Description

Technical Field

[0001] This utility model relates to the field of foot spike technology, specifically a high-stability foot spike. Background Technology

[0002] Currently, during the installation and maintenance of power transmission towers and telecommunications signal receiving towers, the protective foot spikes typically used by workers are steel rods with an obtuse angle of 145 degrees. One end of the steel rod is fixed to the tower, and the other end stands upright at an obtuse angle of 145 degrees. When climbing the tower, workers attach the safety harness around their waist to the steel rod and use their hands to grab the protective foot spikes to climb. Since the safety harness is directly attached to the steel rod in an open space, there is a risk that the safety harness may slip off the steel rod during the operation, which could compromise the personal safety of the workers. Therefore, there is an urgent need to develop a new, stable, and safe foot spike. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-stability foot spike, comprising a foot spike body, one end of which is threaded and the other end is bent upwards. A vertical rod is fixedly installed at the lower end of the foot spike body, and a horizontal rod is detachably installed at the bottom of the vertical rod. A sliding sleeve is slidably fitted on the outer side of the horizontal rod, and a sliding rod is fixedly installed inside the sliding sleeve. A sliding hole for inserting the sliding rod is opened in the horizontal rod, and the sliding rod is connected to the bottom of the sliding hole by a spring. A stop bar is fixedly installed at the end of the sliding sleeve away from the vertical rod. A closed rectangular placement cavity is formed between the foot spike body, the vertical rod, the sliding rod, and the stop bar. The rectangular placement cavity is used to place a safety rope buckle. When the sliding sleeve slides to the right, an opening is formed between the stop bar and the foot spike body.

[0005] Preferably, a stud is fixedly installed at one end of the crossbar, and a through hole is provided at the bottom of the vertical bar for the stud to pass through, and a lock nut is screwed onto the stud.

[0018] Please see Figure 1-2This utility model provides a technical solution: a high-stability foot spike, including a foot spike body 1, one end of which is threaded 2 and the other end is bent upward. A vertical rod 3 is fixedly installed at the lower end of the foot spike body 1, and a horizontal rod 4 is detachably installed at the bottom of the vertical rod 3. A sliding sleeve 5 is slidably fitted on the outside of the horizontal rod 4, and a sliding rod 6 is fixedly installed inside the sliding sleeve 5. A sliding hole 7 for the sliding rod 6 to be inserted is opened inside the horizontal rod 4. The sliding rod 6 is connected to the bottom of the sliding hole 7 by a spring 8. A stop bar 9 is fixedly installed at the end of the sliding sleeve 5 away from the vertical rod 3. A closed rectangular placement cavity is formed between the foot spike body 1, the vertical rod 3, the sliding rod 6, and the stop bar 9. The rectangular placement cavity is used to place a safety rope buckle. When the sliding sleeve 5 slides to the right, an opening is formed between the stop bar 9 and the foot spike body 1.

[0019] By adopting the above technical solution, the foot nail body 1 is provided with a thread 2 on one side to facilitate connection with the iron tower. The foot nail body 1, the vertical rod 3, the sliding rod 6 and the stop bar 9 form a closed rectangular placement cavity that can be used to place the safety rope lock, thereby improving safety. The design of the sliding sleeve 5 and the spring 8 allows the stop bar 9 to be opened when needed, making it convenient to put in and take out the lock.

[0020] In this embodiment, the crossbar 4 is further configured to have a stud 10 fixedly installed at one end, the bottom of the vertical bar 3 is provided with a through hole for the stud 10 to pass through, and a locking nut is screwed onto the stud 10.

[0021] By adopting the above technical solution, through the design of stud 10 and locking nut, the crossbar 4 can be firmly installed at the bottom of the vertical bar 3, and is easy to disassemble, facilitating the replacement of subsequent parts.

[0022] In this embodiment, the vertical rod 3 is provided with a pair of positioning grooves at its bottom, and the horizontal rod 4 is fixed with a pair of positioning blocks 12 that can be inserted into the positioning grooves at one end.

[0023] By adopting the above technical solution, the design of positioning block 12 and positioning groove ensures the correct position of crossbar 4 at the bottom of vertical bar 3, enhancing the stability of the connection.

[0024] In this embodiment, the surface of the foot nail body 1 is provided with anti-slip texture.

[0025] By adopting the above technical solution, the anti-slip texture design increases the friction coefficient of the foot spike body 1, improves the friction of the foot spike during use, and enhances stability.

During use, when stepping on the foot nail body 1, the upward bending end of the foot nail body 1 can prevent the foot from sliding to the outside of the foot nail body 1, thus preventing the foot from slipping. Then pull the sliding sleeve 5 to the right, so that it drives the stop bar 9 to move synchronously. An opening is formed between the stop bar 9 and the foot nail body 1. At this time, the safety lock or lock head of the safety rope can be fitted onto the sliding sleeve 5 through the opening. When the sliding sleeve 5 is released, the spring 8 drives the sliding rod 6 to return to the left, and the stop bar 9 moves to the left and contacts the foot nail body 1, thus forming a closed space to prevent the lock head from slipping off. It is convenient to use.
