Abstract
The utility model provides a kind of linkage structure being easy to assemble and lock, for the connection that supporting frame intersection is connected between two beams, linkage structure comprises two snap closes, two lock pins, two decks and junction buttons, be connected by junction button between deck, snap close is articulated with deck, and lock pin is connected to deck, locked groove on snap close is connected with lock pin locks beam, described lock pin comprises cylindrical body and spheroid, and have the cavity placing lock pin spheroid in deck, cavity wall is provided with ring type screw thread; Described cavity wall is connected with cavity cap, and cavity cap adopts with cavity wall and is threaded.This linkage structure being easy to assemble and lock that the utility model provides, structure is simple, and be easy to assembling and locking, join strength is firm.
Description
Technical field
The utility model relates to a kind of linkage structure being easy to assemble and lock, and belongs to daily living article technical field.
Background technique
The barrel structure setting up and down that has that the connection of existing supporting frame cross coupling generally adopts two first to connect connects, and beam stretches in cylinder, realizes connecting.But this kind of linkage structure is generally and designs, and the angle for two beams intersected designs linkage structure in advance, after connection, is namely fixed between two beams intersected.It is very complicated that existing linkage structure designs in locking, causes manufacturing process complicated, connects inconvenient, is not easy to assembling and locking.
Model utility content
The utility model provides a kind of linkage structure being easy to assemble and lock, and can overcome the above problem, and structure is simple, and be easy to assembling and locking, join strength is firm.
For realizing the above technology, the technological scheme that the utility model provides is as follows: a kind of linkage structure being easy to assemble and lock, for the connection that supporting frame intersection is connected between two beams, described linkage structure comprises two snap closes, two lock pins, two decks and junction button, be connected by junction button between deck, snap close is articulated with deck, lock pin is connected to deck, locked groove on snap close is connected with lock pin locks beam, it is characterized in that, described lock pin comprises cylindrical body and spheroid, the cavity placing lock pin spheroid is had in deck, cavity wall is provided with ring type screw thread, described cavity wall is connected with cavity cap, and cavity cap adopts with cavity wall and is threaded.
Further, described cavity cap has cylindrical sidewall, the arranged outside screw thread of cylindrical sidewall, and the height of cylindrical sidewall extends to the lower hemisphere place of spheroid; The height of the ring type screw thread of corresponding cavity wall also extends to the lower hemisphere place of spheroid.
Further, the cylindrical body of described lock pin is provided with the groove radial each other centered by cylindrical body axle center, and the top of described groove has horizontal plane.
Further, the longitudinal section of described groove is square.
This linkage structure being easy to assemble and lock that the utility model relates to, locked groove on snap close directly places level due to snap close and the hinged reason of deck, it is spheroid bottom lock pin, spheroid can rotate freely in cavity, groove in cylindrical body is square groove, opened fluted place must attenuate, this carefully directly inserts in the locked groove of snap close at place.Again due to, the top of cavity has cavity cap, and cavity cap adopts the mode be threaded to stop spheroid to be extracted in cavity, therefore this linkage structure be a kind of be easy to assemble and locking linkage structure.
