Abstract
The utility model relates to a connecting piece, in particular to a connecting-pipe sleeve, which comprises a pipe sleeve and locking bolts, wherein the middle part of the pipe wall of the pipe sleeve is symmetrically provided with limiting holes, the inner sides of the limiting holes are provided with a limiting plate, embedded holes are arranged on the pipe wall at both sides of the limiting holes, a nut is welded in each embedded hole, and each bolt is installed on the nut. The connecting-pipe sleeve has the beneficial effects that: the connecting-pipe sleeve is provided with the bolts with a locking function in double directions; after a connecting pipe is inserted, the connecting pipe is locked by screwing the bolts; and the connecting-pipe sleeve has the advantages of safety in use, stability, firmness, simpleness in operation and freeness in disassembly.
Description
Technical field
The utility model relates to a kind of connector, especially a kind of connection pipe box.
Background technology
In building trade, generally adopt scaffold to construct, and connect by connecting anchor ear between the scaffold, but traditional connection anchor ear less stable, part is more, and working strength is low, use is owing to influences such as shaking, twist, move, occurrence positions skew occurs breaking away from, situation such as loosening, disconnection, brings great potential safety hazard to construction.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple in structure, easy for installation, lock operation is simple and easy, and working strength is big, and fastness is strong, safe connection pipe box.
The technical scheme that solves its technical problem employing is: a kind of connection pipe box, comprise: pipe box, lock(ing) bolt, described pipe box tube wall middle part is symmetrically arranged with spacing hole, this spacing hole inboard is provided with limiting plate, the tube wall of these spacing hole both sides is provided with embedded hole, be welded with nut in this embedded hole, on this nut bolt be housed.
The beneficial effects of the utility model are: this connection pipe box has two-way bolt with lock function, after tube connector inserts, can tube connector be locked by tighting a bolt, and is safe in utilization, firmly stable, simple to operate, can freely dismantle.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model A-A generalized section.
Among the figure: pipe box 1, bolt 2, limiting plate 3, spacing hole 4, nut 5.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: as shown in the figure, a kind of connection pipe box comprises pipe box 1, bolt 2, limiting plate 3, spacing hole 4, nut 5.Described pipe box tube wall middle part is symmetrically arranged with spacing hole 4, and these spacing hole 4 inboards are provided with limiting plate 3, and the tube wall of these spacing hole 4 both sides is provided with embedded hole, is welded with nut 5 in this embedded hole, on this nut 5 bolt 2 is housed.
Operating principle of the present utility model is summarized as follows: at first bolt 2 is unscrewed, two tube connectors are inserted in the pipe box 1, with the end and limiting plate 3 apical graftings of tube connector, after tube connector all installs, bolt 2 is tightened, withstood tube connector, with the tube connector fix tightly by bolt 2.
