DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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] like Figures 1 to 5 As shown, an alarm device that is easy to replace for use at a construction site includes a mounting rod 1, a positioning mechanism, a mounting mechanism, and an alarm device body 2. The positioning mechanism is arranged at the bottom of the mounting rod 1 for positioning;

[0022] The mounting mechanism includes a mounting frame 3, a mounting block 4, a pressing cylinder 5 and a clamping block 6; the mounting frame 3 is arranged on the top of the mounting rod 1, and clamping grooves 31 are provided on the side walls on both sides of the mounting frame 3; the mounting block 4 is arranged at the bottom of the alarm device body 2; clamping blocks 6 are arranged on both sides of the mounting block 4, and the size of the clamping blocks 6 is adapted to the clamping groove 31; by adapting the size of the clamping block 6 to the clamping groove 31, it is convenient to set the alarm device body 2 in the pressing frame.

[0023] The end of the clamping block 6 located inside the mounting block 4 is connected to an adjustment frame 61, and the adjustment frame 61 is hingedly arranged on the fixing plate 51; the end of the pressing cylinder 5 inserted into the mounting block 4 is connected to the fixing plate 51, and the other end is arranged outside the mounting block 4; a spring 7 is arranged between the fixing plate 51 and the inner wall of the mounting block 4, and a fixing rod 71 is arranged on the inner circle of the spring 7, and one end of the fixing rod 71 is fixedly connected to the inner wall of the mounting block 4, and the other end extends into the pressing cylinder 5.

[0024] By pressing the pressing cylinder 5, the pressure of the fixed block acts on the spring 7, and the elastic force of the spring 7 drives the fixed block to move. The adjustment frame 61 on both sides of the fixed block drives the clamping blocks 6 on both sides to slide and shrink along the inside of the mounting block 4, so that the clamping blocks 6 on both sides are separated from the clamping slot 31 and the limit is released; it is convenient to disassemble the alarm device body 2 on the mounting frame 3. At the same time, when the pressing cylinder 5 is loosened, the reverse force of the spring 7 drives the fixed block to reset, and the hinged adjustment frame 61 drives the clamping blocks 6 on both sides to extend outward from the mounting block 4 to achieve locking, wherein the oblique edges of the clamping blocks 6 on both sides are set downward, which is convenient for installation and disassembly, and improves the efficiency of replacing the alarm device body 2.

[0025] The mounting rod 1 can rotate; the positioning mechanism includes a fixed frame 8, a connecting block 9, a connecting frame 91 and a supporting plate 92; the fixing frame 8 is arranged on the mounting rod 1, and through slots 81 are provided on both sides of the fixing frame 8; the connecting block 9 is fixedly arranged on the mounting rod 1, the connecting frame 91 is hingedly arranged at both ends of the connecting block 9, the other end of the connecting frame 91 is hingedly arranged with the supporting plate 92, one end of the supporting plate 92 is arranged in the through slot 81, and is rotatably arranged with the fixing frame 8. The mounting rod 1 is provided with a handle 11, and the handle 11 is located above the fixing frame 8; the bottom of the mounting rod 1 is provided with a spiral cone 12.

[0026] By turning the handle 11, the installation rod 1 is driven to rotate so that the spiral cone 12 rotates, and the spiral cone 12 rotates into the soil, which facilitates the installation of the installation rod 1, and there is no need to dig a pit in advance, and the installation efficiency is high. At the same time, when the installation rod 1 moves downward, the support plates 92 on both sides are driven to open through the connecting block 9 and the connecting frames 91 on both sides, and the downward movement range of the spiral cone 12 is limited by the support plates 92, and it can play a certain supporting role on the spiral cone 12, preventing the spiral cone 12 from separating from the ground, and when not in use, it is convenient to store it in the through groove 81 as a whole for storage, thereby improving space utilization.

[0027] The pressing cylinder 5 is provided with a limiting block 52 , which is arranged inside the mounting block 4 and is used to limit the pressing cylinder 5 .

[0028] The limiting block 52 is provided to play a limiting role and prevent the pressing cylinder 5 from being separated from the mounting block 4.

[0029] The working principle of the utility model is as follows: align the mounting block 4 at the bottom of the alarm device body 2 with the mounting frame 3 at the top of the mounting rod 1, and ensure that the clamping blocks 6 on both sides of the mounting block 4 correspond to the clamping slots 31 in the mounting frame 3. Under the guidance of the oblique edges of the clamping block 6, the clamping block 6 is pushed in along the direction of the clamping slot 31, and at this time, the clamping block 6 is restricted by the clamping slot 31 and gradually shrinks. When the clamping block 6 completely enters the clamping slot 31, due to the reverse force of the spring 7, the fixed block is reset, and the clamping block 6 is driven to extend outward through the adjustment frame 61, thereby being locked in the mounting frame 3.

[0030] When removing the alarm device body 2, the pressing cylinder 5 on the outside of the mounting block 4 is pressed to apply pressure to the fixing block and compress the spring 7. During the compression of the spring 7, the adjustment brackets 61 on both sides of the fixing block drive the clamping block 6 to slide and contract along the inside of the mounting block 4, so that the clamping block 6 is separated from the clamping slot 31. When the clamping block 6 is completely separated from the clamping slot 31, the alarm device body 2 can be easily removed from the mounting frame 3.

[0031] During the positioning of the mounting rod 1, the mounting rod 1 is rotated by turning the handle 11, thereby driving the spiral cone 12 to rotate into the soil. During the downward movement of the mounting rod 1, the connecting block 9 drives the support plate 92 to open outward through the connecting frames 91 on both sides, and the support plate 92 rotates and locks in the through slot 81 of the fixing frame 8, thereby supporting the spiral cone 12.

[0032] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
