[0031] Embodiment 2

[0032] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0033] In order to enable the protection component 2 to achieve the function of stable protection, it is necessary to ensure that the protection component 2 is stably connected to the column 1. This embodiment provides the following design:

[0034] The assembly component 4 includes an assembly block 41 and an assembly tube 42. The assembly block 41 is fixedly arranged inside the column 1. The top and bottom of the assembly block 41 are provided with fixing blocks. Both sides of the assembly block 41 are provided with assembly tubes 42. The assembly tubes 42 are provided inside with mounting grooves. The mounting grooves are engaged and connected with the upper cross bar 22 and the lower cross bar 23. The assembly tubes 42 provided at both ends of the assembly block 41 can ensure that the upper cross bar 22 and the lower cross bar 23 are fixedly inserted into the column 1.

[0035] In this embodiment, the assembly component 4 also includes a reinforcement tube 43 and a baffle 44. The reinforcement tube 43 is arranged on the outside of the upper cross bar 22 and the lower cross bar 23, and the baffle 44 is arranged on the outside of the column 1. The baffle 44 is an arc-shaped structure. The baffle can prevent rainwater from entering the connection between the column 1 and the upper cross bar 22 and the lower cross bar 23, and avoid the situation where the outer protective layer of the upper cross bar 22 and the lower cross bar 23 is worn and rusted by contact with rainwater. The baffle 44 is located above the reinforcement tube 43. The reinforcement tube 43 is threadedly connected to the upper cross bar 22 and the lower cross bar 23. The end of the reinforcement tube 43 is provided with an inclined reinforcement surface, and the end of the assembly tube 42 is provided with an inclined surface corresponding to the reinforcement tube 43. The inclined reinforcement surface is slidably connected with the inclined surface, and the reinforcement tube 43 threadedly connected with the upper cross bar 22 and the lower cross bar 23 can contact with the reinforcement tube 43 under the action of rotation. At this time, the inclined reinforcement surface is slidably contacted with the inclined surface, and the reinforcement tube 43 will be fixed inside the column 1 under the action of expansion, thereby improving the firmness of the connection between the upper cross bar 22 and the lower cross bar 23 and the column 1. At the same time, after the railing is used for a long time, the combination effect of the upper cross bar 22 and the lower cross bar 23 can be stabilized by rotating the reinforcement tube 43. In this way, the upper cross bar 22 and the lower cross bar 23 can be reduced. After being loosened, the continuous collision and damage with the column 1 can be reduced;

[0036] The implementation principle of the second embodiment is as follows: when the protection component 2 is connected to the column 1, the upper cross bar 22 and the lower cross bar 23 are inserted into the mounting groove inside the assembly tube 42. At this time, the reinforcing tube 43 is rotated, and the reinforcing tube 43 threadedly connected with the upper cross bar 22 and the lower cross bar 23 will contact the reinforcing tube 43 under the action of rotation, and the inclined reinforcing surface will slide in contact with the inclined surface, and the reinforcing tube 43 will expand outward, and the expanded reinforcing tube 43 will further engage with the column 1, so that the firmness of the connection between the upper cross bar 22 and the lower cross bar 23 and the column 1 can be improved;

[0037] When the guard assembly 2 is not firmly connected after the railing has been used for a long time, the reinforcing tube 43 can be rotated to improve the clamping effect of the reinforcing tube 43 and the column 1, thereby stabilizing the upper cross bar 22 and the lower cross bar 23 connected to the column 1, thereby reducing the upper cross bar 22 and the lower cross bar 23 from being continuously damaged by collision with the column 1 after they become loose.
