Abstract
Description
Technical Field
[0001] The invention relates to a foot buckle for pole climbing operations, in particular to an anti-slip foot buckle. Background Art
[0002] Foot buckles are arc-shaped iron tools that are put on shoes and used to climb electric poles. Foot buckles have the advantages of light weight, high strength, good toughness, lightness, flexibility, and easy to carry. Climbing electric poles with foot buckles is fast and easy. Foot buckles use the lever effect and the weight of the human body to make the other side tightly buckled on the electric pole, generating greater friction, making it easier for people to climb; and when the foot is lifted, the weight on the foot is reduced, and the buckle automatically loosens.
[0003] In order to prevent the foot from falling off the foot buckle during the pole climbing operation, holes or protrusions are usually set on the foot pedal to increase the friction between the foot pedal and the sole. Although the foot pedal with holes or protrusions can improve the friction between the foot pedal and the sole to a certain extent, which is helpful to prevent the foot from falling off the foot buckle; however, in cold weather conditions, especially in rainy and snowy weather under cold weather conditions, the surface of the foot pedal is prone to ice when the pole climber works on the pole for a long time. At this time, it is easy for the pole climber's feet to slip between the foot pedal, causing the pole climber's feet to fall off the foot buckle, affecting the pole climber's work safety. Summary of the invention
[0004] The purpose of the present invention is to provide an anti-slip foot buckle that can effectively prevent the pole climber's feet from slipping between the foot and the foot pedal, causing the pole climber's feet to fall off the foot buckle, affecting the pole climber's working safety.
[0005] The technical solution of the present invention is:
[0006] An anti-slip foot buckle comprises a foot pedal and an anti-slip device, wherein the anti-slip device comprises:
[0007] An elastic rubber plate, the upper surface of which is provided with a plurality of evenly arranged limiting holes, the elastic rubber plate is fixed to the lower surface of the foot pedal, and the foot pedal is provided with a plurality of floating rod guide holes corresponding to the limiting holes one by one;
[0008] The floating rod corresponds to the limiting hole one by one, the lower end of the floating rod is fixed in the corresponding limiting hole, and the upper end of the floating rod passes through the corresponding floating rod guide hole and is located above the foot pedal.
[0009] In the anti-slip foot buckle of the present scheme, since there are several evenly arranged floating rods distributed on the foot pedal, and the lower end of the floating rod is provided with a limiting hole for fixing the elastic rubber plate, when the shoe of the pole climber steps on the foot pedal, the upper end of a part of the floating rod will move down along the floating rod guide hole into the floating rod guide hole, so that the shoe of the pole climber steps on the upper surface of the foot pedal, and another part of the floating rod will be stuck in the groove of the sole pattern (the sole generally has a concave and convex pattern). When the shoe is lifted, the floating rod moves upward under the action of the elastic rubber plate, so that a part of the floating rod remains stuck in the groove of the sole pattern. In this way, even in rainy and snowy weather under cold climate conditions, it can effectively prevent the pole climber's foot from slipping with the foot pedal, which may cause the pole climber's foot to fall off the foot buckle and affect the pole climber's working safety.
[0010] More importantly, when the pole climber's shoes step on the foot pedal, the floating rod will move downward along the floating rod guide hole, and when the pole climber's shoes are lifted and the soles are separated from the foot pedals, the floating rod will move upward under the action of the elastic rubber plate, that is, the floating rod will continue to move up and down during the pole climbing process; in this way, even when working in rainy and snowy weather under cold climate conditions, the up and down movement of the floating rod during the pole climbing process can be used to timely destroy the ice layer formed on the upper surface of the foot pedal, so as to avoid the formation of thicker ice on the upper surface of the foot pedal, thereby further effectively avoiding the problem of slipping between the pole climber's feet and the foot pedal due to ice on the surface of the foot pedal, causing the pole climber's feet to fall off the foot buckles.
[0011] Preferably, the elastic rubber plate is provided with an inner plate cavity, and each of the limiting holes is located above the inner plate cavity. In this way, not only can the elasticity of the lower part of the elastic rubber plate where the lower end of the floating rod is located be improved, so as to facilitate the floating rod to move up and down at the elastic rubber plate; but the inner plate cavity can also play a role in heat insulation, and in cold weather conditions, the elasticity of the elastic rubber plate where the lower end of the floating rod is located is ensured, so that the floating rod can move up and down under the elastic action of the elastic rubber plate.
[0012] Preferably, an annular groove corresponding to the limiting hole is further provided on the top surface of the inner cavity of the plate, and the lower end of the limiting hole is located in the corresponding annular groove. In this way, the elasticity below the elastic rubber plate where the lower end of the floating rod is located can be further improved, so as to facilitate the floating rod to move up and down at the elastic rubber plate.
