[0015] Depend on Figure 1-4Provided is a protective guardrail for outdoor engineering construction, comprising two bottom plates 1, the tops of the two bottom plates 1 are respectively provided with extension components 2, the extension components 2 include a sleeve frame 21 and a telescopic frame 22, the sleeve frame 21 has a shell structure, the upper part of the sleeve frame 21 is open, the bottom of the sleeve frame 21 is fixedly connected to the top of the bottom plate 1, the bottom end of the telescopic frame 22 enters into the sleeve frame 21 from the top wall of the sleeve frame 21, the telescopic frame 22 and the sleeve frame 21 are slidably matched, a slide groove 23 is provided on one side wall of the sleeve frame 21, a limit axis 24 is fixedly connected to the bottom of one side of the telescopic frame 22, the limit axis 24 slides through the slide groove 23, a fixed screw rod 25 is provided on the upper part of one side wall of the sleeve frame 21, the screw rod 25 is on the same side as the limit axis 24, one end of the fixed screw rod 25 penetrates the sleeve frame 21, the fixed screw rod 25 is threadedly connected to the sleeve frame 21, and one end of the fixed screw rod 25 is tightly against the outer wall of the telescopic frame 22;

[0016] Limiting grooves 3 are respectively provided on the outer walls on the opposite sides of the two telescopic frames 22, and the two telescopic frames 22 are connected by a connecting component 4. A sleeve plate 5 is fixedly connected to the front of the left sleeve frame 21, and an insert plate 6 is fixedly connected to the front of the right sleeve frame 21. The left end of the insert plate 6 penetrates the right side wall of the sleeve plate 5 and enters the interior of the sleeve plate 5, and the insert plate 6 slides with the sleeve plate 5.

[0017] The connecting assembly 4 includes two slide bars 41, and the two slide bars 41 are respectively fixedly connected to the inside of the two limit grooves 3. The ends of the slide bars 41 are fixedly connected to the inner wall of the limit groove 3. The outer wall of the slide bar 41 is clearance-matched with the inner wall of the limit groove 3. The outer wall of the slide bar 41 is slidably sleeved with a slide sleeve 42. The outer walls of the two slide sleeves 42 on the opposite sides are respectively provided with a hinge seat 1 43 and a fixed screw 2 44. The hinge seat 1 43 is fixedly connected to the slide sleeve 42. The fixed screw 2 44 penetrates the slide sleeve 42. The fixed screw 2 44 4 is threadedly connected with the sliding sleeve 42, one end of the fixing screw rod 24 is tightly pressed against the outer wall of the sliding rod 41, and the upper parts of the opposite sides of the two telescopic frames 22 are respectively fixedly connected with hinge seats 25, and the two hinge seats 25 and the two hinge seats 1 43 are respectively rotatably connected with the upper and lower shafts 7 at one end of the scissor-type scissors frame 46, and the upper and lower ends of one side of the scissor-type scissors frame 46 are respectively provided with shafts 7, and the shafts 7 penetrate the upper and lower ends of one side of the scissor-type scissors frame 46, and the shafts 7 are fixedly connected with the upper and lower ends of one side of the scissor-type scissors frame 46.

[0018] The utility model provides a protective guardrail for outdoor engineering construction. When the horizontal dimension of the guardrail needs to be adjusted, the distance between the two sleeve frames 21 can be directly expanded or contracted to the left and right sides, so that the scissor frame 46 can be expanded or contracted accordingly. At the same time, the lower hinge seat 43 moves with the scissor frame 46 and drives the sliding sleeve 42 to slide on the outer wall of the sliding rod 41, and the plug plate 6 follows the sliding inside the sleeve 5. After the above steps, the horizontal dimension of the interception of the protective guardrail is changed. After the horizontal dimension is adjusted, the current state of the scissor frame 46 can be adjusted by screwing the fixing screw 44 until it contacts the sliding rod 41. It can be fixed to keep its current horizontal dimension. However, when the vertical dimension of the guardrail needs to be adjusted, the telescopic frame 22 can be pulled upward to slide inside the sleeve frame 21. During this process, the scissor frame 46 extends on the back of the sleeve plate 5 and the plug plate 6, thereby changing the intercepting vertical dimension of the protective guardrail. After adjustment, the fixing screw 25 can be screwed to maintain the current state between the telescopic frame 22 and the sleeve frame 21. The design of adjustable horizontal and vertical dimensions of the protective guardrail can not only meet the different needs of users, but also adjust the size area to the minimum state during transportation, so as to achieve the effect of easy handling.
