Background

The tested object is usually connected with the control device outside the box through the cable in the test box to reach the purposes such as power supply, communication, monitoring, control, current test equipment leaves the line hole usually on the box wall, is circular, for preventing to receive external environment influence, fills the line hole with cloth or billet etc. usually after crossing the line, and sealed effect is poor, and the cable is difficult fixed, and when especially the cable rocked, easily lead to the stuff to drop.

The cable requirements of different tested products are different, such as quantity, diameter size and the like, when different tests are carried out, the cable needs to be frequently replaced and fastened, an external tool is usually needed for assistance, the time consumption is long, and the test efficiency is greatly reduced.

Through the patent of retrieval authorization, among the similar device with cable sealing device as the main, the structure is complicated, and the use method is fixed, should not repeatedly dismouting, does not have the locking effect.

Disclosure of Invention

The utility model aims at solving the problem that the closed proof box crosses the line hole cable not hard up, the leakproofness is poor, provide a cross the sealed locking device of line, can realize that the proof box crosses the quick seal of line hole and cable fastening, supply various environmental test case to use.

The utility model provides a technical scheme that above-mentioned problem adopted: the wire passing sealing and locking device comprises a wire passing stud 1, a sealing ring I2, a sealing ring II3, a thin nut 4, a tapered split ring 5 and a wire passing cover type nut 6; the wire-passing stud 1 sequentially passes through the sealing ring I2, the box wall 8, the sealing ring II3 and the thin nut 4, and the thin nut 4 is in threaded connection with the wire-passing stud 1; the conical split ring 5 is attached to and placed in an inner groove of the wire passing stud 1, the cable 7 sequentially penetrates through the wire passing stud 1, the conical split ring 5 and the wire passing cover type nut 6, and the wire passing cover type nut 6 is in threaded connection with the wire passing stud 1 through knurled patterns.

The utility model discloses a toper split ring 5 is by copper, nylon or tetrafluoroethylene, and internal diameter and opening size receive external force variable, more do benefit to the cable and closely laminate with the device, and sealed and locking effect is better.

The utility model discloses a 5 front ends of toper split rings are the taper shape, and the rear end is cylindrically. The structural design mainly aims at larger stress and tighter compression in the compression process.

The utility model discloses a cross 1 one end recess of line double-screw bolt and be the taper shape. Such a design is primarily a structural adaptation to the tapered split ring 5.

The utility model has the advantages that: the utility model has simple structure, few parts and can be quickly installed and dismantled; the cable 7 is compressed by closing the conical split ring 5 to prevent the cable from loosening; the tightening of the wire passing cover type nut 6 and the close fitting of the conical split ring 5 and the groove inner conical surface of the wire passing stud 1 play a role in sealing the test box. The test shows that the sealing effect is 100%. Therefore, the utility model discloses effectively solved the locking and the sealed problem of proof box of airtight proof box and external equipment connection cable.

Detailed Description

The technical solution of the present invention will be further clearly and completely described below with reference to the accompanying drawings and embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Example 1

Fig. 1 is a schematic view of an embodiment of the wire passing sealing and locking device of the present invention.

In the figure, the thread-passing stud 1, the thin nut 4 and the thread-passing cover type nut 6 are made of copper, the sealing ring I2 and the sealing ring II3 are made of silicon rubber, and the tapered split ring 5 is made of tetrafluoroethylene.

Supposing that a tested product in the closed test box is connected with the control instrument outside the box through a cable, the cable needs to be sealed and locked through 8 holes on the box wall, the test condition in the box is prevented from being influenced by the external environment, the hole part of the box wall 8 is provided with the device, the device is processed into the wire passing stud 1, the sealing ring I2, the sealing ring II3, the thin nut 4, the conical split ring 5 and the wire passing cover type nut 6 through tolerance fit calculation according to the diameter size of the 8 holes on the box wall, wherein the conical surface angle after the conical split ring 5 is compressed (the opening is closed) is not less than the angle of the inner conical surface of the groove of the; the sizes of the wire through stud 1, the conical split ring 5 and the wire through cover type nut 6 are matched with the diameter size tolerance of the cable 7.

As shown in fig. 1, the threading stud 1 sequentially passes through a sealing ring I2, a box wall 8 and a sealing ring II3, and a thin nut 4 is tightly attached to the sealing ring II3 and is in threaded connection and fastening with the threading stud 1; the conical split ring 5 is placed along the groove conical surface of the wire stud 1; the cable 7 sequentially passes through the wire-passing stud 1, the conical split ring 5 and the wire-passing cover-shaped nut 6, the wire-passing cover-shaped nut 6 is in threaded connection with the wire-passing stud 1, the wire-passing cover-shaped nut 6 is manually screwed down, the conical split ring 5 is pushed in, the opening of the wire-passing cover-shaped nut is reduced, the inner aperture of the wire-passing cover-shaped nut is reduced, and the cable 7 is locked and is not loosened.

The embodiment achieves the following effects: the device can be quickly installed, the cable is fastened, and the cable is prevented from loosening and influencing the test; the opening of the box wall 8 of the test box has a sealing effect, and the test condition of a tested object in the test box is prevented from being influenced by the external environment, so that the test result is inaccurate.
