Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a combination formula model framework for road and bridge design, includes the pontic 1, both ends all are equipped with fixing base 2 about the pontic 1, and 2 downside of fixing base are equipped with

pier model

3, and 3 top surface sliding connection of pier model have a removal seat 5, and removal seat 5 top surfaces are connected with connecting rod 4, and 1 below of pontic is equipped with adjusts pole 6.

Concretely, 2 medial surface of fixing base and 1 end connection of pontic are fixed, and pontic 1 is made by rubber materials, and slot 201 has been seted up to 2 bottom surfaces of fixing base, and slot 201 inner wall is the loop configuration and has seted up two draw-in grooves 202, and sliding connection has stopper 203 in the draw-in groove 202, and inclined plane 205 has been seted up to the inner bottom surface of stopper 203, and stopper 203 outer end terminal surface passes through spring 204 and draw-in groove 202 inner wall connection is fixed.

Further, the top surface of connecting rod 4 is protruding type structure setting, and connecting rod 4 upper end outer wall sliding connection has regulating block 401, and both ends are toper structure setting about regulating block 401, regulating block 401 outer wall and the inner terminal surface movable contact of stopper 203.

Still further, the inner wall of the lower end of the pier model 3 is rotatably connected with a threaded rod 301, and the outer wall of the upper end of the threaded rod 301 is in threaded connection with the inner wall of the movable seat 5.

Besides, adjust 6 left end outer walls of pole and pass and be close to 2 outside terminal surfaces of fixing base on right side and extend to the left side and be connected with 2 medial surfaces of left fixing base rotation, adjust 6 right-hand member outer walls of pole and be close to 2 threaded connection of fixing base on right side, adjust 6 right-hand member terminal surfaces of pole and connect and be fixed with knob 601.

The working principle is as follows: when the bridge model needs to be assembled, firstly, the bridge model 3 is connected with the fixed seat 2, the connecting rod 4 is inserted into the slot 201, then the connecting rod 4 can be fixed in the fixed seat 2 under the action of the limit block 203, so that connection is realized, then the height of the movable seat 5 can be adjusted according to needs, the movable seat 5 in threaded connection can move upwards by rotating the threaded rod 301, so that the adjusting function is realized, thereby the model of a bridge is combined, when the arch bridge needs to be designed, the adjusting rod 6 can be rotated to drive the fixed seat 2 at the left end to move towards the right side, so that the bridge body 1 made of rubber materials is deformed, an arc-shaped structure is formed, thereby the arch bridge model can be formed, then when the arch bridge model needs to be disassembled, the fixed seat 2 is pressed downwards, so that the limit block 203 moves to the lower side of the adjusting block 401, then, the fixing seat 2 is pulled upwards, so that the limiting block 203 can drive the adjusting block 401 to ascend, when the adjusting block 401 contacts with the bottom surface of the upper end of the connecting rod 4, the limiting block 203 can be retracted into the clamping groove 202, the fixing seat 2 can be taken down from the connecting rod 4, and the detachment is completed.
