Abstract

This utility model discloses a safety protection device for outdoor power construction, including a fixing mechanism. A connecting rope is installed on one side of the fixing mechanism, and an installation groove is fixedly connected to the end of the connecting rope away from the fixing mechanism. In the above scheme, pulling the sleeve stretches the return spring, causing the friction pad to move away from the installation groove. After the sleeve and gear can rotate the knob to fix the collar, the return spring pulls the sleeve to squeeze the knob, and the friction pad squeezes the installation groove, increasing the friction between the friction pad and the installation groove, thus restricting the rotation of the knob. Compared with the original device, the knob is protected by additional measures, preventing accidental unlocking of the collar due to accidental contact with the knob or the collar rotating in the opposite direction, thus avoiding safety hazards and improving the protective effect of the device. Pulling the sleeve, after the first slide groove and the second slide groove are aligned, push the slider to squeeze the wider side of the slider into the first slide groove for temporary limitation, allowing the knob to rotate freely, thus improving the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of power construction auxiliary components technology, and more specifically, to a safety protection device for outdoor power construction. Background Technology

[0002] During outdoor power construction, workers need to climb utility poles to inspect circuits at heights. Safety devices are required to protect workers during the inspection process. Traditional outdoor power construction safety devices are complex to connect during the climb, which can hinder workers' movement.

[0003] To address the aforementioned issues, patent document publication number CN219595678U discloses a safety device for outdoor power construction, comprising a waist guard ring, a collar structure, and an adjustment structure, all equipped with a crotch cover. The crotch cover has adjustment straps installed at both the front and rear ends, and two first shoulder straps are installed on one side of the top of the waist guard ring.

[0004] However, in actual use, it still has some drawbacks. For example, while the friction between the collar and the utility pole slows down the falling speed of the worker until it stops, preventing injury from a fall, the structure allows for a convenient connection between the device and the utility pole, ensuring worker safety without hindering their movement. However, when the device drives the bidirectional screw to rotate via a knob, there are no other safety measures. During climbing, there is a high possibility of accidentally touching the knob or causing the collar to rotate in the opposite direction, resulting in the collar being accidentally unlocked, losing its protective function, and creating a safety hazard. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a safety protection device for outdoor power construction, so as to solve the problem that the existing ring is easy to be accidentally unlocked, which brings safety hazards.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a safety device for outdoor power construction, including a fixing mechanism, a connecting rope installed on one side of the fixing mechanism, and an installation groove fixedly connected to the end of the connecting rope away from the fixing mechanism; the safety device for outdoor power construction also includes...

[0007] A knob, which is rotatably connected to one side of the mounting slot, and a gear is fixedly connected to the surface of the knob;

[0008] A sleeve is slidably connected to the surface of a gear. An internal tooth groove is provided inside the sleeve, and the inner side of the internal tooth groove is slidably connected to the outer edge of the gear. A spring groove is provided inside the sleeve, and a return spring is provided inside the spring groove. One end of the return spring is fixedly connected to the inner wall on the right side of the sleeve, and the other end of the return spring is fixedly connected to the side of the knob away from the mounting groove.

[0009] A friction pad is fixedly connected to the side of the sleeve near the mounting groove, and one side of the friction pad is in contact with one side of the mounting groove.

[0010] The safety device for outdoor power construction also includes a temporary limiting component, which is installed inside the sleeve.

[0011] The temporary limiting component includes a first slide groove, a second slide groove, a slider, and a slot. The first slide groove is located inside the knob, the second slide groove is located inside the sleeve, the surface of the slider is slidably connected to the interior of the first slide groove, the surface of the slider is slidably connected to the interior of the second slide groove, and the slot is located on the left side of the slider, with the interior of the slot engaging with the inner wall of the first slide groove.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above solution, when the knob needs to be rotated, the sleeve is pulled back, causing the gear to slide in the internal tooth groove, stretching the return spring, and moving the friction pad away from the mounting groove. The knob can be rotated to fix the collar through the sleeve and the gear. After the collar is fixed, the sleeve is driven to squeeze the knob under the tension of the return spring, which in turn squeezes the mounting groove through the friction pad, increasing the friction between the friction pad and the mounting groove and restricting the rotation of the knob. Compared with the original device, the knob is protected by additional measures. The collar will not be accidentally unlocked due to accidental contact with the knob or the collar rotating in the opposite direction, thus avoiding safety hazards and improving the protection effect of the device.

