[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] This application provides a technical solution, such as Figure 1-Figure 3 As shown; a temporary blocking device for a reserved hole in a construction project, comprising: a blocking baffle 1, which is arranged on the outside of the reserved hole and covers the reserved hole, an annular sealing gasket 11 is installed on its inner surface, the annular sealing gasket 11 is in contact with the wall, and an adjustment rope hole 12 is opened on its side surface.

[0030] In the embodiment of the present invention, the blocking baffle 1 is provided to block one end of the reserved hole, and the blocking claw mechanism 5 is supported to tightly block the reserved hole, thereby facilitating installation by the staff.

[0031] The annular baffle 2 is arranged at the center of one side of the blocking baffle 1, and an adjustment rope 21 is installed on the upper and lower sides of one side surface. The adjustment rope 21 moves through the adjustment rope hole 12, and a pulling ear 22 is installed on the upper and lower sides of the other side surface.

[0032] In the embodiment of the present invention, through the setting of the annular baffle 2, the adjusting rope 21 can be pulled to enable the adjusting rope 21 to drag the sliding ring 53 to move, thereby controlling the extension length of the telescopic pin 513, so that the telescopic pin 513 can be retracted into the cross-type claw seat 51, so as to facilitate the disassembly of the device, making its disassembly simpler, faster and more efficient.

[0033] The adjusting screw 3 is movably mounted at the center of the blocking baffle 1 , with two limit baffles 31 mounted on one end thereof. The two limit baffles 31 are respectively located on both sides of the blocking baffle 1 , and an inner hexagonal groove 32 is opened at one end thereof.

[0034] In the embodiment of the present utility model, by utilizing the setting of the adjusting screw 3 and the limiting of the two limiting baffles 31, the connection between the adjusting screw 3 and the blocking baffle 1 can be stably maintained and can keep rotating. At the same time, the threaded connection between the adjusting screw 3 and the internal threaded sleeve 52 can be utilized to clamp the blocking baffle 1 and the cross-type claw seat 51 on both sides of the reserved hole, thereby ensuring the firmness of the reserved hole blocking.

[0035] In the embodiment of the present invention, the provision of the inner hexagonal groove 32 enables a worker to quickly rotate the adjusting screw 3 using an inner hexagonal wrench, so that the device can be quickly installed or disassembled in the reserved hole.

[0036] The limiting slide bar 4 is installed on the other side of the blocking baffle 1 and is located on both sides of the adjusting screw 3 , and is evenly distributed on the outside of the adjusting screw 3 with the adjusting rope 21 .

[0037] In the embodiment of the present invention, the limiting slide rod 4 is set so that it can be slidably inserted into the outer baffle 521 on the internal threaded sleeve 52, thereby positioning the internal threaded sleeve 52 to prevent it from rotating, ensuring that the device can smoothly seal the reserved hole.

[0038] The blocking claw mechanism 5 is arranged on the other side of the blocking baffle 1, and includes: a cross-type claw seat 51, which is located on the other side of the blocking baffle 1, and each support rod has an adjustment groove 511 at one end, and a pin groove 512 on the side surface, the pin groove 512 is connected to the adjustment groove 511, and a telescopic pin 513 is slidably installed in the adjustment groove 511, and a pin rod 514 is installed on the telescopic pin 513, and the pin rod 514 is slidably set in the pin groove 512; an internal threaded sleeve 52 is installed at the center of the cross-type claw seat 51 and is connected to the adjustment groove 511. The screw rod 3 is threadedly connected, and an outer baffle plate 521 is installed at one end of its outer surface. The outer baffle plate 521 has the same adjustment rope holes 12 on the upper and lower sides, and slide rod holes on the left and right sides of the outer baffle plate 521. The limit slide rod 4 is slidably inserted into the slide rod holes; the sliding ring 53 is slidably mounted on the internal threaded sleeve 52 and is connected to the adjustment rope 21. A compression spring 531 is arranged between it and the outer baffle plate 521. The compression spring 531 is mounted on the internal threaded sleeve 52, and it is movably hinged to the pin rod 514 through a connecting strut 532.

