Abstract
The utility model discloses a telescopic cam locking and connecting structure which is provided with a lock cavity arranged on a drive connecting element, a lock connecting apparatus is installed in the lock cavity, and a lock connecting slot matched with the lock connecting apparatus is arranged on a driven connecting element. The lock connecting apparatus is a telescopic cam locking structure comprising a cam base, a main cam, lock arms, a return spring and a detaching cam. The main cam is positioned and installed in the telescopic displacement cavity of the cam base, and the highest top of the main cam is rotated for 180 degrees to make the entire locking mechanism extended or retracted. After the highest top finishes the pushing action to the locking mechanism, the secondary high top drives the locking mechanism to be tightly locked after slightly moving back. The most significant end of the two lock arms is provided with a locking boss used for locking the lock connecting slot of the driven connecting element, and the lock arms are retracted back into the lock cavity when the lock arms are not locked and connected. The utility model is used for connecting the sectional material, etc, especially when crossed and connected into a frame body structure, under the condition that two driven connecting ends are fixed, the convenient and quick connection can be implemented, the connecting structure is provided with very high vertical stress performance, and the connection is firm and stable.
Description
Technical field
The utility model belongs to the linkage structure technology, and specific design is a kind of to be used between two objects the telescopic camlock linkage structure that especially connects between the section bar.
Technical background
Adopting the exhibition apparatus fast construction exhibition of standard piece and prefabricated is the direction of puting on display the boundary now, has the minimizing waste, thereby saves resource, environmental protection, characteristics of high efficiency.In the building of exhibition apparatus, there is certain problem in connection between the Liang Yuliang, post that is used for floor structure that for example has and the connector between the beam, employing forms the connecting plate latch fitting amplification of Germany gram difficult to understand Tom series, the function of gram Tom latch fitting difficult to understand is tension and fixing, can not be stressed, more can not be stressed at dead bolt movement direction (with the connecting groove Vertical direction).From domestic and foreign literature visible part beam and being connected of beam T-shape or two T-shape connecting plate being installed in advance the connecting groove of the both sides of beam by elder generation, realize being connected between beam and the beam by connecting plate again, in installation process, then can original beam of must dismantling be reinstalled because of installing connecting plate additional as increasing beam.These problems have influenced soundness, bearing and the Security of frame, platform.
Summary of the invention
The purpose of this utility model is the above-mentioned defective at the prior art existence, designed a kind of telescopic camlock linkage structure, this structure is used for the connection between the section bar, when especially interconnection becomes frame structure, be connected under the situation that end all fixes two and can realize connecting easily and fast, and linkage structure has very high vertical stress performance, and it is stable to be connected firmly.
The technical solution of the utility model:
Telescopic camlock linkage structure, it has the lock chamber that is arranged on the active link, and lock is equipped with the interlocking device in the chamber, and the locked groove that cooperates with the interlocking device is arranged on the passive link.Described interlocking device is a kind of telescopic cam lock holding mechanism, is made up of cam chair, main cam, hammerlock, returning spring and detaching cam; Main cam is connected the location by the positioning rotating shaft pin with the active link, and is arranged in the telescopic displacement chamber of cam chair; Main cam has the highest summit and time high summit, and the whole locking mechanism of the highest summit rotation 180 degree promotions stretches out or withdraws, and inferior high summit is that the drive locking mechanism is locked after the travelling backwards slightly after the highest summit is finished locking mechanism release action; The cam chair front end connects the hammerlock of a pair of symmetry, and the front portion of two hammerlocks has relatively separately or the activity space that closes up in the lock chamber, and is connected with the returning spring that resets to opposite direction, is provided with detaching cam between two hammerlocks; Two hammerlocks the locking boss arranged foremost, be used for and the T type locked groove locking that is connected on girder or the secondary beam, hammerlock is shunk back when unlocked in the lock chamber of active link.When needing to connect, by rotating main cam, actuating cam seat, make hammerlock stretch out the lock chamber, when the hammerlock end pushes against the interlocking cell wall of connected piece, rotate detaching cam again, make two hammerlocks overcome the power of returning spring and open, the locking boss promptly pins with T type locked groove.
Further, the telescopic displacement chamber is provided with damping spring in the front side of telescopic displacement direction, leave the buffer space that holds camber of spring between damping spring and chamber, the front side wall, the maximum boundary dimension of main cam is approximately less than the distance between telescopic displacement chamber rear sidewall and the damping spring.Above-mentioned design is in order further to reach the purpose of locking.Because, after supporting, boss and T type locked groove just finish interlocking if directly take to lock, can exist certain loosening between two links.The displacement amount of the highest summit that we design main cam during near damping spring just supports the displacement amount of interlocking cell wall for hammerlock, and being rotated further the redundant displacement amount of bringing, cam absorbs by damping spring, after the highest summit of main cam leaves damping spring, the inferior high summit of main cam acts on telescopic displacement chamber rear sidewall, drive the travelling backwards slightly backward of whole locking mechanism, locking boss and T type locked groove are realized locking.
The advantage of this telescopic camlock linkage structure is:
1, owing to the interlocking device in this linkage structure is shunk back in the lock chamber at the unlocked state, being connected under the situation that section bar all fixes of two ends, the section bar that is connected that does not need moving two ends during connection, the active connection profile can be put into two by the precalculated position earlier and be connected between the section bar, again the interlocking device is stretched out interlocking and be connected section bar, gram has been obeyed the shortcoming of existing locking mechanism thus, and is easy to connect, simple, easy disassembling.
2, by the matching design of two cam summits and buffering spring, behind interlocking, can further realize travelling backwards locking, make connection more stable firmly, can also avoid the stuck of cam-retractable locking linkage structure.
3 owing to adopt cam-retractable locking linkage structure, and the various alternating forces under can taking the weight guarantee that the stable of whole stand can be firm.Under the heavy burden
This locking linkage structure can be used for the connection of various Combined shelf bodies in building, and the connection that is particularly useful for having the section bar of higher heavy burden requirement to make up can form standard, unified connector.
