Technical Field

[0001] The utility model relates to the technical field of security equipment, in particular to a foldable municipal iron horse. Background Art

[0002] Municipal iron horses, also known as iron horse guardrails, construction iron horses, construction iron guardrails, municipal construction guardrails, etc., are a safety warning and maintenance product mainly used for road construction, temporary isolation or isolation of people in large public places. They play an important role in protecting pedestrian safety, separating traffic flow lines, providing visual guidance and maintaining construction order.

[0003] The patent document with application number 202320397161.3 discloses a foldable mobile iron horse and iron horse assembly, including a left bracket and a right bracket, the left bracket and the right bracket can be rotatably connected, and the bottom of the left bracket and the bottom of the right bracket are both provided with a base, and the lower end of the base is provided with a universal wheel that can be extended and retracted up and down.

[0004] However, most traditional municipal iron horses are not foldable. These municipal iron horses usually adopt a fixed structure and are relatively sturdy overall, but they also take up a large space accordingly. Especially in temporary traffic control or large-scale events (such as concerts and sports events), the road and venue layout may need to be frequently adjusted according to actual conditions. Due to their fixed shape, traditional municipal iron horses are difficult to move and transport quickly, which increases the workload and time cost of staff. Utility Model Content

[0005] The utility model discloses a foldable municipal iron horse, which aims to solve the technical problem that most traditional municipal iron horses are non-foldable. These municipal iron horses usually adopt a fixed structure and are relatively strong as a whole, but correspondingly they also take up a large space. Especially at temporary traffic control or large-scale events (such as concerts and sports events), the layout of roads and venues may need to be frequently adjusted according to actual conditions. Traditional municipal iron horses are difficult to move and carry quickly due to their fixed shape, which increases the workload and time cost of staff.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A foldable municipal iron horse comprises a left bracket and a right bracket, wherein the left bracket and the right bracket each comprise a first crossbar and a first upright column, and further comprises:

[0008] Adjustment mechanism: located at the bottom of the first crossbar;

[0009] Folding mechanism: located on the circumferential outer wall of the first cross bar, the folding mechanism includes eight connecting frames, two fixing clamps and two mounting rods. A second cross bar is provided near the bottom end of the circumferential outer wall of the first column. The top of the first column is fixedly connected to the first cross bar. Four vertical rods are provided between the first cross bar and the second cross bar. The two sides of the two fixing clamps are hinged to the two first cross bars and the two second cross bars respectively. Two limiting rods are provided between the two fixing clamps. Two adjacent connecting frames are hinged to the circumferential outer wall of the first cross bar. One end of the mounting rod is installed between the two adjacent connecting frames.

[0010] When the municipal iron horse needs to be folded, first rotate the two unfolded mounting rods and eight connecting frames ninety degrees around the hinge point (clockwise or counterclockwise) to make the mounting rods close to and close to the surface of the first cross bar, then press the fixing clip and push the two first cross bars closer to each other, so that the municipal iron horse can be folded, reducing the floor space occupied by the municipal iron horse when stored. When the municipal iron horse needs to be moved, the knob can be turned to drive the threaded rod to rotate while the universal wheel moves downward. At this time, the operator can quickly drive the municipal iron horse to move by pulling the mounting rod with both hands. When the municipal iron horse moves to the appropriate position, the threaded rod is rotated in the opposite direction to drive the universal wheel to move upward and retract, so that the bottom of the municipal iron horse contacts the ground, avoiding excessive manpower and time costs in transporting the municipal iron horse, and also reducing the damage to the municipal iron horse during transportation.

[0011] In a preferred solution, the fixing clamp is an isosceles trapezoidal structure.

[0012] This setting can limit the rotation range of the first cross bar. The isosceles trapezoidal design enables the fixing clamp to utilize space more efficiently when folding or unfolding, reducing unnecessary gaps or overlaps, making the overall structure of the municipal iron horse more compact and practical.

[0013] In a preferred solution, the adjustment mechanism includes two connecting tubes and two bases, the connecting tube is located at the bottom end of the first column, the circumferential outer wall of the connecting tube is provided with four limiting holes, the circumferential outer wall of the base is provided with two limiting grooves, the inner wall of the limiting groove is provided with a telescopic spring, one end of the telescopic spring is provided with a dome protrusion, the dome protrusion is adapted to the limiting hole, the circumferential inner wall of the connecting tube is provided with a guide groove, and the guide groove is communicated with the four limiting holes.

