[0007] To achieve the above purpose, the utility model provides the following technical scheme: A rubber waterproof sleeve for electric wires, including a waterproof sleeve. The waterproof sleeve includes a fixing ring, a first rubber ring, a second rubber ring and a connecting band. A threaded ring is fixedly arranged on the inner side wall of the fixing ring. The first rubber ring is fixedly connected to the fixing ring. The connecting band is fixedly connected to the first rubber ring. The second rubber ring is fixedly connected to the connecting band. An elastic ring is fixedly arranged on the second rubber ring, and one end of the elastic ring is located in the second rubber ring.

[0008] Preferably, an anti-slip ring is fixedly arranged on the fixing ring.

[0009] Preferably, the connecting band is made of rubber material, and the hardness of the first rubber ring is greater than that of the connecting band.

[0010] Preferably, the diameter of the first rubber ring is greater than that of the second rubber ring.

[0011] Preferably, the threaded ring is made of insulating material.

[0012] Preferably, the elastic ring is in the shape of being narrow at the top and wide at the bottom, and the narrow end of the opening of the elastic ring faces away from the first rubber ring.

[0013] In summary, the present application has the following beneficial technical effects: When in use, one end of the wire is inserted into the elastic ring of the waterproof sleeve, so that the narrow end of the elastic ring abuts against the connecting wire, and then the fixing ring 6 is screwed onto the connector through the threaded ring 7. At this time, the connection between the connector and the connecting wire is protected in the waterproof sleeve, and the connection between the connecting wire and the connector is not easily damaged by water. Also, due to the shape of the waterproof sleeve, water is not likely to accumulate at the waterproof sleeve, and the connection is better protected, achieving the effect of improving the waterproof property of the connection between the wire connector and the connecting wire.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0021] The following will further describe the present application in detail Figures 1-3 with reference to the attached drawings.

[0022] A rubber waterproof sleeve for wires includes a waterproof sleeve, and the waterproof sleeve includes a fixing ring 6, a first rubber ring 4, a second rubber ring 2, and a connecting band 3. A threaded ring 7 is fixedly arranged on the inner side wall of the fixing ring 6, which facilitates the installation of the fixing ring 6 on the connector of the wire through the threaded ring 7.

[0023] The first rubber ring 4 is fixedly connected to one end of the fixed ring 6. The connecting belt 3 is fixedly connected to the first rubber ring 4. The second rubber ring 2 is fixedly connected to the connecting belt 3. The connecting belt 3 is located between the first rubber ring 4 and the second rubber ring 2. The connecting belt 3 is made of rubber material. The hardness of the first rubber ring 4 is greater than that of the connecting belt 3, so that the first rubber ring 4 and the second rubber ring 2 can be telescopically arranged, which is convenient for wrapping the joint of the wire and the connection part of the connecting wire.

[0024] An elastic ring 1 is fixedly arranged on the second rubber ring 2. One end of the elastic ring 1 is located in the second rubber ring 2. The elastic ring 1 has elasticity. The end of the elastic ring 1 located in the second rubber ring 2 can better protect the connecting wire in the waterproof sleeve, so that the connecting wire in the waterproof sleeve is not easily damaged due to excessive folding.

[0025] The elastic ring 1 is in the shape of being narrow at the top and wide at the bottom. The narrow end of the opening of the elastic ring 1 faces away from the first rubber ring 4. When the waterproof sleeve is installed on the wire, the narrow side of the opening of the elastic ring 1 abuts against the connecting wire of the wire, so that water is not easily permeated into the waterproof sleeve from the connection part between the elastic ring 1 and the connecting wire.

[0026] The diameter of the first rubber ring 4 is greater than that of the second rubber ring 2, so that the whole waterproof sleeve is in the shape of a funnel, which is convenient for the drainage of accumulated water and not easy to accumulate on the waterproof sleeve. The threaded ring 7 is made of rubber material, which improves the safe use of the waterproof sleeve.

[0027] The implementation principle of this embodiment is as follows: When in use, one end of the wire is inserted into the elastic ring 1 of the waterproof sleeve, so that the narrow end of the elastic ring 1 abuts against the connecting wire. Then, the fixed ring 6 is threadedly connected to the connector through the threaded ring 7. At this time, the connection part between the connector and the connecting wire is protected in the waterproof sleeve. The connection part between the connecting wire and the connector is not easily damaged by water. Also, because the whole waterproof sleeve is in the shape of a funnel, water is not easily accumulated at the waterproof sleeve, and the connection part is better protected, achieving the effect of improving the waterproof property of the connection part between the wire connector and the connecting wire.
