Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, and in particular to a warning sign that prevents tipping. Background Technology

[0002] Warning signs use reflective materials to reflect light, improving visibility day and night or in adverse weather conditions, reminding passing vehicles or pedestrians to be aware of dangerous areas (such as accident scenes or construction zones) and reducing the risk of secondary accidents.

[0003] Chinese Patent Publication No. CN220439141U discloses an anti-tipping warning sign, including a base frame and a main body. A connecting plate is fixedly installed on the surface of the base frame, and a long rod is rotatably connected to the outer side of the connecting plate. A threaded cylinder is fixedly installed at one end of the long rod, and a hand-tightening bolt is fitted inside the threaded cylinder. A positioning hole is provided on the surface of the base frame. This invention, by setting this round rod, allows the main body of the warning sign to rotate along the round rod when exposed to wind, thereby reducing the contact area between the main body and the wind, reducing the wind force on the entire warning sign, and preventing the entire warning sign from easily tipping over. Furthermore, during the rotation of the round rod, the sleeve can compress a limiting ring through a spring, allowing the limiting ring to contact the circular ring, providing resistance to the rotation of the main body of the warning sign, thus preventing the main body of the warning sign from easily rotating and swaying in light winds, thereby achieving a better warning effect.

[0004] However, this device has the following drawbacks in use: although it can prevent the entire warning sign from easily tipping over, during indoor construction, the construction area is small, making it easy for construction workers and materials to come into contact with the device. When accidentally bumped into, there is no cushioning effect, which can cause injury to construction workers and damage to the device. To address these drawbacks, we propose an anti-tipping warning sign. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-tipping warning sign.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a warning sign to prevent tipping, comprising:

[0007] The base includes a hemispherical base and an internally threaded ring fixedly installed on the upper end of the hemispherical base;

[0008] A telescopic support cylinder, comprising a first telescopic cylinder, a second telescopic cylinder slidably mounted on the inner wall of the first telescopic cylinder, a third telescopic cylinder slidably mounted on the inner wall of the second telescopic cylinder, and limiting components both disposed on the surfaces of the second and third telescopic cylinders.

[0009] The warning sign structure includes a warning tape and an assembly component disposed on the upper end of the third telescopic cylinder.

[0010] Preferably, the limiting component includes mounting grooves that are both formed on the outer surfaces of the second and third telescopic cylinders, a limiting block that is slidably mounted on the inner wall of the mounting grooves, and a through hole formed on the inner walls of the first and second telescopic cylinders.

[0011] Preferably, the through hole allows the insertion of a limiting block.

[0015] Preferably, the outer surface of the first telescopic cylinder is provided with an external thread, and the external thread is adapted to the internal thread ring.

[0016] Preferably, the first telescopic cylinder, the second telescopic cylinder, and the third telescopic cylinder are all made of plastic.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The device uses a solid base and telescopic support cylinder to form a self-righting structure, which can buffer tilting during collisions, reduce rigid impacts, protect the safety of construction personnel and protect the device. The center of gravity of the device is concentrated at the bottom of the base. When it tilts under external force, the vertical line of the center of gravity deviates from the fulcrum and generates a restoring torque. After the external force is removed, the device will automatically reset without manual intervention, ensuring a continuous warning function and thus preventing the device from tipping over.

[0019] 2. The non-woven warning tape combined with the detachable assembly rope makes the installation of the warning sign structure convenient and inexpensive, suitable for frequent replacement of warning signs. The telescopic support cylinder can be expanded and retracted through the limiting component, thereby reducing the space required for the device after it is stored. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-6 This utility model provides a technical solution: an anti-tipping warning sign, comprising: a base, a telescopic support cylinder, and a warning sign structure.

[0030] The base includes a hemispherical base 10 and an internally threaded ring 11 fixedly installed on the upper end of the hemispherical base 10. The hemispherical base 10 is solid.

