[0029] Preferably, an active cavity 101b is provided below the accommodating groove 101a, and a partition 101c is provided between the accommodating groove 101a and the active cavity 101b.

[0030] Preferably, the outer wall of the column 102 is provided with a first inclined surface 102b, the outer wall of the first inclined surface 102b is provided with a first groove 102c, the outer wall of the movable column 103 is provided with a support ring 103a, one end of the movable column 103 is provided with a second inclined surface 103b, and the other end of the movable column 103 is provided with a third inclined surface 103c.

[0031] Preferably, a first protrusion 103b-1 is provided on the outer wall of the second inclined surface 103b, the first groove 102c is movably engaged with the first protrusion 103b-1, and a second protrusion 103c-1 is provided on the outer wall of the third inclined surface 103c.

[0033] Among them, the support ring 103 is set in two groups inside the movable cavity 101b, fixedly connected to the partition 101c, and plays a role in fixing and guiding the movable column 103; when the pedal 101 is pressed down, the column 102 is driven to descend, and under the active cooperation of the first inclined surface 102b and the second inclined surface 103b, the first protrusion 103b-1 slides in the first groove 102c, causing the movable column 103 to slide toward the accommodating cavity 201, and further the third inclined surface 103c and the fourth inclined surface 104a are actively cooperated, causing the second protrusion 103c-1 to slide in the second groove 104a-1, causing the receiving block 104b to drive the rack 104a to rise.

[0034] In summary, when the staff stands on the pedal 101, the first elastic member 102a is compressed, causing the pedal 101 to enter the accommodating groove 101a, and the column 102 pushes the movable column 103 to move toward the accommodating chamber 201, so that the connecting column 104 drives the rack 104a to rise, and the gear 202a-1 rotates, driving the push plate 202c-1 to push the moving plate 201b to move toward the middle of the accommodating chamber 201, so that the clamping plate 302 and the clamping column 302d cooperate and clamp, completing the fixation of the protective ring 201c and ensuring the safety of the staff.

[0035] Example 2, reference Figures 4 to 6 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the gear 202a-1 is engaged with the rack 105 to rotate the bevel disk 202b. Under the action of the matching column 202b-1, the push plate 202c-1 pushes the moving plate 201b to move to the middle of the accommodating cavity 201, thereby fixing and clamping the protective ring 201c, providing effective protection measures for the staff.

[0036] Specifically, a sliding groove 105a is provided on the outer wall of the rack 105, and a sliding bar 201d is provided on the inner wall of the accommodating cavity 201, and the sliding groove 105a and the sliding bar 201d are movably matched.

[0037] Preferably, a telescopic rod 201a-1 is provided between the fixed plate 201a and the moving plate 201b, and a second elastic member 201a-2 is sleeved on the outer wall of the telescopic rod 201a-1.

[0038] Preferably, a first support plate 202 and a second support plate 203 are provided inside the accommodating cavity 201 , a rotating shaft 202 a is provided between the first support plate 202 and the second support plate 203 , a gear 202 a - 1 is provided on the outer wall of the rotating shaft 202 a , and the gear 202 a - 1 is engaged with the rack 105 .

[0039] Among them, the slide bar 201d is symmetrically arranged in two groups and fixed on the inner wall of the accommodating cavity 201, which plays a guiding role for the sliding of the rack 105; when the connecting column 104 rises, the rack 105 slides upward under the cooperation of the slide groove 105 and the slide bar 201d; the second elastic member 201a-2 is a compression spring; the first support plate 202 and the second support plate 203 are used to fix the rotating shaft 202a, but do not affect the rotation of the rotating shaft 202a; when the rack 105 slides upward, The rotation of gear 202a-1 causes the rotating shaft 202a to rotate. Under the action of the bevel ring 202b and the matching column 202b-1, the push rod 202c drives the push plate 202c-1 to be pushed toward the moving plate 201b. The moving plate 201b moves toward the center of the accommodating chamber 201 due to the thrust of the push plate 202c-1. The second elastic member 201a-2 is stretched to move the protective ring 201c toward the middle, and further the clamping plate 302 is clamped with the clamping column 302d.

