Description

Technical Field

[0001] The invention relates to the technical field of climbing anti-skid foot buckles, and in particular to a variable-diameter anti-skid foot buckle. Background Art

[0002] Foot buckles, also known as climbing safety foot buckles, are irreplaceable pole climbing tools in the power industry. The current foot buckle principle is to use the lever effect and the weight of the human body to make the other side tightly buckled on the pole body, generating greater friction, making it easier for people to climb; but there are still the following problems in actual use: in the south, where there is a lot of rain, the pole body is prone to moss growth, or in frosty weather, the surface of the pole is frost or thin ice, which is particularly smooth, and the rubber on the existing foot buckle body will harden at low temperatures, which is easy to slip and fall during climbing or high-altitude operations. Therefore, the existing foot buckles are not safe and reliable to use in situations such as after rain, when the pole body is mossy, or when frost or thin ice accumulates on the surface of the pole body. Summary of the invention

[0003] In order to solve the defects of the prior art, the present invention provides a variable diameter anti-skid foot buckle, which can solve the problems of anti-skid and safety under the above environmental conditions.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A variable-diameter anti-skid foot buckle comprises a first buckle body and a second buckle body, wherein the first buckle body and the second buckle body are both arc-shaped structures, and the second buckle body is telescopically and adjustably connected to the first buckle body; a telescopic foot pedal assembly is arranged at the end of the first buckle body; a plurality of clamping blocks are arranged on the second buckle body; the telescopic foot pedal assembly comprises a sliding seat and a foot pedal, and the foot pedal can be movably arranged in the sliding seat along the upper and lower directions; the foot pedal is connected to the clamping block through a tractor; the downward displacement of the foot pedal will drive the clamping block to extend toward the inner side of the second buckle body, thereby realizing the squeezing of the climbing object by the clamping block.

[0006] Optionally, the slide seat is arranged to be inclined along the inner and outer directions.

[0007] Optionally, the traction device is a rope.

[0008] Optionally, the pressing block is rotatably disposed on the second buckle body, and the downward displacement of the pedal drives the pressing block to rotate via a traction device, and causes the pressing block to extend toward the inner side of the second buckle body.

[0009] Optionally, the rope is connected to the inner end side of the pressing block, and the pressing block is rotated by pulling the rope.

[0010] Optionally, the slide seat includes a left slide seat and a right slide seat, and the left slide seat and the right slide seat are respectively provided with slide grooves, and a sliding cross bar is slidably provided between the two slide grooves; the foot pedal is provided at the outer end of the sliding cross bar, and a pressure rod is provided at the inner end thereof.

[0011] Optionally, a friction block is movably provided at the inner end of the pressure rod.

[0012] Optionally, a plurality of insertion holes are correspondingly provided on the two slide grooves, and a limit insertion rod is detachably provided on the insertion holes.

[0013] Optionally, when the sliding cross bar is located at the highest position of the slide seat, in a top view, the inner end of the pressure rod protrudes from the lower end of the slide seat.

[0014] Optionally, a friction layer is provided at the end of the pressing block.

[0015] The beneficial effects of the present invention are:

[0016] When in use, the foot buckle of the present invention is put on the rod body, and it is slightly tilted as in the conventional foot buckle (the principle is different, and the inclination of the device can be smaller than that of the conventional foot buckle in actual use), and then the sliding cross bar is caused to move downward by the weight of the human body, and then the plurality of clamping blocks are driven by the rope to extend toward the rod body and squeeze the rod body. During the downward displacement of the pressure bar of the foot buckle, the pressure bar is also displaced toward the rod body, and then the friction block of the pressure bar and the plurality of clamping blocks squeeze the rod body from the front and back sides respectively. Compared with the conventional foot buckle, the advantage is that the friction block and the plurality of clamping blocks squeeze the rod body, and the contact point can obtain a higher pressure. For situations such as after rain, when the rod body is covered with moss, or when frost and thin ice accumulate on the surface of the rod body due to frost, it can provide a better gripping force, significantly reduce the phenomenon of slipping and accidents that occur during climbing with the foot buckle and maintaining high-altitude operations, and improve the safety of outdoor operations.

