Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A combined safety guardrail comprises a guardrail body 1, a first connecting block 2 is connected to one side of the guardrail body 1, a second connecting block 3 is connected to the other side of the guardrail body 1, a slot hole 4 is provided inside the first connecting block 2, and a threaded rod 5 is connected to the inside of the slot hole 4 through a bearing, a bevel gear set 6 is sleeved at the center of the threaded rod 5, and a rotating shaft 7 is inserted at the front end of the bevel gear set 6, two sets of external threads with opposite rotation directions are symmetrically provided at the upper and lower ends of the threaded rod 5, and an internal thread matched with the threaded rod 5 is provided inside the movable plate 9, so that when the threaded rod 5 rotates, it can bring The two groups of movable plates 9 are moved in opposite directions inside the slot 4. The bevel gear set 6 is composed of two groups of bevel gears, which are fixedly sleeved on the outside of the threaded rod 5 and the rotating shaft 7 respectively, and the rotating shaft 7 is inserted in the first connecting block 2 through a bearing. Therefore, when the rotating shaft 7 rotates, the threaded rod 5 can be driven to reverse and rotate. The rotating shaft 7 extends to the outside of the first connecting block 2. The upper and lower ends of the threaded rod 5 are symmetrically sleeved with movable plates 9, and the side of the movable plates 9 that is away from each other is connected to the limit block 11 through the connecting rod 10, and the second connecting block 3 is provided with a slot adapted to the limit block 11.

[0023] Further, see Figure 2 and Figure 4 It can be known that the front of the rotating shaft 7 is connected with a rotating block 8, and the outer surface of the rotating block 8 is evenly connected with rotating sheets. When in use, the rotating shaft 7 can be driven to rotate simultaneously through the connection of the rotating block 8.

[0024] Further, see Figure 3 It can be known that the side of the second connecting block 3 is connected to a fixing plate 12, and an insertion strip 13 is inserted inside the fixing plate 12, and a linkage plate 14 is provided at the bottom end of the insertion strip 13. When in use, the reinforcement operation of the guardrail body 1 can be achieved through the connection between the fixing plate 12 and the linkage plate 14, so as to preliminarily ensure the stability of the device during placement.

[0025] Further, see Figure 1 and Figure 3 It can be known that support rods 15 are equidistantly distributed at the bottom end of the linkage plate 14, and the support rods 15 are arranged in a conical structure. When in use, the support rods 15 arranged in a conical structure can be inserted into the ground of the construction site, thereby further improving the stability of the device when placed.

[0026] Further, see Figure 3It can be known that the upper side of the linkage plate 14 is symmetrically connected with a sleeve rod 16, and the sleeve rod 16 is sleeved on the bottom end of the insertion strip 13, and the interior of the sleeve rod 16 is connected to the insertion strip 13 by bolts. When in use, the insertion strip 13 and the linkage plate 14 can be disassembled and assembled by the cooperation of the sleeve rod 16 and the bolts, so as to reduce the floor space of the device, thereby facilitating the staff to transport and store the device.

[0027] Further, see Figure 3 It can be seen that the fixing plates 12 are symmetrically distributed at the front and rear ends of the second connecting block 3, and the insertion strips 13 are arranged as a U-shaped structure. The insertion strips 13 arranged through the U-shaped structure and the arrangement of two groups of fixing plates 12 can effectively improve the stability of the insertion strips 13 when inserted into the fixing plates 12.

The rubber sleeves are not shown in the figure. The rubber sleeves provided on the outer sides of the limit blocks 11 can effectively ensure the tightness of the limit blocks 11 when inserted into the slots inside the second connecting block 3, so as to effectively ensure the reliability of the connection process between the guardrail bodies 1.

[0029] Working principle: When the utility model is used, the staff can first bring the guardrail bodies 1 to be connected close to each other, and then insert the first connecting block 2 connected to the side of the guardrail body 1 into the second connecting block 3 connected to the side of another group of guardrail bodies 1. Then the staff can manually rotate the rotating block 8, thereby driving the rotating shaft 7 to rotate at the same time. Since the rotating shaft 7 is inserted into the inside of the bevel gear set 6, it can drive the threaded rod 5 to rotate in the opposite direction. Since the upper and lower ends of the threaded rod 5 are symmetrically provided with two groups of external threads with opposite rotation directions, the two groups of moving plates 9 can move in opposite directions inside the slot 4, so that The two groups of limit blocks 11 are embedded in the slots opened inside the second connecting block 3 to realize the connection operation between the first connecting block 2 and the second connecting block 3. Then the staff can insert the insertion bar 13 into the two groups of fixed plates 12, and connect the sleeve rod 16 and the insertion bar 13 by bolts to install the linkage plate 14 and the support rod 15 at the bottom end of the insertion bar 13. Then the staff can press down the insertion bar 13 to make the support rod 15 set in the conical structure embedded in the ground, thereby effectively improving the stability of the guardrail body 1 during use. The above is the entire working principle of the utility model.
