DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a folding bridge for municipal construction, comprising:

[0026] A first main board 1 and a second main board 2 hingedly connected to one side of the first main board 1;

[0027] Side panels 3 are hingedly connected to the first main board 1 and the second main board 2 on opposite sides;

[0028] Two slots 4 are provided on one side of the first main board 1, and a stopper 5 for fixing the second board to the first main board 1 is provided on one side of the second main board 2;

[0029] The limiting member 5 includes two grooves 51 opened in the second main board 2, and an insert rod 52 is slidably installed inside the two grooves 51. The surface of the insert rod 52 is slidably installed inside the slot 4, and a push block 53 is fixedly installed on the surface of the insert rod 52. One end of the push block 53 passes through the inner wall of the groove 51 and extends. A limiting screw 54 is slidably installed inside the push block 53. Fixed seats 55 are provided on both sides of the limiting screw 54. The two fixing seats 55 are fixedly installed on the surface of the second main board 2, and a threaded hole 56 threadedly installed with the surface of the limiting screw 54 is opened inside the fixing seat 55.

[0030] Two adjusting nuts 6 are fixedly mounted on the surface of the limiting screw 54;

[0031] The first and second main boards 1, 2 and 3 are placed flat on the second main board 2 and the second and third side boards 3. The push block 53 is moved to drive the insertion rod 52 to slide in the groove body 51, so that one end of the insertion rod 52 passes through the second main board 2 and is inserted into the slot 4 on the surface of the first main board 1. The limiting screw 54 inside the push block 53 is rotated to make the surface of the limiting screw 54 and the threaded hole 56 inside the fixing seat 55 be installed with internal threads, thereby limiting the push block 53 and allowing the insertion rod 52 to enter the slot 4, so that the first and second main boards 1 and 2 are in the same plane to avoid folding and use. When the limiting screw 54 in the push block 53 is installed with the internal threads of the fixing seat 55 away from the side of the first main board 1, the insertion rod 52 is limited in the groove body 51 to avoid the insertion rod 52 from shaking. This is used when the folding bridge is stored. An adjusting nut 6 is provided to facilitate the rotation adjustment of the limiting screw 54.

[0032] The surfaces of the first main board 1 and the second main board 2 are both provided with grooves 7, and a resisting block 8 is slidably installed inside the two grooves 7. A resisting groove 9 for inserting the resisting block 8 is provided on one side of the side board 3.

[0033] Specifically, when the abutment block 8 in the groove 7 slides into the abutment groove 9 inside the side plate 3, the abutment block 8 is located between the abutment groove 9 and the groove 7, thereby limiting the side plate 3 and preventing the two side plates 3 from folding.

[0034] Two thread grooves 10 are formed inside the groove 7, and a conflict bolt 11 is slidably installed inside the conflict block 8, and the insides of the two thread grooves 10 are adapted to the surfaces of the conflict bolt 11;

[0035] Among them, a resistance bolt 11 is slidably installed in the resistance block 8. When the resistance bolt 11 is threadedly installed with the thread groove 10 near the inside of the groove 7, the resistance block 8 is limited in the groove 7 to prevent it from sliding and running around. When the resistance bolt 11 is threadedly installed with the thread groove 10 near the outside of the groove 7, a part of the surface of the resistance block 8 is located in the resistance groove 9, thereby preventing the side plate 3 from rotating and adjusting.

[0036] The top and bottom of the abutment block 8 are both provided with guide grooves 12, and the top and bottom of the groove 7 are both provided with guide strips 13 adapted to the guide grooves 12;

[0037] Specifically, the guide groove 12 on the surface of the abutment block 8 is matched with the guide strip 13 in the groove 7, which guides the sliding of the abutment block 8 and prevents it from falling off.

[0038] A mounting plate 14 with a hole is fixedly mounted on the top of the two side plates 3, and the two mounting plates 14 are connected by a connecting piece 15;

[0039] The mounting plates 14 on the surfaces of the two side plates 3 are used to fix the device after it is folded.

[0040] The connecting member 15 includes a mounting bolt 151 penetrating through the inner holes of the two mounting plates 14, and a mounting nut 152 is threadedly mounted on the surface of the mounting bolt 151;

[0041] Furthermore, by passing the mounting bolts 151 through the holes in the two mounting plates 14 and threadedly mounting the mounting nuts 152, the folding can be limited in position and cannot be unfolded, thus facilitating transportation operations.

[0042] The device unfolds the first main board 1, the second main board 2 and the two side boards 3 and lays them flat, and moves the push block 53 to drive the insertion rod 52 to slide in the groove body 51, so that one end of the insertion rod 52 passes through the second main board 2 and is inserted into the slot 4 on the surface of the first main board 1, and the limiting screw 54 inside the push block 53 is rotated to make the surface of the limiting screw 54 and the threaded hole 56 inside the fixing seat 55 be installed with internal threads, thereby limiting the push block 53 and allowing the insertion rod 52 to enter the slot 4, so that the first main board 1 and the second main board 2 are in the same plane, avoiding folding and use. When the limiting screw 54 in the push block 53 is installed with the internal thread of the fixing seat 55 away from the side of the first main board 1, the insertion rod 52 is limited in the groove body 51 to avoid the insertion rod 52 from shaking, which is used when the folding bridge is stored, and an adjusting nut 6 is provided to facilitate the rotation adjustment of the limiting screw 54.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
