Description

Technical Field

[0001] The present invention relates to the technical field of construction fences, and in particular to a construction fence and a working platform formed by the fence. Background Art

[0002] Fences refer to industrial guardrails. Guardrails are mainly used for the protection and preservation of personal safety and equipment facilities. In the process of ship maintenance, fences are often needed to isolate the work area from the outside world, and usually involve high-altitude operations. The so-called high-altitude operations refer to operations performed by people at a height based on a certain position. When working in a ship, if the operation is performed on a shelf above 2m, it is considered high-altitude operation. In order to prevent workers from falling during high-altitude operations, fences are generally installed on the aerial work platform for protection.

[0003] Prior art includes an invention patent with publication number CN118241926A, which discloses "a construction fence, relating to the technical field of building protection equipment, specifically a construction fence, comprising a support column, a support seat is fixedly installed at the bottom of the support column, a through groove is opened inside the support column, a first lead screw is rotatably connected inside the through groove, a first lifting seat is transmission-connected to the outer side of the first lead screw, a first lifting limit seat is fixedly installed on the outer side of the first lifting seat, and the outer side of the first lifting limit seat is slidably connected to the inside of the through groove".

[0004] The inventor found in his daily work that even if the current fence is not fixed with bolts, it is still fixed in the horizontal direction (that is, it cannot move in the horizontal direction). When repairing ships at high altitudes, the fence plays a role in preventing people or objects from falling. Since the fence is fixed in the horizontal direction, it is easy for the fence to bend or break at the interface when it is subjected to great compression, causing the risk of falling. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a construction fence and a working platform formed by the fence.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: a construction fence, including a blocking part, the blocking part includes:

[0007] A vertical blocking mechanism, wherein a plurality of vertical blocking mechanisms are provided, and the plurality of vertical blocking mechanisms are vertically arranged to block the horizontal direction;

[0008] It also includes: a supporting part and a pedal part, wherein the pedal part is provided for people to step on to play a supporting role, and the vertical blocking mechanism and the pedal part rotate, wherein the vertical blocking mechanism pulls the supporting part when tilting outward, and the supporting part pushes up part of the pedal part to make the edge of the pedal part tilt upward.

[0009] The effects achieved by the above-mentioned components are as follows: multiple vertical blocking mechanisms are evenly arranged to form the main part of the fence, and the main part of the fence plays a role in enclosing and blocking the construction site. When the vertical blocking mechanism is squeezed outward, the vertical blocking mechanism can rotate and tilt to reduce the deformation or even breakage caused by excessive force at the connection of the vertical blocking mechanism. When the vertical interception mechanism is tilted by force, the lifting part is pulled, wherein the lifting part pushes the stepping part at the vertical interception mechanism upward, and then the stepping part is tilted upward near the position of the vertical interception mechanism to form an inclined plane. The setting of the inclined plane can alleviate the subsequent continuous squeezing of the vertical blocking mechanism to reduce the risk of falling caused by excessive squeezing of the fence body.

[0010] Preferably, the vertical blocking mechanism comprises:

[0011] A railing, wherein a hydraulic chamber is provided inside the railing, and a first piston is slidably connected inside the hydraulic chamber;

[0012] A rectangular groove, the rectangular groove is opened on the side of the railing, the inner wall of the rectangular groove is provided with a slide groove along the central axis of the railing, wherein a rack is slidably connected inside the slide groove, and the rack is fixed to the first piston;

[0013] The gear is rotatably mounted inside a rectangular groove, the gear is meshed with a rack, a movable intercepting rod is fixedly connected to the surface of the gear, and the movable intercepting rod is arranged in the rectangular groove.

[0014] Preferably, the pedal part includes a hydraulic mechanism, and the hydraulic mechanism includes:

[0015] A rectangular long tube, a mounting seat is fixedly mounted on the side of the rectangular long tube, and the railing is rotatably connected to the mounting seat;

[0016] A second piston, wherein the second piston slides horizontally in the rectangular cylinder to guide the hydraulic oil inside the rectangular cylinder into the hydraulic cavity through a hose;

[0017] A driving arm, wherein one end of the driving arm is movably connected to the railing, and the other end is connected to the second piston; a sealing head, wherein the sealing head is fixed to the port of the rectangular long cylinder to seal and fix the port.

