[0001] The utility model belongs to the technical field of municipal engineering, and particularly relates to a quickly assembled protective net for municipal engineering. Background Art

[0002] The protective net for municipal engineering generally refers to a temporary enclosure facility used in municipal engineering projects such as urban construction, road construction, bridge maintenance, and underground pipeline laying for isolating and protecting the safety of the construction site.

[0003] A protective net that is easy to assemble with the authorization announcement number of CN 217380031 U includes a first upright post. A second upright post with a symmetric structure is arranged on the left side of the first upright post, and the first upright post and the second upright post have the same structure. The bottom ends of the first upright post and the second upright post are detachably connected to a base through a connecting seat. First connecting pieces are welded to the upper and lower ends on the outer sides of the first upright post and the second upright post, and second connecting pieces are welded to the upper and lower ends on the inner sides of the first upright post and the second upright post. In the utility model, the upright posts are connected by a baffle, and the number of baffles can be installed between the two upright posts according to requirements. Moreover, the upright post and the baffle can be rotatably connected according to the connecting piece, and the angle can be adjusted according to requirements, so the applicable range is relatively wide. The upright post and the baffle are installed and rotatably connected through the connecting piece, and the two connecting pieces are fixed and disassembled by bolts, which is convenient for assembly and disassembly and is more convenient for transportation.

[0004] Although the current protective net assembly scheme can meet the basic requirements, some inconveniences are exposed in actual applications. The method of fixing and disassembling with bolts is relatively cumbersome and time-consuming, reducing the operation efficiency. In addition, every time the angle of the protective net needs to be adjusted, the bolts need to be repeatedly disassembled and assembled, resulting in poor efficiency and flexibility when adjusting the relative angle between the protective nets. Content of the Utility Model

[0005] In view of this, the utility model provides a quickly assembled protective net for municipal engineering, which can cooperate with a quick assembly mechanism and a driving component, so that the protective net for municipal engineering can be quickly and conveniently assembled together without cumbersome bolt disassembly and assembly steps, improving the operation efficiency, and can more conveniently adjust the relative angle between the protective nets according to needs, significantly improving the operation efficiency and flexibility.

[0006] To solve the above technical problems, the utility model provides a quickly assembled protective net for municipal engineering, which includes a protective net frame and quickly assembled mechanisms arranged at the left and right ends of the protective net frame. The quickly assembled mechanism includes a limiting plate arranged on the left surface of the protective net frame, and a limiting boss is arranged on the right surface of the protective net frame. The protective net frame provides fixed support for the limiting plate and the limiting boss. Sliding limiting columns are slidably connected in the sliding holes arranged at the upper and lower ends of the limiting boss. The sliding holes provide sliding guidance for the sliding limiting columns. Limiting groove holes are arranged on the upper and lower wall surfaces of the limiting plate, and a driving component for driving the sliding limiting columns to move is further arranged in the limiting boss.

[0007] The quickly assembled mechanism further includes locking grooves respectively arranged annularly and evenly at the outer end heads of the sliding limiting columns, and locking protrusions are arranged annularly and evenly at the inner cavity ends of the limiting groove holes, which play a role in locking and limiting.

[0008] The quickly assembled mechanism further includes annular plates respectively arranged at the outer end heads of the sliding limiting columns. Fixed plates are arranged symmetrically vertically at the upper and lower ends of the inner cavity of the limiting boss. Through holes adapted to the sliding limiting columns are arranged in the middle of the fixed plates. Springs are arranged on the outer side surfaces facing away from each other of the two fixed plates. The outer end heads of the springs are respectively fixedly connected to the inner end surfaces of the adjacent annular plates on the same side. The springs are respectively sleeved on the outside of the sliding limiting columns on the same side, providing elastic support for the sliding limiting columns.

[0009] The driving component includes a rotating column rotatably connected to the middle of the limiting boss. A gear is arranged in the middle of the rotating column. Connecting plates are arranged at the inner end heads of the sliding limiting columns. Tooth pressing plates are arranged on the inner side surfaces of the two connecting plates near the gear. The two tooth pressing plates are both meshed with the gear; the driving component further includes a handle arranged at the front extending end of the rotating column, and a limiting component is further arranged at the lower end of the handle for driving the sliding limiting columns to move.

[0010] The limiting component includes a movable column movably inserted into the socket at the lower end of the handle. The socket provides movable support for the movable column; the limiting component further includes a limiting circular groove arranged on the front surface of the limiting boss. The movable column is arranged in cooperation with the limiting circular groove for limiting the handle. The arc movement track of the movable column coincides with the limiting circular groove.

