Description

Technical Field

[0001] This utility model belongs to the technical field of insulating foot buckles, specifically a quick-wearing, anti-fall-off insulating pole climbing foot buckle. Background Technology

[0002] Electrician climbing poles is a crucial tool for electricians, widely used in power, telecommunications, and other industries for line maintenance and repair. It is mainly divided into wooden pole climbing poles and concrete pole climbing poles. The former has metal teeth on the loops and is suitable for climbing wooden poles; the latter has rubber-coated loops and is used for climbing concrete poles. The working principle is based on leverage and mechanical self-locking; the user's own weight creates friction by gripping the pole tightly on one side, thus enabling safe climbing.

[0003] While foot straps play a crucial role in actual operations, their current application has several shortcomings. Regarding insulation protection, the parts of existing foot straps that contact the climber's insulated shoes are mostly made of non-insulating materials such as iron or leather. When the insulated shoes become damp, workers are highly susceptible to electric shock if they accidentally touch live wires, guy wires, or crossarms, endangering their lives. Furthermore, due to a lack of comprehensive supervision, some personnel do not wear insulated shoes as required, increasing the risk of electric shock when accidentally touching live wires. In addition, the insulation of meter boxes on some utility poles in certain counties is easily aged and damaged due to prolonged exposure to wind and sun. Even if a voltage check shows no leakage before climbing, it cannot be guaranteed that touching these insulated wires during the climb will not cause leakage.

[0004] The existing foot straps only have a 2.5 cm wide leather strap on the instep of each iron shoe, which is fixed to the foot pedal. If the straps are not securely fastened when climbing up or down utility poles, the entire foot strap can easily detach from the foot. If someone is supervising, rescue can be obtained in a short time. If no one is supervising, one can only wait or risk sliding down the utility pole little by little. Many field workers have had similar experiences.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a quick-release, anti-fall-off, insulated pole climbing foot strap. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a quick-release, anti-fall-off, insulated pole climbing foot buckle, which solves the problem that the foot buckle fixing part in the prior art is relatively simple and connected, making it easy for the foot buckle to detach from the foot as a whole.

[0007] A quick-release, anti-fall-off, insulated pole climbing foot strap includes: a shoe cover, wherein an insole is installed inside the shoe cover;

[0008] The foot buckle has a connecting rod fixedly connected to its periphery, a connecting plate fixedly connected to the end of the connecting rod, and a rear pressure plate fixedly connected to the side wall of the connecting plate.

[0009] The connecting strap includes a first connecting strap, a second connecting strap, and a swivel roller. The first connecting strap is connected to one side of the shoe cover, and the second connecting strap is connected to the other side of the shoe cover. A swivel roller is installed at the end of the first connecting strap. The swivel roller has a plurality of toothed protrusions arranged around its periphery. The second connecting strap is connected to the swivel roller. Velcro is provided on the surface of the second connecting strap.

[0010] Preferably, the shoe cover has positioning grooves and perforations on both sides. The positioning grooves have several connecting holes. A pad is connected to the inner wall of the positioning groove. The first connecting strap and the second connecting strap both pass through the connecting holes, and one end of the first connecting strap and the second connecting strap is connected to the pad. A nylon expansion tube is installed between the first connecting strap and the second connecting strap and the pad. The nylon expansion tube passes through the connecting hole. A positioning sleeve is also installed around the second connecting strap.

[0011] Preferably, the pad includes a short pad and a long pad, the short pad being connected to the side near the second connecting strip, and the long pad being connected to the side near the first connecting strip; a plurality of nylon expansion tubes are installed between the first connecting strip and the long pad, and a plurality of nylon expansion tubes are installed between the second connecting strip and the short pad.

[0012] Preferably, the surface of the shoe cover has several conical holes, and several first nylon bolts are installed between the conical holes and the connecting plate.

[0013] Preferably, the insole surface has several mounting holes, the shoe cover surface has several positioning holes, and a second nylon bolt is installed between the mounting holes and the positioning holes.

[0014] Preferably, the end of the shoe cover is provided with an ankle connecting part, and an ankle groove is formed between the ankle connecting part and the shoe cover.

[0015] Preferably, the connecting strip is made of polyester fiber, and the pad is made of synthetic resin.