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0026] like Figures 1 to 6 As shown, a variable diameter anti-skid foot buckle includes a first buckle body 1 and a second buckle body 4, wherein the first buckle body 1 and the second buckle body 4 are both arc-shaped structures, and the second buckle body 4 is telescopically adjustable to the first buckle body 1 so as to adapt to poles of different diameters to be climbed; a telescopic footrest assembly is provided at the end of the first buckle body 1; and a plurality of clamping blocks 3 are provided on the second buckle body 4.

[0027] The telescopic footrest assembly includes a slide 9 and a footrest 5, and the footrest 5 can be movably arranged in the slide 9 along the upper and lower positions; in this embodiment, the following scheme is specifically preferred:

[0028] The slide seat includes a left slide seat and a right slide seat. Figure 2 As shown, the left slide and the right slide are respectively provided with slide grooves, and a sliding cross bar 6 is slidably provided between the two slide grooves; then sliding connection blocks are respectively provided at the left and right ends of the sliding cross bar 6, and the sliding connection blocks are inserted into the slide grooves to realize that the sliding cross bar 6 can move freely up and down; and the outer end of the sliding cross bar 6 is connected to the foot pedal 5 through the first connecting rod 10, and the inner end of the sliding cross bar 6 is connected to the pressure rod 8. In order to improve the gripping force and friction force, in this embodiment, a friction block 7 can also be rotatably connected to the inner end of the pressure rod 8 through a rotating shaft 14; in some embodiments, a friction layer 15 is provided on the inner end surface of the friction block 7. In order to improve the smoothness of the foot lifting operation during the climbing process, in this embodiment, as Figures 1-2As shown, a plurality of plug holes 6-2 are correspondingly arranged on the two slide grooves, and a limit plug rod 11 is detachably arranged on the plug hole 6-2. The limit plug rod 11 can be specifically made of bolts. When the bolts are inserted and fixed, a nut is arranged at one end to lock it. The functions of this design are as follows:

[0029] When in use, the limit rod 11 is inserted into a suitable position and fixed at the beginning, so that when the technician lifts his feet during climbing, the limit rod 11 can limit the upper end of the sliding cross bar 6 in time to ensure the smoothness of the climbing and lifting operation.

[0030] Optional, such as Figure 1 As shown, when the sliding cross bar 6 is located at the highest position of the slide seat 9, in the top view, the inner end of the pressure rod 8 protrudes from the lower end of the slide seat 9. The purpose of this design is to ensure that the pressure rod 8 can smoothly contact the rod body when in use.

[0031] The footrest 5 is connected to the clamping block 3 through a traction device; the downward displacement of the footrest 5 drives the clamping block 3 to extend toward the inner side of the second buckle body, thereby achieving the compression of the clamping block 3 on the climbing object such as the rod 20. In this embodiment, the traction device is a rope 14. To improve durability, a steel wire rope can be preferably used. The specific diameter can refer to the standard adult weight and is preferably above 2.5 mm. Taking a stainless steel wire rope with a specification of 7*7 as an example, a reasonable load-bearing capacity of 2.5 mm in diameter is nearly 90 kg.

[0032] Optional, such as Figure 2 As shown, the slide seat 9 is tilted along the inner and outer directions, and is connected and fixed to the first buckle body 1 through the upper reinforcing plate 12 and the lower reinforcing plate 13. The purpose of this design is to enable the pressure rod 8 to move inward, that is, toward the rod body 20, during the downward displacement of the rear pressure rod 8, thereby gradually increasing the pressure applied by the friction block 7 to the rod body 20.