[0018] The effect achieved by the above components is: when the vertical blocking mechanism is pushed by external force, the railing rotates on the mounting seat, the railing tilts outward, and the lower part of the mounting seat drives the driving arm inward to squeeze the second piston, and the second piston squeezes the hydraulic oil in the rectangular cylinder, and the hydraulic oil enters the hydraulic chamber through the hose, and the first piston in the hydraulic chamber drives the rack to extend outward, and the gear meshing with the rack rotates to make the movable intercepting rod rotate out of the rectangular groove, and then in the process of the railing tilting outward, its upper part rotates inward to pull out the movable intercepting rod, and the upper part of the stacked material is pushed inward by the movable intercepting rod, so that the center of gravity of the stacked material moves away from the railing, and cooperates with the upward-pushing pedal to make the material tend to move away from the railing position, thereby reducing the long-term squeezing of the railing and causing the material to fall.

[0019] Preferably, the treading portion further comprises:

[0020] Pedal: The pedal can be stepped on and bear weight, the bottom end of the pedal is fixed by a column and a rectangular long tube, and multiple pedals are evenly arranged;

[0021] A supporting beam, which supports and fixes the bottom of the pedal; a spacing mechanism, wherein the spacing mechanism is located between two adjacent pedals, and a port of the spacing mechanism can be lifted up by the lifting part and bent upward.

[0022] Preferably, the spacing mechanism comprises:

[0023] A partition board, wherein the bottom end of the partition board is fixed by a column and a supporting beam, the end of the partition board is bent upward, and a reinforcing rib is provided at the bottom of the partition board, and the reinforcing rib strengthens the partition board and the pedal;

[0024] A water guide groove, wherein a plurality of water guide grooves are opened downward from the edge of the partition plate, and the water guide grooves can discharge the water above the partition plate downward;

[0025] A bending member, wherein the bending member is arranged on the upper part of the partition plate for the partition plate to bend upward; the bending member includes a transverse groove opened on the upper end of the partition plate, and a square hole is opened downwardly through the surface of the partition plate relative to the position of the transverse groove, and a tension spring is fixed between the railing and the column. Since the transverse groove is opened on the surface of the partition plate, the setting of the transverse groove reduces the thickness of the partition plate at this point, and the partition plate is prone to bend at the transverse groove when subjected to external force, wherein the square hole can further reduce the strength of the partition plate to facilitate bending, and at the same time can increase the friction of the partition plate, and can also improve the drainage effect of the partition plate.

[0026] The effects achieved by the above components are as follows: the pedals serve as a load-bearing basis, wherein the partitions between the pedals, on the one hand, form a height difference with the pedals to increase the friction of the pedals, and on the other hand, the partitions block the gaps between the pedals to prevent materials from falling through the gaps between the pedals; on the other hand, the pedals close to the railings can be bent upward to push out the pedals to form an inclined plane to bear the load in place of the pedals (due to the inclined plane bearing the load, people or objects on the inclined plane have a tendency to slide down the inclined plane, that is, a tendency to move away from the guardrail body) to bring people or objects closer to the guardrail body to reduce the risk of falling; finally, on the other hand, the port of the pedal extending out of the railing bends upward to support and store objects that fall from the edge of the railing.

[0027] Preferably, the supporting portion comprises:

[0028] Static beams, where the static beams are fixed horizontally to the sides of the columns;

[0029] A lifting wedge block, wherein the lifting wedge block slides upward at an angle at the upper end of the static beam to lift the spacer plate, and the lifting wedge block is pulled by a rope when the railing rotates; a wire hole, wherein the wire hole is opened on the column for the rope to pass through, an inclined groove is opened on the edge of the static beam, and an inclined surface is provided at the bottom end of the lifting wedge block, and the lifting wedge block slides on the inclined groove through the inclined surface, and the port of the lifting wedge block is fixedly connected to a connecting cross plate, one end of the connecting cross plate is fixedly connected to a reset spring, and the other end of the reset spring is fixed to the column.

[0030] The effect achieved by the above components is: one end of the rope is tied to the surface of the pull rod above the mounting seat, and the other end of the rope is passed through the wire hole and fixed on the connecting cross plate. When the railing is pressed and tilted outward, the rope pulls the lifting wedge, and the lifting wedge slides obliquely on the static beam to lift the partition plate upward. When the railing is not subject to external force, the elastic force of the reset spring pulls the lifting wedge to reset, and the elastic force of the reset spring can also pull the pull rod to reset.

[0031] Preferably, it further comprises a clamping beam, wherein the clamping beam clamps a plurality of railings.

