DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 of the embodiments.
[0019] Embodiment 1: Refer to Figures 1-4 , a municipal foundation pit protection fence, including a fence 1. Socket seats 2 are fixedly installed on both sides of the fence 1. A plug rod 3 is inserted into the socket seat 2. A fixing rod 4 is fixedly installed at the end of the plug rod 3. The plug rod 3 can be inserted into the socket seat 2, which is convenient for installing and connecting the fixing rod 4 and the fence 1, and the disassembly is also convenient. During use, in order to prevent the plug rod 3 from disengaging from the socket seat 2, it can be restricted by screwing a nut on the end of the plug rod 3, so that the plug rod 3 and the socket seat 2 will not disengage. In addition, the angle between the plug rod 3 and the socket seat 2 can be adjusted, and the angle of the fence can be adjusted according to the specific shape of the foundation pit. The state shown in the attached drawing is that the included angle between the fence 1 and the telescopic fence 5 is 180°.
[0020] A telescopic fence 5 is rotatably connected to one side of the fixing rod 4. The shape of the telescopic fence 5 is as shown in the attached drawing. The telescopic fence 5 can be telescoped and its length can be adjusted. An activity rod 6 is rotatably connected to the end of the telescopic fence 5 away from the fixing rod 4. Matching mechanisms are also rotatably connected to both ends of the telescopic fence 5. The matching mechanisms are respectively slidably arranged on one side of the fixing rod 4 and the activity rod 6. The matching mechanism is mainly used to ensure that the telescopic fence 5 can be telescopically stable. A screwing ear 14 is fixedly installed on one side of the activity rod 6. The screwing ears 14 are fixedly connected by bolts. The screwing ears 14 are convenient for disassembly and assembly, and it is convenient to disassemble and assemble the activity rods 6. Because the telescopic fence 5 and the fence 1 are arranged at intervals, it is convenient to adjust the length of the fence. In addition, if a door body for transporting engineering materials needs to be specially set up, multiple telescopic fences 5 can be connected by screwing ears 14 between the activity rods 6 to act as the door body. When the telescopic fence 5 is fully extended, the door body is closed; if the door body needs to be opened, the bolts between the screwing ears 14 need to be removed, and then the telescopic fence 5 can be retracted to one side to facilitate the transportation of materials.
[0021] The matching mechanism includes a coupling seat 9. A slider 8 is fixedly installed at the end of the coupling seat 9. Sliding grooves 7 are opened on the sides of the fixing rod 4 and the activity rod 6. The slider 8 is slidably arranged in the sliding groove 7. The coupling seat 9 is slidably arranged in the sliding groove 7 through the slider 8. Matching protrusions 16 are also fixedly installed on both sides of the slider 8. A strip-shaped groove 15 is opened on the side wall of the sliding groove 7. The matching protrusion 16 is slidably arranged in the strip-shaped groove 15. The matching protrusion 16 can prevent the slider 8 from disengaging from the sliding groove 7. The sliding groove 7, the strip-shaped groove 15, the fixing rod 4 and the activity rod 6 are the same in length direction. The fixing rod 4, the telescopic fence 5 and the activity rod 6 are located in the same vertical plane. When the telescopic fence 5 extends and retracts, the end of the telescopic fence 5 connected to the coupling seat 9 will move up and down, which will drive the coupling seat 9 to move up and down. The movement of the coupling seat 9 will drive the slider 8 to slide in the sliding groove 7, so that the telescopic fence 5 can be stable during the telescopic process.
[0022] The outer surface of the lower end of the fixed rod 4 is threadedly sleeved with a stabilizing mechanism. The stabilizing mechanism is inserted into the soil. The stabilizing mechanism includes a base 12. The cross-section of the base 12 is square-shaped, and the lower end of the base 12 is in a pointed shape. The base 12 is inserted into the soil. The base 12 inserted into the soil has good stability. An activity cavity 13 is opened inside the upper end of the base 12. A limiting block 11 is slidably arranged inside the activity cavity 13. The cross-sections of the limiting block 11 and the activity cavity 13 are both circular-shaped, so that the limiting block 11 can rotate inside the activity cavity 13. A sleeve block 10 is fixedly installed at the upper end of the limiting block 11. The upper end of the sleeve block 10 extends through above the base 12. The upper end of the sleeve block 10 is threadedly sleeved on the outer side of the fixed rod 4. After the sleeve block 10 is connected to the fixed rod 4, under the action of the base 12, the fixed rod 4 is not easily inclined and has high stability.
[0023] Place the fence 1 on the soil at the designated position. According to the position of the fixed rod 4, hammer the base 12 into the soil. Then, pull up the sleeve block 10 and make it contact with the bottom of the fixed rod 4. Rotate the sleeve block 10 and sleeve it on the outer side of the end of the fixed rod 4. The stability of the fixed rod 4 can be improved through the base 12, thereby improving the overall stability of the guardrail. In addition, the rotation sleeve block 10 and the fixed rod 4 are convenient to disassemble, and the guardrail can be conveniently removed or adjusted in position.
[0024] Working principle: During the installation process of this municipal foundation pit guardrail, first connect the fence 1 and the fixed rod 4 together through the insertion rod 3 and the socket 2. Adjust the angle between the fence 1 and the telescopic fence 5 according to the shape of the foundation pit. Then, hammer the base 12 into the soil below the fixed rod 12. Pick up the sleeve block 10 and connect it to the lower end of the fixed rod 4, which can improve the overall stability of the guardrail. Then, pull the telescopic fence 5 to extend. The extension of the telescopic fence 5 will drive the connecting shaft seat 9 to move downward. The connecting shaft seat 9 will drive the slider 8 to slide downward to maintain the stability of the extension of the telescopic fence 5. Connect the movable rod 6 to another movable rod 6 connected with the telescopic fence 5 through bolts. In this way, the installation is completed by cycling. The length of this guardrail is convenient to adjust. Doors can be set by connecting several groups of telescopic fences 5, which can conveniently provide space for transporting materials.
[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