[0033] Optionally, the pressing block 3 can be rotatably arranged on the second buckle body 4. In this embodiment, the following scheme is adopted: Figure 3As shown, the top view of the clamping block 3 is similar to the top view of the cam, and an axial hole is provided in the middle of the clamping block 3, which is then fixed to the second buckle body 4 through a rotating shaft 16. An opening 19 is provided on the inner ring side of the second buckle body 4, and the protruding part of the clamping block 3 passes through the opening 19 and can swing freely. In some instances, a reset spring (not shown) may also be provided on the rotating shaft 16, and the reset spring is used to reset the rotating clamping block 3. The rope 14 is connected to the inner end side of the clamping block 3, and the following scheme may be adopted when making the connection: an arc-shaped through hole is horizontally provided on the inner end side of the clamping block 3, and then the rope 14 passes through the arc-shaped through hole and a limit block 18 is provided on the rear end side of the arc-shaped through hole, and the limit block 18 is tightly connected to the rope 14, so that when the rope 14 is pulled to the front side, the clamping block 3 can be caused to rotate; as shown in FIG. Figure 2 As shown, the end of the rope 14 passes through the lower opening 15 of the first buckle body 1 and is connected to the sliding cross bar 6. The displacement of the sliding cross bar 6 will cause the rope 14 to move, thereby pulling the pressing block 3 to rotate.

[0034] In order to reduce the slipping phenomenon in the case of moss growing on the rod body or frost and thin ice on the surface of the rod body after rain, in this embodiment, Figure 4 As shown, the contact portion of the pressing block 3 is provided with scraping teeth 17 to improve the scraping effect on the frost or ice surface.

[0035] The advantages of adopting this solution are: (1) in actual operation, the tension of the rope 14 is relatively large, and the force acting on the pressing block 3 is also relatively large, so the structure has good reliability and long service life. (2) the inner cavity space of the second buckle body 4 is limited, and compared with the solution of knotting the steel wire rope and the pressing block 3, the structure occupies less space and is smoother in actual use.

[0036] When in use, the telescopic degree of the first buckle body 1 and the second buckle body 4 is adjusted according to the diameter of the rod body 20 that needs to be climbed. At this time, if the rope 14 is stretched, the sliding cross bar 6 will be pulled up, and during processing and setting, the maximum adjustment degree of the first buckle body 1 and the second buckle body 4 is matched with the movable stroke of the sliding cross bar 6. After the telescopic degree of the first buckle body 1 and the second buckle body 4 is adjusted, it is tightened through the locking block 2. At the same time, the limiting plug rod 11 is passed through and fixed to the upper end of the sliding cross bar 6 to limit it. At this time, the foot buckle of the present invention is sleeved on the rod body 20, and the climbing is completed. During the process, the human body applies gravity to the sliding cross bar 6, and the sliding cross bar 6 moves downward (the displacement amplitude is the rotation amplitude of the pressing block 3 rotating together to press the rod body 20, that is, because the telescopic degrees of the first buckle body 1 and the second buckle body 4 have been adjusted according to the diameter of the rod body 20 in the early stage, the displacement amplitude will not be very large at this time), thereby prompting the friction block 7 to apply pressure to the rod body 20. At the same time, under the traction of the rope 14, a number of the pressing blocks 3 rotate, and together with the friction block 7, the rod body 20 is pressed and clamped from the front and rear directions. The clamping pressure on the rod body 20 is as follows: Figure 5 As shown, the plurality of pressing blocks 3 are pulled by ropes 14 to form a vertical F1' perpendicular to the rod body 20. 压 , and the friction block 7 forms F2' perpendicular to the rod body 20 压 , while F1` 压 and F2` 压 Directly from the gravity of the human body. Use the existing foot buckle to Figure 6 As shown in the analysis, under the action of human body weight, the existing foot buckle tilts along the front and back directions and exerts a component force F1 on the rod body 20. 压 and F2 压 , therefore, it is easy to derive |F1` 压 |+|F2` 压 |Greater Than|F1 压 |+|F2 压 |, in particular, the plurality of the pressing blocks 3 of the present invention can scrape the ice surface of the rod body 20 during the rotation process and the force is dispersed on the plurality of the pressing blocks 3, while F1` 压 It is converted into a point of the pressing block 3, and the traditional foot buckle F1 is used 压 It is the pressure of a force-bearing surface. Therefore, the present invention can achieve better gripping force, better anti-slip effect, and is safer and more reliable to use.
