[0029] Please refer to Figures 1 to 6 , the embodiment of the present utility model provides a portable side plate hinge mechanism for urban rail rescue ladders, which is used to form the ladder frames on both sides of the rescue ladder. A pedal 2 is installed between two sets of side plate hinge mechanisms 1 to form a foldable rescue ladder;

[0030] Specifically, the side plate hinge mechanism 1 includes an inner hinge plate 11, a middle hinge plate 12, and an outer hinge plate 13. The inner hinge plate 11 and the outer hinge plate 13 are respectively arranged on both sides of the middle hinge plate 12;

[0031] Both sides of the middle hinge plate 12 are respectively hinged to the inner hinge plate 11 and the outer hinge plate 13 through the first hinge assembly; two adjacent middle hinge plates 12 arranged vertically are hinged through the second hinge assembly, and two adjacent outer hinge plates 13 arranged vertically and two adjacent inner hinge plates 11 arranged vertically are all hinged through the third hinge assembly;

[0032] In the unfolded state, a group of inner hinge plates 11, middle hinge plates 12 and outer hinge plates 13 are arranged in a C shape to form a group of hinge modules. Each column of side plate hinge mechanisms 1 is formed by multiple groups of hinge modules distributed vertically, that is, the vertically distributed hinge modules are hinged through the second hinge assembly and the third hinge assembly; in the folded state, a group of inner hinge plates 11, middle hinge plates 12 and outer hinge plates 13 are arranged in the same plane, which is convenient for the folding and storage of the adjacent middle hinge plates 12, inner hinge plates 11 and outer hinge plates 13 vertically.

[0033] In a preferred embodiment, a plurality of first U-shaped guide sleeves 14 and second U-shaped guide sleeves 15 are symmetrically and fixedly arranged on both sides of the middle hinge plate 12, and the first U-shaped guide sleeves 14 and the second U-shaped guide sleeves 15 are arranged at uniform intervals;

[0034] Among them, the opening directions of the first U-shaped guide sleeve 14 and the second U-shaped guide sleeve 15 are respectively arranged in opposite directions on both sides of the middle hinge plate 12; that is, the opening direction of the first U-shaped guide sleeve 14 faces one side of the middle hinge plate 12, and the opening direction of the second U-shaped guide sleeve 15 faces the other side of the middle hinge plate 12;

[0035] In a preferred embodiment, a plurality of third U-shaped guide sleeves 16 and fourth U-shaped guide sleeves 17 are fixedly arranged on one side of the inner hinge plate 11 and the outer hinge plate 13, and the third U-shaped guide sleeves 16 and the fourth U-shaped guide sleeves 17 are arranged at uniform intervals; and the opening directions of the third U-shaped guide sleeve 16 and the fourth U-shaped guide sleeve 17 are the same as those of the first U-shaped guide sleeve 14 and the second U-shaped guide sleeve 17, and are respectively arranged in opposite directions on both sides of the inner hinge plate 11 or the outer hinge plate 13, which is convenient for wrapping the first rotating pin 112, and then installing and limiting between the inner hinge plate 11, the middle hinge plate 12 and the outer hinge plate 13 through the first rotating pin 112;

[0036] Among them, the installation of the third U-shaped guide sleeve 16 and the fourth U-shaped guide sleeve 17 on the inner hinge plate 11 and the outer hinge plate 13 and which specific side they are installed on are set according to the actual use and installation situation.

[0037] In a preferred embodiment, one side of the inner hinge plate 11 and the outer hinge plate 13 are respectively butted against both sides of the middle hinge plate 12. After butt-joint, the first U-shaped guide sleeve 14, the third U-shaped guide sleeve 16, the second U-shaped guide sleeve 15, and the fourth U-shaped guide sleeve 17 located in the same column are arranged at intervals in sequence; the first hinge assembly includes a first rotating pin 112, and the first rotating pin 112 is sequentially arranged inside the first U-shaped guide sleeve 14, the third U-shaped guide sleeve 16, the second U-shaped guide sleeve 15, and the fourth U-shaped guide sleeve 17 located in the same column, which is used to realize the function that the inner hinge plate 11 and the outer hinge plate 13 rotate relative to the middle hinge plate 12. Furthermore, in the unfolded state, it is arranged in a C shape.

[0038] At one end of the middle hinge plate 12, two parallel first hinge lugs 18 are fixedly arranged, and at the other end, three parallel second hinge lugs 19 are fixedly arranged; the first hinge lugs 18 and the second hinge lugs 19 are respectively arranged on both side surfaces of the plate surface of the middle hinge plate 12, which is convenient for the butt-joint connection between two adjacent middle hinge plates 12 up and down. Since the first hinge lugs 18 and the second hinge lugs 19 at both ends of the middle hinge plate 12 are respectively arranged on both sides of the plate surface of the middle hinge plate 12, the butt-joint between two adjacent middle hinge plates 12 up and down is achieved by connecting the first hinge lug 18 of one middle hinge plate 12 with the second hinge plate 19 on its adjacent middle hinge plate 12. In this way, the middle hinge plate 12 can continuously realize the folding function, and the two middle hinge plates 12 on both sides of one middle hinge plate 12 can be folded towards both sides of this middle hinge plate 12 in the middle.

