Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically a temporary edge protection railing. Background Technology

[0002] In the construction of various projects, there are always "four openings and five edges". In order to avoid accidents, safety protection work needs to be done during construction. Therefore, guardrails are needed to protect the construction site.

[0003] A search revealed a utility model patent with Chinese patent publication number CN217602307U, which discloses a temporary guardrail for the edge of a foundation pit. This guardrail is easy to assemble and disassemble, structurally stable, and provides good protection, falling under the technical field of construction guardrails. The temporary guardrail for the edge of the foundation pit includes multiple slots spaced apart along the axis of each upright on its side, with each pair of uprights having corresponding slots. The slots also have limiting grooves on their sides. Inserts are provided at both ends of the retaining plate and at both ends of the crossbar.

[0004] The above-mentioned device achieves the purpose of easy disassembly and transportation by using the uprights and multiple crossbars in conjunction. However, if the area to be protected is long, disassembly and installation will take a lot of time, resulting in low efficiency and room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a temporary edge protection railing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temporary edge protection railing, comprising a plurality of intercepting bars, with the same connecting assembly installed on two adjacent intercepting bars. The connecting assembly includes two connecting pins that slide between the two intercepting bars. A threaded sleeve is coaxially fixed to one of the top connecting pins, and a screw is coaxially fixed to one of the bottom connecting pins. The screw is threadedly connected inside the threaded sleeve, and a retaining ring is coaxially fixed to the bottom of the outer circumference of the screw. The radius of the retaining ring is larger than the radius of the connecting pin.

[0007] The state of the railing can be adjusted according to usage. It can act as a barrier when needed and can also be quickly folded and retracted when not needed. It is simple and convenient to use. If the area to be blocked is long, insert a new barrier into the assembly, and then use the connecting pin at the top to connect the top of the two barrier bars. Then, drive the screw to rotate by the knob. As the screw rotates, it extends outward from the screw sleeve. The connecting pin at the bottom of the screw connects the bottom of the two barrier bars, ensuring that the two barrier bars will not detach while also allowing them to be folded, providing conditions for subsequent retraction.

[0008] As a further preferred embodiment of this technical solution, the outermost interceptor bar is equipped with a storage component, which includes a take-up drum placed on one side of the interceptor bar, a limiting card fixedly connected to the outer circumferential wall of the take-up drum, and the interceptor bar slidably sleeved on the outside of the limiting card.

[0009] As a further preferred embodiment of this technical solution, an installation frame is fixedly connected to the top of the outer circumference of the winding drum, a vertically arranged guide rod is fixedly connected inside the installation frame, a limiting clip is slidably sleeved on the outside of the guide rod, a spring is sleeved on the outside of the guide rod, and the limiting clip is slidably inserted into the top of the intercepting rod.

[0010] Grasp the second limit clamp and pull it upward. The spring stress is overcome and the second limit clamp contracts, allowing it to move upward along the guide rod. Then, first, place one of the guardrail's blocking bars outside the first limit clamp, and then release the restriction of the second limit clamp. The second limit clamp is driven by the spring to engage with the top of the blocking bar, thus completing the connection. Subsequently, the guardrail will be wound around the outside of the winding drum, without taking up too much volume, making it easy to transport.

[0011] As a further preferred embodiment of this technical solution, a support assembly is installed inside the interceptor bar. The support assembly includes a mounting hole opened in the middle of the interceptor bar, a support rod is slidably inserted into the mounting hole, and a support plate is fixedly connected to one end of the bottom of the support rod.

[0012] By rotating the support rod with the handle, the support rod causes the support plate to rotate 90 degrees. With the support plate, the railing will not tip over. When not in use, flip the support plate to make it parallel to the barrier bar, and the railing can be laid flat for retraction.

[0013] As a further preferred embodiment of this technical solution, the top outer wall of the support rod is provided with a through groove, and a handle is hinged to the inner wall of the through groove, and the width of the handle is smaller than the width of the through groove.

[0014] As a further preferred embodiment of this technical solution, the bottom outer wall of the winding drum is equipped with a number of equidistant casters.

[0015] As a further preferred embodiment of this technical solution, each end of the support plate has a vertically arranged through hole.

[0016] This utility model provides a temporary edge protection railing, which has the following beneficial effects:

[0017] (1) This utility model, by setting up a connecting component and a storage component, allows the state of the railing to be adjusted according to the usage situation. It can play an interception role when needed, and can also be quickly folded and gathered when not needed. It is simple and convenient to use. If the interception position is long, insert a new interceptor into the assembly body, and then use the connecting pin at the top to connect the top of the two interceptors. Then, drive the screw to rotate by the knob. The screw rotates and extends outward of the screw sleeve. The connecting pin at the bottom of the screw connects the bottom of the two interceptors, ensuring that the two interceptors will not separate while also being foldable, providing conditions for subsequent gathering work. When not in use, grasp the second limit card and pull it upward. The stress of the spring is overcome and the second limit card can move upward along the guide rod. Then, first put one of the railing's interceptors on the outside of the first limit card, and then release the restriction of the second limit card. The second limit card is driven by the spring to engage with the top of the interceptor, thus completing the connection work. Afterward, the railing will be wound around the outside of the winding drum, without taking up too much volume, making it easy to transport.

