Description

Technical Field

[0001] This utility model relates to the field of park security technology, and in particular to a protective net for park security that is easy to assemble and disassemble. Background Technology

[0002] Park security mainly consists of three parts: physical security, technical security, and human security. Physical security refers to the use of physical facilities to build security barriers to block or delay risk intrusion. It is the basic line of defense for security. Protective nets are a type of physical security facility that can be used to separate construction areas within the park to prevent unauthorized personnel from accidentally entering the construction area.

[0003] Because the width of a single protective net is limited, in practical applications, multiple protective nets are usually assembled by connecting them end to end, as disclosed in the utility model patent with authorization announcement number CN222228180U. However, when connecting the ends of the current protective nets, it is mostly necessary to lift one side of the protective net so that the insert on it can be inserted into the support plug on the other side of the protective net. Since the protective net also includes relatively heavy structures such as bases and uprights, it is relatively inconvenient to lift it for operation, which affects the efficiency of disassembly and assembly and is also more labor-intensive.

[0004] Therefore, it is necessary to invent a protective net for park security that is easy to assemble and disassemble to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a park security net that is easy to assemble and disassemble. It can facilitate the assembly and disassembly of two adjacent devices without lifting the heavy housing components, reducing the difficulty of use and saving manpower. It is more convenient to use in practice, thus solving the problem mentioned in the background art that when connecting the ends of the current security net, it is mostly necessary to lift one side of the security net so that the insert on it can be inserted into the support plug on the other side of the security net. Since the security net also includes relatively heavy structures such as the base and uprights, it is relatively inconvenient to lift it for operation, which affects the efficiency of assembly and disassembly and is also more labor-intensive.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a protective net for park security that is easy to assemble and disassemble, comprising:

[0007] A housing assembly that provides a mounting base for a retractable protective assembly;

[0008] A retractable protective assembly, the retractable protective assembly being deployed to form a barrier protection; and

[0009] The handheld connecting assembly includes a traction sleeve fixedly connected to the right end of the protective net body. A fixing frame is fixedly sleeved on the top outer side of the traction sleeve, and a grip handle is fixedly sleeved on the top inner side of the fixing frame. A limiting hole with interference fit to a limiting bolt is opened on the top left side of the fixing frame. A T-shaped slide rod is slidably arranged on the inner side of the traction sleeve along the vertical direction through a linear bearing. A return spring is fixedly sleeved on the top outer side of the T-shaped slide rod and fixedly connected between the top of the traction sleeve and the T-shaped slide rod. Two T-shaped inserts are fixedly arranged from top to bottom on the right side of the T-shaped slide rod.

[0010] According to at least one embodiment of the present disclosure, a park security net that is easy to assemble and disassemble has two limiting grooves on the right side of the traction sleeve, and the two T-shaped inserts are respectively slidably disposed inside the two T-shaped inserts in the vertical direction.

[0011] According to at least one embodiment of the present disclosure, a park security net that is easy to assemble and disassemble includes a receiving component comprising a support base, wherein a plurality of fixing holes are evenly provided on the top of the support base.

[0012] According to at least one embodiment of the present disclosure, a protective net for park security that is easy to assemble and disassemble is provided, wherein a columnar shell is fixedly provided at the top center of the support base, an access channel is provided on the right side of the columnar shell, and two support plugs are fixedly provided from top to bottom on the left side of the columnar shell.

[0013] According to at least one embodiment of the present disclosure, a campus security protective net that is easy to assemble and disassemble includes a retractable protective assembly comprising a rotating shaft rotatably disposed inside a columnar housing via a bearing, wherein a protective net body is wound around the outside of the rotating shaft and the left end of the protective net body is fixedly connected to the outer wall of the rotating shaft.

[0014] According to at least one embodiment of the present disclosure, a park security net that is easy to assemble and disassemble is provided, wherein a manual turntable is fixedly connected to the top of the rotating shaft, and a limit bolt is provided through the top right side of the manual turntable in a vertical direction, and the limit bolt is screwed to the manual turntable.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a handheld connecting component. When unfolding the protective net body, the user can grip the handle and move the fixing frame and traction sleeve. The traction sleeve pulls the protective net body, which is wound around the outside of the rotating shaft, causing it to unfold horizontally. When the two T-shaped inserts approach the two adjacent support components, gripping the handle and pulling the T-shaped slide rod upwards causes the two T-shaped inserts to rise, simultaneously stretching the return spring. At this point, the two T-shaped inserts avoid the two support components. As the protective net body continues to unfold, the two T-shaped inserts move to the top of the two support components. Releasing the T-shaped slide rod causes the stretched return spring to move the T-shaped slide rod downwards, allowing the two T-shaped inserts to be inserted into the inner side of the two support components, forming a limit. Compared to existing technologies, this invention allows for easier assembly and disassembly of adjacent devices without lifting the heavy receiving components, reducing the difficulty of use and saving manpower, making it more convenient in actual use.

[0027] Figure 2 This is a schematic diagram of the structure of a detachable and retractable protective net for park security, according to one embodiment of the present disclosure, comprising a receiving component 1 and a retractable protective component 2.

[0028] Figure 3 This is a schematic diagram of the structure of a handheld connecting component 3 for a park security protective net that is easy to assemble and disassemble, according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the easily detachable and assembleable protective net for park security disclosed herein may include components such as: a housing component 1, a rollable protective component 2, and a handheld connecting component 3.

