Description

Technical Field

[0001] The utility model relates to a novel composite wall bushing. Background Art

[0002] Wall bushings are widely used for transmitting current indoors and outdoors. For wall bushings with old structures or porcelain jacket structures, the umbrella sleeve is directly combined with the flange during assembly. During the assembly and adjustment process of the flange and the wall, the force of the wall reacting on the flange is transmitted to the umbrella sleeve, so the umbrella sleeve is easily damaged and difficult to repair. Summary of the Invention

[0003] The utility model provides a novel composite wall bushing in order to solve the problems existing in the above-mentioned prior art.

[0004] The technical solutions adopted in this utility model are:

[0005] A new type of composite wall bushing includes an insulating tube, a conductive rod, an umbrella skirt, an end gland, a locking nut, a flange and a protective sleeve. Two protective sleeves are arranged on the insulating tube at intervals. The flange is glued on the insulating tube and placed between the two protective sleeves. The two umbrella skirts are arranged on the insulating tube and placed on the outside of the two protective sleeves. The conductive rod is inserted into the insulating tube with both ends extending out of the insulating tube and passing through the two end glands. The locking nuts are threadedly connected to the two ends of the conductive rod and the end glands on both sides are pressed against the insulating tube.

[0006] Furthermore, mutually fitting step surfaces are provided between the umbrella skirt and the protective cover, and between the protective cover and the flange.

[0007] Furthermore, a step surface is provided on the outer wall of the insulating tube, and a protective sleeve abuts against the step surface.

[0008] Furthermore, a corrugated groove is provided on the joint surface between the flange and the insulating tube.

[0009] Furthermore, sealant is provided between each protective sleeve and the flange.

[0010] The utility model has the following beneficial effects:

[0011] The utility model can effectively avoid damage to the umbrella skirt, has a reasonable structural design, low manufacturing cost, good use effect, and the protective cover is easy to repair and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a structural diagram of the utility model.

[0013] Figure 2 It is a partial enlarged view of the utility model. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 and Figure 2 The utility model is a new type of composite wall bushing, including an insulating tube 1, a conductive rod 2, an umbrella skirt 3, an end gland 4, a locking nut 5, a flange 6 and a protective sleeve 7. The two protective sleeves 7 are sleeved on the insulating tube 1 at intervals, the flange 6 is glued on the insulating tube 1 and placed between the two protective sleeves 7, the two umbrella skirts 3 are sleeved on the insulating tube 1 and placed on the outside of the two protective sleeves 7, the conductive rod 2 is inserted into the insulating tube 1 and its two ends extend out of the insulating tube 1 and pass through the two end glands 4, the locking nuts 5 are threadedly connected to the two ends of the conductive rod 2 and the end glands 4 on both sides are pressed against the insulating tube 1.

[0016] During the assembly process of the flange 6 and the wall 8, since the flange 6 and the umbrella skirt 3 are provided with a protective cover, the force acting on the flange 6 is buffered by the protective cover and will not cause damage to the umbrella skirt. When the protective cover is damaged, it can be repaired by heating it with a heating repair mold. The outer wall surface of the protective cover is a smooth round surface, which is convenient for repair.

[0017] In order to ensure the positioning effect, mutually matching step surfaces are provided between the umbrella skirt 3 and the protective cover 7, and between the protective cover 7 and the flange 6, and sealant is applied to the corresponding joints to ensure sealing.

[0018] The outer wall of the insulating tube 1 is provided with a step surface 11, on which one of the protective sleeves 7 abuts. The step surface 11 on the outer wall of the insulating tube 1 can facilitate the rapid positioning of the protective sleeves 7. After one of the protective sleeves is quickly positioned, the other mounting parts can also be quickly positioned.

[0019] A corrugated groove is provided on the joint surface between the flange 6 and the insulating tube 1 , and the corrugated groove increases the application area of the adhesive.

[0020] The utility model can effectively avoid damage to the umbrella skirt, has a reasonable structural design, low manufacturing cost, good use effect, and the protective cover is easy to repair and easy to use.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
