The sealing opening is clamped in the clamping groove; and a plugging material is filled in the outer plug. According to the device, the outer plug is matched with the inner plug, after the inner plug is screwed, the plugging material in the outer plug can be extruded by the inner plug and is outwards adhered between the outer plug and the cable tube from the through hole, and compared with plugging by independently using the plugging material, the structure is firmer, the plugging material does not make contact with the outside, and the plugging effect is better. And the plugging material is prevented from contacting with the outside to cause plugging material failure.

Description

Technical Field

[0001] The utility model relates to the field of cable blocking, in particular to a bracket used for cable blocking. Background Art

[0002] Cables play a vital role in power transmission and communication systems. In order to protect the cables and ensure the normal operation of the system, measures must be taken to prevent moisture, dust and other environmental factors from entering the cable duct. This requires the use of cable sealing brackets, which are specially designed to fix and seal the ends of cables.

[0003] The existing plugging brackets are usually sealed by using plugging materials to seal the ends of the cable tubes. However, when the plugging materials are simply used for sealing, the plugging materials are easily separated from the tube wall after hardening, which affects the sealing effect. Utility Model Content

[0004] The utility model is based on the above technical problems and proposes a bracket for cable blocking.

[0005] A bracket for cable sealing, comprising: an outer plug, an inner sleeve, and a seal, wherein the outer plug is a hollow tube, the outer diameter of the outer plug gradually increases from the back to the front, a ring edge is provided at the front end of the outer plug, an internal thread is provided at the front end of the outer plug, an external thread matching the internal thread is provided at the front of the inner sleeve, the inner sleeve is also a hollow tubular structure, a slot is provided at the front opening of the inner sleeve, and the seal is clamped in the slot; the outer plug is filled with sealing material.

[0006] Preferably, the inner sleeve is a hollow tube composed of two semicircles.

[0007] Preferably, the front end of the outer plug is provided with an annular groove, and the front end of the inner sleeve is provided with a side edge matching the annular groove.

[0008] Preferably, an array of through holes is opened on the side wall of the outer plug.

[0009] Beneficial effect: The device utilizes an outer plug in cooperation with an inner plug. After the inner plug is tightened, the sealing material in the outer plug will be squeezed out by the inner plug and adhere to the outer hole from the through hole to the outside between the outer plug and the cable pipe. Compared with sealing with sealing material alone, its structure is more solid, and the sealing material does not contact the outside world, thus avoiding the sealing material contacting the outside world and causing the sealing material to fail. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The structure of the utility model is shown Figure 1 ;

[0011] Figure 2 The structure of the utility model is shown Figure 2 . DETAILED DESCRIPTION

[0012] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0013] like Figure 1~Figure 2 A bracket for cable sealing is shown, comprising: an outer plug 1, an inner sleeve 3, and a seal 6. The outer plug 1 is a hollow tube, and an array of through holes 8 are opened on the side wall of the outer plug 1. An annular groove 9 is provided at the front end of the outer plug 1. The outer diameter of the outer plug 1 gradually increases from the back to the front. A ring edge 2 is provided at the front end of the outer plug 1. The diameter of the ring edge 2 is larger than the diameter of the cable tube. An internal thread is provided at the front end of the outer plug 1, and an external thread 4 matching the internal thread is provided at the front part of the inner sleeve 3. The inner sleeve 3 is a hollow tube composed of two semicircles. The front end of the inner sleeve 3 is provided with a side edge 5 matching the annular groove 9, and a slot 7 is provided at the front opening of the inner sleeve 3. The seal 6 is stuck in the slot 7; the outer plug 1 is filled with sealing material.

[0014] The installation process of this device is:

[0015] First, insert the end of the cable into the outer plug 1, and install the outer plug 1 to the pipe mouth of the cable pipe. During installation, use a hammer or other tools to knock the outer plug 1 into the cable pipe, because the outer diameter of the outer plug 1 is smaller at the front and larger at the back, and the outer diameter of the rear part of the outer plug 1 is slightly larger than the outer diameter of the cable pipe when designed; after the outer plug 1 is installed, use the two semicircular structures of the inner sleeve 3 to clamp the cable, and the two semicircular structures are fixed by snap connection. After the connection is completed, fill the rear opening 10 of the outer plug 1 with hard material, and then fill the outer plug 1 with sealing material. The sealing material filling should exceed half of the height of the outer plug 1, and then insert the inner sleeve 3 into the outer plug 1 and tighten it. During the tightening process of the inner sleeve 3, the sealing material will be squeezed from the through hole 8 into the space between the outer plug 1 and the cable pipe, making the sealing of the cable pipe tighter, and finally the seal 6 is clamped at the opening at the front end of the inner sleeve 3.

[0016] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
