For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] A spliced ​​par light chassis, such as Figure 1-3 As shown, it includes a shell 1 and at least one connector 2; a plurality of snap-in groove structures 111 are evenly spaced on the outer wall of the shell 1, and a snap-in convex structure 211 adapted to the snap-in groove structure 111 is provided on both sides of the connector 2, and the snap-in convex structure 211 is snap-connected with the snap-in groove structure 111.

[0025] In this embodiment, the housing 1 is integrally formed from a high-strength aluminum alloy through a stamping or casting process, resulting in a lightweight design with excellent heat dissipation performance. The housing 1 is bowl-shaped, with six snap-fitting grooves 111 spaced evenly apart on its outer wall. The angle between two adjacent snap-fitting grooves 111 is 60°. The connector 2 is symmetrical, with snap-fitting protrusions 211 integrally formed on both sides. The snap-fitting grooves 111 mate with the snap-fitting protrusions 211, allowing the connector 2 to be removably snap-fitted to the housing 1. The snap-fitting protrusions 211 on both sides of the connector 2 allow the connector 2 to connect two housings 1 together. Furthermore, users can freely combine multiple housings 1 as needed to form a variety of shapes, such as straight lines, L-shapes, and circles.

[0026] The above-mentioned configuration of this utility model first simplifies the layout of traditional par lights and improves installation efficiency. Secondly, it enhances the flexibility and creativity of use. Users can choose different styles of products to build different lighting combinations according to their actual needs. In addition, the splicing combination of various shapes can meet the aesthetic requirements of different scenes and enhance the visual effect.

[0027] Furthermore, the snap-fit ​​groove structure 111 includes two outer grooves 1111 and two inner grooves 1112, and the two inner grooves 1112 are located between the two outer grooves 1111; two sliding guide blocks 1113 are formed between the two inner grooves 1112, and a snap-fit ​​groove 11131 is provided on the sliding guide block 1113; the two outer grooves 1111 and the two inner grooves 1112 are integrally formed with the outer shell 1.

[0028] like Figure 1 As shown, the snap-in groove structure 111 is in an inverted "convex" shape as a whole and is a symmetrical structure. An inner slide groove 1112 and an outer slide groove 1111 are respectively opened on both sides of the symmetry line, and at least one long strip of sliding guide block 1113 is formed between the two inner slide grooves 1112. In this embodiment, there are two sliding guide blocks 1113, and a snap-in groove 11131 is opened at the upper end of the sliding guide block 1113. The snap-in groove 11131 is used to snap-in the connector 2 to prevent the connector 2 from falling off from the shell 1 due to vibration, external force pulling, etc., thereby improving the connection reliability of the assembled combination of multiple par lights.

[0029] Furthermore, the connector 2 includes a snap-fit ​​seat 21 with a convex structure 211 on both sides, a snap-fit ​​block 22, a knob 24 and an upper cover 23; the snap-fit ​​seat 21 is fixedly connected to the upper cover 23 and forms a cavity for accommodating the snap-fit ​​block 22; the snap-fit ​​block 22 is rotatably connected to the snap-fit ​​seat 21; the knob 24 passes through the upper cover 23 and is fixedly connected to the snap-fit ​​block 22; the snap-fit ​​block 22 is movably inserted into the slot 11131 so that the convex structure 211 is snap-fitted to the snap-fit ​​slot structure 111.

[0030] like Figure 3-5 As shown, the clamping seat 21 is also made of high-strength aluminum alloy through a casting process, and a cam structure 211 is integrally formed on both sides. The cam structure 211 is used to slide into the clamping groove structure 111. After the cam structure 211 slides into the clamping groove structure 111 for a certain distance, it is blocked by the bottom of the clamping groove structure 111 and cannot continue to slide forward (in the direction of the par light). The upper cover 23 is installed on the top of the clamping seat 21 by four screws, and a through hole is provided in the center part. The knob 24 passes through this through hole and is fixedly connected to the clamping block 22 by screws. The clamping block 22 is located in the hollow cavity of the clamping seat 21, and is rotatably connected to the clamping seat 21 through a structure in which a pin shaft is sleeved on a pin hole. The clamping block 22 is runway-shaped, with the two ends in the long axis direction being the clamping ends, and is inserted into the clamping slot 11131 in a rotating manner to achieve a clamping effect. The upper cover 23 is provided with engaging holes 231 on both sides corresponding to the engaging protrusion structure 211 for the engaging end of the engaging block 22 to pass through.

