Description

Technical Field

[0001] The utility model relates to the technical field of power cords, in particular to a power cord with a heat dissipation protective cover. Background Art

[0002] The heat dissipation protection of the power cord is divided into two aspects. On the one hand, it means that the outer skin of the power cord can prevent the power cord core from overheating and being damaged. On the other hand, it means that the outer skin of the power cord can withstand the high temperature in the environment and will not be damaged by the high temperature in the environment.

[0003] However, the heat dissipation effect of each part of the power cord is the same, so when there is a high temperature area in the environment where the power cord is laid, the outer skin of the power cord cannot withstand the high temperature for a long time and is damaged. Therefore, it is necessary to improve the traditional power cord so that it can add a heat dissipation protective cover as needed, thereby improving the high temperature resistance of the power cord. Utility Model Content

[0004] The purpose of the utility model is to solve the above problem and to provide a power cord with a heat dissipation protective cover.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A power cord with a heat dissipation protective sleeve comprises a cord body, an elastic rubber sleeve is disposed on the cord body, a notch is formed on one side of the elastic rubber sleeve, a protrusion matched with the notch is fixed on the other end, and a limiting piece is provided on the elastic rubber sleeve to assist the protrusion to stably engage with the notch.

[0007] Preferably, the limiting member includes a round block, both sides of which are fixedly connected with screws, the screws are threadedly connected to the screw holes provided on the rotating sleeve, a connecting block is rotatably connected to the rotating sleeve, a clamping block is fixedly connected to the connecting block, and a clamping groove adapted to the clamping block is provided on the elastic rubber sleeve.

[0008] Preferably, two slots are respectively provided on both sides of the elastic rubber sleeve.

[0009] Preferably, the elastic rubber sleeve is provided with a plurality of notches distributed at equal intervals, and the number of the protrusions corresponds to the number of the notches.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] 1. In the present application, an elastic rubber sleeve is used to cover the part of the wire body that needs additional protection, and the protrusion is engaged with the notch, so that the elastic rubber sleeve can stably surround the wire body under the action of elastic force. Therefore, under high temperature in the environment, the high temperature will not directly act on the outer skin of the wire body, and the high temperature will act on the elastic rubber sleeve to protect the wire body, thereby effectively extending the life of the wire body.

[0012] 2. After the card block and the card slot are engaged, the sleeve can be rotated to make the two connecting blocks approach each other, causing the elastic rubber sleeve to be restricted. The elastic rubber sleeve can stably surround the wire body and protect the wire body. Even if the elastic rubber sleeve is subjected to external force, the protrusion and the notch cannot be separated. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0019] The utility model provides a technical solution, please refer to Figure 1-3 :

[0020] A power cord with a heat dissipation protective sleeve comprises a wire body 1, an elastic rubber sleeve 2 is provided on the outer sleeve of the wire body 1, a notch 3 is provided on one side of the elastic rubber sleeve 2, a convex block 4 adapted to the notch 3 is fixed on the other end, and a limiting member is provided on the elastic rubber sleeve 2 to assist the convex block 4 to stably engage with the notch 3. A plurality of notches 3 are evenly distributed on the elastic rubber sleeve 2, and the number of the convex blocks 4 corresponds to the number of the notches 3. Therefore, after the convex blocks 4 are engaged with the notches 3, the elastic rubber sleeve 2 stably surrounds the wire body 1, and the interior of the elastic rubber sleeve 2 is filled with magnesium hydroxide powder flame retardant material, so the elastic rubber sleeve 2 can remain intact in a high temperature environment, effectively protecting the wire body 1. Example

[0021] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the limiting member includes a round block 6, and screws 7 are fixedly connected on both sides of the round block 6. The screws 7 are connected to the screw holes 9 provided on the rotating sleeve 8 by threads. A connecting block 10 is rotatably connected to the rotating sleeve 8, and a clamping block 11 is fixedly connected to the connecting block 10. A clamping groove 5 adapted to the clamping block 11 is provided on the elastic rubber sleeve 2. Two clamping grooves 5 are respectively provided on both sides of the elastic rubber sleeve 2. When the two rotating sleeves 8 are rotating, the two connecting blocks 10 can be brought close to each other. After the clamping block 11 is engaged with the clamping groove 5, the elastic rubber sleeve 2 can be limited. At this time, the elastic rubber sleeve 2 will not be separated from the wire body 1 even if it is subjected to external force.

[0022] In summary, the area on the wire body 1 that needs additional protection is determined in this embodiment, and then the elastic rubber sleeve 2 can be moved so that the elastic rubber sleeve 2 is sleeved on the wire body 1, and the protrusion 4 is engaged with the notch 3. The rotating sleeves 8 on both sides of the round block 6 are rotated respectively, so that the two connecting blocks 10 are close to each other until the clamping block 11 extends into the clamping groove 5. At this time, the two connecting blocks 10 clamp the elastic rubber sleeve 2, and even if the elastic rubber sleeve 2 is subjected to external force, the protrusion 4 will not be separated from the notch 3, so the elastic rubber sleeve 2 can be firmly sleeved on the wire body 1, thereby playing a protective effect on the wire body 1.

[0023] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
