Geogrid rapid assembly buckle

Abstract

The utility model relates to the technical field of civil engineering, in particular to a geogrid rapid assembly buckle which comprises an upper pressing plate and a lower pressing plate, a portable installation mechanism is connected between the upper pressing plate and the lower pressing plate, an abutting supporting mechanism is arranged in the upper pressing plate, and a clamping groove is formed in the lower pressing plate. When the rapid assembly buckle for the geogrid is used, on one hand, the abutting plate can abut against the outer wall of the lower pressing plate all the time by means of the characteristic that the springs can synchronously generate counter-acting force under extrusion force, and therefore it is guaranteed that the geogrid can be pressed in the middle position by the abutting plate and the lower pressing plate all the time; and on the other hand, the counter-acting force of the spring is used for reversely pushing the matching structure for transmission, so that the positioning supporting block can directly abut against the nut block, and the nut block is not prone to falling off through the abutting supporting effect.

Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a geogrid quick assembly buckle. Background Art

[0002] Geogrid is an engineering material used for filtering and draining between soil and water. It is usually made of plastic or metal and has a porous structure. It can effectively filter particles in the soil and drain water to prevent soil erosion and sediment accumulation. Geogrid is widely used in land management, river regulation, flood control engineering and other fields. The assembly buckle is a connector for geogrid. The buckle can be used to quickly and easily assemble the geogrid together.

[0003] Patent No. "CN2654689Y" discloses a "geogrid connecting buckle", which achieves the installation of the geogrid by arranging installation connectors at both ends, one end is set as a groove structure, and the other end is set as a concave platform structure; since the geogrid buckle in the prior art only installs two geogrids through simple plates with nuts and bolts, this method does not achieve the effect of precise positioning and locking of the geogrid, and the geogrid can still be moved after installation, but the above-mentioned device has not made improvements to this problem, and the overall installation effect is poor. Summary of the invention

[0004] The purpose of the present utility model is to solve the above-mentioned problem and to propose a geogrid quick assembly buckle, which improves the existing geogrid quick assembly buckle which only installs two geogrids through simple plates with nuts and bolts. This method does not achieve the effect of accurately positioning the geogrid and locking the buckle, and the geogrid can still move after installation.

[0005] The locking mechanism is a function of the locking cam being affixed to the locking cam and the retaining member being affixed to the locking cam, the locking cam being configured to lock the locking cam and the retaining member being affixed to the locking cam.

[0006] Preferably, the resistance support mechanism includes a limiting sleeve and a limiting piston rod, the interior of the upper pressed plate is set as a cavity structure, and the limiting sleeves are arranged at equal intervals on the inner wall of the top end of the upper pressed plate inside the cavity, and the limiting piston rod is slidably installed inside the limiting sleeve.

[0007] Preferably, a resistance spring is connected between the top outer wall of the limiting piston rod and the top inner wall of the limiting sleeve, and the extended end of the limiting piston rod is arranged below the limiting sleeve.

[0008] Preferably, the extended end of the limiting piston rod is connected to the top outer wall of the abutment plate, and the abutment plate is arranged in an "I" shape.

[0009] Preferably, the upper half of the abutment plate is slidably mounted inside the upper pressing plate, and the lower half of the abutment plate is arranged outside the upper pressing plate.

[0010] Preferably, the reinforcement support mechanism comprises a mounting column and a threaded groove, the bottom outer wall of the position-limiting support block is provided with a mounting column, and the bottom outer wall of the mounting column is provided with a threaded groove.

[0011] Preferably, the internal threads of the thread groove are provided with a positioning thread column, and the outer wall of the bottom end of the positioning thread column is provided with a ground nail.

[0012] The beneficial effects of the utility model are:

[0013] 1. When the geogrid quick assembly buckle is in use, the limit sleeve, the limit piston rod, the resistance spring and the resistance plate are set, and the spring is used to generate a reaction force when it is squeezed. On the one hand, the resistance plate can always resist the outer wall of the lower pressing plate, thereby ensuring that the geogrid can always be pressed in the middle position by the resistance plate and the lower pressing plate, thereby avoiding the phenomenon that the geogrid can still move after installation. On the other hand, the reaction force of the spring is used to reversely push the setting of the matching structure transmission, so that the positioning support block can directly resist the nut block, so that the nut block is not easy to fall off through the effect of resistance support. The overall structural design is ingenious and has good practical effect.

[0014] 2. When the geogrid quick assembly buckle is in use, the ground nails are set so that the device can use the ground nails to drive into the soil layer to further limit the support of the fastener as a whole when installing the geogrid. The fastener is locked in position to ensure that the geogrid will not be easily offset after installation. With the detachable design of the ground nails, suitable ground nails can be selected for installation support according to different ground conditions. The overall flexibility is good and the practical effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] When implementing: Figure 1-4As shown, a geogrid quick assembly buckle includes an upper pressed plate member 1 and a lower pressed plate member 2: the upper pressed plate member 1 is located above the lower pressed plate member 2, a portable installation mechanism 3 is connected between the upper pressed plate member 1 and the lower pressed plate member 2, a resistance support mechanism 4 is arranged inside the upper pressed plate member 1, and a reinforcement support mechanism 5 is arranged on the side of the lower pressed plate member 2. The portable installation mechanism 3 includes a limit support block 31, a limit threaded column 32, a positioning support block 33, a placement hole 34 and a nut block 35. Two groups of limit support blocks 31 are symmetrically arranged on the outer walls of both sides of the lower pressed plate member 2, and the top outer wall of the limit support block 31 is provided with a limit threaded column 32. The outer walls of both sides of the upper pressed plate member 1 are symmetrically provided with two groups of limit support blocks 31. The support block 33 is positioned, and a placement hole 34 is formed on the top outer wall of the positioning support block 33. The diameter of the limiting threaded column 32 is smaller than the diameter of the placement hole 34. A nut block 35 is fitted on the top outer wall of the positioning support block 33, and a threaded installation is performed between the nut block 35 and the limiting threaded column 32. When the upper and lower pressed plates 1 and 2 need to be installed together, it is only necessary to adjust the limiting threaded column 32 to a suitable position and pass it through the placement hole 34 at the corresponding position, and then screw the nut block 35 from top to bottom to the outside of the limiting threaded column 32. It is noted here that the standard for tightening the nut block 35 is until it can no longer be twisted. At this point, the combined installation of the upper and lower pressed plates 1 and 2 is completed, and the disassembly is the same.

