Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

As shown in Figure 1-7, the guardrail quick assembly and disassembly device based on elastic clips includes a bayonet 1, a column 2, a cross bar 3, an elastic clip 4 and a special tool 5, and the bayonet 1 includes a peripheral 1- 1. Inclined boss 1-2 and L-shaped bending structure 1-3, two L-shaped bending structures 1-3 are symmetrically arranged on the upper and lower sides of the outer periphery 1-1, which are used to limit the insertion of the cross bar 3 Depth, there is a notch in the middle of the L-shaped bending structure 1-3, an inclined boss 1-2 is provided between the notch and the periphery 1-1, and the bayonet 1 passes through the inclined boss 1- 2 and the card slot formed by the periphery 1-1 are fastened on the inside of the column 2 with the notch, and the elastic clip 4 includes an upper clip 4-1, a lower clip 4-2 and a spring 4-3. The upper clip 4-1 includes a boss 4-4, a base 4-5 and a cylindrical end 4-6, the boss 4-4 is arranged on one side of the base 4-5, and the cylindrical end 4-6 is arranged on On the other side of the base body 4-5, the boss 4-4 includes a large slope and a small chute, the small chute is set in the middle of the large slope, and the structure of the lower clip 4-2 is the same as that of the upper clip 4. -1 is the same, and the upper clamp 4-1 and the lower clamp 4-2 are connected together by the spring 4-3 through the cylindrical end 4-6; the ports on the upper and lower sides of the cross bar 3 are provided with notches , and the cross bar 3 is connected to the bayonet 1 through the elastic clip 4, the special tool 5 includes a U-shaped member 5-1 and a bar-shaped member 5-2, and the bar-shaped member 5-2 is in the U-shaped Both ends of the component 5-1 are vertically connected to the U-shaped component, and the special tool 5 is sleeved on the cross bar through the U-shaped component 5-1.

Preferably, the bayonet 1 is a plastic bayonet.

Preferably, the notch on the bayonet 1 and the notch on the cross bar 3 correspond in size to the boss 4 - 4 on the elastic clip 4 .

The installation and disassembly process of the present invention is as follows:

Assemble the upper clip 4-1, the lower clip 4-2 and the spring 4-3 into an elastic clip 4, and the spring 4-3 is connected to the cylindrical end 4-1 of the upper clip 4-1 and the lower clip 4-2 6, make the upper clamping part 4-1 and the lower clamping part 4-2 be subjected to upward and downward forces respectively. When the elastic clamp is installed on the cross bar, press the upper clamp 4-1 and the lower clamp 4-2, and then snap into the notch on the cross bar 3, as shown in FIG. 6 . When inserting the cross bar 3 and the elastic clip 4 into the column 2 installed with the bayonet 1, the large slope of the boss of the upper clip 4-1 and the lower clip 4-2 is squeezed by the bayonet, and at this time the elastic clip Under the upward and downward symmetrical force, the spring 4-3 is further compressed until the bosses of the upper clamp 4-1 and the lower clamp 4-2 just completely enter the notch of the bayonet 1, and the spring 4-3 returns to its original state at this time , so that the elastic clip 4 is stuck on the bayonet 1 to realize the connection between the cross bar 3 and the column 2 .

When the cross bar 3 needs to be pulled out, a special tool 5 needs to be used.
