Description
Technical field
The utility model belongs to track traffic facility technology field, particularly relates to a kind of rail locking device.
Background technology
Rail locking device is used for after rail switch, is locked by the joint of two rails, avoids joint to occur to loosen, forms potential safety hazard.Rail locking device comparatively early adopts nut to lock, and complex structure, complex operation, locking force is inconsistent, and efficiency is low.And newer rail locking device-application number is CN201420091658.3, disclosing one can utilize handle 121 to operate spill spin block 120, drive the dynamic fixture block 140 be installed on spill spin block 120, make the notch 141 of dynamic fixture block 140 coordinate grip track with quiet chuck 131; And the adjustment of clamping bar 130 length, people must be relied in the screwed hole in it screw-in base 110, during grip track, also need the manual turning handle of people etc., such design, structure is still too complicated, it is also convenient not to use, and deviate from it and makes the more simple object of structure.
Utility model content
In view of the above-mentioned problems in the prior art, main purpose of the present utility model is to address the deficiencies of the prior art, and provides a kind of rail locking device, while ensureing good locking property, simplifies the structure of device.
The technical solution adopted in the utility model is as follows:
A kind of rail locking device, comprise base, the sidepiece of base is hinged with dynamic fixture block, and the inner side of dynamic fixture block is provided with the notch suitable with rail; Base is provided with through hole along the opening direction of notch, is installed with clamping bar in through hole, and the opening side that clamping bar is positioned at notch is provided with hook-shaped quiet chuck, and the opposite side of clamping bar is provided with the position-arresting disk for fixing clamping bar.
Further, the cross section of described notch is interior narrow outer wide trapezoidal shape.
Further, the spring leaf of bar shaped is provided with in described notch.
Further, described spring leaf is in the shape that arches upward laterally, and its two ends are fixed on the end face of dynamic fixture block both sides.
Further, described clamping bar is divided into quiet chuck and pull bar two parts, and pull bar is provided with external screw thread, and quiet chuck and pull bar are threaded connection fixing.
Further, described position-arresting disk is installed on pull bar.
Further, the through hole two ends of described position-arresting disk are all fixed by nut.
In sum, compared with prior art, the beneficial effects of the utility model are:
The utility model more simplifies compared with the structure of prior art, eliminate with lever operated come the structure of control appliance clamping rail, and use clamping bar instead to control clamping; And dynamic fixture block is hinged on the sidepiece of base by the utility model, so, dynamic fixture block up and downly can only regulate suitable position; But clamping bar of the present utility model is passed by the through hole of base, people can be facilitated to control its length, operating personnel only just need can control the length of clamping bar by stretching pull bar, the mode clamped by the rotation of handle in the prior art of ratio is more quick, after clamping rail, can fix by squeezing into bolt to the bolt hole of position-arresting disk, further, top nut can also be added by through hole two on adjusting base, come by the nut at through hole two ends fastening further, make it the fastening effect not affecting rail.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
All features disclosed in this manual, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
As shown in Figure 1: a kind of rail locking device of the utility model embodiment, comprise base 1, the sidepiece of base 1 is hinged with dynamic fixture block 2, the inner side of dynamic fixture block 2 is provided with the notch 2-2 suitable with rail, the cross section of described notch 2-2 is interior narrow outer wide trapezoidal shape, be provided with the spring leaf 2-1 of bar shaped in described notch 2-2, described spring leaf 2-1 is in the shape that arches upward laterally, and its two ends are fixed on the end face of dynamic fixture block 2 both sides; Base 1 is provided with through hole 3 along the opening direction of notch 2-2, and through hole 3 is positioned at the below of dynamic fixture block 2 and notch 2-2 thereof; Clamping bar 4 is installed with in through hole 3, described clamping bar 4 is divided into quiet chuck 4-4 and pull bar 4-2 two parts, pull bar 4-2 is provided with external screw thread, quiet chuck 4-4 and pull bar 4-2 is connected and fixed by external screw thread, the opening side that clamping bar 4 is positioned at notch 2-2 is provided with hook-shaped quiet chuck 4-4(and quiet chuck 4-4 part), the opposite side (i.e. pull bar 4-2 part) of clamping bar 4 is provided with the position-arresting disk 4-3 for fixing clamping bar 4, and position-arresting disk 4-3 is installed on one end of pull bar 4-2; Be provided with the bolt hole 4-3-1 for squeezing into bolt in position-arresting disk 4-3, fixing for what ensure that bolt can be good, the length of this bolt should meet can in depth under requirement.Further, in order to reinforce clamping bar 4 further, rail is held tighter, the outside of pull bar 4-2 is provided with external screw thread, and the two ends that pull bar 4-2 is positioned at through hole 3 are all fixed by nut and pad.
The mounting means of clamping bar 4: nut and pad are first installed in one end that pull bar 4-2 is provided with position-arresting disk 4-3, pull bar 4-2 be there is no one end of position-arresting disk 4-3 through after the through hole 3 of base 1, do not have one end of position-arresting disk 4-3 to install same nut and pad pull bar 4-2 again, finally do not have the one end of " hook " to be fixed by the external screw thread of pull bar 4-2 quiet chuck 4-4.
