The rope fixing base strengthens the connection of the rope and the iron chain and prevents the rope from being separated from the iron chain.

Referring to fig. 1 and 5, a slip pad 6 is installed at the bottom end of the main lever 1. The anti-skid pad further enhances the anti-skid function of the ladder.

Referring to fig. 2 and 3, the insert rod assembly 4 includes a short rod 7 horizontally disposed and having one end fixedly connected to the bottom of the main rod 1, and a through groove 8 is provided in the middle of the short rod 7; the inserted link 9 is vertically arranged and is in sliding connection with the short link 7, and the inserted link 9 is in sliding connection with the short link 7 in the through groove 8; the top of the inserted link 9 is provided with an inserted link cap 13, a clearance groove for accommodating a torsion spring 16 is arranged between the inserted link cap 13 and the inserted link 9, and one end of a limiting rod 14 is movably sleeved on the inserted link cap 13; the torsion spring 16 is respectively abutted with the top of the inserted link 9 and the limit link 14, and two ends of the torsion spring 16 are respectively and coincidently arranged in spring tip grooves in the top of the inserted link 9 and the limit link 14. When the limiting rod 14 rotates in the direction away from the connecting sheet 15, the torsion spring 16 stores force in the rotation process of the limiting rod 14, and always gives the restoring force to the limiting rod 14, namely gives the restoring force to the limiting rod 14 in the direction close to the connecting sheet 15, so that the stability of the limiting rod 14 in the horizontal direction is ensured; and a limiting piece arranged on the short rod 7 to cooperate with the other end of the limiting rod 14 to limit the sliding of the inserted rod 9 in the vertical direction.

Referring to fig. 2, the stopper includes a connection piece 15, an upper stopper 11, and a lower stopper 12.

A connecting piece 15 vertically provided at the upper part of the stub 7. The position of the connecting piece is based on satisfying the effect of sliding the inserting rod 9 in the through groove, and the connecting piece can be close to the inserting rod 9 as much as possible, so that the limiting effect can be better, if the connecting piece is arranged on the upper part of the rear end of the short rod 7, the width of the limiting rod 14 needs to be increased, and the large limiting rod 14 is ensured to be parallel to the short rod 7 in the reset state.

The upper limit frame 11 is arranged at the upper end of the connecting sheet 15 and is matched with the limit rod 14 for limit.

The lower limit frame 12 is arranged at the lower end of the connecting sheet 15 and is matched with the limit rod 14 for limit.

The upper limit frame 11 and the lower limit frame 12 are welded on the same longitudinal line of the connecting sheet 15, and have the same structure. The upper limit frame 11 and the lower limit frame 12 are internally provided with grooves, openings are arranged along the front ends of the grooves, and the sizes of the openings are matched with the radial diameters of the limit rods 14. Of course, the upper limit frame 11 or the lower limit frame 12 can be split into two small parts, and the opposite ends of the small parts are arranged into spaces with the diameter of the limit rod 14 being matched with that of the radial direction. Or, the upper limit frame 11 or the lower limit frame 12 is provided with a bolt and other structures for further limit.

Further, the limiting structure is not limited to this manner, as long as the limiting structure is satisfied that the limiting rod 14 does not generate any displacement under the action of the limiting structure. Because the stop lever 14 indirectly drives the plunger assembly 4 to be unstable when displaced.

Since the upper part of the inserted link 9 is the lowest cross bar 2, the length of the inserted link 9 is smaller than the longitudinal distance between the lowest cross bar 2 and the short bar 7, so that the inserted link 9 does not leave the through groove during the upward sliding process.

The process of fitting the insert rod 9 with the short rod 7 slidingly connected is as follows: when the ladder is retracted and not used, the inserting rod 9 slides upwards relative to the short rod 7 in the through groove 8, the limiting rod 14 is in limiting fit with the upper limiting frame 11, the limiting rod 14 is clamped by the upper limiting frame 11, and meanwhile, the torsion spring 16 gives the elastic force for the limiting rod 14 to draw close to the connecting sheet direction all the time, so that the stability of the limiting rod 14 in the horizontal direction is improved. At this time, the tip of the sliding rod 9 does not exceed the bottom ends of the two main rods 1, so that the tip of the inserting rod 9 is prevented from injuring staff by mistake.

When the ladder is used, the inserted link 9 slides downwards relative to the short link 7 in the through groove 8, and the limiting link 14 is in limiting fit with the lower limiting frame 12. The limiting rod 14 is clamped by the upper limiting frame 11, and meanwhile, the torsion spring 16 gives the elastic force for the limiting rod 14 to always point to the connecting sheets to be close, so that the stability of the limiting rod 14 in the horizontal direction is improved. At this time, the tip of the insertion rod 9 exceeds the bottom end of the main rod 1, and the insertion rod 9 is inserted into the mine tunnel floor.

Example 2

This embodiment differs from embodiment 1 in that the short rod 7 and the insert rod 9 in the insert rod assembly 4 of embodiment 1 are slidably connected, and the short rod 7 and the insert rod 9 in the insert rod assembly 4 of this embodiment are screw-connected.
