Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a safety fence suitable for uneven ground. Background Technology
[0002] A safety fence is a type of fencing used to isolate or protect an area. It consists of two support poles and a mesh fence, which is secured between the two support poles using bolts and clips. Its main function is to prevent people or objects from accidentally entering a dangerous area or to prevent falls, thereby ensuring safety, protecting personnel, and preventing accidents.
[0003] Different ground conditions may occur during construction, and uneven ground is the most common. However, most safety fences nowadays have a rigid connection structure, and their bottom is supported by flat plates. These types of safety fences are only suitable for use on flat ground. When they need to be used on uneven ground, the bottom plates of the safety fence cannot stand stably on the slope, which can easily lead to the collapse of the safety fence.
[0004] Based on this, this utility model designs a safety fence suitable for uneven ground to solve the above problems. Utility Model Content
[0005] In view of the problem that safety fences are unstable when standing on uneven ground, leading to fence collapse, as described above or in the prior art, this utility model is proposed.

[0010] As a preferred embodiment of the present invention for a safety fence applicable to uneven ground, wherein: a stabilizing rod is fixedly installed on the inner wall of each of the two inner grooves on opposite sides, two L-shaped locking blocks are respectively sleeved on the outer ends of the two stabilizing rods, and two clamping springs are respectively sleeved on the outer ends of the two stabilizing rods.
[0011] As a preferred embodiment of the present invention for a safety fence applicable to uneven ground, wherein: a rear groove is provided on the inner wall of the rear side of the pole groove, and a push-out spring is fixedly provided between the rear groove and the push plate.
[0012] As a preferred embodiment of the present invention for a safety fence applicable to uneven ground, wherein: the push rod is slidably sleeved on the inner wall of the shaft block, the four inclined blocks are respectively slidably disposed on the inner walls of the four moving grooves, and the four inclined blocks are respectively in contact with the inclined surfaces of the four pressure plates.
[0013] As a preferred embodiment of the present invention for a safety fence applicable to uneven ground, wherein: a movable block is fixedly provided on the rear end face of the movable foot, a fixed block is fixedly provided on the front end face of the fixed foot, the movable block is slidably disposed on the inner wall of the fixed block, and is fixed by bolts.
[0014] As a preferred embodiment of the present invention for a safety fence applicable to uneven ground, wherein: the outer plate is set in the outer groove position, the shaft block is rotatably set in the inner wall of the shaft groove, the end of the push rod is set in the inner wall of the rod groove, the two L-shaped locking blocks are clamped in the inner wall of the limiting ring groove, and the outer plate is set at the upper end of the fixed foot.
[0015] The beneficial effects of this utility model on a safety fence suitable for uneven ground are as follows: This utility model adjusts the angle of the outer plate on the inner wall of the outer groove by rotating the outer plate, which in turn causes the axle block to rotate within the groove. This, in turn, drives the support foot mechanism to adjust the angle. After adjusting to the appropriate angle, pressing the push rod causes the end of the push rod to slide into the inner wall of the rod groove. The locking spring pushes the L-shaped locking block into the inner wall of the limiting groove, thus restricting the position of the push rod. The push rod sliding backward causes the inclined block to press against the pressure plate, thereby pressing the pressure plate against the inner wall of the axle groove and fixing the axle block. The fixed axle block determines the position of the support foot mechanism. The flexibly adjustable support foot mechanism allows the fence to adapt to uneven ground, thus effectively preventing the fence from collapsing. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] Example, refer to Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides a safety fence suitable for uneven ground, which can achieve the effect of making the fence stand stably on uneven ground.
[0030] Specifically, the mechanism includes a railing 1 and its supporting rods 2 on both sides, a lower rod mechanism 3, a lower rod body 301 and a push plate 309. The lower rod body 301 has an outer groove 302 at the lower front end, a shaft groove 303 on the rear inner wall of the outer groove 302, a rod groove 304 on the rear inner wall of the shaft groove 303, and inner grooves 305 on both sides of the rod groove 304. L-shaped locking blocks 306 are provided on the inner walls of the two inner grooves 305. Loosening blocks 312 are fixedly provided on the rear end faces of the two L-shaped locking blocks 306, and locking springs 307 are fixedly provided on the opposite end faces of the two L-shaped locking blocks 306.
