DETAILED DESCRIPTION

[0030] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as a limitation of the utility model.

[0031] The utility model relates to a kind of cylinder spotlight quick installation structure, including shell 100, connecting seat 200, light projection cover 300 and lamp source assembly 400.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 And Figure 5As shown, the shell 100 can be cylindrical, or can be configured in other shapes such as a square cylinder. The connecting seat 200 is arranged in the shell 100. The connecting seat 200 can be mounted in the shell 100 as a separate component, or can be integrally formed in the shell 100. The connecting seat 200 defines a first mounting cavity 210. A plurality of elastic clamping heads 220 are arranged on the circumferential inner portion of the first mounting cavity 210. The elastic clamping heads 220 can be elastically turned outwards under the action of an external force, and the elastic clamping heads 220 can be collapsed in the center direction of the first mounting cavity 210 under the action of their own elastic force. The elastic clamping heads 220 can be one, two or more. The plurality of elastic clamping heads 220 can be uniformly distributed along the circumference of the first mounting cavity 210. The light projection cover 300 is provided with a convex edge 310 extending outward in a circular ring shape. The light source assembly 400 is mounted in the shell 100. The light source assembly 400 includes a lamp panel and a lamp bead, and can further be provided with a lens and the like. During installation, the light source assembly 400 is first mounted into the shell 100, and then the connecting seat 200 is fixed into the shell 100. Finally, when the light projection cover 300 is installed, part of the light projection cover 300 together with the convex edge 310 is inserted into the first mounting cavity 210 in a direction gradually approaching the light source assembly 400. During the insertion of the light projection cover 300, the convex edge 310 abuts against the elastic clamping heads 220, and then as the light projection cover 300 continues to be inserted, the convex edge 310 elastically pushes the elastic clamping heads 220 outwards in a direction away from the center of the first mounting cavity 210, until the convex edge 310 passes the position of the elastic clamping heads 220, and the elastic clamping heads 220 are elastically reset towards the center of the first mounting cavity 210. The reset elastic clamping heads 220 limit the light projection cover 300 from being separated from the first mounting cavity 210 in a direction away from the light source assembly 400. In this way, the light projection cover 300 can be quickly installed. After installation, the light generated by the light source assembly 400 is projected outward through the light projection cover 300. The circular ring-shaped convex edge 310 can be limited by the elastic clamping heads 220 regardless of the rotation of the light projection cover 300. The light projection cover 300 does not need to be aligned or positioned during installation, and the installation is simple and fast.

[0033] In some embodiments of the present application, as shown in Figure 2 , Figure 3 and Figure 4 , the light projection cover 300 includes a hollow cylinder portion 320. The cylinder portion 320 can be cylindrical, or can be configured in other shapes such as a square cylinder, a horn, etc. The convex edge 310 extends radially outwards from the circumferential outer wall of the cylinder portion 320. The light generated by the light source assembly 400 is projected outward through the cylinder portion 320, and the cylinder portion 320 has a light collecting effect.

[0034] Further, the two ends of the cylinder part 320 are defined as a first end 321 and a second end 322 respectively. The convex edge 310 is formed on the outer wall of the first end 321. The outer wall of the second end 322 extends out of the cover plate part 330. The cover plate part 330 can be provided in a flat plate shape or in an arc shape. The inside of the shell 100 is provided with a second mounting cavity 110. One end of the second mounting cavity 110 is open to form a projection port 120. The connecting seat 200 and the light source assembly 400 are mounted in the second mounting cavity 110. After the light projection cover 300 is connected with the connecting seat 200, the cover plate part 330 covers the projection port 120. The second mounting cavity 110 is sealed by the cover plate part 330, and the periphery of the cover plate part 330 can protrude outside the second mounting cavity 110.

[0035] In an embodiment, as shown in Figure 3 , Figure 5 and Figure 6 , the inner wall of the first mounting cavity 210 extends a lap wall 230 in the circumferential direction. The lap wall 230 is in a circular ring shape. After the light projection cover 300 is mounted in place relative to the connecting seat 200, the convex edge 310 is limited between the lap wall 230 and the elastic clamping head 220, or one side of the convex edge 310 abuts against the elastic clamping head 220 and the other side abuts against the lap wall 230, so as to fix the light projection cover 300 and avoid shaking of the light projection cover 300 in the insertion direction.

[0036] In some specific embodiments of the present application, as shown in Figure 3 and Figure 6 , the elastic clamping head 220 includes a clamping plate 221 and a clamping convex 222. A U-shaped through slot 250 is formed in the circumferential side wall of the connecting seat 200, and the position of the connecting seat 200 surrounded by the U-shaped through slot 250 constitutes the clamping plate 221. The clamping convex 222 is formed protruding from the clamping plate 221. The clamping plate 221 has a certain elastic deformation capability relative to the connecting seat 200, and can drive the clamping convex 222 to elastically swing close to or away from the center of the connecting seat 200. The clamping convex 222 protrudes in the direction of the center of the connecting seat 200. The convex edge 310 of the light projection cover 300 is clamped and limited by the clamping convex 222.

[0037] Based on the above embodiment, the first installation cavity 210 has an insertion opening 211. During installation, the light projection cover 300 is inserted into the first installation cavity 210 from the insertion opening 211. The clamping protrusion 222 has a first surface 223 and a second surface 224. The first surface 223 is arc-shaped, and the second surface 224 is planar. The first surface 223 faces the insertion opening 211, and the second surface 224 is away from the insertion opening 211. During installation, the protruding edge 310 first abuts against the first surface 223, and then slides downward along the arc surface of the first surface 223 while pushing the elastic plate 221 outward, so as to reduce the resistance of the clamping protrusion 222 to the protruding edge 310 during insertion. After the protruding edge 310 passes the clamping protrusion 222, the second surface 224 is opposite to the protruding edge 310, and the protruding edge 310 is limited from moving away from the light source assembly 400 by the second surface 224, so as to limit the light projection cover 300 in the connecting seat 200. The end portion between the first surface 223 and the second surface 224 close to the center of the first installation cavity 210 is provided with a circular arc transition surface 225. When the protruding edge 310 passes from the first surface 223 to the second surface 224, the protruding edge 310 abuts against the circular arc transition surface 225, and the circular arc transition surface 225 reduces the resistance to the protruding edge 310 during insertion.

[0038] In some embodiments of the present application, as shown in Figure 6 and Figure 7 The inner wall of the first installation cavity 210 is provided with a clamping hook 240. The clamping hook 240 can extend out from the lap wall 230 towards the light source assembly 400. The outer wall of the light source assembly 400 is provided with a clamping groove 410 extending in the circumferential direction. During installation, the light source assembly 400 is first fixed in the outer shell 100, and then the connecting seat 200 is put into the outer shell 100 from the projection opening 120. At least a part of the light source assembly 400 is inserted into the first installation cavity 210, and then the clamping hook 240 is paired and clamped in the clamping groove 410. Thus, the connecting seat 200 is fixed. After being fixed, the connecting seat 200 can also be further locked in the outer shell 100 by using a screw. The inner part of the outer shell 100 is provided with a boss 130. The boss 130 is located on the side of the second cavity away from the projection opening 120. The side of the light source assembly 400 away from the connecting seat 200 abuts against the boss 130. The boss 130 is provided with a connecting column 131, and the light source assembly 400 is connected with the connecting column 131 by a screw. Thus, the installation of the light source assembly 400 is completed.