[0016] Preferably, a first stitch is provided between the Velcro and the connecting strap, and a second stitch is provided between the pad and the connecting strap.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention, by incorporating foot buckles, shoe covers, and connecting straps, ensures a secure connection between the shoe cover and the foot. The toothed protrusions on the rollers generate significant friction when the second connecting strap is tightened, further enhanced by Velcro fastening. This effectively solves the problem of foot buckles easily detaching from the foot in existing technologies, greatly improving the safety of pole climbing operations. The shoe cover can be used without removing shoes, its shape conforms to rubber shoes, and its bottom is made of a rigid insulating board, increasing the contact area with the foot. This makes the worker feel as if they are standing on the ground, effectively improving comfort. The semi-enclosed holes at the heel of the shoe cover, combined with widened straps, prevent slippage. All contact areas with the climber are made of electrically insulating material to prevent electric shock. The large contact area between the sole and the climber's shoe further enhances comfort, significantly improving the safety and comfort of power workers climbing concrete poles at heights.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 4As shown: This utility model provides a quick-wearing, anti-fall-off, insulated pole climbing foot buckle, including a foot buckle 1, a shoe cover 2, and a connecting strap 4;

[0027] As attached Figure 3 As shown: Shoe cover 2 contains an insole 3. Shoe cover 2 is 240 mm long, with a maximum heel height of 90 mm, a minimum toe height of 7 mm, a widest point at the ball of the foot of 130 mm, and a narrowest point at the heel of 110 mm. Both the front and back ends are semi-circular. The overall shape basically matches the shape of ordinary insulating shoes or narrow-legged athletic shoes (sizes 39-43, 10 kV and below) worn by pole climbers. Shoe cover 2 does not require pole climbers to remove their shoes; workers can simply slip their existing shoes over the insulating shoe cover. Shoe cover 2 is left- or right-handed; the toe of the insulating shoe cover 2 faces forward. The roller buckle 403 tightens from the inside of the shoe cover towards the left and from the right towards the right for the left foot. The bottom of shoe cover 2 is a rigid insulating board, providing a large contact area with the foot. Workers standing on the buckle feel as if they are standing on the ground, greatly improving comfort.

[0028] Each insulating shoe cover 2 has four M8.5 conical holes 201 on its bottom, aligned with four φ6.5 pressure-resistant pad positioning holes 202. Each insulating shoe cover has three Φ4 pad rivet holes 207 on each side wall, secured with six φ3.7 plastic rivet fasteners 208 to connect the insulating shoe cover 2 to pads 501 and 502. The side wall has rectangular through holes 206 (42×6×5 mm) for connecting straps 401 and 402, which are inserted into the side wall of the insulating shoe cover and then sewn together with nylon thread 402c. The side wall has rectangular pad inlay grooves 205 (70×3×10 mm) for embedding the long pads 502 and short pads 501 into the outer side wall of the shoe cover for aesthetic purposes.

[0029] As attached Figure 2 As shown: A connecting rod 101 is fixedly connected to the side of the foot buckle 1, and a connecting plate 103 is fixedly connected to the end of the connecting rod 101. Several conical holes 201 are opened on the surface of the shoe cover 2. Several first nylon bolts 104 are installed between the conical holes 201 and the connecting plate 103. The conical holes 201 facilitate the installation of bolts 104 and the top does not protrude, ensuring the comfort of the insole 3 after installation. A rear pressure plate 102 is fixedly connected to the side wall of the connecting plate 103.

[0030] The connecting strap 4 includes a first connecting strap 401, a second connecting strap 402, and a swivel roller 403. The first connecting strap 401 is connected to one side of the shoe cover 2, and the second connecting strap 402 is connected to the other side of the shoe cover 2. The swivel roller 403 is installed at the end of the first connecting strap 401, and the second connecting strap 402 is connected to the swivel roller 403. A Velcro 402a is provided on the surface of the second connecting strap 402. The swivel roller 403 has a plurality of toothed protrusions 403a arranged around its periphery. A first stitch 402b is provided between the Velcro 402a and the connecting strap 4. Both the first connecting belt 401 and the second connecting belt 402 are made of high-strength polyester fiber woven fabric, with a width of 40 mm and a thickness of 3 mm. The fastening method combines the swivel roller 403 and the hook and loop fastener 402a, which has higher reliability and safety and is the most convenient to operate. The swivel roller 403 has toothed protrusions on its body. When the second connecting belt 402 is pulled tight, the friction on it is greater. When it is overlapped again, the front and back of the explosion-proof hook and loop fastener 402a can be locked together to stick firmly. The hook and loop fastener will not be pulled apart when the horizontal force is greater.