[0031] The locking mechanism 4 includes an outer plate 401 and a push rod 403. A shaft block 402 is fixedly installed at the rear end of the outer plate 401. Four movable slots 406 are equidistantly opened on the outside of the shaft block 402. A pressure plate 404 is slidably installed on the inner wall of each of the four movable slots 406. Four inclined blocks 407 are fixedly installed equidistantly on the outside of the push rod 403. A limit ring groove 405 is opened on the rear side of the outside of the push rod 403.
[0032] The support foot mechanism 5 includes a fixed foot 501 and a movable foot 504, and an arc block 502 is fixedly provided on the upper end surface of the fixed foot 501.
[0033] Furthermore, rotating the outer plate 401 inside the outer groove 302 causes the shaft block 402 connected to the outer plate 401 to rotate inside the shaft groove 303. By pressing the push rod 403, the tail of the push rod 403 will enter the rod groove 304. When the push rod 403 enters the rod groove 304, it will first press the L-shaped locking block 306, causing the L-shaped locking block 306 to retract into the inner groove 305. After the push rod 403 is pressed into place, the clamping spring 307 pushes the L-shaped locking block 306 into the limiting ring groove 405. At this time, the L-shaped locking block 306 will pull the push rod 403, allowing the push rod 403 to remain in its original position. In this position, the inclined block 407 on the surface of the push rod 403 presses against the pressure plate 404 through the inclined surface. This inclined surface pressing will cause the pressure plate 404 to be pressed tightly inside the shaft groove 303. Friction will fix the axle block 402, thereby fixing the position of the support foot mechanism 5. The support foot mechanism 5 consists of a fixed foot 501 and a movable foot 504. The movable foot 504 can move up and down, thereby changing the height difference between the movable foot 504 and the fixed foot 501, so as to adapt to different ground conditions. Moreover, an arc block 502 is provided on the fixed foot 501. The arc block 502 fits with the rounded corner of the lower rod body 301, so that the arc block 502 can support the lower rod body 301 and prevent the pressure of the lower rod body 301 from being concentrated on the axle block 402. The support foot mechanism 5 is placed on the ground and supports the lower rod mechanism 3 through the locking mechanism 4. The lower rod mechanism 3 supports the support rod 2 above it. The railing 1 is placed between the two support rods 2 to form the whole fence.
[0034] Specifically, the lower rod mechanism 3 is located at the lower end of the support rod 2, the locking mechanism 4 is located at the lower front side of the lower rod mechanism 3, and the support foot mechanism 5 is located at the lower end of the locking mechanism 4.
[0035] Furthermore, each of the two support rods 2 is equipped with a lower rod mechanism 3. The two lower rod mechanisms 3 have the same structure. The two support rods 2 are fixed to the fence by bolts and buckles. Moreover, the angle of the support foot mechanism 5 can be adjusted and controlled by the self-locking structure of the locking mechanism 4.
[0036] Specifically, a stabilizing rod 308 is fixedly installed on the inner wall of each of the two inner grooves 305 on opposite sides, two L-shaped locking blocks 306 are respectively sleeved on the outer ends of the two stabilizing rods 308, and two locking springs 307 are respectively sleeved on the outer ends of the two stabilizing rods 308.
[0037] Furthermore, the stability of the L-shaped locking block 306 can be enhanced by the stabilizing rod 308 set inside the inner groove 305, effectively preventing the L-shaped locking block 306 from swinging when sliding inside the inner groove 305. Moreover, the clamping spring 307 sleeved on the stabilizing rod 308 can push the L-shaped locking block 306, allowing the L-shaped locking block 306 to be locked into the limiting ring groove 405 to tighten and fix the push rod 403, thereby forming a self-locking mechanism for the push rod 403.
[0038] Specifically, a rear groove 310 is provided on the rear inner wall of the rod groove 304, and an ejector spring 311 is fixedly provided between the rear groove 310 and the push plate 309.
[0039] Furthermore, when the angle of the support foot mechanism 5 needs to be adjusted, the L-shaped locking block 306 is released, and the spring 311 pushes the push rod 403 to pop out, thereby canceling the self-locking structure.
[0040] Specifically, the push rod 403 is slidably sleeved on the inner wall of the shaft block 402, and the four inclined blocks 407 are respectively slidably disposed on the inner walls of the four moving grooves 406, and the four inclined blocks 407 respectively contact the inclined surfaces of the four pressure plates 404.