[0014] When the position of the base needs to be adjusted, the operator presses the two dome protrusions at the same time, and the telescopic spring is forced to shorten in the limit groove. At this time, the dome protrusion will retract into the limit hole. Then the operator holds the base with the other hand and rotates it, so that the two dome protrusions can rotate in the guide groove. At this time, the two dome protrusions will slide out of the inner walls of the other two limit holes after rotating a certain angle in the guide groove. The two dome protrusions lose the pressing force and under the elastic force of the telescopic spring, the two dome protrusions are smoothly clamped on the inner walls of the other two limit holes, thereby realizing the angular position adjustment of the base according to actual handling or moving requirements.

[0015] As can be seen from the above, a foldable municipal iron horse includes a left bracket and a right bracket, wherein the left bracket and the right bracket each include a first crossbar and a first column, and further includes:

[0016] Adjustment mechanism: located at the bottom of the first crossbar;

[0017] Folding mechanism: Located on the circumferential outer wall of the first crossbar, the folding mechanism includes eight connecting frames, two fixing clamps and two mounting rods. A second crossbar is provided near the bottom end of the circumferential outer wall of the first column. The top end of the first column is fixedly connected to the first crossbar. Four vertical rods are provided between the first crossbar and the second crossbar. The two sides of the two fixing clamps are hinged to the two first crossbars and the two second crossbars respectively. Two limiting rods are provided between the two fixing clamps. Two adjacent connecting frames are hinged to the circumferential outer wall of the first crossbar. One end of the mounting rod is installed between the two adjacent connecting frames. The foldable municipal iron horse provided by the utility model has a quick folding and storage function, which reduces the floor space of the iron horse, avoids excessive manpower and time costs in transporting and moving the municipal iron horse, and also reduces the technical effect of damage to the iron horse during transportation.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0024] The foldable municipal iron horse disclosed by the utility model is mainly used in scenarios where traditional municipal iron horses are mostly non-foldable. These municipal iron horses usually adopt a fixed structure and are relatively sturdy as a whole, but they also take up a larger space accordingly. This is especially true in scenarios where temporary traffic control or large-scale events (such as concerts and sports events) require frequent adjustments to the layout of roads and venues according to actual conditions. Traditional municipal iron horses are difficult to move and transport quickly due to their fixed form, which increases the workload and time cost of staff.

[0025] Reference Figure 1 、 Figure 2 and Figure 3 A foldable municipal iron horse comprises a left bracket and a right bracket, each of which comprises a first crossbar 1 and a first column 2, and further comprises:

[0026] Adjustment mechanism: located at the bottom of the first crossbar 1;

[0027] Folding mechanism: Located on the circumferential outer wall of the first cross bar 1, the folding mechanism includes eight connecting frames 6, two fixing clamps 5 and two mounting rods 9. A second cross bar 8 is provided near the bottom end of the circumferential outer wall of the first column 2. The top of the first column 2 is fixedly connected to the first cross bar 1. Four vertical rods 4 are provided between the first cross bar 1 and the second cross bar 8. The two sides of the two fixing clamps 5 are hinged to the two first cross bars 1 and the two second cross bars 8 respectively. Two limiting rods 16 are provided between the two fixing clamps 5. The two adjacent connecting frames 6 are hinged to the circumferential outer wall of the first cross bar 1, and one end of the mounting rod 9 is installed between the two adjacent connecting frames 6.

[0028] Among them, the fixed clamp 5 is of an isosceles trapezoid structure. This setting can limit the rotation range of the first crossbar 1. The isosceles trapezoid design enables the fixed clamp 5 to make more efficient use of space when folding or unfolding, reducing unnecessary gaps or overlaps, and making the overall structure of the municipal iron horse more compact and practical.

[0029] During the specific use process, the connecting frame 6 is of an "L" - shaped structure. This setting enables the iron horses to be stacked more compactly when folded, reducing the need for storage space. At the same time, it is also convenient for loading and unloading the iron horses during transportation, and the cooperation of the connecting frame 6 and the first column 2 limits the rotation range of the mounting rod 9.

