Specific embodiments

[0025] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the accompanying drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0026] Referring to the attached Figure 1 As shown, in this embodiment, a quick - installation ceiling recessed lamp without nails includes a lamp body 1 embedded in the installation hole 110 reserved in the ceiling 100. At least a pair of oppositely arranged side locking assemblies 4 are provided at the bottom of the lamp body 1. Taking Figure 2 as an example, the two side locking assemblies 4 in this embodiment are respectively arranged at the left and right sides of the bottom of the lamp body 1. Of course, those skilled in the art can also arrange them at the front and rear positions, and specific limitations are not made here.

[0027] Secondly, each side lock assembly 4 includes a connecting bracket 41 fixedly connected to the bottom of the lamp body 1, at least one connecting plate 42 arranged on the connecting bracket 41, an adjusting screw 43 whose two ends are respectively pivoted to the connecting bracket 41 and the connecting plate 42, and a pressing plate 44 threadedly connected to the adjusting screw 43, wherein the connecting bracket 41 is formed with a clamping plate 45 bent and extending to the outer edge of the mounting hole 110, and the connecting bracket 41 and the clamping plate 45 are integrally formed into a long strip structure with a "Z" shape in the longitudinal section. Specifically, the connecting bracket 41 can be pre-fastened and fixed to the edge of the bottom surface of the lamp body 1 by a plurality of screws, and after the lamp body 1 is embedded in the mounting hole 110, the clamping plate 45 is correspondingly exposed and placed below the outer edge of the mounting hole 110. The connecting plate 42 of this embodiment is pre-fixed on the connecting bracket 41 (with an attached Figure 2 For example, the connection here corresponds to the top surface of the connecting bracket 41 / clamp plate 45). The lower end of the adjusting screw 43 extends and is exposed at the bottom of the connecting bracket 41, that is, the adjusting screw 43 passes through the pre-opened holes of the connecting bracket 41 (actually the pressure plate 44) and the connecting plate 42 from bottom to top, and the lower end of the adjusting screw 43 is exposed at the bottom of the connecting bracket 41 (the end surface of the lower end is formed with a tool slot for a screwdriver to cooperate), and the upper end of the adjusting screw 43 is threadedly connected with a preset anti-loosening nut (the anti-loosening nut is pre-fixed on the top of the connecting plate 42 by welding or the like) after passing through the perforation of the connecting plate 42. In addition, the pressure plate 44 is correspondingly threadedly connected to the adjusting screw 43, wherein the pressure plate 44 will rotate synchronously with the rotation of the adjusting screw 43 when it is not restricted, and when the pressure plate 44 is subject to external rotation restrictions, the continuous rotation of the adjusting screw 43 will drive the pressure plate 44 to move up and down corresponding to the thread. Based on this, as the adjusting screw 43 rotates, the pressing plate 44 is driven to rotate and switch between the preset reverse avoidance state or the forward clamping state, wherein the pressing plate 44 in the reverse avoidance state avoids the inner edge position of the mounting hole 110, and conversely, the pressing plate 44 in the forward clamping state is placed above the inner edge position of the mounting hole 110; the connecting plate 42 stops and contacts the pressing plate 44 that is rotated and switched to the forward clamping state at the rated position, so that the pressing plate 44 gradually moves downward as the adjusting screw 43 continues to rotate forward, and the pressing plate 44 The clamping plate 45 is used to clamp the ceiling 100 so as to adapt to ceilings 100 of different thicknesses, that is, the pressing plate 44 is first switched to the forward clamping state as the adjusting screw 43 rotates, and then the pressing plate 44 and the connecting plate 42 are stopped and abutted to limit the rotation of the pressing plate 44 and gradually move downward until the pressing plate 44 presses against the top surface of the ceiling 100 and clamps the ceiling 100 with the clamping plate 45. The downward movement of the pressing plate 44 corresponds to ceilings 100 of different thicknesses. The greater the thickness, the smaller the downward movement, and vice versa, the smaller the thickness, the greater the downward movement.

