DETAILED DESCRIPTION

[0026] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0027] First embodiment:

[0028] See also Figure 1-4 A collision-resistant structure includes a connector 10 and a face tube 20 installed on the connector 10. The connector 10 and the face tube 20 are connected by a fastener 30. The two ends of the connector 10 are respectively provided with a first through hole 11, and the face tube 20 is provided with a second through hole 21. The face tube 20 is inserted into the connector 10, or sleeved outside the connector 10, and the first through hole 11 and the second through hole 21 are aligned. The fastener 30 includes a penetration unit 31 and a connection unit 32. The penetration unit 31 includes a rod 311 and a first limiting head 315 located at one end of the rod 311. The connection unit 32 includes a connection part 321 and a second limiting head 322 located at one end of the connection part 321. After the other end of the rod 311 penetrates the first through hole 11 and the second through hole 21, it is screwed with the other end of the connection part 321. Through the above structure, the connector 10 and the surface pipe 20 are connected in a through-connection manner through the fastener 30, thereby improving the structural strength of the protective facility, enhancing the overall impact resistance of the protective facility, and facilitating installation.

[0029] In one solution, an internal threaded hole is provided at one end of the rod portion 311 connected to the connecting portion 321, and the connecting portion 321 is a screw rod.

[0030] Second embodiment:

[0031] The difference from the first embodiment is that, see Figure 2-4A positioning portion 314 is also provided between the rod 311 and the first stop head 315. The diameter of the rod 311 is smaller than the diameter of the positioning portion 314. A transition portion 313 is provided between the rod 311 and the positioning portion 314. An end of the rod 311 connected to the connecting portion 321 is provided with an external thread 312. The connecting portion 321 is a tube body with an internal thread. Since the diameter of the rod 311 is smaller than the diameter of the positioning portion 314, the rod 311 can be easily inserted into the first through hole 11 and the second through hole 21 during installation. In a specific embodiment, the outer diameter of the connecting portion 321 is the same as the outer diameter of the positioning portion 314, so that the diameters of the first through hole 11 and the second through hole 21 are the same, which facilitates punching of the first through hole 11 and the second through hole 21.

[0032] During installation, the rod 311 is first inserted into the first through hole 11 and the second through hole 21 from bottom to top, and then the connecting portion 321 of the connecting unit 32 is screwed and fixed to the external thread 312 on the rod 311 at the top.

[0033] In order to facilitate the screwing of the penetration unit 31 and / or the connection unit 32, the first limiting head 315 and / or the second limiting head 322 are provided with an inner polygonal hole 316. Preferably, the inner polygonal hole 316 is a hexagonal hole, which is convenient for installation by a hexagonal universal wrench.

[0034] In another embodiment, see Figure 3 , 4 The first limiting head 315 is provided with an inner polygonal hole 316, and the outer wall of the connecting portion 321 is axially provided with a plurality of limiting ribs 324. Specifically, the limiting ribs 324 are edges provided on the outer wall of the connecting portion 321. When the connecting portion 321 is knocked into the first through hole 11 and the second through hole 21 on the upper side, the connecting portion 321 is limited by the limiting ribs 324 with the first through hole 11 and the second through hole 21, so as to prevent the connecting unit 32 from rotating when the penetration unit 31 is twisted.

[0035] During installation, the rod 311 is first inserted into the first through hole 11 and the second through hole 21 from bottom to top, and then the connecting portion 321 of the connecting unit 32 is screwed to the external thread 312 on the rod 311 at the top for a distance, and then the connecting unit 32 is lightly tapped to knock the connecting portion 321 into the first through hole 11 and the second through hole 21 on the upper side, and then the unit 31 is screwed through the inner polygonal hole 316 on the first stopper head 315. In this way, the top of the connecting unit 32 can be smooth and free of holes, and water and dust will not accumulate.

[0036] Furthermore, in order to facilitate the connection portion 321 of the connection unit 32 to be inserted into the first through hole 11 and the second through hole 21 on the upper side, a guide portion 323 is provided at one end of the connection portion 321 away from the second limiting head 322 .

[0037] The third embodiment:

[0038] A protective facility adopts the anti-collision structure.

[0039] For example, in CN203022252U, an anti-impact structure of the present application can be used to connect the surface pipe and the corner tee connector.