[0031] Furthermore, the convex structure 211 includes two outer sliders 2111 that are adapted to the outer slide groove 1111 in one-to-one correspondence, and two inner sliders 2112 that are adapted to the inner slide groove 1112 in one-to-one correspondence. The two inner sliders 2112 are located between the two outer sliders 2111; the two outer sliders 2111, the two inner sliders 2112 and the clamping seat 21 are integrally formed.

[0032] like Figure 3-5 As shown, the latching convex structure 211 is generally inverted and symmetrical, with an inner slider 2112 and an outer slider 2111 formed on either side of the symmetry line. The inner slider 2112 and the outer slider 2111 have equilateral trapezoidal cross-sections along their respective lengths, so that the latching seat 21 can only slide upward to disengage from the housing 1, preventing the latching seat 21 from sliding radially in the housing 1.

[0033] Furthermore, both the outer sliding groove 1111 and the inner sliding groove 1112 are tapered grooves that gradually narrow from the upper end surface to the lower end surface.

[0034] like Figure 1 and Figure 3 As shown, the cross-sections of the outer slide groove 1111 and the inner slide groove 1112 in their respective length directions gradually narrow from top to bottom, facilitating assembly and disassembly of the connector 2 and the housing 1. Correspondingly, the cross-sections of the inner slider 2112 and the outer slider 2111 in their respective length directions gradually narrow from top to bottom.

[0035] Furthermore, four sleeves 212 are arranged at equal intervals on the clamping seat 21 and around the rotation center of the clamping block 22, and a ball 213 is placed on the top of the sleeve 212; four semicircular grooves 221 for adapting to the ball 213 are arranged at equal intervals on the lower end surface of the clamping seat 21 and around the rotation center of the clamping block 22; the lower end of the ball 213 is pressed against the sleeve 212, and the upper end thereof is movably pressed against the semicircular groove 221.

[0036] like Figure 3-5 As shown, four sleeves 212 are arranged in the cavity of the clamping seat 21 through an integrated molding process. The angle between two adjacent sleeves 212 is 90°. The top of the sleeve 212 also has a small groove for accommodating the ball 213, which plays the role of fixing the ball 213. When the knob 24 drives the clamping block 23 to rotate, the ball 213 also rolls along. When the semicircular groove 221 is located directly above the ball 213, the clamping end of the clamping block 22 is either located in the clamping groove 11131, or the clamping groove 11131 is misaligned by 90°. The semicircular groove 221 plays the role of strengthening the fixing of the ball 213, similar to the effect of a "gear position". The user does not need to visually observe the rotation angle of the clamping block 22, and can know by feel whether the rotation angle is an integer multiple of 90°.

[0037] Furthermore, the housing 1 includes an upper end cover 11 for accommodating the driving unit and a lower end cover 12 for accommodating the light-emitting unit, and the upper end surface is fixedly connected to the lower end cover 12 ; the snap-fit ​​groove structure 111 is located on the upper end cover 11 .

[0038] like Figure 1 As shown, the upper end cover 11 is fixedly connected to the lower end cover 12 by multiple screws. The upper end cover 1 is internally installed with electronic templates such as a drive unit, a PCB board, and a wireless receiver, and the lower end cover 12 is internally installed with a light-emitting unit and transparent protective glass.

[0039] Furthermore, a plurality of connecting side plates 3 are evenly spaced and clamped on the outer side wall of the lower end cover 12 . A plurality of screw holes 31 for connecting two connecting side plates 3 together are provided in an evenly spaced circumferential array on the connecting side plates 3 .

[0040] like Figure 1 、 Figure 6 、 Figure 7 As shown, six connecting side panels 3 are also evenly spaced on the outer wall of the lower end cover 12. The connecting side panels 3 are snapped onto the lower end cover 12 in a conventional, reusable, and removable manner. The connecting side panels 3 are staggered with the connector 2 to avoid interference between the two housings 1 in certain splicing shapes.

[0041] The two lower end covers 12 are assembled together by connecting the side panels 3. Figure 6 As shown, the two connecting side panels 3 are assembled together in a back-to-back manner and fixed together with three to four screws. The number of screw holes 31 on the connecting side panels 3 is eight, so that the angle between the two connected lower end covers 12 can be adjusted to any one of 0°, 45°, 90°, 135°, 180°, 225°, and 270°, further enriching the splicing combination styles.

[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
