Description

Technical Field

[0001] This utility model relates to the field of municipal road technology, specifically to a combined frame model for municipal road bridges. Background Technology

[0002] During construction, it is necessary to first design the structure of the building, road, or bridge to facilitate construction based on the design data. In the design process, designers often construct architectural models to represent the shape of the building, providing a more intuitive understanding of its form.

[0003] Chinese patent CN218332962U discloses a modular model frame for municipal road bridge design. The structure includes a support beam, cable frame, crossbeam plate, and base plate. The support beam is fixed by inserting its bottom end into a groove and using a fixing pin through a through-hole and a fixing hole. The base plate contains multiple bases connected by telescopic rods to increase stability and increase the support area at the bottom, thus achieving better stability. Furthermore, the cable frame is fixed in a sliding groove using a slide rail, and the crossbeam plate is fixed by inserting it into a fixing groove at the upper end of the support beam connecting beam. This simplifies operation and allows for faster assembly and disassembly.

[0004] However, in the above technical solution, the support effect is improved by simply setting multiple sets of bases to increase the contact area with the ground or table. But when the bridge model is pushed by an external force and one side of the base is lifted off the ground, the base cannot block and reset the bridge model which is tilted. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a combined frame model for municipal road bridges.

[0010] Preferably, the base and the support legs are provided with parallel dovetail grooves, and the cable frame is connected with dovetail blocks, which are slidably connected to the dovetail grooves.

[0011] Preferably, the support leg consists of a fixed plate and a rotating plate. The fixed plate has a cavity and a notch. The rotating plate is rotatably connected to the notch, and one end of the rotating plate is detachably connected to the fixed plate.

[0015] Preferably, anti-slip pads are attached to all rotating plates.

[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0024] Example 1

[0025] like Figures 1-5 As shown, the present invention proposes a combined frame model for municipal road bridges, including a support frame 1, a cable frame 2, a cross plate 3, and an anti-tipping component. The support frame 1 is slidably connected to two symmetrically arranged cable frames 2. The cross plate 3 is placed on the support frame 1. The anti-tipping component is connected to the support frame 1. When the anti-tipping component is in use, multiple moving ends of the anti-tipping component move vertically to increase the contact points between the support frame 1 and the table to prevent it from tipping over.

[0026] In an optional embodiment, the mounting bracket includes a base 4 and support legs 5. The base 4 is U-shaped, and a plurality of symmetrically arranged support legs 5 are connected to the base 4.

[0027] In an optional embodiment, dovetail grooves 6 are provided on both the base 4 and the support leg 5, and dovetail blocks 7 are connected to both the cable frame 2, with the dovetail blocks 7 slidably connected to the dovetail grooves 6.

[0028] In an optional embodiment, the support leg 5 is composed of a fixed plate 8 and a rotating plate 9. The fixed plate 8 has an accommodating cavity and a notch. The rotating plate 9 is rotatably connected to the notch, and one end of the rotating plate 9 is detachably connected to the fixed plate 8.

[0029] In an optional embodiment, the fixed plate 8 is provided with a mounting groove, and a magnetic suction element 10 is connected in the mounting groove. The rotating plate 9 is connected with a magnetic attachment 11 that is magnetically connected to the magnetic suction element 10. The magnetic suction element 10 and the magnetic attachment 11 are respectively selected as permanent magnets and metal sheets containing alkali metal elements iron, cobalt and nickel. When the model is not yet assembled, the state of the support leg 5 can be maintained to prevent the rotating plate 9 from shaking.

[0030] Example 2

[0031] like Figures 2-4As shown, this utility model proposes a combined frame model for municipal road bridges. Compared with Embodiment 1, this embodiment describes the detailed structure of the anti-tipping component. The anti-tipping component includes a pressure block 12, a sliding rod 13, a stop block 14, an elastic element 15, a sliding block 16, and a fixing block 17. The number of pressure blocks 12 corresponds to the number of support legs 5. The pressure blocks 12 are slidably connected to the accommodating cavity opened on the support leg 5. Each pressure block 12 has an inclined surface. The pressure blocks 12 are detachably connected to the cable frame 2.

[0032] In an optional embodiment, each pressure block 12 is connected to a positioning block 18, and the positioning block 18 has an inclined surface. The positioning block 18 cooperates with the positioning groove 19 on the dovetail block 7. Both the positioning block 18 and the positioning groove 19 are triangular and can only move to one end and cannot move in the opposite direction. The two cooperate to position and guide the connection of the cable frame 2.

[0033] The number of sliding rods 13 corresponds to the number of pressure blocks 12. One end of the sliding rod 13 is connected to the pressure block 12. The stop block 14 is connected in the receiving cavity. The stop block 14 has a through hole for the sliding rod 13. The elastic element 15 is sleeved on the outside of the sliding rod 13. The two ends of the elastic element 15 are connected to the stop block 14 and the pressure block 12 respectively. The elastic element 15 is selected from, but is not limited to, springs. The sliding block 16 is connected to the sliding rod 13. The sliding block 16 has an inclined surface. The fixed block 17 is connected to the rotating plate 9. The fixed block 17 is slidably connected to the sliding block 16.

[0034] In an optional embodiment, anti-slip pads 20 are connected to the rotating plate 9; the anti-slip pads 20 are selected from, but are not limited to, rubber layers, to prevent the model from sliding on the table when it tipps over by increasing the friction with the ground.

[0035] In summary, when using this utility model, the operator inserts a cable frame 2 into the dovetail groove 6 opened on the base 4 and support leg 5 via the dovetail block 7. As the dovetail block 7 enters the dovetail groove 6, it comes into contact with the pressure block 12. The pressure block 12, under pressure, compresses the length of the elastic element 15, thus allowing the dovetail block 7 to enter the dovetail groove 6. As the dovetail block 7 gradually moves, the positioning block 18 on the pressure block 12 contacts its lower end face. When it moves to a certain position, the positioning blocks 18 on multiple pressure blocks 12 are all in a mating state with the positioning groove 19 to ensure accurate installation. Simultaneously, as the pressure block 12 accompanies the cavity... When the inner vertical movement is downward, it will drive the sliding rod 13 to move synchronously. The sliding block 16 on the sliding rod 13 moves down and contacts the fixed block 17 connected to the rotating plate 9. The fixed block 17 has a triangular cross-section, so when the two are in contact, the sliding block 16 moves down and pushes the rotating plate 9 and the fixed block 17 to rotate around the hinge point, so that the magnetic attachment 11 is disengaged from the magnetic suction 10, and the support leg 5 changes from an I-shape to a U-shape, increasing the number of contact points between the support frame 1 and the ground when it is tilted. When the support frame 1 is tilted under force, the rotating plate 9 will contact the ground first to prevent it from tilting.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
