Description

Technical Field

[0001] The present invention relates to the technical field of protective net connection, and in particular to a quick-install, self-locking, all-biodegradable protective net connection structure. Background Art

[0002] With the deepening of environmental protection concepts and the demand for sustainable development, fully biodegradable protective nets have emerged. Made of biodegradable materials, these nets can effectively reduce the pollution caused by discarded traditional protective nets.

[0003] Traditional protective nets are mostly connected by means of pins, bundling or welding. Although the pin connection method can achieve the combination of protective nets to a certain extent, the operation process is cumbersome and requires construction workers to accurately align and insert the pins, which consumes a lot of time and manpower. Especially in large-scale protective net laying operations, the efficiency is extremely low. Bundling connections usually rely on tools such as ropes. Not only is the connection unstable, but the ropes are prone to wear and breakage in harsh environments such as wind and sun, causing the protective net connection to loosen and reduce the protective effect. Moreover, when dismantling the bundled protective net, the process of untying the ropes is also quite time-consuming and labor-intensive. This limits its application scenarios to a certain extent and increases the difficulty and cost of construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a quick-install, self-locking, all-bio-based degradable protective net connection structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a quick-install, self-locking, fully bio-based degradable protective net connection structure, comprising a shell, on which is provided a group of hooks capable of connecting the protective net, and an upper cover rotatably connected to the shell; the hooks are provided with a group of limiting components capable of driving them to retract and limit the protective net; the limiting components are provided with a driving component capable of canceling the limit of the hooks.

[0006] As a further solution of the present invention, the limiting assembly includes a connecting plate fixedly connected to the hook, and a first return spring is fixedly connected between the two connecting plates; a wedge block is provided at the opposite end of the connecting plate, and a driving block is provided above the inclined surface of the wedge block, which can drive it to move into the shell, and a driving rod is fixedly connected to the driving block, and the driving rod is slidably connected to the upper cover in the up and down directions.

[0007] As a further solution of the present invention, the driving assembly includes a limiting rod capable of moving the driving rod, and the limiting rod is provided with a groove that can be used for vertical and horizontal displacement of the driving rod. A first spring is arranged between the driving rod and the limiting rod, and the movable groove of the limiting rod is slidably connected to a limiting bar, and the limiting bar is slidably connected to the L-shaped sliding groove opened on the driving rod.

[0008] As a further solution of the present invention, a slot for limiting is provided on the wedge block, and a block that can be engaged with the slot is fixedly connected to the driving block; the coordinated design of the slot and the block provides a reliable guarantee for the connection of the protective net; the mutual engagement of the slot and the block can effectively limit the movement of the wedge block, so that the hook remains in a stable state after fixing the protective net, and prevents it from loosening and falling off; and this structure is simple and compact, and the block automatically snaps into the slot during installation, and precise limiting can be achieved without additional complicated operations. It can also be easily separated during disassembly through reasonable design, taking into account both the stability of the connection and the convenience of operation, thereby improving the practicality and reliability of the protective net connection structure.

[0009] As a further solution of the present invention, a limiting column is fixedly connected to the upper cover, the upper end of the limiting column passes through and extends to the top of the limiting rod, the limiting column is slidably connected to the limiting rod, and a second return spring is sleeved on the limiting column, and the second return spring is located between the limiting rod and the upper cover. When working, the second return spring can separate the driving block from the wedge block, that is, when the slot is separated from the block, the second return spring can restore the limiting rod to its initial position.

[0010] As a further solution of the present invention, the upper cover is rotatably connected to a limiting opening for limiting the position with the shell.

[0011] As a further solution of the present invention, limiting blocks for rolling and limiting the anti-slip net on the hook are fixedly connected to both sides of the upper cover and located directly above the hook.

[0012] As a further solution of the present invention, a snap-in opening for snapping in the snap-in block is provided on the housing.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The manual drive rod moves downward, and the drive rod drives the drive block to act on the inclined surface of the wedge block, so that the two wedge blocks move closer to each other. The wedge block drives the hook to move into the shell through the connecting plate, and the hook drives the protective net into the shell, ensuring that the connection between the hook and the protective net will not be easily worn or broken due to harsh environments such as wind and sun, resulting in the separation of the protective net and the hook. It realizes a quick-install and self-locking connection of the protective net, which is simple to operate and improves work efficiency.

[0014] 2. During disassembly, the limit bar is moved to cancel the limit between the drive rod and the limit rod. With the help of the force of the first return spring, the drive block is separated from the wedge block. The connecting plate extends the hook under the action of the first return spring, making it easy to remove the protective net. The operation is simple and efficient, greatly improving the efficiency of installation and disassembly. On the other hand, it is convenient for the replacement and maintenance of the protective net, effectively reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS
