, just press from both sides now and introduces the present invention in conjunction with " e " type that is employed though thereby the present invention can be applied to any railroad track elasticity anchorage clip that a fixed supporting leg makes fastening devices maintenance folder that has.
Fig. 2 shows a fixed supporting leg 21 of the guide rail anchorage clip 20 of first aspect present invention.Though show whole guide rail folder 20, its fixed supporting leg 21 outer remainders be with, similar as " e " type folder, " PR " type folder or other similar folder.Fixed supporting leg 21 has an oblique angle 21b at its free end A place.And it is that groove 21a, its (21a) have an abutment face 21c that first latch-up structure of settling at interval with free end has a pallet.One fastening devices is that convex shoulder 200 (not showing overall picture) is used for clamping guide rail anchorage clip 20, and it has a housing 202 that forms a through channel 203 in it.One second latch-up structure that comprises a projection 203a is arranged on the top in passage 203.First and second latch-up structure one plays a supporting role and then constitutes a kind of prevention without permission with the mechanism of folder 20 from fastening devices 200 dismountings.The other parts of fastening devices can be to fastening devices shown in Figure 1B 100 similar.Can be during making folder or afterwards, with pallet 21a punching out on the fixed supporting leg of folder 20.Projection 203a is then made during making fastening devices 200.
Difference embodiment illustrated in fig. 3 and shown in Figure 2 is: the guide rail anchorage clip 30 that does not show overall picture has the fixed supporting leg 31 of a band oblique angle 31b, and it has first latch-up structure that comprises a projection 31a; Fastening devices 300 (not showing its overall picture) has a housing 302, and its (302) have a passage 303, is provided with second latch-up structure on the top of passage 303, and this structure has the groove 303b with an abutment face 303b.
When the fixed supporting leg 21 (31) with folder 20 (30) of the present invention inserts the passage 203 (303) of fastening devices of the present invention, projection 203a is on the fixed supporting leg 21, especially on the oblique angle 21b or the pressure of projection 31a on passage 303 tops force folder downwards slightly, and last till that always fixed supporting leg 21 (31) arrives till as shown in Figure 4 the positions that make the mutual snap engagement of first and second locking device.
To steal and destroy in order to prevent, should select the size and the position of latch-up structure, thereby make and fixed supporting leg is moved significantly, but this moving can not cause folder to produce permanent deformation again in order to dismantle folder.
Hope according to used be " right hand " type folder still " left hand " type folder to decide the latch-up structure (feature) with fastening devices be which the end place that places close passage.Any uses in " left hand " or " right hand " type folder if wish to make fastening devices, and its latch-up structure just can be arranged on the center of fastening devices so.In the case, because the top of this projection facing to increasing angles, just more is difficult to relevant folder is driven.
Fig. 4 has showed another embodiment based on the present invention embodiment illustrated in fig. 2, but this fastening devices 400 has an improved housing 402, and its (402) have passage 403 and projection 403a.The other end of housing 403 is extended, thereby thereby make the end of the adjacent protrusions 403a of passage 403 be cut a flared aperture 404, the upper surface of the free end A of fixed supporting leg 21 is exposed, so that (can introduce in more detail in conjunction with Fig. 5 A, a 5B and 5C below) special folder removal tool enters in it.Can see clearly from Fig. 4, how projection 403a by the situation of the abutment face 21c that puts fixed supporting leg 21, can hinder the dismounting of this folder thus.Compare with some prior art, folder 20 (30) of the present invention can so be made, that is, it can not easily be pulled down from fastening devices 200 of the present invention (300,400) along just impacting of R direction by hammer.But, in order to pull down this folder 20 (30), must apply downward pressure so that the fixed supporting leg downwards to fixed supporting leg free end A, thereby make projection 403a (203a, 31a) break away from, but also folder is driven along direction R from abutment face 21c (303b).
If can see from Fig. 5 A, 5B and 5C, remove folder and can utilize one custom-designedly to have the instrument 70 of a front end 71 to realize.The front end 71 of this instrument 70 is formed to such an extent that can be inserted into the free end A upper surface of the fixed supporting leg 21 (Fig. 5 A) that is arranged in folder 20 and the flared aperture between the housing 402.Along with the front end 71 of instrument 70 is further pushed flared aperture 404, the free end A of the fixed supporting leg 21 of folder 20 is little by little pushed downwards, thereby make pallet 21a contact (Fig. 5 B) from projection 403a disengagement and with the table top 72 of instrument 70, fixed supporting leg 21 just can be promoted (Fig. 5 C) along passage 403 then.
Shown in the above-described embodiments, first and second latch-up structure of this embodiment has an abutment face and a projection, folder or fastening devices both one of can have abutment face.But from the angle of making, for example make folder have abutment face by a pallet and make fastening devices have projection more satisfactory and make easier.
