Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology, specifically relating to a high-altitude construction guardrail. Background Technology

[0002] In modern construction, especially during high-altitude operations, safety is paramount. Traditional high-altitude construction guardrails, typically made of metal or rigid plastic, are designed to be sturdy and heavy. However, transporting them in confined spaces like stairwells often requires multiple people and is difficult due to space constraints, potentially damaging the guardrails or stairwell facilities. Moving these traditional guardrails not only consumes significant physical effort but can also impact work efficiency and construction progress. Furthermore, their large size occupies considerable storage space, further increasing storage difficulty and costs. Utility Model Content

[0003] The purpose of this utility model is to provide a high-altitude construction guardrail to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-altitude construction guardrail includes a base, the base being U-shaped in general, and a folding mechanism installed on the upper side of the base;

[0006] The folding mechanism includes two auxiliary rods distributed on the left and right. A pivot is installed on the inner side of the bottom of each auxiliary rod. The auxiliary rod is hinged to the base on the left and right sides through the pivot. The auxiliary rod can only rotate inward in one direction. The horizontal height of the axis of the pivot located on the upper right side is higher than the horizontal height of the axis of the pivot located on the upper left side. The inner side of the auxiliary rod and the inner side of the base are provided with a connecting groove. Multiple sliders are slidably installed on the inner side of the groove. A crossbar is fixedly connected between the corresponding left and right sliders. A flexible belt is installed on the upper side of the base, which is evenly distributed on the left and right sides. Multiple crossbars are evenly spaced and fixedly connected to the flexible belt. A fixing component is installed on the inner side of the uppermost crossbar.

[0007] The fixing assembly includes a cavity through which the uppermost crossbar and the sliders on its left and right sides are passed. Slide rods symmetrically distributed and slidably connected to the cavity are installed inside the cavity. A tension spring is installed between the two slide rods. A locking tongue with an upwardly inclined surface is fixed to the outside of each slide rod. Locking grooves matching the locking tongues are opened on the sides of both the left and right auxiliary rods. A straight groove penetrating the crossbar and facing left and right is opened in the middle of the crossbar. Two pull bolts distributed left and right are slidably installed inside the straight groove, and both pull bolts are fixedly connected to the corresponding slide rods on the left and right.

[0008] Both of the left and right slides have baffles fixedly connected to their tops.

[0009] The number of the base and the folding mechanism are both two sets, symmetrically distributed vertically, and the two bases are fixedly connected to form an H shape.

[0010] A rubber strap is fixedly connected to the side of the auxiliary rod located on the upper right side. Multiple buckles are evenly distributed on the upper side of the rubber strap. A locking pin that matches the buckle is fixed to the front side of the auxiliary rod located on the upper right side.

[0011] Each of the four auxiliary rods is fixedly fitted with a fixing lug, and the fixing lugs on the left and right sides are symmetrically distributed. The fixing lug on the right side is located on the front side of the auxiliary rod, and the fixing lug on the left side is located on the rear side of the auxiliary rod.

[0012] The folding mechanism allows the guardrail to be folded up when not in use, significantly reducing its space occupation and making it easier for users to move and carry during operations. This effectively reduces the labor intensity of workers during installation and use, and makes it easier to carry and store. The unidirectional rotating auxiliary rod and the multiple sliders installed on the inner side of the sliding groove work together to form lateral support for the guardrail by connecting the crossbar, enhancing the structural strength of the guardrail and enabling it to withstand certain impact forces, providing effective protection for workers working at heights. At the same time, the design of each component of the guardrail is simple and clear, easy to inspect and maintain, reducing operating costs. The design of the tension spring, the upward-sloping locking tongue, and the locking groove allows the locking tongue to slide into the locking groove when the uppermost crossbar is pulled to the designated position, thus achieving automatic locking. The bolt design makes the unlocking process equally convenient; users only need to... Pulling the bolt inward releases the lock, making the unfolding and locking process of the guardrail simple and quick, improving the overall ease of use. The baffle at the top of the slide rail prevents the slider from slipping out of the slide rail, thereby improving the reliability of the guardrail. The design of two sets of bases and folding mechanisms, symmetrically distributed vertically, increases the overall height of the guardrail within a unit width, thereby improving the overall flexibility and protective effect of the guardrail. When the folding mechanism is folded up, the locking pins are inserted into the inside of the lock to wrap and fix the entire sub-bar, preventing accidental unfolding during storage and improving safety. The fixing ears can be used to fix the guardrail to the construction platform or other structures, improving the flexibility of the guardrail. At the same time, the staggered design of the fixing ears on the left and right sides facilitates the connection and fixation of the guardrail while ensuring the normal folding of the sub-bar, avoiding interference with the sub-bar and improving the reliability of the guardrail.

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-7 As shown, a high-altitude construction guardrail includes a base 1, which is U-shaped in general, and a folding mechanism is installed on the upper side of the base 1.

