Description

Technical Field

[0001] The utility model relates to the technical field of wall opening protection, and particularly relates to a retractable wall opening protection device. Background Technique

[0002] Wall reserved openings (also known as drilled openings) refer to the openings deliberately left during the construction of buildings or facilities for the convenience of installing equipment, wiring, or maintenance. However, these openings may become potential safety hazards if not properly protected. To ensure the safety of personnel and equipment and reduce the occurrence of accidents, the safety protection of wall reserved openings is of great importance.

[0003] When carrying out traditional protection for wall reserved openings, construction workers often only take a protection measure of a crossbar for the wall reserved openings. Not only is the safety level low, but there is also a risk of the crossbar falling off if the protection is improper. The length of the crossbar is usually fixed, so it will also cause waste of resources and materials and cannot meet the on-site safety protection requirements.

[0004] At present, retractable protection devices have emerged in the prior art, usually in the form of a protection grid. The inside of the protection grid is provided with protection rods. The directions of the protection rods are different, crisscrossing. Both the vertical ends and the horizontal ends of the protection rods can be retracted. The outermost ends of the protection rods are surrounded by a protection frame. Although the reserved opening protection device in the form of a protection grid in the prior art can improve the protection effect and can be reused multiple times, its structure is relatively complex, the installation and disassembly efficiency is low, which slows down the construction efficiency, increases the labor intensity, and is not convenient for handling. Content of the Utility Model

[0005] To solve the technical problems of low protection effect, complex structure, and low disassembly and assembly efficiency of the reserved opening protection device in the prior art, the utility model provides a retractable wall opening protection device.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A retractable wall opening protection device includes telescopic rods. The telescopic rods include vertical rods and horizontal rods. The vertical rods are arranged vertically, the horizontal rods are arranged horizontally, the vertical rods and the horizontal rods are perpendicularly and cross-connectedly connected, and the connection between the vertical rods and the horizontal rods is detachable. The two ends of the horizontal rods can abut against the side walls of the wall opening. The utility model protects the wall reserved openings through the retractable vertical rods and horizontal rods. The vertical rods and the horizontal rods are firmly connected as a whole, can stably and effectively protect wall reserved openings of different sizes, are quick to install, convenient to disassemble, easy to carry, can be reused, greatly save manpower and material resources, are applicable to various construction environments, and can improve the construction efficiency.

[0008] As a preferred implementation of a retractable wall opening protection device, the vertical rod and the horizontal rod are connected by a right-angle fastener. The right-angle fastener is a commonly used structural member in construction engineering, which can stably and reliably connect the vertical rod and the horizontal rod vertically and crosswise into one body, and is convenient for installation and disassembly.

[0009] As a preferred implementation of a retractable wall opening protection device, the vertical rod includes a vertical main rod. The vertical main rod is a tubular structure. The inner wall of the vertical main rod is provided with internal threads. The bottom of the vertical main rod is connected with a lead screw. The outer peripheral surface of the lead screw is provided with external threads. The bottom end of the lead screw is installed on the base. The top end of the lead screw is inserted into the interior of the vertical main rod, and the lead screw is threadedly connected with the vertical main rod. Setting the lead screw at the bottom of the vertical main rod and setting the base at the bottom of the lead screw are convenient for improving the stability of the overall structure. The vertical main rod is a seamless steel pipe with high structural strength and is not easily deformed.

[0010] As a preferred implementation of a retractable wall opening protection device, there is one vertical rod and two horizontal rods. The two horizontal rods are arranged in parallel. This further improves the stability of the protection.

[0011] As a preferred implementation of a retractable wall opening protection device, the horizontal rod includes a horizontal main rod. The horizontal main rod is a tubular structure. A horizontal auxiliary rod is sleeved inside the horizontal main rod. The horizontal auxiliary rod can be telescoped from one end of the horizontal main rod, and the horizontal auxiliary rod can slide and lock inside the horizontal main rod. This is convenient for adjusting the total length of the horizontal rod.

[0012] As a preferred implementation of a retractable wall opening protection device, a first jack is connected to one end of the horizontal main rod away from the horizontal auxiliary rod, and a second jack is connected to the end of the horizontal auxiliary rod extending out of the horizontal main rod. This is convenient for the two ends of the horizontal rod to stably abut against both sides of the wall reserved opening.

[0013] As a preferred implementation of a retractable wall opening protection device, locking holes are formed on the outer peripheral surface of the horizontal main rod. The locking holes penetrate through the tube wall of the horizontal main rod. The inner wall of the locking holes is provided with internal threads, and the locking holes are threadedly connected with locking screws. The locking screws can lock and release the horizontal auxiliary rod inside the horizontal main rod.

[0014] As a preferred implementation of a retractable wall opening protection device, a clamp is sleeved on the outer peripheral surface of the horizontal main rod. The clamp is provided with through holes corresponding to the locking holes. The inner wall of the through holes is provided with internal threads, and the locking screws are threadedly connected with the through holes. This can further improve the locking tightness of the horizontal auxiliary rod.

[0015] As a preferred implementation of a retractable wall opening protection device, the surface areas of the first support and the second support on the side away from the cross bar are larger than the cross-sectional area of the cross bar. Increasing the contact area between the two ends of the cross bar and the side walls of the reserved wall opening facilitates the stable abutment of the two ends of the cross bar against the two sides of the reserved wall opening.

