DETAILED DESCRIPTION
[0024] Embodiment 1
[0025] As shown in the figure, the utility model proposes an assembled retaining wall, comprising a baffle 1, a connecting column 3, a sliding rod 4 and an adjustment assembly. A through hole 101 is provided on the baffle 1, and a reinforcing rib 102 is provided in the through hole 101. A mounting plate 103 is provided on the baffle 1, and the sides of the two mounting plates 103 that are away from each other are flush with the end faces of the corresponding sides of the baffle 1, and a mounting hole is provided on the mounting plate 103. Ear plates 2 are provided on both sides of the baffle 1, and tooth grooves 201 are symmetrically provided on the ear plates 2. A card groove is provided on both sides of the connecting column 3, and the ear plate 2 is inserted into one of the card grooves on one side and slidably connected thereto. The upper and lower groups of sliding rods 4 are both slidably connected to the connecting column 3, and the upper and lower groups of sliding rods 4 are both provided with limit teeth 5 at the ends close to each other. A receiving groove 301 for recovering the sliding rod 4 and the limit teeth 5 is provided on the connecting column 3. The length of the sliding rod 4 is greater than the depth of the tooth groove 201. The adjustment assembly is connected to the connecting column 3 and drives the slide bars 4 to insert the slide bars 4 into the tooth grooves 201 on the corresponding side ear plates 2 after the ear plates 2 are inserted into the slots and the angle between the baffle plate 1 and the connecting column 3 is limited by the limiting teeth 5. The adjustment assembly includes a slider 6 and a bidirectional screw 7, the slider 6 is connected to the slide bar 4, the slider 6 is slidably connected to the connecting column 3, the bidirectional screw 7 is rotatably connected to the connecting column 3, and the upper and lower sets of sliders 6 are respectively spirally connected to the corresponding ends of the bidirectional screw 7.
[0026] In this embodiment, when assembling, first fix the connecting column 3, then take a baffle 1, insert the ear plate 2 on one side of the baffle 1 into the slot on the corresponding side of the current connecting column 3, adjust the angle between the ear plate 2 and the connecting column 3, and after the angle is adjusted, use a tool to drive the bidirectional screw 7 to rotate. During the rotation of the bidirectional screw 7, the sliders 6 on both sides approach each other, and the sliders 6 drive the slide bar 4 to approach each other and respectively snap into the corresponding side tooth grooves 201 on the current ear plate 2. The limiting teeth 5 engage with the tooth grooves 201 to lock the angle relationship between the current baffle 1 and the connecting column 3. Since the length of the slide bar 4 is greater than the depth of the tooth groove 201, there is still a section of the slide bar 4 located in the connecting column 3. Through the dual limiting of the connecting column 3 and the slider 6, the impact resistance of the slide bar 4 is improved to prevent it from being easily bent under the impact of external forces. Then continue to connect and fix each baffle 1 and the connecting column 3 in turn according to the operation steps.
[0027] Embodiment 2
[0028] like Figure 1 and Figure 2 As shown, the utility model proposes an assembled retaining wall. Compared with the first embodiment, a plug rod 104 is provided at the top of the baffle 1, and a plug hole 105 is provided at the bottom of the baffle 1. The depth of the plug hole 105 is not less than the length of the plug rod 104.
[0029] In this embodiment, when the height of a single-layer baffle 1 is insufficient, an additional layer is installed on the current baffle 1. When installing, the bottom socket 105 of the newly added baffle 1 is aligned with the plug rod 104 at the top of the current baffle 1, and then the newly added baffle 1 is pressed down until it fits with the current baffle 1. By stacking the layers of the structure, the device can be adapted to different height requirements, and the assembly is simple and convenient.
[0030] Embodiment 3
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, the utility model proposes an assembled retaining wall. Compared with the first embodiment, the bidirectional screw 7 is connected to the worm wheel 8, the connecting column 3 is rotatably connected to the worm 9, and the worm 9 is meshedly connected with the worm wheel 8.
[0032] In this embodiment, by driving the worm 9 to rotate, the worm wheel 8 and the bidirectional screw 7 are driven to rotate, so that the bidirectional screw 7 can be prevented from rotating under force when the baffle 1 is impacted, thereby further improving the stability of the entire device.
[0033] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