[0024] The folding mechanism includes two auxiliary rods 2 distributed on the left and right. A pivot 3 is installed on the inner side of the bottom of the auxiliary rod 2. The auxiliary rod 2 is hinged to the base 1 on the left and right through the pivot 3. The auxiliary rod 2 can only rotate inward in one direction. The horizontal height of the axis of the pivot 3 located on the upper right side is higher than the horizontal height of the axis of the pivot 3 located on the upper left side. The inner side of the auxiliary rod 2 and the inner side of the base 1 are provided with a connecting groove 4. Multiple sliders 5 are slidably installed on the inner side of the groove 4. A crossbar 6 is fixedly connected between the corresponding left and right sliders 5. Flexible belts 7 are evenly distributed on the upper side of the base 1. Multiple crossbars 6 are evenly spaced and fixedly connected to the flexible belts 7. A fixing component is installed on the inner side of the uppermost crossbar 6.

[0025] In this utility model, the flexible belt 7 is bendable and has low overall elasticity. When the guardrail is not unfolded, the sliders 5 are all inside the grooves 4 inside the base 1, the auxiliary rods 2 are in a horizontal folded state, and the auxiliary rods 2 on the right side cover the auxiliary rods 2 on the left side.

[0026] When the guardrail needs to be unfolded and used, the guardrail is laid flat on the ground. Then, the two auxiliary bars 2 on the left and right are unfolded respectively, so that the inner groove 4 is aligned with the groove 4 of the base 1. Then, the outermost horizontal bar 6 is pulled outward and fixed to the top of the auxiliary bar 2 by the fixing component. At this time, the flexible belt 7 evenly arranges the middle horizontal bars 6.

[0027] The folding mechanism allows the guardrail to be folded up when not in use, greatly reducing its space occupation and making it easier for users to move and carry during operations. This effectively reduces the labor intensity of workers during installation and use, and makes it easier to carry and store. The unidirectional rotating auxiliary rod 2 and the sliding groove 4 have multiple sliders 5 installed on the inside, which work together to form the lateral support of the guardrail through the connecting crossbar 6, enhancing the structural strength of the guardrail and enabling it to withstand a certain impact force, providing effective protection for workers working at heights. At the same time, the design of each component of the guardrail is simple and clear, easy to inspect and maintain, and reduces the cost of use.

[0028] The fixing assembly includes a cavity 8, which passes through the uppermost crossbar 6 and the sliders 5 on its left and right sides. Inside the cavity 8, there are slide rods 9 that are symmetrically distributed and slidably connected to the cavity 8. A tension spring 10 is installed between the two slide rods 9. A locking tongue 11 with an upwardly inclined surface is fixed to the outside of the slide rod 9. The sides of the two auxiliary rods 2 are provided with locking grooves 12 that match the locking tongue 11. The middle of the crossbar 6 is provided with a straight groove 13 that runs through the front and back and faces left and right. Two pull bolts 14 that are distributed left and right are slidably installed inside the straight groove 13, and the two pull bolts 14 are fixedly connected to the corresponding slide rods 9 on the left and right.

[0029] The design of the tension spring 10, the upward-sloping locking tongue 11, and the locking groove 12 allows the locking tongue 11 to slide into the locking groove 12 when the uppermost horizontal bar 6 is pulled to the designated position, thus achieving automatic locking. The design of the bolt 14 makes the unlocking process equally convenient. Users only need to pull the bolt 14 inward to unlock, making the unfolding and locking process of the guardrail simple and quick, improving the overall ease of use of the guardrail.

[0030] Both left and right slides 4 have baffles 15 fixedly connected to their tops.

[0031] The baffle 15 at the top of the slide 4 is used to prevent the slider 5 from sliding out of the slide 4, thereby improving the reliability of the guardrail.

[0032] The number of base 1 and folding mechanism are two sets, which are symmetrically distributed vertically, and the two base 1 are fixedly connected to form an H shape.

[0033] The design of having two sets of base 1 and folding mechanism, symmetrically distributed vertically, increases the overall height of the guardrail within a unit width, thereby improving the overall flexibility and protective effect of the guardrail.

[0034] A rubber strap 16 is fixedly connected to the side of the auxiliary rod 2 located on the upper right side. Multiple buckles 17 are evenly distributed on the upper side of the rubber strap 16. A locking pin 18 matching the buckle 17 is fixed to the front side of the auxiliary rod 2 located on the upper right side.

[0035] The rubber strap 16 allows the locking pin 18 to be inserted into the inside of the buckle 17 to wrap and fix the entire auxiliary rod 2 when the folding mechanism is folded up, preventing accidental unfolding during storage and improving safety.

[0036] All four auxiliary rods 2 are fixedly installed with fixing ears 19 on their outer sides, and the fixing ears 19 on the left and right sides are symmetrically distributed. The fixing ear 19 on the right side is located on the front side of the auxiliary rod 2, and the fixing ear 19 on the left side is located on the rear side of the auxiliary rod 2.

[0037] The fixing lugs 19 can be used to fix the guardrail to the construction platform or other structures, improving the flexibility of the guardrail. At the same time, the staggered design of the fixing lugs 19 on the left and right sides facilitates the connection and fixation of the guardrail, while also ensuring that the sub-post 2 can be folded normally, avoiding interference with the sub-post 2 and improving the reliability of the guardrail.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
