Technical field
This utility model is related to turn to transfer device, the universal joint in especially a kind of pull rod device.
Background technology
Universal joint generally comprises coupling assembly and multiple runner assemblies, and runner assembly to be reached with being flexibly connected of coupling assembly
To moving pivotally, the coupling assembly of such cating nipple is more, and connects complicated, once asking occurs in the mechanism at certain position
Topic, can lead to whole joint failure, the universal joint that this utility model is related to, using between single contiguous block and moving block
Hinge motion is realized in cooperation.
Utility model content
Technical problem to be solved in the utility model is to provide the universal joint in a kind of pull rod device.
For solving above-mentioned existing technical problem, this utility model adopts following scheme：Universal in a kind of pull rod device
Section, including pull bar, universal joint, described universal joint is made up of with moving block contiguous block, and universal joint disposes onboard, and pull bar is placed in
The light in the hole of protective jacket, pull bar one end is arranged on the screw thread in the hole of contiguous block, and the groove that contiguous block is provided with and moving block set
Some boss cooperate, and pass through pin connection, and the upper surface of moving block is provided with locking hole, is provided with screwed hole in moving block.
Preferably, described pin is provided with the open washer stepping up to connect.
Preferably, described screw thread in the hole is provided with the light hole face beneficial to assembly and disassembly.
Beneficial effect：This utility model adopts the universal coupling assembly of unitary type, by between contiguous block and moving block
It is flexibly connected, reach hinge motion, and the screwed hole being provided with coupling assembly is beneficial to the light face of installation.
This utility model employs the universal joint in a kind of technique scheme pull rod device of offer, compensate for prior art
Deficiency, reasonable in design, easy to operate.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial enlarged drawing of the present utility model.
Specific embodiment
As shown in Figure 1, 2, the universal joint in a kind of pull rod device, including pull bar 1, universal joint 2, described universal joint 1 is by even
Connect block 3 to form with moving block 4, universal joint 2 is placed on plate 5, pull bar 1 is placed in the unthreaded hole 7 of protective jacket 6, pull bar 1 one end sets
Put in the screwed hole 8 of contiguous block 3, the boss 10 that the groove 9 that contiguous block 3 is provided with is provided with moving block 4 cooperates, and
And connected by pin 11, the upper surface of moving block 4 is provided with locking hole 12, is provided with screwed hole 8, on described pin 11 in moving block 4
It is provided with the open washer 13 stepping up to connect, in described screwed hole 8, be provided with the light hole face 14 beneficial to assembly and disassembly.
During real work, cylinder pushing drawing rod 1 moves, and protective jacket 6 is arranged on pedestal, is provided with light due in protective jacket 6
Hole 7, so, the movement that pull bar 1 just can smooth in unthreaded hole 7, if adding lubricating oil in unthreaded hole 7, pull bar 1 when mobile more
Plus easily, in the screwed hole 8 that pull bar 1 is mounted in contiguous block 3 in motion, it is provided with one section of light hole face 14 in screwed hole 8,
Thus forming one section of space, play the effect being convenient to mount and dismount, contiguous block 3 is connected by a pin 11 with moving block 4, and
Open washer 13 is provided with pin 11, moving block 4 operationally swings constantly, single pin 11 connect can not accurately ensure turn
Motion block 4 moves, and open washer 13 here functions as the effect being stably connected with, and universal joint is placed on plate 5, the horizontal line of universal joint
Consistent with the horizontal line of pull bar 1, protective jacket 6, so, guarantee universal joint effectively works, and the pull bar 1 of the other end is arranged on
In the thread groove 8 of moving block 4, moving block 4 upper surface is provided with locking hole 12, can be with adjusting tightness, when conveying sets when connecting
For during by steel pipe socket on pull bar 1 herein, pull bar 1 is lifted by elevating mechanism, and now, moving block 4 is rotated up around pin 11,
So, steel pipe is not fall off during rising.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
Belong to those skilled in the art described specific embodiment can be made with various modifications or supplement or using similar
Mode substitute, but without departing from of the present utility model spirit or surmount scope defined in appended claims.