[0032] Preferably, a protective mechanism is provided on the surface of the railing, wherein the protective mechanism comprises:

[0033] A rubber sleeve, which is sleeved on the surface of the railing at the position of the rectangular groove;

[0034] A tightening ring, wherein the tightening ring is sleeved on the surfaces of the two ends of the rubber sleeve to tie it to the surface of the railing;

[0035] A wheel groove is provided at the end of the movable intercepting rod, wherein a roller is rotatably connected inside the wheel groove.

[0036] The effects achieved by the above components are: the rubber sleeve is put on the surface of the railing through the tightening ring, and the rectangular groove is wrapped with the rubber sleeve to prevent outside rain or dust from entering the rectangular groove; when the movable intercepting rod rotates and extends out of the rectangular groove, the rubber sleeve is squeezed and deformed, and the roller at the end of the movable intercepting rod prevents direct contact between the movable intercepting rod and the rubber sleeve from causing damage to the rubber sleeve when squeezing the rubber sleeve.

[0037] Preferably, the protection mechanism further comprises:

[0038] A reinforcing sleeve, the reinforcing sleeve being sleeved on the surface of the railing at the position of the rectangular groove;

[0039] A reinforcing rib is provided, wherein the reinforcing rib is fixed on the surface of the railing relative to the hydraulic chamber.

[0040] Preferably, a working platform formed by a construction fence is composed of the construction fence.

[0041] Compared with the prior art, the advantages and positive effects of the present invention are:

[0042] 1. In the present invention, when the vertical blocking mechanism is squeezed outward, the vertical interception mechanism can rotate and tilt to reduce the deformation or even breakage caused by excessive force at the connection of the vertical interception mechanism. Although the vertical interception mechanism can rotate due to the presence of the first piston, the movement distance of the first piston limits the rotation range of the vertical interception mechanism, thereby preventing excessive rotation from causing people or objects to quickly rush out of the vertical interception mechanism.

[0043] 2. In the present invention, when the vertical intercepting mechanism is tilted by force, the lifting part is pulled, wherein the lifting part pushes up the treading part at the vertical intercepting mechanism, thereby causing the treading part to tilt upward near the vertical intercepting mechanism to form an inclined plane. The setting of the inclined plane can alleviate the subsequent continuous squeezing of the vertical blocking mechanism to reduce the risk of falling caused by excessive squeezing of the fence body.

[0044] 3. In the present invention, the upper part of the stacked materials is pushed inward by the movable intercepting rod, so that the center of gravity of the stacked materials moves away from the railing. The upwardly pushed pedal part makes the materials tend to move away from the railing, thereby reducing the long-term squeezing of the railing and causing the materials to fall. The movable intercepting rod rotates inward to push the upper limbs of the person to remind the person that too much thrust has been applied to the vertical intercepting mechanism, and reminds the person to stay away from the vertical intercepting mechanism.

[0045] 4. In the present invention, the partition plates between the pedals, on the one hand, form a height difference with the pedals to increase the friction of the pedals, and on the other hand, the partition plates block the gaps between the pedals to prevent materials from falling through the gaps between the pedals. On the other hand, the pedals close to the railings can be bent upward to push out the pedals to form an inclined plane to bear the load instead of the pedals (because the inclined plane bears the load, people or objects on the inclined plane have a tendency to slide down the inclined plane, that is, a tendency to move away from the guardrail body) to bring people or objects closer to the guardrail body to reduce the risk of falling. Finally, on the other hand, the end of the pedal extending out of the railing is bent upward to support and store objects that fall from the edge of the railing.

[0046] 5. In the present invention, the rope pulls the lifting wedge, and the lifting wedge slides obliquely on the static beam to lift the partition plate upward. When the handrail is not subjected to external force, the elastic force of the reset spring pulls the lifting wedge to reset. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0060] Embodiment 1, as Figures 1 to 3As shown, this embodiment discloses a construction fence, including a blocking part 1, which includes: a vertical blocking mechanism 11, wherein a plurality of vertical blocking mechanisms 11 are provided, and the plurality of vertical blocking mechanisms 11 are vertically arranged to block the horizontal direction; and further includes: a supporting part 5 and a treading part 4, wherein the treading part 4 is provided for people to step on to play a supporting role, and the vertical blocking mechanism 11 and the treading part 4 rotate, wherein the vertical blocking mechanism 11 pulls the supporting part 5 when tilting outward, and the supporting part 5 pushes up a part of the treading part 4 to make the edge of the treading part 4 tilt upward, and the plurality of vertical blocking mechanisms 11 are evenly arranged to form the main part of the fence, and the fence The main part plays the role of enclosing and blocking the construction site. When the vertical blocking mechanism 11 is squeezed outward, the vertical blocking mechanism can rotate and tilt to reduce the deformation or even breakage caused by excessive force at the connection of the vertical blocking mechanism. When the vertical blocking mechanism is tilted by force, the lifting part 5 is pulled, wherein the lifting part 5 pushes up the pedal part 4 at the vertical interception mechanism, and then the pedal part 4 is tilted upward near the vertical interception mechanism to form an inclined plane. The setting of the inclined plane can alleviate the subsequent continuous squeezing of the vertical blocking mechanism 11 to reduce the risk of falling caused by excessive squeezing of the fence body.

