Abstract
The utility model relates to a plug pin for a railway vehicle. The plug pin comprises a plug pin rod, a hand shank, an upper plug pin base, a lower plug pin base and an insertion hole. The plug pin rod is inserted into a guide hole of the upper plug pin base, a guide hole of the lower plug pin base and the insertion hole in sequence to lock a door. The upper plug pin base is provided with limiting grooves used for limiting the displacement of the hand shank. A limiting block is arranged at the top end of the plug pin rod, and the size of the limiting block is larger than the inner diameter of the guide hole of the upper plug pin base. The plug pin for the railway vehicle is simple in structure, safe and reliable. By arranging the limiting block at the top end of the plug pin rod, the situation that the plug pin rod falls off from the plug pin bases due to the fact that the hand shank breaks away from the plug pin rod is avoided. Furthermore, the joint between the hand shank and the plug pin rod is coated with a threaded fastening agent, a set screw is arranged on the joint, and one end of the hand shank is welded to the plug pin rod; in this way, the fixation reliability between the hand shank and the plug pin rod is improved, and the hand shank can be prevented from getting loose and breaking away from the plug pin rod.
Description
Technical field
The utility model relates to a kind of latch, particularly a kind of guideway vehicle latch.
Background technology
As depicted in figs. 1 and 2, handle is fixed on bolt rod, the jack that bolt rod inserts on upper and lower plug housing and car body is successively fixed door body, because jack in this vehicle is through-hole structure, when track vehicle operating, the sliding door latch on vehicle shakes because of vehicle, and bolt rod easily comes off and from jack, drops outside car, if bolt rod drops outside car from jack, can affect traffic safety greatly.
The bolt rod major cause that is easy to come off is: handle and bolt rod adopt common being threaded, and without auxiliary security measure, vibrations in vehicle operating process, impacts and easily causes thread connection to lose efficacy, and makes handle depart from bolt rod; Bolt rod is the consistent cylinder of external diameter in addition, without disconnecting prevention structure, once handle gets loose, will cause bolt rod to come off from upper and lower plug housing.
Utility model content
The utility model main purpose is to address the above problem and is not enough, provides a kind of simple in structure, safe and reliable, the guideway vehicle latch that bolt rod can not come off.
For achieving the above object, the technical solution of the utility model is:
A kind of guideway vehicle latch, comprise bolt rod, be fixed on described bolt rod handle, be fixed on upper plug housing and lower plug housing on a body, be arranged on the jack on car body, the jack that described bolt rod inserts on pilot hole and the car body of plug housing, lower plug housing is successively locked door body, on plug housing, be provided with the position-limited trough for limiting handle displacement on described, top at described bolt rod is provided with limiting stopper, and the size of described limiting stopper is greater than the pilot hole internal diameter of described upper plug housing; Described handle and bolt rod are threaded; On described bolt rod and described handle, be respectively arranged with tapped bore, by holding screw, be fixed on described tapped bore by further fixing to described bolt rod and handle; In threaded connection place, scribble screw threads for fastening agent.
Further, limiting stopper is cylindrical, and described columniform external diameter is greater than the pilot hole internal diameter of described upper plug housing.
Further, handle end and described bolt rod are welded and fixed.
To sum up content, a kind of guideway vehicle latch described in the utility model, simple in structure, safe and reliable.By bolt rod top, limiting stopper is set, avoids because handle departs from bolt rod, the bolt rod causing comes off from plug housing.Threaded connection place by handle and bolt rod is coated with screw threads for fastening agent, holding screw is set, the mode by handle end with bolt rod welding, and fixing reliability between enhancing handle and bolt rod, prevents getting loose between handle and bolt rod.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art latch;
Fig. 2 is the A-A face cutaway view of Fig. 1;
Fig. 3 is the structural representation of the utility model latch;
Fig. 4 is the B-B face cutaway view of Fig. 3.
As shown in Figures 1 to 4, bolt rod 1, handle 2, upper plug housing 3, lower plug housing 4, limiting stopper 5, holding screw 6, weld part 7, position-limited trough 8.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 3 and Figure 4, a kind of guideway vehicle latch, be applied on the interior baggage room sliding door of vehicle, comprise bolt rod 1, handle 2, upper plug housing 3 and lower plug housing 4, upper plug housing 3 and lower plug housing 4 are fixed on sliding door door body, on upper plug housing 3 and lower plug housing 4, be provided with the pilot hole inserting for bolt rod 1, in lower plug housing 4 bottoms, the relevant position of car body is provided with jack (not shown), for the fixing and locking of bolt rod 1, bolt rod 1 inserts plug housing 3 successively, jack on pilot hole and the car body of lower plug housing 4, the locking of pulling.
On upper plug housing 3, be provided with upper and lower two position-limited troughs 8, handle 2 pushes that the position-limited trough 8 of top is spacing when fixing, and bolt rod 1 bottom does not enter in the jack on car body, and sliding door can be opened; It is spacing when fixing that handle 2 pushes the position-limited trough 8 of below, and insert in the jack on car body bolt rod 1 bottom, sliding door locking.
On the top of bolt rod 1, be provided with limiting stopper 5, the size of limiting stopper 5 is greater than the pilot hole internal diameter of plug housing 3.Limiting stopper 5 can be square, taper etc., the present embodiment pref. cylindrical, and cylindrical external diameter is greater than the pilot hole internal diameter of plug housing 3.When shaking because of car body, when bolt rod 1 and handle 2 depart from, bolt rod 1 drops, but limiting stopper 5 is stuck in outside the pilot hole of plug housing 3, make bolt rod 1 cannot continue tenesmus, by limiting stopper 5, can prevent that bolt rod 1 from coming off from the pilot hole of upper plug housing 3 and lower plug housing 4 downwards.
For further increasing the fixing reliability of handle 2 and bolt rod 1, in the threaded one end of handle 2, tapped bore is set, on the surface of bolt rod 1, a tapped bore is set again, two tapped bore will overlap after handle 2 screw threads are fixed on bolt rod 1, holding screw 6 turn-knobs are set in two tapped bore, by further fastening to handle 2 and bolt rod 1.
The end of handle 2 and bolt rod 1 are welded and fixed, and end and the bolt rod 1 of handle 2 threaded one end are welded and fixed, and as shown in Figure 4, the position of welding is weld part 7, by weld part 7, has further improved fixing reliability between handle 2 and bolt rod 1.
Above-mentioned each threaded connection place all scribbles screw threads for fastening agent.
By above-mentioned be connected and fixed mode time application, improved greatly handle 2 and the reliability that bolt rod 1 is fixedly connected with, prevent that handle 2 and bolt rod 1 from departing from.A kind of guideway vehicle latch described in the utility model, has improved the reliability of latch, has avoided the disengaging between handle 2 and bolt rod 1, has prevented that bolt rod 1 from coming off from the pilot hole of upper and lower bolt rod, has improved traffic safety.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
