Description

Technical Field

[0001] The utility model belongs to the technical field of electric power construction, and in particular relates to an electric power insulating ladder. Background Art

[0002] An insulating ladder usually refers to a special ladder used in the power industry or in a working environment where electric shock prevention is required. This ladder has steps and handrails made of insulating materials to prevent electric current from being conducted to workers through the ladder and causing electric shock accidents. Insulating ladders are usually used in situations where work needs to be performed in high-risk environments such as near power equipment or high-voltage lines to ensure the safety of workers. The most commonly used insulating ladder is a single ladder, which is light and easy to move. When using a single ladder, the single ladder needs to be tilted. In order to keep the single ladder stable, an anti-skid pad is provided at the bottom of the single ladder to prevent the bottom of the insulating ladder from sliding and tipping over. However, due to the different inclination angles when the insulating ladder is placed, the anti-skid pad and the ground are also prone to have different inclination angles, and it is difficult for the anti-skid pad to fully contact the ground. In addition, during use, the movement of people will cause the insulating ladder to shake. During the shaking process, since the anti-skid pad is fixed to the ladder, the anti-skid pad will move with the shaking of the ladder and change the contact position with the ground, which will affect the stability of the ladder. Utility Model Content

[0003] The utility model provides an electric insulating ladder, which is connected by a connecting block and a connecting groove, thereby avoiding the situation in which the stability of the insulating ladder is affected due to a mismatch between the inclination angle of the insulating support rod and the angle of the bottom anti-skid pad or the shaking of the insulating support rod during use, which makes the contact area between the bottom anti-skid pad and the ground smaller or the contact position changes, thereby improving the stability of the insulating ladder when in use.

[0004] The utility model provides the following technical solution: it includes two insulating support rods, which are characterized in that: the inner sides of the two insulating support rods are connected by a plurality of insulating cross bars, the bottom of the insulating support rod is provided with an anti-slip base, the anti-slip base includes a bottom plate and a connecting seat, the connecting seat is fixedly connected to the top of the bottom plate, the bottom of the bottom plate is provided with a plurality of empty grooves, the inside of the empty grooves is provided with springs, the bottom of the springs is provided with anti-slip strips, the bottom of the insulating support rod is fixedly connected with a connecting block, the top of the connecting seat is provided with a connecting groove, and the connecting block is movably connected to the inner side of the connecting groove.

[0005] Wherein, the two anti-slip bases are connected by a connecting rod, and the connecting rod is parallel to a plurality of the insulating cross bars.

[0006] Wherein, the size of the connecting groove matches that of the connecting block, and a connecting shaft is provided on the inner side of the connecting groove.

[0007] Wherein, a through slot is provided on the connection block, and the connecting shaft is located at the inner side of the through slot.

[0008] Wherein, the length of the anti-slip strip is the same as the depth of the empty groove, and the anti-slip strip is slidably connected to the inner side of the empty groove.

[0009] The beneficial effects of the utility model are as follows: through the connection between the connecting block and the connecting groove, the angle between the insulating support rod and the connecting seat can be freely adjusted, which is beneficial to ensure that the bottom of the anti-skid base is always in close contact with the ground, avoiding the situation where the stability of the insulating ladder is affected due to the mismatch between the inclination angle of the insulating support rod and the angle of the bottom anti-skid pad or the shaking of the insulating support rod during use, which makes the contact area between the bottom anti-skid pad and the ground smaller or the contact position changes, thereby improving the stability of the insulating ladder when in use. At the same time, through the spring and the anti-skid strip, the insulating ladder can maintain a stable state on an uneven or relatively loose ground, reducing the influence of the ground on the insulating ladder.

[0010] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] See also Figure 1-Figure 4The utility model provides the following technical solution: it includes two insulating support rods 1, which are characterized in that: the inner sides of the two insulating support rods 1 are connected by a plurality of insulating cross bars 11, and a non-slip base 2 is provided at the bottom of the insulating support rod 1, and the non-slip base 2 includes a bottom plate 21 and a connecting seat 22, and the connecting seat 22 is fixedly connected to the top of the bottom plate 21, and a plurality of empty grooves 211 are provided at the bottom of the bottom plate 21, and a spring 212 is provided inside the empty groove 211, and an anti-slip strip 213 is provided at the bottom of the spring 212, and a connecting block 12 is fixedly connected to the bottom of the insulating support rod 1, and a connecting groove 221 is provided at the top of the connecting seat 22, and the connecting block 12 is movably connected to the inner side of the connecting groove 221.