[0061] like Figures 4 to 6As shown, the vertical blocking mechanism 11 includes: a railing 111, wherein a hydraulic chamber 112 is arranged inside the railing 111, and a first piston 113 is slidably connected inside the hydraulic chamber 112; a rectangular groove 115, wherein the rectangular groove 115 is opened on the side of the railing 111, and a slide groove 116 is opened on the inner wall of the rectangular groove 115 along the central axis of the railing 111, wherein a rack 114 is slidably connected inside the slide groove 116, and the rack 114 and the first piston 113 are fixed; a gear 117, wherein the gear 117 is rotatably installed inside the rectangular groove 115, the gear 117 is meshed with the rack 114, and a movable intercepting rod 118 is fixedly connected to the surface of the gear 117, and the movable intercepting rod 118 is arranged in the rectangular groove 115, and the pedal part 4 includes a hydraulic mechanism 41, and the hydraulic mechanism 41 includes: a rectangular long cylinder 411, and a mounting seat 13 is fixedly installed on the side of the rectangular long cylinder 411, and the railing 111 and the mounting seat 13 are rotatably connected; a second piston 412, wherein the second piston 412 slides horizontally in the rectangular long cylinder 411 to introduce the hydraulic oil inside the rectangular long cylinder 411 into the hydraulic chamber 112 through the hose 413; a driving arm 414, wherein one end of the driving arm 414 is movably connected to the railing 111, and the other end is connected to the second piston 412; a head 415, and the head 415 is fixed to the port of the rectangular long cylinder 411 to seal and fix its port. When the vertical blocking mechanism 11 is pushed by external force, the railing 111 rotates on the mounting seat 13, and the railing 111 tilts outward. The lower part of the mounting seat 13 drives the driving arm 414 inward to squeeze the second piston 412. The second piston 412 squeezes the hydraulic oil in the rectangular cylinder 411. The hydraulic oil enters the hydraulic chamber 112 through the hose 413. The first piston 113 in the hydraulic chamber 112 drives the rack 114 to extend outward, and the gear 117 meshing with the rack 114 rotates, thereby causing the movable intercepting rod 118 to rotate out of the rectangular groove 115. Then, in the process of the railing 111 tilting outward, its upper part rotates inward to pull out the movable intercepting rod 118, and the upper part of the stacked material is pushed inward by the movable intercepting rod 118, so that the center of gravity of the stacked material moves away from the railing 111. In conjunction with the upward-pushing treading part 4, the material has a tendency to move away from the railing 111, thereby reducing the long-term squeezing of the railing 111 and causing the material to fall.

