Description

Technical Field

[0001] This utility model relates to the field of guardrail technology; more specifically, it relates to a guardrail that is easy to assemble and disassemble. Background Technology

[0002] Mesh fencing is a common security facility. Its robust structure and uniform mesh size combine isolation and warning functions, making it widely used for boundary protection in areas such as highways, railways, construction sites, and industrial parks. It effectively prevents people and animals from crossing freely, ensuring area safety and management order. The surface is typically galvanized or powder-coated, making it corrosion-resistant, anti-aging, and adaptable to harsh outdoor environments. It is easy to install and has low maintenance costs.

[0003] Currently, in the use of existing fencing technology, most equipment typically involves pre-installing embedded parts and then connecting the posts to the top of the embedded parts via threads. While this method is relatively simple, disassembly usually requires tools to separate the posts from the embedded parts, which is inconvenient, time-consuming, and labor-intensive, reducing the practicality of the equipment to some extent. Furthermore, existing equipment often has the mesh panels pre-welded into the equipment, and since the mesh panels are vulnerable parts, damage to the mesh panels may require disassembling the entire equipment, which is time-consuming, labor-intensive, and makes quick replacement of the mesh panels difficult, further reducing the practicality of the equipment. Therefore, there is an urgent need for a fencing system that is easy to assemble and disassemble to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fence that is easy to disassemble and assemble, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a fence that is easy to assemble and disassemble, comprising:

[0006] An embedded base is provided, with a quick-connect structure at its upper end and a vertical pole at its upper end. Connecting rings are fixedly connected to the outer surfaces of both the upper and lower ends of the vertical pole, and connecting pins are inserted into the connecting rings. One end of the connecting pin is provided with a replacement structure, which contains a mesh. The quick-connect structure includes a first connecting plate, a first rotating groove, a rotating positioning rod, a positioning sleeve, a movable sleeve, an insertion rod, a first spring, a positioning tooth groove, a second connecting plate, a second rotating groove, and a positioning groove. The replacement structure includes a grid frame, an installation groove, a movable groove, a locking plate, a second spring, and a limiting plate.

[0007] Preferably, the bottom of the first connecting plate is fixedly connected to the outer surface of the upper end of the pre-embedded base, and the inner surface of the outer surface at the four corners of the upper end of the first connecting plate is provided with a first rotating groove, and the inner surface of each of the four sets of first rotating grooves is hinged to a rotating positioning rod. The outer surface of the upper end of each of the four sets of rotating positioning rods is fitted with a positioning sleeve, and the outer surfaces on both sides of the positioning sleeve are fixedly connected with a movable sleeve, and an insertion rod is inserted into the inner surface of the movable sleeve. The outer surface of the insertion rod is fitted with a first spring, and the inner surface of the outer surfaces on both sides of the upper end of each of the four sets of rotating positioning rods is provided with a positioning tooth groove, and there are multiple sets of positioning tooth grooves. The outer surface of the upper end of the first connecting plate is attached to a second connecting plate, and the inner surface of the outer surface at the four corners of the second connecting plate is provided with a second rotating groove, and the inner surface of the upper inner wall of each of the four sets of second rotating grooves is provided with a positioning groove. The outer surface of the upper end of the second connecting plate is fixedly connected to a vertical rod. This design allows the insertion rod to move inside the movable sleeve.

[0008] Preferably, the external dimensions of one end of the rotating positioning rod are adapted to the internal dimensions of the first rotating groove and the second rotating groove. A limiting ring is fixedly connected to the outer surface of the upper end of the rotating positioning rod, and guide blocks are fixedly connected to the outer surfaces of both ends of the limiting ring. Guide grooves are opened inside the inner wall surfaces on both sides of the positioning sleeve, and the internal dimensions of the guide grooves are adapted to the external dimensions of the guide blocks. This design ensures that the rotating positioning rod is not blocked by the first rotating groove and the second rotating groove when it moves inside them.

[0009] Preferably, a limiting block is fixedly connected to the outer surface of the insertion rod, and the two ends of the first spring abut against the surface of one side of the limiting block and the inner wall surface of the movable sleeve, respectively. A positioning block is fixedly connected to the outer surface of one end of the insertion rod. The internal dimensions of the positioning groove and the external dimensions of the positioning block are adapted to each other, and the external dimensions of the positioning sleeve and the internal dimensions of the positioning groove are adapted to each other. This design allows the insertion rod to automatically reset after moving inside the movable sleeve.

[0010] Preferably, an installation groove is provided inside the outer surface of one side of the grid frame, and movable grooves are provided inside the inner wall surfaces on both sides of the upper end of the installation groove. A locking plate is engaged inside both sets of movable grooves, and a second spring is provided inside both sets of movable grooves. A limiting plate is fixedly connected to the inner wall surface at the lower end of the installation groove, and a mesh is inserted inside the installation groove. This design allows the locking plate to move inside the movable groove.