[0022] The resistance support mechanism 4 includes a limiting sleeve 41 and a limiting piston rod 42. The interior of the upper pressed plate 1 is set as a cavity structure, and the limiting sleeves 41 are arranged at equal intervals on the top inner wall of the upper pressed plate 1 located inside the cavity. The limiting piston rod 42 is slidably installed inside the limiting sleeve 41. A resistance spring 43 is connected between the top outer wall of the limiting piston rod 42 and the top inner wall of the limiting sleeve 41. The protruding end of the limiting piston rod 42 is set below the limiting sleeve 41. The protruding end of the limiting piston rod 42 is connected to the top outer wall of the resistance plate 44. The resistance plate 44 is set in an "I" shape. The upper half of the resistance plate 44 is slidably installed inside the upper pressed plate 1 The lower half of the contact plate 44 is arranged on the outside of the upper pressed plate 1; when the upper pressed plate 1 and the lower pressed plate 2 are fitted together during the installation process, the contact plate 44 is automatically moved upward by the extrusion, and then the upward displacement of the contact plate 44 will automatically drive the limiting piston rod 42 to slide inside the limiting sleeve 41. At this time, the contact spring 43 is squeezed by the contact plate 44 and is in a contracted state. At the same time, the contact spring 43 is squeezed by the extrusion force and generates a reaction force to push the limiting piston rod 42 to move downward, and then the downward displacement of the limiting piston rod 42 automatically drives the contact plate 44 to move downward, so that the contact plate 44 can always fit with the top outer wall of the lower pressed plate 2.

[0023] The reinforcement support mechanism 5 includes a mounting column 51 and a threaded groove 52. The bottom outer wall of the limiting support block 31 is provided with a mounting column 51, and the bottom outer wall of the mounting column 51 is provided with a threaded groove 52. The internal thread of the threaded groove 52 is installed with a positioning threaded column 53, and the bottom outer wall of the positioning threaded column 53 is provided with a ground nail 54; the setting of the ground nail 54 here enables it to be nailed into the inside of the soil layer to achieve the effect of reinforcement support. When it is necessary to install the ground nail 54 of a suitable length according to the soil conditions, at this time, it is only necessary to screw the positioning threaded column 53 into the corresponding position of the threaded groove 52 in turn to complete the installation of the ground nail 54, and the disassembly is similar. The mounting column 51 here plays an auxiliary limiting effect on the threaded groove 52.

[0024] When the utility model is in use, the device first needs to pave the two geogrids according to the existing technical standards, and then it is necessary to select the ground nails 54 of appropriate length according to the hardness difference of the soil layer. When replacing the ground nails 54, it is only necessary to screw the positioning threaded columns 53 into the corresponding positions of the threaded grooves 52 in sequence to complete the installation of the ground nails 54. The same is true for disassembly. After the two geogrids are paved, the lower pressing plate 2 needs to be placed at the connection between the two geogrids. Note that the lower pressing plate 2 needs to be located below the geogrid. After adjusting the appropriate position, the ground nails 54 are driven into the soil layer. Note that the limiting threaded column 32 Four are provided, which are divided into two groups during installation. The two limiting threaded columns 32 in the same group need to be located inside the grid of the same geogrid, and then the upper pressed plate 1 is installed above the lower pressed plate 2. It is noted that the geogrid is located in the middle of the upper pressed plate 1 and the lower pressed plate 2. During installation, it is only necessary to adjust the limiting threaded column 32 to a suitable position and pass it through the placement hole 34 at the corresponding position, and then screw the nut block 35 from top to bottom to the outside of the limiting threaded column 32. It is noted that the standard for tightening the nut block 35 is until it cannot be twisted. At this point, the combined installation of the upper pressed plate 1 and the lower pressed plate 2 is completed;

[0025] When the upper and lower compression plates 1 and 2 are fitted together during installation, the contact plate 44 is automatically moved upward by the extrusion, and the upward movement of the contact plate 44 will automatically drive the limit piston rod 42 to slide inside the limit sleeve 41. At this time, the contact spring 43 is squeezed by the contact plate 44 and is in a contracted state. At the same time, the contact spring 43 is squeezed and generates a reaction force to push the limit piston rod 42 downward. Then, the downward movement of the limit piston rod 42 automatically drives the contact plate 44 downward, so that the contact plate 44 can always fit the top outer wall of the lower compression plate 2. When the above-mentioned nut block 35 no longer rotates, the reaction force of the contact spring 43 will push the upper compression plate 1 upward through the mechanism transmission, thereby preventing the contact thread from falling off.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
