Abstract
The utility model discloses a built-in node formed by orthogonally connecting pipe bodies. The built-in node comprises a first pipe body and a second pipe body which are orthogonally placed, wherein a pipe orifice of the first pipe body is butted with a pipe wall of the second pipe body; and a built-in clamping piece is arranged in the first pipe body, limited and fixed with the inner wall of the first pipe body and fixedly connected with the side wall of the second pipe body through connection bolts. By the built-in node, steel pipes are flexibly connected, and processes such as a welding process are not required; the built-in node is convenient to mount, more importantly, coatings on the surface of the pipes are not damaged, the anti-corrosion capability of the pipes is greatly improved, and the service life is prolonged; and simultaneously, the pipes are stably and reliably connected, and shortcomings such as dislocation, deformation and inelegant appearance are overcome when the pipes are flexibly connected, so that the built-in node has a great practical value.
Description
Technical field
The utility model relates to a kind of Placement of tubing, specifically the built-in node of relevant tubing quadrature connection.
Background technique
Steel pipe has light and firm characteristics because of it, be widely used in and make various protective gratings, lattice door, burglary-resisting window, venetian blind etc., different size is cut into some sections through the steel pipe that sprays by size, through link, these lengths of steel pipes are coupled together again, traditional Placement is to adopt directly to be welded to connect or L shaped built-in connection plug-in unit connection, directly welding can cause the rust preventive coating of joint to destroy, and uses a period of time that corrosion occurs and affects attractive in appearance and working life; Adopt built-in connection plug-in unit can occur connecting not firm, easily loosening, the dislocation distortion, the defective such as outward appearance is indecency loses original antitheft and meaning of intercepting such as protective grating, lattice door, burglary-resisting window, venetian blind.
The model utility content
The model utility purpose: the purpose of this utility model is in order to solve above the deficiencies in the prior art, a kind of easy, as to be difficult for quadrature connection loosening, not deface coating built-in node that connects to be provided.
Technological scheme: the built-in node that quadrature described in the utility model connects, its objective is such realization: the built-in node that a kind of quadrature connects, the first body and the second body that comprise mutually orthogonal placement, the mouth of pipe of described the first body docks with the tube wall of the second body, the inside of described the first body is provided with built-in fastener, built-in fastener and the first inboard wall of tube body are spacing fixing, and affixed by the sidewall of connecting bolt and the second body.
Be provided with supporting base between the tube wall of the mouth of pipe of described the first body and the second body, described supporting base prevents that with the limit eaves that can support the first body the first body from rocking.
Described supporting base be the bottom with the engineering plastics of boss, and offer the jack corresponding with boss on the tube wall of the second body, strengthened the stability of the first body, be convenient to simultaneously the accurately position of location the first body and the second body connected node of assembly crewman.
Described supporting base also can with the shape of thin plate punching one-tenth with rivet hole, be fixed in supporting base on the sidewall of the second body by rivet.
Described built-in fastener is fixedly connected with by the inwall of dismounting-proof bolt with the first body.
The quantity of described connecting bolt is two, is symmetricly set on the both sides of built-in fastener.
Described built-in fastener sectional shape is U-shaped, is provided with the tapped hole that connecting bolt is installed at its back side, has saved material.
Described the first tubing is square tube, and described built-in fastener is the square iron that is threaded the hole, makes built-in fastener more firm with being connected of the second body.
On described the second tube wall, position, connecting bolt opposite is provided with the screw lid.
The mouth of pipe of described the second body is provided with capping, and the material of capping is engineering plastics.
Beneficial effect: the built-in node that quadrature described in the utility model connects makes the connection of steel pipe become more flexible, and do not need to adopt the techniques such as welding, easy for installation, the more important thing is the outward appearance coating of not destroying tube surfaces, greatly improved the anti-corrosion capability of tubing, extended working life, simultaneously secure and reliable connection, the defectives such as flexible connection difficult generation dislocation distortion and outward appearance are indecency have use value.