[0013] Preferably, the upper end surface of the floating rod is a guiding inclined surface, and the side of the guiding inclined surface close to the rear end of the foot pedal is inclined downward. In this way, on the one hand, it is convenient for the upper end of the floating rod to be stuck in the groove of the shoe sole pattern to avoid slipping between the foot of the pole climber and the foot pedal; on the other hand, when the shoe is inserted into the pedal buckle of the foot pedal, if the sole of the shoe contacts the guiding inclined surface of the upper end of the floating rod, it is convenient for the floating rod to move downward, so that the shoe is inserted into the pedal buckle of the foot pedal.
[0014] Preferably, the inclination angle of the guiding slope is 20-40 degrees.
[0015] Preferably, the floating rod comprises a floating bottom rod and an upper clamping rod arranged at the upper end of the floating bottom rod, wherein the outer diameter of the upper clamping rod is smaller than the outer diameter of the floating bottom rod, and the floating bottom rod extends into the floating rod guide hole. In this way, on the one hand, the floating stability and strength of the floating rod can be improved by cooperating with the floating bottom rod with a larger outer diameter and the floating rod guide hole, and it can also be convenient for the upper clamping rod with a smaller outer diameter to be clamped into the groove of the shoe sole pattern to avoid slipping between the feet of the pole climbing worker and the foot pedal; on the other hand, the floating bottom rod with a larger outer diameter is matched with the floating rod guide hole to increase the aperture of the floating rod guide hole, which is conducive to breaking the ice layer on the upper surface of the foot pedal when working in rainy and snowy weather under cold climate conditions.
[0016] Preferably, the upper end of the floating bottom bar is located above the upper surface of the pedal, and the distance between the upper end of the floating bottom bar and the upper surface of the pedal is less than or equal to 1 mm. In this way, the floating bottom bar is conducive to breaking the ice layer on the upper surface of the pedal.
[0017] Preferably, the distance between the top end of the floating rod and the upper surface of the foot pedal is 3-6 mm.
[0018] Preferably, the device further comprises a knee connecting belt, one end of which is connected to the foot pedal, and the other end of which is provided with a knee buckle, so that the knee buckle can be fixed to the knee attachment of the pole climbing worker through the knee buckle, and the foot buckle can be connected to the pole climbing worker through the knee connecting belt to prevent the foot buckle from falling off.
[0019] Preferably, the upper surface of the elastic rubber plate is in close contact with the lower surface of the foot pedal.
[0020] The beneficial effect of the present invention is that it can effectively prevent the pole climber's feet from slipping against the foot pedals, thereby preventing the pole climber's feet from falling off the foot buckles and affecting the pole climber's working safety.

[0032] Specific embodiment 1: Figure 1 , Figure 2 As shown, an anti-slip foot buckle includes a foot pedal 1 and an anti-slip device 2. The anti-slip device 2 includes an elastic rubber plate 2.0 and a floating rod 2.1. The upper surface of the elastic rubber plate is provided with a plurality of evenly arranged limiting holes 2.5. The elastic rubber plate is fixed on the lower surface of the foot pedal. Specifically, the upper surface of the elastic rubber plate is tightly attached to the lower surface of the foot pedal. In this embodiment, the upper surface of the elastic rubber plate is attached to the lower surface of the foot pedal. The foot pedal is provided with a plurality of floating rod guide holes 2.2 corresponding to the limiting holes one by one. The floating rod guide holes penetrate the upper and lower surfaces of the foot pedal. The floating rod corresponds to the limiting holes one by one. The lower end of the floating rod is provided and fixed in the corresponding limiting hole, and the upper end of the floating rod passes through the corresponding floating rod guide hole and is located above the foot pedal. In this embodiment, the upper surfaces of the floating rod foot pedal are perpendicular.
[0033] In the anti-slip foot buckle of the present embodiment, since a number of evenly arranged floating rods are distributed on the foot pedal, and the lower end of the floating rod is provided with a limiting hole for fixing the elastic rubber plate, when the pole climber's shoe steps on the foot pedal, a part of the upper end of the floating rod will move down along the floating rod guide hole into the floating rod guide hole, so that the pole climber's shoe steps on the upper surface of the foot pedal, and a part of the floating rod will be stuck in the groove of the sole pattern (the sole generally has a concave and convex pattern). When the shoe is lifted, the floating rod moves upward under the action of the elastic rubber plate, so that a part of the floating rod remains stuck in the groove of the sole pattern. In this way, even in rainy and snowy weather under cold climate conditions, it can effectively prevent the pole climber's foot from slipping with the foot pedal, which may cause the pole climber's foot to fall off the foot buckle and affect the pole climber's working safety.