[0011] Preferably, the internal dimensions of the mounting groove are adapted to the external dimensions of the mesh, rectangular blocks are fixedly connected to the inner wall surfaces on both sides of the movable groove, rectangular grooves are opened on the inner surfaces of both sides of the locking plate, and the internal dimensions of the rectangular grooves are adapted to the external dimensions of the rectangular blocks. The two ends of the second spring abut against the inner wall surface of the movable groove and the outer surface of the upper end of the locking plate, respectively. The outer surface of the inner side of the limiting plate is inclined. This design makes the mesh more stable when installed inside the mounting groove.

[0012] The technical effects and advantages of this utility model are as follows: By pulling the insertion rod outward, the positioning block is disengaged from the inside of the positioning tooth groove. Then, the positioning sleeve can be moved upward, disengaging from the inside of the positioning groove. At this time, the rotating positioning rod can be hinged and rotated, disengaging from the inside of the second rotating groove. Thus, the first connecting plate and the second connecting plate can be disassembled without the aid of tools, which saves time and effort and improves the practicality of the equipment to a certain extent.

[0013] By moving the two sets of locking plates upwards, the lower ends of the two sets of locking plates are no longer attached to the outer surface of the mesh. At this point, the mesh can be pulled outwards. Then, the unused mesh can be inserted into the mounting slot and the limiting plate. Subsequently, the two sets of locking plates can be released, allowing the locking plates to automatically reset under the elasticity of the second spring, and the lower ends of the locking plates will then be attached to the outer surface of the mesh to complete the replacement of the mesh. This is quite convenient and does not require disassembling the entire device, which improves the practicality of the device to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The guardrail involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1, as Figures 1-4As shown, this embodiment proposes a fence that is easy to assemble and disassemble, including: a pre-embedded base 1, a quick-connecting structure 2 at the upper end of the pre-embedded base 1, and a vertical post 3 at the upper end of the quick-connecting structure 2. Connecting rings are fixedly connected to the outer surfaces of both the upper and lower ends of the vertical post 3, and connecting pins are inserted into the interior of the connecting rings. A replacement structure 4 is provided at one end of the connecting pin, and a mesh panel 5 is installed inside the replacement structure 4. The quick-connecting structure 2 includes a first connecting plate 21, a first rotating groove 22, a rotating positioning rod 23, a positioning sleeve 24, a moving sleeve 25, an insertion rod 26, a first spring 27, a positioning tooth groove 28, and a second connecting... Plate 29, second rotating groove 210, and positioning groove 211. The bottom of the first connecting plate 21 is fixedly connected to the outer surface of the upper end of the pre-embedded base 1. The inner surface of the outer surface at the four corners of the upper end of the first connecting plate 21 is provided with first rotating grooves 22. The inner surface of each of the four sets of first rotating grooves 22 is hinged to a rotating positioning rod 23. The outer surface of the upper end of each of the four sets of rotating positioning rods 23 is fitted with a positioning sleeve 24. The outer surfaces of both sides of the positioning sleeve 24 are fixedly connected with movable sleeves 25. The inner surface of the movable sleeve 25 is fitted with an insertion rod 26. The outer surface of the insertion rod 26 is fitted with a first spring 27. The outer surfaces of the upper ends of the four sets of rotating positioning rods 23 are fitted with positioning sleeves 24. The outer surfaces of both sides of the upper end of the positioning sleeve 24 are fixedly connected with movable sleeves 25. The inner surface of the movable sleeve 25 is fitted with an insertion rod 26. The outer surface of the insertion rod 26 is fitted with a first spring 27. The inner surface of each surface is provided with positioning grooves 28, and multiple sets of positioning grooves 28 are provided. The outer surface of the upper end of the first connecting plate 21 is attached to the second connecting plate 29, and the inner surface of the outer surface at the four corners of the second connecting plate 29 is provided with second rotating grooves 210. The inner surface of the upper end of each of the four sets of second rotating grooves 210 is provided with positioning grooves 211. The outer surface of the upper end of the second connecting plate 29 is fixedly connected to the upright rod 3. The outer dimension of one end of the rotating positioning rod 23 is adapted to the inner dimension of the first rotating groove 22 and the second rotating groove 210. The outer surface of the upper end of the rotating positioning rod 23 is fixedly connected to the limit ring, and the outer surfaces of both ends of the limit ring are fixed. The positioning sleeve 24 is connected to a guide block, and guide grooves are provided on the inner walls of both sides. The inner dimensions of the guide grooves are adapted to the outer dimensions of the guide block. This design ensures that the rotating positioning rod 23 is not blocked by the first rotating groove 22 and the second rotating groove 210 when it moves inside them. This design also makes the positioning sleeve 24 more stable when it moves on the outer surface of the rotating positioning rod 23, and prevents the positioning sleeve 24 from detaching from the upper outer surface of the rotating positioning rod 23. It also prevents the positioning sleeve 24 from deflecting when it moves on the outer surface of the rotating positioning rod 23.