[0018] (2) By setting up a support component, the support rod is rotated by the handle, and the support rod drives the support plate to rotate 90 degrees. Under the support of the support plate, the railing will not tilt at will. When not in use, the support plate is flipped to keep it parallel to the barrier bar, and the railing can be laid flat for closing. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, a temporary edge protection railing includes several guardrails 1. Two adjacent guardrails 1 are equipped with the same connecting component 3. The connecting component 3 includes two connecting pins 301 that are slidably inserted between the two guardrails 1. A threaded sleeve 302 is coaxially fixed to one of the top connecting pins 301, and a screw 303 is coaxially fixed to one of the bottom connecting pins 301. The screw 303 is threaded into the inside of the threaded sleeve 302. A retaining ring 304 is coaxially fixed to the bottom of the outer circumference of the screw 303. The radius of the retaining ring 304 is larger than the radius of the connecting pin 301.

[0027] like Figure 4 and Figure 5 As shown, the outermost interceptor bar 1 is equipped with a storage component 5. The storage component 5 includes a take-up drum 501 placed on one side of the interceptor bar 1, and a limit card 502 fixedly connected to the outer circumference of the take-up drum 501. The interceptor bar 1 is slidably sleeved on the outside of the limit card 502.

[0028] A mounting frame 503 is fixedly connected to the top of the outer circumference of the winding drum 501. A vertically arranged guide rod 504 is fixedly connected inside the mounting frame 503. A limit card 505 is slidably sleeved on the outside of the guide rod 504. A spring 506 is sleeved on the outside of the guide rod 504. The limit card 505 is slidably inserted into the top of the interceptor rod 1.

[0029] If the interception position is relatively long, insert the new interceptor rod 1 into the assembly body, and then connect the tops of the two interceptor rods 1 using the connecting pin 301 at the top. Then, drive the screw 303 to rotate by the knob. The screw 303 rotates and extends outward towards the screw sleeve 302. The connecting pin 301 at the bottom of the screw 303 connects the bottoms of the two interceptor rods 1, ensuring that the two interceptor rods 1 will not detach while also allowing them to be folded, providing conditions for subsequent retraction. When not in use, grasp the second limit card 505 and pull it upward. The stress of the spring 506 is overcome and it contracts, allowing the second limit card 505 to move upward along the guide rod 504. Then, first put one of the interceptor rods 1 of the railing on the outside of the first limit card 502, and then release the restriction of the second limit card 505. The second limit card 505 is driven by the spring 506 to engage with the top of the interceptor rod 1, thus completing the connection. Subsequently, the railing will be wound around the outside of the winding drum 501, without taking up too much volume, making it easy to transport.

[0030] like Figure 1 and Figure 2As shown, a support component 4 is installed inside the interceptor bar 1. The support component 4 includes a mounting hole 401 opened in the middle of the interceptor bar 1. A support rod 402 is slidably inserted into the mounting hole 401. A support plate 404 is fixedly connected to one end of the bottom of the support rod 402.

[0031] The support rod 402 has a through groove on its top outer wall, and a handle 403 is hinged to the inner wall of the through groove. The width of the handle 403 is smaller than the width of the through groove, which makes it easier to drive the support rod 402, but does not affect the assembly and disassembly of the support rod 402.

[0032] By rotating the support rod 402 through the handle 403, the support rod 402 causes the support plate 404 to rotate 90 degrees. With the support of the support plate 404, the railing will not tip over. When not in use, flip the support plate 404 to make it parallel to the barrier bar 1, and the railing can be laid flat for retraction.

[0033] like Figure 1 and Figure 2 As shown, several equidistant casters 2 are installed on the bottom outer wall of the winding drum 501, making the movement of the winding drum 501 more convenient.

[0034] like Figure 2 As shown, a vertically arranged through hole 405 is provided at both ends of the support plate 404. The pin can be inserted through the through hole 405 to connect the support plate 404 to the ground.

[0035] This utility model provides a temporary edge protection railing, the specific working principle of which is as follows:

[0036] When the device is in operation, pulling the railing blocks the construction area from the outside. Then, the handle 403 drives the support rod 402 to rotate, causing the support rod 402 to rotate the support plate 404 90 degrees. Supported by the support plate 404, the railing will not tip over. When not in use, flip the support plate 404 to make it parallel to the intercepting bar 1, and the railing can be laid flat for retraction. If a longer intercepting area is required, a new intercepting bar 1 is inserted into the assembly. Then, the top of the two intercepting bars 1 are connected using the connecting pin 301. The screw 303 is then rotated by the knob, extending outwards towards the screw sleeve 302. The connecting pin 301 at the bottom connects the bottom of the two guardrail bars 1, ensuring that the two guardrail bars 1 will not detach while also allowing them to be folded, providing conditions for subsequent winding work. When not in use, grasp the second limit card 505 and pull it upward. The stress of the spring 506 is overcome and it contracts, allowing the second limit card 505 to move upward along the guide rod 504. Then, first, put one of the guardrail bars 1 on the outside of the first limit card 502, and then release the restriction of the second limit card 505. The second limit card 505 is driven by the spring 506 to engage with the top of the guardrail bar 1, thus completing the connection work. Subsequently, the guardrail will be wound around the outside of the winding drum 501, without taking up too much volume, making it easy to transport.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