[0031] As attached Figure 1 As shown: The shoe cover 2 has positioning grooves 205 and perforations 206 on both sides. The positioning grooves 205 have several connecting holes 207. The inner wall of the positioning grooves 205 is connected to the pads 5. The first connecting strap 401 and the second connecting strap 402 both pass through the connecting holes 207, and one end of the first connecting strap 401 and the second connecting strap 402 is connected to the pads 5. Nylon expansion tubes 208 are installed between the first connecting strap 401 and the second connecting strap 402 and the pads 5. The nylon expansion tubes 208 pass through the connecting holes 207. The second connecting strap 402 is also equipped with a positioning sleeve 404 on its periphery. A second stitching line 402c is provided between the pads 5 and the connecting straps 4. The positioning sleeve 404 can limit one end of the tightened second connecting strap 402 to ensure that the second connecting strap 402 can be quickly inserted to achieve quick fixation after putting on the shoes.

[0032] The pad 5 includes a short pad 501 and a long pad 502. The short pad 501 is connected to the side near the second connecting strap 402, and the long pad 502 is connected to the side near the first connecting strap 401. Several nylon expansion tubes 208 are installed between the left side wall of the shoe cover and the long pad 502, and several nylon expansion tubes 208 are installed between the right side wall of the shoe cover and the short pad 501. The connection stability between the shoe cover 2 and the pad 5 is ensured by setting the nylon expansion tubes 208.

[0033] As attached Figure 3 As shown: The end of the shoe cover 2 is provided with an ankle connection part 203, and an ankle groove 204 is formed between the ankle connection part 203 and the shoe cover 2; the ankle groove 204 is a 50*120 mm oval hole, which ensures that the heel of the climber's shoe is stuck in it, thereby improving the connection between the heel of the climber's shoe and the shoe cover 2.

[0034] Both outer walls of the shoe cover 2 are connected to pads 5. The pads 5 are made of soft insulating thermoplastic polyurethane, abbreviated as TPU plastic. There is one pad 5 on each side of each shoe cover 1. The pad 502 on the side with the D-shaped roller 403 is 70*180 mm in size, and the pad 501 on the side with the strap is 70*100 mm in size. The pads are 3 mm thick. The pads 5 ensure the comfort of the instep of the personnel working on the pole for a long time.

[0035] As can be seen from the above, during use, workers do not need to remove their shoes; they can directly slip their feet, along with their shoes, into the shoe cover 2. The rigid insulating plate on the bottom of the shoe cover 2 increases the contact area with the feet, improving comfort. The foot buckle 1 is fixed to the conical hole 201 on the shoe cover 2 using the first nylon bolt 104 via the connecting rod 101 and the connecting plate 103, with the rear pressure plate 102 providing additional fixation, ensuring a tight connection between the foot buckle and the utility pole. The connecting straps 4 on both sides of the shoe cover 2 have a D-shaped roller 403 at the end of the first connecting strap 401 through which the second connecting strap 402 passes. When the second connecting strap 402 is tightened, the toothed protrusions 403a on the periphery of the D-shaped roller 403 increase friction, and then the shoe cover is further secured by overlapping and pasting with Velcro 402a.

[0036] The person climbing the pole can separate the protective pad 5 and the connecting strap 4, put their foot through, and then tighten the second connecting strap 402 with one hand.

[0037] Example 2: Based on Example 1, the surface of the pressure-resistant insole 3 is provided with several mounting holes 301, and the surface of the shoe cover 2 is also provided with several positioning holes 202. A second nylon bolt 302 is installed between the mounting holes 301 and the positioning holes 202.

[0038] As can be seen from the above, the insole 3 is connected to the positioning hole 202 on the surface of the shoe cover 2 by the second nylon bolt 302, thereby fixing the position of the insole 3.

[0039] The main body of this shoe cover is made of ABS synthetic plastic, which has high electrical insulation and toughness. Qualified safety helmets made of this material are widely praised. However, synthetic plastic is not steel, so care should be taken during use. If it is damaged by external force, it should be replaced in time. The normal service life shall be in accordance with the power industry standards or national standards.

[0040] There is a discharge gap in the fixing bolt; the shoe cover 2 is connected to the connecting plate 103 with M8*40 flat-head nylon bolts. The gap between the upper surface of the shoe cover 2 and the iron plate of the foot buckle 1 is 15 mm. This gap has an air gap and is prone to air breakdown; this is solved by adding an insole 3. The pressure-resistant insole 3 is made of ABS material and has a pressure resistance of close to 10 kV. The front end is located at the toe of the shoe cover 2 and the rear end is embedded in the heel.

[0041] Due to the limitations of synthetic plastics, the main body of the shoe cover 2 needs to be processed by steel mold injection extrusion molding. The smaller the quantity, the higher the price. Large-scale supply is an effective way to reduce the price.