[0030] During the specific implementation process, a threaded rod 13 is connected to the circumferential outer wall of the mounting rod 9 by threads. One end of the threaded rod 13 is provided with a universal wheel 14, and a knob is provided at the end of the threaded rod 13 away from the universal wheel 14. By rotating the knob, the threaded rod 13 is driven to rotate, and then the universal wheel 14 moves up and down, and the height position of the universal wheel 14 can be adjusted according to the actual moving requirements of the municipal iron horse.

[0031] Among them, the mounting rod 9 is of a "U" - shaped structure. This setting makes the structure more stable, plays a role in connecting the universal wheel 14 and the threaded rod 13, and is convenient for the operator to drag the long side of the mounting rod 9 to move the iron horse.

[0032] Specifically, when the municipal iron horse needs to be folded, first rotate the two unfolded mounting rods 9 and eight connecting frames 6 around the hinge point clockwise or counterclockwise by 90 degrees, so that the mounting rods 9 approach and stick to the surface of the first crossbar 1. Then hold the fixed clamp 5 still and push the two first crossbars 1 closer to each other, so that the municipal iron horse can be folded, reducing the floor area occupied by the municipal iron horse during storage. When the municipal iron horse needs to be moved, by rotating the knob, while driving the threaded rod 13 to rotate, the universal wheel 14 moves downward. At this time, the operator can quickly move the municipal iron horse by pulling the two mounting rods 9 with both hands. After the municipal iron horse moves to the appropriate position, rotate the threaded rod 13 in the reverse direction to drive the universal wheel 14 to move upward and retract, so that the bottom of the municipal iron horse contacts the ground, avoiding excessive labor and time costs for handling the municipal iron horse, and also reducing the damage of the municipal iron horse during handling.

[0033] Refer to Figure 1 and Figure 4In a preferred embodiment, the adjustment mechanism includes two connecting tubes 11 and two bases 10. The connecting tube 11 is located at the bottom end of the first column 2. Four limiting holes are provided on the circumferential outer wall of the connecting tube 11. Two limiting grooves are provided on the circumferential outer wall of the base 10. A telescopic spring 15 is provided on the inner wall of the limiting groove. A dome protrusion 12 is provided at one end of the telescopic spring 15. The dome protrusion 12 is adapted to the limiting hole. A guide groove is provided on the circumferential inner wall of the connecting tube 11. The guide groove is communicated with the four limiting holes.

[0034] Specifically, when the position of the base 10 needs to be adjusted, the operator presses the two dome protrusions 12 at the same time, and the telescopic spring 15 is forced to shorten in the limit groove. At this time, the dome protrusion 12 will retract into the limit hole, and then the other hand holds the base 10 and rotates it, so that the two dome protrusions 12 can rotate in the guide groove. At this time, the two dome protrusions 12 will slide out of the inner walls of the other two limit holes after rotating a certain angle in the guide groove. The two dome protrusions 12 lose the pressing force and under the elastic force of the telescopic spring 15, the two dome protrusions 12 are smoothly clamped on the inner walls of the other two limit holes, thereby realizing the angular position adjustment of the base 10 according to actual handling or movement requirements.

[0035] Reference Figure 1 In a preferred embodiment, the circumferential outer walls of the two first columns 2 are respectively provided with two lock holes 3 and two lock hooks 7. The lock holes 3 and the lock hooks 7 are used in conjunction with each other to connect several iron horses to form an iron horse assembly.

[0036] Working principle: When the municipal iron horse needs to be folded, first rotate the two unfolded mounting rods 9 and the eight connecting frames 6 clockwise or counterclockwise ninety degrees around the hinge point, so that the mounting rod 9 is close to and close to the surface of the first cross bar 1, then press the fixing clip 5 and push the two first cross bars 1 close to each other, so that the municipal iron horse can be folded, reducing the floor space of the municipal iron horse when stored. When the municipal iron horse needs to be moved, the knob can be turned to drive the threaded rod 13 to rotate while the universal wheel 14 moves downward. At this time, the operator can quickly drive the municipal iron horse to move by pulling the mounting rod 9 with both hands. When the municipal iron horse moves to the appropriate position, the threaded rod 13 is rotated in the opposite direction, thereby driving the universal wheel 14 to move upward and retract, so that the bottom of the municipal iron horse contacts the ground, avoiding excessive manpower and time costs in transporting the municipal iron horse, and also reducing the damage to the municipal iron horse during transportation.

[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
