Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments the utility model, be elaborated:
Fig. 1 is perspective view of the present utility model;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of rail locking device, comprises base 110, spill spin block 120, clamping bar 130, moving fixture block 140 and spacer pin 150.
It is block that base 110 is.
It is block that spill spin block 120 is, and it is rotationally connected with the top of base 110 by a vertical rotating shaft 160, and the front end of this spill spin block 120 is provided with handle 121, operates this handle 121, can make spill spin block 120 rotations.
The head of clamping bar 130 and base 110 are fixing, and its afterbody has the hook-shaped quiet chuck 131 with rail adaptation.
Particularly, on base 110, have screwed hole, the head of clamping bar 130 has the screw thread with screwed hole adaptation, adjustable being fixed in screwed hole of head of clamping bar 130.
Moving fixture block 140 and quiet chuck 131 positioned opposite, and this moving fixture block 140 is articulated with on spill spin block 120, on this moving fixture block 140, a side relative with quiet chuck 131 has the notch 141 with rail adaptation.
Particularly, the rear end of spill spin block 120 has hinged mouthful, and the front end of moving fixture block 140 has the hinged end adaptive with hinged mouthful, and hinged end is inserted in hinged mouthful, and hinged with hinged mouthful by a rotational pin 170.
Particularly, the notch 141 of moving fixture block 140 is interior narrow outer wide trapezoidal shape.
Moving fixture block 140 and quiet chuck 131 are for being arranged in the both sides of two rail joint portions, by operating grip 121, make spill spin block 120 rotations, when moving the minimum distance position of fixture block 140 arrival and quiet chuck 131, moving fixture block 140 can be pressed on the side of above-mentioned rail joint portion just, realize the locking of rail, and locking force is consistent, easy and simple to handle, efficiency is high.
When moving fixture block 140 arrives the minimum distance position with quiet chuck 131, need by spacer pin 150 spacingly, to prevent that spill spin block 120 from crossing, rotate, this spacer pin 150 is fixed on the upper surface of base 110, and adjacent with a side of spill spin block 120.
In order to make the locking of rail more reliable and more stable, in notch 141, there is the spring leaf 142 of bar shaped, this spring leaf 142 is the shape that arches upward laterally, and its two ends are fixed on the both sides end face of moving fixture block 140.
In order further to improve the stable and reliability of rail locking, on base 110 and spill spin block 120, there is the pin hole that can communicate, in this pin hole, insert corresponding latch and can prevent that spill spin block 120 from back rotating.
Particularly, handle 121 is dismountable to be fixed on spill spin block 120, when operating this handle 121 and making above-mentioned articulated section move to the minimum range with quiet chuck 131, detachable lower handle 121 is also used as latch and is used, and only need make the size adaptation of above-mentioned pin hole and handle 121.
