Description

Technical Field

[0001] This utility model belongs to the field of construction safety technology, specifically, it relates to a movable opening protection device. Background Technology

[0002] Opening protection is an essential aspect of the safety of building construction. During construction, safety protection facilities are required to protect openings. In existing technologies, baffles are usually used to protect openings and are fixed with expansion bolts. The size of the baffles is significantly larger than the size of the opening. While fixed baffles ensure the stability of opening protection, when it is necessary to work around the opening, the fixing of the protective device and the obstruction of the baffles often cannot meet the construction requirements, thus hindering the construction progress.

[0003] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] Example 1

[0023] Please see Figures 1-4 The movable opening protection device shown in the figure includes a baffle 101 and a fixed plate 102. A first handle 103 is fixedly connected to the side of the baffle 101 away from the fixed plate 102. It also includes a mounting hole on one side of the baffle 101, a sliding plate 2 is slidably connected to the mounting hole, a pull plate 3 is fixedly connected to the side of the sliding plate 2 away from the baffle 101, a second handle 4 is fixedly connected to the side of the pull plate 3 away from the fixed plate 102, a bolt 5 is threadedly connected to the side wall of the baffle 101, one end of the bolt 5 is abutted against the side wall of the sliding plate 2, and the fixed plate 102 is provided with an adjustment component for rotating and adjusting the baffle 101 and a fixing component for fixing it to the opening.

[0024] The adjustment assembly includes an adjustment hole 601 on the side of the fixed plate 102 near the baffle 101, a tapered hole 602 on the side of the adjustment hole 601 away from the baffle 101, an adjustment plate 603 slidably connected to the adjustment hole 601, a tapered block 604 fixedly connected to the side of the adjustment plate 603 away from the baffle 101, the tapered block 604 matching the tapered hole 602, an adjustment rod 605 fixedly connected to the side of the adjustment plate 603 away from the tapered block 604, one end of the adjustment rod 605 connected to the baffle 101, and a pressing assembly for pressing the adjustment plate 603 in the adjustment hole 601.

[0025] It should be noted that by setting up the fixing components, while achieving the shielding and protection of the hole and ensuring the stability of the baffle 101 in the hole protection, the adjusting components can be used to continuously rotate the baffle 101 to facilitate the sequential exposure of the shielded parts around the hole, thereby facilitating construction work around the hole, meeting actual construction needs, and improving construction progress.

[0026] Please see Figure 3 The compression component shown in the figure is a compression spring 7. The compression spring 7 is sleeved on the adjusting rod 605 at the inner side wall of the adjusting hole 601. The two ends of the compression spring 7 are connected to the inner wall of the adjusting hole 601 and the adjusting plate 603, respectively.

[0027] It should be noted here that the setting of the compression component makes it easy to use the elastic force of the compression spring 7 after the baffle 101 is pulled, so that the conical block 604 and the conical hole 602 abut against each other again, thereby realizing the connection and fixation between the baffle 101 and the fixed plate 102.

[0028] Working principle: When shielding and protecting building openings, the fixing plate 102 is first inserted into the opening, and under the action of the fixing components, the fixing plate 102 is connected to the inner wall of the opening, thereby fixing the baffle 101. This ensures the stability of the baffle 101 in shielding and protecting the opening.

[0029] When construction work is required around the hole, the sliding plate 2 can be retracted into the mounting hole by pulling the second handle 4. When the pull plate 3 on one side of the sliding plate 2 is aligned with or slightly smaller than the edge of the hole, the sliding plate 2 can be fixed by the bolt 5. At this time, construction work can be carried out on the uncovered part around the hole. After the construction work is completed, the first handle 103 can be pulled to move the adjusting plate 603 at one end of the adjusting rod 605 away from the fixed plate 102, thereby separating the conical block 604 from the conical hole 602. At this time, the baffle 101 can be rotated, which makes it easier to expose the covered part around the hole, thus facilitating construction work. Therefore, by continuously rotating the baffle 101, the covered part around the hole can be exposed in sequence, which facilitates construction work around the hole, meets the actual construction needs, and improves the construction progress.

[0030] Example 2

[0031] Please see Figure 2 and Figure 4This embodiment further illustrates Example 1. The fixing component shown in the figure includes a fixing cavity 801 opened in the fixing plate 102. Two through holes 802 are opened on the two inner walls opposite to each other in the fixing cavity 801. T-shaped rods 803 are slidably connected to the two through holes 802. The two inner walls of the fixing cavity 801 near the through holes 802 are fixedly connected to the U-shaped plate 804. The two T-shaped rods 803 are slidably connected to the U-shaped plate 804. The fixing cavity 801 is provided with a driving component for driving the two T-shaped rods 803. The side walls of the two T-shaped rods 803 are fitted with return springs 805. The two ends of the two return springs 805 are respectively connected to the side walls of the T-shaped rods 803 and the inner wall of the U-shaped plate 804.

[0032] It should be noted that: by setting the fixing component, under the cooperation of the driving component and the rotating component, the two T-shaped rods 803 are pushed away from each other. As the two T-shaped rods 803 are continuously squeezed and pushed, when the ends of the two T-shaped rods 803 that are away from each other abut against the inner wall of the hole, the movement of the two T-shaped rods 803 stops. Then, under the pressing action of the two T-shaped rods 803, the connection and fixation between the fixing plate 102 and the hole is realized.

[0033] Please see Figure 2 and Figure 4 The driving assembly shown in the figure includes a threaded rod 901 rotatably connected between two opposing inner walls of the fixed cavity 801. A driving plate 902 is threadedly connected to the side wall of the threaded rod 901. The two opposing sides of the driving plate 902 abut against the inner wall of the fixed cavity 801. Inclined plates 903 are fixedly connected to the two sides of the driving plate 902 near the two T-shaped rods 803. The fixed plate 102 is provided with a rotating assembly for rotating the threaded rod 901.

[0034] It should be noted that, through the configuration of the drive assembly, during the rotation of the threaded rod 901 by the action of the rotating assembly, the threaded meshing transmission between the threaded rod 901 and the drive plate 902, as well as the guiding action of the fixed cavity 801, will drive the inclined plates 903 on both sides of the drive plate 902 to move. During the movement of the two inclined plates 903, under the interaction force between the inclined plates 903 and the T-shaped rod 803 and the guiding action of the through hole 802, the two T-shaped rods 803 will be pushed away from each other.

[0035] Please see Figure 2 and Figure 4 The rotating assembly shown in the figure includes a rotating rod 1001 rotatably connected to the side of the fixed plate 102 near the baffle 101. The rotating rod 1001 is provided with transmission wheels 1002 on both the inner side wall of the fixed cavity 801 and the side wall of the threaded rod 901. The two transmission wheels 1002 are connected by a transmission belt 1003. A regular hexagonal rotating hole is opened at the end of the rotating rod 1001 near the baffle 101.

[0036] It should be noted that, due to the configuration of the rotating assembly, when the rotating rod 1001 is rotated using an Allen wrench, the threaded rod 901 will be driven to rotate under the transmission action of the transmission wheel 1002 and the transmission belt 1003.

[0037] Example 3

[0038] Please see Figure 1 This embodiment is a further explanation of other embodiments. In the figure, the baffle 101 and the sliding plate 2 are provided with clearance holes 11.

[0039] It should be noted that by opening clearance holes 11 on the surfaces of the baffle 101 and the sliding plate 2, the internal hex wrench can pass through the clearance holes 11 and be inserted into the rotation hole at one end of the rotating rod 1001, thereby enabling the rotation of the rotating rod 1001.