[0011] The beneficial effects of the above technical solutions of the utility model are as follows:

[0012] 1. Place multiple protective wire meshes properly and make the adjacent ends of two adjacent protective wire meshes close to each other. Ensure that the limit plate fits with the limit boss of another protective wire mesh. Then, the relevant staff member pulls the movable column outwards to separate it from the limit circular groove. After that, the sliding limit column, connecting plate, annular plate, and locking groove will immediately reset under the action of the spring's resilience and be inserted into the corresponding limit slot holes movably, and the locking groove will engage with the corresponding locking bump to form a stable connection, preventing dislocation caused by external forces after assembly, enabling the protective wire mesh for municipal engineering to be assembled quickly and conveniently without the cumbersome steps of bolt disassembly and assembly. Repeating the above operations multiple times can achieve the assembly of multiple groups of protective wire meshes, improving the operation efficiency.

[0013] 2. When the angle needs to be adjusted, turn the handle again through the movable column, successively causing the sliding limit column to retract and avoid separation from the limit circular groove, enabling the relative angle between the protective wire meshes to be adjusted more conveniently according to needs, significantly improving the operation efficiency and flexibility.

[0014] 3. First, the relevant staff member turns the handle successively through the movable column. The rotation of the handle drives the rotating column and the gear to rotate accordingly. When the gear rotates, it drives the connecting plate, sliding limit column, annular plate, and locking groove to move inwards synchronously against the spring's resilience through the tooth pressure plate meshed with it, so that the sliding limit column retracts and avoids. After the movable column moves to correspond to the limit circular groove, press on the movable column to insert the movable column into the limit circular groove, thereby limiting the adjusted sliding limit column.

The fixing plates 205 are fixedly installed at the upper and lower ends of the inner cavity of the limit boss 201. Through holes adapted to the sliding limit columns 202 are arranged in the middle of the fixing plates 205. Springs 206 are arranged on the outer side surfaces of the two fixing plates 205 facing away from each other. The outer ends of the springs 206 are respectively fixedly connected to the inner end surfaces of the adjacent annular plates 204 on the same side. The springs 206 are respectively sleeved on the outside of the sliding limit columns 202 on the same side adjacent to them, providing elastic support for the sliding limit columns 202.

[0024] As shown Figures 1-4 in the figure, the driving assembly includes a rotating column 300 rotatably connected to the middle of the limiting boss 201. A rotating hole for providing rotational support to the rotating column 300 is provided in the middle of the limiting boss 201. A gear 301 is provided in the middle of the rotating column 300. The gear 301 is arranged in the middle of the outer arc surface of the rotating column 300 and is located in the middle of the inner cavity of the limiting boss 201. The limiting boss 201 provides rotational support for the rotating column 300. Connecting plates 302 are provided at the inner ends of the sliding limiting columns 202.

[0025] As shown Figures 1-4 in the figure, the limiting assembly includes a movable column 400 movably inserted into the socket at the lower end of the handle 304. The socket provides movable support for the movable column 400. The movable column 400 is located in the socket; the limiting assembly further includes a limiting circular groove 401 provided on the front surface of the limiting boss 201. The limiting circular groove 401 is provided on the limiting boss 201. The movable column 400 is cooperatively arranged with the limiting circular groove 401 for limiting the handle 304. The arc-shaped movement track of the movable column 400 coincides with the limiting circular groove 401.

[0026] The working principle of a quickly assembled protective net for municipal engineering provided by the utility model is as follows: First, relevant staff members rotate the handle 304 through the movable column 400 in sequence. When the handle 304 rotates, the rotating column 300 and the gear 301 rotate accordingly. When the gear 301 rotates, it drives the connecting plate 302, the sliding limit column 202, the annular plate 204, and the locking groove 207 to move synchronously inward against the elastic force of the spring 206 through the tooth pressing plate 303 engaged with it, so that the sliding limit column 202 retracts and gives way. After the movable column 400 moves to correspond to the limit circular groove 401, press on the movable column 400 to insert the movable column 400 into the limit circular groove 401, thereby limiting the adjusted sliding limit column 202. Then, place multiple protective net frames 100, and make the adjacent ends of two adjacent protective nets approach each other, ensuring that the limit plate 200 fits with the limit boss 201 of another protective net. Then, relevant staff members pull the movable column 400 outward to separate it from the limit circular groove 401. After that, the sliding limit column 202, the connecting plate 302, the annular plate 204, and the locking groove 207 immediately reset under the action of the return elastic force of the spring 206 and are movably inserted into the corresponding limit slot holes 203, and the locking groove 207 will be buckled with the corresponding locking protrusion 208 to form a stable connection, preventing dislocation caused by external forces after assembly, enabling the protective net for municipal engineering to be quickly and conveniently assembled together without cumbersome bolt disassembly and assembly steps. Repeating the above operations multiple times can achieve the assembly of multiple groups of protective nets, improving the operation efficiency. When the angle needs to be adjusted, rotate the handle 304 through the movable column 400 again to make the sliding limit column 202 retract and give way and separate from the limit circular groove 401 in sequence, and the relative angle between the protective nets can be adjusted more conveniently according to needs, significantly improving the operation efficiency and flexibility.

[0027] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
