The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a new type of power cord of the utility model comprises a power cord 1 and a plurality of support frames 3, wherein an axial protrusion is formed on the bottom surface of the power cord 1 to form a support portion 2, and the plurality of support frames 3 are all sleeved on the outside of the power cord 1, and a clamping block 4 for clamping and fixing the support frame 3 on the power cord 1 is arranged on the left and right in the opening at the lower end of the support frame 3, and a locking claw 5 is arranged inside the support frame 3, and a circular groove 7 is arranged on the top surface of the support frame 3, and an adjustment mechanism for driving the locking claw 5 to move up and down is installed in the circular groove 7.

[0021] In this embodiment, the opposite surfaces of the clamping block 4 are in contact with the side surfaces of the support portion 2, and the clamping block 4 is provided with an arc-shaped extrusion portion 11, the inner side surface of the extrusion portion 11 is in contact with the outer ring surface of the power cord 1, and the opposite end surfaces of the clamping block 4 are protruded to form a positioning portion 9, which extends to the inner side surface of the support frame 3. The contact area between the clamping block and the support frame is increased through the positioning portion, which can better ensure the stability of the clamping block.

[0022] In this embodiment, a retreat space is formed between the opposite end faces of the clamping block 4 and the open end faces of the support frame 3. A plurality of positioning holes are provided on the open end faces of the support frame 3. Positioning rods are provided in the positioning holes. One end of the positioning rods extends to the outside and is installed on the clamping block 4. A compression spring 10 is sleeved on the outside of the positioning rod. One end of the compression spring 10 is installed on the clamping block 4, and the other end is installed on the support frame 3. The clamping block is positioned by the positioning rod so that the clamping block can only move laterally along the positioning hole, thereby avoiding misalignment and falling.

[0023] In this embodiment, the locking jaws 5 are all arranged in a "C"-shaped structure, so that the locking jaws can contact the power line more comprehensively.

[0024] In this embodiment, the adjustment mechanism includes a screw, a rotating handwheel 6 and a bearing. A mounting portion 8 is protruded on the top surface of the locking clamp 5. The bearings are embedded in the top surface of the mounting portion 8. A screw hole is provided at the center of the circular groove 7. The rotating handwheel 6 is arranged inside the circular groove 7. The screw is threadedly connected to the screw hole. One end of the screw extends to the inside of the circular groove 7 and is installed on the bottom surface of the rotating handwheel 6. The other end of the screw is installed in the inner ring of the bearing.

[0025] In this embodiment, a gap is formed between the bottom surface of the rotating handwheel 6 and the bottom surface of the circular groove 7 for the rotating handwheel 6 to move downward. The diameter of the rotating handwheel 6 is larger than the inner diameter of the circular groove 7, so that the outer ring of the rotating handwheel is exposed, making it convenient to hold and turn the rotating handwheel.

[0026] When in use, the support portion below the power cord contacts the bottom surface, and the protruding support portion prevents the power cord from being worn out by direct contact with the ground.

[0027] When the power cord needs to pass through a pedestrian passage, the clamping block can be pulled outward. After the clamping block is opened, the width between the clamping blocks is greater than the diameter of the power cord, so that the support frame can be directly sleeved on the outside of the power cord. After the clamping block is released, the clamping block can be pushed inward by the rebound of the compression spring, so that the opposite surface of the clamping block abuts against the support part, and the extrusion part abuts against the power cord, so that the support frame can be connected to the power cord;

[0028] The bottom surface of the support frame can be in contact with the ground, and in order to ensure the stability of the support frame, the rotating hand wheel can be turned, and the rotation of the rotating hand wheel drives the screw rod to move downward along the screw hole, and the movement of the screw rod synchronously drives the locking jaws, so that the support frame can be positioned by pressing the locking jaws on the power line;

[0029] The distance between the support frames is smaller than the width of the shoes, so that pedestrians can only step on the support frames when passing by, and the weight of the support frames can directly act on the ground, avoiding wear and damage to the power cord.

[0030] Among them, since the distance between the support frames can be adjusted, when there are other objects (such as chairs, tables, sofas, etc.) on the channel, they can move inward to the support frames and lock them through the locking claws, so that the support frames can be placed on the feet of the above objects to ensure the stability of the power cord and avoid pulling on the electrical appliances.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
