Description

Technical Field

[0001] The utility model relates to the technical field of geocell, in particular to a geocell connector. Background Technique

[0002] A geocell connector is a three-dimensional reticulated grid structure, which can expand and contract freely, can be folded during transportation, and can be tensioned into a net during construction. Loose materials such as soil, gravel, and concrete are filled into it to form a structure with strong lateral restraint and large stiffness. It is mainly used to reinforce the subgrades of railways and highways, slope protection, sand fixation, and construction of retaining walls, etc. Using geocell connectors to build retaining walls is a commonly used construction method at present.

[0003] At present, there are many types and styles of existing geocell connectors. For example, a new type of connector for civil engineering geocells with the Chinese patent number CN205857152U. This patent sleeved a heat shrinkable film on the connector composed of a plug-in connector and a clamping connector, and then welded the plug-in connector and the clamping connector. The heat of welding caused the heat shrinkable film to shrink, and the shrunk heat shrinkable film tightly covered the connector. The heat shrinkable film has an anti-corrosion function, which prevents the civil engineering geocell connector from being corroded and makes the civil engineering geocell firmly connected when buried underground. However, with the replacement of civil engineering geocells, this patent no longer meets the requirements of existing civil engineering geocells because it requires welding the plug-in connector and the clamping connector, and the welding workload is large, resulting in poor practicability. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a geocell connector, which has the advantage of strong connectivity and solves the problem of poor practicability.

[0005] To achieve the above-mentioned purpose of strong connectivity, the utility model provides the following technical solution: A geocell connector includes a U-shaped connection component and a locking mechanism, and the U-shaped connection component is connected inside the locking mechanism;

[0006] The locking mechanism includes an upper fixing block and a lower fixing block. Two upper connecting plates are fixedly installed at the bottom of the upper fixing block. Two lower connecting plates are fixedly installed at the top of the lower fixing block. Positioning pins are fixedly installed at the bottom ends of the two upper connecting plates. T-shaped plates are fixedly installed on the opposite surfaces of the two lower connecting plates. Clamping plates are fixedly installed at the top ends of the two lower connecting plates.

[0007] Further, the U-shaped connection component includes a U-shaped connecting rod, bearings and protective sleeves. A set of bearings are fixedly installed at the left and right ends of the U-shaped connecting rod, and protective sleeves are fixedly connected to the outside of the two sets of bearings.

[0008] Furthermore, a semi-circular groove adapted to the top end of the U-shaped connecting rod is formed at the bottom of the upper fixing block, and two clamping grooves adapted to the bottom end of the U-shaped connecting rod are formed at the top of the lower fixing block.

[0009] Furthermore, fixing bolts are threadedly connected to both the left and right sides of the upper fixing block, and circular through holes adapted to the connecting ends of the fixing bolts are formed in the exteriors of the two clamping plates.

[0010] Furthermore, two connecting cavities adapted to the exteriors of the clamping plates are formed at the bottom of the upper fixing block, two positioning holes adapted to the exteriors of the positioning pins are formed at the top of the lower fixing block, T-shaped sliding grooves adapted to the exteriors of the T-shaped plates are formed in the opposite surfaces of the two upper connecting plates, and their connection relationship is a sliding connection.

[0011] Furthermore, the lateral peeling force at the open end of the U-shaped connecting rod is greater than 300 N, and the number of each group of bearings is two.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0013] 1. For this geogrid connector, by setting the locking mechanism, through the sliding connection relationship between the two T-shaped plates and the T-shaped sliding grooves on the upper connecting plate, the upper fixing block and the lower fixing block can be stably connected. Then, when the upper connecting plate and the lower connecting plate move to the top and the bottom respectively, the positioning pins and the clamping plates on their plate bodies will enter the corresponding positioning holes and connecting cavities, thereby enclosing and fixing the entire U-shaped connection assembly, and also sealing the open end of the U-shaped connection assembly, greatly improving the connection performance of the connector. At the same time, the operation is relatively simple, which can effectively improve the work efficiency.

