Description

Technical Field

[0001] This utility model relates to the field of roadblocks, specifically a convenient roadblock. Background Technology

[0002] Roadblocks are commonly used during road control operations. Besides serving a guiding function, roadblocks also need to be stable and not easily tipped over once placed. However, existing roadblocks have some problems. While they are convenient to move and transport, they are usually made of plastic. These one-piece plastic roadblocks are easy to move, but they are generally small, and because plastic is lightweight, they are easily tipped over and damaged by impacts, resulting in a short lifespan. To improve the anti-tipping and sturdiness of roadblocks, steel must be used. Roadblocks made of steel are large, heavy, difficult to move and transport, and have high transportation costs.

[0003] Therefore, there is an urgent need to develop a convenient roadblock that retains the characteristics of being resistant to tipping over and damage, while also being easy to move and store. Summary of the Invention

[0004] The technical solution of this utility model is: a convenient roadblock, including a main shaft, a main shaft head, a cone head seat, and support rods. The main shaft is telescopically located at the center of the cone head seat, and the upper end of the main shaft extends above the cone head seat. The main shaft head is installed at the upper end of the main shaft. The cone head seat includes a middle part and an outer extension seat. The support rods are in multiple sets, and each set of support rods is rotatably hinged to the outer extension seat of the cone head seat.

[0005] Preferably, each set of support rods includes side support rods and bottom support rods. The lower end of the main shaft is a bottom foot seat, which has a number of foot interfaces equal to the number of support rods. The upper end of the side support rod is hinged to the outer extension seat of the cone head seat, the lower end of the side support rod is hinged to the outer end of the bottom support rod, and the inner end of the bottom support rod is hinged to the foot interface.

[0006] As a further preferred option, the number of support rods is preferably three sets.

[0007] As a further preferred embodiment, the upper end of the spindle head is blunt, and after the side support rod is opened, the side of the spindle head, the outer extension seat of the cone head seat, and the side support rod form an inclined slope.

[0008] As a further preferred embodiment, the lower surfaces of the foot interface and the outer extension seat are both hollow structures. The width of the side support rod is narrower than the width of the outer extension seat, the width of the bottom support rod is narrower than the width of the side support rod, and the width of the inner end of the bottom support rod is narrower than the foot interface. This allows the side support rod to fold downward relative to the outer extension seat, the bottom support rod to fold upward relative to the side support rod, and the bottom support rod to fold downward relative to the foot interface.

[0009] As a further preferred option, the side support rod is made of channel steel.

[0010] Preferably, the conical head seat further includes a locking pin block equipped with a spring pin. The upper part of the spindle is provided with a socket. When the spindle descends, the spring pin pops out into the socket to fix the height position of the spindle.

[0011] As a further preferred embodiment, the bottom end of the side support rod is provided with a standing surface. When the main shaft descends to the bottom, the bottom support rod is in a horizontal state, the side support rod opens outward, and the standing surface of the side support rod is also in a horizontal state.

[0012] The beneficial effects of this utility model are as follows: This utility model has an integral structure. When in use, the support rod is opened and locked with a spring pin. The overall structure is stable and pressure-resistant, and has good anti-tipping performance. When not in use, the support rod can be folded and retracted, making it easy to store, move and transport. It is very convenient to use and improves the efficiency of traffic control.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-4As shown, a convenient roadblock includes a main shaft 5, a main shaft head 2, a cone head seat 1, and support rods. The main shaft 5 is telescopically located at the center of the cone head seat 1, with its upper end extending above the cone head seat 1. The main shaft head 2 is mounted on the upper end of the main shaft 5. The cone head seat 1 includes a central part and an outer extension seat 9. The support rods are in multiple sets, and each set of support rods is rotatably hinged to the outer extension seat 9 of the cone head seat 1.

[0021] In this embodiment, each set of support rods includes a side support rod 6 and a bottom support rod 7. The lower end of the main shaft 5 is a bottom foot 8. The bottom foot 8 is provided with a number of foot interfaces 10 equal to the number of support rods. The upper end of the side support rod 6 is hinged to the outer extension seat 9 of the cone head seat 1. The lower end of the side support rod 6 is hinged to the outer end of the bottom support rod 7. The inner end of the bottom support rod 7 is hinged to the foot interface 10.

[0022] In this embodiment, three sets of support rods are preferred. The three sets of support rods form a triangular pyramid structure roadblock, which has good stability and good resistance to tipping and compression.

[0023] In this embodiment, the upper end of the spindle head 2 is blunt, and after the side support rod 6 is opened, the side of the spindle head 2, the outer extension seat 9 of the cone head seat 1, and the side support rod 6 form an inclined slope. The blunt structure is to prevent bumps during the process of picking up the roadblock, so that the user is not easily injured and has good safety performance.

[0024] In this embodiment, the lower surfaces of the foot interface 10 and the outer extension seat 9 are both hollow structures. The width of the side support rod 6 is narrower than the width of the outer extension seat 9, the width of the bottom support rod 7 is narrower than the width of the side support rod 6, and the width of the inner end of the bottom support rod 7 is narrower than the foot interface 10. This allows the side support rod 6 to fold downward relative to the outer extension seat 9, the bottom support rod 7 to fold upward relative to the side support rod 6, and the bottom support rod 7 to fold downward relative to the foot interface 10.

[0025] In this embodiment, the side support rod 6 is a channel steel.

[0026] In this embodiment, the cone head seat 1 also includes a pin locking block 3, which is equipped with a spring pin 4. The upper part of the spindle 5 is provided with a socket 11. When the spindle 5 descends, the spring pin 4 pops out into the socket 11 to fix the height position of the spindle 5.

[0027] In this embodiment, the bottom end of the side support rod 6 is provided with a standing surface 12. When the main shaft 5 descends to the bottom, the bottom support rod 7 is in a horizontal state, the side support rod 6 opens outward, and the standing surface 12 of the side support rod 6 is also in a horizontal state.

[0028] The convenient roadblock of this utility model, when in the open state, is as follows: Figure 1 As shown, when the main shaft 5 descends to the bottom, the spring pin 4 pops out into the insertion hole 11, and the main shaft 5 stops rising and falling. At the same time, the bottom support rod 7 and the side support rod 6 open, forming a stable triangular pyramid structure. When in the closed state, pulling out the spring pin 4 causes the main shaft 5 to rise. The side support rod 6 folds downward relative to the outer extension seat 9, and the bottom support rod 7 folds downward relative to the base interface 10 and upward relative to the side support rod 6. The bottom support rod 7 is then stored inside the side support rod 6. The entire convenient road barrier folds up like an umbrella, reducing the space it occupies and facilitating storage and transportation.
