[0002] In air conditioning installation projects, especially in the installation of outdoor units around windows in high-rise buildings, mobile safety protection devices serve as core protective equipment. They play an important role in building safety barriers in temporary work areas and preventing personnel from falling. Their adaptability and protective integrity are directly related to construction safety and work efficiency. The structural rationality of the device is related to the installation stability in different environments. If the protective structure is missing, it will lead to protection failure and thus cause safety risks.

[0003] Traditional safety devices often rely on ropes or mobile safety devices to protect workers. However, ropes are prone to slack under prolonged loads, and mobile safety devices can cause workers to lose their balance or fall when leaning against them. Furthermore, blind spots can easily appear when workers move or bend over to operate, making it difficult to form an effective safety barrier and resulting in insufficient safety. In addition, the structures where safety devices are fixed to the wall often require manual insertion and removal or adjustment with bolts, which is not only cumbersome but also has a limited range of adjustment. This makes it difficult to flexibly adapt to the thickness of windows and walls in different buildings, resulting in gaps between the device and the wall after installation, affecting the stability of the installation and the reliability of the protection.

[0004] Therefore, a mobile safety protection device for air conditioning installation projects is proposed to solve the above problems. Utility Model Content

As the main connecting component of the latch assembly 4, the connecting plate 47 is disposed on the right surface of the frame 1. A buckle plate 49 is fixedly connected to the left surface of the connecting plate 47. Two sets of buckle plates 49 are L-shaped and are fixed horizontally and vertically to the front and rear sides of the connecting plate 47. A sliding groove 46 is formed through the right surface of the connecting plate 47. A rotating shaft 45 is fixedly connected to the inner wall of the sliding groove 46. The rotating shaft 45 is a cylindrical shaft, horizontally fixed within the sliding groove 46, with its other end... The rotating shaft 45 is rotatably connected to the inner wall of the guardrail 5. A slot 44 is provided on the right section of the outer wall of the rotating shaft 45. The slot 44 is a concave groove on the outer wall of the rotating shaft 45, used to cooperate with the movable block 43 to restrict the rotation of the rotating shaft 45, thereby fixing the guardrail 5. The inner wall of the top of the guardrail 5 is elastically connected to the movable block 43 via a compression spring 42. The movable block 43 is a rectangular block that can slide up and down on the inner wall of the upper surface of the guardrail 5. Its lower end can be engaged in the slot 44 to lock the rotating shaft 45. A pull rod 41 is fixedly connected to the upper surface of the movable block 43. The pull rod 41 is vertical. A metal rod fixed to the upper surface of the movable block 43 passes through the compression spring 42 and the upper surface of the guardrail 5, facilitating manual lifting of the movable block 43 by the operator to release its engagement with the slot 44. A fixing groove 48 is provided through the right surface of the frame 1. The fixing groove 48 is a circular groove on the right surface of the frame 1, and its diameter is adapted to the rotating shaft 45. The outer surface of the pull rod 41 passes through and slides on the upper surface of the guardrail 5.

