Abstract
A pipe connecting device comprises a connecting pipe I, a connecting seat, plugs, and a connecting pipe II; the pipe connecting device is characterized in that the end of the connecting pipe I is provided with the plug and hinged with the connecting seat; the end of the connecting pipe II is provided with the plug and hinged with the connecting seat; via disposing of a connecting arm and a clamping bench on the connecting seat; the connecting pipe I can only rotate anticlockwise, the connecting pipe II can only rotate clockwise, and therefore, when the connecting pipe I and the connecting pipe II are under pressure, the connecting pipe I, the connecting pipe II, and the connecting seat remain the same, thereby realizing that pipes are in a horizontal state after being connected. The pipe connecting device is advantaged by simple structure, novelty and beauty, and suitability for use as a table and chair fitting.
Description
Technical field
The utility model relates to a kind of accessory of tables and chairs, especially relates to a kind of pipe joint.
Background technology
Chinese patent database discloses the utility model patent that name is called " but Combined foldable table of opening and closing " on August 26th, 2009, the patent No. is 200820167294.7, but a kind of Combined foldable table of opening and closing, comprise desktop, multirow table leg arranged side by side, the table leg top is fixedly mounted with contiguous block, table leg suit slide block is expert at, the contiguous block on the adjacent table leg of column direction connects the grizzly bar that at least one group of mutual top-bottom cross becomes the scissors structure with slide block with pivot pin, connects with pivot pin in the crosspoint; Contiguous block on the table leg that keeps to the side to be listed as is connected with slide block and is shaped with the joint that the right angle both direction is connected with grizzly bar, this contiguous block end face is shaped with one and cooperates pit or the projection of pegging graft with the projection in bight, desktop bottom surface or pit, and the contiguous block on the table leg of middle column is connected with slide block to be shaped with and is mutually the joint that three directions in right angle are connected with grizzly bar; This contiguous block end face is shaped with two pit or the projections that cooperate grafting with projection or the pit in bight, desktop bottom surface.Articulated structure need to adopt table leg to support below hinged between this desktop, and this structure causes feed consumption many.For above-mentioned shortcoming, be necessary to make improvement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of pipe joint, simplifies syndeton, solves the many problems of feed consumption.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of pipe joint, and it comprises tube connector I, Connection Block, vexed plug, tube connector II; It is characterized in that tube connector I termination is provided with vexed plug, and be hinged with Connection Block; Tube connector II termination is provided with vexed plug, and is hinged with Connection Block.
Described Connection Block is provided with brace, boss, linking arm, groove, hinge hole, Ka Tai; It is characterized in that linking arm is arranged between the parallel brace of sheet; Two groups of hinge holes arrange on the brace; Boss is arranged on the linking arm; Form groove between brace and the linking arm; Two Ka Tai are arranged on the inboard of two braces.
Gap difference tube connector I between the described card platform and the external diameter of tube connector II.
The beneficial effects of the utility model are: by linking arm and Ka Tai are set at Connection Block; Tube connector I can only rotate counterclockwise, Connection Block II can only clockwise rotate, thus when tube connector I and tube connector II are under pressure, tube connector I, tube connector II and Connection Block are still kept intact, realized keeping level after tubing connects, therefore the utlity model has the characteristics such as accessory use simple in structure, easy to operate and that be suitable as tables and chairs.

Fig. 2 is the schematic perspective view of the utility model Connection Block.
Fig. 3 is the structural representation that the utility model uses state.
Fig. 4 is the structural representation in the utility model folding process.
Fig. 5 is the structural representation after the utility model folds.
The specific embodiment
Below by embodiment, and with reference to accompanying drawing the technical solution of the utility model is described further.
Embodiment: with reference to Fig. 1, a kind of pipe joint, it comprises tube connector I1, Connection Block 2, vexed plug 3, tube connector II4; It is characterized in that tube connector I1 termination is provided with vexed plug 3, and be hinged with Connection Block 2; Tube connector II4 termination is provided with vexed plug 3, and is hinged with Connection Block 2.
With reference to Fig. 2, described Connection Block 2 is provided with brace 21, boss 22, linking arm 23, groove 24, hinge hole 25, card platform 26, described linking arm 23 is arched arm, groove 24 is complementary with tube connector I1 and tube connector II4, and the spacing between the described card platform 26 is less than the external diameter of tube connector I1 and tube connector II4.
With reference to Fig. 3, during use, tube connector I1 and tube connector II4 are hinged on the Connection Block 2 in line, there is prolongation the termination of tube connector I1 and tube connector II4, prolongation and linking arm 23 are inconsistent, limit thus tube connector I1 and tube connector II4 and upwards rotated around pin joint, but allowed tube connector I1 and tube connector II4 to rotate around pin joint.
With reference to Fig. 4, when folding, only need rotate counterclockwise tube connector I1 around pin joint, tube connector II4 are clockwise rotated around pin joint get final product.
With reference to Fig. 5, when continuing to fold, continue tube connector I1 is rotated counterclockwise around pin joint, tube connector II4 is clockwise rotated around pin joint, until turning to parastate, tube connector I1 and tube connector II4 get final product.。
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, be equivalence that the utility model claim and description do and change and modify, should still belong in the scope that the utility model patent contains.
