[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Reference Figure 1-3 A metal shell for an LED light strip, comprising an LED light strip 4 and a shell 1, wherein the shell 1 has a bottom opening for accommodating a cavity 102 of the LED light strip 4, and a plurality of positioning grooves 401 are provided at both ends of the LED light strip 4, wherein corresponding positioning blocks 7 are inserted in the positioning grooves 401, and opposite sides of the positioning blocks 7 are provided with elastic movable components for realizing left and right movement of the positioning blocks 7, wherein the positioning blocks 7 and the elastic movable components at one end of the positioning blocks are designed in the shell 1, and corresponding positioning blocks 7 are designed on the LED light strip 4 to meet the insertion requirements of the positioning blocks 7. When the LED light bar 4 is inserted into the housing 1, the positioning block 7 is squeezed into the slot 104 by the LED light bar 4. When the positioning groove 401 of the LED light bar 4 is aligned with the positioning block 7, the positioning block 7 is reset and inserted into the positioning groove 401 by the rebound force of the elastic movable component. Therefore, when the LED light bar 4 is inserted, the overall self-locking operation can be realized, and the installation is more convenient. When disassembling, the elastic part can be pulled outward to remove the positioning block 7 from the positioning groove 401, so that the installation and disassembly operation can be realized without using tools.

[0024] Furthermore, a waterproof sealing strip 103 is embedded in the lower inner wall of the outer shell 1. When the LED light strip 4 is placed in the accommodating cavity 102, the waterproof sealing strip 103 is interference fit on the outer end of the LED light strip 4. A corresponding waterproof sealing strip 103 is arranged in the outer shell 1, which can ensure the overall waterproof performance after installation, and the waterproof performance can reach IPx8 level.

[0025] The waterproof sealing strip 103 is made of rubber or silicone.

[0026] Furthermore, reinforcing ribs 101 are formed at both ends of the shell 1 by stamping. Multiple reinforcing ribs 101 are stamped on the shell 1, which can ensure the overall strength of the shell 1 and prevent deformation. In addition, the protruding ribs can also be used as auxiliary heat dissipation fins to improve the heat dissipation effect of the LED light strip 4 when in use.

[0027] Furthermore, the entire housing 1 is made of aluminum alloy material, which has strong corrosion resistance and good strength, and the cost is relatively low while ensuring the overall service life.

[0028] Furthermore, the positioning block 7 is trapezoidal as a whole, and the upper ends of the LED light strip 4 are provided with bevels identical to the bevels of the positioning block 7. The designed bevels and the bevels of the positioning block 7 can press the positioning block 7 into the slot 104 when the LED light strip 4 is subsequently pushed into the housing 1.

[0029] Furthermore, the elastic movable component includes a movable rod 5 and a spring 6. One end of the movable rod 5 is connected to the positioning block 7. A groove 104 for accommodating the positioning block 7 is provided on the inner wall of the outer shell 1. Positioning sleeves 2 are provided at both ends of the outer shell 1 corresponding to the movable rod 5. The inner wall of the positioning sleeve 2 is provided with a through hole that meets the movement of the movable rod 5. The outer end of the movable rod 5 is integrally protruded with a blocking surface. The movable rod 5 is sleeved with a spring 6. The spring 6 is accommodated in the space between the positioning sleeve 2 and the blocking surface. When the movable rod 5 is not under force, the spring 6 can drive the movable rod 5 to reset through the rebound force of the spring 6, and the positioning block 7 is moved out of the positioning groove 4.

[0030] Furthermore, one end of the movable rod 5 extends out of the positioning sleeve 2 and is connected to a handle 3. The handle 3 can be used to pull the movable rod 5 outward when the LED light strip 4 is disassembled, so that the LED light strip 4 can be easily taken out of the housing 1.
