Description

Technical Field

[0001] This utility model relates to the field of geocell technology, and more specifically, to a locking geocell. Background Technology

[0002] Geocells are made of a series of interwoven polymer strips or high-strength plastic sheets welded or woven using specific processes, forming a honeycomb-like cell structure with regular geometric shapes in space. They show broad application prospects in slope protection, roadbed reinforcement, and soft soil treatment.

[0003] Traditional geocells are constructed by thermoforming or mechanically riveting sheets together. However, the joints are prone to tensile or shear failure due to material fatigue and stress concentration, leading to separation between the sheets.

[0004] Chinese patent CN215758967U discloses a tenon clamp structure, which typically consists of three independent components: two connecting pieces with tenons and a central locking pin. During assembly, the tenons of the two connecting pieces are respectively inserted into pre-set mortises in each other, and then the locking pin is inserted laterally. This complex multi-component interlocking design also leads to increased manufacturing costs and cumbersome assembly processes. In practical applications, if the locking pin accidentally dislodges from the tenon clamp due to vibration, corrosion, or improper installation, it will directly cause the connection joint to loosen or even fail. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a locking geocell.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A lockable geocell includes several strips and locks. A through hole is provided at the node of every two adjacent strips. The lock includes a plug seat and a fastening plate. The limiting plate of the plug seat passes through the through hole on the strip and is locked and fixed by the fastening plate.

[0008] Furthermore, the connector includes a connector plate, which has a plurality of connecting rods, a limiting plate on each connecting rod, a lower connecting plate at the bottom of the connector plate, and a front baffle on the lower connecting plate.

[0009] Furthermore, the length of the connecting rod is greater than the thickness of the fastening plate.

[0010] Furthermore, the fastening plate is provided with a plurality of insertion holes that cooperate with the front baffle, and a limiting groove is formed on one side of the insertion hole.

[0011] Furthermore, the length of the insertion hole of the fastening plate is less than the length of the limiting plate, and the limiting plate can undergo elastic deformation when it passes through the insertion hole.

[0012] Furthermore, the plug-in base is integrally injection molded; the fastening plate is integrally injection molded.

[0013] Compared with existing technologies, the advantages of this invention are: This invention effectively disperses stress through a locking connection method, preventing tensile or shear failure at connection nodes due to material fatigue and stress concentration, thus improving the overall strength and stability of the geocell. The plug-in connector and the fastening plate are integrally injection molded, reducing the number of parts and manufacturing processes, and lowering manufacturing costs. Assembly is completed simply by passing the plug-in connector through the strip's through-hole and then fastening it with the fastening plate, eliminating the need for complex operations and multi-part coordination, thereby improving assembly efficiency.