[0028] In summary, during installation, the operator first rotates and switches the pressing plate 44 of each side locking component 4 to the reverse clearance state to avoid abnormal interference such as collision between the pressing plate 44 and the ceiling 100 during the process of the lamp body 1 being inserted into the installation hole 110 of the ceiling 100. After the lamp body 1 is completely inserted, the operator can use tools such as a screwdriver to rotate and tighten the adjusting screw 43 of each side locking component 4 one by one in the lower position, so that the pressing plate 44 rotates and switches to the forward clamping state and gradually moves down to cooperate with the clamping plate 45 to clamp the ceiling 100, thus realizing the quick installation operation of the lamp body 1 without additional operations such as nailing and drilling, greatly facilitating the actual installation operation and reducing the burden on the operator. On the contrary, during disassembly, the operator only needs to reverse-rotate and screw the adjusting screw 43 of each side locking component 4 to gradually move the pressing plate 44 upward and rotate and switch it to the reverse clearance state, and then the lamp body 1 can be removed from the installation hole 110, which is convenient for later maintenance work.

[0029] To improve the aesthetics, this embodiment further includes a bottom frame 3 detachably covering and embedded at the outer edge position of the installation hole 110. Among them, the bottom frame 3 includes an integrally formed vertical baffle 31 and a horizontal baffle 32. The vertical baffle 31 is a vertically extending annular structure, and the vertical baffle 31 is inserted into the installation hole 110 to laterally cover the side locking component 4; the horizontal baffle 32 is a horizontally extending annular structure, the inner end of the horizontal baffle 32 is connected to the bottom end of the vertical baffle 31 and the horizontal baffle 32 horizontally covers the side locking component 4. Thus, by using the covering effects of the vertical baffle 31 and the horizontal baffle 32 of the bottom frame 3 on the side locking component 4 in different directions, the aesthetics are greatly improved.

[0030] In this embodiment, to achieve the quick installation function between the bottom frame 3 and the connection bracket 41 / lamp body 1, specifically, at least one connection card seat 46 is provided on the bottom surface of the connection bracket 41, and connection blocks 5 that are in one-to-one correspondence and snap-fit with the connection card seats 46 are provided on the top surface of the bottom frame 3. Among them, each connection card seat 46 includes two accommodation cylinders 461 arranged with opposite openings and two snap-in marbles 462 respectively elastically embedded in the accommodation cylinders 461. A spring member 463 is provided in the accommodation cylinder 461, and both ends of the spring member 463 are respectively connected to the inner wall of the accommodation cylinder 461 and the snap-in marble 462. By using the elastic force exerted by the spring member 463 on the snap-in marble 462, the two snap-in marbles 462 in the two accommodation cylinders 461 are elastically pushed out in opposite directions. Secondly, a snap-in groove for the connection block 5 to be inserted into is formed between the two accommodation cylinders 461, and the two snap-in marbles 462 elastically press the connection block 5 inserted into the snap-in groove, and the elastic forces exerted by the snap-in marbles 462 from both sides of the connection block 5 are used to facilitate the connection block 5 to be firmly embedded in the snap-in groove.

[0031] Furthermore, the connecting clamping block 5 of this embodiment has an inverted trapezoidal structure that is wider at the top and narrower at the bottom. Among them, the two side surfaces of the connecting clamping block 5 are concave arc surfaces, so as to increase the contact area between the clamping marbles 462 and the connecting clamping block 5, making it more stable and reliable.

[0032] In this embodiment, at least one safety suspension rope 6 is provided between the connecting bracket 41 and the bottom frame 3. Among them, the two ends of the safety suspension rope 6 are respectively connected to the connecting bracket 41 and the bottom frame 3 through preset spring hooks. When the bottom frame 3 falls due to reasons such as installation errors and service life, the bottom frame 3 can be hoisted by means of the safety suspension rope 6 to prevent accidents such as injuring people and damaging items, improving safety.

[0033] In this embodiment, the above-mentioned spring hook belongs to a conventional hook structure and is not specifically limited here. It is commonly used in the fields of keychains and hanging lights. Those skilled in the art can select an appropriate spring hook structure.

[0034] In this embodiment, two connecting seat blocks 46 are provided on the bottom surface of each connecting bracket 41, and four connecting clamping blocks 5 that are respectively in one-to-one clamping fit with the respective connecting seat blocks 46 are provided on the top surface of the bottom frame 3.
