Abstract
The utility model provides a connecting and locking device for section tubes, which can be installed at the connecting part of two section tubes. A fixing sleeve is mounted at an end with big caliber of one section tube; the inner hole of the fixing sleeve adopts an eccentric round hole; a section tube notch is formed on the inner wall of the end with big caliber; a clamp sleeve is arranged in the fixing sleeve; a clamp sleeve notch corresponding to the section tube notch is arranged on the clamp sleeve; a top block is embedded between the section tube notch and the clamp sleeve notch; and the end with a small caliber of the other section tube is mounted in the clamp sleeve. The utility model has the advantages of aesthetic appearance and simple and easy fastening method; and the section tube can be connected and locked only through mutual friction and a tight fit of the special top block and the irregularly-shaped clamp sleeve.
Description
Technical field
The utility model belongs to locking device, particularly a kind of connection locking device of steel tubing in different shapes.
Background technique
In video display industry ST Studio, often need be with the light fixture parallel shift of hanging to adjust irradiating angle.Hang the parallel shift of light fixture and need use a very long pipe (perhaps bar) to adjust light fixture usually, will adopt steel tubing in different shapes sometimes, if but long tube is oversize, can produce bending deflection, and influence is used, and therefore often needs the connection of more piece pipe is used.When the more piece pipe is connected use, generally adopt external thread bolt connection to use nut check again, tube wall thin and thick length all can be brought operational inconvenience, and it is unreliable to lock; Two pipes of the employing that has are done coaxially in conjunction with fine rotation it to be fixed each other, if but adopt steel tubing in different shapes to connect when using, this mode is difficult to steel tubing in different shapes is connected locking.
Summary of the invention
Can't realize connecting the problem of locking for solving steel tubing in different shapes, the connection locking device of a kind of steel tubing in different shapes of the present utility model can move arbitrarily according to need of work, is parked in certain interconnective steel tubing in different shapes locking of naming a person for a particular job, fastening means is simple, and is easy to use, firm.
The technological scheme that the utility model adopted is: a kind of connection locking device of steel tubing in different shapes, the tubule of steel tubing in different shapes are directly held the big caliber end that is set in another steel tubing in different shapes, and this connection locking device is installed in the socket place of two steel tubing in different shapess; On the big caliber end of described steel tubing in different shapes adapter sleeve is housed, the endoporus of this adapter sleeve is an eccentric circular hole; The inwall of big caliber end has the steel tubing in different shapes notch, is equiped with cutting ferrule in the adapter sleeve, and this cutting ferrule is provided with and the corresponding cutting ferrule notch of steel tubing in different shapes notch, and a jacking block embeds between steel tubing in different shapes notch and the cutting ferrule notch; The steel tubing in different shapes tubule is directly held and is installed in the cutting ferrule.
One side with steel tubing in different shapes notch plane contact in the described jacking block is the plane, and another and the contacted one side of adapter sleeve inwall are arc shaped surface, and its arc shape and adapter sleeve inwall match.
The working principle of this device is: in the steel tubing in different shapes joint of mutual socket, adapter sleeve is enclosed within outside the big caliber end of steel tubing in different shapes, the internal diameter of adapter sleeve is an eccentric circular hole, cutting ferrule notch in the adapter sleeve is corresponding with the steel tubing in different shapes notch on the big caliber end inwall, jacking block is installed in two notches, when two steel tubing in different shapess are connected, adapter sleeve turns clockwise, the steel tubing in different shapes plane is withstood on the jacking block plane, the jacking block arc shaped surface withstands adapter sleeve inwall arc shaped surface, because in the adapter sleeve is eccentric circular hole, when rotating to the little inwall of diameter, jacking block is compacted under the wall friction in the adapter sleeve eccentric circular hole, and jacking block compresses the steel tubing in different shapes tubule that is installed in the cutting ferrule simultaneously and directly holds, thereby with steel tubing in different shapes and adapter sleeve locking.
The utility model has the advantages that: 1. be applicable to the connection locking of steel tubing in different shapes, fastening means is simple, only adopts special jacking block and special-shaped cutting ferrule mutual friction and drive fit mutually, can realize that steel tubing in different shapes connects locking; According in the performance to the length requirement of steel tubing in different shapes, all can lock in the steel tubing in different shapes arbitrfary point; 3. aesthetic in appearance, easy to use.

Number among the figure: 1. the big caliber end of steel tubing in different shapes; 2. adapter sleeve; 3. cutting ferrule; 4. jacking block; 5. eccentric circular hole; 6. cutting ferrule notch; 7. cutting ferrule endoporus; 8. steel tubing in different shapes notch; 9. the steel tubing in different shapes tubule is directly held; 10. plane; 11. arc shaped surface; 12. stop circle.
Embodiment
Fig. 1 to Fig. 7 is a preferred version of the connection locking device of the utility model steel tubing in different shapes.Referring to Fig. 1, the steel tubing in different shapes tubule directly holds 9 to be set in the big caliber end 1 of another steel tubing in different shapes, connects the socket place that locking device is installed in two steel tubing in different shapess.The adapter sleeve 2 that connects in the locking device is installed on the cylindrical of the big caliber end 1 of steel tubing in different shapes, and the endoporus of this adapter sleeve is eccentric circular hole 5 (as shown in Figure 2); The inwall of the big caliber end of steel tubing in different shapes has steel tubing in different shapes notch 8 (as shown in Figure 3), cutting ferrule 3 is installed in the adapter sleeve 2, this cutting ferrule is provided with and steel tubing in different shapes notch 8 corresponding cutting ferrule notches 6 (as shown in Figure 5), and a jacking block 4 embeds between steel tubing in different shapes notch 8 and the cutting ferrule notch 6; The steel tubing in different shapes tubule directly holds 9 to be installed in the cutting ferrule 3.
As Fig. 4 and shown in Figure 6, cutting ferrule endoporus 7 is special-shaped in the present embodiment, and its shape is identical with steel tubing in different shapes cylindrical shape, make the steel tubing in different shapes tubule directly hold 9 in cutting ferrule contact tightr, be convenient to lock.The cutting ferrule top has and stops that circle 12 matches with adapter sleeve 2.
When using the utility model, when turning clockwise adapter sleeve 2, the plane of steel tubing in different shapes notch 8 is withstood on jacking block plane 10, jacking block arc shaped surface 11 withstands the arc shaped surface of adapter sleeve inwall, because in the adapter sleeve is eccentric circular hole, when rotating to the little inwall of diameter, the jacking block effect can not become flexible steel tubing in different shapes and adapter sleeve locking.
Of the present utility model aesthetic in appearance, fastening means is simple, only adopts special jacking block and the mutual friction interference fit of special-shaped cutting ferrule, can realize the connection locking of steel tubing in different shapes, has made things convenient for video display industry ST Studio staff to use.
