The specific embodiment
See figures.1.and.2, stand connection 1 comprises main part 2, coating member 3, latch bar 4 and eccentric shaft assembly 5, and these assemblies further are shown in respectively among remaining figure.
This assembly 5 also comprises an end 23, and end 23 is a triangle at this, makes axle 18 rotations with the box spanner by an appropriate structuring.Assembly 5 comprises that further a stop flange 24 to be meshed with brake portion 25 on the main part 2, excessively rotates through its position latching so that prevent axle 18.
Central authorities' crank section 19 has a bending inner surface 26, and the curvature complementation of bending inner surface 26 and eyelet portion 15 inner surfaces of latch bar 4 is to rotate and smooth-going and positively mesh inner surface 27 when entering towards position latching when axle 18.
During use, eccentric shaft assembly 5 is not rotating between position latching and the position latching.At position latching not, as shown in Figure 1, central crank section 19 is in a high position, and wherein latch bar 4 can move freely on coating member 3; At position latching, as shown in Figure 1, central crank section 19 is in low level, and wherein latch bar 4 is pulled to main part 2 and supports cover member 3 makes it to prop up tightly pipe 6.Fig. 1 has shown position latching, and the central crank section 19 of its axis 18 is positioned at position shown in Figure 9.
In more detail, originally, latch bar 4 will not be attached to coating member 3, and freely suspend in midair for 18 times at eccentric shaft.For connector 1 being gripped to a pipe 6, main part 2 is placed on pipe 6 contiguous places, and coating member 3 is located on the pipe 6 and can rotates around pipe.Axle 18 rotates subsequently and makes central crank section 19 towards the top of flange 22, make latch bar 4 can between the coating member arm 11 with above freely sway, pallet part 17 can be put into the recess 12 of coating member thus.
Then, for example utilization rotates axle 18 with the spanner of a triangle shaped ends 23 engagements, makes central crank section 19 turn to low level, and the inwall 27 of mesh rod eyelet portion 15, and bar 4 is pulled to main part 2.When the middle body 19 of crank axle 18 moved down, bar 4 was by further pulled down, thus with coating member 3 toward drop-down and pipe 6 gripped the location.
The axle 18 rotate to a proper range make its be parked in lower position or near, causing pulling force in the latch bar 4 that eyelet portion 15 and axle 18 are compressed mutually by the pipe effect of gripping props up, and with eyelet portion 15 and axle 18 fixing location automatically, and can resist any lax moving thus.Stop flange 24 and detent 25 can be guaranteed that axle 18 does not excessively rotate and make that central crank section 19 can not begin to rise once again, and thereby release bar locking bar 4.Generally speaking, crank axle 18 needs fully to rotate so that act on strength on the latch 4 via coating member 3 and crank section 19 can be withdrawn near the high position.
The eyelet portion 15 that it should be noted that latch bar 4 has appropriate size, so when the central crank section 19 of axle 18 is in a high position, can be by hindering bar 4 engagement coating member recesses 12 against eyelet portion 15 inner surfaces 27 of living central crank section 19.Its size also can be so that central centre crank section 19 be positioned at low level or when low level, latch bar 4 can be in right amount down priming with the pipe 6 that is clamped.
The arm 11 of coating member has several recesses 12 adapting to the dimensional tolerance of pipe, thereby holds the pipe 6 of different size.Therefore, though the steel bracket pipe of standard is about 48 mm dias, pipe can change near this numerical value.Therefore, for bigger pipe 6, latch bar 4 will mesh recess 12 further towards the end of the arm 11 of coating member.
For connector 1 is disconnected, axle 18 only needs opposite spin also can remove from the arm 11 of coating member by release bar locking bar 4.
The main part 2 of connector 1 can comprise perforate or similar item, to be fastened to one or more miscellaneous parts, for example is connected to a wooden frame by bolt.
The the 11st to Figure 15 shows two kinds of such connectors 1 ' and 1 ".In these figure, the part corresponding with the connector of Fig. 1 to 10 figure has identical numbering.And belonging to first according to these parts still is second linkage unit and it is put on " a " or " b ".
With reference to Figure 11 to 13, connector 1 ' comprises two connector unit 50 and 60, each connector unit has the parts of similar first embodiment, but its main part 2a ' and 2b ' link together by central rivet parts 70, so two connector unit 50 and 60 are rotated relative to each other.This structure can make connector 1 ' that pair of brackets pipe 6 is installed with any relative angle each other.
These back two embodiment have shown that two of riveted separate the made connector 1 ', 1 of linkage units 50,60 "; but connector also can be the integral type structure, and wherein two linkage units 50 and 60 are installed on the opposite side of a common body part 2 (can adopt the cross shaped head of for example using in transverse connection).Two-piece construction can provide than integral type structure greater flexibility and lower cost.
Can be quick and attached simply and remove according to the connector of present embodiment, wherein only need the half-turn of crank axle 18 to rotate, so can save labour costs.And this connector is general only need be than the connector maintenance still less of the known technology that uses the screw-type bolt connection piece.
This connector can be general, for example is used for steel or other metallic support pipes are linked together.
Figure 16 and 17 has shown another connector 1 , it is similar to previous connector, but flange portion or arm 22 (setting-up eccentricity parts 5 on it) extend in the longitudinal direction, so that a supporting surface 90 is provided, when vertical installation connector 1 (so that support arm 22 are positioned at the arm shape part 7 below that coating member 3 are installed), on this supporting surface, can lay the support pipe of a level.
This feature helps at the support pipe that does not need installation level under other auxiliary situation, and allows the user that the support pipe of level is placed between a pair of connector and need not to tighten.Adjust the horizontal location of pipe before the user can be tightened on each connector on pipe then as required.Former, this program needs two people.It should be noted that by rotating eccentric part 5 simply pipe is fixed to the speed that can guarantee whole erection on the connector can further improves, and can the horizontal pipe of shortening be in the time of the state of not tightening.
Figure 18 has shown the connector 1 of two pipes
Iv, it has linkage unit 50 , 60 , and it constitutes with the connector of Figure 16 has identical mode.Can be with the pipe 6 of level
hBe placed on the supporting surface 90 of support arm 22 and do not need to tighten linkage unit 60 .This makes that support can be with connector 1
IvBe fixed to a pair of vertical support pipe 6
vEach on, then with the support pipe 6 of level
hBe placed in connector 1 in the mode that does not tighten
IvBetween.In case be positioned properly, support can rotate first eccentric part 5 , rotates another eccentric part then, so that with pipe 6
