[0041] A guardrail cross pipe 11 is hinged between the active rotating arm 2 and the auxiliary rotating arm 1 , and the active rotating arm 2 and the auxiliary rotating arm 1 are respectively rotated and tilted to one side along the rotating assembly 6 .

[0042] As a preferred embodiment, the two fixed connecting frames 8 are arranged in parallel, and a fixed U-shaped frame 9 is provided at the front end of each fixed connecting frame 8 to be fixedly connected to the bed frame. This structure can facilitate the installation of the guardrail and the bed frame.

[0043] In order to facilitate the tipping of the guardrail, the active rotating arm 2 is in a U-shaped structure, and the auxiliary rotating arm 1 is in an L-shaped structure.

[0044] The rotating assembly 6 includes a rotating shaft 601, and an auxiliary support plate 17 is also installed in the fixed connecting frame 8; the auxiliary support plate 17 is used to support the rotating shaft 601, one end of the rotating shaft 601 cooperates with the second limiting slide plate 5 through a shaft sleeve 602, and extends to be connected to the lower end of the auxiliary rotating arm 1, and the other end cooperates with the auxiliary support plate 17 through a shaft sleeve 602, and extends to the other side of the auxiliary support plate 17, on which a spring 604 is sleeved, and flat washers 603 are respectively provided at both ends of the spring 604, and this shaft end is also locked by a locking nut 605. The rotating assembly 6 facilitates the rotation of the auxiliary rotating arm 1 and the active rotating arm 2.

[0045] Furthermore, the rotating shaft 601 is interference fit with the shaft hole of the auxiliary rotating arm 1 .

[0046] The locking mechanism 7 includes an unlocking wrench 701 and a locking sleeve 704, the locking sleeve 704 passes through the rotating plate 705, the unlocking wrench 701 cooperates with the locking sleeve 704, and an unlocking pin 702 is provided in the locking sleeve 704, the unlocking pin 702 extends out of the locking sleeve 704 and is connected to the unlocking wrench 701, an unlocking compression spring 703 is sleeved on the unlocking pin 702, and the unlocking compression spring is provided between the shaft shoulder and the end wall of the locking sleeve 704; the shaft end of the unlocking pin 702 is connected to the unlocking wrench 701 through a countersunk screw.

[0047] To facilitate the installation of the guardrail cross tube 11, the inner side of the auxiliary rotating arm 1 is welded with mounting plates B16 and A15 from top to bottom, and the inner side of the active rotating arm 2 is welded with mounting plates A15 and B16 from top to bottom corresponding to the auxiliary rotating arm 1; the two ends of the guardrail cross tube 11 are respectively connected with a connecting shaft A12, and the two ends of the guardrail cross tube 11 are respectively connected to the corresponding mounting plates A15 and B16 through the connecting shaft A12; the upper ends of the auxiliary rotating arm 1 and the active rotating arm 2 are both connected with a connecting shaft B13, and the guardrail cross tube 11 is hinged with the connecting shaft B13 through the connecting shaft A12. With this structure, the guardrail cross tube 11 can be hinged with the auxiliary rotating arm 1 and the active rotating arm 2, which is convenient for the tipping of the auxiliary rotating arm 1 and the active rotating arm 2.

[0048] To facilitate the connection between the connecting shaft A12 and the connecting shaft B13, the end of the connecting shaft A12 is a two-shaped structure, and the end of the connecting shaft B13 is a one-shaped structure. The connecting shaft A12 and the connecting shaft B13 cooperate and are connected with screws.

[0049] The sliding plate 3 is connected to the arc-shaped slideway of the second limiting slide plate 5 through an auxiliary pin 4 .

[0050] The installation process is as follows: Figure 3 As shown, the auxiliary pin 4 is placed on the arc-shaped slideway of the second limiting slide plate 5, and then Figure 1 and Figure 2 As shown, the shaft sleeve 602 of the rotating assembly 6 is respectively inserted into the second limiting slide plate 5 and the auxiliary support plate 17, and then the rotating shaft 601 of the rotating assembly 6 is passed through the second limiting slide plate 5 and the auxiliary support plate 17, and then the flat washer 603 and the spring 604, and the flat washer 603 are respectively inserted into the thread end of the rotating shaft 601 (that is, the rotating shaft 601 is inserted into the interior of the fixed connecting frame 8), and then the nut is used to lock the end thread of the rotating shaft 601; similarly, the installation method of the active rotating arm 2 is the same as the installation method of the auxiliary rotating arm 1; then as shown in FIG. Fig. 9 As shown, connecting shafts A12 are respectively inserted into both ends of the guardrail cross tube 11, and are fixed to the guardrail cross tube 11 by cross slot pan head self-tapping screws, and then the connecting shaft B13 is fixed to the auxiliary rotating arm and the active rotating arm by cross slot pan head self-tapping screws, wherein nylon bushings 14 are installed on both sides of the connecting shaft B13, and then the connecting shafts A12 at both ends of the guardrail cross tube 11 are connected to the connecting shaft B13 by hexagon socket head screws, thereby realizing articulation.

[0051] When installing the locking mechanism 7, Figure 6-Figure 8 As shown, the unlocking wrench 701 is sleeved on the locking sleeve 704, and the unlocking compression spring 703 is sleeved on the unlocking pin 702 and inserted into the locking sleeve 704, and the unlocking pin 702 is connected and fixed to the unlocking wrench 701 with a cross recessed countersunk screw;

[0052] After the guardrail is assembled, the fixed U-shaped frame 9 is buckled on the large side of the upper frame, and fixed to the large side of the upper frame with an outer hexagonal bolt, and locked and fixed with a locking nut 605.

[0053] When in use, the guardrail is lifted upward, and the unlocking assembly (unlocking wrench 701, unlocking pin 702, unlocking compression spring 703) moves upward with the guardrail. During the upward movement, the unlocking pin 702 touches the first limiting slide plate 10, and the unlocking pin 702 moves upward with the unlocking wrench 701. Figure 8 The unlocking compression spring 703 in the locking mechanism is in a compressed state (eg Figure 7 ), as shown Figure 13-14 As shown, when the locking mechanism 7 (unlocking wrench 701, unlocking pin 702, unlocking compression spring 703) moves with the guardrail to the limiting hole of the first limiting slide plate 10, under the action of the elastic force of the unlocking compression spring 703, the unlocking pin 702 bounces into the fixing hole of the first limiting slide plate. At this time, the guardrail can no longer be pulled up, and the locking is completed. At this time, the auxiliary pin 4 has also reached the limit position in the auxiliary slideway, and the guardrail can no longer be pulled up. Under this double insurance condition, the guardrail locking is more secure and reliable. When the guardrail needs to be unlocked, as shown in FIG. Figure 7 Pull the unlocking wrench 701 outward as shown, and lower the guardrail in the direction of the arrow. Figure 15-16 As shown, the unlocking pin 702 is disengaged from the limiting hole, and the guardrail is unlocked at this time. When the guardrail is lowered to the lowest position, the auxiliary pin 4 also reaches the limit position in the auxiliary slideway, limiting the guardrail from moving downward.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