[0034] More importantly, when the pole climber's shoes step on the foot pedal, the floating rod will move downward along the floating rod guide hole, and when the pole climber's shoes are lifted and the soles are separated from the foot pedals, the floating rod will move upward under the action of the elastic rubber plate, that is, the floating rod will continue to move up and down during the pole climbing process; in this way, even when working in rainy and snowy weather under cold climate conditions, the up and down movement of the floating rod during the pole climbing process can be used to timely destroy the ice layer formed on the upper surface of the foot pedal, so as to avoid the formation of thicker ice on the upper surface of the foot pedal, thereby further effectively avoiding the problem of slipping between the pole climber's feet and the foot pedal due to ice on the surface of the foot pedal, causing the pole climber's feet to fall off the foot buckles.
[0035] In this embodiment, the floating rods are evenly arranged and distributed. The floating rods are arranged in 6-10 rows from the front end of the foot pedal to the rear end of the foot pedal. Specifically, the floating rods are arranged in 7 rows from the front end of the foot pedal to the rear end of the foot pedal. Each row of floating rods includes 8-12 floating rods.
[0036] Further, such as Figure 2 As shown, the elastic rubber plate is provided with a plate cavity 2.3, and each limiting hole is located above the plate cavity. In this way, not only can the elasticity of the lower part of the elastic rubber plate where the lower end of the floating rod is located be improved, so as to facilitate the floating rod to move up and down at the elastic rubber plate; but the plate cavity can also play a role in heat insulation, and in cold weather conditions, the elasticity of the elastic rubber plate where the lower end of the floating rod is located is ensured, so that the floating rod can move up and down under the elastic action of the elastic rubber plate.
[0037] Further, such as Figure 2 As shown, an annular groove 2.4 corresponding to the limiting hole is also provided on the top surface of the inner cavity of the plate. The lower end of the limiting hole is located in the corresponding annular groove. In this way, the elasticity below the elastic rubber plate where the lower end of the floating rod is located can be further improved, so as to facilitate the floating rod to move up and down at the elastic rubber plate.
[0038] Further, such as Figure 2 As shown, the floating rod 2.1 includes a floating bottom rod 2.11 and an upper clamping rod 2.12 arranged at the upper end of the floating bottom rod. The floating bottom rod extends into the floating rod guide hole. The outer diameter of the upper clamping rod is smaller than the outer diameter of the floating bottom rod. In this way, on the one hand, the floating stability and strength of the floating rod can be improved by cooperating with the floating bottom rod with a larger outer diameter and the floating rod guide hole, and it can also be convenient to clamp the upper clamping rod with a smaller outer diameter into the groove of the shoe sole pattern to avoid slipping between the feet of the pole climbing workers and the pedals; on the other hand, the floating bottom rod with a larger outer diameter cooperates with the floating rod guide hole to increase the aperture of the floating rod guide hole, which is conducive to breaking the ice layer on the upper surface of the pedal when working in rainy and snowy weather under cold climate conditions.
[0039] The upper end of the floating bottom bar is located above the upper surface of the pedal, and the spacing between the upper end of the floating bottom bar and the upper surface of the pedal is less than or equal to 1 mm. In this way, the floating bottom bar is conducive to breaking the ice layer on the upper surface of the pedal.
[0040] Further, such as Figure 2 , Figure 3 As shown, the upper end surface of the floating rod is a guiding bevel 2.13, specifically, the upper end surface of the upper clamping rod of the floating rod is a guiding bevel 2.13. The side of the guiding bevel close to the rear end of the foot pedal is inclined downward. The inclination angle of the guiding bevel is 20-40 degrees. In this embodiment, the inclination angle of the guiding bevel is 30 degrees. In this way, on the one hand, it is beneficial for the upper end of the floating rod to be stuck in the groove of the sole pattern to avoid slipping between the feet of the pole climber and the foot pedal; on the other hand, in the process of the shoe extending into the pedal buckle of the foot pedal, if the sole contacts the guiding bevel at the upper end of the floating rod, it is beneficial for the floating rod to move downward, so that the shoe can be extended into the pedal buckle of the foot pedal.
[0041] The distance between the top end of the floating rod and the upper surface of the footrest is 3-6 mm.
[0042] Furthermore, the anti-slip foot buckle also includes a knee connecting belt (not shown in the figure). One end of the knee connecting belt is connected to the foot pedal, and the other end of the knee connecting belt is provided with a knee buckle. In this way, the knee buckle can be fixed to the knee attachment of the pole climbing worker through the knee buckle, and the foot buckle can be connected to the pole climbing worker through the knee connecting belt to prevent the foot buckle from falling off.
[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
