[0032] 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.

[0033] Reference Figures 1-3 The present invention provides an embodiment of a protective device for engineering construction, comprising a housing 1. The housing 1 is the main body of the guardrail used in construction, which is the prior art known to those skilled in the art and will not be described in detail here. A connecting mechanism 2 is provided on the outer wall of the housing 1. The connecting mechanism 2 is provided on both outer walls of the housing 1. The housing 1 and the rotating mechanism 3 can be fixed conveniently and quickly through the connecting mechanism 2, without the need for disassembly and installation by rotating bolts, which is more convenient and quick.

[0034] Reference Figures 2-3 The connecting mechanism 2 includes a connecting block 201, which is fixedly connected to the outer walls of both sides of the housing 1. A long rod 202 is elastically connected to the inner wall of the top of the connecting block 201 via a spring A203. One end of the spring A203 is fixedly connected to the outer wall of the long rod 202, and the other end is fixedly connected to the inner wall of the top of the connecting block 201. When not affected by external force, the spring A203 drives the long rod 202 to remain in an upward pop-out state due to its own elastic force. Two sets of locking blocks 204 are fixedly connected to the outer wall of the connecting block 201. The positions of the locking blocks 204 on the connecting blocks 201 on the left and right sides of the housing 1 are not corresponding, so that the angle between the housings 1 can be adjusted by rotation after installation.

[0035] Reference Figures 2-3Two sets of wedges 206 are slidably connected to the inner wall of the locking block 204. The two sets of wedges 206 are elastically connected by a spring B205. Both ends of the spring B205 are fixedly connected to the outer wall of the wedges 206. The two sets of wedges 206 are kept in a popped-out state to both sides due to the elastic force of the spring B205. A fixed rod 208 is hinged to the bottom outer wall of the wedges 206 through a rotating rod 207. During the up and down movement of the fixed rod 208, the rotating rod 207 can be rotated, thereby causing the two sets of wedges 206 to move simultaneously to the middle or to both sides. One end of the rod 207 is hinged to the outer wall of the fixed rod 208, and the other end of the rotating rod 207 is hinged to the outer wall of the wedge block 206. The outer walls of the rotating rod 207 and the fixed rod 208 slide in the inner wall of the locking block 204. When there is no external force, the spring A203 drives the long rod 202 to keep moving upward. The long rod 202 drives the two sets of fixed rods 208 to move upward and keeps the outer wall of its top end in contact with the inner wall of the connecting block 201. Thus, the two sets of wedge blocks 206 can be kept in a state of popping out to both sides by rotating the rod 207.

[0036] Reference Figures 2-3 The fixed rod 208 is fixedly connected to the outer wall of the long rod 202. The inner wall of the connecting block 201 has a groove that matches the movement stroke of the fixed rod 208. The operator can press the long rod 202 downward to drive the fixed rod 208 downward. When the long rod 202 rebounds upward due to the elastic force of the spring A203, it can drive the fixed rod 208 upward. The outer wall of the locking block 204 is locked with a limit component. The limit component can connect and fix the housing 1 and the rotating mechanism 3. The outer wall of the locking block 204 is locked with the rotating mechanism 3 through the limit component. The rotating mechanism 3 is the main body of the column between the guardrails. It can connect the two sets of housings 1 and can rotate the housing 1 to adjust the angle of the guardrail combination to adapt to different construction ranges.

[0037] Reference Figures 2-3 The limiting component includes a fixing block 209, which is disposed on both sides of the rotating mechanism 3. Two sets of fixing blocks 209 are provided on each side, and the fixing blocks 209 correspond to the positions of the locking blocks 204. The outer wall of the fixing block 209 is provided with two sets of locking grooves 210. When the wedge 206 engages with the locking groove 210, the housing 1 and the fixing block 209 can be fixed. By pressing down the long rod 202, the wedge 206 is moved to the middle, so that the wedge 206 in both sets of locking blocks 204 can disengage from the locking grooves 210, making disassembly more convenient.

[0038] Reference Figures 4-5The rotating mechanism 3 includes a circular block A301. The inner wall of the circular block A301 is elastically connected to a pull rod 303 via a spring C302. When not affected by external force, the spring C302 drives the circular block A301 to remain in a downward pop-out state due to its own elastic force. When the pull rod 303 is pulled upward, the spring C302 is compressed by force. One end of the spring C302 is fixedly connected to the inner wall of the circular block A301, and the other end of the spring C302 is fixedly connected to the outer wall of the pull rod 303. The outer wall of the pull rod 303 is slidably connected to the inner wall of the circular block A301. In the stationary state, the pull rod 303 drives the protrusion 310 to engage with the groove 311, thereby fixing the circular block A301 and the rotating block A304.