[0039] Specifically, two adjacent middle hinge plates 12 are arranged one above the other. The two first hinge lugs 18 on one middle hinge plate 12 are arranged between the three second hinge lugs 19 on its adjacent middle hinge plate 12; the second hinge assembly includes a second rotating pin 113, and the second rotating pin 113 is sequentially rotatably arranged through the plate surfaces of the first hinge lug 18 and the second hinge lug 19, which is used to realize the installation limit and folding functions of the middle hinge plates 12 arranged one above the other.

[0040] At one end of the inner hinge plate 11 and the outer hinge plate 13, a third hinge lug 110 is fixedly arranged, and at the other end, fourth hinge lugs 111 are symmetrically and fixedly arranged; moreover, the third hinge lug 110 and the fourth hinge lugs 111 are respectively arranged on both side surfaces of the inner hinge plate 11 and the outer hinge plate 13;

[0041] Since the inner hinge plates 11 and the outer hinge plates 13 are both provided with the third U-shaped guide sleeves 16 and the fourth U-shaped guide sleeves 17 only on one side, the directions of the third hinge lugs 110 and the fourth hinge lugs 111 of the vertically arranged inner hinge plates 11 are opposite, so as to ensure that the vertically arranged inner hinge plates 11 are folded in sequence, and the same applies to the outer hinge plates 13.

[0042] In a preferred embodiment, two adjacent inner hinge plates 11 and two adjacent outer hinge plates 13 are both arranged vertically; the third hinge lug 110 on one inner hinge plate 11 is arranged to pass through between the two fourth hinge lugs 111 on its adjacent inner hinge plate 11; the third hinge lug 110 on one outer hinge plate 13 is arranged to pass through between the two fourth hinge lugs 111 on its adjacent outer hinge plate 13; the third hinge assembly includes a third rotating pin 114, and the third rotating pin 114 is sequentially rotatably arranged through the plate surfaces of the corresponding third hinge lug 110 and the fourth hinge lug 111, so as to realize the installation limit and folding functions between two vertically adjacent inner hinge plates 11 and two vertically adjacent outer hinge plates 13.

[0043] Among them, through holes are provided on the first hinge lug 18, the second hinge lug 19, the third hinge lug 110 and the fourth hinge lug 111 for the first rotating pin 112, the second rotating pin 113 and the third rotating pin 114 to pass through, so as to realize the docking, installation, limit and rotation between the vertically adjacent inner hinge plates 11, the middle hinge plates 12 and the outer hinge plates 13.

[0044] The working principle of the present utility model:

[0045] The side plate hinge mechanism 1 exists in a columnar shape. The pedals 2 are uniformly fixedly installed between the two columns of side plate hinge mechanisms 1, so as to form a foldable rescue ladder; the two columns of side plate hinge mechanisms 1 are symmetrically structured with the middle pedal 2 as the center. Each column of side plate hinge mechanisms 1 includes vertically distributed inner hinge plates 11, middle hinge plates 12 and outer hinge plates 13. Among them, both ends of the vertically distributed middle hinge plates 12 are connected by hinge joints through the second rotating pins 113. The vertically distributed outer hinge plates 13 and the vertically distributed inner hinge plates 11 are both connected by hinge joints through the third rotating pins 114, and the rotation directions are the same as those of the middle hinge plates 12 in the same horizontal direction;

[0046] The inner hinge plates 11 and the outer hinge plates 13 on both sides of the middle hinge plates 12 are both connected by hinge joints through the first rotating pins 112;

[0047] Since the installation directions of the first hinge ear plates 18, the second hinge ear plates 19, the third hinge ear plates 110, and the fourth hinge ear plates 111 at both ends of the middle hinge plate 12, the inner hinge plate 11, and the outer hinge plate 13 are opposite, the rotation directions of the middle hinge plate 12, the inner hinge plate 11, and the outer hinge plate 13 can be opposite. And after the inner hinge plate 11 and the outer hinge plate 13 rotate towards the middle hinge plate 12, a C-shaped ladder frame is formed to bear the weight as the ladder body, improving the load-bearing capacity and reliability. The first hinge ear plates 18, the second hinge ear plates 19, the third hinge ear plates 110, and the fourth hinge ear plates 111 support and limit each other, ensuring the stability of the support structure in the unfolded state of the side plate hinge mechanism 1, improving the safety performance and extending the service life.

[0048] When in use, by flattening the "C"-shaped ladder frame in the side plate hinge mechanism 1, the inner hinge plates 11, the middle hinge plate 12, and the outer hinge plates 13 are merged in sequence, realizing the rapid folding of the urban rail rescue ladder. And through the reverse design of the hinge joints (i.e., the first hinge ear plates 18, the second hinge ear plates 19, the third hinge ear plates 110, and the fourth hinge ear plates 111) at both ends of the inner hinge plate 11, the middle hinge plate 12, and the outer hinge plate 13, the side plate hinge mechanism 1 does not interfere with each other after being merged in sequence, improving the folding reliability and reducing the occupied space.
