[0024] Now, the present application will be further described in detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic views, which only illustrate the basic structure of the present application in a schematic manner, so they only show the components related to the present application.

[0025] As Figures 1-5 shown, a circular arc visual trailer includes a vehicle body 1 and a vertical ladder. A hinge seat is provided on the side wall of the vehicle body 1. A hinge arm 3 is hinged on the hinge seat. One end of the hinge arm 3 away from the hinge seat is hinged to the horizontal tread bar 21 of the vertical ladder; a support part for supporting the hinge arm 3 to maintain a horizontal state is provided on the hinge seat.

[0026] The vertical ladder includes two vertical beams 20 arranged at intervals, and a plurality of horizontal tread bars 21 are arranged at intervals between the two vertical beams 20 along the length direction of the vertical beams 20.

[0027] The hinge seat includes a fixed plate, a support plate 103 and two hinge plates 102 arranged at intervals. The fixed plate is vertically fixed on the side wall of the vehicle body 1. The support plate 103 is horizontally arranged. The support plate 103 is connected to the lower end of the fixed plate. The two hinge plates 102 are arranged on the left and right sides of the support plate 103 and the fixed plate, and are simultaneously connected to the support plate 103 and the fixed plate.

[0028] Preferably, the whole hinge seat is integrally provided.

[0029] There is a hinge shaft between two hinged plates 102. One end of the hinge arm 3 is hingedly arranged on the hinge shaft, so that the hinge arm 3 can rotate in the hinge seat. The other end of the hinge arm 3 is rotatably connected to the horizontal tread bar 21 of the vertical ladder.

[0030] The supporting part is specifically arranged on the support plate 103 so that the hinge arm 3 can be supported by the supporting part. The supporting part can be a protrusion.

[0031] Under the action of the hinge arm 3 and the hinge seat, the entire vertical ladder can rise or fall relative to the vehicle body 1. During the descending process, the vertical ladder gradually moves away from the vehicle body 1, so that there is enough space on the horizontal tread bar 21 for people to climb when the hinge arm 3 is horizontal. During the ascending process, the vertical ladder gradually approaches the vehicle body 1 until it completely adheres to the side wall of the vehicle body 1. At this time, the horizontal tread bar 21 almost fits the side wall of the vehicle body 1 to prevent other people from climbing privately without permission and avoid potential safety hazards.

[0032] In some further embodiments, any horizontal tread bar 21 corresponds to two groups of hinge seats and hinge arms 3; the two groups of hinge seats and hinge arms 3 are arranged at intervals along the length direction of the horizontal tread bar 21.

[0033] Any horizontal tread bar 21 is correspondingly provided with two groups of hinge seats and hinge arms 3, thus ensuring the stability of the vertical ladder during the up and down movement process and also guaranteeing the load-bearing performance of the vertical ladder.

[0034] In some further embodiments, there are several groups of clamping grooves 100 corresponding to the vertical beams 20 of the vertical ladder on the side wall of the vehicle body 1, and the side walls of the clamping grooves 100 are elastically arranged.

[0035] The clamping groove 100 is formed by two rubber plates 101 arranged at intervals. The rubber plates 101 can be arranged on the side wall of the vehicle body 1 by screws or bonding.

[0036] In some further embodiments, there is a first installation groove 10 on the side wall of the vehicle body 1, and the hinge seat and the clamping groove 100 are both arranged in the first installation groove 10.

[0037] Arranging the hinge seat and the clamping groove 100 in the first installation groove 10 can ensure that the vertical ladder can be partially recessed into the interior of the side wall of the vehicle body 1 to a certain extent when it adheres to the vehicle body 1, thereby reducing the occupied space of the vertical ladder.

[0038] In some further embodiments, the vertical beam 20 is provided with a clamping hole 200, the side wall of the first installation groove 10 is provided with a sliding hole 51, the interior of the vehicle body 1 is provided with a sliding groove 50, the sliding groove 50 communicates with the sliding hole 51, a sliding rod 54 is arranged in the sliding hole 51, one end of the sliding rod 54 located in the sliding groove 50 is provided with a sliding handle 52, and the end of the sliding handle 52 away from the sliding rod 54 passes through the sliding groove 50 and is located inside the vehicle body 1; a spring 53 is arranged inside the sliding groove 50, one end of the spring 53 abuts against the side wall of the sliding handle 52 facing away from the sliding rod 54, and the other end abuts against the side wall of the sliding groove 50.

[0039] To further ensure the stability of the vertical ladder when it is in a state of being attached to the side wall of the vehicle body 1, a sliding groove 50 and a sliding hole 51 are provided on the vehicle body 1. At the same time, a sliding rod 54 is slidably arranged inside the sliding groove 50. The sliding rod 54 can be controlled by the sliding handle 52 arranged thereon, so that one end of the sliding rod 54 slides out of the sliding hole 51 and enters the area of the first installation groove 10 to insert into the clamping hole 200 on the vertical beam 20, thereby locking the vertical ladder and further ensuring the stability of its storage state. At the same time, since the sliding handle 52 is located inside the vehicle body 1, it can also prevent others from maliciously opening the vertical ladder, thereby increasing the safety guarantee of the entire vehicle body 1.

[0040] A handrail ring 11 is correspondingly arranged at the top of the vehicle body 1 to facilitate personnel to hold when climbing to the roof of the vehicle.
