Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a safety protection device for openings. Background Technology

[0002] During construction, numerous openings are often left in floor slabs for the installation of equipment such as water pipes and ventilation ducts. However, at different construction stages, these openings frequently become pathways for construction debris to fall, potentially creating safety hazards in the areas below. To prevent falls, guardrails or wooden planks are typically used for protection. However, guardrails can obstruct passageway and hinder the flow of people and materials during construction; while wooden planks, lacking effective securing measures, are prone to displacement or loss, making it difficult to provide consistently reliable protection. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safety protection device for openings, so as to solve the problems that in the existing technology, in order to prevent the occurrence of falling accidents from openings, the use of guardrails will occupy the passage space during actual construction, affecting the flow of personnel and materials, while the wooden board covering method lacks effective fixing measures, which is prone to displacement or loss, and it is difficult to provide a reliable protective effect continuously.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A safety protection device for openings, comprising:

[0006] At least two support rods are arranged opposite each other, each support rod is provided with a mounting rod, and each mounting rod is provided with a plurality of locking grooves arranged in an array along the vertical direction;

When disassembly is required, remove the baffle through the snap fastener, and use the telescopic rod to separate the support rod from the opening for future use.

[0011] 2. The telescopic rod can be adjusted according to the size of the opening, making it suitable for openings of different sizes and improving the versatility of the device. With the cooperation of the snap-fit ​​parts and locking groove, the baffle is firmly fixed, avoiding the defects of easy displacement or loss in the wooden board covering method. Compared with guardrails, the baffle design does not occupy additional passage space, ensuring the smooth flow of personnel and materials.

[0012] Furthermore, the snap-fit ​​component includes two snap-fit ​​blocks slidably disposed on the baffle and corresponding to the two mounting rods respectively, and an elastic part. A connecting rod passes through the baffle, and the two ends of the connecting rod are respectively connected to the opposite sides of the two snap-fit ​​blocks. The elastic part is used to snap the two snap-fit ​​blocks into the corresponding locking grooves respectively.

[0013] Furthermore, the elastic part includes a pull plate and a spring. The baffle has a groove, and the pull plate is disposed in the groove. The pull plate is fixedly connected to the connecting rod.

[0029] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0030] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance.

[0031] like Figure 1-3As shown in the figure, this utility model embodiment proposes a safety protection device for openings, comprising: at least two support rods 10, arranged opposite each other, each support rod 10 having a mounting rod 20, and each mounting rod 20 having a plurality of locking grooves 21 arranged in an array along the vertical direction; a telescopic rod 30, with its opposite ends respectively connected to the opposite sides of the two support rods 10, for placing the two support rods 10 on the inner wall of the opening; and a baffle 40, slidably sleeved between the two mounting rods 20, and having a snap-fit ​​member 50 slidably provided inside the baffle 40. When the snap-fit ​​member 50 slides and snaps into one of the locking grooves 21, the baffle 40 covers the opening. In this embodiment, the opening is rectangular and the baffle 40 is also rectangular. Of course, in other embodiments, if the opening is circular, the baffle 40 can also be circular. The baffle 40 covers the opening and its edges protrude outside the opening. On the one hand, it can prevent the baffle 40 from falling and seal the opening. On the other hand, it can replace the traditional guardrail and facilitate passage.

[0032] In this embodiment of the invention, during installation, the length of the telescopic rod 30 is first adjusted according to the size of the opening to securely place the two support rods 10 on the inner wall of the opening. Then, a suitable baffle 40 is selected based on the opening size, and the baffle 40 is slidably fitted between the two mounting rods 20. The baffle 40 is then slid into the corresponding locking groove 21 via the snap-fit ​​50, allowing it to cover the opening and achieve a secure fixation, forming a protective barrier. When disassembly is required, the baffle 40 is removed via the snap-fit ​​50, and the telescopic rod 30 separates the support rods 10 from the opening for future use.

[0033] Specifically, such as Figure 1-3 As shown in this embodiment of the present invention, the snap-fit ​​member 50 includes two snap-fit ​​blocks 51 slidably disposed on the baffle 40 and corresponding to the two mounting rods 20 respectively, and an elastic part 60. A connecting rod 52 is inserted through the baffle 40, and the opposite ends of the connecting rod 52 are respectively connected to the opposite sides of the two snap-fit ​​blocks 51. The elastic part 60 is used to snap the two snap-fit ​​blocks 51 into the corresponding locking grooves 21 respectively.

[0034] By attaching the pressure plate to the mounting rod 20 and causing the baffle 40 to slide downwards under external force, the two locking blocks 51 also slide synchronously along the outer side of the mounting rod 20 until the locking blocks 51 align with the locking grooves 21. Under the action of the elastic part 60, the two locking blocks 51 are embedded into the corresponding locking grooves 21, completing the locking. Furthermore, the locking blocks 51 are wedge-shaped, making it easier for them to slide into the locking grooves 21 during installation. The locking blocks 51 and the locking grooves 21 fit tightly, firmly fixing the baffle 40 in the designated position and effectively preventing displacement or loosening.

[0035] Specifically, such as Figure 3As shown in the embodiment of this utility model, the elastic part 60 includes a pull plate 61 and a spring 62. The baffle 40 has a groove 41, and the pull plate 61 is provided in the groove 41. The pull plate 61 is fixedly connected to the connecting rod 52. The spring 62 is provided in the groove 41, and the two ends of the spring 62 abut against the inner side of the groove 41 and the pull plate 61 respectively.

[0036] During installation, when the baffle 40 slides along the two mounting rods 20 to the appropriate position, the two locking blocks 51 slide on the outer surface of the mounting rods 20. At this time, the spring 62 is temporarily in a contracted state. Until the locking blocks 51 slide to align with the locking groove 21, under the elastic force of the spring 62, the two locking blocks 51 can automatically spring into the corresponding locking groove 21 after sliding into place, thereby realizing the automatic locking of the baffle 40 and tightly covering the opening. When disassembly is required, the connecting rod 52 is pushed by the pull plate 61, thereby disengaging the two locking blocks 51 from the locking groove 21. At this time, the baffle 40 can be removed for the next use.

[0037] Specifically, such as Figure 1-3 As shown in the embodiment of this utility model, the telescopic rod 30 includes a fixed part 31 and a telescopic part 32 connected by threads. The fixed part 31 is fixed to one of the support rods 10, and the telescopic part 32 is rotatably disposed on another support rod 10. In this way, by rotating the telescopic part 32 in both directions, the overall length of the telescopic rod 30 can be changed, thereby pushing the two support rods 10 to press against the inner wall of the opening to form a stable support. It can also adapt to different openings and improve versatility.

[0038] Based on the above solutions, such as Figure 1-3 As shown in this embodiment of the invention, the support rod 10 is vertically arranged, and its end facing the bottom of the opening has a positioning rod 11 extending horizontally to form an L-shaped structure for locking onto the opening on the floor, thus creating a larger contact area. Compared to a structure with only vertical support, the force is more evenly distributed, the anti-overturning ability is stronger, and the overall stability of the device is greatly improved. Furthermore, the surface of the support rod 10 that contacts the inner wall of the opening is provided with a friction layer (not shown in the figure). The friction layer can significantly increase the coefficient of friction, effectively preventing the support rod 10 from sliding or displacing under force or vibration, thereby maintaining the stability of the protective device. The friction layer can be made of materials such as rubber, silicone, or anti-slip coating, making it adaptable to concrete or other smooth surfaces, ensuring good adhesion to the inner walls of openings made of different materials.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