[0016] As a preferred implementation of a retractable wall opening protection device, the first support and the second support are connected to an anti-slip pad on the side away from the cross bar. Increasing the friction between the two ends of the cross bar and the side walls of the reserved wall opening facilitates the stable abutment of the two ends of the cross bar against the two sides of the reserved wall opening.

[0017] The beneficial effects of the present utility model include:

[0018] The present utility model is quick to install, easy to disassemble, convenient to carry, can stably and effectively protect the reserved wall opening, and can be reused, adapting to reserved wall openings of different sizes, greatly saving manpower and material resources, being applicable to various construction environments, and capable of improving construction efficiency.

[0027] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0028] Refer to Figures 1-3 , in this embodiment, a retractable wall opening protection device is proposed, which includes a telescopic rod. The telescopic rod includes a vertical rod 1 and two horizontal rods 2. The vertical rod 1 is vertically arranged, the horizontal rods 2 are horizontally arranged, the two horizontal rods 2 are arranged in parallel, the vertical rod 1 and the horizontal rods 2 are perpendicularly and cross-connected, and the vertical rod 1 and the horizontal rods 2 are detachably connected through right-angle fasteners 3. The right-angle fasteners 3 are common structural members in construction projects.

[0029] The vertical rod 1 includes a vertical main rod 11. The horizontal rod 2 is connected to the vertical main rod 11 through a right-angle fastener 3. The vertical main rod 11 is a tubular structure, the inner wall of the vertical main rod 11 is provided with internal threads, the bottom of the vertical main rod 11 is connected with a lead screw 12, the outer peripheral surface of the lead screw 12 is provided with external threads, the bottom end of the lead screw 12 is installed on a base 13, the top end of the lead screw 12 is inserted into the interior of the vertical main rod 11, and the lead screw 12 is threadedly connected with the vertical main rod 11. By relatively rotating the vertical main rod 11 and the lead screw 12, the vertical main rod 11 and the lead screw 12 can be relatively telescoped, so as to adjust the total length of the vertical rod 1 to adapt to the height of the wall reserved opening.

[0030] Both ends of the transverse rod 2 can abut against the side walls of the wall opening. The transverse rod 2 includes a transverse main rod 21 which is of a tubular structure. A transverse auxiliary rod 22 is sleeved inside the transverse main rod 21. The transverse auxiliary rod 22 can telescopically extend from one end of the transverse main rod 21 and can slide and be locked inside the transverse main rod 21. Locking holes are formed on the outer peripheral surface of the transverse main rod 21, penetrating through the pipe wall of the transverse main rod 21. Internal threads are formed on the inner walls of the locking holes. A clamp 23 is sleeved on the outer peripheral surface of the transverse main rod 21. A through hole 24 is formed in the clamp 23, and internal threads are formed on the inner wall of the through hole 24. The through hole 24 is communicated with the locking hole. A locking screw 25 passes through the through hole 24 and the locking hole from the outside of the clamp 23, and the locking screw 25 is threadedly connected to the through hole 24 and the locking hole respectively. When the locking screw 25 is screwed into the through hole 24 and the locking hole, the end of the locking screw 25 entering the inside of the transverse main rod 21 can abut against the outer peripheral surface of the transverse auxiliary rod 22 inside the transverse main rod 21, thereby locking the transverse main rod 21 and the transverse auxiliary rod 22 so that the two cannot slide relative to each other; when the locking screw 25 is screwed out of the locking hole, the locking screw 25 is separated from the transverse auxiliary rod 22, and the transverse auxiliary rod 22 and the transverse main rod 21 can slide relative to each other to adjust the total length of the transverse rod 2. A first jack 4 is connected to one end of the transverse main rod 21 away from the transverse auxiliary rod 22, and a second jack 5 is connected to one end of the transverse auxiliary rod 22 extending out of the transverse main rod 21. The surface areas of the sides of the first jack 4 and the second jack 5 away from the transverse rod 2 are larger than the cross-sectional area of the transverse rod 2, and anti-slip pads are connected to the sides of the first jack 4 and the second jack 5 away from the transverse rod 2.

[0031] The working principle of this embodiment is as follows:

[0032] When it is necessary to protect the wall reserved opening, first use a right-angle fastener 3 to vertically and cross-fix the vertical rod 1 and the transverse rod 2 together. Then screw the lead screw 12 on the base 13 into the vertical main rod 11 from the bottom end of the vertical main rod 11, and then erect the vertical main rod 11 so that the base 13 is placed on the ground under the wall reserved opening, and make one end of the transverse main rod 21 away from the transverse auxiliary rod 22 abut against one side wall of the wall reserved opening. Loosen the locking screw 25 and adjust the length of the transverse auxiliary rod 22 extending out of the transverse main rod 21 so that the end of the transverse auxiliary rod 22 abuts against the other side wall of the wall reserved opening, so that both ends of the transverse rod 2 abut against the two side walls of the wall reserved opening. Then tighten the locking screw 25 to fix the relative positions of the transverse main rod 21 and the transverse auxiliary rod 22. Finally, rotate the lead screw 12 to adjust the total length of the vertical rod 1 to a suitable position to make it suitable for the current wall reserved opening.

[0033] This embodiment is quick to install, easy to disassemble, convenient to carry, can stably and effectively protect the wall reserved opening, and can be reused, adapting to wall reserved openings of different sizes, greatly saving manpower and material resources, being applicable to various construction environments, and being able to improve construction efficiency.
