detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figure 1, it is an embodiment of the present utility model, a kind of anti-leakage protective device, comprises rod member 1 and outer sleeve 2 with circular platform cylindrical head 3, outer sleeve 2 is the insulating plastic tube with elasticity, belt The round table cylindrical head 3 of the rod part 1 of the round table cylindrical head 3 can be inserted into the outer sleeve 2 to open the outer sleeve 2, and when the rod 1 with the round table cylindrical head 3 is pulled out, the outer sleeve 2 can be inserted into the round table The bare wire core in the cylindrical head 3 is wrapped tightly.

In this embodiment, the cylindrical head 3 is used to stretch the elastic outer sleeve 2 , and the exposed wire core to be protected is placed in the cylindrical head 3 . Then, the cylindrical head 3 of the cone is moved to the opposite direction of the exposed wire core through the rod 1, while keeping the relative position of the outer sleeve 2 and the exposed wire core unchanged. Before the rod 1 moves, the outer sleeve 2 wraps the cylindrical head 3 on the outside of the cylindrical head 3 , and the exposed wire core is placed inside the cylindrical head 3 . After the rod member 1 moves, it is equivalent to pulling out the cylindrical head 3 of the cone 3 from between the outer sleeve 2 and the exposed wire core, so that the outer sleeve 2 wraps the exposed wire core. Since the outer sleeve 2 is an elastic insulating plastic tube, the outer sleeve 2 can completely wrap the exposed wire cores to avoid contact with the outside world and achieve the purpose of leakage protection. In addition, if the exposed wire core needs to be reprocessed, the rod 1 can be pushed in the direction of the exposed wire core, so that the cylindrical head 3 of the cone can expand the outer casing 2 again. The rod 1 with the cylindrical head 3 and the outer sleeve 2 are removed, and then the exposed wire core can be inspected, connected and other treatments can be performed.

The utility model can ensure that the staff does not directly contact the detected wire core during the operation process, thereby avoiding the risk of electric shock. The utility model has stable structure, convenient operation, and is convenient to be used in various construction environments, and has the characteristics of convenient use, no electric leakage, and portability.

Preferably, the cylindrical head 3 is cylinder-shaped, and from the open end of the cylindrical head 3 to the closed end of the cylindrical head 3, the diameter of the cylindrical head 3 gradually gradually increases. increase and then gradually decrease.

Wherein, the cylindrical head 3 of the circular platform is set in a cylinder shape with relatively small diameters at both ends and a relatively large diameter in the middle, so that the relative position of the cylindrical head 3 and the outer sleeve 2 is not easy to slide. Prevent the device from falling off automatically during the carrying process and other non-staff operations, making it unusable. And the exposed wire core can be conveniently placed inside the cylindrical head 3 during use. It also makes the inside of the cylindrical head 3 of the circular platform accommodate longer exposed wire cores, and when the exposed wire cores are longer, the device can also perform good leakage protection.

Preferably, the diameter of the open end of the cylindrical head 3 is greater than or equal to 8 mm. Make the open end of the cylindrical head 3 of the round table can put into the electric wire core of general national standard. For other more special wire cores with a thicker diameter, the corresponding cylindrical head 3 of the circular platform can be manufactured specially, so that the diameter of the opening end of the cylindrical head 3 of the circular platform can be greater than the diameter of the exposed wire core to be protected.

Preferably, the angle a formed between the inclined plane from the opening end of the cylindrical head 3 to the maximum diameter of the cylindrical head 3 and the axial direction of the cylindrical head 3 is Less than or equal to 45 degrees.

Wherein, the slope angle from the opening end of the cylindrical head 3 to the maximum diameter of the cylindrical head 3 will affect the relative movement between the cylindrical head 3 and the outer sleeve 2 . Because when the cylindrical head 3 of the circular platform pushes towards the exposed wire core, the large angle will make the cylindrical head 3 of the circular platform unable to stretch the outer sleeve 2, resulting in the device being unusable. Therefore, the design of this slope and the axial direction of the cylindrical head 3 The included angle a is less than or equal to 45 degrees.

Preferably, the rod 1 with the cylindrical head 3 is provided with an insulating layer. Although the cylindrical head 3 of the circular platform is made of insulating material, in order to further strengthen the insulation protection, an insulation layer is added to the outside of the rod 1 to strengthen the protection of the staff.

Preferably, the insulating layer is made of rubber.

The utility model can ensure that the staff does not directly contact the detected wire core during the operation process, thereby avoiding the risk of electric shock. The utility model has stable structure, convenient operation, and is convenient to be used in various construction environments, and has the characteristics of convenient use, no electric leakage, and portability.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