[0035] Reference Figures 1-3The telescopic component 3 includes a fixed column 32, which is a hollow rectangular tube. Its right end is fixedly connected to the left surface of the frame 1, serving as a housing and guide for the sliding rod 31. The right end of the fixed column 32 is fixedly connected to the left surface of the frame 1. The sliding rod 31 is slidably connected through the left surface of the fixed column 32. A support rod 2 is fixedly connected to the left surface of the sliding rod 31. The right end of the sliding rod 31 slides within the fixed column 32 and can slide axially along the fixed column 32. Its extension and retraction change the length of the left end of the device. A threaded rod 33 is threadedly connected to the inner wall of the sliding rod 31. The threaded rod 33 is horizontally positioned inside the fixed column 32, with its left end threaded into the inner wall of the sliding rod 31. Its rotation drives the sliding rod 31 to extend and retract within the fixed column 32. The right end of the threaded rod 33 is fixedly connected to… A bevel gear 34 is attached to the right end of the threaded rod 33 and meshes with a second bevel gear 35 to transmit the rotation of the rotating rod 36 to the threaded rod 33. The front surface of the first bevel gear 34 meshes with the second bevel gear 35, which is fixed to the rotating rod 36 and meshes perpendicularly with the first bevel gear 34, thus changing the direction of rotation and converting the lateral rotation of the rotating rod 36 into the longitudinal rotation of the threaded rod 33. The inner wall of the second bevel gear 35 penetrates and is fixedly connected to the rotating rod 36. The rotating rod 36 passes through the right section of both sets of fixed posts 32, synchronously driving the two sets of second bevel gears 35 to rotate, achieving synchronous adjustment of the two sets of telescopic components 3. A turntable 37, a circular disc, is fixedly connected to the front end of the rotating rod 36. The front end of the lever 36 increases the rotation radius, making it easier for the operator to rotate the lever 36. A handle 38 is slidably connected to the inner surface of the turntable 37 away from the center. The handle 38 is a cylindrical rod that passes through the turntable 37, and its rear end can be inserted into the circular groove 311 to lock the position of the turntable 37 and facilitate hand rotation of the turntable 37. The rear surface of the turntable 37 is connected by a telescopic spring 39, which is sleeved on the handle 38. The two ends of the spring are connected to the rear surface of the turntable 37 and the front surface of the fixing ring 310, respectively, providing a backward pulling force to the handle 38 and ensuring that the rear end of the handle 38 can be tightly inserted into the circular groove 311. The fixing ring 310 is elastically connected to the handle 38. The fixing ring 310 is a circular ring that is sleeved on the rear part of the outer surface of the handle 38. The right part of the front surface of the fixing post 32 is opened. A circular groove 311 is provided, which is a circular groove formed on the front surface of the fixed column 32 and distributed along the circumference of the fixed column 32. The handle 38 is inserted into the groove to restrict the rotation of the turntable 37. The support rod 2, sliding rod 31, fixed column 32, threaded rod 33, bevel gear 1 34, and bevel gear 2 35 are provided in two sets, evenly distributed on the front and rear sections of the left surface of the frame 1. The two sets of symmetrically distributed components make the left end of the frame 1 evenly stressed, improving the stability of the device after telescopic adjustment. The rotating rod 36 passes through and is rotatably connected to the front surface of the fixed column 32. The passage of the rotating rod 36 and the fixed column 32 is a rotatable fit, ensuring that the rotating rod 36 can rotate flexibly while ensuring its position is stable. The threaded rod 33 is rotatably connected to the inner wall of the fixed column 32.The retaining ring 310 is fixed to the rear section of the outer surface of the handle 38. The rear end of the handle 38 is inserted into the inner wall of the circular groove 311. By cooperating with the handle 38 and the circular grooves 311 at different angles, the length of the telescopic component 3 is fixed.

[0036] Working principle: In use, first adjust the telescopic component 3 according to the thickness of the window wall. At this time, pull the handle 38 forward, the fixing ring 310 compresses the telescopic spring 39, and the handle 38 will disengage from the circular groove 311 of the fixing post 32, releasing the lock of the turntable 37. Then rotate the handle 38, the rotating rod 36 drives the second bevel gear 35 to rotate, and the first bevel gear 34 meshing with the second bevel gear 35 rotates synchronously, thereby driving the threaded rod 33 to rotate. Since the sliding rod 31 is threadedly connected to the threaded rod 33 and slides on the inner wall of the fixing post 32, the sliding rod 31 slides along the axial direction of the fixing post 32. When the length is adapted to the wall, release the handle 38, the telescopic spring 39 returns to its original position, and push the handle 38 into the corresponding circular groove 311. At this time, the turntable 37 is locked, the telescopic component 3 is fixed in length, and the device clamps the wall with the frame 1 through the support rod 2, completing the installation and fixing.

[0037] When workers are installing the guardrail, they first adjust the height of the guardrail 5 according to the height of the workers. During adjustment, the pull rod 41 is pulled upward, the movable block 43 compresses the compression spring 42 and moves upward, disengaging from the slot 44 to release the limit. Then, the rotating shaft 45 is rotated to drive the connecting plate 47 and the buckle plate 49 to rotate. When the buckle plate 49 and the frame 1 are misaligned, moving the guardrail 5 to the right can disengage the rotating shaft 45 and the fixing slot 48 to release the limit. Then, the rotating shaft 45 is inserted into the fixing slot 48 of the corresponding height. Then, the limit on the rotating shaft 45 is released in the same way, and the slide 46 is rotated to make the buckle plate 49 lock the frame 1. Then, the pull rod 41 is released, and the compression spring 42 will push the movable block 43 and the slot 44 to insert and limit the rotating shaft 45, ensuring the stability of the guardrail 5, so as to protect workers of different heights.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
