All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0040] Example
[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This embodiment proposes a rigid isolation fence that is easy to open, close and disassemble, including several fence frames 1;
[0042] Each adjacent frame 1 is provided with a vertical post 2, and the end of the adjacent frame 1 closest to the vertical post 2 can be hinged to the vertical post 2 and swing.
[0043] In use, several frames 1 are placed around the exposed equipment, and uprights 2 are installed between adjacent frames 1. The adjacent frames 1 are respectively hinged to the uprights 2. In this way, the exposed equipment can be safely protected by the uprights 2 and several frames 1.
[0044] The rigid isolation fence disclosed in this embodiment is easy to open, close and disassemble. Because the fence frame 1 is set on both sides of the post 3, the fence frame 1 can surround the exposed equipment, which is convenient for the safety protection of the exposed equipment. Thus, the rigid isolation fence that is easy to open, close and disassemble has the beneficial effects of being able to stably and safely isolate dangerous sources, providing good safety protection for exposed equipment, being easy to disassemble, being easy to maintain equipment, being easy to prevent heavy objects and personnel from hitting the equipment, and being easy for personnel to enter and exit.
[0045] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The upright 2 has a post 3, which is parallel to the fence frame 1. When the post 3 and the fence frame 1 are parallel to each other, it is easy to connect the post 3 and the fence frame 1 by hinge, making the connection more convenient.
[0046] The column 3 is provided with a first connecting ear 4 and a second connecting ear 5 in the radial direction. The ends of the first connecting ear 4 and the second connecting ear 5 near the column 3 are fixedly connected to the outer wall of the column 3 in the radial direction. The first connecting ear 4 and the second connecting ear 5 are located on the same side of the column 3. The arrangement of the first connecting ear 4 and the second connecting ear 5 facilitates the hinged connection of the railing frame 1, so that the railing frame 1 can rotate along the axis of the first connecting ear 4 and the second connecting ear 5, thereby realizing opening and closing, and facilitating disassembly and assembly.
[0047] The first connecting lug 4 and the second connecting lug 5 are distributed at intervals along the axial direction of the column 3, so that the force at the hinge is even and the adjacent frame 1 is more firmly connected to the column 2.
[0048] The first connecting ear 4 and the second connecting ear 5 each have a first fixed end 6 and a first hinge end 7. The first fixed end 6 is fixedly connected to the outer wall of the column 3. The first hinge end 7 has a first through hole 8. The first through hole 8 passes through the first hinge end 7 along the axial direction of the column 3. The setting of the first fixed end 6 makes the railing 1 have a certain gap with the column 3 when it is connected to the upright 2, which facilitates the swing opening and closing of the railing 1. The first through hole 8 facilitates the insertion of the pin 20, thereby realizing the hinged connection between the railing 1 and the upright 2.
[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The column 3 is also provided with a first movable connecting ear 9 and a second movable connecting ear 10. The first movable connecting ear 9 and the second movable connecting ear 10 are rotatably connected to the column 3 at the end near the column 3. The first movable connecting ear 9 is located at the upper end of the first connecting ear 4, and the second movable connecting ear 10 is located at the upper end of the second connecting ear 5.
[0050] Both the first movable connecting ear 9 and the second movable connecting ear 10 have a second fixed end 11 and a second hinge end 12. The second fixed end 11 is rotatably sleeved on the column 3. The second hinge end 12 has a second through hole 13, which passes through the second hinge end 12 along the axial direction of the column 3. The arrangement of the first movable connecting ear 9 and the second movable connecting ear 10 allows the railing frame 1 to be adjusted at a larger angle on the column 2, with greater flexibility and more suitable angles. This makes it easier for staff to adjust the angle between the railing frame 1 and the column 2 according to the site conditions. The second fixed end 11 can enhance the structural strength of the first movable connecting ear 9 and the second movable connecting ear 10 and prevent wear. The second through hole 13 also facilitates the insertion of the pin 20, making it convenient for the railing frame 1 and the column 2 to be hinged.
[0051] The railing frame 1 has an outer frame 14, and the two ends of the outer frame 14 are respectively provided with a first hinge seat 15, a second hinge seat 16, a third hinge seat 17 and a fourth hinge seat 18. The first hinge seat 15 and the second hinge seat 16 are symmetrically distributed with the third hinge seat 17 and the fourth hinge seat 18. The railing frame 1 and the upright 2 are hinged together through the first hinge seat 15, the second hinge seat 16, the third hinge seat 17 and the fourth hinge seat 18, which facilitates the opening and closing of the railing frame 1 on the upright 2 and makes it convenient for maintenance of the equipment.
[0052] The outer frame 14 is provided with several support rods 19 inside. The support rods 19 are fixedly connected to the inner side of the outer frame 14 at intervals and evenly. The support rods 19 enhance the structural strength of the outer frame 14. At the same time, they prevent personnel from entering the enclosure through the outer frame 14 and prevent the equipment from being accidentally bumped by vehicles, other objects or personnel, which could cause abnormal equipment operation.
[0053] Both the first through hole 8 and the second through hole 13 are equipped with pins 20. The pins 20 serve to connect the railing frame 1 and the upright 2, making it easy for the railing frame 1 and the upright 2 to be disassembled and assembled, while not affecting the rotation of the railing frame 1.
[0054] The pin 20 has a rod 21, and one end of the rod 21 has a cap 22. The diameter of the cap 22 is larger than the diameter of the rod 21. The cap 22 and the rod 21 are integrally formed. When the operator inserts or removes the pin 20, the cap 22 is easy for the operator to grasp. At the same time, the cap 22 effectively limits the insertion depth of the rod 21, preventing the pin 20 from falling out of the first through hole 8 and the second through hole 13.
[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the upright 2, the frame 1, and the pin 20 are all made of stainless steel. Carbon powder is applied between the surface of the pin 20 and the mating surface for lubrication when they are mated together.
[0056] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the upright 2, the main load-bearing component of the isolation fence, is inserted into a cavity in concrete or ground of sufficient strength; the fence frame 1, the main isolation component of the isolation fence, works with the upright 2 to provide isolation; and the pin 20 is a connecting component that connects the upright 2 and the fence frame 1.
[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The specific operating principle of the rigid isolation fence in this embodiment, which is easy to open, close, and disassemble, is as follows:
[0058] During installation, first drill holes in concrete or sufficiently strong ground, with a depth of not less than 15cm, for installing the uprights 2. The size of the holes should match the diameter of the uprights 2 to prevent excessive wobbling. The uprights 2 and the fence frame 1 are connected by pins 20. When the equipment needs to be inspected, personnel can open and close the fence normally by inserting or removing one side of the pins 20. When the equipment needs to be repaired, to prevent the fence from obstructing repairs, the fence frame 1 can be quickly removed by pulling out the pins 20 and the uprights 2, leaving sufficient space for maintenance personnel to move around. This allows for effective protection of equipment installed in public areas, preventing heavy objects and personnel from affecting the normal operation of the equipment. The fence can also be quickly disassembled during equipment inspection and maintenance, leaving sufficient space for work.
[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
