Abstract
The invention relates to a telescopic connection device which comprises a shaft sleeve A, a shaft sleeve B, a main shaft, a clamping plate and positioning spring screws, wherein the shaft sleeve A and the shaft sleeve B are respectively fixed at the corresponding position of a unit body required to be connected; the external diameter of the main shaft is matched with the internal diameter of the shaft sleeve A; the external diameter of the main shaft is connected with the internal diameter of the shaft sleeve B; an annular groove is arranged at the head part of the main shaft; the annular groove is matched with the clamping plate; through screw threads are arranged on the lateral wall of the shaft sleeve B; the positioning spring screws are matched with the through screw threads in specification and are assembled in the through screw threads; a sliding groove is arranged on the main shaft; screw heads of the positioning spring screws are sleeved in the sliding groove; and the sliding groove is provided with concave pits matched with the screw heads of the positioning spring screws. The telescopic connection device is improved aiming at the above problems and effectively solves the problems that an entire display screen is slow to suspend and put up, is quick to disassemble and the like.
Description
Technical field
The present invention relates to be connected and fixed device, relate in particular to LED display cell cube room machine linkage structure.
Background technique
In view of lifting in the current LED display industry, lease display applications more and more widely, and lift, lease applied environment and ageing (for example stage the building with display screen) of display screen because of its uniqueness, the display screen splicing all exists more highly difficult, dismounting bothers.
Summary of the invention
The present invention is directed to above-mentioned problems and correct, make product can quite effectively solve the whole screen of the suspension of display screen, fast construction and reach problems such as tearing screen fast open slowly.
Concrete technological scheme is:
A kind of scalable connection set, it comprises axle sleeve A, axle sleeve B, main shaft, clamp and spring set screw, described axle sleeve A is separately fixed on the cell cube corresponding position that needs to be connected with described axle sleeve B, described main shaft external diameter cooperates with described axle sleeve A internal diameter, described main shaft external diameter cooperates with described axle sleeve B internal diameter, described spindle nose has annular groove, described annular groove cooperates with described clamp, described axle sleeve B sidewall has logical screw thread, described spring set screw specification and logical screw-thread fit also are assemblied in the described logical screw thread, on the described main shaft chute is arranged, the screw terminal of described spring set screw is socketed in the described chute, and described chute has the recess that cooperates with the screw terminal of described spring set screw.
It also comprises adjusting nut, and described main shaft afterbody has the screw thread that cooperates with described adjusting nut.After clamp blocked the annular groove of main shaft, the twisting adjusting nut made main shaft with axle sleeve A and axle sleeve B tension.The spring set screw skids off the recess on the main shaft.
Chute on the described main shaft has two recesses up and down.Main shaft is when free state, and the spring set screw withstands in the head recess of main shaft, makes main shaft be unlikely to landing, and after main shaft pushed axle sleeve A, before clamp blocked, the spring set screw withstood in the main shaft afterbody recess, made main shaft can not skid off axle sleeve A.
When workpiece needed closely to connect, main shaft slided into certain position, and the steel ball of spring set screw withstands main shaft and do not fall down, and mobile then clamp uses adjusting nut that workpiece is locked at last.The effect that this mechanism can reach quick connection, lock fast is applicable to lifting, lease display screen.
Main shaft, adjusting nut, axle sleeve B, spring set screw are fixed on the display screen unit body after being assembled into parts, and axle sleeve A, clamp are assemblied on another display screen unit body, can realize quick splicing between cell cube.
Description of drawings
Fig. 1 is an embodiment of the invention free state structural representation;
Fig. 2 is a structural representation behind the clamp on the embodiment of the invention;
Fig. 3 installs structural representation for the embodiment of the invention.
Wherein: 1. main shaft, 2. clamp, 3. adjusting nut, 4. axle sleeve A, 5. axle sleeve B, 6. spring set screw, 7. annular groove, 8. chute, 9. recess.
Embodiment
Describe the present invention by the following examples, should be noted that, cited embodiment should not understand the restriction to invention.
As shown in the figure: present embodiment is a kind of scalable connection set, it comprises axle sleeve A4, axle sleeve B5, main shaft 1, clamp 2 and spring set screw 6, described axle sleeve A4 is separately fixed on the cell cube corresponding position that needs to be connected with described axle sleeve B5, described main shaft 1 external diameter cooperates with described axle sleeve A4 internal diameter, described main shaft 1 external diameter cooperates with described axle sleeve B5 internal diameter, described main shaft 1 head has annular groove 7, described annular groove 7 cooperates with described clamp 2, described axle sleeve B5 sidewall has logical screw thread, described spring set screw 6 specifications and logical screw-thread fit also are assemblied in the described logical screw thread, on the described main shaft 1 chute 8 is arranged, the screw terminal of described spring set screw 6 is socketed in the described chute 8, and described chute 8 has the recess 9 that cooperates with the screw terminal of described spring set screw 6.
It also comprises adjusting nut 3, and described main shaft 1 afterbody has the screw thread that cooperates with described adjusting nut 3.After clamp 2 blocked the annular groove 7 of main shaft 1, twisting adjusting nut 3 made main shaft 1 with axle sleeve A4 and axle sleeve B5 tension.Spring set screw 6 skids off the recess 9 on the main shaft 1.
When workpiece needed closely to connect, main shaft slided into certain position, and the steel ball of spring set screw withstands main shaft and do not fall down, and mobile then clamp uses adjusting nut that workpiece is locked at last.The effect that this mechanism can reach quick connection, lock fast is applicable to lifting, lease display screen.
Main shaft, adjusting nut, axle sleeve B, spring set screw are fixed on the display screen unit body after being assembled into parts, and axle sleeve A is fixed on another display screen unit body, can realize quick splicing between cell cube.
Each component of this mechanical structure adopt machining to finish (its medi-spring set screw is state's tender), process easyly, and part is detachable, and the interchangeability height assembles easy.
1. main shaft, adjusting nut, axle sleeve are axial workpiece, and lathe can rapid processing be finished.
2. clamp is a hardware stamping spare, greatly the specification drawing.
3. the spring set screw is state's tender, very easily mass.
Obviously, foregoing is just in order to illustrate characteristics of the present invention, and is not limitation of the present invention, and the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the present invention should belong to protection category of the present invention.
