[0021] When assembling shell cover 2 and shell 1 in actual use, only need to make several groups of plug-in seat 5 be inserted into several groups of plug-in hole 4 respectively, shell cover 2 slides from the inclined plane of limit block 7, so that limit block 7 is completely pushed into limit block installation slot 6, the movement of limit block 7 makes limit spring 8 be compressed, when rubber pad 3 is compressed on the surface of shell 1 and LED lamp panel, shell cover 2 is also closely attached to the surface of shell 1, at this time, shell cover 2 is removed from the end of limit block 7, then limit spring 8 pushes the end of limit block 7 out of limit block installation slot 6 under the action of its elasticity, the end of limit block 7 extending limit block installation slot 6 abuts on the surface of one end of shell cover 2 away from shell 1, so that the assembly of shell 1 and shell cover 2 can be realized, when LED lamp panel and other components need to be overhauled, only need to manually push each group of limit block 7 into limit block installation slot 6 completely, then make plug-in seat 5 exit from plug-in hole 4, so that the disassembly of shell 1 and shell cover 2 can be realized, which makes the disassembly of shell 1 and shell cover 2 very fast and does not need to use third-party tools, saving time and effort.
[0022] In order to keep the limit block 7 in the state of being completely retracted into the limit block mounting slot 6, a push rod slot 9 is formed on the surface of the limit block 7, a push rod hole 10 is formed on the surface of the plug-in seat 5, a push rod 11 is movably inserted into the push rod slot 9, the push rod 11 is slidingly connected in the push rod hole 10, a sleeve 14 is fixed on the surface of the plug-in seat 5, a locking rod 15 is movably inserted into the sleeve 14, a memory cotton 16 is fixed between the end of the locking rod 15 extending into the sleeve 14 and the inner wall of the sleeve 14, and the other end of the locking rod 15 abuts against the surface of the push rod 11.
[0023] When the number of limit blocks 7 is large, after a group of limit blocks 7 is completely pressed into the limit block mounting slot 6, the group of limit blocks 7 needs to be kept in this state, and the shell 1 and the shell cover 2 can be separated only when all groups of limit blocks 7 are completely pressed into the limit block mounting slot 6 and kept in this state. When a group of limit blocks 7 is completely pressed into the limit block mounting slot 6, the push rod 11 inserted into the push rod slot 9 formed on the surface of the group of limit blocks 7 moves along with the limit block 7, the group of push rods 11 slides in the push rod hole 10, the end of the group of push rods 11 is away from the push rod 11, and the memory cotton 16 in the compressed state pushes the one end of the locking rod 15 out of the sleeve 14 under the elastic force of itself, the locking rod 15 that is pushed out blocks the path of the push rod 11 returning to the original position, so that the push rod 11 cannot return to the original position, and the group of limit blocks 7 is kept in the state of being completely retracted into the limit block mounting slot 6.
[0024] In order to replace the limit spring 8, a snap ring 12 is fixed on the surface of the push rod 11, a snap slot 13 is formed on the inner wall of the push rod slot 9, and the snap slot 13 is an annular groove, and the snap ring 12 is movably inserted into the snap slot 13.
[0025] When the limit spring 8 needs to be replaced, the push rod 11 is pulled outward with force, so that the snap ring 12 is compressed and withdrawn from the snap slot 13, then the push rod 11 can be pulled out of the push rod slot 9, after being pulled out, the group of limit blocks 7 can be pulled out of the limit block mounting slot 6, then the old limit spring 8 can be poured out of the limit block mounting slot 6, the new limit spring 8 is inserted back into the limit block mounting slot 6, after being inserted back, the limit block 7 is inserted back into the limit block mounting slot 6, and the push rod 11 is inserted back into the push rod slot 9 through the push rod hole 10. When the snap ring 12 is inserted back into the snap slot 13, a large force is required to compress the snap ring 12, so that the snap ring 12 can limit the push rod 11 in the push rod slot 9 when the push rod 11 is not pulled with force, and the replacement of the limit spring 8 is completed.
[0026] In actual use, when assembling the shell cover 2 and the shell body 1, only need to insert a plurality of groups of the insertion sockets 5 into a plurality of groups of the insertion holes 4 respectively, and slide the shell cover 2 from the inclined surface of the limiting block 7, so that the limiting block 7 is completely pushed into the limiting block mounting groove 6, the movement of the limiting block 7 makes the limiting spring 8 be compressed, when the rubber pad 3 is pressed on the surface of the shell body 1 and the LED lamp panel, the shell cover 2 is also tightly attached to the surface of the shell body 1, at this time, the shell cover 2 is moved away from the end of the limiting block 7, then the limiting spring 8 pushes the end of the limiting block 7 out of the limiting block mounting groove 6 under the elastic force of itself, the end of the limiting block 7 extending out of the limiting block mounting groove 6 abuts against the end surface of the shell cover 2 away from the shell body 1, so that the assembly of the shell body 1 and the shell cover 2 is realized; when it is needed to overhaul the LED lamp panel and other components, only need to manually push each group of the limiting block 7 into the limiting block mounting groove 6 completely, and then make the insertion socket 5 exit from the insertion hole 4, so that the disassembly of the shell body 1 and the shell cover 2 is realized; this makes the disassembly of the shell body 1 and the shell cover 2 very fast and does not need to use third-party tools, which saves time and effort; when the number of the limiting block 7 is large, when disassembling the shell body 1 and the shell cover 2, after a group of the limiting block 7 is pressed into the limiting block mounting groove 6 completely, the group of the limiting block 7 needs to keep this state, and when each group of the limiting block 7 is pressed into the limiting block mounting groove 6 completely and keeps this state, the disassembly of the shell body 1 and the shell cover 2 can be realized; when a group of the limiting block 7 is pressed into the limiting block mounting groove 6 completely, the push rod 11 in the push rod slot 9 opened on the surface of the group of the limiting block 7 follows the limiting block 7 to move in a straight line, the group of the push rod 11 slides in the push rod hole 10, so that the group of the push rod 11 is away from the end of the push rod 11, then the memory cotton 16 in the compressed state pushes the end of the locking rod 15 out of the sleeve 14 under the elastic force of itself, the locking rod 15 that is pushed out blocks the path of the push rod 11 returning to the original position, so that the push rod 11 cannot return to the original position, which makes the group of the limiting block 7 keep in the state of being completely retracted into the limiting block mounting groove 6; when it is needed to replace the limiting spring 8, pull the push rod 11 outward with force, so that the clamping ring 12 is compressed and exits from the clamping slot 13, then the push rod 11 can be pulled out of the push rod slot 9, after being pulled out, the group of the limiting block 7 can be pulled out of the limiting block mounting groove 6, then the old limiting spring 8 can be poured out of the limiting block mounting groove 6, the new limiting spring 8 can be inserted back into the limiting block mounting groove 6, after being inserted back, the limiting block 7 is inserted back into the limiting block mounting groove 6, and the push rod 11 is inserted back into the push rod slot 9 through the push rod hole 10, when the clamping ring 12 is inserted back into the clamping slot 13, because a large force is needed to compress the clamping ring 12, therefore, when the push rod 11 is not pulled with force, the clamping ring 12 can limit the push rod 11 in the push rod slot 9, and the replacement of the limiting spring 8 is completed.