[0017] In this embodiment, two insulating support rods 1 are included, and the two insulating support rods 1 have the same size. The inner sides of the two insulating support rods 1 are connected by a plurality of insulating cross bars 11. The two ends of the plurality of insulating cross bars 11 are respectively fixedly connected to the inner sides of the two insulating support rods 1, and the plurality of insulating cross bars 11 are parallel to each other. When in use, the insulating cross bars 11 and the insulating support rods 1 are used to support the user so that the user can climb upward. The bottom of the insulating support rods 1 is provided with an anti-slip base 2. When in use, by making the anti-slip base 2 contact with the ground, the probability of the insulating ladder tipping over can be reduced, and the stability of the insulating ladder when in use can be improved. The anti-slip base 2 includes a bottom plate 21 and a connecting seat 22. The connecting seat 22 is fixedly connected to the top of the bottom plate 21. The bottom plate 21 is mainly The bottom of the bottom plate 21 is provided with a plurality of empty slots 211, which are equidistantly distributed, and the bottoms of the plurality of empty slots 211 are in an open state. A spring 212 is provided inside the empty slot 211, and one end of the spring 212 is fixedly connected to the top of the empty slot 211. An anti-slip strip 213 is provided at the bottom of the spring 212, and the bottom of the spring 212 is fixedly connected to the top of the anti-slip strip 213. The anti-slip strip 213 can be pushed downward by the elastic force of the spring 212. When the bottom plate 21 is located on the ground, the bottoms of the plurality of anti-slip strips 213 will contact the ground. The contact between the plurality of anti-slip strips 213 and the ground can achieve the purpose of increasing the friction between the insulating ladder and the ground. When the ground is uneven, the elastic force of the spring 212 will push the anti-skid strip 213 located in the concave part downward to make it contact with the ground. If the bottom plate 21 is located on relatively loose land or sand, the thrust of the spring 212 will make several anti-skid strips 213 go deep into the ground, which is beneficial to improve the stability of the insulating ladder. The bottom of the insulating support rod 1 is fixedly connected with a connecting block 12, and the top of the connecting seat 22 is provided with a connecting groove 221. The connecting groove 221 matches the shape of the connecting block 12. The connecting block 12 is movably connected to the inner side of the connecting groove 221, and the outer side of the connecting block 12 is slidably connected to the inner side of the connecting groove 221. Through the connection between the connecting groove 221 and the connecting block 12, the connecting block 12 can be in the connecting groove 221. While rotating sideways, the connecting block 12 can be limited by the connecting groove 221 to prevent the connecting block 12 from separating from the connecting seat 22, so that the angle between the insulating support rod 1 and the connecting seat 22 can be freely adjusted, which is beneficial to ensure that the bottom of the anti-slip base 2 is always in close contact with the ground, avoiding the situation where the stability of the insulating ladder is affected due to the mismatch between the inclination angle of the insulating support rod 1 and the angle of the bottom anti-slip pad or the shaking of the insulating support rod 1 during use, which makes the contact area between the bottom anti-slip pad and the ground smaller or the contact position changes, thereby improving the stability of the insulating ladder when in use. At the same time, the spring 212 and the anti-slip strip 213 allow the insulating ladder to maintain a stable state on uneven or loose ground, reducing the impact of the ground on the insulating ladder.

[0018] The two anti-skid bases 2 are connected by a connecting rod 23, and the connecting rod 23 is parallel to the plurality of insulating cross bars 11; the two ends of the connecting rod 23 are respectively fixedly connected to the two anti-skid bases 2, and the distance and position between the two anti-skid bases 2 are fixed by the connection of the connecting rod 23.

[0019] The connecting groove 221 matches the size of the connecting block 12, and a connecting shaft 222 is provided on the inner side of the connecting groove 221; through the connection between the connecting groove 221 and the connecting block 12, the connecting block 12 can be rotated on the inner side of the connecting groove 221, and the connecting block 12 can be limited at the same time to prevent the connecting block 12 from separating from the connecting seat 22.

[0020] A through slot 121 is provided on the connecting block 12, and a connecting shaft 222 is located on the inner side of the through slot 121; through the connection between the through slot 121 and the connecting shaft 222, the connection between the connecting block 12 and the connecting seat 22 is further stabilized so that the connecting block 12 will not separate from the connecting seat 22 during the rotation process.

[0021] The length of the anti-slip strip 213 is the same as the depth of the slot 211 , and the anti-slip strip 213 is slidably connected to the inner side of the slot 211 ; since a spring 212 is provided inside the slot 211 , one end of the anti-slip strip 213 will be located outside the slot 211 .

[0022] The working principle and use process of the utility model are as follows: when in use, first place the anti-skid base 2 on the ground, and then place the insulating support rod 1 against a designated object to maintain a tilted state. During the tilting process of the insulating support rod 1, the connecting block 12 will rotate inside the connecting groove 221, so that the anti-skid base 2 can maintain full contact with the ground when the insulating support rod 1 is tilted. When a person climbs upward, the insulating support rod 1 will shake accordingly. The rotating connection between the connecting block 12 and the connecting seat 22 can prevent the shaking of the insulating support rod 1 from affecting the anti-skid base 2, which is beneficial to ensuring the stability of the insulating ladder.
