Abstract
The utility model provides a universal joint. The universal joint is used for connecting trusses for putting up a stage. A joint body is provided with three connection chambers which protrude outwardly and are mutually vertical to each other. Each connection chamber of the joint body is connected to a truss through a chuck coupling mechanism. The universal joint is advantageous in that the installation is convenient and use for multiple times can be facilitated; connection effect between trusses can be guaranteed; stress demand for a stage can be met, and the universal joint is safe and reliable; cost is saved, and dismounting and transporting are convenient.
Description
Technical field
The utility model relates to a kind of jointing, particularly a kind ofly is used for the universal joint that stage is built truss.
Background technique
Because the raising of living standard; People are also more and more for the demand of cultural life; Requirement to spiritual life level is also increasingly high, therefore all often has the activity of theatrical performances miscellaneous or summary report and so in various places, and often owing to receive the restriction in place; These activities all can not all be carried out at the stage of having built up; And need build some makeshift stages, and building of makeshift stage needs to use a large amount of truss, all is through being welded to connect at present between each truss; Detaching products difficulty after can causing like this welding; And after regular meeting is with the dismounting of used truss, weld the time to be reused in the reality, thereby repeated use can cause the various specified stress decrease of weld to influence the bearing capacity of truss like this, if do not note just having the danger that causes stage to subside.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of universal joint that stage is built truss that is used for.
The utility model solves the technological scheme that its technical problem adopted:
A kind of universal joint; Comprise adapter body; Said adapter body is provided with three outwards mutually perpendicular in twos connection chambers of protrusion; The afterbody of each connection chamber is extended with the internal thread through hole that is used for the square bolt of dismounting, and each connection chamber on the adapter body is connected with truss is dismountable through chuck bindiny mechanism;
Described chuck bindiny mechanism comprises square bolt, and described square bolt comprises hexagon nut and double-screw bolt, and square bolt is sleeved in the connection chamber through the clamping dish;
Said clamping dish screws togather through its outside thread and connection chamber each other, and its center is provided with the interior threaded hole with square screw threaded;
Said square bolt screws togather through clamping dish and truss each other, and the clamping cover of clamping dish and the setting of truss internal fixation interconnects.
The position of said clamping dish and the clamping of clamping cover is provided with cross indent buckling opening, and said clamping cover is provided with the clamping bar relative with indent buckling opening flute profile, and said clamping cover is hollow structure.
The beneficial effect of the utility model is: the utility model couples together through the truss that adopts universal joint that stage is built, and adapter body is provided with three outwards mutually perpendicular in twos connection chambers of protrusion, and each connection chamber on the adapter body links to each other with truss through chuck bindiny mechanism; Make easy for installationly, be convenient to repeatedly use, and can guarantee the connection effect between each truss; Stress demand when satisfying the stage use; Safe and reliable, practice thrift cost, the dismounting convenient transportation.

Embodiment
With reference to Fig. 1 ~ 5, a kind of universal joint comprises adapter body 1; Said adapter body 1 is provided with three outwards mutually perpendicular in twos connection chambers 11 of protrusion; The afterbody of each connection chamber 11 is extended with the internal thread through hole 12 that is used for the square bolt 2 of dismounting, and each connection chamber 11 on the adapter body 1 is connected with truss is dismountable through chuck bindiny mechanism, is connected through between universal joint realization truss and the truss; Both guaranteed connection stability and be convenient to dismounting and be easy to carry about with one; Described chuck bindiny mechanism comprises square bolt 2, and described square bolt 2 comprises hexagon nut 3 and double-screw bolt, and square bolt 2 is sleeved in the connection chamber 11 through clamping dish 4;
Said clamping dish 4 screws togather through its outside thread and connection chamber 11 each other, and its center is provided with the interior threaded hole that screws togather with square bolt 2; Said square bolt 2 screws togather locking each other through clamping dish 4 and truss, and clamping dish 4 interconnects with the clamping cover 5 of truss internal fixation setting.
Said clamping dish 4 is provided with cross indent buckling opening 41 with the position that 5 clampings are overlapped in clamping; Said clamping cover 5 is provided with the clamping bar 51 relative with indent buckling opening 41 flute profiles; Said clamping cover 5 is a hollow structure; Mode through clamping can guarantee that its stability can be convenient to dismounting again, and clamping is simple in structure, is easy to processing; Can certainly adopt and be spirally connected; Riveted joint waits other Placements, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model; And adopt hollow structure can reduce total quality to greatest extent, more be convenient to transportation.
The working principle of the utility model: the utility model in use only needs through internal thread through hole 12 square bolt 2 to be screwed or unscrewed truss with inner hexagon spanner just can be easily truss and joint to be locked or unclamped; Easy to use, and it is reliable to connect effect stability.
The utility model couples together through the truss that adopts universal joint that stage is built, and adapter body 1 is provided with three outwards mutually perpendicular in twos connection chambers 11 of protrusion, and each connection chamber 11 on the adapter body 1 links to each other with truss through chuck bindiny mechanism; Make easy for installationly, be convenient to repeatedly use, and can guarantee the connection effect between each truss; Stress demand when satisfying the stage use; Safe and reliable, practice thrift cost, the dismounting convenient transportation.
