Abstract
The invention provides a rapidly-locking two-dimensional hinge assembly part. A body is composed of a pair of hinge blocks, wherein the side edges of the pair of hinge blocks are provided with hinge teeth which are meshed in a crossed mode, and an upper conical through hole and a lower conical through hole are symmetrically manufactured in the middles of the meshed hinge teeth. An upper conical sleeve shaft and a lower conical sleeve shaft are matched in the conical through holes. A flat half-round head threaded rod penetrates in the conical sleeve shafts, one end of the flat half-round head threaded rod is connected with a fork head spanner, and the other end of the flat half-round head threaded rod is connected with the lower conical sleeve shaft. An eccentric protrusion is manufactured at the position, close to the lower portion of a handle, of the fork head spanner, depending on the mechanism, the fork head spanner can be pressed to rapidly lock the two-dimensional hinge assembly part, the other side edge of the left hinge block and the other side edge of the right hinge block are respectively provided with one end, depending on the ends, the assembly part can be respectively connected with two segments of metal tubes together, and the upper conical sleeve shaft and the lower conical sleeve shaft can generate positive pressure and static friction force in the axial direction and the radial direction at the same time, so that the requirements for relative movement and temporary fixing between the metal tubes are met.
Description
Technical field
The present invention relates to a kind of mounting structure for metal tube frame device.
Background technique
Metal tube frame device a lot, as building scaffold, finishing climbing frame, riser, display frame, metal control furniture, medical treatment and nursing utensil etc.; Connection scheme between metal tube is also a lot, and fixing connection can adopt thermal weld, and the cold Jie of rising ，rivet connects, internal and external threads socket etc., and movable connection can adopt hinge, pipe collar, anchor ear etc.Generally more complicated all of these connection scheme techniques and operation, on the relatively movable mounting structure market that needs again temporary fixed connection, not yet there is finding for needing between metal tube, based on this actual demand of metal tube frame device, the invention provides a kind of quick lock in two dimension hinged fitting.
Summary of the invention
The technical solution adopted in the present invention is: invention main body connects articulation block by a left hinged block and a right side and forms, they adopt metallic material manufacture, described left hinged block and right hinged block side are respectively shaped with the semicircle cylindricality hinge tooth of two engagements that cross one another, in the middle of described semicircle cylindricality hinge tooth, be shaped with, descend two groups of cone-shaped holes of symmetry each other, every group of cone-shaped hole forms a coherent taper shape connecing of kissing and splits on the hinge tooth of adjacent engagement, on this, the disc that the circular cone small end of lower two cone-shaped holes forms overlaps on the separating surface of middle two engagement hinge teeth, described is upper, lower two each other in symmetrical cone-shaped hole corresponding matching, lower two circular cone sleeves, upper circular cone sleeve is manufactured Qie Zhou center with ABS engineering plastics and is shaped with a through hole, lower circular cone sleeve is manufactured Qie Zhou center with metallic material and is shaped with a screw, described is upper, the cone height of lower two circular cone sleeves is all than corresponding coordinating upper, the high short 3mm-5mm of cone of lower conical bore, therefore between their circular cone small end face, just form a fit up gap, one is connected as a single entity described left hinged block and right hinged block can rotate through penetrating the through hole in upper circular cone sleeve after a pad again and screwing in the screw in lower circular cone sleeve with depressed semicircle head screw rod, in the middle of the depressed semicircle head of described depressed semicircle head screw rod, be shaped with an aperture, a bearing pin is by the aperture in the middle of this depressed semicircle head, again with a jaw spanner on pin-and-hole in jaw match and merge and can rotate, it is protruding that described jaw spanner is made a bias near the below of handle, respectively be shaped with an internal thread termination at described left hinged block and right hinged block corresponding to the side of hinge tooth, this internal thread termination is taken over and is matched and two sections of metal tubes can be linked together with outside thread respectively.
The cross one another semicircle cylindricality hinge tooth of engagement of the left and right hinged block side of main body of the present invention can be made between 3-5 pair in addition, has the cross one another semicircle cylindricality hinge tooth of engagement of 6-10 sheet, to strengthen its stability in the horizontal direction.
The left and right hinged block of main body of the present invention can be shaped with a male threaded stub in addition corresponding to the side of hinge tooth is each, and this male threaded stub is taken over and matched and two sections of metal tubes can be linked together with internal thread respectively.
The left and right hinged block of main body of the present invention is corresponding to an each square cylinder termination, rectangular cylinder termination, elliptic cylindrical termination, the hexagon cylinder termination of can being shaped with in addition of side of hinge tooth, or rectangular tube termination, rectangular tube termination, oval pipe termination, hexagonal tube termination, two sections of metal tubes that connect correspond to rectangular tube, rectangular tube, oval pipe or hexagonal tube, and it is fixing that connected mode adopts close-fitting to merge with rivet nail.
The left and right hinged block of main body of the present invention is corresponding to an each T-shaped cylinder termination, the I shape cylinder termination of can being shaped with in addition of side of hinge tooth, or T-shaped pipe end, I shape pipe end, two sections of metal tubes that connect correspond to T-shaped pipe, I shape pipe, and it is fixing that connected mode adopts close-fitting to merge with rivet nail.
The programmed sequence of operations of quick lock in assembly parts of the present invention is: the eccentric jaw spanner of first erect rotating it to intersects the semicircle cylindricality hinge tooth of engagement and rotates the position becoming tightly but still can be movable, clockwise direction is depressed eccentric jaw spanner again, now eccentric protruding pad and the upper circular cone sleeve depressed, shorten described upper, fit up gap between lower two circular cone sleeves, on, lower circular cone sleeve and upper, the pressure producing between lower round taper hole and static friction power are by two-dimentional hinged fitting quick lock in, just will be attached at a left side simultaneously, two sections of round metal tubes on right hinged block termination are fixed on the two dimension angular setting.
The invention has the beneficial effects as follows: the rotating shaft in assembly parts connects form with upper and lower circular cone sleeve with the kiss of upper and lower round taper hole and contacts, area of contact between them is larger, and positive pressure and static friction power can axially and radially produced simultaneously, the more single axial force of resistance producing strengthens a lot, the steadiness of metal tube frame device is strengthened, and eccentric jaw wrench operated in structure of the present invention is easy to be reliable, making to need between metal tube relatively movablely needs again the demand of temporary fixed connection to be met.