[0039] In the embodiment of the present invention, by setting up the cross-type claw seat 51, its weight can be reduced and the stability of fixation can be ensured. At the same time, by utilizing the telescopic adjustment of the telescopic pin 513 in the adjustment groove 511, the device can meet the requirements of sealing reserved holes within a certain size range, thereby improving its scope of use.

[0040] In the embodiment of the present invention, the setting of the internal threaded sleeve 52 can be used to connect it with the adjusting screw 3 through a thread, thereby quickly adjusting the distance between the blocking baffle 1 and the cross-type claw seat 51, so that it can be clamped on both sides of the reserved hole, thereby quickly blocking the reserved hole and ensuring the firmness of the blockage.

[0041] In the embodiment of the present invention, the elasticity of the compression spring 531 is utilized to push the sliding ring 53 to move, and then the support of the connecting support rod 532 is utilized to push the telescopic pin 513 to always be outside, thereby facilitating the installation of the device.

[0042] In the embodiment of the utility model, when installing and disassembling the device, the dragging ear 22 can be manually pulled and the adjustment rope 21 can be used to pull the telescopic pin 513 to retract, and the cross-type claw seat 51 can be smoothly inserted into the reserved hole, thereby facilitating the installation and disassembly of the device.

[0043] In the present invention, the compression spring 531 is always in a compressed state; the compression spring 531 uses elastic force to enable the sliding ring 53 to use the support of the connecting support rod 532 to push the telescopic pin 513 out of the adjustment slot 511; ensuring that the compression spring 531 can always maintain elasticity, thereby enabling the telescopic pin 513 to automatically and quickly extend.

[0044] In the present invention, the size of the cross-type claw seat 51 is smaller than the inner diameter of the reserved hole, ensuring that it can quickly pass through the reserved hole.

[0045] In the present invention, after the telescopic pin 513 in the cross-type clamping claw seat 51 is extended, its size is larger than the inner diameter of the reserved hole, ensuring that after the cross-type clamping claw seat 51 passes through the reserved hole, the telescopic pin 513 can be clamped outside the reserved hole.

[0046] When using the present invention, the staff takes out the device and manually pulls the dragging ear 22 to move the annular baffle 2. Then, the adjusting rope 21 is dragged to move the sliding ring 53, compressing the compression spring 531 and simultaneously driving the connecting strut 532 to contract, causing it to drag the pin 514 downward and retract the telescopic pin 513 into the cross-type claw seat 51.

[0047] Then, the cross-shaped claw seat 51 is passed through the reserved hole, and the blocking baffle 1 is attached to the reserved hole. Then, the pulling ear 22 is released. At this time, the elasticity of the compression spring 531 is used to move the sliding ring 53, and the connecting support rod 532 is used to push the telescopic pin 513 to extend and make its size larger than the size of the reserved hole.

[0048] Finally, the staff can insert the hexagonal wrench into the inner hexagonal groove 32 and rotate it, so that the adjusting screw 3 starts to rotate, and then use the threaded connection between the adjusting screw 3 and the internal threaded sleeve 52 to gradually move the cross-type claw seat 51 toward the end of the reserved hole, and clamp the telescopic pin 513 at the end of the reserved hole, and use the telescopic pin 513 and the blocking baffle 1 to clamp the reserved hole, so as to block the reserved hole.

[0049] When disassembly is required, the staff inserts the hexagonal wrench into the inner hexagonal groove 32 and rotates it, and uses the threaded connection between the adjusting screw 3 and the internal threaded sleeve 52 to gradually move the cross-type claw seat 51 away from the reserved hole, thereby loosening the device on the reserved hole. The staff then pulls the dragging ear 22 to drive the sliding ring 53 to move, and then retracts the telescopic pin 513 into the cross-type claw seat 51, and then the device can be pulled out from the reserved hole.

[0050] When this device is implemented, the staff can classify it by size based on the common reserved hole sizes, and thus divide the devices into large, medium, small and other types according to the diameter of the reserved holes, so that the staff can choose devices of different sizes for use according to actual conditions.