[0062] like Figures 7 to 12As shown, the pedal portion 4 also includes: a pedal 43: wherein the pedal 43 can be stepped on and bear weight, the bottom end of the pedal 43 is fixed by a column and a rectangular long tube 411, and multiple pedals 43 are evenly arranged; a supporting beam 42, which supports and fixes the bottom of the pedal 43; a spacer mechanism 44, wherein the spacer mechanism 44 is located between two adjacent pedals 43, and the end of the spacer mechanism 44 can be lifted up by the lifting portion 5 and bent upward.The partition mechanism 44 includes: a partition plate 441, wherein the bottom end of the partition plate 441 is fixed by a column and a supporting beam 42, the end of the partition plate 441 is bent upward, and a reinforcing rib is provided at the bottom of the partition plate 441, and the reinforcing rib strengthens the strength of the partition plate 441 and the pedal 43; a water guide groove 442, wherein a plurality of water guide grooves 442 are opened downward from the edge of the partition plate 441, and the water guide groove 442 can discharge the water above the partition plate 441 downward; a bending member 443, wherein the bending member 443 is arranged at the upper part of the partition plate 441 for the partition plate 441 to bend upward; the bending member 443 includes a transverse groove 4431 opened at the upper end of the partition plate 441, and the partition plate A square hole 4432 is provided on the surface of 441 downwardly relative to the position of the transverse groove 4431, and a tension spring 3 is fixed between the railing 111 and the column. Since the transverse groove 4431 is provided on the surface of the partition plate 441, the setting of the transverse groove 4431 reduces the thickness of the partition plate 441 at this location, and the partition plate 441 is easily bent at the transverse groove 4431 when subjected to external force, wherein the square hole 4432 can further reduce the strength of the partition plate 441 to facilitate bending, and at the same time can also increase the friction of the partition plate 441, and can also improve the drainage effect of the partition plate 441, and the pedal 43 serves as a load-bearing foundation, wherein the partition plate 441 located between the pedals 43 is on the one hand and on the other hand, On the other hand, the spacer plate 441 blocks the gap between the pedals 43 to prevent materials from falling through the gap between the pedals 43. On the other hand, the position of the pedal 43 close to the railing 111 can be bent upward to push out the pedal 43 to form an inclined plane to bear the load on the replacement pedal 43 (because the inclined plane bears the load, people or objects on the inclined plane have a tendency to slide down the inclined plane, that is, a tendency to move away from the guardrail body) to bring people or objects close to the guardrail body to reduce the risk of falling. Finally, on the other hand, the port of the pedal 43 extending out of the railing 111 is bent upward to support and store objects that fall from the edge of the railing 111, thereby lifting the guardrail body. Part 5 includes: a static beam 51, wherein the static beam 51 is horizontally fixed on the side of the column; a lifting wedge 53, wherein the lifting wedge 53 slides obliquely upward at the upper end of the static beam 51 to lift the spacer 441, and the lifting wedge 53 is pulled by a rope when the railing 111 rotates; a wire hole 56, wherein the wire hole 56 is opened on the column for the rope to pass through, an inclined groove 52 is opened on the edge of the static beam 51, and an inclined surface is provided at the bottom end of the lifting wedge 53, and the lifting wedge 53 slides on the inclined groove 52 through the inclined surface, and the port of the lifting wedge 53 is fixedly connected to a connecting cross plate 54, and one end of the connecting cross plate 54 is fixedly connected to a reset spring 55, wherein the other end of the reset spring 55 is fixed to the column.One end of the rope is tied to the surface of the pull rod above the mounting seat 13, and the other end of the rope is passed through the wire hole 56 and fixed on the connecting cross plate 54. When the railing 111 is pressed and tilted outward, the rope pulls the lifting wedge 53, and the lifting wedge 53 slides obliquely on the static beam 51 to lift the partition plate 441 upward. When the railing 111 is not subject to external force, the elastic force of the reset spring 55 pulls the lifting wedge 53 to reset, and the elastic force of the reset spring 55 can also pull the pull rod to reset, and also includes a clamping beam 2, wherein the clamping beam 2 clamps multiple railings 111. A protective mechanism 12 is provided on the surface of the railing 111, wherein the protective mechanism 12 includes: a rubber sleeve 122, which is sleeved on the surface of the railing 111 at the position of the rectangular groove 115; a tightening ring 123, wherein the tightening ring 123 is sleeved on the two end surfaces of the rubber sleeve 122 to bind it to the surface of the railing 111; a wheel groove is opened at the end of the movable intercepting rod 118, wherein a roller 119 is rotatably connected inside the wheel groove. The rubber sleeve 122 is sleeved on the surface of the railing 111 through the tightening ring 123, and the rectangular groove 115 is wrapped by the rubber sleeve 122 to prevent external rain or dust from entering the rectangular groove 115. When the movable intercepting rod 118 rotates and extends out of the rectangular groove 115, the rubber sleeve 122 is squeezed and deformed. The roller 119 at the end of the movable intercepting rod 118 prevents direct contact between the movable intercepting rod 118 and the rubber sleeve 122 when squeezing the rubber sleeve 122, thereby preventing the rubber sleeve 122 from being damaged. The protective mechanism 12 also includes: a reinforcing sleeve 121, which is sleeved on the surface of the railing 111 at the position of the rectangular groove 115; and reinforcing ribs, wherein the reinforcing ribs are fixed on the surface of the railing 111 relative to the hydraulic chamber 112.

[0063] A working platform formed by a construction fence is composed of a construction fence. The technical solution of this case can be placed above a scaffold and fixed to the scaffold by welding or bolt clamps.

