[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 2As shown, this utility model provides a device for pre-reserving openings in building engineering, including a base laying plate 11 and a ground body 12. First, the base laying plate 11 is placed in direct contact with the ground body 12, providing bottom support for the entire device and ensuring stability during construction. A pre-reserved long plate 13 on the base laying plate 11 is prepared for pre-reserving openings. Multiple sets of speed-reducing slide rails 14 are installed on the pre-reserved long plate 13, while a descending plate 15 is smoothly installed on the speed-reducing slide rails 14. The speed-reducing slide rails 14 effectively control the descent speed of the descending plate 15 and ensure its smooth descent, while also ensuring safety during construction and avoiding potential accidents caused by rapid descent. A stop sleeve 16 fitted onto the pre-reserved long plate 13 is positioned and securely fixed through multiple sets of connecting fixing posts 17. This allows construction personnel to determine the depth of the pre-reserved opening according to specific construction requirements, meeting the needs of different projects. Multiple sets of supports 18 on the stop head 16 provide positions for the spring installation, and multiple sets of parallel slide rails 19 on the base laying plate 11 provide sliding tracks for the receiving column 21 and the slider 22. A rotating shaft 23 inside the receiving column 21 passes through the receiving column 21 and connects to the parallel slide rails 19. A remote lever 24 at one end of the rotating shaft 23 provides convenient control for the operator. By manipulating the remote lever 24, the rotating shaft 23 can drive the slider 22 to slide smoothly on the parallel slide rails 19, realizing the adjustment of the device. The rotating collection column 25 is sleeved on the rotating shaft 23, and the pull posts 26 on the multiple sets of sliders 22 are connected to the interception cloth 27 on the rotating collection column 25. The cross-section plate 28 on the pull post 26 further enhances the interception effect. This combination forms an effective protective barrier, preventing debris from falling into the reserved area during construction, ensuring the cleanliness of the construction site and the smooth progress of construction. First foam pads 29 and second foam pads 31 are respectively installed on the multiple sets of support columns 18 and the lowering plate 15. During the movement of the lowering plate 15, the foam pads act as a buffer, protect the components of the device, and extend its service life. Leak-proof plates 32 installed on the multiple sets of speed-reducing slide rails 14 prevent incorrect operation by construction personnel. Four sets of ground cone nails 33 on the leak-proof plate 32 pass sequentially through the multiple sets of speed-reducing slide rails 14, the reserved long plate 13, and the leak-proof plate 32, and are then fixed to the ground body 12. The other four sets pass through the base paving plate 11 and the reserved long plate 13 before being fixed to the ground body 12. This stable connection ensures the entire device is firmly integrated with the ground, greatly enhancing the stability and reliability of the device during construction, effectively resisting various external forces and vibrations during construction, and ensuring the quality of the pre-reserved holes. The fixing plate 34 on the base paving plate 11 provides installation space for the arched door frame 35. The door panel 36, which is rotatably connected to the arched door frame 35, can be easily opened and closed, facilitating operation and observation by construction personnel. The latch on the arched door frame 35 ensures that the door panel 36 is securely locked when closed, guaranteeing construction safety.One end of a spring fitted on each of the multiple sets of support pillars 18 is fixed to the support pillar 18, and the other end is elastically connected to the landing plate 15. During the movement of the landing plate 15, the spring provides elastic cushioning, making the descent process smoother. Limiting holes on the multiple sets of parallel slide rails 19 can limit the movement range of the slider 22, preventing excessive movement of the slider 22 that could lead to device malfunction or construction errors.

[0024] like Figures 2 to 4 As shown, when using the device, the user attaches the reserved long plate 13 to the base laying plate 11 and fixes it with four sets of ground cone nails 33. Multiple sets of deceleration slide rails 14 on the reserved long plate 13 cooperate with the descending plate 15 to control the descent speed and stability of the descending plate 15. If a person accidentally steps onto the descending plate 15, the deceleration slide rails 14 ensure a slow descent, reducing accidental injury. The stop sleeve 16 and multiple sets of connecting fixing posts 17 fitted on the reserved long plate 13 can adjust and fix the reserved hole depth according to specific construction requirements, meeting the needs of different projects. The multiple sets of support posts 18 and the first foam pad 29 and second foam pad 31 on the descending plate 15 act as a buffer when the descending plate 15 moves or is impacted. The foam pads can minimize the damage they suffer, protect device components, reduce wear, and reduce injury to construction personnel in case of accidental falls. The leak-proof plate 32 on the deceleration slide rail 14 prevents construction personnel from falling. Multiple sets of ground cone fixing nails 33 are installed on the leak-proof plate 32. Some of them pass through the speed-reducing slide rail 14, the reserved long plate 13 and the leak-proof plate 32 and are fixed to the ground body 12. Others pass through the base laying plate 11 and the reserved long plate 13 and are fixed to the ground body 12, so that it can withstand construction external forces and vibrations. Springs fitted on multiple sets of support columns 18 are fixed at one end to the support column 18 and elastically connected to the landing plate 15 at the other end, which further buffers the impact force when falling and enhances the stability and safety of the landing plate 15 movement.

[0025] The specific usage and function of this embodiment are as follows:

[0026] When using this device, the user first places it at the construction location, ensuring the base paving plate 11 is flush with the ground body 12 and secured with ground cone nails 33. Adjusting the position of the stop sleeve 16 on the reserved long plate 13 according to construction needs and securing it with connecting fixing posts 17 determines the reserved hole depth. The construction worker operates the joystick 24 to rotate the rotating shaft 23, causing the slider 22 to move on the parallel slide rail 19 and adjust the position of the intercepting cloth 27. If the construction worker inadvertently steps on the lowering plate 15, it will descend smoothly along the deceleration slide rail 14. During construction, the door panel 36 on the arched door frame 35 can be opened and closed as needed and secured with pins. This device contains multiple deceleration... The slide rail 14 and spring work together to smoothly control the descent speed of the lowering plate 15, thus buffering the injury to the construction worker when it falls in. The stop sleeve 16 and the connecting fixing column 17 control the reserved depth of the hole to meet different requirements and prevent the construction worker from falling in and falling out directly. The intercepting cloth 27 prevents and reminds the construction worker not to approach the reserved hole. The first foam pad 29 and the second foam pad 31 provide cushioning and protect the construction worker from injury. The arched door frame 35 and the door panel 36 facilitate operation and observation. The ground cone nail 33 makes the device firmly connected to the ground, enhances stability, and reduces the risk of displacement. The limiting hole on the parallel slide rail 19 limits the movement range of the slider 22 and determines the protection range.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
