The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

The present application is further described below with reference to fig. 1 to 4 and examples.

The anti-falling device is applied to ladders and maintenance towers during outdoor decoration aloft work, and is exemplified by an aloft ladder shown in figure 1, a common outdoor decoration ladder comprises a ladder frame 100, wherein the ladder frame 100 comprises a straight ladder and an inclined ladder, the straight ladder is connected with the top of the inclined ladder, the bottom of the straight ladder is connected with the bottom of the inclined ladder through a bottom plate 140, and the bottom of the straight ladder and the bottom of the inclined ladder are respectively positioned at two ends of the bottom plate 140; universal wheels and directional wheels are arranged below the bottom plate 140 and used for moving the high-altitude ladder.

As shown in fig. 2 and 3, the present application discloses an outdoor anti-falling protection device for engineering decoration, which comprises ladder frames 100, pedals 110 positioned between the ladder frames 100; a press rod 200 positioned at both sides of the pedal 110; a receiving groove 120 between the ladder frame 100 and the step plate 110 for receiving the pressing bar 200; the root of the pressure lever 200 is rotatably connected to the ladder frame 100; the pedal 110 is further provided with a positioning device for keeping the pressing rod 200 upright.

An accommodating groove 120 provided with a pressure lever 200 is arranged between the pedal 110 and the ladder frame 100, the pressure lever 200 can be slidably erected on one side of the pedal 110 to hook the instep of a constructor, so that the constructor can not fall from a high place; when the compression bar 200 is not needed to fix the instep, the compression bar 200 can be rotatably accommodated between the pedal 110 and the ladder rack 100, so that the operation of a constructor is facilitated; for the setting of safety belt, this application anti-falling device can hide, can not influence or occupy when high altitude ladder is unmovable, constructor operating space.

Specifically, the pressing rod 200 includes a vertical rod 210; the root of the vertical rod 210 is rotatably connected to the ladder frame 100; the end part of the vertical rod 210 is sleeved with a cross rod 220; the cross bar 220 can be embedded into the accommodating groove 120 when the vertical bar 210 is lying down; the positioning device comprises a baffle 130 vertically arranged at one side of the pedal 110; the baffle 130 is provided with a slot 150 for accommodating the cross bar 220 after the vertical bar 210 is erected.

The vertical rod 210 is used for controlling whether the pressure rod 200 is put into use, and the horizontal rod 220 is used for being matched with the instep of a constructor to limit and fix the foot of the constructor. The rail 220 is securely inserted into the slot 150 when the rail 220 is erected, so that the rail 220 is restrained and kept stable when the rail 220 is erected.

Further, the side of the baffle 130 facing the cross bar 220 is arc-shaped. The arc shape serves as a guide for the cross bar 220 to smoothly switch between the locking groove 150 and the receiving groove 120. The baffle 130 is disposed opposite to the side of the pedal 110, and a space for accommodating the pressing rod 200 is left in the middle. Therefore, when the rotating block rotates, even if foreign matters exist in the gap, the rotating block can ensure smooth rotation.

Furthermore, the ladder rack 100 is provided with a limiting member 280 at one side of the engaging groove 150; one end of the cross rod 220 connected to the vertical rod 210 is provided with a clamping member 290 which is matched with the limiting member 280 and used for limiting the moving range of the cross rod 220 in the vertical rod 210.

The applicant considers that the height of the pressure lever 200 is suitable for people with different feet, in order to realize the height adjustment of the cross rod 220, a constructor can adjust the height of the cross rod 220 according to the foot type and the use habit, and then the clamping piece 290 and the limiting piece 280 are matched for limiting, so that the requirements of different constructors are met, and the applicability of products is improved.

Optionally, as shown in fig. 4, the limiting member 280 includes a sawtooth rack 250; the clamping piece 290 comprises an elastic component 260 which is matched with and positioned on the sawtooth strip 250; the sawtooth strip 250 comprises a plurality of regularly arranged sawtooth parts; each of the saw-tooth portions faces the elastic member 260; the sawtooth part comprises a first tooth edge arranged horizontally and a second tooth edge arranged obliquely; the openings of the serrations face the pedal 110.

The sawtooth itself possesses good spacing performance, and can be according to the regulation precision of the interval adjustment horizontal pole 220 between the sawtooth portion of difference, and the scheme is simple reliable.

Further, the elastic component 260 includes a first elastic sheet 230 matched with the sawtooth portion, a second elastic sheet 240 fixedly connected with the cross bar 220, and an adapter portion connecting the first elastic sheet 230 and the second elastic sheet 240; the adapter is rotatably fixed to the cross bar 220. The elastic stress of the elastic sheet can be tightly occluded with the sawtooth part, so that the limiting effect is improved.

Further, the cross bar 220 comprises a sleeve part 221 matched with the vertical bar 210; a stop block 211 is arranged at the top of the vertical rod 210; the outer diameter of the stopper 211 is larger than the inner diameter of the sleeve part 221; the adapter part is movably connected to the outer wall of the sleeve part 221; the outer wall of the sleeving part 221 is further provided with a positioning plate extending downwards, and the second elastic sheet 240 is in contact positioning with the positioning plate; magnets 270 are respectively arranged at the contact positions of the second elastic sheet 240 and the positioning plate. The stopper 211 has injectd the maximum height-adjusting of horizontal pole 220, and the portion of cup jointing 221 itself can increase the area of contact of horizontal pole 220 with montant 210, improves the stability of horizontal pole 220 location, reduces the instep when the ladder removes and moves the vibration that drives horizontal pole 220 along with footboard 110 focus, and when pushing down horizontal pole 220, first shell fragment 230 can be followed sawtooth portion and slided downwards just like the belt buckle. However, even if the cross bar 220 is forced upward, the cross bar will not slide upward, because the first resilient plate 230 will always contact with the saw teeth due to the attraction between the second resilient plate 240 and the two magnets 270 on the positioning plate, and because the resilient plate can only slide downward but cannot slide upward due to the teeth, the foot shape with any size can be locked. When the pressing rod 200 is to be retracted, the sawtooth strip 250 moves only by pulling the driving lever, so that the sawtooth part does not contact with the elastic sheet, and the cross bar 220 is bounced. Finally, the whole press rod 200 is rotated into the accommodating groove 120 of the balance car. Referring to fig. 2, when the cross bar 220 is stretched to the highest position, the cross bar 220 is separated from the locking groove 150, and the cross bar 220 is pressed down along the arc-shaped sidewall of the baffle 130, so that the cross bar 220 can be laid down and inserted into the receiving groove 120. The cross bar 220 is in a lying state, referring to fig. 3, at this time, there is no shelter above the pedal 110, and the utility model can be used as a common balance car.

The technical scheme of this application is applicable to various needs fixed foot and improves cat ladder or high altitude construction platform of security performance.

The foregoing is a more detailed description of the present application in connection with specific embodiments thereof, and it is not intended that the present application be limited to the specific embodiments thereof. For those skilled in the art to which the present application pertains, several simple deductions or substitutions may be made without departing from the concept of the present application, and all should be considered as belonging to the protection scope of the present application.