[0021] A limiting block is fixedly connected to the outer surface of the insertion rod 26. The two ends of the first spring 27 abut against the surface of one side of the limiting block and the inner wall surface of the movable sleeve 25, respectively. A positioning block is fixedly connected to the outer surface of one end of the insertion rod 26. The internal dimensions of the positioning tooth groove 28 are adapted to the external dimensions of the positioning block. The external dimensions of the positioning sleeve 24 are adapted to the internal dimensions of the positioning groove 211. This design allows the insertion rod 26 to automatically reset under the elasticity of the first spring 27 after moving inside the movable sleeve 25. This allows the positioning block to be inserted into the positioning tooth groove 28 at the corresponding position, positioning the position of the positioning sleeve 24 on the outer surface of the rotating positioning rod 23. This design makes the positioning block more stable when inserted into the positioning tooth groove 28. At the same time, this design makes the positioning sleeve 24 more stable when inserted into the positioning groove 211, and positions the position between the first connecting plate 21 and the second connecting plate 29.

[0022] Example 2, as Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: the replacement structure 4 includes a grid frame 41, a mounting groove 42, a movable groove 43, a locking plate 44, a second spring 45, and a limiting plate 46. A mounting groove 42 is provided inside the outer surface of one side of the grid frame 41, and movable grooves 43 are provided inside the inner walls on both sides of the upper end of the mounting groove 42. Locking plates 44 are engaged inside both sets of movable grooves 43, and a second spring 45 is provided inside both sets of movable grooves 43. The lower end of the mounting groove 42... A limiting plate 46 is fixedly connected to the wall surface. A mesh 5 is inserted into the inside of the mounting groove 42. The internal dimensions of the mounting groove 42 and the external dimensions of the mesh 5 are matched. Rectangular blocks are fixedly connected to the inner wall surfaces on both sides of the movable groove 43. Rectangular grooves are opened inside the outer surfaces on both sides of the locking plate 44. The internal dimensions of the rectangular grooves and the external dimensions of the rectangular blocks are matched. The two ends of the second spring 45 abut against the inner wall surface of the movable groove 43 and the outer surface of the upper end of the locking plate 44, respectively. The outer surface of the inner side of the limiting plate 46 is inclined.

[0023] In this embodiment, the design makes the mesh 5 more stable when inserted into the mounting groove 42, and the design can prevent the locking plate 44 from detaching from the movable groove 43 when it moves inside the movable groove 43. At the same time, the design allows the locking plate 44 to automatically reset under the elasticity of the second spring 45 after it moves inside the movable groove 43, so that the locking plate 44 fits against the outer surface of the mesh 5. Then, the position of the mesh 5 inside the mounting groove 42 can be positioned by the cooperation of the limiting plate 46.

[0024] The two sets of locking plates 44 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0025] Working principle: When using the equipment, first select an appropriate number of sets of equipment. By pre-burying the pre-embedded base 1 underground, the second connecting plate 29 can be placed on the outer surface of the upper end of the first connecting plate 21. Then, the positions of the first rotating groove 22 and the second rotating groove 210 can be aligned. Next, the two sets of insertion rods 26 can be pulled outwards, causing the positioning block at one end of the insertion rod 26 to disengage from the interior of the positioning tooth groove 28. At this time, the position of the positioning sleeve 24 can be moved upwards on the outer surface of the rotating positioning rod 23, thus avoiding obstruction of the rotation of the rotating positioning rod 23 by the positioning sleeve 24. Then, the rotating positioning rod 23 can be hinged and inserted into the interior of the second rotating groove 210. At this time, the positioning sleeve 24 can be moved downwards, causing the lower end of the positioning sleeve 24 to be inserted into the interior of the positioning groove 211. The positioning block then adjusts the position of the positioning sleeve 24 on the outer surface of the rotating positioning rod 23. The first connecting plate 21 and the second connecting plate 29 are positioned by positioning. Then, the upper and lower connecting pins at both ends of the grid frame 41 are inserted into the two sets of connecting rings that are close to each other on one side, thereby connecting multiple sets of grid frames 41 and uprights 3. Next, the two sets of locking plates 44 are moved upward so that the lower ends of the two sets of locking plates 44 are stored in the movable groove 43. At this time, the mesh 5 can be pulled out. Then, the mesh 5 can be inserted into the mounting groove 42 and the limiting plate 46. Then, the two sets of locking plates 44 can be released so that the locking plates 44 reset themselves under the elasticity of the second spring 45, and the lower ends of the locking plates 44 are attached to the outer surface of the mesh 5 to complete the installation of the mesh 5. When the mesh 5 needs to be replaced, the above process can be reversed to disassemble the mesh 5 and reinstall it. The above is the entire working principle of this utility model.

[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0027] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0028] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. 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.
