Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for municipal engineering, and more specifically, to a road foundation pit enclosure device. Background Technology

[0002] During road construction, foundation pit fencing is a crucial facility for isolating the construction area and ensuring on-site safety and pedestrian / vehicle traffic order. Its performance directly affects construction efficiency and safety. Traditional foundation pit fencing often uses a fixed frame structure, assembled by bolts or welding. Installation and disassembly require tools, making the process cumbersome and time-consuming, and difficult to adapt to the rapid deployment needs of temporary construction scenarios.

[0003] Existing fencing generally suffers from insufficient ventilation. The enclosed structure easily leads to pressure differences between the inside and outside, making it prone to tipping over in strong winds. At the same time, the spliced ​​fencing is rigid and has poor adaptability. It cannot adjust its angle according to the terrain, and the connection between the support rods and the main body of the fencing is not stable enough. It is prone to loosening after long-term use, posing a safety hazard. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-2 As shown, the road pit enclosure device according to an embodiment of the present utility model includes an enclosure structure 1, connecting structures 2 on both sides of the enclosure structure 1, a sealing structure 3 connected to the enclosure structure 1, a fixing structure 4 on one side of the sealing structure 3, and a support rod 5 matched to the connecting structure 2. The enclosure structure 1 achieves convenient docking function through the support rod 5 and the connecting structure 2, and the connecting structure 2 achieves convenient disassembly and installation function through the sealing structure 3 and the fixing structure 4.

[0026] like Figure 3 As shown, the enclosure structure 1 includes an installation frame 101, a breathable net 102, a fitting groove 103, a rotating groove 104, a support leg 105, and a support base 106. The breathable net 102 is installed inside the installation frame 101. Fitting grooves 103 are provided at both ends of the installation frame 101. A rotating groove 104 is provided on one side of the fitting groove 103 on the installation frame 101. The support leg 105 is fixedly connected to the bottom end of the installation frame 101, and the support base 106 is rotatably connected to the support leg 105.

[0027] The enclosure structure 1 serves as the main body of the device, with its mounting frame 101 providing a support frame for the whole. The breathable net 102 inside the frame allows for gas circulation, effectively balancing the air pressure inside and outside the enclosure and avoiding the risk of tipping over due to pressure difference. The fitting groove 103 and rotating groove 104 at both ends of the mounting frame 101 provide the installation foundation for the fixed structure 4 and the sealing structure 3, respectively. The support leg 105 at the bottom cooperates with the rotatably connected support base 106, which can adapt to different ground flatness and enhance the overall stability.

[0028] likeFigures 4-5 As shown, the connecting structure 2 includes a guide rod 201, a connecting block 202, a mating block 203, a through rod 204, a through hole 205, and a guide block 206. The guide rod 201 is slidably connected to the guide block 206, and the connecting block 202 is fixedly connected to the guide block 206. The connecting block 202 has a through hole 205, and the connecting block 202 is connected to the mating block 203. The mating block 203 is fixedly provided with the through rod 204, and the through rod 204 matches the through hole 205. An arc groove that fits the support rod 5 is formed between the connecting block 202 and the mating block 203.

[0029] The connecting structure 2 is used to achieve quick docking of the enclosure structure 1. The guide rod 201 is fixed on both sides of the mounting frame 101. The guide block 206 slides along the guide rod to drive the connecting block 202 to adjust its position. The two guide blocks on one guide rod connect two sets of connecting components respectively to ensure docking flexibility. The docking block 203 matches the through hole 205 of the connecting block 202 through the through rod 204 to form a detachable connection. After the support rod 5 passes through the arc groove between the two, it is fixed by the fixing structure 4. When the two sets of enclosures are docked, the connecting block 202 and the docking block 203 are placed alternately, which can realize the relative rotation between the enclosures and improve the splicing adaptability.

[0030] like Figure 6 As shown, the sealing structure 3 includes a sealing block 301 and a rotating shaft 302. The sealing block 301 is connected to the rotating shaft 302, and the sealing block 301 is rotatably connected to the rotating groove 104 through the rotating shaft 302.

[0031] Continue as Figure 6 As shown, the fixing structure 4 includes a fixing block 401, a fixing hole 402, and a fitting block 403. The fixing block 401 has a fixing hole 402, and the fitting block 403 is integrally provided on one side of the fixing block 401. The fitting block 403 fits into the fitting groove 103.

[0032] The fixing structure 4 is embedded in the fitting groove 103 of the mounting frame 101 by the fitting block 403 of the fixing block 401, and the fixing hole 402 is for the end of the support rod 5 to pass through, so as to achieve the initial positioning of the support rod; the top fixing block further reinforces the support rod, forming a two-point fixation. The sealing block 301 of the sealing structure 3 rotates in the rotating groove 104 through the rotating shaft 302. After the fixing block is installed, rotating the sealing block to the end of the fixing block can prevent the fixing block from sliding out of the fitting groove and enhance the structural stability. The two work together to achieve convenient installation and anti-detachment fixation of the support rod.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] The enclosure structure 1 is easily connected via the connecting structure 2 and the support rod 5. The sealing structure 3 and the fixing structure 4 fix and easily disassemble the support rod 5. The breathable net 102 on the mounting frame 101 of the enclosure structure 1 facilitates gas flow and prevents the enclosure from tipping over due to pressure difference. The guide rod 201 of the connecting structure 2 is fixedly installed on both sides of the mounting frame 101. The connecting block 202 can slide on the guide rod 201 via the guide block 206. Two guide blocks 206 are slidably connected on one guide rod 201. The docking block 203 is easily connected to the connecting block 202 via the through rod 204. The support rod 5 passes through the connecting block 202 and the docking block 203 to form an arc groove. The fixing block 401 is fitted into the mating groove 103 at the bottom of the mounting frame 101 via the fitting block 403. One end of the support rod 5 is connected to the fixing hole 402, which serves to support the support rod 5. After initial fixation, the fixing block 401 at the top of the mounting frame 101 is installed to completely fix the support rod 5. Then, the sealing block 301 of the sealing structure 3 is rotated so that the sealing block 301 rotates to one end of the fixing block 401, which prevents the fixing block 401 from sliding out of the mating groove 103. When the two enclosure structures 1 are connected, since the connecting block 202 and the mating block 203 of the connecting structure 2 are detachable, the connecting block 202 of the enclosure structure 1 to be connected can be mated on the support rod 5 of the other enclosure structure 1 first. The connecting blocks 202 of the connecting structures 2 of the two enclosure structures 1 are placed alternately, which can better stabilize the connection. After the connecting block 202 is mated, the connection structure 2 and the support rod 5 are connected by the mating block 203, completing the connection of the two enclosure structures 1. The enclosure structures 1 can rotate relative to each other.
