Description

A kind of tent strut connector

Technical field

The present invention relates to the parts of tent support, especially relate to a kind of tent strut connector.

Background technology

The increase of Along with people's outdoor leisure activity, the use of tent is more and more universal, and the tent support requires not only to have good strength and stiffness as the skeleton of tent, also requires to have easy folding, be prone to open, and dismounting is characteristics easily.The tent support is made up of some struts and strut connector, and the upper end of each strut all is connected with the strut connector.There is following distinct disadvantage in present strut connector: 1, intensity a little less than, the member stress situation is bad, is prone to cause member to damage; 2, the member mounting or dismounting are inconvenient; 3, use inconvenience, need each root strut be opened one by one during use, time and effort consuming is also hindered hand easily.

Publication number is that the application for a patent for invention of CN1076987 discloses a kind of tent frame coupling device that can assemble rapidly and dismantle.Around union body, be provided with a plurality of grooves that separate certain angle, have a pair of fastening recess at the sidewall of each groove.Be formed with an engages step at the rear portion of each groove, be provided with a bolster with the frame member fasteners of each groove coupling, said bolster is with the recess coupling of groove.At the rear portion of bolster, be formed with a rake that will be coupled with the inclination engages step of groove.The tent frame member is inserted into respectively in the hole of frame member fasteners, and the frame member fasteners is mounted in the groove of union body.After the frame member fasteners is mounted to the groove of union body, be screwed on the union body through latch with a bolt.Need each root strut be opened one by one when this patent of invention is used, time and effort consuming is hindered hand easily; Member can not cushion stressed, is prone to cause damage.

Summary of the invention

The purpose of this invention is to provide a kind ofly improve the member ability to bear, avoid that member is impaired, mounting or dismounting safe, the tent strut connector that can open each strut synchronously easy to use.

For realizing the foregoing invention purpose, the present invention adopts following technical proposals:

The present invention is provided with bearing, gland, sliding sleeve, bull stick group, connection rod set, conduit, fastening bar and at least 1 spring;

Bearing is provided with central through hole, and the bearing external wall of upper portion is provided with the plural bearing draw-in groove that radially extends, and each bearing draw-in groove is uniformly distributed with, and each bearing draw-in groove inwall both sides is equipped with protruding axle caulking groove; Gland is fixed in the bearing upper surface through securing member; Sliding sleeve is provided with central through hole; The sliding sleeve outer wall is provided with a plurality of sliding sleeve draw-in grooves that equate with bearing draw-in groove quantity that radially extend; The phase angle of each sliding sleeve draw-in groove is identical with the phase angle of each bearing draw-in groove, corresponding 1 the bearing draw-in groove of each sliding sleeve draw-in groove, and each sliding sleeve draw-in groove and pairing bearing draw-in groove are in same axial plane; The bull stick group is provided with the bull stick that quantity equates with bearing draw-in groove quantity; Bull stick is provided with central blind hole; The blind end of bull stick is arranged in the bearing draw-in groove, the external tent strut of the openend of bull stick, and bull stick outer wall both sides are provided with protruding axle; The protruding axle of bull stick is rotatably assorted with the protruding axle caulking groove of bearing, and said formation bull stick and the bearing of being rotatably assorted is hinged; Connection rod set is provided with the connecting rod that equates with bull stick group bull stick quantity, and small end and bull stick are hinged, and the connecting rod lower end is arranged in sliding sleeve draw-in groove and side walls hinged with the sliding sleeve draw-in groove; Conduit is arranged in the central through hole of bearing central through hole and sliding sleeve, the central through hole coaxial inner conductor of conduit and bearing central through hole and sliding sleeve, and the fastening bar passes the central through hole of conduit; Fastening bar fastening bar bottom is provided with screw thread; Fastening bar lower end is furnished with locking nut, and said conduit is connected through fastening bar and sliding sleeve, and said sliding sleeve and conduit are slidingly matched; Each spring is located in the bearing centre bore, and each spring housing is outside conduit.

Said a plurality of bearing draw-in groove, preferably 4～10 bearing draw-in grooves.

Said gland preferably is provided with central through hole, and the gland periphery is provided with the plurality of openings groove, and the quantity of said open slot is identical with the quantity of bearing draw-in groove, and the open slot phase angle of gland is corresponding identical with bearing draw-in groove phase angle.

Said at least 1 spring is 2 springs, i.e. inner spring and outer spring, and 2 springs are the column type spring, and outer spring is enclosed within the inner spring outside.

Said bull stick openend is provided with cross through hole, and cross through hole is used for securing member and passes, and tent strut one end during the bull stick openend passes through securing member and inserts the bull stick blind hole is connected.

The hinged hinged support of said bull stick and bearing is first hinged support; The hinged hinged support of said small end and bull stick is second hinged support; The hinged hinged support of said connecting rod lower end and sliding sleeve draw-in groove is the 3rd hinged support; Line between line between said first hinged support and second hinged support and said second hinged support and the 3rd hinged support intersects, and the interior angle that intersects can be 130 °～180 °, is preferably 170 °～180 °.

Compare with prior art, the present invention has following outstanding substantive distinguishing features and obvious improvement:

Because bearing, sliding sleeve, bull stick group and connection rod set have constituted a plurality of planar linkages jointly, bearing, sliding sleeve, 1 bull stick and 1 connecting rod constitute a slider-rocker mechanism (planar linkage), and sliding sleeve (slide block) is shared; Bull stick is rocking bar; Connecting rod is connecting rod, and sliding sleeve is slide block, like this (any slider-rocker mechanism) during any 1 bull stick of folding; The capital drives sliding sleeve and moves up and down, and other slider-rocker mechanism also all can synchronous on-off.Interior angle is designed to 130 °～180 ° can make member obviously improve stress-bearing capability, improves stress.When interior angle less than 130 °, when bull stick can outwards launch when bull stick was folded, it is big that volume after folding becomes, and carries inconvenience, and can influence opening operation.When interior angle greater than 180 °, when bull stick forwards folded state to from open mode, can produce reaction force between bull stick and the connecting rod; Hinder folding; Must add active force in addition and offset this reaction force, the jackknife action crude benzol is obstructed, and make touching mutually between each bull stick; Cause the space between each bull stick to diminish, cause tent cloth to pack up difficulty.When interior angle is 170 ° to 180 °, just only need very little strength just can each bull stick be folded up.Through this angle design, the rotation ability to bear between bull stick and the bearing is significantly improved, can avoid bull stick to be damaged simultaneously.Because gland is fixed in the bearing upper surface through securing member, can prevent that like this dog link jumps out of, the protruding axle that guarantees bull stick is in the state of being rotatably assorted with protruding caulking groove of bearing, thereby makes bull stick reliable operation, safety good.