[0014] 2. For this geogrid connector, by setting the U-shaped connection assembly, the protective sleeves on both sides of the U-shaped connecting rod can be connected to multiple bearings, enabling the protective sleeves to have rotationality. Thus, the assembly can adjust the spacing of the geogrid by pushing the U-shaped connecting rod, making its applicability wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 5 , a geogrid connector in this embodiment includes a U-shaped connection component 1 and a locking mechanism 2, and the U-shaped connection component 1 is connected inside the locking mechanism 2;

[0023] The locking mechanism 2 includes an upper fixing block 201 and a lower fixing block 202. Two upper connecting plates 203 are fixedly installed at the bottom of the upper fixing block 201. Two lower connecting plates 205 are fixedly installed at the top of the lower fixing block 202. Positioning pins 204 are fixedly installed at the bottom ends of the two upper connecting plates 203. At the same time, two positioning holes adapted to the outside of the positioning pins 204 are also opened at the top of the lower fixing block 202. T-shaped plates 206 are fixedly installed on the opposite surfaces of the two lower connecting plates 205. At the same time, T-shaped chutes adapted to the outside of the T-shaped plates 206 are also opened on the opposite surfaces of the two upper connecting plates 203, and their connection relationship is a sliding connection. Clamping plates 207 are fixedly installed at the top ends of the two lower connecting plates 205. Two connection cavities adapted to the outside of the clamping plates 207 are opened at the bottom of the upper fixing block 201. Through the sliding connection relationship between the two T-shaped plates 206 and the T-shaped chutes on the upper connecting plates 203, the upper fixing block 201 and the lower fixing block 202 can be stably connected. Then, when the upper connecting plate 203 and the lower connecting plate 205 move to the top and bottom respectively, the positioning pins 204 and the clamping plates 207 on their plate bodies will enter the corresponding positioning holes and connection cavities, thereby surrounding and fixing the entire U-shaped connection component 1, and also sealing the open end of the U-shaped connection component 1, greatly improving the connectivity of the connector, and at the same time, the operation is relatively simple, which can effectively improve the work efficiency.

[0024] In the case implementation, the U-shaped connection component 1 includes a U-shaped connecting rod 101, bearings 102, and protective sleeves 103. A set of bearings 102 are fixedly installed at both the left and right ends of the U-shaped connecting rod 101, and protective sleeves 103 are fixedly connected to the outside of the two sets of bearings 102. Among them, the protective sleeves 103 on both sides of the U-shaped connecting rod 101 can be connected to multiple bearings 102, enabling the protective sleeves 103 to have rotatability. Thus, this component can adjust the spacing of the geogrid by pushing the U-shaped connecting rod 101, making its applicability wider.

[0025] In the case implementation, a semi-circular groove adapted to the top end of the U-shaped connecting rod 101 is opened at the bottom of the upper fixing block 201, and two card slots adapted to the bottom end of the U-shaped connecting rod 101 are opened at the top of the lower fixing block 202. Thus, the U-shaped connection component 1 can be perfectly fitted onto the locking mechanism 2.

[0026] In the case implementation, fixing bolts 3 are threadedly connected to both the left and right sides of the upper fixing block 201, and circular through holes adapted to the connecting ends of the fixing bolts 3 are opened on the outside of the two clamping plates 207. Thus, when the clamping plates 207 enter the inside of the connecting cavity, the fixing bolts 3 can pass through the circular through holes on their plate bodies to fix the locking mechanism 2, which can effectively improve the fixing efficiency and also effectively ensure the stability of the connection.

[0027] In the case implementation, the transverse peeling force at the open end of the U-shaped connecting rod 101 is greater than 300 N, which can effectively prevent the U-shaped connecting rod 101 from breaking due to excessive peeling force.

[0028] During implementation, the following steps are carried out for operation:

[0029] 1) First, connect the geogrid through the U-shaped connection component 1;

[0030] 2) Then, snap the bottom end of the U-shaped connection component 1 onto the lower fixing block 202;

[0031] 3) Next, connect the T-shaped plate 206 to the T-shaped sliding groove on the upper connecting plate 203, and snap the top end of the U-shaped connection component 1 into the semi-circular groove of the upper fixing block 201;

[0032] 4) Finally, fix the locking mechanism 2 with two fixing bolts 3.

[0033] In summary, for this geocell connector, by setting the locking mechanism 2, due to the sliding connection relationship between the two T-shaped plates 206 and the T-shaped sliding grooves on the upper connecting plate 203, the upper fixing block 201 and the lower fixing block 202 can be stably connected. Then, when the upper connecting plate 203 and the lower connecting plate 205 move to the top and bottom respectively, the positioning pins 204 and the clamping plates 207 on their plate bodies will enter the corresponding positioning holes and the connecting cavities, thereby being able to enclose and fix the U-shaped connecting component 1 as a whole, and also being able to seal the open end of the U-shaped connecting component 1, greatly improving the connectivity of this connector. At the same time, the operation is relatively simple, which can effectively improve the work efficiency, and solves the problem that the patent is not suitable for practical use because it requires welding plug-in parts and clamping parts, and the welding workload is large, which no longer meets the requirements of the existing geocells.