[0030] like Figure 2 As shown in this disclosure, the housing component 1 includes a support base 11 made of Q235 carbon steel, which bears the weight of the entire device and is connected to the ground through fixing holes 12 to ensure the overall stability of the device and prevent it from tipping over. A rubber pad is attached to the bottom to prevent slipping and damping. Multiple fixing holes 12 are evenly distributed on the top of the support base 11. A columnar shell 13 made of galvanized steel plate is fixedly installed at the center of the top of the support base 11 to house the protective net body 22, preventing the net from aging due to sun and rain, and providing installation space for the rotating shaft 21. An access channel 14 is provided on the right side of the columnar shell 13. Two support inserts 15 made of 304 stainless steel are fixedly installed on the left side of the columnar shell 13 from top to bottom. They cooperate with the T-shaped inserts 36 of the handheld connection component 3 to realize the quick connection of adjacent devices.

[0031] Therefore, during actual installation, multiple bolt holes corresponding to the fixing holes 12 can be opened on the opposite side, and then expansion bolts can be passed through the fixing holes 12 and the bolt holes in sequence to form a stable fixation. In addition, after the protective net body 22 is rolled up, the columnar shell 13 can protect the protective net body 22, thereby extending the service life of the protective net body 22.

[0032] like Figure 2 As shown, in a preferred embodiment, the retractable protective assembly 2 includes a rotating shaft 21 rotatably disposed inside the cylindrical housing 13 via a bearing. A protective net body 22 is wound around the outside of the rotating shaft 21. The net body is made of high-carbon steel warp and weft woven mesh, and the edges of the net body are sewn with polyester edging to prevent the mesh from fraying. The left end is fixed to the rotating shaft 21 by a rivet. A manual turntable 23 made of ABS engineering plastic is fixedly connected to the top of the rotating shaft 21. A limit bolt 24 is provided vertically through the top right side of the manual turntable 23, and the limit bolt 24 is screwed to the manual turntable 23.

[0033] Therefore, in the stored state, the limiting bolt 24 is inserted into the limiting hole 34 to limit the fixing frame 32, thereby causing the fixing frame 32 to drive the traction sleeve 31 to fit against the side of the columnar housing 13, preventing the hand-held connecting component 3 from tipping over. When it needs to be unfolded for use, the limiting bolt 24 is rotated, causing the limiting bolt 24 to move upward on the top of the manual turntable 23 until the limiting bolt 24 moves out from the inside of the limiting hole 34, thereby releasing the limitation on the fixing frame 32. When the unfolded protective net body 22 is subsequently retrieved, the manual turntable 23 can be rotated in any direction, thereby causing the manual turntable 23 to drive the rotating shaft 21 to rotate, at which time the rotating shaft 21 rolls up the protective net body 22.

[0034] like Figure 3As shown in this disclosure, the handheld connecting assembly 3 includes a traction sleeve 31 fixedly connected to the right end of the protective net body 22. The sleeve is made of 6061 aluminum alloy. A fixing frame 32, made of cold-rolled steel plate and in a "U" shape, is fixedly sleeved on the top outer side of the traction sleeve 31. A grip handle 33, made of 45# steel, is fixedly installed on the top inner side of the fixing frame 32. The top of the handle is a circular handheld part. A linear bearing ensures smooth sliding. A limiting hole 34, which is interference-fitted with the limiting bolt 24, is opened on the left side of the top of the fixing frame 32. A T-shaped sliding rod is slidably installed on the inner side of the traction sleeve 31 along the vertical direction via a linear bearing. 35. A return spring 38, made of manganese steel, is fixedly connected to the top of the outer side of the T-shaped slide rod 35 and is fixed between the top of the traction sleeve 31 and the T-shaped slide rod 35. The two ends are welded and fixed to the top of the traction sleeve 31 and the T-shaped slide rod 35 respectively, so that it can automatically return after the T-shaped slide rod 35 is released, ensuring that the T-shaped insert 36 is stably inserted into the support plug 15. Two T-shaped inserts 36 are fixedly arranged from top to bottom on the right side of the T-shaped slide rod 35. Two limiting grooves 37 are opened on the right side of the traction sleeve 31. The two T-shaped inserts 36 are slidably arranged on the inner side of the two T-shaped inserts 36 in the vertical direction respectively.

[0035] Therefore, when unfolding the protective net body 22, the grip handle 33 can be held, and the grip handle 33 can drive the fixed frame 32 and the traction sleeve 31 to move. When the traction sleeve 31 moves, it pulls the protective net body 22 wrapped around the outside of the rotating shaft 21, thereby causing the protective net body 22 to be unfolded horizontally. When the two T-shaped inserts 36 approach the two adjacent bearing inserts 15, the grip handle 33 is held while the T-shaped slide bar 35 is pulled upward, thereby causing the T-shaped slide bar 35 to drive the two T-shaped inserts 36 to rise, and at the same time stretching the return spring 38. At this time, the two T-shaped inserts 36 avoid the two support plugs 15. As the protective net body 22 continues to unfold, the two T-shaped inserts 36 move to the top of the two support plugs 15. At this time, the T-shaped slide bar 35 is released, and the stretched return spring 38 drives the T-shaped slide bar 35 to move down, thereby allowing the two T-shaped inserts 36 to be inserted into the inside of the two support plugs 15 to form a limit. Compared with the existing technology, it is easier to disassemble and assemble two adjacent devices, and there is no need to lift the heavy housing component 1, which reduces the difficulty of use and saves manpower, making it more convenient to use in practice.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
