[0020] Please refer to Figures 1-2 Protection assembly 7 includes fixed plate 71 fixedly installed on the top of mounting block 3 in symmetrical distribution, gear 72 is fixedly sleeved on the outer surface of the top end of rotating shaft 4, two sliding grooves 73 are symmetrically arranged on the top of mounting block 3, sliding block 74 is slidably installed in two sliding grooves 73, rack 75 is fixedly installed on the top of sliding block 74, the opposite sides of rack 75 are engaged with the outer surface of gear 72, first spring 76 is fixedly installed on the opposite side of fixed plate 71, one end of first spring 76 away from fixed plate 71 is fixedly connected with one end of rack 75, the bottom of rack 75 is slidably connected with the top of mounting block 3.
[0021] Please refer to Figure 1 And Figure 4The barrier bar 6 includes a connecting block 61 that can be detachably inserted into one end of the rotating block 5. A hollow rod 62 is fixedly installed at one end of the connecting block 61. Slots 63 are evenly opened on the outer surface of the hollow rod 62. A round rod 64 is inserted into the hollow rod 62. An installation groove 65 is opened on the outer surface of the end of the round rod 64 located inside the hollow rod 62. A second spring 66 is fixedly installed at the bottom inside the installation groove 65. A protrusion 67 is fixedly installed at the top of the second spring 66. The protrusion 67 can slide in the installation groove 65 and is inserted into the slot 63. A support block can be provided at the end of the round rod 64 to support the round rod 64 and prevent the end of the round rod 64 from sagging due to excessive gravity.
[0022] Please see Figure 4 Insert rods 8 are inserted into the top and one side of the rotating block 5. The insert rods 8 pass through the rotating block 5 and the connecting block 61. A nut 9 is threaded onto the outer surface of one end of the insert rod 8. The insert rods 8 and the nut 9 facilitate the disassembly and replacement of the barrier bar 6. During installation, the connecting block 61 is inserted into the rotating block 5. Then, the two insert rods 8 are inserted vertically and horizontally into the rotating block 5, so that the insert rods 8 pass through the rotating block 5 and the connecting block 61. Finally, the nut 9 is screwed onto the other end of the insert rod 8.
[0023] Working principle: In use, the barrier bar 6 is first installed on the rotating block 5 using the insert rod 8 and nut 9. When the barrier bar 6 is impacted, it will rotate, thereby driving the rotating shaft 4 to rotate as well, which in turn drives the gear 72 to rotate. Since the opposite sides of the two racks 75 are engaged with the outer surface of the gear 72, when the gear 72 rotates, it will drive the two racks 75 to move synchronously in opposite directions, thereby driving the slider 74 to slide in the groove 73. When the two racks 75 move, they will stretch and compress the first springs 76 set at their respective ends. At this time, the barrier bar 6 is in an inclined state, and the rebound force generated by the first spring 76 will push the racks 75 to move back, thereby driving the gear 72 to rotate in the opposite direction, and thus driving the barrier bar 6 to return to its initial state, thereby preventing the barrier bar 6 from bending and being damaged by impact.
[0024] When the length of the barrier bar 6 needs to be adjusted, first press the protrusion 67 with your finger. At this time, the protrusion 67 retracts into the mounting groove 65 and presses down on the second spring 66. Then, the round rod 64 can be pulled out from the hollow rod 62 until the appropriate length is achieved. Finally, the rebound force of the second spring 66 is used to push the protrusion 67 upward in the mounting groove 65, so that the protrusion 67 is inserted into the slot 63, thereby fixing the round rod 64. The reverse is also true.