[0064] Working principle: multiple vertical blocking mechanisms 11 are evenly arranged to form a fence main body. The fence main body serves to block the ship maintenance scaffolding to prevent people or objects on the scaffolding from falling. When people or objects on the scaffolding are close to the fence main body, they are easy to squeeze the vertical blocking mechanism 11. When squeezing the vertical blocking mechanism 11 outward, the vertical blocking mechanism can rotate and tilt to reduce the deformation or even breakage caused by excessive force at the connection of the vertical blocking mechanism. When the vertical blocking mechanism is tilted by force, the lifting part 5 is pulled, wherein the lifting part 5 pushes the treading part 4 at the vertical interception mechanism upward, and then the position of the treading part 4 close to the vertical interception mechanism is tilted upward to form an inclined plane. The setting of the inclined plane can alleviate the subsequent continuous squeezing of the vertical blocking mechanism 11 to reduce the risk of falling caused by excessive squeezing of the fence main body (because there are only two situations of squeezing the vertical interception mechanism: objects or people: when the object squeezes the vertical interception mechanism, due to the existence of the inclined plane, the object always has a tendency to slide along the inclined plane to reduce the squeezing force on the vertical interception mechanism;When a person squeezes the vertical interception mechanism, due to the existence of the inclined surface, the person needs to overcome the sliding downward along the inclined surface, and thus needs to be reminded that the vertical interception mechanism has been squeezed, thereby preventing the person from falling on the vertical interception mechanism). When the vertical blocking mechanism 11 is pushed by an external force, the railing 111 rotates on the mounting seat 13, and the railing 111 tilts outward and the lower part of the mounting seat 13 drives the driving arm 414 inward to squeeze the second piston 412. The second piston 412 squeezes the hydraulic oil in the rectangular cylinder 411, and the hydraulic oil enters the hydraulic chamber 112 through the hose 413. The first piston 113 in the hydraulic chamber 112 drives the rack 114 to extend outward, and the gear 117 meshing with the rack 114 rotates to make the active The movable intercepting rod 118 rotates out of the rectangular groove 115, and then in the process of the guardrail 111 tilting outward, its upper part rotates inwardly out of the movable intercepting rod 118, and the upper part of the stacked materials is pushed inward by the movable intercepting rod 118, so that the center of gravity of the stacked materials moves away from the guardrail 111, and the upwardly lifted pedal part 4 makes the materials have a tendency to move away from the guardrail 111, thereby reducing the long-term squeezing of the guardrail 111 and causing the materials to fall. The pedals 43 serve as a load-bearing basis, wherein the spacer plates 441 located between the pedals 43 form a height difference with the pedals 43 on the one hand to increase the friction of the pedals 43, and on the other hand, the spacer plates 441 block the gaps between the pedals 43 to prevent the materials from falling between the pedals 43 The position of the pedal 43 near the railing 111 can be bent upward to push out the pedal 43 to form an inclined plane to bear the load instead of the pedal 43 (because the inclined plane bears the load, the person or object on the inclined plane has a tendency to slide down the inclined plane, that is, a tendency to move away from the guardrail body) to bring the person or object close to the guardrail body to reduce the risk of falling. Finally, on the other hand, the end of the pedal 43 extending out of the railing 111 is bent upward to support and store objects that fall from the edge of the railing 111. One end of the rope is tied to the surface of the pull rod above the mounting seat 13, and the other end of the rope is fixed to the connecting cross plate 54 through the wire hole 56. When the railing 111 is pressed and tilted outward, the rope pulls the wedge block 53 to lift it up. The lifting wedge 53 slides obliquely on the static beam 51 to lift the spacer plate 441 upward. When the railing 111 is not subjected to external force, the elastic force of the reset spring 55 pulls the lifting wedge 53 to reset. The elastic force of the reset spring 55 can also pull the pull rod to reset. The rubber sleeve 122 is sleeved on the surface of the railing 111 through the tightening ring 123. The rectangular groove 115 is wrapped by the rubber sleeve 122 to prevent external rain or dust from entering the rectangular groove 115. When the movable intercepting rod 118 rotates and extends out of the rectangular groove 115, the rubber sleeve 122 is squeezed and deformed. When the roller 119 at the end of the movable intercepting rod 118 squeezes the rubber sleeve 122, it prevents the movable intercepting rod 118 and the rubber sleeve 122 from directly contacting each other and causing damage to the rubber sleeve 122. ;
