A foot buckle that can automatically change diameter

Abstract

The invention relates to climbers, in particular to a climber capable of achieving automatic diameter variation. The climber comprises a U-shaped rack, a pressure plate rack, a pressure plate, an arc-shaped plate, a foot rest component, a linkage lever, a fulcrum rod, a connecting rod I, a connecting rod II and a fulcrum rod slide rack, wherein the pressure plate rack is slidably connected to the left end of the U-shaped rack, the pressure plate is hinged to the right end of the pressure plate rack and located on the inner side of the U-shaped rack, the arc-shaped plate is hinged to the inner side of the right end of the U-shaped rack, the foot rest component is hinged to the outer side of the right end of the U-shaped rack, the foot rest component is hinged to one end of the connecting rod II, the other end of the connecting rod II is hinged to one end of the connecting rod I, the other end of the connecting rod I is hinged to the lower end of the linkage lever, the connecting rod I is slidably connected to the lower end of the U-shaped rack, and the middle end of the linkage lever is slidably hinged to one end of the fulcrum rod. The climber has the advantage that changing of distance between the pressure plate and the arc-shaped plate can be achieved under gravity to adapt to the diameter change of a telegraph pole during climbing.

Description

Technical field [0001] The invention relates to a foot buckle, more specifically, a foot buckle that can automatically change diameter. Background technique [0002] The foot buckle is a kind of arc iron tool that is put on the shoe and used to climb the telephone pole. It uses leverage and the self-locking phenomenon in mechanics to make the other side fasten to the telephone pole with the help of the body's own weight. As the weight on the foot is reduced when the foot is lifted, the foot buckle is automatically released. Traditional foot buckles can be adapted to poles of different diameters by adjusting the radial size before use. However, since the poles are usually of lower thickness and upper thin structure, the radial size of traditional foot buckles cannot be changed when climbing, which makes it impossible to adapt during climbing. The diameter of the pole changes, which causes inconvenience in use. [0003] For example, a non-slip foot buckle with patent application nu...

Problems solved by technology

The traditional foot buckle can adapt to different diameters of utility poles by adjusting the radial size before use. However, since the utility pole is usually a thicker bottom and a thinner structure, the radial dimension of the traditional foot buckle cannot be changed when climbing, which makes it impossible to adapt during the climbing process. The diameter of the utility pole varies, which causes inconvenience in use

[0003] For example, the patent application number is CN201511004158.7, which is a kind of anti-slip foot buckle, which includes an arc-shaped buckle body, a foot plate, a strap, and an adsorption component composed of the first and second clamping rods. The adsorption components are respectively connected to the first clamping rod and the At the outer end of the second clamping rod, the adsorption assembly includes a backboard, a supporting board, a hinge and an elastic anti-skid suction block. There are multiple air chambers on the anti-slip suction block, and the body of the supporting plate is provided with air holes communicating with the air chambers; this invention increases the adhesion between the foot buckle and the pole by adding an adsorption device, but it cannot solve the problem of the foot buckle. Inability to accommodate changes in pole diameter during climbing