[0039] Reference Figures 4-5 A protrusion 310 is fixedly connected to the bottom outer wall of the pull rod 303. When the pull rod 303 is pulled upward, the protrusion 310 can disengage from the groove 311, thereby rotating the rotating block A304. The rotating block A304 is rotatably connected to the bottom outer wall of the round block A301. The rotating block A304 is fixedly connected to the outer wall of the fixed block 209. The fixed block 209 on the right side of the rotating mechanism 3 is fixedly connected to the outer walls of the rotating block A304 and the rotating block B307. Multiple sets of grooves 311 are opened on the top inner wall of the rotating block A304. The protrusion 310 is engaged with the groove 311, thereby fixing the rotating mechanism 3 as a whole, preventing the rotating block A304 and the rotating block B307 from rotating, and fixing the angle between the housing 1.

[0040] Reference Figures 4-5 A connecting rod 306 is fixedly connected to the bottom outer wall of the rotating block A304, and a rotating block B307 is fixedly connected to the bottom outer wall of the connecting rod 306. The rotating block A304 and the rotating block B307 are connected as one unit through the connecting rod 306. When the pull rod 303 is pulled upward to make the rotating block A304 rotate, it can drive the rotating block B307 to rotate synchronously, thereby driving the housing 1 on the right side of the rotating mechanism 3 to rotate at a certain angle. A circular block B305 is rotatably connected to the bottom outer wall of the rotating block A304. The bottom outer wall of the circular block B305 is rotatably connected to the top outer wall of the rotating block B307. The outer wall of the connecting rod 306 is in contact with the inner wall of the circular block B305. When the rotating block A304 and the rotating block B307 rotate, the circular block B305 is in a fixed state.

[0041] Reference Figures 4-5A base 309 is rotatably connected to the bottom outer wall of the rotating block B307. The base 309 can be fixed to the ground with bolts to improve the fixing effect. A reinforcing rod 308 is fixedly connected to the outer wall of the base 309. The reinforcing rod 308 is fixedly connected to the outer walls of the round blocks B305 and A301. The reinforcing rod 308 can fix the round blocks B305 and A301 to the base 309. Thus, when the rotating block A304 and the rotating block B307 rotate, the above three remain in a fixed state, so that the angle between the two sets of housings 1 can be adjusted.

[0042] Working principle: When installing the housing 1, the two sets of locking blocks 204 on one side of the housing 1 can be aligned with the positions of the fixing blocks 209. Then, the housing 1 is moved so that the locking blocks 204 move inward along the inner wall of the fixing blocks 209. The arc surface of the wedge block 206 is pressed inward along the inner wall of the locking blocks 204 by the force of the outer wall of the fixing blocks 209. When the locking blocks 204 are completely moved into the interior of the fixing blocks 209, the wedge block 206 pops outward due to the elastic force of the spring B205 and engages with the locking groove 210, thus fixing the housing 1 to the rotating mechanism 3. Then, the other set of housing 1 is fixed in the two sets of fixing blocks 209 on the left side of the rotating mechanism 3, thus completing the installation between the housing 1s conveniently and quickly.

[0043] After the housing 1 and the rotating mechanism 3 are installed, the angle between the housing 1 can be adjusted according to the construction site to adapt to different construction environments. At this time, the operator can pull the pull rod 303 upward to disengage the protrusion 310 from the groove 311, and then rotate the housing 1 on the right side of the rotating mechanism 3, causing the rotating block B307, the connecting rod 306 and the rotating block A304 to rotate synchronously. At this time, since the base 309, the round block B305 and the round block A301 are fixed by the reinforcing rod 308 and cannot rotate, the angle between the two sets of housing 1 can be adjusted. When the appropriate angle is adjusted, the pull rod 303 can be released, and the pull rod 303 will pop down due to the elastic force of the spring C302. The protrusion 310 and the groove 311 will engage, thus fixing the rotating block A304. The rotating block B307 will be fixed by the connecting rod 306, thus fixing the two sets of housing 1.

[0044] When it is necessary to disassemble the housing 1, the long rod 202 can be pressed down, the spring A203 will contract and drive the two sets of fixing blocks 209 to move downward. The fixing blocks 209 drive the rotating rod 207 to flip, and the rotating rod 207 drives the wedge block 206 to move towards the middle at the same time. The spring B205 is compressed and the wedge block 206 can be disengaged from the slot 210, thereby releasing the two sets of locking blocks 204 from the fixing blocks 209. The housing 1 can be removed quickly and easily without having to disassemble and install it by turning the bolts multiple times, which is more time-saving and labor-saving.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