[0041] Furthermore, the push rod 403 slides inside the shaft block 402, while the inclined block 407 on the push rod 403 slides inside the moving groove 406. The restriction of the inclined block 407 can prevent the push rod 403 from sliding out of the shaft block 402. When the push rod 403 is pressed backward, the inclined surface above it pushes against the pressure plate 404, causing the pressure plate 404 to press into the shaft groove 303, thereby fixing the shaft block 402.
[0042] Specifically, a movable block 505 is fixedly provided on the rear end face of the movable foot 504, and a fixed block 503 is fixedly provided on the front end face of the fixed foot 501. The movable block 505 is slidably disposed on the inner wall of the fixed block 503 and is fixed by bolts.
[0043] Furthermore, the support foot mechanism 5 consists of a movable foot 504 and a fixed foot 501. The movable block 505 on the movable foot 504 slides inside the fixed block 503 on the fixed foot 501, thereby adjusting the height of the movable foot 504. After adjustment, the adjustable foot is fixed by bolts, so that the fixed foot 501 and the movable foot 504 form a height difference, which can adapt to the placement on ground with different inclinations.
[0044] Specifically, the outer plate 401 is located at the outer groove 302, the shaft block 402 is rotatably mounted on the inner wall of the shaft groove 303, the tail end of the push rod 403 is mounted on the inner wall of the rod groove 304, the two L-shaped locking blocks 306 are clamped on the inner wall of the limiting ring groove 405, and the outer plate 401 is mounted on the upper end of the fixing foot 501.
[0045] Furthermore, the outer plate 401 is positioned in the outer groove 302, and the outer plate 401 is supported by the shaft block 402 located inside the shaft groove 303. The pressed rod 403 enters the rod groove 304 and is clamped by the L-shaped locking block 306 in the limiting ring groove 405 to form a fixed position.
[0046] In use, the guardrail 1 is fixed between two support rods 2 with bolts. A lower rod mechanism 3 is provided below the support rods 2 for support. The lower rod body 301 of the lower rod mechanism 3 is connected to the support foot mechanism 5 through a locking mechanism 4. By pressing the button 403 in front of the outer block inside the locking mechanism 4, the pressed button 403 will move backward, allowing the tail of the button 403 to enter the rod groove 304. When the button 403 enters, it will first squeeze the L-shaped locking block 306 inside the inner groove 305, allowing the L-shaped locking block 306 to enter the inner groove 305. The L-shaped locking block 306 retracts into the inner groove 305. After the push rod 403 is pressed into place, the locking spring 307 sleeved on the outside of the stabilizing rod 308 pushes the L-shaped locking block 306 into the limiting ring groove 405 to lock the push rod 403. After the push rod 403 is pressed, it will press the pressure plate 404 through the inclined block 407, thereby causing the pressure plate 404 to slide out of the moving groove 406 and press into the inside of the shaft groove 303. Through friction, the shaft block 402 is fixed, thus fixing the outer plate 401 inside the outer groove 302. The position of the fixed foot 501 can be adjusted by adjusting the angle of the fixed foot 501 and sliding the movable foot 504, allowing the movable block 505 on the movable foot 504 to slide inside the fixed block 503 and then be fixed by bolts, thereby adjusting the height difference between the movable foot 504 and the fixed foot 501 to adapt to uneven ground. When further adjustment of the support foot mechanism 5 is needed, the loosening block 312 is slid to both sides, and the sliding loosening block 312 will pull the L-shaped locking block 306, allowing the L-shaped locking block 306 to move. When the inner groove 305 is released, the fixing of the push rod 403 is released. At this time, the ejector spring 311 inside the rear groove 310 pushes the push plate 309 to push the push rod 403, causing the push rod 403 to pop out of the inclined block 407 above it and release the pressure plate 404. This allows the shaft block 402 to rotate again inside the shaft groove 303. Moreover, there is always an arc block 502 above the fixed foot 501. The arc block 502 can fit with the rounded corner below the lower rod body 301 to form a support for the lower rod body 301.
[0047] In summary, when the support foot mechanism 5 is fixed, pressing the lever 403 causes it to move backward. The inclined block 407 on the surface of the lever 403 pushes the pressure plate 404, causing the pressure plate 404 to slide out of the moving groove 406 and press into the inside of the shaft groove 303, thereby fixing the shaft block 402. Moreover, the tail of the pressed lever 403 will enter the rod groove 304, and the L-shaped locking block 306 pushed by the locking spring 307 will lock the limiting ring groove 405, so that the inclined block 407 on the lever 403 can always press against the pressure plate 404, thereby fixing the angle of the support foot mechanism 5.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