[0014] Pull the sleeve until the first slide groove aligns with the second slide groove. Then push the slider to push the wider side of the slider into the first slide groove for temporary limiting. This allows the knob to rotate freely, improving the practicality of the device. Attached Figure Description

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 5 This utility model provides a safety device for outdoor power construction, including a fixing mechanism 1. A connecting rope 2 is installed on one side of the fixing mechanism 1, and an installation groove 3 is fixedly connected to the end of the connecting rope 2 away from the fixing mechanism 1. The safety device for outdoor power construction also includes...

[0024] Knob 4 is rotatably connected to one side of the mounting groove 3, and a gear 5 is fixedly connected to the surface of the knob 4;

[0025] Sleeve 6 is slidably connected to the surface of gear 5. The sleeve 6 has an internal tooth groove 7, the inner side of which is slidably connected to the outer edge of gear 5. The sleeve 6 also has a spring groove 8, which contains a return spring 9. One end of the return spring 9 is fixedly connected to the inner wall on the right side of the sleeve 6, and the other end is fixedly connected to the side of the knob 4 away from the mounting groove 3. Gear 5 meshes with the internal tooth groove 7 and can slide axially inside the internal tooth groove 7. The return spring 9 is always in a stretched state, maintaining tension on the sleeve 6 at all times.

[0026] Friction pad 10 is fixedly connected to the side of sleeve 6 near mounting groove 3. One side of friction pad 10 is in contact with one side of mounting groove 3. Under the pulling force of return spring 9, sleeve 6 squeezes friction pad 10 to increase friction with mounting groove 3 and prevents knob 4 from rotating by itself.

[0027] Among them, such as Figure 4The safety device for outdoor power construction also includes a temporary limiting component 11, which is installed inside the sleeve 6.

[0028] Among them, such as Figure 5 The temporary limiting component 11 includes a first slide groove 111, a second slide groove 112, a slider 113, and a retaining groove 114. The first slide groove 111 is located inside the knob 4, the second slide groove 112 is located inside the sleeve 6, the surface of the slider 113 is slidably connected to the interior of the first slide groove 111, and the surface of the slider 113 is slidably connected to the interior of the second slide groove 112. The retaining groove 114 is located on the left side of the slider 113, and the interior of the retaining groove 114 engages with the inner wall of the first slide groove 111. In the initial state, the sleeve 6 is pressed tightly against the mounting groove 3. At this time, the first slide groove 111 and the second slide groove 112 are misaligned. The second slide groove 112 is in contact with the wider part of the slider 113, and the first slide groove 111 is in contact with the narrower part in the middle of the slider 113. When the sleeve 6 is pulled, the first slide groove 111 and the second slide groove 112 can be aligned. The slider 113 can be slid to insert the wider part into the first slide groove 111, which serves as a temporary limit and relieves the friction of the friction pad 10. The knob 4 can be rotated freely through the sleeve 6.

[0029] The working process of this utility model is as follows: When it is necessary to rotate the knob 4, pull the sleeve 6 backward, drive the gear 5 to slide in the internal gear groove 7, stretch the return spring 9, and make the friction pad 10 away from the mounting groove 3. After the first slide groove 111 and the second slide groove 112 are aligned, push the slider 113, squeeze the wider side of the slider 113 into the first slide groove 111 for temporary limiting. The knob 4 can be freely rotated to fix the collar through the sleeve 6 and the gear 5. After fixing the collar, push the slider 113 to its original position. Under the pulling force of the return spring 9, drive the sleeve 6 to squeeze the knob 4, and then squeeze the mounting groove 3 through the friction pad 10, increasing the friction between the friction pad 10 and the mounting groove 3, and restricting the rotation of the knob 4.