Though the above-mentioned embodiment of the invention has adopted the fastening devices of a casting, the present invention also can be applied to the steel material fastening devices that a pressure processing is made, and its situation is as 6A, 6B and 7A, 7B introduce in conjunction with the accompanying drawings below; Perhaps also can be used to a fastening devices (not shown) of making by the rolling steel plate.
Shown in Fig. 6 A, 6B, the steel fastening devices 500 that one pressure processing is made has a housing 502, shell 502 is formed to such an extent that a passage that runs through 503 arranged, the top of passage 503 is configuration second latch-up structure on the position of end part interval in an end of adjacent channel 503 but therewith, and this second latch-up structure has one by form the projection 504 that a groove is made on the top of housing 502.Can more clearly see projection 504 clearly in Fig. 6 B, Fig. 6 B shows that one is parallel to the sectional view at top of the housing 502 of passage 503.The shape of projection 504, size depend on the shape and the size of the abutment face of the effect of being mated.In thick 10 millimeters housing 502, the length of its passage 503 is 70 millimeters, and 504 of its projections can be 45 millimeters in distance passage 503 1 ends to be located to make, it be made height be 2 millimeters, wide be that 5 millimeters, radius of curvature are 3 millimeters.
Fig. 7 A and 7B have showed the fixed supporting leg 51 of the rail anchorage clip 50 (not whole expression) of the present invention first and third aspect, and folder 50 is similar to the folder among Fig. 2,3 and 4 in many aspects.Fixed supporting leg 51 has a chamfer at its free end A place, is groove 51a from free end A interval one short distance one pallet being arranged.Groove 51a has two abutment face 51c and 51d, and their (51 courts see away from the order of free end A along fixed supporting leg) are extended respectively down and up.In the present embodiment, the surperficial 51d that extends up is bigger than the surperficial 51c gradient of extending down.Shown in present embodiment in, with regard to extensional surface 51c down, about 30 ° of the angle of the longitudinal axis of its relative fixed supporting leg 51; And be about 90 ° towards the angle at the top that extends upward surperficial 51d, its base portion has a radius 1R.
In the folder embodiment shown in Fig. 7 A and the 7B, the edge that groove 51a is made the free end A of its most close supporting leg 51 is that 10 millimeters, its (51a) are 12.5 millimeters along the length of supporting leg 51 bearing of trends apart from the distance of this end A, is 2 millimeters deeply.The base portion radius of extensional surface 51d is 1 millimeter up.
In the embodiment that introduces more previously, groove against projection and for the surface that hinders folder dismounting be vertical substantially.Therefore, be difficult to folder is pulled down with common mode.But, at Fig. 6 A, 6B, among the embodiment shown in 7A and the 7B, the surperficial 51c of Yan Shening is tilted with quite little angle down.Clearly, such folder still provides the obstruction more much bigger than the folder that does not have locking device to unwarranted dismounting, but the obstruction that provides still is smaller, and this is because make the motion of crossing projection 504 to veneer 51c require less power.However, needed in the case power still is enough to prevent move away in the fastening devices 500 that folder 50 is worn from use.
If wish to hinder the dismounting folder biglyyer; Can make abutment face 51c that one steeper angle of slope is arranged, preferably angle value is greater than 40 °.
The angle of internal friction of upwardly extending surperficial 51d also can change, but in the embodiment shown in Fig. 6 A, 6B, 7A and the 7B, this angle is selected that a kind of retainer is provided, when being loaded in the fastening devices 500 at folder 50, this retainer arrive with projection 504 against, thereby guarantee that folder 50 can not be pushed over it easily and be the correct installation site on the operating position of setting.Specifically, by the longitudinal axis of going up a relative fixed supporting leg 51 of configuration in place is that angle of slope in the 35-90 ° of scope suitable precipitous extends upward surperficial 51d, just can make when folder is installed to the tram to drive the required power of folder and increase suddenly, thereby prevent that folder from exceedingly being packed into.
One adopts folder of the present invention to be configured a pallet (rather than configuration projection as shown in Figure 3) as shown in Figure 2 on its fixed supporting leg, just can be used to existing, do not adopt in the fastening devices of the present invention.Can allow the railway system only to keep a kind of stock of folder like this, this folder can utilize the attendant advantages of the fastening devices that has embodied the present invention, but with traditional folder with do not adopt existing fastening devices of the present invention mutually the situation of assembly compare and eliminated defective.
Be designed to provide in the assembly that stops dismounting, the shape of fastening devices is retrofited the biglyyest, so that allow to come clamper for disassembling with specialist tools, another advantage is to expect: where the folder corrosion meeting in fastening devices becomes a problem.If corrosion, the folder of prior art then can not take out from fastening devices easily.If but the employing the sort of fastening devices that an excision part is arranged as shown in Figure 4 just can easily put on downward pressure on the free end of folder fixed supporting leg, thereby easily abolish the adhesion between folder and the fastening devices.If fastening devices has D tee section (rather than circular) passage, the fixed supporting leg of folder can deflection enter in it because it can provide bigger space, and above-mentioned effect then is biggest advantage.