[0031] The telescopic support cylinder comprises a first telescopic cylinder 20, a second telescopic cylinder 21 slidably mounted on the inner wall of the first telescopic cylinder 20, a third telescopic cylinder 22 slidably mounted on the inner wall of the second telescopic cylinder 21, and limiting components disposed on the surfaces of the second telescopic cylinder 21 and the third telescopic cylinder 22. The limiting components include mounting grooves disposed on the outer surfaces of the second telescopic cylinder 21 and the third telescopic cylinder 22, limiting blocks 40 slidably mounted on the inner wall of the mounting grooves, and through holes disposed on the inner walls of the first telescopic cylinder 20 and the second telescopic cylinder 21, the through holes allowing the limiting blocks 40 to be inserted. A compression spring 41 is fixedly mounted on the inner wall of the mounting groove, and the other end of the compression spring 41 is fixedly connected to one side of the limiting block 40. Pulling the third telescopic cylinder 22 upwards causes it to slide out of the second telescopic cylinder 21. Simultaneously, the second telescopic cylinder 21 extends along the inner wall of the first telescopic cylinder 20. When the limiting block 40 moves to the through hole position, the compression spring 41 causes the limiting block 40 to insert into the through hole, thus limiting the third telescopic cylinder 22 and the second telescopic cylinder 21. This allows the telescopic support cylinder to unfold. Conversely, pressing the limiting block 40 causes the compression spring 41 to contract, disengaging the limiting block 40 from the through hole. This allows the second telescopic cylinder 21 to retract into the first telescopic cylinder 20, and the third telescopic cylinder 22 to retract into the second telescopic cylinder 21, thus storing the telescopic support cylinder.

[0032] The outer surface of the first telescopic cylinder 20 is provided with an external thread, which is compatible with the internal thread ring 11. After the external thread is screwed into the internal thread ring 11, the first telescopic cylinder 20 and the hemispherical base 10 can be assembled into one piece. The materials of the first telescopic cylinder 20, the second telescopic cylinder 21 and the third telescopic cylinder 22 are all made of plastic. When the first telescopic cylinder 20 and the hemispherical base 10 are assembled into one piece, the base will form a roly-poly structure with the telescopic support cylinder.

[0033] The warning sign structure includes a warning tape 30 and an assembly assembly set on the upper end of the third telescopic cylinder 22. The assembly assembly includes a baffle 50 fixedly installed on the upper end of the third telescopic cylinder 22, fixing rings 51 fixedly installed on the opposite sides of the baffle 50 and the hemispherical base 10, and assembly ropes 52 fixedly installed on the upper and lower surfaces of the warning tape 30. The warning tape 30 is made of non-woven fabric, and the surface of the warning tape 30 is respectively provided with warning slogans and reflective strips. When the telescopic support cylinder is unfolded, the warning tape 30 can be unfolded, and the assembly ropes 52 at both ends can be tied to the fixing rings 51 on the opposite sides of the baffle 50 and the hemispherical base 10, thereby unfolding the warning tape 30.

[0034] Because the telescopic support cylinder is a hollow shell and the base is a solid weight, the center of gravity can be concentrated on the base. Furthermore, the hemispherical base 10 adopts a hemispherical structure. Therefore, when construction personnel or construction materials touch the device and cause it to tilt, the device will tilt to buffer the impact force, thereby preventing damage to the device and construction personnel. At the same time, when the device tilts under external force, the vertical line of the center of gravity deviates from the fulcrum, generating a restoring torque and forming a resisting torque. Therefore, when the external force is removed, it will drive the device to return to an upright state, thereby preventing the device from tipping over.

[0035] Specifically, the working principle and operation method of this utility model are as follows:

[0036] The tumbler-like stabilizing structure adopts a combination design of a base and a hollow telescopic support cylinder, which concentrates the overall center of gravity at the bottom of the base. The hemispherical base 10 forms a single-point support surface. When tilted by external force, the vertical line of the center of gravity deviates from the fulcrum and generates a restoring torque. After the external force is removed, the device automatically resets. In the event of a collision, the tilting buffers the impact force, reducing the risk of device damage and personal injury.

[0037] The three-stage telescopic support system uses nested first telescopic cylinder 20, second telescopic cylinder 21 and third telescopic cylinder 22 to reduce the space occupied when the device is stored, and achieves quick locking through the limiting component. When stretched, the compression spring 41 pushes the limiting block 40 to automatically lock into the through hole and fix it. Pressing the limiting block 40 releases the lock and achieves storage.

[0038] Modular warning system: The non-woven warning tape 30 can be quickly assembled and disassembled via the assembly rope 52 and the fixing ring 51, which facilitates maintenance and updates.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
