Description
Technical field
The utility model relates to the cable penetration pipe, particularly a kind of steel thin wall penetration pipe and accessory thereof.
Background technology
Existing cable line penetration pipe generally adopts galvanized iron spool and accessory galvanized iron articulation, straight joint, elbow and duroplasts sleeve, galvanized iron articulation, straight joint, elbow are enclosed within galvanized iron penetration pipe one end, and articulation, straight joint, elbow are fastened on the penetration pipe by ending tight screw, the articulation outer end is provided with external screw thread, connects with connectors such as terminal appliance equipment distribution control cabinet terminal boxes.During threading, insert a duroplasts sleeve, carry out the threading operation in galvanized iron penetration pipe outer end.Because the easy corrosion of iron pipe, need the top layer zinc-plated and increase pipe wall thickness (1.2-2.5mm) and prolong its anti-oxidant phase, cause this pipe heavy, the production cost height, the construction inconvenience, and also the anti-oxidant phase is also limited; When passing through cable, have only one to mould sleeve firmly and isolating thicker articulation and spool mouth of pipe threading temporarily, one-way operation, this is moulded sleeve firmly and can not fix, can only one-way operation, can not bidirectional operation, finish and mould sleeve behind the threading firmly and be shifted easily even lose, like this in construction or in the use later on because of the burr of the spool mouth of pipe or splice port all might cause in various degree damage to the insulating barrier of pipe inner cable line, reduced security reliability.The cable penetration pipe sealing of said structure is relatively poor, and the junction is non-watertight, if pipe can send naked light when occurring improper factor such as short circuit between the inner cable, and is difficult to control, exists potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of steel thin wall penetration pipe and accessory thereof, and it can be accomplished, and good airproof performance, easy construction, production cost are lower, cost performance reaches safe and reliable by force.
The technical solution that the utility model proposed is such: a kind of steel thin wall penetration pipe and accessory thereof, comprise at least one section penetration pipe, articulation, sheath, described penetration pipe is a steel thin wall penetration pipe, the 1st section tight-lipped soft sheath 2 of moulding of the 1st rabbet joint type that is with of penetration pipe 1 front end, described articulation is the steel thin wall articulation, soft sheath 2 and the 1st section steel thin wall penetration pipe 1 front port moulded of described the 1st rabbet joint type tightly is inserted in this articulation 3, described articulation outer end is provided with external screw thread, tightly is with the soft sheath 4 of moulding of the 2nd rabbet joint type at this external thread part.
Steel thin wall penetration pipe adopts the stainless steel thin-wall penetration pipe, and the stainless steel thin-wall articulation is adopted in the steel thin wall articulation.The wall thickness of described stainless steel thin-wall penetration pipe and stainless steel thin-wall articulation is 0.3-1.2mm.The 1st rabbet joint type is soft to be moulded sheath 2 and is held to be connected in the same way with inner sleeve 2-2 and by outer sleeve 2-1 and form monolithic construction.The 2nd rabbet joint type is soft to be moulded sheath 4 and is held to be connected in the same way with inner sleeve 4-1 and by outer sleeve 4-2 and form monolithic construction.For the syndeton that adopts two sections steel thin wall penetration pipes, its the 1st section steel thin wall penetration pipe 1 rear port moulded sheath 2 and straight joint 5 or 6 anterior connections of elbow by the 1st rabbet joint type is soft, and this straight joint 5 or elbow 6 rear portions are connected with the 2nd section steel thin wall penetration pipe 1-1 front port by the soft sheath 2 of moulding of the 1st rabbet joint type.Can be provided with at articulation or straight joint or elbow sidewall and to end tight screw, with fastening corresponding penetration pipe.
Compared with prior art, the utlity model has following beneficial effect:
(1) because penetration pipe of the present utility model and articulation, straight joint, elbow all adopt stainless sheet steel to make, its wall thickness is 0.3-1.2mm, thereby, in light weight, not corrosion, long service life, convenient transportation and site operation, production cost is lower than galvanized iron spool, cost performance is strong, and appearance and modeling is attractive in appearance.
(2) in the erecting bed, need the stainless steel thin-wall penetration pipe to be cut according to on-site actual situations; thereby serious burr arranged in that its port is residual; and the stainless steel thin-wall articulation; straight joint; also there is burr in the end of elbow; because the utility model is two soft sheaths of moulding of rabbet joint type of employing in the connecting of stainless steel thin-wall penetration pipe and stainless steel thin-wall articulation; the junction tightly is with the soft sheath of moulding of the 1st rabbet joint type between stainless steel thin-wall penetration pipe port and stainless steel thin-wall articulation port; like this; this junction favorable sealing property has also been sealed burr and has been protected pipe inner cable line insulating layer not to be damaged.Because stainless steel thin-wall articulation external thread part tightly is with the soft sheath of moulding of the 2nd rabbet joint type, after making this articulation and the terminal connection box being connected, its insulating barrier can not damaged by the burr of articulation port when cable penetrated the terminal box inner chamber, and sheath can not move or break away from the origin-location after construction or construction, can not injure the cable insulating barrier when guaranteeing to keep in repair when penetrating cable or later on.Stainless steel thin-wall penetration pipe of the present utility model can adopt one section, two sections, more than three sections or three sections, carry out being tightly connected of random length by straight joint or bent sub and the soft sheath of moulding of the 2nd rabbet joint type.As seen, after adopting the utility model structure, in cable penetration pipe and articulation thereof, straight joint, elbow, adopt thin-wall stainless steel just to become possibility, but it except that have easy construction, threading bidirectional operation and cost performance superior, also has favorable sealing property between penetration pipe and accessory and the connector, the generation that can effectively prevent to manage the improper factor of internal cause and cause naked light, fail safe is good.
The utility model can be widely used in power cable, industry or resident's light conduits etc. of electric equipment and make penetration pipe usefulness, but both the open-wire line installation also can be buried wall, be buried ground concealed wire installation.
