Description

Technical Field

[0001] The utility model relates to the technical field of mechanical guardrails, and particularly relates to a detachable and anti-dropping guardrail. Background Technique

[0002] As a new type of protective facility, the integrated guardrail can trace its technical origin back to the improvement and innovation of traditional guardrails. With the continuous improvement of safety protection requirements in places such as road traffic, industrial parks, and residential communities, the integrated guardrail has won the favor of the market with its excellent protective performance.

[0003] However, the traditional integrated guardrail designed above still has some disadvantages in actual use: currently, road guardrails are all assembled, integrated guardrails; the connection parts of traditional guardrails are all integrated, making disassembly inconvenient. And after the traditional guardrail is impacted, the guardrail will fall apart and fall off, with a simple structure and poor fastening performance, unable to prevent the railing from falling off; and it is extremely inconvenient to disassemble the guardrail when moving it for use.

[0004] Therefore, we designed a detachable and anti-dropping guardrail to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a detachable and anti-dropping guardrail to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, a detachable and anti-dropping guardrail provided by the utility model includes two symmetrical guardrail bases and two groups of guardrails arranged between the two guardrail bases. At both ends of each group of guardrails, a locking mechanism is provided. The locking mechanism includes a spherical head arranged on the guardrail base. On one side of the spherical head, a ball head connection card is provided. The ball head connection card abuts against the lower bottom of the spherical head. On the other side of the ball head connection card, a clamp is fixedly connected. On the other side of the clamp, a connecting rotating shaft is provided. The locking mechanism is arranged at both ends of each group of guardrails, realizing double fixation between the guardrail and the guardrail base, and effectively preventing the guardrail from shaking or falling off during use.

[0007] Furthermore, the locking mechanism further includes a card interface fixedly connected to the other end of the clamp. The card interface is adapted to the connecting rotating shaft and slides on the connecting rotating shaft. A connecting piece is also arranged outside the connecting rotating shaft. The adaptation design of the card interface and the connecting rotating shaft ensures the precise positioning of the connecting piece during the assembly process, reduces the problem of loose connection caused by position deviation, and at the same time simplifies the installation and disassembly process. The user only needs to align the card interface with the connecting rotating shaft and slide it into place to complete the connection; similarly, when disassembling, only the reverse operation is required.

[0008] Furthermore, the connecting piece includes a spherical cabin clamped on the top of the spherical head, the connecting rotating shaft is inserted into the connecting piece, and the other end of the connecting piece is used for fixed connection with the guardrail. Two symmetrical fixing screws are fixedly inserted between the connecting piece and the guardrail. The symmetrical fastening screws can evenly distribute the force at the connection, ensuring that the guardrail structure can remain stable when subjected to external force, reducing the risk of loosening or deformation, thereby improving the stability and safety of the overall structure.

[0009] Furthermore, the clamp is detachably connected with a fastening bolt, which passes through the clamp. The fastening bolt passes through one end of the fastening bolt and is fixedly wound with a first spring, and the other end of the fastening bolt is wound with a second spring. The first spring and the second spring are different in size and thickness, and their function is to install the fastening. At the same time, the elasticity of the spring can make the clamp act on the sphere more tightly to prevent it from falling off.

[0010] Furthermore, a "U"-shaped hollow is provided on one side of the two guardrail bases close to the guardrail, and a mounting platform corresponding to the spherical head is installed in the "U"-shaped hollow. The "U"-shaped hollow design provides convenience for the installation process. The installer can more easily align and insert the spherical head into the mounting platform.

[0011] Furthermore, a platform smaller than the radius of the spherical head is provided at the end close to the connecting piece. The design of the platform provides a clear contact surface and positioning reference between the spherical head and the connecting piece, which helps to find the connection point quickly and accurately during the installation process, reduces the time for alignment and adjustment, and improves work efficiency.

[0012] Furthermore, a buffer is provided at the fixed connection between the connecting member and the guardrail, and the buffer includes two buffer rings arranged on the connecting member, one of the buffer rings is fixedly connected to the connecting member, and the other buffer ring is used to be fixedly sleeved on the guardrail. The buffer can effectively maintain the clamping force of the clamp on the guardrail to ensure the stability of the connection. Even when subjected to external impact or vibration, the elastic deformation ability of the spring can enable the clamp to maintain a close fit to the guardrail to prevent the connection from loosening or falling off.

[0013] Furthermore, a compression spring is fixedly connected between the two buffer rings, and the inner diameter of the compression spring is larger than the inner diameter of the guardrail.

[0014] Furthermore, the shape of the ball head connecting card and the spherical cabin are both spherical structures that are one-fourth of the shape of a round ball head. The spherical structure can evenly distribute the external pressure to the entire spherical surface. This feature enables the ball head connecting card and the spherical cabin to maintain a high stability when under pressure. Since the force is evenly applied, local stress concentration is reduced, thereby improving the bearing capacity of the overall structure.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: By inverting the spherical chamber on the sphere and installing a connecting rotating shaft on the connecting piece, when the connecting rotating shaft is fixedly connected, the clamping interface on the fixture is clamped with the connecting rotating shaft. After the clamping, the fixture rotates on the connecting rotating shaft, and then the fixture is clamped to the bottom of the ball head connection card; furthermore, the fastening bolt is inserted into the fixture, so that the first spring and the second spring at the bottom cooperate and abut against the top of the spherical chamber; the fixture and the spherical head are made to be fixed more tightly. With the arrangement of the fixture and the connecting piece, the reinstallation and removal process of the guardrail becomes simple and fast. Compared with the integrally connected guardrail, only by simply matching and locking the fixture with the spherical head, the rapid installation of the guardrail can be achieved;

[0016] The buffer ring at the other end of the connecting piece is sleeved on the corresponding guardrail in a matching manner, and another buffer ring is also fixed on the guardrail. Through the arrangement of the buffer ring and the compression spring, the clamping force of the fixture and the connecting piece on the guardrail can be effectively maintained, ensuring the stability of the connection and preventing the connection from loosening or falling off.
