of the limiting block 106. A second elastic mechanism 300 that can be plugged and matched with the card slot 107 is provided inside the bottom cover 103.

[0027] After the downlight is installed in the mounting hole 105, the spring clips on both sides of the downlight are respectively pressed against the upper surface of the bottom cover 103, and the limiting block 106 is pushed to press against the spring clip by the first elastic mechanism 200, and the limiting block 106 is fixed by the plug-in cooperation with the card slot 107 by the second elastic mechanism 300, so that the limiting blocks 106 on both sides can limit the spring clips on both sides of the downlight respectively, thereby preventing the spring clips from being unable to support the downlight due to reduced elasticity and being stretched to both sides, causing the downlight to loosen, and avoiding a gap between the downlight and the ceiling that affects the appearance and causes it to fall, and the entire wire box can be pre-buried in the floor slab in advance, and the downlight can be installed in the wire box after the pipeline is connected according to the secondary electromechanical detailed drawing, thereby eliminating the suspended ceiling, increasing the net height of the space, saving the cost of the suspended ceiling, and because the wire box is pre-buried in advance and installed on-site, there is no need to consider the installation effect error caused by the workers' craftsmanship.

[0028] Specifically, the first elastic mechanism 200 includes a fixed block 201 installed on the upper surface of the bottom cover 103, and a first telescopic rod 202 is installed on the outer surface of the fixed block 201. The end of the first telescopic rod 202 is connected to the limit block 106, and the outer surface of the first telescopic rod 202 is sleeved with a first spring 203. The two ends of the first spring 203 are respectively abutted against the fixed block 201 and the limit block 106. The first telescopic rod 202 provides a supporting effect for the limit block 106, and an elastic force is applied to it by the first spring 203. When installing the downlight, first straighten the spring clips on both sides of the downlight upwards, and then push the downlight upward from the mounting hole 105. After pushing it up, the spring clip automatically flips downward and pushes the limit block 106, so that the end of the spring clip abuts against the upper surface of the bottom cover 103, and the limit block 106 abuts against the spring clip under the elastic force of the first spring 203.

[0029] Specifically, the second elastic mechanism 300 includes an inner groove 301 opened inside the bottom cover 103, a guide rod 302 is arranged inside the inner groove 301, a clamping block 306 is installed on the upper surface of the guide rod 302, a side groove 303 is opened on the inner wall of the inner groove 301, a shoulder 304 is installed on the outer surface of the guide rod 302, a second spring 305 is sleeved on the outer surface of the guide rod 302, and the two ends of the second spring 305 are respectively abutted against the shoulder 304 and the inner wall of the side groove 303. When the limit block 106 abuts against the spring clip, the clamping groove 107 is just above the clamping block 306. At this time, the elastic force of the second spring 305 can be used to drive the guide rod 302 to move upward, and the clamping block 306 can be inserted into the clamping groove 107, thereby completing the fixation of the limit block 106 so that it can limit the spring clip.

[0030] Specifically, an iron block 400 is installed at the bottom of the guide rod 302.

Since the limit block 106 is subjected to the force of the spring clip, the limit block 106 will abut against the inner wall of the card slot 107, and there is a certain friction between the two, which will make it difficult for the iron block 400 to fall under the action of the magnet. Therefore, the downlight can be pushed upward to drive the spring clip to rotate slightly and separate from the limit block 106. At this time, the limit block 106 moves slightly under the push of the first spring 203, and the card block 306 is separated from the inner wall of the card slot 107, so that the iron block 400 can be easily sucked down by the magnet.