[0040] In summary, through the cooperation between the rack 105 and the gear 202a-1, the rotating shaft 202a drives the bevel ring 202b to rotate, and under the action of the cooperating column 202b-1, the push plate 202c-1 pushes the moving plate 201b to move toward the middle, thereby fixing and clamping the protective ring 201c, providing effective protection measures for the staff.

[0041] Example 3, reference Figures 1 to 6 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that when the push plate 202c-1 pushes the moving plate 201b, inertia causes the moving plate 201b to continue sliding toward the middle. At this time, the slot 302c and the column 302d are fixed to lock the protective ring 201c.

[0042] Specifically, a bevel ring 202b is provided on the outer wall of the rotating shaft 202a, and matching columns 202b-1 are provided on both sides of the bevel ring 202b. A push rod 202c is provided above the matching column 202b-1, and a push plate 202c-1 is provided on the outer wall of the push rod 202c. The push plate 202c-1 is movably matched with the moving plate 201b.

[0043] Preferably, a handle 302a is provided on the outer wall of the card plate 302, an arcuate surface 302b is provided on the outer wall of the card plate 302, a card slot 302c is opened on the outer wall of the card plate 302, and a card column 302d is provided inside the card slot 302c.

[0044] Among them, the bevel ring 202b is connected to the rotating shaft 202a as a whole, and the bevel ring 202b is set between the two matching columns 202b-1; the push rod 202c passes through the first support plate 202 and the second support plate 203; the protective ring 201c is symmetrically provided with two, one of which is provided with a clamping plate 302 and a limit plate 301 on the outer wall of the protective ring 201c, and the other is provided with a clamping column 302d on the outer wall of the protective ring 201c; in the initial state, there is a certain distance between the two protective rings 201c, which is convenient for When a worker steps on the pedal 101, the push plate 202c overlaps the moving plate 201b, and the telescopic rod 201a-1 is in a retracted state. When the push rod 202c is pushed, the push plate 202c applies a thrust toward the moving plate 201b, the telescopic rod 201a-1 extends, and the moving plate 201b moves toward the middle. Under the action of the locking assembly, the protective ring 201c is locked. At this time, the second elastic member 201a-2 is in a stretched state, and there is a certain distance between the moving plate 201b and the push plate 202c. When the staff leaves the climbing-free device body M, by unlocking the locking assembly and pushing the protective ring 201c, the moving plate 201b slides toward the rack 105 and overlaps the outer wall of the push plate 202c. At this time, the push plate 202c is still in the pushing state, and the telescopic rod 201a-1 and the second elastic member 201a-2 cannot completely return to the initial state and still have a certain degree of stretch. At this time, there is a certain gap between the two protective rings 201c, which allows the staff to leave the climbing-free device body M. When the staff's feet are When leaving the pedal 101, the first elastic member 102a is released, the column 102 rises, and with the cooperation of the movable column 103 and the connecting column 104a, the rack 105 descends, and the gear 202a-1 rotates in the opposite direction. Under the action of the bevel ring 202b and the matching column 202b-1, the push plate 202c is reset. Under the action of the telescopic rod 201a-1 and the second elastic member 201a-2, the moving plate 201b is driven back to the initial state, and the distance between the protective rings 201c becomes larger and reset to the initial state.

[0045] In summary, when the moving plate 201b moves toward the middle of the accommodating chamber 201, the two protective rings 201c move toward the middle at the same time. When the curved surface 302b touches the clamping column 302d, the clamping plate 302 rotates, and the two protective rings 201c move further, so that the clamping groove 302c and the clamping column 302d cooperate and clamp, completing the fixation of the protective ring 201c, providing protection for the safety of the staff. When it is necessary to pull open the anti-climbing device body M, the clamping plate 302 is pulled up by the handle 302a to disengage the clamping groove 302c from the clamping column 302d, and the protective ring 201c is pushed to both sides, so that the staff can leave at a certain distance.
